Start by looking at yourself simple option– installing a new one of the same type instead of a faulty one is hardly worth it. Even a schoolchild can cope with this, knowing that first you need to turn off the voltage, and then unscrew the cartridge itself, loosen the clamping screws of the terminal block, and so on. This question is mainly of interest to those who want to “modernize” a chandelier in order to use an energy-saving lamp instead of the traditional “Ilyich light bulb” - for this they often have to replace the chandelier socket. Let's look at this in more detail.

It is pointless to recall the advantages of various halogen and others. Once they have been chosen, then all their advantages are already known and appreciated. But why change the cartridge in a chandelier? The whole point is a mismatch in the parameters of the socles (diameter and thread). Without delving into the classification of cartridges and the differences between their types (, E40), it is enough to indicate that it is necessary to install one of two - “14” or “27”. E40 sockets are intended for street lamps.

1. Turn off the machine in the apartment (entrance) panel. Hence the conclusion - it is advisable to replace the cartridge in daylight hours. What if this condition cannot be met for some reason? Install near the location of the chandelier table lamp so as not to work in complete darkness.

If the wiring in the apartment is done “wisely”, then the sockets and ceiling lamps are routed along different lines (although the author has also encountered “pleasant exceptions”). But we turn off the input machine for safety. This means that the sockets will also be de-energized.

In an apartment, if an internal shield is installed, it’s even easier. It is enough to turn off the corresponding machine.

2. Turn the wall (or other) chandelier switch to the “off” position. If for some reason it is undesirable to turn off the input machine.

3. Using an indicator probe, check that there is no voltage on the terminal block of the chandelier, through which its wires are connected to the intra-apartment line.

Why is this necessary if everything is already de-energized? According to the rules of electrical installation, a switch (circuit breaker) is installed on the phase line, before the lighting fixture. Now the question is - does everyone know this? And of those who are “in the know,” how many comply with this provision? It’s better not to take risks and check the presence/absence of potential at all terminals of the block.

4. Disconnect the chandelier wires. Here you need to figure out what is more convenient to do - leave it hanging or first remove it from the hook (“butterfly”).

5. Lower the chandelier down. Replacing sockets at a height, especially if the lamp is quite large, with several bulbs, is not the best solution.

6. Remove the cartridge. First, it unwinds, after which the wires are disconnected from its ceramic block. Next, remove the lower part of the body. Its fastening is carried out differently, depending on design features chandeliers. The procedure is easy to determine by visual inspection.

If the chandelier has been in use for a long time, then you need to pay attention to the condition of the wires inside it (from the socket to the block). At this stage it is easy to replace them with new ones.

Next is reassembly and connection. And here is one more piece of advice - this must be done immediately. If you leave the installation of a new cartridge “for later,” then it is not a fact that such work will go quickly. Those who do this for the first time have difficulties, since much is forgotten already on the second day. Proven by practice.

If the connection of the chandelier was previously made by twisting, then it is advisable to organize a new connection using terminal blocks.

For household use It is better to purchase products from WAGO. It is much more convenient to work with spring-loaded contacts. Learn about the range and specific application of these products.

To restore the chandelier to full functionality, it is not necessary to replace the lamp socket, which does not light, even if the filament is not broken. Depressurization of the flask (another probable malfunction) is a rare occurrence.

Typical faults

  • “Retraction” of the tongue. This often happens if, when replacing light bulbs, they are screwed in too hard. Therefore, the central contact of the base does not reach it. It is not difficult to lift it a little, for example, with a thin screwdriver.
  • Carbon deposits on the cartridge tongue. As a result, contact is broken. You can clean it with fine sandpaper. If it is not at hand, the plaque can be easily removed with the tip of a knife.
  • Poor contact where the wires are attached. Pulling the screws is a matter of seconds.

Practical tips:

  • Before you start work, you need to take care of your own safety. What and where to turn off, how to check that there is no voltage on the wires is indicated above.
  • In any case, if you have to work on a chandelier, you need someone to stand nearby and help, and at the same time, insure.

An electric light bulb socket is a device that is the connecting unit between the lamp and the incandescent element. In addition, using additional fasteners, a lampshade or shades can be hung. This part transmits current through wires. The screwed-in burnt element can be easily changed due to the simplicity of the product body.

Product marking

Depending on the diameter of the threaded part of the assembly, the products have several varieties:

Connecting the electric socket

To understand how to connect a light bulb socket, you need to have a good understanding of its structure. The central contact is made of brass. It presses against the ceramic liner. For this purpose, there is a threaded steel plate on the reverse side. A screw is screwed into it and passes through ceramic and brass.

The screw is tightened with good force, because it passes through the part to the contact. electricity. A side brass plate is placed nearby, which is attached according to the same principle.

When connecting the wires, rings are formed on them for fastening. They pass through its central hole in the body and are fixed on steel plates. The phase from the network is supplied to the central contact.

After this, a bushing with a thread for the light bulb is screwed on top. Then the lamp is selected.

Product fastening

Typically, the socket in chandeliers or lamps is mounted at the bottom of the housing. It is unacceptable to place any weight on the wires. For fixation, the chandelier has a hole at the bottom into which a plastic sleeve is inserted. The wiring runs into it and is fixed with a bolt. A more reliable fastening is a metal tube. Wires are passed through it. The nuts located on it allow the installation of shades and chandelier caps.

For installing lamp shades or wall lamps There are special cartridges. They have a thread on the outside. The attachments are pressed using plastic bushings that are screwed onto the threaded part of the cartridge.

It should be remembered that you cannot install a high-intensity light bulb, because the plastic washers begin to melt.

Reasons for replacing the design

Over time, the product requires replacement. The need arises due to the following circumstances:

Before replacing the cartridge, here are some tips to keep in mind:

Dismantling and installation work

Armed necessary tools, you can begin dismantling the old structure and installing a new product . The step-by-step instructions are as follows:

Power is supplied to the network and the device turns on. If the work is done correctly, the light should light up.

An electric socket is a product that is present in any lamp. Over time, the structure fails. The reason may be rust or a crack in the housing. Main, notice it in time and work to replace it.

When a light bulb burns out in the house, and replacing it does not bring results, then it is necessary to change the socket in the chandelier. This breakdown is the most common; it can be easily fixed with your own hands without special knowledge and tools.

The main reasons for replacing the cartridge

It is necessary to replace the socket in a chandelier not only due to manufacturing defects, but also due to design features. If the lamp closed type, the temperature inside the flask increases greatly. Sometimes this leads to melted wiring.

In old sockets, contact with the lamp deteriorates over time. This can cause frequent breakdowns of the latter. After incandescent lamps burn out, sometimes fumes form on the terminals, which leads to poor contact. Simple cleaning rarely brings positive results, so the holders are replaced.

Another reason for replacement is the desire of people to switch to economical LED bulbs. Since they are produced with a smaller base, there is a need to change the seat in the lamp. All holders have an identical design. They differ only in the diameter of the thread.

How does a standard cartridge work?

To replace the cartridge in a chandelier, you need to understand its structure and types. For a 220 V network there are 3 types of this product:

Depending on the type used in the lamp, you need to choose one type or another. There are such parts of the cartridge:

  • cylindrical body;
  • bottom;
  • ceramic liner.

The first contains a sleeve with an Edison thread into which the lamp is screwed. The holder body, depending on the model and purpose, can be made of the following materials:

  • plastic;
  • carbolite;
  • ceramics;
  • metal;
  • silicone

Old models were made of ceramics. But when high temperatures they crumbled and spoiled. Nowadays the most common material is plastic. Products should be used according to labeling, since excess power electric lamps with prolonged use will lead to a change in the properties of the plastic, and consequently, to its destruction. Even in modern ceramic cartridges, contacts burn out at high temperatures.

The most common types of holders used in everyday life are E14 and E27. Their differences lie in the method of fastening, which can be:

  • suspended from the ceiling with threaded washers;
  • with a straight flange, which allows you to fix the product on the surface;
  • with an inclined flange for surface mounting.

When the lampshade is attached to the support, washers are used to mount and secure the holder. The holders for attaching to the nipple have clamps instead of screws. This allows you to connect conductors without violating their insulation. Although threaded holders are easier to use, they are less durable. This is especially true for cartridges used for a long time.

The process of replacing the cartridge in a chandelier

To replace the socket in a chandelier, you must perform the following steps:

  • turn off the electricity supply at the panel;
  • disconnect the electrical wiring;
  • remove the chandelier from the ceiling;
  • disassemble the lamp;
  • remove the faulty cartridge;
  • set whole;
  • After replacement, install the chandelier.

Turning off the light on the dashboard

Before replacing the cartridge, you need to turn off the power supply to the room. To do this, there are machines on the panel that provide power ceiling chandelier, transfer to inactive state.

Disconnecting wires

All wires that supply power to the lamp are insulated and routed to each side to prevent a short circuit.

Removing a chandelier from the ceiling

To remove the chandelier, you need to take an indicator screwdriver and a stepladder. First you need to check the switch to make sure there is no electricity. Then do the following:

  • remove such fragile parts from the chandelier as the lampshade, decorating elements, lamps;
  • unscrew the fixing screw and the cap that covers the wire connection under the ceiling;
  • if there is a hook under the hood, the wires are disconnected and separated to exclude short circuit;
  • if there is a strip, loosen the clamping bolt or, if necessary, remove it.

Fixing the chandelier on suspended ceilings carried out using disposable butterfly fasteners. Therefore, it is advisable not to remove them. Otherwise, you should purchase a new mount in advance.

Disassembling the lamp

Most chandeliers have 3 or 5 seats for lamps directed in different directions. If the chandelier was working before dismantling, you need to wait until the temperature inside the lamp drops. First, the lampshades are removed. In old-style chandeliers they are fixed by means of threads. Others are held on with special latches or small bolts.

A plastic threaded ring is most often used to secure this element. It is screwed onto the external thread of the holder, so you need to be careful not to break the insulating part of the element.

The method of dismantling depends on the type of structure and method of fastening in the housing of the lighting device. Most often, fixation occurs with several bolts. The part is removed immediately or it is disassembled, removing the core. In this case, remove the cartridge latch, take out the middle part and disconnect the wires. The last thing to unscrew is the nut securing the housing.

When the screw terminal socket needs to be replaced, the screws should be loosened and the wires pulled out. Some E14 type holders have terminal blocks. In most cases, they are disposable, so they need to be replaced.

The ceramic cartridge is dismantled as follows:

  • the plates are pressed out from the central contact;
  • unscrew the bolts from the plate, which is located opposite the ceramic base;
  • The central terminals are bent to the level of the side contacts.

Sometimes it is enough to clean ceramic products and tighten the terminals to ensure high-quality operation of the cartridge.

Installing a new cartridge

To replace the socket in the lamp, you need to connect all the wires. They start in bottom part products, and rings are formed from the stripped ends. They are installed on screws, fixed with plates and clamped. If fastening is carried out using terminals, the bare ends of the wires are twisted so that the hairs do not bristle. Then they are inserted into the clamps and clamped with pliers.

The phase is supplied to the central contact.

It is important to ensure that the fasteners are secure to prevent short circuits or poor contact. Otherwise, the wires will begin to spark, which will lead to damage to the cartridge.

Additionally, check whether the cross-section of the wires matches the power consumption of the chandelier. Upon completion of the replacement, the lamp is assembled and installed in the reverse order.

How to properly disassemble the cartridge?

To properly disassemble the holder, it is necessary to determine how the cylinder is fixed. If these are latches, they must be carefully bent so as not to break.

How to properly remove the base from the socket?

Sometimes it is difficult to pull the holder out of the chandelier because it is firmly fixed inside. When unscrewing, only the flask can be removed. To solve this problem, you need to unscrew the housing cylinder, holding it by the bottom. After this it will be much easier to remove the base. If the upper part of the product does not unscrew, you need to remove it with pliers.

One of the main components of a chandelier or lamp is an electric socket, through which not only the light bulb is fixed and current is transmitted to it, but also the lampshade and other elements for controlling the light source are attached.

The design of the product consists of the following elements:

  • cylindrical body;
  • internal threaded sleeve;
  • ceramic insert;
  • a pair of brass or copper contacts;
  • bottom;
  • fasteners.

The design of the product body eliminates the possibility of electric shock when screwing in the light bulb. This is due to the fact that when the central contacts touch, the base is inside the cartridge.

Types of cartridges

Structurally, several types are distinguished according to the method of attaching the light bulbs:

  1. Screw threaded(the incandescent lamp is screwed inward). Suitable for standard incandescent lamps.
  2. Pin(fastening is carried out using fastening tabs or pins located on the outer surface of the product). Used for fluorescent, halogen and.

The material used to make the case is:


The principle of operation of all cartridges is identical, the only differences are dimensions and design. All products are designed for operation in a 220V power supply.

The following types are distinguished (the value “E” with a number is used for designation, where the number corresponds to the diameter of the sleeve):

  1. E5 and E10. They are rarely used due to the consumption of a considerable amount of current with insignificant light output.
  2. E14. The product is small in size, used with decorative lamps, so-called “minions”, of identical diameter. Their power does not exceed 60 W.
  3. E27. The most commonly used threaded socket designed for use with conventional, fluorescent, LED and halogen lamps.
  4. E40. This type is intended for street lighting, where powerful large lamps are used.

Chuck selection

When choosing this product, first of all, you should give preference to a well-known and trusted brand.

To avoid difficulties with fastening, the design of the new socket must correspond to the type of product previously used in the chandelier. It is better to give preference to a ceramic product due to its reliability during operation.

Basic selection requirements:

  • the power of the lamp that is planned to be connected;
  • diameter corresponding to the type of cartridge;
  • marking;
  • parameters: dimensions, power;
  • the price should not be too low.

The cost depends on many factors, in particular the type of product and its manufacturer. Today the market provides consumers with a wide choice of both Russian and imported brands.

The price range is quite large:

  1. Type E27:
    • domestic production – 25 rubles;
    • China – 45 rubles;
    • Italy – 130 rubles.
  2. Type E14:
    • domestic production – 20 rubles;
    • China – 20 rubles;
    • Italy – 90 rubles.
  3. For halogen lamps:
    • domestic production – 15 rubles;
    • China – 30 rubles;
    • Italy – 150 rubles.


How to change the cartridge in a chandelier

Replacing the product is not particularly difficult and does not require electrical experience, but it does require caution and compliance with all rules and recommendations.

Reasons for replacement

First of all, the need to change the product is indicated by the lamp not glowing when the switch is activated. This is due to rusting of the sleeve or central contact. As a rule, stripping does not have a positive effect.

Replacement is required if:

  1. The presence of cracks and other defects on the outer part of the body;
  2. When internal elements come into contact, a short circuit occurs.
  3. Exit from working state.
  4. The service life is 5 years.

Required materials and tools

During the work you will need:

  • replacement product;
  • terminal blocks for connecting electrical wires;
  • indicator mini-tester (screwdriver);
  • insulating tape;
  • construction knife with replaceable blades.

Step-by-step replacement guide

Replacing the socket in a ceiling lamp is carried out in the following sequence:



 Place the chandelier on a table or other convenient surface, disassemble it, removing all the shades and unscrewing the bulbs so as not to break them.

Checking work

After attaching the chandelier to the ceiling, a lamp is screwed into the socket and electric current is supplied. If the replacement work is done correctly and all contacts are connected, the lamp will glow.

If, after replacing the product, any problems are detected (flashing of the lamp or its burnout), their causes should be found. Alternatively, it could be an incorrect connection of the current supply wires.

  1. Carry out the replacement without turning off the power to the room, is strictly prohibited, often leading to tragic consequences.
  2. If problems are detected in the main it is necessary to completely or partially replace it.
  3. Sometimes cartridges initially have lead wires, so when connecting various types wires, for example, aluminum acts as the main one, and copper comes from the lighting device; it is advisable to use special terminal blocks for connection. If there are none, the wires should be connected, twisted and covered with insulating tape.
  4. Before removing the chandelier, you should remember or sketch the connection diagram, which will eliminate the possibility of incorrect connection.
  5. If the reason for withdrawal ceiling lamp If the cartridge is out of fret, you can try to repair it.
  6. Often, brass plates come off, oxidize, or rust. In this case, they can be cleaned with sandpaper. You should also inspect the contact fasteners located under the ceramic insert. If necessary, they are cleaned and tightened. After a thorough inspection, the socket is assembled and the lamp is screwed into it, the ends of the lamp wires are placed in a carrying case. The result of a properly carried out repair will be the emission of light from the lamp.

Sometimes it is not possible to remove an incandescent lamp from the socket - the base gets jammed, and when the lamp is unscrewed, only the glass bulb is removed.

In order for the cartridge to be used in other chandeliers in the future, it is necessary to unscrew the cylindrical element of the product body, holding it by the lower part. If these manipulations do not give a positive result, you can unscrew the base using pliers, taking its edge and turning it in the socket.

Do you have to replace a light bulb socket with a new one, but you don’t know how to do it correctly so as not to damage important wires and components? For such a simple job, you don’t want to call an electrician, whose services will be quite expensive, right? Or do you need to upgrade your home electrical system by replacing individual elements? We will help you understand the features of connecting various cartridges - the article discusses the main types and markings of factory-made electric cartridges. Instructions for connecting a cartridge with threaded terminals are also provided and discussed existing options its fastening in lighting installations. Selected visual photos With

An industrial or home electrical network consists not only of wires and lamps, but also of many electrical installations that serve for control or communication individual parts contour.

The socket connects the lamp base to the electrical cable and at the same time fixes it in a lamp, chandelier, or simply holds it suspended.

The problem of quickly replacing lamps arose as soon as electric lighting was invented, that is, at the end of the 19th century. The first lamps had bases, but the methods of connecting them to the wires were different and had no classification.

In 1881, Edison patented the first threaded type base and cartridge for it. Thus, the most popular types of bases and sockets have remained relevant for more than 130 years.

Of course, they were originally invented. Then gas-discharge and LED ones appeared; their installation required both already familiar and structurally different types of cartridges.

The same standard sizes make replacement easier: instead of an incandescent lamp, a more economical alternative can be screwed into the same socket - an LED with a threaded base or a filament bulb

For the manufacture of modern cartridges they use various materials, among which you can find traditional metal and ceramics, as well as heat-resistant polymers and even silicone.

The last option is most often used to create design compositions. Silicone products are equipped with a 1 m electrical cord and are painted in all the colors of the rainbow.

For example, incandescent and stylized lamps are equipped with threaded lamps.

But some products can only interact with one option. Let's take a closer look at them design features And specifications, which you need to rely on when choosing.

No. 1 - popular threaded options

Sockets with internal threads are designed for lamps with a threaded base. The sizes are usually designated the same: for example, for a lamp with an E14 socket, a corresponding E14 socket is required, although an adapter from E27 to E14 is possible.

The numbers 14 and 27 indicate the diameter, with 27 often considered the classic size and 14 called the minion.
