Lamp holder: installation and connection

In its function, the bulb holder is a special element that helps to fix the light source inside the device connected to the network. Any repairs related to the installation of electrical equipment, require mandatory performance of calculations of the performance of wiring in the room. These activities are often directly related to the owner's wishes for design, design projects are also taken into account. So, for the creation of an original dwelling in its design, installation of various types of lighting equipment may be required, which inevitably entails the necessity of mounting various cartridges. Therefore, it is necessary to understand how to connect the bulb holder for the bulb correctly, that is, in compliance with all safety rules.

What does the cartridge consist of?

In the process of working with electricity, it is very important not to forget about clearly regulated rules that can not only provide the equipment with normal work, but also preserve health to the owners of housing.

Therefore, before thinking about how to install a bulb for a light bulb, you need to remember a few mandatory conditions:

• Firstly, the element itself and the lamp mounted in it must correspond to each other. This means that the base of the lighting fixture should be suitable;
• Secondly, do not forget about the periodic replacement of electrical equipment, which explains the need to connect the lamp directly to the cartridge, and not directly from the network.

The principle of this element is as follows: by means of a special screw, one of the wires is attached to the side contact, and the other is connected to the central screw by means of the same screw.

The main components of this part are the sleeve, body and central contact. All of them are fixed on the insulator.

Types of cartridges for lighting electrical appliances

It's no secret that a bulb holder can have any configuration, as a result of which there is a division of this element into 4 large categories.

1. A threaded cartridge with a diameter of 27 mm. It is most often used in standard apartments and private houses, since such a sample is equipped with the most common base and suitable for a standard lighting source.
2. 14 mm threaded chuck. This type is used in devices equipped with small-sized incandescent lamps. Such coverage is usually zonal, that is not common, since the range of such equipment is not large.
3. A cartridge with a diameter of 40 mm. The main lamps for such samples are large models with high power (500 W and more). The scope of such equipment is outdoor lighting (streets, roads).
4. A special type, called bayonet, is resistant to even the strongest vibrations. Such elements are very often used for transport, in addition, they differ from other threaded samples in that they are not screwed in according to the standard principle, but are inserted, because in connection with heavy loads and vibration, the standard cartridge can fall out.

Technical features of various lamp cartridges

It is important to note that the bulb holder can be different not only in its type, but also in accordance with the design features. Therefore, according to this parameter, several varieties can be distinguished, such as pendant (used for rooms with a high humidity level), equipped with a special fastening mechanism, straight, inclined and others.

Patterns of cartridges differ among themselves. So, the most popular are samples made of plastic or porcelain (they are more tolerant of high temperatures).

Next, you should consider in more detail how to disassemble the bulb holder for the bulb as correctly as possible and, equally importantly, safely.

Dismantling the lamp chuck

In order to accurately divide the equipment into its component parts, it is first necessary to unscrew the upper fragment of the device so that its base is visible from the ceramic, which, in turn, is connected to the contacts. Then, this part must be removed and detached from all adjacent elements.

It is very important to understand how the bulb holder interacts directly with the wire. Connecting the equipment to the stationary switch must necessarily be accompanied by the connection of the phase cable to the central contact. After this, it is important to make sure that the received system works reliably. For this, it is required to apply a light source to the cap to understand that the contact resulting from the assembly is bent at a distance of at least 2 mm. Completing the assembly of the entire element by winding the body in the form of a cylinder.

The next step is to look in more detail at how to correctly replace a decommissioned instrument.

Replacing the cartridge

It is extremely important to remember that the installation of the bulb holder must take place with strict adherence to safety precautions.

First of all, it is necessary to de-energize the shield, that is, to disconnect those automata in it that are directly responsible for the illumination. After this, it is necessary to remove the lighting device in which the lamp with a defective cartridge is installed. Do this always in order to avoid the potential risk of harm to health.

After removing the lamp you can start disassembling the cartridge, the process of which was described above.

As a rule, the fastening of this element of the bulb falls on a tube made of metal. This type of fixation is the most popular, because with its help it is possible not only to give the whole structure the greatest strength, but also to realize numerous design decisions due to the ability of such a mechanism to withstand the heavy load that falls precisely on the metal tube. In addition, this part can be equipped with various nuts, which allows you to fix on the lamp a variety of plafonds and decorative lampshades.

If the inside wires are much older, they are also recommended to be replaced. It is not difficult to do this, it is enough just to get old cables out of the tube, and in their place to stretch new ones.

The work is finished by assembling the cartridge in the reverse order. It is especially important to be careful, since any, even minimal, insulation damage can cause short circuits.

Possible repair of lamp holder

Thinking about how to make a bullet for a light bulb with your own hands, the owners can face a number of problems related either to the difficulties of installation, or to the elementary lack of experience of such work. Nevertheless, there are situations when it is extremely necessary to dismantle or repair installed equipment. For example, the light source starts to work with less power, a specific sound (buzzing) appears, and sometimes the smell of burning.

If any of these problems occur, you need to unscrew the device and carefully examine its cartridge. If his contacts have acquired a black color, then it will be enough just to clean them.

It also happens that when the bulb is unscrewed from the lamp, the bulb can come unstuck from the base. To fix this problem, it will be most correct to unscrew the base completely, while removing the body of the cartridge. You can do this either manually or with the help of, for example, pliers.

Anyway, but high-quality repairs require a complete disassembly of the cartridge and verification of all its connections. If all the above rules are followed, the lighting equipment will last a long time and will not bother the owners with frequent breakdowns.
