According to its functional purpose, a light bulb holder is a special element with which the light source is fixed inside the device connected to the network. Any repair work related to the installation of electrical equipment requires mandatory calculations of the performance of the wiring in the room. These activities are often directly related to the wishes of the owner regarding the design, and design projects are also taken into account. So, in order to create a home that is original in its design, it may be necessary to install lighting fixtures of various types, which will inevitably entail the need to install various cartridges. Therefore, you should figure out how to connect the bulb holder correctly, that is, in compliance with all safety rules.
What is a cartridge made of?
In the process of working with electricity, it is very important not to forget about clearly regulated rules that can not only ensure normal operation of the equipment, but also preserve the he alth of homeowners.
Therefore, before thinking about how to install a light bulb socket, you need tofirmly remember a few prerequisites:
- firstly, the element itself and the lamp mounted in it must match each other. This means that the base of the lighting fixture must 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 device principle of this element is as follows: with a special screw, one of the wires is attached to the side contact, and the other is connected to the central one using the same screw.
The main components of this part are the sleeve, body and center contact. All of them are fixed on the insulator.
Types of sockets for electrical lighting fixtures
It's no secret that the bulb holder can have any configuration, as a result of which there is a division of this element into 4 large categories.
- Threaded chuck having a diameter of 27mm. Most often used in standard apartments and private houses, since such a sample is equipped with the most common plinth and is suitable for a standard light source.
- 14mm threaded chuck. This type is used in appliances equipped with small incandescent lamps. Such lighting is usually zonal, that is, not general, since the range of such equipment is not large.
- Chuck with a diameter of 40 mm. The main lamps for such samples arelarge-sized models with high power (500 W or more). The scope of such equipment is outdoor lighting (streets, roads).
- 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, since due to heavy loads and vibration, a standard cartridge can simply fall out.
Technical features of various lampholders
It is important to note that the light 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 hanging (used for rooms with a high level of humidity), equipped with a special fastening mechanism, straight, inclined and others.
Differ among themselves and cases of cartridges. So, the most popular are samples made of plastic or porcelain (they are more resistant to high temperatures).
Next, we should take a closer look at how to disassemble the bulb holder as correctly and, equally importantly, safely.
Disassembly of the lampholder
In order to accurately divide the equipment into its component parts, it is necessary, firstly, to unscrew the upper fragment of the device so that its ceramic base is visible, which, in turn, is connected tocontacts. Then this part must be removed and disconnected from all elements adjacent to it.
It is very important to understand how the bulb holder interacts directly with the wire. Connecting the equipment to a fixed switch must be accompanied by the connection of the phase cable to the central contact. After that, it is important to make sure that the resulting system works reliably. To do this, you need to apply a light source with a base in order to understand that the contact obtained as a result of the assembly is bent at a distance of at least 2 mm. The assembly of the entire element is completed by winding the body in the form of a cylinder.
Next, we should go into more detail on how to properly replace an out-of-service device.
Replacing cartridge
It is extremely important to remember that the installation of the light bulb holder must be carried out with strict observance of safety regulations.
First of all, you need to de-energize the shield, that is, turn off those machines in it that are directly responsible for lighting. After that, it is imperative to remove the lighting device in which a light bulb with a faulty cartridge is installed. This should always be done to avoid potential he alth risks.
After removing the lamp, you can proceed to disassemble the cartridge, the process of which was described above.
As a rule, the fastening of this light bulb element falls on a metal tube. This type of fixation is the most popular, since with its help you can not only give the whole structurethe greatest strength, but also to bring to life numerous design solutions due to the ability of such a mechanism to withstand the heavy load that falls on the metal tube. In addition, this part can be equipped with various nuts, which allows you to fix a variety of shades and decorative lampshades on the lamp.
If the wires inside are significantly outdated, they are also recommended to be replaced. It is not difficult to do this, you just need to get the old cables out of the tube, and stretch new ones in their place.
The work ends with the assembly of the cartridge in the reverse order. It is especially important to be careful here, since any, even minimal damage to the insulation can cause short circuits.
Possible light bulb socket repair
Thinking about how to make a bulb holder with their own hands, the owners may encounter a number of problems associated either with installation difficulties or with an elementary lack of experience in such work. However, there are situations when it is imperative to dismantle or repair the installed equipment. For example, the light source starts to work with less power, a specific sound (buzzing) appears, and sometimes a burning smell.
If any of these problems occur, you need to unscrew the device and carefully examine its cartridge. If his contacts have become black, then it will be enough just to clean them.
It also happens that when unscrewing the light bulb from the lamp, the bulbmay come off the plinth. To fix this problem, it would be best to unscrew the base to the end, while removing the cartridge case. This can be done both manually and with the help of, for example, pliers.
One way or another, but a quality repair requires a complete disassembly of the cartridge and checking all its connections. Subject to all the above rules, lighting equipment will last a long time and will not bother the owners with frequent breakdowns.
