Description

Technical Field

[0001] The utility model belongs to the technical field of wire and cable processing, in particular to a prefabricated branch compression joint with an emergency socket. Background Art

[0002] Prefabricated branch cables are commonly used in the power supply systems of high-rise buildings. They have the following characteristics: easy installation: branches are prefabricated in the factory, and on-site construction is simple and fast, which can significantly shorten the construction period. High reliability: branch joints are professionally processed, with stable and reliable quality, reducing potential faults. Space saving: no need to make a large number of cable joints, which can effectively utilize building space. Neat and beautiful: wiring is neat and the appearance is good. Good electrical performance: it can ensure good electrical conductivity and insulation performance.

[0003] Traditional prefabricated branch cables are composed of a multi-core cable main line (1), branch cables (3), and an injection-molded branch body (4). Their conductors are crimped together by corresponding single conductors in the main cable and single conductors in the branch cables using C-shaped tubes to achieve electrical connection. For the specific components of the main cable and branch cables, see Figure 1 .

[0004] During the use of prefabricated branch cables, there may be an accident where the power supply to a distribution box of a certain branch fails, resulting in a power outage. When it is pitch black in the electrical shaft and there is no temporary power socket available, it is very difficult to repair the faults of the branch distribution cabinet.

[0005] In view of the above deficiencies of the prior art, the present application proposes a prefabricated branch cable compression joint with an emergency power socket, which is used as a backup power socket for emergency lighting, detecting lines, and using electric tools for emergency repair when a power outage occurs in the branch circuit distribution line. Content of the Utility Model

[0006] The purpose of the utility model is to propose a prefabricated branch compression joint with an emergency socket, adding a power socket to the injection-molded prefabricated branch cable compression joint to provide power when a line fault in the branch distribution box causes a power outage, for temporary lighting in the shaft, emergency use of electric tools, etc.

[0007] To solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A prefabricated branch compression joint with an emergency socket, comprising a main cable, branch cables, a conductor compression C-shaped tube, an injection-molded branch body, and an emergency socket. The conductors of the main cable and the branch cables are compression-connected through the conductor compression C-shaped tube. One wire is connected to the emergency socket from each of the phase line (any one) and the neutral line on the main cable. Since the voltage obtained by the three-phase five-wire system (or the three-phase four-wire system) adopted by the cable is 220V, the main cable, the branch cables, and the emergency socket are injection-molded into an integral whole through the injection-molded branch body.

[0009] Furthermore, the emergency socket is a two-hole round anti-electric leakage and moisture-proof socket with a voltage of 220V (only for emergency use), and the emergency socket should meet the basic requirements of the electric tool plugs on the market.

[0010] Furthermore, there is a built-in moisture-proof and dust-proof cover at the emergency socket opening.

[0011] Furthermore, the area of each wire connected from the phase line and the neutral line on the main cable includes but is not limited to 2.5mm².

[0012] Compared with the prior art, the present utility model has at least one of the following beneficial effects:

[0013] The purpose of the present utility model is to provide a practical injection-molded branch compression joint with a power socket, adding a power socket to the injection-molded prefabricated branch cable compression joint to provide power when a line failure occurs in the branch distribution box and causes a power outage, for temporary lighting in the well, emergency use of electric tools, etc.

[0014] During the specific use process, an emergency socket is added to the traditional prefabricated branch cable. When there are multiple floors, it should be connected to the emergency power socket by staggering the phase for each floor (for example: the first floor - red and blue; the second floor - yellow and blue; the third floor - green and blue; the fourth floor - red and blue...).
