[0001] The utility model relates to the technical field of pre-branching cables, and more specifically, to a pre-branching cable which is easy to repair. Background Art

[0002] Pre-branching cable is a cable with a special structure, which is mainly used for branching and distributing power lines. Its composition structure usually includes main cable, branch cable, connector, and insulating protective tube. During the installation of the insulating protective tube, special sealant usually needs to be injected at the cable port, and multiple screws need to be tightened for installation. Disassembly and assembly are inconvenient. When the connector or terminal becomes loose, has poor contact, is damaged, or other joint failures occur during use and need to be repaired, the insulating protective tube often needs to be disassembled and reinstalled after the maintenance is completed, which makes the maintenance more time-consuming and labor-intensive. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a pre-branching cable that is easy to maintain, so as to solve the problem that during the installation of the insulating protective tube, special sealant usually needs to be injected at the cable port, and multiple screws need to be tightened for installation, which makes disassembly and assembly inconvenient and leads to time-consuming and labor-intensive maintenance.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a pre-branching cable that is easy to maintain, comprising a pre-branching cable main body, an insulating box is arranged at the branch of the pre-branching cable main body, a switch round frame is rotatably connected inside the insulating box, the left and right sides of the switch round frame and the front and rear sides of the insulating box are hollow structures, the front and rear sides of the switch round frame are closed structures, and a round frame fixing component for fixing the switch round frame is arranged on the top of the insulating box.

[0005] Among them, the insulating box is formed by two half box bodies spliced ​​together by a number of screws, and the half box body is arranged on the outer surface of the branch of the pre-branching cable body through a sealing rubber sleeve. The switch round frame is formed by two semi-circular frames spliced ​​together, and the semi-circular frame can slide along the slide rail inside the half box body.

[0006] Wherein, the insulating box also includes a sealing strip arranged on the half box body, and the sealing strip is used to improve the sealing effect between the semicircular frame and the half box body.

[0007] Wherein, the switch circular frame also includes friction patterns arranged on the semicircular frame, and the friction patterns are used to increase friction force to facilitate the rotation of the semicircular frame.

[0008] Wherein, the semicircular frame is made of transparent material.

[0009] Among them, the circular frame fixing component includes a telescopic rod, two L-shaped insertion frames and several springs. One end of the L-shaped insertion frame is connected to the semi-box body through the telescopic rod, and the other end penetrates through the semi-box body and is movably inserted into the top of the semi-circular frame. The middle of the L-shaped insertion frame is connected to the semi-box body through a spring. The two L-shaped insertion frames can be inserted into each other to form a 冂-shaped insertion frame.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] With the settings of the semi-box body and the semi-circular frame in the present utility model, when maintenance is required, the maintenance personnel can rotate the semi-circular frame by friction through the friction lines, so that the semi-circular frame rotates along the inside of the semi-box body, align the hollow side with the hollow side of the semi-box body, and then the branch of the pre-branched cable main body can be maintained. With the above structure, when it is necessary to maintain the branch of the pre-branched cable, the insulating box can be opened more conveniently without complicated disassembly and assembly operations, saving time and effort and improving the maintenance efficiency.

[0012] With the settings of the telescopic rod, the L-shaped insertion frame and the spring, after the two semi-box bodies, the two semi-circular frames and the two L-shaped insertion frames are spliced and installed together, lift the 冂-shaped insertion frame. At this time, the telescopic rod extends and the spring stretches, and the L-shaped insertion frame is pulled out from the top of the semi-circular frame to release the fixation of the semi-circular frame. On the contrary, through the contraction of the spring, the L-shaped insertion frame can be automatically inserted into the semi-circular frame again to fix the semi-circular frame. With the above structure, through the spliced L-shaped insertion frame, the fixation of the two semi-circular frames can be fixed or released at the same time, and when the two semi-box bodies and the semi-circular frames are not spliced together, the semi-box body and the semi-circular frame can be relatively fixed, so as to facilitate their assembly, improving the installation efficiency and practicability.

[0019] To make the technical problems, technical solutions and advantages to be solved by the present utility model clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] As shown in the attached Figure 1 to the attached Figure 4 An embodiment of the present utility model provides a pre-branched cable convenient for maintenance, including a pre-branched cable main body 1. An insulating box 2 is arranged at the branching part of the pre-branched cable main body 1. A switch circular frame 3 is rotatably connected inside the insulating box 2. The left and right sides and the front and back sides of the switch circular frame 3 are all hollow structures. The front and back sides of the switch circular frame 3 are closed structures. A circular frame fixing component 4 for fixing the switch circular frame 3 is arranged at the top of the insulating box 2;

[0021] Specifically, rotating the switch circular frame 3 by 90° can open the front and back of the insulating box 2, so as to facilitate the maintenance of the branching part of the pre-branched cable main body 1.

[0022] Among them, the insulating box 2 is formed by splicing two half-box bodies 21 through a plurality of screws, and the half-box body 21 is sleeved on the outer surface of the branching part of the pre-branched cable main body 1 through a sealing rubber sleeve. The switch circular frame 3 is formed by splicing two semi-circular frames 31, and the semi-circular frame 31 can slide along the slide rail inside the half-box body 21.

[0023] Among them, the insulating box 2 further includes a sealing strip 22 arranged on the half-box body 21. The sealing strip 22 is used to improve the sealing effect between the semi-circular frame 31 and the half-box body 21.

[0024] Among them, the switch circular frame 3 further includes friction lines 32 arranged on the semi-circular frame 31. The friction lines 32 are used to increase the friction force and facilitate the rotation of the semi-circular frame 31.

[0025] Among them, the semi-circular frame 31 is made of a transparent material. Through the setting of the semi-circular frame 31, the situation of the connection of the branched cable can be roughly seen without disassembly, so as to facilitate a simple judgment of the fault situation of the branched cable.

[0026] Among them, the circular frame fixing component 4 includes a telescopic rod 41, two L-shaped plug frames 42 and a plurality of springs 43. One end of the L-shaped plug frame 42 is connected to the half-box body 21 through the telescopic rod 41, and the other end penetrates through the half-box body 21 and is movably inserted into the top of the semi-circular frame 31. The middle part of the L-shaped plug frame 42 is connected to the half-box body 21 through the spring 43. The two L-shaped plug frames 42 can be inserted into each other to form a U-shaped plug frame;

[0027] Specifically, through the setting of the spring 43, the telescopic rod 41 is kept contracted without external force, so that the L-shaped plug frame 42 can keep the semi-circular frame 31 plugged and fixed.

[0028] The working process of the present utility model is as follows:

[0029] When maintenance is needed, the maintenance personnel rotate the semicircular frame 31 by friction with the friction pattern 32, so that the semicircular frame 31 rotates along the half box body 21, aligns the hollow side with the hollow side of the half box body 21, and then performs maintenance on the branch of the pre-branching cable body 1;

[0030] After the two half boxes 21, the two semicircular frames 31 and the two L-shaped racks 42 are assembled together, the L-shaped racks are lifted. At this time, the telescopic rod 41 is extended and the spring 43 is stretched, and the L-shaped racks 42 are pulled out from the top of the semicircular frames 31 to release the fixation of the semicircular frames 31. Conversely, the spring 43 contracts and the L-shaped racks 42 can be automatically reinserted into the semicircular frames 31 to fix the semicircular frames 31.
