Abstract
Description
Technical Field
[0001] This utility model relates to the field of integrated cable technology, and more specifically to an integrated cable branch box. Background Technology
[0002] DFW series high-voltage cable branch boxes are widely used for node connections in 10KV cable systems. They are the main electrical equipment for collecting and branching cables after they exit the switchgear. The cable joints of the branch boxes are tightly wrapped with high-grade insulated imported rubber, with no exposed live parts. The switches in branch boxes with switches are all SF6 insulated load switches.
[0003] Most integrated cable distribution boxes currently on the market have the following problems during use:
[0004] In practical use, traditional integrated cable distribution boxes contain a large number of cables. When these cables are connected, the ends of the cables tend to bend. As the number of cables increases, these bends can become damaged, exposing the internal wiring and reducing the lifespan of the cables. Furthermore, traditional integrated cable distribution boxes generate significant heat during operation. Their internal heat dissipation structures are ineffective and cannot effectively dissipate this heat, thus reducing their overall cooling performance. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an integrated cable branch box to solve the problems existing in the background art.
[0006] This utility model provides the following technical solution: an integrated cable branch box, including a branch box shell, with limiting blocks fixedly connected inside the branch box shell. The limiting blocks are symmetrically distributed and have slots inside. The branch box shell has a support plate inside, which is inserted into the slots. The support plate has clamping grooves inside, which are evenly distributed. The support plate can be embedded in the slots, thus fixing the support plate inside the branch box shell. The multiple clamping grooves can clamp the cables inside, providing support for the cable ends and preventing bending at the cable ends when connecting to the connection point, which could lead to damage at the bends, thereby increasing the cable's service life.
[0007] Furthermore, the inner wall of the branch box shell is provided with a support frame, and a limiting clip is fixedly connected inside the support frame. The limiting clip is connected to a heat sink by an inlay. When the branch box shell is in operation, it generates a large amount of heat. The heat sink inside can dissipate the heat generated inside in a timely manner, thereby improving heat dissipation.
[0008] Furthermore, a fixing hole is provided on the outside of the limiting block, and a fixing rod is connected to the inside of the fixing hole by insertion. The fixing rod is connected to the outside of the mounting block. When the support plate is embedded in the slot, the fixing rod is simultaneously inserted into the fixing hole. This can strengthen the embedded support plate and prevent the support plate from shaking or becoming unstable.
[0009] Furthermore, the fixing rod and fixing hole are symmetrically distributed, and the mounting block is attached to the outside of the limiting block. When the fixing rod is inserted into the inside of the fixing hole, the mounting block is simultaneously attached to the outside of the limiting block, which can play a blocking role.
[0010] Furthermore, the branch box housing has an internal connecting fixing block with an inner groove. The support frame has an external connecting magnetic block that is attached to the inside of the inner groove by adsorption. When the support frame is fixed to the inner wall of the fixing block, the magnetic block is simultaneously attached to the inside of the inner groove, which can reinforce the installed support frame.
[0011] Furthermore, the outer casing of the branch box is externally connected to a pivot, and the pivot is externally connected to a door. The door covers the outer casing of the branch box and is opened or closed via the pivot to facilitate operation of the internal integrated cables.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] 1. This utility model provides a limiting block and a support plate inside the branch box shell, and opens multiple clamping grooves inside the support plate. The support plate can be embedded in the grooves, so that the support plate is installed and fixed inside the branch box shell. The multiple clamping grooves can clamp the internal cables respectively, so as to support the tail end of the cable and avoid the phenomenon of bending of the cable tail end when the cable is connected to the connection point, which will cause damage at the bending point, thereby increasing the service life of the cable.
[0014] 2. This utility model has a support frame inside the branch box shell, and a heat sink inside the support frame. When the branch box shell is in operation, it generates a lot of heat. The heat sink inside can dissipate the heat generated inside in a timely manner, thereby improving heat dissipation. Attached Figure Description

In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] Reference Figure 1-6 This utility model provides an integrated cable branch box, including a branch box shell 1, with limiting blocks 5 fixedly connected inside the branch box shell 1. The limiting blocks 5 are symmetrically distributed, and slots 15 are opened inside the limiting blocks 5. A support plate 7 is provided inside the branch box shell 1. The support plate 7 is connected to the inside of the slots 15 by insertion. Clamping grooves 8 are opened inside the support plate 7 and are evenly distributed.
[0024] The support plate 7 can be embedded inside the slot 15, so that the support plate 7 will be installed and fixed inside the branch box housing 1. Multiple clamping slots 8 are provided to clamp the internal cables, so as to support the end of the cable and avoid the cable end from bending when connecting to the connection point, which would cause damage at the bend, thereby increasing the service life of the cable.
[0025] The inner wall of the branch box shell 1 is provided with a support frame 4. The support frame 4 is fixedly connected to a limiting clamp 11. The limiting clamp 11 is connected to a heat sink 10 by embedding. When the branch box shell 1 is in operation, it will generate a lot of heat. The heat sink 10 inside can dissipate the heat generated inside in time, thereby improving heat dissipation.
[0026] The limiting block 5 has a fixing hole 14 on its outside. The fixing hole 14 is connected to the fixing rod 13 by insertion. The fixing rod 13 is connected to the mounting block 9 on its outside. When the support plate 7 is embedded in the slot 15, the fixing rod 13 is simultaneously inserted into the fixing hole 14. This can strengthen the embedded support plate 7 and prevent the support plate 7 from shaking or becoming unstable.
[0027] The fixing rod 13 and the fixing hole 14 are symmetrically distributed. The mounting block 9 is attached to the outside of the limiting block 5. When the fixing rod 13 is inserted into the inside of the fixing hole 14, the mounting block 9 is simultaneously attached to the outside of the limiting block 5, which can play a blocking role.
[0028] The branch box shell 1 is internally connected to a fixing block 6, and the fixing block 6 has an inner groove 16. The support frame 4 is externally connected to a magnetic block 12, which is attached to the inside of the inner groove 16 by adsorption. When the support frame 4 is fixed to the inner wall of the fixing block 6, the magnetic block 12 is simultaneously adsorbed into the inside of the inner groove 16, which can strengthen the installed support frame 4.
[0029] The branch box housing 1 is externally connected to a rotating shaft 3, and the rotating shaft 3 is externally connected to a box door 2. The box door 2 covers the outside of the branch box housing 1, and the box door 2 is opened or closed via the rotating shaft 3 to facilitate operation of the integrated cables inside.
[0030] The working principle of this utility model is as follows: When using the integrated cable branch box, first place the branch box shell 1 in the desired position, then embed the support plate 7 inside the slot 15. In this way, the support plate 7 will be installed inside the branch box shell 1. Then, the fixing rod 13 is inserted into the fixing hole 14, which can strengthen the embedded support plate 7 and prevent the support plate 7 from shaking and becoming unstable. The mounting block 9 is attached to the outside of the limiting block 5, which can play a blocking role. Multiple clamping slots 8 are opened to clamp the internal cables respectively, so as to support the end of the cable and prevent the cable end from bending when connecting to the connection point. The bending point will cause damage, thereby increasing the service life of the cable. When the branch box shell 1 is in operation, it will generate a lot of heat. The internal heat sink 10 will operate to dissipate the heat generated inside in time, thereby improving heat dissipation.
