Description

Technical Field

[0001] The utility model relates to a terminal box and belongs to the technical field of cable connection equipment. Background Art

[0002] The terminal box is a common device for cable connection, which can facilitate wiring and line checking, and thus facilitate line maintenance. During construction, the terminal box connects multiple branch lines through the wiring terminals installed in the terminal box. For example, the standardized PT terminal box disclosed in the patent application with announcement number CN220797738U includes a box shell, a cover plate, a lock, a terminal assembly, a through hole and a line fixing structure. By setting the line fixing structure, the line fixing structure is set on the upper and lower sides of the box shell, and a clamping plate assembly is set inside the line fixing structure. By rotating the clamping plate assembly screw assembly, the contraction and expansion between the front movable plate and the rear movable plate are controlled. The line is clamped and fixed by a rubber pad between the front movable plate and the rear movable plate, and the line connected to the terminal assembly is fixed and arranged, so that each line is neat and clear, so as to facilitate subsequent maintenance and power connection operations, and increase the connection stability of the line.

[0003] Since the cables themselves have a certain resistance, they will generate heat when they are powered. A single line may not generate much heat, but when multiple branch lines are connected together in a terminal box, the cables gathered together, especially at the inlet and outlet of the terminal box, are prone to heat accumulation, causing the line temperature to be too high, which in turn easily leads to aging and damage of the line insulation layer. In severe cases, it may even cause a circuit fire. Therefore, it is necessary to improve it to solve the above problems. Summary of the invention

[0004] The purpose of the utility model is to provide a terminal box that can effectively dissipate heat and avoid heat accumulation, thereby effectively slowing down line aging, so as to solve the problem that heat is easily accumulated in the existing terminal box, which easily causes line aging and even fire.

[0005] The technical solution of the utility model is:

[0006] A terminal box, which consists of a box body, a box cover and wiring terminals, the box body is provided with a box cover by a hinge, and a plurality of wiring terminals are arranged in the box body; the characteristic is that the outer end faces of the top and bottom of the box body are respectively provided with wire heat dissipation mechanisms, the wire heat dissipation mechanisms are composed of a wire plate, a pressure plate and heat dissipation fins arranged on the box body, the pressure plate is installed on the wire plate by fixing bolts, and the heat dissipation fins are evenly distributed on the pressure plate.

[0007] A plurality of wire grooves are arranged between the wire plate and the pressing plate, and the ports of the wire grooves extend into the box body.

[0008] The box body is provided with an assembly plate, which protrudes from the inner wall of the box body.

[0009] The assembly plate is evenly distributed with fixing bolt holes, and the wiring terminals are fixedly connected to the assembly plate through the fixing bolt holes and the fixing bolts.

[0010] The beneficial effects of the utility model are:

[0011] The terminal box can fix the cable between the conductor plate and the pressure plate. The pressure plate and the heat dissipation fins can quickly dissipate the heat from the cable, effectively reducing the surface temperature of the cable. At the same time, the conductor plate and the pressure plate can separate the cables to avoid cable aggregation.

[0018] The terminal box is composed of a box body 1, a box cover 2 and a wiring terminal 3. The box body 1 is provided with a box cover 2 by a hinge. A plurality of wiring terminals 3 are arranged in the box body 1, so that each branch line can be connected through the wiring terminals 3, which is convenient for wiring, line checking, and line maintenance. The box body 1 and the box cover 2 can protect the cables and the wiring terminals 3, and are dustproof and waterproof.

[0019] The top and bottom outer end faces of the box body 1 are respectively provided with wire heat dissipation mechanisms, so as to route the cables through the wire heat dissipation mechanisms to prevent the cables from gathering, thereby avoiding the heat generated by the cables from gathering, thereby effectively reducing the cable temperature; at the same time, the cables are cooled by the wire heat dissipation mechanisms to further reduce the cable temperature; by preventing heat accumulation and heat dissipation, the cable temperature can be effectively avoided from being too high, thereby effectively slowing down aging and avoiding electrical fires.

[0020] The wire heat dissipation mechanism is composed of a wire plate 4, a pressure plate 5 and heat dissipation fins 6 arranged on the box body 1. The pressure plate 5 is installed on the wire plate 4 by fixing bolts, so that the cable is restricted and fixed between the pressure plate 5 and the wire plate 4 through the pressure plate 5 and the wire plate 4, so as to route the cable, prevent the cable from gathering, and then prevent the heat generated by the cable from gathering, which can effectively reduce the cable temperature and effectively prevent the cable temperature from being too high; at the same time, it is convenient for wiring and checking the line; and the cable can be fixed by clamping the cable through the pressure plate 5 and the wire plate 4. Heat dissipation fins 6 are evenly distributed on the pressure plate 5, so that the contact area with the air is increased through the heat dissipation fins 6, thereby effectively increasing the heat dissipation area, so that the heat can be quickly dissipated, thereby further reducing the cable temperature and preventing the cable temperature from being too high.

[0021] A plurality of wire grooves 7 are arranged between the wire plate 4 and the pressing plate 5, and the ports of the wire grooves 7 extend into the box 1. The wire grooves 7 are used to limit and constrain the cables, thereby separating the cables, thereby facilitating wiring and tracing; and can prevent the cables from gathering, thereby preventing the heat generated by the cables from gathering, and effectively reducing the cable temperature; at the same time, the wire grooves 7 can effectively increase the contact area between the pressing plate 5 and the cables, which is conducive to the heat generated by the cables being conducted to the pressing plate 5, and then quickly dissipating the heat through the pressing plate 5 and the heat dissipation fins 6.

[0022] The box body 1 is provided with an assembly plate 8, which is protruding from the inner wall of the box body 1. The assembly plate 8 is evenly provided with fixing bolt holes 9, and the wiring terminals 3 are fixedly connected to the assembly plate 8 through the fixing bolt holes 9 and the fixing bolts. Since the fixing bolt holes 9 are evenly distributed on the assembly plate 8, when the wiring terminals 3 are assembled with the assembly plate 8 through the fixing bolt holes 9 and the fixing bolts, the wiring terminals 3 can be flexibly installed at any position of the assembly plate 8, so that the wiring terminals 3 and wiring can be arranged flexibly, reasonably and conveniently, and at the same time, the arrangement of the wiring terminals 3 and the wiring can be beautiful.

[0023] When the terminal box is connected to cables, the pressure plates 5 at the top and bottom of the box body 1 are removed respectively. After removing the pressure plates, insert the ends of each cable through the wire groove 7 into the box body 1, and connect the cable inserted from the top of the box body 1 with the cable inserted from the bottom of the box body 1 through the wiring terminal 3 in the box body 1. After the cables are connected and arranged, arrange the cables in the corresponding wire grooves 7 on the wire board 4, and arrange the cables. After the cable arrangement is completed, install the pressure plate 5 on the wire board 4 with the fixing bolts to clamp and fix the cables.

[0024] The terminal box can fix the cable between the conductor plate 4 and the pressure plate 5. The pressure plate 5 cooperates with the heat dissipation fins 6 to quickly dissipate the heat of the cable, effectively reducing the surface temperature of the cable. At the same time, the conductor plate 4 and the pressure plate 5 can separate the cables to avoid cable aggregation. By separating the cables, heat accumulation can be effectively avoided, and the surface temperature of the cables can be further effectively reduced. By reducing the cable temperature, the aging of the cable insulation layer can be effectively slowed down, and fire can be effectively avoided. The wiring terminals 3 can be fixed at any position of the assembly plate 8 through the evenly distributed fixing bolt holes 9. The wiring terminals 3 can be arranged reasonably and beautifully, and wiring can be convenient. The problem that heat is easily accumulated in the existing terminal box, which can easily cause line aging and even cause fire is solved.
