Description

Technical Field

[0001] The utility model belongs to the technical field of grounding boxes, and particularly relates to a grounding box capable of preventing cables from falling off. Background Art

[0002] The grounding box is used to store and protect the grounding wires. It shares the same function as the grounding busbar, serving as a connection device for the grounding wires. There are three types of grounding boxes: direct grounding box, protective grounding box, three-phase cross-connected grounding box, and three-phase six-wire grounding box.

[0003] At present, in the existing technology, a terminal block is set in the grounding box to connect with the cable and is tightened by bolts. The installation firmness is poor. During actual use, if the cable is accidentally pulled, it is very easy to cause the cable to loosen or even fall off from the terminal block (terminal block).

[0004] Therefore, in order to solve the above problems, it is necessary to design a grounding box that prevents cables from falling off. Utility Model Content

[0005] The utility model aims to provide a grounding box which can prevent cables from falling off, so as to solve the technical problem that the connection between the existing grounding box and the cable is easy to fall off.

[0006] In order to solve the above technical problems, the utility model provides a grounding box for preventing cable from falling off, comprising:

[0007] The box body has a plurality of wiring sockets arranged therein;

[0008] Several anti-drop components corresponding to the wiring seat, including: a support rod arranged on the inner wall of the box and a spring sleeved on the outside of the support rod;

[0009] A plurality of wiring tubes corresponding to the wiring seats, which are connected to the box body;

[0010] The spring is adapted to support the cable between the wiring tube and the wiring seat, so that when the cable is pulled, the spring is compressed and extends out of the wiring tube.

[0011] Furthermore, the anti-slip assembly further comprises: a special-shaped piece sleeved on the support rod;

[0012] The special-shaped member is slidably connected to the support rod; and

[0013] The bottom of the special-shaped part is connected with the spring.

[0014] Furthermore, the special-shaped part includes: a collar portion and a rod portion; wherein

[0015] The collar portion is sleeved on the support rod;

[0016] The anti-slip assembly further comprises: a guide wheel sleeved on the rod;

[0017] The guide wheel is rotatably connected to the rod; and

[0018] The guide wheel is suitable for supporting the cable between the wiring tube and the wiring seat.

[0019] Furthermore, a guide portion is provided on the support rod;

[0020] The collar portion is provided with a raised portion; wherein

[0021] The protrusion is suitable for sliding up and down in the guide portion.

[0022] Furthermore, the wiring seat is provided with wiring holes and bolt holes;

[0023] The wiring hole and the bolt hole are arranged vertically and connected to each other;

[0024] A bolt is provided in the bolt hole; wherein

[0025] The bolt is adapted to compress the cable inserted into the wiring hole when engaged with the bolt hole.

[0026] The beneficial effects of the utility model are:

[0027] (1) The utility model inserts one end of the cable into the wiring hole after passing it through the wiring tube and resting it on the guide wheel, and tightens the cable when the bolt engages with the bolt hole. When the cable is pulled, the cable presses down the guide wheel, and the guide wheel slides on the support rod through the special-shaped part and compresses the spring. At this time, the cable continues to extend outward. Through the above steps, the effect of preventing the cable from separating from the wiring seat after being pulled is achieved.
