Description

Technical Field

[0001] The utility model relates to the technical field of distribution box production and manufacturing, and more specifically, to an exposed cable protection device for a distribution box of an electrical engineering. Background Art

[0002] The function of the distribution box is to distribute and control power to electrical equipment. When the circuit is overloaded, short-circuited, or leaking, the distribution box can also provide power-off protection. The cables connected to the distribution box will extend from the outside of the distribution box to the inside to connect to the electrical structure of the equipment inside the distribution box. In order to ensure safe use, the exposed cable part of the distribution box needs to be protected;

[0003] When the cable is pulled by external force, it is easy to be pulled directly off the wiring terminals inside the box. In addition, the wire holes of many distribution boxes are on the back of the box. When a single worker is performing wiring work, it is difficult for the worker to fix the wire end after inserting it into the wire hole. When the worker goes around to the front of the box, the cable often slips out of the box through the wire hole, affecting the wiring efficiency.

[0004] The utility model with Chinese patent application number CN202120547182.X discloses a device for protecting exposed cables in a distribution box of an electrical engineering project, comprising a cylinder with an opening at the upper end, the cylinder is fixedly mounted on the wall of the distribution box, the opening of the cylinder is connected to the inner cavity of the distribution box, a first through hole is provided on the bottom surface of the cylinder, a sleeve with openings at both ends is slidably fitted inside the cylinder, a spring is fixedly connected between the bottom surface of the sleeve and the bottom surface of the inner cavity of the cylinder, and several inclined plates are fixedly mounted on the top surface of the sleeve, and the upper ends of the inclined plates are all away from each other and expand outward. The utility model utilizes a simple spring and claw structure to achieve reliable fixation of the cable on the one hand, and can provide a short elastic stroke buffer when the cable is pulled by external force, thereby protecting the cable to the maximum extent. The clamping and loosening states of the device can be switched by a key-like push rod, and the cable will not be affected from being fed into the distribution box in the clamped state, which can greatly improve the operation efficiency during wiring. It is a new type of cable protection device that is easy to operate, simple and reliable in structure;

[0005] Then, combined with the drawings in the instruction manual, it can be seen that by pulling the claws with the spring, the cable can only move into the distribution box, which is convenient for installation, connection and use. However, after the connection, the part of the cable extending out of the pipe is still exposed to the outside, and there is a gap between the cable and the pipe, which makes it inconvenient to protect and the protection effect is poor.
