Description

A fixed wire clamp used in a distribution box

technical field

The invention belongs to the field of distribution box wiring tools, and in particular relates to a fixed wire clip used in a distribution box.

Background technique

With the continuous development of the times, the distribution box has become a common working tool. When the distribution box is used, a large number of cables are required. The traditional processing method of these cables is to fix and limit them by wrapping tape to prevent They are placed at will with the free extension angle. The disadvantage of fixing with tape is that if one of the cables needs to be replaced or a new cable is added, it is very inconvenient to destroy the original tape and re-sort and sort. In order to overcome the above-mentioned defects, the existing patent titled "A Cable Fixing Clamp", the patent document with the publication number 201120115289.3 has disclosed a fixing clamp, which can effectively solve the problem of using adhesive tape or fixing points. However, this kind of fixed clamp still has certain limitations, because the number of cables in the distribution box is different and the position of the interface is different, which leads to different ways of cable distribution (sometimes arranged circumferentially, Sometimes they are arranged side by side), and the space where the cables are located is also different. The above-mentioned fixed clamps can only fix the wires arranged side by side. If the cables in the distribution box are distributed along the circumferential direction, the space where the cables are located is similar to a cylindrical cavity. In this case, the above-mentioned fixed clamps cannot be used, and the distance between the cables in the distribution box is relatively close, which will cause the temperature of the cables to rise during long-term work. When the temperature reaches a critical point, the cables will spontaneously ignite , If it cannot be found in time in a small space, there will be a greater potential safety hazard, and in order to deal with the occurrence of the above situation, it is of great practical significance to develop a fixed wire clip used in a distribution box.

working principle

When using the present invention, the space where the cable is located must first be specified. If the computers involved are arranged along the circumference, the lines are generally arranged in a cylindrical space. If the computers involved are arranged along the Arranged in a straight line, the lines are generally arranged in a relatively long and narrow space. The different installation spaces of the cables determine the final form of the present invention in use, which is to arrange N clamp units along the circumferential direction to form a ring or an arc. Shaped wire clips (as shown in Figure 1), or N wire clamp units are staggered in the forward and reverse directions to form a wave shape (as shown in Figure 2), it is up to the operator to decide according to the actual situation, two adjacent wire clamp units are combined , first insert the connecting cylinder 2 of the first wire clamp unit into the No. 1 blind hole 11 in the second wire clamp unit, and at the same time pull the locking pin 41 in the second wire clamp unit and make its end part of the No. 1 blind hole 11, the cylinder 2 to be connected is completely inserted into the No. 1 blind hole 11, the locking pin 41 is released to make it rebound under the action of the return spring 42, and the end of the locking pin 41 moves along the two No. 1 blind hole 12 moves and is inserted into No. 1 through hole 21 at the same time to realize the connection between the first wire clamp unit and the second wire clamp unit.
