[0018] In order to enable those skilled in the art of this technology to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the scope of protection of this application.

[0019] Please refer to Figure 1-2 , a four-core plug crimping device for a wire braided rubber sheath connector, comprising a base 1, a jacket 2 fixedly connected to the base 1, a positioning seat 3 threadedly connected to the bottom of the jacket 2, the positioning seat 3 is installed in an inverted T shape, a return spring 4 is sleeved on the positioning seat 3, the upper end of the return spring 4 abuts against the bottom of the plug core 5, the plug core 5 slidably penetrates inside the jacket 2, a copper outer joint 6 is sleeved on the outer peripheral wall of the upper part of the plug core 5, a four-core plug 7 is penetrated through the inner wall of the copper outer joint 6, the four-core plug 7 is inserted into the plug core 5, a pressure sleeve 8 is pressed on the upper end of the four-core plug 7, and the lower end of the pressure sleeve 8 penetrates through the copper outer joint 6;

[0020] A positioning screw 9 is threadedly connected to the upper side wall of the outer sleeve 2, and the positioning screw 9 abuts against the outer wall of the copper outer joint 6;

[0021] A positioning screw 10 and a positioning screw 11 are threadedly connected to the lower side wall of the outer sleeve 2, and the positioning screw 10 and the positioning screw 11 abut against the outer wall of the plug core 5.

[0022] There is a shrinkage band in the middle of the inner wall of the outer sleeve 2. The diameter of the lower part of the plug core 5 is larger than that of the upper part of the plug core 5. The lower part of the plug core 5 is clamped below the shrinkage band, and the upper part of the plug core 5 slides through the inner wall of the shrinkage band; the positioning screw 10 and the positioning screw 11 are in the upper and lower positions. When the lower part of the plug core 5 is clamped under the shrinkage band, the positioning screw 10 abuts against the outer wall of the plug core 5. When the lower end face of the plug core 5 compresses the return spring 4 and abuts against the upper end of the positioning seat 3, the positioning screw 11 abuts against the outer wall of the plug core 5.

[0023] Use a press to accurately press the four-core plug 7 into the copper outer joint 6. This tooling ensures that after the copper outer joint 6 assembly is inserted into the tooling through the positioning screw 9 on the outer sleeve 2, it will not rotate randomly in the tooling, accurately limits the copper outer joint 6, and the outer diameter of the plug core 5 in this tooling is smaller than the inner hole size of the copper outer joint 6, so it can be easily inserted into the copper outer joint 6; then insert the four-core plug 7 into the plug core 5. The core of the plug core 5 is ensured not to rotate randomly through the positioning screw 10 and the positioning screw 11 on the outer sleeve 2. In this way, the relative position of the four-core plug 7 and the copper outer joint 6 can be accurately ensured. Then, the stroke of the plug core 5 is controlled by the adjustable positioning seat 3 to ensure that when the four-core plug 7 is pressed into the copper outer joint 6, the end face of the four-core plug 7 can be flush with the copper outer joint 6. When the pressing is completed and the press is released, the return spring 4 will restore the pressed joint assembly and the plug core 5 to the uncompressed state. After taking out the joint assembly, it is convenient for the next pressing.
