[0025] The discharge groove 16 is composed of two inclined grooves, and the discharge groove 16 is connected with the right angle position of the slide groove 6. In mechanical processing, the discharge groove 16 is treated as ninety degrees. Because when the actual milling machine is chamfering in the processing process, if the discharge groove 16 is composed of a right angle, it will cause installation interference between the wire pressing block 7 and the connecting block 5. Therefore, the discharge groove 16 is composed of two inclined grooves. In mechanical processing, the discharge groove 16 is treated as ninety degrees.

[0026] The utility model is provided with a wire pressing block 7, which is moved downward by the telescopic end of the hydraulic cylinder 4, so that the crimping terminal 14 on the soft copper stranded wire 9 is pressed to form a required arc surface. When the wire pressing block 7 is manufactured, the arc surface needs to be opened by wire cutting, and when the arc surface of the wire pressing block 7 is pressed against the upper surface of the crimping terminal 14, the arc surface of the crimping terminal 14 after pressing is the required bending angle. Therefore, by pressing the crimping terminal 14 on the soft copper stranded wire 9 by the wire pressing block 7, it is possible to avoid using a manually operated bending machine for bending, thereby reducing manual labor.

After the small tube terminal 15 is crimped, the small tube terminal 15 and the crimping terminal 14 are tightly connected and have a beautiful appearance.

[0031] Furthermore, considering that the flat-mounted crimping terminal 14 is located in the middle area of ​​the connecting terminal 10, when the flat-mounted crimping terminal 14 is used, since the crimping terminal 14 is in a suspended state, it is easy for the upper surface of the crimping terminal 14 to bend and cause damage. Therefore, an arc surface is provided at the bottom of the crimping block 7, and a sliding groove is provided inside the fixed guide block 8 as a flat surface. When the crimping block 7 presses the crimping terminal 14, the upper surface of the crimping terminal 14 is an arc surface and the lower surface is a flat surface, so that the crimping terminal 14 is in contact with the connection position during connection and is not in a suspended state.
