Description

Technical Field

In the existing public literature, the Chinese patent publication number CN108767618A discloses a power cable terminal extrusion connection device and its connection processing technology. The extrusion connection device can solve the problems that the existing cable terminals cannot be fixed to the cable terminal frame when connected to the cable, the fixed position of the terminal frame cannot be adjusted, the extrusion position of the pressure column on the terminal is deviated, the pressure column on the terminal will drive the terminal to move when it is squeezed, and the terminal cannot be corrected after its position is squeezed. However, the extrusion connection device still has the following problems during use:

[0003] When the extrusion connection equipment is performing extrusion connection on the power cable and the terminal, since the power cable core is basically circular and is inserted into the circular hole inside the terminal, the extrusion is achieved through parallel pressure, which will cause the circular hole inside the terminal and the power cable core to be over-tightened in the middle and easily break, while the edges will be extruded too lightly, resulting in a certain gap and unstable connection.
