Point crimping: This crimping method is mainly suitable for hole joints and crimping barrels with relatively thick walls. The cross-sectional shape after crimping can be seen, and it is pressed down from the top.
Because the wall thickness of this kind of terminal is relatively thick, the force of crimping is a little big, and the crimping cannot be realized with manual crimping pliers, and it can be realized with special hydraulic pliers, but the quality of crimping with hydraulic pliers is not high. And the efficiency is extremely low. The wire harness factory usually uses a special mold to realize the crimping on the punching machine, so that the crimping height can be precisely controlled, and the crimping quality and efficiency are better than hydraulic pliers.
This type of terminal is mainly used in the main circuit of the car and plays the role of transmitting power to the car circuit, so the requirements for crimping quality are relatively high.
