Connector and insertion core assembly thereof

Abstract

The invention relates to a connector and an insertion core assembly thereof. The insertion core assembly comprises an insulator, an insulation pressing plate and a metal end cover which are sequentially arranged in a front-back direction; the insulation pressing plate is fixedly arranged on the front side surface of the metal end cover so as to form a mounting base body; the insulator is fixedly arranged on the mounting base body; front power terminal holes and rear power terminal holes are correspondingly matched with each other and provided with power terminals in a limiting manner; front signal terminal holes and rear signal terminal holes are correspondingly matched with each other and provided with signal terminals in a limiting manner; a front grounding terminal hole and a rear grounding terminal hole are correspondingly matched with each other and provided with a grounding terminal in a limiting manner; the grounding terminal is conductively connected with the metal end cover; and corresponding wire passing holes for allowing power cables electrically connected with the power terminals and signal cables in signal connection with the signal terminals to pass are formed in themetal end cover. With the connector and the insertion core assembly thereof of the invention adopted, the insulation pressing plate, the insulator and the metal end cover can be relatively fixed after being assembled; and the insulator, the insulation pressing plate and the metal end cover can be fixedly assembled without a rear cover required.

Description

technical field [0001] The invention relates to a connector and ferrule assembly thereof. Background technique [0002] The power exchange connector includes a plug connector arranged on the battery pack side and a socket connector arranged on the body side of the electric vehicle. When the plug connector and the socket connector are mated, the plug terminal and the socket terminal are mated to realize electrical connection. [0003] The receptacle connector includes a metal barrel, an insulating pressing plate, an insulator, and a pressing cover. In the prior art, the insulating pressure plate and the insulator are sequentially assembled in the metal cylinder, and then the gland and the metal cylinder are matched by fasteners to be press-fitted on the insulator, thereby realizing the assembly of the socket connector. However, the above-mentioned socket connector is not fixed before the gland is fastened, and the insulating pressure plate and the insulator are not fixed. It...

AI Technical Summary

Problems solved by technology

However, the above-mentioned socket connector is not fixed before the gland is fastened, and the insulating pressure plate and the insulator are not fixed. It is not easy to determine the installation position of the insulating pressure plate and the insulator before pressing through the pressure plate. When the pressure plate is pressed, it is necessary to readjust the metal cylinder, The relative position of the insulating pressure plate and the insulator, the labor intensity of the workers is relatively high
