[0002] Connectors are also called connectors. In China, they are also called joints and sockets, and generally refer to electrical connectors. That is, a device that connects two active devices to transmit current or signals. The male end and the female end can transmit information or current after contact, and are also called connectors; the basic performance of connectors can be divided into three categories: mechanical performance, electrical performance, and environmental performance. Another important mechanical performance is the mechanical life of the connector; with the development of technology, more and more fields need to use corresponding connectors, especially in certain specific fields, such as vehicle-mounted connectors. In order to meet more functions, multiple layers of multiple terminals need to be set in the connector.

[0003] The insulating body of the existing multi-layer multi-PIN connector is an integrally formed structure, and is processed by a mold and then an integral injection molding method. This processing method requires redesigning different injection molds according to the number of terminals to process different insulating bodies when processing connectors of different specifications. This not only makes the processing process more limited and can only process a single product, but also increases the processing cost; therefore, it is necessary to further improve the existing multi-layer multi-PIN connector structure.
