Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a connector with a double-row pin terminal assembly. Background Art

[0002] In the field of automotive connectors, automotive parts are electrically connected through electrical connectors and integrated in a compact and sealed space. The electrical connector includes an insulating shell and conductive terminals installed on the insulating shell. One end of the insulating shell holds and accommodates the conductive terminals for plugging into other connectors, and the other end extends out of the insulating shell for fixing to the device.

[0003] The male and female ends of existing electrical connectors can only be identified through color recognition, logo recognition, software recognition and other feature recognition methods to prevent mistakes. When two or more connectors of the same specification and model are used, it is very likely that male and female ends that are not originally paired can be plugged in normally, resulting in an incorrect electrical connection, which may cause serious safety hazards. In addition, the connector connection is unstable in a vibrating environment, and communication is interrupted during use, affecting the performance of the connector.

[0004] Connectors generally refer to electrical connectors, that is, devices that connect two active devices, transmit current or signals, and the male and female ends can transmit information or current after contact. Among them, connectors play the role of connection and conduction. Different manufacturers have different requirements for energy storage connectors. In general, they develop towards miniaturization and easy operation. Among connectors, elbow plug-in type is the representative, which can solve the problem of small space and easy operation.

[0005] A connector is usually considered to be a component attached to a cable or installed on an instrument. As a component that electrically connects or separates a transmission line, it is a mechatronics product. Simply put, it mainly plays a bridging role. Connectors can be divided into plug-in connectors and threaded connectors according to the connection method. The connecting sleeve shell and the connecting head shell on the existing plug-in connector do not have a fixed limiting structure, and are connected by a simple plug-in and pull-out method. When connecting the connecting sleeve shell and the connecting head shell, one end of the connecting head shell is generally inserted into one end of the connecting sleeve shell. When people accidentally pull the wire on the connector, the connecting sleeve shell and the connecting head shell are easily disconnected, thereby affecting people's normal use of the connector, and the stability of the connector connection is poor.
