Connector

technical field

The utility model relates to the field of electrical connection accessories, in particular to a connector.

Background technique

A connector is a common electrical connection accessory used as an electrical connection medium between electronic devices. In the SMT (Surface Mount Technology, Surface Special Technology) production line, it is often necessary to use a large number of pin-seat connectors. However, this type of connector has a problem of processing difficulties in SMT automated production. The reason is that most of the manipulators used in SMT automated production are vacuum suction cup manipulators, and the needle seat connector does not have a flat adsorption. Due to the action of the manipulator on the surface, the manipulator often has the problem of grasping instability when grabbing the connector, which will eventually affect the soldering effect between the conductive terminal on the connector and the electronic circuit on the printed circuit board.
