The inspection of electronic connectors can be divided into pre-assembly inspection and post-assembly inspection

With the rapid development of intelligent equipment, connectors are widely used in various devices. They are a component frequently touched by electronic engineering and technical personnel, and are a bridge of communication in electronic circuits. Through the rapid, stable, low-loss and high-protection electrical signal Really transmit to ensure the normal performance of the complete functions of the device. Connector forms and structures are ever-changing. There are various types of connectors with different application objects, frequencies, power, and application environments. In order to improve its reliability, an inspection project will be carried out at the end of the production process of the connector to ensure product quality.

The connector is composed of a terminal plastic shell and a needle seat. Generally, it can be divided into pre-assembly and post-assembly inspections:

The inspection contents before assembly include: lack of material, burrs, shrinkage, deformation, chromatic aberration, dirt, plugging, indentation, unevenness/deformation of the barrier board, upturning of stuck points, sinking/deflection or breakage, and incorrect PIN identification / No PIN identification.

The inspection contents after assembly include: whether there is a gap between the copper shell/iron shell and the rubber shell, the iron shell/copper shell deformation, the buckle is not pressed in place/biased, the rubber shell is crushed, the left and right hooks are not installed in place (the two ends are stuck The exposed size of the hook is inconsistent), press the hook several times with your hand to confirm whether the left and right hooks are normal and whether there is elasticity.
