Technical Field
The utility model relates to a detect frock technical field, especially indicate a circuit board card contact pin detects frock.
Background
Signal transmission is needed between the internal or input/output interfaces of the instrument and the circuit board card, and an electric connector is inevitably used. A common electrical connector consists of a fixed end, i.e. a female contact (shortly called socket), and a free end, i.e. a male contact (shortly called plug). The socket and the plug are respectively fixed on the two circuit board cards in a screw fixing or welding mode, and the metal contact pins at the plug end are in contact with the metal reeds in the end holes of the socket to form electrical connection. An electrical connector can generally transmit multiple sets of electrical signals, for example, a 96-core european connector can transmit 96-channel signals, i.e., a header has 96 pins.
In the links of transferring, welding, debugging and using, if improper operation occurs, under the action of stress, bending of the contact pin can be caused with a certain probability. Especially, after the socket and the board card are welded, the bending of the contact pin can lead to the fact that the plug cannot be smoothly inserted into the socket, and the bending of the contact pin can lead to the short circuit with the adjacent contact pin in serious cases, which causes the wrong electrical connection of the contact pin or the adjacent contact pin, and further possibly leads to the electrical function fault of the circuit board card and even the circuit damage. Therefore, after the welding in the production process of the equipment is completed and before the power-on debugging, whether the contact pin of the electric connector of each circuit board card is bent or not is detected, and whether the contact pin of the electric connector which can be plugged and pulled by a user is bent or not is necessary when the equipment leaves a factory.
