The locking connector is composed of three parts of a contact piece, an insulator and a shell (according to varieties). The contact (contabs) is the core component of the connector that performs the electrical connection function. Generally, a contact pair is composed of a male contact and a female contact, and the electrical connection is completed by inserting the female and male contacts. The male contact is a rigid part and is in the shape of a cylinder (round pin), a square cylinder (square pin) or a flat shape (insert). The male contact is typically made of brass, phosphor bronze. The female contact piece, namely the jack, is a key part of the contact pair and is in tight contact with the male contact piece by generating elastic force through elastic deformation when the elastic structure is inserted into the contact pin so as to complete connection. The structure of the jack is various, and there are cylinder type (split slot, necking), tuning fork type, cantilever beam type (longitudinal slot), folding type, box type (square jack), hyperboloid wire spring jack, etc. The connector fixing structure includes several guide columns vertically set below the connector body and inserted into the jacks in the circuit board to position the connector body.
