Background Connectors are important devices for electrical connection, and are mainly used for transmitting power or electrical signals. Clip-type terminal connectors are generally used when the connector is connected to a PCB. In order to adapt to the connection with the PCB boards with different thicknesses, the terminal is generally changed into a bent terminal to be electrically connected with the PCB board (this is described in the mating information, and the bent terminal is the basis, if it is not the bent terminal, the housing space of the housing is not necessarily enlarged). However, when the terminal is changed into a curved structure, the accommodating space of the housing should be correspondingly enlarged to accommodate the terminal, and the problem of insufficient pre-tightening of the housing to the terminal inevitably occurs due to the enlarged accommodating space.
