Abstract: A short type metal female terminal includes a base on which weld legs are disposed to provide an electrical connection with a light board. The base has an entrance through which a male terminal can pass. Two main elastic plates are respectively disposed at a left side and a right side of the base. The main elastic plates bend downwards and inwards, then extend oppositely to a place below the entrance, and then bend upwards to pass through the entrance. Thus, contact points of the main elastic plates opposite to each other are formed and located above the entrance. The male terminal passes between said contact points to carry out the electrical connection. The above structure is simple, and the electrical connection is more reliable.

The curved limiting part presses down on the conducting wire to prevent the wire from escaping. The elastic button is located above the funnel-shaped mouth. The elastic clips can be opened by pressing the elastic button which activates the funnel-shaped mouth.
