Description

Technical Field

[0001] The present invention relates to a connector terminal and a connector including the connector terminal. Background Art

[0002] In the prior art, the connector in the charging gun or charging seat usually includes a shell and a terminal installed in the shell. The terminal usually includes a terminal body and an elastic member inserted in the terminal body. The elastic member is used to make electrical contact with the mating terminal inserted into the terminal body. In the prior art, in order to position the elastic member in the terminal body, a first axially opposite positioning protrusion and a second positioning protrusion are usually formed on the inner circumferential surface of the terminal body. The first positioning protrusion and the second positioning protrusion are suitable for respectively abutting against the two ends of the elastic member to axially position the elastic member. However, in order to allow the elastic member to be elastically deformed, the axial spacing between the first positioning protrusion and the second positioning protrusion is usually slightly larger than the distance between the two end faces of the elastic member, so that the elastic member can move axially in the terminal body. This causes the elastic member to be at risk of detaching from the terminal body, especially when the mating terminal is inserted at an angle, it is easy to cause the elastic member to detach from the terminal body.
