Abstract
A wiring terminal provided by the utility model comprises a male terminal and a female terminal. The male terminal has a front end for connection and conduction. The female terminal has a contact spring used for clamping the front end. The wiring terminal is characterized in that the wiring terminal also comprises a composite housing used for supporting the contact spring, and a sheath used for fixing the composite housing, the contact spring is installed in the composite housing, the composite housing is positioned in the sheath, the composite housing is provided with a jack used for the contacting of the contact spring with the front end, a side wall of the composite housing adjacent to the jack is provided with an inverted hook for stopping, the inverted hook comprises a bonding portion contacted with the contact spring and a bending hook formed by extending and bending along the bonding portion, and the bonding portion abuts against the contact spring. Since the bonding portion abuts against the contact spring, when the male terminal and the female terminal are jointed, the mechanical strength of the contact spring can be enhanced, the yield deformation is not easy to occur, and the connection of the male terminal and the female terminal are more stable.
