Spring connection technology

　　In order to solve the above problems, the present invention provides a spring connector, which includes a spring, a metal cover for placing the spring, and a metal connector covered on the metal cover; the spring comprising a main body part and an extension part bent outward from the lower end of the main body part, the metal cover comprises a bottom wall and a side wall extending from the bottom wall to the direction of the metal connecting piece, the metal cover The connecting member is covered with the side wall, the extension portion of the spring is in contact with the bottom wall of the metal cover, and the main body portion of the spring passes through the metal connecting member.

　　Preferably, the extension portion is arranged around the main body portion.

　　Preferably, the extension part is further fitted with the side wall of the metal cover.

　　Preferably, the extension part and the metal cover are fixed by spot tin.

　　Preferably, the metal connecting piece includes a bottom plate that is covered with the side wall, a sleeve portion extending from the bottom plate in a direction away from the metal cover, and an end portion extending outward along the periphery of the bottom plate, The main body portion of the spring protrudes from the metal connecting member from the sleeve portion.

　　Preferably, the metal cover is provided with a snap portion protruding inward from the upper end surface of the side wall and arranged at intervals, the chassis includes a notch portion corresponding to the snap portion, and the snap portion is snapped together the chassis.

　　Preferably, the metal cover and the metal connecting member are fixed by laser spot welding.

　　The beneficial effects of the utility model are: the spring connector provided by the utility model can be directly installed/injected into the basin frame of the sounding unit as a standard component for electrical contact, and there will be no spring skew and electrical failure caused by false welding and pollution. Contact instability problem.
