Abstract

The utility model discloses an elastic electric connection terminal including a pad, a bending part and a spring. The pad, the bending part and the spring are formed integrally. The front end of the spring is provided with a boss. The bending part connects with the pad and the spring respectively to make the pad and the spring be arranged oppositely. The electric connection terminal is characterized in that a protecting plate covers the spring from the outer side. At least one end of the protecting plate connects with the pad fixedly. According to the utility model, the protecting plate is arranged on the outer end of the spring of the elastic electric connection terminal. When in welding, a suction nozzle does not need to suck an upper end face of the spring, but sucks an upper end face of the protecting plate. Thus, poor welding phenomenon caused by the sinking and shaking of the spring is avoided, thereby improving the production quality of the elastic electric connection terminal. The utility model makes a great progress in elastic electric connection terminal technology.

Description

A kind of elasticity electric connection terminal

Technical field

The utility model relates to the electric connection terminal technical field, is specifically related to a kind of elasticity electric connection terminal.

Background technology

Summary of the invention

The technical problem that the utility model will solve provides a kind of elasticity electric connection terminal; The elasticity electric connection terminal that overcomes prior art is when welding; Suction nozzle is directly drawn the upper surface of elasticity electric connection terminal shell fragment, is prone to produce the defective of elasticity electric connection terminal failure welding.

The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:

A kind of elasticity electric connection terminal; The pad, bending part and the shell fragment that comprise one; The front end of said shell fragment is provided with convexity, and said bending part connects said pad and said shell fragment respectively, and said pad and said shell fragment are oppositely arranged; The outside at said shell fragment is covered with backplate, and at least one end of said backplate is fixedly connected with said pad.

Described elasticity electric connection terminal, wherein said backplate extends the back bending by a side of said pad and forms.

Described elasticity electric connection terminal, wherein said pad is provided with backplate movable end stopping means, and said backplate movable end stopping means can not produce relatively and the displacement of said pad said backplate movable end.

Described elasticity electric connection terminal, wherein said backplate movable end stopping means comprises horizontal card article above said backplate movable end, said card article is fixedly connected and is positioned at the supporting walls on the said pad.

Described elasticity electric connection terminal, wherein said card article is extended to form by said supporting walls.

Described elasticity electric connection terminal, wherein said supporting walls and said pad are wholely set.

Described elasticity electric connection terminal, wherein said backplate edge is provided with draw-in groove, and said card article embeds said draw-in groove.

The beneficial effect of the utility model: the utility model is provided with backplate in the outer end of elasticity electric connection terminal shell fragment; When welding; Suction nozzle need not be drawn the upper surface of shell fragment, but draws the upper surface of backplate, has so just avoided rocking because of the sinking of shell fragment the failure welding phenomenon of generation; Thereby improved the production quality of elasticity electric connection terminal, the utility model is a much progress of elasticity electric connection terminal technology.
