Abstract

A butterfly spring connector made from a one-piece blank is disclosed. comprising a The butterfly spring connector includes:
a frame, comprising a first, second and third frame pieces defining a bottom plane; a butterfly spring comprising the connection of an upper piece, a lower piece and a lateral piece, wherein the lateral piece extends from the first frame piece to a direction perpendicular to the bottom plane; a support formed at the third frame piece to support the lower piece; and a clip piece formed at the second frame piece, to clip a wire or a cable in association with the upper piece.

The support and the clipping piece extend in the same direction of the lateral piece.

First claim

What is claimed is:

1. A butterfly spring connector, comprising:
a one-piece element that includes a frame, a butterfly spring, a support, and a clamp section all integrally formed from the same piece of metal:
said frame comprising a first frame section and second and third frame sections respectively connected to each end of the first frame section; the first, second and third frame sections defining a bottom plane;
said butterfly spring comprising an upper section, a lower section and a lateral section, wherein the upper section and the lower section connect to form an acute angle, the lower section and the lateral section connect to form an angle, and the lateral section extends in a direction perpendicular to the bottom plane and includes at least a partial edge connected to the first frame section;
said support formed at the third frame section to support the lower section of the butterfly spring when the upper section of the butterfly spring deforms due to an external force; and
said clamp section formed at the second frame section, to clamp a wire or a cable in association with the upper piece of the butterfly spring;
wherein the support and the clamp section extend in the same perpendicular direction of extension from the bottom plane as the lateral section.

2. The butterfly spring connector of claim 1 , wherein the frame further includes a plate disposed at the bottom plane defined by the first, second and third frame sections.

3. The butterfly spring connector of claim 1 , wherein an opening is formed at the second frame section at a position corresponding to an end of the upper section.

4. The butterfly spring connector of claim 1 , wherein the upper or lower section of the butterfly spring further comprises at least one bent projection towards an interior of the angle formed by the upper and lower sections.

5. The butterfly spring connector of claim 1 , wherein the upper or lower section of the butterfly spring further comprises at least one bent projection extending towards an exterior of the angle formed by the upper and lower sections.

6. The butterfly spring connector of claim 1 , wherein a slot is formed at connection of the lateral section and the first frame section, to adjust a stiffness of the butterfly spring.

7. The butterfly spring connector of claim 1 , further comprising at least one connector pin extended from one of the frame sections.

8. The butterfly spring connector of claim 1 , wherein the butterfly spring connector is formed by a metal plate.

9. The butterfly spring connector of claim 1 , further comprising a contact piece extended to form a connector clip with two connector pins, a main body of the contact piece being plugged into the space between the upper section of the butterfly spring and the second frame section.
