Abstract

A connector comprises a terminal member, an elastic member, and a housing having a cavity receiving the terminal member and the elastic member. The terminal member has a contacting face and a back face opposite to the contacting face. The contacting face has a serration region with a serration formed thereon and adapted to contact an electrical wire. The elastic member is adapted to press a pressed region of the back face opposite to the serration region.

First claim

What is claimed is:

1. A connector comprising:
a terminal member having a contacting face and a back face opposite to the contacting face, the contacting face having a serration region with a serration formed thereon, the serration region adapted to pierce an insulation film of an electrical wire;
an elastic member adapted to press a pressed region of the back face of the terminal member opposite to the serration region for applying a pressure on the electrical wire and making an electrical connection between the serration region and the electrical wire; and
a housing having a cavity receiving the terminal member and the elastic member.

2. The connector of claim 1 , wherein the terminal member has a press-fit portion press-fit into the cavity of the housing.

3. The connector of claim 2 , wherein the terminal member has a connecting portion forming an electrical connection with a terminal of a mating connector.

4. The connector of claim 1 , wherein the electrical wire is a coil winding positioned along a lower face of the housing defining the cavity.

5. The connector of claim 4 , wherein a distal end portion of the coil winding is wound around a columnar portion of the housing.

6. The connector of claim 1 , wherein the elastic member has an abutting portion with an abutting face adapted to abut against an inner wall face forming the cavity.

7. The connector of claim 6 , wherein the abutting portion receives a counterforce from the housing.

8. The connector of claim 7 , wherein the elastic member has a pressing portion folded back from the abutting portion and adapted to elastically press the pressed region.

9. The connector of claim 8 , wherein a distal free end portion of the pressing portion extends from a fixed end of the pressing portion at which the pressing portion is folded back from the abutting portion.

10. The connector of claim 9 , wherein, in a state in which the elastic member is disposed in the cavity and presses the terminal member, the distal free end portion abuts against a back face of the abutting portion, the back face of the abutting portion is opposite to the abutting face.

11. The connector of claim 10 , wherein the elastic member has a pair of pressing portions each folded back from the abutting portion and each adapted to elastically press the pressed region.

12. The connector of claim 10 , wherein the pressing portion is folded back from an end of the abutting portion in a direction of extension of the abutting portion.

13. The connector of claim 10 , wherein the pressing portion is folded back from a side face of the abutting portion.

14. A connector comprising:
a terminal member having a contacting face and a back face opposite to the contacting face, the contacting face having a serration region with a serration formed thereon and adapted to contact an electrical wire;
an elastic member adapted to press a pressed region of the back face of the terminal member opposite to the serration region for applying a pressure on the electrical wire; and
a housing having a cavity receiving the terminal member and the elastic member,
wherein the elastic member forms an electrical connection between the terminal member and the electrical wire and applies a greater pressing force to the terminal member as the electrical wire increases in diameter.

15. A connector comprising:
a housing defining a cavity;
an electrical wire arranged on a first interior face of the cavity;
a terminal member arranged within the cavity and having a contacting face abutting the electrical wire and a back face opposite the contacting face; and
an elastic member arranged within the cavity on a side of the terminal member opposite the electrical wire, the elastic member adapted to press on a region of the back face of the terminal member opposite to the contacting face in a direction of the first interior face of the cavity for applying a pressure on the electrical wire.

16. The connector of claim 15 , wherein the elastic member comprises:
an abutting portion abutting on a first side against a second interior face of the cavity, opposite the first interior face; and
a pressing portion folded back from the abutting portion and adapted to elastically press on the region of the back face of the terminal member opposite to the contacting face, wherein a distal free end portion of the pressing portion extends from a fixed end of the pressing portion at which the pressing portion is folded back from the abutting portion.

17. The connector of claim 16 , wherein, in a state in which the elastic member is disposed in the cavity and presses the terminal member, the distal free end portion abuts against a second side of the abutting portion, opposite the first side.

18. The connector of claim 16 , wherein an end portion of the electrical wire is fixedly connected to an exterior of the housing.

19. The connector of claim 16 , wherein the contacting face and back face of the terminal member are arranged proximate a first end of the terminal, wherein a second end of the terminal opposite the first end comprises a connecting portion configured to form an electrical connection with a corresponding terminal of a mating connector.
