Abstract

A connection terminal for releaseably connecting a cable is disclosed having a terminal body, a contact arm, a cable fastening member, and a cable releasing member. The terminal body has a mating end and an opposite terminating end. The contact arm extends continuously from the mating end of the terminal body. The cable fastening member is positioned on the terminating end of the terminal body. The cable releasing member is positioned on the cable fastening member.

First claim

What is claimed is:

1. A connection terminal for releaseably connecting a cable, comprising:
a terminal body having a mating end and an opposite terminating end;
a contact arm extending continuously from the mating end of the terminal body, the contact arm having a free end having an arc structure and an angled, planar contact region positioned between the arc structure and the terminating end of the terminal body, the contact region contacting a mating connection terminal;
a cable fastening member positioned on the terminating end of the terminal body;
a cable releasing member positioned on the cable fastening member; and
a cantilevered arm extending obliquely from the cable fastening member along an insertion direction of the cable towards the terminal body, the cantilevered arm having a free end with a sharp edge that contacts the cable.

2. The connection terminal of claim 1 , wherein a cross-section of the terminal body and the cable fastening member on the terminating end is substantially U-shaped in a direction perpendicular to an insertion direction of the cable.

3. The connection terminal of claim 2 , wherein an opening of the U-shaped section defines the cable releasing member.

4. The connection terminal of claim 1 , wherein a conductor positioning member is positioned at a transition region between the cable fastening member and the terminal body, extending along the insertion direction.

5. The connection terminal of claim 1 , wherein the terminal body includes at least one holding projection positioned on each of two opposite sides of the terminal body.

6. The connection terminal of claim 1 , wherein a cable stop is positioned on the terminal body at a position distal to the cable fastening member and proximate to the contact arm, limiting an insertion length of the cable.

7. The connection terminal of claim 1 , wherein the terminal body further includes a terminal locking member extending from the terminal body towards the terminating end, opposite to the insertion direction.

8. A plug connector, comprising:
a housing having a terminal receiving passageway; and
a connection terminal disposed in the terminal receiving passageway for releasably contacting a cable, the connection terminal having
a terminal body having a mating end and an opposite terminating end,
a contact arm extending continuously from the mating end of the terminal body, the contact arm having a free end having an arc structure and an angled, planar contact region positioned between the arc structure and the terminating end of the terminal body, the contact region contacting a mating connection terminal,
a cable fastening member positioned on the terminating end of the terminal body,
a cable releasing member positioned on the cable fastening member, and
a cantilevered arm extending obliquely from the cable fastening member along an insertion direction of the cable towards the terminal body, the cantilevered arm having a free end with a sharp edge that contacts the cable.

9. The plug connector of claim 8 , wherein the housing has a locking member receiving hole extending from the terminal receiving passageway to an exterior of the housing in a thickness direction perpendicular to an insertion direction of the connection terminal.

10. The plug connector of claim 9 , wherein the terminal body further includes a terminal locking member extending from the terminal body towards the terminating end, opposite to the insertion direction.

11. The plug connector of claim 10 , wherein the terminal locking member is disposed in the locking member receiving hole.

12. The plug connector of claim 11 , wherein, when the terminal locking member is disposed in the locking member receiving hole, the connection terminal is prevented from moving in a direction opposite to the insertion direction.

13. The plug connector of claim 8 , wherein the housing has a terminal stopping protrusion disposed in the terminal receiving passageway.

14. The plug connector of claim 13 , wherein the connection terminal has a cable stop positioned on the terminal body at a position distal to the cable fastening member and proximate to the contact arm, limiting an insertion length of the cable.

15. The plug connector of claim 14 , wherein the cable stop abuts the terminal stopping protrusion, limiting an insertion of the connection terminal into the terminal receiving passageway along the insertion direction.

16. The plug connector of claim 8 , wherein the free end of the contact arm abuts against a first wall of the terminal receiving passageway.

17. The plug connector of claim 8 , wherein the housing has a guiding projection disposed in the terminal receiving passageway.

18. The plug connector of claim 17 , wherein the contact arm is positioned on the guiding projection.

19. The plug connector of claim 18 , wherein the housing has a stopping projection positioned on the guiding projection.

20. The plug connector of claim 19 , wherein the stopping projection blocks the free end of the contact arm.
