Abstract

A pin contact for an electrical connector is disclosed having a contact body and a pin. The contact body is formed from a metal sheet and has a mating end, a pin receiving space and an offset wall. The pin receiving space extends inward from the mating end. The offset wall has at least one welding region, and an outer surface facing away from the welding region and accessible from the outside. The pin is positioned in the pin receiving space and projects out of the mating end. The pin is welded to the welding region.

First claim

What is claimed is:

1. A pin contact for an electrical connector comprising:
a contact body formed from a metal sheet and having
a mating end,
a pin receiving space extending inward from the mating end,
an offset wall having at least one welding region and an outer surface facing away from the welding region and accessible through a tool receiving channel extending linearly from the outer surface to outside the contact body, and
an overlapping inner wall and an outer wall, both walls positioned on a side of the contact body, the outer wall having at least one cantilevered arm; and

a pin positioned in the pin receiving space and projecting out of the mating end, and being welded to the welding region.

2. The pin contact of claim 1 , wherein the welding region of the offset wall extends a distance into the pin receiving space.

3. The pin contact of claim 1 , wherein the offset wall is formed from a portion of the inner wall.

4. The pin contact of claim 3 , wherein the inner wall and the outer wall are formed from opposite end sections of the metal sheet.

5. The pin contact of claim 1 , wherein the outer wall is spaced apart from the inner wall.

6. The pin contact of claim 1 , wherein the tool receiving channel is positioned proximate to the cantilevered arm.

7. The pin contact of claim 1 , wherein the cantilevered arm is positioned at the level of the welding region, extending along a longitudinal axis.

8. The pin contact of claim 1 , wherein an end section of the outer wall forms a reinforcing bridge extending substantially parallel to the cantilevered arm.

9. The pin contact of claim 8 , wherein the reinforcing bridge partially surrounds the tool receiving channel.

10. The pin contact of claim 9 , wherein the reinforcing bridge has a ridge on an inner surface, the ridge defining a first portion of the tool receiving channel.

11. The pin contact of claim 10 , wherein the reinforcing bridge further comprises a recess defining a second portion of the tool receiving channel.

12. The pin contact of claim 11 , wherein the ridge and the recess taken together, define the tool receiving channel.

13. A pin contact for an electrical connector comprising:
a contact body formed from a metal sheet and having
a mating end,
a pin receiving space extending inward from the mating end,
an offset wall having at least one welding region and an outer surface facing away from the welding region and accessible from the outside, and
an overlapping inner wall and an outer wall, both walls positioned on a side of the contact body, the outer wall having at least one cantilevered arm; and

a pin positioned in the pin receiving space, projecting out of the mating end, welded to the welding region, and having an offset portion extending toward and contacting the offset wall.

14. A pin contact for an electrical connector comprising:
a contact body formed from a metal sheet and having
a mating end,
a pin receiving space extending inward from the mating end,
an offset wall having at least one welding region and an outer surface facing away from the welding region and accessible from the outside, and
an overlapping inner wall and an outer wall, both walls positioned on a side of the contact body, the outer wall having at least one cantilevered arm; and

a pin having at least one widened portion positioned in the pin receiving space, the pin projecting out of the mating end and being welded to the welding region.
