Abstract

A contact includes a body section, a tail section arranged at a lower portion of the body section, a peg extending from the tail section such that the peg projects from a front surface of the contact, and a fusible member attached to the contact such that the peg protrudes into the fusible member. A lower portion of the fusible member is offset from a main portion of the fusible member.

First claim

What is claimed is:

1. A contact comprising:
a body section;
a tail section arranged at a lower portion of the body section;
a peg extending from the tail section such that the peg projects from a front surface of the contact; and
a fusible member attached to the contact such that the peg protrudes into the fusible member; wherein
a lower portion of the fusible member is offset from a main portion of the fusible member; and
a lowermost surface of the lower portion of the fusible member is located below a lowermost surface of the contact.

2. The contact according to claim 1 , further comprising a slot in the tail section that is adjacent to the peg.

3. The contact according to claim 1 , wherein the peg widens with increasing distance from the front surface of the contact.

4. A contact comprising:
a body section;
a tail section arranged at a lower portion of the body section;
a peg extending from the tail section such that the peg projects from a front surface of the contact; and
a fusible member attached to the contact such that the peg protrudes into the fusible member; wherein
a lower portion of the fusible member is offset from a main portion of the fusible member; and
a plane defined by the front surface of the contact intersects the lower portion of the fusible member.

5. A contact comprising:
a body section;
a tail section arranged at a lower portion of the body section;
a peg extending from the tail section such that the peg projects from a front surface of the contact; and
a fusible member attached to the contact such that the peg protrudes into the fusible member; wherein
a lower portion of the fusible member is offset from a main portion of the fusible member; and
at least a portion of a lowermost surface of the lower portion of the fusible member extends below a lowermost surface of the contact.

6. A connector system comprising:
a substrate; and
a connector connected to the substrate and including a contact; wherein
the contact includes:
a body section;
a tail section arranged at a lower portion of the body section;
a peg extending from the tail section such that the peg projects from a front surface of the contact; and
a fusible member attached to the contact such that the peg protrudes into the fusible member; wherein
a lower portion of the fusible member is offset from a main portion of the fusible member; and
a lowermost surface of the lower portion of the fusible member is located below a lowermost surface of the contact.

7. A contact comprising:
a body section;
a tail section arranged at a lower portion of the body section;
a peg extending from a front surface of the body section or a front surface of a middle portion of the tail section spaced away from an end of the tail section; and
a fusible member attached to the contact; wherein
the peg protrudes into the fusible member;
the tail section is angled with respect to the body section; and
the front surface of the tail section is coplanar or approximately coplanar with the body section.

8. The contact according to claim 7 , wherein the tail section has a curved shape.

9. The contact according to claim 7 , wherein:
the tail section includes a hole; and
the fusible member is arranged to at least partially extend into the hole.

10. The contact according to claim 7 , wherein at least one notch is located in the peg and engages with the fusible member.

11. A connector system comprising:
a substrate; and
a connector connected to the substrate and including a contact; wherein
the contact includes:
a body section;
a tail section arranged at a lower portion of the body section;
a peg extending from a front surface of the body section or a front surface of a middle portion of the tail section spaced away from an end of the tail section; and
a fusible member attached to the contact; wherein the peg protrudes into the fusible member;
the tail section is angled with respect to the body section; and
the front surface of the tail section is coplanar or approximately coplanar with the body section.
