Abstract

A connector having a hermaphroditic contact is disclosed. Such hermaphroditic contact extends longitudinally and is formed as a unitary body from a conductive material. The contact has a base residing in a plane and extending longitudinally and traversely in the plane, a blade arm extending longitudinally from the base and generally in the plane of the base, and a spring arm extending longitudinally from the base alongside the blade arm. The spring arm is springingly displaceable toward at least a first side of the plane of the base. To electrically couple first and second generally identical ones of the contact, the bases of the first and second contacts are aligned to be co-planar, and the blade arm of the each contact is aligned to face toward the spring arm of the other contact. The first and second contacts are then moved together such that the blade arm of each contact encounters the spring arm of the other contact. Thereafter, the first and second contacts are further moved together such that the blade arm of each contact displaces the spring arm of the other contact toward the first side of the plane of the base of the other contact.

a first portion relatively close to the intermediate portion;

a second portion farther away from the intermediate portion than the first portion and generally residing in the plane of the intermediate portion; and

4. The contact of claim 3 wherein the first portion of the spring arm generally resides on the first side of the plane of the intermediate portion, the first portion thereby defining a blade arm acceptance region adjacent thereto and generally in the plane of the intermediate portion.

5. The contact of claim 4 wherein the first portion of the spring arm has a proximal end curving toward the intermediate portion and a distal end curving toward the second portion.

6. The contact of claim 1 mounted to a floor of a connector, the blade arm and the spring arm both extending longitudinally and generally perpendicularly with respect to the floor of the connector, the floor of the connector defining a well adjacent the blade arm on a second side of the plane of the intermediate portion opposite the first side, wherein when the contact is electrically coupled to a generally identical corresponding contact, the well accommodates the spring arm of the corresponding contact.

7. A longitudinally extending hermaphroditic contact formed as a generally unitary body from a conductive material and comprising:

an intermediate portion defining a plane;

a mounting portion extending from the intermediate portion in a first direction, the mounting portion being generally co-planar with the intermediate portion; and

a mating portion extending from the intermediate portion in a second direction generally opposite the first direction, the mating portion having;

a blade generally coplanar with the intermediate portion; and

a spring arm adjacent the blade and residing at least partially outside the plane of the intermediate portion.

8. The contact of claim 7 wherein the blade and the spring arm are laterally arranged and both extend from the intermediate portion in one general longitudinal direction.

9. The contact of claim 7 wherein the spring arm has:

a first portion relatively close to the intermediate portion;

a second portion farther away from the intermediate portion than the first portion and generally residing in the plane of the intermediate portion; and

a third portion farther away from the intermediate portion than the second portion and generally residing on a first side of the plane of the intermediate portion, the third portion generally extending away from the second portion and toward such first side.

10. The contact of claim 9 wherein the first portion of the spring arm generally resides on the first side of the plane of the intermediate portion, the first portion thereby defining a blade arm acceptance region adjacent thereto and generally in the plane of the intermediate portion.

11. The contact of claim 10 wherein the first portion of the spring arm has a proximal end curving toward the intermediate portion and a distal end curving toward the second portion.

12. The contact of claim 7 mounted to a floor of a connector, the blade and the spring arm both extending longitudinally and generally perpendicularly with respect to the floor of the connector, the floor of the connector defining a well adjacent the blade arm, wherein when the contact is electrically coupled to a generally identical corresponding contact, the well accommodates the spring arm of the corresponding contact.

13. A longitudinally extending hermaphroditic contact formed as a generally unitary body from a conductive material and comprising:

an intermediate portion having generally opposing edges and defining a plane;

a mounting portion extending from one of the edges of the intermediate portion; and

a bifurcated mating portion extending from the other of the edges of the intermediate portion, the mating portion having;

a blade extending generally parallel to the plane of the intermediate portion; and
