Abstract

An improved electrical connector and jack is provided. The electrical connector includes a main connector housing and a stereo plug protruding from a front surface of the main connector housing. A first pair of electrical contact pins is supported by the main connector housing on a first side of the stereo plug, and a second pair of electrical contact pins is supported by the main connector housing on a second side of the stereo plug opposite the first side of the stereo plug. An alignment feature protrudes from the front surface of the main connector housing adjacent the stereo plug, providing orientation key and anti-rotation functions to be provided with a narrower profile.

Claims

a stereo plug protruding from a front surface of the main connector housing;

a first pair of electrical contact pins supported by the main connector housing on a first side of the stereo plug; and

a second pair of electrical contact pins supported by the main connector housing on a second side of the stereo plug opposite the first side of the stereo plug.

2. The electrical connector of claim 1, and further comprising an alignment feature protruding from the front surface of the main connector housing.

3. The electrical connector of claim 2, wherein the alignment feature protrudes from the front surface of the main connector housing adjacent the stereo plug.

4. The electrical connector of claim 3, wherein the alignment feature further comprises an alignment key extending from the front surface in a direction away from the front surface which is substantially parallel to a longitudinal axis along which the stereo plug protrudes.

5. The electrical connector of claim 4, wherein the alignment key is positioned between the stereo plug and one of the first and second pairs of electrical contacts.

6. The electrical connector of claim 4, wherein the alignment key extends away from the stereo plug along a longitudinal direction of the front surface of the main connector housing.

7. The electrical connector of claim 6, wherein the stereo plug comprises:

a plurality of electrical contacts spaced apart along the longitudinal axis of the stereo plug; and

a plurality of insulators spaced apart along the longitudinal axis of the stereo plug, each of the plurality of insulators electrically separating adjacent ones of the plurality of electrical contacts.

8. The electrical connector of claim 7, wherein the alignment key is formed integrally with one of the plurality of electrical insulators of the stereo plug.

9. The electrical connector of claim 7, wherein the alignment key is formed integrally with one of the plurality of electrical contacts of the stereo plug.

10. The electrical connector of claim 2, wherein the main connector housing further comprises:

an upper pin housing, the upper pin housing having an outer surface and an inner surface, the outer surface forming a continuous surface with a surface of the main connector housing, the first pair of electrical contact pins being disposed along the inner surface of the upper housing;

a lower pin housing disposed in spaced-apart relation to the upper pin housing, the lower pin housing having an outer surface and an inner surface, the outer surface forming a continuous surface with the surface of the main connector housing, the inner surface facing the inner surface of the upper pin housing, the second pair of electrical contact pins being disposed along the inner surface of the lower pin housing; and

wherein the stereo plug protrudes from the front surface of the main connector housing between the inner surface of the lower pin housing and the inner surface of the upper pin housing.

11. The electrical connector of claim 10, wherein the electrical connector is adapted to connect to a jack, wherein the stereo plug is adapted to connectively insert into a plug port of the jack, and wherein the upper pin housing and the lower pin housing are adapted to connectively engage a forward plug port housing of the jack.

12. The electrical connector of claim 11, wherein the stereo plug includes a plurality of electrical contact pins for engaging a corresponding plurality of electrical contacts disposed along an interior surface of the plug port of the jack.
