Abstract

The invention is directed to a crimp plug having a front portion, a center portion, and a securing portion. A conductor receiving cavity extends from the front e into the center portion. A stop shoulder within the center portion provides transition from the conductor receiving cavity to a plurality of conductor receiving passageway extending to a rear end. Each conductor receiving passageway serves to properly position the conductors while the stop shoulder serves to control the insertion length. A securing portion extends from the center portion and provides for securing of the cable.

Claims

1. A crimp plug for use in a connector comprising;

a front portion being insertable into the connector from a cable receiving end;

a mid portion having a conductor receiving cavity for receiving a plurality of conductors;

a stop shoulder disposed within the conductor receiving cavity of the mid portion; and

a securing portion extending from the mid portion opposite the front portion, the securing portion having a plurality of conductor receiving passageways extending from an end to at least one conductor receiving cavity of the mid portion.

2. The crimping plug of claim 1 further comprising a stop shoulder disposed at an end of the conductor receiving cavity.

3. The crimp plug of claim 1 wherein the front portion further comprises a projection disposed on an outer surface.

4. The crimp plug of claim 1 wherein the securing portion further comprises a ridge extending substantially around an outer surface of the securing portion.

5. The crimp plug of claim 4 further comprising a crimp ring disposed around the securing portion.

6. A crimp plug for use in a connector comprising;

a front portion being insertable into the connector from a cable receiving end;

a mid portion having a conductor receiving cavity for receiving a plurality of conductors; and

a securing portion extending from the mid portion opposite the front portion, the securing portion having a plurality of conductor receiving passageways extending from an end to at least one conductor receiving cavity of the mid portion; and

a stop shoulder disposed between the conductor receiving passageways and the conductor receiving cavity.

7. The crimp plug of claim 6 wherein each conductor receiving passageway is profiled to receive a single conductor and the conductor receiving cavity is profiled to receive a plurality of conductors.

8. A crimp plug for use in a connector comprising;

a front portion being insertable into the connector from a cable receiving end;

a mid portion having a conductor receiving cavity for receiving a plurality of conductors;

a securing portion extending from the mid portion opposite the front portion, the securing portion having a plurality of conductor receiving passageways extending from an end to at least one conductor receiving cavity of the mid portion; and

a crimp ring disposed around the securing portion, wherein a cable jacket is received between the crimp ring and the securing portion.

9. A crimp plug for use in a connector comprising;

a front portion being insertable into the connector from a cable receiving end;

a mid portion having a conductor receiving cavity for receiving a plurality of conductors;

a securing portion extending from the mid portion opposite the front portion, the securing portion having a plurality of conductor receiving passageways extending from an end to at least one conductor receiving-cavity of the mid portion; and

a crimp ring disposed around the securing portion, wherein a strength member is received between the crimp ring and the securing portion.

10. An optical connector comprising:

a housing having a cable receiving end for receiving a fiber from a cable;

a crimp plug having a securing portion and a conductor receiving passageway for receiving a portion of the cable, a center portion extending from the securing portion, and a front portion extending from the center portion, wherein said front portion has a conductor receiving cavity having a plurality of semicircular passageways extending from a front end toward the center portion.

11. The optical connector of claim 10 wherein the portion of the cable received on the securing portion is a cable jacket.

12. The optical connector of claim 10 wherein the portion of the cable received on the securing portion is a strength member.

13. The optical connector of claim 10 wherein the front portion further comprises a projection disposed on an outer surface.

14. The optical connector of claim 10 further comprising a plurality of conductor receiving passageways each for receiving a respective buffered fiber.

15. The optical connector as set forth in claim 10, wherein the front portion further comprises at least one securing projection disposed on an outer surface.

16. The optical connector as set forth in claim 10, wherein said securing portion further comprises at least one ridge extending substantially around an outer surface of the securing portion.

17. The optical connector as set forth in claim 10, wherein said securing portion is profiled to receive a crimp ring over the portion of said cable.

18. A crimp plug for use in a connector comprising;

a front portion being insertable into the connector from a cable receiving end, said front portion further comprising a plurality of semicircular passageways extending from a front end of said front portion toward the center portion;

a mid portion having a conductor receiving cavity for receiving a plurality of conductors;

a securing portion extending from the mid portion opposite the front portion, the securing portion having a plurality of conductor receiving passageways extending from an end to at least one conductor receiving cavity of the mid portion.

19. The optical connector of claim 18 wherein the conductor receiving cavity is profiled to receive a plurality of fibers from the conductor receiving passageway.
