Abstract

A connector for joining two electrical connection assemblies including first and second assembly housings, each having a generally tubular wall open at one end. The first assembly housing has a cam. A collar is slidably attached to the exterior of the tubular wall of the second assembly housing. A moveable tab on one of the second assembly housing and the collar is in axial alignment with the cam of the first assembly housing. A stop ridge on the other of the second assembly housing and the collar is aligned with the tab so that the tab contacts the stop ridge at a predetermined point and restricts axial movement of the collar relative to the second assembly housing. Upon assembly of the first assembly housing and the second assembly housing, at a predetermined point of axial motion of the one with respect to the other, the cam of the first assembly housing pushes the moveable tab, disengaging the tab from the stop ridge, so that the collar is no longer so restricted, by contact of the tab and the stop ridge, from axial movement relative to the second assembly housing and the collar is thus permitted to move axially toward the first housing.

Claims

1. A connector for joining two electrical connection assemblies, comprising:

a first assembly housing having a generally tubular wall open at one end and a cam;

a second assembly housing having a generally tubular wall open at one end;

a collar, slidably attached to the exterior of the tubular wall of the second assembly housing;

a movable tab on one of the second assembly housing and the collar, the tab in axial alignment with the cam of the first assembly housing; and

a stop ridge on the other of the second assembly housing and the collar, the tab and the stop ridge aligned so that the tab contacts the stop ridge at a predetermined point, thus restricting axial movement of the collar relative to the second assembly housing;

wherein upon assembly of the first assembly housing and the second assembly housing, at a predetermined point of axial motion of the one with respect to the other, the cam of the first assembly housing pushes the movable tab, disengaging the tab from the stop ridge, so that the collar is no longer so restricted, by contact of the tab and the stop ridge, from axial movement relative to the second assembly housing and wherein the collar is permitted to move axially toward the first housing when the tab is disengaged from the stop ridge by the cam.

2. The connector of claim 1, further comprising,

a groove on one of the first housing and second housing;

and

at least one finger on the other of said first housing and second housing, the finger having a head;

wherein upon coupling, the head of the finger of the one housing fits within the groove of the other housing so that axial movement of the two housings with respect to each other in an uncoupling direction is resisted by the fit of the head of the finger within the groove.

3. The connector of claim 2 further comprising a plurality of fingers each having a head fitting in the groove of the outer housing.

4. The connector of claim 3 further comprising:

a plurality of cams on the first assembly housing;

a plurality of movable tabs on one of the second assembly housing and the collar, the tabs in axial alignment with the cams of the first assembly housing; and

a plurality of stop ridges on the other of the second assembly housing and the collar, -the tabs and the stop ridges aligned so that the tabs contact the stop ridges at a predetermined point, thus restricting axial movement of the collar relative to the second assembly housing;

wherein upon assembly of the first assembly housing and the second assembly housing, at a predetermined point of axial motion of the one with respect to the other, the cams of the first assembly housing push the movable tabs, disengaging the tabs from the stop ridges, so that the collar is no longer so restricted, by contact of the tabs and the stop ridges, from axial movement relative to the second assembly housing.

5. The connector of claim 2 wherein the collar is moveable between a first position and a second locking position such that the collar contacts the finger and holds the head of the finger within the groove in the second locking position.

6. The connector of claim 5 further comprising a head on the finger which extend radially outward from the generally tubular wall of the housing having the finger and further comprising a projection on the collar that contacts the radially outward extending head of the finger upon axial movement of the collar toward the open end of the second housing.

7. The connector of claim 6 further comprising an incline on the projection;

wherein the incline contacts the radially outward extending head of the finger upon axial movement of the collar toward the open end of the second housing.

8. The connector of claim 1, in which the cam has a ramp surface extending substantially from the coupling end of the tubular wall radially outward and rearward.

9. The connector of claim 1 further comprising:

a pair of at least partially circumferential grooves on the housing to which the collar is slidably attached; and

a sill on the collar selectively interlocked with each of the pair of at least partially circumferential grooves on the housing to which the collar is slidably attached.

10. A connector for joining two electrical connection assemblies, comprising:

a first assembly housing having a generally tubular wall open at one end and a plurality of cams;

a second assembly housing having a generally tubular wall open at one end;

a collar, slidably attached to the exterior of the tubular wall of the second assembly housing;

a plurality of resiliently movable tabs on one of the second assembly housing and the collar, the tabs arranged in axial alignment with the cams of the first assembly housing; and

a plurality of stop ridges on the other of the second assembly housing and the collar, the tabs and the stop ridges aligned so that the tabs contact the stop ridges at a predetermined point, thus restricting axial movement of the collar relative to the second assembly housing;

wherein upon assembly of the first assembly housing and the second assembly housing, at a predetermined point of axial motion of the one with respect to the other, the cams of the first assembly housing push the resiliently movable tabs, disengaging the tabs from the stop ridges, so that the collar is no longer so restricted, by contact of the tabs and the stop ridges, from axial movement relative to the second assembly housing; and

wherein upon disassembly of the first assembly housing and the second assembly housing, at a predetermined point of axial motion of the one with respect to the other, the cams of the first assembly housing disengage from the tabs, permitting the tabs to return by their own resiliency substantially to their initial position engaging their respective stop ridges, so that the collar is once again restricted, by contact of the tabs and the stop ridges, from axial movement relative to the second assembly housing.

11. The connector of claim 10, further comprising,

a groove on one of the first housing and second housing;

and

at least one finger on the other of said first housing and second housing, the finger having a head;

wherein upon coupling, the head of the finger of the one housing fits within the groove of the other housing so that axial movement of the two housings with respect to each other in an uncoupling direction is resisted by the fit of the head of the finger within the groove.

12. The connector of claim 11 further comprising a plurality of fingers each having a head fitting in the groove of the outer housing.

13. The connector of claim 12 further comprising heads on the fingers which extend radially outward from the generally tubular wall of the housing having the fingers.
