Abstract

An electrical connector (20) having a housing member has a latch (28 or 30) pivotably secured to the housing. The latch (28 or 30) has a latch arm (102) defining a plane and a cam arm (106). The latch (28 or 30) is pivotably actuable in the plane of the latch arm (102) upon applying a force to the cam arm (106) to rotate the latch (28 or 30) from a latched first position to an unlatched second position. The force is applied by moving a boot (38) axially along the connector housing through a limited distance from a forward position to a rearward position. Upon removal of the force from the cam arm (102), the cam arm (102) will return from the second position to the lower energy state of the first position due to the action of a spring (98). In returning to the first position, the cam arm (102) returns the boot to a forward position.

Claims

1. An electrical connector, comprising:

electrical contacts in at least one housing member, a shield over the housing member, an outer boot over the shield, at least one single piece latch with a unitary spring member, the latch being pivotally mounted to the shield, the boot being moveable rearwardly over the shield urging the latch pivotally to an unlatching position and biasing the unitary spring member, and the unitary spring member biasing the latch pivotally to a latching position wherein, a retention member is formed from the shield by which the unitary spring member is retained, and a distal end of the unitary spring member is received slidably in an aperture of the retention member.

2. An electrical connector as recited in claim 1, comprising:

a pivot formed from the shield to which the latch is pivotally mounted, and a retention member formed from the shield by which the unitary spring member is retained.

3. An electrical connector as recited in claim 1, comprising:

a forwardly located stop surface formed from the shield and engaging the boot, the boot being moveable forwardly over the shield to engage the stop surface.

4. An electrical connector as recited in claim 1, comprising:

a rearwardly located stop surface formed from the shield and engaging the boot, the boot being moveable rearwardly over the shield to engage the rearwardly located stop surface.

5. An electrical connector as recited in claim 1, comprising:

the latch being mounted laterally of the shield, and a laterally projecting protrusion on the shield positioned forwardly of the latch to prevent stubbing of the latch.

6. An electrical connector comprising:

electrical contacts in at least one housing member, at least one single piece latch with a unitary spring member, a latch mounting member on the housing member pivotally mounting the latch, the latch being moveable pivotally to an unlatching position and biasing the unitary spring member, and the unitary spring member biasing the latch pivotally to a latching position and the mounting member is a shield over the housing member, wherein, a retention member is formed from the shield by which the unitary spring member is retained, and a distal end of the unitary spring member is received slidably in an aperture of the retention member.

7. An electrical connector as recited in claim 6, comprising:

a pivot formed from the shield to which the latch is pivotally mounted, and a retention member formed from the shield by which the unitary spring member is retained.

8. An electrical connector as recited in claim 6, comprising:

the latch being mounted laterally of the shield, and a laterally projecting protrusion on the shield positioned forwardly of the latch to prevent stubbing of the latch.

9. An electrical connector, comprising:

electrical contacts in at least one housing member, a shield over the housing member, an outer boot over the shield, at least one single piece latch with a unitary spring member, the latch being pivotally mounted to the shield, the boot being moveable rearwardly over the shield urging the latch pivotally to an unlatching position and biasing the unitary spring member, the unitary spring member biasing the latch pivotally to a latching position, and both a pivot and a retention member formed from the shield, said pivot being by which the latch is pivotally mounted, and said retention member being by which the unitary spring member is retained.

10. An electrical connector as recited in claim 9, comprising:

the latch and unitary spring member being in the same plane and the latch arm being moveable pivotally in said plane.

11. An electrical connector, comprising:

electrical contacts in at least one housing member, a shield over the housing member, an outer boot over the shield, at least one single piece latch with a unitary spring member, the latch being pivotally mounted to the shield, the boot being moveable rearwardly over the shield urging the latch pivotally to an unlatching position and biasing the unitary spring member, the unitary spring member biasing the latch pivotally to a latching position, and a forwardly located stop surface formed from the shield and engaging the boot, the boot being moveable forwardly over the shield to engage the stop surface.

12. An electrical connector as recited in claim 11, comprising:

the latch and unitary spring member being in the same plane and the latch and being moveable pivotally in said plane.

13. An electrical connector, comprising:

electrical contacts in at least one housing member, a shield over the housing member, an outer boot over the shield, at least one single piece latch with a unitary spring member, the latch being pivotally mounted to the shield, the boot being moveable rearwardly over the shield urging the latch pivotally to an unlatching position and biasing the unitary spring member, the unitary spring member biasing the latch pivotally to a latching position, and a rearwardly located stop surface formed from the shield and engaging the boot, the boot being moveable rearwardly over the shield to engage the rearwardly located stop surface.

14. An electrical connector as recited in claim 13, comprising:

the latch and unitary spring member being in the same plane and the latch arm being moveable pivotally in said plane.

15. An electrical connector, comprising:

electrical contacts in at least one housing member, a shield over the housing member, an outer boot over the shield, at least one single piece latch with a unitary spring member, the latch being pivotally mounted to the shield, the boot being moveable rearwardly over the shield urging the latch pivotally to an unlatching position and biasing the unitary spring member, the unitary spring member biasing the latch pivotally to a latching position, the latch being mounted laterally of the shield, and a laterally projecting protrusion on the shield positioned forwardly of the latch to prevent stubbing of the latch.

16. An electrical connector as recited in claim 15, comprising:

the latch and unitary spring member being in the same plane and the latch arm being moveable pivotally in said plane.

17. An electrical connector comprising:

electrical contacts in at least one housing member, at least one single piece latch with a unitary spring member, a latch mounting member pivotally mounting the latch, the mounting member being a shield over the housing member, the latch being moveable pivotally to an unlatching position and biasing the unitary spring member, the unitary spring member biasing the latch pivotally to a latching position, and both a pivot and a retention member formed from the shield, said pivot being to which the latch is pivotally mounted, and said retention member being by which the unitary spring member is retained.
