Abstract

A locking assembly for releasably locking together a mating connector pair comprises a housing having a central aperture therethrough and adapted to be mounted to the first connector portion of the mating connector pair. A locking sleeve also having a central aperture is sized to receive the first connector portion and is also sized to be slidably received by the central aperture of the housing so that the locking sleeve can be rotated within the housing from a locked position to an unlocked position. The locking sleeve also includes a locking pin engaging boss for releasably engaging a locking pin associated with the second connector portion of the mating connector pair. Specifically, the locking pin engaging boss rotates the locking sleeve to the unlocked position as the first connector portion is engaged with the second connector portion. The locking pin engaging boss also allows the locking sleeve to be rotated to the locked position when the first and second connector portions are fully engaged. A biasing device associated with the locking sleeve biases the locking sleeve to the locked position.

Claims

1. A locking assembly for releasably locking together a mating connector pair, the mating connector pair including a first connector portion and a second connector portion, comprising:

a housing having a central aperture therethrough and a second aperture therethrough, said housing being adapted to be mounted to the first connector portion;

a locking sleeve having a central aperture therethrough sized to receive the first connector portion, said locking sleeve having a tab attached thereto wherein said tab extends through said housing second aperture, to manually rotate said locking sleeve said locking sleeve being adapted to be slidably received by the central aperture of said housing so that said locking sleeve can be rotated within said housing from a locked position to an unlocked position, said locking sleeve also including a locking pin engaging boss for releasably engaging a locking pin associated with the second connector portion, wherein said locking pin engaging boss rotates said locking sleeve to the unlocked position as the first connector portion is engaged with the second connector portion and allows the locking sleeve to be rotated to the locked position when the first and second connector portions are fully engaged; and

a biasing device associated with said locking sleeve for biasing said locking sleeve in the locked position.

2. The locking assembly of claim 1, further comprising an alignment sleeve adapted to be received by the central aperture of said locking sleeve so that said alignment sleeve is positioned between said locking sleeve and the first connector portion, said alignment sleeve including an indexing slot for engaging the locking pin on said second connector portion so that said alignment sleeve is maintained in a fixed radial alignment with respect to said second connector portion when the locking pin is engaged with said indexing slot, said alignment sleeve being secured within said housing so that said alignment sleeve cannot rotate with respect to said housing.

3. The locking assembly of claim 2, wherein said housing includes an alignment tab extending radially inward from the central aperture and wherein said alignment sleeve includes a slot sized to engage the alignment tab wherein said alignment sleeve is prevented from rotating with respect to said housing.

4. The locking assembly of claim 1, wherein the locking pin engaging boss of said locking sleeve extends generally radially inward from the central aperture in said locking sleeve, the locking pin engaging boss having a ramp section and a pin stop section, said ramp section being generally axially oriented with respect to the central aperture and said pin stop section being generally transversely oriented with respect to the central aperture.

5. The locking assembly of claim 1, wherein said biasing device comprises a spring.

6. The locking assembly of claim 1, wherein said biasing device comprises a V-shaped member having a first leg and a second leg, the first leg being attached to said locking sleeve, the second leg being retained by said housing.

7. The locking assembly of claim 1, wherein said first connector portion is mounted to a main connector body and wherein said housing is mounted to said main connector body.

8. The locking assembly of claim 7, wherein said main connector body includes a plurality of connector pins for transmitting supplemental electrical signals.

9. A push-lock connector assembly for releasably engaging a female BNC connector, comprising:

a male BNC center terminal; and

a locking assembly associated with said male BNC center terminal, said locking assembly including;

a housing having a central aperture therethrough and a second aperture therethrough, said housing being adapted to be mounted to said male BNC center terminal;

a locking sleeve having a central aperture therethrough sized to receive said male BNC center terminal, said locking sleeve having a tab attached thereto wherein said tab extends through said housing second aperture, to manually rotate said locking sleeve said locking sleeve being adapted to be slidably received by the central aperture of said housing so that said locking sleeve can be rotated within said housing from a locked position to an unlocked position, said locking sleeve also including a locking pin engaging boss for releasably engaging a locking pin associated with the female BNC connector, wherein said locking pin engaging boss rotates said locking sleeve to the unlocked position as said push-lock connector assembly is engaged with the female BNC connector and allows the locking sleeve to be rotated to the locked position when said male BNC center terminal and the female BNC connector are fully engaged; and

a biasing device associated with said locking sleeve for biasing said locking sleeve in the locked position.

10. The push-lock connector assembly of claim 9, further comprising an alignment sleeve adapted to be received by the central aperture of said locking sleeve so that said alignment sleeve is positioned between said locking sleeve and said male BNC center terminal, said alignment sleeve including and indexing slot for engaging the locking pin on the female BNC connector so that said alignment sleeve is maintained in a fixed radial alignment with respect to the female BNC connector when the locking pin is engaged with said indexing slot, said alignment sleeve being secured within said housing so that said alignment sleeve cannot rotate with respect to said housing.

11. The push-lock connector assembly of claim 10, wherein said housing includes an alignment tab extending radially inward from the central aperture and wherein said alignment sleeve includes a slot sized to engage the alignment tab wherein said alignment sleeve is prevented from rotating with respect to said housing.

12. The locking assembly of claim 9, wherein the locking pin engaging boss of said locking sleeve extends generally radially inward from the central aperture in said locking sleeve, the locking pin engaging boss having a ramp section and a pin stop section, said ramp section being generally axially oriented with respect to the central aperture and said pin stop section being generally transversely oriented with respect to the central aperture.

13. The push-lock connector assembly of claim 9, wherein said biasing device comprises a spring.
