Abstract

A backshell assembly that includes a housing configured to terminate a cable. The housing has a main body defining a central longitudinal axis, a connector interface for mating with an electrical connector, and at least one adjustment extension extending from the main body opposite the connector interface and substantially parallel to the central longitudinal axis. An adjustable strain relief structure is coupleable to the cable and the housing. The adjustable strain relief structure including at least one adjustment member cooperating with the adjustment extension of the housing such that the adjustment member is pivotable between different cable positions with respect to the central longitudinal axis of the housing. A movable locking member is coupleable with the adjustment extension of the housing and the adjustment member of the adjustable strain relief structure to releasably lock the adjustment member in a selected cable position with respect to the housing. A biasing member is supported by the locking member. The biasing member biasing the locking member into engagement with the adjustment extension of the housing and the adjustment member. The biasing member allows adjustment of the adjustment member between the different cable positions with respect to the adjustment extension of the housing without disassembly of the housing and the adjustable strain relief structure.

wherein said biasing member allows adjustment of said adjustment member between said different cable positions with respect to said adjustment extension of said housing without disassembly of said housing and said adjustable strain relief structure.

2. A backshell assembly according to claim 1, wherein

said biasing member is a spring.

3. A backshell assembly according to claim 1, wherein

said adjustment member defining an axis, and said different cable positions of said adjustment member with respect to said central longitudinal axis of said housing being defined by an angle between said axis of said adjustment member and said central longitudinal axis of said housing.

4. A backshell assembly according to claim 1, wherein

said adjustment member is an arm having an opening at a distal end thereof that receives said biasing member.

5. A backshell assembly according to claim 1, further comprising:

at least one cable clamp coupled to an end of said adjustment member for clamping the cable.

6. A backshell assembly according to claim 1, wherein

said adjustable strain relief structure includes a second adjustment member pivotable with respect to second adjustment extension of said housing;

and

a second movable locking member engages said second adjustment member and said second adjustment extension.

7. A backshell assembly according to claim 1, wherein

said locking member engages corresponding openings in said adjustment extension and said adjustment member.

8. A backshell assembly according to claim 7, wherein

9. A backshell assembly according to claim 7, wherein

each of said corresponding openings in said adjustment extension and said adjustment member includes gear teeth;

said gear teeth of said openings of said adjustment extension and said adjustment member being adapted to engage gear teeth of said locking member.

10. A backshell assembly according to claim 9, wherein

said adjustment member defining an axis, and said different cable positions of said adjustment member with respect to said central longitudinal axis of said housing being defined by an angle between said axis of said adjustment member and said central longitudinal axis of said housing;

and

said angles of said different cable positions corresponding to said gear teeth of said adjustment extension and said locking member.

11. A backshell assembly according to claim 1, wherein

said locking member includes an actuator for moving said locking member into and out of engagement with said adjustment extension and said adjustment member.

12. A backshell assembly according to claim 11, wherein

said actuator supports said biasing member and extends through corresponding openings of said adjustment extension and said adjustment member.

13. A backshell assembly according to claim 12, wherein

said actuator is a fastener coupled to a spline of said locking member.

14. A backshell assembly, comprising of:

a housing configured to terminate a cable, said housing having a main body defining a central longitudinal axis, and a connector interface for mating with an electrical connector;

an adjustment member coupleable to the cable and said housing such that said adjustment member is pivotable between different cable positions with respect to said central longitudinal axis of said housing, said adjustment member including an opening having gear teeth;

a movable locking member coupleable with said housing and said adjustment member to releasably lock said adjustment member in a selected cable position with respect to said housing, said movable locking member including gear teeth corresponding to the gear teeth of said adjustment member; and
