Claim 1

Independent Claim 219 words

A selectively applied lock member for maintaining the electrical connectors of first and second terminated electrical cables in full engagement and preventing their unwanted separation comprising: a) a base member having two parallel, spaced apart arms and a base aperture therebetween to accept a portion of the electrical connector of said first electrical cable; b) a lock member having a transverse member and two parallel, spaced apart locking arms, one extending from each of the two ends of said transverse member; the spacing between said locking arms being greater than the spacing between said base member arms and capable of accepting therebetween a portion of the electrical connector of said second electrical cable when the electrical connector of said second electrical cable is mated with the electrical connector of said first electrical cable in said base member; c) said lock member having a restricted entrance in said transverse member, said restricted entrance contoured to grip the second electrical cable around substantially more than 180 degrees of its periphery when said electrical connectors of said first and second electrical cables are mated, said restricted entrance providing strain relief for said second electrical cable; and d) coupling means coupling said lock member locking arms to said base member arms permitting relative rotational motion between said lock member and said base member.

Claim 2

Dependent Claim 219 words

A selectively applied lock member for maintaining the electrical connectors of first and second terminated electrical cables in full engagement and preventing their unwanted separation comprising: a) a base member having two parallel, spaced apart arms and a base aperture therebetween to accept a portion of the electrical connector of said first electrical cable; b) a lock member having a transverse member and two parallel, spaced apart locking arms, one extending from each of the two ends of said transverse member; the spacing between said locking arms being greater than the spacing between said base member arms and capable of accepting therebetween a portion of the electrical connector of said second electrical cable when the electrical connector of said second electrical cable is mated with the electrical connector of said first electrical cable in said base member; c) said lock member having a restricted entrance in said transverse member, said restricted entrance contoured to grip the second electrical cable around substantially more than 180 degrees of its periphery when said electrical connectors of said first and second electrical cables are mated, said restricted entrance providing strain relief for said second electrical cable; and d) coupling means coupling said lock member locking arms to said base member arms permitting relative rotational motion between said lock member and said base member.

Claim 3

Dependent Claim 84 words

A selectively applied lock member as defined in claim 1, wherein said coupling means comprises: a. two apertures, one in each of said two arms of said base member; and b. two pins, one on the inner surface of each of said locking arms of said lock member for mating engagement with their associated apertures in said arms of said base member whereby said base member and lock member may be rotated with respect to the other of said base member and lock member.

Claim 4

Dependent Claim 87 words

A selectively applied lock member as defined in claim 1, wherein said coupling means comprises: a. two apertures, one in each of said locking arms of said lock member; and b. two pins, one on the outer surface of each of said two arms of said base member for mating engagement with their associated apertures in said locking arms of said lock member whereby each of said base member and lock member may be rotated with respect to the other of said base member and lock member.

Claim 5

Dependent Claim 65 words

A selectively applied lock member as defined in claim 1, wherein said arms of said base member each have a stop along a marginal edge on the outer surface thereof; each of said stops being engaged by its associated locking arm to limit the rotation of said lock member with respect to said base member and said base member with respect to said lock member.

Claim 6

Dependent Claim 41 words

A selectively applied lock member as defined claim 4, wherein the rotation of said lock member with respect to said base member and the rotation of said base member with respect to said lock member is limited to 90° of rotation.

Claim 7

Dependent Claim 42 words

A selectively applied lock member as defined in claim 1, further comprising grip areas on the outer surface of said lock arms adjacent their juncture with said transverse member to facilitate rotation of said lock member with respect to said base member.

Claim 8

Dependent Claim 45 words

A selectively applied lock member as defined in claim 1, wherein said base member further comprises two mounting ears, one adjacent each end of said base member; said two mounting ears, each having an aperture therethrough to mount said base member upon a mounting surface.

Claim 9

Dependent Claim 99 words

A selectively applied lock member as defined in claim 7, further comprising: a. said base member having a front surface and a back surface; b. a recess in said back surface of said base member to receive the electrical connector of said first electrical cable and position the apertures in the mounting ears of such electrical connector in line with said apertures in the mounting ears of said base member to permit the fasteners used to mount said base member to a mounting surface to also fix said electrical connector of said first electrical cable to said base member.

Claim 10

Dependent Claim 75 words

A selectively applied lock member as defined in claim 1, further comprising: a. areas of reduced thickness at the free ends of said base arms; and b. a recess at the base of each locking arm adjacent its juncture with said transverse member each to receive the area of reduced thickness at the free end of its associated base arm for a portion of the rotational motion of said base member and said lock member.

Claim 11

Dependent Claim 37 words

A selectively applied lock member as defined in claim 9, wherein the free end of each of said base arms is arcuate and the recess at the base of each of said locking arms is complimentarily arcuate.

Claim 12

Dependent Claim 40 words

A selectively applied lock member as defined in claim 1, wherein said transverse member restricted entrance further comprises an electrical cable strain relief to help prevent damage to the connection between said second electrical cable and the connector connected thereto.

Claim 13

Dependent Claim 46 words

A selectively applied lock member as defined in claim 1, wherein said transverse member has a recess adjacent said restricted entrance; said recess defining two shoulders to engage the electrical connector connected to said second electrical cable to prevent its unwanted removal from said lock member.

Claim 14

Dependent Claim 55 words

A selectively applied lock member as defined in claim 11, wherein said second electrical cable has a built-up region adjacent its electrical connector and said electrical cable strain relief grips said built-up region of said second electrical cable to help prevent damage to the connection between said second electrical cable and the connector connected thereto.
