7 . The cap assembly for an electrical pass-through of claim 6 , wherein the cap guides are channels in the cap guide supports and the claw guides are radial extensions on the claw body.
8 . The cap assembly for an electrical pass-through of claim 1 , the cap portion including a claw catch that engages a claw lock on the claw portion when the cap portion is in the locked position to retain the claw portion in the locked position relative to the cap portion.
9 . The cap assembly for an electrical pass-through of claim 8 , wherein the claw catch is located on a lock tab that extends from the cap base and the claw lock is a radial extension on the claw body.
10 . An electrical pass-through comprising;
a housing with a cable opening that extends therethrough and defines a cable axis, and a cap lock; and
a cap assembly including a cap portion and a claw portion;
the cap portion including a cap base with a cap opening that extends therethrough and that the cable axis extends through;
a cap catch;
a plurality of lock surfaces that are angled relative to the cable axis such that as the distance from the claw portion increases, the distance between the lock surface and the cable axis decreases, and
a twist surface adjacent to the lock surface, wherein each twist surface extends substantially perpendicular from the respective lock surface and are angled at a twist angle relative to the cable axis; and
the claw portion including a claw body with a claw opening that the cable axis extends through, and
fingers that extend from the claw body towards the cap portion;
the cap portion movable relative to the claw portion from an initial position wherein the cap portion is separate from the claw portion, to a locked position wherein each of the fingers engages one of the lock surfaces and is deflected toward the cable axis and wherein each of the fingers engages one of the twist surfaces and is rotated relative to the claw base and wherein the cap lock engages the cap catch to retain the cap portion in position relative to the housing.
11 . The electrical pass-through of claim 10 , the cap portion including guide supports that extend from the cap base and include cap guides that extend parallel to the cable axis, and the claw portion including claw guides attached to the claw body, wherein in the locked position the claw guides engage the cap guides to prevent the cap portion from being rotated relative to the claw portion.
12 . The cap assembly of claim 11 , wherein the cap portion is movable relative to the claw portion from the initial position to a guide position wherein the claw guides engage the cap guides to prevent the cap portion from being rotated relative to the claw portion, and the cap portion is movable relative to the claw portion from the guide position to the locked position.
13 . The cap assembly of claim 12 , wherein the cap guides are channels in the cap guide supports and the claw guides are radial extensions on the claw body.
14 . The cap assembly of claim 12 , the cap portion including a claw catch that engages a claw lock on the claw portion when the cap portion is in the locked position to retain the claw portion in the locked position relative to the cap portion.
15 . The cap assembly of claim 14 , wherein the claw catch is located on a lock tab that extends from the cap base and the claw lock is a radial extension on the claw body.
16 . The cap assembly of claim 15 , wherein the cap guides are channels in the cap guide supports and the claw guides are radial extensions on the claw body.
17 . The cap assembly of claim 10 , the cap portion including a claw catch that engages a claw lock on the claw portion when the cap portion is in the locked position to retain the claw portion in the locked position relative to the cap portion.
