Abstract

A separable clasp connector is provided that has first and second parts that are pivotable with respect to one another by a die set. The clasp connector includes one or more die alignment features to ensure proper alignment with the die set so as to apply an unlocking force in a predetermined direction. Die sets and methods also provided to move a separable clasp connector back-and-forth among a locked position and an unlocked position.

First claim

What is claimed is:

1. A separable clasp connector, comprising:
a first part having a first connector body and a first connector barrel, the first connector barrel being configured to secure the first part to a first electrical conductor; and
a second part having a second connector body and a second connector barrel, the second connector barrel being configured to secure the second part to a second electrical conductor,
the first connector body having a first blade, a first blade slot, a first cam slot defined in the first blade, and a first pin in the first cam slot, the first pin extending above a mating surface of the first blade
the second connector body having a second blade, a second blade slot, a second cam slot defined in the second blade, and a second pin in the second cam slot, the second pin extending above a mating surface of the second blade,
the first and second connector bodies being connectable to allow movement of the first and second parts with respect to one another among a separated position, an unlocked position, and a locked position,
wherein, when in the separated position, the first and second parts are not mechanically or electrically connected to one another,
wherein, when in the unlocked position, the first pin is received in the second cam slot and the second pin is received in the first cam slot with the first and second parts angled with respect to one another such that the first and second parts are not mechanically locked to one another, and
wherein, when in the locked position, the first pin is received in the second cam slot, the second pin is received in the first cam slot, the first blade is received in the second blade slot, and the second blade is received in the second blade slot with the first and second parts being in-line with one another such that the first and second parts are mechanically and electrically connected to one another.

2. The separable clasp connector of claim 1 , wherein the first and second parts are identical to one another.

3. The separable clasp connector of claim 1 , wherein the first and second connector barrels are configured to be crimped to the first and second electrical conductors, respectively.

4. The separable clasp connector of claim 1 , wherein the first and second connector barrels are brass.

5. The separable clasp connector of claim 4 , wherein the first and second connector barrels are plated, at least in regions where the first and second connector barrels are intended to contact first and second electrical conductors, respectively, with an electrically conductive material.

6. The separable clasp connector of claim 1 , wherein the first and second parts are copper.

7. The separable clasp connector of claim 6 , wherein the first and second parts are plated, at least in regions where the first and second connector bodies contact one another, with an electrically conductive material.

8. The separable clasp connector of claim 1 , wherein the first blade slot has a width that is smaller than a width of the second blade and/or wherein the second blade slot has a width that is smaller than a width of the first blade such that movement from the unlocked position to the locked position resiliently deforms the first blade slot, the second blade slot, the first blade, the second blade, and any combinations thereof.

9. The separable clasp connector of claim 8 , wherein the first and second blades further comprise a chamfer at a leading edge to assist in resiliently deforming the first and second blade slots, respectively.

10. The separable clasp connector of claim 9 , wherein the first and/or second blade further comprises a relief that can allow the first and/or second blades to resiliently deform when in the first and second blade slots, respectively.

11. The separable clasp connector of claim 1 , wherein the first and second blades, the first and second blade slots, the first and second cam slots, and the first and second pins are configured so that the first and second parts can only be moved to the locked position in a single direction and can only be moved to the unlocked position opposite to the single direction.
