Abstract

An apparatus includes a first electrical contact comprising a first aperture and a first insulation displacement opening. Centers of the first aperture and the first insulation displacement opening are aligned. The apparatus also includes an insulated housing comprising a first wire opening, a second wire opening, and a first electrical contact inlet extending through the first and second wire openings. The first electrical contact is at least partially inserted into the first electrical contact inlet such that at least a portion of the first aperture is aligned with the first wire opening.

First claim

What is claimed is:

1. An apparatus comprising:
a first electrical contact comprising a first wire receiving portion, the first wire receiving portion comprising a first insulation displacement connection (IDC) slot and a first strain relief slot displaced from the first IDC slot;
a second electrical contact comprising a second wire receiving portion, the second wire receiving portion comprising a second IDC slot and a second strain relief slot displaced from the second IDC slot;
an insulated housing comprising a first electrical contact inlet, a second electrical contact inlet, a first plurality of wire openings, and a second plurality of wire openings.

2. The apparatus of claim 1 , further comprising an electrical shunt, wherein the electrical shunt comprises a male contact prong configured to be received within a shunt opening of the insulated housing, the shunt opening being disposed between the first and second electrical contact inlets, wherein the first electrical contact further comprising a first shunt connector portion, wherein the second electrical contact further comprising a second shunt connector portion.

3. The apparatus of claim 2 , wherein the first shunt connector portion and the second shunt connector portion each comprise respective female contact sockets, and wherein each of the respective female contact sockets is configured to receive and form an electrically-conductive connection with the male contact prong.

4. The apparatus of claim 1 , wherein the first and second IDC slots are substantially Y-shaped and extend from outer edges of the first and second wire receiving portions so as to form tapered distal end portions at the outer edges.

5. The apparatus of claim 1 , wherein the first and second strain relief slots include distal portions and proximal portions, wherein the proximal portions are of a first average width and the distal portions are of a second average width, the first average width being less than the second average width.

6. The apparatus of claim 1 , wherein the first electrical contact further comprises a third wire receiving portion and the second electrical contact further comprises a fourth wire receiving portion, the third wire receiving portion including a third IDC slot and a third strain relief slot, the fourth wire receiving portion including a fourth IDC slot and a fourth strain relief slot.

7. The apparatus of claim 1 , wherein the insulated housing includes a plurality of curved surfaces disposed between the first plurality of wire openings and the second plurality of wire openings.

8. An apparatus comprising:
a first electrical contact comprising a first aperture and a first insulation displacement opening, wherein centers of the first aperture and the first insulation displacement opening are aligned; and
an insulated housing comprising a first wire opening, a second wire opening, and a first electrical contact inlet extending through the first and second wire openings, wherein the first electrical contact is at least partially inserted into the first electrical contact inlet such that at least a portion of the first aperture is aligned with the first wire opening.

9. The apparatus of claim 8 , wherein the electrical contact is completely inserted into the electrical contact inlet such that a narrow portion of the first insulation displacement opening is aligned with the second wire opening.

10. The apparatus of claim 9 , wherein the insulated housing further includes a base and a cap disposed over an outer surface of the base, wherein the outer surface comprises a curved portion on a first side of the insulated housing extending between the first and second wire openings.

11. The apparatus of claim 10 , wherein the cap includes an elongated opening on the first side and a shorter opening on a second side of the insulated housing, wherein ends of the elongated opening are substantially aligned with outer edges of the first and second wire openings such that the elongated opening extends over the first and second wire openings.

12. The apparatus of claim 11 , wherein the cap includes a first wire receiving tab and a second wire receiving tab extending from a surface, the first wire receiving tab on the first side and the second wire receiving tab on the second side, wherein the first and second wire receiving tabs include latching prongs that are interlocked with ridges in the base.

13. The apparatus of claim 8 , wherein the electrical contact further comprises a plurality of additional apertures and a plurality of additional insulation displacement openings, wherein the insulated housing further comprises plurality of additional wire openings, wherein the first electrical contact inlet extends through the plurality of additional wire openings, wherein a set of the plurality of additional wire openings are at least aligned with portions of the plurality of additional apertures.

14. The apparatus of claim 8 , further comprising a second electrical contact comprising a second aperture and a second insulation displacement opening, wherein the insulated housing further comprises a third wire opening, a fourth wire opening, and a second electrical contact inlet extending through the third and fourth wire openings, wherein the second electrical contact is at least partially inserted into the second electrical contact inlet such that a portion of the second aperture is aligned with the third wire opening.

15. The apparatus of claim 14 , wherein the first and second electrical contact inlets are disposed on opposing sides of a central axis of the insulated housing.

16. The apparatus of claim 15 , wherein the first insulation displacement opening is substantially Y-shaped and includes a wider portion extending from an edge of the first electrical contact.

17. The apparatus of claim 15 , wherein the first aperture and the first wire displacement opening are disposed on a wire receiving portion of the first electrical contact, wherein the first electrical contact further comprises a female connection socket extending from an edge of the wire receiving portion, the female connection socket including contact tines with ridges at ends thereof.

18. A method comprising:
partially inserting an electrical contact into an inlet of an insulated housing;
inserting a first wire into a first through-hole on a first side of the insulated housing;
inserting the first wire into a second through-hole on the second side of the insulated housing, the second through-hole displaced from the first through-hole in a direction perpendicular to a direction of extension of the first through-hole; and
compressing the electrical contact into the inlet such that a narrow portion of an insulation displacement opening of the electrical contact displaces removes insulation on the first wire to create an electrical connection between the electrical contact and the first wire and an aperture of the electrical contact compresses insulation of the first wire to create a point of contact between the electrical contact and the first wire.

19. The method of claim 18 , further comprising, after inserting the first wire into the first through-hole but prior to compressing the electrical contact into the inlet, wrapping the first wire around an inner surface of the insulated housing so as direct an end of the first wire into the second through-hole.

20. The method of claim 18 , further comprising, prior to compressing the electrical contact into the inlet:
inserting a second wire into a third through-hole on the first sid
