Insulation piercing electrical tap connectors
Various implementations of insulation piercing connectors are disclosed. The insulation piercing connectors include a simple and efficient design for providing electrical tap connections to a power cable for voltage detection purposes. The insulation piercing connector includes at least a top housing and a bottom housing that come together to receive the power cable. Terminal contacts are housed internally within the insulation piercing connector, and the terminal contacts are positioned to pierce the power cable when the insulation piercing connector is assembled into an operational state.
1. An insulation piercing connector, comprising:
a top housing;
a bottom housing, wherein the top housing and the bottom housing form a central aperture for holding a power cable; and
an integrated contact assembly configured to be housed within the top housing in an assembled state, the integrated contact assembly configured to electrically couple a tap wire to the power cable, the integrated contact assembly comprising a boss housing and contact tines, wherein the boss housing includes an aperture for receiving the tap wire and a fastener opening for receiving an adjustment screw configured to contact the tap wire inside the boss housing, wherein the tap wire is configured to be routed through the top housing to couple with the integrated contact assembly within the top housing in the assembled state.
2. The insulation piercing connector of claim 1 , further comprising:
an inner insulator surrounding at least a portion of the contact tines while within the top housing when the insulation piercing connector is in the assembled state.
3. The insulation piercing connector of claim 1 , wherein the central aperture is formed by a top portion of the bottom housing having a first concave portion and a bottom portion of the top housing having a second concave portion.
4. The insulation piercing connector of claim 1 , wherein the boss housing is a cylindrical shape.
5. The insulation piercing connector of claim 1 , wherein the boss housing is a cube shape.
6. The insulation piercing connector of claim 1 , wherein the top housing includes a first opening and the bottom housing includes a second opening, wherein the first opening is configured to receive a carriage bolt that extends down through to the bottom housing where a hex nut is secured to an end of the carriage bolt at the bottom housing.
7. A method of installing an insulation piercing connector, the method comprising:
inserting a tap wire through a top housing;
securing the tap wire to an integrated contact assembly by:
receiving the tap wire into an aperture of a boss housing included in the integrated contact assembly; and
fastening an adjustment screw into a fastener opening of the integrated contact assembly to secure the tape wire within the aperture of the integrated contact assembly, wherein the integrated contact assembly is configured to be housed within the top housing in an assembled state;
inserting a phase wire between the top housing and a bottom housing; and
compressing the top housing and the bottom housing into the assembled state until a piercing contact of the integrated contact assembly pierces the phase wire.
8. The method of claim 7 , wherein the top housing and the bottom housing form a central aperture.
9. The method of claim 7 , wherein the boss housing is a cylindrical shape.
10. The method of claim 7 , wherein the boss housing is a cube shape.
11. The method of claim 7 , wherein the top housing includes a first opening and the bottom housing includes a second opening, wherein the first opening is configured to receive a carriage bolt that extends down through to the bottom housing where a hex nut is secured to an end of the carriage bolt at the bottom housing.
