Abstract

A tap connector that includes a tap body and an insulation piercing assembly or module is provided. The insulation piercing assembly is secured to the tap body and movable relative to the tap body. The insulation piercing assembly includes a conductive body, at least two sets of electrically conductive insulation piercing teeth secured to the conductive body and a non-conductive cap or coating covering the teeth. When the teeth pierce the non-conductive caps or coating exposing the teeth, the teeth can pierce insulation surrounding the main and tap conductors creating an electrically conductive path between the main conductor and the tap conductor.

First claim

What is claimed is:

1. A tap connector for electrically connecting a tap conductor to a main conductor, the tap connector comprising:
a tap body having a first side wall, a second side wall, a base at one end of the tap body between the first and second side walls and a cap at another end of the tap body between the first and second side walls;
a keeper positioned between the first and second side walls and movable toward and away from the cap relative to the tap body, the keeper having a tap conductor groove and a coupling member;
a stem having a stem coupling member at one end of a threaded shaft and a tool mounting member at the other end of the threaded shaft, the threaded shaft being positioned within a threaded aperture in the base of the tap body so that the stem coupling member is coupled to the keeper coupling member such that rotational movement of the stem is translated to linear movement of the keeper; and
an insulation piercing assembly movably secured to the side walls of the tap body and positioned adjacent the keeper so that movement of the keeper toward the cap can move the insulation piercing assembly toward the cap, the insulation piercing assembly being capable of piercing insulation surrounding the main conductor and the tap conductor to create an electrically conductive path between the main conductor and the tap conductor.

2. The tap connector according to claim 1 , wherein the insulation piercing member is conductive such that the main conductor teeth and the tap conductor teeth are electrically connected to each other.

3. The tap connector according to claim 1 , wherein the insulation piercing assembly comprises:
a non-conductive body;
a side wall mounting member positioned at each end of the body for movably securing the insulation piercing assembly to the side walls of the tap body; and
an insulation piercing member embedded in the non-conductive body, the insulation piercing member having one or more main conductor teeth extending from one end and one or more tap conductor teeth extending from another end;
wherein the one or more main conductor teeth are insulated until the one or more main conductor teeth penetrate insulation surrounding a main conductor, and the one or more tap conductor teeth are insulated until the one or more tap conductor teeth penetrate insulation surrounding a tap conductor.

4. The tap connector according to claim 3 , further comprising:
a flexible non-conductive main side cap releasably secured to the non-conductive body and positioned over the one or more main conductor teeth to insulate the one or more main conductor teeth until the one or more main conductor teeth penetrate the insulation surrounding the main conductor; and
a flexible non-conductive tap side cap releasably secured to the non-conductive body and positioned over the one or more tap conductor teeth to insulate the one or more tap conductor teeth until the one or more tap conductor teeth penetrate the insulation surrounding the tap conductor.

5. A tap connector for electrically connecting a tap conductor to a main conductor, the tap connector comprising:
a tap body having a base, a pair of side walls and a removable cap connected to a distal end of each of the pair of side walls, wherein the tap body is capable of securing the main conductor and the tap conductor to the tap connector; and
an insulation piercing assembly positioned between the base, the pair of side walls and the removable cap of the tap body, the insulation piercing assembly being movable at least relative to the tap body, the insulation piercing assembly comprising:
a non-conductive body having a main side, a tap side and a center pocket;
an insulation piercing member having a conductive body positioned within the center pocket of the non-conductive body, one or more main conductor teeth extending from one end of the conductive body such that the one or more main conductor teeth extend from the main side of the non-conductive body, and one or more tap conductor teeth extending from another end of the conductive body such that the one or more tap conductor teeth extend from the tap side of the non-conductive body;
a first cap made of a flexible nonconductive material attached to the main side of the non-conductive body and covering the one or more main conductor teeth, wherein the first cap is selectively pierceable by the one or more main conductor teeth to from an electrical connection between the conductive body and the main conductor; and
a second cap made of a flexible non-conductive material attached to the tap side of the non-conductive body and covering the one or more tap conductor teeth, wherein the second cap is selectively pierceable by the one or more tap conductor teeth to form an electrical connection between the conductive body and the tap conductor.

6. The tap connector according to claim 5 , wherein when the main conductor teeth pierce the insulation surrounding the main conductor the one or more main conductor teeth pierce through the first cap such that the first cap acts as a gasket to provide a watertight seal around the one or more main conductor teeth.

7. The tap connector according to claim 5 , wherein when the tap conductor teeth pierce the insulation surrounding the tap conductor the one or more tap conductor teeth pierce through the second cap such that the second cap acts as a gasket to provide a watertight seal around the one or more tap conductor teeth.

8. The tap connector according to claim 5 , wherein the first cap is permanently secured to the non-conductive body, and the second cap is permanently secured to the non-conductive body.

9. The tap connector according to claim 5 , wherein the insulation piercing assembly is movable at least relative to the tap body by sliding the insulation piercing assembly along the tap body.

10. A tap connector for electrically connecting a tap conductor to a main conductor, the tap connector comprising:
a tap body having a first side wall, a second side wall, a base at one end of the tap body between the first and second side walls and a cap releasably secured to another end of the tap body between the first and second side walls;
a keeper positioned between the first and second side walls and movable toward and away from the cap relative to the tap body, the keeper having a tap conductor groove and a coupling member;
a stem extending at least partially through the base with having one end coupled to the keeper and another end capable of being attached to a tool, the stem being movable relative to the base such that movement of the stem translates to movement of the keeper; and
an insulation piercing assembly movably coupled to the side walls of the tap body and positioned adjacent the keeper so that movement of the keeper toward the cap can move the insulation piercing assembly toward the cap, the insulation piercing assembly being capable of piercing insulation surrounding the main conductor and the tap conductor to create an electrically conductive path between the main conductor and the tap conductor.

11. The tap connector according to claim 10 , wherein the insulation piercing member is conductive such that the main conductor teeth and the tap conductor teeth are electrically connected to each other.

12. The tap connector according to claim 10 , wherein the insulation piercing assembly comprises:
a non-conductive body;
a side wall mounting member positioned at each end of the body for movably coupling the insulation piercing assembly to the side walls of the tap body; and
an insulation piercing member positioned within the non-conductive body, the insulation piercing member having one or more main condu
