Abstract

A small form factor wiring connector provides a two wire to two point connector with separate-hole insertion for two wires, by having two holes on the first casing side of the connector and a terminal connection on the opposite second side of the connector. The design works well for a pluggable or fixed-mounted connector. The separate wire insertion holes and the internal screw-driven clamping means with U-shaped wire clamp and U-shaped fixed terminal surfaces provides positive connections which will not easily loosen.

First claim

The invention claimed is:

1. A wiring connector for two wire to two point connection, comprising:
a) a connector body having a first interior area, an interior wall forming a second interior area, and a threaded through-hole in a first end wall thereof;
b) a clamping screw having a first end drive head and a second end pressing point and a non-threaded slot portion on its threaded body, the clamping screw attached to the connector body through the threaded through-hole,
c) a conductive fixed terminal located within the first interior area of the connector body, the fixed terminal having a U-shape that allows for first and second wire contact surfaces; the fixed terminal further having an extension member extending from the U-shape for connection to a circuit;
d) a wire clamp located inside the connector body and attached to the clamping screw and translatable through the first interior area of the connector body by contact with the clamping screw and the wire clamp having a surface facing the fixed terminal; the clamping screw further attached to the wire clamp through the non-threaded slot portion;
e) a spring form located inside the U-shape of the fixed terminal that biases the U-shape outwardly and provides a level of pressure on inserted wires so as to insure proper electrical connection between the inserted wires and the fixed terminal; and
f) a nonconductive housing surrounding the connector body and having first and second wire holes on a first side of the housing and a terminal hole on a second side of the housing for allowing access to the extension member;
g) whereby: wire connections are made by inserting each of the inserted wires through the first wire hole and the second wire hole, respectively, and into the connector body and against each of the first and the second wire contact surfaces of the fixed terminal, respectively; tightening the clamping screw so as to apply appropriate clamping pressure on each of the first and the second wire contact surfaces of the fixed terminal and each of the inserted wires via the surface of the wire clamp and the interior wall of the connector body.

2. The wiring connector for two wire to two point connection according to claim 1 , further comprising: a plastic shield inserted at least partially into the second interior area of the connector body and having a surface for blocking the second wire hole of the nonconductive housing.

3. The wiring connector for two wire to two point connection according to claim 1 , further comprising: the wire clamp having a shield surface for blocking the first wire hole of the nonconductive housing.

4. The wiring connector for two wire to two point connection according to claim 3 wherein the wire clamp shield surface is metal.

5. The wiring connector for two wire to two point connection according to claim 1 wherein the wire clamp is metal.

6. The wiring connector for two wire to two point connection according to claim 1 wherein the nonconductive housing includes a screw hole for allowing access to the drive head of the clamping screw.

7. The wiring connector for two wire to two point connection according to claim 1 wherein the wire clamp is conductive.

8. The wiring connector for two wire to two point connection according to claim 1 wherein the connector body is conductive.

9. The wiring connector for two wire to two point connection according to claim 1 wherein the spring form is metallic.

10. The wiring connector for two wire to two point connection according to claim 1 wherein the fixed terminal is a one piece folded member.

11. The wiring connector for two wire to two point connection according to claim 1 wherein the spring form has a U-shape.

12. The wiring connector for two wire to two point connection according to claim 1 wherein the connector body is metallic.

13. The wiring connector for two wire to two point connection according to claim 1 wherein the connector body is rectangular.
