Abstract

A module of a terminal block ( 100 ) comprises a body ( 104 ) having an input configured to be coupled to an input wire and an output configured to be coupled to a plurality of output wires, a conductive element disposed within the input, and a plurality of terminals, each terminal having a first portion and a second portion configured to be coupled to an output wire, wherein the first portions of the plurality of terminals are nested together to achieve a single conductive structure, and wherein the conductive element is configured to engage and compress the input wire against the single conductive structure.

Claims (39)

1. A module of a terminal block, the module comprising:

a body having an input configured to be coupled to an input wire and an output configured to be coupled to a plurality of output wires;

a conductive element disposed within the input; and

a plurality of terminals, each terminal having a first portion and a second portion configured to be coupled to an output wire,

wherein the first portions of the plurality of terminals are nested together to achieve a single conductive structure that includes the first portions of the plurality of terminals folded onto one another to form a substantially flat contact surface, and

wherein the conductive element is configured to engage and compress the input wire against the single conductive structure.

2. The module of claim 1 , wherein the body of the module further has an opening configured to receive the at least one input wire and a hoop having an internal chamber configured to communicate with the opening and to receive the at least one input wire.

3. The module of claim 1 , wherein the body of the module further has a cavity and wherein the first portions of the plurality of terminals are located within the cavity.

4. The module of claim 1 , wherein at least two of the plurality of terminals are constructed from a same piece of conductive material.

5. The module of claim 1 , wherein at least one of the plurality of terminals is configured to be coupled to a quick connector.

6. The module of claim 1 , further comprising a bracket coupled to the body of the module, wherein the bracket is configured to be coupled to a DIN rail.

7. The module of claim 2 , wherein the conductive element includes a screw, and wherein the conductive element is configured to be depressed into the interior chamber when the screw is turned.

8. The module of claim 2 , wherein the opening is configured to receive an input wire with a size of 12 AWG to 4 AWG.

9. The module of claim 1 , wherein the plurality of terminals are configured to be coupled to an output wire with a size of 20 AWG to 10 AWG.

10. The module of claim 1 , wherein the plurality of terminals includes four terminals.

11. A method for coupling an input wire to a plurality of output wires, the method comprising:

providing a terminal block;

providing a module within the terminal block, the module having a body including an input configured to be coupled to the input wire and an output configured to be coupled to the plurality of output wires;

providing a conductive element within the input; and

providing a plurality of terminals, each terminal having a first portion and a second portion configured to be coupled to an output wire,

providing a single conductive structure, the single conductive structure comprised of nested first portions;

inserting the input wire into the input;

compressing the input wire against the single conductive structure with the conductive element; and

coupling each one of the plurality of output wires to one of the plurality of terminals,

wherein providing the single conductive structure includes providing a substantially flat contact surface that includes the first portions of the plurality of terminals folded on top of one another.

12. The method of claim 11 , wherein providing the plurality of terminals includes providing at least two terminals that are constructed from a same piece of conductive material.

13. The method of claim 11 , wherein coupling each one of the plurality of output wires includes coupling at least one of the plurality of output wires to one of the plurality of terminals with a quick connector.

14. The method of claim 11 , further comprising coupling the terminal block to a DIN rail.

15. The method of claim 11 , further comprising:

providing a screw within the conductive element; and

tightening the screw to depress the conductive element and compress the input wire against the single conductive structure.

16. A terminal block comprising:

a plurality of modules, the modules coupled together and each module comprising:

a body having an input configured to be coupled to an input wire and an output configured to be coupled to a plurality of output wires;

a conductive element disposed within the input;

a plurality of terminals, each configured to be coupled to an output wire; and

means for coupling the input wire to the plurality of terminals via a single conductive structure, the single conductive structure including portions of the plurality of terminals folded onto one another to form a substantially flat contact surface.

17. The terminal block of claim 16 , wherein the plurality of modules includes four modules and the plurality of terminals includes four terminals.

18. The terminal block of claim 17 , wherein the terminal block has a width of about 50 mm, a height of about 40 mm and a length of about 51 mm.
