Abstract

A switchboard unit circuit having functional components, such as relays and switches is formed using a wiring board device including a board, a wiring, e.g., a printed wiring, on the board, and board connectors connected to the wiring and provided to permit selective connection of the functional components to selectively form any one of a plurality of designs of unit circuits. The functional components and the wiring board device are disposed in or on a unit housing, and the board connectors are selectively connected to the functional components to selectively form a desired one of said plurality of designs of unit circuits.

Claims

1. A unit circuit intermediate assembly used for forming a desired one of a plurality of design of switchboard unit circuits, comprising:

a unit housing;

functional components of the unit circuits; and

a wiring board device;

wherein at least some of said functional components and said wiring board are disposed in said unit housing; and

wherein said wiring board device comprises;

a board;

a wiring formed on the board;

board connectors connected to the wiring and for permitting selective connection of said functional components to form said plurality of designs of unit circuits; and

component connectors for removably connecting to said board connectors and for selectively connecting different parts of a desired functional component to different respective board connectors to form said plurality of designs of unit circuits.

2. The assembly of claim 1, wherein the board connectors are of a normally-open type to permit selective connection of a short-circuiting connector to the board connector which is to be short-circuited.

3. The assembly of claim 1, wherein the board connectors are of a normally-closed type to permit selective connection of an opening connector to the board connector which is to be opened.

4. The assembly of claim 1, wherein said functional components include at least one of a circuit breaker, an electromagnetic switch, an auxiliary relay, a push-button switch, and a selection switch.

5. The assembly of claim 1, further comprising wires each having one end connected to the functional component and having the other end connected to a component connector that can be connected to the board connectors.

6. The assembly of claim 1, further comprising terminals provided in the unit housing for connection with additional functional components provided outside the unit housing, said board connectors also permitting selective connection of said additional functional components to form said plurality of designs of unit circuits.

7. The assembly of claim 1, wherein at least some of said functional components and said wiring board device are disposed on said unit housing.

8. The assembly of claim 1, further comprising flexible wiring for removably connecting the functional components and the component connectors.

9. A wiring board device for forming a desired one of a plurality of design of switchboard unit circuits having functional components, comprising:

a board;

wiring on the board;

board connectors connected to the wiring and for permitting selective connection of said functional components to form said plurality of designs of unit circuits; and

component connectors for removably connecting to said board connectors and to the functional components to permit selective connection between different parts of desired ones of the functional components to different respective board connectors to form said plurality of designs of unit circuits.

10. The device of claim 9, wherein the board connectors are of a normally-open type to permit selective connection of a short-circuiting connector to the board connector which is to be short-circuited.

11. The device of claim 9, wherein the board connectors are of a normally-closed type to permit selective connection of an opening connector to the board connector which is to be opened.

12. The device of claim 9, wherein said functional components include at least one of a circuit breaker, an electromagnetic switch, an auxiliary relay, a push-button switch, and a selection switch.

13. The device of claim 9, wherein said wiring is a printed wiring.

14. The device of claim 9, further comprising flexible wiring for removably connecting the functional components and the component connectors.

15. A method of forming a desired one of a plurality of design of switchboard unit circuits having functional components, comprising the steps of:

disposing at least some functional components in a unit housing;

providing a wiring board device including a board, a wiring on the board, and board connectors connected to the wiring and for permitting selective connection of the functional components to selectively form a plurality of designs of unit circuits;

disposing the wiring board device in the unit housing;

removably connecting the functional component to the board connectors to selectively form a desired one of said plurality of designs of unit circuits; and

removably connecting between different parts of a desired ones of the functional components to different respective board connectors by at least one component connector to form said plurality of designs of unit circuits.

16. The method of claim 15, wherein the board connectors are of a normally-open type, and said method further comprises:

selectively connecting short-circuiting connectors to the board connectors which are to be short-circuited.

17. The method of claim 15, wherein the board connectors are of a normally-closed type, and said method further comprises:

selectively connecting opening connectors to the board connectors which are to be opened.

18. The method of claim 15, wherein said functional components include at least one of a circuit breaker, an electromagnetic switch, an auxiliary relay, a push-button switch, and a selection switch.

19. The method of claim 15, further comprising the steps of:

providing terminals in the unit housing; and

selectively connecting additional functional components provided outside the unit housing, via the terminals to the board connectors.

20. The method of claim 15, further comprising the steps of:

providing a unit circuit intermediate assembly comprising a unit housing,

disposing at least some of said functional components and wiring board device in said unit housing;

connecting a first end of a wire to at least one of said functional components prior to mounting of at least one of said functional components in said housing.

21. The method of claim 20, further comprising the steps of:

providing a component connector to a second end of each wire connected to the at least one of said functional components and;

connecting the component connector to the board connector.

22. The method of claim 20, wherein at least some of said functional components and said wiring board device are disposed on said unit housing.

23. The method of claim 15, wherein at least some of said functional components and said wiring board device are disposed on said unit housing.
