Abstract

A wiring board formed with electric circuits is provided, wherein said electric circuits are formed by comprising straight bus bar segments, each of the straight bus bar segments having contact portions at opposite ends thereof, said wiring board having means for bringing the respective contact portions into electrical contact

Claims

1. A wiring board formed with electric circuits, wherein said electric circuits are formed by comprising straight bus bar segments, each of the straight bus bar segments having contact portions at opposite ends thereof, said wiring board having means for bringing the respective contact portions into electrical contact.

9. A wiring board according to claim 1, wherein said wiring board is formed with guide grooves to guide said straight bus bar segments and said corner bus bar segments, said insertion holes being in said guide grooves.

10. A wiring board according to claim 1, wherein each insertion hole has an entry opening relatively wide but becoming increasingly narrow in a direction in which the tip end of the contact portion proceeds such that said contact portions inserting into said insertion hole are press fit to each other toward their tip ends.

11. A wiring board according to claim 1, wherein each contact portions of the straight bus bar segments and the corner bus bar segments is embossed to have at least one protuberance such that when the contact portions of the straight bus bar segments and the contact portions of the corner bus bar segments are inserted into said insertion holes, the protuberance of each mating contact portion are press fit to the flat surface of other mating contact portion to assure the contact therebetween.

12. A wiring board according to claim 1, wherein an oval is inserted into the insertion holes to assure that the forcibly inserted contact portions of straight bus bar segments each other and the inserted contact portions of straight bus bar segments and corner bus bar segments are brought into positive press fit each other.

13. A wiring board according to claim 1, wherein all of said straight bus bar segments are of equal length and width.

2. A wiring board formed with electric circuits, wherein said electric circuits are formed by comprising straight bus bar segments, each of the respective straight-line bus bar segments having contact portions bent at right angles at opposite ends thereof, said wiring board having insertion holes formed to receive the respective contact portions for bringing said respective contact portions into electrical contact.

3. A wiring board formed with electric circuits, wherein said electric circuits are formed by comprising straight bus bar segments and corner bus bar segments, each of said straight bus bar segments and said corner bus bar segments having contact portions at opposite ends thereof, said wiring board having insertion corner holes formed to receive the respective contact portions for bringing said respective contact portions into electrical contact.

4. A wiring board according to claim 3, wherein said corner bus bar segment is L-shaped and has contact portions at opposite ends thereof to be received into said insertion corner holes.

5. A wiring board according to claim 3, wherein said corner bus bar segment are T-shaped and have contact portions at respective opposite ends thereof to be received into said insertion corner holes.

6. A wiring board according to claim 3, wherein said corner bus bar segments are cross-shaped and have contact portions at respective opposite ends thereof to be received into said insertion corner holes.

7. A wiring board according to claim 3, wherein said corner bus bar segment has a square top surface having four sides, at least two of said four sides being formed with contact portions extending therefrom to be received into said insertion corner holes.

8. A wiring board according to claim 3, wherein said corner bus bar segments are formed with at least two contact portions to be received into said insertion corner holes formed in said wiring board, each of said insertion corner holes including at least two holes combined into one to extend at a right angle for defining a corner configuration.

14. A bus bar segment arrangement in a wiring board comprising a plurality of standardized straight bus bar segments of different lengths and widths, each straight bus bar segment having contact portions bent at its opposite ends;

and corner bus bar segments of equal widths to said straight bus bar segments, each corner bus bar segment having contact portions bent at their ends, said corner bus bar segments being L-shaped, T-shaped and cross shaped, respectively.

17. A bus bar segment arrangement according to claim 14, wherein said straight bus bar segments and said corner bus bar segments are embossed to have protuberances in positions not to interfere with each other.

15. A bus bar segment arrangement in a wiring board comprising a plurality of standardized straight bus bar segments of different lengths and widths, each straight bus bar segment having contact portions bent at its opposite ends;

and corner bus bar segments of equal widths to said straight bus bar segments, each corner bus bar segment having a top portion in square flat form and at least two contact portions extending from two neighboring side of said top portion and bent in an uniform direction.

16. A bus bar segment arrangement in a wiring board comprising a plurality of standardized straight bus bar segments of different lengths and widths, each straight bus bar segment having contact portions bent at its opposite ends;

and corner bus bar segments of equal widths to said straight bus bar segments, each corner bus bar segment having at least two contact portions bent at a right angle.
