STRUCTURE OF PRINTED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To give versatility to a circuit pattern by forming a circuit in a grid- like state and cutting off unnecessary parts from the circuit by leaving such parts that are required for the configuration of the circuit as they are. SOLUTION: In a printed circuit 5, grid-like circuits 5A are formed of conductive foil 5a and the arranging pitch P of the intersections 5c of the circuits 5A is set to the arranging pitch of male terminals in the connector inserting section of a case. A terminal inserting though hole 5d is formed in each intersection 5c of the circuits 5A and press-contacting sections 5e for press-contacting each circuit 5A with a female terminal are formed on the outer periphery of each circuit 5A. In order to obtain necessary circuit patterns 5B, 5C, and 5D in the printed circuit 5, the unnecessary part of the conductive foil 5a between each intersection 5c is cut off by forming punching holes 5f with a press, etc., by leaving the necessary parts of the foil 5a as they are. Therefore, the necessary circuit patterns 5B, 5C, and 5D can be obtained.
