Title:
PROTECTIVE CIRCUIT AGAINST IMPROPER CONNECTION OF CONNECTOR
Document Type and Number:
Japanese Patent JP3669426
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent misoperations of electronics and giving damages to a circuit element, caused by improper connection of a connector used in the electronics.
SOLUTION: A connector, having groups of power feed paths corresponding to each of electronic boards 3, 4, and so on has a group of first paths (C-21a, C-22a, and so on) having the number of paths L (L≥2), in which the power supply path passes through one end of both connecter terminals, a group of second paths (C21-b, C22-b, and so on) having the number of paths M (M≥2) in which the power supply path backs through the central part, and a group of third paths n (C21-c, C22-c, and so on) of the number of paths N (N≥2) in which the power supply path re-passes through the other end, and one path is selected from among the three groups of paths respectively, so that the path may be different from the other for each electronic substrate, and the paths are connected in series via connector external wires P1, P2, thereby feeding power to the electronic boards 3, 4, and so on.
