<p>An object of the present invention is to easily and inexpensively repair a locking function. <??>Male connectors 10, which are circuit board connectors, are accommodated in an ECU casing C, and female connectors 20 connected with ends of wire groups Wa are connected therewith. The male and female connectors 10, 20 are locked into each other by the engagement of a lock portion 45 provided on a lock arm 40 of the female connector 20 with an engaging portion 47 of the male connector 10. Here, the fracture strength of the engaging portion 47 of the male connector 10 is set to be larger than that of the lock portion 45 of the female connector 20. If a force acting in a direction to separate the two connectors 10, 20 locked into each other is to such an extent as to fracture a locking mechanism, the lock portion 45 of the female connector 20 is fractured first to cancel the locked state. This avoids the fracture of the engaging portion 47 of the male connector 10. The locking mechanism can be repaired by exchanging the female housing 21. <IMAGE></p> |
