<p><P>PROBLEM TO BE SOLVED: To provide a lock mechanism of a connector in which a required state of either connection or non-connection with a counterpart connector can be surely maintained even if impact or vibration or the like arises. <P>SOLUTION: In (A) and (B), a driver is inserted into a groove 6a1 of an upper cam 6a, and the upper cam is pushed inside a hole 3b of a cover 3 by compressing a spring 8. Then, the upper cam reaches a state of (C), a lock of a pair of locked bosses 6a2 is released from a pair of lock boss grooves 3b3 of the cover. Next, when the upper cam is rotated clockwise by 90°, the upper cam reaches a state of (D) and (E). At that time, because a rectangle boss 6a3 of the upper cam and a rectangle boss hole 6b1 of the lower cam 6b are fitted, the lower cam 6b is also rotated clockwise by 90°. Therefore, the lower cam makes an actuator slide, the actuator makes a socket in contact with a pin contact. Successively, when the driver is removed from the groove, the upper cam reaches a state of (F) by an extending force of a spring. At that time, each locked boss advances into a pair of lock boss grooves 3b4 of the cover 3. In other words, the upper cam is locked by being inhibited of its rotation. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
