Abstract:
An electrical connector with a coupling state indicating mechanism, comprising:a first connector having a semicylindrical projection having a curved surface and a plane surface;a second connector having a slider receiving portion and to be coupled with said first connector, said slider receiving portion being provided with a guide groove having an engaging wall to guide said semicylindrical projection, and with an abutting plane; anda slider to be slidably received in said slider receiving portion for indicating a coupling state of said first and second connectors, said slider integrally having an engaging projection to prevent coming-off thereof by engaging the engaging wall of said slider receiving portion, an oblique cam groove to receive said semicylindrical projection therein and oblique in a direction to slide said slider toward said abutting plane, a releasing groove having a closed end and continuing from said cam groove in parallel with a longitudinal axis of said slider to release said semicylindrical projection from said cam groove when said first and second connectors have completely coupled so as to return said slider to an initial position, and a spring portion to abut on said abutting plane and to be compressively transformed to bring about a force to return said slider, wherein said curved surface of said semicylindrical projection slides on a wall of said cam groove so as to slide said slider toward said abutting plane and said plane surface of said semicylindrical projection is parallel to said releasing groove so as to surely shift said semicylindrical projection from said cam groove to said releasing groove,wherein said slider is moved and abuts on said abutting plane in a process of coupling said first and second connectors and then returns to said initial position upon complete coupling thereof, and said releasing groove of said slider engages said semicylindrical projection when said second connector.
