Abstract:
An electrical connector comprising first and second connector housings respectively having a cylindrical shape with a concentric axis and having a circumferential direction, said first and second connector housings being engageable with each other by being brought together along said concentric axis;said first and second connector housings including a corresponding first and second metallic terminal connectable to each other by engaging said first and second connector housings with each other;said first connector housing comprising at least one locking arm which is elastic and flexible, while said second connector housing comprises a corresponding number of locking detents engageable with said at least one locking arm, so that said first and second connector housings are lockable with each other;said first and second connector housings further comprising a positioning device, said positioning device including at least one positioning groove formed in an inner peripheral surface of said first connector housing, and a corresponding number of positioning ribs formed on an outer peripheral surface of said second connector housing, said at least one positioning groove and rib being arranged such that they can be fitted together only when said at least one locking arm and detent are positioned and fitted in said circumferential direction of said first and second connector housings, so that, when said at least one positioning groove and rib are fitted, said first and second connector housings cannot rotate in said circumferential direction, but can move along said concentric axis, respectively relative to each other;said first and second connector housings further comprising a guide enabling said first and second connector housings to rotate in said circumferential direction and move along said concentric axis, respectively relative to each other, when said at least one positioning groove and rib are not fitted with each other.
