Abstract:
1. An electrical connector comprising: an elongated generally circular-section socket part centered on an axis; an elongated generally circular-section plug part centered on an axis and coaxially fittable in the socket part in an assembled position of the connector; an axially projecting latch tab formed with a radially inwardly open hole on one of the parts; and a radially projecting latch lug on the other of the parts and fittable in the hole in the assembled position of the connector, the lug having an angularly extending angled ramp and an axially extending ramp, the latch tab being axially and angularly engageable with the ramps, each of the ramps forming an outwardly open large obtuse angle with adjacent outer surfaces of the other part, the lug being formed with an axially extending side face facing angularly oppositely to the angularly extending ramp and generally perpendicular to adjacent outer surfaces of the other part, whereby from the assembled position relative rotation of the parts in one direction cams out the tab but opposite relative rotation of the parts is blocked by the side face.
