Abstract:
An electrical plug connector half connectable with another matching electrical plug connector half and comprising a housing having a cable entrance; a traction force compensator for a cable and located in the housing in a vicinity of the cable entrance; at least one contact carrier located in the housing; a cap secured to the housing at an end thereof in which the cable entrance is provided; a union overlapping the housing and an end of the contact carrier projecting beyond an end of the housing opposite the housing end in which the cable entrance is formed, the housing having axially spaced, radially projecting annular webs forming slide bearing regions for supporting the union for rotation about a longitudinal axis thereof, and the union having an inner thread for connecting the plug connector half with the matching another plug connector half; means for preventing an axial displacement of the union relative to the housing; and safety means for preventing an inadvertent rotation of the union in a direction corresponding to release of threaded connection of the plug connector halves,wherein the safety means is arranged in an annular space between the axially spaced slide bearing regions of the housing and includes a circular saw toothing provided on an inner circumference of the union and two spring bridges which are arranged opposite each other and support each two pawls cooperating with the saw toothing, wherein the plug connector further comprises a sleeve with a support band for supporting the two spring bridges, the sleeve with the spring bridges mounted thereon forming a sub-unit mountable in the housing, and wherein each spring bridge has a middle region and opposite end regions spaced form the middle region, the middle and end regions having a thickness corresponding to a width of a space between the sleeve and an addendum circle of the saw toothing, and wherein the pawls of a respective spring bridge are arranged on respective bulging regions of the spring bridge extending between the middle region and the resection opposite end regions and having a reduced thickness, the bulging regions forming resiliently deformable arms.
