Electrical plug connector
First Claim
1. An electrical plug connector, comprising body of at least one male connector part having a union nut which is screwed to an associated mating connector part, said union nut being secured against unintentional rotation with respect to the body by two latching means, wherein one of the latching means is integrally formed on the body, and the other latching means is arranged on the union nut, and wherein one of the latching means is in the form of a circumferential locking toothed ring, a bipartite plug housing comprises a round housing (1) and a fixing ring (4) which is firmly attached to said round housing, the fixing ring secures the union nut (2) and has a multiplicity of axially aligned, radially sprung spring arms (11) which protrude from an end face (23) of the fixing ring (4) and are uniformly distributed over a circumference of the fixing ring.

Abstract
An electrical plug connector comprises a simple and inexpensive rotation-securing element for the union nut of a water-tight plug connection which ensures reliable connection in the event of shocks and vibration, and in the process produces different values for the tightening torque and loosening torque of the screwed connection. The plug connector has a threaded union nut which is screwed to its plug housing and is secured against unintentional rotation with respect to the housing by two mutually engaging locking toothed rings having an asymmetric, sinusoidal toothed profile. The locking toothed ring which is attached to a fixing ring for the union nut is segmented, is elastically sprung and contains additional latching elements for preferred positions of the union nut.
