Definitions

• the invention relates to an angular plug carrier, in particular for attachment to an assembly housing, consisting of a base part which is fixed to the assembly housing and can be fastened in a rotationally secure manner, and a base part which partially overlaps this with its one leg and is rotatable but axially immovably connected by means of a mutual positive engagement.
• Angled support part for receiving an insulating body holding the plug contacts, the base part and the leg of the angled support part facing it being equipped in the area of their mutual overlap with a latching device for mutual fixing in a selectable rotational position of the angled support part.
• Such an angular connector carrier equipped with a latching device is known in particular from DE-OS 195 20 544, according to which it is provided that in the base part and in the associated leg of the angular carrier part provided in the region of their mutual overlap, in opposite directions, circumferential projections forming a kind of toothing in their recess base provide groove recesses with a radially resiliently elastic, along its inner or outer circumference a ground plan shape deviating from the pure circular shape and cooperating with the projections in the recess base, which is arranged at least in an intended form of implementation can be formed by a corrugated spring and in cooperation with the projections in the recess base a locking of the base part and the angular support part in a number of freely selectable pivot positions n enables.
• connection between the fixed base part and this angularly pivotable relative to its axis Carrier part forms a single part, namely the corrugated spring, on the one hand the non-detachable connection between the base and the support part and on the other hand also the negotiable mutual anti-rotation or locking of the base part and the support part in a selected rotational position.
• the known plug support requires, on the one hand, a careful design of the corrugated spring and, on the other hand, a precise design of at least the groove recess having the locking marks or the like forming radial projections, which, on the one hand, requires a relatively high level of production expenditure and, on the other hand, also brings with it a not inconsiderable complication in the assembly of the plug carrier.
• the object of the invention is to improve an angular plug carrier of the type described at the outset in such a way that, with less production outlay and a number of latchable pivoting positions between the base part and the carrier part which meet the requirements of practice, it counteracts unintentional adjustment of a set swivel angle position is sufficiently secured by lightly touching it or under the influence of vibrations which are unavoidable in machine units.

• the invention is thus distinguished on the one hand by a separation of the functions of an axial trigger safety device and a latching device for the mutually negotiable fixing of the base part and the support part and on the other hand at the same time by a limitation of the possible latched swivel positions to those in the respective application of the plug holder actually usable number, with the consequence of a comparatively inexpensive manufacturability of the individual parts and a simplified assembly of the plug carrier.
• the locking according to the invention is characterized by the interaction of flat surface pairs and thus by a relatively high locking force.

• the angular support part is in only two positions rotated by 180 ° relative to one another. Compared to the base part can be locked, however, in the interest of reducing the variety of types and thus optimizing the storage, it can be particularly advantageous if the angular support part can be locked in four different positions, in particular in each case rotated by 90 ° relative to the base part, for which purpose one
