Plug-in connector with a bushing
First Claim
1. Plug-in connector (1) comprising a bushing (2) and with an insulating member (3) arranged in the bushing (2) in a use position, and elongate contacts (4) which are fixed in holes or bores (6) located in the insulating member via projections on the contacts which engage in recesses (7), the projections extend transverse to an extension direction of the contacts (4) in the use position, the contacts or the bores (6) with the contacts (4) being located cylindrically concentric with a middle of the bushing (2) or of the insulating member and thus are located at an equal distance from an inner side of the bushing (2) or a surface (3a) of the insulating member (3), a further contact (41) being arranged in an interior of the imaginary cylinder, parallel to the other contacts (4), within a hole or bore (6), wherein the insulating member (3) has at least one groove (8) that extends around the outer surface (3a) and opens outwardly that intersects or passes through the holes or bores (6) for the contacts (4) over a portion of a radial extent thereof on a side facing the outer surface (3a) of the insulating member, and the groove (8) is arranged on the insulating member (3) at a height at which the recesses (7) of the contacts (4) are located in the use position, and a latching or retaining ring (9) is provided, formed of an insulating material and extending at least over a portion of the entire circumference of the insulating member (3), that fits into the groove (8) of the insulating member (3), and simultaneously engages in the use position as a projection into the recesses (7) of the contacts (4), and the retaining ring (9) includes at least one inwardly-projecting retaining tongue (10) which in the use position engages into a channel or perforation (11) extending inwardly from the groove (8) and projects to within a recess (7) of the further contact (41) located in the interior of the cylindrical and the hole or bore (6) receiving the contact (41).

Abstract
A plug-in connector has an insulating body which holds electrical contacts, for example contact pins or contact tubes, in bores which extend in the axial direction. On its outside, the insulating body has a groove which opens outwardly and which intersects the holes or bores for the contacts over part of their radial extension. A retaining ring fits into the groove and in the working position, simultaneously engages in groove-like recesses provided on the contacts, thereby fixing the contacts in an axial direction. The retaining ring can also support at least one retaining tongue protruding preferably radially inwardly in the plane of the retaining ring. The retaining tongue extends into the area of a further bore for a middle contact through a channel or opening in the insulating body and in the working position, engages in the recess thereof so that this middle contact is also axially fixed.
