RETAINING BLOCK AND MODULAR PLUG INSERT

The invention relates to a retaining block (121) for a modular plug insert (109), consisting of a retaining block member (1) with a plug-end covering surface (5), a cable-end covering surface (3), as well as an outside contour (7) which surrounds the covering surfaces (3, 5). Furthermore, the invention relates to a modular plug insert (109) with a retaining block (121) comprising a retaining block member (1) with a plug-end covering surface (5), a cable-end covering surface (3), as well as an outside contour (7) which surrounds the covering surfaces (3, 5), and with at least one contact member (93) defining a plug-in direction (S) by means of its longitudinal expansion. In order to achieve a simple and compact structure of the retaining block (121), according to the invention, at least one receiving opening (9) for receiving a contact member (93) is provided, the receiving opening extending from the plug-end (5) to the cable-end covering surface (3) and opening out into the outside contour (7) of the retaining block member (1). Compact realisation of the modular plug insert (109) with a subsequent plug arrangement which is as small as possible is enabled according to the invention in that a retaining block (1) according to the invention is utilised, wherein the contact member (93) can be introduced into the at least one receiving opening (9) along, in each case, a receiving direction (A) directed transverse to the plug-in direction (S).
