Abstract: A connector having a contact carrier and a plurality of contact elements which are mounted in the contact carrier, wherein the contact carrier has a front wall and a rear wall which are connected to one another via side walls, wherein the walls define a receiving space, wherein holding webs extend through the receiving space, which holding webs each have fastening sections as well as a clamping section which is situated between the fastening sections, wherein the holding webs have at least one clamping structure in the clamping section. One contact element is clamped in an intermediate space between two adjacent holding webs by the at least one clamping structure, and at least one of the fastening sections has the structure of a joint in such a way that the holding web can be moved from a clamping position to a release position by elastic deformation of the joint.

Abstract: A modular plug connector having a holding frame having side walls which laterally delimit a receiving space, and at least one plug connector module which can be introduced into the receiving space. The side walls have a plurality of holding-frame-side guide elements and the at least one plug connector module has at least one plug-connector-module-side guide element. The at least one plug-connector-module-side guide element can be plugged into the holding-frame-side guide elements such that the plug connector module is positioned in the receiving space. The side walls have a latching structure and the plug connector module has at least one latching tongue which engages into the latching structure. The at least one plug connector module has at least one functional element with which functional element a functional contact to a functional element of a plug connector module of another plug connector can be established.
