Abstract: An electrical plug-in connection (1) for data transmission, including a plug (2) and a socket (3), the plug (2) has a plug housing (4) and a plug-in extension (5) which projects beyond the plug housing (4) and has electrical contacts (6), and the socket (3) has a socket housing (7) with a receiving channel (8) for the plug housing (4). A plug-in extension receptacle (9) with electrical mating contacts (10) is provided, and in a fully inserted state, the plug-in extension (5) is inserted into the plug-in extension receptacle (9) for connecting the electrical contacts (6) to the electrical mating contacts (10). The plug housing (4), at least in regions, is arranged within the receiving channel (8). The socket (3) has a locking device (11) for locking the plug housing (4) in the receiving channel (8) in the fully inserted state and an operating element (12), which projects beyond the socket housing (7), for releasing this locking arrangement.

Abstract: A plug part which has at least one plug part housing having at least one elongate plug region for establishing a plug connection with another plug part in a plug-in direction, wherein the plug region has at least one electrical and/or optical plug contact for establishing at least an electrical and/or optical connection with the other plug part, and at least one step is arranged between the plug region and the rest of the plug part housing, wherein the plug part housing is of integral design and the plug region has an outer contour, wherein the outer contour, apart from the ends thereof which are at the end faces as seen in the plug-in direction, is designed to be free of recesses over the entire longitudinal extent thereof in the plug-in direction, or, with at least one recess.

Abstract: Plug connector for an electrical and/or optical plug connection, wherein the plug connector comprises a first plug component and a second plug component, the first plug component has an elongate plug-in portion and the second plug component has an elongate receiving jacket portion with an insertion opening, and, in a position in which the first and second plug components are completely plugged one into the other, the plug-in portion is inserted into the receiving jacket portion through the insertion opening; the plug connector also comprises locking means including a locking pin for locking together the first and second plug components the locking pin being located inside the receiving jacket portion and/or the plug-in portion in the completely plugged-in position and being movable between the locking position and the unlocking position on a path of movement with a tangential component, viewed from the longitudinal center line.

Abstract: A jack socket to produce a electrical plug connection with a jack plug includes housing (10) with a space, in which the plug shaft can be inserted; a sleeve contact (20) to contact the contact sleeve of the jack plug; a tip contact (30) with a contact section (32) which, in the inserted state of the jack plug, can be contacted from the contact tip and a tip switching contact (40) with a contact section (42), which, without the inserted jack plug, lies against a tip switching contact contact point of the contact section (32) of the tip contact (30) and is lifted off the contact section of the tip contact (30) during the insertion of the jack plug. The connecting sections (21, 31, 41 51, 61) of the contacts (20, 30, 40, 50, 60) project from an attachment end (14) of the plug housing (10) and have a longitudinal extension.
