Abstract: A module element is provided for accommodating pluggable contact means and/or functional elements to provide an assembled plug connector module. The module element has a retaining contour arranged and designed in such a way that a first module element can be joined with a second module element in a transverse direction, and/or the module element has a fastening contour and at least one fastening element, which are arranged and designed correspondingly in such a way that a first module element can be joined with a second module element in the transverse direction to form the plug connector module. A plug connector module composed of at least two of the module elements described above is also provided.

Abstract: A connection device includes a bearing device for at least one spring element formed on a busbar of the connecting contact; a spring element configured to move from a first tension state in which a contact end of the spring element bears against the busbar, a second tension state in which the connection for the conductor to the busbar is closed, and a third tension state in which the contact connection for the conductor to the busbar is opened.

Abstract: A plug connector module for a modular industrial plug connector is provided, wherein the plug connector module is formed from at least two independent functional units, wherein the functional units enclose a cavity when in the assembled state together. A method for producing a plug connector module for a modular industrial plug connector is also provided, comprising: initially assembling at least two independent functional units, wherein the functional units enclose a cavity when in the assembled state together; and subsequently at least partially filling the cavity with a fixing material, whereby the functional units are fixed to one another.

Abstract: A plug connector module is provided for a modular industrial plug connector, wherein the plug connector module is formed from at least two independent functional units. In order to fit a holding frame with a plug connector module, a first functional unit is first of all combined with at least one second functional unit so as to form a plug connector module, and the plug connector module is then inserted into the holding frame.

Abstract: A problem addressed by embodiments of the invention disclosed herein consists in devising a connection device in which field terminations can be released also in the installed state, i.e., the electrical conductors can be manually disconnected using a simple tool even if the insulating body is already installed in an attachment housing. To this end, an actuator is proposed which has an inclined engagement portion with an adjoining engagement edge and engagement step by which the actuator can be lifted out of the insulating body, also from the cable connection side, with a slotted screwdriver in a single lifting movement.

Abstract: A plug connector housing has a socket housing and a screw attachment. The socket housing has an outer surface of circular cross section with an encircling first groove formed therein. The screw attachment has an inner surface of circular cross section with an encircling second groove formed therein. The plug connector housing furthermore has a circlip which is arranged with its inner circumference in the first groove and with its outer circumference in the second groove in order to hold the screw attachment rotatably on the socket housing.

Abstract: Provided is a holding frame for holding plug connector modules and for installing in plug connector casings or for screwing onto wall surfaces, wherein the plug connector modules are inserted into the holding frame and a holding arrangement on the plug connector modules cooperate with recesses provided on opposite side parts of the holding frame. Also, to allow simplified and/or less cost-intensive production with additional flexibility regarding the positioning or omission of earthing contacts, without compromising safe handling of the holding frame, one frame half has a projection in at least one fastening section, which protrudes in the direction of the other frame half and which engages with a recess in the fastening section of the other frame half in such a way that any lateral displacement of the side parts is prevented.

Abstract: A plug-in connector has a plug-in connector housing, an insulating body and a contact. The plug-in connector is rectangular and is designed to be mounted on a device wall or on another surface. The contact of the plug-in connector is also rectangular and in the form of a single piece. A two-part insulating body which is placed in the plug-in connector housing from two directions is necessary for assembling the plug-in connector.
