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 plug-in connector has two pushbuttons arranged laterally thereon. An annular, asymmetric spiral spring is inserted in such a manner that the spiral spring, in its locking orientation, permits the respective pushbutton pin to move into the plug-in connector housing and prevents the pushbutton pin from moving out of the plug-in connector housing. The spiral spring can tilt from its locking orientation into its release orientation when arranged with its inner region in a release groove of the pushbutton pin. In its release orientation, the spiral spring permits the pushbutton pin to move out of the plug-in connector housing. This permits actuation similar to a ballpoint pen with only a few components and with high operating comfort.

Abstract: A protective conductor connection connects a protective conductor to a busbar of a grounding element. The grounding element extends in a plug-in direction on a wall of an isolating body of the plug connector. The grounding element has a mounting region for mounting on the wall, a contact element for electrically contacting a counterpart plug connector, and a contact surface for electrical contacting a plug connector housing. A spring element and an actuating element are provided on the mounting region and configured such that the actuating element, during actuation thereof, interacts with the spring element such that, in a first position of the actuating element, a contact connection for the protective conductor to the current rail is opened by the spring element, and in a second position of the actuating element, a contact connection for the protective conductor to the current rail is closed by the spring element.

Abstract: An insulating element for a high-power plug connector system comprises at least one stop formation for limiting the distance of insertion into the high-power plug connector system and at least one cutout, which allows contact to be established between a receivable high-power contact and at least one electrically conductive bar. The insulating element has at least one retaining formation, which is located on the periphery of the insulating element, near the stop formation.

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 locking mechanism for first and second housing parts of a housing of a plug connector, includes a push button, which extends in the axial longitudinal direction through an opening of the first housing part into the interior of the housing. The push button is movably arranged, relative to the housing, between predetermined first and second axial positions, which correspond with the first and second positions of the housing parts. The push button and an interior locking element are configured such that the push button is in pressure contact to the locking element and interacts with the locking element such that, in the case of movement of the push button from the first to the second positions a radial pressure contact between the two housing parts is provided such that a gap between the first and second housing parts is minimized.

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: Disclosed is a push-button lock for locking a plug-in connector housing. The lock has a push-button body with a cylindrical unlocking recess containing an unlocking pin. The appropriate interaction of an outer contour of the unlocking pin, an inner contour of a through-opening of the plug-in connector housing and the push-button body by at least one locking element and two springs allows the plug-in connector housing to be locked and unlocked with great ease of use, the operating concept being particularly self-explanatory.

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.
