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: The invention relates to an electric coupling element (1). Pin or socket contact elements (20), with which an electric means of a screwable connection means (28), are arranged in an electrically insulating main part (10). Openings (18) in the main part (10) are covered by means of a covering panel (30) I order to ensure the electric insulation of the individual contact elements (20). For assembly purposes, the covering panel (30) is movably attached to the main part (10) such that the covering panels (30, 30?) of two coupling elements (1, 1?) are mutually actuated when joined together.

Abstract: A plug-connector body for latching-in in a switch cabinet or the like includes pin-shaped fastening elements mounted on the plug connector body for sliding into latching slits on a carrier body.

Abstract: For an electric hermaphroditic plug-in connector a hermaphroditic contact with a plug-in area and a terminal area is proposed that consists of a solid, single-piece contact part, the plug-in area being formed as an adjacent sleeve and pin contact and a separate, elastic contact element being provided in the sleeve contact.

Abstract: For rapid and simple fastening of a plug-connector body in a carrier body which is intended for latching-in in a switch cabinet or the like, a fastening arrangement is proposed which guarantees secure fixing of said plug-connector body without any tool.

Abstract: For a holding frame for holding plug connector modules and for installation in plug connector casings or for screwing onto wall surfaces, the plug connector modules being inserted in the holding frame and holding means on the plug connector modules interacting with recesses provided on opposite wall parts (side parts) of the holding frame, it is proposed that the holding frame be constructed from two halves connected to one another in an articulated manner and that the recesses for holding the plug connector modules be constructed, in the side parts of the holding frame, as openings which are closed all round. Under these circumstances, the holding frame is unfolded for the purpose of inserting the plug connector modules and is then closed, the plug connector modules then being held in a form-locking manner in the holding frame via the holding means.
