A holding frame for a heavy plug-type connector can receive identical and/or different plug-type connector modules. The holding frame comprises a main body which has two side parts which lie opposite one another, and at least one fixing clip which is held at least on a side part, and by way of which the plug-type connector modules can be fixed within the main body. The at least one fixing clip has at least one holding arm which moves parallel to the plane of the side parts during the introduction of a plug-type connector module into the holding frame. As a result, plug-type connector modules can be introduced into the holding frame particularly simply and even in the installed state of said holding frame. At the same time, the holding frame variant which is shown here is more stable than the previously known holding frames which have the same functionality.

A quick-locking male connector includes: an inner contact; an insulator; an outer contact; a spring basket with a plurality of spring fingers; an elastic claw with at least radially-inward one tooth and a radially-outward nub; a connector body attached to the outer contact; and a coupling nut having at least one radially-inward extending nub. The coupling nut is movable between a rear unsecured position, in which the nub of the coupling nut is rearward of the nub of the claw, and a forward secured condition, in which the nub of the coupling nut engages the nub of the claw and forces the at least one tooth of the claw radially inward to engage with a thread of an outer conductor body of a mating female connector. The spring fingers of the spring basket apply radially-outward pressure to the outer conductor body of the mating female connector.

A connector assembly including a plurality of female connectors respectively having a predetermined number of pins, and at least one male connector having a plug terminal contacting the pin and coupled with the plurality of female connectors. The plurality of female connectors are provided to be assembled with each other along one direction.

A modular wall-mounted electrical circuit device assembly includes an electrical junction box, a modular circuit device, and a cover plate. The junction box has an open front, and is wall-mounted with exposed ends of building wiring disposed therein. The modular circuit device includes a base unit and an interchangeable device module and is installed in the junction box via the open front. The base unit has a junction box liner defining a main cavity having an open front and a closed rear, exterior electrical connection points connected to the building wiring, electrical contacts disposed in the rear, and a first electrical interconnect assembly connecting the electrical contacts to the connection points. The interchangeable device module has a forward-facing circuit device, rearward-facing electrical contacts, and a second electrical interconnect assembly. The interchangeable device module is removably installed in the main cavity, via its open front, with the respective contacts plugged together.

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.

A connection assembly for connection to an audio device includes a connector module including a connector configured for electronic connection to a mating connector of the audio device and a releasable latch configured for retaining the connector module to the audio device, an actuator engageable with the connector module and being moveable to release the latch for removal of the connector module from the audio device, and locking structure configured to selectively resist movement of the actuator to release the latch.

A connector includes a pair of housings to be fitted to each other by inserting an insertion part of one housing into a tubular part of another housing. On an outer peripheral surface of the insertion part of the one housing, a plurality of outer ribs which project from the outer peripheral surface are provided separately in a circumferential direction to extend from a front end of the insertion part to a rear side. On an inner peripheral surface of the tubular part of the other housing, a plurality of inner ribs which project from the inner peripheral surface are provided separately in a circumferential direction to extend from a front end of the tubular part to a rear side. The outer ribs and the inner ribs are provided such that positions in the circumferential direction are deviated from each other.

With the aim of addressing the problem of maintaining a state in which a plurality of connectors are securely mated, the present disclosure teaches a connecting structure S that is a structure for connecting a first connector 1 and a second connector 2. The first connector 1 comprises a first housing 11 provided around the first connection terminal 10 and having at least one opening, and the second connector 2 comprises: a second housing 21 which is provided around a second connection terminal 20 and has an engaging portion 22 which engages with an opening 12 formed in the first housing 11 in a state in which the first connection terminal 10 and the second connection terminal 20 are mated and said second housing 21 is mated with the first housing 11; and a locking member 24 which is able to move in a longitudinal direction of the connecting structure S and prevents displacement of the engaging portion 22 in a direction of disengagement from the opening 12 in a state in which said locking member 24 is pushed in up to a predetermined position on the first connector 1 side.
