A cable gland including a screw sleeve which can be inserted into a wall or a pipe coupling is provided. A union nut interacts with the screw sleeve, and a clamping insert is acted on by the union nut and is adapted to be pressed against a cable which is to be retained by tightening the union nut. The cable has a reinforcement and a clamping device for clamping a portion of the reinforcement is provided in the cable gland. The clamping device partially engages in the screw sleeve in an axial direction in a use position and is acted on by the union nut outside the screw sleeve. A portion of the clamping device engages in the screw sleeve and acts in an interlocking manner on an inner face of the screw sleeve in the rotation direction in the use position.

Cable fitting having a clamping device for an armor of the cable

A cable gland () for a shielded cable (), including a threaded sleeve (), a clamping insert () that engages therein, and a union nut () or pressure screw in the usual manner. The union nut or pressure screw act axially and radially upon an area of the clamping insert () protruding beyond the threaded sleeve () and radially deforms the clamping area or the clamping finger () of the clamping insert. The threaded sleeve () contains a contact device () having one or more contact fingers (), which lie against the shielding of the cable () in a contacting manner in the working position. The contact device () includes a carrier or ring () that is arranged in the threaded sleeve () in the working position and that has the one or more resilient contact fingers (), wherein the contact fingers () each have a deformable protrusion () adjacent to the carrier or ring () of the contact fingers in the axial direction, the deformable protrusion having a convex curvature or rectangular shape in the longitudinal section in the initial position, and in continuation thereof after a corresponding bend, the contact fingers extend approximately in the orientation direction of the cable (), thus in the relative insertion direction of the cable.

A connector () impermeable to liquids, having two matching connector parts () and (), which is sealed in a connected position by at least one peripherally extending circumferential sealing ring () provided between the connector pats () and (). The plug-in position is secured by a rotatable, axially fixed threaded bushing (), which is fixed in the axial direction, but rotatably supported on one of the connector parts, and the internal thread () of which is mated to the holding thread () on the other connector part. A further thread or projection or threaded part () mating with the interior thread () is provided in a loosening direction at a distance from the holding thread () interacting with the threaded bushing (), and a distance A from the end of the holding thread () to that of the further thread () is greater than a plug-in depth of the connecting pins () into the bushings (). The sealing ring () for both connector parts is disposed at a location at which it is still in the sealing position after pulling back the threaded bushing () that is detached from the holding thread (). Any sparks occurring upon loosening of the contacts are therefore shielded from the environment.

Connector impermeable to liquids

A plug () with a housing in the form of a sleeve () and an insulating body () arranged therein is provided, which retains extended contacts (), which includes an electrically conductive retainer spring () for a ground contact () having a sleeve-like plug-in piece () for the ground contact () arranged in a hole or perforation () of the insulating body (), which has a free passage in an axial direction, the plug-in piece () accommodating the retainer spring () via a lateral opening () in the insulating body (), and the hole or perforation () forms with the lateral opening () a back-cut for the somewhat elastically compressible plug-in piece (). A spring arm () extends along an outer side of the plug-in piece () arranged on the outside of the insulating body (), even when in use, which contacts the inner side of the sleeve () and has an inwardly directed projection () arranged on a free end thereof which engages in a depression or recess () on the ground contact () and fixes the ground contact () in the axial direction.

An electrical angular pin-and-socket connector () is provided which includes two individual, separate angle legs () and (). The second angle leg () includes a receiving opening () which opens perpendicularly to the profile of the angle leg, and in which a plug-in section () of the first angle leg () can be plugged and fitted, the two angle legs () and () being intermated in a functional position. In order to mutually lock the two angle legs in the functional position, an opening () extending perpendicularly to the axial extension of the first angle leg () is created through the second angle leg (), in the cover or contact region inside the receiving opening (), and part of the cross-section of the opening is respectively present in the contact region of the two angle legs, in such a way that a fixing screw () passing through the opening () or borehole positively grips the two angle legs and mutually locks the same.

Electrical angular pin-and-socket connector with mutual fixation of both angular sides

A plug connector has, in a housing, an insulating member, which in a known manner receives contact elements, for example, contact pins and/or contact sockets, which are connected to individual wires or strands of an electrical cable. The plug connector also includes a clamping member or clamping insert in order to also fix the electrical cable relative to the housing, which takes place by a clamping nut, preferably by a union nut. In order to easily assemble these parts and to maintain a given spacing in the axial direction, the insulating member and the clamping member are connected by at least one, and preferably a plurality of spacers, with a radially open interspace remaining free laterally of the spacers, and between insulating member and clamping member. The insulating member and the clamping member are preferably separate parts, which can be reciprocally connected by the spacers.

Plug connector having a housing and a clamping insert

A plug-in connector has an insulating body which holds electrical contacts, for example contact pins or contact tubes, in bores which extend in the axial direction. On its outside, the insulating body has a groove which opens outwardly and which intersects the holes or bores for the contacts over part of their radial extension. A retaining ring fits into the groove and in the working position, simultaneously engages in groove-like recesses provided on the contacts, thereby fixing the contacts in an axial direction. The retaining ring can also support at least one retaining tongue protruding preferably radially inwardly in the plane of the retaining ring. The retaining tongue extends into the area of a further bore for a middle contact through a channel or opening in the insulating body and in the working position, engages in the recess thereof so that this middle contact is also axially fixed.
