The cable gland comprises a gland body, a plurality of extensions, an elastomer seal, a compression member configured to rotate the plurality of extensions towards to the elastomer seal, and an earthing insert mounted in the gland body configured to electrically connect a cable to a neutral and/or grounded conductor. The cable gland is configured to provide an air-tight seal between the exterior of the cable and the elastomer seal through rotation of the plurality of extension upon the elastomer seal. The cable gland may include an o-ring and nut to secure the cable gland to a planar body. The earthing insert comprises a grounding spring in electrical communication with a metallic portion of the cable and a neutral and/or grounded conductor.

An adaptive seal for a cable gland including a body including a compression portion defining a distal surface and an insertion portion defining a proximal surface, the compression portion having an outer diameter greater than an outer diameter of the insertion portion, a plurality of insertion apertures in the proximal surface, a plurality of tubes extending from the distal surface, each having a closed end and each at least partially tapering in diameter from the distal end of the body to the closed end, and a plurality of channels, each defined between one of the insertion apertures of the body and one of the closed ends of a respective one of the tubes, wherein the body and the plurality of tubes are integrally formed a single piece of elastic material.

The invention relates to an explosion-proof arrangement (10) with an explosion-proof housing (11) which has a wall opening (23) in a housing wall (12). The wall thickness (d) of the housing wall (12) is so small that it is not possible to form a thread there in order to screw in a connecting body (15) for a line to pass through or for receiving an assembly so as to ensure protection against flame transmission. According to the invention, a connecting body (25), which has a flange (38) with a flange face (39), is inserted into the wall opening (23). The flange face (39) delimits a flameproof gap (58) by way of the housing wall (12). The dimensions of a gap or intermediate space between the connecting body (25) and a boundary face (24) of the housing wall (12), which boundary face delimits the wall opening (23), are not important. The protection against flame transmission can be provided solely by the flameproof gap (58) between the flange face (39) and the housing wall (12).

A connector for device is configured to be attached to a device housing including a hole and configured to hold an electric wire inserted into the hole, and the connector for device includes a tube-shaped housing into which the electric wire is inserted and which is configured to be inserted into one end of the hole of the device housing, and a front holder configured to be engaged with one end of the tube-shaped housing, wherein the front holder includes an electric wire holding portion to which the electric wire is held, and a locking portion that is continuous with the electric wire holding portion and configured to be engaged with the tube-shaped housing, and wherein the electric wire holding portion is positioned inside the tube-shaped housing in a state where the locking portion is engaged with the tube-shaped housing.

Disclosed are methods and apparatus for providing and installing electrical wire connector clamps that may be inserted into knockout holes from the inside of an electrical box or panel, that are capable of holding multiple wires or cables, that may be run through the connector before it is slotted into the hole, and that use only a minimal amount of interior space of the electrical box or panel. Embodiments of the present invention include semi-cylindrical units that may be folded together around one or more wires for secure engagement with the wires and with a knockout hole of an electrical box or panel. Embodiments may be used in new construction, and to replace existing connector clamps in an electrical box or panel from the inside without damaging the walls surrounding the box or panel, in order to securely hold wires in an electrical box or panel, add new wire(s), hold multiple wires, and/or increase available space inside the box or panel.

An opening shield assembly including a body portion that includes a base plate having a front side and a back side and a passageway portion having a proximal end and a distal end. The passageway portion being connected to the base plate at the proximal end. The body portion also includes a passage extending from the distal end of the passageway portion to the back side of the base plate through the passageway portion and the base plate. The passageway portion is bent between the proximal end and the distal end to form a bend.

An electric device includes a housing and a cable. The housing has a pipe bracket disposed on the housing. The pipe bracket includes an interior pathway extending from a free-end of the pipe bracket into the housing. The free-end of the pipe bracket has teeth thereon. The cable has a union nut and a sleeve. The sleeve has a crimped section attached to the cable such that the crimped section is non-displaceable. The sleeve further has a toothed annular surface. In an installed state of the cable to the housing, a feedthrough portion of the cable extends through the interior pathway of the pipe bracket and into the housing. The union nut encompasses the sleeve and is attached to the pipe bracket to thereby press the toothed annular surface of the sleeve against the teeth of the pipe bracket such that the cable is fixed rotationally to the housing.

An intermediate member that enables enhancement of ease of fabrication of a wire harness and a wire harness including such an intermediate member are provided. A wire harness is divided into an intermediate member placed in an intermediate portion of the wire harness and two terminal members placed at respective terminals of the wire harness and to be connected to equipment. After being separately fabricated, the intermediate member and the two terminal members are connected together, whereupon fabrication of the wire harness is completed. The intermediate member includes one or a plurality of intermediate conducting paths, intermediate routing path retaining means retaining a cable routing path geometry of the intermediate conducting paths; intermediate shield means covering and shielding the intermediate conducting paths; and intermediate protection means covering and protecting the intermediate conducting paths.

Embodiments of an integrated piping conduit in accordance with aspects of the present invention include a push-to-connect fitting integrated with an adaptor device and associated methods that facilitate the re-use of push fittings without damage to the fitting elements or the pipe, while also facilitating connection to boxes such as electrical boxes in a manner that meets requirements and saves time for professionals dealing with the otherwise challenging management of multiple wires, cables and/or connections. Embodiments can incorporate an integrated release pusher and locking mechanism that allows for quick locking and unlocking of piping elements within a fitting. Embodiments can also include an adaptor having integrated head and body portions, and an ear member extending at least partially radially outwardly and at least partially axially outwardly from the outer surface of the body portion.
