A cable tray clip can couple sections of a wire mesh cable tray. The cable tray clip can include a base and a retainer rotatably coupled to the base. The retainer can be rotated to a closed position to retain one or more wires within one or more pockets on the base.

A feedthrough assembly including a sealing member including a body part having a sealing member aperture, at least one elongated member extending through the sealing member aperture, and a feedthrough member including a body part having a feedthrough aperture extending through the body part, the feedthrough member being adapted to be attached to a wall having a through hole such that the feedthrough aperture and the through hole together provide a passage through the wall. The feedthrough member is adapted to receive the sealing member in the feedthrough aperture to an operative position in which the feedthrough member is rotatable relative to the sealing member, and a gap between an outer surface of the sealing member and a surface of the feedthrough aperture is less than or equal to 250 micrometres.

A ring member is disposed on a ring member mounting position. The ring member mounting position is a region between a pair of locking walls and is formed in a straight pipe shape. The ring member is in a substantially C shape with an opening at a part of its circumferential direction. The ring member may also be formed in a ring shape being connected at ring member joint parts. The ring member includes a reduced diameter part and first click parts protruding from the reduced diameter part substantially parallel in the pipe axial direction to form a slide guide. The ring member also includes second click parts of which outer diameters expand gradually from the reduced diameter part toward their tip ends. A male fitting part and a female fitting part are fitted with each other using the above ring member to obtain an electrical conduit. A connection structure for the electrical conduits, a bell block, a method for connecting electrical conduits, a method for connecting an electrical conduit and a bell block, a pipe coupling, and a ring member can be obtained thereby. The present invention can also provide a double-wall conduit of which an outer conduit is the electrical conduit having the same structures as the male fitting part and the female fitting part, a connection structure for the double-wall electrical conduits, and a conduit line using the connection structure.

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 press fitting for an electrical conduit includes a fitting body and a press connector in a press-connection section of the fitting body to allow press-fit connection to a conduit. A conduit retainer in a conduit retainer section of the fitting body releasably grips and removably retains the electrical conduit in the fitting body before the press-connection section is deformed radially inward during the press connection process.

An insert for a clamping device for clamping an armour layer of a cable in a cable gland is disclosed. The insert comprises a body (54) adapted to be received in a cable gland and defining an aperture (60) for receiving an inner part of a cable. A clamping portion (62) is adapted to engage an armour layer of the cable to clamp the armour layer between the clamping portion and a clamping member of the clamping device when the clamping member is arranged outwardly of the clamping portion. At least part of the clamping portion is displaceable inwards as a result of engagement of the clamping portion with the armour layer clamped between the clamping portion and the clamping member.

A conduit connection system is described herein. The system has a connecting member for connecting two or more sections of conduit which are fixed and electrically connected to the conduit using grub screws. A pair of threaded sleeves cover the connecting member and seals provided on the sleeves ensure waterproofing of the conduit junction.

The present invention is directed to a cable routing system with a bracket that joins adjacent cable trays. The bracket includes a main body with upper members, a bottom member and sides. The upper members have a space therebetween to retain transverse wires of adjacent cable trays. The sides include generally C-shaped arms extending from the sides of the main body and along the back of the main body. When the bracket is secured to the adjacent cable trays a longitudinal wire of each cable tray is positioned between the upper members and the sides of the main body.
