A cable gland for an armored cable comprising at least an exposed portion of the armor, comprising a clamping ring and a compression ring intended to be tightened or rotatably engaged to each other, said cable gland comprises a current conducting circular member, intended to surround the exposed portion of the armor of said cable and being attached at one end to the compression ring and at another end to the clamping ring, so that when the clamping ring and a compression ring are tightened or rotatably engaged to each other, the circular member is collapsed against an exposed portion of the armor of the cable.

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 method for passing an electrical cable through a hole in a housing of a unit of electrical equipment is provided. The method may include: fitting onto the cable a tubular, mushroom-shaped male member comprising a stem with a threaded portion and a portion with enlarged head; inserting into the hole the cable having the male member fitted thereon extending through said hole with said portion with enlarged head abutting against the periphery of the hole externally to the housing and said threaded portion protruding inside the housing; and retaining said male member in the hole by coupling with said threaded portion that protrudes inside the housing an annular female member in the form of a nut co-operating with the periphery of the hole inside said housing to counter the movement of the female member with respect to the housing.

The present disclosure discloses an electrical receptacle assembly. The electrical receptacle assembly comprises a housing with a first compartment and a second compartment with at least one third opening for receiving power supply cables. The first compartment has a second opening for receiving a switch knob, defined with central axis. A base of the second compartment fitted with a switch assembly in the housing. The switch assembly defines a spindle which is required to align axially with the central axis of the slot of the switch knob. A first and a second switch assembly mounting locations on the base mounts the switch assembly. The first mounting location is used when the power supply cables are positioned to enter the receptacle from operatively below the receptacle and the second mounting location is used when the power supply cables are positioned to enter the receptacle from operatively above the receptacle.

A cable attachment device for sealing and retaining a communications cable entering a telecommunications closure through an opening defined in the closure is disclosed, the device comprising: a housing having a passage through which the communications cable extends, the housing having a first portion and a second portion; wherein the first portion of the housing is configured to receive a protective tube of the telecommunications cable; wherein the second portion of the housing is configured to engage with the closure; a first seal configured to form a seal between the device and the closure; a second seal configured to form a seal between the interior of the device and the protective tube; a third seal configured to seal between the communications cable and the interior of the device; a first retaining arrangement configured to couple the device to the closure; a second retaining arrangement configured to hold the tube relative to the device; and a third retaining arrangement configured to fix the telecommunications cable relative to the device.

A dispenser apparatus for a curable liquid material is disclosed. The apparatus comprises a flexible bag defining a first compartment for accommodating a first component of a curable liquid material, and a second compartment for accommodating a second component of the curable liquid material and adapted to communicate with the first chamber to enable mixing of the first and second components to initiate curing of the curable liquid material. A first clamp temporarily prevents mixing of the first and second components, and an elongate nozzle communicates with the second compartment to dispense the mixed curable liquid material therefrom. A second clamp temporarily prevents passage of the curable liquid material from the second compartment to the nozzle.

An example threaded cable connector for a cable with a conductor and a surrounding shielding braid, comprising a base element, a first tightening nut and a first clamping element is presented herein. The base element includes a base for fastening the base element to a housing and a passage opening for the passage of the cable about which an encircling first thread is oriented. On a side facing away from the housing, the base element has a contact surface encircling the passage opening. The first tightening nut comprises a second thread for operatively connecting the first tightening nut to the first thread of the base element. The first clamping element has a first clamping surface and, in the mounted state, is arranged between the contact surface and the first tightening nut. The first clamping element, in the mounted state, presses the shielding braid against the contact surface.

A grommet for use in a cable fitting includes a body having a bore substantially therethrough and a resilient membrane located within the bore. The resilient membrane is elastically deformable from a receiving position before the cable is inserted into the bore, to an inserted position, after the cable is fully inserted into the bore. In the receiving position, the resilient membrane is substantially conically shaped having an apex substantially coincident with an insertion opening of the body, and, the resilient membrane is axially displaced during the insertion of the cable to an inverted position with respect to the receiving position where the apex is oriented away from the insertion opening. The resilient membrane has a thinner membrane portion extending from the apex towards the bore to provide a controlled tear during cable insertion. The body has an exit opening which comprises resilient gripping teeth projecting axially from the body with an axially extending resilient foldable membrane located between at least two adjacent resilient teeth and foldable therebetween when they are radially compressed. Once force is applied by the axial movement of the fitting assembly onto a tapered surface of the grommet, the flexible gripping members radially collapse towards an inserted cable. The combination of the resilient membrane and the axially extending teeth separated by a foldable membrane allow for an increased friction fit and sealing interface on the cable. The grommet may be assembled in a strain relief connector having a nut, a connector body and optionally an insert. The insert has a removed section longitudinally coincident with a gripping surface facilitating movement of the gripping surface towards the cable.

A grommet attachment structure and a grommet that make it possible to stabilize the force for fixing the grommet to a component. The grommet includes a main body portion that is tubular, lip portions that project from the inner peripheral surface of the main body portion and can come into contact with the outer circumferential surfaces of components, and fold back portions that are provided at positions on the main body portion on end sides in the axial direction relative to the lip portions, and that cover the formation regions of the lip portions when folded back to the outer side.
