Abstract:
The invention relates to sealed low-voltage electric bushes used for inputting electric power and signals into sealed enclosed area, for example nuclear power stations, nuclear-powered ships, underground railways etc. The aim of said invention is to design an electric bush operational at high temperatures and exposed to open fire action. The inventive sealed electric bush comprises a pressurised body, sealed modules gasketed to the body, wires sealed in the metal tube of each module by means of polysulfone insulators, wherein at least one end of the module is provided with polyetherethetketone insulators arranged after said polysulfone insulators. Said ends of each module can be provided with an additional external insulator which is placed thereon, is embodied in the form of a socket obtainable from a heat-shrinkage tubing and is filled with a heat-resistant sealing compound.
Abstract:
An integral elastomeric sealing member (10) for an electrical connector assembly (30, 100) mountable to a panel (70) has a transverse gasket section (12) and an axial seal section (16) extending rearwardly from an aperture (14) through the gasket section (12). The gasket section (12) is compressed between a mounting face (32) of the receptacle (30) and the panel (70), and the axial seal section (16) extends along the inside of the plug-receiving cavity (34) thereof and has an inner dimension just less than the outer dimension of the plug section (102) of the plug connector (100) which it seals around when the plug (100) is in mating engagement with the receptacle (30). A tapered portion (134) around the plug section (102) acts as a camming surface to gently deform the axial seal section (16) outwardly against the cavity wall (44), while the gasket section (12) is held firmly between the panel (70) and the receptacle connector (30).
Abstract:
Fiber optic protection assembly for preventing fluid from entering into fiber termination sub, including sub having disc-receiving areas and inner channel connecting disc-receiving areas. Disc-receiving areas receive plurality of discs each having a disc channel. Sub includes tension bolts, each having a bolt channel. The sub receives a fiber tube or a Fiber in Metal Tube (FIMT) comprising fiber optic cables through bolt channels, disc channels of the discs and inner channel. Discs properly seal the void in the sub to ensure protection to the insulation, center conductor and fiber tube/FIMT. When the fiber optic protection assembly is lowered into the well, hydrostatic pressure compresses the discs and O-rings of the top tension bolt ensure protection to the insulation that houses the fiber tube. Compression of the discs ensures no pressure gets to the bottom tension bolt, thus protecting fiber optic strands from hydrostatic pressure.
Abstract:
An integrated insulator sealing and shielding assembly includes a rubber housing having a plurality of radial weathersheds and a tapered end adjacent an endmost radial weathershed. The tapered end has an outer surface with a ring extending outward from the outer surface. The ring is compressible. A metal end fitting is disposed adjacent to the endmost radial weathershed and receives the tapered end. The tapered end is received in a counterbore in the metal end fitting. The counterbore has a sealing surface so that interference of the ring with the sealing surface creates a compressive sealing force to form a seal.
Abstract:
The present disclosure relates to a bushing comprising a conductor tube (20), a support tube (21), arranged within the conductor tube, a draw-rod (22) configured to run through the support tube, and a contact arrangement (26) arranged to be drawn into the conductor tube by the draw-rod. The contact arrangement comprises a sealing plug (28) arranged for sealingly engaging an inside wall of the conductor tube to prevent liquid from passing the sealing plug into the conductor tube.

An electrochemical sensor (200) includes a polymeric housing (210) and at least a first electrode within the housing. The first electrode includes an electrochemically active surface. The electrochemical sensor further includes a first connector (10) in electrically conductive connection with the first electrode. The first connector includes a first extending member (40) formed from a conductive loaded polymeric material. The first extending member is formed such that an interior thereof comprises conductive elements within a matrix of the polymeric material so that the interior is electrically conductive and an exterior surface thereof comprises the polymeric material and is less conductive than the conductive interior. The conductive interior of the first extending member is in electrically conductive connection with the first electrode. The first connector further includes a first extending conductive element (30) in electrical connection with the conductive interior. The first extending conductive element extends from the first extending member to pass through the polymeric housing. A sealing bond is formed between the polymeric material of the first extending member and the polymeric housing.
