A novel data cable achieves good transmission quality in automotive Internet applications. The data cable has a transmission core with only a single stranded conductor pair or four conductors stranded together to form a quad. The transmission core is surrounded by a jacket having a high air content. The jacket may be a foamed sheath, or alternatively at least one spacer element that defines an annular sheath space with air gaps around the transmission core.

A liquid-tight strain relief includes a tubular-shaped bushing and a dome-shaped gland. The bushing includes a flange, a centrally-located aperture, a plurality of resilient outer fingers, and a plurality of resilient inner fingers extending from an inner wall into the aperture. The gland includes a head having a centrally-located membrane. The head is co-molded with and encapsulates the flange, resulting in a strain relief having a unitary construction. The strain relief is adapted to be inserted within an orifice of a work piece, and the outer fingers frictionally engage the work piece. A cable is inserted within the strain relief by piercing the membrane, which stretches and provides a seal against the cable. The cable is inserted through the aperture of the bushing and the resilient inner fingers flex outwardly to enable the cable to pass through, while engaging and digging into the cable to clasp it and provide strain relief.

Apparatus, assembly and method for investigating the integrity of a seal and sealant contained in a sealing fitting used in hazardous locations. The apparatus/assembly can include signal transmitters and signal receivers provided on a conduit system on either side of a sealing fitting. The apparatus/assembly can include probes placed on either side of a sealant within a sealing fitting, the probes placed in probe ports provided through the wall of the sealing fitting.

A wire harness wall-passing structure and an installation method thereof. The wire harness wall-passing structure comprises: a sleeve pipe, a pouring sealant, and at least one sealing plug, wherein the sleeve pipe is alternately filled with the pouring sealant and the sealing plug along the axis direction of the sleeve pipe; and at least one first through hole is-formed in the sealing plug, and a wire harness which can penetrate through the pouring sealant and the first through hole in the sealing plug. According to the wire harness wall-passing structure, the sleeve pipe is filled with the pouring sealant and the sealing plug, so multi-stage sealing and multi-time sealing of the wire harness are achieved, the sealing performance of the wall-passing structure is greatly improved, and the wire harness wall-passing structure is more suitable for to-be-fixed devices such as a high pressure vessel.

Disclosed is a shield connector for supporting cables such that terminals of the cables are directly connected to a terminal coupling portion inside a unit, the shield connector including: a fixing plate which includes fixing part-cable through-holes, through which the cables pass, and a holding fastening portion; and a sub assembly which includes movable part-cable through-holes, through which the cables pass, and has one surface supported by the fixing plate. The sub assembly includes: a shield plate which is in contact with shield portions of each of the cables and has the outer circumference in contact with a shield part of the unit; and a shield plate-fixing plate having one surface that fixes the shield plate. Therefore, the shield connector makes it possible to directly install the cable in the unit without the need for the separate male and female connectors.

An exterior member end cap, to be attached to an end portion of a tubular shaped exterior member from which at least one conductive path is withdrawn, is provided. The exterior member end cap includes a cap main body and a first sealing member. The cap main body is inserted into the exterior member from the end portion so as to be disposed on an outside of the conductive path. The first sealing member has a elasticity, is disposed on an outside of the cap main body in close contact with an outer peripheral surface of the cap main body, is close contact with an inner peripheral surface of the exterior member, and has a continuous bubble structure.

The present invention provides a cable joint protection box, which includes a buckle, at least one abutting piece, and a box body formed by two half-boxes. The two half-boxes are in rotatable pivot joint at one side of the box body via a pin, and the two half-boxes are buckled at the other side of the box body via the buckle. A dovetail groove is disposed on a front surface of the buckle. At least one through hole which penetrates through the buckle is disposed at a bottom of the dovetail groove in the buckle. A dovetail protrusion slidably buckled with the dovetail groove of the buckle is disposed on the box body. When the cable joint protection box is locked, the abutting piece is fixedly connected to the buckle, and the abutting piece penetrates through the through hole in the buckle and abuts against the box body.

An adaptor for retaining and suspending cabled microphones comprises a main body having a first threaded end and an opposite second threaded end with a circumferential flange separating the first and second threaded ends and extending from the main body. A bore extends longitudinally through main body. A cap threads onto the first threaded end and a nut threads onto the second threaded end. The microphone cable extends through a bore in each of the nut and the cap and through the bore 20 through main body. An O-ring is captured between the cap and main and prevents relative movement between the cable and the main body when the cap is tightened, and creates a plenum seal through the adaptor.
