A packer penetrator assembly comprised of a proximal mandrel, an intermediate mandrel and a distal mandrel that can be quickly and efficiently assembled while preventing the migration of gases or fluids up the ESP cable through a well bore packer. These ESP cables can be spliced to power cables passing through a wellbore packer, a sealed electrical connection at a packer assembly. The packer penetrator also offers an adaptive or male to female crossover assembly that allows use of power cables of differing diameters and styles to be joined.

A connector assembly attaches downhole tools to one another to form a tool string. The connector assembly includes male and female subs, each with latch ends that selectively latch to one another. Ends of the subs distal from their latch ends are configured for attachment to the downhole tools. A plug assembly is in one of the subs and a socket assembly is disposed in the other sub; the plug and socket assemblies mate with one another when the subs attach. Mating the plug and socket assemblies forms a signal communication path through the connector assembly so that adjacent tools are in signal communication. The plug and socket assemblies and male and female subs are annular and circumscribe a bore that extends axially through the connector assembly. Downhole tools that attach to opposing ends of the connector assembly are in communication through the bore in the connector assembly.

The present disclosure relates to a conductive slip ring for logging while drilling (LWD) instrument. The present disclosure utilizes a mechanical conductive slip ring to solve the problems of transmission of electric power and signals between two structures that have relative rotation, and the conductive slip ring has a simple structure, doesn't involve any complex circuit, and has low cost and high reliability. With the conductive slip ring in the present disclosure, there is no power transmission efficiency problem or signal transmission error rate problem. The conductive slip ring has high temperature-resistant, pressure-proof, and vibration-roof abilities, and can be applied widely.

A wire harness has: wires each including a core wire that is formed from a conductor and an insulating covering that covers the outer periphery of the core wire; and an exterior material and a braided member, into which the wires are inserted. Each wire has a removed-covering section where the insulating covering has been removed partway in the longitudinal direction. The removed-covering section is covered by a webbed covering member, the outer periphery of which has insulating properties.

A high voltage connector, connected to a device, that experiences a reduced electromagnetic interference (EMI), avoids galvanic corrosion of dissimilar metals within or without a fluid environment, and provides an effective electrical ground system. The connector includes an outer housing assembly, an inner housing mounted inside the outer housing, a set of cable reinforcement retainer assemblies secured inside the inner housing, a back cover through which the cables respectively slide along and covers a central opening of the outer housing, a braided shield covering the cables, and a clamp that connects the shield onto the outer housing. When assembling the high voltage connector, the outer housing is mounted onto the device; the inner housing is secured inside the outer housing; the set of cable reinforcement retainer assemblies with associated cables is secured in and extends in a substantially vertical direction from the inner housing; a back cover is slid along the cables, and enters and covers a central opening of the outer housing; and a braided shield is mounted and connected to the outer housing by a clamp.

A connector is provided with a cable that includes a conductor and an insulation, connector bodies that are provided on one ends in an extending direction of the cable, and a cover unit that covers and integrates each of the one ends of the cable and each of the connector bodies. The cable includes a first cohesion unit provided on a surface of the insulation at each of one ends over an entire circumference around the extending direction of the cable, and fixed to the cover unit so as to be detachable by cohesive fracture.
