A wiring harness plug connector. The wiring harness plug connector encompasses a contact carrier and at least one electrical lead. The contact carrier has at least one passthrough conduit for the at least one electrical lead. The at least one electrical lead is passed through the passthrough conduit in an insertion direction. The contact carrier has, in front of the at least one passthrough conduit when viewed in the insertion direction, a partition that surrounds a sealing space. Provision is made that the sealing space is filled with a sealant in such a way, and that the sealant at least locally fills up the at least one passthrough conduit in such a way, that the at least one electrical lead is surrounded in fluid-tight fashion.

Systems and methods are provided for a wet-mate connector assembly that can include a stiffening material and a dielectric grease retainer for preventing the extrusion of dielectric grease during a wet connect. The wet-mate connector assembly can include a male portion and a female portion that can receive the male portion to form an electrical connection with the male portion. The wet-mate connector assembly can also include a dielectric grease retainer that can be positioned near the male portion and the female portion for retaining dielectric grease extruded from a contact chamber when the female portion receives the male portion. The dielectric grease retainer can seal and insulate the contact chamber. The contact chamber can be defined by an outer diameter of the male portion and an inner diameter of the female portion. The male portion and the female portion can include a stiffening material and an insulating material.

A wire connection part of a terminal fitting includes: a barrel piece which is caulked while covering a tip end of a wire, thereby being crimped to the wire; a serration part formed on an inner surface of the barrel piece and connected to a core of the wire; and a water stop part mounted on the inner surface of the barrel piece to close a gap with the wire. A projecting piece mounted anterior to the serration part to position a tip end of the core is mounted to the barrel piece. The tip end of the core is positioned by the projecting piece, whereby the positional deviation of the wire can be prevented.

A holder apparatus of a bio-signal device comprises a holder, which comprises a pocket for a bio-signal processing device, an extension with a hollow, the hollow and the pocket forming a continuous cavity through the holder, a connector, and an elastic seal with a hole. A shape of the elastic seal is matched with a shape of the hollow of the extension at an interface of the pocket, and the hollow and a shape of the hole is matched with a shape of the connector for sealing an interface between the connector and the holder while the connector and the elastic seal are within the hollow and the connector is in contact with the elastic seal. Sealant filler fills the hollow of the extension and is in physical contact with the connector, which is in the hollow against the seal, the elastic seal and the sealant filler allowing the connector to mate electrically with a counter-connector moved within the cavity in a direction from the pocket toward the hollow.

An electronic device and associated methods are disclosed. In one example, the electronic device includes a socket that includes one or more liquid metal filled reservoirs. In selected examples, the electronic devices and sockets include configurations to aid in reducing ingress of moisture.

A method for producing a multi-core cable includes arranging first and second contact elements in a contact carrier having first and second longitudinal channels connecting a contacting side to a cable side, and first and second through-openings respectively crossing the first and second longitudinal channels, and a second through-opening crossing the second longitudinal channel. The first and second longitudinal channels and the first and second through-openings are sealed in a fluid-tight manner by inserting two first sealing pieces into the first through-opening and two second sealing pieces into the second through-opening. In an injection-molding method, a connecting piece is formed connecting the contact carrier to the outer sheath of the cable by overmolding at least a rear section of the contact carrier comprising the first and second through-openings and a section of the cable protruding on the cable side.

An interface arrangement for an electric traction system of a vehicle comprises a stator housing of an electric traction motor of the electric traction system, a protective housing of a power electronics of the electric traction system and at least one contact plate of an electric interface of the electric traction motor reaching through the stator housing and the protective housing and a sealing element having the at least one contact plate reaching through the sealing element. An electric traction system for a vehicle, and a method for making a sealing element for an interface arrangement of an electric traction system of a vehicle are also provided.

An electrical connector includes: an insulative housing having a rear base and a front tongue; an upper and lower rows of contacts mounted in the insulative housing and exposed to the tongue; a shielding shell enclosing the insulative housing; and a sealing element sealing a junction between the insulative housing and the shielding shell; wherein the shielding shell includes a rear step located immediately adjacent the junction and a recess at a corner of the step, and the base of the insulative housing includes a step fitting the rear step of the shielding shell.

A dry mateable subsea electrical connector coupling, having a removable connector body adapted to couple a first connector part, terminated to a subsea cable or jumper, to a subsea sensor device, or to a subsea wet mateable connector part. The removable connector body is adapted to seal a chamber of the first connector part terminated to the subsea hose or jumper and to receive electrical conductors of the subsea sensor device or subsea wet mateable connector part. The removable connector body includes electrical conductors and fittings adapted to receive corresponding electrical conductors and fittings from the hose or jumper.
