An electrical connector is provided and includes an insulative housing, a plurality of conductive terminals and a metal shell. The insulative housing includes a base portion, a mating tongue protruding forwardly from the base portion and a terminal fixing portion positioned behind the base portion; a glue receiving groove is provided between the base portion and the terminal fixing portion to allow a glue to fill therein; the terminal fixing portion is provided with at least one fencing portion at a side of the terminal fixing portion adjacent to the glue receiving groove, the fencing portion is formed with a hollow recessed groove therein. The plurality of conductive terminals are provided to the insulative housing; each conductive terminal includes a mating portion exposed on the mating tongue, a soldering portion extending out of the terminal fixing portion and a connecting portion connected between the mating portion and the soldering portion; a part of the connecting portion is exposed to the glue receiving groove. The metal shell sheathes an outer circumference of the insulative housing. The present disclosure may promote the reliability of the product.

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.

A connector protector for protecting an electrical connection between a wire and an electrical connector includes a body member. The body member has a through hole for accommodating the wire. One end of the body member includes a mouth portion and the other end includes a connector cover portion configured to cover the electrical connector. The mouth portion includes a lip having a first diameter that is greater than a second diameter of a through-hole of the body member is as to define a pocket. The pocket is configured to bound a circumference of the wire and is configured to hold a resin so as to form a water-tight seal between the body and the wire. In one aspect, the resin and the body member is formed of a thermoplastic polyurethane. The resin is melted so as to fuse with the body member.

A hermetically-sealed edge-connect header that can withstand high temperatures, high pressures (or high vacuum levels), and high vibration environments, along with two corresponding connectors are disclosed. After brazing the edge-connect header components, the assembly is machined to form a slot with a portion of each of a plurality of electrical conductors removed in the machining process, resulting in a header with a high pin density. During the process of mating the first connector design to the edge-connect header, a plurality of wipers in the connector deflect, thereby causing the wipers to extend from the connector and contact the corresponding electrical conductors in the header. During the process of mating the second connector design to the edge-connect header, each of a plurality of wipers formed of low-mass, compliant metal wool, forms multiple contact points with a corresponding electrical conductor in the header.

A connector includes a housing; and an annular packing to be sandwiched between the housing and a mating component. The packing has: an annular seal portion protruding toward a radially outer side, and an annular depressed portion located on a surface of the seal portion on the radially inner side and depressed toward the radially outer side. An edge of the depressed portion is positioned on one side with respect to a protruding end of the seal portion. When the housing and the mating component are fitted to each other, the protruding end of the seal portion is in contact with the mating component, the edges of the depressed portion are in contact with the housing, and the end portion is displaced in a direction away from the housing to warp with a vicinity of the edge on the one side as a center.

A water-proof connection device and a transmission cable assembly thereof are provided. The transmission cable assembly includes a connector being USB 3.0 type C, a transmission cable, a molding holder, an insulating sleeve, and an adhesive layer. The connector has an external end portion and an opposite internal end portion. The transmission cable includes a plurality of wires connected to the internal end portion. The molding holder includes a partition portion and a pillar portion that extends from the partition portion, and connection parts of the internal end portion and the wires are embedded in the pillar portion. The insulating sleeve surrounds a part of the pillar portion and a part of the transmission cable that are arranged adjacent to each other. The adhesive layer is formed on an inner surface of the insulating sleeve, and extends outside two opposite ends of the insulating sleeve.

A molding method of a waterproof member is provided. The waterproof member is molded by molds and is for a coated electric wire. The molds include mold division surfaces including molding portions and electric wire mold clamping portions. The electric wire mold clamping portions are to sandwich the coated electric wire at sides of the molding portions. One of the electric wire mold clamping portions includes a convex portion and a side wall erected on an end of the convex portion. The other of the electric wire mold clamping portions includes a concave portion. One of the molding portions includes a side wall entering groove into which the side wall enters. The method includes molding the waterproof member accommodated in the concave portion with the waterproof member being pressed by the convex portion toward a direction in which one of the mold is attached to the other.

Provided is a connector device including a cable-side connector and a board-side connector. The cable-side connector has a cable-side housing and a plurality of cable connection terminals having pin-shaped contact portions, the cable connection terminal is configured to be connected to one end of a cable, and is provided in the cable-side housing, the board-side connector includes a board-side housing and a plurality of board fixing terminals, each board fixing terminal has a portion to be housed and an extending portion, the portion to be housed has an elastic contact piece and a closing portion, and is housed elastically displaceable inside each of a plurality of terminal housing spaces provided in the board-side housing, the extending portion extends to an outside through an opening of the terminal housing space, and is configured to be used by being fixed to a board, the elastic contact piece is configured to elastically contact the pin-shaped contact portion when the cable-side connector and the board-side connector are connected to each other, and the closing portion substantially closes the opening of the terminal housing space.
