It is aimed to provide a press-fit terminal connection structure in which a board connecting portion of a press-fit terminal is press-fit into a through hole provided in a printed circuit board and which can combine the suppression of scraping of a surface layer and a reduction of a necessary load when the press-fit terminal is inserted into and withdrawn from the through hole and an improvement of a holding force for keeping the press-fit terminal inserted in the through hole. In the press-fit terminal connection structure, the press-fit terminal includes, at least on a surface of the contact point portion, an alloy containing layer mainly containing tin and palladium, and the through hole includes a tin layer on an outermost surface of an inner peripheral surface including at least the contact point portion.

An electrical connection device includes a female connector which has a slot. A male connector has an undulated projection which is insertable into the slot. The slot has a slot width, and the undulated projection has a projection width which is greater than the slot width. The electrical connection device is capable of carrying more current that existing solder and compliant tail connections. In a second embodiment an undulated sleeve is applied to a circular connector.

Contacts that can be highly corrosion resistant, can be readily manufactured, and can conserve precious materials . One example can provide contacts having a layer of a precious-metal alloy to improve corrosion resistance. The precious-metal-alloy layer can be plated with a hard, durable, wear and corrosion resistant plating stack for further corrosion resistance and wear improvement. The resources consumed by a contact can be reduced by forming a bulk or substrate region of the contact using a more readily available material, such as copper or a material that is primarily copper based.

The present invention relates to a method for producing a high-frequency connector. The method includes producing a basic body part from a dielectric material by means of an additive manufacturing method. The basic body part has a bushing between a first end and a second end of a longitudinal extent of the basic body part and an end face at the first end for making contact with a mating connector. In addition, the method includes coating the dielectric basic body part with an electrically conductive layer and removing the electrically conductive layer in a region surrounding the bushing in each case at the end face at the first end and at the second end of the basic body part so as to form an electrically conductive coating on the outer conductor side and an electrically conductive coating on the inner conductor side. The present invention also relates to a high-frequency connector.

A component of a subsea connector includes a conductor, an electrically insulating layer and an at least partially electrically conductive layer. A method of assembling the component includes providing the insulating layer radially outward of the conductor; and applying the at least partially conductive layer onto the insulating layer by casting, moulding, compression fitting, or additive manufacturing techniques.

An electrical connector includes an insulative housing, plural conductive terminals affixed to the insulative housing, and a shielding shell enclosing the insulative housing for forming a receiving room. The insulative housing includes a base portion and a tongue portion extending forwardly from the base portion. Each conductive terminal has a contacting portion disposed in the tongue portion. The shielding shell has a first wall, a second wall opposite to the first wall, and a pair of lateral walls connecting the first wall and the second wall. The thickness of the first wall is smaller than that of the lateral walls.

A male F-type coaxial cable connector including a nut, a body, a post, and a spacer, the spacer for bearing on the nut.

A cable system component includes a nut having a seal-grasping surface portion and a seal having an elastically deformable tubular body attached to the nut. The body has a posterior sealing surface that cooperatively engages the seal-grasping surface portion of the nut and a forward sealing surface configured to cooperatively engage an interface port. The seal includes a nonconductive elastomer overlying a conductive elastomer in a radial dimension of the seal. The conductive elastomer is configured to make an electrical ground connection with the interface port before a center conductor of the coaxial cable makes an electrical connection with an internal contact of the interface port when the nut is coupled with the interface port.

A hermetic terminal for a hard disk device (HDD device) that has an excellent gas barrier property and can be assembled in a small number of man-hours, and a hard disk device are provided. The hermetic terminal for an HDD device includes a metal eyelet, insulating glass which seals the metal eyelet on a side of an inner diameter of the metal eyelet, and a lead sealed by the insulating glass to pass therethrough. The lead includes a contact made of a conductive elastic material.
