A connector for connection to a substrate for mounting electronic devices. The connector includes a plurality of coupling contacts pivotably disposed within a housing. Each coupling contact is generally H-shaped and defines opposing first and second spaces. The connector also includes one or more mounting contacts partially disposed within the housing. Each mounting contact has a fastening structure joined to a bar section. The fastening structure is adapted for securement to the substrate and the bar section is disposed in a second space of at least one of the coupling contacts.

An interposer comprises a metal-plated via that spans the depth of a printed circuit board. The interposer also comprises a metal plug inserted into a first end of the metal-plated via. The metal plug is attached to the metal-plated via. The metal plug may take the form of a solid plug or a sintered via plug. The interposer also comprises a solder ball soldered to the metal plug.

An electronic assembly includes an electronic module and an electric part. The electronic module includes an electrically conductive press-fit terminal. The electrically conductive press-fit terminal has a press-fit section. The electric part has a contact hole. The press-fit section is inserted in the contact hole and plastically deformed therein, such that the press-fit section both mechanically and electrically contacts the electric part in the plastically deformed state. A corresponding method of assembly is also described.

A press-fit terminal includes a compliant part having a widened part including contact points that protrude to the outermost side along an orthogonal direction (first orthogonal direction Y) orthogonal to an insertion direction X with respect to a through hole of a board and a hole that allows deformation of the widened part toward an inside in the orthogonal direction, and is press-fitted into the through hole 23 along the insertion direction X to come into contact with an inner peripheral surface of the through hole of the board.

In a control unit including a press-fit terminal, a substrate includes: a connected portion into which the press-fit terminal is connected; and a guide member, which surrounds a periphery of the connected portion and extends from the substrate. The press-fit terminal includes: a connecting portion formed on a tip end side of the press-fit terminal; and an enlarged portion formed adjacent to the connecting portion. The guide member includes: an opening portion, which opens in a direction in which the press-fit terminal is positioned; a guide hole extending from the opening portion to the substrate; and a reduced-hole portion formed adjacent to the opening portion. The guide hole is configured such that, when the connecting portion of the press-fit terminal is connected to the connected portion of the substrate, the enlarged portion of the press-fit terminal closes the reduced-hole portion of the guide hole.

An electronic module has a first circuit board element, a second circuit board element, and a spacer. Together, the first circuit board element, the second circuit board element, and the spacer enclose a central cavity, in which components attached to the first circuit board element are accommodated. Respective annular circumferential microstructures are provided on a surface of the first circuit board element directed outward and on a surface of the second circuit board element directed outward, adjacent to an outer periphery of the first circuit board element. In this region, a sealing ring is formed, which has a form-closed connection to both the first and the second circuit board element by means of the microstructures of the first and the second circuit board element. The sealing ring can be made of a resistant plastic, which is molded on by injection molding in the liquid state in the region of the outer periphery of the first circuit board element and flows into recesses of the microstructures and, after the curing, forms the form-closed and sealing connection between the two circuit board elements and the sealing ring thereby formed.

A conductive terminal is adapted to electrically connect a wire to a circuit board. The circuit board has a through hole and solder pads on a surface of the circuit board. The conductive terminal comprises a base, a pair of mounting portions, and a pair of clamping portions. The base has a pair of opposing first edges, a pair of opposing second edges, and an insertion hole aligned with the through hole of the circuit board. The mounting portions include a pair of solder portions extending outwardly from the first edges and parallel to the base. The solder portions are each adapted to be soldered to one of the solder pads of the circuit board. The clamping portions extend obliquely toward each other from the two second edges of the base and are adapted to clamp a conductor of the wire inserted through the insertion hole and the through hole.

The system includes power-over-ethernet (PoE) sockets that interface to dedicated power and signal printed circuit boards. More particularly, the system separates power transmission circuitry from signal transmission circuitry for PoE arrays of RJ-45 sockets. The sockets include pins of different length to accommodate a stacked configuration of the power board and signal board. The pins corresponding to higher-voltage powers are a different length than lower-voltage signal pins. More than one PoE connector array may be coupled to a stack printed circuit boards, with pins of varying length, configured to engage with respective boards of the stack. The boards of the stack may be electrically isolated from each other, although the boards may be structurally engaged with each other.

An electronic assembly has an electronic module and an electric part. The electronic module has an electric terminal having a press-fit section. The press-fit section includes at least one of the following CuFeP; CuZr; CuCrZr; CuMg; CuCrTiSi; CuCrAgFeTiSi; and CuNiSiMg. The electric part has a contact hole. The electronic assembly includes a press-fit connection between the press-fit section and the electric part. In that press-fit connection, the press-fit section both mechanically and electrically contacts the electric part.

A mounting structure has a first board, an extended portion which is extended from the end portion of the first board and has a smaller thickness than the first board, and a second board having a connection terminal connected to a connector. The second board is placed on the extended portion.
