A semiconductor device includes a semiconductor element, a laminated substrate including an insulating board and a circuit board disposed on the insulating board, the semiconductor element being mounted on the circuit board, a surrounding case having an opening, and being disposed on the outer peripheral portion of the insulating board to surround the circuit board, a relay substrate having a through hole and being disposed on the surrounding case to cover the opening, and an external connection terminal including a first end portion bonded to the circuit board, a second end portion, opposite to the first end portion, inserted into the through hole of the relay substrate from the rear surface of the relay substrate so as to be in contact with the front surface of the relay substrate, and an elastically deformable elastic portion between the first end portion and the second end portion.

Provided is a one-touch terminal for electric connection of an electric cable to industrial electrical equipment including a lightning arrester. The one-touch terminal includes a metal fitting cap and a biter capable of fastening and electrically connecting any of various electric cables (5 m PDC, etc.) including a lead wire to an upper-electrode-integrated-type coupling socket or to a coupling portion of an upper-electrode-separated-type metal fitting body of a lightning arrester in a one-touch manner. The metal fitting cap, in which a wedge-type biter having an elastic-pressing-type biting/releasing structure is mounted, is detachably mounted to a metal fitting body (or a coupling socket), thereby rapidly and precisely performing electric connection (fastening) of an electric cable (5 m PDC, etc.) to any of various connection metal fittings (a bushing terminal, a terminal clamp, a bus-bar-type terminal board, etc.).

A method for joining a cable to a connector includes: providing an electrically conductive fusible conductor joining material which has a lower melting point than that of at least one inner conductor of the cable and/or at least one contact of the connector; bringing an end of the connector to an end of the cable such that at least one inner conductor of the cable and at least one contact of the connector are opposite one another and the fusible conductor joining material is present in between; and heating the cable and/or the connector from the outside such that the heat penetrates into an interior of the at least one heated cable or the connector so the fusible conductor joining material melts and electrically connects the at least one inner conductor of the cable and the contact of the connector to one another.

A connection element for mechanical and electrical connection to a contact element of an electrical storage cell comprises a contact receptacle and a clamping device. The contact receptacle is open in a set-on direction and receives a portion of the contact element. The clamping device extends into the contact receptacle in a press-on position of the clamping device. The clamping device is formed from a shape memory alloy transferable by a phase transformation into the press-on position.

An electrical plug-in connection includes a first plug-in connection element having a plug housing with at least one blade, and a second plug-in connection element having a socket housing with at least one socket in the form of a lamella pair. The lamella pair receives a blade of the first plug-in connection element, wherein the plug-in connection includes a securing element made of a shape memory alloy. The securing element is deformed upon reaching its conversion temperature. The securing element may also exhibit a one-way memory effect, wherein it is brought, after the first and second plug-in connection elements are plugged together, to a temperature which is equal to or greater than its conversion temperature.

An apparatus can dynamically adjust, in a card edge connector including first and second positions, an opening configured to receive a printed-circuit card. The apparatus may also include a set of contacts configured to connect with a set of edges of the printed-circuit card in the second position. The apparatus may also include a set of electroactive polymers configured to adjust the set of contacts between the first position and the second position by changing thickness in response to voltages applied to electrodes positioned adjacent to opposing faces of the set of electroactive polymers. The set of electroactive polymers can also include an electroactive polymer configured to control a single contact of the set of contacts.
