An electrical coupling for aerospace applications comprises an interposer arranged in use to electrically connect an electrical connector to an electrical circuit, the electrical connector comprising a plurality of electrical contacts and the electrical circuit comprising a plurality of electrical conductors. The interposer comprises a body arranged to surround each electrical contact within the connector.

An insulation film has a first surface and a second surface opposite to each other and has a first portion and a second portion extending in a direction opposite to each other from a central portion. The optical subassembly is connected to the flexible printed circuit board at the central portion with the stem opposed to the second surface. The flexible printed circuit board curves with the second surface at least the central portion facing outward. The printed circuit board intervenes between edges of the first portion and the second portion and is connected to the flexible printed circuit board. The first portion and the second portion of the flexible printed circuit board curves in a shape to avoid mutual contact and three-dimensionally intersect with each other, and the first portion and the second portion on the second surface are opposed to the printed circuit board.

A wire soldered structure includes a substrate including a main body, a first conducting layer disposed on the main body, and a through hole extending through the main body and the first conducting layer; a wire including a soldered portion that is disposed on the first conducting layer and that is adjacent to the through hole; and a solder disposed in the through hole; wherein the soldered portion of the wire is soldered to the first conducting layer of the substrate via the solder.

Disclosed herein is an electrical connector. The electrical connector comprises a flexible printed circuit comprising electrical elements on a flexible substrate. The electrical elements each comprises a solder pad and contact pad connected by a link. The electrical connector also comprises a base to at least partially surround the flexible printed circuit. The base comprises a connection interface to facilitate electrical connection with the flexible printed circuit through the base. The electrical connector further comprises a receptacle to couple to the base to partially enclose the flexible printed circuit. The receptacle exposes a portion of the flexible printed circuit to facilitate selective electrical connection with the flexible printed circuit through the receptacle.

A cable connection structure includes a cable, a sheet-like wiring member, and a cable junction connector. The cable junction connector includes a first fitting and a second fitting. A connection portion of the first fitting and a connection portion of the second fitting interlock with each other in a state in which a part of a conductor formed on the sheet-like wiring member is sandwiched between a plate portion of the first fitting and a plate portion of the second fitting. The first fitting has an insulation-displacement contact which includes an open-ended slot. The cable is forced into the open-ended slot. A direction in which the cable is forced into the open-ended slot is perpendicular to a direction in which the cable extends and is parallel to a direction in which the part of the conductor is sandwiched between the plate portion of the first fitting and the plate portion of the second fitting.
