A flexible jumper strip has a V-shape for the ends of its leads in order to increase its mechanical strength. In one embodiment the ends of the leads are folded back to give even more strength. In making the jumper strip conductor leads are formed on a conductor sheet laminated to an insulator sheet. Then the lead ends are given a V-shape with a mechanical punching device.

A wiring structure includes a board assembly and pin terminals. In each of pin terminal insertion holes formed in the board assembly, a terminal connection portion electrically connected to a metal foil wire and fitted onto the pin terminal so as to hold the pin terminal is provided in a through-hole of at least one of a plurality of circuit boards forming the board assembly, which forms a part of the pin terminal insertion hole, whereas an insulating sleeve blocking contact between the pin terminal and each of the remaining circuit boards is fitted into through-holes of the remaining circuit boards, which form the remaining part of the pin terminal insertion hole.
摘要:
A novel surface-mount electrical component for mounting on a circuit board. The electrical component includes at least one pin and a retaining surface. The pin serves as both a point of electrical contact between the electrical component and the circuit board and as a solder-anchoring point. The retaining surface is remote from the pin and serves as an additional solder-anchoring point for restricting the movement of the electrical component on the circuit board. Both the pin and the retaining surface are coplanar, ensuring even soldering of the electrical component to the circuit board.

In a relay module device, a signal converting section transmits driving signals of switching elements when receiving input signals from an external device and sets a relationship between the input signals and the driving signals. The relationship includes a first mode in which the signal converting section transmits the driving signals to separately control one of the switching elements with respect to one of the input signals, and a second mode in which the signal converting section transmits the driving signals to concurrently control two or more of the switching elements with respect to one of the input signals.

An insert mounting and a method for inserting and mounting components in holes of printed wiring boards, in particular for plug connectors or parts thereof, include connection pegs of two components being inserted in a T-shaped basic configuration into a hole in a printed wiring board from opposite sides of the printed wiring board, for fastening the two components in the printed wiring board hole. The connection pegs have a rectangular basic cross sectional shape. One of the connection pegs forms a crossbar of the T-shaped basic configuration and is introduced first into the printed wiring board hole. At least one of the connection pegs is elastically deformable for forming an elastic insertion zone of the connection pegs of the two components in a state in which the connection pegs are disposed in the printed wiring board hole.

In the case of the relay, connecting elements which are anchored in the base body are passed out of the base body (1) at the side and are bent at right angles to the base plane as push-in posts (12). The push-in posts (12) are formed by sections which are rolled in in the form of sleeves or channels are bent outwards from the contour of the relay structure with an axis at right angles to the base plane and form pushing-in shoulders (14) with their respective upper edge.
摘要:
A plurality of flat elongate flexible metallic strips are arranged in spaced parallel relationship within a length of flat flexible dielectric material so that the curled tubular ends of the strips are exposed at either end of the dielectric material to provide contact means thereat. Stiffening means which may comprise coined rib portions are interposed between the exposed tubular ends and the central portion of the strips to prevent flexing of the metallic strips at their juncture with each end of the dielectric material.
