Abstract: An electric connection box 10 comprises a connection box body 11, which includes a plurality of projecting tab terminal portions 13a connected respectively to one ends 31 of relay terminals 30, and a support seat 20 on which the one ends 31 of the relay terminals 30 are seated in such a manner that the tab terminal portions 13a pass through the support seat, and a cover 40 which includes terminal insertion ports 42 opposed respectively to the tab terminal portions 13a, and terminal receiving portions for respectively receiving the relay terminals 30. The cover covers the relay terminals 30 and the connection box body 11, and terminal portions 52 of an electric part 50 are adapted to be inserted respectively into the terminal insertion ports 42. The terminal portions 52 of the electric part 50 are passed respectively through the terminal insertion ports 42 in the cover 40, and are connected respectively to the other ends 32 of the relay terminals 30.

Abstract: A wire-circuit sheet includes: a resin sheet with circuit connecting holes, wires lying across the circuit connecting holes , and at least on cutting hole to punch the resin sheet so as to cut simultaneously the wires. Further, a wire-circuit sheet and its manufacturing method include: a resin sheet on which a plurality of wires lie as crossing or coming close to each other, cutting holes being provided at the crossing or close points of the plurality of wires to cut off the wires and the sheet together, and the wires being fixed and sandwiched in between laminated resin sheets with a sticky surface.

Abstract: In a connector fixing construction, connectors are mounted on a printed circuit board, and wall portions, covering peripheral surfaces of the connectors, respectively, are formed on a cover covering the printed circuit board. Therefore, even if a lateral external force acts on the connector when a mating connector is inserted into and removed from the connector, the connector is prevented from being moved laterally, thereby certainly preventing damage, such as a crack, to solder portions by which terminals of the connector are connected to a circuit pattern.

Abstract: A voltage regulating circuit for automotive vehicles includes: a supply voltage; a load; and a Positive Temperature Coefficient ("PTC") resistance element connected in series between the supply voltage and the load, for regulating voltage applied from the supply voltage to the load creating by a voltage drop across the PTC element. The PTC element includes a PTC element body substance; electrode plates provided on both side surfaces of the PTC element body substance; connection terminals provided for the respective electrode plates; and a return portion provided for at least one of the electrode plates or the connection terminals, for adjusting resistance of the element.
