PROBLEM TO BE SOLVED: To provide a surface mounted contact that has superior assembling operation efficiency, light distribution characteristics and heat dissipation characteristics and extends a creepage distance from a heat sink, and a connector using the same.SOLUTION: The connector 1 includes a housing 10 and the surface mounted contact 20. The surface mounted contact 20 includes a cylindrical part 21 formed in a cylindrical shape into which only a core wire W1 of an electric wire W is inserted. At an axially intermediate part of the cylindrical part 21, a lance 22 is provided for connecting with the electric wire W and preventing it from coming off by getting into the core wire of the electric wire inserted into the cylindrical part 21. At both axially ends of the cylindrical part 21, a pair of surface mounted soldering parts 24, 25 are provided which are soldered and connected onto substrates 40, 62. Each of the pair of surface mounted soldering parts 24, 25 extends from the axial ends of the cylindrical part 21 into a direction orthogonal to the axial direction.
Abstract:
A power semiconductor device includes power semiconductor elements joined to wiring patterns of a circuit substrate, cylindrical external terminal communication sections, and wiring means for forming electrical connection between, for example, the power semiconductor elements and the cylindrical external terminal communication sections. The power semiconductor elements, the cylindrical external terminal communication sections, and the wiring means are sealed with transfer molding resin. The cylindrical external terminal communication sections are arranged on the wiring patterns so as to be substantially perpendicular to the wiring patterns, such that external terminals are insertable and connectable to the cylindrical external terminal communication sections, and such that a plurality of cylindrical external terminal communication sections among the cylindrical external terminal communication sections are arranged two-dimensionally on each of wiring patterns that act as main circuits.
Abstract:
A connecting structure for connecting a busbar base with a printed circuit board, in which the busbar base ( 11 a or 13 a) and a busbar ( 5 ) fixed to the busbar base ( 11 a or 13 a) form an electrical circuit, includes a male terminal ( 5 a) protruding from the busbar ( 5 ), and a female terminal ( 4 b) connected to a conductive pattern of the printed circuit board ( 4 ). The connecting structure is characterized in that the busbar ( 5 ) fixed to the busbar base ( 11 a or 13 a) and the conductive pattern of the printed circuit board ( 4 ) are electrically and securely connected when the male terminal ( 5 a) is fitted into the female terminal ( 4 b).

Abstract:
A method for providing pre-placed, pre-brazed feed throughs in the substrate (4) of a hermetic package corresponding to the terminal leads (6b) of the encased circuit COTS components (6). The substrate (4) may include directly bonded copper (DBC) regions forming circular shapes (10) where the holes for the special connectors of the present invention will be located. These holes will correspond to the leads of the circuit component (6) that will be mounted to it. Holes are laser or mechanically drilled into the substrate (4) inside the circular shapes (10) formed in the DBC. To form the feed through, a bushing (12), such as a blind copper rivet, is brazed in the hole, with the open end thereof oriented toward the component-side of the substrate. These open ends can accept the leads of the circuit component (6), like the holes of a conventional PC circuit board.
