Abstract A semiconductor device is provided with a base plate on which a circuit board is disposed. A plurality of semiconductor elements such as diodes or transistors are supported on the circuit board and interconnected by circuit wiring. A container for the device includes side walls extending upwardly from the base plate and a top cover extending between the walls. An external terminal connection is provided by an internal terminal and an external terminal that are connected by a flexible wire within the container. The internal terminal has its lower end soldered to the circuit wiring at a predetermined location and its upper end disposed in a seat in the top cover. An upwardly extending slit within the seat receives the end of the internal terminal and a transverse window opens to the slit to receive a transverse protrusion from the upper terminal end. The external terminal extends through the cover with its lower end extending inwardly of the cover where the flexible wire is connected to it.
A semiconductor device comprising: a circuit board having a circuit wiring pattern in semiconductor elements mounted thereon; container means having a radiating plate for supporting said semiconductor elements and further having side walls and an upper cover with a terminal support seat provided therein; at least one lead-out terminal means having an internal terminal extending upwardly from said circuit board and having one end soldered to the circuit wiring at a predetermined location on said circuit board; said lead-out terminal means further having an external terminal extending through and secured to said upper cover; said internal terminal having its other end supported in said terminal support seat on the inner side of said upper cover; and a flexible wire connecting said internal and external terminals.
