Abstract:
A computer system comprising:a housing which houses computer system components including a circuit board and having an electronic component unit mounting area having a generally rectangularly shaped base protrusion protruding tangentially from a first plane parallel to the base of said housing and a generally U-shaped base protrusion protruding tangentially from a second plane other than the first plane, the electronic component unit mounting area of said housing further including a base fastening area, the circuit board further including a hole formed therein and aligned directly above the base fastening area of said housing; an electronic component unit subassembly having a component fastening area and a generally U-shaped recess which conforms to the U-shaped base protrusion of the electronic component unit mounting area and a generally rectangular recess which conforms to the generally rectangular base protrusion of the electronic component unit mounting area; wherein the upper face of the rectangularly shaped base protrusion inclines toward the U-shaped base protrusion along a third plane, the third plane being other than the first and second planes, such that when said electronic component unit subassembly is mounted on the electronic component unit mounting area with a force tangent to the base of said housing, the rectangular recess engages the rectangularly shaped base protrusion whereby the incline forces the U-shaped recess of the electronic component unit subassembly into fixed engagement with the U-shaped base protrusion of the electronic component unit mounting area and whereby said electronic component unit subassembly is held firmly along all of the first, second and third planes and such that alignment is achieved between the component fastening area, the hole formed in the circuit board, and the base fastening area, said circuit board further comprising an electrode, and wherein said electronic component unit subassembly further comprises a connector mounted on said electronic component unit subassembly and equipped with a compression type terminal, the terminal being connected to a lead wire of an electronic component in said electronic component unit subassembly; and a fastener which fastens said electronic component unit subassembly to the circuit board and to the base of said housing by fastening the component fastening area, the circuit board through the hole formed in the circuit board, and the base fastening area, whereby the compression terminal makes contact with the electrode, is compressed, and is electrically connected thereto.
