Abstract:
1. A spacer for correctly positioning and holding a first and a second circuit board in a subassembly, each circuit board having a first surface carrying electrical components and a second, opposite surface, the circuit boards being electrically and mechanically joined at one set of adjacent flanks by electrical wire, the spacer comprising: a first side having a peripheral rim, the second surface of the first circuit board fitting against the rim such that the first surface of the first circuit board faces outward away from the spacer; a second, opposite side having a peripheral rim, the second surface of the second circuit board fitting against the rim of the second opposite side such that the first surface of the second circuit board faces outward away from the spacer; a first outer wall around which the electrical wire extends when the circuit boards are pressed against the rims; and a second, opposite outer wall, the second wall having closely positioned clips extending in opposite directions past the first and second sides of the spacer, each clip including a resilient tab biased over a corresponding side of the spacer and located such that when the circuit boards are pressed against the peripheral rims the tabs apply a holding force against the first surfaces of the circuit boards.
