Abstract

A pair of opposing and stepped mating fingers extend through slots along the edges of printed circuit boards to fix or captivate the printed circuit boards between opposed steps of the fingers, A first finger 10 (Fig. l), which may be integrally formed as part of one side of a chassis or housing 11, interlockingly mates with an opposing second finger 12 which is of complementary shape and is formed on a second side of the housing 13. When the housing portions 11,13 are assembled as shown in Fig. 1, steps formed on the fingers lo,12 captivate a plurality of printed circuit boards 14,15,16 in a spaced apart, parallel and planar relationship.

PRINTED CIRCUIT BOARD INTERLOCK SYSTEM

by Tom R. Kawall

A pair of opposing and stepped mating fingers extend through slots along the edges of printed circuit boards to fix or captivate the printed circuit boards between opposed steps of the fingers,

   A first finger 10 (Fig. l), which may be integrally formed as part of one side of a chassis or housing 11, interlockingly mates with an opposing second finger 12 which is of complementary shape and is formed on a second side of the housing 13. When the housing portions 11,13 are assembled as shown in Fig. 1, steps formed on the fingers lo,12 captivate a plurality of printed circuit boards 14,15,16 in a spaced apart, parallel and planar relationship.

   As shown in Fig. 2, printed circuit board 14 has a single slot 17 at a selected position along its edge to permit placement in the relative position shown in Fig. 1, with fingers lo,12 extending therethrough. Circuit board 15 has a pair of slots 18.19 so as to fit between fingers lo,12 in the position shown in Fig. 1. Because of the slot arrangements and positioning of the slots along the edges, the circuit boards cannot be mistakenly placed in incorrect positions when the housing is assembled.
