ABSTRACT:
A snap-in strain relief (10) is provided for insulated cable wires (23) spread across and solder connected to thin metallic terminals (22) formed on a printed circuit board (11). The strain relief is constructed in the shape of a bar (32) having a projecting cleat (36 or 58) at one end which fits into a slot (37) or hole (62) formed in an edge section of the circuit board, and a projecting post (44) with a headed lobe (46 or 57) at the other end which is force-fitted into a hole (43) formed in the circuit board. Standoffs (47 and 48) are formed on the underside of bar to insure that the bar does not crush the insulation of the wires while applying a force to hold the wires and force isolate the soldered connections against pulling forces imparted to the cable (24).
