ABSTRACT:
A molded, elastomeric strain relief 11 fits into an opening 36 in a housing 43 having an edge 37 and an edge of a wall portion 42 spaced apart by a distance less than the distance between outer edges of shoulders 17 and 18. A central portion 14 of the strain relief substantially fills the opening. An entrance end 13 with a beveled surface 27 on the same side as the shoulder 18 tapers toward the opposite side from which extends a projection 23 with a shoulder 24. The latter shoulder and the shoulder 17 grasp a barrier 56, one wall of which is the wall portion 42, and the shoulder 18 and another shoulder 28 grasp the opposite edge 37 of the opening to hold the strain relief firmly in place. Side recesses 31, 32 include shoulders against which pressure can be directed to deform the elastomeric material enough to get the shoulder 18 into the opening. Once sufficiently in, the strain relief pivots to engage the shoulder 24 behind the barrier 56.
