Title: Fastening means for mutually attachable subassemblies
Inventor: BORST ERIC
IPC: H02B1/46
Filed: 1984-05-02
Abstract: In a pair of subassemblies, e.g. a switch housing 7 and a motor housing 1 of a hand tool, which are fastened together by a key 11 and keyway 9 connection, the subassemblies are slidable relative to each other to a stop position. In the stop position, the subassembly 7 with the key 11 is prevented from being lifted out of the open keyway 9 in the other subassembly 1 by interengaging abutments 4,12,5,13,6,14 and is prevented from sliding in the keyway 9 by a resilient tab 17 engaging behind a shoulder 15. The resilient tab 17, which remains accessible from the exterior even after the attachment, can easily be pressed into its unlocking position in order to detach the two subassemblies 1,7 from each other again. <IMAGE>
