Abstract

The assembly technique shown in Figure #l, eliminates a fastener which is commonly used to retain the belt clip pin, which in torn retains the belt clip, which in turn retains the belt clip spring. The part which has been eliminated is most commonly referred to as an E-ring or O-ring. The ring is used to retain one end of a headed pin, and to keep the assembly from separating, due to pin movement in the exiting direction.

LEAF SPRING AND BELT CLIP PIN SELF INTERLOCKING SYSTEM

by Jeff King

  The assembly technique shown in Figure #l, eliminates a fastener which is commonly used to retain the belt clip pin, which in torn retains the belt clip, which in turn retains the belt clip spring. The part which has been eliminated is most commonly referred to as an E-ring or O-ring. The ring is used to retain one end of a headed pin, and to keep the assembly from separating, due to pin movement in the exiting direction.

The new design utilizes an interlocking system between the spring and an undercut pin. When the spring

is pushed into position, the tight radii of the spring wraps around the small diameter of the undercut pin. This inter- ference does not allow the larger diameter sections of the undercut pin to move in either of the exit directions. The system is now locked into position with all parts captivated.

  By eliminating a piece part, a process is also elimi- nated, along with associated defects, and inspection steps. The end result is a more stable system with increased reliability.
