ABSTRACT:
A motion transmitting remote control assembly of the type for transmitting motion in a curved path including a flexible motion transmitting core element, a conduit for supporting the core element and an end fitting disposed at the end of the conduit. A rod is attached to the end of the core element. The assembly also includes a swivel tube having a bore therethrough for swiveling movement relative to the end fitting and for movably supporting the rod. The swivel tube is connected to the end fitting in a swivel joint. The assembly is characterized by the swivel joint including a male swivel portion of the swivel tube and including a cup-shaped insert engaging the male swivel portion at least beyond the front face thereof. The end fitting encapsulates the end of the conduit and the insert and the remainder of the male swivel portion on the swivel tube. A method of making the motion transmitting remote control assembly is also disclosed. The method includes the steps of plugging the bore of the swivel tube contiguous with the passageway of the cup-shaped insert with the cup-shaped insert engaging the male swivel portion to prevent entry of material into the bore of the swivel tube past the front face thereof, placing the swivel tube into a mold cavity, and injecting organic polymeric material into the cavity for molding the fitting about the male swivel portion and the cup-shaped insert.
