Abstract: A fuse clip assembly includes opposed clamping arms defining a pocket for receiving a fuse terminal ferrule. A rejection member, secured in operative relation with the fuse clip, includes a body arranged transversely of the pocket beyond the clip and three rejector arms extending from the body toward the clip. Two of the rejector arms are situated in opposed, spaced relation immediately above the pocket, while the third rejector arm is situated between the clamping arms beneath the pocket. The arms carry interference portion to obstruct the path of downward or endwise insertion into the pocket of a fuse ferrule not specially keyed with an annular groove.

Abstract: A fuse holder assembly includes a fuse clip having clamping arms which define a pocket for receiving a fuse terminal ferrule. A rejection member equipped with an interference element is slideably mounted for movement between a non-rejecting position and a rejecting position with the interference element disposed within the clip pocket to obstruct the insertion of a fuse terminal ferrule which is not specially keyed with an annular groove. The rejection member further includes resilient tabs or barbs which are activated upon movement of the rejection member to its rejecting position to lock the rejection member thereat.

Abstract: A fuse clip includes a pair of clamping arms defining a fuse terminal blade receiving slot. A rejector pin, once inserted through a hole in one of the clamping arms, is prevented from being withdrawn by a spring retainer clip. The pin, which spans the slot to accept only fuse terminal blades keyed with a special notch, carries a loaded compression spring serving to rigidify its cantilever mounting to the one clamping arm.
