SCREW RETAINER FOR A MOLDED CASE CIRCUIT BREAKER MOVABLE CONTACT ARM ARRANGEMENT

摘要

A screw retainer is fabricated from a thin sheet of spring steel and is comprised of three sections: a screw support section, a leg support section and a leg section. The screw support section contains a through-hole for receiving a support screw. The leg support section is bounded by the screw-support section and the leg section. The leg section is angulated with respect to the leg support section and has a degree of spring action that allows it to be compressed so as to allow it and the leg support section to be inserted between the respective lower portions of integrally-formed upstanding support arms of a support base. Once the screw retainer is completely inserted between the respective lower portions of the integrally- formed upstanding support arms, the leg section springs back to its normal position thereby preventing the screw retainer from becoming dislodged from its position.
