Abstract

DC60 (21/04/41) The purpose of this invention is to provide an electromagnetic relay with reduced heat transfer between the electromagnetic housing and the contacts, and a low-resistance electrical circuit. In this relay, the movable contact terminal is attached to the yoke by a protruding piece from the flat base that acts as a baffle to reduce heat transfer along the housing as in the first design of this invention. The relay may have a movable contact terminal and a movable folding spring attached to the yoke of the electromagnetic housing. This folding spring is electrically connected directly to the movable contact terminal attached to the yoke to reduce electrical resistance. Therefore, this type of relay is not electrically connected directly to the yoke like the first invention. The purpose of this invention is to provide an electromagnetic relay with reduced heat transfer between the electromagnetic housing and the contacts, and a low-resistance electrical circuit. In this relay, the movable contact terminal is attached to the yoke by a protruding piece from the flat base that acts as a baffle to reduce heat transfer along the housing as in the first design of this invention. The relay may have a movable contact terminal and a movable folding spring. Attached to the yoke of the magnetic box, the aforementioned folding spring is electrically connected directly to the movable contact terminals attached to the yoke to reduce electrical resistance. Therefore, this type of relay is not electrically connected directly to the yoke like the first invention.
