Abstract

838,823. Electromagnetic relays. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 25, 1957 [Oct. 25, 1956], No. 32525/56. Class 38 (5). [Also in Group XXXV] Relay coils 4 on non-porous bobbins 5 are enclosed in a canister 22 which is hermetically sealed to the ends of the bobbins 5 by tinning the bobbin and canister and then heating them together, and the canister may be filled with resin 3 before sealing. The U-shaped magnetic core 2 has its centre portion embedded in a massive base of magnetic material, which may act as a " heat sink " for the relay, and its ends pass through holes in the canister and bobbins into a second sealed compartment 20 containing the armature 8 with contacts on an insulating member 12, polarizing magnet 10 and fixed contacts 16. The whole relay is enclosed in a further sealed canister 24.
