发明名称 Relay with restricted guidance contacts
摘要 In a miniaturized relay for explosion endangered regions, the coil, core, and yoke are cast integrally into the carrier part. Restricted guidance contact units are disposed on the carrier part, on both sides of a partition. The armature is disposed on the side of the coil remote from contacts. A comb connects the armature on the one side of the coil body with the contact springs on the other side of the coil body. In the region in which the comb passes by the coil body, a guide for the comb is embodied on the carrier part. The partition has an extension which reaches into this guide region next to the coil. This extension and the rest of the partition are provided with a groove into which a rib on the cap encompassing the relay protrudes in order to elongate the air and leakage path between the contact units on the one side of the partition and the contact units on the other side of the partition. Air and leakage paths of at least 10 mm are maintained between the contacts and the electrically conductive parts of the magnetic circuit. A double insulation is provided between the contacts on the one side of the partition and those on the other.
