  • Patent number: 6448877
    Abstract: An electromagnetic relay has a reduced height while maintaining a good voltage withstand. A base unit includes a metal plate member and a base mold made of a plastic, the metal plate member having a break fixed contact point and a break terminal and being insertion-molded with the base mold. A subassembly, including an electromagnet assembly and a movable leaf spring/armature assembly attached to the electromagnet assembly, is fixed to an upper side of the base unit. The electromagnet assembly includes a bobbin, a coil, an iron core and a yoke. The movable leaf spring/armature assembly includes a movable leaf spring having a movable contact point and an armature fixed to the movable leaf spring. A make terminal member having a make fixed contact point and a make terminal is fixed to the base unit. The base mold has a yoke attaching part to which the yoke of the electromagnet assembly is attached and a make terminal member attaching part to which the make terminal member is attached.

  • Patent number: 5963116
    Abstract: A reed relay includes a reed switch with contacts, and a pair of terminals connected to the contacts. A tubular electrostatic shield defines an axially extending central bore within which the reed relay is inserted. A coil assembly has a winding drum, and a coil provided on the winding drum. The winding drum defines an axially extending central bore within which the electrostatic shield is inserted with the reed switch. A first pair of leads extend oppositely to each other, and are connected to the electrostatic shield at the opposite ends of the coil assembly. A second pair of leads extend oppositely to each other, and are connected to the electrostatic shield at the opposite ends of the coil assembly. A third pair of leads extend oppositely to each other, and are connected to the coil at the opposite ends of the coil assembly. A fourth pair of leads extend oppositely to each other, and are connected to the terminal of the reed switch at the opposite ends of the coil assembly.
