摘要： PURPOSE:To reduce sounds caused when the action of an electromagnetic relay is restored by providing a rubber damper which comprises a pair of cavity portions communicated with each other via a fluid passage or comprises each cavity portion and the fluid passage both filled with a liquid, and sandwiching a moveable contact spring between the cavity portions. CONSTITUTION:A low operating sound electromagnetic relay has a rubber damper 3 which comprises a pair of cavity portions 31 communicated with each other via a fluid passage 32 and a moveable contact spring 22 is sandwiched between the cavity portions 31 or each of the cavity portions 31 of the rubber damper 3 and the fluid passage 32 are both filled with a liquid 33. Until a moveable contact 2 is made to abut on each of arc side fixed contacts 23, 24, acceleration of an armature 14 is thereby restrained, reducing impulsive sounds caused when a moveable contact 21 abuts on each of the fixed contacts 23, 24 or the armature 14 collides with an electromagnet 13.

摘要： PURPOSE:To realize high contact capacity and low height in the title relay by using a plunger inserted movably in a hollow bobbin. CONSTITUTION:A solenoid coil 4 wound on a hollow bobbin 3, a plunger 5 inserted movable in the hollow bobbin 3, a permanent magnet 6 incorporated to the plunger 5 and magnetized in the axial direction, and a moval contact spring 21 opposing to the end surface of the plunger 5 are provided, and the movable contact spring 21 in which the movable contact 22 is fixed at the free end is driven by the plunger 5. Since there is no armature or no auxiliary yoke at the outer side of the solenoid coil 4, the height can be made low, and even though the current flowing to the solenoid coil is small, the relay can be operated sufficiently by the interaction with the permanent magnet 6, and the movable scope of the plunger can be also increased. Therefore, a low power consumption type electromagnetic relay with a high contact capacity and a low height can be realized.

摘要： PURPOSE:To lower working noise and vibrating noise leaking out of a lead plate to outside by covering an electromagnetic relay with an external case and at the same time composing an outside drawn lead with a flexible printed board. CONSTITUTION:A flexible printed circuit board 3 is connected to a main body of a relay 1. It is carried out by inserting terminals 11 into terminal insertion holes 31a and dip-soldering them collectively. When the main body 1 of the relay is inserted in a box 2 in the way of setting the terminals 11a to face up, vertical parts 32 of the printed circuit board 31 hang outside of the base box 2. Then, when the circuit board 3 is covered with a cover box 4 the vertical parts 32 of the circuit board 3 are pinched between the boxes 4, 2 and their end parts are to outside from the end rim 41 of the box 4 and become outside connection pads 31b.

摘要： PURPOSE:To prevent the damage of a reed switch when it is sealed with a resin and to enhance its productivity by filling a specific elastic resin between the glass tube region of the reed switch and a coil. CONSTITUTION:A reed switch 11 is inserted through a coil 12 and made to fall in a jig 13. Successively, a liquid-like elastic-made resin 17 which makes a rubber-like form at the time of being hardened is injected into a gap region between the one-side end surface of coil 12 and the reed switch 11 by an injector-like dispenser 16 and then dried. Therefore, a switching element 19 is obtained in which the elastic-made resin 17 is filled in a gap between the coil 12 and the reed switch 11. Thus, the elastic-made resin 17 is used for resin sealing, thereby preventing the damage of the glass tube of the reed switch 11 when it is sealed with a resin and enhancing its productivity.

摘要： PURPOSE:To reduce oscillation to be transmitted to an outer cover for reducing an operation sound by holding a relay body mounted on a printed board while floating it from the outer cover by using a lead terminal. CONSTITUTION:The subject electromagnetic relay is provided with an electromagnetic relay body 1, in which a plurality of terminals 11 housed in an inside case are upside projected, a printed board 2, in which the electromagnetic relay body 1 is downside mounted, a lead terminal 3 being connected to the printed board 2 and led out downside to hold the printed board 2 and a base member 4 which the lead terminal 3 goes through for being fixed while holding the electromagnetic relay body 1 through a gap. Further, a cover member 5 spreading over the base member 4 and surrounding the electromagnetic body 1 through a gap. Then, the relay body 1 is held inside an outer cover 5 in the hanged state floating from the outer cover 5 so that the oscillation of the relay body 1 may almost not conveyed to the outer cover 5. In this way, contact with the outer case and a lead plate can reduce an oscillation sound leaking to the outside.
