Abstract

The invention relates to the technical field of intelligent electronics, and discloses a dry reed electromagnetic relay. The relay comprises a tube body, the two acting ends of the tube body are fixedly connected with leads, the other ends of the leads are fixedly connected with a conductive shell, the interior of the conductive shell is slidably connected with a baffle, and the left side of the baffle is fixedly connected with a supporting rod. The other end of the supporting rod is fixedly connected with a sliding block. The reed is arranged in the conductive shell, so that a bent area is located in a pin tube body when deflection occurs, damage to the tube body caused by deflection of a lead and the reed is effectively eliminated, meanwhile, automatic switching of two working modes is achieved through heating expansion of gas on the right side of the conductive shell, and the long-time continuous electrifying effect is achieved; and meanwhile, the effect of disconnecting an external magnetic field and quickly disconnecting the reed switch during long-time continuous work is realized through the matched arrangement of the sliding block, the iron core and the coil, and the problem of slow contact disconnection caused by long-time continuous work of the reed switch in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of intelligent electronics, in particular to a reed electromagnetic relay. Background technique [0002] The dry reed switch was invented in 1936 and has a history of nearly a hundred years. Due to the special physical and chemical properties of the reed, it has a high natural frequency. When in use, the contact point is very fast, and the switching speed is 5-10 times faster than that of the general electromagnetic relay block. It is widely used in home appliances, automobiles, communications, medical care, security and other fields. In addition, it can also be widely used in the manufacture of new sensors and high-end electronic devices, which has great strategic significance in the future development of science and technology. [0003] The reed switch realizes the deflection of the reed by applying an external magnetic field to polarize the reed and then realizes the switch effect. During the polarization...
