Abstract

A separating and arc shielding device is composed of a sliding part, an elastic metal piece and a spring. The sliding part is composed of a sliding block, a spring containing cylinder, an arc shielding cavity, a supporting strip and an auxiliary separating plate, wherein the spring containing cylinder is located on the sliding block; the arc shielding cavity is located in the closed end of the spring containing cylinder; the supporting strip is connected with the bottom surface of the arc shielding cavity; the auxiliary separating plate is located on the spring containing cylinder and the top surface of the arc shielding cavity. When the separating and arc shielding device is used, the spring is installed in a hole of the spring containing cylinder, one end of the spring makes contact with the wall of the spring containing cylinder, and the other end of the spring makes contact with a device using the separating and arc shielding device; the fixed head of the elastic metal piece is installed on the device using the separating and arc shielding device, the welding contact surface of the elastic metal piece is welded to an electrode or an electrode pin in the device using the separating and arc shielding device, and a connecting arm of the elastic metal piece is placed on the top surface of the auxiliary separating plate. A small-size high-safety all-mode protection surge protection device comprises an outer shell, a box used for installation of electron components, an overvoltage protection element set, the separating and arc shielding device and an arc extinction device.

Description

technical field [0001] The invention belongs to a protection device for electronic and electric equipment, in particular to a breakaway and arc shielding device and a surge protector. Background technique [0002] With the development of industries such as electric power and communication, the application range of surge protectors is becoming wider and wider, and the number of failures in applications is increasing. When the surge protector is degraded or overloaded, if it cannot be safely separated from the AC or DC circuit and equipment in time, accidents such as fire will occur. Therefore, the safety of the surge protector under the condition of deterioration or overload has attracted more and more attention. [0003] Chinese patent CN 201320177720.6 discloses a high-safety surge protector, including at least one overvoltage protection element located in the housing, a disconnecting device for separating the overvoltage protection element from the AC circuit or DC circuit...
