Bidirectional trigger diode chip

Abstract

The invention discloses a bidirectional trigger diode chip, comprising a casing, wherein an upper surface and a lower surface of a right side of an inner side wall of the casing are respectively fixedly connected to sides of two mounting shells away from each other, the lower surface of the inner side wall of each mounting shell is fixedly connected to the bottom of a spring, the top of the mounting shell is snapped with a sliding sleeve, the top of the spring is fixedly connected with the lower surface of a limiting plate, the upper surface of the limiting plate is fixedly connected with thebottom of a connecting rod, and the top of the connecting rod penetrates through the sliding sleeve and extends out of the mounting shell. When a chip body of the bidirectional triggering diode chip provided with the mounting shells, the springs, the limiting plates, the sliding sleeves, the connecting rods and clamping blocks is mounted and detached, two dialing plates only need to be moved up and down, so that the chip body and a circuit board are prevented from being damaged by squeezing or touching the chip body during replacement, unnecessary trouble is reduced, and the chip body is moreconvenient to replace.

Description

technical field [0001] The invention relates to the technical field of diodes, in particular to a bidirectional trigger diode chip. Background technique [0002] Bidirectional trigger diode, also known as two-terminal AC device, came out at the same time as bidirectional thyristor. Because of its simple structure and low price, it is often used to trigger bidirectional thyristor, and it can also form circuits such as overvoltage protection. The structure, symbol and equivalent circuit of a bidirectional trigger diode. [0003] In various circuit experiments, bidirectional trigger diode chips will be used. For example, a Chinese patent discloses "a diode that is easy to install and disassemble" (patent number: CN 206301806 U). The technological process reduces environmental pollution and enables the diode to be recycled to avoid waste of resources. However, during the installation process, the pressure rod is pressed by hand to make the pressure rod fit with the conical hole...
