Flat plate type thyristor

Abstract

The utility model provides a flat plate type thyristor, relates to the technical field of thyristors, and aims to solve the problems that the two sides of the conventional thyristor are sealed by glue to form an integrated structure, but the fixing mode is not favorable for heat dissipation, and the glue falls off in a high-temperature environment, so that the thyristor cannot be normally used, and the service life of the thyristor is influenced. The thyristor solves the problems that the existing thyristor is poor in heat dissipation performance, and the service life of the thyristor is shortened when the thyristor is used in a high-temperature state due to the fact that the thyristor is sealed into an integrated structure by glue and heat generated by the thyristor in use cannot be dissipated, and comprises mounting components. After the cathode block and the anode block are installed in the shell, the locking ring covers the outer ends of the cathode block and the anode block, then the limiting block is inserted into the locking groove, and the notch and the limiting block are staggered by rotating the locking ring, so that the cathode block and the anode block can be limited and fixed, and the fixing has the advantage that the influence caused by high temperature generated in the thyristor is avoided.

Description

Technical Field

[0001] The utility model belongs to the technical field of thyristors, and more specifically, particularly relates to a flat thyristor. Background Art

[0002] Thyristor is a high-power semiconductor device developed on the basis of transistor. The emergence of thyristor has expanded semiconductor devices from the weak current field to the strong current field. Thyristor contains anode, cathode and gate; thyristor can work under high voltage and high current conditions, and has been widely used in electronic circuits such as controlled rectification, AC voltage regulation, contactless electronic switch, inverter and frequency conversion. Based on the existing technology, it is found that the two sides of the existing thyristor are sealed with glue to make it an integrated structure, but this fixing method is not conducive to heat dissipation. The high temperature environment brought about will cause the glue to fall off, resulting in the thyristor being unable to be used normally. In addition, the existing thyristor has poor heat dissipation. Since the thyristor is sealed into an integrated structure with glue, the heat generated during use cannot be dissipated. Such long-term use in high temperature conditions will shorten the service life of the thyristor. Utility Model Content
