Plastic packaged safety triode

Abstract

The invention discloses a plastic packaged safety triode, which comprises a connector, pins, a protection tube, a protection ring, a bottom plate, a triode body, a first limiting plate, a first anti-abrasion pad, a first clamping block, a first heat dissipation strip, a heat dissipation groove, a first arc-shaped plate, a mounting plate, a first arc-shaped ring, a first clamping groove, a top cover, a top plate, a limiting pad, a fixing ring, an anti-abrasion ring, a second clamping groove, a second arc-shaped ring, a second clamping block, a second arc-shaped plate, a second anti-abrasion pad, a second limiting plate, a mounting hole, a second heat dissipation strip, a heat dissipation column, a heat dissipation rod, a heat dissipation plate and a plastic packaging film. According to the triode, the plastic packaging film is arranged outside the triode body, so that the triode body can be protected, damage to the triode body caused by direct contact friction between other objects and the triode body is avoided, and installation and use of the triode are facilitated; and the triode body is positioned between the top cover and the bottom plate by using the mounted top cover, so that the triode body can be conveniently disassembled and assembled, and the mounting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of triodes, in particular to a plastic-encapsulated safety type triode. Background technique [0002] The triode is a semiconductor device that controls current. Its function is to amplify weak signals into electrical signals with large amplitudes. It is also used as a non-contact switch; it is one of the basic components of semiconductors and the core component of electronic circuits. The triode is made on a semiconductor substrate with two PN junctions that are very close to each other. The two PN junctions divide the whole semiconductor into three parts. The middle part is the base area, and the two sides are the emitter area and the collector area. The arrangement is PNP In our daily life, triodes often appear in the electronic products we use, but the existing triodes are not plastic-encapsulated during the preparation process, which may easily cause other objects to directly contact the triodes.

The triode is made on a semiconductor substrate with two PN junctions that are very close to each other. The two PN junctions divide the whole semiconductor into three parts. The middle part is the base area, and the two sides are the emitter area and the collector area. The arrangement is PNP In our daily life, triodes often appear in the electronic products we use, but the existing triodes are not plastic-encapsulated during the preparation process, which may easily cause other objects to directly contact the triodes. friction, which is not conducive to the protection of the triode, and is not conducive to the safe use of the triode. At the same time, during the installation process, the installation steps of the triode are cumbersome, which reduces the installation efficiency
