[0002] Existing transistors are prone to internal short circuits that could lead to external explosions during use, and their complex installation structure makes them difficult to disassemble and maintain. A Chinese patent discloses a "packaged transistor" (application number CN201921999787.1), which features a simple structure, reducing both purchase and production costs, thus providing manufacturers with more favorable conditions. It also boasts higher heat dissipation efficiency and better heat dissipation, making it potentially widely applicable. However, this transistor still poses a risk of internal short circuits leading to external explosions, and its complex installation structure makes it difficult to repair and maintain. Utility Model Content

This makes the structure compact and stable, which is beneficial to the stable operation of the explosion-proof transistor.

[0008] Furthermore, the front ends of the first, second, and third insulating shells are all provided with rectangular through holes to facilitate the installation of metal conductors.

[0009] Furthermore, the front ends of the emitter, base, and collector are all fixedly connected to metal conductors, which are sleeved within rectangular through-holes and extend to the outside through these holes. This design makes the structure compact and stable, which is beneficial for the stable operation of the explosion-proof transistor.

[0010] Furthermore, the base is connected to the emitter via a first connector, and the base is connected to the collector via a second connector. This facilitates the normal operation of the explosion-proof transistor.

[0011] Furthermore, the first, second, and third insulating mounting plates are all provided with threaded mounting holes to facilitate bolt installation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1 , Figure 2 and Figure 4 An embodiment of this utility model provides an explosion-proof transistor, including an explosion-proof shell 1 made of polycarbonate. Inside the explosion-proof shell 1, from left to right, are fixedly connected a first insulating shell 15, a second insulating shell 13, and a third insulating shell 12. The second insulating shell 13 is fixedly connected to the first insulating shell 15 and the third insulating shell 12. The second insulating shell 13 is connected to the first insulating shell 15 via a first connector 17 and to the third insulating shell 12 via a second connector 18. The first insulating shell 15, the second insulating shell 13, and the first insulating shell 17 are sleeved together, and the second insulating shell 13, the third insulating shell 12, and the second insulating shell 12 are sleeved together. A rectangular through-hole 14 is provided at the front end of each of the first insulating shell 15, the second insulating shell 13, and the third insulating shell 12.

[0023] Specifically, during the use of explosion-proof transistors, the explosion-proof housing 1 serves as an explosion-proof protector, provides environmental isolation, dissipates heat, and provides electrical insulation. The explosion-proof housing 1 effectively prevents damage to the external environment from explosions or high-temperature gas leaks occurring inside the equipment. It can withstand internal pressure, preventing gas escape. Made of polycarbonate, the explosion-proof housing 1 has excellent corrosion resistance and oxidation resistance, enabling it to operate normally in harsh environments and extending its service life. The explosion-proof housing 1 provides good heat dissipation, keeping the transistor within a safe operating temperature range and preventing spontaneous combustion or explosion caused by overheating. It also provides electrical insulation, preventing short circuits or sparks caused by electrical accidents, while protecting internal electronic components.

[0024] Reference Figure 1 , Figure 3 and Figure 4 The system comprises an emitter 3, a base 6, and a collector 11. The emitter 3 is fitted inside a first insulating shell 15, and a first insulating mounting plate 4 is fixedly connected to the rear end of the emitter 3. The first insulating mounting plate 4 is fixedly connected to the explosion-proof shell 1 by a first bolt 5. The base 6 is fitted inside a second insulating shell 13, and a second insulating mounting plate 7 is fixedly connected to the rear end of the base 6. The second insulating mounting plate 7 is fixedly connected to the explosion-proof shell 1 by a second bolt 8. The collector 11 is fitted inside a third insulating shell 12, and a third insulating mounting plate 9 is fixedly connected to the rear end of the third insulating shell 12. The insulating mounting plate 9 is fixedly connected to the explosion-proof shell 1 by the third bolt 10. The front ends of the emitter 3, the base 6 and the collector 11 are all fixedly connected with metal conductors 2. The metal conductors 2 are sleeved with the rectangular through holes 14 and extend to the outside through the rectangular through holes 14. The base 6 is connected to the emitter 3 through the first connector 17 and to the collector 11 through the second connector 18. The first insulating mounting plate 4, the second insulating mounting plate 7 and the third insulating mounting plate 9 are all provided with threaded mounting holes 16. The second insulating mounting plate 7 abuts against the first insulating mounting plate 4 and the third insulating mounting plate 9.

[0025] Specifically, an NPN transistor is used. A small current, namely the base current, is applied between the emitter 3 and the base 6. This small current controls the larger current flowing from the emitter 3 to the collector 11. The current between the collector 11 and the base 6 is amplified by the base current. When an appropriate forward bias voltage is applied to the base 6, the transistor conducts, and the emitter current flows to the collector 11, producing an amplification effect. When the base current is zero, the transistor does not conduct, and the collector current is zero. When the base current reaches a certain value, the transistor is fully turned on, and the current from the collector 11 to the emitter 3 reaches its maximum value.

[0026] Working principle: This explosion-proof transistor uses an explosion-proof housing 1 made of polycarbonate, which provides explosion protection, environmental isolation, heat dissipation, and electrical insulation. During operation, when a suitable forward bias voltage is applied to the base 6, the transistor conducts, and the current from the emitter 3 flows to the collector 11, producing an amplification effect. When the current at the base 6 is zero, the transistor does not conduct, and the current at the collector 11 is zero. When the current at the base 6 reaches a certain value, the transistor conducts completely, and the current from the collector 11 to the emitter 3 reaches its maximum value. When repairing this explosion-proof transistor, the emitter 3, base 6, and collector 11 can be quickly disassembled from the inside, facilitating the replacement of electronic components.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
