Description

Technical Field

[0001] The utility model relates to the technical field of electronic information, in particular to a single-tube IGBT which is easy to install. Background Art

[0002] The single-tube IGBT (insulated gate bipolar transistor) combines the high-speed switching characteristics of MOSFET with the high voltage and high current capabilities of bipolar transistors, making it a key component for high-efficiency power control in industries such as industry, transportation, and electricity. The single-tube IGBT is a common power semiconductor device that provides reliable and efficient switching control solutions for different electronic and power applications through a specific packaging form.

[0003] After searching, the patent number "CN218957714U" mentioned in the text that "the utility model discloses a single-tube IGBT that is easy to install, belonging to the field of single-tube installation technology, which includes a single-tube IGBT, the single-tube IGBT is provided with a threaded opening that is compatible with the thread of the screw, the top of the screw is fixedly connected with a column tooth, the column tooth is meshingly connected with a gear rod, the gear rod is fixedly connected with an elastic limiting structure, the elastic limiting structure is engaged with one of the two positioning openings provided on the connecting strip, and the connecting strip is fixedly connected with a guide strip on one side close to the gear rod". When in use, the single-tube IGBT that is easy to install, by setting the elastic limiting structure, the gear rod and the column tooth, is in contact with the gear rod. When installing a single-tube IGBT, the gear rod is moved to drive the column teeth to rotate, so that the column teeth drive the screw rod downward to pass through the threaded opening and connect with the installation part through thread locking. This method does not require the use of a screwdriver for disassembly and assembly, so that the installation and disassembly of the single-tube IGBT can be completed by directly and elastically twisting the structure. However, during the use of the single-tube IGBT, most of them are fixed by soldering and thread, and the fixing method is relatively simple, which makes it more troublesome to install different single tubes. At the same time, during the use of the single tube, since it needs to be over-powered, a certain amount of heat will be generated during the over-powering process due to its own characteristics. If it is not discharged in time, it is easy to cause overheating in a hot environment.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] See also Figure 1-4 As shown, the utility model provides a technical solution: a single-tube IGBT that is easy to install, comprising a single-tube IGBT body 1 and a single-tube body fixing mechanism 2, wherein the single-tube body fixing mechanism 2 is installed on the outer side of the single-tube IGBT body 1;

[0026] The single tube fixing mechanism 2 includes a single tube mounting assembly 21, a single tube protection assembly 22 and a heat dissipation assembly 23. The single tube mounting assembly 21 is arranged on the outer side of the single tube IGBT body 1, the single tube protection assembly 22 is installed on the inner side of the single tube IGBT body 1, and the heat dissipation assembly 23 is installed on the upper side of the single tube IGBT body 1.

[0027] Furthermore, the single-tube body mounting assembly 21 includes a threaded mounting hole 211, a rubber adhesive 212 and a resistive coating 213. A threaded mounting hole 211 is provided inside the left side of the single-tube IGBT body 1, and rubber adhesive 212 is installed on the lower side of the single-tube IGBT body 1. A resistive coating 213 is provided in the middle of the rubber adhesive 212. When needed, the resistive coating 213 can block the weak electric arc carried by the circuit board itself, thereby preventing the internal IGBT chip 221 from being damaged due to the influence of the electric arc.

[0028] Furthermore, the rubber adhesive 212 and the single-tube IGBT body 1 are adhesively connected, and the rubber adhesive 212 and the single-tube IGBT body 1 are symmetrically arranged on the left and right. When needed, the rubber adhesive 212 can be used to adhere and fix the single-tube IGBT body 1 without using screws, so that the single-tube IGBT body 1 is tightly connected to the circuit board, thereby achieving the effect of convenient installation.

[0029] Furthermore, the single-tube protection component 22 includes an IGBT chip 221, a heat-absorbing copper plate 222, thermal grease 223, a resistor fuse 224 and a conductive plate 225. The inner side of the single-tube IGBT body 1 is bonded with the IGBT chip 221, the upper side of the IGBT chip 221 is bonded with the heat-absorbing copper plate 222, and the upper side of the heat-absorbing copper plate 222 is bonded with the thermal grease 223. When it is needed, the heat generated by the IGBT chip 221 is absorbed by the heat-absorbing copper plate 222 and then dissipated by the thermal grease 223, which can effectively reduce the accumulation of heat and can dissipate the heat generated by the IGBT chip 221 in time to avoid damage to the IGBT chip 221.

[0030] Furthermore, a resistor fuse 224 is welded on the right side of the IGBT chip 221, and a conductive plate 225 is welded on the right side of the resistor fuse 224. When it is needed, when the resistance is too large, the resistor fuse 224 will melt by itself, thereby protecting the IGBT chip 221 and the circuit board from damage and protecting the body.

[0031] Furthermore, the heat dissipation assembly 23 includes a top cover 231 and a heat dissipation net 232. The top cover 231 is adhesively connected to the upper side of the single-tube IGBT body 1, and the heat dissipation net 232 is installed on the inner side of the top cover 231. When the thermal grease 223 absorbs heat, the heat dissipation net 232 can take out the heat generated by the thermal grease 223, thereby maintaining the overall heat within a suitable range.

[0032] Embodiment 2

[0033] See also Figure 1-4 As shown, compared with Example 1, as another implementation mode of the utility model, a pin fixing assembly 3 is installed on the right side of the single-tube IGBT body 1, and the pin fixing assembly 3 includes a single-tube body pin 31, a fixing frame 32, a resistance groove 33, a resistance button 34 and a clamping plate 35. The right side of the single-tube IGBT body 1 is welded with a single-tube body pin 31, a fixing frame 32 is installed on the upper side of the single-tube body pin 31, and a resistance groove 33 is installed on the inner side of the fixing frame 32. The inner side of the resistance groove 33 is connected to a resistance button 34 by a slot, and a clamping plate 35 is installed at the end of the resistance button 34. When it is needed, the fixing frame 32 can constrain the single-tube body pin 31 in the fixing frame 32, and then by pressing the resistance button 34 in the resistance groove 33, the resistance button 34 drives the clamping plate 35 to connect the single-tube body pin 31 with the electrode point to achieve the power-on effect, so that the connection can be made without soldering, avoiding the trouble of melting the tin again when maintenance is needed.

[0034] Furthermore, the splint 35 and the resistance button 34 are adhesively connected, and the splint 35 is made of soft rubber material. When it needs to be used, the rubber splint 35 uses the soft material to prevent the single tube pin 31 from short-circuiting due to conductivity problems, and can be adjusted according to the electrode point, making it more convenient to use.

[0035] Working principle: a single-tube IGBT that is easy to install is moved to the working position. When in use, the first step is to place the single-tube IGBT body 1 at the preset position of the circuit board, and then the rubber adhesive 212 is adhered to the circuit board by pressing, and the electric resistance coating 213 is used to isolate the arc, and then the threaded mounting hole 211 is used for additional fixation. The second step is to align the single-tube body pin 31 with the electrode point on the circuit board. After confirmation, the fixing frame 32 is buckled on the single-tube body pin 31, and the fixing frame 32 is fixed with bolts, and then the user presses the resistance button 34 in the resistance slot 33 to The clamping plate 35 squeezes the single tube body pin 31 to fix the single tube body pin 31. In the third step, as it is used, the IGBT chip 221 starts to be used in conjunction with the circuit board. The current flows through the single tube body pin 31 and the conductive plate 225, and the resistor fuse 224, and finally flows into the IGBT chip 221. In the fourth step, as the IGBT chip 221 generates heat, the heat-absorbing copper plate 222 absorbs the heat, and then the heat is dissipated through the thermal grease 223, and then the heat is circulated by the heat dissipation net 232 in the top cover 231. In this way, the use process of a single-tube IGBT that is easy to install is completed.
