Description

Technical Field

[0001] This utility model relates to the field of transistor technology, and in particular to an isolation structure for a field-effect transistor. Background Technology

[0002] Field-effect transistors are voltage-controlled devices that need to be mounted on a carrier for use. However, the carrier usually has many other components on it. Therefore, when the transistor is mounted close to heat-generating components, it is easily damaged by heat.

[0003] A search revealed that utility model patent CN220233167U discloses a silicon carbide-based power field-effect transistor, comprising a transistor, a first mounting plate fixedly connected to one side of the transistor, and second mounting plates fixedly connected to both the left and right sides of the other side of the transistor. Both the first and second mounting plates have first mounting holes inside. Sliding grooves are formed on both the left and right sides of the first mounting plate, and sliding plates are slidably connected inside the sliding grooves. A first connecting plate is fixedly connected to one side of the sliding plate.

[0004] However, the aforementioned field-effect transistors still have some drawbacks in practical use. The most obvious one is that when installing them on the heat-insulating frame, the operator needs to slide the frame to move the slide plate into the inner side of the groove to connect the frame and the transistor. However, because the slide plate is small and the frame will block the opening of the groove during the sliding process, the operator cannot accurately observe the position of the groove opening. Therefore, the operator often cannot easily slide the slide plate into the inner side of the groove, which is quite inconvenient in actual use.

[0005] Therefore, it is necessary to invent an isolation structure for field-effect transistors to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an isolation structure for field-effect transistors, which allows for more convenient installation of the isolation components and eliminates the need for subsequent screw reinforcement, making it more convenient in actual use. This addresses the problem mentioned in the background art where, when installing a heat-insulating frame plate, the operator needs to slide the frame plate to move the slide plate into the inner side of the groove to connect the frame plate and the transistor. However, due to the small size of the slide plate and the obstruction of the groove opening during frame plate sliding, the operator cannot accurately observe the opening position of the groove. Therefore, the operator often cannot easily slide the slide plate into the inner side of the groove, which is inconvenient in actual use.

[0007] According to one aspect of this disclosure, the following technical solution is provided: an isolation structure for a field-effect transistor, comprising:

[0008] Field-effect transistor components;

[0009] An isolation component for isolating heat; and

[0010] A quick-locking mechanism, comprising a U-shaped frame, a locking rod, a return spring, and a lever;

[0011] The U-shaped frame is fixedly installed on the top of the second mounting plate. The locking rod is installed through the side of the U-shaped frame and has an inclined surface at its inner end. The reset spring is sleeved on the outside of the locking rod and fixedly connected between the outer wall of the U-shaped frame and the lever plate. The lever plate is fixedly installed at the outer end of the locking rod.

[0012] According to at least one embodiment of the isolation structure of the field-effect transistor of the present disclosure, the field-effect transistor assembly includes a transistor body and a first mounting plate, wherein two first mounting plates are provided, and the two first mounting plates are respectively fixedly disposed on both sides of the transistor body.

[0013] According to at least one embodiment of the isolation structure of the field-effect transistor of the present disclosure, the field-effect transistor assembly further includes a second mounting plate and mounting holes. The second mounting plate is fixedly disposed at the rear end of the transistor body, and three mounting holes are provided, which are respectively opened on the top of the second mounting plate and the two first mounting plates.

[0014] According to at least one embodiment of the field-effect transistor isolation structure of the present disclosure, the isolation component includes a heat insulation frame, and clearance grooves are provided on both sides of the front end and the rear end of the heat insulation frame.

[0015] According to at least one embodiment of the field-effect transistor isolation structure of the present disclosure, the isolation component further includes a fixing block and a locking groove, the fixing block being fixedly disposed at the rear end of the heat insulation frame, and the locking groove being formed on the side of the fixing block.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] This invention features a quick-locking mechanism. After the heat insulation frame is vertically fitted onto the outside of the transistor body, the fixing block descends synchronously with the heat insulation frame. During this process, the bottom end of the fixing block pushes the locking rod through the inclined surface of the inner end of the locking rod, causing the locking rod to move outward to avoid obstruction. As the locking rod moves outward, a lever stretches the return spring. After the heat insulation frame is installed in place, the locking rod and the locking groove are collinear. At this point, the stretched return spring pushes the locking rod through the lever, causing the inner end of the locking rod to enter the inner side of the locking groove to complete the locking. Compared to existing similar products, this invention allows for more convenient installation of the isolation component, and eliminates the need for subsequent screw reinforcement, making it more convenient in actual use.

[0026] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0028] Figure 2 This is a schematic diagram of the isolation structure of a field-effect transistor assembly 1 and a quick-locking mechanism 3 according to one embodiment of the present disclosure.

[0029] Figure 3 This is a schematic diagram of the isolation component 2 of the isolation structure of a field-effect transistor according to one embodiment of the present disclosure.

[0030] like Figures 1-3 As shown, the isolation structure of the field-effect transistor disclosed herein may include components such as: field-effect transistor assembly 1, isolation assembly 2, and quick-locking mechanism 3.

[0031] like Figure 2 As shown in this disclosure, the field-effect transistor assembly 1 includes a transistor body 11, a first mounting plate 12, a second mounting plate 13, and mounting holes 14. There are two first mounting plates 12, which are respectively fixedly disposed on both sides of the transistor body 11. The second mounting plate 13 is fixedly disposed on the rear end of the transistor body 11. There are three mounting holes 14, which are respectively opened on the top of the second mounting plate 13 and the two first mounting plates 12.

[0032] This allows the transistor body 11 to be fixed to the carrier by using screws through the three mounting holes 14, thus completing the installation of the transistor body 11.

[0033] like Figure 3 As shown, in a preferred embodiment, the isolation component 2 includes a heat insulation frame 21, a fixing block 22, and a locking groove 23. The heat insulation frame 21 has clearance grooves on both sides of the front end and the rear end. The fixing block 22 is fixedly disposed at the rear end of the heat insulation frame 21, and the locking groove 23 is disposed on the side of the fixing block 22.

[0034] Therefore, after the heat insulation frame 21 is fitted onto the outside of the transistor body 11, it can isolate the heat around the transistor body 11, thereby reducing the impact of heat on the transistor body 11.

[0035] like Figure 2 As shown in this disclosure, the quick locking mechanism 3 includes a U-shaped frame 31, a locking rod 32, a return spring 33, and a lever 34. The U-shaped frame 31 is fixedly mounted on the top of the second mounting plate 13. The locking rod 32 passes through the side of the U-shaped frame 31 and has an inclined surface at its inner end. The return spring 33 is sleeved on the outside of the locking rod 32 and fixedly connected between the outer wall of the U-shaped frame 31 and the lever 34. The lever 34 is fixedly mounted on the outer end of the locking rod 32.

[0036] Therefore, after the heat insulation frame 21 is vertically fitted onto the outside of the transistor body 11, the fixing block 22 descends synchronously with the heat insulation frame 21. During this process, the bottom end of the fixing block 22 pushes the locking rod 32 through the inclined surface of the inner end of the locking rod 32, thereby causing the locking rod 32 to move outward to avoid obstruction. During the outward movement of the locking rod 32, the return spring 33 is stretched by the lever 34. After the heat insulation frame 21 is installed in place, the locking rod 32 and the locking groove 23 are collinear. At this time, the stretched return spring 33 pushes the locking rod 32 through the lever 34, thereby causing the inner end of the locking rod 32 to enter the inner side of the locking groove 23 to complete the locking. Compared with existing similar products, the installation operation of the isolation component 2 can be completed more conveniently, and there is no need to use screws for reinforcement afterward, making it more convenient in actual use.

[0037] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0038] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
