Description

Technical Field

[0001] This invention belongs to the field of semiconductor technology, specifically relating to an integrated trench Schottky MOSFET. Background Technology

[0002] An integrated trench Schottky diode is a special type of semiconductor device that combines the characteristics of a trench structure and a Schottky diode. A MOSFET, or metal-oxide-semiconductor field-effect transistor, is a semiconductor device widely used in electronic circuits. MOSFETs belong to the insulated-gate type of field-effect transistor, and their gate is isolated by an insulating layer (usually oxide), hence they are often called insulated-gate field-effect transistors. They use the electric field effect of the control input circuit to control the output circuit current, and have characteristics such as high input impedance, low output impedance, high voltage control capability, and low power consumption.

[0003] Existing integrated trench Schottky MOSFETs are typically encapsulated in a housing, which is usually secured with screws. When internal maintenance is required, maintenance personnel need to unscrew and remove each screw, which takes time and effort. Therefore, we need to upgrade and modify the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide an integrated trench Schottky MOSFET to solve the problems mentioned in the background art.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] Design an integrated trench Schottky MOSFET, including a device body containing a lower housing and an upper cover at the front end of the lower housing. Both the lower housing and the upper cover have mounting slots, in which a chip is mounted. A mating clip is connected below the chip, and an L-shaped slot is engaged with the mating clip. Both the L-shaped slot and the mating clip have screw holes, and a pin is connected below the L-shaped slot. A bolt is screwed into the screw hole. A connecting clip is mounted on the outer wall of the lower housing, and a rotating shaft is fixed inside the upper cover.

[0007] Furthermore, the lower housing has a slot, and two sets of slots are symmetrically arranged. A buckle is movably engaged in the slot, and one end of the buckle is fixedly connected to the inner wall of the upper cover.

[0008] Furthermore, the upper cover shell has finger grooves inside, and two sets of finger grooves are symmetrically arranged with arc-shaped openings.

[0009] Furthermore, the L-shaped groove is provided with a countersunk groove, and multiple sets of countersunk grooves are provided, with bolts installed in the countersunk grooves.

[0010] Furthermore, the rotating shaft is installed inside the connecting buckle, and the rotating shaft is rotatably connected to the connecting buckle.

[0011] Furthermore, a hook is installed on the upper part of the lower housing, and a hanging hole is provided in the hook.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting a lower shell, an upper cover, a rotating shaft, a connecting buckle, a finger groove, a slot, a buckle, and a mounting groove, enables the device shell to be flipped and disassembled, making it convenient for users to inspect and maintain the inside of the device. This makes the replacement process simpler and faster, improves the flexibility and convenience of the device, and avoids the problem of traditional shell disassembly requiring the removal of screws one by one, which takes a lot of time.

[0014] 2. This utility model, by setting a mating buckle, L-shaped groove, screw hole, countersunk groove, bolt, and pin, enables the installation and fixation of the device pin, making it convenient for users to disassemble and replace it individually later, increasing the practicality and convenience of the device, and avoiding the trouble of inconvenient disassembly and replacement of the device.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 - Figure 5 As shown, this embodiment provides an integrated trench Schottky MOSFET, including a device body 1, a lower housing 2, an upper cover 3 at the front end of the lower housing 2, mounting slots 9 in both the lower housing 2 and the upper cover 3, a chip 10 in the mounting slots 9, a mating buckle 11 connected below the chip 10, an L-shaped buckle slot 12 snapped onto the mating buckle 11, screw holes 13 in both the L-shaped buckle slot 12 and the mating buckle 11, and a pin 17 connected below the L-shaped buckle slot 12, a bolt 16 screwed into the screw hole 13, a connecting buckle 5 installed on the outer wall of the lower housing 2, and a rotating shaft 4 fixedly installed inside the upper cover 3.

[0026] Preferably, the lower housing 2 has a slot 7, with two sets of slots symmetrically arranged. A buckle 8 is movably engaged in the slot 7, with one end of the buckle 8 fixedly connected to the inner wall of the upper housing 3. By setting the slot 7 and the buckle 8, the lower housing 2 and the upper housing 3 can be connected and fixed, ensuring the safety of the device during use and increasing the intimacy and connectivity between the devices. The upper housing 3 has a finger groove 6, with two sets of finger grooves symmetrically arranged and the opening of the finger groove 6 is arc-shaped. By setting the finger groove 6, it is convenient for the user to flip and adjust the upper housing 3, increasing the flexibility and practicality of the device and providing convenience for the user.

[0027] Preferably, the L-shaped groove 12 has a countersunk groove 14, and multiple sets of countersunk grooves 14 are provided. Bolts 16 are installed in the countersunk grooves 14. By setting the countersunk grooves 14, the bolts 16 can be stored, preventing the bolts 16 from being exposed outside the device during use and affecting the aesthetics of the device. The rotating shaft 4 is installed in the connecting buckle 5, and the rotating shaft 4 and the connecting buckle 5 are rotatably connected, which increases the connection and closeness between the devices and makes it convenient for users to adjust and control the device. A hook 18 is installed on the upper part of the lower housing 2. The hook 18 has a hanging hole 19. By setting the hook 18, it is convenient for users to install and fix the device, which increases the practicality and convenience of the device.

[0028] The working principle and operation process of this utility model are as follows: During use, the user places their finger in the finger groove 6, and then uses their other hand to pry the lower housing 2 off. During this process, the locking groove 7 of the lower housing 2 separates from the locking buckle 8 of the upper housing 3. After separation, the upper housing 3 flips to the other side. The user places the chip 10 to be installed in the mounting slot 9. After installation, the user rotates the upper housing 3 by hand. During rotation, the rotating shaft 4 rotates within the connecting buckle 5 until it flips over so that the upper housing 3 covers the chip 10 and the lower housing 2 (conversely, it can be disassembled). This allows for easy flipping and disassembly of the device's outer casing, facilitating internal inspection and maintenance. It also makes the replacement process simpler and faster, improving the device's flexibility. The device offers flexibility and convenience, avoiding the time-consuming process of disassembling screws one by one as required by traditional casing disassembly. When replacing the device pin 17, the user first opens the upper cover 3 and flips it to the other side of the lower cover 2. Then, using a tool, the user removes the bolt 16 from the countersunk groove 14 and screw hole 13 of the pin 17 to be replaced, until the bolt 16 is completely separated from the pin 17. After separation, the user can remove the pin 17 to be replaced from the mating buckle 11. After removal, the new pin 17 can be installed. This allows for the installation and fixation of the device pin 17, facilitating individual disassembly and replacement by the user later. This increases the practicality and convenience of the device and avoids the inconvenience of disassembling and replacing the device.
