Description

Technical Field

[0001] The utility model belongs to the technical field of semiconductors, and in particular relates to an ultra-high voltage device structure. Background Art

[0002] High voltage devices refer to devices that can withstand voltages exceeding the normal range. These devices usually have special structures and designs to adapt to high voltages and currents. Common ultra-high voltage devices include thin film transistors, insulated gate bipolar transistors, static induction transistors, and metal oxide semiconductor field effect transistors. Therefore, it can be seen that existing semiconductors basically meet people's practical needs, but the following problems still exist.

[0003] When an operator is using an ultra-high voltage device, the operator connects the connecting pins and the circuit board to each other, so that the ultra-high voltage device can be used in the circuit board. Since the general connecting pins are relatively soft and easily bent by external force, the operator may straighten the connecting pins at once during use. When the operator straightens the connecting pins, the operator may use too much force, which may cause the connecting pin to break. In addition, since the general connecting pins may be fixed on the ultra-high voltage device, the connecting pins may not be able to be reinstalled. For this reason, we propose an ultra-high voltage device structure. Utility Model Content

[0008] Furthermore, the two groups of protective sleeves are fitted together to form a rectangular block, and the middle part of the traction plate is provided with a rectangular through hole that matches the rectangular block formed by the combination of the two groups of protective sleeves.

[0009] Furthermore, a slider is fixed on one side of the pull plate and the component body, and the surface of the slider is sleeved with a slide groove opened on the component body, and the inside of the slide groove is provided with a second spring respectively abutting between the inner wall of the slide groove and the surface of the slider.

[0012] 1.

When the operator needs to replace the contact point 3, the operator first pulls the protective cover 4, and the protective cover 4 drives the pull plate 8 to move, so that the pull plate 8 drives the slider 16 to slide in the slide groove 14. When the slider 16 slides in the slide groove 14, the slider 16 squeezes the second spring 15, causing the second spring 15 to undergo elastic deformation. After the second spring 15 undergoes elastic deformation, the second spring 15 presses the slider 16. To avoid, the slider 16 can slide in the slide groove 14, so that the pull plate 8 can slide on the surface of the component body 1. When the pull plate 8 slides on the surface of the component body 1, the pull plate 8 drives the protective cover 4 to move, so that the protective cover 4 is moved out from the surface of the connection interface 2, and when the protective cover 4 moves, the protective cover 4 drives the positioning rod 6 to move, so that the positioning rod 6 drives the positioning block 12 to move out of the positioning groove 7, so that the positioning rod 6 is separated, thereby separating the two groups of protective covers 4, and then the operator takes the contact point 3. After the contact point 3 is moved out of the surface of the positioning rod 6, the operator takes the new contact point 3 again, sets the new contact point 3 on the surface of the contact point 3, and then the operator releases the protective cover 4. After the protective sleeve 4 no longer squeezes the slider 16 on the second spring 15 through the pull plate 8, the second spring 15 recovers its elastic deformation, and the second spring 15 pushes the slider 16 to move. The slider 16 drives the protective sleeve 4 to move through the pull plate 8, and the protective sleeve 4 drives the positioning rod 6 to move, and the positioning rod 6 is inserted into the through hole opened on the surface of the contact point 3, and the positioning rod 6 drives the positioning block 12 to be inserted into the positioning groove 7, and the two groups of positioning rods 6 are connected together, so that the protective sleeve 4 is clamped on the connection interface 2 and the contact point 3 surface, and the contact point 3 is installed on the end of the connection interface 2, which is convenient for the operator to replace the contact point 3, and improves the convenience of the operator to replace the contact point 3.

[0026] In other embodiments, the surfaces of the two groups of protective sleeves 4 are sleeved with traction plates 5, and the traction plates 5 are connected to the opposite side of the component body 1 through an elastic member. The traction plates 5 are hot-melt-bonded with a plurality of groups of sleeve rods 11 on the side close to the component body 1, and the surfaces of the sleeve rods 11 are sleeved with sleeves 9 hot-melt-bonded to the surface of the component body 1, and the surfaces of the sleeve rods 11 are all wrapped with first springs 10, and the two side ends of the first springs 10 are respectively abutted between the inner wall of the sleeve 9 and the surface of the sleeve rod 11. When the operator needs to open the protective sleeve 4, the operator first pulls the traction plate 5, and the traction plate 5 drives the sleeve rod 11 to slide in the sleeve 9. When the sleeve rod 11 slides in the sleeve 9, the sleeve rod 11 squeezes the first spring 10, causing the first spring 10 to undergo elastic deformation. After the first spring 10 undergoes elastic deformation, the first spring 10 is The sleeve rod 11 avoids, so that the sleeve rod 11 moves out of the sleeve tube 9, and the traction plate 5 moves out from the surface of the protective sleeve 4. After the traction plate 5 no longer restricts the protective sleeve 4, the operator moves the two groups of protective sleeves 4 out from the surface of the connection interface 2. Then the operator replaces the contact point 3. After the two groups of protective sleeves 4 are fitted together again, the operator releases the traction plate 5. After the traction plate 5 no longer squeezes the first spring 10 through the sleeve rod 11, the elastic deformation of the first spring 10 is restored, and the first spring 10 drives the sleeve rod 11 to move in the sleeve tube 9, so that the sleeve rod 11 drives the traction plate 5 to move, and the traction plate 5 is sleeved on the surface of the protective sleeve 4. After the traction plate 5 is sleeved on the surface of the protective sleeve 4, the traction plate 5 restricts the two groups of protective sleeves 4, thereby increasing the stability of the traction plate 5 sleeved on the protective sleeve 4.

[0027] In other embodiments, two groups of protective sleeves 4 are fitted together to form a rectangular block, and a rectangular through hole matching the rectangular block formed by the two groups of protective sleeves 4 is opened in the middle of the traction plate 5. The rectangular block formed by the protective sleeves 4 fitting together matches the rectangular notch opened in the middle of the traction plate 5, so that the rectangular notch opened in the middle of the traction plate 5 can be sleeved on the surface of the rectangular block formed by the protective sleeves 4 fitting together, and the surface of the protective sleeve 4 fits with the inner wall of the rectangular notch opened in the middle of the traction plate 5, thereby increasing the stability of the rectangular notch opened on the surface of the traction plate 5 being sleeved on the surface of the protective sleeve 4.

When the slider 16 slides in the slide groove 14, the slider 16 squeezes the second spring 15, causing the second spring 15 to undergo elastic deformation. After the second spring 15 undergoes elastic deformation, the second spring 15 avoids the slider 16, so that the pull plate 8 It can slide on the surface of the component body 1. When the pull plate 8 slides on the surface of the component body 1, the pull plate 8 drives the protective cover 4 to move, so that the protective cover 4 is removed from the surface of the connection interface 2. When the operator releases the protective cover 4, the protective cover 4 no longer squeezes the second spring 15 through the pull plate 8, and the second spring 15 recovers its elastic deformation.

When the operator pulls the pull plate 8 to move, the operator first pulls the supporting plate 21, so that the supporting plate 21 drives the avoidance block 20 set as a semicircular shape to move in the avoidance groove 19 set as a semicircular groove. When the avoidance block 20 moves in the avoidance groove 19, the surface of the avoidance block 20 abuts against the inner wall of the avoidance groove 19 , so that the inner wall of the avoidance groove 19 squeezes the avoidance block 20, and the avoidance block 20 avoids the avoidance groove 19, so that the avoidance block 20 moves out of the avoidance groove 19. When the avoidance block 20 moves out of the avoidance groove 19, the avoidance block 20 and the avoidance groove 19 no longer restrict the support plate 21. The operator pulls the support plate 21, and the circular through hole opened at the end of the support plate 21 rotates on the surface of the cylindrical rotating shaft 13, and moves the support plate 21 out of the storage groove 18, so that the support plate 21 is erected in the storage groove 18. Then the operator pulls the support plate 21, and the support plate 21 drives the storage groove 18 to move through the rotating shaft 13, and the storage groove 18 drives the pull plate 8 to move through the fixed block 17, which is convenient for the operator to pull the pull plate 8 to move on the surface of the component body 1.
