DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-5 This application is described in further detail.

[0019] The embodiment of the present application discloses a vertical same-direction rectifier bridge stack. Figure 1-Figure 5 A vertical co-directional rectifier bridge stack includes a package body 1, a first DC pin 2, a second DC pin 3, a first AC pin 4 and a second AC pin 5 led out from the package body 1, and a first frame, a second frame, a third frame and a fourth frame are also provided in the package body 1. The first frame leads the first DC pin 2 from the inside of the package body 1, the fourth frame leads the second DC pin 3 from the inside of the package body 1, the second frame leads the first AC pin 4 from the inside of the package body 1, and the third frame leads the second AC pin 5 from the inside of the package body 1. The first DC pin 2, the second DC pin 3, the first AC pin 4 and the second AC pin 5 are arranged on the same side of the package body 1, the first DC pin 2 and the second DC pin 3 are distributed at the same end, and the first AC pin 4 and the second AC pin 5 are distributed at the other end.

[0020] When the first DC pin 2, the second DC pin 3, the first AC pin 4 and the second AC pin 5 need to be bent, a support structure for facilitating bending is provided on the outer wall of the package body 1. The support structure includes a bracket 6 slidably arranged on the outer wall of the package body 1, a support component for support, and a force-bearing component for applying a force. The support component is used to control the folding position at a position 3mm from the surface of the package body 1, and the force-bearing component is used to apply a force for the bending work. Of course, in this embodiment, the folding position can also be set above 3mm. In this embodiment, a bending position of 3mm is used for explanation.

[0021] The support assembly includes a support piece 7 and a rotating portion. The support piece 7 is rotatably connected to the bracket 6 via a rotating shaft, and the rotating axis is arranged horizontally. The rotating portion is used to lock the support piece 7 after rotation. The axis direction of the rotating shaft between the support piece 7 and the bracket 6 is parallel to the movement direction of the bracket 6, thereby facilitating the support piece 7 to bend toward the first DC pin 2, the second DC pin 3, the first AC pin 4, and the second AC pin 5. For simplicity of description in this embodiment, the first DC pin 2, the second DC pin 3, the first AC pin 4, and the second AC pin 5 are collectively referred to as pins. Based on the length of the support piece 7 and the distance between the bracket 6 and the pins, the position at which the top end of the support piece 7 abuts the pins after tilting is ensured to be 3 mm. The rotating portion is used to lock the position of the support piece 7, thereby ensuring that the support piece 7 can support the pins in their position when bending. Of course, in actual circumstances, the pins often bend in the direction of the bracket 6. Therefore, in this embodiment, only one bracket 6 is provided. Of course, a bracket 6 and a support piece 7 can also be provided on the other side of the pins to support bending of the support piece 7 in both directions.

[0022] Taking into account that the bending position of the pin is not only 3mm, it is necessary to adjust the length of the support piece 7. The support piece 7 also includes a bottom piece 30 and a telescopic piece 31. The telescopic piece 31 is movably arranged in the bottom piece 30. The bottom piece 30 is rotatably connected to the bracket 6. The bottom piece 30 is provided with a telescopic hole. Telescopic blocks 33 are provided on both sides of the telescopic piece 31. The bottom piece 30 is provided with adjustment grooves 32 on both sides of the telescopic hole. The telescopic blocks 33 are slidably arranged in the adjustment groove 32. A plurality of placement grooves 34 are provided on the inner wall of the adjustment groove 32. The plurality of placement grooves 34 are arranged at equal intervals in the adjustment groove 32 and the length direction of the placement groove 34 is perpendicular to the length direction of the adjustment groove 32. One end of the placement groove 34 is connected to the adjustment groove 32 The other end is closed, and the telescopic block 33 slides and fits in the telescopic hole. When the position of the telescopic piece 31 and the bottom film 30 needs to be adjusted, the telescopic piece 31 is controlled in the telescopic hole, and the telescopic block 33 moves in the adjustment slot 32. When the position of the telescopic piece 31 moves to the specified position, the telescopic block 33 is moved into the placement slot 34. The depth of the placement slot 34 is greater than the size of the telescopic block 33, and the placement slot 34 is set on the inclined side of the bottom film 30. When the telescopic block 33 is in the placement slot 34, the telescopic block 33 will not slide out of the placement slot 34 due to the pressure of the pin, thereby realizing the position adjustment of the telescopic piece 31, and the pin can be supported and bent at different positions.

[0023] The rotating part includes a rotating disk 8, a plug-in block 9, a driving column 10 and a torsion spring which are coaxially arranged with the rotating shaft. The support piece 7 is connected to the bracket 6 by a torsion spring. The rotating disk 8 is provided with a slide groove 14 along the radial direction of its cross-section circle. The plug-in block 9 is elastically arranged in the plug-in groove 11. The bracket 6 is provided with a plug-in hole 12. The plug-in block 9 is plugged into any plug-in hole 12. The driving column 10 is slidably set in the plug-in hole 12. The plug-in hole 12 is a through setting. When the plug-in block 9 is plugged into the plug-in hole 12, one end of the driving column 10 slides out of the plug-in hole 12. In this embodiment, the position of the telescopic piece 31 can be adjusted or the rotation angle of the bottom piece 30 can be adjusted to adjust the support position of the pin. It is preferably adjusted by adjusting the position of the telescopic piece 31. Therefore, only one plug-in hole 12 is required. The plug-in slot 11 is more convenient for the plug-in block 9 to move along the radial direction of the rotating disk 8. A spring 35 is fixedly connected between the end of the plug-in block 9 located in the plug-in slot 11 and the inner wall of the end of the plug-in slot 11. In the initial state, the plug-in block 9 abuts against the bracket 6, the plug-in block 9 is located in the slide groove 14, and the spring 35 is compressed and deformed. When the support piece 7 starts to be rotated, until the plug-in block 9 moves to the position of the plug-in hole 12, the plug-in block 9 is inserted into the plug-in hole 12, and one end of the drive column 10 is slid out of the plug-in hole 12. The length of the drive column 10 is equal to the length of the plug-in hole 12, and the drive column 10 will not slide out of the plug-in hole 12. After the plug-in block 9 is inserted into the plug-in hole 12, the position of the support piece 7 is locked, and at this time, the end of the support piece 7 is better abutted against the position where the pin is to be folded.

[0024] The bottom of the bracket 6 is provided with a slider 13, and the package body 1 is provided with a slide groove 14. The sections of the slider 13 and the slide groove 14 are both set to T-shaped. The slider 13 is provided with a slide cavity along the width direction of the slide groove 14. The slider 13 is provided with two ejector pins 15 in the slide cavity. The end of the ejector pin 15 is provided with a friction layer 36 for increasing friction. The slider 13 is also provided with a driving part for controlling the two ejector pins 15 to move outward. Since the slider 13 and the slide groove 14 are set to T-shaped in order to prevent the bracket 6 from sliding during the bending process, the slider 13 is mainly for the slider 1. 3 is limited in the vertical direction, and the bracket 6 is limited along the length direction of the slide groove 14 mainly through the action of the ejector pin 15 and the friction layer 36. The friction layer 36 is made of rubber composite material: rubber filled with carbon black or silica. During friction, the surface peels off to form a new rough layer. Therefore, it is necessary to form a new rough layer between the inner wall of the slide groove 14 and the friction layer 36 through the mutual cooperation between the ejector pin 15 and the friction layer 36, thereby increasing the friction between the ejector pin 15 and the inner wall of the slide groove 14, and achieving the locking effect of the bracket 6 along the length direction of the slide groove 14.

[0025] The driving part includes a gear 16 and two racks 17. The gear 16 is rotatably connected to the inner wall of the sliding cavity. The two racks 17 are respectively arranged on both sides of the gear 16, and the two racks 17 are respectively fixedly connected to the ends of the two ejectors 15. The gear 16 and the rack 17 are arranged in the sliding cavity. Since the bracket 6 is located above the slider 13, the axis of the gear 16 is arranged horizontally, and then a handle 18 can be led out at the end corresponding to the gear 16 and the slider 13. The handle 18 is coaxially arranged with the gear 16. The handle 18 controls the rotation of the gear 16, which is convenient for the staff to operate. When the slider 13 drives the bracket 6 to move to the specified position, the gear 16 is controlled by the control handle 18 to rotate. The two racks 17 start to slide and slide the two ejectors 15 out of the sliding cavity and abut against the corresponding side walls of the slide groove 14, and then start to push the slider 13 to move. At this time, the friction layer 36 produces a rough layer due to friction with the inner wall of the slide groove 14, which further stabilizes the position of the bracket 6.

[0026] The force-bearing component includes a ring 19, a pull rope 20 and a winding part. The ring 19 is sleeved on the outside of the first DC pin 2, the second DC pin 3, the first AC pin 4 or the second AC pin 5. One end of the pull rope 20 is fixedly connected to the outer wall of the ring 19, and the other end is wound by the winding part. The size of the ring 19 is larger than the cross-sectional size of the pin, and the position of the ring 19 sleeved on the pin is located at the position where the support sheet 7 contacts the pin, so the bending work of the pin can be completed by pulling the ring 19; the winding part includes a winding roller 21, a force rope 22 and a force roller 23. The winding roller 21 is rotatably set on the bracket 6, the force roller 23 is coaxially arranged with one end of the winding roller 21, one end of the force rope 22 is wound on the force roller 23, and the other end is provided with a force ring. The function of the force roller 23 and the force rope 22 is mainly to facilitate the staff to apply force. By applying force to the force rope 22, the force roller 23 rotates continuously. At this time, the winding roller 21 starts to continuously wind the pull rope 20 until the pull rope 20 is straightened, and then continues to apply force to the force rope 22. The force roller 23 continues to rotate, and the winding roller 21 applies force to the ring 19 while winding the pull rope 20, thereby achieving the effect of applying force to the ring 19.

[0027] Two gaskets 24, a cooling sheet 25 arranged on the gasket 24 and a power unit for controlling the movement of the gasket 24 are movably arranged in the ring 19. The two gaskets 24 move along the height direction of the ring 19. The two cooling sheets 25 are arranged opposite to each other and face the inside of the ring 19. The cooling sheets 25 are used to cool the bent parts. The cooling sheets 25 are made of polymer gel (such as hydrophilic gel), which contains a large amount of water and volatile components (such as mint and ice). When the applied position generates heat due to bending, of course, the pin will not heat up under normal circumstances. However, after multiple operations and bending, the corresponding bending position starts to heat up and the water evaporates: the water in the gel evaporates after being heated, absorbs the heat from the skin surface, and realizes physical cooling. Since the pin is not bent multiple times infrequently, the cooling sheet 25 will not work most of the time. Since the gasket 24 is elastic and soft, it can protect the bent part.

[0028] The power unit includes a driving ring 26, a driving rod 27 and two driving blocks 28 arranged in the collar 19. The driving block 28 is set in an L shape. The driving block 28 is elastically arranged in the driving ring 26. A driving hole 29 is provided in the middle of the driving ring 26. The driving rod 27 is slidably arranged in the driving hole 29. The cross-sectional radius of the driving rod 27 gradually decreases downward. The peripheral wall of the driving rod 27 abuts against the ends of the two driving blocks 28. The two ends of the driving ring 26 are open and the driving ring 26 is arranged on the inner side of the collar 19 in the height direction. The horizontal section of the driving block 28 is arranged in the driving ring 26, and the vertical section of the driving block 28 is fixedly connected to the gasket 24. The side wall of the driving block 28 is fixedly connected with a moving block The inner wall of the driving ring 26 is provided with a moving groove, and an elastic member is fixedly connected between one end of the moving block and the inner wall of the corresponding end of the moving groove. Therefore, in the initial state, the driving rod 27 is inserted into the driving hole 29. At this time, the elastic member is squeezed and deformed, and the two gaskets 24 are close to the two sides of the ring 19. When the driving rod 27 moves outward from the driving hole 29, under the elastic force of the elastic member, the gasket 24 moves toward the direction of the pin, and the buffering effect of the pin can be achieved. At the same time, under the action of the elastic member, the friction between the cooling plate 25 and the pin is increased, and the friction between the ring 19 and the pin is increased, thereby increasing the probability of the ring 19 slipping out, making it easier to pull the ring 19 to bend the pin.

[0029] The implementation principle of a vertical co-directional rectifier bridge stack in the embodiment of the present application is as follows: in order to prevent the bracket 6 from sliding during the bending process, the cross-section of the slider 13 and the slide groove 14 is set to a T-shape mainly to limit the vertical position of the slider 13, and the bracket 6 is restricted along the length direction of the slide groove 14 mainly through the action of the ejector pin 15 and the friction layer 36. Through the mutual cooperation between the ejector pin 15 and the friction layer 36, a new rough layer is formed between the inner wall of the slide groove 14 and the friction layer 36, thereby increasing the friction between the ejector pin 15 and the inner wall of the slide groove 14, thereby achieving the locking of the bracket 6 along the length direction of the slide groove 14. Effect: In the initial state, the plug-in block 9 is in contact with the bracket 6, the plug-in block 9 is located in the slide groove 14, and the spring 35 is compressed and deformed. When the support piece 7 starts to be rotated, until the plug-in block 9 moves to the position of the plug-in hole 12, the plug-in block 9 is plugged into the plug-in hole 12, and one end of the drive column 10 is slid out of the plug-in hole 12. The length of the drive column 10 is equal to the length of the plug-in hole 12, and the drive column 10 will not slide out of the plug-in hole 12. After the plug-in block 9 is plugged into the plug-in hole 12, the position of the support piece 7 is locked, and at this time, the end of the support piece 7 is better in contact with the position where the pin is to be folded.

[0030] In the initial state, the driving rod 27 is inserted into the driving hole 29. At this time, the elastic member is squeezed and deformed, and the two gaskets 24 are close to the two side positions of the ring 19. When the driving rod 27 moves outward from the driving hole 29, under the elastic force of the elastic member, the gasket 24 moves toward the pin direction. At this time, the buffering effect of the pin can be achieved. At the same time, under the action of the elastic member, the friction between the cooling plate 25 and the pin is increased, thereby increasing the friction between the ring 19 and the pin. By applying force to the force rope 22, the force roller 23 rotates continuously. At this time, the winding roller 21 begins to continuously wind the pull rope 20 until the pull rope 20 is straightened, and continues to apply force to the force rope 22. The force roller 23 continues to rotate. While winding the pull rope 20, the winding roller 21 applies force to the ring 19, and the pin begins to bend at the abutment position of the support piece 7.

[0031] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
