Description

Technical Field

[0001] The present invention relates to the technical field of diode application, and in particular to a diode packaging structure. Background Art

[0002] One end of the diode has a white ring mark, which is the negative pole, and the other end is the positive pole. In some cases, a homemade rectifier bridge is required in the circuit. The difference between a homemade rectifier bridge and a finished rectifier bridge is that four diodes are selected on site and their negative and positive pins are welded together. This rectifier bridge uses local materials and has a low cost. The disadvantage is that the pins of the four diodes need to be welded together in turn, which requires the assistance of a welding gun. Secondly, each diode is directly exposed to the outside, and the application is not standardized. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a diode packaging structure, including a bottom cabin, a hinged joint is installed at the left end of the bottom cabin, and a hatch cover is connected to the top of the bottom cabin through the hinged joint. The bottom cabin is square, and a packaging assembly is arranged in its square inner cavity. The shape of the hatch cover matches the bottom cabin, and the hatch cover covers the packaging assembly in the bottom cabin when it is rotated downward. The packaging assembly includes four positioning seats fixed in the bottom cabin, and the four positioning seats are distributed in the square cavity of the bottom cabin in a quadrilateral shape, and each positioning seat is parallel to one side of the square cavity, and each positioning seat is provided with a positioning groove, and the four corners of the bottom cabin are provided with a first chamfered surface, and each of the chamfered surfaces is provided with a first pressure hole, and the four corners of the hatch cover are respectively provided with second chamfered surfaces matching the first chamfered surfaces, and the four second chamfered surfaces are provided with second pressure holes that snap-fit ​​and match the first pressure holes, and the second pressure holes are provided on the four second chamfered surfaces. A rubber block is embedded in the hole, and when the second pressure hole is buckled with the first pressure hole, the rubber block is pressed into the first pressure hole. The packaging assembly also includes a first spring connected to the front and rear opposite surfaces of the bottom cabin, and the front and rear positioning seats penetrate and are fixed on the first spring. The packaging assembly also includes a second spring connected to the left and right opposite surfaces, and the positioning seat on the right side penetrates and is fixed on the second spring. A solid rod is connected between the positioning seat on the left side and the left end of the second spring, so that the positioning seat on the left side is suspended in the bottom cabin. The packaging assembly also includes a detection component, which includes a pressure seat fixed on the inner surface of the cabin cover and a locking rod installed in the bottom cabin. There are four locking rods, which are respectively located on the inner sides of four positioning seats. When the cabin cover is rotated onto the bottom cabin, the four locking rods are driven to move by the pressure seat, and the four positioning seats are pushed by the four locking rods to move toward the four inner walls of the bottom cabin respectively.

[0004] As further preferred, the first pressing hole and the second pressing hole are semicircular holes, the rubber block is circular, and the bottom protrudes from the bottom surface of the hatch cover, and the left and right positioning seats are higher than the installation height of the front and rear positioning seats.

[0005] As a further preference, movable grooves are provided at the hinged ends of the hatch cover and the bottom cabin.

[0006] As a further preferred embodiment, the detection component also includes an equalizing seat fixed in the bottom cabin, the equalizing seat is square, and four equalizing grooves are opened inwardly from the four square surfaces of the equalizing seat, and a pressure groove connected to the inner ends of the four equalizing grooves is opened in the middle of the top of the equalizing seat, and each of the equalizing grooves is provided with a locking rod, one end of the locking rod extends from the outer end of the equalizing groove outside the square surface and is connected to the positioning seat on the same side, and the other end of the locking rod extends from the inner end of the equalizing groove into the pressure groove and is installed with an inclined seat. When the cabin cover is rotated onto the bottom cabin, the pressure seat is pressed into the pressure groove and squeezed on the inclined seats of the four locking rods, and the four locking rods push the positioning seat to move linearly outward.

[0007] As a further preferred embodiment, both ends of the positioning groove pass through both ends of the positioning seat, and both ends of the positioning groove face the two first pressure holes on the same side, and when the hatch cover is rotated onto the bottom cabin, both ends of the positioning groove face the two rubber blocks on the same side.

[0008] As a further preferred embodiment, a tilting rod is installed in the middle of the rotating end of the hatch cover, and the tilting rod is located on the bottom side of the left positioning seat. A hinged rod is fixed on the left positioning seat, and the other end of the hinged rod extends to the right and is connected to the solid rod through a hinge shaft. When the hatch cover is rotated upward to open, the tilting rod is driven to rotate upward through the left end, and the end of the tilting rod pushes the left positioning seat to deflect upward, so that the positioning groove on the left positioning seat is deflected upward.

[0009] As a further preferred embodiment, a support rod is fixed in the bottom cabin, and the support rod is located on the bottom side of the left positioning seat and supported on the bottom surface of the left positioning seat to keep the left positioning seat horizontal.

[0010] As a further preferred embodiment, a notch is reserved on the hatch cover, and the notch is close to the hinged end of the hatch cover.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. Four diodes are respectively stuck in the positioning grooves of four positioning seats, so that their positive and negative pins extend from the first pressure holes at both ends of the same side to the outside of the bottom cabin. Since each diode has two pins, four diodes have eight pins. Since the same first pressure hole corresponds to the same side end of the two diodes, the pins of two diodes will extend out of each first pressure hole at the same time, and the two diodes are adjacent, which conforms to the connection sequence of the rectifier bridge. It is equivalent to placing the same-end points of the two diodes in the same first pressure hole. Similarly, the same-end points of the other three diodes are placed in the other three first pressure holes. The cover is rotated onto the bottom cabin. At this time, the four second pressing holes on the hatch cover press the four rubber blocks onto the four first pressing holes respectively. The four rubber blocks are pressed into the four first pressing holes respectively, which is equivalent to squeezing the eight pins of the four diodes together in pairs. The rectifier bridge is quickly overlapped, and the same-pole pins of two adjacent diodes are quickly connected together by this means, replacing the existing welding means. There is no need for a welding gun to assist the operation, and this crimping method is also convenient for the future maintenance of the rectifier bridge. The diodes are covered in the bottom cabin by the hatch cover, so that the rectifier bridge is in a separate space, which is much better than the existing homemade rectifier bridge.

[0013] 2. When the four diodes are pushed in four directions, thrust is provided to the pins at both ends of them respectively. Since the first pressing hole is on the first chamfered surface and the second pressing hole is on the second chamfered surface, as the positioning seat moves toward the cavity wall of the bottom cabin, the thrust of the pins will be converted into pulling force, and the two pins pressed on the same rubber block will be dragged inward by the pulling force. According to the pin distribution positions of the two adjacent diodes, it can be seen that the directions of the two pins when being dragged by the two positioning seats are crossed, thereby ensuring that the two pins are pressed together by the rubber block, and ensuring that the current flows between the pins when the diode is energized.

DETAILED DESCRIPTION

[0021] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0022] In one embodiment, Figure 1-Figure 6 As shown:

[0023] The present embodiment provides a diode packaging structure, including a bottom cabin 1, a hinged joint 2 is installed at the left end of the bottom cabin 1, a hatch cover 3 is connected to the top of the bottom cabin 1 through the hinged joint 2, the bottom cabin 1 is square, and a packaging assembly is arranged in its square inner cavity, the shape of the hatch cover 3 matches the bottom cabin 1, and the hatch cover 3 covers the packaging assembly in the bottom cabin 1 when it rotates downward, and the packaging assembly includes four positioning seats 5 fixed in the bottom cabin 1, the four positioning seats 5 are distributed in the square cavity of the bottom cabin 1 in a quadrilateral shape, and each positioning seat 5 is parallel to one side of the square cavity, and each positioning seat 5 is provided with a positioning groove 23, the four corners of the bottom cabin 1 are provided with first chamfered surfaces 6, and each of the first chamfered surfaces 6 is provided with a first pressing hole 7, the four corners of the hatch cover 3 are respectively provided with second chamfered surfaces 8 matching the first chamfered surfaces 6, and the four second chamfered surfaces 8 are provided with second pressing holes 9 that snap-fit ​​and match the first pressing holes 7, and the second pressing holes 9 are inlaid with rubber blocks 10, when the second pressing hole 9 is buckled with the first pressing hole 7, the rubber block 10 is pressed into the first pressing hole 7, the packaging assembly also includes a first spring 12 connected to the front and rear opposite surfaces of the bottom cabin 1, and the front and rear positioning seats 5 penetrate and are fixed on the first spring 12. The packaging assembly also includes a second spring 13 connected to the left and right opposite surfaces, the positioning seat 5 on the right side penetrates and is fixed on the second spring 13, and a solid rod 14 is connected between the positioning seat 5 on the left side and the left end of the second spring 13, so that the positioning seat 5 on the left side is suspended in the bottom cabin 1. The packaging assembly also includes a detection component, which includes a pressure seat 16 fixed on the inner surface of the hatch cover 3 and a locking rod 17 installed in the bottom cabin 1. There are four locking rods 17, which are respectively located on the inner sides of the four positioning seats 5. When the hatch cover 3 is rotated onto the bottom cabin 1, the four locking rods 17 are driven by the pressure seat 16 to move, and the four locking rods 17 push the four positioning seats 5 to move toward the four inner walls of the bottom cabin 1 respectively.

[0024] The first pressing hole 7 and the second pressing hole 9 are semicircular holes, and the rubber block 10 is circular, with the bottom protruding from the bottom surface of the hatch cover 3 .

[0025] The detection component also includes an equalizing seat 19 fixed in the bottom cabin 1. The equalizing seat 19 is square, and four equalizing grooves 20 are opened inwardly from the four square surfaces of the equalizing seat 19. A pressing groove 21 connected to the inner ends of the four equalizing grooves 20 is opened in the middle of the top of the equalizing seat 19. Each equalizing groove 20 is provided with a locking rod 17. One end of the locking rod 17 extends from the outer end of the equalizing groove 20 outside the square surface and is connected to the positioning seat 5 on the same side. The other end of the locking rod 17 extends from the inner end of the equalizing groove 20 to the pressing groove 21 and is installed with an inclined seat 22. When the hatch cover 3 is rotated onto the bottom cabin 1, the pressing seat 16 is pressed into the pressing groove 21 and squeezed on the inclined seats 22 of the four locking rods 17, and the four locking rods 17 push the positioning seat 5 to move linearly outward.

[0026] When making a rectifier bridge using this packaging structure, select four diodes, then rotate the hatch 3 upward to open it, and respectively clamp the four diodes in the positioning grooves 23 of the four positioning seats 5, so that their positive and negative pins extend from the first pressure holes 7 at both ends of the same side to the outside of the bottom cabin 1. Since each diode has two pins, four diodes have eight pins, and since the same first pressure hole 7 corresponds to the same side ends of the two diodes, the pins of two diodes will extend out of each first pressure hole 7 at the same time, and the two diodes are adjacent, which conforms to the connection sequence of the rectifier bridge, which is equivalent to placing the same-pole ends of the two diodes in the same first pressure hole 7. Similarly, the same-pole ends of the other three diodes The ends are placed in the other three first pressing holes 7, and the hatch cover 3 is rotated to the bottom cabin 1. At this time, the four second pressing holes 9 on the hatch cover 3 press the four rubber blocks 10 on the four first pressing holes 7 respectively. The four rubber blocks 10 are pressed in the four first pressing holes 7 respectively, which is equivalent to squeezing the eight pins of the four diodes together in pairs. The rectifier bridge is quickly overlapped, and the same-pole pins of two adjacent diodes are quickly connected together by this means, replacing the existing welding means, without the need for a welding gun to assist the operation, and this crimping method is also convenient for the future maintenance of the rectifier bridge. These diodes are covered in the bottom cabin 1 by the hatch cover 3, so that the rectifier bridge is in a separate space, which is much better than the existing homemade rectifier bridge.

[0027] Both ends of the positioning groove 23 pass through both ends of the positioning seat 5, and both ends of the positioning groove 23 face the two first pressure holes 7 on the same side. When the hatch cover 3 rotates onto the bottom cabin 1, the two ends of the positioning groove 23 face the two rubber blocks 10 on the same side.

[0028] like Figure 1 , Figure 5 as well as Figure 6As shown, as shown, in addition, when the hatch cover 3 is covered on the bottom cabin 1, the pressing seat 16 will be pressed into the pressing groove 21. Before the pressing seat 16 enters the pressing groove 21, it will first squeeze the four inclined seats 22, and the four inclined seats 22 will push the locking rod 17 outward at the same time, forcing the locking rod 17 to move outward along the equalizing groove 20. When the pressing seat 16 is completely pressed into the pressing groove 21, the outward movement stroke of the locking rod 17 will also be the largest, and their outer ends will push the positioning seat 5 on the same side outward, and the four positioning seats 5 will move in four directions with the four diodes. At the same time, when the hatch cover 3 is covered on the bottom cabin 1, the pins of the four diodes will be pressed on the two first pressing holes 7 and The four diodes are placed between the second pressing holes 9 (that is, between the two rubber blocks 10 on the same side) and pressed tightly. Therefore, when the four diodes are pushed in four directions, thrust is provided to the pins at both ends of them respectively. Since the first pressing hole 7 is on the first chamfered surface 6 and the second pressing hole 9 is on the second chamfered surface 8, as the positioning seat 5 moves toward the cavity wall of the bottom cabin 1, the thrust of the pins will be converted into a pulling force, and the two pins pressed on the same rubber block 10 will be dragged inward by the pulling force. According to the pin distribution positions of the two adjacent diodes, it can be seen that the directions of the two pins when being dragged by the two positioning seats 5 are crossed, thereby ensuring that the two pins are pressed together by the rubber block 10, and ensuring that current flows between the pins when the diode is energized.

[0029] The installation height of the left and right positioning seats 5 is higher than that of the front and rear positioning seats 5. First, it is convenient to cross the first spring 12 and the second spring 13. Second, when the pins of two adjacent diodes are placed in the same first pressure hole 7, the two pins are pressed together up and down. When the two pins are squeezed by the rubber block 10 and dragged inward by the two positioning seats 5, they can be further ensured to be pressed together, and the current is effective when the rectifier bridge is used. When the pressure seat 16 is pressed into the pressure groove 21, it is locked in the pressure groove 21 to prevent the hatch cover 3 from rotating upward, increase the locking force between the hatch cover 3 and the bottom cabin 1, and prevent the locking rod 17 and the positioning seat 5 from automatically retreating.

[0030] like Figure 2 As shown, a notch 27 is reserved on the hatch cover 3, and the notch 27 is close to the hinged end of the hatch cover 3. A tilting rod 24 is installed in the middle of the rotating end of the hatch cover 3, and the tilting rod 24 is located on the bottom side of the left positioning seat 5. A hinged rod 25 is fixed on the left positioning seat 5, and the other end of the hinged rod 25 extends to the right and is connected to the solid rod 14 through a hinge shaft. When the hatch cover 3 is rotated upward to open, the tilting rod 24 is driven to rotate upward through the left end, and the end of the tilting rod 24 pushes the left positioning seat 5 to deflect upward, and the positioning groove 23 on the left positioning seat 5 is deflected upward. At this time, the positioning groove 23 can be seen through the notch 27, which is convenient for placing the diode on the left into the positioning groove 23 of the left positioning seat 5.

[0031] like Figure 2As shown, a support rod 26 is fixed in the bottom cabin 1. The support rod 26 is located at the bottom side of the left positioning seat 5 and supported on the bottom surface of the left positioning seat 5 to keep the left positioning seat 5 horizontal.

This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field. This is hereby explained.
