Description

Technical Field

[0001] The present invention relates to the technical field of fixture power supply, and specifically to a large-current fixture for semiconductor laser electrodes. Background Art

[0002] Currently, most semiconductor lasers powered by electrodes use electrode pins or alligator clips for power supply. Since the specifications of the laser electrodes are diverse, with various shapes and sizes, this leads to the need to customize matching electrode pins. There is a crown cage type elastic sheet clamping structure for multiple electrode pins. If the shape of the root of the laser electrode is irregular, it is easy to cause damage to the crown cage and loss of elasticity, resulting in the inability of the electrode pin to make normal contact with the laser electrode and unable to supply power to the laser normally. Moreover, one type of electrode pin can only be applicable to one type of electrode and cannot be used for multiple purposes, which will reduce operation efficiency and increase costs. Some lasers use alligator clips for power supply. Due to the design mechanism of the alligator clip, the alligator clip has a serrated structure, and the laser electrode and the alligator clip have point or line contact, with a small contact area, which leads to the inability to achieve large-current power supply and a significant reduction in the power supply effect. Therefore, a large-current fixture for semiconductor laser electrodes has been developed.

[0003] In the existing large-current fixture for semiconductor laser electrodes, when the fixture drives the electrode connection and the contact part of the fixture drives the electrode to make contact, there will be an inclination angle. The inclination angle causes a small contact area at the contact part of the fixture, thus affecting the power transmission effect of the wiring part in the fixture. At the same time, when installing between the upper and lower fixtures, a positioning roller needs to be installed in the middle of the fixture. When installing the positioning roller, the connecting plate needs to be pushed outward to drive the outer part of the positioning roller to be movably sleeved inside the connecting plate. When the connecting plate is pushed outward, too much pushing force will cause damage and hidden injuries to the connecting plate. Summary of the Invention

[0004] Aiming at the deficiencies of the existing large-current fixture for semiconductor laser electrodes, the present invention provides a large-current fixture for semiconductor laser electrodes, which has the advantages of being independently installed through a power connection board, with a second spring and a third spring installed on the upper part of the power connection board. The second spring and the third spring can push the power connection board to move up and down independently. When the upper and lower power connection boards are squeezed under the action of the elastic force of the support spring, different-level power connection boards can be sequentially contacted and spliced, which can increase the electrode contact surface and thus increase the electrode power-on effect. At the same time, the telescopic jacket and the telescopic rod can be telescopically adjusted under the action of the elastic force of the first spring. After splicing between the first-side connecting plate and the second-side connecting plate, the telescopic jacket and the telescopic rod are driven to contract, that is, it increases the flexibility and stability when installing the position between the upper fixture and the lower fixture, and solves the problems raised in the above background art.

The inside of the outer positioning sleeve is clamped between the limiting sleeve and the inner limiting sleeve. The outside of the outer positioning sleeve is installed outside the first side connecting plate.

[0008] Preferably, spring limiting grooves are fixedly connected inside both the upper clamp and the lower clamp. Both ends of the support spring extend outwards, and at the same time, the baffle installed outside the support spring is clamped inside the spring limiting groove.

[0009] Preferably, motor limiting clamping plates are movably sleeved inside the front ends of both the upper clamp and the lower clamp. The positioning threaded column passes through the motor limiting clamping plate and is fixedly connected to the inside of the outside of the upper clamp or the lower clamp.

[0010] Preferably, the middle part of the connecting rod is conical, and the upper part of the connecting rod is circular. The middle part of the connecting rod is movably sleeved inside the motor limiting clamp plate. A threaded groove is formed inside the lower part of the electrode connector, and the inner part of the lower part of the electrode connector is threadedly connected to the upper part of the connecting rod.

[0011] Preferably, the second spring and the third spring are clamped between the inner limiting baffle and the power connection plate. The connecting plate is clamped outside the lower part of a row of power connection plates. The motor limiting clamp plates installed inside the front ends of the upper clamp and the lower clamp are aligned and installed with each other.

[0012] Preferably, the outer side of the middle part of the connecting rope limiting sleeve is circular. The outer side of the positioning frame outside the sleeve is clamped inside the outside of one side of the upper clamp. The connecting rope passes through the middle of the inside of the connecting rope limiting sleeve, and the inner side of the second fastening bolt can contact the outer side of the connecting rope.

[0013] Compared with the existing large-current fixture for semiconductor laser electrodes, the present invention has the following beneficial effects:

[0014] 1. For this large-current fixture for semiconductor laser electrodes, by loosening the rear end of the upper clamp, the front ends of the upper clamp and the lower clamp can be squeezed and limited inward under the elastic action of the support spring, and the sealing sleeve can be double-squeezed and limited under the elastic action of the second spring and the third spring, which can increase the contact surface of the electrode and enhance the contact effect. At the same time, multiple sealing sleeves are installed on the device, and the sealing sleeves distribute the large current to each electrode connector, extending the service life, eliminating the problem of small contact surface between the alligator clip and the semiconductor laser electrode, and eliminating the problem of short service life of the electrode needle due to the irregular shape of the laser electrode. It can supply power to semiconductor laser electrodes of multiple specifications, greatly increasing the use flexibility, reducing costs, and improving efficiency.

[0015] 2. For this large-current fixture for semiconductor laser electrodes, by passing the connecting rope through the inside of the connecting rope limiting sleeve, adjusting the length of the connecting rope between the connecting rope limiting sleeve and the lower clamp, and simultaneously rotating the second fastening bolt, the second fastening bolt passes through the connecting rope limiting sleeve and squeezes and limits the outer side of the connecting rope, and the second fastening bolt squeezes and limits the position of the connecting rope. That is, during use, the squeezing angle of the rear ends of the upper clamp and the lower clamp can be limited, avoiding the problem of excessive squeezing force. When the connecting rope limiting sleeve of the carbohydrate device is installed, it is convenient for disassembly and limitation.

[0016] 3. When the electrode large-current jig of the semiconductor laser is installed through the position between the upper fixture and the lower fixture, it drives the first side connecting plate and the second side connecting plate to be spliced with each other. At the same time, under the action of elasticity, the telescopic jacket and the telescopic rod can be adjusted by contraction, which is convenient for the limiting sleeve to be clamped inside the connection of the first side connecting plate and the second side connecting plate. An outer positioning sleeve is movably sleeved outside the limiting sleeve. At the same time, when the first fastening bolt is rotated, it can drive the support spring to be limited during installation, and avoid the problem that the telescopic jacket loosens inside the first side connecting plate.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5, A large-current fixture for semiconductor laser electrodes, comprising an upper clamp 1. In the middle of the outside of the upper clamp 1, a first side connecting plate 2 is fixedly connected. A limiting sleeve 3 is movably sleeved in the middle of the first side connecting plate 2. The limiting sleeve 3 drives the positions of the middle parts of the first side connecting plate 2 and the second side connecting plate 4 to be limited. The outside of the limiting sleeve 3 is movably sleeved with a second side connecting plate 4. The limiting sleeve 3 and the second side connecting plate 4 limit the positions of the upper clamp 1 and the lower clamp 27. The lower part of the second side connecting plate 4 is fixedly connected with a lower clamp 27. The inside of the limiting sleeve 3 is fixedly connected with a telescopic clamp sleeve 5. A telescopic rod 6 is movably sleeved inside the telescopic clamp sleeve 5. The telescopic clamp sleeve 5 and the telescopic rod 6 are telescopically adjusted with each other. After the telescopic clamp sleeve 5 and the telescopic rod 6 are telescopically adjusted, the limiting sleeve 3 is driven to be clamped inside the first side connecting plate 2 and the second side connecting plate 4. A first spring 7 is installed at the end of the telescopic rod 6. The first spring 7 provides power to push the telescopic clamp sleeve 5 and the telescopic rod 6 to move outward. In the middle of the outside of the telescopic clamp sleeve 5, an inner limiting sleeve 8 is fixedly connected. The inner limiting sleeve 8 is installed at the position of the outer positioning sleeve 9 to limit the position when the outer positioning sleeve 9 is installed. The outside of the inner limiting sleeve 8 is movably sleeved with the outer positioning sleeve 9. The outside of the outer positioning sleeve 9 is movably sleeved with the outside of the first side connecting plate 2 to prevent the telescopic clamp sleeve 5 from sliding out of the inside of the first side connecting plate 2. A first fastening bolt 10 is threadedly connected inside the inner limiting sleeve 8. By rotating the first fastening bolt 10, the position between the outer positioning sleeve 9 and the limiting sleeve 3 is limited. Inside the upper clamp 1, a spring limiting groove 11 is fixedly connected. The spring limiting groove 11 limits the position of the end of the support spring 12. The outside of the telescopic clamp sleeve 5 is movably sleeved with the support spring 12. The support spring 12 provides power to the other ends inside the upper clamp 1 and the lower clamp 27, and pushes one end of the upper clamp 1 and the lower clamp 27 to be squeezed and limited. Inside the front end of the upper clamp 1, a motor limiting clamping plate 13 is movably sleeved. The motor limiting clamping plate 13 limits the position of each row of connecting rods 14. A connecting rod 14 is movably sleeved inside the motor limiting clamping plate 13. An electrode connector 15 is threadedly connected to the outside of the upper part of the connecting rod 14. The electrode connector 15 connects the current. After the electrode connector 15 and the connecting rod 14 are threadedly spliced, the position of the connecting rod 14 is driven to be installed inside the motor limiting clamping plate 13. A positioning threaded column 16 is installed inside one side of the motor limiting clamping plate 13. The positioning threaded column 16 limits the installation position of the motor limiting clamping plate 13. A lower part of the connecting rod 14 is fixedly connected with an inner limiting baffle 17. The inner limiting baffle 17 is installed inside the third spring 19 to increase the protection when the third spring 19 is installed. A second spring 18 is installed at the lower part of the inner limiting baffle 17. The outside of the lower part of the connecting rod 14 is fixedly connected with a third spring 19. Under the dual elastic clamping action of the second spring 18 and the third spring 19, the problem of deviation when the upper and lower two sealing clamp sleeves 22 are squeezed and limited is reduced. The lower part of the third spring 19 is fixedly connected with a power connection plate 20. The outside of the lower part of the power connection plate 20 is movably sleeved with a connecting plate 21.The connecting plate 21 drives the power connection plates 20 in the same row for connection and limitation. A sealing jacket 22 is installed outside the lower part of the power connection plate 20. The sealing jacket 22 limits the position of the connecting plate 21. At the upper part of the rear end of the lower clamp 27, a connecting rope 23 is fixedly connected. By adjusting the length of the connecting rope 23, the connecting rope 23 can limit the squeezable interval between the upper clamp 1 and the lower clamp 27. Inside the rear end of the upper clamp 1, a connecting rope limiting jacket 24 is movably sleeved. Outside the connecting rope limiting jacket 24, a jacket external positioning frame 25 is movably sleeved. The jacket external positioning frame 25 limits the position of the connecting rope limiting jacket 24. Inside the outside of the connecting rope limiting jacket 24, a second fastening bolt 26 is threadedly connected. By rotating the second fastening bolt 26, the second fastening bolt 26 limits the position of the connecting rope 23 inside the connecting rope limiting jacket 24.,

[0025] Reference Figure 2 and Figure 5 The first spring 7 is installed inside the telescopic jacket 5. The telescopic jacket 5 and the telescopic rod 6 are installed inside the two second side connecting plates 4. By the first spring 7 being movably sleeved inside the telescopic jacket 5, elastic telescoping can be carried out between the telescopic jacket 5 and the telescopic rod 6. That is, when the limiting sleeves 3 installed outside the telescopic jacket 5 and the telescopic rod 6 are movably sleeved inside the first side connecting plate 2 and the second side connecting plate 4, the function of elastic contraction adjustment between the telescopic jacket 5 and the telescopic rod 6 can be increased, and the problem of obstruction when directly installing the telescopic jacket 5 and the support spring 12 can be avoided.

[0026] Reference Figure 5 The first side connecting plate 2 is installed outside the second side connecting plate 4. The inside of the outer positioning sleeve 9 is clamped between the limiting sleeve 3 and the inner limiting sleeve 8. The outside of the outer positioning sleeve 9 is installed outside the first side connecting plate 2. The outside of the first fastening bolt 10 is clamped in the middle of the outside of the outer positioning sleeve 9. After the limiting sleeve 3 is movably sleeved inside the first side connecting plate 2 and the second side connecting plate 4, the rotation direction during the installation of the upper clamp 1 and the lower clamp 27 can be limited. And after the limiting sleeve 3 is movably sleeved inside the first side connecting plate 2 and the second side connecting plate 4, and an outer positioning sleeve 9 is movably sleeved between the inner limiting sleeve 8 and the limiting sleeve 3, and at the same time a first fastening bolt 10 is installed inside the outer positioning sleeve 9, driving the outer positioning sleeve 9 to be clamped outside the first side connecting plate 2, and avoiding the problem that the telescopic jacket 5 slides out between the first side connecting plate 2 and the second side connecting plate 4, increasing the stability and convenience during the installation of the telescopic jacket 5.

[0027] Reference Figure 1 and Figure 2, spring limiting grooves 11 are fixedly connected inside both the upper clamp 1 and the lower clamp 27. Both ends of the support spring 12 extend outward. At the same time, the baffles installed on the outside of the support spring 12 are clamped inside the spring limiting grooves 11. Through the spring limiting grooves 11 fixedly connected inside both the upper clamp 1 and the support spring 12, and the spring limiting grooves 11 can limit the position of the support spring 12. When in use, the support spring 12 is installed in the middle of the upper clamp 1 and the lower clamp 27. Both ends of the support spring 12 are respectively movably sleeved inside the spring limiting grooves 11, and elasticity is generated on the outside of the support spring 12. Under the action of the elasticity, the rear ends of the upper clamp 1 and the lower clamp 27 can be pushed to squeeze forward to the front ends, and the electrodes installed at the front ends of the upper clamp 1 and the lower clamp 27 can maintain a contact state to keep tightness.

[0028] Reference Figure 1 and Figure 3 , motor limiting clamping plates 13 are movably sleeved inside the front ends of both the upper clamp 1 and the lower clamp 27. The positioning threaded post 16 passes through the motor limiting clamping plate 13 and is fixedly connected to the inside of the outside of the upper clamp 1 or the lower clamp 27. By providing grooves inside the upper clamp 1 and the lower clamp 27, and the motor limiting clamping plate 13 is movably sleeved inside the grooves, and the positioning threaded post 16 is installed inside the outside of the motor limiting clamping plate 13, the flexibility and convenience of installing the motor limiting clamping plate 13 can be increased.

[0029] Reference Figure 3 , the middle part of the connecting rod 14 is conical, the upper part of the connecting rod 14 is circular, the middle part of the connecting rod 14 is movably sleeved inside the motor limiting clamping plate 13, and a threaded groove is provided inside the lower part of the electrode connector 15. The inside of the lower part of the electrode connector 15 is threadedly connected to the upper part of the connecting rod 14. By designing the middle part of the connecting rod 14 to be conical, that is, when installing the connecting rod 14, the middle part of the connecting rod 14 is clamped inside the motor limiting clamping plate 13, reducing the problem of the position of the connecting rod 14 shifting. At the same time, the outer thread of the upper part of the connecting rod 14 is sleeved with the electrode connector 15, which can drive the electrode connector 15 to be limited above the motor limiting clamping plate 13, and the lower part of the electrode connector 15 is limited outside the motor limiting clamping plate 13, so as to limit the position of the connecting rod 14 and avoid the problem of the connecting rod 14 shifting.

[0030] Reference Figure 3, the second spring 18 and the third spring 19 are clamped between the inner limiting baffle 17 and the power connection plate 20. The connecting plate 21 is clamped outside the lower part of a row of power connection plates 20. The motors installed inside the front ends of the upper fixture 1 and the lower fixture 27 are aligned and installed with the clamping plates 13. By installing the second spring 18 and the third spring 19 between the connecting rod 14 and the power connection plate 20, under the dual elastic action of the second spring 18 and the third spring 19, the stability can be increased when limiting the power connection plate 20, and while maintaining the downward elasticity of the power connection plate 20, the stability is increased to avoid the problem of the position deviation of the power connection plate 20. At the same time, the connecting plate 21 is movably sleeved on the lower part of a row of power connection plates 20, and a sealing jacket 22 is installed, so that the position of the same row of power connection plates 20 can be squeezed and limited.

[0031] Reference Figure 1 and Figure 4 , the outer side of the middle part of the connecting rope limiting jacket 24 is circular. The outer side of the positioning frame 25 outside the jacket is clamped inside the outside of one side of the upper fixture 1. The connecting rope 23 passes through the middle part inside the connecting rope limiting jacket 24. The inner side of the second fastening bolt 26 can contact the outer side of the connecting rope 23. By designing a circular baffle inside the connecting rope limiting jacket 24, that is, the connecting rope limiting jacket 24 is convenient to be clamped inside the upper fixture 1, and an outer positioning frame 25 of the jacket is movably sleeved outside the connecting rope limiting jacket 24. The outer positioning frame 25 of the jacket can clamp and limit the position of the connecting rope limiting jacket 24. At the same time, the connecting rope 23 passes through the inside of the connecting rope limiting jacket 24 to adjust the length of the connecting rope 23 between the connecting rope limiting jacket 24 and the lower fixture 27. At the same time, the second fastening bolt 26 is rotated. The second fastening bolt 26 passes through the connecting rope limiting jacket 24 and is squeezed and limited on the outer side of the connecting rope 23. The second fastening bolt 26 squeezes and limits the position of the connecting rope 23. That is, during use, the extrusion angle at the rear ends of the upper fixture 1 and the lower fixture 27 can be limited to avoid the problem of excessive extrusion force. When the connecting rope limiting jacket 24 of the carbohydrate device is installed, it is convenient for disassembly and limitation.

[0032] Working principle: When in use, the telescopic jacket 5 and the telescopic rod 6 can be contracted under the elastic action of the first spring 7. That is, after the upper clamp 1 and the lower clamp 27 are sleeved and installed with each other, the telescopic rod 6 and the telescopic jacket 5 are contracted and installed inside the connection of the first side connecting plate 2 and the second side connecting plate 4. At the same time, the limiting sleeve 3 passes through the inside of the first side connecting plate 2 and the second side connecting plate 4. At the same time, the outer side of the limiting sleeve 3 is movably sleeved with an outer positioning sleeve 9, and a first fastening bolt 10 passes through the inside of the outer positioning sleeve 9. By rotating the first fastening bolt 10, a threaded movement is carried out between the first fastening bolt 10 and the inner limiting sleeve 8, so as to clamp and limit the position of the outer positioning sleeve 9, and the outer positioning sleeve 9 limits the connection between the limiting sleeve 3 and the first side connecting plate 2. Moreover, when installing the telescopic rod 6 and the telescopic jacket 5, a support spring 12 is movably sleeved on the outside of the telescopic jacket 5 and the telescopic rod 6. The baffle installed on the outside of the support spring 12 is clamped inside the spring limiting groove 11. The support spring 12 can push the upper clamp 1 and the lower clamp 27 to squeeze inward, so as to mutually squeeze and limit the sealing jacket 22. Moreover, the second spring 18 and the third spring 19 are installed on the outside of the sealing jacket 22. Under the action of the double extrusion forces of the second spring 18 and the third spring 19, the tightness can be increased when the sealing jacket 22 is in contact.
