Description

Technical Field

[0001] This invention belongs to the field of welding fixture structure technology, and specifically relates to a welding fixture for a high-speed connector. Background Technology

[0002] In the wire bonding process of PCB boards for high-speed connectors, there are extremely high requirements for the positioning accuracy and clamping stability of the PCB board. In order to meet the above requirements, in the existing technology, when operators perform the PCB board bonding process of high-speed connectors, they usually use a bonding fixture to position and fix the PCB board, and then use the upper and lower pressing structure of the bonding fixture to press and fix the high-speed line on the PCB board to complete the positioning between the PCB board and the high-speed line. Then, the conductor core of the high-speed line is bonded to the pads on the PCB board.

[0003] However, existing high-speed connector soldering fixtures typically only position the PCB board and high-speed lines on one side of the PCB board. When dealing with high-speed connectors that require soldering high-speed lines on both sides of the PCB board (upper and lower surfaces), the different arrangement of the pads on both sides of the PCB board means that after soldering the high-speed lines on one side, positioning the PCB board to solder the high-speed lines on the other side requires considering factors such as avoiding the high-speed lines already soldered to the PCB. This means that when using existing high-speed connector soldering fixtures to solder high-speed lines on both sides (upper and lower surfaces) of the PCB board, two sets of soldering fixtures are usually required, and the entire soldering process needs to be completed in two stages (after using the first set of soldering fixtures to position and solder the high-speed lines on one side of the PCB board, the PCB board is removed and installed on the second set of soldering fixtures to position and solder the high-speed lines on the other side of the PCB board). This results in low soldering efficiency, high fixture costs, complex operation, low clamping efficiency, and the risk of damaging the high-speed lines soldered in the first stage during the assembly and disassembly process. Summary of the Invention

[0004] To address the shortcomings of the prior art, this invention provides a welding fixture for high-speed connectors. This solves the technical problems of low welding efficiency, high fixture cost, complex operation, low clamping efficiency, and easy damage to the high-speed lines being welded once when welding PCBs that require welding high-speed lines on both sides (upper and lower surfaces) using existing welding fixtures for high-speed connectors.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A welding fixture for a high-speed connector includes: a mounting base plate, a first clamping structure, and a second clamping structure; the mounting base plate is divided into a mounting section and a positioning section arranged sequentially along the X-axis direction; A positioning groove is formed on the upper surface of the positioning section. The positioning groove extends along the X-axis direction. The end of the positioning groove near the mounting section is closed, and the end of the positioning groove away from the mounting section extends to the side of the positioning section away from the mounting section to form a first opening. The positioning groove is used to insert a PCB board, the bottom of the positioning groove is used to support the lower surface of the PCB board, and a positioning clamping mechanism is installed in the positioning groove to clamp and position the PCB board in the positioning groove. The bottom of the positioning groove is provided with a connecting groove, which extends along the X-axis and penetrates to the lower surface of the positioning section. The end of the connecting groove near the mounting section is closed, and the end of the connecting groove away from the mounting section extends to the side of the positioning section away from the mounting section to form a second opening. The first clamping structure includes a first rotating rocker arm and a first pressure plate, and the second clamping structure includes a second rotating rocker arm and a second pressure plate. One end of the first rotating rocker arm is rotatably hinged to the upper surface of the mounting section about the Y-axis, and the first pressure plate is fixedly connected to the other end of the first rotating rocker arm for pressing and fixing the first high-speed wire group that passes through the positioning groove from the first opening to the upper surface of the PCB board. One end of the second rotating rocker arm is rotatably hinged to the lower surface of the mounting section about the Y-axis, and the second pressure plate is fixedly connected to the other end of the second rotating rocker arm for pressing and fixing the second high-speed wire group that passes through the communicating groove from the second opening to the lower surface of the PCB board.

[0006] The high-speed connector welding fixture provided by this invention achieves positioning and fixing of the PCB board installed in the positioning groove by utilizing the positioning clamping mechanism. The first high-speed cable group entering the positioning groove from the first opening is pressed and fixed to the upper surface of the PCB board by the first clamping structure and the second clamping structure, respectively pressing and fixing the second high-speed cable group entering the connecting groove from the second opening to the lower surface of the PCB board. This simultaneously achieves positioning and fixing between the PCB board and the first high-speed cable group to be welded to the upper surface of the PCB board, and between the PCB board and the second high-speed cable group to be welded to the lower surface of the PCB board. The welding device forms a groove on the upper surface of the positioning section using the positioning groove to weld the first high-speed cable group to the positioning groove. The gun inlet channel on the upper surface of the PCB board, through the opening of the connecting groove on the lower surface of the positioning section, forms a welding device to weld the second high-speed line group to the gun inlet channel on the lower surface of the PCB board. This allows the welding fixture of the high-speed connector provided by the present invention to weld PCB boards that need to be welded to both sides (upper and lower surfaces) with high-speed lines, requiring only one fixture and completing the entire welding process in one assembly and disassembly. It has the advantages of high welding efficiency, low fixture cost, simple and quick operation, and high clamping efficiency. It solves the technical problems of low welding efficiency, high fixture cost, complex operation, low clamping efficiency, and easy damage to the high-speed lines being welded once during assembly and disassembly when using existing high-speed connector welding fixtures to weld PCB boards that need to be welded to both sides (upper and lower surfaces) with high-speed lines.

[0007] When using the welding fixture for the high-speed connector provided by this invention to weld the PCB board to the first high-speed line group and the PCB board to the second high-speed line group, the first and second high-speed line groups are respectively pressed and fixed on the upper surface of the PCB board by the first pressure plate and on the lower surface of the PCB board by the second pressure plate. This allows operators (or automated welding equipment) to perform welding quickly and accurately, eliminating the need for repeated adjustments or manual pressing of the high-speed lines during the welding process, directly improving welding efficiency. Simultaneously, the fixed position ensures the consistency of the welding points, reducing defects such as cold solder joints and short circuits, significantly improving welding quality. This is particularly suitable for precision welding scenarios with high signal transmission quality requirements, such as high-speed lines.

[0008] Furthermore, the positioning and clamping mechanism includes a first elastic component, a first positioning block, and a second positioning block; The first elastic component is installed on the first sidewall of the positioning groove in the Y-axis direction. The first elastic component is used to press the first side of the PCB board in the Y-axis direction to press the second side opposite to the first sidewall onto the second sidewall opposite to the first sidewall. The first positioning block is fixedly connected to or integrally formed on the first side wall, and the first positioning block is used to cooperate with the first anti-foolproof positioning groove on the first side; the second positioning block is fixedly connected to or integrally formed on the second side wall; the second positioning block is used to cooperate with the second anti-foolproof positioning groove on the second side.

[0009] By placing the PCB board at the bottom of the positioning groove, the PCB board can be directly positioned in the Z-axis direction. By setting the first positioning block and the second positioning block, the PCB board can be quickly positioned in the X-axis direction by using the first positioning block in cooperation with the first anti-foolproof positioning groove and the second positioning block in cooperation with the second anti-foolproof positioning groove. By pressing the second side of the PCB board in the Y-axis direction against the second sidewall of the positioning groove in the Y-axis direction by the first elastic component, the second sidewall can be used as a positioning surface to quickly position the PCB board in the Y-axis direction. Therefore, the welding fixture for the high-speed connector provided by the present invention has the advantages of simple and quick positioning operation and high positioning accuracy when positioning and fixing the PCB board.

[0010] Furthermore, the positioning and clamping mechanism also includes a second elastic component; The second elastic component is installed on the inner end face of the positioning groove near the mounting section. The second elastic component is used to press the end of the PCB board facing the inner end face to press the first positioning block and the second positioning block onto the inner wall of the first anti-foolproof positioning groove and the inner wall of the second anti-foolproof positioning groove, respectively.

[0011] By setting the second elastic component to press the first positioning block and the second positioning block onto the inner walls of the first and second anti-foolproof positioning grooves respectively, not only can the fitting gap between the first positioning block and the first anti-foolproof positioning groove and the fitting gap between the second positioning block and the second anti-foolproof positioning groove be eliminated, but the positioning error of the PCB board in the X-axis direction caused by these gaps can also be enhanced. This also strengthens the positioning reliability of the PCB board in the positioning groove, ensuring that the PCB board is not easily loosened even with slight vibration or accidental contact during the soldering process.

[0012] Furthermore, a pressure block is fixedly connected to or integrally formed on the first rotating rocker arm; The pressure block is used to press against the upper surface of the PCB board when the first pressure plate presses and fixes the first high-speed wire group on the upper surface of the PCB board.

[0013] By setting the pressure block, it can be ensured that when the first pressure plate presses and fixes the first high-speed line group on the upper surface of the PCB board to complete the positioning between the first high-speed line group and the PCB board, the pressure block can press the upper surface of the PCB board, forcing the lower surface of the PCB board to fit against the bottom of the positioning groove. This not only improves the positioning accuracy of the PCB board in the Z-axis direction, but also prevents the PCB board from warping due to the pressure applied by the first pressure plate and the second pressure plate.

[0014] Furthermore, a first limiting buckle is hinged to the upper surface of the positioning segment, and a second limiting buckle is hinged to the lower surface of the positioning segment. A first tension spring is connected between one end of the first limiting buckle and the upper surface of the positioning segment. The first limiting buckle is used to press and limit the first rotating rocker arm to the upper surface of the positioning segment when the first rotating rocker arm is flipped to fit the upper surface of the positioning segment, so that the first pressure plate presses and fixes the first high-speed line group on the upper surface of the PCB board. A second tension spring is connected between one end of the second limiting buckle and the lower surface of the positioning section. The second limiting buckle is used to press and limit the second rotating rocker arm to the lower surface of the positioning section when the second rotating rocker arm is flipped to fit the lower surface of the positioning section, so that the second pressure plate presses and fixes the second high-speed line group on the lower surface of the PCB board.

[0015] The high-speed connector welding fixture provided by this invention introduces a first locking mechanism consisting of a first limiting buckle and a first tension spring, and a second locking mechanism consisting of a second limiting buckle and a second tension spring. When the first rotating rocker arm flips to fit the upper surface of the positioning section, causing the first wire pressing plate to press and fix the first high-speed wire group on the upper surface of the PCB board, the first limiting buckle can automatically or manually press and limit the first rotating rocker arm on the upper surface of the positioning section under the tension of the first tension spring. When the second rotating rocker arm flips to fit the lower surface of the positioning section, causing the second wire pressing plate to press and fix the second high-speed wire group on the lower surface of the PCB board, the second limiting buckle can automatically or manually press and limit the second rotating rocker arm on the lower surface of the positioning section under the tension of the second tension spring, forming a stable self-locking structure. This ensures that during the welding process, even with slight vibration or accidental contact, the first and second wire pressing plates will not loosen and will always maintain pressure on the first and second high-speed wire groups.

[0016] Furthermore, the first limiting buckle is rotatably hinged to the upper surface of the positioning segment about the X-axis, and the second limiting buckle is rotatably hinged to the lower surface of the positioning segment about the X-axis. The first limiting buckle is provided with a first slot at the end facing the first rotating rocker arm, which corresponds to the first locking platform protruding from the side of the first rotating rocker arm. The end of the second limiting buckle facing the second rotating rocker arm is provided with a second slot corresponding to the second locking platform protruding from the side of the second rotating rocker arm.

[0017] Furthermore, a first torsion spring is provided at the hinge end of the first rotating rocker arm. The first torsion spring is used to drive the first rotating rocker arm to flip away from the positioning section when the first limiting buckle is released from pressing and limiting the first rotating rocker arm. The hinge end of the second rotating rocker arm is provided with a second torsion spring. The second torsion spring is used to drive the second rotating rocker arm to flip away from the positioning section when the second limiting buckle is released from pressing and limiting the second rotating rocker arm.

[0018] Furthermore, the welding fixture for the high-speed connector also includes a third clamping structure and a fourth clamping structure; The third clamping structure includes a third rotating rocker arm and a third pressure plate, and the fourth clamping structure includes a fourth rotating rocker arm and a fourth pressure plate. One end of the third rotating rocker arm is rotatably hinged to the upper surface of the mounting section about the Y-axis, and the third pressure plate is fixedly connected to the other end of the third rotating rocker arm. One end of the fourth rotating rocker arm is rotatably hinged to the lower surface of the mounting section about the Y-axis, and the fourth pressure plate is fixedly connected to the other end of the fourth rotating rocker arm. The first pressure plate is used to press and fix the first high-speed line group that passes through the first opening into the positioning groove onto a first pressure area on the upper surface of the PCB board, so as to fix the welding ends of each high-speed line of the first high-speed line group above a first welding area adjacent to the first pressure area on the upper surface of the PCB board near the mounting section; the third pressure plate is used to press and fix the third high-speed line group that passes through the first opening into the positioning groove onto a second pressure area on the upper surface of the PCB board at intervals on the side of the first pressure area away from the mounting section, so as to fix the welding ends of each high-speed line of the third high-speed line group above a second welding area on the upper surface of the PCB board between the first pressure area and the second pressure area; The second pressure plate is used to press and fix the second high-speed line group that passes through the second opening into the connecting groove onto the third pressure area in the lower surface of the PCB board, so as to fix the solder ends of each high-speed line of the second high-speed line group below the third solder area adjacent to the third pressure area on the lower surface of the PCB board, near the mounting section; the fourth pressure plate is used to press and fix the fourth high-speed line group that passes through the second opening into the connecting groove onto the fourth pressure area in the lower surface of the PCB board, spaced apart from the third pressure area on the side away from the mounting section, so as to fix the solder ends of each high-speed line of the fourth high-speed line group below the fourth solder area in the lower surface of the PCB board, located between the third pressure area and the fourth pressure area.

[0019] By setting the third and fourth clamping structures, the third high-speed line group is first pressed and fixed onto the second clamping area on the upper surface of the PCB board using the third pressure plate, so that the soldering ends of each high-speed line of the third high-speed line group are fixed above the second soldering area on the upper surface of the PCB board. Then, the soldering of each high-speed line of the third high-speed line group on the second soldering area is completed, thus completing the soldering of a layer of high-speed lines (i.e., the third high-speed line group) on the upper surface of the PCB board close to the PCB board. Then, the first pressure plate is used to press and fix the first high-speed line group onto the first clamping area on the upper surface of the PCB board, so that the soldering ends of each high-speed line of the first high-speed line group are fixed above the first soldering area on the upper surface of the PCB board. Then, the soldering of each high-speed line of the first high-speed line group on the second soldering area is completed. The welding on the first welding area completes the welding of one layer of high-speed lines (i.e., the first high-speed line group) on the upper surface of the PCB board away from the PCB board, and then completes the welding of two layers of high-speed lines (i.e., the third high-speed line group close to the PCB board and the first high-speed line group away from the PCB board) on the upper surface of the PCB board. The welding of two layers of high-speed lines (i.e., the fourth high-speed line group close to the PCB board and the second high-speed line group away from the PCB board) on the lower surface of the PCB board is done in the same way. In the whole welding process, the two pressing and welding do not interfere with each other, and the operation is simple. This allows the welding fixture of the high-speed connector provided by the present invention to adapt well to and simplify the welding process of PCB boards that need to be welded with two layers of high-speed lines on both sides (upper surface and lower surface) (the welding areas corresponding to each layer of high-speed lines are arranged at intervals along the X-axis direction).

[0020] Furthermore, a third limiting buckle is hinged to the upper surface of the positioning segment, and a fourth limiting buckle is hinged to the lower surface of the positioning segment. A third tension spring is connected between one end of the third limiting buckle and the upper surface of the positioning section. The third limiting buckle is used to press and limit the third rotating rocker arm to the upper surface of the positioning section when the third rotating rocker arm is flipped to fit the upper surface of the positioning section, so that the third pressure plate presses and fixes the third high-speed wire group on the second pressure area. A fourth tension spring is connected between one end of the fourth limiting buckle and the lower surface of the positioning section. The fourth limiting buckle is used to press and limit the fourth rotating rocker arm to the lower surface of the positioning section when the fourth rotating rocker arm flips to fit the lower surface of the positioning section, so that the fourth pressure plate presses and fixes the fourth high-speed wire group on the fourth pressure area.

[0021] The high-speed connector welding fixture provided by this invention introduces a third locking mechanism consisting of a third limiting buckle and a third tension spring, and a fourth locking mechanism consisting of a fourth limiting buckle and a fourth tension spring. When the third rotating rocker arm flips to fit the upper surface of the positioning section, causing the third wire pressing plate to press and fix the third high-speed wire group on the second pressing area in the upper surface of the PCB board, the third limiting buckle can automatically or manually press and limit the third rotating rocker arm on the upper surface of the positioning section under the tension of the third tension spring. When the fourth rotating rocker arm flips to fit the lower surface of the positioning section, causing the fourth wire pressing plate to press and fix the fourth high-speed wire group on the fourth pressing area in the lower surface of the PCB board, the fourth limiting buckle can automatically or manually press and limit the fourth rotating rocker arm on the lower surface of the positioning section under the tension of the fourth tension spring, forming a stable self-locking structure. This ensures that during the welding process, even with slight vibration or accidental contact, the third and fourth pressure plates will not loosen and will always maintain pressure on the third and fourth high-speed wire groups.

[0022] The first, second, third, and fourth locking mechanisms all utilize the elasticity of springs for locking and unlocking, making operation extremely simple. Operators only need to overcome the spring force to pry open the corresponding latch to release the rotating rocker arm, or press the rotating rocker arm under the corresponding latch to complete the locking process. This design eliminates the need for complex locking components (such as screws or latches), simplifying operation and improving production efficiency.

[0023] Furthermore, the third limiting buckle is rotatably hinged to the upper surface of the positioning segment about the X-axis, and the fourth limiting buckle is rotatably hinged to the lower surface of the positioning segment about the X-axis. The third limiting buckle is provided with a third slot at one end facing the third rotating rocker arm, which corresponds to the third locking platform protruding from the side of the third rotating rocker arm. The fourth limiting buckle is provided with a fourth slot at one end facing the fourth rotating rocker arm, which corresponds to the fourth locking platform protruding from the side of the fourth rotating rocker arm.

[0024] Furthermore, a third torsion spring is provided at the hinge end of the third rotating rocker arm. The third torsion spring is used to drive the third rotating rocker arm to flip away from the positioning section when the third limiting buckle is released from pressing and limiting the third rotating rocker arm. The hinge end of the fourth rotating rocker arm is provided with a fourth torsion spring, which is used to drive the fourth rotating rocker arm to flip away from the positioning section when the fourth limiting buckle is released from pressing and limiting the fourth rotating rocker arm.

[0025] By configuring the first, second, third, and fourth torsion springs, the welding fixture for the high-speed connector provided by this invention allows the torsion springs to automatically spring open the rotating rocker arms after the locking of the first, second, third, and fourth rotating rocker arms is released, causing them to flip to the side away from the positioning section. This design eliminates the need for operators to manually lift the rotating rocker arms, significantly improving efficiency, especially when dealing with multiple rotating rocker arms. The operation process is simplified to simply releasing the latch, and the corresponding rotating rocker arm automatically springs open, achieving semi-automatic operation.

[0026] Furthermore, the side of the positioning section away from the mounting section is provided with a magnetic attraction structure for attracting the mounting base plate together with the clamping fixture that holds the first high-speed line group, the second high-speed line group, the third high-speed line group and the fourth high-speed line group.

[0027] The welding fixture for the high-speed connector provided by this invention has at least the following technical effects or advantages: 1. The welding fixture for the high-speed connector provided by the present invention achieves positioning and fixing of the PCB board installed in the positioning groove by utilizing the positioning clamping mechanism. The first high-speed cable group entering the positioning groove from the first opening is pressed and fixed to the upper surface of the PCB board by utilizing the first clamping structure and the second clamping structure, respectively, and the second high-speed cable group entering the connecting groove from the second opening is pressed and fixed to the lower surface of the PCB board. This simultaneously achieves positioning and fixing between the PCB board and the first high-speed cable group to be welded to the upper surface of the PCB board, and between the PCB board and the second high-speed cable group to be welded to the lower surface of the PCB board. The first high-speed cable group is welded using a welding device formed by the slot on the upper surface of the positioning section of the positioning groove. The welding device forms an opening on the lower surface of the positioning section through the opening of the welding gun channel on the upper surface of the PCB board, and welds the second high-speed line group to the welding gun channel on the lower surface of the PCB board. This allows the welding fixture of the high-speed connector provided by the present invention to weld PCB boards that need to be welded to both sides (upper and lower surfaces) with high-speed lines. Only one fixture is needed, and the entire welding process can be completed in one assembly and disassembly. It has the advantages of high welding efficiency, low fixture cost, simple and quick operation, and high clamping efficiency. It solves the technical problems of low welding efficiency, high fixture cost, complicated operation, low clamping efficiency, and easy damage to the high-speed lines welded at one time when using the existing high-speed connector welding fixture to weld PCB boards that need to be welded to both sides (upper and lower surfaces) with high-speed lines.

[0028] 2. When using the welding fixture for the high-speed connector provided by this invention to weld the PCB board to the first high-speed line group and the PCB board to the second high-speed line group, since the first high-speed line group and the second high-speed line group are respectively pressed and fixed on the upper surface of the PCB board by the first pressure plate and on the lower surface of the PCB board by the second pressure plate, operators (or automated welding equipment) can quickly and accurately perform welding without repeatedly adjusting or manually holding the high-speed lines during the welding process, directly improving welding efficiency. At the same time, the fixed position ensures the consistency of the welding points, reduces defects such as cold solder joints and short circuits, and significantly improves welding quality, making it particularly suitable for precision welding scenarios with high signal transmission quality requirements, such as high-speed lines.

[0029] 3. By placing the PCB board at the bottom of the positioning groove, the PCB board can be directly positioned in the Z-axis direction. By setting the first positioning block and the second positioning block, the first positioning block cooperates with the first anti-foolproof positioning groove, and the second positioning block cooperates with the second anti-foolproof positioning groove, the PCB board can be quickly positioned in the X-axis direction. By pressing the second side of the PCB board in the Y-axis direction against the second sidewall of the positioning groove in the Y-axis direction using the first elastic component, the second sidewall can be used as a positioning surface to quickly position the PCB board in the Y-axis direction. This makes the welding fixture for the high-speed connector provided by the present invention simple and quick in positioning and fixing the PCB board, with high clamping efficiency and high positioning accuracy. At the same time, since the clamping force provided by the first elastic component is flexible, it can adapt to the slight difference in the size of the PCB board in the Y-axis direction, ensuring stable clamping while avoiding damage to the corners or stress concentration of the PCB board that may be caused by using rigid clips.

[0030] 4. By setting the second elastic component to press the first positioning block and the second positioning block onto the inner walls of the first and second anti-foolproof positioning grooves respectively, not only can the fitting gap between the first positioning block and the first anti-foolproof positioning groove and the fitting gap between the second positioning block and the second anti-foolproof positioning groove be eliminated, thus eliminating the positioning error of the PCB board in the X-axis direction caused by these gaps, but also the positioning reliability of the PCB board in the positioning groove can be enhanced, ensuring that the PCB board is not easily loosened even with slight vibration or accidental contact during the soldering process. At the same time, since the clamping force provided by the second elastic component is flexible, it can adapt to the slight differences in the dimensions of the PCB board in the X-axis direction, ensuring stable clamping while avoiding damage to the corners or stress concentration of the PCB board that may be caused by using rigid clips.

[0031] 5. By setting the pressure block, it can be ensured that when the first pressure plate presses and fixes the first high-speed line group on the upper surface of the PCB board to complete the positioning between the first high-speed line group and the PCB board, the pressure block can press the upper surface of the PCB board, forcing the lower surface of the PCB board to fit against the bottom of the positioning groove. This not only improves the positioning accuracy of the PCB board in the Z-axis direction, but also prevents the PCB board from warping due to the pressure applied by the first pressure plate and the second pressure plate.

[0032] 6. The high-speed connector welding fixture provided by this invention introduces a first locking mechanism consisting of a first limiting buckle and a first tension spring, and a second locking mechanism consisting of a second limiting buckle and a second tension spring. When the first rotating rocker arm flips to fit the upper surface of the positioning section, causing the first wire pressing plate to press and fix the first high-speed wire group on the upper surface of the PCB board, the first limiting buckle can automatically or manually press and limit the first rotating rocker arm on the upper surface of the positioning section under the tension of the first tension spring. When the second rotating rocker arm flips to fit the lower surface of the positioning section, causing the second wire pressing plate to press and fix the second high-speed wire group on the lower surface of the PCB board, the second limiting buckle can automatically or manually press and limit the second rotating rocker arm on the lower surface of the positioning section under the tension of the second tension spring, forming a stable self-locking structure. This ensures that during the welding process, even with slight vibration or accidental contact, the first and second wire pressing plates will not loosen and will always maintain pressure on the first and second high-speed wire groups.

[0033] 7. By setting the third clamping structure and the fourth clamping structure, firstly, the third high-speed line group is pressed and fixed on the second clamping area on the upper surface of the PCB board using the third pressure plate, so that the soldering ends of each high-speed line of the third high-speed line group are fixed above the second soldering area on the upper surface of the PCB board. Then, the soldering of each high-speed line of the third high-speed line group on the second soldering area is completed, thereby completing the soldering of a layer of high-speed lines (i.e., the third high-speed line group) on the upper surface of the PCB board close to the PCB board. Then, the first pressure plate is used to press and fix the first high-speed line group on the first clamping area on the upper surface of the PCB board, so that the soldering ends of each high-speed line of the first high-speed line group are fixed above the first soldering area on the upper surface of the PCB board. Then, the soldering of each high-speed line of the first high-speed line group on the second soldering area is completed. The welding on the first welding area completes the welding of one layer of high-speed lines (i.e., the first high-speed line group) on the upper surface of the PCB board away from the PCB board, and then completes the welding of two layers of high-speed lines (i.e., the third high-speed line group close to the PCB board and the first high-speed line group away from the PCB board) on the upper surface of the PCB board. The welding of two layers of high-speed lines (i.e., the fourth high-speed line group close to the PCB board and the second high-speed line group away from the PCB board) on the lower surface of the PCB board is done in the same way. In the whole welding process, the two pressing and welding do not interfere with each other, and the operation is simple. This allows the welding fixture of the high-speed connector provided by the present invention to adapt well to and simplify the welding process of PCB boards that need to be welded with two layers of high-speed lines on both sides (upper surface and lower surface) (the welding areas corresponding to each layer of high-speed lines are arranged at intervals along the X-axis direction).

[0034] 8. The welding fixture for the high-speed connector provided by the present invention introduces a third locking mechanism composed of the third limiting buckle and the third tension spring, and a fourth locking mechanism composed of the fourth limiting buckle and the fourth tension spring; when the third rotating rocker arm flips to fit the upper surface of the positioning section, so that the third wire pressing plate presses and fixes the third high-speed wire group on the second pressing area in the upper surface of the PCB board, the third limiting buckle can automatically or manually press and limit the third rotating rocker arm on the upper surface of the positioning section under the tension of the third tension spring; when the fourth rotating rocker arm flips to fit the lower surface of the positioning section, so that the fourth wire pressing plate presses and fixes the fourth high-speed wire group on the fourth pressing area in the lower surface of the PCB board, the fourth limiting buckle can automatically or manually press and limit the fourth rotating rocker arm on the lower surface of the positioning section under the tension of the fourth tension spring, forming a stable self-locking structure. This ensures that during the welding process, even with slight vibration or accidental contact, the third and fourth pressure plates will not loosen and will always maintain pressure on the third and fourth high-speed wire groups.

[0035] 9. The first, second, third, and fourth locking mechanisms all utilize the elastic force of springs for locking and unlocking, making operation very simple. The operator only needs to overcome the spring force to pry open the corresponding latch to release the corresponding rotating rocker arm, or press the rotating rocker arm under the corresponding latch to complete the locking. This design eliminates the need for complex locking components (such as screws or latches), simplifying the operation and improving production efficiency.

[0036] 10. By setting the first torsion spring, the second torsion spring, the third torsion spring, and the fourth torsion spring, the welding fixture of the high-speed connector provided by the present invention, after releasing the lock on the first, second, third, and fourth rotating rocker arms, will have the spring force of the torsion springs automatically spring open the rotating rocker arms, causing them to flip to the side away from the positioning section. This design eliminates the need for operators to manually lift the rotating rocker arms, especially when dealing with multiple rotating rocker arms, resulting in a more significant improvement in efficiency. The operation process is simplified to releasing the latch, and the corresponding rotating rocker arm automatically springs open, achieving semi-automatic operation. The automatically spring-opening rotating rocker arm will remain in a position away from the working area, providing unobstructed space for removing the soldered PCB board and placing new PCB boards and wires, avoiding damage to the soldered wires or PCB boards due to forgetting to lift the rocker arm or improper operation.

[0037] 11. The engagement of the card slot and the card platform (i.e., the engagement of the first card slot with the corresponding first card platform, the engagement of the second card slot with the corresponding second card platform, the engagement of the third card slot with the corresponding third card platform, and the engagement of the fourth card slot with the corresponding fourth card platform) can provide clear mechanical feedback (such as a slight clicking sound or feel) when locked, so that the operator can intuitively judge whether the rocker arm has been locked in place, avoiding clamping failure caused by incomplete locking.

[0038] 12. When the welding fixture and the wire clamping fixture are connected via a connecting key, the magnetic attraction structure (such as a magnet) generates an attractive force, guiding the two fixtures to fit together quickly and accurately. This reduces the difficulty of alignment for the operator and improves the efficiency of fixture assembly. The magnetic attraction provides a continuous and flexible holding force for the connection between the two fixtures. It ensures that the two fixtures remain tightly fitted during the welding operation and will not accidentally detach due to vibration or wire tension, thus enhancing the stability of the entire fixture system.

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] like Figures 1 to 5 As shown, this embodiment provides a welding fixture for a high-speed connector, including: a mounting base plate 1, a first clamping structure 2, and a second clamping structure 3; the mounting base plate 1 is divided into a mounting section and a positioning section arranged sequentially along the X-axis direction; A positioning groove 1.1 is provided on the upper surface of the positioning section. The positioning groove 1.1 extends along the X-axis direction. The end of the positioning groove 1.1 near the installation section is closed, and the end of the positioning groove 1.1 away from the installation section extends to the side of the positioning section away from the installation section to form a first opening. The positioning groove 1.1 is used to insert the PCB board 4. The bottom of the positioning groove 1.1 is used to support the lower surface of the PCB board 4. A positioning clamping mechanism is installed in the positioning groove 1.1. The positioning clamping mechanism is used to clamp and position the PCB board 4 in the positioning groove 1.1. The bottom of the positioning groove 1.1 is provided with a connecting groove 1.2. The connecting groove 1.2 extends along the X-axis and penetrates to the lower surface of the positioning section. The end of the connecting groove 1.2 near the installation section is closed, and the end of the connecting groove 1.2 away from the installation section extends to the side of the positioning section away from the installation section to form a second opening. The first clamping structure 2 includes a first rotating rocker arm 2.1 and a first wire pressing plate 2.2. The second clamping structure 3 includes a second rotating rocker arm 3.1 and a second wire pressing plate 3.2. One end of the first rotating rocker arm 2.1 is rotatably hinged to the upper surface of the mounting section. The first wire pressing plate 2.2 is fixedly connected to the other end of the first rotating rocker arm 2.1 and is used to press and fix the first high-speed wire group that passes through the first opening into the positioning groove 1.1 onto the upper surface of the PCB board 4. One end of the second rotating rocker arm 3.1 is rotatably hinged to the lower surface of the mounting section. The second wire pressing plate 3.2 is fixedly connected to the other end of the second rotating rocker arm 3.1 and is used to press and fix the second high-speed wire group that passes through the second opening into the connecting groove 1.2 onto the lower surface of the PCB board 4.

[0043] The high-speed connector welding fixture provided by this invention achieves positioning and fixing of the PCB board 4 installed in the positioning groove 1.1 by utilizing a positioning clamping mechanism. The first high-speed cable group, which enters the positioning groove 1.1 from the first opening, is pressed and fixed to the upper surface of the PCB board 4 by the first clamping structure 2 and the second clamping structure 3, respectively, and the second high-speed cable group, which enters the connecting groove 1.2 from the second opening, is pressed and fixed to the lower surface of the PCB board 4. This simultaneously achieves positioning and fixing between the PCB board 4 and the first high-speed cable group to be welded to the upper surface of the PCB board 4, and between the PCB board 4 and the second high-speed cable group to be welded to the lower surface of the PCB board 4. A welding device is formed by the slot on the upper surface of the positioning section of the positioning groove 1.1 to weld the first high-speed cable group to the PCB board 4. The gun inlet channel on the upper surface of the PCB board 4 is formed by the opening of the connecting groove 1.2 on the lower surface of the positioning section to form a welding device to weld the second high-speed line group to the gun inlet channel on the lower surface of the PCB board 4. This means that when the welding fixture of the high-speed connector provided by the present invention is used to weld the PCB board 4 which needs to be welded to both sides (upper and lower surfaces), only one fixture is needed, and the entire welding process can be completed in one assembly and disassembly. It has the advantages of high welding efficiency, low fixture cost, simple and quick operation, and high clamping efficiency. It solves the technical problems of low welding efficiency, high fixture cost, complicated operation, low clamping efficiency, and easy damage to the high-speed lines welded at one time when using the existing high-speed connector welding fixture to weld the PCB board 4 which needs to be welded to both sides (upper and lower surfaces).

[0044] When using the welding fixture for the high-speed connector provided by this invention to weld the PCB board 4 to the first high-speed line group and to the second high-speed line group, the first and second high-speed line groups are respectively pressed and fixed on the upper surface of the PCB board 4 by the first pressure plate 2.2 and on the lower surface of the PCB board 4 by the second pressure plate 3.2. This allows operators (or automated welding equipment) to perform welding quickly and accurately, eliminating the need for repeated adjustments or manual pressing of the high-speed lines during the welding process, thus directly improving welding efficiency. Simultaneously, the fixed position ensures the consistency of the welding points, reducing defects such as cold solder joints and short circuits, significantly improving welding quality. This is particularly suitable for precision welding scenarios with high signal transmission quality requirements, such as high-speed lines.

[0045] Preferably, in this embodiment, such as Figure 2 and Figure 3 As shown, the positioning and clamping mechanism includes a first elastic component 5, a first positioning block 6, and a second positioning block 7; The first elastic component 5 is installed on the first sidewall 1.1.1 of the positioning groove 1.1 in the Y-axis direction. The first elastic component 5 is used to press the first side of the PCB board 4 in the Y-axis direction so as to press the second side opposite to the first sidewall 1.1.1 onto the second sidewall opposite to the first sidewall. The first positioning block 6 is fixedly connected or integrally formed on the first side wall 1.1.1, and the first positioning block 6 is used to cooperate with the first anti-foolproof positioning groove 1.1 on the first side wall; the second positioning block 7 is fixedly connected or integrally formed on the second side wall; the second positioning block 7 is used to cooperate with the second anti-foolproof positioning groove 1.1 on the second side wall.

[0046] By placing the PCB board 4 at the bottom of the positioning groove 1.1, the PCB board 4 can be directly positioned in the Z-axis direction. By setting the first positioning block 6 and the second positioning block 7, the PCB board 4 can be quickly positioned in the X-axis direction by using the first positioning block 6 in cooperation with the first anti-foolproof positioning groove 1.1 and the second positioning block 7 in cooperation with the second anti-foolproof positioning groove 1.1. The second side of the PCB board 4 in the Y-axis direction is pressed against the second side wall of the positioning groove 1.1 in the Y-axis direction by the first elastic component 5, so that the second side wall can be used as the positioning surface to complete the rapid positioning of the PCB board 4 in the Y-axis direction. Therefore, the welding fixture of the high-speed connector provided by the present invention has the advantages of simple and quick positioning operation and high positioning accuracy when positioning and fixing the PCB board 4.

[0047] Preferably, in this embodiment, such as Figure 2 and Figure 3 As shown, the positioning and clamping mechanism also includes a second elastic component 8; The second elastic component 8 is installed on the inner end face of the positioning groove 1.1 near the mounting section. The second elastic component 8 is used to press the end of the PCB board 4 facing the inner end face, so as to press the first positioning block 6 and the second positioning block 7 onto the inner wall of the first anti-foolproof positioning groove 1.1 and the inner wall of the second anti-foolproof positioning groove 1.1, respectively.

[0048] By setting the second elastic component 8 to press the first positioning block 6 and the second positioning block 7 onto the inner wall of the first anti-foolproof positioning groove 1.1 and the inner wall of the second anti-foolproof positioning groove 1.1 respectively, it can not only eliminate the positioning error of the PCB board 4 in the X-axis direction caused by the fit gap between the first positioning block 6 and the first anti-foolproof positioning groove 1.1 and the fit gap between the second positioning block 7 and the second anti-foolproof positioning groove 1.1, but also enhance the positioning reliability of the PCB board 4 in the positioning groove 1.1, ensuring that the PCB board 4 will not easily loosen even if there is slight vibration or accidental contact during the soldering process.

[0049] Specifically, in this embodiment, such as Figure 2 and Figure 3As shown, a pressure block 9 is fixedly connected or integrally formed on the first rotating rocker arm 2.1; The pressure block 9 is used to press the first high-speed line group onto the upper surface of the PCB board 4 when the first pressure plate 2.2 presses and fixes it onto the upper surface of the PCB board 4.

[0050] By setting the pressure block 9, it can be ensured that when the first high-speed line group is pressed and fixed on the upper surface of the PCB board 4 by the first pressure plate 2.2 to complete the positioning between the first high-speed line group and the PCB board 4, the pressure block 9 can press the upper surface of the PCB board 4, forcing the lower surface of the PCB board 4 to fit with the bottom of the positioning groove 1.1. This not only improves the positioning accuracy of the PCB board 4 in the Z-axis direction, but also prevents the PCB board 4 from warping due to the pressure applied by the first pressure plate 2.2 and the second pressure plate 3.2.

[0051] Preferably, in this embodiment, such as Figures 1 to 5 As shown, a first limiting buckle 10 is hinged to the upper surface of the positioning section, and a second limiting buckle 11 is hinged to the lower surface of the positioning section. A first tension spring 12 is connected between one end of the first limiting buckle 10 and the upper surface of the positioning section. The first limiting buckle 10 is used to press and limit the first rotating rocker arm 2.1 on the upper surface of the positioning section when the first rotating rocker arm 2.1 flips to fit the upper surface of the positioning section, so that the first pressure plate 2.2 presses and fixes the first high-speed line group on the upper surface of the PCB board 4. A second tension spring 13 is connected between one end of the second limiting buckle 11 and the lower surface of the positioning section. The second limiting buckle 11 is used to press and limit the second rotating rocker arm 3.1 on the lower surface of the positioning section when the second pressure plate 3.2 presses and fixes the second high-speed line group on the lower surface of the PCB board 4.

[0052] The high-speed connector welding fixture provided by this invention introduces a first locking mechanism consisting of a first limiting buckle 10 and a first tension spring 12, and a second locking mechanism consisting of a second limiting buckle 11 and a second tension spring 13. When the first rotating rocker arm 2.1 is flipped to fit the upper surface of the positioning section, so that the first wire pressing plate 2.2 presses and fixes the first high-speed wire group on the upper surface of the PCB board 4, the first limiting buckle 10 can automatically or manually press and limit the first rotating rocker arm 2.1 on the upper surface of the positioning section under the tension of the first tension spring 12. When the second rotating rocker arm 3.1 is flipped to fit the lower surface of the positioning section, so that the second wire pressing plate 3.2 presses and fixes the second high-speed wire group on the lower surface of the PCB board 4, the second limiting buckle 11 can automatically or manually press and limit the second rotating rocker arm 3.1 on the lower surface of the positioning section under the tension of the second tension spring 13, forming a stable self-locking structure. This ensures that during the welding process, even with slight vibration or accidental contact, the first pressure plate 2.2 and the second pressure plate 3.2 will not loosen and will always maintain tight pressure on the first and second high-speed wire groups.

[0053] Specifically, in this embodiment, such as Figures 1 to 6 As shown, the first limiting buckle 10 is hinged to the upper surface of the positioning section in a rotatable manner around the X-axis, and the second limiting buckle 11 is hinged to the lower surface of the positioning section in a rotatable manner around the X-axis. The first limiting buckle 10 has a first slot at one end facing the first rotating rocker arm 2.1, which corresponds to the first locking platform 2.1.1 protruding from the side of the first rotating rocker arm 2.1; The second limiting buckle 11 has a second slot at one end facing the second rotating rocker arm 3.1, which corresponds to the second locking platform 3.1.1 protruding from the side of the second rotating rocker arm 3.1.

[0054] Preferably, in this embodiment, such as Figure 2 and Figure 4 As shown, a first torsion spring 2.3 is provided at the hinge end of the first rotating rocker arm 2.1. The first torsion spring 2.3 is used to drive the first rotating rocker arm 2.1 to flip away from the positioning section when the first limiting buckle 10 releases the pressing limit on the first rotating rocker arm 2.1. The hinge end of the second rotating rocker arm 3.1 is provided with a second torsion spring 3.3. The second torsion spring 3.3 is used to drive the second rotating rocker arm 3.1 to flip away from the positioning section when the second limiting buckle 11 releases the pressing limit on the second rotating rocker arm 3.1.

[0055] Preferably, in this embodiment, such as Figures 1 to 5 As shown, the welding fixture for the high-speed connector also includes a third clamping structure 14 and a fourth clamping structure 15. The third clamping structure 14 includes a third rotating rocker arm 14.1 and a third pressure plate 14.2. The fourth clamping structure 15 includes a fourth rotating rocker arm 15.1 and a fourth pressure plate 15.2. One end of the third rotating rocker arm 14.1 is rotatably hinged to the upper surface of the mounting section, and the third pressure plate 14.2 is fixedly connected to the other end of the third rotating rocker arm 14.1. One end of the fourth rotating rocker arm 15.1 is rotatably hinged to the lower surface of the mounting section, and the fourth pressure plate 15.2 is fixedly connected to the other end of the fourth rotating rocker arm 15.1. The first pressure plate 2.2 is used to press and fix the first high-speed line group that passes through the first opening into the positioning groove 1.1 onto the first pressure area 4.1 on the upper surface of the PCB board 4, so as to fix the welding ends of each high-speed line of the first high-speed line group above the first welding area 4.2 adjacent to the first pressure area 4.1 near the mounting section on the upper surface of the PCB board 4; the third pressure plate 14.2 is used to press and fix the third high-speed line group that passes through the first opening into the positioning groove 1.1 onto the second pressure area 4.3 on the upper surface of the PCB board 4 at intervals on the side of the first pressure area 4.1 away from the mounting section, so as to fix the welding ends of each high-speed line of the third high-speed line group above the second welding area 4.4 between the first pressure area 4.1 and the second pressure area 4.3 on the upper surface of the PCB board 4; The second pressure plate 3.2 is used to press and fix the second high-speed line group that passes through the second opening into the connecting groove 1.2 onto the third pressure area 4.5 on the lower surface of the PCB board 4, so as to fix the solder ends of each high-speed line of the second high-speed line group below the third soldering area 4.6 adjacent to the third pressure area 4.5 near the mounting section on the lower surface of the PCB board 4; the fourth pressure plate 15.2 is used to press and fix the fourth high-speed line group that passes through the second opening into the connecting groove 1.2 onto the fourth pressure area 4.7 on the lower surface of the PCB board 4 at intervals on the side of the third pressure area 4.5 away from the mounting section, so as to fix the solder ends of each high-speed line of the fourth high-speed line group below the fourth soldering area 4.8 between the third pressure area 4.5 and the fourth pressure area 4.7 on the lower surface of the PCB board 4.

[0056] By setting the third clamping structure 14 and the fourth clamping structure 15, the third high-speed line group is first pressed and fixed onto the second clamping area 4.3 on the upper surface of the PCB board 4 using the third pressure plate 14.2, so that the soldering ends of each high-speed line of the third high-speed line group are fixed above the second soldering area 4.4 on the upper surface of the PCB board 4. Then, the soldering of each high-speed line of the third high-speed line group on the second soldering area 4.4 is completed, thus completing the soldering of a layer of high-speed lines (i.e., the third high-speed line group) on the upper surface of the PCB board 4. Then, the first high-speed line group is pressed and fixed onto the first clamping area 4.1 on the upper surface of the PCB board 4 using the first pressure plate 2.2, so that the soldering ends of each high-speed line of the first high-speed line group are fixed above the first soldering area 4.2 on the upper surface of the PCB board 4. Then, the soldering of each high-speed line of the first high-speed line group is completed. By welding the end on the first welding area 4.2, the welding of the high-speed line layer (i.e., the first high-speed line group) on the upper surface of the PCB board 4 away from the PCB board 4 can be completed, thereby completing the welding of the two high-speed lines (i.e., the third high-speed line group close to the PCB board 4 and the first high-speed line group away from the PCB board 4) on the upper surface of the PCB board 4. The welding of the two high-speed lines (i.e., the fourth high-speed line group close to the PCB board 4 and the second high-speed line group away from the PCB board 4) on the lower surface of the PCB board 4 is carried out in the same way. In the whole welding process, the two pressing and welding do not interfere with each other, and the operation is simple. This allows the welding fixture of the high-speed connector provided by the present invention to adapt well to and simplify the welding process of the PCB board 4, which needs to weld two layers of high-speed lines on both sides (upper surface and lower surface) (the welding areas corresponding to each layer of high-speed lines are arranged at intervals along the X-axis direction).

[0057] Preferably, in this embodiment, such as Figures 1 to 5 As shown, a third limiting buckle 16 is hinged to the upper surface of the positioning section, and a fourth limiting buckle 17 is hinged to the lower surface of the positioning section. A third tension spring 18 is connected between one end of the third limiting buckle 16 and the upper surface of the positioning section. The third limiting buckle 16 is used to press and limit the third rotating rocker arm 14.1 on the upper surface of the positioning section when the third rotating rocker arm 14.1 is flipped to fit the upper surface of the positioning section, so that the third pressure plate 14.2 presses and fixes the third high-speed wire group on the second pressure area 4.3. A fourth tension spring 19 is connected between one end of the fourth limiting buckle 17 and the lower surface of the positioning section. The fourth limiting buckle 17 is used to press and limit the fourth rotating rocker arm 15.1 on the lower surface of the positioning section when the fourth rotating rocker arm 15.1 is flipped to fit the lower surface of the positioning section, so that the fourth pressure plate 15.2 presses and fixes the fourth high-speed wire group on the fourth pressure area 4.7.

[0058] The high-speed connector welding fixture provided by this invention introduces a third locking mechanism consisting of a third limiting buckle 16 and a third tension spring 18, and a fourth locking mechanism consisting of a fourth limiting buckle 17 and a fourth tension spring 19. When the third rotating rocker arm 14.1 flips to the upper surface of the fitting positioning section, causing the third wire pressing plate 14.2 to press and fix the third high-speed wire group onto the second pressing area 4.3 on the upper surface of the PCB board 4, the third limiting buckle 16 can be pulled by the third tension spring 18. The third rotary rocker arm 14.1 is automatically or manually pressed and limited on the upper surface of the positioning section. When the fourth rotary rocker arm 15.1 flips to fit the lower surface of the positioning section, causing the fourth pressure plate 15.2 to press and fix the fourth high-speed line group on the fourth pressure area 4.7 in the lower surface of the PCB board 4, the fourth limit buckle 17 can automatically or manually press and limit the fourth rotary rocker arm 15.1 on the lower surface of the positioning section under the tension of the fourth tension spring 19, forming a stable self-locking structure. This ensures that during the soldering process, even with slight vibration or accidental contact, the third pressure plate 14.2 and the fourth pressure plate 15.2 will not loosen and will always maintain the pressure on the third and fourth high-speed line groups.

[0059] The first, second, third, and fourth locking mechanisms all utilize spring force for locking and unlocking, making operation extremely simple. Operators only need to overcome the spring force to pry open the corresponding latch to release the rotating rocker arm, or press the rotating rocker arm under the corresponding latch to complete the locking process. This design eliminates the need for complex locking components (such as screws or latches), simplifying operation and improving production efficiency.

[0060] Preferably, in this embodiment, such as Figures 1 to 6 As shown, the third limiting buckle 16 is hinged to the upper surface of the positioning section in a rotatable manner around the X-axis, and the fourth limiting buckle 17 is hinged to the lower surface of the positioning section in a rotatable manner around the X-axis. The third limiting buckle 16 has a third slot 16.1 at one end facing the third rotating rocker arm 14.1, which corresponds to the third locking platform 14.1.1 protruding on the side of the third rotating rocker arm 14.1; The fourth limiting buckle 17 is provided with a fourth slot at one end facing the fourth rotating rocker arm 15.1, which corresponds to the fourth locking platform 15.1.1 protruding on the side of the fourth rotating rocker arm 15.1.

[0061] The connection structures between the first limiting buckle 10 and the first rotating rocker arm 2.1, the second limiting buckle 11 and the second rotating rocker arm 3.1, the third limiting buckle 16 and the third rotating rocker arm 14.1, and the fourth limiting buckle 17 and the fourth rotating rocker arm 15.1 are similar. In this invention, the connection structure between the third limiting buckle 16 and the third rotating rocker arm 14.1 is given as an example (e.g., Figure 6 (As shown).

[0062] Preferably, in this embodiment, such as Figure 2 and Figure 4 As shown, a third torsion spring 14.3 is provided at the hinge end of the third rotating rocker arm 14.1. The third torsion spring 14.3 is used to drive the third rotating rocker arm 14.1 to flip away from the positioning section when the third limiting buckle 16 releases the pressing limit on the third rotating rocker arm 14.1. The hinge end of the fourth rotating rocker arm 15.1 is provided with a fourth torsion spring 15.3. The fourth torsion spring 15.3 is used to drive the fourth rotating rocker arm 15.1 to flip away from the positioning section when the fourth limit buckle 17 releases the pressing limit on the fourth rotating rocker arm 15.1.

[0063] By setting the first torsion spring 2.3, the second torsion spring 3.3, the third torsion spring 14.3, and the fourth torsion spring 15.3, the welding fixture of the high-speed connector provided by this invention allows the spring force of the torsion springs to automatically spring open the rotating rocker arms after the locking of the first rotating rocker arm 2.1, the second rotating rocker arm 3.1, the third rotating rocker arm 14.1, and the fourth rotating rocker arm 15.1 is released, causing them to flip to the side away from the positioning section. This design eliminates the need for operators to manually lift the rotating rocker arms, and the efficiency improvement is even more significant when dealing with multiple rotating rocker arms. The operation process is simplified to simply releasing the latch, and the corresponding rotating rocker arm automatically springs open, achieving semi-automatic operation.

[0064] Preferably, in this embodiment, such as Figures 1 to 5 As shown, a magnetic suction structure 20 is provided on the side of the positioning section away from the installation section for attracting the mounting base plate 1 together with the clamping fixture that holds the first high-speed line group, the second high-speed line group, the third high-speed line group and the fourth high-speed line group.

[0065] The welding fixture for the high-speed connector provided by this invention has at least the following technical effects or advantages: 1. The welding fixture for the high-speed connector provided by the present invention achieves positioning and fixing of the PCB board 4 installed in the positioning groove 1.1 by using a positioning clamping mechanism. The first high-speed wire group, which enters the positioning groove 1.1 from the first opening, is pressed and fixed to the upper surface of the PCB board 4 by using the first clamping structure 2 and the second clamping structure 3 respectively, and the second high-speed wire group, which enters the connecting groove 1.2 from the second opening, is pressed and fixed to the lower surface of the PCB board 4. This simultaneously achieves positioning and fixing between the PCB board 4 and the first high-speed wire group to be welded to the upper surface of the PCB board 4, and between the PCB board 4 and the second high-speed wire group to be welded to the lower surface of the PCB board 4. The welding device is formed by the slot on the upper surface of the positioning section of the positioning groove 1.1, which welds the first high-speed wire group to the PCB board. The gun inlet channel on the upper surface of 4, through the opening of the connecting groove 1.2 on the lower surface of the positioning section, forms a welding device to weld the second high-speed line group to the gun inlet channel on the lower surface of the PCB board 4; thus, when the welding fixture of the high-speed connector provided by the present invention is used to weld the PCB board 4 which needs to be welded to both sides (upper and lower surfaces), only one fixture is needed, and the entire welding process can be completed in one assembly and disassembly. It has the advantages of high welding efficiency, low fixture cost, simple and quick operation, and high clamping efficiency. It solves the technical problems of low welding efficiency, high fixture cost, complicated operation, low clamping efficiency, and easy damage to the high-speed lines welded at one time when using the existing high-speed connector welding fixture to weld the PCB board 4 which needs to be welded to both sides (upper and lower surfaces).

[0066] 2. When using the welding fixture for the high-speed connector provided by this invention to weld the PCB board 4 to the first high-speed line group and the PCB board 4 to the second high-speed line group, since the first high-speed line group and the second high-speed line group are respectively pressed and fixed on the upper surface of the PCB board 4 by the first pressure plate 2.2 and the second pressure plate 3.2 pressed and fixed on the lower surface of the PCB board 4, the operator (or automated welding equipment) can quickly and accurately perform welding without repeatedly adjusting or manually holding the high-speed lines during the welding process, directly improving welding efficiency. At the same time, the fixed position ensures the consistency of the welding points, reduces defects such as cold solder joints and short circuits, and significantly improves welding quality, especially suitable for precision welding scenarios with high requirements for signal transmission quality, such as high-speed lines.

[0067] 3. By placing the PCB board 4 at the bottom of the positioning groove 1.1, the PCB board 4 can be directly positioned in the Z-axis direction. By setting the first positioning block 6 and the second positioning block 7, the PCB board 4 can be quickly positioned in the X-axis direction by using the first positioning block 6 in cooperation with the first anti-foolproof positioning groove 1.1 and the second positioning block 7 in cooperation with the second anti-foolproof positioning groove 1.1. The second side of the PCB board 4 in the Y-axis direction is pressed against the second side wall of the positioning groove 1.1 in the Y-axis direction by the first elastic component 5, so that the second side wall can be used as the positioning surface to complete the rapid positioning of the PCB board 4 in the Y-axis direction. This makes the welding fixture of the high-speed connector provided by the present invention simple and quick in positioning and fixing the PCB board 4, with high clamping efficiency and high positioning accuracy. At the same time, since the clamping force provided by the first elastic component 5 is flexible, it can adapt to the small differences in the size of the PCB board 4 in the Y-axis direction, ensuring stable clamping while avoiding damage to the corners or stress concentration of the PCB board that may be caused by using rigid clips.

[0068] 4. By setting the second elastic component 8 to press the first positioning block 6 and the second positioning block 7 onto the inner walls of the first and second anti-foolproof positioning grooves 1.1 respectively, it can not only eliminate the positioning error of the PCB board 4 in the X-axis direction caused by the fit gap between the first positioning block 6 and the first anti-foolproof positioning groove 1.1, and the fit gap between the second positioning block 7 and the second anti-foolproof positioning groove 1.1, but also enhance the positioning reliability of the PCB board 4 in the positioning groove 1.1, ensuring that the PCB board 4 will not easily loosen even with slight vibration or accidental contact during the soldering process. At the same time, since the clamping force provided by the second elastic component 8 is flexible, it can adapt to the slight differences in the size of the PCB board 4 in the X-axis direction, ensuring stable clamping while avoiding damage to the corners or stress concentration of the PCB board that may be caused by using rigid clips.

[0069] 5. By setting the pressure block 9, it can be ensured that when the first high-speed line group is pressed and fixed on the upper surface of the PCB board 4 by the first pressure plate 2.2 to complete the positioning between the first high-speed line group and the PCB board 4, the pressure block 9 can press the upper surface of the PCB board 4, forcing the lower surface of the PCB board 4 to fit with the bottom of the positioning groove 1.1. This not only improves the positioning accuracy of the PCB board 4 in the Z-axis direction, but also prevents the PCB board 4 from warping due to the pressure applied by the first pressure plate 2.2 and the second pressure plate 3.2.

[0070] 6. The welding fixture for the high-speed connector provided by the present invention introduces a first locking mechanism consisting of a first limiting buckle 10 and a first tension spring 12, and a second locking mechanism consisting of a second limiting buckle 11 and a second tension spring 13. When the first rotating rocker arm 2.1 is flipped to fit the upper surface of the positioning section, so that the first wire pressing plate 2.2 presses and fixes the first high-speed wire group on the upper surface of the PCB board 4, the first limiting buckle 10 can automatically or manually press and limit the first rotating rocker arm 2.1 on the upper surface of the positioning section under the tension of the first tension spring 12. When the second rotating rocker arm 3.1 is flipped to fit the lower surface of the positioning section, so that the second wire pressing plate 3.2 presses and fixes the second high-speed wire group on the lower surface of the PCB board 4, the second limiting buckle 11 can automatically or manually press and limit the second rotating rocker arm 3.1 on the lower surface of the positioning section under the tension of the second tension spring 13, forming a stable self-locking structure. This ensures that during the welding process, even with slight vibration or accidental contact, the first pressure plate 2.2 and the second pressure plate 3.2 will not loosen and will always maintain tight pressure on the first and second high-speed wire groups.

[0071] 7. By setting the third clamping structure 14 and the fourth clamping structure 15, the third high-speed line group is first pressed and fixed on the second clamping area 4.3 on the upper surface of the PCB board 4 using the third pressure plate 14.2, so that the soldering ends of each high-speed line of the third high-speed line group are fixed above the second soldering area 4.4 on the upper surface of the PCB board 4. Then, the soldering of each high-speed line of the third high-speed line group on the second soldering area 4.4 is completed, thus completing the soldering of a layer of high-speed lines (i.e., the third high-speed line group) on the upper surface of the PCB board 4. Then, the first pressure plate 2.2 is used to press and fix the first high-speed line group on the first clamping area 4.1 on the upper surface of the PCB board 4, so that the soldering ends of each high-speed line of the first high-speed line group are fixed above the first soldering area 4.2 on the upper surface of the PCB board 4. Then, the soldering of each high-speed line of the first high-speed line group is completed. The welding at the first welding area 4.2 completes the welding of the high-speed line layer (i.e., the first high-speed line group) on the upper surface of the PCB board 4 away from the PCB board 4, and then completes the welding of the two high-speed lines (i.e., the third high-speed line group close to the PCB board 4 and the first high-speed line group away from the PCB board 4) on the upper surface of the PCB board 4. The welding of the two high-speed lines (i.e., the fourth high-speed line group close to the PCB board 4 and the second high-speed line group away from the PCB board 4) on the lower surface of the PCB board 4 is done in the same way. In the whole welding process, the two pressing and welding do not interfere with each other, and the operation is simple. This allows the welding fixture of the high-speed connector provided by the present invention to adapt well to and simplify the welding process of the PCB board 4, which needs to weld two layers of high-speed lines on both sides (upper surface and lower surface) (the welding areas corresponding to each layer of high-speed lines are arranged at intervals along the X-axis direction).

[0072] 8. The welding fixture for the high-speed connector provided by the present invention introduces a third locking mechanism consisting of a third limiting buckle 16 and a third tension spring 18, and a fourth locking mechanism consisting of a fourth limiting buckle 17 and a fourth tension spring 19; when the third rotating rocker arm 14.1 flips to the upper surface of the fitting positioning section, so that the third wire pressing plate 14.2 presses and fixes the third high-speed wire group on the second pressing area 4.3 in the upper surface of the PCB board 4, the third limiting buckle 16 can be pulled by the third tension spring 18. The third rotary rocker arm 14.1 is automatically or manually pressed and limited on the upper surface of the positioning section under force. When the fourth rotary rocker arm 15.1 flips to fit the lower surface of the positioning section, so that the fourth pressure plate 15.2 presses and fixes the fourth high-speed line group on the fourth pressure area 4.7 in the lower surface of the PCB board 4, the fourth limit buckle 17 can automatically or manually press and limit the fourth rotary rocker arm 15.1 on the lower surface of the positioning section under the tension of the fourth tension spring 19, forming a stable self-locking structure. This ensures that during the soldering process, even with slight vibration or accidental contact, the third pressure plate 14.2 and the fourth pressure plate 15.2 will not loosen and will always maintain the pressure on the third and fourth high-speed line groups.

[0073] 9. The first, second, third, and fourth locking mechanisms all utilize spring force for locking and unlocking, making operation extremely simple. Operators only need to overcome the spring force to pry open the corresponding latch to release the rotating rocker arm, or press the rotating rocker arm under the corresponding latch to complete the locking process. This design eliminates the need for complex locking components (such as screws or latches), simplifying operation and improving production efficiency.

[0074] 10. By setting the first torsion spring 2.3, the second torsion spring 3.3, the third torsion spring 14.3, and the fourth torsion spring 15.3, the welding fixture of the high-speed connector provided by this invention allows the spring force of the torsion springs to automatically spring open the rotating rocker arms after the locking of the first rotating rocker arm 2.1, the second rotating rocker arm 3.1, the third rotating rocker arm 14.1, and the fourth rotating rocker arm 15.1 is released, causing them to flip to the side away from the positioning section. This design eliminates the need for operators to manually lift the rotating rocker arms, and the efficiency improvement is more significant, especially when dealing with multiple rotating rocker arms. The operation process is simplified to releasing the buckle, and the corresponding rotating rocker arm automatically springs open, realizing semi-automatic operation. The automatically spring-opening rotating rocker arm will stay in a position away from the working area, providing unobstructed space for removing the soldered PCB board 4 and placing new PCB boards 4 and wires, avoiding damage to the soldered wires or PCB boards 4 due to forgetting to lift the rocker arm or improper operation.

[0075] 11. The engagement of the card slots and card platforms (i.e., the engagement of the first card slot with the corresponding first card platform 2.1.1, the engagement of the second card slot with the corresponding second card platform 3.1.1, the engagement of the third card slot 16.1 with the corresponding third card platform 14.1.1, and the engagement of the fourth card slot with the corresponding fourth card platform 15.1.1) provides clear mechanical feedback (such as a slight click or tactile feel) when locking, allowing operators to intuitively determine whether the rocker arm has been locked in place, thus avoiding clamping failure due to incomplete locking.

[0076] 12. When the welding fixture and the wire clamping fixture are connected via a connecting key, the magnetic attraction structure 20 (such as a magnet) generates an attractive force, guiding the two fixtures to fit together quickly and accurately. This reduces the difficulty of alignment for the operator and improves the efficiency of fixture assembly. The magnetic attraction provides a continuous and flexible holding force for the connection of the two fixtures. It ensures that the two fixtures remain tightly fitted during the welding operation and will not accidentally detach due to vibration or wire tension, thus enhancing the stability of the entire fixture system.

[0077] The above are merely specific application examples of the present invention and do not constitute any limitation on the scope of protection of the present invention. All technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of protection of the present invention.
