Description

Technical Field

[0001] This invention relates to the field of cable connector technology, specifically to an auxiliary device for assembling and soldering cables and pads. Background Technology

[0002] The Miniature Eight-Channel Pluggable (QSFP-DD) is a higher dual-density pluggable connector assembly with four channels on the top and four on the bottom. Existing cable connectors typically consist of a mating circuit board, wires connected to the back of the mating circuit board, a chip mounted on the mating circuit board, and a housing encapsulating the mating circuit board. In the QSFP-DD connector, the cable cores are soldered to the circuit board, which is then secured within a shielding housing.

[0003] In the production process of cable connectors, several core wires need to be arranged and soldered onto a circuit board. Conventional core soldering requires fixing the core wires to the circuit board. After soldering, all soldered cables are secured in a corresponding fixing device, and the solder joints are fixed with adhesive gel. However, when using this uniform method to fix and solder cables, since each core wire has different models, when soldering one core wire, it's necessary to consider whether the other core wires on that core are aligned with the conductive plates on the circuit board. This can lead to temporary adjustments to the position of a core wire during the soldering process. Reopening the fixing device at this time can easily cause other soldered core wires to loosen and unsoldered core wires to become misaligned. Furthermore, since cables are usually stored in a coiled state, they are often bent or twisted during use. When the fixed core wires are released, they may retract, moving away from the solder joint, or even multiple core wires may cross over, causing previous steps to fail. Summary of the Invention

These advantages solve the aforementioned problems.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an auxiliary device for welding cables and pads, comprising a circuit board, wherein conductive plates are provided at the middle and end of the circuit board, the conductive plates being used to electrically connect the cables, and a mounting bracket is provided at the end of the conductive plates, the mounting bracket being used to support the cables; a welding auxiliary mechanism is connected above the mounting bracket; the welding auxiliary mechanism includes a movable chuck and a welding auxiliary component, the movable chuck being located above the middle of the mounting bracket, the mounting bracket cooperating with the movable chuck to fix the cables, and the welding auxiliary component being connected to the mounting bracket; the welding auxiliary component includes a movable clamping plate, a leveling clamping plate, and a truss, the truss being connected to both sides of the mounting bracket, the... Both the movable clamp and the leveling clamp are located between the two trusses, and both are detachable. The leveling clamp engages with the upper part of the movable clamp, with one end of the movable clamp supported by the leveling clamp and the other end abutting against the front end of the cable. The welding auxiliary mechanism has two welding auxiliary modes. The first welding auxiliary mode is the overall fixing mode, in which the movable clamp is supported by the leveling clamp at one end and abuts against the front end of the cable at the other end, thus fixing the cable as a whole. The second welding auxiliary mode is the single welding mode, in which the movable clamp and the leveling clamp are disassembled to release the fixation of a single cable, allowing the cable to move.

[0008] Preferably, the cable includes multiple core wires, each core wire consisting of a main conductor core, a secondary conductor core, an insulating shield layer, and an insulating layer.

The bottom of the movable chuck is provided with a positioning groove. The mounting bracket is provided with limiting guide grooves on both sides. The bottom of both sides of the movable chuck is provided with limiting guide rods.

Both the pin holder and the inner side of the truss are provided with mounting protrusions. During the process of the pin holder and the truss being individually combined with the limiting guide rod, the mounting protrusion slides along the mounting groove until the locking block extends into the locking ear.

[0012] Preferably, the movable card plate is composed of multiple movable card plates, each movable card plate corresponding to one of the main conductor wire cores.

The lower surface of the curing clamp plate is close to the distal end of the cable, and the proximal end of the curing clamp plate is located above the movable chuck and engages with the fixed block provided on the upper surface of the movable chuck.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides an auxiliary device for welding cables and pads together, which has the following advantages:

[0018] 1. The auxiliary device for welding cables and pads uses the first-level welding auxiliary mode in the welding auxiliary mechanism to fix the cables as a whole. First, the movable chuck, mounting bracket and welding auxiliary components are installed to fix the cables. Then, the second-level welding auxiliary mode in the welding auxiliary mechanism is used to fix the cables individually. That is, by releasing the fixation of individual cables, the movement of the cables can be facilitated, thereby making it easier to adjust the position of the cables and further weld them.

[0019] 2. This cable and pad welding auxiliary device aligns each cable with the conductive piece on the circuit board, then installs each cable on the corresponding mounting bracket. A movable chuck is then installed above the mounting bracket, with the cable positioned between the movable chuck and the mounting bracket. Further welding auxiliary components are then used to securely connect the movable chuck and the mounting bracket. A truss mounts the movable and leveling chucks above the cable, and the leveling chucks are fixedly connected to the movable chuck, ensuring the leveling chucks are horizontal. The other end of the leveling chuck supports one end of the movable chuck, while the other end of the movable chuck presses against the front end of the cable. With the support of the leveling chuck, the movable chucks are in a fixed position, and the cable is secured by the welding auxiliary components, facilitating the welding of the wire cores.

[0020] 3. The auxiliary device for welding cables and pads uses a movable clamping plate in the movable clamping plate to correspond to a main wire core. When a core wire needs to be adjusted or additional welding is required, one end of the fixed support plate corresponding to that core wire can be detached from the upper part of the movable clamping plate. This allows the fixed support plate to rotate in the middle of the truss, i.e., the fixed support plate rotates downwards on the side of the movable clamping plate and separates from it. One end of the movable clamping plate loses the support of the fixed support plate, i.e., the limiting horizontal plate loses the support of the fixed support plate. The other end of the protective vertical plate can move away from the cable, i.e., the core wire is no longer fixed, but the cable as a whole is still fixed. The middle part of the core wire is still fixed by the movable clamping plate and the mounting bracket. This prevents the core wire from retracting or moving away from the welding point, or even multiple core wires crossing over, which could cause the previous work to fail when the fixed core wire is released due to the cable being bent or twisted.

[0021] 4. The auxiliary device for welding the cable and pads uses a protective clamp plate in the protective vertical plate to hold the main wire core and the auxiliary wire core above it, while a stop plate holds the insulating shielding layer above it. In addition, a fixed support plate supports the other end of the movable clamp plate, so that the movable clamp plate is in a fixed state. When the stop plate is held on the insulating shielding layer, it presses the insulating shielding layer down to the bottom, thereby fixing the far end of the core wire. Since the protective clamp plate is held on top of the main wire core and the auxiliary wire core, it blocks the insulating shielding layer from the back, preventing the heat generated during welding from directly affecting the insulating shielding layer.

[0022] 5. The auxiliary device for welding cables and pads uses a welding curing fixture to apply adhesive to the welded joint between the cable and the conductive sheet after the cable is welded, preventing the circuit board from falling off due to stress after welding. The locking ears on both sides of the clamping bracket in the welding curing fixture, together with the locking blocks on both sides of the limiting guide vertical rod, make the clamping bracket and the mounting bracket merge. The curing clamp, together with the clamping bracket and the mounting bracket, surrounds the far end of the welded cable and the conductive sheet to form an enclosing area, forming the fixture. After the adhesive is applied into the fixture, it forms a cured and solidified adhesive. Attached Figure Description

[0035] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1-11An auxiliary device for welding cables and pads includes a circuit board 1. Conductive plates 11 are provided at the middle and end of the circuit board 1 for electrically connecting the cable 12. A mounting bracket 2 is provided at the end of the conductive plate 11 for supporting the cable 12. A welding auxiliary mechanism is connected above the mounting bracket 2. The welding auxiliary mechanism includes a movable chuck 3 and a welding auxiliary component 4. The movable chuck 3 is located above the middle of the mounting bracket 2, and the mounting bracket 2 cooperates with the movable chuck 3 to fix the cable 12. The welding auxiliary component 4 is connected to the mounting bracket 2. The welding auxiliary component 4 includes a movable clamping strip 41, a leveling clamping strip 42, and a truss 43. The truss 43 is connected to both sides of the mounting bracket 2. The movable clamping strip 41 and the leveling clamping strip... 42 are located between the two trusses 43. The movable clamping plate 41 and the leveling clamping plate 42 are both detachable. The leveling clamping plate 42 is engaged with the upper part of the movable clamping plate 3. One end of the movable clamping plate 41 is limited and supported by the leveling clamping plate 42, and the other end of the movable clamping plate 41 abuts against the front end of the cable 12. The welding auxiliary mechanism has two welding auxiliary modes. The first welding auxiliary mode is the overall fixing mode. One end of the movable clamping plate 41 is limited and supported by the leveling clamping plate 42, and the other end abuts against the front end of the cable 12, so that the movable clamping plate 41 fixes the cable 12 as a whole. The second welding auxiliary mode is the single welding mode. By disassembling the movable clamping plate 41 and the leveling clamping plate 42, the fixation of a single cable 12 is released, so that the cable 12 can move.

[0037] In use, before welding, the first-level welding auxiliary mode in the welding auxiliary mechanism is used to fix the cable 12 as a whole. First, the movable chuck 3 is installed with the mounting base 2 and the welding auxiliary component 4 to fix the cable 12. Specifically, each cable 12 is aligned with the conductive piece 11 on the circuit board 1, and then each cable 12 is installed on the corresponding mounting base 2. Then, the movable chuck 3 is installed above the mounting base 2. At this time, the cable 12 is located between the movable chuck 3 and the mounting base 2. Further, the welding auxiliary component 4 is used to fix the movable chuck 3 and the mounting base 2. The truss 43 installs the movable card plate 41 and the leveling card plate 42 above the cable 12, and the leveling card plate 42 is fixedly connected to the movable chuck 3, that is, the leveling card plate 42 is in a horizontal state. Then, the other end of the leveling bracket 42 supports one end of the movable bracket 41, while the other end of the movable bracket 41 presses against the front end of the cable 12. With the support of the leveling bracket 42, the movable bracket 41 is in a fixed state, that is, the cable 12 is fixed by the welding auxiliary component 4. With the cooperation of the movable chuck 3 and the mounting bracket 2, the cable 12 is fixed on the conductive plate 11, which facilitates the welding of the cable 12 to the conductive plate 11. During the welding process, when individual cables 12 need to be adjusted and then welded, the second-level welding auxiliary mode in the welding auxiliary mechanism is used to fix the cable 12 individually. That is, by releasing the fixation of individual cables 12, the movement of the cable 12 is facilitated, thereby making it easier to adjust the position of the cable 12 and further weld it.

[0038] Furthermore, the cable 12 includes multiple core wires 13, each core wire 13 consisting of a main conductor core 131, a secondary conductor core 132, an insulating shielding layer 133, and an insulating layer 134. The main conductor core 131 and the secondary conductor core 132 are electrically connected to the conductive sheet 11, respectively. The insulating shielding layer 133 is located outside the main conductor core 131, and the secondary conductor core 132 is located on both sides of the main conductor core 131. The insulating layer 134 wraps around the main conductor core 131 and the secondary conductor core 132. The cable 12 is neatly stacked by welding the main conductor core 131 and the secondary conductor core 132 of each core wire 13 to the corresponding conductive sheet 11. Before welding, the insulating layer 134 of each core wire 13 is clamped and arranged by the movable chuck 3 and the mounting bracket 2.

[0039] Furthermore, the middle part of the mounting bracket 2 is directly opposite the distal end of the insulation layer 134 of the cable 12. The tail end of the mounting bracket 2 is provided with a positioning groove 21, and the distal end of the mounting bracket 2 is respectively provided with a protective slot 22 for fixing the insulation shielding layer 133, and a core fixing groove 23 for fixing the main wire core 131 and the auxiliary wire core 132. The cable 12 is initially arranged by the positioning groove 21 provided above the mounting bracket 2. At the same time, the insulation shielding layer 133 of the cable 12 is locked in the corresponding protective slot 22, while the main wire core 131 and the auxiliary wire core 132 are both located in the core fixing groove 23. During welding, the main wire core 131 and the auxiliary wire core 132 of the cable 12 are prevented from being in a state of being suspended, which would cause the distal end of the cable 12 to be raised and inconvenient to weld together with the conductive sheet 11.

[0040] Furthermore, the movable chuck 3 is located above the middle of the mounting base 2 and above the far end of the insulating layer 134. The bottom of the movable chuck 3 is provided with a positioning groove 31. The mounting base 2 is provided with limiting guide grooves 24 on both sides. The bottom of the movable chuck 3 is provided with limiting guide rods 32 on both sides. The limiting guide rods 32 are located inside the limiting guide grooves 24 and are slidably connected to the limiting guide grooves 24. By cooperating with the positioning grooves 21 on the top of the mounting base 2 through the positioning grooves 31 at the bottom of the movable chuck 3, the cable 12 is clamped and arranged after the movable chuck 3 is connected to the mounting base 2. When the movable chuck 3 is installed, the limiting guide rods 32 on both sides of the movable chuck 3 move inside the limiting guide grooves 24 on both sides of the mounting base 2 until the movable chuck 3 and the mounting base 2 are completely in contact.

[0041] Furthermore, the welding auxiliary mechanism also includes a welding curing fixture 5, which includes a clamping bracket 51 located on both sides of the mounting base 2. The clamping bracket 51 locks the movable chuck 3 and the mounting base 2. Both the clamping bracket 51 and the truss 43 have locking lugs 6 at their tail ends. Locking blocks 321 are provided on both sides of the limiting guide vertical rod 32. An installation groove 25 is provided at the far bottom end of the mounting base 2. Installation protrusions 61 are provided on the inner sides of both the clamping bracket 51 and the truss 43. During the individual merging of the clamping bracket 51 and the truss 43 with the limiting guide vertical rod 32, the installation protrusions 61 move along... The mounting groove 25 slides until the locking block 321 extends into the locking ear 6. After the cable 12 is welded, the welding and curing fixture 5 applies adhesive to the welded joint between the cable 12 and the conductive sheet 11 to prevent the circuit board 1 from falling off under stress after welding. The locking ears 6 on both sides of the pin bracket 51 in the welding and curing fixture 5, together with the locking blocks 321 on both sides of the limiting guide rod 32, make the pin bracket 51 merge with both sides of the mounting bracket 2. Then, the pin bracket 51 and the mounting bracket 2 surround the far end of the welded cable 12 and the conductive sheet 11 to form an enclosed area. Then, UV adhesive is applied into the enclosed area, that is, the welding point area between the cable 12 and the conductive sheet 11.

[0042] Furthermore, the movable card plate 41 is composed of multiple movable card plates 411, each movable card plate 411 corresponding to one of the main conductor wire cores 131. The leveling card plate 42 is composed of multiple fixed support plates 421, each fixed support plate 421 corresponding to one of the movable card plates 411. The middle part of the leveling card plate 42 is rotatably connected to the truss 43. One end of the movable card plate 411 is a limiting horizontal plate 412, and the other end of the movable card plate 411 is a protective vertical plate 413. The limiting horizontal plate 412 and the protective vertical plate 413 are arranged perpendicular to each other. One end of the limiting horizontal plate 412 is located above the far end of the rotating shaft of the leveling card plate 42. The middle part of the limiting horizontal plate 412 is connected to the truss 43. The truss 43 is rotatably connected; each movable plate 411 in the movable plate 41 corresponds to a main wire core 131. When a core wire 13 needs to be adjusted or welded, one end of the fixed support plate 421 corresponding to the core wire 13 can be removed from the upper part of the movable plate 3, so that the fixed support plate 421 can rotate in the middle of the truss 43. That is, the fixed support plate 421 is located on the side of the movable plate 411 and rotates downward, separating from the movable plate 411. One end of the movable plate 411 loses the support of the fixed support plate 421, that is, the limiting horizontal plate 412 loses the support of the fixed support plate 421, and the other end of the protective vertical plate 413 can move away from the cable 12, that is, the core wire 13 loses its fixation.

[0043] Furthermore, the other end of the leveling plate 42 is located above the movable chuck 3. Each fixed support plate 421 is provided with a fixed slot 422. The upper surface of the movable chuck 3 is provided with a fixed block 33. The leveling plate 42 is fixed above the movable chuck 3 through the fixed slot 422 and the fixed block 33. Through the fixed slot 422 provided on the fixed support plate 421 and the fixed block 33 provided on the upper surface of the movable chuck 3, the fixed support plate 421 can be horizontally fixed on one side of the movable chuck 3, while the other side of the fixed support plate 421 supports the movable chuck 411, thereby preventing one end of the movable chuck 411 from rotating in the direction of the fixed support plate 421.

[0044] Further, the protective vertical plate 413 includes a protective retaining plate 4131 and a stop plate 4132. The protective retaining plate 4131 is located outside the stop plate 4132 and above the main conductor core 131 and the auxiliary conductor core 132. The stop plate 4132 is located above the insulating shielding layer 133. The upper surface of the mounting bracket 2 is provided with a stop portion 26 when the stop plate 4132 is in the vertical state. The stop portion 26 restricts the tendency of the protective vertical plate 413 to continue rotating towards the insulating shielding layer 133 after it is vertical. The protective plate 411 is positioned above the main conductor core 131 and the auxiliary conductor core 132, while the stop plate 4132 is positioned above the insulating shielding layer 133. Together with the fixed support plate 421, the other end of the movable plate 411 is supported, so that the movable plate 411 is in a fixed state. When the stop plate 4132 is positioned on the insulating shielding layer 133, it presses the insulating shielding layer 133 down to the bottom, thereby fixing the far end of the core wire 13. Since the protective plate 4131 is positioned above the main conductor core 131 and the auxiliary conductor core 132, it blocks the insulating shielding layer 133 from the rear, preventing the heat generated during welding from directly affecting the insulating shielding layer 133.

[0045] Furthermore, the welding curing fixture 5 also includes a curing clamp 52, which is located above the pin bracket 51 and rotatably connected to the distal end of the pin bracket 51. The lower surface of the curing clamp 52 is close to the distal end of the cable 12, and the proximal end of the curing clamp 52 is located above the movable chuck 3 and engages with the fixed block 33 on the upper surface of the movable chuck 3. The curing clamp 52 in the welding curing fixture 5, together with the pin bracket 51 and the mounting bracket 2, surrounds the distal end of the welded cable 12 and the conductive sheet 11 to form an enclosing area, thus forming a fixture. After the glue is injected into the fixture, a curing adhesive is formed.

[0046] Working principle: During use, before welding, the first-level welding auxiliary mode in the welding auxiliary mechanism is used to fix the cable 12 as a whole; firstly, the movable chuck 3, the mounting base 2, and the welding auxiliary component 4 are installed to fix the cable 12; then, each cable 12 is installed on the corresponding mounting base 2 by aligning each cable 12 with the conductive piece 11 on the circuit board 1, and then the main conductor core 131 and the auxiliary conductor core 132 of each core wire 13 are welded to the corresponding conductive piece 11. Before welding, the movable chuck 3... The mounting bracket 2 clamps and arranges the insulation layer 134 of each core wire 13, neatly stacking the cable 12. The positioning groove 21 set above the mounting bracket 2 performs initial arrangement of the cable 12. At the same time, the insulation shielding layer 133 of the cable 12 is stuck inside the corresponding protective groove 22, while the main wire core 131 and the auxiliary wire core 132 are located in the wire core fixing groove 23. During welding, the main wire core 131 and the auxiliary wire core 132 of the cable 12 are prevented from being in a free state, which would cause the far end of the cable 12 to be raised and inconvenient to weld together with the conductive piece 11.

[0047] Then, the movable chuck 3 is installed above the mounting base 2. At this time, the cable 12 is located between the movable chuck 3 and the mounting base 2. The positioning slot 31 at the bottom of the movable chuck 3 cooperates with the positioning slot 21 above the mounting base 2. After the movable chuck 3 and the mounting base 2 are connected, the cable 12 is clamped and arranged. When the movable chuck 3 is installed, the limiting guide vertical rods 32 on both sides of the movable chuck 3 move inside the limiting guide vertical grooves 24 on both sides of the mounting base 2 until the movable chuck 3 and the mounting base 2 are completely in contact.

[0048] Further welding auxiliary components 4 are fixedly connected to the movable chuck 3 and mounting bracket 2. Truss 43 installs the movable clamp 41 and leveling clamp 42 above the cable 12, and the leveling clamp 42 is fixedly connected to the movable chuck 3, meaning the leveling clamp 42 is in a horizontal state. Then, the other end of the leveling clamp 42 supports one end of the movable clamp 41, while the other end of the movable clamp 41 presses against the front end of the cable 12. With the support of the leveling clamp 42, the movable clamp 41 is in a fixed state, meaning the cable 12 is now welded by the auxiliary components. The auxiliary component 4 is fixed; and with the cooperation of the movable chuck 3 and the mounting bracket 2, the cable 12 is fixed on the conductive sheet 11, which facilitates the welding of the cable 12 to the conductive sheet 11; wherein the fixed slot 422 provided on the fixed support plate 421 cooperates with the fixed block 33 provided on the upper surface of the movable chuck 3, so that the fixed support plate 421 can be horizontally fixed on one side of the movable chuck 3, while the other side of the fixed support plate 421 supports the movable chuck plate 411, so that one end of the movable chuck plate 411 cannot rotate in the direction of the fixed support plate 421;

[0049] During the welding process, when individual cables 12 need to be adjusted and then welded, the second-level welding auxiliary mode in the welding auxiliary mechanism is used to fix the individual cables 12. That is, by releasing the fixation of individual cables 12, the movement of the cable 12 is facilitated, thereby making it easier to adjust the position of the cable 12 and then weld it. Each movable plate 411 in the movable plate 41 corresponds to a main wire core 131. When a core wire 13 needs to be adjusted or welded, one end of the fixed support plate 421 corresponding to the core wire 13 can be removed from the upper part of the movable chuck 3. Thus, the fixed support plate 421 can rotate in the middle of the truss 43. That is, the fixed support plate 421 on the side of the movable plate 411 rotates downward and separates from the movable plate 411. One end of the movable plate 411 loses the support of the fixed support plate 421, that is, the limiting horizontal plate 412 loses the support of the fixed support plate 421. The other end of the protective vertical plate 413 can move away from the cable 12, that is, the core wire 13 loses its fixation.

[0050] In the above process: the protective clamping plate 4131 in the protective vertical plate 413 is clamped above the main wire core 131 and the auxiliary wire core 132, while the stop plate 4132 is clamped above the insulating shielding layer 133. In addition, the fixed support plate 421 supports the other end of the movable clamping plate 411, so that the movable clamping plate 411 is in a fixed state. When the stop plate 4132 is clamped on the insulating shielding layer 133, it presses the insulating shielding layer 133 down to the bottom, thereby fixing the far end of the core wire 13. Since the protective clamping plate 4131 is clamped above the main wire core 131 and the auxiliary wire core 132, the insulating shielding layer 133 is blocked behind, so that the heat generated during welding does not directly affect the insulating shielding layer 133.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
