[0001] The present invention relates to the technical field of electrical connection element processing, and in particular to a connector welding auxiliary jig. Background Art

[0002] Connectors are often called connectors, generally referring to electrical connectors, which are electronic devices used to connect two active devices for current or signal transmission and are widely used in existing electronic circuit systems.

[0003] When connectors are processed and produced in the prior art, the pins of the connectors need to be welded to the cables inside the cable. In order to ensure the accuracy of the welding of the connector pins at both ends of the cable and the cables and avoid deviations in the cable welding connections, the cables inside the cable are usually specially marked. For example, multiple cables of different colors are used for welding, and the welding pins of the connectors on both sides are paired according to the colors of the cables. This processing method is suitable for situations where there are fewer connector pins. If there are too many connector pins, a large number of cables of different colors are required to assist in pairing during welding.

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0042] Embodiment: This embodiment provides a connector welding auxiliary jig, see Figure 1 - Fig.11 Specifically, it includes a host 1 and a disk 2. A touch display screen 101 is fixedly installed on the top of the host 1. A USB socket 102, a slave interface 103, a to interface 104 and a common terminal 105 are fixedly installed on the host 1. A slave adapter line 106 is plugged into the slave interface 103, a to interface 104 is plugged into the to adapter line 107, and a metal sheet 108 is plugged into the common terminal 105. A welding fixture 3 is installed on the disk 2, and the welding fixture 3 includes a first bearing plate 301 installed on the disk 2, two symmetrically arranged first clamping plates 302 are slidably installed on the first bearing plate 301, a first stud bolt 303 is rotatably installed on the first bearing plate 301, and both ends of the first stud bolt 303 are respectively threadedly screwed with the two first clamping plates 302, the two first clamping plates 302 are used to clamp the ends of the slave adapter line 106 and the to adapter line 107, and the metal sheet 108 is installed on the welding fixture 3.

[0043] When the jig is in use, the USB socket 102 is used to plug in a U disk, which can be used to import source data. A storage module is provided in the host 1, which has a data storage function and is used to store data of different cable electrical relationships. The slave interface 103 and the to interface 104 are both composed of two 64-core bull-horn sockets, and the common end 105 is composed of a banana socket. The staff can control the jig through the touch display screen 101. With the assistance of the jig, the operation of welding the cable between the two connectors is completed. One end of the slave adapter 106 is adapted to the 64-core bull-horn socket on the slave interface 103, and the other end of the slave adapter 106 is adapted to the connector to be welded. One end of the to adapter 107 is adapted to the 64-core bull-horn socket on the to interface 104, and the other end of the slave adapter 106 is adapted to another connector to be welded. When assisting welding, The staff can use the welding fixture 3 to clamp the slave adapter line 106 or the to adapter line 107. The thread directions of the two ends of the first stud bolt 303 are opposite. When the staff holds the first stud bolt 303 and rotates it, the two symmetrically arranged first clamping plates 302 can be driven to synchronously approach or move away from each other by means of the threaded connection between the two ends of the first stud bolt 303 and the two first clamping plates 302 on both sides, so that the slave adapter line 106 or the to adapter line 107 is firmly clamped between the two symmetrically arranged first clamping plates 302. Since the connector is plugged into the outer end of the slave adapter line 106 or the to adapter line 107 during welding, when the slave adapter line 106 and the to adapter line 107 are fixed, the connector plugged therein also remains in a stable state, which is convenient for the staff to accurately weld the cables in the cable to the welding feet of the connector.

[0044] Taking welding of two 9-core connectors as an example, slave adapter wire 106 and to adapter wire 107 are respectively plugged into slave interface 103 and to interface 104, and the other ends of slave adapter wire 106 and to adapter wire 107 are respectively adapted to the two 9-core connectors. When welding, the staff first imports the data of the cable electrical relationship through a U disk, wherein the import format of data ① is in Excel format, reflecting the electrical relationship of the cable, the port code, and the cable color; the import content of data ② is a schematic diagram of the solder pin position of the connector, requiring the highlight of the soldered point to be displayed in real time or the hollow to be changed to solid; the data format is determined by the engineer based on technical feasibility; the connector models in data ① and data ② are associated, and the operation interface is displayed on the touch screen 101; when the corresponding port code is selected in the operation interface, the corresponding connector graphic diagram will be displayed.

[0045] The staff fixes the outer end of the slave adapter cable 106 by means of the welding fixture 3, and then arbitrarily selects a 9-core connector as the first welding target and plugs it into the outer end of the slave adapter cable 106. At this time, the staff can arbitrarily connect the 9 cables on the same end of the cable to the 9 welding pins on the first 9-core connector one by one for blind welding, and there is no need to use the system installed in the host 1 during this process.

[0046] When the welding of the first 9-core connector and the cable is completed, the staff performs welding operation on the second 9-core connector. The staff fixes the outer end of the adapter line 107 by welding fixture 3, and plugs the second 9-core connector into the outer end of the adapter line 107. In this state, the first 9-core connector that has been welded before is still plugged into the slave adapter line 106. The staff randomly selects any one of the cables and first connects it to the metal sheet 108. At this time, the signal output from the interface 103 is connected through the connection between the slave adapter line 106 and the first 9-core connector, and with the help of the connection between the cable and the metal sheet 108, a loop is formed. The host 1 can detect the loop and display it on the touch screen. The pins corresponding to the loop are displayed on the screen 101. The touch screen 101 displays two schematic diagrams of the 9-pin connectors on the left and right. The left schematic diagram corresponds to the slave interface 103, and the right schematic diagram corresponds to the destination interface 104. When the pins of the first 9-pin connector plugged into the slave adapter 106 form a closed loop through the overlap of the cable and the metal sheet 108, the corresponding pins on the left schematic diagram will be lit up. Then the staff will weld the cable to the corresponding welding foot on the second 9-pin connector according to the lit position. When the welding point is correct, the corresponding pins on the left and right schematics will be lit synchronously. The above operation is repeated to gradually complete the welding operation of 9 cables and 9 pins of the second 9-pin connector.

[0047] During the welding process of connectors, the jig can be used to assist workers in finding the cables corresponding to the pins between the two connectors accurately and efficiently. There is no need to specially mark or record the cables. The operation is convenient and helps to improve the welding efficiency of workers when processing connectors.

[0048] In the specific implementation process, Figure 2 , Figure 3 and Figure 7 - Figure 8As shown, the disc 2 is arranged upright, a shaft cylinder 201 is fixedly installed at the axial position of the back side of the disc 2, and a back plate 202 is rotatably installed behind the shaft cylinder 201, and a base 203 is installed at the bottom of the back plate 202. There are two welding fixtures 3, which are symmetrically arranged on the upper and lower sides of the front side of the disc 2. The ends of the slave transfer line 106 and the to transfer line 107 are respectively clamped between two first clamping plates 302 symmetrically arranged in the upper and lower welding fixtures 3. When the fixture is used, since a welding fixture 3 is respectively arranged on the upper and lower sides of the disc 2, the two welding fixtures 3 can be used for clamping the slave transfer line 106 and the to transfer line 107, respectively, which makes it unnecessary for the staff to frequently disassemble the slave transfer line 106 and the to transfer line 107 for welding. Replacement makes the welding auxiliary operation more convenient. By setting the disc 2 to a vertical state, the connector can be inserted into the outer end of the adapter line 106 or the adapter line 107 and clamped in the welding fixture 3 below. The welding feet of the connector can be exposed upward, which can effectively improve the convenience of the staff when welding the welding feet. The disc 2 is rotated on the front of the shaft cylinder 201 through the shaft cylinder 201, so that the upper and lower welding fixtures 3 can be replaced by the rotation of the disc 2, and the welding feet of the first connector and the second connector before and after the replacement are both exposed upward. The reason why the two welding fixtures 3 are not arranged side by side is because this can avoid mutual interference when the two connectors are welded side by side, which improves the convenience of operation of the fixture in actual use to a certain extent.

[0049] In the specific implementation process, Figure 4 , Figure 6 and Fig. 9 As shown, the back plate 202 is rotatably connected to the base 203, the back of the back plate 202 is hinged with a round rod 204, and the end of the round rod 204 is rotatably installed with a screw sleeve 205, the screw sleeve 205 is internally threaded with a screw rod 206, and the end of the screw rod 206 is hinged to the top of the base 203, and a counterweight block 207 is fixed on the base 203. When the jig is used, the round rod 204, the screw sleeve 205 and the screw rod 206 constitute a support structure hinged between the back plate 202 and the base 203. By rotating the back plate 202 to the base 203 and cooperating with the threaded connection between the screw sleeve 205 and the screw rod 206, the jig can be Flexible adjustment: the staff can rotate the screw sleeve 205 according to the operating habits during actual use, and flexibly adjust the actual length of the screw sleeve 205 and the screw rod 206 by means of the threaded connection between the screw sleeve 205 and the screw rod 206, so as to adjust the inclination angle of the back plate 202, so as to adjust the inclination angle of the disc 2 in the upright state. Through flexible adjustment, the operating comfort of the staff when using the device to frequently weld connectors can be effectively improved. By fixing the counterweight block 207 on the base 203, the center of gravity of the device can be effectively lowered, which is beneficial to improve the structural stability of the disc 2 after adjustment to different inclination angles.

[0050] In the specific implementation process, Figure 4 , Figure 8 and Fig.10 - Fig.11 As shown, the back of the first carrier plate 301 is hinged to the disc 2, and a second carrier plate 304 corresponding to the first carrier plate 301 is fixedly installed on the disc 2, and a symmetrically arranged first spring sheet 305 is installed on the second carrier plate 304, and the metal sheet 108 is fixedly embedded on the front end wall of the second carrier plate 304. When the jig is used, since the first carrier plate 301 is hinged to the disc 2, the staff can adjust the outer end of the slave adapter line 106 or the to-switch line 107 clamped between the two first clamping plates 302 to a state where the socket faces straight forward by rotating the first carrier plate 301, which makes it convenient for the staff to plug the connector into the outer end of the slave adapter line 106 or the to-switch line 107, and to install it after welding is completed. The connector is pulled out from the outer ends of the adapter wire 106 and the adapter wire 107. During welding, the staff can press the first carrier plate 301 toward the disk 2 through the hinge of the first carrier plate 301 and the disk 2, so that the first carrier plate 301 fits against the front end wall of the disk 2, and cooperates with the restriction of the first spring sheet 305 symmetrically arranged on the second carrier plate 304 to ensure the stability of the position of the first carrier plate 301. In this state, under the clamping of the two first clamping plates 302 and the elastic engagement of the two first spring sheets 305, the outer ends of the adapter wire 106 and the adapter wire 107, as well as the connector are in an upright state parallel to the front of the disk 2, which is convenient for the staff to perform welding processing and is flexible in operation, which can further improve the convenience of the staff when using the jig.

[0051] In the specific implementation process, Figure 5 As shown, two symmetrically arranged second clamping plates 306 are slidably installed in the second supporting plate 304, and a second stud bolt 307 is rotatably installed on the second supporting plate 304, and the two ends of the second stud bolt 307 are respectively threadedly screwed with the two second clamping plates 306, and the two first spring sheets 305 are respectively fixedly installed on the two second clamping plates 306. When the jig is used, the staff can flexibly adjust the positions of the two first spring sheets 305 according to the size of the welded connector. The threads at the two ends of the second stud bolt 307 are in opposite directions. The staff can hold the second stud bolt 307 and rotate it. With the help of the threaded engagement between the two ends of the second stud bolt 307 and the second clamping plates 306 on both sides, the second clamping plates 306 on both sides are driven to synchronously approach each other or synchronously move away from each other, thereby adjusting the positions of the second clamping plates 306 on both sides, and then adjusting the positions of the first spring sheets 305 fixed on the second clamping plates 306 on both sides, so that the jig can adapt to and engage connectors of different sizes. Through flexible adjustment, the scope of application of the device can be improved to a certain extent.

[0052] In the specific implementation process, Figure 7 As shown, a turntable 4 is rotatably installed at the axial position of the front side of the disc 2, and two symmetrically arranged winding posts 401 are fixedly installed on the front side of the turntable 4, a worm wheel 402 coaxially arranged therewith is fixed around the outer side of the turntable 4, a worm 403 meshing with the worm wheel 402 is rotatably installed on the disc 2, a protective ring 404 movably sleeved on the outer side of the turntable 4 is fixedly installed on the front side of the disc 2, and symmetrically arranged U-shaped grooves 405 are opened on the upper and lower end walls of the protective ring 404, and a second spring sheet 406 is fixedly installed on the inner end wall of the U-shaped groove 405. During the use of the fixture, when the cable welded between the two connectors is too long, in order to ensure the stability of welding, the staff can drive the turntable 4 to rotate, drive the two winding posts 401 fixed on the turntable 4 to rotate, and reel up the overlong cable. The toggle rod of the worm 403 extends to the outside of the disc 2. During actual operation, the staff will The long cable is inserted into the U-shaped groove 405 opened on the upper and lower end walls of the protective ring 404. The restriction of the second spring sheet 406 can prevent the cable from easily escaping from the U-shaped groove 405, and the middle position of the cable is inserted between the two winding posts 401. Then, the staff can turn the worm 403 to rotate, and drive the worm wheel 402 to drive the turntable 4 to rotate with the help of the meshing connection between the worm 403 and the worm wheel 402, so as to provide power for the rotation of the two winding posts 401. The cable is wound around the two winding posts 401 in an orderly manner through rotation, and only a small amount of length is reserved on the upper and lower sides for welding. In the process of driving the turntable 4 to rotate, the meshing of the worm 403 and the worm wheel 402 is used for one-way transmission, so as to realize the self-locking of the turntable 4 after being driven to rotate, so as to prevent the cable from being loosened after being wound on the two winding posts 401, which is conducive to ensuring the stability of the fixture during actual operation.

[0053] In the specific implementation process, Figure 4 and Fig. 9As shown, a latch 5 pointing to the back of the disc 2 is slidably inserted on the back plate 202, and a straight spring 501 is sleeved on the outer side of the latch 5. One end of the back side of the straight spring 501 is elastically supported on the back plate 202, and one end of the front side of the straight spring 501 is fixedly connected to the latch 5. Two grooves 502 corresponding to the latch 5 are provided on the back end wall of the disc 2. The two grooves 502 are symmetrically arranged along the central axis. When the jig is used, the elastic support of the front end of the latch 5 by the straight spring 501 makes the front end of the straight spring 501 maintain a tendency to move forward, and in the absence of external force, it is always tightly abutted against the back of the disc 2, and the front end of the latch 5 is inserted into the groove 502. The disc 2 is restricted in rotation by the inner ring. When the disc 2 needs to be rotated to replace the positions of the upper and lower welding fixtures 3, the staff can pull the pin 5 backwards so that the front end of the pin 5 withdraws from the groove 502. At this time, the disc 2 can rotate normally. After the positions of the upper and lower welding fixtures 3 are replaced, the staff releases the pulling of the pin 5, and with the help of the elastic support of the straight spring 501, the front end of the pin 5 is reinserted into the other groove 502 to complete the re-locking of the disc 2. The disc 2 can rotate only when the positions of the upper and lower welding fixtures 3 are replaced, which can effectively ensure the stability of the staff when using the jig to assist in welding the connector.

[0054] In the specific implementation process, Figure 4 , Figure 6 and Figure 8 - Fig. 9 As shown, the upper and lower side end walls of the disc 2 are provided with a first through slot 6, the back plate 202 is provided with a second through slot 601 adapted to the first through slot 6, the shaft cylinder 201 is fixedly provided with a first stop block 602, and the back plate 202 is fixedly provided with a second stop block 603 adapted to the first stop block 602. When the jig is used, the adapter line 106 and the adapter line 107 can be inserted into the shaft cylinder 201 through the first through slot 6 and the second through slot 601, and the adapter line 107 can be inserted into the shaft cylinder 201 from the rear of the back plate 202. The lead-out prevents the adapter wire 106 and the to adapter wire 107 from swinging randomly when the disc 2 rotates. At the same time, the rotation angle of the disc 2 is limited by fixing the first limit block 602 and the second limit block 603 that adapt to each other on the shaft tube 201 and the back plate 202 respectively, so that the disc 2 can only rotate 180° forwards and backwards, thereby preventing the disc 2 from rotating too much and causing the adapter wire 106 and the to adapter wire 107 to be entangled, which is beneficial to improving the operational stability of the fixture when it is used.

[0055] Specifically, the working principle and operation method of the present invention are as follows:

[0056] Insert the U disk into the USB socket 102, import the source data, select the corresponding port code on the touch screen 101 according to the model of the connector and cable, and display the graphical diagram of the connector, fix the outer end of the slave adapter line 106 between the two first clamping plates 302 in the lower welding fixture 3, fix the outer end of the to adapter line 107 between the two first clamping plates 302 in the upper welding fixture 3, flip the first carrier plate 301 over so that the sockets at the outer ends of the slave adapter line 106 and the to adapter line 107 face the front, plug the two connectors into the outer ends of the slave adapter line 106 and the to adapter line 107 respectively, flip the first carrier plate 301 in the opposite direction, and with the help of two symmetrical A spring sheet 305 engages the connector, so that the outer ends of the adapter wire 106 and the adapter wire 107, as well as the connector, remain fixed, and the cable is inserted into the U-shaped groove 405 opened on the upper and lower outer end walls of the protective ring 404, and is restricted by the second spring sheet 406, and the middle position of the cable is inserted between the two winding posts 401, and then the worm 403 is driven to rotate, and the winding post 401 is driven to rotate by the engagement of the worm 403 and the worm wheel 402, and the overlong cable is wound on the two winding posts 401 in an orderly manner, leaving only a certain length on the upper and lower sides for welding. The staff first connects the cable to the connector plugged from the outer end of the adapter wire 106 below The staff can perform the foot welding operation at will, and implement blind welding without special identification of the cables. After the blind welding is completed, the staff pulls the pin 5 backward to release the restriction on the disc 2, and drives the disc 2 to rotate 180°, so that the upper and lower welding fixtures 3 are replaced. At this time, the connector plugged into the outer end of the adapter line 107 is at the bottom. After the position is adjusted, the pull on the pin 5 is released, and the disc 2 is re-restricted. Then the staff performs the welding operation on the connector plugged into the adapter line 107. At this time, the staff randomly selects any cable in the cable and first overlaps it on the metal sheet 108. The signal output from the interface 103 passes through the plug-in from the adapter line 106 and the connector, and with the help of the cable The overlap with the metal sheet 108 forms a loop, and the host 1 can detect the loop and display the pins corresponding to the loop on the touch screen 101. The pins corresponding to the schematic on the touch screen 101 are lit up, and then the staff welds the cable to the corresponding welding pins of the connector plugged into the outer end of the adapter cable 107 according to the lit position. When the welding point is correct, the corresponding pins on the two schematics on the touch screen 101 will be lit synchronously, and the above operation is repeated to gradually complete the welding operation of multiple cables in the cable and the connector plugged into the outer end of the adapter cable 107. After the welding is completed, the staff removes the cable and the connectors at both ends, and rotates the disk 2 in the opposite direction to reset it.

[0057] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
