Description

Technical Field

[0001] The present invention relates to the field of jigs, and specifically to a pneumatic suction jig. Background Art

[0002] In the electronic manufacturing industry, before products leave the factory, they need to be tested to ensure that users can purchase safe, qualified and high-quality products. Among the electronic products used by people, the quantity of mobile electronic products is large, and the quantity of their supporting products is also large. There is a kind of supporting data cable product, which is used for charging and data transmission of electronic products. Before this data cable leaves the factory, it also needs to undergo various performance tests, and various test jigs are used in the tests.

[0003] There is a jig for testing data cables. Before the data cables leave the factory, each data cable needs to be tested for power connection to ensure the qualification rate of the data cables. The existing testing method is to test each data cable one by one manually. By holding the plug part of the data cable and pushing it into the jack, and observing the test screen, the qualified products are classified as factory products, and the unqualified products are sent back for repair or remanufacture.

[0004] However, this method of frequent repetitive operations will inevitably cause wear or frictional damage to the finger part. At the same time, when the finger pinches and inserts, the plug cannot be accurately inserted into the jack every time. When it abuts against the shell of the test device, the reaction force of the data cable plug causes secondary damage to the finger.

[0005] Therefore, in view of the above problems, a pneumatic suction jig is proposed. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, the present invention proposes a pneumatic suction jig.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: An air-operated suction jig described in the present invention includes a bottom plate. On one side of the bottom plate, a fixed block is provided. On one end face of the fixed block, a jack for testing is opened. At the other end of the fixed block, a conductive wire is connected, and the conductive wire is connected to the pin inserted into the jack. On the other side of the bottom plate, a pushing unit is provided. The pushing unit includes a moving block. A groove penetrating through the front and back is opened at the middle position of the moving block. Symmetrically fixed to the lower end of the moving block are traction blocks. The traction blocks slide through the sliding holes opened on the lower plate of the bottom plate and are fixedly connected to the output ends of cylinders. The cylinders are fixedly connected to the lower surface of the bottom plate. At the rear end of the groove, baffles are symmetrically provided. On the inner surface of the groove, suction ports are opened. The suction ports are communicated with the pipe bodies provided on the side walls of the traction blocks. In the embodiment of the present invention, by designing an air-operated suction jig for testing data lines, the labor of operators is reduced, and finger abrasion and pain are avoided. The operator places the end of the data line, that is, the plug part of the data line, in the groove. At this time, the surface of the plug seals the suction port, and the negative pressure in the suction port is responsible for being executed by an external negative pressure pump. When the plug is placed in the groove, the suction port sucks the plug and horizontally places the plug in the groove. At the same time, the rear end of the plug faces the baffle. Then, the cylinder is driven. The cylinder drives the moving block to move through the traction block and move towards the fixed block. At the same time, the baffle pushes the plug into the jack. Then, the display screen on the fixed seat shows the qualified condition of the data line. After that, the cylinder resets. At this time, the plug is still inserted in the jack. The operator only needs to slightly pull the data line with force to take out the plug from the jack, and the pulling force is not enough to damage the data line. In the above process, only by placing the plug in the groove and the suction port adsorbs the plug to make the plug stable. Compared with the existing method of pinching the plug with fingers and pushing it forcefully into the jack, the jig provided in the present invention can avoid the phenomenon of finger pain caused by pushing the plug into the jack with force, and at the same time reduce the finger fatigue brought by the frequent repeated operations of the operator.

[0008] Preferably, a slot is provided at the middle position of the inner surface of the groove. An adsorption plate is provided in the groove. Suction ports are opened on the adsorption plate. A plug tube is provided on the lower surface of the adsorption plate. The plug tube is communicated with the suction port and is inserted into the slot. There are various types of data lines, and the shapes of the plugs are also various, so that the shapes and sizes of the insulating layers on the outer surfaces of the plugs are various. The suction ports at a single position in the groove cannot adapt to various types of plugs. Therefore, according to the types of data lines produced by the manufacturer, the adsorption plate provided in the groove can be replaced. Different positions of suction ports are opened on the adsorption plate, and the adsorption plate is selected according to the type of data line. Remove the screws fixing the adsorption plate, replace the adsorption plate, insert the plug tube on the lower surface of the adsorption plate into the slot, and connect the external pipe body to the suction port on the adsorption plate. At this time, when the data line is placed in the groove, the plug can be adsorbed and fixed.

[0009] Preferably, rotation grooves are symmetrically formed in the rear end face of the groove, one end of a baffle is rotatably connected in the rotation groove, the other ends of the baffles are oppositely arranged, fixing holes are formed in the end surface of the baffle, fixing rods are inserted in the fixing holes, the fixing rods slidably penetrate through to the upper end surface of the moving block, and are elastically and limitedly connected through springs; the baffle is arranged to block the removal and installation of the adsorption plate. Therefore, the baffle is arranged to be rotatable. When replacing the adsorption plate, the fixing rod is lifted, and the fixing rod disengages from the fixing hole in the baffle. At this time, the baffle can be rotated. The baffle is rotated to the rear end of the moving block. At this time, there is no obstacle at the notch of the groove, and the adsorption plate can be easily replaced. After replacement, the baffle is rotated back to its original position, and the fixing rod is inserted into the fixing hole again through the spring to fix the baffle.

[0010] Preferably, concave openings are formed in the two vertical side walls of the groove, guide grooves are symmetrically formed on both sides in the concave openings, a limiting block is arranged in each concave opening, both ends of the limiting block are slidably connected in the guide grooves, a screw rod is rotatably connected to the middle position of the limiting block, the end of the screw rod is threadedly connected to the moving block and penetrates outside the moving block; the width of the outer insulating wrapping layer of the plug is not easy. For testing data cables of the same batch, in order to place the plug in the middle position of the groove and ensure that the plug is inserted into the jack smoothly and accurately, the screw rod is rotated to push the limiting block, so that the two limiting blocks move synchronously towards the middle of the groove and fit against the outer surface of the plug, and the plug is placed in the middle position of the groove.

[0011] Preferably, inclined surfaces are formed on the opposite side walls of the two limiting blocks, rectangular grooves are formed at the inclined surface positions, and a rod body is rotatably connected in the rectangular grooves; by forming inclined surfaces on the side walls of the limiting blocks, the space for the data cable plug to be placed in the groove is increased, which is convenient for the plug to be placed. At the same time, a rod body is arranged on the inclined surface, so that the plug can smoothly rub the rod body and slide into the groove, preventing the edge of the plug from abutting against the inclined surface, which is helpful for the placement of the plug.

[0012] Preferably, telescopic holes are symmetrically formed on both sides of the jack, guide rods are slidably connected in the telescopic holes, and the end of the first guide rod is fixedly connected to the moving block; by arranging the guide rods, when the moving block moves, the guide rods move deeper into the telescopic holes, making the moving path of the moving block more stable, ensuring that the end of the plug can be smoothly inserted into the jack, and preventing the end of the plug from being scratched against the edge of the jack due to the unstable movement of the moving block, resulting in wear of the edge of the plug or the edge of the jack.

[0013] Preferably, a guide hole is provided on one side of each of the telescopic holes, and a push rod is slidably connected in the guide hole, the push rod passes through one end face of the fixed block, and the ends of two adjacent push rods are fixedly connected to the push plate; when the guide rod is pushed toward the telescopic hole, the inner end of the guide rod is connected to the push rod through the plate body, so that the push rod moves toward the guide hole, and the plug is inserted into the socket at this time. After the test is completed, the moving block is reset and drives the guide rod to reset. At the same time, the guide rod pushes the push rod through the plate body to move out of the guide hole, that is, the moving block, the guide rod and the push rod move synchronously, and the push rod is pushed to the flat part of the end of the plug through the push plate, and the plug is pushed out of the socket, that is, the moving block, the guide rod, the push rod and the plug move synchronously at this time, and then the plug is taken out. The cooperation of the push rod and the guide rod ensures that the data cable does not need to be pulled off manually after the test is completed, and can be pushed out through the push plate, which is convenient for operation again and reduces labor.

[0014] Preferably, a guide plate is provided on the upper edge of the other end of the fixed block, the end of the guide plate extends toward the moving block, and the guide plate includes a horizontal portion, an arc-shaped portion and a tilted portion, the horizontal portion is fixed to the fixed block by bolts, the convex surface of the arc-shaped portion is set toward the setting, and the tilted portion is set inclined upward; by setting the guide plate, downward pressure is applied to the plug to ensure that the plug is stably attached to the adsorption plate; after the plug is placed in the groove, the cable of the data line is in a sagging state to prevent the cable's own gravity from pressing down on the plug and pulling the plug down and tilting it, and a guide plate is provided for this purpose, and when the plug moves toward the jack, the guide plate presses down the plug, that is, the arc-shaped portion presses down the surface of the plug, so that the plug is restricted, further ensuring that the plug is stably adsorbed in the groove.

[0015] Preferably, an observation port is provided at the horizontal position of the guide plate, and an anti-friction pad is attached to the raised surface of the arc-shaped portion; by providing the anti-friction pad, the raised portion of the arc-shaped portion is prevented from wearing the surface of the plug, and the anti-friction pad can be used together with the setting of the observation port to facilitate observation of the movement of the plug, so as to quickly and clearly know whether the plug is accurately inserted into place.

[0016] Preferably, a fixing pin is symmetrically fixed to the concave position of the arc-shaped portion, and the elastic band at the edge of the anti-friction pad passes around the observation port and is sleeved on the fixing pin; after the anti-friction pad is used many times, the anti-friction pad will be worn by friction and lose its anti-wear effect, and must be replaced in time. For this purpose, a fixing pin and an anti-friction pad with an elastic band are provided to facilitate the removal and installation of the anti-friction pad without delaying the testing efficiency of the data cable.

[0017] Preferably, a notch is formed at a position on the inner edge of the observation port close to the fixing pin, and notches are also formed on both sides of the edge of the upturned portion, and the elastic band is embedded in the notch; when the anti-friction pad rubs against the surface of the plug, the back-and-forth movement of the same plug causes the anti-friction pad to shift and disengage from the arc portion. Therefore, the notch is provided to restrict the movement of the elastic band on the guide plate and also restrict the anti-friction pad, so that the anti-friction pad can be stable on the arc portion and ensure the anti-wear effect on the surface of the plug.

[0018] Preferably, a layer of anti-friction layer is bonded to the surface of the adsorption plate and the surface of the limiting block; by providing the anti-friction layer, when the plug is placed into the groove, it can avoid rubbing dents on the smooth surface of the plug, while ensuring the quality qualification rate of the product, it also protects its appearance.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. Through the structural design of the pushing unit, the present invention places the plug in the groove, and the suction port adsorbs the plug to make the plug stable. Compared with the existing method of pinching the plug with fingers and pushing it forcefully into the jack, the jig provided in the present invention can avoid the phenomenon of finger pain caused by pushing the plug into the jack with force, and at the same time reduce the finger fatigue caused by the frequent repeated operations of the operator.

[0021] 2. Through the structural design of the guide rod and the push rod, the moving block, the guide rod, the push rod and the plug move synchronously, and then the plug is taken out. The cooperation of the push rod and the guide rod enables the data cable to be pushed out by the push plate without being manually pulled off after the test, which is convenient for operation again and reduces the labor force.

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1:

[0038] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, A pneumatic suction fixture, including a bottom plate 1. On one side of the bottom plate 1, a fixed block 2 is provided. On one end face of the fixed block 2, a jack 3 for testing is opened. At the other end of the fixed block 2, a conductive wire is connected, and the conductive wire is connected to the pin inside the jack 3; on the other side of the bottom plate 1, a pushing unit is provided. The pushing unit includes a moving block 4. A through groove 5 is opened in the middle position of the moving block 4. Symmetrically fixed at the lower end of the moving block 4 are traction blocks. The traction blocks slide through the sliding holes opened in the lower plate of the bottom plate 1 and are fixedly connected to the output ends of cylinders 6. The cylinders 6 are fixedly connected to the lower surface of the bottom plate 1; symmetrically provided at the rear end of the groove 5 are baffles 7. Suction ports 8 are opened on the inner surface of the groove 5. The suction ports 8 are communicated with a pipe body 9 provided on the side wall of the traction block; in the embodiment of the present invention, by designing a fixture for pneumatically sucking and testing data lines, the labor of operators is reduced, and finger abrasion and pain are avoided; the operator places the end of the data line, that is, the plug part of the data line, in the groove. At this time, the surface of the plug seals the suction port 8, and the negative pressure in the suction port 8 is responsible for being executed by an external negative pressure pump. When the plug is placed in the groove 5, the suction port 8 sucks the plug and horizontally places the plug in the groove 5. At the same time, the rear end of the plug faces the baffle 7. Then, the cylinder 6 is driven. The cylinder 6 drives the moving block 4 to move through the traction block and move towards the fixed block 2. At the same time, the baffle 7 pushes the plug into the jack 3. Then, the display screen on the fixed seat shows the qualified condition of the data line. After that, the cylinder 6 resets. At this time, the plug is still inserted in the jack 3. The operator only needs to slightly pull the data line with force to take out the plug from the jack 3, and the pulling force is not enough to damage the data line; in the above process, only the plug needs to be placed in the groove 5, and the suction port 8 adsorbs the plug to make the plug stable. Compared with the existing method of pinching the plug with fingers and pushing it into the jack 3 forcefully, the fixture provided in the present invention can avoid the phenomenon of finger pain caused by pushing the plug into the jack 3 with force, and at the same time reduce the finger fatigue caused by the operator's frequent repeated operations.

[0039] Refer to Figure 3 , Figure 5 and Figure 6 , A slot 12 is provided in the middle position of the inner surface of the groove 5. An adsorption plate 10 is provided in the groove 5. Suction ports 8 are opened on the adsorption plate 10. A plug tube 11 is provided on the lower surface of the adsorption plate 10. The plug tube 11 is communicated with the suction port 8. The plug tube 11 is inserted in the slot 12; there are various types of data lines, and the shapes of the plugs are also various, so that the shapes and sizes of the insulating layers on the outer surfaces of the plugs are various. The single-position suction port 8 in the groove 5 cannot adapt to various types of plugs. Therefore, according to the type of data line produced by the manufacturer, the adsorption plate 10 provided in the groove 5 can be replaced; different positions of suction ports 8 are opened on the adsorption plate 10, and the adsorption plate 10 is selected according to the type of data line; remove the screw fixing the adsorption plate 10, replace the adsorption plate 10, insert the plug tube 11 on the lower surface of the adsorption plate 10 into the slot 12, and the external pipe body 9 is communicated with the suction port 8 on the adsorption plate 10. At this time, when the data line is placed in the groove 5, the plug can be adsorbed and fixed.

[0040] Refer to Figure 1 and Figure 9 As shown in FIGS. Figure 1 and Figure 9 , symmetrically arranged rotation grooves 13 are formed in the rear end face of the groove 5. One end of a baffle 7 is rotatably connected within the rotation groove 13, and the other ends of the baffles 7 are oppositely arranged. Fixing holes are formed in the end surface of the baffle 7, and fixing rods 131 are inserted into the fixing holes. The fixing rods 131 slide through to the upper end surface of the moving block 4 and are elastically and limit-connected by springs. The baffle 7 is provided to block the removal and installation of the adsorption plate 10. Therefore, the baffle 7 is set to be rotatable. When replacing the adsorption plate 10, the fixing rod 131 is lifted upwards, and the fixing rod 131 disengages from the fixing hole on the baffle 7. At this time, the baffle 7 can be rotated. The baffle 7 is rotated to the rear end of the moving block 4. At this time, the notch of the groove 5 has no blocking object, and the adsorption plate 10 can be easily replaced. After replacement, the baffle 7 is rotated back to its original position, and the fixing rod 131 is inserted into the fixing hole again through the spring to fix the baffle 7.

[0041] Refer to Figure 2 and Figure 8 As shown in FIGS. Figure 2 and Figure 8 , concave openings are formed in the two vertical side walls of the groove 5. Guide grooves are symmetrically formed on both sides within the concave openings. A limiting block 14 is arranged within each concave opening. Both ends of the limiting block 14 are slidably connected within the guide grooves. A screw rod 15 is rotatably connected to the middle position of the limiting block 14. The end of the screw rod 15 is threadedly connected to the moving block 4 and penetrates outside the moving block 4. The width of the outer insulating wrapping layer of the plug is not easy to control. For testing data cables of the same batch, in order to place the plug in the middle position of the groove 5 to ensure that the plug is smoothly and accurately inserted into the jack 3, the screw rod 15 is rotated to push the limiting block 14, so that the two limiting blocks 14 move synchronously towards the middle of the groove 5 and fit with the outer surface of the plug to a smaller extent, and the plug is placed in the middle position of the groove 5.

[0042] Refer to Figure 8 As shown in FIG. Figure 8 , inclined surfaces are formed on the opposite side walls of the two limiting blocks 14, and rectangular grooves are formed at the inclined surface positions. A rod 16 is rotatably connected within the rectangular grooves. By forming inclined surfaces on the side walls of the limiting blocks 14, the space for placing the data cable plug into the groove 5 is increased, facilitating the insertion of the plug. At the same time, by arranging the rod 16 on the inclined surface, the plug can smoothly rub against the rod 16 and slide into the groove 5, preventing the edge of the plug from abutting against the inclined surface, which helps with the placement of the plug.

[0043] Refer to Figure 2 and Figure 7, telescopic holes are symmetrically provided on both sides of the socket 3, and a guide rod 17 is slidably connected in the telescopic hole, and the end of the No. 1 guide rod 17 is fixedly connected to the moving block 4; by providing the guide rod 17, when the moving block 4 moves, the guide rod 17 moves toward the depth of the telescopic hole, so that the moving path with fast movement is more stable, ensuring that the end of the plug can be smoothly inserted into the socket 3, preventing the end of the plug from scraping against the edge of the socket 3 due to the unstable movement of the moving block 4, causing the edge of the plug to be worn, or the edge of the socket 3 to be worn.

[0044] Reference Figure 2 and Figure 7 A guide hole is provided on one side of each telescopic hole, and a push rod 19 is slidably connected in the guide hole. The push rod 19 penetrates one end surface of the fixed block 2, and the ends of the two adjacent push rods 19 are fixedly connected to the push plate 20; when the guide rod 17 is pushed toward the telescopic hole, the inner end of the guide rod 17 is connected to the push rod 19 through the plate body 171, so that the push rod 19 moves toward the guide hole. At this time, the plug is inserted into the jack 3. After the test is completed, the moving block 4 is reset, and the guide rod 17 is driven to reset. At the same time, the guide rod 17 passes through the plate body 17 1 Push the push rod 19 to move out of the guide hole, that is, the moving block 4, the guide rod 17 and the push rod 19 move synchronously, and the push rod 19 is pushed to the flat part of the end of the plug through the push plate 20, and the plug is pushed out of the socket 3, that is, at this time, the moving block 4, the guide rod 17, the push rod 19 and the plug move synchronously, and then the plug is taken out. The cooperation of the push rod 19 and the guide rod 17 makes it possible for the data cable to be pushed out through the push plate 20 without being manually pulled out after the test, which is convenient for operation again and reduces labor.

[0045] Reference Figure 1 , Figure 10 and Figure 11 A guide plate 21 is provided on the upper edge of the other end of the fixed block 2, and the end of the guide plate 21 extends toward the moving block 4, and the guide plate 21 includes a horizontal portion 22, an arc portion 22 and a tilting portion 23. The horizontal portion 22 is fixed to the fixed block 2 by bolts, and the convex surface of the arc portion 22 is set facing, and the tilting portion 23 is set obliquely upward; by setting the guide plate 21, downward pressure is applied to the plug to ensure that the plug is stably attached to the adsorption plate 10; after the plug is placed in the groove 5, the cable of the data line is in a sagging state to prevent the cable's own gravity from pressing down the plug and pulling the plug down and tilting it, and a guide plate 21 is provided for this purpose. When the plug moves toward the jack 3, the guide plate 21 presses down the plug, that is, the arc portion 22 presses down the surface of the plug, so that the plug is restricted, further ensuring that the plug is stably adsorbed in the groove 5.

[0046] Reference Figure 10 and Figure 11An observation port 24 is provided at the horizontal portion 22 of the guide plate 21, and an anti-friction pad 25 is attached to the raised surface of the arc portion 22; the anti-friction pad 25 is provided to prevent the raised portion of the arc portion 22 from wearing the surface of the plug, and the anti-friction pad 25 can be used together with the setting of the observation port 24 to facilitate observation of the movement of the plug, so as to quickly and clearly know whether the plug is accurately inserted into place.

[0047] Reference Figure 10 , Figure 11 and Figure 12 The concave position of the arc-shaped portion 22 is symmetrically fixed with a fixing pin 26, and the elastic band 27 on the edge of the anti-friction pad 25 bypasses the observation port 24 and is sleeved on the fixing pin 26; after the anti-friction pad 25 is used many times, the anti-friction pad 25 will be worn by friction and lose its anti-wear effect, and it needs to be replaced in time. For this purpose, a fixing pin 26 and an anti-friction pad 25 with an elastic band 27 are provided to facilitate the removal and installation of the anti-friction pad 25 without delaying the testing efficiency of the data line.

[0048] Reference Figure 11 A notch 28 is provided on the inner edge of the observation port 24 near the position of the fixing pin 26, and notches 28 are also provided on both sides of the edge of the raised portion 23, and the elastic band 27 is embedded in the notch 28; when the anti-friction pad 25 rubs against the surface of the plug, the back and forth movement of the same plug causes the anti-friction pad 25 to deviate from the arc-shaped portion 22. For this purpose, a notch 28 is provided to constrain the movement of the elastic band 27 on the guide plate 21, and at the same time, it is also a constraint on the anti-friction pad 25, so that the anti-friction pad 25 can be stabilized on the arc-shaped portion 22, thereby ensuring the anti-wear effect on the plug surface.

[0049] Embodiment 2:

[0050] Comparative Example 1 is another embodiment of the present invention, wherein a friction-proof layer is bonded to the surface of the adsorption plate 10 and the surface of the limit block 14; by providing the friction-proof layer, the smooth surface of the plug can be prevented from being dented by friction when the plug is placed in the groove 5, thereby ensuring the quality pass rate of the product and protecting its appearance.

[0051] Working principle: By designing a fixture for pneumatically sucking and testing data cables, the labor of operators is reduced, and finger abrasion and pain are avoided; the operator places the end of the data cable, that is, the plug part of the data cable, in the groove. At this time, the surface of the plug seals the suction port 8, and the negative pressure in the suction port 8 is executed by an external negative pressure pump. When the plug is placed in the groove 5, the suction port 8 sucks the plug and horizontally places the plug in the groove 5. At the same time, the rear end of the plug faces the baffle 7, and then the driving cylinder 6 is driven. The cylinder 6 drives the moving block 4 to move through the traction block and moves towards the fixed block 2. At the same time, the baffle 7 pushes the plug into the jack 3. Then, the display screen on the fixed seat shows the qualified condition of the data cable. After that, the cylinder 6 resets. At this time, the plug is still inserted in the jack 3. The operator only needs to pull the data cable slightly to take out the plug from the jack 3, and the pulling force is not enough to damage the data cable; in the above process, only the plug needs to be placed in the groove 5, and the suction port 8 adsorbs the plug to make the plug stable. Compared with the existing method of pinching the plug with fingers and pushing it forcefully into the jack 3, the fixture provided in the present invention can avoid the phenomenon of finger pain caused by pushing the jack 3 with force by fingers, and at the same time reduce the finger fatigue caused by the frequent repeated operations of the operator;

[0052] There are various types of data cables, and the shapes of the plugs are also various, so that the shapes and sizes of the outer insulating layers of the plugs are various. The suction ports 8 at a single position in the groove 5 cannot adapt to various types of plugs. Therefore, according to the types of data cables produced by the manufacturer, the adsorption plate 10 arranged in the groove 5 can be replaced; suction ports 8 are opened at different positions on the adsorption plate 10, and the adsorption plate 10 is selected according to the type of data cable; the screws fixing the adsorption plate 10 are removed, the adsorption plate 10 is replaced, the insertion tube 11 on the lower surface of the adsorption plate 10 is inserted into the jack 3, and the external tube 9 communicates with the suction ports 8 on the adsorption plate 10. At this time, when the data cable is placed in the groove 5, the jack 3 can be adsorbed and fixed;

[0053] The setting of the baffle 7 will block the removal and installation of the adsorption plate 10. Therefore, the baffle 7 is set to be rotatable. When replacing the adsorption plate 10, the fixing rod 131 is lifted, and the fixing rod 131 is disengaged from the fixing hole on the baffle 7. At this time, the baffle 7 can be rotated. The baffle 7 is rotated to the rear end of the moving block 4. At this time, there is no obstacle at the notch of the groove 5, and the adsorption plate 10 can be easily replaced. After replacement, the baffle 7 is rotated back to its original position, and the fixing rod 131 is inserted into the fixing hole again through the spring to fix the baffle 7;

[0054] The widths of the outer insulating wrapping layers of the plugs are different. For the test of data cables in the same batch, in order to place the plug in the middle position of the groove 5 to ensure that the plug is inserted into the jack 3 smoothly and accurately, the screw 15 is rotated to push the limit block 14, so that the two limit blocks 14 move synchronously towards the middle of the groove 5 and fit with the outer surface of the plug, and the plug is placed in the middle position of the groove 5;

[0055] By providing an inclined surface on the side wall of the limit block 14, the space for inserting the data line plug into the groove 5 is increased, facilitating the insertion of the plug. At the same time, a rod 16 is provided on the inclined surface, enabling the plug to smoothly rub against the rod 16 and slide into the groove 5, preventing the edge of the plug from abutting against the inclined surface and contributing to the placement of the plug.

[0056] By providing a guide rod 17, when the moving block 4 moves, the guide rod 17 moves deeper into the telescopic hole, making the moving path of the moving block more stable, ensuring that the end of the plug can smoothly insert into the jack 3, and preventing the end of the plug from scraping against the edge of the jack 3 due to the unstable movement of the moving block 4, which may cause wear on the edge of the plug or the edge of the jack 3.

[0057] When the guide rod 17 advances into the telescopic hole, the inner end of the guide rod 17 is connected to a push rod 19 through a plate body 171, causing the push rod 19 to move into the guide hole. At this time, the plug is inserted into the jack 3. After the test is completed, the moving block 4 resets and drives the guide rod 17 to reset. At the same time, the guide rod 17 pushes the push rod 19 through the plate body 171 to move out of the guide hole. That is, the moving block 4, the guide rod 17, and the push rod 19 move synchronously, and the push rod 19 pushes against the flat part of the end of the plug through a push plate 20 and pushes the plug out of the jack 3. That is, at this time, the moving block 4, the guide rod 17, the push rod 19, and the plug move synchronously. Then the plug is removed. The cooperation of the push rod 19 and the guide rod 17 enables the data line to be pushed out through the push plate 20 after the test is completed without the need for manual pulling, which is convenient for operation again and reduces labor.

[0058] By providing a guide plate 21, a downward pressure is exerted on the plug to ensure that the plug is stably attached to the adsorption plate 10. After the plug is placed in the groove 5, the cable of the data line is in a hanging state to prevent the self-weight of the cable from pressing down on the plug and causing the plug to be pulled up. Therefore, the guide plate 21 is provided. When the plug moves towards the jack 3, the guide plate 21 presses down on the plug, that is, the arc-shaped part 22 presses down on the surface of the plug, restricting the plug and further ensuring that the plug is stably adsorbed in the groove 5.

[0059] By providing an anti-friction pad 25, it is possible to prevent the protruding part of the arc-shaped part 22 from wearing the surface of the plug. The anti-friction pad 25 can be used, and the setting of the observation port 24 facilitates observing the movement of the plug, so as to quickly and clearly know whether the plug is accurately inserted in place. After the anti-friction pad 25 is used multiple times, the anti-friction pad 25 will be worn by friction and lose its anti-wear effect, and it needs to be replaced in a timely manner. Therefore, a fixing pin 26 and an anti-friction pad 25 with an elastic band 27 are provided, which facilitates the removal and installation of the anti-friction pad 25 without delaying the test efficiency of the data line.

[0060] When the anti-friction pad 25 rubs against the surface of the plug, the back-and-forth movement of the same plug causes the anti-friction pad 25 to shift away from the arc portion 22. Therefore, a notch 28 is provided to restrict the movement of the elastic band 27 on the guide plate 21, and at the same time, it is also a restriction on the anti-friction pad 25, so that the anti-friction pad 25 can be stabilized on the arc portion 22 to ensure the anti-wear effect on the surface of the plug.
