Description

Technical Field

[0001] The invention relates to the technical field of plug plugging and unplugging testing, in particular to a plug plugging and unplugging testing device. Background Art

[0002] The main purpose of the plug insertion and extraction test is to evaluate the performance and life of plugs and connectors during repeated insertion and extraction, to ensure that they can maintain stable connection and transmission performance during long-term use. Through the test, it is possible to detect whether the plugs and connectors are loose, have poor contact, etc., thereby avoiding equipment failure or damage caused by this.

[0003] In the use of existing plug-in and plug-out test equipment, the plug and the socket are fixed on two clamps respectively. When the plug and socket are plugged in and out of the test, the friction between the plug and the socket is large, and the two clamps will shake when the plug is inserted and pulled out. When the experiment time is long, the shaking of the clamps will cause the two clamps to deviate from their initial positions, which will affect the accuracy of the plug when it is inserted into the socket. For this reason, we propose a plug-in and plug-out test equipment. Summary of the invention

As the ball rolls, the lubricating oil can be lubricated on the surface of the ball, ensuring that the ball is always in a lubricated state when the positioning rod moves.

[0022] Specifically, refer to Figure 7 and Fig. 9The auxiliary component 13 includes a ball 14. A uniformly distributed mounting groove 15 is provided on one side of the fixed block 11 close to the positioning rod 12. The ball 14 is rotatably arranged in the mounting groove 15. The inner bottom of the mounting groove 15 rolls with the outer side of the ball 14. A symmetrically distributed auxiliary hole 16 is provided on the inner side of the mounting groove 15. A connecting hole 17 is provided between the two auxiliary holes 16. An oil storage bin 18 is provided in the fixed block 11. An oil outlet hole 19 is provided in the middle of the connecting hole 17. The oil outlet hole 19 is connected to the oil storage bin 18. An oil filling hole 20 closed by a fixing bolt is provided on the side of the oil storage bin 18. The principle of the auxiliary component 13 reducing the friction force of the positioning rod 12 during movement: first, when the drive box 5 is inserted into the socket with the plug on the mounting seat 6, the positioning rod 12 moves with the mounting seat 6, and the positioning rod 12 squeezes the ball 14 in the fixed block 11, so that the ball 14 rotates during the movement of the positioning rod 12, thereby reducing the friction force of the positioning rod 12 when it moves in the fixed block 11, and further reducing the vibration generated when the plug and the socket are plugged in and out.

[0023] At the same time, reference Figure 7 and Fig. 9 In order to ensure that the ball 14 is always lubricated when the positioning rod 12 moves, a slider 21 is slidably provided in the auxiliary hole 16, and the outer side of the slider 21 is sealed and connected to the inside of the auxiliary hole 16. A stopper 22 is fixedly provided at one end of the slider 21 close to the mounting groove 15, and a compression spring 23 is fixedly provided at one end of the slider 21 away from the mounting groove 15. The compression spring 23 is fixedly connected to the inside of the auxiliary hole 16, and the outer diameter of the stopper 22 is smaller than the inner diameter of the auxiliary hole 16; The mounting groove 15 is provided with an auxiliary groove 24, and the two ends of the auxiliary groove 24 are respectively connected to the two auxiliary holes 16 in the mounting groove 15; It is worth noting that Figure 5 and Figure 6 As shown, a slide rail 38 cooperating with the ball 14 is fixedly provided on one side of the positioning rod 12 close to the fixing block 11, and the fixing block 11 does not contact the slide rail 38, thereby ensuring that the positioning rod 12 moves straight and stably; When the positioning rod 12 is inserted between the two fixed blocks 11, the positioning rod 12 squeezes the ball 14 in the fixed block 11 and squeezes the ball 14 into the inside of the mounting groove 15. At this time, the ball 14 presses the push rod 22, pressing the push rod 22 into the auxiliary hole 16, so that the slider 21 blocked at the connection between the auxiliary hole 16 and the connecting hole 17 is pushed away by the pressure rod. At this time, the lubricating oil in the oil storage tank 18 is injected into the connecting hole 17 through the oil outlet hole 19, and then enters the auxiliary hole 16. As the ball 14 rotates in the mounting groove 15, the lubricating oil forms an oil film at the auxiliary groove 24, and the oil film gradually wraps around the rolling ball 14, thereby ensuring that the ball 14 always remains lubricated when the positioning rod 12 moves between the fixed blocks 11.

[0024] In the present technical solution, when the positioning rod 12 leaves the ball 14, under the action of the compression spring 23, the slider 21 re-blocks the connection between the auxiliary hole 16 and the connecting hole 17, and the ball 14 is also pressed against the opening of the mounting groove 15 under the action of the push rod 22, preventing the lubricating oil from accidentally leaking from the corresponding mounting groove 15 when the ball 14 is not in use.

[0025] In this technical solution, if Figure 4 As shown, the clamping assembly 17 includes a positive and negative screw rod 25, which is rotatably arranged in the mounting seat 6, one end of the positive and negative screw rod 25 passes through the mounting seat 6 and is fixed with a handle 126, and two clamping plates 13 are provided, the two clamping plates 13 are symmetrically arranged in the mounting seat 6, and the two clamping plates 13 are symmetrically arranged on the positive and negative screw rod 25 and are threadedly connected with the positive and negative screw rod 25; Among them, a screw rod 27 is symmetrically arranged on the outer side of the mounting seat 6, and the screw rod 27 is threadedly connected to the mounting seat 6. A handle 28 is fixedly arranged on the outer end of the screw rod 27, and a pressure plate 29 that fits with the clamping plate 3 is fixedly arranged on the inner end of the screw rod 27; The principle of clamping and fixing the plug by the clamping assembly 7 is as follows: first, place the plug between the two clamping plates 3, and rotate the positive and negative screw rods 25 by means of the handle 26 to drive the two clamping plates 3 to move toward each other to clamp the plug, and then rotate the screw rod 27 by means of the handle 28 to push the pressure plate 29 toward the clamping plate 3, so as to use the pressure plate 29 to assist in clamping the outer side of the clamping plate 3, thereby improving the clamping effect of the clamping plate 3 on the plug.

[0026] In this technical solution, if Figure 3 As shown, the clamping assembly 10 includes a screw rod 30, which is threadedly disposed on the top of the support seat 8, a handle 31 is fixedly disposed on the top of the screw rod 30, and the bottom end of the screw rod 30 is rotatably connected to the clamp plate 4, which is slidably disposed in the support seat 8; The principle of the clamping assembly 2 10 clamping the socket is as follows: first, the socket is placed on the support plate 9 , and then the screw 2 30 is rotated by the handle 3 31 to drive the pressure plate 29 2 to move downward, and the pressure plate 29 2 is used to fix the socket on the support plate 9 .

[0027] In this technical solution, if Figure 3 and Figure 8 As shown, an auxiliary frame 32 is fixedly provided on the top of the mounting frame 2, a fixed cylinder 33 is fixedly provided inside the auxiliary frame 32, a piston plate 34 is slidably provided inside the fixed cylinder 33, the outer side of the piston plate 34 is sealedly connected to the inner side of the fixed cylinder 33, a piston rod 35 is fixedly provided on one side of the piston plate 34, the piston rod 35 penetrates the fixed cylinder 33 and is fixed to the output end of the drive box 5, a connecting pipe 36 is fixedly provided on the end of the fixed cylinder 33 away from the piston rod 35, a nozzle 37 is fixedly provided on the auxiliary frame 32, the connecting pipe 36 is fixedly connected to the nozzle 37, and the end of the nozzle 37 away from the connecting pipe 36 is arranged on the outer side of the socket clamped at the second clamp plate 4; Among them, Figure 2 As shown, one end of the nozzle 37 away from the connecting pipe 36 faces the inside of the socket clamped at the second clamping plate 4; When the mounting base 6 drives the plug to move toward the socket, the mounting base 6 drives the piston plate 34 to slide in the fixed cylinder 33 through the piston rod 35, pushing the air in the fixed cylinder 33 into the connecting tube 36, and then pushing it into the nozzle 37 through the connecting tube 36, and finally spraying the air into the socket through the nozzle 37 to clean the dust in the socket and ensure the accuracy of the data measured during the plug insertion and extraction experiment.

[0028] In this scheme, first, the plug is placed between the two clamping plates 3, and the positive and negative screw rods 25 are rotated by the handle 26 to drive the two clamping plates 3 to move toward each other to clamp the plug, and then the screw rod 27 is rotated by the handle 28 to push the pressure plate 29 toward the clamping plate 3, so that the pressure plate 29 is used to assist in clamping the outer side of the clamping plate 3, thereby improving the clamping effect of the clamping plate 3 on the plug; Then, place the socket on the support plate 9, and then rotate the screw rod 2 30 by the handle 3 31 to drive the pressing plate 29 2 to move downward, and use the pressing plate 29 2 to fix the socket on the support plate 9, at this time, the plug and the socket are coaxial; Afterwards, the drive box 5 is started through the operating table 1, and the drive box 5 is used to push the mounting seat 6 to push the plug toward the socket. At this time, the positioning rod 12 slides between the two fixed blocks 11, and the positioning rod 12 presses the ball 14 inside the mounting groove 15 through the ball 14 to press the pressure rod, and then the slider 21 is pushed away from the slider 21 at the connection between the auxiliary hole 16 and the connecting hole 17 by the pressure rod. The lubricating oil in the oil storage tank 18 is injected into the connecting hole 17 through the oil outlet hole 19, and then enters the auxiliary hole 16. As the ball 14 rotates in the mounting groove 15, the lubricating oil forms an oil film at the auxiliary groove 24, and the oil film gradually wraps around the rolling ball 14, thereby ensuring that the ball 14 always keeps a lubricated state when the positioning rod 12 moves between the fixed blocks 11. Since the fixed block 11 does not contact the positioning rod 12, the friction force of the positioning rod 12 when it moves in the fixed block 11 can be reduced, thereby reducing the vibration effect generated when the plug is plugged in and out. When the mounting base 6 drives the plug to move toward the socket, the mounting base 6 drives the piston plate 34 to slide in the fixed cylinder 33 through the piston rod 35, pushing the air in the fixed cylinder 33 into the connecting tube 36, and then pushing it into the nozzle 37 through the connecting tube 36, and finally spraying the air into the socket through the nozzle 37 to clean the dust in the socket and ensure the accuracy of the data measured during the plug insertion and extraction experiment.

[0029] Embodiment 2: This embodiment further explains the embodiment 1, and the difference lies in the optimization of the first clamping plate 3 and the second clamping plate 4; Specifically, arc grooves may be provided on the inner surfaces of the clamping plate 1 3 and the clamping plate 2 4 that are in contact with the plug and the socket, so as to ensure that the plug and the socket are in a coaxial state when clamped.
