When observing along the path of current flow, one will always find one or more connectors. The form and structure of connectors are ever-changing. There are various forms of connectors depending on the application object, frequency, power, application environment, etc.

[0006] Preferably, the positioning plate a is fixedly arranged on the outside of the electronic connector a, and a slider is arranged at the bottom of the positioning plate a, and the slider slides on the guide plate.

[0007] Preferably, a scale is provided on the outer side of the positioning rod, and a magnetic block is installed on one end of the positioning rod.

[0011] Preferably, the fixing seat is connected to the pull ring via a telescopic spring, a clamping joint is installed at one end of the pull ring, and the clamping joint is clamped with a clamping hole on the clamping plate.

[0012] Preferably, when the piston rod moves following the clamping plate, the piston rod extracts the internal gas of the airbag through the piston cylinder and shrinks the airbag.

[0013] Preferably, a damping rod is provided below the clamping plate for damping sliding, and the magnetic attraction ring is fixedly installed below the magnetic attraction ring.

[0014] Preferably, when one end of the positioning rod moves to the groove above one end of the positioning tube, the magnetic ring is magnetically attracted to the magnetic block on one end of the positioning rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention plays a limiting role through the directional sliding of the positioning plate a on the guide plate and the sliding of the positioning rod inside the positioning tube. Under the cooperation of each other, the connection between the electronic connector a and the electronic connector b can be made more accurate. At the same time, through the scale on the positioning rod, the sliding position of the positioning rod on the positioning tube can be intuitively seen, thereby judging whether the connection degree between the electronic connector a and the electronic connector b is qualified. On the basis of the accurate connection between the electronic connector a and the electronic connector b, the stability of the connection between the electronic connector a and the electronic connector b is further increased, avoiding human judgment errors and deviations in the direction of force, which result in the connection ports of the electronic connector a and the electronic connector b being unable to be accurately plugged in, thereby resulting in poor stability and poor versatility of the connection.

[0017] After the electronic connector a and the electronic connector b are precisely connected, the clamping plate can be pulled, and the clamping plate can drive the piston rod to move, so that one end of the piston rod slides inside the piston cylinder. During the sliding process of the piston rod, the piston rod extracts the gas inside the airbag through the piston cylinder, and the gas inside the airbag will gradually shrink after being extracted. Since the airbag is arranged on the outside of the electronic connector b, it is just at the connection between the electronic connector a and the electronic connector b. After the electronic connector a and the electronic connector b are connected and just wrapped by the airbag, the airbag gradually shrinks and adheres to the electronic connector a and the electronic connector b during the process of the airbag being evacuated. At the connection point, after the clamping plate moves to a certain position, the airbag will be tightly attached to the connection point of the electronic connector a and the electronic connector b, thereby maintaining the sealing effect of the connection point of the electronic connector a and the electronic connector b. On the one hand, the stability of the connection point of the electronic connector a and the electronic connector b can be protected. On the other hand, the connection point of the electronic connector a and the electronic connector b can be sealed, which can prevent the external gas from oxidizing or corroding the connection point of the electronic connector a and the electronic connector b, as well as the infiltration of liquids and even damage caused by solid collisions, thereby further improving the stability of the connection between the electronic connector a and the electronic connector b.

[0018] In the process of pulling the clamping plate to a certain position, the clamping plate drives the damping rod to move, and the damping rod drives the magnetic ring to move along the positioning tube. After the clamping plate moves to a certain position, the magnetic ring moves to the groove on the positioning tube. At this time, the magnetic ring will be magnetically attracted to the positioning rod, so one side of the magnetic ring contacts one side of the positioning rod; in addition, after pulling the clamping plate to a certain position, the pull ring is pulled, and while the pull ring stretches the telescopic spring, the pull ring drives the clamping joint to move until the clamping joint is clamped with the clamping hole on the clamping plate, thereby connecting the clamping plate and the pull ring and keeping them stable. The elastic force generated after the telescopic spring is stretched can make the piston rod and the magnetic ring have a tendency to move in the same direction, and under the tendency of moving in the same direction, the airbag can be kept tight and the connection between the electronic connector a and the electronic connector b can be pre-tightened through the positioning rod.

In the process of the following positioning plate a33 sliding on the guide plate 31 and approaching the electronic connector b2, the positioning rod 36 is inserted into the interior of the positioning cylinder 35 to accurately guide the connection between the electronic connector a1 and the electronic connector b2; the positioning plate a33 is fixedly arranged on the outside of the electronic connector a1, and a slider 37 is arranged at the bottom of the positioning plate a33, and the slider 37 slides on the guide plate 31, and a scale is arranged on the outside of the positioning rod 36, and a magnetic block is installed at one end of the positioning rod 36, a groove is provided above one end of the positioning cylinder 35, a threaded hole is provided on the mounting plate 32, and one side of the mounting plate 32 is rotatably connected to the guide plate 31 through a bearing seat;

[0030] See also Figures 1 to 7 As shown, when the electronic connector a1 and the electronic connector b2 are docked, the slider 37 under the positioning plate a33 is connected to the guide plate 31, so that the positioning plate a33 drives the electronic connector a1 to slide on the guide plate 31, and then pushes the positioning plate a33, so that the positioning plate a33 slides directionally on the guide plate 31 through the slider 37, and at the same time, the electronic connector a1 is moved closer to the electronic connector b2. At the same time, during the sliding process of the positioning plate a33, the positioning plate a33 drives the positioning rod 36 to move, so that the positioning rod 36 is rubbed into the interior of the positioning tube 35, and then the electronic connector a1 and the electronic connector b2 are accurately aligned and plugged, and the positioning plate a33 slides directionally on the guide plate 31, and the positioning rod 36 slides inside the positioning tube 35 to play a limiting role. With the cooperation, the connection between the electronic connector a1 and the electronic connector b2 can be made more accurate. At the same time, through the scale on the positioning rod 36, the sliding position of the positioning rod 36 on the positioning tube 35 can be intuitively seen, thereby judging whether the connection degree between the electronic connector a1 and the electronic connector b2 is qualified. On the basis of the accurate connection between the electronic connector a1 and the electronic connector b2, the stability of the connection between the electronic connector a1 and the electronic connector b2 is further increased, avoiding human misjudgment and deviation in the direction of force, which makes it impossible to accurately plug the connection ports of the electronic connector a1 and the electronic connector b2, resulting in poor connection stability and poor versatility.

[0031] In addition, the mounting plate 32 is rotatably connected to the guide plate 31, and the electronic connector b2 is penetrated by the mounting plate 32, so that the mounting plate 32 can play a wire management role to avoid the wires on the electronic connector b2 from being tangled. At the same time, the electronic connector a1 and the electronic connector b2 can be installed to the required position by using the threaded holes on the mounting plate 32, which is convenient for fixing the electronic connector a1 and the electronic connector b2. In addition, a suction cup can be installed at the bottom of the mounting plate 32 to cope with different installation environments at one time, thereby improving the practicality of the electronic connector a1 and the electronic connector b2.

[0032] The mounting plate 32 is provided with a pre-tightening mechanism 4 for pre-tightening the electronic connector a1 and the connection. The pre-tightening mechanism 4 includes an air bag 41 surrounding the outside of one end of the electronic connector b2. One side of the air bag 41 is connected with a piston cylinder 43 penetrating the positioning plate b34. A piston rod 49 slides inside the piston cylinder 43. One end of the piston rod 49 is fixed with a clamping plate 44 surrounding the outside of the electronic connector b2. A fixing seat 42 is fixed to one side of the mounting plate 32. A telescopic spring 46 is fixed to one end of the fixing seat 42. One end of the telescopic spring 46 is fixed. There is a pull ring 45, one end of the pull ring 45 is clamped with the clamping plate 44, and a magnetic ring 411 is provided below the clamping plate 44 to be magnetically attracted to one end of the positioning rod 36; after the electronic connector a1 and the electronic connector b2 are accurately plugged in, the clamping plate 44 is pulled to make the piston rod 49 slide inside the piston cylinder 43, so that the gas inside the airbag 41 is extracted and the airbag 41 is contracted to cover the connection between the electronic connector a1 and the electronic connector b2; in addition, in the process of pulling the clamping plate 44, the clamping plate 44 is clamped with one end of the positioning rod 36 through the magnetic ring 411. At the same time, when the pull ring 45 is pulled to stretch the telescopic spring 46, the pull ring 45 is engaged with the clamping plate 44 to keep it fixed; one end of the airbag 41 is fixedly installed at the outer edge of the electronic connector b2. After the gas inside the airbag 41 is extracted, the airbag 41 shrinks and is tightly attached to the connection between the electronic connector a1 and the electronic connector b2. The fixing seat 42 is connected to the pull ring 45 through the telescopic spring 46. One end of the pull ring 45 is equipped with a clamping joint 47, which is clamped with the clamping hole on the clamping plate 44. The piston rod 4 In the process of following the movement of the clamping plate 44, the piston rod 49 will extract the gas inside the airbag 41 through the piston cylinder 43 and shrink the airbag 41. The airbag 41 can be made of transparent material, which is convenient for observing the connection between the wrapped electronic connector a1 and the electronic connector b2; the damping rod 410 is provided at the bottom of the clamping plate 44 for damping sliding, and the magnetic ring 411 is fixedly installed at the bottom of the magnetic ring 411. When one end of the positioning rod 36 moves to the groove above one end of the positioning cylinder 35, the magnetic ring 411 is magnetically attracted to the magnetic block on one end of the positioning rod 36;

[0033] See also Figures 3 to 8As shown, after the electronic connector a1 and the electronic connector b2 are precisely connected, the clamping plate 44 can be pulled, and the clamping plate 44 can drive the piston rod 49 to move, so that one end of the piston rod 49 slides inside the piston cylinder 43. During the sliding process of the piston rod 49, the piston rod 49 extracts the gas inside the airbag 41 through the piston cylinder 43. After the gas inside the airbag 41 is extracted, it will gradually shrink. Since the airbag 41 is arranged on the outside of the electronic connector b2, it is just at the connection between the electronic connector a1 and the electronic connector b2. After the electronic connector a1 and the electronic connector b2 are connected and are just wrapped by the airbag 41, the airbag 41 gradually shrinks and adheres to the electronic connector during the process of the airbag 41 being evacuated. At the connection between the electronic connector a1 and the electronic connector b2, after the clamping plate 44 moves to a certain position, the airbag 41 will be firmly attached to the connection between the electronic connector a1 and the electronic connector b2, thereby maintaining the sealing effect of the connection between the electronic connector a1 and the electronic connector b2. On the one hand, the stability of the connection between the electronic connector a1 and the electronic connector b2 can be protected. On the other hand, the connection between the electronic connector a1 and the electronic connector b2 can be sealed to prevent the external gas from oxidizing or corroding the connection between the electronic connector a1 and the electronic connector b2, as well as the contamination of liquids and even the damage caused by solid collisions, thereby further improving the stability of the connection between the electronic connector a1 and the electronic connector b2;

[0034] During the gradual shrinkage of the airbag 41, one end of the airbag 41 can be manually assisted to keep in contact with the electronic connector a1, thereby ensuring that the airbag 41 is stably shrunk and wrapped around the connection between the electronic connector a1 and the electronic connector b2.

[0035] In the process of pulling the clamping plate 44 to a certain position, the clamping plate 44 drives the damping rod 410 to move, and the damping rod 410 drives the magnetic ring 411 to move along the positioning tube 35. After the clamping plate 44 moves to a certain position, the magnetic ring 411 moves to the groove on the positioning tube 35. At this time, the magnetic ring 411 will be magnetically attracted to the positioning rod 36, so one side of the magnetic ring 411 contacts one side of the positioning rod 36; in addition, after pulling the clamping plate 44 to a certain position, the pull ring 45 is pulled. While the pull ring 45 stretches the telescopic spring 46, the pull ring 45 drives the clamping joint 47 to move until the clamping joint 47 is clamped with the clamping hole on the clamping plate 44, thereby connecting the clamping plate 44 and the pull ring 45 and maintaining Stable, the elastic force generated after the telescopic spring 46 is stretched can make the piston rod 49 and the magnetic ring 411 tend to move in the same direction, and under the tendency of moving in the same direction, the tight application effect of the airbag 41 can be maintained, and the connection between the electronic connector a1 and the electronic connector b2 can be pre-tightened through the positioning rod 36. On the one hand, the sealing effect of the airbag 41 can be maintained, and on the other hand, the connection between the electronic connector a1 and the electronic connector b2 can be pre-tightened. Through the cooperation of these two methods, the stability of the connection between the electronic connector a1 and the electronic connector b2 can be further improved on the basis of maintaining the precise connection between the electronic connector a1 and the electronic connector b2.

[0036] Working principle: When the electronic connector a1 and the electronic connector b2 are docked, the slider 37 under the positioning plate a33 is connected to the guide plate 31, so that the positioning plate a33 drives the electronic connector a1 to slide on the guide plate 31, and then pushes the positioning plate a33, so that the positioning plate a33 slides directionally on the guide plate 31 through the slider 37, and at the same time, the electronic connector a1 approaches the electronic connector b2. At the same time, during the sliding process of the positioning plate a33, the positioning plate a33 drives the positioning rod 36 to move, so that the positioning rod 36 rubs into the interior of the positioning tube 35, and then the electronic connector a1 and the electronic connector b2 are accurately aligned and plugged. The positioning plate a33 slides directionally on the guide plate 31, and the positioning rod 36 slides inside the positioning tube 35 to play a limiting role. Under the cooperation with each other, the connection between the electronic connector a1 and the electronic connector b2 can be made more accurate. At the same time, through the scale on the positioning rod 36, the sliding position of the positioning rod 36 on the positioning tube 35 can be intuitively seen.

[0037] After the electronic connector a1 and the electronic connector b2 are precisely connected, the clamping plate 44 can be pulled, and the clamping plate 44 can drive the piston rod 49 to move, so that one end of the piston rod 49 slides inside the piston cylinder 43. During the sliding process of the piston rod 49, the piston rod 49 extracts the gas inside the airbag 41 through the piston cylinder 43. After the gas inside the airbag 41 is extracted, it will gradually shrink. Since the airbag 41 is arranged on the outside of the electronic connector b2, it is just at the connection between the electronic connector a1 and the electronic connector b2. After the electronic connector a1 and the electronic connector b2 are connected and just wrapped by the airbag 41, during the process of the airbag 41 being evacuated, the airbag 41 gradually shrinks and adheres to the connection between the electronic connector a1 and the electronic connector b2. After the clamping plate 44 moves to a certain position, the airbag 41 will be firmly attached to the connection between the electronic connector a1 and the electronic connector b2.

[0038] In the process of pulling the clamping plate 44 to a certain position, the clamping plate 44 drives the damping rod 410 to move, and the damping rod 410 drives the magnetic ring 411 to move along the positioning tube 35. After the clamping plate 44 moves to a certain position, the magnetic ring 411 moves to the groove on the positioning tube 35. At this time, the magnetic ring 411 will be magnetically attracted to the positioning rod 36, so one side of the magnetic ring 411 contacts one side of the positioning rod 36; in addition, after pulling the clamping plate 44 to a certain position, the pull ring 45 is pulled. While the pull ring 45 stretches the telescopic spring 46, the pull ring 45 drives the clamping joint 47 to move until the clamping joint 47 is clamped with the clamping hole on the clamping plate 44, thereby connecting the clamping plate 44 and the pull ring 45 and maintaining Stable, the elastic force generated after the telescopic spring 46 is stretched can make the piston rod 49 and the magnetic ring 411 tend to move in the same direction, and under the tendency of moving in the same direction, the tight application effect of the airbag 41 can be maintained, and the connection between the electronic connector a1 and the electronic connector b2 can be pre-tightened through the positioning rod 36. On the one hand, the sealing effect of the airbag 41 can be maintained, and on the other hand, the connection between the electronic connector a1 and the electronic connector b2 can be pre-tightened. Through the cooperation of these two methods, the stability of the connection between the electronic connector a1 and the electronic connector b2 can be further improved on the basis of maintaining the precise connection between the electronic connector a1 and the electronic connector b2.
