Description

Technical Field

[0001] This invention relates to the field of error prevention and verification technology for connector plugs, specifically, to an error prevention and verification device and method for an HVSL connector plug. Background Technology

[0002] HVSL connectors are a type of current connector used in existing charging equipment. They are primarily used in the charging of electric vehicles, allowing current from the charging station to be transmitted to the vehicle. An HVSL connector mainly consists of contacts, a housing, an insulator, and various accessories to facilitate current transmission. Because HVSL connectors can transmit relatively high power, to prevent injury to users, production personnel must select several HVSL connectors from each batch for error-proofing checks before they are put into use. This ensures the normal operation of HVSL connectors during production and use.

[0003] There are currently many error-proofing verification processes for HVSL connectors, including testing the sealing performance, insulation performance, dimensions and appearance, robustness, and durability during long-term use. These tests ensure that the manufactured HVSL connectors can deliver current for extended periods.

[0004] However, in the various testing processes of HVSL connectors, each testing method requires a corresponding testing device. Some of these devices may cause damage to the outer shell and internal components of the HVSL connector during testing methods such as testing the robustness of the HVSL connector shell, the insulation of the HVSL connector shell, and the durability of the HVSL connector shell. Sometimes, the damage to the HVSL connector shell is small and not easily detected by the naked eye of the testing personnel. However, when the damaged HVSL connector shell is tested in other testing equipment, the damage to the HVSL connector shell may cause various accidents during the testing process, which may not only affect the testing effect of the HVSL connector shell, but also damage the testing equipment. Summary of the Invention

[0005] This invention proposes an error-proofing verification device and method for HVSL connectors, which solves the problem in related technologies that, during the process of performing various error-proofing verifications on HVSL connectors, the continued testing of damaged HVSL connectors affects the accuracy of HVSL connector testing and causes damage to various testing equipment.

[0006] The technical solution of the present invention is as follows: A fault-proofing verification device for an HVSL connector includes a detection device, wherein the number of the detection devices is set to multiple, and further includes:

[0007] Rotating support;

[0008] The rotating cylinder is rotatably connected to the rotating support.

[0009] The placement platform is provided in multiple ways, and each placement platform is slidably connected to the inner bottom wall of the rotating cylinder.

[0010] A combined drive assembly is disposed between the rotating cylinder and the plurality of placement platforms, and the combined drive assembly is used to drive the plurality of placement platforms to move.

[0011] A closed detection mechanism is provided on the top of each of the placement platforms. The closed detection mechanism is used to detect external damage to the connector plug.

[0012] A gas injection assembly is disposed between the rotating cylinder and the plurality of closed detection mechanisms, and the gas injection assembly is used to inject detection gas into the closed detection mechanisms.

[0013] A gas discharge assembly is disposed between the rotating cylinder and the plurality of closed detection mechanisms, and the gas discharge assembly is used to discharge the gas detected in the closed detection mechanisms.

[0014] To support the rotating cylinder, preferably, the rotating support includes a rotating ring seat and supporting members, the rotating cylinder is rotatably connected to the rotating ring seat, and multiple supporting members are fixedly connected to the rotating ring seat.

[0015] To ensure stable movement of the placement platform within the rotating cylinder, a sliding frame is further included. The sliding frame is fixedly connected to the inner bottom wall of the rotating cylinder, and the placement platform is slidably connected within the sliding frame.

[0016] To further facilitate the movement of multiple placement platforms within the rotating cylinder, the combined drive assembly includes a rotating disk, internal gear grooves, a first motor, threaded seats, and bent connectors. A rotating ring is fixedly connected to the bottom of the rotating cylinder, and the rotating disk is rotatably connected to the rotating ring. The rotating disk has internal gear grooves with meshing gears engaged thereon. The first motor is mounted on the rotating ring, and the meshing gears are located at the output end of the first motor. A flat threaded section is provided on the top of the rotating disk, and multiple threaded seats are threadedly connected to the flat threaded section. The number of threaded seats is the same as the number of placement platforms. The bent connectors are fixedly connected between the threaded seats on the same side and the placement platforms. Slide grooves are provided on the bottom of the rotating cylinder corresponding to the multiple bent connectors.

[0017] To further test the gas tightness of the connector, the sealing detection mechanism includes a double-headed electric cylinder, a sealing cover, a placement seat, a sealing ring, and a detection component. The double-headed electric cylinder is mounted on the placement platform. Two sealing covers are slidably connected to the top sides of the placement platform. The output end of the double-headed electric cylinder is fixedly connected to the sealing cover. The placement seat is fixedly connected to the middle of the placement platform. The sealing ring is mounted on one of the sealing covers. The detection component is installed inside both sealing covers. The detection component includes a sealing tank and a gas sensor. The sealing tank is fixedly connected inside the sealing cover, and the gas sensor is installed inside the sealing tank.

[0018] In order to inject gas into the sealed enclosure, based on this scheme, the gas injection assembly includes an injection cylinder, an injection pipe, a gas injection sleeve, and a gas injection tube. The injection cylinder is fixedly connected to the rotating cylinder, the injection pipe is connected to the top of the injection cylinder, the top of the injection pipe is rotatably and sealingly connected to the gas injection sleeve, and multiple sealed enclosures close to the injection cylinder are connected to the injection cylinder by the gas injection tube.

[0019] In order to discharge the gas detected in the closed testing mechanism, based on this solution, the gas discharge assembly further includes an exhaust ring sleeve, a sealing ring plate, an exhaust pipe, and a suction pipe. The exhaust ring sleeve is fixedly connected to the support member, the gas filling sleeve is fixedly connected inside the exhaust ring sleeve, the bottom of the exhaust ring sleeve is rotatably connected to the sealing ring plate, and the exhaust pipe is connected between the multiple sealing covers that are far away from the filling cylinder and the sealing ring plate. The suction pipe is connected to the exhaust ring sleeve.

[0020] In order to drive the rotating cylinder to rotate within the rotating ring seat, this solution further includes a fixed seat, a fixed shaft, a transmission gear, and a second motor. The fixed shaft is fixedly connected to the bottom of the rotating cylinder and rotatably connected to the fixed seat. There are two transmission gears that mesh with each other. One of the transmission gears is fixedly sleeved on the fixed shaft. The second motor is mounted on the fixed seat, and the other transmission gear is mounted on the output end of the second motor.

[0021] A method for error-proofing verification of an HVSL connector, using the aforementioned error-proofing verification device for an HVSL connector, includes the following steps:

[0022] Step 1: Remove the placement platform: Start the first motor. Through the meshing relationship between the meshing gear and the internal tooth groove, the rotating disk rotates at the bottom of the rotating cylinder. Through the threaded connection between the flat thread section and the threaded seat, the threaded seat drives the bent connector and the placement platform to move laterally. During the sliding process of the bent connector in the slide groove, the placement platform is removed from the rotating cylinder.

[0023] Step 2: Place the connector plug: Place the connector plug on the placement platform, then start the double-headed electric cylinder to move the two closed covers in opposite directions, so that the near ends of the two closed covers fit together. As the two closed covers close, the two sides of the connector plug placed on the placement seat enter the two closed slots respectively. Then, by driving the rotating disk to rotate, the placement platform is moved back into the rotating cylinder.

[0024] Step 3: Move the rotating cylinder: Start the second motor. Through the meshing effect of the two transmission gears, the fixed shaft and the rotating cylinder will rotate on the rotating ring seat, thereby moving the multiple placement platforms inside the rotating cylinder together and moving the connection plug inside the enclosure to the vicinity of the corresponding testing equipment.

[0025] Step 4: Verify the connector: Gas is injected into the gas filling sleeve, and the gas enters the filling cylinder through the filling pipe. Then, it enters the corresponding sealed hood through the gas filling pipe. The gas sensor in the sealed hood determines the sealing performance of the connector. After the sealing performance of the connector is tested, the placement platform is removed from the rotating cylinder, and the connector is taken out and then further verified by other testing equipment to prevent errors.

[0026] The working principle and beneficial effects of this invention are as follows:

[0027] 1. In this invention, when the connector plug is sequentially subjected to error-proofing verification in multiple testing devices, in order to prevent damage to the connector plug shell after one testing operation, which could lead to complete damage to the connector plug and the testing equipment during the next testing, this application places the connector plug that has completed one testing operation on a placement table. A double-headed electric cylinder drives two sealing covers to move in opposite directions, sealing the connector plug between the two sealing covers. The connector plug is kept sealed by two sealing grooves. Gas is injected into the sealing covers by a gas injection component. Because the connector plug is sealed between the two sealing grooves, the overall sealing of the connector plug may be compromised after the previous testing. Due to the strong flow of gas, if the connector plug is not sealed properly, gas will enter the interior of the connector plug through the gaps. Finally, the gas sensor in the sealing groove detects the gas entering the connector plug, thereby judging the damage of the connector plug and avoiding further testing of the damaged connector plug.

[0028] 2. In this invention, in order to drive the rotating cylinder to rotate within the rotating ring seat through the transmission gear and the fixed shaft, so that the connector can move during the sealing test, and after the sealing test is completed, the connector can be moved to the vicinity of the remaining testing equipment, thereby improving the speed of performing multiple testing operations on the connector.

[0029] 3. In this invention, in order to improve the protection of the testing personnel, when the connector is sealed and placed inside the connector for testing, the rotating disk is driven to rotate, so that the flat thread section drives multiple thread seats and multiple bent connectors to move laterally, thereby controlling the entry and exit of the placement platform in the rotating cylinder, so that the sealing test of the connector is carried out inside the rotating cylinder, and the rotating cylinder provides protection when testing the connector.

[0030] 4. In this invention, after the sealing test of the connector plug is completed, the gas inside the sealed cover is discharged through the exhaust pipe, exhaust ring sleeve and suction pipe, so that the gas inside the sealed cover is discharged as much as possible, which facilitates the recycling of the test gas.

[0031] 5. Therefore, the error-proofing verification device for the HVSL connector can strictly monitor the sealing performance of the connector during multiple error-proofing verifications, avoiding inaccurate testing results and damage to the testing equipment due to connector damage.

[0045] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0046] like Figures 1 to 10 As shown, this embodiment proposes an error-proofing verification device for HVSL connectors, including a detection device 1. The number of detection devices 1 is set to multiple. The multiple detection devices 1 are existing verification devices used to perform various error-proofing verification operations on the connectors. Each detection device 1 performs different verification operations on the connectors. The detection devices 1 are existing devices known to those skilled in the art, and will not be described in detail here.

[0047] It also includes a rotating support 100, a rotating cylinder 2, and a placement platform 3. The rotating cylinder 2 is rotatably connected to the rotating support 100. The rotating support 100 includes a rotating ring seat 4 and support members 5. The rotating cylinder 2 is rotatably connected to the rotating ring seat 4, and multiple support members 5 are fixedly connected to the rotating ring seat 4. It also includes a fixed base 27, a fixed shaft 28, transmission gears 29, and a second motor 30. The fixed shaft 28 is fixedly connected to the bottom of the rotating cylinder 2 and rotatably connected to the fixed base 27. The number of transmission gears 29 is set to two. Two transmission gears 29 mesh, one of which is fixedly mounted on the fixed shaft 28. The second motor 30 is mounted on the fixed seat 27, and the other transmission gear 29 is mounted on the output end of the second motor 30. When it is necessary to drive the rotating cylinder 2 and the components mounted on the rotating cylinder 2 to rotate on the rotating ring seat 4, the second motor 30 is started. Through the meshing effect of the two transmission gears 29, the fixed shaft 28 and the rotating cylinder 2 are driven to rotate on the rotating ring seat 4, thereby causing the multiple placement platforms 3 inside the rotating cylinder 2 to move together.

[0048] The number of placement platforms 3 is set to multiple, and each placement platform 3 is slidably connected to the inner bottom wall of the rotating cylinder 2. It also includes a sliding frame 6, which is fixedly connected to the inner bottom wall of the rotating cylinder 2. The placement platform 3 is slidably connected within the sliding frame 6. A combined drive assembly 200 is disposed between the rotating cylinder 2 and the multiple placement platforms 3. The combined drive assembly 200 is used to drive the multiple placement platforms 3 to move. The combined drive assembly 200 includes a rotating disk 7, an internal gear groove 8, a first motor 10, threaded seats 11, and a bent connecting piece 12. A rotating ring 31 is fixedly connected to the bottom of the rotating cylinder 2. The rotating disk 7 is rotatably connected to the rotating ring 31. The rotating disk 7 is provided with an internal gear groove 8, and a meshing gear 9 meshes on the internal gear groove 8. The first motor 10 is disposed on the rotating ring 31, and the meshing gear 9 is disposed on the output end of the first motor 10. A flat threaded section is provided on the top of the rotating disk 7, and multiple threaded seats 11 are threadedly connected to the flat threaded section. The number of threaded seats 11 is the same as the number of placement platforms 3. A bent connector 12 is fixedly connected between the threaded seat 11 on the same side and the placement platform 3. The bottom of the rotating cylinder 2 has a sliding groove corresponding to multiple bent connectors 12. When it is necessary to control the entry and exit of the placement platform 3 in the rotating cylinder 2, multiple inlets and outlets are opened on the rotating cylinder 2 corresponding to the placement platform 3. Each inlet and outlet is provided with a cover 32, which is fixedly connected to the placement platform 3. By starting the first motor 10, the rotating disk 7 is driven to rotate at the bottom of the rotating cylinder 2 through the meshing relationship between the meshing gear 9 and the internal tooth groove 8. Through the threaded connection between the flat thread section and the threaded seat 11, and under the restriction effect of the sliding groove and the sliding frame 6, the threaded seat 11 will not rotate with the rotating disk 7. The threaded seat 11 drives the bent connector 12 and the placement platform 3 to move laterally. Due to the special shape of the bent connector 12, the placement platform 3 is moved out of the rotating cylinder 2 during the sliding process of the bent connector 12 in the sliding groove, which makes it convenient for the inspection personnel to take out or put in the connector plug.

[0049] Each placement platform 3 is equipped with a sealing detection mechanism 300 on its top. The sealing detection mechanism 300 is used to detect external damage to the connector plug. The sealing detection mechanism 300 includes a double-headed electric cylinder 13, a sealing cover 14, a placement seat 15, a sealing ring 16, and a detection component. The placement platform 3 is equipped with a double-headed electric cylinder 13, and there are two sealing covers 14. The two sealing covers 14 are slidably connected to the top two sides of the placement platform 3, respectively. The output end of the double-headed electric cylinder 13 is fixedly connected to the sealing cover 14. The placement seat 15 is fixedly connected to the middle of the placement platform 3, and the sealing ring 16 is... 6 is installed on one of the closed covers 14. Both closed covers 14 contain detection components, each including a sealed tank 17 and a gas sensor 18. The sealed tank 17 is fixedly connected inside the closed cover 14, and the gas sensor 18 is installed inside the sealed tank 17. To achieve the purpose of sealing performance testing during the movement of the connector, after the placement platform 3 is removed from the rotating cylinder 2, the connector is placed on the placement platform 3. Then, the double-headed electric cylinder 13 is activated to move the two closed covers 14 in opposite directions, causing the adjacent ends of the two closed covers 14 to fit together. To ensure a tight seal with the placement base 15, both sealed covers 14 have grooves at their bottom ends near the placement base 15. These grooves fit snugly against the corresponding areas of the placement base 15. The sealing ring 16 seals the fitted ends of the two sealed covers 14, preventing gas leakage. As the two sealed covers 14 close, the two sides of the connector placed on the placement base 15 enter the two sealed grooves 17. The inner wall shape of the sealed groove 17 corresponds to the shape of the connector, ensuring a tight seal. The connector is fitted to the housing of the connector. When the test gas is released into the sealed enclosure 14, if the connector is damaged during the previous test, the connector will have poor sealing. At this time, the air added into the sealed enclosure 14 will enter the connector. The gas sensor 18 in the sealed tank 17 is an existing device for precise gas monitoring. The gas sensor 18 can detect the entry of external air into the connector, thereby judging the sealing of the connector and avoiding the continued use of the damaged connector.

[0050] A gas filling assembly 400 is disposed inside the rotating cylinder 2 and between multiple closed detection mechanisms 300. The gas filling assembly 400 is used to fill the closed detection mechanisms 300 with detection gas. The gas filling assembly 400 includes a filling cylinder 19, a filling pipe 20, a gas filling sleeve 21, and a gas filling tube 22. The filling cylinder 19 is fixedly connected inside the rotating cylinder 2. The filling pipe 20 is connected to the top of the filling cylinder 19. The top of the filling pipe 20 is rotatably and sealingly connected to the gas filling sleeve 21. Multiple closed covers 14 close to the filling cylinder 19 are all connected to the filling cylinder 19 by gas filling tubes 22. In order to fill the closed covers 14 with gas, gas is filled into the gas filling sleeve 21. The gas is fed into the filling sleeve 21, through the filling pipe 20, into the filling cylinder 19, and then through the filling pipe 22 into the corresponding sealed cover 14. Since not all the placement platforms 3 need to be used at the same time, each filling pipe 22 is equipped with a control valve. The control valve controls the opening and closing of some filling pipes 22 to allow the gas to enter the sealed cover 14. In order to facilitate the filling of gas into the filling pipe 20 and not affect the normal rotation of the filling pipe 20 and the filling cylinder 19, the gas first enters the filling sleeve 21. During the rotation of the filling pipe 20, the gas added to the filling sleeve 21 does not affect the gas added to the filling pipe 20 entering the filling pipe 20.

[0051] A gas discharge assembly 500 is disposed between the rotating cylinder 2 and multiple closed detection mechanisms 300. The gas discharge assembly 500 is used to discharge the gas detected within the closed detection mechanisms 300. The gas discharge assembly 500 includes an exhaust ring sleeve 23, a closed ring plate 24, an exhaust pipe 25, and a suction pipe 26. The exhaust ring sleeve 23 is fixedly connected to the support member 5, and the gas filling sleeve 21 is fixedly connected inside the exhaust ring sleeve 23. The bottom of the exhaust ring sleeve 23 is rotatably connected to the closed ring plate 24. Multiple closed covers 14 located further away from the filling cylinder 19 are connected to the closed ring plate 24 by exhaust pipes 25. The gas ring sleeve 23 is connected to an exhaust pipe 26. After the sealing plug inside the enclosure 14 is tested for sealing, the gas inside the enclosure 14 is extracted through the exhaust pipe 26 using an external device. The air inside the enclosure 14 enters the exhaust ring sleeve 23 through the exhaust pipe 25 and is then discharged through the exhaust pipe 26. This facilitates the recovery and reuse of the test gas. In order not to affect the movement of the exhaust pipe 25 with the enclosure 14, a sealing ring plate 24 is rotatably connected to the bottom of the exhaust ring sleeve 23, so that the sealing ring plate 24 and the exhaust pipe 25 rotate at the bottom of the exhaust ring sleeve 23.

[0052] A method for error-proofing verification of an HVSL connector, using the aforementioned error-proofing verification device for an HVSL connector, includes the following steps:

[0053] Step 1, Remove the placement platform 3: Start the first motor 10. Through the meshing relationship between the meshing gear 9 and the internal tooth groove 8, drive the rotating disk 7 to rotate at the bottom of the rotating cylinder 2. Through the threaded connection between the flat thread section and the threaded seat 11, the threaded seat 11 drives the bent connecting piece 12 and the placement platform 3 to move laterally. During the sliding process of the bent connecting piece 12 in the slide groove, the placement platform 3 is removed from the rotating cylinder 2.

[0054] Step 2: Place the connector plug: Place the connector plug on the placement platform 3, and then start the double-headed electric cylinder 13 to drive the two closed covers 14 to move in opposite directions, so that the near ends of the two closed covers 14 are in contact. As the two closed covers 14 close, the two sides of the connector plug placed on the placement seat 15 enter the two closed grooves 17 respectively. Then, by driving the rotating disk 7 to rotate, the placement platform 3 is moved back into the rotating cylinder 2.

[0055] Step 3, Moving the rotating cylinder 2: Start the second motor 30. Through the meshing effect of the two transmission gears 29, drive the fixed shaft 28 and the rotating cylinder 2 to rotate on the rotating ring seat 4, so that the multiple placement platforms 3 inside the rotating cylinder 2 move together, and move the connecting plug inside the enclosure 14 to the vicinity of the corresponding testing device 1.

[0056] Step 4: Verify the connector: Gas is injected into the gas filling sleeve 21, and the gas enters the filling cylinder 19 through the filling pipe 20, and then enters the corresponding sealing cover 14 through the gas filling pipe 22. The gas sensor in the sealing tank 17 determines the sealing performance of the connector. After the sealing performance of the connector is tested, the placement platform 3 is removed from the rotating cylinder 2, and the connector is taken out and continued to be checked by other testing equipment 1 to prevent errors.

[0057] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

10. A method for error-proofing verification of an HVSL connector, using the error-proofing verification device for an HVSL connector as described in claim 9, characterized in that, Includes the following steps: S1. Remove the placement platform (3): Start the first motor (10), and through the meshing relationship between the meshing gear (9) and the internal tooth groove (8), drive the rotating disk (7) to rotate at the bottom of the rotating cylinder (2). Through the threaded connection between the flat thread section and the threaded seat (11), the threaded seat (11) drives the bent connecting piece (12) and the placement platform (3) to move laterally. During the sliding process of the bent connecting piece (12) in the groove, the placement platform (3) is removed from the rotating cylinder (2). S2, Place the connector: Place the connector on the placement platform (3), then start the double-headed electric cylinder (13) to drive the two closed covers (14) to move in opposite directions, so that the two closed covers (14) are close together. As the two closed covers (14) close together, the two sides of the connector placed on the placement seat (15) enter the two closed slots (17) respectively. Then, by driving the rotating disk (7) to rotate, the placement platform (3) is moved back into the rotating cylinder (2). S3. Move the rotating cylinder (2): Start the second motor (30), and through the meshing effect of the two transmission gears (29), drive the fixed shaft (28) and the rotating cylinder (2) to rotate on the rotating ring seat (4), so that the multiple placement platforms (3) inside the rotating cylinder (2) move together, and move the connecting plug inside the enclosure (14) to the vicinity of the corresponding testing equipment (1); S4. Verify the connector: By adding gas into the gas filling sleeve (21), the gas enters the filling cylinder (19) through the filling pipe (20) in the gas filling sleeve (21), and then enters the corresponding sealed cover (14) through the gas filling pipe (22). The gas sensor in the sealed tank (17) determines the sealing performance of the connector. After the sealing performance of the connector is tested, the placement platform (3) is removed from the rotating cylinder (2), and the connector is taken out and then the error prevention verification operation is carried out through other testing equipment (1).
