Description

Technical Field

[0001] This invention relates to the field of electronic connector testing technology, and more specifically, to a device for testing the electrical conductivity of a 2M connector after soldering. Background Technology

[0002] 2M coaxial cable connectors are widely used in communication systems. The key process in their manufacturing is to solder the cable center conductor to the center pin of the connector. The quality of the soldering directly affects the signal transmission performance. Common defects include: poor soldering leading to excessive contact resistance, excessive solder, or soldering misalignment leading to a short circuit between the center conductor and the outer shell.

[0003] In existing technologies, 2M coaxial cable connectors typically require manual testing using a multimeter. Operators observe the multimeter readings and make judgments. During this process, operators need to hold the multimeter probes and touch specific parts, which is cumbersome and unsuitable for rapid batch testing. Furthermore, after prolonged testing, operators are prone to misjudgments or omissions due to fatigue or negligence.

[0004] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a 2M joint welding post-weld power-on detection device. This device can automatically detect the joint through a detection mechanism and intuitively display the detection results through audible and visual signals, guiding the operator to classify and place the joints. Furthermore, the detection process is relatively fast and less prone to misjudgment or omission, thus achieving automation and intelligence in the detection process.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a 2M connector welding post-power-on detection device includes a base, a plurality of brackets are fixedly connected to the base, connector tubes are fixedly connected to the plurality of brackets, an indicator is fixedly connected to the base, and wires are respectively provided on two sockets of the indicator. One of the wires is connected to the connector tube, and a detection head is fixedly connected to the other wire. The base is provided with a detection mechanism for automatic detection.

[0007] According to this scheme, the connector can be directly inserted into the connector tube, so that the pin inside the connector tube contacts the center conductor of the connector. Then, the test head can be held and touched to the connector for testing. In this process, it is not necessary to hold the test end to contact the center conductor of the connector, which is difficult to connect. This is more convenient and faster. Moreover, unlike manual operation, it is less likely to make mistakes during testing.

[0008] The present invention is further configured such that: the detection mechanism includes a placement plate slidably connected to the base, two guide frames one fixedly connected to the placement plate, and two guide frames two fixedly connected to the placement plate; the placement plate is provided with a positioning component for positioning the connector and the detection head.

[0009] According to this scheme, the position of the connector can be restricted and the connector can be guided to the position to be tested by the positioning component. Multiple connectors can be pre-installed for sorting and testing, making the testing more convenient and faster.

[0010] The present invention is further configured such that: the positioning component includes an electric push rod fixedly connected to the placement plate, a receiving plate fixedly connected to the telescopic end of the electric push rod, and a fixing frame fixedly connected to the receiving plate; the fixing frame is fixedly connected to the detection head; and the base is provided with a driving component for driving the placement plate to slide.

[0011] According to this solution, the connector can be received and the tested connector can be discharged without manual removal, making the testing more continuous and automatic. In addition, the fixing frame can also position the testing head to prevent the testing head from blocking the sliding of the tested connector.

[0012] The present invention is further configured such that the end of the receiving plate away from the electric push rod is inclined.

[0013] According to this scheme, the tested connector can slide quickly off the placement plate, thereby improving the testing speed.

[0014] The present invention is further configured such that: the driving component includes an electric push rod two fixedly connected to the base and a connecting block fixedly connected to the telescopic end of the electric push rod two, the connecting block being fixedly connected to the placement plate.

[0015] According to this scheme, the placement plate can be moved by the electric push rod 2, which in turn drives the connector to be inserted into the connector tube for testing. After the test is completed, the connector is pulled off the connector tube, making the testing more continuous and automatic.

[0016] The present invention is further configured such that: a limiting plate is slidably connected to the guide frame two near the fixed frame, a positioning block is fixedly connected to the limiting plate, a sliding rod is fixedly connected to the positioning block, the sliding rod is slidably connected to the adjacent guide frame two, a spring is sleeved on the sliding rod between the positioning block and the adjacent guide frame two, a fixing rod is fixedly connected to the fixed frame, and a driving rod is fixedly connected to the fixing rod.

[0017] According to this scheme, when the connector that has completed testing slides down from the receiving plate, the upper connector of the connector can be blocked by a limiting plate to prevent untested connectors from sliding out and causing missed testing.

[0018] In summary, the present invention has the following beneficial effects: during testing, the connector only needs to be placed between guide frame one and guide frame two, and then the 2M connector can be tested by activating electric push rod one and electric push rod two. The test results are displayed intuitively through sound and light signals, guiding the operator to classify and place the connector. Moreover, the testing is relatively fast and less prone to misjudgment or omission, thus realizing the automation and intelligence of the testing process. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] A device for detecting the electrical continuity of a 2M connector after welding, such as Figures 1-4 As shown, the device includes a base 1, several brackets 2 are fixedly connected to the base 1, connector tubes 3 are fixedly connected to the brackets 2, an alarm 5 is fixedly connected to the base 1 (the alarm 5 has a speaker and a threshold comparison unit inside, and green LED beads and red LED beads are provided on the outer shell of the alarm 5), wires 6 are respectively provided on the two sockets of the alarm 5, one wire 6 is connected to the connector tube 3, and a detection head 7 is fixedly connected to the other wire 6. The base 1 is provided with a detection mechanism for automatic detection.

[0023] like Figures 1-4As shown, during testing, several connectors can be arranged in sequence on the testing mechanism, with the bottom connector contacting the testing head 7. The testing mechanism then drives the connectors into the connector tube 3, causing the pin inside the tube 3 to contact the center conductor of the connector for testing. If the center conductor of the connector is well insulated from the outer shell, the loop current is extremely small (<0.5μA), and the threshold comparison unit inside the alarm 5 determines that the current is below the short-circuit threshold (e.g., set to 1mA). The alarm 5 will receive a "qualified" signal, causing the green LED on the alarm 5 to remain constantly lit, and the speaker inside the alarm 5 to go silent. The operator then sees the green light and can place the connector in the qualified area. If the center conductor of the connector is short-circuited from the outer shell, and the loop current is large (>5mA), the threshold comparison unit inside the alarm 5 determines that the current exceeds the threshold, and the alarm 5 will receive a "unqualified" signal, causing the red LED on the alarm 5 to flash rapidly. The speaker inside the alarm 5 will also emit a "beep" alarm sound. The operator hears the red LED flashing rapidly and hears the alarm, and can then place the connector in the unqualified area.

[0024] like Figures 1-4 As shown, the testing mechanism includes a placement plate 8 slidably connected to the base 1, two guide frames 9 fixedly connected to the placement plate 8, and two guide frames 10 fixedly connected to the placement plate 8. The placement plate 8 is provided with a positioning assembly for positioning the connector and the testing head 7. The positioning assembly includes an electric push rod 11 fixedly connected to the placement plate 8, a receiving plate 12 fixedly connected to the telescopic end of the electric push rod 11, and a fixing frame 13 fixedly connected to the receiving plate 12. The fixing frame 13 is fixedly connected to the testing head 7. The base 1 is provided with a driving component for driving the placement plate 8 to slide. The receiving plate 12 is inclined at the end away from the electric push rod 11. The driving component includes an electric push rod 14 fixedly connected to the base 1 and a connecting block 15 fixedly connected to the telescopic end of the electric push rod 14. The connecting block 15 is fixedly connected to the placement plate 8.

[0025] like Figures 1-4As shown, when placing the connector, the connector with its maximum radius is positioned between guide frame 1 (9) and guide frame 2 (10), ensuring that the maximum radius of the connector is in contact with guide frame 1 (9) and guide frame 2 (10). The remaining connectors are then placed in the same manner. The connectors will then slide down due to gravity and contact the receiving plate 12 and the detection head 7. The connector in contact with the receiving plate 12 is now in the detection position. Then, the electric push rod 2 (14) retracts, causing the placement plate 8 to slide on the base 1. Guide frame 1 (9) and guide frame 2 (10) also move accordingly, thus moving the connector and inserting it into the connector tube 3 (guide frame 1 (9) and guide frame 2 (10) restrict the connector tube 3). This causes the pin inside the connector tube 3 to contact the center conductor of the connector, thus initiating the connection process. The head is inspected (inspection time is 1s-1.5s). After the inspection is completed, the electric push rod 2 14 will extend and reset, pulling the inspected connector off the connector tube 3. After the electric push rod 2 14 resets, the electric push rod 11 will retract and drive the receiving plate 12 to move downward. At this time, the connector in contact with the receiving plate 12 will also move downward. When the connector moves downward until it is no longer in contact with the receiving plate 121 and the receiving plate 122, the connector will slide off the receiving plate 12 and fall onto the base 1. After the connector slides down, the electric push rod 11 will extend and reset, driving the receiving plate 12 to reset. At this time, the connector on the upper side of the connector will also slide down to the inspection state due to gravity. Then the connectors on the base 1 can be classified.

[0026] like Figure 1 , Figure 2 , Figure 4 As shown, a limiting plate 16 is slidably connected to the guide frame 10 near the fixed frame 13. A positioning block 17 is fixedly connected to the limiting plate 16. A sliding rod 18 is fixedly connected to the positioning block 17. The sliding rod 18 is slidably connected to the adjacent guide frame 10. A spring 19 is sleeved between the positioning block 17 and the adjacent guide frame 10. A fixing rod 20 is fixedly connected to the fixed frame 13. A drive rod 21 is fixedly connected to the fixing rod 20.

[0027] like Figure 1 , Figure 2 , Figure 4As shown, when the electric push rod 11 retracts, it also synchronously drives the fixed frame 13, fixed rod 20, and drive rod 21 to move downwards. At this time, the inclined surface of the drive rod 21 pushes the limiting plate 16, causing the limiting plate 16 to slide on the guide frame 10 and extend to the underside of the untested connector. At this time, the spring 19 is in a compressed state, and the limiting plate 16 can block the untested connector, preventing the untested connector from sliding out when the completed connector slides off the receiving plate 12, thus avoiding missed detection. When the electric push rod 11 of the test connector is reset, it will also drive the drive rod 21 to move. At this time, the limit plate 16 will slide on the drive rod 21. When the limit plate 16 slides to the inclined surface of the drive rod 21, the spring 19 will reset, so that the limit plate 16 always fits against the inclined surface of the drive rod 21. At this time, the limit plate 16 will also slide on the guide frame 10 and no longer block the untested connector from sliding down. At this time, the untested connector will slide down to the test position due to gravity, and the untested connector can be tested.

[0028] Working principle: When placing the connector, place the connector at its maximum radius between guide frame 9 and guide frame 10, so that the maximum radius of the connector is in contact with guide frame 9 and guide frame 10. Then place the remaining connectors in the same way. The connector will then slide down due to gravity and come into contact with the receiving plate 12 and the detection head 7. At this time, the connector in contact with the receiving plate 12 is in the position to be tested. Then, the electric push rod 14 will retract and drive the placement plate 8 to slide on the base 1. At this time, guide frame 9 and guide frame 10 will also move, thereby driving the connector to move and insert into the connector tube 3, so that the pin in the connector tube 3 comes into contact with the center conductor of the connector. At this time, the connector will be tested (the test time is 1s-1.5s).

[0029] After the test is completed, the electric push rod 14 will extend and reset, pulling the tested connector off the connector tube 3. When the electric push rod 14 resets, the electric push rod 11 will retract, causing the receiving plate 12 to move downwards. At this time, the connector in contact with the receiving plate 12 will also move downwards. Simultaneously, when the electric push rod 11 retracts, it will also drive the fixing frame 13, fixing rod 20, and drive rod 21 downwards. At this time, the inclined surface of the drive rod 21 will push against the limiting plate 16, causing the limiting plate 16 to slide on the guide frame 10 and extend to the underside of the untested connector, preventing the untested connector from continuing to slide down. Then, the electric push rod continues to retract, and the tested connector will continue to move downwards. When this connector moves downwards until it no longer contacts the receiving plate 12... When receiving plate 121 and receiving plate 122 come into contact, the connector will slide off the receiving plate 12 and fall onto the base 1. After the connector slides off, the electric push rod 11 will extend and reset, causing the receiving plate 12 to reset. When the receiving plate 12 resets, it will also drive the drive rod 21 to move. At this time, the limiting plate 16 will slide on the drive rod 21. When the limiting plate 16 slides to the inclined surface of the drive rod 21, the spring 19 will reset, so that the limiting plate 16 always fits against the inclined surface of the drive rod 21. At this time, the limiting plate 16 will also slide on the guide frame 10 and no longer block the untested connector from sliding down. At this time, the untested connector will slide down to the testing position due to gravity. Then the connectors on the base 1 can be classified.
