[0002] An airtight detection device is a device used to test the airtightness of an object or system, and evaluates its sealing performance by detecting whether there is gas leakage. Wires are widely used in various electronic and electrical equipment, and their airtightness is directly related to the stability and safety of the equipment. If there is a gas leakage problem in the wire, it may cause the internal components of the equipment to be affected by moisture, oxidized, or even short-circuited, thus affecting the normal operation of the equipment and directly related to the performance and use safety of the equipment. Therefore, the airtight detection of wires is not only a necessary link for quality control but also a key step to ensure the safety and reliability of products.
[0003] Existing methods for airtight testing of wires often damage the body of the sample wire. Traditional methods include immersing the wire in water for bubble detection.

[0022] As Figure 1 and Figure 2 As shown, a waterproof airtight test jig includes an outer shell 1, and a through hole 2 penetrating itself is provided at one end of the outer shell 1. A wire 4 placed inside a seal 3 is connected inside the through hole 2 through the seal 3. An air valve pipe 5 penetrating itself is provided on one side of the outer shell 1, and a pressure detection plate 6 placed inside the outer shell 1 is provided at one end of the air valve pipe 5 close to the outer shell 1. A digital display screen 7 electrically connected to the pressure detection plate 6 is provided on one side of the outer shell 1. The outer shell 1 includes a bottom shell 7 penetrated by the air valve pipe 5 and a top cover 8 located above the bottom shell 7. The bottom shell 7 and the cover 8 are connected by a rotating shaft hinge 9. Sealing rings 10 placed inside themselves are provided on one side of the bottom shell 7 and the cover 8 close to each other. An airtight groove 11 is provided inside the sealing ring 10, and the pressure test plate 6 is placed in the airtight groove 11 on the bottom shell 7.
[0023] In this implementation, by providing a seal 3 sleeved outside the wire 4 and penetrating the outer shell 1, the sealing performance between the wire 4 and the outer shell 1 is ensured. The wire 4 passes through the seal 3 and is inserted into the outer shell 1. Gas is continuously supplied into the outer shell 1 through the air valve pipe 5. When the internal pressure reaches a certain value, the gas supply is stopped, and it is observed whether the internal pressure of the outer shell 1 decreases, so as to judge whether the airtightness of the wire is good.
[0024] As Figure 2 and Figure 3 As shown, the seal 3 includes a rubber plug 12 corresponding to the through hole 2 on the bottom shell 7, and a seal auxiliary 13 corresponding to itself is provided at one end of the rubber plug 12 away from the airtight groove 11. The through hole 2 on the top cover 8 is smaller than the through hole 2 on the bottom shell 7 and has a different shape. The seal auxiliary 13 and the rubber plug 12 are detachable structures, which are convenient for quick replacement and adjustment between wires of different specifications, thereby improving the adaptability and use efficiency of the test device. The top cover 8 and the bottom shell 7 are connected by a quick lock structure, and the air valve pipe 5 is equipped with an automatic air valve control system, which can automatically adjust the input and output of gas according to the detection requirements, realizing a fully automated airtight detection process.

[0026] When in use:
[0027] 1. Install the wire material: First, insert the wire material 4 to be tested into the outer shell 1 through the through hole 2, and ensure that the wire material 4 passes through the seal 3. Adjust the seal 3 to tightly wrap the wire material 4 to ensure the sealing between the wire material and the outer shell 1.
[0028] 2. Sealing device: Check whether the rubber plug 12 and the sealing auxiliary 13 are correctly installed at the through hole 2, ensure that the seal 3 is aligned with the through hole 2 on the bottom shell 7, and the shape of the through hole 2 on the top cover 8 is the same as that of the through hole 2 on the bottom shell 7.
[0029] 3. Connect the power supply: Connect the electrical connection between the digital display screen 7 and the pressure detection board 6, and ensure that the digital display screen 7 works properly to monitor and display the pressure data inside the outer shell 1 in real time.
[0030] 4. Gas input: Convey gas into the outer shell 1 through the air valve pipeline 5. The air valve pipeline 5 is equipped with an automatic air valve control system to automatically adjust the input amount of gas according to the detection requirements. Observe the pressure inside the outer shell 1 gradually increasing, and stop conveying gas when the set value is reached.
[0031] 5. Pressure monitoring: The pressure detection board 6 detects the pressure change inside the outer shell 1 in real time and transmits the data to the digital display screen 7 for display. Keep it for a period of time and observe whether the internal pressure remains stable.
[0032] 6. Airtightness judgment: If the pressure inside the outer shell 1 does not drop significantly within the set time, it means that the airtightness of the wire material 4 is good. If the pressure drops significantly, it indicates that there is an airtightness problem with the wire material 4.
[0033] 7. Remove the wire material: After the test is completed, open the top cover 8 through the quick locking structure and take out the wire material 4 from the outer shell 1. The sealing auxiliary 13 and the rubber plug 12 are detachable structures, which are convenient for quickly replacing wire materials of different specifications for the next test.
[0034] 8. Data processing: Through the data storage and transmission functions on the digital display screen 7, export the test data to a computer or other data terminals for further data analysis and quality control.
[0035] The above steps ensure good sealing between the wire 4 and the outer housing 1 during the airtight test. By using an automatic air valve control system and a high-precision pressure detection system, an efficient and accurate airtight detection process is achieved.
