Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and in particular to a gas-liquid sealing test fixture and an electrical connector testing device. Background Technology

[0002] Mounting plates are core components in high-end electrical connectors, enabling high-density electrical connections and reliable airtightness. They are typically designed with densely packed mounting holes. However, thin-walled areas and stress concentration zones between adjacent mounting holes create potential leakage paths. Under harsh conditions such as extreme temperature cycling, mechanical vibration, and long-term pressure loads, microcracks can form and propagate, leading to slow gas-liquid leakage between the mounting holes. Therefore, accurate detection of microleakage in the mounting holes of mounting plates has become a key technology for improving the reliability of high-end electrical connectors.

[0003] Currently, the industry generally uses GJB1217A-2009 and EIA-364-78 standards to test for overall leakage between mounting holes. This involves inserting a test probe into the mounting hole and applying test air pressure, observing the pressure change to determine if a leak exists. However, test probes are mostly customized for individual products, lacking versatility. Furthermore, they require manual hand-holding to fix the electrical connector, which can lead to uneven stress on the mounting plate and generate additional stress, resulting in a non-sealed gap between the test probe and the mounting hole, severely affecting detection accuracy. In other words, differences in operation by different operators will lead to low repeatability and comparability of test results, making it impossible to form standardized data and resulting in poor consistency of sealing performance.

[0027] See Figure 1 The diagram shows a structural schematic of a gas-liquid sealing test fixture according to an embodiment of the present application. The gas-liquid sealing test fixture includes a fixed base 100, a mounting base 200 and an adjustment component 300. The fixed base 100 is provided with a first connecting part 110 and a second connecting part 120.

[0028] Mounting base 200 is movably connected to the first connecting part 110, and mounting base 200 is used to mount test probe 20.

[0029] The adjustment assembly 300 is connected to the second connecting part 120. The adjustment assembly 300 is used to mount the test mounting plate 30 and to adjust the position of the holes of the test mounting plate 30 on the moving path of the test probe 20. Specifically, the adjustment assembly 300 has a six-way adjustment structure in the spatial coordinate axis direction.

[0030] The gas-liquid sealing test fixture 10 described in this embodiment has a mounting base 200 mounted on a fixed base 100 and an adjustment component 300 mounted on the fixed base 100. The test probe 20 is mounted on the mounting base 200, and the test plate 30 is mounted on the adjustment component 300. The position of the test plate 30 is adjusted to correspond to the movement path of the test probe 20. After the mounting base 200 is released, the test probe 20 is accurately inserted into the hole of the test plate 30 by moving the mounting base 200. Then the mounting base 200 is locked to achieve a precise connection between the test probe 20 and the test plate 30, avoiding the generation of excess stress.

[0031] The gas-liquid sealing test fixture 10 described in this application addresses the technical pain points of existing technologies, such as the tendency for manual control of electrical connector fixing and alignment to generate excess stress, and the limited versatility of fixtures and test probes 20. It achieves multi-dimensional technical optimization. Simultaneously, the coordinated operation of the adjustment component 300 and the mounting base 200 is compatible with machining errors in the holes of the mounting plate 30 under test, significantly improving the versatility and testing efficiency of the gas-liquid sealing test fixture 10. It also greatly reduces the design and manufacturing costs of fixtures for different product specifications, offering advantages such as good versatility and a wide range of adaptability.

[0032] In one exemplary embodiment, the adjustment component 300 can be adapted to the test mounting plate 30 with an end face size of 10mm to 50mm, meeting the testing requirements of circular electrical connectors with housing sizes 9 to 25 in the MIL-DTL-38999 and GJB 599 standards, and can cover the testing requirements of other structural electrical connectors and non-standard electrical connectors. The movable mounting base 200 can be adapted to multi-specification test probes 20 with diameters of 0.89mm to 3.40mm, matching the testing requirements of electrical connectors of sizes 22D, 20, 16, 12, and 10 in the above two standards.

[0033] Combination Figure 2 and Figure 3 The diagram shows another structural schematic of the gas-liquid sealing test fixture in one embodiment of the present application. In some embodiments, the mounting base 200 includes a first mounting plate 210 and a first fastener. The first mounting plate 210 is provided with a third connecting hole 211. The first fastener passes through the third connecting hole 211 and is connected to the first connecting part 110.

[0034] In this embodiment, a third connecting hole 211 is provided on the first mounting plate 210, which mates with the first connecting part 110 on the fixed base 100. A first fastener is inserted to achieve a tight connection or a loose connection between the two. By loosening the first fastener, the position of the mounting base 200 relative to the fixed base 100 can be flexibly adjusted, allowing for precise alignment with the mounting plate 30 to be tested, which has different hole layouts. Simultaneously, the detachable connection of the first fastener facilitates the quick disassembly, replacement, and maintenance of the mounting base 200. When it is necessary to adapt to different specifications of test probes 20 or adjust the testing position, the mounting base 200 can be replaced or adjusted individually without modifying the entire fixture, further improving the versatility, flexibility, and ease of maintenance of the testing fixture, and reducing the cost of using and modifying the equipment.

[0035] In one exemplary embodiment, the first fastener is a bolt or screw.

[0036] In an optional embodiment, such as Figures 1 to 4 As shown, the mounting base 200 also includes a second mounting plate 220 and a third fastener. The first mounting plate 210 and the second mounting plate 220 are connected. The second mounting plate 220 is provided with a fourth connecting hole 221 and a mounting hole 222. The test probe 20 passes through the mounting hole 222, and the third fastener passes through the fourth connecting hole 221 and connects to the test probe 20. That is, the test probe 20 is coaxially arranged with the mounting hole 222, and the axial direction of the test probe 20 is set in the Z-axis direction.

[0037] In this embodiment, the mounting base 200, through the second mounting plate 220 and the third fastener, forms a precise mounting and fixing structure for the test probe 20. The mounting holes 222 on the second mounting plate 220 provide a uniform and high-precision mounting reference for the test probe 20, effectively ensuring the coaxiality of the test probe 20 and the hole in the mounting plate 30 under test. This reduces additional stress and non-sealing gaps caused by probe installation deviations from the source, improving the accuracy and reliability of leak detection results. The third fastener passes through the fourth connecting hole 221 and locks the test probe 20, enabling the test probe 20 to be quickly fixed and replaced in a detachable manner. It is compatible with multiple specifications of test probes 20 without requiring a complete replacement of the mounting base 200, matching different testing needs.

[0038] In one exemplary embodiment, the third fastener is a bolt or screw.

[0039] In an optional embodiment, such as Figure 1 and Figure 3 As shown, the first connecting part 110 is provided with an elongated hole, and the extension direction of the elongated hole is perpendicular to the second mounting plate 220.

[0040] In this embodiment, the first connecting part 110 is designed with an elongated hole structure, and the extension direction of the elongated hole is perpendicular to the second mounting plate 220. This allows the mounting base 200 to move linearly in only one direction along the axial direction of the test probe 20 after the first fastener is loosened. Mechanically, this restricts the freedom of movement of the mounting base 200 and the test probe 20, ensuring that the test probe 20 is accurately inserted into the hole of the mounting plate 30 under test. This completely avoids the lateral offset and coaxiality deviation problems that easily occur when manually inserting and removing the test probe 20, ensuring that the test probe 20 can be accurately and stably inserted into the corresponding hole of the mounting plate 30 under test. This effectively eliminates non-sealing gaps and detection errors caused by insertion deviation of the test probe 20, significantly improving the accuracy and reliability of leakage detection results. At the same time, this embodiment simplifies the test probe 20 alignment process, reduces the skill requirements of operators, and improves the consistency and efficiency of the detection operation.

[0041] In one exemplary embodiment, such as Figure 1 and Figure 3 As shown, the first mounting plate 210 and the second mounting plate 220 are vertically connected, so that the test probe 20 mounted on the second mounting plate 220 is parallel to the fixed base in the axial direction, ensuring that the test probe 20 is always smoothly inserted into the hole to be tested along the axial direction.

[0042] In an optional embodiment, such as Figure 1 and Figure 3 As shown, the second connecting portion 120 is provided with a plurality of second connecting holes, which are arranged in an array on the fixing base 100, and the vertical columns of the second connecting holes are arranged along the extension direction of the elongated holes. For example, by providing a plurality of second connecting portions 120, the adjusting component 300 can adjust the direction of the Z-axis in the spatial coordinate system by connecting the second connecting portions 120 at different positions.

[0043] This embodiment, by setting multiple connecting holes arranged in an array on the fixed base 100, with the vertical column of the second connecting holes arranged along the extension direction of the elongated hole, allows for flexible adjustment of the connection position between the adjusting component 300 and the fixed base 100 according to the external dimensions and hole layout of the mounting plate 30 to be tested of different specifications. This further expands the adaptability of the gas-liquid sealing test fixture 10 to mounting plates of various electrical connectors. On the other hand, it ensures that the installation reference of the adjusting component 300 corresponds precisely to the single axial movement direction of the mounting base 200. From the overall structural level, this guarantees the coaxiality reference of the test probe 20 and the corresponding hole of the mounting plate 30 to be tested is unified, effectively avoiding problems such as insertion deviation of the test probe 20 and non-sealing gaps caused by reference misalignment, further improving the accuracy of leakage detection results and the convenience of detection operation.

[0044] In one exemplary embodiment, the second connecting hole is configured as a circular hole, and a plurality of circular holes are arranged in an array structure on the mounting base 100.

[0045] In an optional embodiment, such as Figure 1 and Figure 3 As shown, the adjustment assembly 300 includes a first adjustment member 310, a second adjustment member 320, a second fastener, a fourth fastener, and a fifth fastener. The first adjustment member 310 includes a first connecting plate 311, and the second adjustment member 320 includes a second connecting plate 321. The first connecting plate 311 is provided with a first adjustment hole 3111, and the second connecting plate 321 is provided with a second adjustment hole 3211. The second fastener and the second connecting part 120 include at least two fasteners. At least one second fastener passes through the first adjustment hole 3111 and the second connecting part 120, and at least one second fastener passes through the second adjustment hole 3211 and the second connecting part 120.

[0046] The adjustment assembly 300 of this embodiment adopts a split structure consisting of a first adjustment member 310 and a second adjustment member 320. The first adjustment member 310 is connected to the second connection part 120 through the first adjustment hole 3111 of the first connecting plate 311, and the second adjustment member 320 is connected to the second connection part 120 through the second adjustment hole 3211 of the second connecting plate 321. By adjusting the connection position of the first adjustment member 310 and the second adjustment member 320 on the fixed base 100, and by using the first adjustment hole 3111 and the second adjustment hole 3211, the independent position fine adjustment of the first adjustment member 310 and the second adjustment member 320 can be achieved. This can flexibly adapt to the installation requirements of insulating mounting plates of electrical connectors with different external dimensions and different hole layouts, further expanding the applicability of the gas-liquid sealing test fixture 10.

[0047] In one exemplary embodiment, the second fastener is a bolt or screw, the fourth fastener is a bolt or screw, and the fifth fastener is a bolt or screw.

[0048] In an optional embodiment, such as Figures 2 to 4 As shown, the first adjusting member 310 further includes a third connecting plate 312, which is connected to the first connecting plate 311. The second adjusting member 320 further includes a fourth connecting plate 322, which is connected to the second connecting plate 321. The third connecting plate 312 is provided with a third adjusting hole 3121, and the fourth connecting plate 322 is provided with a fourth adjusting hole 3221. The adjusting assembly 300 further includes a first movable plate 330, a second movable plate 340, a fourth fastener, and a fifth fastener. The first movable plate 330 is provided with a fifth adjusting hole 331, and the second movable plate 340 is provided with a sixth adjusting hole 341. The fourth fastener passes through the third adjusting hole 3121 and the fifth adjusting hole 331, and the fifth fastener passes through the fourth adjusting hole 3221 and the sixth adjusting hole 341.

[0049] Specifically, the mounting plate 30 to be tested is detachably mounted on the fifth adjustment hole 331 of the first movable plate 330 and the sixth adjustment hole 341 of the second movable plate 340.

[0050] This embodiment features a third connecting plate 312 perpendicularly connected to the first connecting plate 311 on the first adjusting member 310, and a fourth connecting plate 322 perpendicularly connected to the second connecting plate 321 on the second adjusting member 320. A first movable plate 330 and a second movable plate 340 connect the third connecting plate 312 and the fourth connecting plate 322. A fourth fastener passes through the third adjusting hole 3121 on the third connecting plate 312 and the fifth adjusting hole 331 on the first movable plate 330. A fifth fastener passes through the fourth adjusting hole 3221 on the fourth connecting plate 322 and the sixth adjusting hole 341 on the second movable plate 340 to achieve a movable connection. This allows for independent and continuous position adjustment of the mounting plate 30 in two orthogonal directions within a plane perpendicular to the axial direction of the test probe 20. It can precisely adapt to the clamping requirements of mounting plates for electrical connectors with different end face sizes and hole layouts, meeting the testing requirements of various electrical connectors. Meanwhile, the independent adjustment design of the first movable plate 330 and the second movable plate 340 can flexibly adjust the clamping distance and clamping position of the mounting plate 30 to be tested, ensuring that the mounting plate 30 to be tested is clamped firmly without shaking. Structurally, it ensures that the coaxiality of the test probe 20 and the hole to be tested is always consistent, effectively avoiding detection errors caused by clamping displacement, and further improving the accuracy and reliability of leakage detection results.

[0051] In one exemplary embodiment, such as Figure 4 As shown, there are two third adjustment holes 3121 and two fourth adjustment holes 3221. The two third adjustment holes 3121 and the two fourth adjustment holes 3221 can improve the connection stability of the first movable plate 330 and the second movable plate 340.

[0052] In one exemplary embodiment, such as Figure 3 and Figure 4 As shown, the first connecting plate 311 and the third connecting plate 312 are vertically connected, and the second connecting plate 321 and the fourth connecting plate 322 are vertically connected, ensuring the orthogonality of the lateral adjustment direction and the longitudinal adjustment direction, so that the adjustment in the two directions is independent and does not interfere with each other, which facilitates precise control of the clamping position of the mounting plate 30 to be tested in the plane.

[0053] In an optional embodiment, such as Figure 3As shown, the first adjustment hole 3111 is configured as a first oblong hole, with its extension direction parallel to the third connecting plate 312. The second adjustment hole 3211 is configured as a second oblong hole, with its extension direction parallel to the fourth connecting plate 322. Exemplarily, the first oblong hole and the second oblong hole can adjust the direction of the adjustment component 300 along the X-axis in the spatial coordinate system.

[0054] In this embodiment, the first adjustment hole 3111 is designed as a first oblong hole parallel to the third connecting plate 312, and the second adjustment hole 3211 is designed as a second oblong hole parallel to the fourth connecting plate 322. After loosening the second fastener, the first adjustment member 310 and the second adjustment member 320 can achieve continuous stepless lateral position adjustment in the X-axis direction. Together with the second connecting parts 120 arranged in an array on the fixed base 100, they form a combined adjustment system, which can accurately match the clamping spacing requirements of the test mounting plate 30 with different end face sizes. This further improves the adjustment accuracy and adaptability, ensuring that the test mounting plate 30 is clamped firmly and that the coaxiality with the test probe 20 remains accurate. The clamping parameters can be quickly adjusted without replacing any parts, simplifying the operation process and effectively improving the efficiency of the testing work and the versatility of the equipment.

[0055] In an optional embodiment, such as Figure 4 As shown, the third adjustment hole 3121 is configured as a third oblong hole, with its extension direction perpendicular to the first connecting plate 311. The fourth adjustment hole 3221 is configured as a fourth oblong hole, with its extension direction perpendicular to the second connecting plate 321. The fifth adjustment hole 331 is configured as a fifth oblong hole, with a fourth fastener passing through both the third and fifth oblong holes. The sixth adjustment hole 341 is configured as a sixth oblong hole, with a fifth fastener passing through both the fourth and sixth oblong holes. Exemplarily, the third, fourth, fifth, and sixth oblong holes can be combined to adjust the direction of the adjustment assembly 300 along the Y-axis in the spatial coordinate system and to meet the clamping requirements of the mounting plate 30 under test.

[0056] In this embodiment, the third adjustment hole 3121, the fourth adjustment hole 3221, the fifth adjustment hole 331, and the sixth adjustment hole 341 are designed as third oblong holes, fourth oblong holes, fifth oblong holes, and sixth oblong holes, respectively. A fourth fastener is inserted through and connected to the third oblong hole and the fifth oblong hole, respectively. This allows for continuous stepless position adjustment of the adjustment component 300 in a plane perpendicular to the axial direction of the test probe 20. Combined with the lateral adjustment function of the first oblong hole and the second oblong hole, this forms a complete three-dimensional adjustment system, thereby enabling… It precisely adapts to the clamping requirements of mounting plates for electrical connectors with different end face sizes and hole layouts. The clamping position and clamping force can be flexibly adjusted to ensure that the mounting plate 30 under test is clamped firmly without deviation. Structurally, it guarantees the coaxiality accuracy of the test probe 20 and the hole under test, effectively avoiding non-sealing gaps and detection errors caused by clamping deviations. This further improves the accuracy and reliability of leakage detection results. The clamping parameters of different product specifications can be quickly switched without changing any clamping parts, which significantly improves the efficiency of testing and the versatility of the equipment, and reduces testing costs.

[0057] On the other hand, embodiments of this application also provide an electrical connector testing device, such as... Figure 1 and Figure 5 As shown, the device includes a test probe 20 and a gas-liquid sealing test fixture 10 as described in any of the above embodiments. The test probe 20 is detachably mounted on the mounting base 200 of the gas-liquid sealing test fixture 10. The gas-liquid sealing test fixture 10 is used to mount the mounting plate 30 to be tested. The test probe 20 is provided with a tapered end 21, which is used to connect to the mounting plate 30 to be tested.

[0058] The electrical connector testing device described in this embodiment comprises a gas-liquid sealing test fixture 10 and a test probe 20. The test probe 20 adopts an adaptive sealing structure with a tapered end 21, which can effectively adapt to the individual differences in size of the holes in the mounting plate 30 under test due to manufacturing errors. This solves the technical problem that traditional fixed-size probes cannot be compatible with hole size fluctuations and are prone to sealing failure, avoiding deviations in test results caused by poor sealing, significantly reducing the test error rate, and further improving the accuracy and reliability of electrical connector leakage detection results. Furthermore, the test probe 20 adopts a detachable installation design, which facilitates quick replacement of the corresponding specification test probe 20 according to different testing needs, further enhancing the overall versatility and flexibility of the electrical connector testing device.

[0059] In an optional embodiment, such as Figure 1 and Figure 5As shown, the electrical connector testing device also includes a leak detection mechanism and a gas source mechanism. The test probe 20 is equipped with a leak detection interface 23 and a gas source interface 24. The leak detection mechanism is connected to the leak detection interface 23, and the gas source mechanism is connected to the gas source interface 24.
