[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] This utility model provides, for example Figures 1-5 The device shown is an electrical connector airtightness testing device, comprising:

[0046] Base 100;

[0047] The guide rail 200 is fixed to the top of the base 100, and a triangular protrusion 210 is provided in the middle of the guide rail 200.

[0048] The sliding frame 300 slides along the guide rail 200 and is equipped with a first clamping component 400 and a second clamping component 500. The sliding frame 300 provides space for the placement of the electrical connector and drives the electrical connector to slide to the designated position.

[0049] A bracket assembly 600 is fixedly installed on the top of the base 100, and a detection seat 700 is fixedly installed on the bracket assembly 600.

[0050] The process involves activating a hydraulic cylinder connected to the sliding frame 300 or manually pushing the sliding frame 300 to slide along the guide rail 200 and move it below the detection seat 700. This causes the triangular protrusion 210 to push the first clamping assembly 400 and the second clamping assembly 500 to slide and clamp the electrical connector. Then, the structure in the bracket assembly 600 is activated to lower the detection seat 700 and engage it on the sliding frame 300. Gas is then introduced to test the airtightness of the electrical connector.

[0051] In some embodiments of this utility model, guide grooves 310 are provided at both ends of the sliding frame 300. The guide grooves 310 provide space for the installation of the first clamping component 400 and guide the sliding of the first clamping component 400.

[0052] In some embodiments of this utility model, the first clamping assembly 400 includes:

[0053] The first clamping plate 410 clamps the goods by axial sliding with the push of the triangular protrusion 210 when the sliding frame 300 slides. The triangular protrusion 210 pushes the first clamping plate 410 to clamp and fix the goods when the first clamping assembly 400 slides, so that the electrical connector remains stable when the air tightness is tested, and the air tightness is not shifted. When the air tightness is not tested, the clamping of the electrical connector is released, which facilitates the removal and placement of the electrical connector.

[0054] The sliding column 420 is slidably installed inside the guide groove 310 and drives the first clamping plate 410 to slide under the pressure of the triangular protrusion 210. The sliding column 420 plays a guiding role in the sliding of the first clamping plate 410.

[0055] The baffle plate 430 is fixed to the outside of the sliding column 420 and slides along the guide groove 310;

[0056] Compression spring 440, the two ends of compression spring 440 are fixedly connected to the inner wall of blocking plate 430 and guide groove 310 respectively, and compress and store force when blocking plate 430 slides. When compression spring 440 is set to be misaligned with triangular protrusion 210, it drives the first clamping plate 410 to reset and release the clamping and fixing of the electrical connector.

[0057] Two symmetrically arranged first trapezoidal blocks 450 are installed on the first clamping plate 410.

[0058] When the sliding post 420 contacts the triangular protrusion 210, the inclined surface of the triangular protrusion 210 causes the first clamping plate 410 and the blocking plate 430 to slide, so that the first clamping plate 410 clamps the electrical connector. When the blocking plate 430 squeezes the compression spring 440, the compression spring 440 is compressed and stores force. After the sliding post 420 and the triangular protrusion 210 are misaligned, the elastic force of the compression spring 440 is released, so that the compression spring 440 pushes the first clamping plate 410 and the blocking plate 430 to reset.

[0059] In some embodiments of this utility model, the second clamping assembly 500 further includes:

[0060] The second clamping plate 510 is disposed inside the sliding frame 300, and the electrical connector is clamped and fixed by the second clamping plate 510.

[0061] The tension spring 520 has two ends that are fixedly connected to the inner wall of the sliding frame 300 and the second clamping plate 510, respectively. The tension spring 520 causes the second clamping plate 510 to reset and release the clamping of the electrical connector after the extrusion pressure of the second clamping plate 510 is removed.

[0062] The second trapezoidal block 530 is installed on the second clamping plate 510. Two symmetrically arranged second trapezoidal blocks 530 are installed on the second clamping plate 510. When the first trapezoidal block 450 and the second trapezoidal block 530 are squeezed, they push the second clamping plate 510 to slide. Through the cooperation of the first trapezoidal block 450 and the second trapezoidal block 530, the first clamping plate 410 can push the second clamping plate 510 to slide synchronously when sliding, thereby improving the clamping effect of the electrical connector.

[0063] When the first clamping plate 410 slides, the first trapezoidal block 450 will press against the second trapezoidal block 530, causing the second trapezoidal block 530 to move and clamp the electrical connector, and stretch the tension spring 520. When the first trapezoidal block 450 and the second trapezoidal block 530 are released from compression, the tension spring 520 will drive the first clamping plate 410 to reset and release the clamping.

[0064] In some embodiments of this utility model, the support assembly 600 includes:

[0065] Four support columns 610 are provided and fixed to the top of the base 100 in a rectangular array.

[0066] Top plate 620, top plate 620 is fixed to the top of support column 610;

[0067] Telescopic rod 630 is fixed on top plate 620 and drives test seat 700 to engage with sliding frame 300. The telescopic rod 630 extends and retracts to drive test seat 700 to rise and fall, thereby performing airtightness test on electrical connector.

[0068] In use, the telescopic rod 630 is activated, causing the telescopic rod 630 to lower the test seat 700 and engage it with the sliding frame 300 to test the airtightness. After the test is completed, the telescopic rod 630 is activated again, causing the telescopic rod 630 to raise the test seat 700.

[0069] The working method of this utility model:

[0070] The hydraulic cylinder connected to the sliding frame 300 is activated or the sliding frame 300 is pushed manually, causing the sliding frame 300 to slide along the guide rail 200 and move to the bottom of the test seat 700. The triangular protrusion 210 pushes the first clamping plate 410 and the blocking plate 430 to slide, causing the first clamping plate 410 to clamp the electrical connector. The blocking plate 430 compresses the compression spring 440, causing the compression spring 440 to compress and store force. The telescopic rod 630 is activated, causing the telescopic rod 630 to drive the test seat 700 to descend and engage with the sliding frame 300 to test the airtightness.

[0071] After the test is completed, the telescopic rod 630 is activated again, causing the telescopic rod 630 to lift the test seat 700 and push the sliding frame 300 to reset, so that the sliding column 420 and the triangular protrusion 210 begin to be misaligned. When the sliding column 420 and the triangular protrusion 210 are misaligned, the elastic force of the compression spring 440 is released, so that the compression spring 440 pushes the first clamping plate 410 and the blocking plate 430 to reset.

[0072] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
