Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, specifically to a device for testing the pull-out force of aviation connector components. Background Technology
[0002] In aircraft electrical systems, aviation connectors primarily connect critical equipment such as flight control systems, instrument systems, and communication systems, ensuring the stability of power and data transmission. As a key component of aviation connectors, their electrical parameters directly affect circuit reliability.
[0003] like Figure 1 As shown, the contact body consists of a pin 1 and a socket 2 to which it is inserted. It is a key core component of the aviation connector assembly. As a functional component for current or signal transmission, the contact body must have an excellent structure, stable and reliable contact holding force, and good conductivity.
[0004] The aviation connector assembly is used to connect the pins 1 and sockets 2 of the contact body respectively, and then fix the contact body by mating. The aviation connector assembly has two mating bodies 3, and multiple connection holes 31 are opened inside the mating bodies 3. The buckles 32 are inserted into the connection holes 31. The buckles 32 are cylindrical opening structures. The pins 1 and sockets 2 are inserted into the buckles 32 by interference fit, so that the pins 1 and sockets 2 cannot slip out. The buckles 32 fix the contact body and bear the axial insertion and extraction force transmitted by the pins 1 and sockets 2. Therefore, as a key component of the aviation connector assembly, the buckles 32 need to ensure that the buckles 32 have a certain pull-out resistance when inserted into the connection holes 31. However, at present, the pull-out resistance of the aviation connector assembly is generally tested by manual operation, which is labor-intensive and inefficient. Utility Model Content

[0021] The technical solution adopted by this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments.
[0022] This utility model provides a device for detecting the pull-out resistance of aircraft connector components, used to detect the pull-out resistance of the buckle 32 inserted into the connection hole 31 on the connector body 3 of the aircraft connector component. Figure 2-3 As shown, it includes:
[0023] Mounting bracket 4 serves as the foundation of the entire testing device and supports the entire testing device. In this embodiment, mounting bracket 4 consists of mounting base plate 41 and vertical plate 42 fixedly connected to mounting base plate 41 and vertically arranged. Mounting base plate 41 is used to fix the entire testing device on the ground, and vertical plate 42 is used to provide longitudinal movement space for the testing device. Ribs 43 can also be fixedly connected between mounting base plate 41 and vertical plate 42 to increase the overall stability of mounting bracket 4.
[0024] The first slide cylinder 5 adopts existing technology, such as... Figure 4 As shown, it includes a cylinder and an air inlet 51 and an exhaust port 52 disposed on one side of the cylinder. By introducing gas into the air inlet 51 and the exhaust port 52 respectively, the piston shaft 53 inside the cylinder can be controlled to extend and retract, and the first slide 54 fixedly connected to the end of the piston shaft 53 can be driven to move together with the piston shaft 53. The first slide 54 is provided with bolt holes 55 for fixed connection with other components.
[0025] In this embodiment, the first slide cylinder 5 is fixedly mounted on the vertical plate 42 of the mounting bracket 4, and the movement direction of the first slide 54 is longitudinal.
[0026] The detection mounting plate 6 is fixedly connected to the first slide 54 of the first slide cylinder 5;
[0027] The linear guide rail 8 is fixedly connected to the detection mounting plate 6. The axis of the linear guide rail 8 is set along the longitudinal direction. The slider 81 is slidably set on the linear guide rail 8 so that the sliding direction of the slider 81 is parallel to the moving direction of the first slide table 54. The two ends of the linear guide rail 8 are also provided with blocking blocks to prevent the slider 81 from sliding out of the linear guide rail 8.
[0028] The sensor mounting base 82 is fixedly connected to the slider 81, such as... Figure 5 As shown, the sensor mounting base 82 consists of a base plate 821 and support plates 822 fixedly disposed at both ends of the base plate 821, so that the sensor mounting base 82 is U-shaped. The base plate 821 is fixedly connected to the slider 81, and the two support plates 822 are respectively located on the upper and lower sides of the base plate 821.
[0029] The detection rod 84 is fixedly connected to one end of the support plate 822 above the sensor mounting base 82 via the tension sensor 83. The other end of the detection rod 84 is fitted with a sleeve 11. The end of the detection rod 84 passing through the sleeve 11 is fixedly connected to multiple elastic clips 841 arranged in an array around the axis of the detection rod 84.
[0030] In this embodiment, the number of elastic clips 841 is preferably four.
[0031] like Figure 7As shown, the end of the elastic clip 841 away from the sleeve 11 is inclined to the outside of the detection rod 84. That is, the shape formed by the multiple elastic clips 841 in the normal state is similar to a truncated cone. The multiple elastic clips 841 can shrink radially along the detection rod 84. The shape and size of the multiple elastic clips 841 that are shrunk together are the same as the shape and size of the detection rod 84. The multiple elastic clips 841 can be shrunk together by sliding the sleeve 11 on the detection rod 84. Each elastic clip 841 is provided with a groove 842. When the multiple elastic clips 841 shrink radially together, the multiple grooves 842 form a retaining ring. The diameter of the retaining ring is larger than the inner diameter of the sleeve 11 and smaller than the inner diameter of the buckle 32.
[0032] The ends of multiple elastic clips 841 away from the sleeve 11 are inserted into the inner wall of the buckle 32, that is, the ends of multiple elastic clips 841 can be inserted into the buckle 32 and contract under the action of the inner wall of the buckle 32.
[0033] The control mechanism, which is fixedly mounted on the detection mounting plate 6, includes:
[0034] The second slide cylinder 7 has the same structure as the first slide cylinder 5. It is fixedly mounted on the detection mounting plate 6 and located above the linear guide rail 8. The second slide of the second slide cylinder 7 can move longitudinally, that is, the movement directions of the first slide 54 and the second slide are parallel, both moving longitudinally.
[0035] The second slide of the second slide cylinder 7 is fixedly connected to the sleeve connecting plate 71. The two sides of the bottom end of the sleeve connecting plate 71 are respectively fixedly connected to the sleeve connecting rod 72. The sleeve connecting rod 72 can slide through the spring seat 9, and the end of the sleeve connecting rod 72 that passes through the spring seat 9 is fixedly connected to the sleeve mounting seat 10. The top surface of the sleeve mounting seat 10 is preferably inserted into the bottom surface of the spring seat 9. The sleeve 11 is fixedly connected to the bottom surface of the sleeve mounting seat 10.
[0036] Spring seat 9 is fixedly mounted on the detection mounting plate 6 and located below the linear guide rail 8, such as... Figure 6 As shown, a through groove 91 is opened in the spring seat 9, and the support plate 822 located below the sensor mounting base 82 is inserted into the through groove 91 and is elastically connected to the inner wall of the bottom of the through groove 91 by the spring 92.
[0037] The detection rod 84 can be moved through the support plate 822, spring 92, and sleeve mounting base 10 located below the sensor mounting base 82 in sequence.
[0038] In practical use, this invention first uses a special clamp to clamp the docking body 3. Then, a moving device is used to move the special clamp below the detection rod 84, aligning the inner diameter of the buckle 32 in the connecting hole 31 with the detection rod 84. Then, the first slide 54 of the first slide cylinder 5 is activated and moves downwards, causing multiple elastic clamping petals 841 to move downwards. As the ends of the multiple elastic clamping petals 841 contact the inner wall of the buckle 32, they contract until the ends of the elastic clamping petals 841 pass through the bottom end of the buckle 32. At this point, the ends of the multiple elastic clamping petals 841 are no longer under pressure and disperse under their own elasticity. The slots 842 on the elastic clamping petals 841 engage with the outer edge of the bottom end of the buckle 32, thus achieving the engagement of the buckle. The buckle 32 is engaged, and then the first slide 54 of the first slide cylinder 5 is activated to move upward, that is, to apply a pull-out force to the buckle 32. During the process, the tension on the detection rod 84 is used on the tension sensor 83. By continuously controlling the first slide 54 to move upward, the pull-out force of the buckle 32 in the connection hole 31 is measured. During the tension of the detection rod 84, the slider 81 is driven to move downward on the linear slide rail 8 through the sensor mounting seat 82, so that the support plate 822 located below the bottom plate 821 of the sensor mounting seat 82 compresses the spring 92 between the support plate 82 and the bottom wall of the through groove 91 inside the spring seat 9. That is, the upward tension of the first slide 54 is finally applied to the spring 92, thereby buffering the detection rod 84 and the tension sensor 83.
[0039] After the pull-out force test of the buckle 32 is completed, the first slide 54 of the first slide cylinder 5 is controlled to move downward, so that the groove 842 on the elastic clip 841 no longer clamps the outer edge of the bottom surface of the buckle 32. At the same time, the second slide of the second slide cylinder 7 is driven to move downward, and the sleeve 11 is pushed to move downward along the detection rod 84 through the sleeve connecting rod 72 and the sleeve mounting seat 10, tightening multiple elastic clips 841, so that when the first slide 54 moves upward, multiple elastic clips 841 can be disengaged from the buckle 32. Then, the second slide of the second slide cylinder 7 is controlled to move upward to reset, and the detection rod 84 drives multiple elastic clips 841 to reset in the sleeve 11 under the action of the spring 92, thus completing the pull-out force test of the buckle 32.
[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
