Description

Technical Field

[0001] This utility model relates to the field of product testing technology, and in particular to a swing test fixture and swing test equipment. Background Technology

[0002] The connection between cables and connectors is usually soldered. After soldering, the solder retention force between the cable and connector needs to be tested to ensure that the cable and connector will not affect the performance of the product when used in the application. For example, when cables and connectors are used in wireless communication systems, they can cause signal interference problems. Therefore, passive intermodulation network analysis (PIM) testing is required.

[0003] In existing technology, before performing passive intermodulation network (PIM) testing, the cable and connector to be tested are connected, and the connector is then fixed to a support plate. Next, the connector is connected to the PIM tester. Then, the end of the cable away from the connector is manually shaken or swung. Since the connector is fixed, the cable's movement relative to the connector causes stress at the solder joint between the cable and connector. The PIM tester displays a fluctuating signal, and the signal is used to determine whether the solder joint holding force between the cable and connector meets the requirements. However, the amplitude of manual shaking or swaying can vary from person to person, leading to inconsistent test results. This can result in products that are actually defective passing the test due to a small shaking amplitude, affecting test accuracy. Utility Model Content

[0005] The second objective of this invention is to provide a swing testing device with high testing accuracy.

[0007] The swing test fixture includes:

[0008] A support assembly, wherein the support assembly is provided with a first mounting hole, and a first test piece is mounted in the first mounting hole;

[0009] An auxiliary test piece is provided, which is disposed opposite to the support assembly in a first direction, and the distance between the auxiliary test piece and the support assembly is adjustable.

[0010] In one embodiment, the support assembly includes a support member and a fixing member, the support member having a second mounting hole, the fixing member being detachably mounted in the second mounting hole, and the first mounting hole being disposed in the fixing member.

[0011] In one embodiment, the swing test fixture further includes a base assembly; at least one of the support assembly and the auxiliary test piece is adjustablely connected to the base assembly along the first direction.

[0012] In one embodiment, the support component is adjustablely connected to the base component along a second direction; the second direction is perpendicular to the first direction.

Furthermore, the terms "first" and "second" are merely used for distinction in description and have no special meaning.

[0043] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on the other component or it can be located in between the component.

[0044] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0045] Firstly, this embodiment provides a swing test fixture, which can improve the consistency of test results and ensure the accuracy of test results.

[0046] The swing test fixture is used in swing test equipment, which can be used to perform passive intermodulation network (PIN) testing on products. PIN testing is a measurement of the nonlinear characteristics of passive components in wireless communication systems, primarily aimed at detecting and mitigating signal interference caused by these components. Passive intermodulation is the intermodulation product generated when two or more radio frequency (RF) signals pass through a nonlinear passive component. These passive components include antennas, cables, connectors, etc. In high-power, multi-channel wireless communication systems, ferromagnetic materials, dissimilar metal solder joints, metal oxide contacts, contaminated components, and loose RF connectors can all lead to PIN problems. The presence of PIN degrades the quality of wireless communication systems, increases base station receiver noise, and may even cause receiver saturation.

[0047] The swing test fixture provided in this embodiment is used to test a first test piece and a second test piece. The first and second test pieces are connected by welding. Exemplarily, the first test piece can be a connector, and the second test piece can be a cable; this embodiment is not limited thereto.

[0048] For example, such as Figures 1 to 10 As shown, the swing test fixture includes a support assembly 100 and an auxiliary test piece 200. The support assembly 100 is used to fix the first test piece 1. Figure 1 As shown, the support assembly 100 is provided with a first mounting hole 110. The first test piece 1 is mounted in the first mounting hole 110. Exemplarily, the first test piece 1 is fixedly mounted in the first mounting hole 110. For example, the first test piece 1 can be fixed to the support assembly 100 by snap-fit, clamping, or other means, which is not limited in this embodiment.

[0049] like Figure 1 and Figure 2 As shown, the auxiliary test piece 200 and the support assembly 100 are arranged opposite each other in the first direction X, and the distance between the auxiliary test piece 200 and the support assembly 100 is adjustable, that is, the distance between the auxiliary test piece 200 and the support assembly 100 in the first direction X is variable, not fixed. The auxiliary test piece 200 is provided with a rotating hole 210, and the second test piece 2 passes through the rotating hole 210. It should be noted that the size of the rotating hole 210 is larger than the cross-sectional size of the second test piece 2, and after the second test piece 2 passes through the rotating hole 210, there is a gap between it and the hole wall of the rotating hole 210.

[0050] When using the swing test fixture provided in this embodiment, the first test piece 1 and the second test piece 2 can be connected first, and then the first test piece 1 is fixed in the first mounting hole 110 for fixation by the support assembly 100. The first test piece 1 is also electrically connected to the testing machine 10 of the swing test fixture via a wire, enabling the testing machine 10 to test the first test piece 1 and the second test piece 2. Then, the second test piece 2 is controlled to pass through the rotating hole 210. During testing, the swing end of the second test piece 2 located on the auxiliary test piece 200 facing away from the support assembly 100 is grasped, and the swing end drives the second test piece 2 to rotate along the wall of the rotating hole 210. At this time, due to the welding position between the first test piece 1 and the second test piece 2, the testing machine 10 will detect a wave signal. The testing machine 10 will determine whether the connection position of the first test piece 1 and the second test piece 2 meets the requirements based on the wave signal.

[0051] The swing test fixture provided in this embodiment has a support component 100 for mounting a first test piece 1. A second test piece 2 passes through a rotation hole 210 in an auxiliary test piece 200. The size of the rotation hole 210 can limit the maximum swing amplitude of the second test piece 2 relative to the first test piece 1, so that the swing amplitude of the second test piece 2 can be controlled. When swinging each second test piece 2, it can be driven with the maximum swing amplitude, so that the swing amplitude of each second test piece 2 can be the same or approximately the same. This ensures the consistency of testing multiple sets of first test pieces 1 and second test pieces 2, reduces the interference of operators on the test results, and is less susceptible to human interference. This improves the test accuracy and reduces the risk of actual non-conforming products appearing as qualified test results.

[0052] Furthermore, by adjusting the size of the rotating hole 210 and the distance between the auxiliary test piece 200 and the support component 100, the testing requirements of different products can be met, making the swing test fixture more widely applicable and more versatile.

[0053] For example, such as Figure 3 As shown, the support assembly 100 includes a support member 120 and a fixing member 130. The support member 120 has a second mounting hole 121, and the fixing member 130 is detachably mounted in the second mounting hole 121. The fixing member 130 also has a first mounting hole 110 for fixing the first test piece 1. By providing a fixing member 130 detachably connected to the support member 120, the fixing member 130 can be separated from the support member 120 when the first test piece 1 is installed in the first mounting hole 110, facilitating the connection between the support member 120 and the first test piece 1 and reducing the difficulty of installing the first test piece 1. In some optional embodiments, the detachable connection between the fixing member 130 and the support member 120 can be a snap-fit, bolt connection, etc., which is not limited in this embodiment.

[0054] For example, such as Figure 3 As shown, the fixing member 130 can be a plate, and the support member 120 can be a plate. The support member 120 is bolted to the side of the fixing member 130 facing the auxiliary test piece 200.

[0055] To improve the overall integrity of the support component 100 and the auxiliary test piece 200, in one possible implementation, such as Figure 1 As shown, the swing test fixture also includes a base assembly 300. At least one of the support assembly 100 and the auxiliary test piece 200 is adjustablely connected to the base assembly 300 along a first direction X, allowing the distance between the support assembly 100 and the auxiliary test piece 200 in the first direction X to be adjustable. By setting the base assembly 300, the support assembly 100 can be connected to the base assembly 300, and the auxiliary test piece 200 can also be connected to the base assembly 300. The support assembly 100, the auxiliary test piece 200, and the base assembly 300 are connected as a whole, facilitating the movement and transportation of the swing test fixture, and also facilitating the control of the relative position of the support assembly 100 and the auxiliary test piece 200 in a direction perpendicular to the first direction X to meet testing requirements.

[0056] It should be noted that there are several ways in which the support component 100 and / or the auxiliary test piece 200 can be adjusted to be connected to the base component 300. For example, the base component 300 may have multiple connection positions, and the support component 100 and / or the auxiliary test piece 200 may be connected to one of these connection positions via bolts or other connecting structures. Alternatively, the support component 100 and / or the auxiliary test piece 200 may be slidably connected to the base component 300. When slid to a preset position, it is locked to the base component 300 by a locking element. The locking element may be a snap fastener provided on the support component 100 and / or the auxiliary test piece 200, which can engage with the base component 300 to lock the support component 100 and / or the auxiliary test piece 200 to the base component 300.

[0057] In some optional embodiments, the support assembly 100 is adjustablely connected to the base assembly 300 along the second direction Y. The second direction Y is perpendicular to the first direction X; for example, the first direction X is the thickness direction of the support member 120, and the second direction Y is the length or height direction of the support member 120. This embodiment does not limit this. By setting the support assembly 100 to be adjustablely connected to the base assembly 300 along the second direction Y, the position of the support assembly 100 relative to the auxiliary test piece 200 in the second direction Y can be adjusted according to the specific structure of the first test piece 1 and the second test piece 2, thereby further improving the accuracy of the test. In this embodiment, the second direction Y is exemplified as the height direction of the support member 120.

[0058] It is understandable that the auxiliary test piece 200 can be adjustablely connected to the base assembly 300 along the second direction Y, and can also adjust the relative position of the first test piece 1 and the second test piece 2 in the second direction Y, so as to further improve the accuracy of the test.

[0059] In some alternative embodiments, the base assembly 300 can be a split structure, such as... Figure 4 As shown, the base assembly 300 includes a base 310, a first connector 320, and a second connector 330. The first connector 320 is adjustablely connected to the base 310 along a first direction X. The support assembly 100 is connected to the first connector 320, and thus adjustablely connected to the base 310 via the first connector 320. Specifically, when the support assembly 100 includes a support member 120 and a fixing member 130, the fixing member 130 is connected to the first connector 320. The second connector 330 is adjustablely connected to the base 310 along the first direction X. The auxiliary test piece 200 is connected to the second connector 330, so that its position is adjustable via the second connector 330, thereby achieving adjustable spacing between it and the support assembly 100 in the first direction X.

[0060] Optionally, such as Figure 4 As shown, the first connector 320 can be a column, and the second connector 330 can also be a column. The first connector 320 and the second connector 330 extend along the second direction Y. The first connector 320 and the second connector 330 can also both be plates, but this embodiment does not limit this.

[0061] Multiple first connectors 320 can be provided to improve the support effect on the support assembly 100. Multiple second connectors 330 can also be provided to improve the support effect on the support assembly 100.

[0062] For example, the base 310 is composed of two parallel columns, which makes the structure of the base 310 simpler, lighter, and less expensive. Of course, it is understood that the base 310 can also be formed of a plate, and this embodiment does not limit it to this.

[0063] In one possible implementation, such as Figure 4As shown, the first connecting member 320 is connected to the base 310 via a first connecting block. The first connecting block is L-shaped, with one end connected to the base 310 and the other end connected to the first connecting member 320. To facilitate the alignment of the first connecting member 320 and the first connecting block, the first connecting block is provided with a first positioning structure 341, and the first connecting member 320 is provided with a first mating structure (not shown in the figure) that matches the first positioning structure 341. The first positioning structure 341 and the first mating structure engage in a snap-fit ​​engagement, thereby achieving the pre-positioning of the first connecting member 320 and the first connecting block, which is then fixedly connected by bolts or other fixing structures.

[0064] Similarly, such as Figure 4 As shown, the second connecting member 330 is connected to the base 310 via a second connecting block. The second connecting block is L-shaped, with one end connected to the base 310 and the other end connected to the second connecting member 330. To facilitate the alignment of the second connecting member 330 and the second connecting block, the second connecting block is provided with a second positioning structure 351, and the second connecting member 330 is provided with a second mating structure (not shown in the figure) that matches the second positioning structure 351. The second positioning structure 351 and the second mating structure engage in a snap-fit ​​connection, thereby achieving the pre-positioning of the second connecting member 330 and the second connecting block, which is then fixedly connected by bolts or other fixing structures.

[0065] It is understandable that the base assembly 300 can also be a one-piece structure, but this embodiment does not limit this.

[0066] Since the first test piece 1 and the second test piece 2 are typically plugged in and then welded together, they are usually coaxial. To improve the uniformity of testing the connection position of the first test piece 1 and the second test piece 2, the rotating hole 210 can optionally be coaxially arranged with the first mounting hole 110, that is, the axis of the rotating hole 210 is collinear with the axis of the first mounting hole 110. With this arrangement, when the second test piece 2 is controlled to swing, the connection position of the first test piece 1 and the second test piece 2 is subjected to uniform force along the circumferential direction, thereby enabling the testing of the welding condition at each position of the connection between the first test piece 1 and the second test piece 2, and further improving the accuracy of the test results.

[0067] The shape of the rotating hole 210 can be set according to the test requirements, for example, such as Figure 4 As shown, in this embodiment, the rotating hole 210 is a circular hole, so the movement path of the second test piece 2 during swinging is circular. In other embodiments, the rotating hole 210 can also be a polygonal hole, for example, as shown in... Figure 10 As shown, the rotating hole 210 is a triangular hole. In other embodiments, such as... Figure 9As shown, the rotating hole 210 can also be a cross-shaped hole. In other embodiments, the rotating hole 210 can also be a fan-shaped hole, an elliptical hole, etc., and this embodiment does not limit it.

[0068] Optionally, such as Figure 6 As shown, the swing test fixture also includes a rotating member 400. The rotating member 400 is rotatably disposed on the wall of the rotating hole 210. The side wall of the rotating member 400 contacts the second test piece 2, thereby reducing friction on the second test piece 2 and adjusting the sliding friction between it and the second test piece 2 to rolling friction as much as possible, thus reducing the wear on the second test piece 2 and ensuring its functionality.

[0069] The rotating component 400 includes, but is not limited to, a roller shaft, which is rotatably mounted on the auxiliary test component 200 via a U-shaped connecting rod. For example, the middle section of the connecting rod is parallel to the wall of the rotating hole 210, and the roller shaft is sleeved on the middle section and can rotate around the middle section. That is, the axial direction of the roller shaft is the same as the axial direction of the rotating hole 210.

[0070] For example, multiple rotating members 400 are provided, and the multiple rotating members 400 are arranged circumferentially along the rotating hole 210. There may be a certain interval between two adjacent rotating members 400, or they may be arranged close together. This embodiment does not limit this.

[0071] Secondly, this embodiment also provides a swing testing device with high testing accuracy.

[0072] like Figures 7 to 10 As shown, the swing test equipment includes the aforementioned swing test fixture. The swing test equipment also includes a test machine 10, with the first test piece 1 electrically connected to the test machine 10. Specifically, one end of the first test piece 1 is connected to the second test piece 2, and the other end is electrically connected to the test machine 10.

[0073] It should be noted that the testing machine 10 includes, but is not limited to, a passive intermodulation network testing device, which enables the swing test fixture provided in this embodiment to not only test the welding strength of the first test piece 1 and the second test piece 2, but also to test the passive intermodulation performance of the product composed of the first test piece 1 and the second test piece 2. Moreover, the two tests are performed simultaneously, which improves testing efficiency, reduces testing difficulty, and has high testing accuracy.

[0074] In some alternative embodiments, such as Figure 7As shown in the figure, the testing machine 10 is disposed on the side of the support component 100 facing away from the auxiliary test piece 200. With such a setting, the first test piece 1 is disposed through the first mounting hole 110, and one end of the first test piece 1 is electrically connected (specifically, conductively connected) to the second test piece 2, and the other end is electrically connected (specifically, conductively connected) to the testing machine 10, so that the connection between the first test piece 1 and the testing machine 10 does not affect the swing of the second test piece 2, ensuring the smooth progress of the test, and also making the component distribution of the entire swing testing device more reasonable.

[0075] When the swing testing device provided in this embodiment is in use, first select the first test piece 1 according to the second test piece 2, then select the fixing piece 130 that matches the first test piece 1, and then fixedly connect the first test piece 1 and the fixing piece 130. After that, install the fixing piece 130 in the second mounting hole 121 to achieve the fixed connection between the fixing piece 130 and the support piece 120. After that, electrically connect the first test piece 1 to the testing machine 10 and connect the second test piece 2 to the first test piece 1. Then, select the appropriate auxiliary test piece 200 for the rotation hole 210 according to requirements, and pre-install the auxiliary test piece 200 on the base 310 through the second connecting piece 330. After that, adjust the position of the auxiliary test piece 200 according to the spacing requirement between the auxiliary test piece 200 and the support piece 120 (for example, the spacing requirement is 300 mm or other distances). Next, rotate and swing the second test piece 2 along the edge of the rotation hole 210, and the testing machine 10 starts to work synchronously. During the test, the passive intermodulation network analysis data and the fluctuations during the selection of the rotating product will be presented on the screen of the testing machine 10. If the fluctuations of the product are within the set range, it is determined that the product is qualified. If the fluctuations of the product are not within the set range, the unqualified items will be specifically displayed. The solder joint information is presented without disassembling the product, and it is automatically judged according to the system data whether the product can be repaired. If it can be repaired, it is retested after repair. If it cannot be repaired, it is scrapped or disassembled and replaced with parts.

[0076] The swing testing device provided in this embodiment is easy to operate, more intelligent, and has a lower cost, realizing the functions of increasing the swing products and making the passive intermodulation test more perfect and stable. It solves the problem of the outflow of defective product tests and has the advantage of improving the product quality.

[0077] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
