Technical Field
[0001] This application relates to the field of electronic equipment testing technology, and in particular to a special fixture for testing electronic equipment. Background Technology
[0002] As electronic devices become increasingly diverse, ranging from smartphones and computers to industrial control modules and precision sensors, their internal structures are becoming more complex, leading to ever-increasing demands for testing accuracy and stability. During the production, repair, and quality inspection of electronic equipment, specialized fixtures are required to stably secure the equipment or its internal components, enabling testing personnel to perform circuit continuity tests, signal analysis, or troubleshooting.
[0003] In the prior art, traditional fixtures for testing electronic devices typically employ a rigid clamping structure with fixed dimensions. For example, the utility model patent with publication number CN221686455U, entitled "Special Fixture for Testing Electronic Devices," uses a movable rigid clamp to hold the four side walls of the electronic device. However, traditional fixtures for testing electronic devices lack flexible buffering during clamping, and the rigid clamping blocks are in direct contact with the device surface, easily causing scratches on precision components and indentations on the casing. Furthermore, the clamping size adjustment range is limited, making it difficult to adapt to electronic devices of different specifications, such as those with significant differences in length and thickness. Frequent fixture changes are required when changing the object being tested, resulting in cumbersome operation and poor versatility.
[0004] Therefore, it is necessary to improve one or more of the problems existing in the above-mentioned related technical solutions.
[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

They are also fixedly connected to the top surface of the two L-shaped toothed plates by a fixing member that slides through the slide. The two clamping components have multiple elastic telescopic members on opposite sides.
[0008] In one possible implementation, the adjusting assembly further includes: a gear, a worm gear, and a worm; The gear meshes with the two L-shaped toothed plates; The worm gear is coaxially and fixedly connected to the gear, and cooperates with the worm. The two ends of the worm gear are rotatably mounted on the side wall of the support assembly, with one end extending out of the side wall of the support assembly.
[0009] In one possible implementation, the outer side of the L-shaped toothed plate parallel to the slide rail has a groove, and the raised slide rail is slidably engaged in the groove.
[0010] In one possible implementation, the fixing member is located at the top of one end of the L-shaped toothed plate perpendicular to the slide, and the fixing member passes through the slide and is fixedly connected to the bottom of the clamping assembly.
[0011] In one possible implementation, the end of the worm extending out of the sidewall of the support assembly has a crank handle.
[0012] In one possible implementation, the clamping assembly includes a plurality of mounting blocks and a plurality of resilient telescopic members; The mounting block has multiple mounting holes, and the elastic telescopic member is disposed in the mounting holes for retracting into the mounting holes when subjected to pressure toward the mounting holes, and extending out of the mounting holes when not subjected to pressure.

[0017] The technical solution provided in this application may include the following beneficial effects: This application describes a special fixture for testing electronic equipment. It allows two L-shaped toothed plates to slide along a slide rail via an adjustment component inside the support assembly, causing two connected clamping components to move synchronously relative to each other, thus enabling flexible clamping of electronic devices of varying widths.

[0020] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided to make this application more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
[0021] Furthermore, the accompanying drawings are merely illustrative of this application and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore, repeated descriptions of them will be omitted.
[0022] This example embodiment first provides a special fixture for testing electronic devices. (Reference) Figure 1 As shown, the special fixture for testing electronic devices includes a support assembly 100, an adjustment assembly 200, and two clamping assemblies 300.
[0023] The support component 100 has an internal cavity and a slide 110 on its top surface that communicates with the cavity. The adjustment assembly 200, located inside the cavity, includes two L-shaped toothed plates 210 slidably connected to the inner wall of the cavity, used to control the two L-shaped toothed plates 210 to slide along the slide rail 110 during adjustment; Two clamping assemblies 300 are respectively located at both ends of the slide rail 110 and slidably connected to the top surface of the support assembly 100. They are also fixedly connected to the top surface of the two L-shaped toothed plates 210 by means of a fixing member 212 that slides through the slide rail 110. The two clamping assemblies 300 have multiple elastic telescopic members on opposite sides.
[0024] The aforementioned specialized fixture for electronic equipment testing enables stable and flexible clamping of electronic devices of different specifications, while offering convenient operation and strong adaptability. Specifically, the sliding engagement of the L-shaped toothed plate 210 in the adjusting component 200 allows the two clamping components 300 to move precisely relative to or away from each other, thus accommodating electronic devices of varying widths. Simultaneously, multiple elastic telescopic components on the clamping component 300 retract upon contact with the equipment, creating a buffer and preventing damage to the surface and internal precision components caused by rigid clamping. Furthermore, the modular design of each component facilitates adjustment of the overall dimensions of the clamping component 300 according to testing requirements, further enhancing the fixture's versatility and practicality.
[0025] In one embodiment, the adjustment assembly 200 further includes: a gear 220, a worm gear 230, and a worm 240; The gear 220 meshes with the two L-shaped toothed plates 210; The worm gear 230 is coaxially and fixedly connected to the gear 220, and cooperates with the worm 240; The two ends of the worm gear 240 are rotatably mounted on the side wall of the support assembly 100, and one end extends out of the side wall of the support assembly 100.
[0026] It should be noted that the meshing relationship between gear 220 and the two L-shaped toothed plates 210 converts the rotational motion of gear 220 into the opposite synchronous linear motion of the two L-shaped toothed plates 210, thereby realizing the opening and closing action of the clamping assembly 300. The cooperation between worm gear 230 and worm 240 utilizes their unidirectional transmission characteristics, allowing worm gear 230 and gear 220 to rotate only through worm 240; otherwise, transmission is impossible. This ensures that the clamping assembly 300 maintains a stable clamping state after adjustment, preventing loosening due to external forces.
[0027] In one embodiment, the upper part of the two side walls of the support assembly 100 parallel to the slide rail 110 has a raised slide rail 130, and the outer side of the L-shaped toothed plate 210 parallel to the slide rail 110 has a slide groove 211, and the raised slide rail 130 is slidably engaged in the slide groove 211.
[0028] It should be noted that the sliding engagement between the raised slide rail 130 and the slide groove 211 provides guidance for the movement of the L-shaped toothed plate 210, ensuring that it slides smoothly along the slide rail 110 and avoids deviation. At the same time, this structure provides longitudinal restraint for the L-shaped toothed plate 210, preventing it from disengaging from the cavity of the support component 100 and ensuring the stable operation of the adjustment component 200.
[0029] Furthermore, the fixing member 212 is located at the top of the end of the L-shaped toothed plate 210 that is perpendicular to the slide rail 110, and the fixing member 121 passes through the slide rail 110 and is fixedly connected to the bottom of the clamping assembly 300.
[0030] It should be noted that the fixing member 212 is a key component connecting the L-shaped toothed plate 210 and the clamping assembly 300. It can directly transmit the sliding of the L-shaped toothed plate 210 to the clamping assembly 300, realizing the synchronous movement of the two. The slide rail 110 provides movement space for the fixing member 212, while restricting the movement direction of the clamping assembly 300 to ensure adjustment accuracy.
[0031] Optionally, the end of the worm gear 240 extending out of the side wall of the support assembly 100 has a crank handle 241.
[0032] It should be noted that the crank handle 241 provides a convenient operating interface for users. By turning the crank handle 241, the worm gear 240 can be rotated, thereby driving the entire adjustment assembly 200 to operate. The crank handle 241 increases the lever arm length, making the adjustment process less strenuous and improving operational convenience.
[0033] In one embodiment, the special fixture for testing electronic devices is characterized in that the clamping assembly 300 includes a plurality of mounting blocks 310 and a plurality of elastic telescopic members; The mounting block 310 has a plurality of mounting holes 340, and the elastic telescopic member is disposed in the mounting holes 340 for retracting into the mounting holes 340 when subjected to pressure toward the mounting holes 340, and extending out of the mounting holes 340 when not subjected to pressure.
[0034] It should be noted that the combined design of multiple mounting blocks 310 allows for adjustment of the overall length or height of the clamping assembly 300 according to the size of the electronic device, enhancing adaptability. The telescopic characteristics of the elastic telescopic component enable flexible clamping of the electronic device, avoiding damage caused by rigid contact, while providing stable clamping force through elasticity.
[0035] Furthermore, the special fixture for testing electronic devices is characterized in that the elastic telescopic member includes a clamping member 320 and a spring 330; The mounting hole 340 has a limiting block 341, the limiting block 341 has a first through hole in the middle, the clamping member 320 passes through the first through hole, has a contact end at the top and a limiting member at the bottom; the spring 330 is disposed between the contact end and the limiting block 341.
[0036] Understandably, the cooperation between the limiting block 341 and the limiting member restricts the maximum extension of the clamping member 320, preventing it from disengaging from the mounting hole 340. The elastic force of the spring 330 acts on the electronic device through the contact end, providing sufficient clamping force and adapting to deformation when there are slight differences in the device size, thus improving clamping flexibility.
[0037] In one embodiment, the mounting block 310 has a mounting groove 311 at the top and a mounting protrusion 312 at the bottom, and a plurality of the mounting blocks 310 are fixed by being slidably inserted into the mounting groove 311 through the mounting protrusion 312.
[0038] It should be noted that the plug-in structure between the mounting protrusion 312 and the mounting groove 311 enables quick assembly and disassembly of the mounting block 310. Users can increase or decrease the number of mounting blocks and flexibly adjust the specifications of the clamping assembly 300 according to their needs. This modular design facilitates maintenance, and individual mounting blocks 310 can be replaced when damaged, reducing operating costs.
[0039] Optionally, the contact end of the clamping member 320 is a flexible contact end.
[0040] It should be noted that flexible contact ends, such as those made of rubber or silicone, can reduce wear on the surface of electronic devices during clamping, preventing scratches on the casing or precision components. At the same time, the friction of the flexible material can prevent the device from slipping during testing, improving clamping stability.
[0041] In one embodiment, the support assembly 100 has a removable bottom cover 120 at its bottom.
[0042] It should be noted that the bottom cover 120 is removable, which facilitates the inspection or replacement of the adjustment component 200 inside the support assembly 100, extending the service life of the fixture. At the same time, the bottom cover 120 can prevent dust from entering the cavity, thus avoiding affecting the operating accuracy of the adjustment component 200.
