Description

Technical Field

[0001] This utility model relates to the field of device testing fixture technology, and in particular to a crystal oscillator aging fixture. Background Technology

[0002] With the continuous advancement of science and technology, crystal oscillators, possessing advantages such as high frequency accuracy, small footprint, strong anti-interference capability, and long lifespan, have become a crucial component in modern electronics. The frequency aging characteristics and standard requirements of crystal oscillators are key aspects of their application. The frequency aging characteristics of a crystal oscillator refer to the frequency changes after prolonged operation. After a period of operation, frequency deviations gradually appear; in some cases, the frequency changes are very large, and this change is called frequency aging. One of the most significant factors affecting the frequency aging characteristics of crystal oscillators is temperature. The crystal and electronic components in a crystal oscillator are very sensitive, and their characteristics change due to temperature. During operation, if the ambient temperature of the crystal oscillator differs or changes, the oscillator's frequency will also change accordingly.

[0003] Currently, aging performance testing of crystal oscillators is typically conducted using specialized aging test fixture systems. This involves clamping the crystal oscillator in a suitable test fixture, which is then connected to an aviation connector via probes. The aviation connector is connected to a dedicated test board via wires. The test board's test circuitry, along with multiplexers and switching mechanisms, allows for the sampling and transmission of frequency data, enabling precise and stable frequency testing and aging performance evaluation of the crystal oscillator. Existing test fixtures typically use pre-cut adapter slots with spring-loaded probes at the bottom to position and abut against the crystal oscillator's pins. Aging tests are then performed using a test board or other testing system connected to the fixture. However, existing aging test fixtures are usually manufactured using a dedicated method, meaning each fixture can typically only accommodate one type and size of crystal filter, limiting its applicability to various crystal filter models. Especially in the early stages of crystal filter design and manufacturing, multiple small batches of crystal filter samples with varying sizes are usually designed and manufactured. To obtain the actual performance of the samples, multiple performance testing processes, such as aging tests, are usually required. Therefore, test fixtures are needed to clamp and limit the connection of the samples. Due to the small batch size and diverse dimensions, conventional test fixtures cannot effectively adapt to the clamping. Furthermore, the cost of conventional single-mold production of dedicated test fixtures is high and cannot be used for the test clamping of crystal filters in the sample development stage. There is an urgent need for a crystal oscillator aging fixture that can adaptably clamp and limit the connection of small batches of crystal filters of various sizes in the sample development stage. Utility Model Content

[0004] The purpose of this invention is to provide a crystal oscillator aging fixture that can adjust for the adaptive clamping of various crystal oscillators of different sizes and specifications, thereby improving the applicability of small-batch testing and reducing the manufacturing cost of the fixture. This solves the problems of existing single aging test fixtures, which can usually only clamp crystal oscillators of one model and size and cannot adapt to clamping multiple different models of crystal oscillators, resulting in a limited applicability. It also addresses the problem that conventional single-mold production of dedicated test fixtures is too costly and cannot be used for testing and clamping crystal oscillators in the sample development stage.

[0023] The technical solutions provided by this utility model will be described in detail below with reference to the accompanying drawings and through embodiments. It should be noted that the descriptions of these embodiments are for the purpose of helping to understand this utility model, but do not constitute a limitation thereof. In some examples, because some implementation methods belong to existing or conventional technology, they are not described or are not described in detail. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and do not have any sequential or technical meaning.

[0024] The following is a detailed explanation with reference to the accompanying drawings.

[0025] Example 1

[0026] This application provides a crystal oscillator aging fixture, which includes a mounting base 1, a parallel guide rail mechanism 2, a mounting stage 3, a clamping assembly 4, a suspended frame 5, and a pressing positioning assembly 6.

[0027] according to Figure 1-3 In one specific embodiment, the mounting base 1 provides a raised mounting surface for convenient installation of various functional accessories. Four sets of parallel guide rail mechanisms 2 are arranged in a rotationally symmetrical manner on the top surface of the mounting base 1. A mounting platform 3 is detachably mounted on the central surface region of the mounting base 1 between the four sets of parallel guide rail mechanisms 2. A clamping assembly 4 is mounted on the sliding end of each parallel guide rail mechanism 2, capable of synchronously moving with it and adjusting to abut against the side edge of the crystal oscillator for clamping and limiting the crystal oscillator. A suspended frame 5 is also supported on the mounting base 1, forming a suspended mounting surface above the mounting platform 3. A pressing and positioning assembly 6 is provided on the suspended frame 5 to press and limit the crystal oscillator mounted on the mounting platform 3. The mounting platform 3 provided in this application can adjust the relative positions of the four spring probes 33 as needed, so that the spring probes 33 can accurately correspond to the pin positions of crystal oscillators of different sizes, thereby ensuring the effectiveness of the test connection. The clamping component 4 provided in this application can adaptably clamp crystal oscillators of different widths by pre-adjusting the distance between the aligned clamping plates 44, which are driven by the pressing and positioning component 6 to move in opposite directions. This expands the applicability of the fixture for clamping and limiting crystal oscillators of different specifications. The pressing and positioning component 6 provided in this application can effectively press and limit crystal oscillators of different thicknesses after its initial height is adjusted and it descends at a fixed distance. This application adaptably clamps crystal oscillators of different models and sizes by using the independent adjustability of the mounting platform 3, the clamping component 4, and the pressing and positioning component 6. Compared with existing dedicated fixtures, the fixture constructed in this application can reduce the fixture cost investment in the small batch design stage and eliminate the need for frequent mold opening and manufacturing of fixtures of various specifications.

[0028] Preferably, the mounting base 1 includes a mounting plate 11, support columns 12, and a base plate 13. Specifically, the mounting plate 11 is suspended on the base plate 13 by the support columns 12 connected to its four corners, thereby forming a space below it that can accommodate the downwardly moving adjustable trapezoidal plate 67. Specifically, the upper and lower axial ends of the support columns 12 are integrally connected to the mounting plate 11 and the base plate 13, respectively, i.e., all three are integrally injection molded from reinforced plastic. Preferably, the mounting plate 11 has a notch 111 that can accommodate the ramp push block 411 and the adjustable trapezoidal plate 67. Preferably, the mounting plate 11 is provided with an elastic clip that can abut against the side of the pedestal 31 to limit the stability of the pedestal 31 during installation.

[0029] Preferably, the parallel guide rail mechanism 2 includes two parallel rails 21 spaced apart and embedded in the top surface of the mounting base 1, a slider 22 slidably installed in the rail cavity of the rail 21 and capable of reciprocating, and an elastic positioning member 23 capable of positioning the slider 22 in the initial installation position in the rail 21 and resetting the slider 22 after it has shifted. Specifically, the four sets of parallel guide rail mechanisms 2 have eight rails 21, so that the sliders 22 slidably embedded in the two rails 21 of the same group can be connected to the same T-shaped platform 41 to ensure the stability of the sliding support. The slider 22 is securely connected to the T-shaped 41 by welding, bolt flange connection or other means. The side of the slider 22 inside the track 21 and the end face of the track 21 are respectively fixedly connected to the two ends of the horizontal spring, which serves as the elastic positioning element 23. Thus, the elastic positioning element 23 is used to limit the initial position of the slider 22 in the track 21. After the slider 22 slips and the external force is removed, the horizontal spring, which serves as the elastic positioning element 23, can also drive the slider 22 to move back to its original position under the action of the return spring force.

[0030] Preferably, the base 31 of the mounting platform 3 is detachably embedded in the center of the mounting plate 11 of the mounting base 1. Preferably, two alignment mechanisms 32 are adjustablely embedded in the base 31. More preferably, spring probes 33 are inserted at both ends of the alignment mechanism 32, so that the size of the rectangular frame constructed by the four spring probes 33 can be adjusted as needed, thereby adaptably contacting and connecting with the four pins of crystal oscillators of different specifications and models. More preferably, the spring probes 33 are connected to the ports of aging test equipment such as aging test boards via connecting wires with aviation plugs. That is, aviation plugs with connecting wires are inserted into the ports of aging test equipment such as aging test boards, and the aviation plugs can be fitted and connected to the spring probes in a compatible manner. Thus, after the crystal oscillator is clamped in the aging test fixture, the crystal oscillator is connected to the test equipment by connecting the aviation plugs to the lower ends of the spring probes, thereby using the test equipment for performance testing. Preferably, the spring probe 33 can be the spring probe disclosed in patent document CN208334440U, and a probe insertion seat 324 is provided in the base 31 of this application, corresponding to the probe seat in the prior art. The exposed end of the spring probe at the bottom of the probe seat is connected via an aviation plug. Preferably, the aging test equipment can be the Delta Instruments GS-LHCSJ series plate-type universal aging system. This series of test equipment has a modular carrier board, and the carrier board has a screw hole interface (M4 standard). The connection between the spring probe 33 and the gold-plated pad of the carrier board is achieved by inserting the conductive screw at the end of the wire into the screw hole interface. The carrier board has a built-in 50Ω impedance matching circuit, and is then connected to the main control port of the equipment via an FPC cable. The error is <±5ppm. This system is mainly used for testing crystal oscillators in consumer electronics.

[0031] Preferably, two receiving grooves 311 are aligned on the top surface of the base 31 to accommodate the adjusting mechanism 32. Preferably, a guide through groove 312 for adjusting the locking rod 322 of the adjusting mechanism 32 is also provided on the bottom surface of the receiving groove 311. More preferably, extended through grooves 313 for accommodating the spring probe 33 are also provided on both sides of the guide through groove 312.

[0032] Preferably, the adjustment mechanism 32 includes a horizontal square rod 321, a locking vertical rod 322, an adjusting sleeve 323, a probe insert 324, a limiting nut 325, and a locking screw 326. Preferably, the upper axial end of the locking vertical rod 322 is connected to the horizontal square rod 321. Preferably, both ends of the horizontal square rod 321 are fitted with adjusting sleeves 323. More preferably, a locking screw 326 is also inserted into the adjusting sleeve 323 to limit its relative position to the horizontal square rod 321. Preferably, the end of the adjusting sleeve 323 away from the horizontal square rod 321 is connected to the probe insert 324. Preferably, the locking vertical rod 322, passing through the guide through groove 312 and located below the base 31, is also threaded with a limiting nut 325 to adjustably limit the position of the locking vertical rod 322 in the guide through groove 312, thereby adjusting the position of the adjusting mechanism 32 in the receiving groove 311, and changing the distance between the two probe insert seats 324 by adjusting the length of the horizontal square rod 321 inserted into the adjusting sleeve 323. Preferably, the locking vertical rod 322 includes an upper rectangular rod that can cooperate with the guide through groove 312 to limit its reciprocating translation and a lower threaded round rod that can be fitted with the limiting nut 325. Preferably, the spring probe 33 is vertically inserted into the probe insert seat 324 by means of interference fit or other methods. The adjustment mechanism 32 provided in this application can change the distance between the two probes in the longitudinal direction by adjusting the position of the locking vertical rod 322 in the guide through groove 312, and change the distance between the two probes in the transverse direction by changing the overlapping insertion length of the horizontal square rod 321 and the adjusting sleeve 323. This allows the size of the rectangular frame defined by the four probes to be changed according to the requirements, so that the four probes can be adapted to be effectively connected to the four pins of different crystal oscillators one by one.

[0033] Preferably, the clamping assembly 4 includes a T-shaped platform 41 that can be simultaneously connected to sliders 22 arranged in two parallel tracks 21, an adjusting screw 42 threaded onto the T-shaped platform 41, a rectangular guide slide rod 43 slidably passing through the T-shaped platform 41 and aligned with both sides of the adjusting screw 42, and a clamping strip 44 connected to the ends of the adjusting screw 42 and the rectangular guide slide rod 43. Before use, depending on the size of the crystal oscillator being clamped, the user can push and pull the clamping strip 44 by turning the adjusting screw 42 to move it, thereby changing the distance between the clamping strip 44 and the T-shaped platform 41 as needed. This allows the clamping strip 44 to adaptably clamp and limit various crystal oscillators of different sizes. Preferably, the surface of the rectangular guide slide rod 43 is also provided with a scale, so that the operator can easily make specific length adjustments according to the scale. Preferably, the side of the T-shaped platform 41 away from the clamping strips 44 is also provided with inclined sliding vertical plates 411 symmetrically distributed along the axis of the adjusting screw 42 and embedded in the platform. The clamping strips 44 provided in this application can be translated towards the center during the downward pressure of the adjusting trapezoidal plate 67 to push the inclined sliding vertical plates 411. Thus, the four clamping strips 44 around the crystal oscillator are arranged in pairs and equivalently translated to achieve the centering and clamping limitation of the crystal oscillator, allowing the crystal oscillator to be centrally positioned on the platform 31. The adjusting screw 42 provided in this application can adjust the distance between two aligned clamping strips 44 as needed, allowing the aligned clamping strips 44 to adaptably clamp crystal oscillators of different sizes. Furthermore, adjacent clamping strips 44 can have different distances from the central axis, thus adapting to the clamping of crystal oscillators with different rectangular block configurations. The four clamping plates 44 provided in this application undergo equal translation during the downstream process of the pressing and positioning assembly 6. The clamping of crystal oscillators of different sizes is mainly achieved by changing the distance between the T-shaped stage 41 and the clamping plates 44.

[0034] Preferably, the suspended frame 5 includes four corner supports 51 supported on the mounting base plate 11 and a suspended mounting plate 52 connected to the corner supports 51. Specifically, the top and bottom ends of the corner supports 51 can be assembled with the suspended mounting plate 52 and the mounting base 11 by means of welding or bolt flange connection. Preferably, the suspended mounting plate 52 is connected to the lifting adjustment sleeve 61 by means of welding, flange connection or countersunk screw insertion connection.

[0035] Preferably, the pressing positioning assembly 6 includes a lifting adjustment sleeve 61 fixedly inserted into the suspended mounting plate 52, an internally threaded sleeve 62 movably inserted into the lifting adjustment sleeve 61, a threaded vertical rod 63 inserted from the lower end opening of the internally threaded sleeve 62, and a pressing positioning seat 64 connected to the axial lower end of the threaded vertical rod 63. Preferably, a vertical return spring 65 is fitted on the tube body of the internally threaded sleeve 62 above the suspended mounting plate 52. More preferably, the top end of the internally threaded sleeve 62 is also provided with an adjusting top seat 66 to facilitate manual adjustment of its working position and prevent the vertical return spring 65 from falling off. Preferably, a mounting plate 68 is fitted on the tube body of the internally threaded sleeve 62 below the lifting adjustment sleeve 61, and an adjusting angle plate 67 corresponding to the plurality of inclined pushing vertical plates 411 is also provided on the side edge of the mounting plate 68. The internal threaded sleeve 62 and threaded vertical rod 63 provided in this application can have their lengths changed by adjusting the length of their threaded insertion connection. This allows the quantitatively descending pressure positioning seat 64 to adaptably abut against the top surface of crystal oscillators of different sizes, effectively pressing the crystal oscillator against the base 31 and ensuring the stability of the limit position. The adjusting top seat 66 provided in this application is a manually operated gripping structure, which is a connection between a disc and a vertical plate. The operator changes the working position of the pressure positioning seat 64 by pressing down and rotating the adjusting top seat 66, and can also lock and limit the relative position between the lifting adjusting sleeve 61 and the internal threaded sleeve 62 by relative rotation, so as to maintain the downward limiting posture.

[0036] Preferably, a vertical guide groove 611 and a transverse limiting groove 612 connected to the lower end of the vertical guide groove 611 are provided on the inner wall of the lifting and adjusting sleeve 61. Preferably, a limiting protrusion 621 is provided on the outer wall of the internal threaded sleeve 62, which can move in the vertical guide groove 611 and the transverse limiting groove 612 and cooperate with the vertical return spring 65 to limit the working position of the internal threaded sleeve 62. Specifically, the limiting protrusion 621 can move from the vertical guide groove 611 into the transverse limiting groove 612 during the downward movement and rotation of the internal threaded sleeve 62, thereby limiting the position of the internal threaded sleeve 62 in the lifting and adjusting sleeve 61, and thus limiting the downward pressing contact condition.

[0037] Preferably, the electrical components such as the aging test equipment involved in this application are all electrically connected to the controller and the power supply. The control method of this application is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is only used to protect the mechanical device and its mechanical structural features. Therefore, this utility model will not explain the control method and circuit connection in detail.

[0038] For surface connections between components not explicitly specified in this application, conventional bolt connections, snap-fit ​​connections, or fixed connections such as welding can be used. As these are conventional connection methods, this application will not elaborate further on this part. Specifically, the connecting ends of the assembled components all form flange structures, and the two flange structures are connected by bolts, gaskets, or other structures.
