DETAILED DESCRIPTION
[0023] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. Figures 1 to 4 The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0024] It should be noted that some terms are used in the specification and claims to refer to particular components. One of skill in the art will understand that the person skilled in the art can use different names to refer to the same component. The description and claims should not be limited to the names used for the components, but should be construed to cover the components that serve the same function. As used throughout the specification and claims, "comprising" or "including" is to be construed as meaning "including but not limited to." The subsequent description is described as a preferred embodiment for implementing the present disclosure, and the description is for the purpose of illustrating the general principles of the specification, and is not intended to limit the scope of the present disclosure. The scope of protection of the present disclosure is defined by the appended claims.
[0025] In order to facilitate the understanding of the embodiments of the present disclosure, the following will be further explained and described with specific examples combined with the accompanying drawings, and each drawing does not constitute a limitation to the embodiments of the present disclosure.
[0026] Figure 1 is a front structure schematic diagram of a golden finger clamp provided by an exemplary embodiment of the present disclosure, as shown in Figure 1 The clamp includes a clamp body 1, first and second fixed blocks 5 and 6 are respectively arranged on both sides of the clamp body 1, a first gap is formed between the clamp body 1 and the first fixed block 5, a second gap is formed between the clamp body 1 and the second fixed block 6, and the widths of the first and second gaps are adjustable.
[0027] In the embodiment, the adjustable gaps between the clamp body 1 and the first and second fixed blocks 5 and 6 enable the clamp to adapt to golden fingers of different thicknesses, without the need to prepare special clamps for golden fingers of different thicknesses, thereby reducing the requirement for equipment investment and storage space. The operator can quickly adjust the widths of the first and second gaps according to actual needs, thereby meeting the testing requirements of golden fingers of different thicknesses and improving work efficiency.
[0028] In another exemplary embodiment, long slot screw holes are arranged at corresponding positions of one side of the clamp body 1 and the first fixed block 5 and at corresponding positions of the other side of the clamp body 1 and the second fixed block 6.
[0029] In this embodiment, the long slot type screw hole is a non-circular hole design, which is longer from one end to the other end than a normal circular hole, forming an oval or linear segment shape. The long slot type screw hole allows the screw to have a range of movement in the length direction of the hole, rather than being fixed at a point like a standard circular bolt hole. The long slot type screw hole can provide a certain degree of position adjustment flexibility, so that when the clamp body 1 needs to cooperate with the first fixed block 5 or the second fixed block 6, even if there is a slight positional deviation or needs to adapt to different sizes of parts, the screw can still move in the hole to find the appropriate position. In terms of gold finger testing, by setting the long slot type screw hole, the first fixed block 5 and the second fixed block 6 can be appropriately displaced according to the actual thickness of the clamped gold finger, ensuring that no matter how the thickness of the gold finger changes, it can be firmly and correctly fixed by the clamp, not only improving the adaptability of the clamp, but also enhancing its versatility and practicality.
[0030] In another exemplary embodiment, the upper end surface of the clamp body 1 is symmetrically provided with a first boss 7 and a second boss 8 along the length direction of the clamp body 1, and a sliding groove is formed between the first boss 7 and the second boss 8.
[0031] In this embodiment, the first boss 7 and the second boss 8 are structurally identical, each including a first convex surface and a second convex surface. Taking the first boss 7 as an example, the first convex surface 7-1 and the second convex surface 7-2 of the first boss 7 are integrally connected and in a stepped shape. Figure 4 As shown in the figure, the bottom end of the gold finger is provided with a support table 15, which includes an upper end portion and a lower end portion, and the cross section of the upper end portion is wider than that of the lower end portion. Still taking the first boss 7 as an example, when the lower end portion of the support table 15 is firmly clamped by the clamp body 1 and the first fixed block 5, the upper end portion of the support table 15 is in line with the second convex surface 7-2 of the first boss 7, so that the upper end portion of the support table 15 can be embedded and clamped with the first boss 7, thereby ensuring that the gold finger is stably fixed in the first gap formed by the clamp body 1 and the first fixed block 5, avoiding unnecessary shaking.
[0032] Through the above design, the gold finger can maintain a stable position during testing, ensuring the accuracy and reliability of the test results. At the same time, due to the stepped design of the first boss 7 and the second boss 8, it can adapt to gold fingers of different thicknesses, increasing the application range and flexibility of the clamp.
[0033] In another exemplary embodiment, the clamp body 1 is symmetrically provided with a first height limiting block 2 and a second height limiting block 4 along the length direction of the clamp body 1.
[0034] In this embodiment, the first height-limiting block 2 and the second height-limiting block 4 can move up and down and front and back in the sliding groove formed between the first boss 7 and the second boss 8, thereby allowing the user to accurately adjust the height of the first height-limiting block 2 and the second height-limiting block 4 according to the actual thickness of the gold finger to be tested. This means that regardless of the size of the gold finger, by adjusting the position of the height-limiting block, it can be ensured that the gold finger is fixed in a position most suitable for testing. By accurately adjusting the first height-limiting block 2 and the second height-limiting block 4, it can be ensured that the pressure between the gold finger and the contact surface is consistent each time the test is performed, thereby improving the accuracy and repeatability of the test results. Further, by quickly adjusting the first height-limiting block 2 and the second height-limiting block 4, the time required to frequently replace or adjust the clamp due to changes in the thickness of the gold finger can be reduced, thereby improving the work efficiency of the clamp.
[0035] It should be noted that the design of the sliding groove not only supports the movement of the first height-limiting block 2 and the second height-limiting block 4, but also limits the displacement direction of the first height-limiting block 2 and the second height-limiting block 4 through its structure, ensuring that the first height-limiting block 2 and the second height-limiting block 4 can only move along a predetermined path. This can prevent unnecessary lateral displacement or tilting of the first height-limiting block 2 and the second height-limiting block 4 during testing, ensuring the accuracy of the gold finger fixing position. In addition, the presence of the sliding groove makes the installation and removal of the first height-limiting block 2 and the second height-limiting block 4 more convenient, reducing the operation steps and time cost. Further, when the first height-limiting block 2 and the second height-limiting block 4 need to be accurately calibrated, the limiting path provided by the sliding groove can serve as a reference, making it easier for the operator to adjust the first height-limiting block 2 and the second height-limiting block 4 to the correct position, thereby simplifying the calibration process.
[0036] In summary, the first height-limiting block 2 and the second height-limiting block 4 serve to provide a flexible, accurate and efficient mechanism to adapt to gold fingers of different thicknesses, while ensuring the consistency of the test conditions and the reliability of the test results.
[0037] In another exemplary embodiment, as shown in Figure 2 The bottom end of the clamp body 1 and the corresponding position of the first height-limiting block 2 are provided with a first jack hole 11 and a second jack hole 12, and the bottom end of the clamp body 1 and the corresponding position of the second height-limiting block 4 are provided with a third jack hole 13 and a fourth jack hole 14.
[0038] In this embodiment, the first top screw hole 11, the second top screw hole 12, the third top screw hole 13 and the fourth top screw hole 14 are provided with top screws, which can be used to finely adjust the up and down positions of the first height limiting block 2 and the second height limiting block 4. By tightening or loosening the top screws, the height of the first height limiting block 2 and the second height limiting block 4 can be finely adjusted to ensure that the first height limiting block 2 and the second height limiting block 4 reach the desired height.
[0039] In addition, as shown in the drawings, the opposite side of the first boss 7 and the second boss 8 is provided with a scale line. By providing a scale line, an operator can be provided with a visual reference, so that the position of the first height limiting block 2 and the second height limiting block 4 can be adjusted more accurately. By checking the scale line, the operator can adjust the first height limiting block 2 and the second height limiting block 4 to the desired accurate height, ensuring that the pressure between the gold finger and the contact surface is consistent each time the test is performed, thereby improving the accuracy of the test results. Figure 3 In addition, when it is necessary to record specific test conditions or trace back previous results, the specific values provided by the scale line can make these information more explicit. For example, if a problem occurs in a certain test batch, the problem can be analyzed by checking the scale value corresponding to the position of the height limiting block used at that time.
[0040] When the first height limiting block 2 and the second height limiting block 4 are adjusted to the appropriate position, the top screws can also provide stable support for the first height limiting block 2 and the second height limiting block 4, preventing unnecessary displacement of the first height limiting block 2 and the second height limiting block 4 during the test due to external forces, thereby ensuring the height consistency of the gold fingers fixed on both sides of the clamp and enhancing the reliability of the test.
[0041] In another exemplary embodiment, the clamp body is also provided with a screw hole 3, which is located at the central position of the sliding groove.
[0042] In this embodiment, the clamp body 1 is fixed to the handler through the screw hole 3. The position of the screw hole 3 ensures that the clamp can be accurately installed at the predetermined position on the handler, ensuring that the orientation of the clamp is consistent each time it is installed. This helps to maintain the consistency of the gold finger test conditions and reduces errors caused by different installation positions.
[0043] In another exemplary embodiment, the bottom end of the clamp body 1 is also provided with a first lock hole 9 and a second lock hole 10, the first lock hole 9 is located between the first top screw hole 11 and the second top screw hole 12, and the second lock hole 10 is located between the third top screw hole 13 and the fourth top screw hole 14.
[0044]
[0045] In this embodiment, the first locking hole 9 and the second locking hole 10 are used to lock the first height-limiting block 2 and the second height-limiting block 4, respectively. The first locking hole 9 and the second locking hole 10 provide an additional locking mechanism, so that the first height-limiting block 2 and the second height-limiting block 4 will not be displaced during the test, even if external forces or vibrations are encountered, ensuring that the gold finger always remains at the same height during the entire test, thereby improving the accuracy and reliability of the test results.
[0046] In addition, the first locking hole 9 is located between the first and second set screws, and the second locking hole 10 is located between the third and fourth set screws, which allows the height-limiting blocks to be fixed from multiple points, providing a more stable support structure. The mechanism of multi-point fixation can disperse stress and reduce the case of excessive stress on a single point, further ensuring the stability and durability of the clamp.
[0047] Further, when precise calibration of the first height-limiting block 2 and the second height-limiting block 4 is required, the height-limiting blocks can be easily moved by loosening the locking device in the locking hole, and then relocked after calibration. This design not only facilitates daily maintenance work, but also ensures that the first height-limiting block 2 and the second height-limiting block 4 can be accurately set to the required position each time the test is performed.
[0048] The above embodiments are only for illustrating the technical concepts and characteristics of the present disclosure, and the purpose is to enable those skilled in the art to understand the content of the present disclosure and implement it, and cannot limit the protection scope of the present disclosure. Any equivalent changes or modifications made in accordance with the spirit and essence of the present disclosure should be covered within the protection scope of the present disclosure.
