Description

Technical Field

[0001] The utility model relates to the technical field of electric measuring jigs, in particular to an electric measuring jig with a long service life. Background Art

[0002] A touch screen, also known as a "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. When a graphic button on the screen is touched, the tactile feedback system on the screen can drive various connection devices according to a pre-programmed program. It can be used to replace mechanical button panels and create vivid audio and video effects through the LCD display.

[0003] In the touch screen manufacturing industry, functional testing is required before TP is shipped to ensure that the TP functions normally. Therefore, an electrical testing fixture is required for functional testing. When the electrical testing fixture is constantly putting in and taking out products for testing, it is easy to cause the edges of the glass positioning groove to wear and deform, resulting in poor positioning accuracy, which not only affects the functional test results, but also may require the replacement of the entire fixture, resulting in increased costs.

[0004] Therefore, in view of the technical problems mentioned above existing in the use of the electric measuring fixture in the prior art, we specifically designed an electric measuring fixture with a long service life. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0017] In the present application, through the designed installation groove, positioning strip one, positioning strip two, positioning strip three and glass positioning slot and other structures, multiple positioning strips form glass positioning slots at the installation groove, which is convenient for placing the product to be tested. At the same time, a segmented design is adopted, and multiple positioning strips are not fixedly connected to each other, so that any worn positioning strips can be replaced in a targeted manner, which can prevent the test product from directly contacting the side wall of the installation groove of the fixture table, thereby preventing the positioning edge of the installation groove from being worn and deformed after repeated use of the electrical testing fixture, resulting in poor positioning accuracy. At the same time, multiple positioning strips one, two and three can be prepared to achieve the purpose of replacement at any time. Not only can timely replacement be achieved to improve efficiency, but also the cost is lower than replacing the electrical testing fixture table. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Specifically, when any of the positioning strip 1 401 , the positioning strip 2 402 , and the positioning strip 3 403 is worn or damaged, the worn or damaged one can be replaced in a targeted manner, thereby increasing the service life of the entire fixture table 1 . The replacement method is simple and quick, and the fixture table 1 can be put into normal use as soon as possible.

[0027] See also Figure 1-3In this embodiment, three equidistant clamping strip through holes 6 are provided on the top of the first clamping strip 401, two equidistant clamping strip through holes 6 are provided on the top of the second clamping strip 402, and three equidistant clamping strip through holes 6 are provided on the top of the third clamping strip 403; threaded locking holes 7 are provided on the bottom wall of the installation groove 3 and at positions corresponding to each clamping strip through hole 6, and the first clamping strip 401, the second clamping strip 402 and the third clamping strip 403 are placed in the installation groove 3 and fastened by bolts.

[0028] Specifically, when the locking strip through holes 6 on the locking strip 1 401, the locking strip 2 402 and the locking strip 3 403 are aligned with the threaded locking holes 7 at the corresponding positions, bolts can be used to pass through the locking strip through holes 6 and screwed into the threaded locking holes 7, thereby fixing the locking strip 1 401, the locking strip 2 402 and the locking strip 3 403 to the mounting groove 3. At the same time, the bolts can be hexagon socket bolts, which can be easily turned and disassembled, thereby improving the replacement efficiency of the locking strip 1 401, the locking strip 2 402 and the locking strip 3 403.

The two third positioning strips 403 have the same length, so that the prepared positioning strip 403 can be taken out for installation at will when replacing. There will be no errors in installation caused by different lengths. The widths of the first positioning strip 401, the second positioning strip 402 and the third positioning strip 403 are all the same, which can ensure that the glass positioning groove 5 formed at the installation groove 3 is regular, so that it is convenient to put in the suitable product.

[0033] See also Figure 1 In this embodiment, the thickness of the first locking bar 401, the second locking bar 402 and the third locking bar 403 is the same as the depth of the installation groove 3, and the top is on the same horizontal line as the top of the fixture table 1.

[0034] Specifically, the tops of the first, second, and third positioning bars 401, 402, and 403 are on the same horizontal line as the top of the fixture table 1, thereby preventing the first, second, and third positioning bars 401, 402, and 403 from protruding from the installation slot 3, which is convenient for use and ensures regularity.

[0035] See also Figure 2-3 In this embodiment, the inner bottom wall of the glass clamping groove 5 is a smooth mirror structure, and the side of the clamping strip 1 401, the clamping strip 2 402 and the clamping strip 3 403 close to the center of the installation groove 3 and the side in contact with the inner side of the installation groove 3 are also smooth mirror structures.

[0036] Specifically, the contact surfaces of the products to be tested are designed to be smooth mirror structures, thereby avoiding scratches on the contact surfaces of the products and ensuring the quality of the products.

[0037] See also Figure 1 and Figure 4 In this embodiment, the two ends of the first locking strip 401 form a right angle structure with the contact parts of the two third locking strips 403, and the ends of the two second locking strips 402 that are away from each other also form a right angle structure with the contact parts of the two third locking strips 403.

[0038] Specifically, when the positions where the first locking strip 401, the second locking strip 402, and the third locking strip 403 contact each other all form a right-angle structure, they can effectively adapt to the right-angle side of the product, thereby achieving stable limiting.

[0039] See also Figure 3 In this embodiment, the first locking bar 401, the second locking bar 402 and the third locking bar 403 are all made of wear-resistant steel or wear-resistant ceramics.

[0040] Specifically, the first locking bar 401, the second locking bar 402 and the third locking bar 403 are all made of wear-resistant steel or wear-resistant ceramics, so as to improve their wear resistance and thus their service life, reduce the frequency of replacement, and thus reduce costs.

[0041] When using:

[0042] The staff can place the product to be tested in the glass clamping groove 5 formed by the clamping strip 1 401, the clamping strip 2 402 and the clamping strip 3 403 at the installation groove 3, so as to limit and stabilize the product to be tested by using the limiting structure formed by the clamping strip 1 401, the clamping strip 2 402 and the clamping strip 3 403 to avoid the problem of poor test accuracy caused by the shaking of the product. After multiple products are placed on the fixture table 1, the clamping strip 1 401, the clamping strip 2 402 and the clamping strip 3 403 are close to the square concave One side of the center of the groove 2 (i.e., the side in contact with the product) may be worn. At this time, the staff only needs to loosen the bolt in the clamping strip through hole 6 on the worn clamping strip 1 401 (clamping strip 2 402 or clamping strip 3 403) to remove the clamping strip 1 401 (clamping strip 2 402 or clamping strip 3 403), and then take the prepared clamping strip 1 401 (clamping strip 2 402 or clamping strip 3 403) and re-fix it in the installation groove 3 with bolts. The entire replacement process is simple to operate and efficient.
