Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing fixture technology, and in particular to a flying wire testing fixture device. Background Technology
[0002] Flying wire test fixtures are commonly used testing tools in the electronics manufacturing industry. Their core components consist of probes, flying wires, adapter boards, and a fixing structure. They are primarily used for functional testing of semi-finished and finished products such as PCBs and electronic modules. Their function is to connect the fixture probes to the testing instrument via flying wires, precisely contacting the test points of the component under test. This allows for rapid detection of parameters such as circuit continuity, voltage, current, and signal transmission, identifying problems like short circuits, poor soldering, and component failures. This ensures compliance with product electrical performance standards, significantly improves testing efficiency and accuracy, and reduces human error.
[0003] In practical applications, existing flying wire testing fixtures, used in conjunction with clamps and multimeters, can meet the basic requirements for flying wire testing, but the following problems still exist: Common flying wire test fixtures, when used for withstand voltage testing, can only accommodate the spacing and test piece specifications of a single flying wire assembly due to the use of auxiliary clamps of specific sizes. When switching to different product models, it is necessary to first remove the old clamp, clean the fixture positioning reference surface, then install the new clamp and manually calibrate the alignment deviation between the flying wire probe and the test point. The process is cumbersome and affects work efficiency. Therefore, this application provides a flying wire test fixture to meet the requirements. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a flying wire testing fixture device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flying wire testing fixture device, comprising a support base, a withstand voltage tester and a mounting base disposed on the top of the support base, and further comprising: An adjustment assembly includes a first support frame disposed on the top of the mounting base, a sleeve disposed in the inner cavity of the first support frame, a knob connected to the side of the sleeve, a sliding rod disposed in the inner cavity of the sleeve, and a limit plate connected to the side of the sliding rod. An auxiliary component, the auxiliary component including a limiting groove formed on the top of the support base.
[0006] Furthermore, a first groove is formed on the outer surface of the sleeve, and a connecting plate is connected to one end of the sliding rod.
[0007] The technical effect of adopting the above technical solution is that by opening the first sliding groove, the protrusion can be made to translate when the sleeve rotates.
[0008] Furthermore, a protrusion is connected to the top of the connecting plate, one end of which extends into the inner cavity of the first sliding groove, and the one end of the protrusion is slidably connected to the inner cavity of the first sliding groove.
[0009] The technical effect of adopting the above technical solution is that by setting the protrusion, the first slide groove can drive the sliding rod to perform translational movement when the sleeve rotates.
[0010] Furthermore, a first support frame is fitted onto the outer surface of the sliding rod, and the bottom of the first support frame is fixedly connected to the top of the support base.
[0011] The technical effect of adopting the above technical solution is that by setting up the first support frame, the sliding rod can be supported.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: By setting a knob, the sleeve can be easily manually controlled to rotate. By setting the sleeve, the sliding rod can be driven to move the limit plate to translate. This allows the position of the fixed plate to be adjusted through the limit plate, effectively improving work efficiency when changing batches without disassembling and reinstalling the fixture.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a flying wire testing fixture device, including a support base 1, a withstand voltage tester 11 and a mounting base 12 disposed on the top of the support base 1, and further including: Adjustment component 2 includes a first support frame 26 disposed on the top of the mounting base 12, a sleeve 22 disposed in the inner cavity of the first support frame 26, a knob 21 connected to the side of the sleeve 22, a sliding rod 27 disposed in the inner cavity of the sleeve 22, and a limit plate 28 connected to the side of the sliding rod 27. Auxiliary component 3 includes a limiting groove 31 formed on the top of the support base 1, a first sliding groove 23 formed on the outer surface of the sleeve 22, a connecting plate 24 connected to one end of the sliding rod 27, a protrusion 25 connected to the top of the connecting plate 24, one end of the protrusion 25 extending into the inner cavity of the first sliding groove 23, and the protrusion 25 slidably connected to the inner cavity of the first sliding groove 23, a first support frame 26 sleeved on the outer surface of the sliding rod 27, the bottom of the first support frame 26 being fixedly connected to the top of the support base 1, and a limiting plate 28. The top of the sleeve 22 is provided with a guide groove 29, and a fixing plate 210 is slidably connected to the inner cavity of the guide groove 29. A rubber pad 211 is connected to the side of the fixing plate 210. A second support frame 212 is fitted on the outer surface of the sleeve 22. The guide groove 29 has a certain inclination angle to limit the position of the fixing plate 210. A pushing component is provided on the top of the mounting base 12 to limit one end of the flying needle element. In use, the sleeve 22 can be driven to rotate synchronously by manually rotating the knob 21 clockwise. During the rotation of the sleeve 22, the protrusion 25 moves along the inner cavity of the first groove 23 towards the end closer to the knob 21, thereby achieving the effect of synchronous movement of the sliding rod 27 driven by the connecting plate 24. During the movement of the sliding rod 27, the first support frame 26 fixedly connected to the top of the support base 1 can limit the movement trajectory of the sliding rod 27. When the sliding rod 27 moves, the distance between the fixed plates 210 can be shortened by the cooperation of the limiting plate 28 and the guide groove 29. Similarly, by rotating the knob 21 counterclockwise, the distance between the fixed plates 210 can be widened, thereby achieving the effect of quickly adapting to flying needle assemblies of different sizes and effectively improving the overall applicability. After the adjustment is completed, the flying needle to be tested is placed on the top of the limiting plate 28, and then the auxiliary push rod set on the top of the mounting base 12 is manually pushed to completely limit the position of the flying needle and prevent the flying needle from deviating when the pressure tester 11 performs a pressure test on the flying needle.
[0017] Furthermore, such as Figure 2 As shown: The top of the support base 1 is also provided with a second sliding groove 32. By the cooperation of the limiting groove 31 and the second sliding groove 32 on the top of the support base 1, the support of the fixing plate 210 can be improved, and the auxiliary guide groove 29 limits its position.
[0018] Working principle: like Figure 1-4 As shown: In use: First, manually rotate the knob 21 clockwise to drive the sleeve 22 to rotate synchronously. During the rotation of the sleeve 22, the protrusion 25 moves along the inner cavity of the first slide groove 23 towards the end closer to the knob 21, thereby achieving the effect of driving the sliding rod 27 to move synchronously through the connecting plate 24. When the sliding rod 27 moves, it can synchronously drive the limiting plate 28 and the guide groove 29 to move, thereby shortening the distance between the fixing plates 210. Similarly, by rotating the knob 21 counterclockwise, the distance between the fixing plates 210 can be widened, thereby achieving the effect of quickly adapting to flying needle assemblies of different sizes and effectively improving the overall applicability. After adjustment, place the flying needle to be tested on the top of the limiting plate 28, and then manually push the auxiliary push rod set on the top of the mounting base 12 to completely limit the position of the flying needle.
[0019] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
