Description

Technical Field

[0001] This application relates to the field of circuit board testing technology, and in particular to a circuit board testing fixture. Background Technology

[0002] Circuit boards are an indispensable component of electronic devices, primarily used to achieve electrical connections between electronic components. Circuit boards can be configured in various forms, including single-sided, double-sided, and multilayer boards, to realize complex circuit designs. Single-sided boards have simpler wiring and are suitable for simple circuit designs; double-sided boards offer more wiring options and are suitable for more complex circuits; while multilayer boards, by increasing the number of wiring layers, provide greater design flexibility and higher complexity, and are often used in high-performance devices.

[0003] After production, existing circuit boards often require random sampling to ensure the pass rate. This necessitates the use of testing fixtures to inspect the circuit boards. However, existing testing fixtures still require manual assistance, which can lead to errors due to fatigue from prolonged manual operation. Therefore, the accuracy and efficiency of the testing process can be further improved. Utility Model Content

[0004] The purpose of this invention is to solve or at least alleviate the problem that existing testing equipment may still require some manual assistance in testing, thus the accuracy and efficiency of testing can be further improved.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a circuit board testing fixture, comprising a housing, a cover hinged to the top of the housing, a locking buckle on one side of both the housing and the cover, a bracket fixedly installed on the top outer wall of the cover, and a testing mechanism on the top of the cover;

[0006] The detection mechanism includes a positioning seat fixedly mounted on the cover, a circuit board mounted on the positioning seat, and a connection detection line for connecting the circuit board. A fixing frame is fixedly mounted on the bracket, and a mounting bracket is provided on one side of the fixing frame. A connecting arm is provided inside the mounting bracket, and a handle is fixedly mounted on the connecting arm. A push rod is provided inside the mounting bracket, and a threaded rod is fixedly connected to one end of the bottom of the push rod. A pressure plate is sleeved on the threaded rod, and two nuts are symmetrically screwed onto the threaded rod. Multiple positioning posts are fixedly mounted on the bottom outer wall of the pressure plate.

[0007] By adopting the above technical solution, the circuit board is placed on the positioning seat and connected. At this time, the handle can be pulled to rotate upward, which will drive the connecting arm to rotate and drive the push rod to move downward. The downward movement of the push rod will drive the pressure plate and multiple positioning columns to move downward, thereby positioning and installing the circuit board. The circuit board can then be inspected. Therefore, no manual auxiliary operation is required for inspection, which can further improve the accuracy and efficiency of inspection.

[0008] Optionally, a limiting sleeve is slidably provided on the push rod, and the limiting sleeve is fixedly installed on the fixed frame.

[0009] By adopting the above technical solution, the installation can be limited by setting a limiting sleeve.

[0010] Optionally, heat dissipation holes are provided on both outer walls of the housing, and filter screens are provided on both inner walls of the housing, with both filter screens located on the side of the corresponding heat dissipation hole.

[0011] By adopting the above technical solution, heat dissipation holes can be set to achieve cooling and heat dissipation, and the heat dissipation holes can also serve as handles.

[0012] Optionally, two elongated rods are symmetrically fixedly installed on the bracket, and each of the two elongated rods is slidably provided with a sliding sleeve, and the pressure plate is fixedly sleeved on the two sliding sleeves.

[0013] By adopting the above technical solution, the installation can be aided by setting up long poles.

[0014] Optionally, fan frames are provided on both inner walls of the housing, and a fan is provided in each of the two fan frames.

[0015] By adopting the above technical solution, a fan can be installed to cool and dissipate heat from the detection circuit inside the housing, thereby improving its service life.

[0016] Optionally, each of the two fan frames is fixedly mounted with a mounting ear, and each of the two mounting ears is screwed with a fixing bolt.

[0017] By adopting the above technical solution, the installation ears can be set up to assist in the installation process.

[0018] Optionally, two fixing posts are symmetrically fixedly installed on one inner wall of the housing. Each of the two fixing posts is slidably provided with a clamping plate. A rectangular plate is fixedly installed at one end of each of the two fixing posts. The two rectangular plates are fixedly installed inside the housing. A telescopic spring is sleeved on each of the two fixing posts. The two ends of the telescopic spring are respectively fixedly installed on the outer wall of the clamping plate and the rectangular plate on the side that are close to each other.

[0019] By adopting the above technical solution, an automatic reset function can be achieved by setting a telescopic spring.

[0020] Optionally, the same synchronizing rod is fixedly installed on one side of the outer wall of both clamping plates, and a pull rod is fixedly installed on one side of the outer wall of the synchronizing rod.

[0021] By adopting the above technical solution, pulling the lever moves the two synchronous rods, which in turn move the two synchronous rods. The movement of the two synchronous rods also moves the two clamping plates and compresses the corresponding telescopic springs. At this time, the positioning and installation of the filter screen will be released, so the filter screen can be disassembled, replaced, and cleaned and maintained, improving the convenience and flexibility of use.

[0022] In summary, the beneficial effects of this application are as follows:

[0023] 1. In this application, the circuit board is placed on the positioning seat and connected by the cooperation of the pressure plate and the like. At this time, the handle can be pulled to flip it upward, which will drive the connecting arm to rotate and drive the push rod to move downward. The downward movement of the push rod will drive the pressure plate and multiple positioning posts to move downward, thereby positioning and installing the circuit board. The circuit board can then be inspected. Therefore, no manual auxiliary operation is required for inspection, and the accuracy and efficiency of inspection can be further improved.

[0024] 2. In this application, the heat dissipation holes are used in conjunction with other features. By setting the heat dissipation holes, cooling can be achieved. The heat dissipation holes can also serve as handles. The filter screen can cover the heat dissipation holes, thereby preventing dust from entering the housing through the heat dissipation holes and protecting the detection circuit inside the housing. By setting the fan, the detection circuit inside the housing can be cooled and dissipated, thereby improving the service life. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] Please see Figure 1-3 A circuit board testing fixture includes a housing 1, a cover 2 hinged to the top of the housing 1, a latch 3 located on one side of the housing 1 and the cover 2 and cooperating with each other, the latch 3 serving to fix the installation and improve safety during use, a bracket 7 fixedly installed on the outer wall of the top of the cover 2, a testing mechanism located on the top of the cover 2, a heat dissipation mechanism located inside the housing 1, and a filtering mechanism. The testing mechanism eliminates the need for manual auxiliary operation and can further improve the accuracy and efficiency of testing. The filtering mechanism prevents dust from entering the housing 1 through the heat dissipation holes 5 and protects the testing circuit inside the housing 1.

[0032] The testing mechanism includes a positioning seat 8 fixedly mounted on the cover 2, a circuit board 9 mounted on the positioning seat 8, and a connection testing line for connecting the circuit board 9 on the positioning seat 8, a fixing frame 12 fixedly mounted on the bracket 7, a mounting frame 13 on one side of the fixing frame 12, a connecting arm 14 in the mounting frame 13, a handle 15 fixedly mounted on the connecting arm 14, a push rod 16 in the mounting frame 13, a threaded rod 18 fixedly mounted on one bottom end of the push rod 16, a pressure plate 10 sleeved on the threaded rod 18, two nuts 19 symmetrically screwed onto the threaded rod 18, multiple positioning posts 11 fixedly mounted on the bottom outer wall of the pressure plate 10, and a limiting sleeve 17 slidably mounted on the push rod 16, with the limiting sleeve 17 fixedly mounted on the fixing frame 12.

[0033] In use, the circuit board 9 is placed on the positioning seat 8 and connected. At this time, the handle 15 can be pulled upward to rotate and move, which will drive the connecting arm 14 to rotate and drive the push rod 16 to move downward. The downward movement of the push rod 16 will drive the pressure plate 10 and multiple positioning posts 11 to move downward, thereby positioning and installing the circuit board 9. The circuit board 9 can then be inspected, so no manual auxiliary operation is required for inspection, which can further improve the accuracy and efficiency of inspection. Pulling the handle 15 in the opposite direction will drive the pressure plate 10 to move upward, thereby completing the positioning and installation of the circuit board 9, avoiding the circuit board 9 from shifting or shaking during inspection, thus improving the accuracy of inspection.

[0034] Reference Figure 1-3 The heat dissipation mechanism includes two heat dissipation holes 5 on the outer walls of both sides of the housing 1, two filter screens 6 on the inner walls of both sides of the housing 1, and both filter screens 6 are located on one side of the corresponding heat dissipation hole 5. By setting the filter screens 6, the heat dissipation holes 5 can be blocked, thereby preventing dust from entering the housing 1 through the heat dissipation holes 5 and protecting the detection circuit inside the housing 1. Two long rods 20 are symmetrically fixedly installed on the bracket 7, and sliding sleeves 21 are slidably provided on both long rods 20. The pressure plate 10 is fixedly sleeved on the two sliding sleeves 21. Two fan frames 22 are set on the inner walls of both sides of the housing 1, and a fan 23 is provided in each of the two fan frames 22. Two mounting ears 24 are fixedly installed on the two fan frames 22, and two fixing bolts 25 are screwed onto the two mounting ears 24.

[0035] During use, the heat dissipation holes 5 are provided for cooling and heat dissipation, and the heat dissipation holes 5 also serve as handles. The filter screen 6 can cover the heat dissipation holes 5 to prevent dust from entering the housing 1 through the heat dissipation holes 5 and to protect the detection circuit inside the housing 1. The fan 23 is provided to cool and dissipate the detection circuit inside the housing 1, thereby improving its service life. By turning the two nuts 19 and turning them off, the positioning installation of the pressure plate 10 can be released, so that the pressure plate 10 can be disassembled and replaced, which facilitates the replacement of the pressure plate 10 with a suitable one, improving the convenience and flexibility of use.

[0036] Reference Figure 3-4The filtration mechanism includes two fixed columns 29 symmetrically fixedly installed on the inner wall of one side of the housing 1, and clamping plates 28 are slidably provided on both fixed columns 29; two rectangular plates 4 fixedly installed at one end of the two fixed columns 29, and both rectangular plates 4 are fixedly installed inside the housing 1; two telescopic springs 30 sleeved on the two fixed columns 29, and the two ends of the telescopic springs 30 are respectively fixedly installed on the outer wall of the clamping plate 28 and the rectangular plate 4 on the side close to each other; the same synchronizing rod 26 fixedly installed on the outer wall of one side of the two clamping plates 28; and a pull rod 27 fixedly installed on the outer wall of one side of the synchronizing rod 26.

[0037] In use, by opening the latch 3, the cover 2 can be opened, and then the pull rod 27 can be pulled. The movement of the pull rod 27 will drive the two synchronous rods 26 to move. The movement of the two synchronous rods 26 will also drive the two clamping plates 28 to move, and compress the corresponding telescopic springs 30. At this time, the positioning and installation of the filter screen 6 will be released, so the filter screen 6 can be disassembled, replaced and cleaned and maintained, improving the convenience and flexibility of use.

[0038] The implementation principle of this application is as follows: When in use, the circuit board 9 is first placed on the positioning seat 8 and connected. At this time, the handle 15 can be pulled to rotate upward, which will drive the connecting arm 14 to rotate and drive the push rod 16 to move downward. The push rod 16 moves downward, which will drive the pressure plate 10 and multiple positioning posts 11 to move downward, thereby positioning and installing the circuit board 9. At this time, the circuit board 9 can be tested. Therefore, no manual auxiliary operation is required for testing, and the accuracy and efficiency of testing can be further improved.

[0039] The heat dissipation holes 5 allow for cooling and also function as handles. The filter screen 6 covers the heat dissipation holes 5, preventing dust from entering the housing 1 and protecting the internal detection circuitry. The fan 23 further cools the internal detection circuitry, extending its lifespan. Opening the latch 3 opens the cover 2, allowing the pull rod 27 to move. This movement of the pull rod 27 moves the two synchronous rods 26, which in turn move the two clamping plates 28, compressing the corresponding telescopic springs 30. This releases the filter screen 6 from its mounting position, allowing for easy removal, replacement, and cleaning, improving convenience and flexibility. Rotating the two nuts 19 releases the pressure plate 10 from its mounting position, enabling its removal and replacement for a compatible alternative, further enhancing convenience and flexibility.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
