Description

Technical Field

[0001] This utility model relates to the field of electronic testing, and more specifically, to an adapter fixture for bare wire testing. Background Technology

[0002] In the manufacturing and R&D of electronic products, bare wire testing is a crucial step. It is used to inspect the electrical properties of bare wires, such as resistance and insulation performance, to ensure that the wires meet product quality requirements. Currently, bare wire testing is typically performed manually by placing test probes into contact with the bare wire.

[0003] However, this approach has many problems:

[0004] Manual operation makes it difficult to ensure that the test probe maintains a stable and good contact with the bare wire at all times. During the test, even slight vibrations or unintentional touches by the operator may cause poor contact between the probe and the bare wire, thereby affecting the accuracy and reliability of the test results, and may even lead to misjudgment, classifying qualified products as unqualified products, or missing unqualified products during testing.

[0005] Manually connecting probes to bare wires one by one is a tedious and time-consuming process. Especially in large-scale production, where a large number of bare wires need to be tested, this inefficient testing method can seriously affect production schedules and increase production costs.

[0006] Therefore, we have made improvements to this by proposing an adapter fixture for bare wire testing. Utility Model Content

[0007] To address the shortcomings of existing technologies, this invention provides an adapter fixture for bare wire testing, which solves the problems mentioned in the background art.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] An adapter fixture for bare wire testing to address the aforementioned issues.

[0010] The application is as follows:

[0011] The device includes a base, a fixing block is fixedly installed on the upper surface of the base, and a bare wire positioning mechanism is provided above the fixing block. A fixing box is provided on one side of the upper surface of the base located on the fixing block, and a mounting plate is slidably connected to the upper side of the fixing box. Several test probes are installed on the side of the mounting plate facing the bare wire positioning mechanism, and a test device is installed on the upper surface of the mounting plate. A moving mechanism is provided between the mounting plate and the fixing box.

[0012] The bare wire positioning mechanism includes a rotating plate, which is rotatably connected to a fixed block. A groove is provided on one side surface of the rotating plate, and a rubber pad is fixedly connected inside the groove. Several placement grooves are provided on the upper surface of the fixed block and one side surface of the rubber pad. Several fixed cylinders are fixedly installed on one side surface of the fixed block located on one side of the placement groove.

[0013] As a preferred technical solution of this application, a mounting block is fixedly installed on one side surface of the rotating plate, and a mounting groove is opened on the upper side surface of one end of the fixed block, and the mounting block is engaged with the mounting groove.

[0014] As a preferred technical solution of this application, the mounting block has a sliding groove inside, and a baffle is slidably connected inside the sliding groove. A locking block is fixedly installed on one side surface of the baffle, and one side surface of the locking block is inclined. A spring is fixedly installed between the baffle and the inner wall of the sliding groove.

[0015] As a preferred technical solution of this application, a mounting hole is provided on one side surface of the mounting groove, and the locking block is engaged with the mounting hole.

[0016] As a preferred technical solution of this application, the moving mechanism includes a moving block, which is slidably connected inside the fixed box and fixedly connected to the lower surface of the mounting plate.

[0017] As a preferred technical solution of this application, a fixing plate is fixedly installed inside the fixing box, and a threaded rod is rotatably connected between one side of the surface of the fixing plate and the inner wall of the fixing box. One end of the moving block is threadedly connected to the threaded rod. A motor is fixedly installed on one side surface of the fixing plate, and the output end of the motor is fixedly connected to one end of the threaded rod.

[0018] As a preferred technical solution of this application, a limiting rod is fixedly installed between the other side of the surface of the fixing plate and the inner wall of the fixing box, and the other end of the moving block is slidably connected to the limiting rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In the scheme of this application:

[0021] 1. By setting up a bare wire positioning mechanism, utilizing the placement slots on the fixed block and rotating plate, as well as the fixing cylinder, the bare wire can be accurately and stably positioned and fixed. Simultaneously, the moving mechanism can precisely control the movement of the mounting plate, ensuring stable contact between the test probe and the bare wire. This effectively avoids poor contact problems caused by vibration or contact during manual operation, ensuring that the probe and bare wire maintain stable and good contact throughout the testing process, greatly improving the accuracy and reliability of test results and reducing the occurrence of misjudgments and missed detections.

[0022] 2. By setting up multiple placement slots and multiple test probes, operators only need to place multiple bare wires in the positioning mechanism, start the motor, and the moving mechanism will drive the mounting plate to move, so that the test probes automatically contact the bare wires and perform testing. The entire process does not require manual connection of each probe, making the operation simple and quick, significantly shortening the testing time. Especially in large-scale production, it can significantly improve production efficiency and effectively reduce production costs. Attached image description:

[0037] To address the technical problems in the background section, the following adapter fixture for bare wire testing is provided:

[0038] Combination Figure 1 - Figure 4 As shown, the present invention provides an adapter fixture for bare wire testing, comprising a base 1, a fixing block 2 fixedly mounted on the upper surface of the base 1, and a bare wire positioning mechanism 3 disposed above the fixing block 2. A fixing box 4 is disposed on one side of the upper surface of the base 1 located on the fixing block 2, and a mounting plate 5 is slidably connected to the upper side of the fixing box 4. Several test probes 6 are mounted on the side surface of the mounting plate 5 facing the bare wire positioning mechanism 3, and a test device 7 is mounted on the upper surface of the mounting plate 5. A moving mechanism 8 is disposed between the mounting plate 5 and the fixing box 4. The bare wire positioning mechanism 3 includes a rotating plate 301, and the rotating plate 301 is rotatably connected to the fixing block 2. A groove 302 is opened on one side surface of the rotating plate 301, and a rubber pad 303 is fixedly connected inside the groove 302. Several placement grooves 304 are opened on the upper surface of the fixing block 2 and one side surface of the rubber pad 303, and several fixing cylinders 305 are fixedly mounted on one side surface of the fixing block 2 located on the side of the placement groove 304.

[0039] In this embodiment: the base 1 serves as the basic support for the entire fixture. The fixing block 2 is installed on the upper surface of the base 1, and a bare wire positioning mechanism 3 is provided above it. The rotating plate 301 is rotatably connected to the fixing block 2, which facilitates the placement and removal of the bare wire. The rubber pad 303 in the groove 302 not only plays a buffering and protective role, but also increases the friction. Together with the placement groove 304 on the fixing block 2 and the rubber pad 303, as well as the fixing cylinder 305, it can position and fix bare wires of different specifications. When placing the bare wire, one end of the bare wire is placed into the fixing cylinder 305. The fixing box 4 located on one side of the fixing block 2 on the base 1 cooperates with the slidably connected mounting plate 5. The test probe 6 and the test device 7 installed on the mounting plate 5 are used to perform electrical performance tests on the bare wire. The moving mechanism 8 controls the movement of the mounting plate 5, so that the test probe 6 moves into the fixing cylinder 305 and makes stable contact with the bare wire, thereby efficiently completing the test.

[0040] In a preferred embodiment, a mounting block 306 is fixedly mounted on one side surface of the rotating plate 301, and a mounting groove 307 is provided on the upper side surface of one end of the fixed block 2, and the mounting block 306 is engaged with the mounting groove 307.

[0041] In this embodiment, the engagement of the mounting block 306 and the mounting groove 307 makes the connection between the rotating plate 301 and the fixed block 2 more stable and reliable. During the test, it can effectively prevent the rotating plate 301 from shaking or shifting due to external force or vibration, thereby ensuring that the bare wire is always in a precise positioning state, ensuring stable contact between the test probe 6 and the bare wire, and improving the accuracy of the test results. At the same time, the operation is simple. When it is necessary to place or remove the bare wire, simply operate the rotating plate 301 to separate or engage with the fixed block 2, which greatly improves the convenience and efficiency of the operation.

[0042] In a preferred embodiment, the mounting block 306 has a sliding groove 308 inside, and a baffle 309 is slidably connected inside the sliding groove 308. A locking block 310 is fixedly installed on one side surface of the baffle 309, and one side surface of the locking block 310 is inclined. A spring 311 is fixedly installed between the baffle 309 and the inner wall of the sliding groove 308.

[0043] In this embodiment, the baffle 309 can limit the locking block 310 to prevent it from sliding out. At the same time, the spring 311 can support and fix the locking block 310 by pressing against the baffle 309.

[0044] In a preferred embodiment, a mounting hole 312 is provided on one side surface of the mounting groove 307, and the locking block 310 is engaged with the mounting hole 312.

[0045] In this embodiment: when the rotating plate 301 engages with the mounting groove 307 of the fixed block 2 via the mounting block 306, as the mounting block 306 gradually goes deeper, the locking block 310 is squeezed by the side wall of the mounting groove 307 through its own inclined surface, slides in the slide groove 308 and compresses the spring 311 until the locking block 310 moves to the position of the mounting hole 312, the elastic force accumulated by the spring 311 is released instantly, pushing the baffle 309 to drive the locking block 310 to accurately engage in the mounting hole 312.

[0046] When it is necessary to disassemble the rotating plate 301, simply apply appropriate external force to disengage the locking block 310 from the mounting hole 312 to complete the disassembly. The operation is convenient and greatly improves the flexibility of use and maintenance efficiency of the entire adapter fixture.

[0047] In a preferred embodiment, the moving mechanism 8 includes a moving block 801, which is slidably connected inside the fixed box 4 and fixedly connected to the lower surface of the mounting plate 5.

[0048] In this embodiment: During the test, the smooth sliding of the drive moving block 801 within the fixed box 4 enables the mounting plate 5 to move synchronously and stably, ensuring that the test probe 6 can be inserted into the fixed cylinder 305 and achieve stable contact with a section of bare wire, thereby effectively ensuring the accuracy and reliability of the electrical performance test.

[0049] In a preferred embodiment, a fixing plate 802 is fixedly installed inside the fixing box 4, and a threaded rod 803 is rotatably connected between one side of the surface of the fixing plate 802 and the inner wall of the fixing box 4. One end of the moving block 801 is threadedly connected to the threaded rod 803. A motor 804 is fixedly installed on one side of the fixing plate 802, and the output end of the motor 804 is fixedly connected to one end of the threaded rod 803.

[0050] In this embodiment: when the motor 804 starts, it can drive the threaded rod 803 to rotate, thereby driving the moving block 801 to slide in the fixed box 4, realizing the movement of the mounting plate 5, ensuring that the test probe 6 can contact the bare wire, greatly improving the automation and accuracy of the test, and effectively improving the working efficiency and performance stability of the entire adapter fixture.

[0051] In a preferred embodiment, a limiting rod 805 is fixedly installed between the other side of the surface of the fixing plate 802 and the inner wall of the fixing box 4, and the other end of the moving block 801 is slidably connected to the limiting rod 805.

[0052] In this embodiment, the limiting rod 805 effectively prevents the moving block 801 from deflecting or shaking due to uneven force or other factors during movement, ensuring that the moving block 801 always moves smoothly along the predetermined straight trajectory, thereby ensuring the accuracy and stability of the movement of the mounting plate 5.

[0053] Specifically, the working principle of this solution is as follows:

[0054] When placing bare wires, operate the rotating plate 301 to place multiple bare wires in the placement grooves 304 on the surface of the fixed block 2, with one end inserted into the fixed cylinder 305. These placement grooves 304 are sized to accommodate bare wires of different specifications and can play a preliminary positioning role. Then, rotate the rotating plate 301, and the mounting block 306 on the rotating plate 301 will gradually approach the mounting groove 307 of the fixed block 2. As the mounting block 306 goes deeper into the mounting groove 307, the locking block 310 inside the mounting block 306 is squeezed by the side wall of the mounting groove 307, slides in the sliding groove 308 and compresses the spring 311. When the locking block 310 moves to the position of the mounting hole 312, the spring 311 releases its elasticity, pushing the locking block 310 into the mounting hole 312, so that the rotating plate 301 and the fixed block 2 are firmly connected, and the placement of the bare wires is completed.

[0055] During testing, the motor 804 is started, which drives the threaded rod 803 to rotate between the fixed plate 802 and the inner wall of the fixed box 4. The moving block 801, which is threadedly connected to the threaded rod 803, slides inside the fixed box 4. Because the other end of the moving block 801 is slidably connected to the limit rod 805, it can move smoothly in a straight line, thereby driving the mounting plate 5 to move, so that the test probe 6 is inserted into the fixed cylinder 305 and makes stable contact with the bare wire. The electrical performance of the bare wire is then tested by the test device 7.

[0056] After the test is completed, reverse the operation of motor 804 to reset mounting plate 5. When rotating rotating plate 301, apply external force to disengage the locking block 310 from mounting hole 312. This fixture, through the coordinated operation of its components, achieves precise positioning of bare wires, stable testing, and convenient operation, improving testing efficiency and accuracy.

[0057] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0058] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
