Abstract
Description
Technical Field
[0001] This utility model relates to the field of tactile switch detection technology, and in particular to a tactile switch fault detector. Background Technology
[0002] In the field of modern electronic equipment manufacturing and repair, tactile switches are a commonly used electronic component, and their quality and reliability are of paramount importance. Tactile switch fault detectors are key equipment for ensuring the quality of tactile switches, widely used on production lines for quality control and for accurately diagnosing faulty switches during repair. However, current tactile switch fault detectors on the market have revealed numerous problems in practical use. Among these, the lack of effective protective measures for the control panel of the detector itself is a prominent pain point. During testing, operators are under high-intensity work conditions and highly focused on the testing process, but it is still difficult to avoid accidental touches of the control panel due to hand contact or excessively large operating movements. This leads to misdiagnosis of tactile switch faults, and incorrect test results disrupt the entire repair and production process, causing a series of chain reactions such as production stoppages and low repair efficiency.
[0003] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: when the switch tester body is performing the test, the operator may accidentally touch the control panel, which may change the test parameters, such as the test voltage and current threshold, causing the test results to deviate and leading to misjudgment of the tactile switch fault; therefore, a tactile switch fault tester is proposed to address the above problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing switch detectors, where operators may accidentally touch the control panel during testing, potentially altering testing parameters such as voltage and current thresholds, leading to deviations in test results and misjudgments of tactile switch malfunctions. Therefore, this invention proposes a tactile switch malfunction detector.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tactile switch fault detector, comprising a switch detector body, a control panel mounted on the surface of the switch detector body, three placement platforms mounted on the surface of the switch detector body, a protective device provided on the surface of the control panel, the protective device comprising two fixing plates, the two fixing plates being fixedly connected to the surface of the control panel, a rotating shaft being fixedly connected to one side of the two fixing plates that are close to each other, a protective cover being rotatably connected to the arc surface of the rotating shaft, an extension plate being fixedly connected to the bottom surface of the protective cover, a through hole being formed on the surface of the extension plate, a limiting plate being fixedly connected to the surface of the control panel, a fixing rod being slidably inserted into the limiting plate, a pull plate being fixedly connected to one end of the fixing rod, the fixing rod being slidably connected to the inner wall of the through hole in the extension plate, and the size of the fixing rod being adapted to the size of the through hole in the extension plate.
[0006] The effect achieved by the above-mentioned components is as follows: by setting up a protective device, the control panel of the switch tester body is protected during the testing process, preventing operators from accidentally touching it. This avoids the possibility that operators might accidentally touch the control panel during testing, which could change the testing parameters, such as the testing voltage and current threshold, causing deviations in the testing results and affecting the judgment of tactile switch faults. It could lead to a normal switch being judged as faulty, or vice versa, affecting subsequent maintenance and production processes.
[0007] Preferably, the arc surface of the rotating shaft is fitted with two torsion springs, and the two ends of the torsion springs are respectively fixedly connected to the protective cover and the fixing plate.
[0008] The aforementioned components achieve the following effect: under the action of the torsion spring, the protective cover can be quickly and automatically opened and fixed at a certain angle, thus improving the convenience of the device.
[0009] Preferably, the arc surface of the fixing rod is fitted with a spring, and the two ends of the spring are fixedly connected to the pull plate and the limiting plate, respectively.
[0010] The effect achieved by the above components is that, under the action of the spring, the fixing rod automatically springs back and inserts into the through hole of the extension plate, thereby improving the practicality of the device.
[0011] Preferably, a limiting rod is fixedly connected to one side of the extension plate, and the limiting rod is slidably connected to the surface of the control panel.
[0012] The effect achieved by the above components is that by setting the limiting rod, the protective cover is positioned so that the fixing rod can be inserted into the through hole of the extension plate in one go, thus avoiding the situation where the through hole of the extension plate and the fixing rod are not at the same horizontal position.
[0013] Preferably, the surface of the placement platform is provided with a clamping device, which includes six square plates. The six square plates are respectively fixedly connected to the surfaces of three placement platforms. A threaded rod is inserted into the internal thread of each square plate. A rotating plate is fixedly connected to one end of the threaded rod, and a stop plate is rotatably connected to the end of the threaded rod away from the rotating rod.
[0014] The effect achieved by the above-mentioned components is that by setting up a clamping device, the tactile switch is firmly clamped in the detection area of the placement stage, which prevents the tactile switch from moving, shaking or even falling off when it is being tested, thus affecting the normal progress of the test and keeping it stable during the test.
[0015] Preferably, a round rod is slidably inserted into the square plate, and one end of the round rod is fixedly connected to the abutment plate.
[0016] The effect achieved by the above components is that by setting the round rod, the movement state of the abutment is kept consistent, preventing the abutment from rotating along with the threaded rod when it rotates.
[0017] Preferably, an anti-slip pad is fixedly connected to the surface of the abutment, and the anti-slip pad is made of rubber.
[0018] The effect achieved by the above components is to increase the friction between the backing plate and the tactile switch by setting the anti-slip pad, thereby preventing the tactile switch from slipping during clamping.
[0019] In this invention, by setting up a protective device, the control panel of the switch tester is protected during the testing process, preventing accidental touch by the operator. This avoids the possibility that accidental touch of the control panel by the operator during testing may change the testing parameters, such as the testing voltage and current threshold, causing deviations in the testing results and affecting the judgment of tactile switch malfunctions. It may result in a normal switch being judged as faulty, or vice versa, affecting subsequent maintenance and production processes.
[0020] In this invention, by setting a clamping device, the tactile switch is firmly clamped in the detection area of the placement table, which avoids the tactile switch from moving, shaking or even falling off when it is being detected, thus affecting the normal progress of the detection and keeping it stable during the detection process.

[0027] Reference Figure 1 , Figure 2 and Figure 5 As shown, this utility model provides a technical solution: a tactile switch fault detector, including a switch detector body 1, a control panel 2 mounted on the surface of the switch detector body 1, three placement platforms 3 mounted on the surface of the switch detector body 1, and a protective device 4 on the surface of the control panel 2. By setting the protective device 4, the control panel 2 of the switch detector body 1 is protected during the detection process, preventing accidental touch by the operator. This avoids the possibility that accidental touch of the control panel 2 by the operator during the detection process may change the detection parameters, such as the detection voltage and current threshold, causing deviations in the detection results and affecting the judgment of tactile switch faults. It may mistake a normal switch for a fault, or vice versa, affecting subsequent maintenance and production processes. The surface of the placement platform 3 is provided with a clamping device 5. By setting the clamping device 5, the tactile switch is firmly clamped in the detection area of the placement platform 3, preventing the tactile switch from moving, shaking, or even falling off during the detection process, which would affect the normal progress of the detection and keep it stable during the detection process.
[0028] The specific design and function of its protective device 4 and clamping device 5 will be explained below.
[0029] Reference Figure 2 , Figure 3 and Figure 4As shown in this embodiment: the protective device 4 includes two fixed plates 401, which are fixedly connected to the surface of the control panel 2. A rotating shaft 402 is fixedly connected to one side of the two fixed plates 401 that is close to each other. A protective cover 403 is rotatably connected to the arc surface of the rotating shaft 402. An extension plate 405 is fixedly connected to the bottom surface of the protective cover 403. A through hole is opened on the surface of the extension plate 405. A limit plate 406 is fixedly connected to the surface of the control panel 2. A fixed rod 407 is slidably inserted into the limit plate 406. A pull plate 408 is fixedly connected to one end of the fixed rod 407. The fixed rod 407 is slidably connected to the inner wall of the through hole in the extension plate 405. The size of the fixed rod 407 is adapted to the size of the through hole in the extension plate 405. Two torsion springs 404 are sleeved on the arc surface of the rotating shaft 402. The two ends of the torsion springs 404 are respectively connected to the protective cover 403 and the fixed plate 401. The fixed connection, through the force of the torsion spring 404, achieves the effect of quickly and automatically opening and fixing the protective cover 403 at a certain angle, improving the convenience of the device. The arc surface of the fixing rod 407 is fitted with a spring 409, and the two ends of the spring 409 are fixedly connected to the pull plate 408 and the limiting plate 406 respectively. Through the force of the spring 409, the fixing rod 407 automatically springs back and inserts into the through hole of the extension plate 405, improving the practicality of the device. One side of the extension plate 405 is fixedly connected to a limiting rod 410, which slides with the surface of the control panel 2. By setting the limiting rod 410, the protective cover 403 is positioned, so that the fixing rod 407 can be inserted into the through hole of the extension plate 405 in one go, avoiding the situation where the through hole of the extension plate 405 and the fixing rod 407 are not at the same horizontal position.
[0030] Reference Figure 5 As shown, specifically, the clamping device 5 includes six square plates 51, which are fixedly connected to the surfaces of three placement platforms 3 respectively. Threaded rods 52 are threadedly inserted into the square plates 51. A rotating plate 53 is fixedly connected to one end of the threaded rod 52, and a stop plate 54 is rotatably connected to the end of the threaded rod 52 away from the rotating rod. A round rod 55 is slidably inserted into the square plates 51, and one end of the round rod 55 is fixedly connected to the stop plate 54. By setting the round rod 55, the movement state of the stop plate 54 is kept consistent, preventing the stop plate 54 from rotating along with the threaded rod 52 when it rotates. An anti-slip pad 56 is fixedly connected to the surface of the stop plate 54. The anti-slip pad 56 is made of rubber. By setting the anti-slip pad 56, the friction between the stop plate 54 and the tactile switch is increased, preventing the tactile switch from slipping during clamping.
[0031] Working principle: When the operator needs to protect the control panel 2 of the switch detector body 1, they move the protective cover 403, causing it to rotate on the arc surface of the rotating shaft 402. At this time, the torsion spring 404 will be in a torsional state, pulling the pull plate 408. The pull plate 408 drives the fixed rod 407 to slide within the limit plate 406. At this time, the spring 409 will be in a stretched state. Then, the protective cover 403 continues to rotate until the limit rod 410 touches the surface of the control panel 2 and stops. The pull plate 408 is then released, and the spring 409 releases its tensile force, driving the fixed rod 407 to slide within the limit plate 406. The fixed rod 407 automatically springs back into the through hole of the extension plate 405, completing the protection against accidental touch of the control panel 2. By setting the protective device 4, the control panel 2 of the switch tester body 1 is protected during the testing process, preventing accidental touch by the operator. This avoids the possibility that accidental touch of the control panel 2 by the operator during testing may change the testing parameters, such as the testing voltage and current threshold, causing deviations in the testing results and affecting the judgment of tactile switch faults. It may cause a normal switch to be judged as faulty, or vice versa, affecting subsequent maintenance and production processes.
[0032] When the operator needs to use the clamping device 5, the tactile switch is placed in the detection area of the placement table 3, and the rotating plate 53 is rotated. The rotating plate 53 drives the threaded rod 52 to rotate in the square plate 51. The threaded rod 52 will drive the abutment plate 54 to move towards the tactile switch. At this time, the round rod 55 will slide in the square plate 51 and move forward together with the abutment plate 54. The abutment plate 54 rotates with the rotation of the threaded rod 52 until the abutment plate 54 drives the anti-slip pad 56 to stop when it touches the tactile switch, thus completing the clamping of the tactile switch. By setting the clamping device 5, the tactile switch is firmly clamped in the detection area of the placement table 3, which avoids the tactile switch from moving, shaking or even falling off when it is being detected, which would affect the normal detection process and keep it stable during the detection process.
