Technical Field

[0001] This utility model relates to a testing device, specifically a switch button testing device, belonging to the field of switch detection technology. Background Technology

[0002] A switch is an electronic component that can open a circuit, interrupt current, or direct current to another circuit. Wall switches are commonly used in homes and factories to control the on / off state of circuits. A wall switch is an electrical switch installed on a wall to connect and disconnect circuits, such as a switch for controlling lighting. During manufacturing, in order to test the durability of switches, samples are usually taken for pressure durability testing.

[0003] In the prior art, such as the switch button pressing durability testing device disclosed in announcement number CN216746718U, the left toothed plate and the moving plate are driven downward by gears, so that the left contact head presses the other side of the switch button, thus improving the advantage of cyclic testing of the switch. However, the above-mentioned prior art has the following shortcomings: When the above-mentioned durability testing device is used, when the switch is placed on the pad for testing, there is no limiting structure. During the pressing test, the switch button is prone to displacement or shaking due to the pressing force, causing the pressing position to deviate from the center of the button. It may also cause unnecessary damage to the switch button due to uneven force, reducing the reliability and stability of the test and causing many inconveniences to production testing. Utility Model Content

[0004] The purpose of this invention is to provide a switch button testing device to solve the problem that the above-mentioned device lacks a limiting structure, and the switch button is prone to displacement or shaking due to the pressure applied during the pressing test, which reduces the reliability and stability of the test and brings many inconveniences to production and testing.

[0005] The present invention achieves the above objectives through the following technical solution: a switch button testing device, comprising a substrate, a U-shaped frame mounted on the surface of the substrate, and a testing unit mounted inside the U-shaped frame for testing button pressing.

[0006] The surface of the substrate is provided with a sliding plate for supporting the switch to be tested. The surface of the sliding plate is provided with a switch adapter groove that is adapted to the size of the switch to be tested. During testing, the switch to be tested is placed in the switch adapter groove for initial positioning.

[0007] Depending on the size of the switch, the size of the switch adapter slot on the surface of the sliding plate is different, and the surface of the sliding plate is provided with a snap-fit ​​slot for picking up the switch, which is connected to the switch adapter slot.

[0008] As a further embodiment of this utility model: a sliding plate adapter groove adapted to the sliding plate is formed on the surface of the substrate, a limiting guide strip is fixedly installed on the inner side wall of the sliding plate adapter groove, a limiting guide groove adapted to the limiting guide strip is formed on the surface of the sliding plate, and the sliding plate is slidably connected to the sliding plate adapter groove formed on the surface of the substrate through the limiting guide strip and the limiting guide groove.

[0009] As a further improvement of this utility model: a strip groove is provided on the surface of the U-shaped frame, a fixed slide rod is installed in the strip groove, a connecting slide plate is slidably connected to the surface of the fixed slide rod, and a limiting pressure plate for secondary limiting of the switch is fixedly installed at one end of the connecting slide plate.

[0010] As a further improvement of this utility model: when the sliding plate carrying the switch slides into the sliding plate adapter groove, the limiting pressure plate presses against the surface of the switch to limit the switch again.

[0011] As a further improvement of this utility model: a second spring is installed on the surface of the fixed slide rod. The second spring is used to apply pressure to the connecting slide plate, so that the limiting pressure plate is tightly pressed against the surface of the switch.

[0012] As a further improvement of this utility model: one end of the limiting pressure plate is wedge-shaped, and the wedge-shaped end of the limiting pressure plate is used to slide into the surface of the switch when the limiting pressure plate initially contacts the switch.

[0013] As a further embodiment of this utility model: a U-shaped hand-held lever is fixedly installed on one side surface of the sliding plate, and a T-shaped limiting rod is slidably arranged inside the U-shaped hand-held lever. The T-shaped limiting rod passes through one end of the sliding plate and is inserted into the positioning hole opened on the surface of the substrate.

[0014] As a further improvement of this utility model: a telescopic sleeve is fixed to the surface of the T-shaped limiting rod, and the other end of the telescopic sleeve is installed on the top and bottom surface of the U-shaped hand-held pull rod. A spring is sleeved on the surface of the telescopic sleeve.

[0015] The beneficial effects of this utility model are:

[0016] This utility model, by setting a sliding plate with adaptable slots for switches of different sizes, can meet the testing needs of multiple sets of switches of different sizes, eliminating the need to configure separate testing equipment for each specification of switch, thus greatly reducing equipment investment costs. At the same time, the limiting pressure plate achieves position adjustment by sliding on a fixed slide rod through a connecting slide plate. Combined with the wedge-shaped end design, it can adapt to switches of various thicknesses, further expanding the applicability of the device and making it flexible for use in diverse switch testing scenarios.

[0017] Employing a dual limiting structure, the switch is initially positioned via the switch adapter slot to prevent lateral displacement. After the sliding plate slides into the base plate, the limiting pressure plate, under the action of spring two, tightly presses against the switch surface, forming a secondary reinforcement. This effectively prevents the switch from shifting or shaking due to force during the press test. In addition, the sliding plate achieves stable sliding through the cooperation of the limiting guide strip and the guide groove. The T-shaped limiting rod, together with spring one, ensures that the sliding plate is firmly fixed. The multiple structures work together to ensure the stability of the test environment, making the pressing position accurate and the test data reliable.

[0018] The slotted design facilitates quick and easy switch placement and removal, while the U-shaped hand lever allows for easy pushing and pulling of the sliding plate, reducing the time cost of switch installation and removal. The T-shaped limit rod automatically inserts into the positioning hole for fixation under the action of a spring, and can also quickly reset with the help of spring force when pulled out, simplifying the fixing and unlocking process of the sliding plate. The wedge-shaped end design of the limit pressure plate allows the sliding plate to automatically complete the limit without manual adjustment when sliding in. The overall structural design conforms to operating habits, significantly reducing the intensity of manual intervention and improving the work efficiency of batch testing.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] Example 1

[0028] like Figures 1 to 6 As shown, a switch button testing device includes a substrate 1, a U-shaped frame 2 mounted on the surface of the substrate 1, and a test unit 3 mounted in the U-shaped frame 2 for testing button pressing.

[0029] The surface of the substrate 1 is provided with a sliding plate 4 for supporting the switch to be tested. The surface of the sliding plate 4 is provided with a switch adapter groove 5 that is adapted to the size of the switch to be tested. During testing, the switch to be tested is placed in the switch adapter groove 5 for initial positioning.

[0030] Depending on the size of the switch, the size of the switch adapter groove 5 opened on the surface of the sliding plate 4 is different, and the surface of the sliding plate 4 is provided with a latching groove 10 for taking out the switch, and the latching groove 10 is connected to the switch adapter groove 5.

[0031] The sliding plate 4 is used to support the switch under test, enabling convenient movement and positioning of the switch during the testing process. The switch adapter slot 5 is adapted to the size of the switch under test, which can initially limit the switch and effectively prevent the switch from lateral displacement on the sliding plate 4, ensuring the positional stability of the switch before testing and laying the foundation for accurate subsequent testing. Different sizes of switch adapter slots 5 are set according to different sizes of switches, which greatly improves the versatility of the device, enabling the device to adapt to the testing needs of various specifications of switches and expanding the application range of the device. The snap-fit ​​slot 10 is connected to the switch adapter slot 5, which makes it convenient for operators to pick up and drop the switch before and after testing, improving the convenience of operation and saving operation time.

[0032] Furthermore, a sliding plate adapter groove 6 adapted to the sliding plate 4 is formed on the surface of the substrate 1. A limiting guide strip 7 is fixedly installed on the inner side wall of the sliding plate adapter groove 6. A limiting guide groove 8 adapted to the limiting guide strip 7 is formed on the surface of the sliding plate 4. The sliding plate 4 is slidably connected to the sliding plate adapter groove 6 formed on the surface of the substrate 1 through the limiting guide strip 7 and the limiting guide groove 8.

[0033] The sliding plate adapter groove 6 on the surface of the substrate 1, the limiting guide strip 7 on the inner sidewall, and the limiting guide groove 8 on the surface of the sliding plate 4 cooperate with each other to allow the sliding plate 4 to slide in the sliding plate adapter groove 6. This structure guides the movement of the sliding plate 4, ensuring that the sliding plate 4 can slide smoothly in or out along a fixed trajectory, avoiding deviation and jamming during the sliding process. On the other hand, the cooperation of the limiting guide strip 7 and the limiting guide groove 8 further enhances the connection stability of the sliding plate 4 on the substrate 1, preventing the sliding plate 4 from shaking during the test and ensuring the stability of the test environment.

[0034] Furthermore, the surface of the U-shaped frame 2 is provided with a strip groove 15, a fixed slide rod 18 is installed in the strip groove 15, a connecting slide plate 17 is slidably connected to the surface of the fixed slide rod 18, and a limit pressure plate 19 for secondary limit of the switch is fixedly installed at one end of the connecting slide plate 17.

[0035] The strip groove 15 on the surface of the U-shaped frame 2 provides an installation position for the fixed slide bar 18. The fixed slide bar 18 provides support and guidance for the sliding of the connecting slide plate 17. The limiting pressure plate 19 at one end of the connecting slide plate 17 can perform secondary limiting on the switch, ensuring effective limiting of the switch and further improving the stability of the switch during the test process.

[0036] Furthermore, when the sliding plate 4 carrying the switch slides into the sliding plate adapter groove 6, the limiting pressure plate 19 presses against the surface of the switch to limit the switch again.

[0037] When the sliding plate 4 carrying the switch slides into the sliding plate adapter groove 6, the limiting pressure plate 19 presses against the switch surface to limit the switch again. Through the double limiting method, the stability of the switch during the test is greatly enhanced, effectively preventing the switch from being displaced or shaking due to the pressing action of the test unit 3, ensuring the accuracy of the pressing test and ensuring the reliability of the test data.

[0038] Example 2

[0039] Improvements based on Example 1:

[0040] Furthermore, a second spring 16 is installed on the surface of the fixed slide bar 18. The second spring 16 is used to apply pressure to the connecting slide plate 17, causing the limiting pressure plate 19 to press tightly against the surface of the switch.

[0041] The elastic force of spring 16 keeps the pressure of the limit plate 19 on the switch stable, avoiding limit failure due to insufficient pressure and providing a continuous and stable limit function for the switch.

[0042] Furthermore, one end of the limiting pressure plate 19 is wedge-shaped, and the wedge-shaped end of the limiting pressure plate 19 is used to slide into the surface of the switch when the limiting pressure plate 19 initially contacts the switch.

[0043] When the limiting plate 19 initially contacts the switch, it guides the limiting plate 19 to slide smoothly onto the switch surface, avoiding jamming and collision during initial contact and reducing damage to the switch. At the same time, the wedge-shaped end design allows the limiting plate 19 to cooperate more smoothly with switches of different heights, improving the adaptability of the device and the smoothness of operation.

[0044] Furthermore, a U-shaped hand-held lever 11 is fixedly installed on one side surface of the sliding plate 4, and a T-shaped limiting rod 12 is slidably disposed inside the U-shaped hand-held lever 11. The T-shaped limiting rod 12 passes through one end of the sliding plate 4 and is inserted into the positioning hole 9 opened on the surface of the substrate 1.

[0045] The U-shaped hand lever 11 on one side of the sliding plate 4 makes it easy for operators to hold and move the sliding plate 4, improving the convenience of operation. The T-shaped limiting rod 12, which is slidably set inside the U-shaped hand lever 11, passes through the sliding plate 4 and is inserted into the positioning hole 9 of the substrate 1. This can firmly fix the sliding plate 4 on the substrate 1, prevent the sliding plate 4 from moving during the test, ensure the positional stability of the sliding plate 4 during the test, and provide a guarantee for the smooth progress of the test.

[0046] Furthermore, a telescopic sleeve 13 is fixed to the surface of the T-shaped limiting rod 12, and the other end of the telescopic sleeve 13 is installed on the top and bottom surface of the U-shaped hand-held pull rod 11. A spring 14 is sleeved on the surface of the telescopic sleeve 13.

[0047] The telescopic sleeve 13 also serves to limit the spring 14, preventing it from shifting during telescopic movement. The spring 14 fitted on the surface of the telescopic sleeve 13 provides elasticity to the T-shaped limiting rod 12, allowing it to be tightly inserted into the positioning hole 9, ensuring the fixation of the sliding plate 4. At the same time, when the T-shaped limiting rod 12 needs to be pulled out, the elasticity of the spring 14 facilitates its reset, improving the ease of operation.

[0048] It should be noted that the test unit 3 mentioned in the article is based on the same principle as the test device in "A Switch Button Press Durability Testing Device Disclosed in Announcement No. CN216746718U", and belongs to the prior art, so it will not be elaborated here.

[0049] Working principle: During the test preparation stage, the operator selects a sliding plate 4 with a correspondingly sized switch adapter slot 5 on its surface, based on the size of the switch to be tested. The switch to be tested is placed into the switch adapter slot 5, and the contour of the switch adapter slot 5 is used to initially limit the switch, preventing the switch from lateral displacement on the sliding plate 4. If it is necessary to remove the switch, it can be easily operated through the latching groove 10 that penetrates the switch adapter slot 5.

[0050] Subsequently, the operator holds the U-shaped hand lever 11 on one side of the sliding plate 4 and aligns the sliding plate 4 with the slide plate adapter groove 6 opened on the surface of the substrate 1. The limiting guide strip 7 on the inner side wall of the slide plate adapter groove 6 cooperates with the limiting guide groove 8 on the surface of the sliding plate 4, so that the sliding plate 4 slides smoothly into the slide plate adapter groove 6. During the sliding process, the sliding plate 4 will gradually approach the U-shaped frame 2. At this time, the limiting pressure plate 19 on the U-shaped frame 2, due to its wedge-shaped end design, can smoothly slide into the switch surface when it initially contacts the switch. As the sliding plate 4 continues to move, the connecting slide plate 17 slides on the fixed slide rod 18. The second spring 16 on the surface of the fixed slide rod 18 is compressed. The second spring 16 applies pressure to the connecting slide plate 17, causing the limiting pressure plate 19 to press tightly against the switch surface, realizing the secondary limiting of the switch and further enhancing the stability of the switch.

[0051] When the sliding plate 4 is fully slid into the slide plate adapter groove 6, the T-shaped limiting rod 12, under the elastic force of the spring 14, inserts one end of the rod through the sliding plate 4 into the positioning hole 9 on the surface of the substrate 1. At the same time, the telescopic sleeve 13 extends and retracts accordingly, firmly fixing the sliding plate 4 on the substrate 1 to prevent the sliding plate 4 from moving during the test.

[0052] After the switch is fixed, the test unit 3 is started. Under the control of the control component, the test unit 3 performs a reciprocating pressing test on the switch button. After the test is completed, the operator pulls the T-shaped limit plug 12 to pull it out of the positioning hole 9. The spring 14 is stretched, and then the sliding plate 4 is pulled out of the sliding plate adapter slot 6 through the U-shaped hand lever 11. The tested switch can then be taken out.

[0053] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0054] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
