Description

Technical Field

[0001] This utility model relates to the field of electronic component technology, and more specifically to a tactile button self-locking switch for sensors. Background Technology

[0002] A self-locking tactile switch is a type of push-button switch. A typical tactile switch on the market includes a base, a plastic cover, a spring, a button, and six connecting terminals. The six terminals are located at one end of the base, arranged in two parallel rows, with three terminals in each row. Two terminals at either end are combined with the two terminals in the middle to form a group, thus defining the locked and released positions. A spring is fitted onto the button, and a spring hook is located at one end of the spring. A heart-shaped groove is formed in the plastic cover, with the two tips of the groove corresponding to the locked and released positions of the switch. Pressing the button deforms the spring towards the connecting terminals, and the spring hook slides along the heart-shaped groove to achieve the locked position, completing the circuit. Pressing the button again causes the spring hook to slide along the heart-shaped groove to achieve the released position, opening the circuit. This type of tactile switch has a relatively simple structure.

[0003] Tactile button self-locking switches can be designed with different electrical parameters and structural forms to adapt to different types of sensors. For example, the appropriate switch model can be selected according to the working voltage and current requirements of the sensor to ensure compatibility and stability with the sensor. However, when in use, the switch is easily triggered accidentally when people touch the button or when a foreign object hits the button, which will cause the sensor to shut down during use. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a tactile button self-locking switch for sensors.

[0005] This utility model provides the following technical solution: a tactile button self-locking switch for a sensor, comprising a base and six connecting terminals fixedly connected thereto. A switch cover is fixedly connected to the top of the base, and a button post is provided on the switch cover. One end of the button post penetrates through the top of the switch cover to the interior of the base and is slidably connected to the inner wall of the penetration point. A limiting body is fixedly connected to the bottom of the button post. A tension spring is sleeved on the outer wall of the button post, and the two ends of the tension spring are fixedly connected to the top of the limiting body and the bottom of the switch cover, respectively. A connecting spring for connecting the connecting terminals when necessary is fixedly connected to the bottom of the limiting body. A fixing mechanism for limiting the limiting body is provided inside the base. The fixing mechanism can pull and fix the limiting body when necessary, and when fixed, the fixing mechanism can reduce the probability of the button post being accidentally touched or impacted by foreign objects, thereby causing the sensor to be interrupted and shut down during use.

[0006] Furthermore, the fixing mechanism includes a connecting rod, one end of which is hinged to the inner wall of the base, and a magnetic locking rod is provided on the upper outer wall of the connecting rod. A V-shaped slot is formed on the outer wall of the limiting body, and a V-shaped locking plate is fixedly connected to the inner wall of the slot. The other end of the locking rod extends into the interior of the slot, and the inner walls of both ends of the slot are uniformly arc-shaped. A first magnet that can magnetically attract the locking rod is fixedly connected to the inner surface of the locking plate. A semi-circular first push block is fixedly connected to the outer wall of the locking plate, and a first baffle is fixedly connected to the inner wall of the slot. By setting the first push block, the first push block blocks the locking rod used to fix the limiting body, guiding it along the semi-circular arc surface of the first locking rod. This allows the locking rod to move slowly but not quickly within the slot, allowing the button post to be pressed gently and slowly, but preventing it from being pressed quickly due to impact or accidental contact. This reduces the probability of the sensor being interrupted and shut down during use due to accidental contact or impact from foreign objects.

[0007] Furthermore, a second magnet that can magnetically attract the lever is fixedly connected to the inner wall of the slot, and a semi-circular second push block is fixedly connected to the inner wall of the slot. A second baffle is fixedly connected to the outer surface of the card plate. By setting the semi-circular second push block, the lever can move slowly along the semi-circular arc surface of the second push block, but cannot move quickly in the slot. This allows the button post to be pressed slowly and gently, but it cannot be pressed quickly when it is hit or accidentally touched, thereby reducing the probability of the sensor being accidentally turned on when it is not working due to accidental touch or impact from foreign objects.

[0008] Furthermore, the two ends of the card plate are symmetrically arc-shaped; by making the two ends of the card plate arc-shaped, the probability of the card rod resetting and twisting at both ends of the card slot due to its own weight is reduced.

[0009] Furthermore, the locking rod is rotatably connected to the upper outer wall of the connecting rod; by allowing the locking rod to rotate, the locking rod can rotate due to the friction generated when in contact, thereby reducing the probability of wear between them.

[0010] Furthermore, the outer wall of the clamping rod is fitted with a rubber sleeve; by providing the rubber sleeve, the clamping rod does not directly contact the inner wall of the clamping groove and the surface of the clamping plate, thereby protecting the clamping rod.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model uses a fixing mechanism to pull and fix the limiting body when necessary. When fixing, the fixing mechanism can reduce the probability that the button post will be accidentally touched or hit by foreign objects, thus causing the sensor to be interrupted and shut down during use.

[0013] 2. This utility model allows the lever to move slowly along the semi-circular arc surface of the second push block, but it cannot move quickly within the slot. This allows the button post to be pressed slowly and gently, but it cannot be pressed quickly when it is hit or accidentally touched. This reduces the probability that the sensor will be accidentally turned on when it is not working due to accidental touch or impact from foreign objects. Attached Figure Description

Detailed Implementation

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Reference Figure 1-4This utility model provides a tactile button self-locking switch for a sensor, including a base 1 and six connecting terminals 2 fixedly connected thereto. A switch cover 3 is fixedly connected to the top of the base 1. A button post 4 is provided on the switch cover 3, and one end of the button post 4 penetrates through the top of the switch cover 3 to the interior of the base 1 and is slidably connected to the inner wall of the penetration point. A limiting body 5 is fixedly connected to the bottom of the button post 4. A tension spring 6 is sleeved on the outer wall of the button post 4, and the two ends of the tension spring 6 are fixedly connected to the top of the limiting body 5 and the bottom of the switch cover 3, respectively. A connecting spring 7 for connecting the connecting terminals 2 when necessary is fixedly connected to the bottom of the limiting body 5. A fixing mechanism for limiting the limiting body 5 is provided inside the base 1. The fixing mechanism can pull and fix the limiting body 5 when necessary, and when fixed, the fixing mechanism can reduce the probability of the button post 4 being accidentally touched or hit by foreign objects, thereby causing the sensor to be interrupted and shut down during use.

[0021] The fixing mechanism includes a connecting rod 8, one end of which is hinged to the inner wall of the base 1. A magnetic locking rod 9 is provided on the upper outer wall of the connecting rod 8. A V-shaped slot 10 is formed on the outer wall of the limiting body 5, and a V-shaped locking plate 11 is fixedly connected to the inner wall of the slot 10. The other end of the locking rod 9 extends into the interior of the slot 10. The inner walls of both ends of the slot 10 are uniformly arc-shaped. A first magnet 12, capable of magnetically attracting the locking rod 9, is fixedly connected to the inner surface of the locking plate 11. The outer wall of the locking plate 11 is fixedly connected to... A semi-circular first push block 13 is attached, and a first baffle 14 is fixedly connected to the inner wall of the slot 10. By setting the first push block 13, the first push block 13 blocks the locking rod 9 used to fix the limiting body 5, so that it is guided along the semi-circular arc surface of the first locking rod 9. This allows the locking rod 9 to move slowly, but not quickly within the slot 10. This allows the button post 4 to be pressed lightly and slowly, but it cannot be pressed quickly when it is hit or accidentally touched. This reduces the probability that the button post 4 will be accidentally touched or hit by foreign objects, thus causing the sensor to be interrupted and shut down during use.

[0022] The inner wall of the slot 10 is fixedly connected to a second magnet 15 that can magnetically attract the lever 9. The inner wall of the slot 10 is fixedly connected to a semi-circular second push block 16. The outer surface of the card plate 11 is fixedly connected to a second baffle 17. By setting the semi-circular second push block 16, the lever 9 can move slowly along the semi-circular arc surface of the second push block 16, but cannot move quickly in the slot 10. This allows the button post 4 to be pressed slowly and gently, but it cannot be pressed quickly when it is hit or accidentally touched. This reduces the probability of the button post 4 being accidentally touched or hit by foreign objects, thus reducing the probability of the sensor being accidentally turned on when it is not working.

[0023] The two ends of the card plate 11 are symmetrically arc-shaped. By making the two ends of the card plate 11 arc-shaped, the probability of the card rod 9 resetting and twisting at both ends of the card slot 10 due to its own weight is reduced.

[0024] The locking rod 9 is rotatably connected to the upper outer wall of the connecting rod 8; by allowing the locking rod 9 to rotate, the locking rod 9 can rotate due to the friction generated when in contact, thereby reducing the probability of wear between them.

[0025] The outer wall of the locking rod 9 is fitted with a rubber sleeve 18. By setting the rubber sleeve 18, the locking rod 9 does not directly contact the inner wall of the slot 10 and the surface of the locking plate 11, thereby protecting the locking rod 9.

[0026] The working principle of this utility model:

[0027] In use, gently press the button post 4 downwards. As the button post 4 moves downwards, it causes the limiting body 5 to move downwards as well. The movement of the limiting body 5 causes its inner wall to push against the locking rod 9, which is fitted with a rubber sleeve 18. Because the locking rod 9 is rotatably connected to the connecting rod 8, which is hinged to the inner wall of the base 1, the locking rod 9 can not only twist but also rotate on its own. The second magnet 15 attracts the locking rod 9, causing it to move along one side of the inner wall of the slot 10. As the locking rod 9 moves slowly, it can move along the semi-circular arc surface of the second push block 16 after contacting it, and then, under its own gravity... It then re-contacts the inner wall of the slot 10 and passes the bottom of the second baffle 17. It should be noted that when the button post 4 is accidentally touched or hit by a foreign object and moves rapidly downward, the lever 9 also moves rapidly inside the slot 10. When it moves rapidly and contacts the semi-circular arc surface of the second push block 16, it will be bounced up by the second push block 16 due to inertia, thus contacting the second baffle 17 and being blocked by it. After the button post 4 loses the pressing pressure, the tension spring 6 pulls the limiting body 5, thereby causing the lever 9 to reset and move, thus reducing the probability of the sensor being accidentally turned on when it is not necessary to work due to accidental touch or impact of a foreign object on the button post 4.

[0028] After the lever 9 passes the bottom of the second baffle 17, as it continues to move, it will be guided by the arc-shaped inner wall of the end of the slot 10 to move towards the upper part of the plate 11. Similarly, at this time, the tension spring 6 of the button post 4 is released to pull the limiting body 5, thereby causing the lever 9 to move towards the middle of the plate 11 and be locked by the plate 11. This causes the limiting body 5 to move, which in turn causes the connecting spring 7 to move, and then the connecting spring 7 to descend and connect to the connecting terminal 2, opening the circuit and locking it.

[0029] Similarly, when the circuit needs to be turned off, by pressing the button post 4 again, the lever 9 is attracted by the first magnet 12, and the first push block 13 and the first baffle 14 reduce the probability of the button post 4 being accidentally touched or hit by foreign objects, thereby causing the sensor to be interrupted and turned off during use.
