Abstract
Description
Technical Field
[0001] This utility model relates to the field of tactile switches, specifically a tactile switch with good protection. Background Technology
[0002] A tactile switch is an electronic switch belonging to the category of electronic components. When in use, pressure is applied in the direction of operation to close the switch and connect the circuit. When the pressure is released, the switch opens. Its internal structure relies on the change of force on a metal spring to achieve the switching function. Tactile switches have advantages such as low contact resistance, precise operating force error, and diverse specifications. With the rapid development of electronic technology, the functions of electronic devices are becoming increasingly complex, and the requirements for the performance and reliability of tactile switches are also becoming higher and higher.
[0003] Most tactile switches on the market have a relatively simple structural design, with the button directly exposed and lacking a dedicated anti-accidental touch structure. While this fully utilizes the sensitivity of the tactile switch, it also brings obvious drawbacks. In daily use, because tactile switches are quite sensitive to pressing actions, even slight touches by the user, such as unintentional scratching or shaking of the switch by a finger or other object, may trigger the button and cause changes in the circuit state. Therefore, a tactile switch with better protection is proposed to address the above situation. Utility Model Content
[0004] To address the problem that existing tactile switches are highly sensitive and prone to accidental touches that alter the circuit state, this invention proposes a tactile switch with improved protection.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a tactile switch with good protection, including a tactile switch body, a button is provided on the tactile switch body, a fixing ring is detachably installed on the outer wall of the button, and a limit plate is rotatably connected to the fixing ring.
[0006] The top of the tactile switch body is provided with a limiting seat, the outer surface of the limiting seat is provided with a limiting groove, the top surface of the inner wall of the limiting groove is provided with an assembly groove, a contact block is slidably fitted on the assembly groove, the bottom of the contact block protrudes out of the assembly groove, a spring is fixed on the top surface of the inner wall of the assembly groove, and the bottom of the spring is fixed to the top of the contact block.
[0007] When the limiting plate rotates into the limiting groove, the outer wall of the limiting plate contacts the side wall of the abutment block.
[0008] Preferably, a rotating ring is rotatably fitted on the fixed ring, and a limit plate is fixedly connected to the outer wall of the rotating ring.
[0009] Preferably, the outer wall of the button is provided with an external thread, and the inner wall of the retaining ring is provided with an internal thread. When the retaining ring is installed on the button, the external thread and the internal thread are threadedly engaged.
[0010] Preferably, the outer wall of the fixed ring is provided with an annular mounting groove, and the rotating ring is rotatably engaged with the annular mounting groove.
[0011] Preferably, when the limiting plate rotates into the limiting groove, the top and bottom of the limiting plate contact the top surface of the limiting groove and the ground, respectively.
[0012] Preferably, the inner wall of the assembly groove is provided with sliding grooves on both sides.
[0013] Preferably, the abutting block includes a rectangular block, with sliders fixed on both sides of the rectangular block. The sliders slide in conjunction with the grooves, and a trapezoidal block is fixed at the bottom of the rectangular block. The trapezoidal block is an isosceles trapezoid.
[0014] Preferably, wear-resistant pads are provided on the inclined surfaces of the trapezoidal blocks.
[0015] The advantages of this utility model are:
[0016] 1. This utility model, through the structural design of a fixed ring, a rotating ring, a limiting plate, a limiting seat, and a contact block, allows the limiting plate to engage with the limiting groove during use. When the button is accidentally pressed downwards, it is limited by the limiting plate, which can prevent accidental pressing. At the same time, the limiting block ensures that the limiting plate can only be released when the user applies a specific direction and force, thereby enhancing the stability of the limiting plate during use, greatly reducing the probability of accidental pressing, and ensuring the stable operation of the equipment under unexpected operation.
[0017] 2. This utility model uses a detachable connection between the fixing ring and the button. When the limit plate is damaged due to improper operation during use, it can be easily removed from the button for individual replacement, reducing maintenance costs and time costs.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model.
[0027] The following is in conjunction with the appendix Figure 1 —6 provides further detailed information about this application.
[0028] This application discloses a tactile switch with good protection. (Refer to...) Figure 1 - Figure 6 A tactile switch with good protection includes a tactile switch body 1. The outer shell of the tactile switch body 1 is usually made of high-strength, well-insulated engineering plastic material, such as polycarbonate (PC), which can effectively prevent external environment from interfering with and damaging the internal circuit, and ensure the stable electrical performance of the switch. The surface of the outer shell can be frosted or anti-slip to facilitate operation during installation and use. A button 100 is provided on the tactile switch body 1. A fixing ring 2 is detachably installed on the outer wall of the button 100. A limit plate 4 is rotatably connected to the fixing ring 2.
[0029] The top of the tactile switch body 1 is fixed with a limit seat 5 by bolts. A limit groove 500 is opened on the outer surface of the limit seat 5. An assembly groove 501 is opened on the top surface of the inner wall of the limit groove 500. An abutment block 6 is slidably fitted on the assembly groove 501. The bottom of the abutment block 6 protrudes out of the assembly groove 501. A spring 7 is fixed on the top surface of the inner wall of the assembly groove 501. The bottom of the spring 7 is fixed to the top of the abutment block 6.
[0030] When the limiting plate 4 rotates into the limiting groove 500, the outer wall of the limiting plate 4 contacts the side wall of the contact block 6.
[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A rotating ring 3 is rotatably fitted on the fixed ring 2, and a limit plate 4 is fixedly connected to the outer wall of the rotating ring 3.
[0032] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the button 100 is provided with an external thread, and the inner wall of the retaining ring 2 is provided with an internal thread 200. When the retaining ring 2 is installed on the button 100, the external thread and the internal thread 200 are threadedly engaged.
[0033] The number of turns of the external thread ensures that the retaining ring 2 can be completely disengaged from the button 100 after rotating counterclockwise 270°, thus avoiding interference from the limit seat 5 during disassembly.
[0034] In addition, after the fixing ring 2 is assembled, there is a gap between it and the top of the tactile switch body 1, which ensures that when the button 100 is pressed after the limit plate 4 is rotated out, the normal operation of the button 100 can be effectively guaranteed.
[0035] Reference Figure 3 The outer wall of the fixed ring 2 is provided with an annular mounting groove 201, and the rotating ring 3 is rotatably engaged with the annular mounting groove 201.
[0036] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 When the limiting plate 4 rotates into the limiting groove 500, the top and bottom of the limiting plate 4 contact the top and bottom surfaces of the limiting groove 500, respectively.
[0037] Reference Figure 5 The inner walls of the assembly slot 501 are provided with sliding grooves on both sides.
[0038] Reference Figure 5 and Figure 6The abutment block 6 includes a rectangular block, with sliders fixed on both sides of the rectangular block. The sliders slide in conjunction with the slide groove. A trapezoidal block is fixed at the bottom of the rectangular block. The trapezoidal block is an isosceles trapezoid, and wear-resistant pads are provided on the inclined surfaces of the trapezoidal block. The sliding contact between the sliders and the slide groove ensures that the abutment block 6 slides stably up and down in the assembly groove 501, preventing displacement. The wear-resistant pads are made of materials with excellent wear resistance, such as polyurethane, which can effectively reduce wear when in contact with the limiting plate 4 and extend service life.
[0039] Working principle: When the tactile switch is needed, the user manually rotates the rotating ring 3, causing the limiting plate 4 to rotate out of the limiting groove 500. At this time, the button 100 is in an operable state, and the user can press the button normally to realize the switch function. After use, the rotating ring 3 is rotated again to make the limiting plate 4 rotate into the limiting groove 500. During the process of the limiting plate 4 entering the limiting groove 500, the outer wall of the limiting plate 4 pushes the abutment block 6 to move upward and compresses the spring 7. When the limiting plate 4 is fully inserted into the limiting groove, the elastic force of the spring 7 pushes the abutment block 6 to move downward, so that the trapezoidal block of the abutment block 6 blocks and limits the limiting plate 4, forming a stable limiting structure, which effectively prevents the button from being accidentally touched by external factors.
[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
