Description

Technical Field

[0001] This utility model relates to the field of tactile switch technology, specifically a quick-installation tactile switch. Background Technology

[0002] A tactile switch is a common electronic component, typically used to control the switching state of a circuit. Usually, pressing the switch button lightly closes or opens the circuit. The working principle of a tactile switch is usually based on mechanical contact or capacitive sensing. In a mechanical contact tactile switch, pressing the switch will make the internal contacts make contact, forming a circuit; while in a capacitive switch, pressing will change the capacitance value, thereby triggering the circuit.

[0003] In the prior art, Chinese Patent Application No. CN202010532251.X discloses a tactile switch, including a top cover, a base, a button, a bracket, an elastic element, a first terminal, and a second terminal. The base has an upward-opening receiving cavity, and a hollow column protruding upward from the bottom surface of the base. The bracket and the elastic element are sequentially sleeved on the column from top to bottom and located within the receiving cavity. The top cover and the button are sequentially stacked on the top surface of the base from top to bottom. The top cover and the base are detachably connected. The button has an upward-protruding cap. The top cover has a hollow hole for the cap to pass through. The bottom surface of the cap also has a downward-protruding annular structure. There is a gap between the outer wall of the annular structure and the inner wall of the cap, forming an annular groove that engages with the column. The bracket has a first terminal, and the base has a second terminal. The first terminal and the second terminal are in contact to connect the circuit. The elastic element always has a tendency to drive the first terminal and the second terminal apart.

[0004] Based on the above information, it can be seen that in the prior art, tactile switches are generally mounted on circuit boards. During installation, their pins need to be soldered to the circuit board for fixation. However, in the actual installation process, the pins of the tactile switch need to be aligned with the soldering position on the circuit board. Without initial fixing measures, the switch is prone to displacement during soldering, requiring constant adjustments by the staff, which affects the installation efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a quick-installation tactile switch to solve the problem of efficiency being affected by positional misalignment during welding installation, as mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-installation tactile switch, comprising a switch body, the switch body being mounted above a mounting circuit board, the switch body being divided into a first housing and a second housing, the first housing and the second housing being fixedly installed together by bolts, and a welded metal sheet being fixedly installed on the lower surface of the first housing, while a limiting buckle for limiting its movement during installation is fixedly installed on the lower surface of the first housing; a switch button is installed inside the second housing, and the switch button and the second housing form a through-type up-and-down sliding structure, and a built-in circuit board with contacts is fixedly installed inside the second housing.

[0007] Preferably, the lower end of the limiting buckle is configured as a hook-shaped structure, and a support pad is fixedly installed on the lower surface of the first housing, and the lower surface of the support pad is flush with the lower surface of the welded metal sheet.

[0008] Preferably, the mounting circuit board has a first limiting groove and a second limiting groove inside, and the first limiting groove and the second limiting groove are interconnected.

[0009] Preferably, the cross-sectional area of ​​the first limiting groove is larger than the cross-sectional area of ​​the lower end of the limiting buckle, and the upper end of the limiting buckle slides against the second limiting groove.

[0010] Preferably, a reset spring is fixedly installed between the switch button and the built-in circuit board, and the lower surface of the switch button is connected to a contact post corresponding to the contact point on the built-in circuit board.

[0011] Preferably, vertically mounted compression rods are fixedly installed on the left and right sides of the lower end of the switch button, and the lower ends of the compression rods correspond to the positions of the reset spring.

[0012] Preferably, the lower end of the reset spring is slidably mounted between the reset spring and the mounting groove, and the mounting groove is formed on the upper surface of the built-in circuit board.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this quick-installation tactile switch adopts a novel structural design, the specific details of which are as follows:

[0014] 1. Weld the welding metal sheet to the mounting circuit board to achieve the purpose of installing the switch body. Before this, insert the lower end of the limit buckle into the first limit slide groove opened inside the mounting circuit board. Then slide the limit buckle into the second slide groove to form a locking structure, thereby limiting and fixing the first housing and avoiding positional displacement during subsequent welding, which would affect the installation efficiency.

[0015] Furthermore, a support pad flush with the welded metal sheet is fixedly installed on the lower surface of the first housing to keep the switch body horizontal and stable.

[0016] 2. When the switch button is pressed, the contact post on the lower surface of the switch button contacts the contact point on the upper surface of the built-in circuit board to send a signal, thereby controlling the switch. Then, the elasticity of the reset spring lowers the switch button to reset.

[0017] Furthermore, the reset spring on the upper surface of the built-in circuit board is pressed by the squeezing rods on both sides when the control button is moved downward. Then, the elasticity of the reset spring is used to assist in the reset, so as to avoid the reset spring from becoming fatigued after long-term use and affecting normal use.

[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 protection scope of the present utility model.

[0027] Example 1: Please refer to Figures 1-4 In order to achieve the purpose of initial fixation and improve the efficiency of subsequent welding and installation, this embodiment provides the following technical solution, which specifically discloses: a switch body 1, which is installed above the mounting circuit board 2. The switch body 1 is divided into two parts: a first housing 101 and a second housing 102. The first housing 101 and the second housing 102 are fixedly installed with bolts. A welding metal sheet 3 is fixedly installed on the lower surface of the first housing 101. At the same time, a limiting buckle 5 for limiting its installation is fixedly installed on the lower surface of the first housing 101. The lower end of the limiting buckle 5 is set as a hook structure. A support pad 6 is fixedly installed on the lower surface of the first housing 101. The lower surface of the support pad 6 is flush with the lower surface of the welding metal sheet 3. The mounting circuit board 2 has a first limiting groove 7 and a second limiting groove 8 inside. The first limiting groove 7 and the second limiting groove 8 are interconnected. The cross-sectional area of ​​the first limiting groove 7 is larger than the cross-sectional area of ​​the lower end of the limiting buckle 5. The upper end of the limiting buckle 5 slides against the second limiting groove 8.

[0028] When installing the switch body 1 onto the mounting circuit board 2, firstly, align the limiting buckle 5 on the lower surface of the first housing 101 with the first limiting groove 7 inside the mounting circuit board 2. Then, insert the lower end of the limiting buckle 5 into the first limiting groove 7. Next, slide the switch body 1 so that the middle position of the limiting buckle 5 slides into the second limiting groove 8 to form a locking structure. This uses the limiting buckle 5 to initially fix the switch body 1, preventing positional shifts during subsequent welding that would require constant adjustments by the operator. Then, the operator uses a welding device to weld the welding metal sheet 3 on the lower surface of the first housing 101 to the mounting circuit board 2. During this process, the support pad 6 supports the switch body 1 to ensure that it is parallel to the mounting circuit board 2.

[0029] Example 2: Please refer to Figures 5-7 In order to achieve the purpose of resisting elastic fatigue, this embodiment provides the following technical solution, specifically: a switch button 4 is installed inside the second housing 102, and the switch button 4 and the second housing 102 form a through-type up-and-down sliding structure. An internal circuit board 9 with contacts is fixedly installed inside the second housing 102. A return spring 11 is fixedly installed between the switch button 4 and the internal circuit board 9. The lower surface of the switch button 4 corresponds to the contact post 10 on the internal circuit board 9. Vertically installed extrusion rods 12 are fixedly installed on the left and right sides of the lower end of the switch button 4. The lower end of the extrusion rod 12 corresponds to the position of the return spring 13. The lower end of the return spring 13 is slidably installed between the installation groove 14 and the installation groove 14 is opened on the upper surface of the internal circuit board 9.

[0030] When the switch body 1 is installed and operation is required, press the switch button 4. At this time, the switch button 4 moves downward, and finally the contact post 10 on the lower surface of the switch button 4 contacts the contact point on the upper surface of the built-in circuit board 9, thereby connecting the signal and achieving the purpose of control. After releasing the press of the switch button 4, the switch button 4 is reset upward under the elastic action of the reset spring 11. During the downward movement of the switch button 4, the compression rods 12 on its left and right sides are used to compress the reset spring 13. Then, during the reset, the elastic action of the reset spring 13 is used to assist the reset, avoiding elastic fatigue of the reset spring 11 after long-term use.
