Abstract
Description
Technical Field
[0001] This utility model relates to the field of coding switch technology, specifically to an ultra-thin patch rotary coding switch. Background Technology
[0002] A rotary encoder, also known as a coding switch, is an electronic device that converts mechanical displacement or signal input into electrical signal output. It is widely used in industrial control, instrumentation, and home appliances. Its main function is to convert changes in rotation angle or position into digital pulse signals, thereby enabling precise control of equipment and data acquisition. With the trend towards thinner and smaller electronic products, ultra-thin surface-mount rotary encoders have gradually become the mainstream product in the market due to their small size, low thickness, and easy installation.
[0003] However, in existing technologies, ultra-thin surface-mount rotary encoder switches still present certain problems during actual installation. Particularly in the soldering process, these encoder switches typically require pin mounting and soldering onto the circuit board. During soldering, the encoder switch body is prone to shifting or tilting, leading to frequent adjustments, weak solder joints, poor contact, or even cold solder joints. This not only reduces the efficiency of soldering and installation but may also affect the electrical performance and mechanical stability of the encoder switch, thus adversely impacting the overall performance and reliability of the product.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] In view of the problems in the related technologies, this utility model proposes an ultra-thin patch rotary encoder switch to overcome the above-mentioned technical problems existing in the existing related technologies.
[0006] Therefore, the specific technical solution adopted by this utility model is as follows:
[0007] An ultra-thin surface mount rotary encoder switch includes an encoder switch body, metal surface mount pins mounted on both sides of the bottom of the encoder switch body, adjustment slots on both sides of the metal surface mount pins, a rotating shaft mounted on the top of the encoder switch body, positioning boxes slidably mounted on both sides inside the adjustment slots, a welding positioning mechanism inside the positioning boxes, and a positioning adjustment mechanism between the adjustment slots and the positioning boxes.
[0008] Furthermore, in order to ensure that the coded switch body can be stably attached to the circuit board during metal patch pin soldering, the soldering positioning mechanism includes a telescopic groove inside the positioning box, a support rod slidingly installed inside the telescopic groove, a limit ring connected to one side of the support rod, a telescopic spring connected to the bottom surface of the limit ring, the end of the telescopic spring being fixedly connected inside the positioning box, and a rubber suction cup installed at the bottom end of the support rod.
[0009] Furthermore, in order to facilitate the downward movement of the support rod and rubber suction cup during the metal patch pin welding adsorption, an extrusion plate is slidably installed inside the adjustment groove. The two sides of the extrusion plate are connected to transmission rods, and the top of the transmission rod passes through the encoder switch body and is connected to a bearing rod.
[0010] Furthermore, in order to adjust the position of the positioning box, the positioning adjustment mechanism includes a limiting groove on one side of the adjustment groove, a limiting screw connected to one side of the positioning box, the limiting screw being slidably installed in the limiting groove, and a clamping nut being threadedly connected to one side of the surface of the limiting screw.
[0011] Furthermore, in order to increase the friction between the bottom of the encoder switch body and the circuit board during soldering, an anti-slip pad is installed on the bottom of the encoder switch body.
[0012] Furthermore, in order to increase the friction when the rotating shaft is connected to the object to be tested, the surface of the rotating shaft is provided with anti-slip texture.
[0013] Furthermore, in order to enable the transmission rod to slide up and down within the encoder switch body, sliding grooves are provided on both sides of the encoder switch body, and the transmission rod is slidably installed within the sliding grooves.
[0014] The beneficial effects of this utility model are as follows: Through the welding positioning mechanism, after the metal patch pins on the bottom surface of the encoder switch body are aligned and placed at the required welding position, the rubber suction cup is pressed and adsorbed onto the surface of the circuit board. At this time, the reset spring in the welding positioning mechanism is squeezed and, through its own elastic force, it can make the encoder switch body stick tightly to the circuit board, effectively preventing the encoder switch body from shifting or tilting during the welding process, which facilitates the welding of the metal patch pins. This structure not only improves the welding accuracy and efficiency, but also significantly enhances the reliability of the connection between the pins and the circuit board, and reduces the defect rate of poor soldering, misalignment and other defects.

[0023] 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.
[0024] According to an embodiment of the present invention, an ultra-thin patch rotary encoder switch is provided.
[0025] Example 1:
[0026] like Figures 1-5As shown, an ultra-thin surface-mount rotary encoder switch according to an embodiment of the present invention includes an encoder switch body 1, which consists of a protective shell, an encoder disk, a dome switch, a brush disk, and a dial switch, capable of converting rotational position into an electrical signal for output; metal surface-mount pins 2 are installed on both sides of the bottom of the encoder switch body 1, and there are three pairs of metal surface-mount pins 2, which are used to solder onto the circuit board to realize signal transmission; adjustment slots 3 are opened on both sides of the metal surface-mount pins 2, and a rotating shaft 4 is installed on the top of the encoder switch body 1; a pair of positioning boxes 5 are slidably installed on both sides inside the adjustment slots 3, and a welding positioning mechanism 6 is provided inside the positioning boxes 5, which enables the encoder switch body 1 to be adsorbed onto the surface of the circuit board when the metal surface-mount pins 2 are soldered; a positioning adjustment mechanism 7 is provided between the adjustment slots 3 and the positioning boxes 5, which is used to adjust the position of the positioning boxes 5 in the adjustment slots 3, so that the welding positioning mechanism 6 can be stably adsorbed onto the smooth surface of the circuit board.
[0027] like Figures 1-5As shown, the welding positioning mechanism 6 includes a telescopic groove 601 inside the positioning box 5. A support rod 602 is slidably installed inside the telescopic groove 601. A limit ring 603 is connected to one side of the surface of the support rod 602. A telescopic spring 604 is connected to the bottom surface of the limit ring 603. The end of the telescopic spring 604 is fixedly connected inside the positioning box 5. A rubber suction cup 605 is installed at the bottom end of the support rod 602. By pressing the support rod 602, the support rod 602 drives the rubber suction cup 605 to move downward, so that when the metal surface mount pin 2 is being welded, the rubber suction cup 605 can be adsorbed onto the surface of the circuit board. The compression spring 604 is compressed by the downward movement of the limiting ring 603. When compressed, its own elasticity allows the encoder switch body 1 to adhere tightly to the circuit board, thus maintaining the stability of the encoder switch body 1 during soldering. A pressing plate 606 is slidably installed inside the adjusting groove 3. A pair of transmission rods 607 are connected to both sides of the pressing plate 606. The top of the transmission rods 607 passes through the encoder switch body 1 and connects to a bearing rod 608. Sliding grooves 10 are opened on both sides of the encoder switch body 1, and the transmission rods 607 are slidably installed within the sliding grooves 10. During soldering, pressing down on the bearing rod 608 allows the bearing rod 608 to pass through... The transmission rod 607 drives the extrusion plate 606 to move downwards, thereby enabling the extrusion plate 606 to push down the two support rods 602 in the adjustment groove 3, facilitating the adsorption of the rubber suction cup 605. The positioning adjustment mechanism 7 includes a limiting groove 701 on one side of the adjustment groove 3, and a limiting screw 702 connected to one side of the positioning box 5. The limiting screw 702 is slidably installed in the limiting groove 701, and a clamping nut 703 is threadedly connected to one side of the surface of the limiting screw 702. By sliding the positioning box 5 in the adjustment groove 3, the adsorption position of the rubber suction cup 605 on the circuit board can be changed, thereby facilitating the soldering of the metal patch pins 2. The rubber suction cup 605 can adhere to the smooth surface of the circuit board after adjustment. After the positioning box 5 is adjusted, the friction between the clamping nut 703 and the two sides of the limiting groove 701 is increased by tightening the clamping nut 703, thereby stabilizing and limiting the adjusted positioning box 5. The bottom of the encoder switch body 1 is equipped with a rubber anti-slip pad 8, which further increases the friction between the encoder switch body 1 and the circuit board during installation, preventing the encoder switch body 1 from shifting. The surface of the rotating shaft 4 is provided with anti-slip texture 9, which increases the friction between the rotating shaft 4 and the object to be detected, preventing slippage.
[0028] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.
[0029] In summary, with the help of the above-mentioned technical solution of this utility model, in actual use, after the metal patch pins 2 on the bottom surface of the encoder switch body 1 are aligned and placed on the circuit board at the positions to be soldered, the positioning box 5 can be slid in the adjustment groove 3 by pushing the limiting screw 702, which can change the corresponding adsorption position of the rubber suction cup 605 on the circuit board. This ensures that before soldering the metal patch pins 2, the rubber suction cup 605 can be aligned with the smooth surface of the circuit board after adjustment. By pressing down on the bearing rod 608 before soldering, the bearing rod 608 is moved through the transmission rod 60... 7. The extrusion plate 606 is moved downward, which allows the extrusion plate 606 to push the two support rods 602 in the adjustment groove 3 downward. At this time, the support rods 602 drive the rubber suction cup 605 to move downward, so that the rubber suction cup 605 is adsorbed on the surface of the circuit board. The telescopic spring 604 is compressed by the downward movement of the limiting ring 603. After being squeezed, it can make the encoder switch body 1 stick tightly to the circuit board through its own elasticity, thereby maintaining the stability of the encoder switch body 1 during welding and effectively preventing the encoder switch body 1 from shifting or tilting during the welding process.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
