Description

Technical Field

[0001] This utility model relates to the field of DIP switch technology, and specifically discloses a DIP switch with an anti-accidental touch structure. Background Technology

[0002] A DIP switch is an electronic component that uses a manually toggled lever to switch circuit on / off states or coded states. It is widely used in electronic equipment, instrumentation, industrial control, and smart home applications, primarily for parameter setting, address encoding, and function mode selection. Its core advantages lie in its intuitive and convenient operation, requiring no complex circuitry for state switching. Once set, the state remains stable, exhibiting strong anti-interference capabilities and maintaining its preset state even under vibration and electromagnetic interference. Therefore, it is widely used in electronic systems requiring manual intervention.

[0003] However, existing DIP switches have two significant shortcomings in practical use:

[0004] On the one hand, the toggle of a DIP switch is usually directly exposed to the external environment and lacks a targeted protective structure. It is easy for the toggle to be accidentally moved due to accidental touch, collision or other unexpected situations, which will cause the preset circuit on / off state or coding information to be changed, resulting in problems such as abnormal equipment function, parameter disorder or even shutdown, increasing the instability of equipment operation.

[0005] On the other hand, the toggle area of ​​existing DIP switches often lacks an effective sealing structure, which cannot prevent liquids (such as water droplets, coolant, etc.) from splashing or seeping in. After liquid enters the connection between the toggle and the circuit, it may cause short circuits, oxidation and corrosion of metal contacts, resulting in poor contact. In severe cases, it may damage the entire switch and even the associated circuit, significantly reducing the reliability and service life of the equipment.

[0006] Therefore, a DIP switch with an anti-accidental touch structure is needed to solve the above problems. Utility Model Content

[0007] This invention proposes a DIP switch with an anti-accidental touch structure to prevent accidental activation of the DIP switch due to accidental touch, collision, or other unexpected situations. This prevents the preset circuit on / off state or encoded information from being altered, thereby avoiding problems such as abnormal equipment function, parameter errors, or even shutdown. At the same time, it can effectively prevent liquid from splashing or seeping into the DIP switch area, preventing short circuits, oxidation and corrosion of metal contacts, and poor contact, thus improving the reliability and service life of the equipment.

[0008] This utility model is implemented as follows: a DIP switch with an anti-accidental contact structure includes a DIP switch body, the right side of the DIP switch body has multiple switches, and an anti-accidental contact mechanism is provided on the outside of the DIP switch body.

[0009] The anti-accidental contact mechanism includes a frame fixedly connected to the outer wall of the DIP switch body. A connecting plate is fixedly connected to the upper end of the frame. A circular hole is opened through the outer wall of the connecting plate. A connecting rod passes through the circular hole. A disc is fixedly connected to the left end of the connecting rod. A rotating ring is provided on the left side of the connecting plate. A compression spring sleeved on the outer wall of the connecting rod is fixedly connected between the rotating ring and the disc. A vertical plate is fixedly connected to the right end of the connecting rod. A rectangular frame is fixedly connected to the lower end of the vertical plate. An anti-touch plate is installed inside the rectangular frame. A limit groove is opened inside the rectangular frame. A limit frame extending into the limit groove is fixedly connected to the right end of the frame.

[0010] A sealing gasket is installed at the right end of the frame, which abuts against the left end of the rectangular frame.

[0011] As a preferred embodiment of the DIP switch with an anti-accidental-touch structure of this utility model, the right end of the rotating ring is equipped with an annular slide rail, and the rotating ring is slidably connected to the left side of the connecting plate through the annular slide rail.

[0012] In a preferred embodiment of this utility model, the anti-touch plate is made of a transparent material.

[0013] In a preferred embodiment of this utility model, the connecting rod and the inside of the circular hole are in a clearance fit.

[0014] In a preferred embodiment of this utility model, the outer wall of the limiting frame and the inner wall of the limiting groove are in clearance fit.

[0015] As a preferred embodiment of the DIP switch with an anti-accidental contact structure of the present invention, the right edge of the outer wall of the limiting frame is chamfered.

[0016] In a preferred embodiment of this utility model, a DIP switch with an anti-accidental contact structure is provided, wherein the sealing gasket is made of EPDM rubber.

[0017] The beneficial effects of this utility model are:

[0018] 1. During operation, first pull the rectangular frame to the right and compress the compression spring until the limit frame disengages from the limit groove. Then rotate the rectangular frame and the anti-touch plate 180 degrees to expose the lever, thereby setting the lever. After setting, return the rectangular frame to its original position and align the limit frame with the limit groove. After releasing the tension, the spring force will cause the rectangular frame to tightly abut against the sealing gasket of the frame, and the limit frame will re-insert into the limit groove and lock in place. This process ensures that the anti-touch plate is always located on the side of the lever when not in operation, thus effectively preventing the lever from being accidentally moved due to accidental touch, collision, or other unexpected situations. This prevents the preset circuit on / off state or coding information from being changed, thereby avoiding problems such as abnormal equipment function, parameter errors, or even shutdown.

[0019] 2. The tight seal between the frame and the rectangular frame, achieved through a sealing gasket, effectively prevents liquid from splashing or seeping into the lever area, thus preventing short circuits, oxidation and corrosion of metal contacts, and poor contact, significantly improving the reliability and service life of the equipment.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0028] Please see Figure 1-5 A DIP switch with an anti-accidental contact structure includes a DIP switch body 1, a plurality of toggle switches 2 on the right side of the DIP switch body 1, and an anti-accidental contact mechanism on the outside of the DIP switch body 1.

[0029] The anti-accidental contact mechanism includes a frame 3 fixedly connected to the outer wall of the DIP switch body 1. A connecting plate 4 is fixedly connected to the upper end of the frame 3. A circular hole 5 is opened through the outer wall of the connecting plate 4. A connecting rod 6 is inserted through the circular hole 5. A disc 7 is fixedly connected to the left end of the connecting rod 6. A rotating ring 8 is provided on the left side of the connecting plate 4. A compression spring 9 sleeved on the outer wall of the connecting rod 6 is fixedly connected between the rotating ring 8 and the disc 7. A vertical plate 10 is fixedly connected to the right end of the connecting rod 6. A rectangular frame 11 is fixedly connected to the lower end of the vertical plate 10. An anti-touch plate 12 is installed inside the rectangular frame 11. A limit groove 13 is opened inside the rectangular frame 11. A limit frame 14 extending into the limit groove 13 is fixedly connected to the right end of the frame 3.

[0030] A sealing gasket 16 is installed on the right end of the frame 3, which abuts against the left end of the rectangular frame 11.

[0031] In this embodiment: when it is necessary to operate the lever 2 on the right side of the DIP switch body 1, first pull the rectangular frame 11 to the right, and drive the connecting rod 6 and the disc 7 to move to the right through the vertical plate 10. At this time, the connecting rod 6 slides in the circular hole 5 of the connecting plate 4 and compresses the compression spring 9 fixed between the rotating ring 8 and the disc 7 until the limiting frame 14 is dislodged from the limiting groove 13. Then rotate the rectangular frame 11 to make the connecting rod 6 rotate freely inside the circular hole 5, drive the compression spring 9 and the disc 7 to rotate with the rotating ring 8, and at the same time drive the rectangular frame 11 and the anti-touch plate 12 to rotate 180 degrees, completely exposing the lever 2 of the DIP switch body 1. The operator can directly move the lever 2 to set the circuit on / off state or encoding information.

[0032] After setting, rotate the rectangular frame 11 back to its initial position, align the limiting frame 14 with the limiting groove 13, release the tension on the rectangular frame 11, and the spring force of the compression spring 9 pushes the disc 7 and the connecting rod 6 to slide to the left, so that the left end of the rectangular frame 11 is tightly abutted against the sealing gasket 16 at the right end of the frame 3. The limiting frame 14 is reinserted into the limiting groove 13. Through the cooperation of the limiting frame 14 and the limiting groove 13, the rotation of the rectangular frame 11 is restricted. At this time, the anti-touch plate 12 inside the rectangular frame 11 is located to the right of the lever 2, which prevents the lever 2 from being accidentally moved due to accidental touch, collision or other unexpected situations, and prevents the preset circuit on / off state or coding information from being changed, thereby avoiding problems such as abnormal equipment function, parameter disorder or even shutdown.

[0033] Meanwhile, since the sealing effect is achieved between the frame 3 and the rectangular frame 11 through the sealing gasket 16, it can effectively prevent liquid from splashing or seeping into the area of ​​the lever 2, preventing short circuits, oxidation and corrosion of metal contacts and poor contact, thereby improving the reliability and service life of the equipment.

[0034] It should be noted that the main body 1 of the DIP switch is existing technology. It mainly consists of a shell, internal metal conductive contacts, pins and levers 2. It changes the on / off state of the metal contacts by moving the levers 2. The combination of multiple levers 2 on / off states forms a binary encoded signal to realize parameter setting or function selection. Since the core structure of the main body 1 of the DIP switch is existing technology, the detailed internal structure is not shown in the figure. The improvement of this utility model is mainly in the newly added anti-accidental contact mechanism and sealing structure.

[0035] As a technical optimization of this utility model, an annular slide rail 15 is installed on the right end of the rotating ring 8, and the rotating ring 8 is slidably connected to the left side of the connecting plate 4 through the annular slide rail 15.

[0036] In this embodiment: when the compression spring 9 and the disc 7 rotate with the connecting rod 6, due to the setting of the annular slide rail 15, the compression spring 9 will rotate synchronously with the rotating ring 8, avoiding the limiting effect on the compression spring 9.

[0037] As a technical optimization of this utility model, the anti-touch plate 12 is made of transparent material.

[0038] In this embodiment, the anti-touch plate 12 is made of transparent material, so the current state of the paddle 2 can be directly observed through the anti-touch plate 12, which takes into account both protection and ease of observation.

[0039] As a technical optimization of this utility model, the connecting rod 6 and the inside of the circular hole 5 are in clearance fit.

[0040] In this embodiment, the connecting rod 6 and the inside of the circular hole 5 are in clearance fit, which ensures that the connecting rod 6 can slide smoothly left and right in the circular hole 5, and also allows the connecting rod 6 to rotate freely around the axis of the circular hole 5.

[0041] As a technical optimization of this utility model, the outer wall of the limiting frame 14 and the inner wall of the limiting groove 13 are in clearance fit.

[0042] In this embodiment, the outer wall of the limiting frame 14 and the inner wall of the limiting groove 13 are in clearance fit. When the rectangular frame 11 is reset, the positioning of the rectangular frame 11 is achieved by embedding the limiting frame 14 into the limiting groove 13, while avoiding the rectangular frame 11 from being difficult to insert or detach due to excessive tightness, thus ensuring smooth operation.

[0043] As a technical optimization of this utility model, the right edge of the outer wall of the limiting frame 14 is chamfered.

[0044] In this embodiment, the right edge of the outer wall of the limiting frame 14 is chamfered. During the resetting process of the rectangular frame 11, the chamfer can guide the limiting frame 14 to slide quickly and accurately into the limiting groove 13 of the rectangular frame 11, reducing the difficulty of alignment.

[0045] As a technical optimization of this utility model, the sealing gasket 16 is made of EPDM rubber.

[0046] In this embodiment, the sealing gasket 16 is made of EPDM rubber, which has good elasticity, water resistance and aging resistance, thus improving the reliability and service life of the seal.

[0047] The working principle and usage process of this utility model are as follows: When it is necessary to operate the dial switch body 1 with the right side of the dial switch 2, first pull the rectangular frame 11 to the right. The vertical plate 10 drives the connecting rod 6 and the disc 7 to move to the right. At this time, the connecting rod 6 slides in the circular hole 5 of the connecting plate 4 and compresses the compression spring 9 fixed between the rotating ring 8 and the disc 7 until the limit frame 14 is dislodged from the limit groove 13. Then, rotate the rectangular frame 11 to make the connecting rod 6 rotate freely inside the circular hole 5, and drive the compression spring 9 and the disc 7 to rotate with the rotating ring 8. At the same time, drive the rectangular frame 11 and the anti-touch plate 12 to rotate 180 degrees, completely exposing the dial switch body 1's dial switch 2. The operator can directly move the dial switch 2 to set the circuit on / off status or encoding information.

[0048] After setting, rotate the rectangular frame 11 back to its initial position, align the limiting frame 14 with the limiting groove 13, release the tension on the rectangular frame 11, and the spring force of the compression spring 9 pushes the disc 7 and the connecting rod 6 to slide to the left, so that the left end of the rectangular frame 11 is tightly abutted against the sealing gasket 16 at the right end of the frame 3. The limiting frame 14 is reinserted into the limiting groove 13. Through the cooperation of the limiting frame 14 and the limiting groove 13, the rotation of the rectangular frame 11 is restricted. At this time, the anti-touch plate 12 inside the rectangular frame 11 is located to the right of the lever 2, which prevents the lever 2 from being accidentally moved due to accidental touch, collision or other unexpected situations, and prevents the preset circuit on / off state or coding information from being changed, thereby avoiding problems such as abnormal equipment function, parameter disorder or even shutdown.

[0049] Meanwhile, since the sealing effect is achieved between the frame 3 and the rectangular frame 11 through the sealing gasket 16, it can effectively prevent liquid from splashing or seeping into the area of ​​the lever 2, preventing short circuits, oxidation and corrosion of metal contacts and poor contact, thereby improving the reliability and service life of the equipment.
