The screw terminals in traditional control switches are usually fixed inside the switch by simple threads. When the screw terminals are turned, they easily fall off the switch once the threaded connection is released.
[0004] The purpose of this invention is to solve the problem that the screw terminals of traditional control switches are prone to falling off. Utility Model Content
[0005] The purpose of this utility model is to solve the problem that the screw terminals of traditional control switches are prone to falling off. This utility model adopts the following technical solution:
[0006] A touch panel switch for preventing terminal detachment includes a back cover, a connecting post installed inside the back cover, a screw terminal sleeved inside the connecting post, the screw terminal being threadedly connected to the connecting post, and at least one first through slot being provided on one side of the back cover, the top of the screw terminal not being able to pass through the first through slot.
[0007] As described above, in a touch panel switch for preventing terminal detachment, the top view of the first through slot is crescent-shaped, and the shortest diameter of the first through slot is shorter than the diameter of the top of the screw terminal.
[0008] As described above, in a touch panel switch for preventing terminal detachment, the screw terminal has a vertical section, the vertical section has a thread that is threaded to the connecting post, and the height from the bottom of the vertical section to the top of the screw terminal is equal to, less than or greater than the distance from the top surface of the connecting post to the bottom of the first through groove.
[0009] As described above, in a touch panel switch designed to prevent terminal detachment, one end of the screw terminal is provided with a chamfered section.
[0010] In the touch panel switch described above for preventing terminal detachment, the top edge of the screw terminal is arc-shaped.
[0011] As described above, in a touch panel switch for preventing terminal detachment, at least one second through groove is provided on one side of the back cover, and a groove is provided on one side of the connecting post, the groove being connected to the second through groove.

[0028] 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.
[0029] like Figures 1 to 5As shown, this utility model proposes a touch panel switch to prevent terminal detachment, including a back cover 1. A connecting post 21 is installed inside the back cover 1, and a circuit board 2 is also installed inside the back cover 1. The connecting post 21 is mounted on the circuit board 2, and a screw terminal 22 is fitted inside the connecting post 21. The screw terminal 22 is threadedly connected to the connecting post 21. At least one first through slot 11 is provided on one side of the back cover 1, and the top of the screw terminal 22 cannot pass through the first through slot 11. When connecting a wire to the touch panel switch, the wire needs to be inserted into the connecting post 21, and then the screw terminal 22 is turned to press the wire firmly. Similarly, when disconnecting the wire, the screw terminal 22 needs to be turned in the opposite direction. During this process, the top of the screw terminal 22, due to its large size, will get stuck at the edge of the first through slot 11 and cannot pass through the first through slot 11 on the back cover 1. Therefore, it will not come out of the connecting post 21 even during loosening. Users do not need to worry about the screw terminal 22 accidentally falling off when connecting or disconnecting wires, thereby reducing maintenance costs and potential safety hazards.
[0030] Furthermore, as a preferred embodiment of this utility model and not a limitation, the top projection of the first through groove 11 is crescent-shaped, and the shortest diameter of the first through groove 11 is shorter than the diameter of the top of the screw terminal 22. The top diameter of the screw terminal 22 is larger than the shortest diameter of the first through groove 11, which means that the top of the screw terminal 22 cannot pass through the first through groove 11, and cannot be dislodged from the back cover 1 regardless of the rotation angle of the screw terminal 22. The crescent-shaped design allows the screw terminal 22 to move axially within a certain range, while providing sufficient space to rotate the screw terminal 22. This shape design allows the screw terminal 22 to rotate freely to clamp or loosen the wire, while ensuring that it will not come out of the first through groove 11.
[0031] Furthermore, as a preferred embodiment of this utility model and not a limitation, the screw terminal 22 is provided with a vertical section 222. The vertical section 222 has threads that are threaded to the connecting post 21. The height from the bottom of the vertical section 222 to the top of the screw terminal 22 is equal to the distance from the top surface of the connecting post 21 to the bottom of the first through groove 11. Because the threaded screw terminal 22 can be rotatably fixed within the connecting post 21, and the height from the bottom of the vertical section 222 to the top of the screw terminal 22 is equal to the distance from the top surface of the connecting post 21 to the bottom of the first through groove 11, this means that when the screw terminal 22 is unscrewed from the connecting post 21, and the top surface of the screw terminal 22 reaches the bottom of the first through groove 11, the threaded screw terminal 22 is just disengaged from the connecting post 21. Even if the threaded screw terminal 22 is rotated further, it will not move upwards, thus preventing the screw terminal 22 from continuing to rise and potentially damaging the first through groove 11. This ensures that the screw terminal 22 will not completely detach from the connecting post 21 under any circumstances, improving the reliability and service life of both.
[0032] Optionally, in some embodiments, the screw terminal 22 is provided with a vertical section 222, which has threads for threaded connection with the connecting post 21. The height from the bottom of the vertical section 222 to the top of the screw terminal 22 is greater than the distance from the top surface of the connecting post 21 to the bottom of the first through groove 11. When it is necessary to loosen the screw terminal 22 to disconnect the wire connection, the user rotates the screw terminal 22, causing it to move upward along the threads of the connecting post 21. Since the height of the vertical section 222 is greater than the distance from the top surface of the connecting post 21 to the bottom of the first through groove 11, when the screw terminal 22 rises to its maximum position, the user will feel the pressure change generated by the contact between the screw terminal 22 and the edge of the first through groove 11, thus knowing that the screw terminal 22 has reached its maximum loosening position. By providing clear tactile feedback, the user can avoid over-tightening the screw terminal 22, preventing it from continuing to rise and damaging the first through groove 11.
[0033] Optionally, in some embodiments, the screw terminal 22 is provided with a vertical section 222, which has threads for threaded connection with the connecting post 21. The height from the bottom of the vertical section 222 to the top of the screw terminal 22 is less than the distance from the top surface of the connecting post 21 to the bottom of the first through groove 11. When it is necessary to loosen the screw terminal 22 to disconnect the wire connection, the user rotates the screw terminal 22, causing it to move upward along the threads of the connecting post 21. Since the height of the vertical section 222 is less than the distance from the top surface of the connecting post 21 to the bottom of the first through groove 11, when the screw terminal 22 is completely screwed out of the connecting post 21, its top remains below the top surface of the connecting post 21 and does not touch the first through groove 11. This prevents the screw terminal 22 from coming off.
[0034] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, one end of the screw terminal 22 is provided with a chamfered section 221. The chamfered section 221 is provided at the end of the screw terminal 22 that is screwed into the connecting post 21. The chamfered section 221 is always provided inside the connecting post 21. The chamfered section 221 is always located inside the connecting post 21, and even when the screw terminal 22 is completely screwed out, its chamfered section 221 will prevent the screw terminal 22 from completely disengaging from the connecting post 21. The design of the chamfered section 221 helps to guide the screw terminal 22 into or out of the connecting post 21 during installation or disassembly.
[0035] Furthermore, as a preferred embodiment of this utility model and not a limitation, the top edge of the screw terminal 22 is arc-shaped. The arc shape of the top edge of the screw terminal 22 makes its contact with the first through groove 11 smoother, reducing wear or scratches that sharp edges might cause to the first through groove 11. This prevents the screw terminal 22 from coming out of the first through groove 11 due to damage to the first through groove 11.
[0036] Furthermore, as a preferred embodiment of this utility model and not a limitation, at least one second through groove 12 is provided on one side of the rear cover 1, and a groove 211 is provided on one side of the connecting post 21, the groove 211 being connected to the second through groove 12. When wiring, the user inserts the wire through the second through groove 12 on one side of the rear cover 1. The design of the second through groove 12 allows the wire to smoothly enter the groove 211 of the connecting post 21. This makes inserting and removing the wire more convenient and improves the ease of operation.
[0037] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the rear cover 1 is provided with a frame 13, the frame 13 being provided with a plurality of chambers, and the connecting post 21 being installed in the chambers. The frame 13 enhances the rigidity around the first through groove 11, preventing deformation or damage that may occur during long-term use.
[0038] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the second through slot 12 is provided with a stop 14. The stop 14 needs to be removed when wiring the touch panel switch for the first time. The design of the stop 14 effectively prevents dust and foreign objects from entering the area where the connecting post 21 is located before wiring, thus protecting the cleanliness of the inside of the device.
[0039] Furthermore, as a preferred embodiment of this utility model and not a limitation, the top of the screw terminal 22 is provided with a first groove 223 and a second groove 224. The second groove 224 intersects the first groove 223 perpendicularly, and both ends of the second groove 224 extend to the two side edges of the screw terminal 22. When tightening the screw terminal 22, the user can insert a screwdriver into the first groove 223 or the second groove 224. The user can insert the screwdriver into the groove from different directions to better rotate the screw terminal 22. The first groove 223 and the second groove 224 intersect perpendicularly, forming a cross-shaped structure. The user can tighten the screw terminal 22 using a flathead or Phillips head screwdriver. The two ends of the second groove 224 extend to the two side edges of the screw terminal 22, meaning that when using a flathead screwdriver to tighten the screw terminal 22, even if the width of the flathead screwdriver is greater than the length of the second groove 224, it can still be smoothly inserted and engaged in the second groove 224, providing high flexibility.
[0040] The implementation method of Example 1 is as follows:
[0041] This invention proposes a touch panel switch to prevent terminal detachment, comprising a back cover 1, a connecting post 21 installed inside the back cover 1, a circuit board 2 installed inside the back cover 1, the connecting post 21 mounted on the circuit board 2, and a screw terminal 22 sleeved inside the connecting post 21, the screw terminal 22 being threadedly connected to the connecting post 21. At least one first through slot 11 is provided on one side of the back cover 1, and the top of the screw terminal 22 cannot pass through the first through slot 11. When connecting a wire to the touch panel switch, the wire needs to be inserted into the connecting post 21 and then the screw terminal 22 is turned to press the wire firmly. Similarly, when disconnecting the wire, the screw terminal 22 needs to be turned in the opposite direction. During this process, the top of the screw terminal 22, due to its large size, will get stuck at the edge of the first through slot 11 and cannot pass through the first through slot 11 on the back cover 1. Therefore, even during loosening, it will not come out of the connecting post 21. Users do not need to worry about the screw terminal 22 accidentally falling out when connecting or disconnecting wires, thereby reducing maintenance costs and potential safety hazards.
[0042] The first through slot 11 has a crescent shape in its top orthographic projection, and its shortest diameter is shorter than the diameter of the top of the screw terminal 22. The top diameter of the screw terminal 22 is larger than the shortest diameter of the first through slot 11, meaning that the top of the screw terminal 22 cannot pass through the first through slot 11 and cannot be dislodged from the back cover 1 regardless of its rotation angle. The crescent shape allows the screw terminal 22 to move axially within a certain range while providing sufficient space to rotate it. This shape allows the screw terminal 22 to rotate freely to clamp or loosen the wire while ensuring it does not dislodge from the first through slot 11.
[0043] The screw terminal 22 is provided with a vertical section 222, which has threads for threaded connection with the connecting post 21. The height from the bottom of the vertical section 222 to the top of the screw terminal 22 is equal to the distance from the top surface of the connecting post 21 to the bottom of the first through groove 11. The threaded screw terminal 22 can be rotatably fixed within the connecting post 21. The fact that the height from the bottom of the vertical section 222 to the top of the screw terminal 22 is equal to the distance from the top surface of the connecting post 21 to the bottom of the first through groove 11 means that when the screw terminal 22 is unscrewed from the connecting post 21, the top surface of the screw terminal 22 reaches the bottom of the first through groove 11, at which point the threaded screw terminal 22 is just disengaged from the connecting post 21. Even if the threaded screw terminal 22 is rotated further, it will not move upwards, thus preventing the screw terminal 22 from continuing to rise and potentially damaging the first through groove 11. This ensures that the screw terminal 22 will not completely detach from the connecting post 21 under any circumstances, improving the reliability and service life of both.
[0044] One end of the screw terminal 22 is provided with a chamfered section 221. The chamfered section 221 is located at the end of the screw terminal 22 that screws into the connecting post 21. The chamfered section 221 is always located inside the connecting post 21. The chamfered section 221 is always located inside the connecting post 21, and even when the screw terminal 22 is completely screwed out, its chamfered section 221 will prevent the screw terminal 22 from completely coming out of the connecting post 21. The design of the chamfered section 221 helps guide the screw terminal 22 into or out of the connecting post 21 during installation or disassembly. The top edge of the screw terminal 22 is arc-shaped. The top edge of the screw terminal 22 has a certain curvature, which makes the screw terminal 22 smoother when it contacts the first through groove 11, reducing the wear or scratches that sharp edges may cause to the first through groove 11. This avoids the screw terminal 22 from coming out of the first through groove 11 due to damage to the first through groove 11.
[0045] At least one second through slot 12 is provided on one side of the rear cover 1, and a groove 211 is provided on one side of the connecting post 21, the groove 211 being connected to the second through slot 12. When wiring, the user inserts the wire through the second through slot 12 on one side of the rear cover 1. The design of the second through slot 12 allows the wire to smoothly enter the groove 211 of the connecting post 21, making wire insertion and removal more convenient and improving operational ease.
[0046] The rear cover 1 is provided with a frame 13, which has a plurality of chambers, and the connecting post 21 is installed in the chambers. The frame 13 can enhance the rigidity around the first through groove 11 and prevent deformation or damage that may occur during long-term use.
[0047] The implementation method of Example 2 is as follows:
[0048] The difference between Embodiment 2 and Embodiment 1 is that the screw terminal 22 is provided with a vertical section 222. This vertical section 222 has threads that connect to the connecting post 21. The height from the bottom of the vertical section 222 to the top of the screw terminal 22 is greater than the distance from the top surface of the connecting post 21 to the bottom of the first through groove 11. When it is necessary to loosen the screw terminal 22 to disconnect the wire connection, the user rotates the screw terminal 22, causing it to move upwards along the threads of the connecting post 21. Because the height of the vertical section 222 is greater than the distance from the top surface of the connecting post 21 to the bottom of the first through groove 11, when the screw terminal 22 rises to its maximum position, the user will feel the pressure change caused by the contact between the screw terminal 22 and the edge of the first through groove 11, thus knowing that the screw terminal 22 has reached its maximum loosening position. By providing clear tactile feedback, the user can avoid over-tightening the screw terminal 22, preventing it from continuing to rise and damaging the first through groove 11.
[0049] The implementation method of Example 3 is as follows:
[0050] The difference between Embodiment 3 and Embodiment 1 is that the screw terminal 22 is provided with a vertical section 222. This vertical section 222 has threads that connect to the connecting post 21. The height from the bottom of the vertical section 222 to the top of the screw terminal 22 is less than the distance from the top surface of the connecting post 21 to the bottom of the first through groove 11. When it is necessary to loosen the screw terminal 22 to disconnect the wire connection, the user rotates the screw terminal 22, causing it to move upwards along the threads of the connecting post 21. Because the height of the vertical section 222 is less than the distance from the top surface of the connecting post 21 to the bottom of the first through groove 11, when the screw terminal 22 is completely unscrewed from the connecting post 21, its top remains below the top surface of the connecting post 21 and does not touch the first through groove 11. This prevents the screw terminal 22 from coming off.
[0051] The implementation method of Example 4 is as follows:
[0052] The difference between Embodiment 4 and Embodiment 1 is that the second through slot 12 is provided with a stop 14. The stop 14 needs to be removed when wiring the touch panel switch for the first time. The design of the stop 14 effectively prevents dust and foreign objects from entering the area where the connecting post 21 is located before wiring, thus protecting the cleanliness of the inside of the device.
[0053] The implementation method of Example 5 is as follows:
[0054] The difference between Embodiment 5 and Embodiment 1 is that the top of the screw terminal 22 has a first groove 223 and a second groove 224. The second groove 224 intersects the first groove 223 perpendicularly, and both ends of the second groove 224 extend to the two side edges of the screw terminal 22. When tightening the screw terminal 22, the user can insert a screwdriver into the first groove 223 or the second groove 224. The user can insert the screwdriver into the groove from different directions to better rotate the screw terminal 22. The first groove 223 and the second groove 224 intersect perpendicularly, forming a cross-shaped structure. The user can tighten the screw terminal 22 using a flathead or Phillips head screwdriver. The fact that both ends of the second groove 224 extend to the two side edges of the screw terminal 22 means that when using a flathead screwdriver to tighten the screw terminal 22, even if the width of the flathead screwdriver is greater than the length of the second groove 224, it can still be smoothly inserted and engaged in the second groove 224, providing high flexibility.
[0055] Specifically, the working principle of this utility model is as follows:
[0056] The touch panel switch includes a back cover 1, a circuit board 2, a connecting post 21, and a screw terminal 22. The connecting post 21 is mounted on the circuit board 2, and the screw terminal 22 is fixed inside the connecting post 21 by a threaded connection. A first through slot 11 is provided on one side of the back cover 1. The through slot is crescent-shaped when viewed from above, and its shortest diameter is smaller than the top diameter of the screw terminal 22, ensuring that the screw terminal 22 cannot pass through the first through slot 11 at any rotation angle, thereby preventing it from coming out. The height design of the vertical section 222 ensures that when the screw terminal 22 is screwed out, its top just reaches the bottom of the first through slot 11, preventing the screw terminal 22 from continuing to rise and damaging the first through slot 11.
[0057] The chamfered section 221 makes the screw terminal 22 easier to align and operate during installation and removal, and prevents it from completely dislodging from the connecting post 21. The top edge of the screw terminal 22 is rounded, reducing wear or scratches on the first through groove 11. A second through groove 12 is also provided on one side of the rear cover 1, and a groove 211 is provided on one side of the connecting post 21. The two are connected, allowing the wire to be smoothly inserted into the connecting post 21. The frame 13 is provided with several chambers, and the connecting post 21 is installed in these chambers, which enhances the rigidity around the first through groove 11 and prevents deformation or damage during long-term use.
[0058] When connecting the wire, the user inserts the wire through the second through slot 12 into the slot 211 within the connecting post 21, and then tightens the wire by rotating the screw terminal 22. To disconnect the wire, the user rotates the screw terminal 22 in the opposite direction, causing it to move upwards along the thread of the connecting post 21 until the top of the screw terminal 22 contacts the bottom end of the first through slot 11. At this point, the threaded connection between the screw terminal 22 and the connecting post 21 is released.
[0059] In summary, this utility model solves the problem that the screw terminals of traditional control switches are prone to falling off.
