[0038] When installing electrical switches on a wall, the mounting box 100 is typically pre-embedded in the wall. Then, the main circuit wires are connected to the electrical device. After wiring, the electrical device 101 is screwed into the mounting box 100. A screwdriver is required for wiring and screw assembly. Since the main circuit wires are still energized at this time, the wiring process poses a safety hazard. This installation process is not only cumbersome but also highly dangerous. Furthermore, during maintenance and replacement, the electrical device 101 cannot be quickly disassembled.

[0039] To address the aforementioned technical problems, embodiments of this application provide a magnetic module and an electrical switch.

[0040] Reference Figure 1 , Figure 2As shown, this application embodiment provides a magnetic module for connecting a mounting box 100 and an electrical device 101. The magnetic module includes a magnetic frame 102; the mounting box 100 has a first attraction surface 103, and the electrical device 101 has a second attraction surface 104; a first magnetic block 105 is provided on the side of the magnetic frame 102 near the first attraction surface 103; a first switch button 106 for controlling the main circuit is provided on the first attraction surface 103 or the magnetic frame 102; the first magnetic block 105 generates a force to make the magnetic frame 102 abut against the first attraction surface 103, and pressing the first switch button 106 will cut off the power to the main circuit.

[0041] A second magnetic block 107 is provided on the side of the magnetic frame 102 near the second contact surface 104. A second switch button 108 for controlling the main circuit is provided on the second contact surface 104 or the magnetic frame 102. The second magnetic block 107 generates a force to make the magnetic frame 102 abut against the second contact surface 104, and pressing the second switch button 108 will turn on the main circuit.

[0042] The magnetic module provided in this application embodiment is configured in the mounting box 100 for connecting the electrical device 101. The magnetic module includes a magnetic frame 102; the mounting box 100 has a first attraction surface 103, and the electrical device 101 has a second attraction surface 104.

[0043] It should be noted that the electrical device 101 in the embodiments of this application can be a temperature electrical device 101 or other electrical devices 101, and there is no special limitation on it.

[0044] It should be noted that, in this embodiment of the application, the magnetic frame 102 is installed inside the mounting box 100, with one side close to the first attraction surface 103 and the other side close to the second attraction surface 104 of the electrical device 101. That is to say, the magnetic frame 102 is located between the first attraction surface 103 and the second attraction surface 104.

[0045] Reference Figure 1 , Figure 2 As shown, in this embodiment of the application, the magnetic frame 102 is provided with a first magnetic block 105 and a first switch button 106 for controlling the main circuit on the side near the first contact surface 103. The first magnetic block 105 generates a force that causes the magnetic frame 102 to abut against the first contact surface 103, and the first contact surface 103 presses the first switch button 106 to cut off the power to the main circuit.

[0046] In this embodiment, the first magnetic block 105 attracts the magnetic frame 102 and the first attraction surface 103 together. At the same time as the magnetic connection is achieved, the first switch button 106 cuts off the power to the main circuit, thereby cutting off the power to the wires led out from the main circuit. Workers can wire the electrical device 101 when the main circuit is de-energized, which can greatly improve the safety of the wiring process.

[0047] In this embodiment of the application, a second magnetic block 107 is provided on the side of the magnetic frame 102 near the second attraction surface 104. A second switch button 108 for controlling the main circuit is provided on the second attraction surface 104. The second magnetic block 107 generates a force that causes the magnetic frame 102 to abut against the second attraction surface 104. The magnetic frame 102 presses the second switch button 108 to power on the main circuit.

[0048] It should be noted that after the wiring is completed, in this embodiment, the magnetic frame 102 and the second contact surface 104 are attracted by the second magnetic block 107, and the second switch button 108 is pressed at the same time as the magnetic connection is achieved, so that the main circuit is powered on. Compared with the prior art, this embodiment can not only realize power-off wiring and improve the safety of the wiring process, but also improve the convenience of installation and disassembly through magnetic connection, making it easier for staff to quickly assemble and disassemble.

[0049] Reference Figure 1 , Figure 2 As shown, as an optional implementation, the mounting box 100 is provided with a first guide groove 109, the extension direction of the first guide groove 109 is perpendicular to the first suction surface 103; the magnetic frame 102 is provided with a first guide strip 110, the first guide strip 110 is inserted into the first guide groove 109.

[0050] It should be noted that, in this embodiment of the application, a first guide groove 109 is provided inside the mounting box 100, and a first guide strip 110 is provided on the magnetic frame 102. The first guide groove 109 and the first guide strip 110 are inserted and engaged to form a sliding guide structure 217. Therefore, the magnetic frame 102 can move closer to or further away from the first attraction surface 103 along the first guide groove 109.

[0051] The magnetic force generated by the first magnetic block 105 enables the magnetic frame 102 to approach the first attraction surface 103 along the first guide groove 109.

[0052] It should be noted that, referring to Figure 2 , Figure 3 As shown, the first contact surface 103 of the mounting box 100 has a first groove 113, and the mounting box magnet 114 is embedded in the first groove 113; the mounting box magnet 114 and the projection of the first magnet 105 on the first contact surface 103 coincide.

[0053] The first magnetic block 105 can attract the mounting box magnetic block 114, thereby causing the magnetic frame 102 to abut against the first attraction surface 103. At this time, the first guide groove 109 not only provides a guiding function, but also provides an alignment function for the first magnetic block 105 and the mounting box magnetic block 114, ensuring that the first magnetic block 105 and the mounting box magnetic block 114 can be accurately attracted.

[0054] Reference Figure 1 , Figure 2 As shown, as an optional implementation, the magnetic frame 102 is provided with a second guide groove 111, the extension direction of the second guide groove 111 is perpendicular to the first attraction surface 103; the electrical device 101 is provided with a second guide bar 112, the second guide bar 112 is inserted into the second guide groove 111.

[0055] In this embodiment, a second guide groove 111 is provided on the magnetic frame 102, and a second guide bar 112 is provided on the electrical device 101. The second guide groove 111 and the second guide bar 112 are inserted and engaged to form a sliding guide structure 217. Therefore, the electrical device 101 can move closer to or further away from the first attraction surface 103 along the first guide groove 109.

[0056] The magnetic force generated by the second magnetic block 107 enables the electrical device 101 to approach the magnetic frame 102 along the second guide groove 111.

[0057] It should be noted that, referring to Figure 1 , Figure 4 As shown, the second contact surface 104 of the electrical device 101 has a second groove 115, and the electrical device magnetic block 116 is embedded in the second groove 115; the projection of the electrical device magnetic block 116 and the second magnetic block 107 on the second contact surface 104 coincides.

[0058] The second magnetic block 107 can attract the electrical device magnetic block 116, thereby causing the magnetic frame 102 to abut against the second attraction surface 104. At this time, the second guide groove 111 not only provides a guiding function, but also provides an alignment function for the second magnetic block 107 and the electrical device magnetic block 116, ensuring that the second magnetic block 107 and the electrical device magnetic block 116 can be accurately attracted.

[0059] It should be noted that multiple sets of the first guide groove 109, the second guide groove 111, the first guide bar 110, and the second guide bar 112 can be provided, and the specific structure can be set by those skilled in the art as needed, without any special limitation.

[0060] Reference Figure 1 As shown, in one optional implementation, when the magnetic frame 102 abuts against the first contact surface 103, the mounting box 100 and the magnetic frame 102 are connected by the first snap fastener 117; when the magnetic frame 102 abuts against the second contact surface 104, the electrical device 101 and the magnetic frame 102 are connected by the second snap fastener 118.

[0061] It should be noted that while the magnetic frame 102 abuts against the first abutting surface 103, the mounting box 100 and the magnetic frame 102 can be engaged to prevent the magnetic frame 102 from being improperly installed. Specifically, the first latch 117 can be disposed on the magnetic frame 102, and a hook-on portion cooperating with the first latch 117 can be formed on the mounting box 100. Alternatively, the first latch 117 can be disposed on the mounting box 100, and a hook-on portion cooperating with the first latch 117 can be formed on the magnetic frame 102.

[0062] It should be noted that while the magnetic frame 102 abuts against the second suction surface 104, the electrical device 101 and the magnetic frame 102 can be engaged to prevent the magnetic frame 102 from being improperly installed. Specifically, the second latch 118 can be disposed on the magnetic frame 102, with a hook-on portion formed on the electrical device 101 that mates with the second latch 118. Alternatively, the second latch 118 can be disposed on the electrical device 101, with a hook-on portion formed on the magnetic frame 102 that mates with the second latch 118.

[0063] The specific structure of the first buckle 117 and the second buckle 118 can be a hook or other shape, which can be set by those skilled in the art as needed.

[0064] It should be noted that the connection in this embodiment is achieved through magnetic attraction. The first buckle 117 and the second buckle 118 can be used as a backup fixing structure or as a secondary fixing and reinforcing structure to avoid the problem of the magnetic frame 102 not being able to hold firmly, and effectively improve the reliability of the structure.

[0065] Reference Figure 4 As shown, as an optional implementation, the electrical device 101 has a rear cover 119, and the rear cover 119 is provided with a quick-connection mechanism on the side near the magnetic frame 102 for connecting to the wires led out from the main circuit.

[0066] Reference Figure 5 As shown, the quick wiring mechanism includes a wiring button 120 and a V-shaped conductive bridge 121. The wiring button 120 is slidably mounted on the rear cover 119. The first side 122 of the V-shaped conductive bridge 121 is electrically connected to the PCB board disposed inside the rear cover 119. When the wiring button 120 is driven, it pushes the second side 123 of the V-shaped conductive bridge 121 to move towards the first side 122, so that the wiring port provided on the wiring button 120 is connected to the wiring socket opened on the rear cover 119 for inserting the wires of the main circuit.

[0067] The rear cover 119 is provided with a spring element 124 connected to the wiring button 120. The spring element 124 generates a force that pushes the wiring button 120 away from the V-shaped conductive bridge 121.

[0068] It should be noted that the quick-connect mechanism can be set on the back cover, or it can be soldered as a whole to the PCB board set in the electrical device 101, and then the back cover is fastened to the main body of the electrical device 101.

[0069] The PCB board has a wiring board, and the V-shaped conductive bridge 121 abuts against the wiring board.

[0070] The quick-connection button 120 provided in this application embodiment does not require screw wiring; wiring can be achieved simply by pressing the button, making it convenient for staff to perform quick disassembly and maintenance.

[0071] During wiring, the operator presses the wiring button 120, compressing the spring element 124. The button 120 then pushes the second side 123 of the V-shaped conductive bridge 121 towards the first side 122. Since the wiring port on the button 120 connects with the wiring socket on the rear cover 119, a guide insertion channel is formed. Wires from the main circuit can be inserted through the wiring socket. At this point, the operator releases the pressing force, and the wiring button 120, pushed by the spring element 124, moves away from the V-shaped conductive bridge 121.

[0072] It should be noted that the V-shaped conductive bridge 121 has a certain elastic force. When the operator does not press the wiring button 120, the V-shaped conductive bridge 121 is not pressed by the wiring button 120. Under the action of the elastic restoring force, the second side 123 of the V-shaped conductive bridge 121 moves away from the first side 122 and abuts against the wire inserted from the wiring socket. At this time, the second side 123 abuts against the wire, and the first side 122 abuts against the terminal block on the electrical device 101, so as to realize the electrical connection between the wire and the electrical device 101.

[0073] Furthermore, a button limiting part is provided on the back cover 119, and a button latch is provided on the wiring button 120; when the button latch abuts against the button limiting part, it forms a blocking force that blocks the wiring button 120.

[0074] It should be noted that the blocking force formed when the button latch abuts against the button limiting part is in the opposite direction to the thrust of the spring element 124, and is used to limit the movement stroke of the wiring button 120.

[0075] Reference Figure 6 , Figure 7 As shown, the magnetic frame 102 of this application embodiment includes a first frame 203, a second frame 204, and an adjustment mechanism 205 connecting the first frame 203 and the second frame 204. The adjustment mechanism 205 is driven to make the first frame 203 and the second frame 204 move closer or further apart.

[0076] It should be noted that the plane containing the first frame 203 is parallel to the plane containing the second frame 204. The adjustment mechanism 205 of this embodiment can adjust the distance between the plane containing the first frame 203 and the plane containing the second frame 204. Specifically, the adjustment mechanism 205 can be driven to move the first frame 203 and the second frame 204 closer together or further apart.

[0077] Among them, reference Figure 8 , Figure 9 As shown, the adjustment mechanism 205 includes a rack 208 and an adjusting member 209; one end of the rack 208 is disposed on the second frame 204, and the other end is close to the first frame 203 and extends in a direction perpendicular to the plane of the first frame 203; the adjusting member 209 is rotatably disposed on the first frame 203, and the adjusting member 209 is provided with ratchet 210; when the adjusting member 209 is driven, the ratchet 210 engages with the rack 208, generating a force that prevents the first frame 203 from approaching the second frame 204.

[0078] It should be noted that the adjustment mechanism 205 in this embodiment includes a rack 208 and an adjustment member 209. The adjustment member 209 is rotatably mounted on the first frame 203, and the adjustment member 209 is provided with ratchet 210 that can mesh with the rack 208. When the ratchet 210 meshes with the rack 208, it can restrict the first frame 203 and the second frame 204 from getting close to each other. When the first frame 203 and the second frame 204 are driven away from each other, the ratchet 210 can move on the rack 208, so that the adjustment member 209 and the rack 208 can move relative to each other.

[0079] In other words, in this embodiment, the ratchet 210 of the adjusting member 209 engages with the rack 208, generating a force that only prevents the first frame 203 and the second frame 204 from approaching, but does not affect the mutual separation of the first frame 203 and the second frame 204, thus creating a unidirectional movement restriction between the first frame 203 and the second frame 204. When the distance between the mounting box 100 and the electrical device 101 is large, matching installation is achieved by separating the first frame 203 and the second frame 204.

[0080] Unlike the above embodiments, one end of the rack 208 is disposed on the first frame 203, and the other end is close to the second frame 204 and extends in a direction perpendicular to the plane of the second frame 204; the adjusting member 209 is rotatably disposed on the second frame 204.

[0081] It should be noted that, as needed, those skilled in the art can combine or set up the above two implementation methods separately.

[0082] Reference Figure 9 , Figure 10 , Figure 11As shown, as an optional implementation, the adjustment mechanism 205 further includes a spring element 211; the spring element 211 is disposed on the first frame 203 and connected to the adjustment member 209, and the spring element 211 generates a force that moves the ratchet 210 closer to the rack 208.

[0083] The adjustment mechanism 205 of this application embodiment can push the adjustment member 209 to move toward the rack 208 by the elastic force generated by the spring element 211, so that the ratchet 210 on the adjustment member 209 and the rack 208 are kept in a meshing state.

[0084] The embodiment of this application can ensure a stable meshing connection between the ratchet 210 and the rack 208 by setting the spring element 211. Especially when the first frame 203 and the second frame 204 move away from each other, after the ratchet 210 and the rack 208 slide relative to each other, the elastic force generated by the spring element 211 can push the ratchet 210 and the rack 208 to continue to enter the meshing state.

[0085] Reference Figure 8 As shown, as an optional implementation, the adjustment mechanism 205 further includes a limiting member 212; one end of the limiting member 212 is connected to the first frame 203, and the other end is provided with a supporting part 213; when the ratchet 210 meshes with the rack 208, the supporting part 213 abuts against the adjustment member 209 to generate a force that prevents the ratchet 210 from separating from the rack 208.

[0086] Furthermore, the adjustment mechanism 205 in this embodiment of the application can lock the adjustment member 209 by setting the limiting member 212, so as to prevent the ratchet 210 on the adjustment member 209 from separating from the rack 208.

[0087] In this embodiment, the limiting member 212 is connected to the first frame 203 at one end, and the abutting part 213 is provided at the other end. The abutting part 213 abuts against the adjusting member 209 to limit the adjusting member 209.

[0088] It should be noted that, referring to Figure 8 As shown, a cylindrical boss 218 can be provided on the adjusting member 209. The axis of the cylindrical boss extends in the same direction as the rotation axis of the adjusting member 209. The supporting part 213 abuts against the arc side of the cylindrical boss 218 to prevent the ratchet 210 on the adjusting member 209 from separating from the rack 208.

[0089] Furthermore, refer to Figure 9 , Figure 10As shown, the rack 208 has an end separation tooth 214 near the end of the first frame 203. The tooth height of the end separation tooth 214 is greater than the meshing tooth on the rack 208 that engages with the ratchet 210. The first frame 203 is driven away from the second frame 204. The end separation tooth 214 pushes the adjusting member 209 away from the rack 208. The supporting part 213 and the adjusting member 209 are relatively displaced. The supporting part 213 is provided with a hook 215. The hook 215 hooks the adjusting member 209 and generates a force that prevents the adjusting member 209 from rotating to one side of the rack 208.

[0090] It should be noted that the staff can manually pull apart the first frame 203 and the second frame 204. When the first frame 203 and the second frame 204 are far apart, since the tooth height of the end separating tooth 214 is greater than that of the other teeth on the rack 208, the end separating tooth 214 can push the adjusting member 209 to rotate away from the rack 208 through the tooth tip.

[0091] At this time, the adjusting member 209 rotates in an arc shape, and the cylindrical boss 218 provided on the adjusting member 209 also rotates together with the adjusting member 209. Specifically, the cylindrical boss 218 rotates from the side that abuts against the supporting part 213 to the side where the hook 215 is provided, so that the hook 215 of the supporting part 213 hooks onto the cylindrical boss 218. In this state, the spring element 211 is compressed and stores elastic potential energy, and the adjusting member 209 is completely separated from the rack 208.

[0092] It should be noted that the rack 208 is completely separated from the adjusting member 209, so there is no force that prevents the first frame 203 and the second frame 204 from moving closer to each other.

[0093] Furthermore, refer to Figure 11 As shown, the second frame 204 is provided with an unlocking boss 216 extending toward one side of the first frame 203; the first frame 203 and the second frame 204 are close to each other, and the unlocking boss 216 pushes the hook 215 to separate from the adjusting member 209.

[0094] Since the first frame 203 and the electrical device 101 can be magnetically connected, and the second frame 204 and the mounting box 100 can be magnetically connected, the operator can hold the electrical device 101 and place it into the mounting box 100. At this time, the first frame 203 and the second frame 204 will approach each other. When the first frame 203 and the second frame 204 approach each other to a certain position, the unlocking boss 216 pushes the limiting member 212, causing the hook 215 to separate from the cylindrical boss 218 on the adjusting member 209, allowing the spring element 211 to release its elastic potential energy, thereby causing the ratchet 210 to contact and engage with the rack 208. The operator can pull the electrical device outward to move the first frame 203 and the second frame 204 away from each other, thus adjusting the distance between them.

[0095] It should be noted that when the unlocking boss 216 abuts against the limiting member 212 in this embodiment of the application, it is the minimum distance between the first frame 203 and the second frame 204. The distance from which the unlocking boss 216 protrudes from the second frame 204 can be set by those skilled in the art as needed, and no special limitation is made in this regard.

[0096] It should be noted that the cylindrical boss 218 provided on the adjusting member 209 can be a boss of other shapes.

[0097] The limiting member 212 in this embodiment can be rotatably mounted on the first frame 203. Furthermore, the first frame 203 is provided with a boss that constrains the rotation range of the limiting member 212, ensuring that the abutment portion 213 of the limiting member 212 can effectively abut or engage with the adjusting member 209. Alternatively, the limiting member 212 can be configured as a metal spring, with one end fixed to the first frame 203 and the other end having the abutment portion 213.

[0098] Based on the above implementation method, in use, the second frame 204 can be magnetically connected to the mounting box 100 first, and then the first frame 203 can be placed into the mounting box 100 and pushed close to the second frame 204 until the unlocking boss 216 triggers the limiting member 212, so that the ratchet 210 and the rack 208 are engaged. At this time, the electrical device 101 is installed in place. Since the electrical device 101 and the first frame 203 are magnetically connected, the first frame 203 moves away from the second frame 204 towards the electrical device 101, realizing adaptive spacing adjustment.

[0099] Another installation method involves placing the first frame 203 and the second frame 204 together into the mounting box 100. The second frame 204 is magnetically connected to the mounting box 100 via a second magnet. The worker can adjust the distance between the two frames by pulling the first frame 203 away from the second frame 204. After adjusting the distance, the electrical device 101 is installed, with the first frame 203 connected to the electrical device 101 via the magnet.

[0100] It should be noted that the electrical device 101 in this application embodiment can be a temperature control module or an electrical device with other functions.

[0101] This application provides an electrical switch, including a mounting box 100, an electrical device 101, and the aforementioned magnetic module; the magnetic module is disposed in the mounting box 100 for connecting the electrical device 101, and the main circuit is electrically connected to the electrical device 101.

[0102] The electrical switch provided in this application embodiment uses the aforementioned magnetic module, which can achieve magnetic connection with the mounting box 100 and the electrical device 101. The main circuit can be de-energized by the first switch button 106. Therefore, the electrical switch provided in this application embodiment is not only easy to install and remove, improving the convenience of operation, but also prevents live wiring, greatly improving the safety of the operation process.

[0103] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
