Description

Technical Field

[0001] This application relates to the field of electrical switch technology, and in particular to an intelligent electrical switch that is easy to wire. Background Technology

[0002] Electrical switches are widely used in various power systems to control the on / off state of circuits. Currently, common electrical switches on the market mainly include traditional manual switches and modern intelligent switches. While traditional manual switches are simple in structure and inexpensive, they have significant shortcomings in terms of intelligence and convenience. Modern intelligent switches, by integrating advanced technologies such as sensors and microprocessors, achieve functions such as remote control and automatic detection, greatly improving the user experience.

[0003] However, existing smart electrical switches generally achieve wiring by soldering copper leads for insertion, which is not very convenient when it is necessary to actively use cables for wiring, such as using terminal blocks. Utility Model Content

[0004] This application provides an intelligent electrical switch that is easy to wire, in order to solve the problem that current intelligent electrical switches are difficult to wire with cables.

[0005] An easy-to-wire smart electrical switch includes:

[0006] The outer shell is hollow inside;

[0007] A contact module is disposed inside the housing. The contact module includes a plurality of first connectors and a plurality of second connectors. The first connectors are electrically connected to external devices, and the second connectors are electrically connected to terminals.

[0008] A control module is located inside the housing, and the control module is capable of controlling the first connector and the corresponding second connector to be connected or disconnected;

[0009] A circuit board is disposed inside the housing and is electrically connected to the control module.

[0010] By adopting the above technical solution, the outer casing provides protection for the internal structure, the first connector can be electrically connected to external devices, and the second connector can be directly electrically connected to a terminal block with a connector or cable, or it can be connected to a terminal block first, and then the terminal block can be electrically connected to other connectors. This enables the switch to be wired to different electrical devices and control their on / off states, thus expanding its application scenarios.

[0011] In one embodiment, the contact module includes a base, the housing covers the base, the first connector and the second connector are both disposed on the base, one end of the first connector extends downward through the base, and the second connector is screwed to the terminal block on the base.

[0012] By adopting the above technical solution, the second connector is screwed and fixed to the terminal block, which not only maintains the conductivity and makes the wiring more stable, but also facilitates the installation and disassembly of the terminal block; in addition, different types of terminal blocks can be replaced according to different scenarios.

[0013] In one embodiment, the base includes a connecting seat, one end of each of the second connectors is disposed on the connecting seat, the connecting seat includes a fixing groove and a second baffle, the fixing groove is disposed at the upper end of the connecting seat and is recessed downward, the fixing groove corresponds one-to-one with the second connector, the second baffle is disposed on both sides of the fixing groove, and bolts are disposed in the fixing groove to fix the second connector and the terminal block.

[0014] By adopting the above technical solution, the second baffle isolates the connection between the second connector and the terminal block, and most of the bolts are located in the fixing groove. This structure further prevents electrical interference, ensures the electrical insulation performance between components, improves the electrical performance and safety reliability of the switch, and also facilitates the fixing and installation of the terminal blocks.

[0015] In one embodiment, the contact module further includes a current transformer assembly disposed on the base and electrically connected to the circuit board, and the second connector passes through the current transformer assembly and is connected to the connection terminal.

[0016] By adopting the above technical solution, when the first and second connectors are connected, the current transformer assembly can detect the current flowing through the second connector and transmit it to the circuit board. When the current is outside the preset range, the circuit board powers on the control module to disconnect the first and second connectors. This function enables real-time monitoring and protection of the circuit current, preventing damage to the circuit and equipment due to overcurrent or other abnormal conditions, and improving the safety and reliability of the switch.

[0017] In one embodiment, the current transformer assembly includes a current transformer and a housing, the housing being disposed at the upper end of the base, the current transformer being disposed inside the housing, a second connector passing through the current transformer, and the housing also having a first baffle disposed between the second connectors.

[0018] By adopting the above technical solution, this design effectively prevents electrical interference between the second connectors, improves the accuracy of the current detection by the transformer, and also enhances the stability and safety of the internal electrical structure of the switch.

[0019] In one embodiment, the contact module further includes a conductive component disposed on the base and extending along the length direction of the base, the first connector and the second connector being disposed on both sides of the conductive component along the width direction, and the control module being able to control the movement of the conductive component.

[0020] By adopting the above technical solution, the conducting component moves along the length direction to achieve simultaneous conduction or separation between both ends and the first and second connecting parts, thereby enabling conduction or separation between the first and second connecting parts. This mechanical structure design is simple and reliable, can effectively realize the on / off control of the circuit, and is easy to automate.

[0021] In one embodiment, the conductive assembly includes a moving contact link, a conductive element, and a pushing element. The control module is connected to the moving contact link. The conductive element is located at the lower end of the moving contact link and extends in the width direction. Both ends of the conductive element are respectively connected to the first connecting element and the second connecting element. The pushing element is located at the upper end of the moving contact link.

[0022] By adopting the above technical solution, under the action of the control module, the moving contact linkage can drive the conductive and pushing components to move, thereby enabling the first connecting component to be connected or separated from the second connecting component through the conductive component, ensuring the working accuracy and reliability of the switch.

[0023] In one embodiment, the control module includes a coil, a rotating component, and a first magnetic conductive component. The circuit board is electrically connected to the coil. The rotating component is located at the lower end of the coil. The first magnetic conductive component is located on both sides of the rotating component. The rotating component is connected to the moving contact linkage.

[0024] By adopting the above technical solution, the circuit board applies both a conduction voltage and a separation voltage to the coil, causing the first magnetic component to drive the rotating component to rotate, thereby moving the moving contact linkage. This electromagnetic control method can precisely control the action of the conducting component, achieving fast and accurate on / off control of the circuit, and improving the switch's response speed and control accuracy.

[0025] In one embodiment, the easy-to-wire smart electrical switch further includes a first elastic element and an inner shell. The inner shell surrounds the control module and is fixed to the base. The inner shell is provided with a receiving groove. The first elastic element and the pushing element are both disposed in the receiving groove, and the pushing element can abut against the first elastic element.

[0026] By adopting the above technical solution, the first elastic element provides assistance to the pushing element when the first and second connecting elements are ready to conduct, thereby reducing the voltage and power required for the coil to rotate the rotating element. This not only reduces the energy consumption of the switch but also reduces costs, meeting customers' needs for low power.

[0027] In one embodiment, the circuit board is disposed on the base and extends upward to be fixed to the inner shell, the circuit board is provided with a clearance hole, and the receiving groove passes through the clearance hole.

[0028] By adopting the above technical solution, the vertically arranged circuit board is more compactly connected with the control module and contact module, and occupies less space overall. This is conducive to the miniaturization design of the switch and makes the internal structure more reasonable, which is convenient for installation and maintenance.

[0029] In summary, this application includes at least one beneficial effect:

[0030] 1. The housing provides protection for the internal structure. The first connector can be electrically connected to external devices. The second connector can be directly electrically connected to a terminal block with a connector or cable, or it can be connected to a terminal block first, and then the terminal block can be electrically connected to other connectors. This enables the switch to be wired to different electrical devices and control their on / off states, thus expanding its application scenarios.

[0031] 2. When the first and second connectors are connected, the current transformer assembly can detect the current flowing through the second connector and transmit it to the circuit board. When the current is outside the preset range, the circuit board powers on the control module to disconnect the first and second connectors. This function enables real-time monitoring and protection of the circuit current, preventing damage to the circuit and equipment due to overcurrent or other abnormal conditions, and improving the safety and reliability of the switch.

[0032] 3.

[0039] The following is in conjunction with the appendix Figure 1-5 The present application provides a further detailed description of the intelligent electrical switch that facilitates wiring.

[0040] Example 1

[0041] Please see Figure 1-5 The present application provides an intelligent electrical switch 1 that is easy to wire, including a housing 11, a contact module 12, a control module 13 and a circuit board 14.

[0042] like Figures 1 to 3As shown, the housing 11 is hollow inside, and the contact module 12 is disposed inside the housing 11. The contact module 12 includes multiple first connectors 121 and multiple second connectors 122. The first connectors 121 can be electrically connected to external devices, and the second connectors 122 can be electrically connected to terminals 125. Specifically, the contact module 12 also includes a base 123, which is covered by the housing 11. The first connectors 121 and the second connectors 122 are both disposed on the base 123. One end of the first connector 121 extends downward through the base 123, and the second connector 122 is screwed to the terminal 125 on the base 123. In this embodiment, the base 123 includes a connecting seat 1231. One end of each second connector 122 is disposed on the connecting seat 1231. The connecting seat 1231 includes a fixing groove 1232 and a second baffle 1233. The fixing groove 1232 is located at the upper end of the connecting seat 1231 and is recessed downward. The second connector 122 is provided with positioning holes, which correspond one-to-one with the fixing groove 1232. The second baffle 1233 is disposed on both sides of each fixing groove 1232. Bolts pass through the positioning holes and are disposed in the receiving groove 161 to fix the second connector 122 and the terminal block 125. In this way, not only can a stable connection between each second connector 122 and the terminal block 125 be guaranteed, but the terminal block 125 can also be easily disassembled, making it suitable for different scenarios. In addition, it can also effectively prevent mutual interference between them.

[0043] Furthermore, the circuit board 14 is also located inside the housing 11. The contact module 12 also includes a current transformer assembly 124, which is located on the base 123 and electrically connected to the circuit board 14. The second connector 122 passes through the current transformer assembly 124 and is connected to the terminal block 125. Specifically, the current transformer assembly 124 includes a current transformer 1241 and a housing 1242. The housing 1242 is located at the upper end of the base 123, and the current transformer 1241 is located inside the housing 1242. The upper end of the housing 1242 is also provided with a plurality of first baffles 1243, which are located between the second connectors 122, and also serve to isolate the second connectors 122 to prevent short circuits or other interference between adjacent second connectors 122.

[0044] The contact module 12 also includes a conductive component 126, which is disposed on the base 123 and extends along the length of the base 123. A first connector 121 and a second connector 122 are respectively disposed on both sides of the conductive component 126 along the width of the base 123. This design greatly simplifies the operation of the electrical switch and improves ease of use and safety.

[0045] Specifically, the conductive assembly 126 includes a moving contact link 1261, a conductive element 1262, and a pushing element 1263. The control module 13 is connected to the moving contact link 1261. The conductive element 1262 is located at the lower end of the moving contact link 1261 and extends in the width direction, allowing both ends of the conductive element 1262 to conduct to the first connecting element 121 and the second connecting element 122, respectively. The pushing element 1263 is located at the upper end of the moving contact link 1261. Through the action of the control module 13, the moving contact link 1261 can move horizontally along its length, thereby causing both ends of the conductive element 1262 to contact or separate from the first connecting element 121 and the second connecting element 122, respectively. In this embodiment, each second connector 122 may include a first segment 1221 and a second segment 1222. One end of the first segment 1221 is connected to the corresponding conductor 1262, and the other end extends along the width direction, then bends and vertically upwards to pass through the current transformer 1241 and the housing 1242. One end of the second segment 1222 is fitted onto the first segment 1221 and then extends horizontally along the width direction to the fixing groove 1232 of the connector 1231. The second segments 1222 are isolated from each other by the first baffle 1243 and the second baffle 1233. Finally, the other end of the second segment 1222 is electrically connected to the terminal block 125 by bolts.

[0046] like Figures 4 to 5 As shown, the control module 13 is located inside the housing 11 and can control the first connector 121 and its corresponding second connector 122 to be connected or disconnected. The circuit board 14 is electrically connected to the control module 13. Specifically, the control module 13 includes a coil 131, a rotating component 132, and a first magnetic conductor 133. The circuit board 14 is electrically connected to the coil 131. The two ends of the coil 131 are also connected to second magnetic conductors 134. The rotating component 132 is located at the lower end of the coil 131 and has a permanent magnet inside. The first magnetic conductors 133 are located on both sides of the rotating component 132 and are connected to the permanent magnet. The rotating component 132 is connected to the moving contact connecting rod 1261. In this embodiment, two first magnetic conductors 133 are provided on both sides of the rotating component 132, and the magnetic poles of the two first magnetic conductors 133 located in the same horizontal direction are the same.

[0047] The intelligent electrical switch may further include a first elastic element 15 and an inner shell 16. The inner shell 16 surrounds the control module 13 and is fixed to the base 123. A receiving groove 161 is provided at the lower end of the inner shell 16. The first elastic element 15 and the pushing element 1263 are both disposed within the receiving groove 161. The receiving groove 161 is also provided with a stop 162, which are spaced apart from each other. The pushing element 1263 can pass through the stop 162 and abut against the first elastic element 15. Specifically, the circuit board 14 is disposed on the base 123 and extends upward and is fixed to the inner shell 16. The circuit board 14 is provided with a clearance hole 141, and the receiving groove 161 is disposed within the clearance hole 141. Specifically, the circuit board 14 is disposed on the same side of the control module 13 and the current transformer assembly 124 and is spaced apart from the current transformer assembly 124. The electronic components on the circuit board 14 can be placed within this gap. This layout not only makes the entire electrical switch structure more compact but also saves space and is conducive to miniaturization design.

[0048] When the intelligent electrical switch remains in the ON state, coil 131 is not energized, the second magnetic element 134 is equivalent to iron, and the permanent magnet inside the rotating part 132 conducts the attraction force of the first magnetic element 133 located diagonally to the second magnetic element 134, so that the first magnetic element 133 and its corresponding second magnetic element 134 are attracted to each other. The first connector 121 and the second connector 122 are stably connected through the conductor 1262. The current transformer 1241 can detect the current flowing through the first section 1221 and transmit it to the circuit board 14. The circuit board 14 decides whether to connect the separation voltage to coil 131 according to the set current range, so that the first connector 121 and the second connector 122 are disconnected.

[0049] When the circuit board 14 detects that the current exceeds the set range, the circuit board 14 applies an instantaneous separation voltage to the coil 131. As a result, the second magnetic element 134 generates a magnetic pole and repels the corresponding first magnetic element 133. The instantaneous repulsive force is greater than the attraction force of the first magnetic element 133 on the second magnetic element 134, so the rotating element 132 rotates, causing the pushing element 1263 to compress the first elastic element 15. At this time, the coil 131 is not energized, and the second magnetic element 134 is equivalent to iron. The two first magnetic elements 133 located on the other diagonal attract the corresponding second magnetic elements 134 respectively. The attraction force generated by them balances the reaction force of the first elastic element 15, and the separation state is maintained. When conduction is required, circuit board 14 applies a momentary conduction voltage to coil 131. The second magnetic element 134 generates a magnetic pole opposite to that at separation and repels the corresponding first magnetic element 133. Simultaneously, the reaction force of the first elastic element 15 is applied to the pushing element 1263, making the repulsive force and reaction force greater than the attraction force of the first magnetic element 133 on the second magnetic element 134. This causes the rotating element 132 to rotate until the first elastic element 15 abuts against the stop block 162. Subsequently, the attraction force of the first magnetic element 133 on the second magnetic element 134, which is different from the original force, is conducted through the permanent magnet, thus maintaining a stable conduction state and preventing disengagement. The first elastic element 15 can assist in the initial stage of the movement of the moving contact linkage 1261, thereby reducing the conduction voltage required for coil 131 to rotate the rotating element 132, and thus reducing power consumption.

[0050] The implementation principle of this embodiment is as follows: the second connector 122 is electrically connected to the terminal block 125 via bolts, allowing the terminal block 125 to be connected to other cables or connectors, thus expanding the application scenarios of the intelligent electrical switch and facilitating the installation, removal, and replacement of different types of terminal blocks 125. Simultaneously, the presence of the current transformer assembly 124 provides the electrical switch with self-protection capabilities, automatically disconnecting the circuit when the current exceeds a preset value, effectively preventing overload and short-circuit accidents. The overall structure is compact and easy to operate, requiring relatively low voltage and power, making it suitable for various complex electrical environments and significantly improving the functionality and reliability of the electrical switch.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
