[0034] Currently, the commonly used intelligent switch mainly consists of a housing and a control module, an instrument transformer, and a contactor arranged inside the housing. A connector is provided on the circuit board of the control module, and the connector includes a plurality of connection terminals welded to the printed circuit board. The existing intelligent switches usually achieve remote control and automation functions by adding a wireless communication module to the switch or using an external intelligent controller. However, these solutions usually lead to the problem of complex installation of the intelligent switch.
[0035] To solve the above problems, please refer to Figures 1 to 5 , the present utility model proposes an intelligent switch 100, which includes a mounting base 110 and a control module 120, an instrument transformer module 130, and a contactor module 140 arranged on the mounting base 110;
[0036] The instrument transformer module 130 includes an instrument transformer 131 and a copper bar assembly 132. The copper bar assembly 132 is passed through the instrument transformer 131. The instrument transformer 131 is used to detect the magnitude of the current on the copper bar assembly 132, and the copper bar assembly 132 is connected to the contactor module 140 in a switched-on and -off manner;
[0037] The control module 120 includes a circuit board 121, a first connector 122, and a second connector 124. The circuit board 121 has a mounting surface 1211. The first connector 122 and the second connector 124 are both disposed on the mounting surface 1211 and electrically connected to the circuit board 121. The current transformer module 130 and the contactor module 140 are arranged side by side on the mounting base 110 and on the same side of the mounting surface 1211. The current transformer module 130 is electrically connected to the first connector 122, and the contactor module 140 is electrically connected to the second connector 124.
[0038] In this embodiment, the circuit board 121 is mounted on the mounting base 110, and the first connector 122 and the second connector 124 are spaced apart along the length direction of the circuit board 121. The first connector 122 is electrically connected to the current transformer module 130, and the second connector 124 is electrically connected to the contactor module 140. This layout can optimize the internal wiring and connection method of the circuit board 121, ensuring the stable connection and normal operation of the contactor module 140 and the current transformer 131 with the circuit board 121. The utility model has a simple structure and is easy to install. By means of the current transformer module 130, accurate sensing of current can be achieved, automatic control of the circuit can be realized, and the convenience and efficiency of switch operation are improved.
[0039] It is worth mentioning that in one embodiment, the current transformer module 130 includes a residual current transformer, whose main function is to detect the residual current (ground fault current such as electric shock and leakage) of the main circuit passing through the current transformer, and convert the residual current of the primary circuit into the output voltage of the secondary circuit.
[0040] In the embodiment of the present utility model, please refer to Figure 2 and Figure 3 , the first connector 122 has a socket 122a. The first connector 122 includes a first terminal 123. The first terminal 123 has a plug-in section 1231 and a first bent section 1232. The plug-in section 1231 is located in the socket 122a and is used for electrical connection with the current transformer module 130. The first bent section 1232 passes out of the socket 122a and bends towards the mounting surface 1211. The first bent section 1232 is electrically connected to the circuit board 121.
[0041] In this embodiment, the bent section passes out from the side of the first connector 122 away from the notch of the insertion slot 122a, bends towards the direction close to the mounting surface 1211, and is electrically connected to the circuit board 121 by wires. That is, the bent section is not arranged to penetrate through the circuit board 121. Therefore, the second connector 124 can be directly soldered on the surface of the circuit board 121 through surface mount technology, which simplifies the production process and improves the production efficiency of the present utility model. In addition, the insertion section 1231 is located in the insertion slot 122a and is directly electrically connected to the mutual inductor module 130. This design ensures the stability and reliability of the connection, and avoids circuit interruption or failure caused by loosening or poor contact.
[0042] In an embodiment of the present utility model, please refer to Figure 2 and Figure 3 , the second connector 124 has a receiving slot 124a. The second connector 124 includes a second terminal 125. The second terminal 125 includes a contact section 1251 and a second bent section 1252. The contact section 1251 is located in the receiving slot 124a. The second bent section 1252 extends out of the receiving slot 124a and bends towards the mounting surface 1211 and penetrates through the circuit board 121. The contactor module 140 includes a connection terminal. The connection terminal passes through the side of the second connector 124 away from the notch of the receiving slot 124a and abuts against the contact section 1251.
[0043] In this embodiment, the connection terminal of the contactor module 140 directly passes through the second connector 124 and abuts against the contact section 1251, reducing the contact resistance in the circuit and the possibility of connection failure, thereby improving the stability and reliability of the circuit. This abutting method avoids connection problems such as joint loosening, oxidation or poor insertion that may occur in the insertion method, and improves the long-term stability and maintainability of the circuit. Further, direct abutment can simplify the design and reduce the space requirement of the insertion components. Especially in the case of high-density wiring, it helps to optimize the layout and space utilization and is convenient for the installation of the present utility model.
[0044] It should be noted that, referring to Figure 1 and Figure 2 , when the present utility model is assembled, the contactor module 140 moves towards the circuit board 121. Two pins of the contactor coil in the contactor module 140 with the same setting direction as the contact section 1251 can directly pass through the side of the second connector 124 away from the notch of the receiving slot 124a and abut against the contact section 1251. Such a design method is convenient for circuit board repair and replacement and convenient for automatic assembly during mass production, so as to improve the production efficiency of the present utility model.
[0045] In an embodiment of the present utility model, the circuit board 121 has a first section 1212 and a second section 1213 along its length direction. The width of the second section 1213 is smaller than the width of the first section 1212. The first connector 122 and the second connector 124 are respectively disposed on the first section 1212 and the second section 1213.
[0046] In this embodiment, the width of the second section 1213 is smaller than the width of the first section 1212, enabling the housing of the contactor module 140 to be installed at both ends of the second end along the width direction, which can better adapt to the internal space limitation of the present utility model, maximize the utilization of the available space, and thus improve the compactness and integration degree of the present utility model.
[0047] In an embodiment of the present utility model, please refer to Figure 4 , the intelligent switch 100 further includes a housing 150. The housing 150 and the mounting base 110 enclose to form a receiving cavity 150a. The circuit board 121, the contactor module 140, and at least part of the current transformer module 130 are located in the receiving cavity 150a. A support protrusion 151 is provided in the housing 150 and extends along its width direction. The support protrusion 151 abuts against the side of the second section 1213 away from the mounting surface 1211.
[0048] In this embodiment, the support protrusion 151 extends along the width direction of the housing 150 and abuts against one side of the housing 150, increasing the stability and rigidity of the overall structure. This helps to prevent the control module 120 from moving or being damaged due to external impact or vibration during use. Further, the support protrusion 151 abuts against the side away from the mounting surface 1211, providing a stable support structure, which helps to maintain the stability and correct position of the switch during installation, simplifies the installation steps, and improves the installation efficiency.
[0049] In an embodiment of the present utility model, a clamping portion is provided at one end of the housing 150 along its length direction. One end or both ends of the first section 1212 along its width direction are clamped with the clamping portion to fix the circuit board 121 in the housing 150.
[0050] In an embodiment of the present utility model, please refer to Figure 4 and Figure 5 , the clamping portion includes two symmetrically arranged clamping protrusions 152. Both clamping protrusions 152 have a guiding section 1521 and a clamping section 1522. A guiding groove is formed between the two oppositely arranged guiding sections 1521, and a clamping groove is directly formed between the two oppositely arranged clamping sections 1522. At least part of the edge of the circuit board 121 is clamped in the clamping groove.
[0051] In this embodiment, through two symmetrically arranged clamping protrusions 152, each protrusion includes a guiding section 1521 and a clamping section 1522, ensuring that the circuit board 121 can be accurately positioned and aligned during installation. The design of the guiding section 1521 and the guiding groove enables the circuit board 121 to be conveniently slid into the correct position, while the clamping section 1522 and the clamping groove ensure that the circuit board 121 maintains a stable position after installation. The design of the clamping section 1522 can effectively fix the edge of the circuit board 121, preventing the circuit board 121 from moving or falling off due to vibration or other external forces during device operation. This stable installation ensures the reliability and safety of the circuit board 121. Since the circuit board 121 can be easily inserted and fixed in the clamping groove, when maintenance or replacement of the circuit board 121 is required, the operation is more convenient and efficient.
[0052] In an embodiment of the present utility model, please refer to Figure 2 and Figure 4 , the control module 120 further includes a third terminal 127 provided on the first section 1212. The third terminal 127 is located within the projection of the mutual inductor 131 on the front surface of the circuit board 121 along the length direction of the housing 150, and is spaced from the second terminal 125 along the width direction of the circuit board 121.
[0053] In this embodiment, the third terminal 127 is located within the projection of the mutual inductor 131 along the length direction of the housing 150, and is spaced from the second terminal 125 in the width direction of the circuit board 121. This layout makes full use of the space on the circuit board 121, ensuring that each component can be reasonably arranged within the limited space, and avoiding the complexity of the circuit board 121 design or interference between components caused by overly dense arrangement.
[0054] In an embodiment of the present utility model, please refer to Figure 2 and Figure 4 , the third connector 126 is arranged near one end along the width direction of the first section 1212. The third connector 126 is provided with a third terminal 127. One end of the third terminal 127 penetrates through the third terminal 127 and the circuit board 121 along the length direction of the housing 150, and the other end is bent and passes through the mounting seat 110.
[0055] In this embodiment, the bending design of the third terminal 127 and passing through the mounting seat 110 not only helps to protect the terminal itself, but also can improve the mechanical strength of the overall connection. This setting can reduce the risk of damage to the terminal caused by vibration or external impact during use, thereby extending the service life of the device.
[0056] In one embodiment, the third connector 126 is disposed near one end along the width direction of the first section 1212 and near the mounting base 110. When the present utility model is assembled, the third terminal 127 on the third connector 126 directly passes through the mounting base 110. That is, after the third terminal 127 is aligned with the mounting hole on the mounting base 110, the assembly can be completed, simplifying the installation steps of the third terminal 127 and facilitating automated assembly during mass production.
