Description

Technical Field

[0001] This utility model relates to the field of AC electronic switch technology, and in particular to an AC electronic switch with remote control. Background Technology

[0002] Most existing AC electronic switches adopt an integrated housing structure. This structure is extremely inconvenient when installing and repairing the circuit board, requiring the entire housing to be disassembled, which increases the difficulty of operation and time cost. At the same time, since the circuit board generates a lot of heat during the operation of the electronic switch, if it cannot be dissipated in a timely and effective manner, it will affect the performance and life of the circuit board, and may even cause the electronic switch to be damaged.

[0003] To address these issues, an AC electronic switch with remote control is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology and solve the problems of inconvenient installation and maintenance and poor heat dissipation, this utility model provides an AC electronic switch with remote control.

[0005] This utility model is achieved using the following technical solution:

[0006] An AC electronic switch with remote control includes a housing, a circuit board, and a connector. The circuit board is installed inside the housing, and the connector is located at the bottom of the housing and connected to the internal circuit board. The connector is threaded and used to connect to an external signal line. The housing has a split structure, including an upper housing and a lower housing. The lower housing has four connecting posts inside, which are fixed around the perimeter of the lower housing. The circuit board is fixed to the connecting posts by bolts.

[0007] The housing is also equipped with a heat dissipation device, which is used to dissipate heat from the internal circuit board.

[0008] The heat dissipation device includes a fan, which is fixed inside the upper housing. The surface of the upper housing is provided with an exhaust hole. The two side walls of the lower housing are symmetrically provided with air intake grilles, which are located on the side walls of the lower part of the lower housing. The inner walls of the air intake grilles and the inner walls of the exhaust holes are respectively provided with filters.

[0009] The upper housing has symmetrical fixing blocks on its side wall, and each fixing block has a snap-fit ​​post. The lower housing has a matching buckle on its side wall. When the upper housing and the lower housing are fixedly installed, the snap-fit ​​post is engaged in the buckle.

[0010] The bottom of the housing is also provided with a fastening plate, which is fixed to the bottom of the housing by bolts. The connector is fixed to the lower surface of the fastening plate, and the fastening plate is provided with through holes for the lines connecting the connector to the internal circuit board to pass through.

[0011] The lower housing has internal reinforcing ribs in the shape of a cross, and the upper housing has a nameplate on its front side, which is attached to the surface of the upper housing.

[0012] The lower housing is provided with two lifting lugs, which are symmetrically fixed to the top of the lower housing.

[0013] The present invention has the following advantages over the prior art:

[0014] 1. By installing a heat dissipation device inside the switch, the air convection formed by the fan, air intake grille and exhaust vent can effectively dissipate the heat generated by the circuit board to the outside of the housing, ensuring the temperature stability of the electronic switch during operation and extending the service life of the electronic switch.

[0015] 2. By designing the housing as a split structure, the split housing structure allows for the installation and maintenance of circuit boards without disassembling the entire housing. Only the upper or lower housing needs to be opened, which greatly improves operational efficiency and reduces maintenance costs. Furthermore, the threaded connector design and the fastening plate ensure the stability of the connection between the connector and the external signal lines and the internal circuit board, reducing the possibility of signal interruption and poor contact.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figures 1 to 7 As shown, an AC electronic switch with remote control includes a housing, a circuit board 5, and a connector 7. The circuit board 5 is installed inside the housing, and the connector 7 is located at the bottom of the housing and connected to the internal circuit board 5. The connector 7 is threaded and used to connect to external signal lines. This threaded connection method ensures the stability of the connection and effectively prevents signal interruption or poor contact. The housing has a split structure, including an upper housing 1 and a lower housing 2. This split design allows for easy installation and maintenance of the circuit board 5 by simply opening either the upper housing 1 or the lower housing 2, without disassembling the entire housing, greatly improving operational convenience. The lower housing 2 has four connecting posts 23 inside, which are fixed around the perimeter of the lower housing 2. The circuit board 5 is fixed to the connecting posts 23 by bolts. The connecting posts 23 securely mount the circuit board 5 onto the lower housing 2, ensuring the stability of the circuit board 5 during operation and reducing circuit failures caused by vibration or other reasons.

[0027] The housing is also equipped with a heat dissipation device, which is used to dissipate heat from the internal circuit board 5. The heat dissipation device can effectively reduce the heat generated by the circuit board 5 during operation, ensuring the performance and lifespan of the electronic switch.

[0028] The heat dissipation device includes a fan 4, which is fixed inside the upper housing 1. The surface of the upper housing 1 is provided with an exhaust hole 11, and the two side walls of the lower housing 2 are symmetrically provided with air intake grilles 21. The air intake grilles 21 are located on the lower side walls of the lower housing 2. In order to prevent dust and other impurities from entering the housing and affecting the performance of the electronic switch, filters are provided on the inner walls of the air intake grilles 21 and the inner walls of the exhaust holes 11, respectively. The filters can effectively filter dust and impurities in the air and ensure the cleanliness of the housing. When working, the fan 4 rotates, and the outside air enters the housing through the air intake grilles 21 on both sides of the lower housing 2. After absorbing the heat generated by the circuit board 5, it is discharged from the exhaust holes 11 on the surface of the upper housing 1, forming air convection, thereby achieving the purpose of heat dissipation.

[0029] The upper housing 1 has symmetrically arranged fixing blocks 13 on its side wall, and the fixing blocks 13 have snap-fit ​​posts 14. The lower housing 2 has matching buckles 25 on its side wall. When the upper housing 1 and the lower housing 2 are fixedly installed, the snap-fit ​​posts 14 are engaged in the buckles 25. This snap-fit ​​structure makes the installation and disassembly of the upper housing 1 and the lower housing 2 more convenient and quick, while also ensuring the stability of the connection between the two.

[0030] The bottom of the housing is also provided with a fastening plate 6, which is fixed to the bottom of the housing by bolts. The connector 7 is fixed to the lower surface of the fastening plate 6. The fastening plate 6 is provided with through holes for the wiring connecting the connector 7 to the internal circuit board 5. The fastening plate 6 not only further stabilizes the connector 7, but also protects and organizes the connecting wiring, making the internal structure of the electronic switch more neat and orderly.

[0031] The lower housing 2 has a reinforcing rib 22 inside, which is cross-shaped. The upper housing 1 has a nameplate 12 on its front side, which is attached to the upper housing 1. The reinforcing rib 22 can enhance the structural strength of the lower housing 2 and improve its resistance to deformation, ensuring that the housing will not deform when the electronic switch is subjected to external force, thereby protecting the internal circuit board 5 and other components. The nameplate 12 can mark the model, parameters, manufacturer and other information of the electronic switch, which is convenient for users to identify and use.

[0032] The lower housing 2 is provided with two lifting lugs 24 on the top, which are symmetrically fixed on the top of the lower housing 2. The lifting lugs 24 allow the electronic switch to be installed by slinging, increasing the flexibility and convenience of installation.

[0033] The working principle of this utility model is as follows: When in use, four connecting posts 23 are fixed around the lower housing 2 to ensure that the position of the connecting posts 23 is accurate and stable. Then, the circuit board 5 is fixed to the connecting posts 23 with bolts. Note that the tightening force of the bolts should be moderate to avoid damaging the circuit board 5 or the connecting posts 23. Next, the fan 4 is fixed inside the upper housing 1 to ensure that the installation position of the fan 4 is correct and that it can work normally. Finally, the lower housing 2 is placed in a suitable position, the upper housing 1 is aligned with the lower housing 2, and the snap-fit ​​post 14 is engaged in the snap-fit ​​25 on the side wall of the lower housing 2 to complete the initial assembly of the upper housing 1 and the lower housing 2.

[0034] Secure the fastening plate 6 to the bottom of the housing with bolts to ensure that the fastening plate 6 is installed firmly. Fix the connector 7 to the lower surface of the fastening plate 6. Note that the thread direction of the connector 7 should be correct to facilitate connection with external signal lines. Connect the lines that connect the connector 7 to the internal circuit board 5 through the through holes on the fastening plate 6 to ensure that the lines are connected correctly and firmly to avoid short circuits or open circuits.

[0035] When the device is working, the heat dissipation device is activated, and the fan 4 is driven by the motor to rotate the blades. When the fan 4 rotates, it generates airflow. External air enters the housing through the air intake grille 21 of the lower housing 2, absorbs the heat generated by the circuit board 5, and is blown by the fan 4 to the exhaust port 11 of the upper housing 1 to form an air circulation, thereby effectively reducing the temperature inside the housing.

[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
