Description

Technical Field

[0001] This utility model relates to the field of electrical power socket technology, and in particular to a safety-protected electrical power socket with a switch. Background Technology

[0002] In modern electrical appliances, power sockets, as key components connecting power sources and appliances, directly impact the safety and convenience of appliance use. With technological advancements, modular design has gradually become a trend in power socket design. By designing different functional components as detachable modules, the flexibility and maintainability of power sockets are improved. However, existing modular power sockets still present some problems in practical applications.

[0003] For example, utility model patent CN216563869U discloses a power socket with a push-button switch and a fuse. This socket achieves detachable installation of the switch module and fuse module through a modular design. However, this design still requires wire soldering to achieve electrical connections between the modules. This not only increases the complexity of assembly but may also lead to the exposure of wires and solder joints, resulting in safety hazards such as short circuits and open circuits due to desoldering.

[0004] For example, while other existing power socket designs also employ similar modular structures, they similarly fail to effectively address the connection issues between the modules. Typically, electrical connections between functional modules require soldering wires, and the connection between the socket and the internal circuitry of the appliance also necessitates soldering wires and terminals. This traditional connection method is not only inconvenient to assemble, requiring significant time and manpower, but also prone to short circuits, open circuits due to exposed wires and solder joints, thus reducing the safety and reliability of the power socket.

[0005] In summary, while existing power socket technologies have made some progress in modular design, significant shortcomings remain in the electrical connection methods between modules. How to provide a more convenient, safe, and reliable power socket that avoids the various problems associated with traditional soldering connections has become a pressing technical challenge.

[0043] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0044] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0045] In the description of this utility model, it should be noted that the terms "upper," "lower," "front," "rear," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Similarly, "first" and "second" are only for ease of understanding and have no other directional meaning, and cannot be considered as limitations on this utility model.

[0046] like Figure 1 , 4 As shown, a safety-protected electrical power socket 100 with a switch includes a housing 1 and a conductive component 2, a switch module 3 and a fuse module 4 located on the housing 1.

[0047] like Figure 3 , 5 As shown in Figures 6 and 8, the switch module 3 has a first conductive terminal 31 and a live wire terminal 32, as well as a second conductive terminal 33 and a neutral wire terminal 34. The switch module 3 enables the connection and disconnection of the socket circuit, so that when an appliance is connected to AC power, the power supply can be cut off without unplugging the power cord from the wall socket.

[0048] like Figure 6 , 9 As shown in Figure 11, the fuse module 4 is provided with a third conductive terminal 401 and a fourth conductive terminal 402. The fuse module 4 is configured to provide overload protection for the circuit. When the current in the circuit is too high, the fuse 42 will automatically melt and cut off the circuit, thereby protecting the safety of electrical equipment and circuits and avoiding safety accidents such as fires caused by overload.

[0049] like Figure 4 As shown, the conductive component 2 includes a live wire conductor 21, a neutral wire conductor 22, and a ground wire conductor 23. The upper end of the live wire conductor 21 is connected to the third conductive terminal 401, and the lower end has a live wire pin 211. The upper end of the neutral wire conductor 22 is connected to the first conductive terminal 31, and the lower end has a neutral wire pin 221. The upper end of the ground wire conductor 23 has a ground wire terminal 232, and the lower end has a ground wire pin 231. The second conductive terminal 33 and the fourth conductive terminal 402 are electrically connected through a conductive sheet 24 or other means.

[0050] like Figure 1-4As shown, the live wire pin 211, ground wire pin 231, and neutral wire pin 221 extend to the front of the housing 1 to form an external connection S. A window 121 is provided on the rear side of the housing 1, and all conductive parts on the rear side of the housing 1, except for the live wire terminal 32, neutral wire terminal 34, and ground wire terminal 232, are concealed within the housing 1. The live wire terminal 32, neutral wire terminal 34, and ground wire terminal 232 are arranged parallel to each other in the window 121 to form an internal connection P for connection with the quick-connect terminal 200.

[0051] By incorporating conductive component 2, the soldering process between the contacts of the socket itself is eliminated, making installation more convenient. The internal connection part P, adapted to the quick-connect terminal 200, simplifies and extricates wires from electrical appliances, eliminating the need for complex processes like soldering. This quick-connect method not only improves installation and maintenance efficiency but also avoids safety issues caused by exposed wires. Furthermore, all conductive parts on the rear side of the housing 1, except for the live wire 32, neutral wire 34, and ground wire, are concealed within the housing 1. This design effectively prevents conductor exposure, reduces the risk of internal short circuits, improves safety, and extends the equipment's lifespan.

[0052] Furthermore, such as Figure 4 , 7 As shown, the housing 1 includes a housing body 11 and a protective cover 12. The housing body 11, conductive components 2, switching module 3, and fuse module 4 constitute the following... Figure 5 , 6 The assembly shown has a live wire pin 211, a ground wire pin 231, and a neutral wire pin 221 extending to the front of the housing body 11 to form an external connection S. A protective cover 12 has a window 121 and is located on the rear side of the assembly, covering all conductive parts on the rear side of the assembly except for the live wire terminal 32, the neutral wire terminal 34, and the ground wire terminal. The design between the protective cover 12 and the housing body 11 not only makes socket assembly more convenient but also enhances the protection of the internal conductive components 2, preventing foreign objects from entering and causing short circuits or other electrical faults. It also makes the overall appearance of the socket cleaner and reduces potential safety hazards caused by exposed conductive parts.

[0053] like Figure 1-4 As shown, the housing body 11 has a first groove 111, a second groove 112, and a third groove 113 that open to the front and are arranged side by side. The switch module 3 is arranged in the first groove 111 with the push-button switch facing forward. The fuse module 4 is arranged in the second groove 112 with its conductive end facing backward. This side-by-side groove design allows the components to be arranged in an orderly manner within the housing 1, making full use of the internal space of the housing 1, resulting in a compact structure and small size for the entire socket assembly.

[0054] like Figure 4 , 7As shown, the first groove 111 includes a through groove a extending to the rear side of the housing body 11 and a limiting surface b, the limiting surface b being lower than the front surface of the housing body 11. The outer periphery of the insulating shell 35 of the switch module 3 is provided with a limiting protrusion 351 that matches the limiting surface b. The switch module 3 passes through the through groove a, and the limiting protrusion 351 is limited by the limiting surface b.

[0055] like Figure 8 As shown, the insulating shell 35 has elastic latches 352 on both the left and right sides, and the groove wall of the through groove a has a groove with a width adapted to the elastic latches 352. The elastic latches 352 are restricted on both sides by the groove, thereby restricting the vertical displacement of the switch module 3.

[0056] like Figure 8 As shown, the elastic latch 352 has a bent structure, including a vertical segment e connected to the vertical wall of the insulating shell 35, a first bent segment f extending obliquely outward from the vertical segment e, and a second bent segment g extending obliquely inward from the first bent segment f. The outer surface of the second bent segment g has a serrated surface structure h composed of multiple parallel protruding ridges. The second bent segment g engages with the groove wall of the latching slot, and the serrated surface structure h increases the friction, thereby making the connection more secure. This fixing method not only makes the installation of the switch module 3 in the shell 1 more stable, but also facilitates the disassembly and replacement of the switch module 3, improving the reliability and maintainability of the product.

[0057] like Figure 3 , 8 As shown, the first conductive terminal 31 and the live wire terminal 32, as well as the second conductive terminal 33 and the neutral wire terminal 34, are all convex structures. The first conductive terminal 31 and the live wire terminal 32 are parallel to each other in the width direction, the second conductive terminal 33 and the neutral wire terminal 34 are parallel to each other in the width direction, the first conductive terminal 31 and the second conductive terminal 33 are parallel to each other vertically, and the live wire terminal 32 and the neutral wire terminal 34 are parallel to each other vertically and separated by a first isolation wall 353. At the same time, the window 121 is also provided with a second isolation wall N that separates the live wire terminal 32 and the ground wire terminal 232, thereby forming a three-interface structure in the window 121.

[0058] The live wire 32, neutral wire 34, and ground wire are arranged in parallel within the window 121 to form an inner connection portion P for connection with the quick-connect terminal 200. The window 121 also includes a second isolation wall separating the live wire 32 and the ground wire, thus creating a three-interface structure. This structure not only makes the layout of the conductive terminals more rational and facilitates the connection of the quick-connect terminal 200, but also improves the accuracy and reliability of the connection, reducing connection errors caused by misoperation.

[0059] The live wire terminal 32, neutral wire terminal 34, and ground wire terminal are all convex structures perpendicular to the plane of window 121. The live wire terminal 32, neutral wire terminal 34, and ground wire terminal are arranged in window 121 with their width sides aligned.

[0060] like Figure 4 , 9 As shown in Figure 11, the fuse module 4 includes a fuse box 41, a fuse 42, a first conductor 43, and a second conductor 44. The fuse box 41 includes a box body 421 that is adapted to the shape of the second groove 112. A clamping piece 422 is provided on the rear side of the box body 421. One end of the clamping piece 422 is connected to the box body 421, and the other end forms a clamping opening j. The fuse 42 enters the clamping portion between the clamping piece 422 and the box body 421 through the clamping opening j. The fuse 42 extends in the same direction as the box body 421, and its two ends extend beyond the two ends of the clamping piece 422.

[0061] The first conductor 43 includes an integrally formed first clamping body 431 and a first conductive insert 432, the end of which is a third conductive end 401. The second conductor 44 includes an integrally formed second clamping body 441 and a second conductive insert 442, the end of which is a fourth conductive end 402.

[0062] The first clamping body 431 and the second clamping body 441 both include two jaws v that have clamped the fuse 42 and made it conductive, and the first conductive insert 432 and the second conductive insert 442 protrude to the rear side.

[0063] like Figure 9-11 As shown, the lower end of the conductive piece 24 is provided with a first socket 242, and the upper end of the live wire conductor 21 is provided with a second socket 212. The first conductive piece 432 is inserted into the first socket 242 and the second conductive piece 442 is inserted into the second socket 212 to achieve electrical connection.

[0064] like Figure 4 , 9 As shown, the side of the box body 421 away from the clamping opening j is provided with a positioning protrusion q, and the partition wall of the second groove 112 and the third groove 113 is provided with a strip-shaped notch w. The positioning protrusion q extends into the strip-shaped notch w to realize the positioning of the fuse module 4 on the shell body 11.

[0065] like Figure 5-7 As shown in Figures 9 and 11, the bottom wall of the second groove 112 is provided with through holes that correspond to the first conductive insert 432 and the second conductive insert 442. The ends of the first conductive insert 432 and the second conductive insert 442 pass through these through holes to the outside of the rear wall of the housing body 11. The positioning protrusion and the strip-shaped notch enable accurate positioning of the fuse module 4. The clamping bodies of the first conductor 43 and the second conductor 44 firmly clamp the fuse 42, ensuring reliable connection of the fuse module 4 in the circuit.

[0066] like Figure 4-7As shown, the rear wall of the shell body 11 corresponding to the second groove 112 and the third groove 113 is provided with a receiving groove group 114 that matches the conductive component 2, and the conductive component 2 is disposed in the receiving groove group 114. The receiving groove group 114 is divided by multiple bent protruding ridges n to form multiple receiving grooves m that are respectively adapted to the shapes of the live wire conductor 21, neutral wire conductor 22, ground wire conductor 23 and conductive sheet 24. The live wire conductor 21, neutral wire conductor 22, ground wire conductor 23 and conductive sheet 24 are placed in the corresponding receiving grooves m. This separation design of the receiving groove group 114 not only allows each conductive component to have an independent placement space in the shell 1, avoiding mutual interference, but also facilitates positioning and fixing during production and assembly, improving production efficiency.

[0067] like Figure 4-6 As shown in Figures 10-13, the live wire conductor 21 includes a first strip plate portion 213. The neutral wire conductor 22 includes a second strip plate portion 223. The ground wire conductor 23 includes a third strip plate portion 233. The first strip plate portion 213, the second strip plate portion 223, and the third strip plate portion 233 are parallel to each other. One side of the first strip plate portion 213, the second strip plate portion 223, and the third strip plate portion 233 in the thickness direction is attached to the bottom wall of the corresponding receiving groove.

[0068] like Figure 5-7 As shown in Figure 10, the bottom wall of the ground wire receiving groove for placing the ground wire conductor 23 is provided with a protrusion y, and the ground wire conductor 23 is provided with a positioning hole u. The protrusion y extends into the positioning hole to realize the positioning of the ground wire conductor 23.

[0069] like Figure 10 As shown, the first conductive end 31 and the third conductive end 401 are parallel, convex structures. The upper ends of the live wire conductor 21 and the neutral wire conductor 22 are both semi-frame socket structures. The semi-frame socket structure includes opposing clamping walls T and a bottom wall connecting the two clamping walls T. The clamping walls T can elastically deform to change the diameter of the socket. The two clamping walls T clamp the width sides of the corresponding conductive ends, and the side of the conductive end located on the thickness side is close to and in contact with the bottom wall, thereby achieving electrical conduction.

[0070] like Figure 3 , 7 As shown, the rear wall of the shell body 11 corresponding to the second groove 112 and the third groove 113 is provided with a protruding buckle L. The free end of the protruding buckle L is provided with a bent latch s. The protective cover 12 is provided with a latching hole 124. The protruding buckle L passes through the latching hole 124, and the latching tongue locks into the rear wall of the protective cover 12, thereby connecting the protective cover 12 and the shell body 11. A closed space is formed between the protective cover 12 and the shell body 11, with only the window 121 open.

[0071] like Figure 7As shown, the protective cover 12 includes an annular protrusion 122 surrounding the window 121 and an abutment surface 123 located around the window 121 and below the annular protrusion 122.

[0072] like Figure 2-3 As shown in Figure 14, the quick-connect terminal 200 includes three independent wire snap-fit ​​channels D. Each wire snap-fit ​​channel corresponds to a plug part 201, and each plug part 201 corresponds to a conductive element 202. A plug part 201 connects with one of the live wire terminal 32, neutral wire terminal 34, and ground wire terminal to achieve physical connection and electrical conduction at the same time.

[0073] The quick-connect terminal 200 includes a housing 205 and three insertion portions 201 forming a mating protrusion whose contour conforms to the window 121. The mating protrusion of the quick-connect terminal 200 conforms to the window 121, and the contour of the housing conforms to the annular protrusion 122, partially enclosing it. This design provides clear guidance to the user both visually and tactilely, further reducing installation difficulty. The end face of the housing contacts the abutment surface 123, increasing connection stability.

[0074] In this embodiment, the insertion part 201 and the conductive element 202 are integrated. This design ensures that during the insertion process, the conductive element 202 can accurately align with the corresponding conductive end, achieving a reliable electrical connection. Simultaneously, the conductive element 202 extends inward into the housing to cooperate with the conductive spring 204 controlled by the operating handle 203 to form a wire engaging channel, further simplifying the connection steps and improving connection stability.

[0075] The outer surface of the plug-in part 201 is coated with an insulating coating. Through the structural design of the plug-in part 201 and the isolation wall, the installation fault tolerance is improved, and fast and accurate docking can be achieved even in dim environments.

[0076] Preferably, the end structure formed by the integral construction of the plug portion 201 and the conductive element 202 is consistent with the semi-frame socket structure of the live wire conductor 21 and the neutral wire conductor 22. The clamping wall T of the semi-frame socket structure is bent inward to form an arc-shaped clamping surface F. This arc-shaped design can better adapt to the shape of the protruding structure inserted therein, and form surface contact with both sides of the width of the protruding structure during clamping, providing a more uniform clamping force, avoiding loosening due to vibration, and ensuring a stable electrical connection.

[0077] This invention introduces a power socket structure with integrated safety protection and convenient installation, incorporating a switch. Specific examples are used to illustrate the principles and implementation methods of this invention. The descriptions of these embodiments are merely for the purpose of aiding understanding of this invention and its core concepts. It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of this invention.
