Abstract
Description
Technical Field
[0001] This utility model relates to the field of power socket technology, and in particular to a power socket with a protective device. Background Technology
[0002] In our daily lives, we frequently use sockets. A socket is a receptacle with one or more electrical wires that can be inserted. Various wires can be inserted through it, making it easy to connect to other circuits. The connection and disconnection of the circuit is achieved by connecting and disconnecting the wires and copper parts. Sockets can also prevent leakage. There are multiple connection terminals installed inside the socket for connecting the power supply. The socket shell surface has holes corresponding to the internal connection terminals, usually in groups of two or three holes. With the development of the times, connection holes that fit the connection of mobile phone data cables have appeared.
[0003] However, currently, most socket openings are located at the top of the socket casing, which are exposed. Over time, dust accumulates inside the socket, and the pressure of dust increases the resistance at the connection points between the internal terminals and electrical equipment, leading to more severe overheating. In humid environments (such as bathrooms or kitchens), moisture and oil vapor can enter the socket and corrode the internal terminals. Prolonged corrosion can easily cause leakage and damage at the socket connection points.
[0004] Therefore, it is necessary to provide a new type of power socket with a protective device to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a power socket with a protective device.
[0006] The present invention provides a power socket with a protective device, including a socket body, a plurality of connecting terminals installed inside the socket body, a socket hole that matches the upper end of the socket body corresponding to the internal connecting terminals, and a protective mechanism installed on the upper end of the socket body.
[0007] The protective mechanism includes two protective shells. The upper ends of the socket body are rotatably connected to the protective shells via a pivot. Two limiting grooves are opened on both sides of the upper end face of the socket body. Limiting springs are fixedly connected to the bottom surface of the two limiting grooves. The upper ends of the multiple limiting springs are fixedly connected to the outer wall of the corresponding protective shell. When the two protective shells are closed, multiple through wiring holes are opened on the opposite side. Sealing gaskets are embedded inside the multiple wiring holes.
[0008] Preferably, the longitudinal section of both protective shells is a quarter circle, and when the two protective shells are closed, they together form a downward-facing semicircle.
[0009] Preferably, the length of the plurality of limiting springs is less than the depth of the limiting groove when they are not stretched, and the plurality of limiting springs are still stretched when the corresponding protective shells are completely closed.
[0010] Preferably, the longer side of the plurality of limiting grooves is larger than the diameter of the limiting spring.
[0011] Preferably, each of the two protective shells has a plurality of positioning magnets embedded on the side that is in contact with each other when closed, and the magnetic poles of the plurality of positioning magnets located on different protective shell surfaces are opposite.
[0012] Preferably, a connecting wire for connecting to an external power source is fixedly connected to one side of the socket body, and mounting plates are fixedly connected to the lower edges of both sides of the socket body, with through threaded holes at the upper ends of multiple mounting plates.
[0013] Compared with related technologies, the power socket with a protective device provided by this utility model has the following beneficial effects:
[0014] This utility model provides a power socket with a protective device. In specific implementation:
[0015] When in use, the protective shell is rotated around the pivot to open it. At this time, the protective shell drives the corresponding limit spring to rotate outward and increases the tensile deformation of the limit spring. The plug of the appliance is inserted into the socket. Then the protective shell is released, and the limit spring provides a reaction force to reset the two protective shells, thereby protecting the socket and preventing oil or water droplets from entering the socket and corroding the internal connection terminals. At the same time, after the protective shell is closed, the wire connected to the plug extends out from the wiring hole. At this time, the sealing gasket and the wire are pressed against each other to form a relatively sealed state, which to a certain extent prevents water vapor or oil vapor from entering the socket body and corroding the connection terminals. This, to a certain extent, prevents the device from leakage due to water or oil corrosion and extends the service life of the device.
[0016] After the protective shell is closed, the limiting spring is still in a stretched state, which allows the limiting spring to still provide a certain reaction force, causing the two protective shells to squeeze against each other, thereby increasing the squeezing force between the corresponding sealing gasket and the wire, further enhancing the sealing performance and improving the protection effect.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please refer to the following: Figure 1 - Figure 4 ,in, Figure 1 A front axonometric view of a power socket with a protective device provided by this utility model; Figure 2 An overall isometric view of a power socket with a protective device provided by this utility model; Figure 3 Axonometric view of the socket body of a power socket with a protective device provided by this utility model; Figure 4 for Figure 2 Enlarged view of point A in the middle.
[0024] In the specific implementation process, such as Figure 1 - Figure 4 As shown, a power socket with a protective device includes a socket body 1. Several connection terminals are installed inside the socket body 1. The upper end of the socket body 1 has a socket hole that matches the internal connection terminals. A protective mechanism is installed on the upper end of the socket body 1. The protective mechanism includes two protective shells 3. The protective shells 3 are rotatably connected to the upper ends of the socket body 1 via a pivot 2. Two limiting grooves 4 are opened on both sides of the upper end of the socket body 1. Limiting springs 5 are fixedly connected to the bottom surface of the two limiting grooves 4. The upper ends of the multiple limiting springs 5 are fixedly connected to the outer wall of the corresponding protective shell 3. When the two protective shells 3 are closed, multiple through wiring holes 6 are opened on the opposite side. Sealing gaskets 7 are embedded inside the multiple wiring holes 6.
[0025] Both protective shells 3 have a quarter-circle longitudinal section, and when the two protective shells 3 are closed, they together form a downward-facing semicircle.
[0026] It should be noted that the above solution ensures that the protective shell 3 does not have sharp surfaces or corners when closed, thereby improving the safety of the modified device.
[0027] When not stretched, the length of the multiple limiting springs 5 is less than the depth of the limiting groove 4, and the multiple limiting springs 5 are still stretched when the corresponding protective shell 3 is completely closed.
[0028] It should be noted that, through the above scheme, since the limiting spring 5 is still in a stretched state, the limiting spring 5 still provides a certain reaction force, which causes the two protective shells 3 to squeeze each other, thereby increasing the squeezing force between the corresponding sealing gasket 7 and the wire, further enhancing the sealing performance and improving the protection effect.
[0029] The longer side of the multiple limiting grooves 4 is larger than the diameter of the limiting spring 5;
[0030] It should be noted that, through the above scheme, the limiting spring 5 can rotate within a certain range along with the protective shell 3, thereby preventing the limiting spring 5 from bending laterally at the part parallel to the upper surface of the heating body 1, and thus extending its service life.
[0031] When the two protective shells 3 are closed, multiple positioning magnets 8 are embedded on the side that is in contact with each other. The magnetic poles of the multiple positioning magnets 8 located on different surfaces of the protective shells 3 are opposite.
[0032] It should be noted that, through the above scheme, after the two protective shells 3 are closed, the mutual attraction between the positioning magnets 8 can further enhance the squeezing force between the two protective shells 3, thereby further improving the sealing effect and making the protection effect better.
[0033] A connecting wire 9 for connecting to an external power source is fixedly connected to one side of the socket body 1. Mounting plates 10 are fixedly connected to the lower edges of both sides of the socket body 1. Multiple mounting plates 10 have through threaded holes at their upper ends.
[0034] The working principle of this utility model is as follows: When in use, the protective shell 3 is rotated to both sides around the rotating shaft 2 to open it. At this time, the protective shell 3 drives the corresponding limiting spring 5 to rotate outward and increases the tensile deformation of the limiting spring 5. The plug of the electrical appliance is inserted into the socket. Then, the protective shell 3 is released, and the limiting spring 5 provides a reaction force to reset it, causing the two protective shells 3 to close, thereby protecting the internal socket and preventing oil or water droplets from entering the socket and corroding the internal connecting terminals. At the same time, after the protective shell 3 is closed, the wire connected to the plug extends out from the wiring hole 6. At this time, the sealing gasket 7 and the wire are pressed against each other to form a relatively sealed state, thereby preventing corrosion to a certain extent. To prevent water vapor or oil vapor from entering the socket body 1 and corroding the connection terminals, the device is protected from leakage due to water or oil corrosion, thus extending its service life. After the protective shell 3 is closed, the limit spring 5 is still stretched, which provides a certain reaction force, causing the two protective shells 3 to press against each other. This increases the pressure between the corresponding sealing gasket 7 and the wire, further enhancing the seal and improving the protection effect. After the two protective shells 3 are closed, the positioning magnets 8 attract each other, which further enhances the pressure between the two protective shells 3, thereby further improving the sealing effect and making the protection effect even better.
[0035] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
