Description

Technical Field

[0001] This utility model relates to the field of red and black power supplies, and in particular to a red and black power supply isolation wall socket. Background Technology

[0002] The red and black power isolation wall sockets primarily employ protection technologies against conducted leakage emissions from power lines, including filtering and shielding. High-performance power filters are installed between the two ends connecting the general power supply and the information equipment to minimize conducted leakage emissions entering the general power network. Simultaneously, shielding technology is used on the socket itself to prevent cross-inductive coupling and electromagnetic leakage between power lines, suppressing conducted information leakage from the power lines of connected information equipment, resulting in more stable output.

[0003] However, while red and black power wall sockets have overheat warnings after an overload, rapid overheating can still easily lead to problems such as overheating of the wiring. This is especially true when the device plug is loose, which can not only cause overheating at the socket but also damage the device. Failure to disconnect the power connection in time will also increase the load on the red and black power wall socket. Therefore, to address the above issues, a red and black power wall socket with isolation is provided. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a red and black power isolation wall socket, which mainly solves the technical problem that the power cannot be disconnected in time when the wall socket is overheated, resulting in damage caused by forced insertion.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model relates to a red and black power isolation wall socket, comprising a socket panel, a sealed box installed at the rear of the socket panel, and a retaining box installed at the rear of the sealed box. It also includes: a red marker on one side of the socket panel and a black marker on the other side; a sliding groove installed on both sides of the sealed box for sliding inside the retaining box; limiting blocks installed on both sides of the inner wall of the retaining box to limit the sliding distance of the sliding groove; a wiring port installed at the rear of the retaining box for connecting an external power source; a mounting plate located in the middle of the sealed box, with a filter mounted on its surface and a temperature sensor adjacent to the filter; a shielding plate located in front of the mounting plate; and a fixing plate. The fixed plate is located on the rear side of the mounting plate; the connecting socket is installed inside the upper side of the retention box, and the connecting socket and the wiring port are electrically connected. The connecting socket and the mounting plate are connected by a connecting plug; the control switch is located below the connecting socket, and the control switch and the temperature sensor are connected by a first spring cable; the electric actuator is located below the control switch, facing the mounting plate, and includes a rod that penetrates the fixed plate; the buffer pad is installed at the rear end of the fixed plate, and the buffer pad and the rod are connected; the wire outlet is located below the electric actuator, and the wire outlet is connected to the mounting plate by a second spring cable. The wire outlet is used to connect to the grounding wire.

[0007] Preferably, the surface of the shielding plate is further provided with a socket, which is electrically connected to the mounting plate.

[0008] Preferably, the temperature sensor is located at the center of the mounting plate, and the surface of the mounting plate also includes a voltage regulating module.

[0009] Preferably, the buffer pad and the mounting plate are fixedly connected, the rod and the buffer pad are fixedly connected, the buffer pad is made of plastic material, a rubber layer is provided between the buffer pad and the mounting plate, and the electromagnetic push rod is located at the center of the indwelling box.

Detailed Implementation

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] In the attached diagram, all identical reference numerals refer to the same components.

[0025] Example 1

[0026] like Figures 1-4 As shown, this utility model provides a red and black power isolation wall socket, including a socket panel 1, a sealing box 2 installed at the rear end of the socket panel 1, and a retaining box 3 installed at the rear end of the sealing box 2. It also includes: a red marking 101 on one side of the socket panel 1 and a black marking 102 on the other side of the socket panel 1; a sliding groove 201 installed on both sides of the sealing box 2 for sliding inside the retaining box 3; a limiting block 308 installed on both sides of the inner wall of the retaining box 3, which limits the sliding distance of the sliding groove 201; and a wiring port 301 installed at the rear end of the retaining box 3 for connecting to an external power source. The sealing box 2 can be recessed by elasticity on both sides and inserted into the retaining box 3. After the sealing box 2 is slidably installed into the retaining box 3, the wiring port 301 is connected to the socket panel 1. When the sealing box 2 slides outward, the electrical connection between the sealing box 2 and the retaining box 3 is disconnected, thus avoiding continuous connection.

[0027] To achieve the automatic disconnection function, the sealed box 2 also includes: a mounting plate 4, located in the middle of the sealed box 2, with a filter 401 mounted on its surface and a temperature sensor 402 adjacent to the filter 401; a shielding plate 5, located in front of the mounting plate 4; and a fixing plate 7, located behind the mounting plate 4. The indwelling box 3 also includes: a connecting socket 302, installed on the upper side of the indwelling box 3, electrically connected to a wiring port 301, and connected to the mounting plate 4 by a connecting plug 6; a control switch 303, located below the connecting socket 302, connected to the temperature sensor 402 by a first spring cable 403; and an electric actuator 304, located below the control switch 303. 4. Facing the mounting plate 4, the electric actuator 304 includes a rod 309 that penetrates the fixing plate 7; a buffer pad 305 installed at the rear end of the fixing plate 7 and connected to the rod 309; and a cable outlet 306 located below the electric actuator 304. The cable outlet 306 is connected to the mounting plate 4 by a second spring cable 307 and is used to connect to the grounding wire. Its structure allows the control switch 303 to be activated when the filter 401 or other components rise to a certain threshold due to abnormal temperature. This causes the rod 309 of the electric actuator 304 to be pushed forward, allowing the buffer pad 305 of the mounting plate 4 to move the fixing plate 7 forward until the connector plug 6 and connector socket 302 are separated. At this time, the mounting plate 4 will be in a de-energized state, thereby preventing the components on the surface of the mounting plate 4 from overheating due to overload.

[0028] Furthermore, the surface of the shielding plate 5 is also provided with a socket 501, which is electrically connected to the mounting plate 4; so that the device is mainly connected to the socket 501 after being inserted into the socket panel 1, and the socket 501 is then connected to the mounting plate 4 for filtering.

[0029] Furthermore, the temperature sensor 402 is located at the center of the mounting plate 4, and the surface of the mounting plate 4 also includes a voltage regulating module; this allows the temperature sensor 402 to also sense the heating of the socket 501 or other modules on the mounting plate 4, and when a sense is generated, it will cause the electric push rod 304 to move based on the control switch 303.

[0030] Furthermore, the buffer pad 305 and the mounting plate 4 are fixedly connected, and the rod 309 and the buffer pad 305 are fixedly connected. The buffer pad 305 is made of plastic material, and a rubber layer is provided between the buffer pad 305 and the mounting plate 4. The electromagnetic push rod is located at the center of the indwelling box 3. This reduces the shaking of the sealed box 2 inside the indwelling box 3 when the electric push rod 304 generates a pushing force, and the position pushed by the electromagnetic push rod is the center point of the sealed box 2, which makes it easier for the sealed box 2 to bear the force.

[0031] Furthermore, the limiting block 308 and the slide groove 201 are in a clearance fit, and the socket panel 1 and the sealing box 2 are fixedly connected; this makes it easier for the two sides of the limiting block 308 to be recessed inward when the sealing box 2 is installed in the retention box 3, so that the slide groove 201 can be aligned with the limiting block 308 for installation.

[0032] Furthermore, the surface of the limiting block 308 is provided with a fastening block 8, which is used to fix it to the socket panel 1; the fastening block 8 can be a ball-type snap fastener or a detachable snap fastener connection.

[0033] Specifically, during installation, the placement box 3 is fixedly installed when the wall is grooved, directly placed on the wall surface, and the power cord is installed from the wiring port 301; then the two ends of the first spring cable 403 are connected to the control switch 303 and the upper port at the rear end of the fixing plate 7 respectively, and the second spring cable 307 is also connected to the outlet port and the lower port at the rear end of the fixing plate 7; then the user can press the two sides of the sealing box 2 to form a recess, and install it inside the placement box 3. The slide 201 and the limit block 308 correspond, allowing the sealing box 2 to simply slide back and forth in the slide 201. When inserting, the connecting socket 302 and the connecting plug 6 need to be inserted accordingly. After being inserted to the bottom, the snap-fit ​​block 8 and the socket panel 1 are connected by a snap-fit.

[0034] In use, the user can directly connect the classified equipment to the socket panel 1. The temperature sensor 402 will continuously monitor the internal temperature. When the total power of the connected electrical appliances exceeds the rated power of the socket, the temperature sensor 402 mainly senses the filter 401 and the socket 501 in the circuit, which are prone to temperature rise. When the temperature reaches a certain threshold, the temperature sensor 402 will transmit an electrical signal to the first spring cable 403. After receiving the electrical signal, the control switch 303 will activate the electric push rod 304, which will push the fixing plate 7 to the front end. At this time, the latching block 8 will separate from the socket panel 1. The sealing box 2 will gradually decrease in temperature as the connector plug 6 and connector socket 302 are separated. The current remaining inside will continuously discharge to the ground wire from the second spring cable 307 until the capacitor component inside the sealing box 2 is completely discharged and is in a non-energized state. Then, the user can disassemble the sealing box 2 and take it out for inspection, maintenance or repair. This not only avoids the overall red and black power isolation wall socket from overheating and burning due to overload, but also makes it easy to remove the faulty sealing box 2 in a modular fashion and replace it with a new sealing box 2 for use, without having to disassemble the entire structure.

[0035] Example 2

[0036] The difference from Example 1 is that, as Figure 5 As shown, the connector 6 includes a copper strip 601, which is used to insert into the connector socket 302. High-resistance interfaces 3021 are provided on both sides of the inner wall of the connector socket 302, and a low-resistance interface is provided at the rear end of the inner wall of the connector socket 302.

[0037] The high-resistance interface 3021 and the low-resistance interface are connected in parallel, and both the high-resistance interface 3021 and the low-resistance interface are connected to the wiring port 301.

[0038] Specifically, in Embodiment 1, since the sealed box 2 will be directly de-energized after the connector plug 6 is disconnected from the connector socket 302, the operation items in its classified equipment may be incomplete or unsaved. Therefore, a parallel node of a high-resistance interface 3021 and a low-resistance interface is provided at the connector socket 302. When the copper strip 601 contacts the low-resistance interface, the power is mainly connected from the low-resistance interface, and the high-resistance interface 3021 is idle at this time, and its output current and voltage are both stable values. When the sealed box 2 heats up, the electric push rod 304 will move slowly, at which time the copper strip 601 will separate from the low-resistance interface. At this point, copper strip 601 mainly contacts the high-resistance interface 3021 from the side. Since the input voltage is the same, the current decreases after the resistance increases, so the overheating caused by the current will be alleviated. In this process, the voltage regulation module on the surface of mounting plate 4 stabilizes the voltage, so that the voltage remains stable while the current decreases, so that the output voltage meets the minimum rated current and minimum rated voltage of the classified equipment, and maintains the minimum power output. Before copper strip 601 is disconnected from high-resistance interface 3021, users can save data during the connection of copper strip 601, and can perform subsequent inspection and maintenance after the sealing box 2 is finally disconnected.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
