Description

[Technical field]

[0001] The present invention relates to an expansion socket tap, and more particularly to a movable connection conversion socket tap with automatic earth leakage breaker function and automatic overload breaker function. [Background technology]

[0002] An overload protector is installed in an environmental power supply control box for a home, office, outdoor stage, etc., so that when too many electrical appliances are plugged into the associated power outlet tap, or when the entire outlet tap requires an excessive amount of current, the overload protector immediately cuts off the electrical circuit path of each wall outlet, preventing the occurrence of dangers such as excessive or inappropriate use of electricity. Summary of the Invention [Problem to be solved by the invention]

[0003] However, this type of technical means of cutting the electrical circuit of the outlet tap in response to an overload cannot provide additional protection against abnormalities in the amount of current, and when the electrical circuit of the power supply control box is cut off, the power supply to all wall sockets on the circuit is stopped, and the problematic outlet tap alone is not cut off. As a result, a momentary power outage is often caused in large-scale equipment, causing inconvenience to users.

[0004] In addition, when a leakage current problem occurs in an electrical appliance, the current amount is detected for each wall outlet and the power supply path of the outlet tap is cut off, thereby improving the shortcomings of the prior art mentioned above. It also solves the problem of wall outlets being already fixed and difficult to change when carrying out interior renovation work on a residence during building interior renovation work. The present invention is currently researching how to further perfect the electrical safety of the environment and the comfort of using electricity in daily life through the flexible installation and removal functions provided by the movable connection conversion outlet tap.

[0005] The present invention has been made in consideration of the above problems, and its objective is to provide a movable connection conversion outlet tap that provides functions such as automatic leakage current interruption and automatic overload interruption to improve the electrical safety of commercial power sources, thereby ensuring the stability and safety of power supply from environmental power sources. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention discloses a movable connection conversion outlet tap having an automatic leakage current interruption function and an automatic overload interruption function, the movable connection conversion outlet tap comprising a housing, a power supply module, and a leakage current monitoring and control module, the housing is installed to present a hollow case body, and a connection plug is provided on the rear side thereof for connecting to an external wall outlet by inserting it into the wall outlet, the power supply module is provided to be enclosed within the housing, and is provided with at least one AC power socket, the power supply module is electrically connected to the connection plug to receive power from a commercial power source via the wall outlet and transfer and output power from the commercial power source via the AC power socket, and the leakage current monitoring and control module is provided within the housing, The leakage current monitoring and control module is provided so as to be enclosed within the body and is electrically connected to the power supply module. The leakage current monitoring and control module is provided with a power supply status indicator lamp and a manual power restoration switch. When the leakage current monitoring and control module learns through monitoring and control the power of the commercial power supply supplied from the AC power plug hole, it drives the power supply status indicator lamp to emit an indication light, and at the same time detects the current usage state of the AC power plug hole, and when the state is abnormal, it closes the operation of the power supply module to stop the transfer of power from the commercial power supply to the AC power plug hole and drives the power supply status indicator lamp to emit a warning light. The manual power restoration switch is provided for restoring the transfer of power from the commercial power supply to the AC power plug hole by manually pressing it. Effect of the Invention

[0007] In addition, by installing the connection cord, the movable connection conversion outlet tap can be made more flexible, thereby extending the installation distance and position of the outlet tap, and providing high flexibility and freedom in electricity usage.

[0009] <First Example> Please refer to Fig. 1. Fig. 1 is a configuration diagram of a first preferred embodiment of the present invention. As shown in the figure, a movable connection conversion outlet tap 1 with automatic leakage current interruption function and automatic overload interruption function includes a housing 10, a power supply module 11, and a leakage current monitoring and control module 12, the housing 10 encloses the power supply module 11 and the leakage current monitoring and control module 12, and the leakage current monitoring and control module 12 is electrically connected to the power supply module 11. The housing 10 is installed to present a hollow case body, and a connection plug 100 is provided on the rear side, the power supply module 11 is provided with at least one AC power plug hole 110, and the power supply module 11 is electrically connected to the connection plug 100, and the leakage current monitoring and control module 12 is provided with a power supply state indicator lamp 120 and a manual power return energization switch 121.

[0010] The connection plug 100 is provided for plugging into an external wall outlet (not shown) for connection, and the power supply module 11 receives commercial power from the wall outlet via the connection plug 100, and transfers and outputs the commercial power via the AC power socket 110. Furthermore, when the leakage current monitoring and control module 12 detects the commercial power supplied from the AC power socket 110 through monitoring and control, it drives the power supply status indicator lamp 120 to emit an indication light. At this time, the leakage current monitoring and control module 12 detects the current usage state of the AC power outlet 110, and when the state is abnormal, closes the operation of the power supply module 11 to stop the power transfer from the commercial power source to the AC power outlet 110, and drives the power supply state indicator lamp 120 to emit a warning light to notify that the outlet tap has already entered an automatic cut-off state, thereby ensuring electrical safety by automatically cutting off the power when a leakage current occurs, and at the same time, notifying the user of the leakage current situation so that he or she can more actively check the equipment status, thereby achieving the benefit of effectively ensuring the safety of the user's life and property. Furthermore, after the user eliminates the leakage problem of the equipment, the operating ability of the commercial power source power transfer to the AC power outlet 110 can be restored by manually pressing the manual power restoration energization switch 121.

[0011] <Second Example> Please refer to Figures 2 and 3. Figures 2 and 3 are schematic diagrams of a second preferred embodiment of the present invention. As shown in the figures, a movable connection conversion outlet tap 1 with automatic earth leakage breaker function and automatic overload breaker function includes a housing 10, a power supply module 11, an earth leakage monitoring and control module 12, and an overload monitoring and control module 13. The housing 10 encloses the power supply module 11, the earth leakage monitoring and control module 12, and the overload monitoring and control module 13. The housing 10 is installed to present a hollow case body and is joined to a cover housing and a bottom housing. A connection plug 100 is provided on the rear side of the housing 10. The power supply module 11 is electrically connected to the connection plug 100, the earth leakage monitoring and control module 12 is electrically connected to the power supply module 11, and the overload monitoring and control module 13 is electrically connected to the power supply module 11. The power supply module 11 is provided with at least one AC power socket 110, and may be provided in a number of installation configurations, for example with three or more AC power sockets 110; the earth leakage monitoring and control module 12 is provided with a power supply status indicator lamp 120, a manual power restoration switch 121, and a manual earth leakage breaker switch 122; and the overload monitoring and control module 13 is provided with an overload protection switch 130.

[0012] The connection plug 100 is provided for plugging into an external wall outlet (not shown) for connection, and the power supply module 11 receives commercial power from the wall outlet via the connection plug 100, and transfers and outputs the commercial power via the AC power socket 110. When the leakage current monitoring and control module 12 learns the commercial power supplied from the AC power socket 110 through monitoring and control, it drives the power supply status indicator lamp 120 to emit an indicator light, for example, with a green light color. At this time, the leakage current monitoring and control module 12 detects the current usage state of the AC power outlet 110, and when the state is abnormal, closes the operation of the power supply module 11 to stop the power transfer from the commercial power source to the AC power outlet 110, and drives the power supply state indicator lamp 120 to emit a warning light, for example, a red light, to notify that the outlet tap has already automatically entered a cut-off state, so that the power is automatically cut off when a leakage current occurs to ensure electrical safety, and at the same time, the user is informed of the leakage current situation and is provided to more actively inspect the equipment state, thereby achieving the benefit of effectively ensuring the safety of the user's life and property. Furthermore, after the user eliminates the leakage current problem of the equipment, the operating ability of the commercial power source power transfer to the AC power outlet 110 can be restored by manually pressing the manual power return switch 121, for example, an electromagnetic relay.

[0013] In order to check that the earth leakage monitoring and control module 12 is working properly, first, all the electrical wiring plugs on the adjustable connection conversion outlet tap 1 are made removable, and the outlet tap is returned to a no-load, no-power state (at this time, the power supply status indicator lamp 120 lights up green). Then, by manually pressing the manual earth leakage breaker switch 122, such as an electromagnetic relay, the adjustable connection conversion outlet tap 1 changes from a power supplying state to a cut-off state, i.e., the outlet tap is preset to a ground leakage state and is made to indicate a cut-off state. At this time, the power supply status indicator lamp 120 should change its color from green to red to indicate this. Furthermore, if it is observed and detected that the power supply status indicator lamp 120 has not changed from the green indication light to the red warning light, it indicates that the earth leakage monitoring and control module 12 has failed and is unable to detect the presence or absence of ground leakage in the electronic equipment having the plugs, and therefore that the adjustable connection conversion outlet tap 1 needs to be replaced or maintained. Furthermore, after the light color of the power supply status indicator lamp 120 changes from green to red to indicate the cut-off state, when the manual power restoration switch 121 is pressed to switch it into the power supply state, the light color of the power supply status indicator lamp 120 must change from red to green. At this time, if the light color of the power supply status indicator lamp 120 does not change from red to green, that is, the leakage current monitoring and control module 12 has broken down and is no longer able to detect the presence or absence of leakage in the electrically connected home appliances, indicating that the movable connection conversion outlet tap 1 needs to be replaced or maintained.

[0014] At the same time, the overload monitoring and control module 13 also synchronously detects the current usage status of the multiple AC power sockets 110, and when the current usage exceeds the rated value, closes the overload protection switch 130 to stop the power transfer to the AC power socket 110, thereby preventing damage and danger to the electrical appliances. It is worth noting that the arrangement direction of the components in the AC power socket 110 is not limited, and they may be arranged in the forward direction, or in the left direction, right direction, or reverse direction according to the general usage pattern.

[0015] <Third and Sixth Examples> Please refer to Figures 4, 5 and 9. Figures 4 and 5 are schematic diagrams of the third preferred embodiment of the present invention, and Figure 9 is a perspective schematic diagram of the sixth preferred embodiment of the present invention. The power supply module 11 is further provided with at least one DC power plug 111. When the power supply module 11 receives commercial power from a wall outlet through the connection plug 100, the power supply module 11 uses the commercial power to rectify and form DC power, and outputs it through the DC power plug 111. The multiple DC power plugs 111 may be USB ports with multiple usage modes, such as USB Type-A and USB Type-C, and provide DC currents of 1 to 3.1 amperes (A) and 2 to 3.1 amperes. At the same time, the overload monitoring and control module 13 synchronously detects the current usage status of the AC power plug port 110 and the DC power plug port 111, and when the current usage exceeds the rated value, closes the overload protection switch 130 to stop the transfer of power to the AC power plug port 110 and the DC power plug port 111, thereby preventing damage to electrical appliances and the occurrence of danger.

[0016] In this embodiment, the leakage current monitoring and control module 12 can also detect and record the current usage status of each of the AC power outlets 110, and when the current usage status of the AC power outlets 110 is abnormal, it will cut off the electric circuit of the corresponding AC power outlet 110 to stop the transfer of commercial power, and based on this, a plurality of power supply status indicator lamps 120 may be provided corresponding to the number of AC power outlets 110 installed, and the power supply status indicator lamp 120 may naturally be provided in a form of use in which a plurality of power supply status indicator lamps are installed, and is provided for indicating the corresponding AC power outlet 110 causing leakage to the user, thereby achieving the effect of finding the source of leakage and the location of the problem, and ensuring electrical safety. The manual leakage current interrupter switch 122 can also be provided for the user to manually stop the transfer of commercial power to each AC power outlet 110 when leakage current or pseudo leakage current occurs, thereby allowing the user to detect, maintain, or replace the outlet tap, and further achieving the effect of ensuring electrical safety and the effect of protecting life and property.

[0017] <Fourth Example> In addition, in another embodiment of the present invention, the housing 10 is further provided with a connection cord 101, which is electrically connected to the connection plug 100 and the power supply module 11 as shown in Fig. 6, so that when the connection plug 100 is inserted into a wall outlet for connection, the connection cord 101 transmits power from the commercial power source to the power supply module 11 for power supply. Thus, by installing the connection cord 101, the present invention can again provide a certain extensibility and adjustability of the power supply range under a safe power supply situation that provides an automatic leakage current interruption function and an automatic overload interruption function, thereby again improving the market adaptability, practicality and practical satisfaction of the product.

[0018] <Fifth Example> Please refer to Fig. 7 and Fig. 8. Fig. 7 and Fig. 8 are respectively a perspective view and a side view of a fifth preferred embodiment of the present invention. As shown in the figures, a movable connection conversion outlet tap 1 with an automatic earth leakage cutoff function and an automatic overload cutoff function includes a power supply module 11, a connection cord 101, an earth leakage monitoring and control module 12, and an overload monitoring and control module 13. The power supply module 11 is connected to one end of the connection cord 101, and the earth leakage monitoring and control module 12 and the overload monitoring and control module 13 are wrapped in a case 10 and connected to the other end of the connection cord 101. Reinforcing structures 1010 are provided at both ends of the connection cord 101, respectively, and the reinforcing structures 1010 are made of a tough material, and each of the connection cords 101 serves to reinforce the assembly strength between the power supply module 11 and the case 10, so that the connection cord 101 can avoid breakage damage and shortened service life caused by constant bending and twisting during practical use.

[0019] The power supply module 11 is provided with at least one AC power socket 110, the earth leakage monitoring and control module 12 is provided with a connection plug 100, a power supply state indicator lamp 120, a manual power restoration switch 121, and a manual earth leakage breaker switch 122, and the overload monitoring and control module 13 is provided with an overload protection switch 130. The power supply module 11 is electrically connected to the earth leakage monitoring and control module 12 and the overload monitoring and control module 13, and the earth leakage monitoring and control module 12 is plugged into an external wall outlet via the connection plug 100 to receive power from a commercial power source, and is used to transfer and output power from the commercial power source transported to the power supply module 11 via a connection cord 101 to the AC power socket 110.

[0020] The earth leakage monitoring and control module 12, when it learns the commercial power supplied from the AC power socket 110 by monitoring and control, drives the power supply status indicator lamp 120 to emit an indication light, and at the same time detects the current usage state of the AC power socket 110, and when the state is abnormal, closes the operation of the power supply module 11 to stop the power transfer from the commercial power to the AC power socket 110, drives the power supply status indicator lamp 120 to emit an alarm light, and the manual power restoration energization switch 121 is used to restore the power transfer from the commercial power to the AC power socket 110 by manually pressing it. In addition, the overload monitoring and control module 13 monitors and measures the current usage state of the AC power socket 110, and when the current usage amount exceeds the rated value, closes the overload protection switch 130 to stop the power transfer to the AC power socket 110. When in a no-load state, the manual leakage current breaker switch 122 can be manually pressed to change the movable connection conversion outlet tap 1 from a power supply state to a cut-off state. At this time, if it is observed and detected that the power supply state indicator lamp 120 has not switched from the indication light to the warning light, it indicates that the leakage current monitoring and control module 12 has failed.

[0021] The modules of the present invention described above are realized using a hardware method or a method of adding software to hardware. For example, the definitions of the power supply module 11, leakage current monitoring and control module 12, and overload monitoring and control module 13 essentially refer to the technical characteristics of the integration of various hardware equipment such as a CPU, a microprocessor, a memory, a signal transmitter, etc. [Explanation of symbols]
