Technical Field
[0001] This utility model belongs to the field of electrical equipment technology, and more specifically, it relates to a socket with automatic leakage detection function. Background Technology
[0002] A socket, also known as a power socket or switch socket, is a socket with one or more circuit wires that can be inserted. Various wires can be inserted through it, which facilitates connection with other circuits. The connection and disconnection of the circuit is achieved by connecting and disconnecting the wires and copper components.
[0003] Based on the above, traditional sockets only have the basic functions of connecting and disconnecting power, lacking the ability to detect and protect against leakage faults. When electrical equipment suffers insulation damage, aging wiring, or incorrect wiring, leakage can easily occur, which may not only damage the equipment but also pose a risk of electric shock to the human body, seriously threatening electrical safety. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model relates to a socket with automatic leakage current detection function. This solves the problem of existing sockets lacking the ability to detect and protect against leakage current faults. By incorporating a leakage current alarm component connected in series with the copper busbar output terminal and the live wire output terminal using a low-melting-point alloy, when a leakage current short circuit occurs in the socket, causing an increase in current power, the connecting alloy melts as the temperature rises. This, combined with the spring's reaction force, quickly triggers a switch, thus informing the socket of a short circuit. This achieves automated detection and risk warning of leakage current short circuits, avoiding the risk of electric shock due to unknown faults and ensuring electrical safety.
[0005] This utility model discloses a socket with automatic leakage current detection function, which is achieved by the following specific technical means: A socket with automatic leakage current detection function, specifically including: a fixed support frame and a leakage current alarm component; The fixed support frame has an outer shell on its top inner side, and a copper busbar is installed inside the outer shell. A ferrule is fixedly connected to the copper busbar. A leakage current alarm component is installed on the bottom inner side of the fixed support frame. The leakage current alarm component includes the following components: Fixed recess: Located at the bottom inner side of the fixed support frame, the fixed recess is fixedly connected to the two sides of the fixed recess, the opposite end of the connecting crossbar is fixedly connected to the limit protrusion ring, and the outer side of the connecting crossbar is provided with a spring; Connecting support: Located between connecting crossbars, the upper and lower ends of the connecting support are fixedly connected to the extension support plate, and the end of the extension support plate is fixedly connected to the movable slip ring. The movable slip ring is slidably installed on the outside of the connecting crossbar. At the same time, a trigger rod is fixedly connected to the side of the connecting support near the fixed recess. A connecting alloy is provided between the connecting supports, and the top of the connecting alloy is attached to the copper busbar output end at the bottom of the copper busbar through the first connecting member; The bottom of the connecting alloy is attached to the live wire output terminal via a second tandem component; A switch is provided on the side of the fixed recess, and an alarm horn is provided at the front end of the fixed recess. The alarm horn is electrically connected to the switch.
[0006] Furthermore, the connecting alloy is made of a low-melting-point alloy, while the first and second connecting components are made of brass.
[0007] Furthermore, a mounting base is fixedly connected to the opposite side of the connecting support, and the mounting base has a threaded hole.
[0008] Furthermore, the mounting base is fixedly mounted with assembly bases by screws, and the assembly bases are fixedly connected by connecting alloy.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0021] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown: This utility model provides a socket with automatic leakage detection function, including: a fixed support frame 1 and a leakage alarm component 2; The fixed support frame 1 has a housing 101 on its top inner side, and a copper busbar 1011 is installed inside the housing 101. A ferrule 1012 is fixedly connected to the copper busbar 1011. The fixed support frame 1 has a leakage current alarm component 2 on its inner bottom side. The leakage current alarm component 2 includes the following components: Fixed recess 201: Located at the bottom inner side of fixed support frame 1, fixed recess 201 has connecting crossbars 2011 fixedly connected to both sides, a limiting protrusion ring 2012 fixedly connected to one end of the connecting crossbar 2011, and a spring 2013 provided on the outer side of the connecting crossbar 2011. Connecting support 202: Located between connecting crossbars 2011, the upper and lower ends of the connecting support 202 are fixedly connected to the extension support plate 2021, and the end of the extension support plate 2021 is fixedly connected to the movable slip ring 2022. The movable slip ring 2022 is slidably installed on the outside of the connecting crossbar 2011. At the same time, a trigger rod 2023 is fixedly connected to the side of the connecting support 202 near the fixed recess 201. A connecting alloy 2042 is provided between the connecting supports 202. The top of the connecting alloy 2042 is attached to the copper bus output end 2063 at the bottom of the copper bus 1011 through the first connecting member 2064. The bottom of the connecting alloy 2042 is attached to the live wire output terminal 2074 via the second cascading component 2073; A switch 205 is provided on the side of the fixed recess 201, and an alarm horn 2051 is provided at the front end of the fixed recess 201. The alarm horn 2051 is electrically connected to the switch 205.
[0022] The connecting alloy 2042 is made of a low-melting-point alloy, while the first tandem component 2064 and the second tandem component 2073 are made of brass.
[0023] When a short circuit occurs in the socket, causing an increase in current, the temperature rises. Since the melting point of the connecting alloy 2042 is low, it melts and breaks, causing the spring 2013 to lose its constraint. Under the reaction force, the spring 2013 pushes the movable slip ring 2022. The movable slip ring 2022 moves synchronously with the connecting support 2022 through the extension plate 2021, which in turn drives the trigger rod 2023 to contact the switch 205. As a result, the alarm horn 2051 sounds, promptly informing the user of the short circuit in the socket and preventing the risk of electric shock.
[0024] Example 2: Based on Example 1, wherein, as Figures 2 to 6 As shown, a mounting base 203 is fixedly connected to the opposite side of the connecting support 202, and a threaded hole 2031 is provided on the mounting base 203.
[0025] Mounting base 203 is fixedly mounted with mounting base 204 by screws 2041, and connecting alloy 2042 is fixedly connected between mounting bases 204.
[0026] The bottom of the outer casing 101 is fixedly connected to a first connecting seat 206. A first through groove 2061 is provided on the first connecting seat 206, and a first clamping bolt 2062 is installed on the first connecting seat 206. At the same time, the first connecting member 2064 and the copper bus output end 2063 are placed in the first through groove 2061 and are clamped together by the first clamping bolt 2062.
[0027] A second connecting seat 207 is fixedly connected at the bottom middle of the fixed support frame 1. A second through slot 2071 is provided on the second connecting seat 207. At the same time, the second connecting member 2073 and the live wire output end 2074 are pressed and attached by the second clamping bolt 2072.
[0028] When the connecting alloy 2042 melts, the first clamping bolt 2062 and the second clamping bolt 2072 need to be loosened to disconnect the series path between the copper bus output terminal 2063 and the live wire output terminal 2074. Then, use a screwdriver to turn the screw 2041 to remove it from the mounting base 203. During installation, the first series component 2064 and the second series component 2073 of the connecting alloy 2042 should be reattached to the copper bus output terminal 2063 and the live wire output terminal 2074, respectively. Then, tighten the first clamping bolt 2062 and the second clamping bolt 2072. Then, slide the connecting support 202 to bring the mounting base 203 closer to the assembly base 204. At this point, install it with the screw 2041 to restore the alarm function.
[0029] The specific usage and function of this embodiment are as follows: In this invention, the first series member 2064 and the second series member 2073 of the connecting alloy 2042 are respectively attached to the copper busbar output end 2063 and the live wire output end 2074. Then, the first clamping bolt 2062 and the second clamping bolt 2072 are tightened. The connecting support 202 is then slid to bring the mounting base 203 closer to the assembly base 204. At this point, it is installed using screws 2041. When a short circuit occurs in the socket, causing an increase in current and power, the temperature rises, and the connecting alloy 204... The lower melting point of component 2 causes the connecting alloy 2042 to melt, resulting in the spring 2013 losing its constraint. Under the reaction force, the spring 2013 pushes the movable slip ring 2022. The movable slip ring 2022 drives the connecting support 202 to move synchronously through the extension support plate 2021, which in turn drives the trigger rod 2023 to contact the switch 205. As a result, the alarm horn 2051 sounds, promptly informing the socket of a short circuit. This achieves automated detection and risk warning of leakage short circuits, avoiding the risk of electric shock caused by unknown faults and ensuring electrical safety.
