Description
Technical Field
[0001] The utility model relates to the technical field of electrical equipment, in particular to a switch socket with a high temperature reminder function. Background Art
[0002] The power switch socket is used to supply power to household appliances. When the power of the electrical equipment is too high, the power contact is poor, the socket is in contact with water, the line is aging, etc., the socket may short-circuit, causing the socket to burn or even cause a fire. Therefore, it is necessary to add a high temperature reminder function to the switch socket.
[0003] The patent with announcement number CN214754510U discloses a switch socket with a high temperature reminder function, which includes a first shell and a second shell, a partition is fixedly connected to the outer wall of one side of the first shell, and the partition is located between the two sockets, a mounting groove is provided on the outer wall of one side of the top of the first shell, a temperature sensor is fixedly connected to the inner wall of the mounting groove, a buzzer is fixedly connected to the outer wall of the top of the first shell, and indicator lights are fixedly connected to the outer walls at both ends of the top of the first shell, and the two indicator lights are respectively located on both sides of the buzzer, and the same sealing strip is connected between the first shell and the second shell. The utility model is provided with a mounting groove, a temperature sensor and a buzzer. When the temperature of the switch socket is too high during operation, the temperature sensor senses it and the buzzer sounds an alarm, thereby reminding people to take out the plug and maintain the switch socket, so that the switch socket has the function of high temperature reminder and the safety is improved.
[0004] However, in this socket, the temperature sensor is directly arranged on the socket. When the socket ignites an open flame due to a short circuit, the fire source is likely to directly burn the sensor or burn out the circuit connected to the buzzer, causing the sensor or buzzer to fail to work properly. Therefore, a new type of switch socket is needed to avoid this problem. Utility Model Content
[0005] In order to solve the above technical problems, the utility model proposes a switch socket with a high temperature reminder function, which can use the high temperature or open flame caused by a short circuit in the socket to trigger a buzzer for alarm, while the triggering structure and the buzzer will not be affected by high temperature or open flame.
[0006] The technical solution to achieve the purpose of the utility model is: a switch socket with a high temperature reminder function, including a shell, to which an incoming wire and an attached wire are connected, a buzzer is fixedly connected inside the shell, three terminals are fixedly connected inside the shell, a power supply component and a trigger component are arranged inside the shell, the power supply component includes a first conductive rod, a second conductive rod and a connecting wire, the first conductive rod and the second conductive rod are fixedly connected to the inside of the shell, and two connecting wires are electrically connected between the second conductive rod and the buzzer.
[0007] Preferably, the power supply assembly further includes insulating rods, a plurality of insulating rods are fixedly connected to the inner wall of the shell, and the first conductive rod and the second conductive rod are respectively fixedly connected to the plurality of insulating rods.
[0008] Preferably, the trigger assembly includes a slide and a plastic plate, the slide is slidably connected to the inner wall of the shell, the plastic plate is fixedly connected to the slide, and the plastic plate is in contact with two terminals.
[0009] Preferably, the trigger assembly further comprises a conductive sheet and a spring, wherein the conductive sheet is fixedly connected to the slide, and the spring is fixedly connected between the inner wall of the housing and the conductive sheet.
[0010] Preferably, the three terminals are respectively connected to the neutral wire, the live wire and the ground wire inside the electric wire, and the neutral wire and the live wire in the attached wire are respectively connected to the first conductive rod and the second conductive rod.
[0011] Compared with the prior art, the utility model has the following significant advantages:
[0012] In the utility model, three terminals are respectively connected to the neutral line, the live line and the ground line in the electric wires, so as to make the switch socket work normally. The plastic plate is stuck at one end of the two terminals, so that the spring cannot move the slide although it is in a compressed state. When a short circuit occurs in the socket and causes high temperature or open flame, the high temperature and open flame will melt the plastic plate. After the plastic plate melts, it becomes soft. At this time, the plastic plate can no longer play the role of being stuck at one end of the terminal. The slide will move under the action of the spring, and the conductive sheet will move at the same time. After the conductive sheet moves, it will simultaneously resist the first conductive rod and the second conductive rod. Since the first conductive rod and the second conductive rod are respectively connected to the neutral line and the live line in the attached wire, and the attached wire is externally connected to the indoor circuit, when the conductive sheet contacts the first conductive rod and the second conductive rod, the first conductive rod and the second conductive rod are connected to form a complete circuit. The buzzer in this circuit is energized and makes a sound. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] The utility model provides a switch socket with a high temperature reminder function through improvement. The technical solution of the utility model is:
[0021] like Figure 1-Figure 3 As shown, a switch socket with a high temperature reminder function includes a shell 1, an incoming wire 2 and an attached wire 3 are connected to the shell 1, a buzzer 4 is fixedly connected to the inside of the shell 1, three terminals 5 are fixedly connected to the inside of the shell 1, a power supply component 6 and a trigger component 7 are arranged inside the shell 1, the power supply component 6 includes a first conductive rod 61, a second conductive rod 62 and a connecting wire 64, the first conductive rod 61 and the second conductive rod 62 are fixedly connected to the inside of the shell 1, two connecting wires 64 are electrically connected between the second conductive rod 62 and the buzzer 4, and the two connecting wires 64 are respectively connected to the positive and negative poles of the buzzer 4, so when there is current in the second conductive rod 62, the buzzer 4 will alarm.
[0022] Furthermore, the power supply assembly 6 also includes insulating rods 63 , and a plurality of insulating rods 63 are fixedly connected to the inner wall of the housing 1 , and the first conductive rod 61 and the second conductive rod 62 are fixedly connected to the plurality of insulating rods 63 , respectively.
[0023] Furthermore, the trigger assembly 7 includes a slide 71 and a plastic plate 74. The slide 71 is slidably connected to the inner wall of the shell 1, and the plastic plate 74 is fixedly connected to the slide 71. The plastic plate 74 is in contact with two terminals 5. The plastic plate 74 is made of a polymer material with a low melting point. When a short circuit occurs in the socket, the two terminals 5 respectively connected to the neutral wire and the live wire will generate high temperature or open flames, thereby causing the plastic plate 74 to melt and soften or directly burn out.
[0024] Furthermore, the trigger assembly 7 also includes a conductive sheet 72 and a spring 73. The conductive sheet 72 is fixedly connected to the slide 71, and the spring 73 is fixedly connected between the inner wall of the shell 1 and the conductive sheet 72. The plastic plate 74 is stuck at one end of the two terminals 5. When the socket is used normally, the spring 73 is in a compressed state, and the slide 71 is restricted by the plastic plate 74 and cannot move. At this time, the conductive sheet 72 does not contact the first conductive rod 61 and the second conductive rod 62.
[0025] Furthermore, the three terminals 5 are respectively connected to the neutral wire, the live wire and the ground wire inside the electric wire 2 , and the neutral wire and the live wire in the attachment wire 3 are respectively connected to the first conductive rod 61 and the second conductive rod 62 .
[0026] The specific working method is: the three terminals 5 are respectively connected to the neutral line, the live line and the ground line in the electric wire 2 to make the switch socket work normally, the plastic plate 74 is stuck at one end of the two terminals 5, so that the spring 73 is in a compressed state but cannot move the slide 71, when a short circuit occurs in the socket and causes high temperature or open flame, the high temperature and open flame will melt the plastic plate 74, and the plastic plate 74 will become soft after melting. At this time, the plastic plate 74 will not play the role of being stuck at one end of the terminal 5, and the slide 71 will move under the action of the spring 73, and the conductive sheet 72 will move at the same time. After the conductive sheet 72 moves, it will simultaneously press against the first conductive rod 61 and the second conductive rod 62 Since the first conductive rod 61 and the second conductive rod 62 are respectively connected to the neutral wire and the live wire in the attachment line 3, and the attachment line 3 is externally connected to the indoor circuit, when the conductive sheet 72 contacts the first conductive rod 61 and the second conductive rod 62, the first conductive rod 61 and the second conductive rod 62 are connected to form a complete circuit. The buzzer 4 in this circuit is powered on and makes a sound. Therefore, when the socket generates high temperature or open flame due to a short circuit, the plastic plate 74 melts and softens, and the buzzer 4 will alarm. The actual length of the slide 71 can be appropriately extended to keep the buzzer 4 and the related circuit structure away from the fire point, that is, away from the terminal 5.

Matters not covered in the utility model belong to the common knowledge of those skilled in the art.
