The switching socket 920 according to the embodiment of the present invention includes a housing 100, an electrical pin 200, a pin conductor 300, a temperature sensing device 400, and a response device 800.

Further, as shown in fig. 1 and 2, the temperature sensing device 400 includes a temperature sensing probe 410, and the temperature sensing probe 410 is used for directly or indirectly sensing the temperature of the electrical pin 200.

In an exemplary embodiment of the present invention, the temperature sensitive probe 410 is located within the housing 100 and is in contact with the pin conductor 300.

In another exemplary embodiment of the present invention, the temperature sensitive probe 410 is located outside the housing 100 and is in contact with the electrical pins 200.

The temperature sensing device 400 includes a temperature sensing probe 410, and a thermistor may be used as the temperature sensing probe 410. Because the pin conductor 300 is connected to the electrical pin 200, the temperature of the pin conductor 300 and its vicinity (e.g., the temperature of the inner wall surface of the housing 100 in the vicinity of the pin conductor 300 or the air in the vicinity of the pin conductor 300) can indirectly reflect the operating temperature of the electrical pin 200, and the temperature of the vicinity of the electrical pin 200 (e.g., the temperature of the inner wall surface of the housing 100 in the vicinity of the electrical pin 200 or the air in the vicinity of the electrical pin 200) can indirectly reflect the operating temperature of the electrical pin 200.

Accordingly, the temperature sensing probe 410 may be disposed within the housing 100 to indirectly sense the temperature of the electrical pin 200 by contacting the pin conductor 300, or may be spaced from the pin conductor 300 to indirectly sense the temperature of the electrical pin 200 by sensing the temperature of the area proximate the pin conductor 300.

The temperature sensing probe 410 is arranged in the shell 100, and the shell 100 can protect the temperature sensing probe 410 against water, moisture, impact and the like, so that the use reliability and the service life of the temperature sensing probe 410 can be improved; on the other hand, the conversion socket is also beneficial to simplifying the appearance of the conversion socket.

The temperature sensing probe 410 is arranged outside the shell 100, so that the distance between the temperature sensing probe 410 and the electric pin 200 can be shortened, and the sensing precision of the temperature sensing probe 410 can be improved.

In an embodiment of the present invention, further, as shown in fig. 1 and 2, the temperature sensing device 400 further includes a connecting wire 420. One end of a connection wire 420 is connected to the temperature sensing probe 410, and the other end of the connection wire 420 is connected to the responding unit 800. The temperature sensing probe 410 is bonded and fixed to a member that contacts the temperature sensing probe 410.

In an exemplary embodiment, the temperature sensitive probe 410 is adhesively secured to the pin conductor 300 by means of an adhesive.

In another exemplary embodiment, the temperature sensitive probe 410 is adhesively secured to the inner wall surface of the housing 100 in the vicinity of the pin conductor 300 by gluing.

Of course, the specific form and fixing manner of the temperature sensing device 400 is not limited thereto. For example, the temperature sensing device 400 may be electrically connected to the responding device 800 in a wireless connection manner such as WIFI, bluetooth, or infrared, and perform signal interaction.

The pin conducting member 300 includes two elastic conducting members 310, and when the plug 9102 is inserted into the electrical receptacle 112, the elastic conducting members 310 are elastically deformed, so that the plug 9102 is inserted between the two elastic conducting members 310, clamped and fixed by the two elastic conducting members 310, and electrically connected. The elastic conductive member 310 includes a clamping portion 3102 and a connecting portion 3104, the two clamping portions 3102 are used for clamping the plug 9102 and electrically connecting with the plug 9102, and the connecting portion 3104 is electrically connected with the electrical plug 200, so that the electrical plug 200, the pin conductive member 300 and the plug 9102 are electrically connected.

Compared with the clamping portion 3102, the connecting portion 3104 has a smaller amount of elastic deformation in the using process, even the elastic deformation can be ignored, so that the temperature sensing probe 410 is contacted with the connecting portion 3104 of the elastic conductive member 310, the position stability is higher, and the situations of displacement, shaking and the like are not easy to occur, thereby being beneficial to improving the use reliability of the temperature sensing probe 410.
