[0038] A dew point transmitter can measure the dew point temperature in the air. It is usually used in conjunction with a display to provide real-time dew point temperature readings. In order to ensure the accuracy of the dew point temperature calculated by the dew point transmitter, the dew point transmitter needs to be calibrated regularly. When calibrating, it is usually necessary to remove the dew point transmitter from the installation position and send the dew point transmitter alone to a dedicated calibration position for calibration. At the calibration position, the calibration personnel need to externally connect a power supply and a current display device to the dew point transmitter. The power supply provides voltage for the dew point transmitter, causing a current to be generated in the dew point transmitter. The current is then displayed through the current display device, so that the corresponding dew point temperature value can be calculated based on the displayed current. In the prior art, it is usually necessary to connect the positive and negative terminals of the power supply and the positive and negative voltage terminals of the dew point transmitter to be measured through two wires respectively, and then connect the positive and negative terminals of the current display device and the positive and negative current terminals of the dew point transmitter through two wires respectively, so that the wiring process is relatively complicated. Moreover, the positive and negative voltage terminals and the positive and negative current terminals of the dew point transmitter are at the same wiring port, and the size of this wiring port is usually small, so it takes a long time to connect the wires, making the wiring process very inconvenient.

[0039] Based on the above analysis, an embodiment of the present application provides a wiring device, which is applied to a calibration system of a dew point transmitter. The wiring device of the present application will be described in detail below with reference to the accompanying drawings.

[0040] Referring to Figure 1 , it shows Figure 1 which is a schematic structural diagram of a wiring device 1 provided by an embodiment of the present application. As Figure 1 shown, the present application provides a wiring device 1, and the wiring device 1 includes: a device body 10; a wiring head 20, the wiring head 20 is electrically connected to the device body 10, and the wiring head 20 is used for electrically connecting to a dew point transmitter; a first connector 30, the first connector 30 is electrically connected to the device body 10, and the first connector 30 is used for connecting to a power supply; and a second connector 40, the second connector 40 is electrically connected to the device body 10, and the second connector 40 is used for connecting to a current display device.

[0041] In an embodiment of the present application, by providing the wiring head 20, the first connector 30 and the second connector 40, during the wiring process, the wiring head 20 is directly connected to the dew point transmitter, then the first connector 30 is connected to the power supply, and finally the second connector 40 is connected to the current display device, and the wiring process can be completed. Furthermore, there is no need to connect each component one by one through multiple wires, making the wiring process simpler and more convenient.

[0042] Optionally, the wiring head 20 includes: a conductive part 201; the conductive part 201 includes a first wiring terminal 202 and a second wiring terminal 203; the first wiring terminal 202 is electrically connected to the device body 10, and the first wiring terminal 202 is used for electrically connecting to the first connector 30; the second wiring terminal 203 is electrically connected to the device body 10, and the second wiring terminal 203 is used for electrically connecting to the second connector 40.

[0043] Specifically, the first terminal 202 can be a voltage terminal, and the voltage terminal can include a positive voltage terminal and a negative voltage terminal. The second terminal 203 can be a current terminal, and the current terminal can include a positive current terminal and a positive voltage terminal. The arrangement of the positions of the positive voltage terminal, the negative voltage terminal, the positive current terminal, and the positive voltage terminal on the wiring device 1 is the same as the setting method of the positions of the corresponding four terminals in the dew point transmitter. Multiple wires can be integrated in the device body 10. One ends of the multiple wires are respectively electrically connected to multiple terminals, and the other ends are respectively connected to the first connector 30 and the second connector 40. In this application, by arranging the first terminal 202 and the second terminal 203 on the wiring head 20, the wiring head 20 can be directly connected to the dew point transmitter, avoiding incorrect connection of the wires to the wrong port positions, and preventing mistakes and errors.

[0044] Optionally, the wiring head 20 further includes: a connection frame, the connection frame is connected to the device body 10, and the device body 10 encloses to form a receiving cavity, and the first terminal 202 and the second terminal 203 are arranged in the receiving cavity.

[0045] Specifically, the connection frame is fixedly connected to the device body 10, and the connection frame and the end of the device body 10 enclose to form a receiving cavity. Arranging the first terminal 202 and the second terminal 203 in the receiving cavity can protect the terminals and avoid damage to the wiring terminals caused by accidents such as water ingress and collision, improving the safety of the wiring device 1. The connection frame can be in the shape of a cylinder, a triangular prism, a square, etc. The embodiments of this application do not make specific limitations in this regard. In practical applications, its shape can be adapted to the interface shape of the output end of the dew point transmitter, so that the wiring head 20 can be more firmly connected to the dew point transmitter.

[0046] Optionally, the first connector 30 includes a first connection wire 302 and an adapter 301; one end of the first connection wire 302 is electrically connected to the device body 10, and the other end is electrically connected to the adapter 301, and the adapter 301 is used to connect to a power source.

[0047] Specifically, the first connection wire 302 can include a positive wire and a negative wire. One ends of the positive wire and the negative wire are respectively connected to two wires built in the device body 10, and the other ends are connected to the adapter 301. The adapter 301 is connected to the socket of the power source. The voltage provided in the power socket is usually an alternating voltage, and the adapter 301 can convert the alternating voltage into a direct current voltage required by the dew point transmitter for output.

[0048] In practical applications, by setting the adapter 301, the AC voltage output by the power supply can be converted into a DC voltage, so that there is no need to connect components for voltage conversion through wires and then connect to the dew point transmitter through wires to input the required voltage to the dew point transmitter, further making the wiring process simpler and more convenient.

[0049] Optionally, the adapter 301 is a 24V adapter 301.

[0050] In practical applications, the voltage provided by the power supply is usually 220V, while in the calibration process, the voltage that the power supply usually needs to provide to the dew point transmitter is 24V. The 24V adapter 301 directly converts the 220V voltage provided by the power supply into 24V voltage and supplies it to the dew point transmitter, so that there is no need to connect components for converting 220V voltage into 24V voltage through wires and then connect to the dew point transmitter through wires, further making the wiring process simpler and more convenient.

[0051] Optionally, the first connector 30 includes: a first connecting wire 302 and a connector; one end of the first connecting wire 302 is electrically connected to the device body 10, and the other end is electrically connected to the connector, and the connector is used to connect to the power supply.

[0052] In practical applications, the first connecting wire 302 can include a positive wire and a negative wire. One ends of the positive wire and the negative wire are respectively connected to two wires built in the device body 10, and the other ends are connected to the connector. Thus, when the power supply is a mobile power supply, the connecting wire can be connected to the mobile power supply through the connector, so that the wiring process is more convenient and simple when connecting the mobile power supply.

[0053] Optionally, the connector is a universal serial bus connector.

[0054] Specifically, the universal serial bus connector (English: Universal Serial Bus, abbreviation: USB), that is, the USB connector. Since the connector of the mobile power supply is usually a USB interface, by setting the connector as a USB connector, the first connecting wire 302 can be easily connected to the power supply, making the wiring process simpler and more convenient. And since the USB connector is a common connector, the cost of the wiring device 1 can be reduced.

[0055] Optionally, the second connector 40 includes a second connecting wire 401, the second connecting wire 401 is electrically connected to the device body 10, and the second connecting wire 401 is used to connect to the current display device.

[0056] Specifically, the second connection line 401 may include a positive wire and a negative wire. One end of the positive wire and the negative wire are respectively connected to two wires built in the device body 10, and the other ends are respectively connected to the positive terminal and the negative terminal of the current display device. Thus, the current in the dew point transmitter can be displayed on the current display device. By directly connecting the second connection line 401 to the current display device, the wiring process becomes simpler and more convenient.

[0057] As a preferred solution, the positive wire and the negative wire of the second connection line 401 may be clip wires. By clamping the clips on the positive terminal and the negative terminal of the current display device, the wiring process of the wiring device 1 is further simplified.

[0058] In a second aspect, the present application also discloses a dew point transmitter calibration system, which includes the wiring device described in any of the above embodiments.

[0060] It should be noted that in the embodiments of the present application, the structure of the wiring device is the same as that of the wiring device described in any of the above embodiments, and its beneficial effects are similar, so no further description will be given here.
