Description

Technical Field

[0001] The utility model belongs to the technical field of thermocouples, and in particular relates to a thermocouple wiring device. Background Art

[0002] In the industrial field, many temperature measurement scenarios require the use of thermocouples for temperature measurement. When using thermocouples for temperature measurement, it is first necessary to connect the thermocouple wire to the data acquisition device. A small number of thermocouples can be directly connected to the thermocouple wire and the data acquisition device by crimping or other methods. However, when there are many temperature measurement points and different products need to be measured frequently, the connection between the thermocouple wire and the data acquisition device will consume a lot of manpower and material resources. Therefore, when thermocouples are used to measure a large number of temperature measurement points or when the measurement points need to be changed frequently, thermocouple plugs and sockets are usually used to connect the thermocouple wire to the data acquisition device.

[0003] When thermocouple plugs and sockets are used to connect thermocouple wires, the data acquisition device must first be connected to the thermocouple socket through the thermocouple wire, and then the thermocouple measurement end can be directly connected to the data acquisition device by plugging. Usually, the thermocouple socket at the end connected to the data acquisition device will directly fix a large number of thermocouple sockets through a fixing box to facilitate numbering and plugging. When the number of existing thermocouple plugs reaches a certain level, since the conductive connection part of the thermocouple plug is exposed to the outside for a long time, it is inevitable that the conductive part of the thermocouple plug will be stepped on or damaged by other means when the thermocouple plug is stored, resulting in increased maintenance costs for the thermocouple plug.

[0004] The Chinese patent publication number is CN220985055U, and the name is a patent for a thermocouple socket and a test system. It discloses a thermocouple socket and a test system, including a shell, a fixing sleeve, multiple female end bodies and multiple thermocouple wires. The shell is provided with a accommodating cavity, multiple jacks and connecting holes. The accommodating cavity is connected to the multiple jacks and connecting holes respectively. The fixing sleeve is plugged into the connecting hole. Multiple female end bodies are fixed in the accommodating cavity. One female end body corresponds to one connecting hole. The female end body is used for thermocouple plug insertion. Multiple thermocouple wires are sleeved in the fixing sleeve. One end of a thermocouple wire passes through the connecting hole and is connected to a female end body. The other end of a thermocouple wire is used to connect to a temperature data collector. Although the patent application can fix the thermocouple plug, the thermocouple plug is still exposed to the outside, and there is a risk of being stepped on and damaged. Utility Model Content
