[0002] Connector, or CONNECTOR. It is also called connector, plug and socket in China. Generally refers to an electrical connector. It is a device that connects two active devices to transmit current or signals.

[0003] Thermocouple is a commonly used temperature measuring element in temperature measuring instruments. It directly measures temperature and converts temperature signals into thermoelectric potential signals, which are then converted into the temperature of the measured medium through electrical instruments (secondary instruments). The appearance of various thermocouples is often very different due to needs, but their basic structure is roughly the same. They are usually composed of main parts such as hot electrodes, insulating sleeve protection tubes and junction boxes, and are usually used in conjunction with display instruments, recording instruments and electronic regulators.

[0004] Furthermore, thermocouples are used for temperature measurement of connectors, but existing thermocouples have certain shortcomings when used. For example, the thermocouple needs to be connected to a temperature measuring instrument during use, and then the connecting ends are connected, and a connecting wire is provided between the connecting ends. However, the length of the connecting wire is uncontrollable, resulting in a connecting wire that is too long to swing, which in turn causes the thermocouple to shake and affects normal use, further reducing the measurement accuracy of the thermocouple.

[0007] As a preferred thermocouple assembly of the utility model, the bolt is threadedly connected to the recessed block, and two bolts are provided and are symmetrical about the center line of the recessed block.

[0008] As a preferred embodiment of the thermocouple assembly of the utility model, the two bolts are fitted with two sides of the butt end through a recessed block.

[0011] As a preferred thermocouple assembly of the utility model, the movable rod is elastically connected to the through hole through a spring, and the size of the movable rod is adapted to that of the through hole.

[0012] Compared with the prior art, the beneficial effects of the utility model are:
