The manufacturer provides a thermoelectric coupling gold wire, which can be fixed in the protective sleeve.

The use of thermoelectric coupling gold wire is realized through the following technical scheme:

A thermoelectric coupling gold wire comprises a wire body, a fixing component is arranged on the wire body, a protective sleeve is sleeved on the wire body, and a fixing groove embedded with the fixing component is recessed in the protective sleeve;

The fixing component comprises a variable diameter cladding sleeved on the wire body, a metal barb ring is raised on the outer side of the variable diameter cladding, and the metal barb ring is adapted to the fixing groove.

By adopting the above technical scheme, the thermoelectric coupling gold wire covers the wire body with a variable diameter cladding, which is embedded in the fixed groove on the protective sleeve through a metal barbed ring, and the variable diameter cladding is fixed in the protective sleeve, so that the wire body is not easy to fall off from the protective sleeve, and the coating between the non diameter wires can be carried out through the variable diameter cladding, It is suitable for the coating of wires with different diameters and reduces the gap between wires with different diameters and protective sleeve.
