In response to the working requirements of high performance and high temperature environment, the cable assembly for transmitting signals needs to be capable of working normally at 450 ℃ for 30 min. In order to meet the requirement of high-temperature environment, the cable assembly needs to select a lead with high-temperature resistance and a high-temperature-resistant connector. Therefore, the assembly of the wires with the connector becomes a critical factor in the fabrication of the high temperature resistant cable assembly.
The high-temperature wire capable of bearing 450 ℃ is fully called a silver-plated copper core polyimide glass fiber combined insulated wire cable, and the composition structure of the wire cable is that a silver-plated soft round copper wire is used as a wire metal core 1, an outer layer is provided with an insulating layer 2 formed by wrapping a layer of polyimide composite film, and an outer layer is a layer of fluorine-plated glass fiber braided layer 3 formed by braiding glass fibers and sintering at high temperature, so that the wire is protected against heat. Compared with the common lead, the lead is externally provided with a plurality of heat insulation layers for meeting the use requirement of the lead for resisting high temperature of 450 ℃ for not less than 30 min. The high temperature wire structure is shown in fig. 1.
When the high-temperature conducting wire is matched with the connector, the end of the conducting wire needs to be processed, the end of the high-temperature resistant fluorine-plated glass fiber braided layer needs to be cut to a certain length according to the assembly of the high-temperature resistant fluorine-plated glass fiber braided layer with the connector, and when the end-cut glass fiber is sent into the connector or in the assembly process, the end of the fiber braided layer is easy to scatter, and the fiber braided layer is not easy to be successfully sent once when the fiber braided layer is matched with the connector. Through multiple operations, the braided end is scattered and easy to retract backwards, and the scattered end does not completely cover the lead, so that the high-temperature resistance of the lead is weakened; if a gluing anti-scattering measure is taken for the end of the fiber braided layer, the glue solution can be carbonized at high temperature to generate colloidal particles to form surplus substances in the using process, therefore, an effective assembling method is urgently needed to be found to ensure that the fluorine-plated glass fiber braided layer of the high-temperature-resistant lead can be successfully installed in the connector at one time, and the end of the fluorine-plated glass fiber braided layer is not deformed, so that the fluorine-plated glass fiber braided layer can effectively protect the lead in a high-temperature environment, and the high-temperature resistance of the cable assembly is improved.
