This invention relates to the field of battery testing equipment and electrical connections, specifically to an integrated assembly of current, voltage, and temperature probe harnesses for cylindrical batteries. It comprises a probe holder, a rigid conductive busbar, a flexible sampling line, a probe, a tapered heat-shrink sleeve, and a phase-change thermoplastic elastomer. The assembly constructs an inverted V-shaped suspension cavity within the glue-filling cavity of the holder. The welding joint between the sampling line and the probe tail is wrapped by the heat-shrink sleeve and fitted within this suspension cavity, with the remaining gap filled with the phase-change elastomer. Its core principle is to utilize the Joule heat generated by the conductive busbar during testing to cause the elastomer to expand and rigidly lock into place. When subjected to external tension, the tapered heat-shrink sleeve wedges into the suspension cavity, generating a centripetal clamping force. This invention cleverly combines the flexibility and high rigidity of the materials, absorbing assembly stress at room temperature and effectively blocking the transmission of stress from mechanical vibrations to the signal nodes during operation, preventing microscopic loosening of the nodes due to reciprocating motion, and greatly improving connection reliability in complex environments.
