Abstract

The utility model relates to the technical field of BMS signal acquisition wire harnesses, in particular to a new energy automobile BMS signal acquisition flame-retardant wire harness structure which comprises a BMS signal acquisition wire harness and a wire harness flame-retardant structure body, a flame-retardant corrugated pipe is arranged on the wire harness flame-retardant structure body, and hard end pipes are integrally arranged at the two ends of the flame-retardant corrugated pipe respectively. A first cable positioning seat and a second cable positioning seat which are clamped with each other are further arranged on the wire harness flame-retardant structure main body, and the first cable positioning seat is formed by rotationally connecting two symmetrical structures. The new energy automobile BMS signal acquisition flame-retardant wire harness structure can reliably fix the part, between the connectors, of the wire harness, the flame-retardant corrugated pipe is adopted for external overall protection, meanwhile, the center protection hose with the heat conduction function is arranged on the inner side of the flame-retardant corrugated pipe, cooling protection treatment can be assisted for the wire harness, and the service life of the wire harness is prolonged. Mutual interference among the wire harnesses is effectively avoided, and the flame-retardant effect is improved.
