High-toughness wire harness

The utility model provides a high-toughness wire harness which comprises a wire core, and a protection mechanism is arranged outside the wire core. The protection mechanism comprises a buffer sleeve arranged outside the wire core in a sleeving mode and an insulating layer arranged outside the buffer sleeve in a sleeving mode. The buffer sleeve comprises extension rings which are connected to the outside of the wire core and are arranged along a linear array, and spring rings which are connected between the adjacent extension rings. According to the utility model, a buffer space can be provided for the wire harness which is extruded or bent, so that the service life of the wire harness is prolonged. 本实用新型提供了一种高韧线束，包括导线线芯，所述导线线芯的外部设有防护机构；所述防护机构包括套设于所述导线线芯外部的缓冲套，以及套设于所述缓冲套外部的绝缘层；所述缓冲套包括连接于所述导线线芯外部、且沿直线阵列设置的延展圈，以及连接于相邻所述延展圈之间的弹簧圈。本实用新型能够为受到挤压或者弯折的线束提供缓冲空间，以便于提高线束的使用寿命。
