Description

Wire harness fixing bracket Technical Field The invention relates to the technical field of wire harness arrangement, in particular to a wire harness fixing bracket. Background At present, the intelligent degree of an automobile is continuously improved, such as intelligent driving, intelligent cabins, intelligent networking and other functions are gradually applied to the automobile, the number of domain controllers and cameras configured by the automobile is increased, the high-speed transmission requirements among the controllers are higher and higher, and correspondingly, high-speed transmission wiring harnesses arranged on the automobile are increased, such as hundred megaethernet wiring harnesses, gigabit ethernet wiring harnesses, video transmission wiring harnesses, antenna feeder wiring harnesses and the like. The bending radius of the high-speed transmission harness cable arrangement is required to be large so as to ensure the transmission reliability of the high-speed transmission harness cable. However, in practical vehicles, due to the limitation of the arrangement space of the vehicles, the high-speed transmission wire harness is generally arranged together with the low-voltage wire harness, and the high-speed transmission wire harness is bound with the common low-voltage wire harness during production, so that the wire harness needs to be branched during arrangement. As shown in fig. 1, the wire harness 10' leads out the first high-speed transmission line 20' to the left side of the backbone wire harness 40' and leads out the second high-speed transmission line 30' to the right side of the backbone wire harness 40', and needs to be bundled and fixed at the branching position of the wire harnesses.
