Referring to fig. 2 to 4, a wire harness fixing bracket 10 according to a preferred embodiment of the present invention includes a main body portion 1 and a connecting portion 2, the main body portion 1 being provided with a plurality of wire harness fixing structures to be able to fix wire harnesses 20, respectively; the connection portion 2 may be connected to a connection base, such as a vehicle body. Thereby, when the connection part 2 is connected to the connection base, the plurality of wire harnesses 20 are fixed to the connection base.

Thus, in a narrow installation space such as an a-pillar of an automobile, the plurality of harnesses 20 can be simultaneously fixed by the harness fixing bracket 10 of the present invention. According to the vehicle body structure of the installation position, the shape of the wire harness fixing support 10 can be properly set, for example, the wire harness fixing support extends along the extension direction of the inner surface of the sheet metal part, so that the arrangement of the wire harness 20 can be more reasonable, and the installation space is saved. Meanwhile, a small number of holes can be formed in the sheet metal part and used as connection points for connecting the connection parts 2 of the wire harness fixing support 10, so that the problems that structural strength is weakened due to excessive holes (for connecting wire harness connectors respectively) and the like are solved. It can be understood that the connecting base body for connecting the wire harness fixing bracket can be sheet metal parts such as an A column, a front wall, a side wall and the like of an automobile.

In the wire harness mounting structure shown in fig. 2, a plurality of wire harness connectors 30, respectively, a first wire harness connector 31, a second wire harness connector 32, and a third wire harness connector 33, to which the wire harnesses 20 are respectively connected, are mounted on the wire harness fixing bracket 10, so that the wire harnesses 20 are fixed to the wire harness fixing bracket 10 and are further fixed to the vehicle body by the wire harness fixing bracket 10. The wiring harness 20 may be a main wiring harness or a branch of wiring harness extended from the main wiring harness. Further, a part of the wire harness 20 in the illustrated preferred embodiment is directly fixed to the wire harness fixing bracket 10. This will be described in detail below with reference to preferred embodiments of the utility model.

For convenience of description, two side surfaces of the main body portion 1 of the wire harness fixing bracket 10 of the present invention are defined as a first side surface 11 and a second side surface 12, respectively, wherein the first side surface 11 is for facing the connection base, and the second side surface 12 is a side surface opposite to the first side surface 11 facing away from the connection base.
