Detailed description of the invention
Embodiments of the invention are described below in detail, and the example of described embodiment is shown in the drawings, the most from start to finish
Same or similar label represents same or similar element or has the element of same or like function.Below with reference to attached
The embodiment that figure describes is exemplary, is only used for explaining the present invention, and is not construed as limiting the claims.
The structural representation of the Wire harness protection device that Fig. 3-4 provides for the embodiment of the present invention, Fig. 5-6 is the embodiment of the present invention
The Wire harness protection device provided and the assembling schematic diagram of fire wall panel beating via, as shown in Figure 3-4, this Wire harness protection device includes
Rubber parts 1, it has the installing hole 2 passed for wire harness, and wire harness carries out tying up solid through at the bundle that ties in online after installing hole 23
Fixed.
