When the second upper cover 24 is covered on the second bottom 14, the bottom latch 143 and the latch lower portion 248C are latched to each other in the latching direction, so as to prevent the first mounting portion 144 and the second mounting portion 242 from being separated from each other in the latching direction.

When the second cover 24 is covered on the second bottom 14, the bottom latch 143 can be limited between the latch upper portion 248A and the latch lower portion 248C to prevent the first mounting portion 144 and the second mounting portion 242 from moving in the latching direction. Further, the bottom latch 143 is clearance fit or transition fit with the top cover latch 248 in the latching direction.

In the example shown, the cover clip 248 is "I" shaped. The upper buckle part 248A is an I-shaped upper cross, the middle buckle part 248B is an I-shaped vertical, and the lower buckle part 248C is an I-shaped lower cross. The bottom latch 143 is a protrusion protruding from the surface of the second bottom 14 along the length direction L, and can enter between the latch upper portion 248A and the latch lower portion 248C along the length direction L.

In the utility model, the second bottom part is fixedly spliced with the first bottom part in the length direction, and the first upper cover is fixedly spliced with the first bottom part and the second bottom part in the height direction respectively, so that the assembly is convenient; after the first bottom, the second bottom and the first upper cover are assembled, the first bottom, the second bottom and the first upper cover are connected in pairs and interact with each other, the connection is reliable and stable, and the structural strength is reliable. The second upper cover is fixedly connected with the first upper cover in an inserting mode, the wire harness support is convenient to assemble, and the structural strength is reliable.

The wiring harness is connected to the engine through the wiring harness support and the foaming piece. The wire harness support can be matched with the shape of the engine knot, and the layout is attractive. But wire harness support threaded connection is on the engine, and mechanical strength is high, the dependable performance. Thereby foaming piece fixed connection forms the branch on the pencil support, and the shape of foaming piece can be walked the line demand according to the pencil and set up, and the trend is obvious, easily user installation pencil. The foaming piece has good sealing performance and beautiful appearance. The wiring harness installation structure is high in strength and reliable in performance.

The second upper cover of the wire harness support is provided with a second mounting part in a protruding mode along the length direction. The second bottom and the second upper cover of the wire harness support are provided with a bottom buckle and an upper cover buckle in a protruding mode. The bottom buckle and the upper cover buckle are mutually buckled in the buckling direction perpendicular to the length direction, the position of the second installation part in the buckling direction can be located, the second installation part is accurate in the height position location of the second bottom in the buckling direction and can be guaranteed, the position of the second installation part in the buckling direction is high, and the assembly precision of the wire harness support is high, and the assembly error is small. When the second upper cover is covered and connected on the second bottom along the length direction, the bottom buckle and the upper cover buckle automatically complete mutual buckling, and the assembly is convenient.

The wire harness support can be directly fixedly installed with the connector through the installation part, and the wire harness support can be directly fixedly installed on the engine, so that the structure is simplified, and the raw material consumption and the process cost are saved. Compact and beautiful appearance.

The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
