Definitions
- the present invention relates to a terminal waterproof structure for a wire harness, and more specifically, even if a grommet attached to a terminal of a wire harness routed in a vehicle is exposed to a high temperature state for a long time, the sealing performance of the grommet is not deteriorated. It is waterproof.
- the wire harness routed under the floor needs to be waterproofed, protected from stepping stones and shielded, the wire group constituting the wire harness is inserted into an exterior material made of, for example, a metal pipe, and the metal pipe is placed on the floor. Piping is fixed to the lower surface of the panel (see Japanese Patent Application Laid-Open No. 2010-21050, etc.).
- Both ends of the wire harness inserted through the metal pipe may be pulled out from the metal pipe and connected to the counterpart device as it is, but usually have flexibility such as a corrugated tube connected to the end of the metal pipe.
- both ends of the wire harness are inserted into the exterior material and routed to the counterpart device in the engine room or the rear compartment.
- a grommet 111 as shown in FIGS. 3A and 3B is attached to the terminal of the wire harness connected to the counterpart device to waterproof the terminal of the wire harness 100.

- the outer peripheral surface on the front end side is fixed by caulking with the second caulking ring 114.
- a small-diameter cylindrical portion 111b which is the other end side of the grommet 111, is externally fitted to the end of the exterior material 110 such as a corrugated tube from which the wire harness 100 is pulled out, and is tightly fixed by tape winding (T) or the like. .
- the cross-sectional shape of the cylindrical portion 116 of the shield shell 115 is generally an ellipse or an oval shape
- the large-diameter cylindrical portion 111a of the grommet 111 that covers the cylindrical portion 116 is subjected to second caulking. Even if the caulking is fixed at 114, it is difficult to load the pressure evenly, and it is difficult to improve the sealing performance. Therefore, as shown in FIG. 3B, a plurality of annular lips 112 project from the inner peripheral surface of the large-diameter cylindrical portion 111a located directly below the second caulking ring 114, and the second caulking ring 114 is fixed by caulking. At the same time, the lip 112 is pressed against the outer peripheral surface of the cylindrical portion 116 of the shield shell 115 to improve the sealing performance.

It may occur and the sealing performance may deteriorate.
- the present invention has been made in view of the above problems, and it is an object of the present invention to be able to waterproof a wire harness terminal without deteriorating the sealing performance of the grommet even when exposed to a high temperature state for a long time.

It is possible to prevent the annular seal rib from being thermally deformed even if it is exposed to a high temperature state for a long time. Further, the annular seal rib protrudes between the first caulking ring and the second caulking ring, i.e., close to the second caulking ring fixing position where a pressing force is applied, and the annular seal rib is a cylindrical portion of the shield shell.
