Abstract

Provided is a waterproof structure, wherein space within a case can be water-proofed for sure, and damages to connectors can be avoided. In a structure, wherein a connector (1) fixed to a mounting hole (11a) of a metal case (11) of a motor mounted onto an automobile, and a connector (2) fixed to a mounting hole (12a) of a metal case (12) of an inverter are intermeshed, a waterproof structure (100) that waterproofs the space within each of the cases (11, 12) is provided with: a circular first packing (8a) installed at an overlapping section (35) of the case (11) and the connector (1), and between faces of the case (11) and the connector (1) that intersect with the intermeshing direction (Y), and which surrounds the mounting hole (11a) and keeps the gap between the case (11) and the overlapping section (35) watertight; and a circular second packing (8b) installed between the faces of the case (12) and the connector (2) that are parallel to the intermeshing direction (Y), and on the outer circumference face of a mounting-hole inserting-through section (62) of the connector (2), and which keeps the gap between the mounting-hole inserting-through section (62) and the inner circumference of the mounting-hole (12a) watertight.

Description

technical field

[0001] The present invention relates to, for example, in a structure in which a connector fixed to the case of one electronic device and a connector fixed to the case of the other electronic device are directly fitted together, to the inside of the case and the inside of the connector. Waterproofing structure to perform waterproofing. Background technique

[0002] Cars are equipped with various electronic devices. Wire harnesses have traditionally been used to connect these electronic devices to each other. The wire harness refers to a component composed of a plurality of electric wires and a plurality of connectors attached to ends of the electric wires. And these electronic devices are connected to each other by connecting each connector of this wire harness to each connector fixed to the case etc. of each electronic device.

[0003] On the other hand, in recent years, such as image 3 as well as Figure 4 As shown, for reasons of cost and assembly work...
