Problems solved by technology

In addition, when an assembly error occurs in the connector 201 or the connector 202, the connector 201 is pressed against the inverter case 12 by a greater force, and an excessive stress is generated. 201 is likely to break such a problem
[0013] In addition to these problems, in the above-mentioned waterproof structure 200, the second packing 208b may rub against the outer surface 12b of the case 12 due to the vibration of the case 11 or the case 12, and the waterproof performance of the second packing 208b may be reduced. question

Embodiment Construction

[0041] Below, refer to figure 1 as well as figure 2 , while describing the waterproof structure according to one embodiment of the present invention.

[0042] The above-mentioned waterproof structure 100 is fixed to the connector 1 in the mounting hole 11a of the metal case 11 of the motor mounted on the automobile and in the mounting hole 12a of the metal case 12 of the inverter. In the structure in which the connectors 2 are fitted, the interior of the respective boxes 11, 12 and the interior of the terminal accommodating portions 4, 61 of the respective connectors 1, 2 are waterproofed. That is, the waterproof structure 100 is a waterproof structure in a structure in which the connectors 1, 2 fixed to the boxes 11, 12 are directly fitted to each other when the inverter is mounted on the motor. In addition, "the housing 11" corresponds to "one housing" described in a claim, and "the housing 12" corresponds to "the other housing". In addition, "connector 1" corresponds t...

Abstract

A waterproof structure, which is for one connector fixed to a mounting hole of an automotive motor's metallic case and another connector fixed to a mounting hole of an automotive inverter's metallic case and connected to the one connector, comprises ring-shaped first and second packings. The first packing resides between the one case's surface and the one connector's surface that are orthogonal to a fitting direction of the connectors such that the one case's mounting hole is surrounded thereby to provide waterproof interface between the one case and the one connector. The second packing resides between the other case's surface and the other connector's surface that are parallel to the fitting direction. The second packing extends on an outer circumferential surface of the other connector to provide waterproof interface between an inner circumferential surface of the other case's mounting hole and the other connector's outer circumferential surface.

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...
