JP2000003753A - Case for control device integrated waterproof connector - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a control device which does not limit a mounting place and improves reliability by providing a constitution that a recessed shape and a projecting shape are provided on a case side outer periphery and on a base side outer periphery, respectively, the base side projecting part is formed into a V-shape and the recessed shape and the V-shape are bonded via an adhesive. SOLUTION: When a case integrated waterproof connector 1a and a base 2a are bonded, an adhesive 4 is applied to a base V-projecting shape 2b and a recessed shape 1b of a connector is mounted so as to be covered from the upper part of the base V-projecting shape 2b. As a result, the adhesive 4 can be uniformly infilrated into the connector 1a and the base 2a. At bonding and adhesive hardening, adhesive property of the connector 1a and the base 2a can be improved by providing a constitution such that air bubbles contained in the adhesive 4 and air caught in then are exhausted from a gate-shaped air hole 5 on a connector recessed shaped side surface.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case-integrated waterproof connector for a control device, comprising a board having an electric circuit, a waterproof case for accommodating the board, and a connector integrated with the case. In particular, the present invention relates to a structure of a case-integrated waterproof connector for a control device that can cope with improving waterproofness and reliability of the control device by changing a configuration for connecting a case-integrated waterproof connector and a base and a structure for mounting a control device. .

[0002]

2. Description of the Related Art A conventional case-integrated waterproof connector for a control device is provided with irregularities on each of a case and a base, and is connected by returning an adhesive. There is no countermeasure by changing the uneven shape.

[0003]

Recently, control devices have become more sophisticated, smaller and lighter, and the operating environment and mounting locations have become more severe and complicated. In addition, as the number of substrates used for the control device has been increased, and compact and high-density mounting has been demanded, a smaller and more reliable control device has been required from the viewpoint of a mounting place. Has been requested.

[0004] It is an object of the present invention to provide a control device which does not limit the above-mentioned mounting place and has improved reliability.

[0005]

The object of the present invention is to provide a connection between a case-integrated waterproof connector and a base attached thereto.
This can be solved by changing the convex shape of the base to a V-shape to increase the connection reliability, or by returning the bolt to the case-integrated waterproof connector and the base and tightening them together.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram of a case-integrated waterproof connector 1a for a control device according to the present invention. The case-integrated waterproof connector 1a for the control device has a configuration in which a terminal 3 and a concave shape 1b are provided on the outer periphery, and the adhesive 4 is turned back to be joined to the base V-shaped convex shape 2b. When joining the case-integrated waterproof connector 1a and the base 2a, an adhesive 4 is applied to the convex shape 2b of the base V-shape, and the concave shape 1b of the case-integrated waterproof connector is covered from above the convex shape 2b of the base V-shape. With such a configuration, the adhesive 4 uniformly wraps around the joint between the case-integrated waterproof connector 1a and the base 2a.

The gate-shaped ventilation hole 5 on the side surface of the case-integrated waterproof connector 1b is used for joining the concave shape 1b of the case-integrated waterproof connector and the V-shaped convex shape 2b by turning the adhesive 4 back. The air bubbles 6 contained in the adhesive 4 and the air entrapped at the time of joining are discharged from the gate-shaped vent hole 5 on the concave side surface of the case-integrated waterproof connector, and the same applies when the adhesive is cured. An effect can be obtained, and an effect of improving the adhesion between the case-integrated waterproof connector 1a and the base 2a can be obtained.

Further, as shown in FIG. 4, the case-integrated waterproof connector 1a and the base 2 mounted with the adhesive 4 turned back.
The effect of improving the waterproofness can be obtained by returning the bolt a to the control device mounting portion 8 and tightening it together.

[0009]

According to the present invention, the waterproofness and reliability of the control device can be improved.
