[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a housing device using claw fitting, and more particularly to a method for releasing claw fitting.

[0002]

2. Description of the Related Art In recent years, most housing devices use resin as a material, and screws are often used for assembling the housing. In places where screws cannot be tightened due to the arrangement or the like, it is often seen that they are assembled using claw fitting.

[0003] An example of the above-mentioned conventional housing device will be described below with reference to the drawings. FIG. 4 shows an example of a conventional housing device having screw fastening and claw fitting. In FIG. 4, 11-casing A and 12-casing B are 3
-The four boss portions respectively formed so as to face each other with screws are tightened and fixed. At the same time, in the lower part of the housing (outside the visible range as a product), the 13-jaws formed on the 11-housing A and the 14-holes facing the 13-jaws formed on the 12-housing B are fitted and fixed. ing. 11-Case A
And when removing 12-case B, remove the 3-screw and push 13-claw through 14-hole at the bottom
-The connection with the hole is released. In the case where the 9-claw fitting portion can be formed only in the upper portion of the housing as shown in FIG. 5, the 9-claw fitting portion cannot have the 14-hole as shown in FIG. When separating the housings A and 12-the housing B, a method of applying a force (F) to the housing outer periphery to release the 9-claw fitting portion to bend and separate the housings. Is used.

[0004]

However, the above-described method of providing the 14-hole in the 9-claw fitting portion is not provided in the visible range of the product, and the claw fitting is performed by bending the outer casing. In the method of releasing the engagement, there is almost no gap between the 9-claw fitting portions because the original purpose of the claw fitting is to fix the housing, and it is natural that the claw fitting is hard to be disengaged. There has been a problem that the appearance is impaired, such as breakage, or the serviceability is poor.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide a method for easily releasing the engagement of the claws while maintaining the same effect as before.

[0006]

In order to solve the above-mentioned problems, in the housing device of the present invention, a push-up portion substantially abutting on the vicinity of the claw tip portion is provided integrally with the housing on which the claw is not formed. Things.

[0007]

According to the present invention, when one of the housings is rotated in a direction to open each other with a part of the contact point between the housings as a fulcrum when the housings are separated, the claw pushing portion moves near the claw tip. By pushing up, the claw fitting portion is released, and the two housings can be separated.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG.
This will be described in detail with reference to FIG.

FIG. 2 is an overall sectional view of the housing device according to the embodiment of the present invention. In FIG. 2, 1-casing A and 2-casing B are substantially box-shaped (not shown), and are combined with each other. The middle and lower parts of the housing are fixed by tightening 4-boss portions formed so as to face each other with 3-screw. The upper part of the housing is fitted with and fixed to the 6-claw provided on the 1-casing A, facing the 5-hole for claw fitting provided on the 2-casing B. At this time, FIG.
As can be seen from the above, an 8-claw push-up portion is formed in the 2-case B so as to substantially abut on the vicinity of the 7-tip of the 6-claw of the 1-case A when the two cases are combined. ing. The operation of releasing the claw engagement of the housing device configured as described above will be described below.

When separating the combined housings as shown in FIGS. 1 and 2, first remove the 3-screw. Next, 1-
One of the housings is rotated in a direction in which the housing A and a part of the contact point of the housing 2 and a part of the contact of the housing B are opened as a 10-fulcrum (arrow D in FIG. 3). At this time, the vicinity of the 7-tip of the 6-claw is pushed up by the 8-claw push-up section of the casing B, so that the 9-fitting section of the 6-claw and the 5-hole follows the rotation of the casing. When gradually disengaged and completely disengaged, the two housings are separated.

As described above, according to the present embodiment, the nail push-up portion is formed on the housing B so as to substantially abut on the vicinity of the tip of the fitting nail of the housing A, and either of the housings is connected to each other. By rotating in the opening direction, the vicinity of the claw tip is pushed up by the claw push-up portion, and the claw fitting portion is released.

[0012]

According to the present invention as described above, a fitting claw is provided on one of the two combined housings, and a hole for fitting the claw from the other housing and a vicinity of the claw tip are provided. By providing a claw pushing portion that is substantially in contact with each other, when the housings are separated, by rotating one of the housings in a direction to open each other, the vicinity of the claw tip is pushed up by the claw pushing portion, and the claw fitting is performed. Because the joints are released, there is no need to make a hole in the housing outline, and there is no need to forcibly bend the housing outline. can do.
