2. Description of the Related Art A light bulb socket housing 51 as shown in FIG. 6 is conventionally known. This housing 51
Is composed of a holding portion 53 for accommodating an ordinary bottomed cylindrical porcelain socket 52 and a plate-shaped fixing portion 54 for fixing to a panel P or the like. When attaching the socket 52 to the holding part 53, the through hole 55 at the bottom of the socket 52 and the holding part
The bottom of 53 is aligned with the slightly smaller diameter hole 56 and is generally fixed with wood screws or the like. Next, the housing 51, to which the socket 52 is attached, is attached to the attachment hole H of the panel P or the like by the holding portion
53 is fitted and fixed to the panel P by fixing it with wood screws, bolts or nuts.
When wood screws or bolts and nuts are used, the heads of such screws are exposed on the panel surface and are unsightly. Therefore, it is usual to hide the screws by attaching a cover plate 57 or the like.

Inside the porcelain socket 52, an electrode member is attached which is connected by screwing the outer screw type base portion of the light bulb B into the socket.

[0004]

[Problems to be Solved by the Invention] The conventional housing
In the case of 51, when the socket 52 is attached to the panel P, the housing 51 in which the socket 52 is housed must be screwed to the panel P by using the fixing portion 54. In this case, since the panel P is generally made of a synthetic resin sheet and has a small thickness, it is necessary to form a wood screw receiving block (58 in FIG. 6) on the back surface of the panel P. Also, when using a bolt, it is necessary to screw a nut from the rear surface of the panel. And, as described above, the covering plate 57 is also necessary. Furthermore, the troublesome work of fastening these wood screws and bolts one by one with a screwdriver is required.

On the other hand, when wood screws, bolts and nuts are not used, it is necessary to manufacture various fixing members instead.

When the conventional housing 51 is used as described above, there are problems that the number of parts is large and the material cost is high and the mounting work is complicated.

The present invention has been made to solve the above problems, and provides an economical housing that can be mounted with one touch by simply making a simple mounting hole in a panel to be mounted. The purpose is to do.

The housing of the present invention is the same as the conventional housing 51 in that the socket made of porcelain or the like is housed and fixed in the housing.

[0011] However, according to the present invention the housing and the mounting object panel, just keep drilling the mounting holes of the simple shape of the engagement piece with a notch which can pass through the housing to the periphery, with one touch It can be worn.

That is, for a housing in which a plurality of rectangular engaging pieces 4 as shown in FIGS. 1 to 4 are formed on the outer peripheral surface of the body, the panel is slightly smaller than the outer diameter of the housing body. It suffices if a large-diameter mounting hole is bored and at least the same number of rectangular notches as the number of the engaging pieces are formed in the periphery of the mounting hole. Then, when the housing is inserted into the mounting hole so that the engaging piece passes through the notch, the flange of the housing abuts the peripheral edge of the mounting hole. Then, if the housing is rotated in the specified direction, the locking claws will reach the notches, and the restoring force will cause them to project outward.
Out of the notch and rotated 180 degrees
The locking protrusion abuts on the edge of a notch. Therefore,
The housing is rotated clockwise by the locking claws and locking projections.
Or prohibit rotation in any direction counterclockwise
Since it is stopped, it is semi-permanently fixed to the panel .

[0013]

As described above, since the housing can be attached to the panel with one touch without requiring any special parts for attachment, it is extremely economical.

FIG. 5 is an explanatory view showing a positional relationship with a mounting hole, and FIG. 5 is a sectional view showing a state where the housing of FIG. 1 to which a socket and a light bulb are fixed is attached to a panel.

In FIG. 1, reference numeral 1 is a housing, and a flange 3 is formed on the upper end of a cylindrical main body 2 so as to project to the outside. Then, the main body 2 slightly below the flange 3
Four engaging pieces protruding outward are formed on the outer periphery. A slight gap 5 is formed between the flange 3 and the engagement piece 4, and when the housing 1 is attached to the panel P as shown in FIG. You will be pinched.

Further, as shown in FIG. 1, between one of the four engaging pieces 4 and the flange 3, the engaging piece 4a extends in the circumferential direction of the main body 2. A locking claw 6 that projects outward and is oriented substantially tangentially to the outer periphery of the main body 2 is formed at a portion that is away from. This locking claw 6
When the housing 1 is attached to the panel P, the housing 1 is inserted into the attachment hole H (see FIGS. 3 to 4) of the panel P, and the rotation is stopped when the housing 1 is rotated to one side around its axis by a certain angle. It is provided in order to make it. An insertion hole 7 is formed in a portion of the main body 2 corresponding to the locking claw 6 so that the locking claw 6 is elastically retracted when pressed from the outside. In the present embodiment, the locking claw 6 is integrally formed so as to partially cut out the cylindrical wall of the main body 2 and bend it outward, but the shape is not particularly limited to this shape, and for example, an immersion hole may be formed. A separate locking claw adjacent to 7 may be fixed to the main body.

FIG. 2 shows a state in which the housing 1 shown in FIG. 1 is rotated by about 180 ° about its axis.

Between the one engaging piece 4b and the flange 3, the central axis of the main body 2 is sandwiched with respect to the locking claw 6.
A locking projection 8 that projects outward is formed at a portion that is substantially symmetrical and is disengaged from the engagement piece 4b in the circumferential direction of the main body 2. The locking projections 8 connect the housing 1 to the panel P.
It is provided to stop the rotation of the housing 1 in the direction opposite to the case of the locking claw 6 when it is attached to the.

3 to 4 show the positional relationship among the engaging piece 4, the locking claw 6, the locking projection 8 and the mounting hole H formed in the panel P. As shown in FIG. The mounting hole H of the panel P is a circular hole having a diameter slightly larger than the outer diameter of the housing main body 2, and four first notches 9 through which the engaging pieces 4 of the housing 1 can pass are formed on the peripheral edge thereof. And one of the first notches 9a
A second notch 10 through which the locking claw 6 of the housing 1 can pass is formed adjacent to. A third notch 11 through which the locking projection 8 of the housing 1 can pass is formed adjacent to the first notch 9b facing the one first notch 9a. The third notch 11 and the first notch 9b are integrated with each other to form a longer notch than the other first notches 9 (including 9a).

To mount the housing 1 constructed as described above on the panel P, the locking claw 6 of the housing 1, the second notch 10 of the panel P, the locking projection 8 of the housing 1 and the third notch of the panel P are mounted. Corresponding to 11 (at this time, the four engaging pieces 4 and the four first notches 9 inevitably correspond to each other), the housing 1 is inserted into the mounting hole H of the panel P from the bottom thereof ( (See FIG. 3). Then, when the housing 1 is rotated in the direction of the arrow C, the locking claw 6 is pressed against the peripheral edge of the mounting hole H and the housing 1 is rotated while being retracted into the recess hole 7. When the housing 1 is rotated by a certain angle, the locking claw 6 reaches the first notch 9a and projects outward due to the restoring force (see FIG. 4). At this time, as shown in FIG. 4, the locking projection 8 simultaneously contacts the edge of the first cutout 9b, so that the housing 1 can no longer be rotated in the direction of arrow C. On the other hand, move the housing to arrow D
Even if the locking claw 6 is opened outward as described above, the tip of the locking claw 6 is brought into contact with and locked to the edge of the first notch 9a, so that the housing 1 is rotated. I can't.
