Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrical component holder for stably fixing electrical components such as a printed circuit board and wiring to a fixed member such as a chassis or a panel at predetermined intervals, and a fixing thereof. It is related to the mechanism.

[0002]

2. Description of the Related Art Conventionally, electric parts such as a chassis, a printed circuit board, and wirings installed inside an electric device are fixed to a fixed member (for example, a chassis or a panel) of the electric device at a predetermined interval in an insulated state. Various electric member holders have been used as a means for effectively fixing the space in a device by fixing the electric member holder to the electric member holder. As such an electric member holder,
Usually, one having a holding means for holding an electric component at one end of a column having a predetermined length and a fixing portion at the other end for fixing the same to a plate member is used, which is preliminarily opened in a fixed member. The electric member holder is fixed to the fixed member by inserting and fixing the fixing portion into the fixing hole.

Specifically, for example, as shown in FIG.
Substrate 11 that is a member to be fixed to which the electrical component holder is fixed
No. 0 through the fixing hole 112 formed in advance through the substrate 1
It includes a fixing portion 130 that holds both surfaces of 10 and a holding portion 120 that is formed at a position opposed to the fixing portion 130 with a predetermined gap and that holds the electric component 118 by a predetermined method.

The fixing portion 130 is an electric component 1 of the substrate 110.
A detaining piece 116 having a bow-shaped cross section for suppressing a surface on which 18 is held (hereinafter, this surface is referred to as a "surface"); and a connecting plate 113 extending from the center of the detaining piece 116, It is formed at the tip of the connecting plate 113 and penetrates the fixing hole 112 from the front side of the substrate 110 to the back side of the substrate 110 (hereinafter, referred to as “rear surface”).
It is composed of a barbed elastic check piece 114. That is, the fixing portion 130 includes the retaining piece 116 and the elastic check piece 114 that penetrates the fixing hole 112.
By sandwiching both sides of the substrate 110, the substrate 11
It is configured to be fixed to 0.

This type of electrical component holder has a substrate 11
Since the elastic check piece 114 is projected on the back surface of the substrate 0, a space for allowing the projection to exist must be provided on the back surface side of the substrate 110, which makes it difficult to downsize the electric device. There is. In addition, such a protrusion is unsightly and significantly impairs the appearance of the electric device.At the time of performing maintenance inside the device, the worker's hand is caught and the worker is injured or the electric member thereof is damaged. There are also problems such as bending the holder. Therefore, it is desired to make the protrusion length as short as possible.

However, in this electric component holder,
Insertion of elastic check piece 114 into fixing hole 112 and substrate 11
Since the back surface of 0 is restrained by utilizing the elastic restoration of the elastic check piece 114, there is a limit in reducing the length of this portion.

Further, as a conventional example in which the length of the portion protruding to the back surface of the substrate 110 is made as short as possible, Japanese Patent Publication No. 63-
There is an electric component holder described in Japanese Patent No. 5605. As shown in FIG. 2, this electric component holder is provided with a substrate 1
10, a cap-shaped and thin elastic check piece 214 having a diameter larger than that of the fixing hole 112 formed in advance through the fixing hole 112 for suppressing the rear surface of the substrate 110, and the fixing hole 112 from the rear surface side of the substrate 110.
The elastic locking piece 215 which is restored by penetrating through the elastic locking piece 214 and is separated from the elastic check piece 214 by the thickness of the substrate 110, is interposed between the elastic check piece 214 and the elastic locking piece 215, and the fixing hole 1
The fixing portion 2 having a stepped portion 226 that fits in the fixing hole 112 as the elastic detention piece 215 is restored by penetrating the same 12.
16 and a holding portion 220 that is formed at a position facing the fixing portion 216 at a predetermined interval and that holds the electric component 118 by a predetermined method.

In this electric component holder, the holding portion 220 and the elastic check piece 21 are arranged from the rear surface side of the substrate 110 of the fixing hole 112.
4 and the stepped portion 226 are provided so as to be fixed to the substrate 110. Therefore, the substrate 110
Since the elastic check piece 214 protruding to the back surface of the substrate has only the function of suppressing the back surface of the substrate 110, there is an advantage that the length of this portion can be made extremely short.

[0009]

However, in the electric component holder described in Japanese Patent Publication No. 63-5605, the holding portion 220 must be formed in a shape capable of penetrating the fixing hole 112. . Therefore, there is a problem that the versatility of the electrical component holder is reduced. On the other hand, it is possible to change the size of the fixing hole 112 according to the shape of the holding portion 220, but in this case, the elastic restraining piece 2
There is a problem that the diameter of 16 must be increased according to the size of the fixing hole 112. Also, the fixing hole 11
Since the size of 2 also varies, the fixing hole 112
There is also a problem that the manufacturing process of is complicated. Further, there is also a problem that it is difficult to remove the once fixed electric component holder from the substrate 110.

Further, the elastic check piece 214 and the elastic restraining piece 21.
Since it is necessary to set the distance from the substrate 6 to the thickness of the substrate 110, there is also a problem that productivity is reduced. As a means for improving these, there is Japanese Patent Publication No. 7-23608, but it is not possible to completely remove the protruding portion from the back surface of the substrate, and the problem of the electrical component holder shown in FIG. 1 is still solved completely. There is no problem.

Further, recently, recycling of timber and the like has been proposed, and the ease of removing the electrical component holder has become a problem. The conventional-shaped electric component holder is completed in one direction when it is inserted and set, but it is difficult to remove it because it is necessary to remove it from the back surface of the board (chassis) when removing it. There is also a problem.

Further, when the conventional electric component holder is mounted on the substrate, it rotates about a line perpendicular to the surface of the substrate as an axis, so that it is difficult to arrange the electric components while maintaining them in a constant direction. Met. For this reason, consideration is given to the shape of the fixing hole formed in the substrate to be a polygon such as a quadrangle, and the shape of the electric component holder is also formed to correspond to the fixing hole. An object of the present invention is to solve such a conventional problem, and to fix electric components such as a printed circuit board and wiring to the fixed member without protruding to the back surface of the fixed member. Accordingly, it is an object of the present invention to provide an electric component holder which is easily attached to and detached from a member to be fixed from one direction and which has excellent versatility, and a fixing mechanism which fixes the electric component holder.

Therefore, it is possible to always maintain the electric components in a fixed arrangement direction.

On the other hand, the electric component holder 14 is attached to the mounting portion 16
In the case of removing from 0, while pushing the stepped portion 46 of the engaging claw 40 downward and pulling in the direction in which the entire electric component holder 14 is pulled out, the guide pieces 42 and 44 are deformed toward each other, The electrical component holder can be easily removed from the chassis 10. Therefore, there is an effect that the electric component holder can be easily removed from the chassis 10 in order to recycle the materials.

As described above, the electric component holder 14 according to this embodiment can be securely fixed to the chassis 10 without forming any protrusion on the back surface of the chassis 10. As a result, unlike the conventional case, a space for allowing the protrusion to exist on the back surface of the chassis 10 is not required, so that the electric device can be downsized. Further, the protrusion does not significantly impair the external appearance of the electric device, and the worker's hand is caught during maintenance of the device, and the worker is injured or the electric member holder is The risk of bending can also be solved.

Further, since the shape of the holding portion 24 can be freely set and it is not necessary to consider the plate thickness of the chassis 10, the versatility of the electric component holder 14 can be improved.
