Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a support for supporting a plate material such as a printed circuit board, and particularly relates to an edge support that fits onto the edge of a plate material for support.

[Conventional technology]

Generally, various types of supports are used to internally support printed circuit boards in the chassis and cases of various electronic devices.One of these supports is, for example, an edge support that fits and supports the edge of a printed circuit board. Proposed.

FIG. 5 shows a conventional edge support of this kind. This edge support 21 is entirely made of an insulating material such as resin, and its lower part is fixed with a wedge-shaped insertion part 22 and a skirt part 23. On the other hand, a guide knob 24 is provided protruding from the upper part, and a hook part 25 is formed adjacent to this guide knob 24.

This edge support 21 has a fitting part 22 fitted into a support hole 12 provided in the chassis 11 etc. to fix the support itself, while a through hole 14 provided near the edge of the printed circuit board 13 to be supported is inserted into the guide knob 24. The hook portion 25 is adapted to be fitted into the hook portion 25, and the end edge thereof is engaged with the hook portion 25.

In addition, in this edge support, the hook portion 25
By forcibly deforming the hook portion 25 outward as shown by the chain line in the figure, the hook portion 25 is released from the edge of the printed circuit board 13 and can be removed.

[Problem that the invention attempts to solve]

The conventional edge support described above supports the edge of the printed circuit board 13 by locking it to the hook portion 25, but in order to increase this supporting force, it is possible to design the hook portion 25 to have a large deforming force. , the operating force required to cause the edge to climb over the hook portion 25 when supporting the printed circuit board 13 and the operating force required to forcibly deform the hook portion 25 outward when removing the printed circuit board are both increased, resulting in improved operability. The problem is that it gets extremely bad.

Furthermore, when removing the printed circuit board, it is necessary to deform the hook portion 25 outward to release the lock from the edge, and at the same time push the printed circuit board 13 upward. If the space is narrow, this pushing up operation becomes difficult, and there is also the problem that it is difficult to quickly remove the device.

An object of the present invention is to provide an edge support that can increase the supporting force at the edge of a printed circuit board, etc., while improving the operability during support and removal.

[Means for solving problems]

The edge support of the present invention has a fixing part that fits into a support hole provided in a chassis etc. to fix and support the edge support itself to the chassis, and a transparent part provided near the edge of a plate-like member that protrudes upward to support the edge support. A guide knob inserted into the hole, a hook disposed adjacent to one side of the guide knob to engage the edge of the plate member, and a hook disposed adjacent to the other side of the guide knob to apply elastic force to one side of the plate member. It consists of a buck push part that comes into contact with the hook, and a connecting piece that connects the tip of the hook part to its base.

[Effect]

According to the above structure, the supporting force is improved by the connecting piece provided on the hook part, and the deformation of the hook part is facilitated to improve operability during support and removal, and furthermore, the push-up force from the back push part improves the support force. This makes it possible to further improve the operability of the time.

〔Example〕

Next, the present invention will be explained using the drawings.

FIG. 1 is an overall perspective view of an edge support according to an embodiment of the present invention.

As shown in the figure, the entire edge support 1 is integrally molded from a resin material or the like, and a frame-shaped main body 1a has a wedge-shaped insertion part 2 at the bottom, and a "hat" on the lower side opposite to the wedge-shaped insertion part 2. ”-shaped skirt part 3
and constitute a fixed part. Inset part 2 is stem 2
Tapered portions 2b are provided on both sides of a, and auxiliary pieces 2c are provided at both ends of these tapered portions 2b, respectively, and are fitted into the inner edge of the support hole 12 of the chassis 11 as described later.

On the other hand, a short round rod-shaped guide knob 4 is provided on the upper part of the main body 1a of the edge support 1, and a hook part 5 is provided on one side adjacent to the guide knob 4, and a buck push part 6 is provided on the upper part of the other adjacent side. are formed respectively.

The hook portion 5 is bent into a substantially inverted V shape, and a downwardly directed tip 5a of the bent portion is connected to the base portion of the hook portion 5 by a connecting piece 7. The connecting piece 7 does not have any effect when the entire hook portion 5 is deformed in the outward direction, but acts to prevent the tip end 5a from being deformed alone.

Further, the buck push section 6 is formed in the shape of a circular arc with one end supported and has a small radius, so that when the free end is pushed downward, an upward repulsive force is applied.

Therefore, according to this configuration, as shown in FIG. 2, when the tapered part 2b of the fitting part 2 is inserted into the support hole 12 of the chassis 11, the auxiliary piece 2c moves the inner edge of the support hole 12 outward. Pushing force and skirt part 3
The edge support 1 itself can be fixedly supported on the chassis 11 by the force that pushes the chassis 11 downward. This is the same as before.

When supporting the printed circuit board 13,
By inserting the guide knob 4 into the through hole 14 provided near the edge and pushing the printed circuit board 13 downward, the edge deforms the tip 5a of the hook portion 5 outward and climbs over the tip 5a. The printed circuit board 13 is secured to the hook-shaped portion and guided by the guide knob 4.
It can be supported by being sandwiched between the base of the In addition, in this supported state, an upward force is applied to the printed circuit board 13 by the back push portion 6 which has been deformed from the state shown by the chain line in the figure.
The locking force at the edge of the hook portion 5 is increased. Moreover, in the hook portion 5, the connecting piece 7
Since the deformation of a toward the outside, that is, the deformation in the direction in which the engagement is released, is suppressed, this support can be made even stronger.

On the other hand, when removing the printed circuit board 13, when the entire hook portion 5 is deformed outward by manual operation or the like, the distal end 5a of the hook portion 5 is disengaged from the edge of the printed circuit board 13. At this time, the deformation of the hook portion 5 as a whole is less affected by the presence of the connecting piece 7, so it can be easily deformed and the operability can be improved. Furthermore, at the same time as the hook part 5 is released, the printed circuit board 13 is pushed upward by the pushing force of the buck push section 6, so that the operator does not have to push up the printed circuit board 13, and the printed circuit board 13 The operability of taking out can be further improved.

Here, in the edge support of the present invention, the configuration of the fixing portion to the chassis provided at the lower part may be configured as shown in FIG. 3. This is composed of a wedge-shaped tapered part 8a provided on both sides of the stem 9 as a fitting part, and a reverse tapered part 8b following this. According to this configuration, when the fitting part is fitted into the rectangular support hole 12A provided in the chassis 11 as shown in FIG. The edge support 1 can be fixedly supported by this.

In this configuration, by adjusting the dimensions of the inversely tapered portion 8b, suitable fixation can be achieved in a wide range of thicknesses of the chassis 11. Further, in this configuration, it is also possible to omit the skirt portion.

In each of the above examples, an example in which a printed circuit board is supported has been described, but the same applies even when a plate-like member other than a printed circuit board is supported.

[Effect of idea]

As explained above, the present invention has a hook portion that engages the edge of a plate-like member on one side of the guide knob protruding from the edge support, and a hook portion that contacts one side of the plate-like member with elastic force on the other side. Since the hook parts are arranged adjacent to each other, and a connecting piece is provided to connect the tip of the hook part to its base, the support and removal of the plate-like member is facilitated by the interaction of these hook parts, the back push part, and the connecting piece. This has the effect of making it easier to improve the operability, as well as increasing the supporting force and improving the reliability of the support.
