Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a cover attached to a printed circuit board attached to an electronic device.

(Prior Art) Conventionally, covers have been attached to both the front and back sides of a printed circuit board for the purpose of protecting circuit components on a replaceable printed circuit board and protecting hands when installing and removing the board. Installation of such a cover is
As shown in FIG. 2, the printed circuit board 11 is fitted into the lower cover 12 by aligning the notch 11a provided in the printed circuit board 11 with the guide 12a provided inside the lower cover 12, and the printed circuit board 11 is placed on top of the lower cover 12.
An upper cover 13 was fitted to cover 1. The upper cover 13 is configured to be hung by hooking the protrusion 12a of the lower cover 12 into an opening 13a provided on its side surface or a recess (not shown). Furthermore, cutouts 15 and 16 are provided in the lower cover 12 and the upper cover 13, respectively, so as not to cover the connector 14 attached to the printed circuit board 11.

In order to attach the printed circuit board 11 to the board mounting section, the printed circuit board 11 is covered with the front lower cover 12 and the upper cover 13 to form a case and is mounted as is. It is larger in volume than the actual size of the printed circuit board, and has a special structure for attaching, detaching, and holding the board.

(Problem to be solved by the invention) Conventionally, in electronic equipment that houses a printed circuit board with a cover attached in this way, the enlargement of the printed circuit board mounting part and the specialized structure hinder the miniaturization and weight reduction of the electronic equipment. Moreover, it lowers the mounting efficiency of electronic components housed inside and becomes a factor in increasing costs. Furthermore, in the conventional cover attachment/removal structure described above, the printed circuit board is first housed in one cover, and then the other cover is fitted into this, so that it is difficult to attach/remove the cover and to remove the printed circuit board. There was a problem in that it was troublesome and time-consuming to replace.

In view of the above-mentioned problems, the present invention aims to provide a cover for a printed circuit board that allows the installation and removal of a printed circuit board in the same way as a printed circuit board without a cover, makes the board mounting part smaller and simpler, and makes installation and removal easier. It is something to do.

(Means for solving the problem) The present invention makes the width of the cover that covers both the front and back sides of the printed circuit board narrower than that of the printed circuit board, and connects the front cover and the back cover so that they can be bent at their bases. It has an integral structure, and when mounted on a printed circuit board, the shape can be changed by bending at the connecting portion so as to sandwich the printed circuit board from both sides.

(Function) According to the present invention, since the width of the cover is narrower than that of the printed circuit board, both ends of the printed circuit board that are in contact with the means for guiding and supporting the board mounting section when attaching and removing the board protrude from the cover. , the structure of the board mounting part can be made similar to the board mounting part of a printed circuit board without a cover. Furthermore, since the cover is integrally constructed and can be attached to the printed circuit board by bending the cover and holding the printed circuit board, attachment and detachment are easy.

(Example) FIG. 1 is a perspective view showing an embodiment of the present invention.

Reference numeral 1 denotes a cover that covers the upper and lower surfaces of the printed circuit board 2, and the upper cover 1a and the lower cover 1b are integrally connected by a connecting portion 3 on one side in a direction perpendicular to the printed circuit board attachment/detachment direction. There is. 4 is a protrusion provided on the lower cover 1b;
5 is a hook provided on the upper cover 1a;
The protrusion 4 passes through a hole 6 provided in the printed circuit board 2, and can be hooked onto the hook 5. 7,8
are restraining parts provided on the upper cover 1a and the lower cover 1b. The protruding portion 4, the hooking portion 5, and the restraining portions 7, 8 are in contact with the upper and lower surfaces of the printed circuit board 2, and the cover 1 attached to the printed circuit board 2
is fixed in a predetermined position and supported so that it does not move up or down.

3 is a plan view showing the cover 1 in FIG. 1 in an expanded state, FIG. 4 is a side view of FIG. 3, and FIG.
The figure is a plan view showing the printed circuit board 2 in FIG. 1.

In FIGS. 3 to 5, the protrusion 4 of the lower cover 1b has a hole 4a at its tip, and the hole 4a fits into a protrusion 5a provided on the latch 5, so that the lower cover 1b is latched. be done. The connecting portion 3 is configured to be bendable in a groove 3a provided at the base end of each of the upper and lower covers, and is fitted into a notch 9 provided in the printed circuit board 2, so that the cover 1 can be moved along with the protruding portion 4 from side to side. It is positioned so that it does not move forward or backward.

The width of the cover 1 is narrower than that of the printed circuit board 2.
The holes 6 and notches 9 of the printed circuit board 2 are also formed symmetrically on the center line of A-A'.
are also provided at the same position on the left and right corresponding to the cover 1.

Also, a connector 10 installed on the printed circuit board 2
can be connected to the printed circuit board mounting part from the opening between the two left and right connecting parts 3.

Note that the hole 6 provided in the printed circuit board 2 can be expected to have the same effect as a notch 11 as shown in FIG. 6, and can also be used as a connector 1 as shown in FIG.
It is also possible to attach the cover 1 to a printed circuit board in which 0 is provided in the opposite direction to the notch 9, and when attached to the board mounting part, the cover 1
There is no difference in the operation and effect except that the vertical direction of the two is reversed.

Next, in the configuration of the above embodiment, operations when attaching and detaching the cover to the printed circuit board will be explained with reference to FIGS. 3 to 5.

First, when attaching the cover 1, hold the lower cover 1b under the printed circuit board 2 so that the notch 9 of the printed circuit board 2 and the connecting part 3 of the cover 1 are in the same position, and then remove the lower cover 1b. Insert the protrusion 4 into the hole 6 of the printed circuit board 2. Next, by bending the upper cover 1a away from the connecting part 3 so that the connecting part 3 fits into the notch 9, and pushing the protrusion 4 into the catch part 5, the protrusion 5a of the catch part 5 is inserted into the protrusion 4. Fit it into the hole 4a and hang it. Thereby, the cover 1 is attached integrally with the printed circuit board 2 as shown in FIG.

Next, when removing the cover 1 from the printed circuit board 2, the tip of the protrusion 4 hooked to the hook 5 is pushed open in the direction of arrow B (see Fig. 3). The hole 4a is disengaged from the protrusion 5a of the latching portion 5, and if the upper cover 1a is pulled up in this state, the latching is released. Next, by pulling the lower cover 1b downward, the protrusion 4 is removed from the hole 6, and the cover 1 can be removed from the printed circuit board 2.

(Effects of the invention) As explained in detail above, according to the invention, by attaching a cover with a width shorter than the width of the printed circuit board and protruding both ends of the printed circuit board from the cover, it is possible to mount the printed circuit board. In this case, just like mounting a printed circuit board without a cover, it is sufficient to simply provide the board mounting section with guide means along both sides of the board, and therefore the structure of the board mounting section can be made smaller and simpler, and the cost can be reduced. This can be realized and the mounting efficiency of electronic devices can be increased.

In addition, the cover is an integral structure and is configured to hold the printed circuit board by bending its central part, and furthermore, the latching part that latches the upper cover and lower cover extends outside. Therefore, the cover can be easily installed and removed, and the printed circuit board can be replaced quickly.

Furthermore, since the entire cover is constructed in one piece,
Since it can be manufactured by processing a single plate or by plastic molding, it is easy to manufacture and has the advantage of being inexpensive.
