Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pin protection cover, and more particularly to a pin protection cover for a pin stand type printed circuit board in which pins are implanted in a required portion, and The present invention relates to a pin protection cover which, in addition to being secured, can be attached and detached extremely easily and securely.

2. Description of the Related Art Conventionally, in order to protect pins in a pin stand type printed circuit board in which pins are planted at required parts, a hole for receiving is provided for each planted pin. It has been used as a protective cover. Also, a single line socket, which is a common means in this type of technology, may be used for this purpose.
However, in such a conventional technique, since the pins implanted in the printed circuit board are inserted one by one into the corresponding holes of the protective cover or the single line socket, it is troublesome to attach and detach them. At the same time, the pins may be bent undesirably or the substrate may be damaged. It should be noted that, as the prior art of this kind, there are disclosed, for example, Japanese Utility Model Publication No. 55-122383, Japanese Utility Model Publication No. 58-196876 and Japanese Utility Model Publication No. 64.
No. 33785 can be mentioned.

[0003]

As described above, in the above-mentioned conventional technique, the pins implanted in the printed circuit board are inserted one by one into the corresponding holes in the protective cover or the like. In addition, there is a problem in that, in addition to the troublesome attachment and detachment, the pins are undesirably bent or the substrate is scratched.

The present invention has been made in order to solve the above-mentioned problems, and it is possible to receive all the remaining pins at once except the pins implanted at the end of the printed circuit board. It is intended to provide a protective cover.

SUMMARY OF THE INVENTION A pin protection cover according to the present invention is a rectangular pin protection cover for a pin stand type printed circuit board in which pins are planted at required portions, and both end portions of the board are provided. A pair of both-end pin receiving portions for receiving one pin and a multi-pin receiving portion for receiving all the remaining pins are provided.

[0006]

The pin protection cover according to the present invention is a rectangular pin protection cover for a pin stand type printed circuit board in which pins are planted at required parts, and one pin at each end of the board is provided. It is characterized in that a pair of both-end pin receiving portions for receiving and a multi-pin receiving portion for receiving all the remaining pins are provided. And since it has a configuration with such features,
There is an advantage that the attachment and detachment does not take time and that the pins are prevented from being bent undesirably and the substrate is not damaged.

1 is a schematic illustration of a pin protection cover according to an embodiment of the present invention. First, in FIG. 1A, the rectangular pin protection cover 1 is preferably made of a plastic resin having high heat resistance, and a large number of pins can be collectively received in the central portion thereof. A possible multi-pin receiving portion 2 is provided, and both end portions thereof are provided with both-end pin receiving portions 3 for receiving one pin at a leading end of a printed circuit board (not shown). . Note that FIG. 1A is a plan view when viewed from the arrow A side of FIG. 1B described later. Next, in FIG. 1B, the multi-pin receiving portion 2 and the both-end pin receiving portion 3 of the pin protection cover 1 are shown.
The seal portion 4 is provided so as to face the surface provided with. The seal portion 4 here functions as a kind of ceiling portion and has a function of protecting the pin housed in the pin protection cover 1 from an external obstacle. In addition, this (B) of FIG.
[Fig. 2] is a side view as seen from the arrow B side of Fig. 1A described above. Next, FIG. 1C is a perspective view showing the external appearance of the pin protection cover 1. Since the embodiment of the present invention has been described in detail with reference to FIGS. 1A and 1B, detailed description of FIG. 1C will be omitted.

FIG. 2 is a schematic partial modification of the pin protection cover according to the above embodiment. First, in the perspective view of FIG. 2A, a rectangular pin protection cover 1
Is preferably made of a plastic resin having high heat resistance, and a multi-pin receiving portion 2 capable of receiving a large number of pins at a time is provided in the central portion thereof.
In addition, the printed circuit board (FIG. 2) is provided on both end portions (both end portions of one diagonal line when viewed in plan from above).
(See (B) of FIG. 2)). Both-end pin receiving portions 3 are provided for receiving the pins one by one at the tip portion. Next, FIG. 1B illustrates a printed circuit board 5 to which the pin protection cover 1 described above is advantageously applied, and the pin protection cover 1 is mounted on the left side thereof. Here, the printed circuit board 5 is planted so that the pins 6 are arranged in three rows at both ends thereof. Next, FIG. 2C is a side view showing a mode in which the pin protection cover 1 is mounted on the printed circuit board 5, and FIG. 2B is a side view of the above-described FIG. It is a thing.

The above-described embodiment of the present invention and its partial modification show the embodiment in which the seal portion is provided. In order to prevent the pins from being soiled by the solder during the soldering work. While useful, this seal can be omitted if this is not a major obstacle and only prevention of pin bending is desired.

[0010]

As described in detail above, the pin protection cover according to the present invention is a rectangular pin protection cover for a pin stand type printed circuit board in which pins are planted at required portions. It is characterized in that a pair of both-end pin receiving portions for receiving one pin at both ends of the substrate and a multi-pin receiving portion for receiving all the remaining pins are provided. And since it is configured with such features, it does not take time to attach / detach, and it is possible to prevent undesired bending of the pins and damage to the board. There is an advantage that is done.
