BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for electronic equipment, and more particularly, to electronic equipment for cooling a printed board mounted on the electronic equipment by air-cooling by causing a cool air to flow in the electronic equipment by driving a fan. Related to the mounting structure of.

2. Description of the Related Art Conventionally, as shown in FIG. 4, an electronic device 40 installed on a floor surface 41 via a foot 42 has a printed board 44 on which electronic components such as LSI are mounted. The electronic devices 40 are mounted over a plurality of rows, and a plurality of fans 43 are mounted on the upper surface of the electronic device 40.

By driving the fan 43, cool air is passed through the printed boards 44 from the lower direction to the upper direction in the drawing to cool the printed boards 44. A front plate 45 is attached so that cold air does not leak to the front surface.

The front plate 45 is formed with a notch 46 for inserting a tool for easily pulling the printed board 44 out of the electronic device 40. In order to drop the printed board 44 to the frame ground, it is necessary to drop it on the front plate 45 with some structure, and the role thereof is the horse terminal 47 shown in FIG.

The horse terminal 47 has a terminal 47b which is inserted into a through hole electrically connected to the ground pattern of the printed board 44, and further has a screw hole 47a for fixing the front board 45. I'm going.

Therefore, the front plate 45 and the horse terminal 47 are fastened by inserting a screw into the screw hole 47a, and the printed board 44 can be dropped to the frame ground.

[0007]

However, in the conventional structure, since the notch for inserting the tool for pulling out the printed board is formed in the front plate, cold air leaks from the notch to the outside of the electronic device. There was a problem that the cooling efficiency decreased.

Further, if foreign matter is mixed into the notch, the printed board may be damaged in the worst case. It is easy to simply prevent this notch by using another member, but it is not preferable to use another member because of the structure.

Therefore, an object of the present invention is to close the notch formed in the front plate without using a separate member.

[0010]

SUMMARY OF THE INVENTION The above-mentioned object is to mount an electronic device in which cool air is made to flow into the electronic device 1 by driving a fan 6 and a printed board 4 mounted on the electronic device 1 is cooled by air cooling. In front of the printed board 4, the front board 5 having a notch 7 for pulling out the printed board 4 is connected to the ground pattern of the printed board 4, and is fixed to the front board 5. Horse terminal 8
And a mounting structure for an electronic device, characterized in that the horse terminal 8 is formed with a barrier 8a for closing a gap formed by the notch 7.

[0011]

That is, according to the present invention, the horse terminal for dropping the printed board to the frame ground is provided with the barrier for closing the notch. Therefore, the notch of the front board can be closed without using a separate member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will now be described in detail with reference to the drawings. In addition, in FIGS. 1 to 3, the same reference numerals denote the same objects.

As shown in FIG. 1, in an electronic device 1 installed on a floor surface 2 via a foot 3, a printed board 4 having electronic components such as LSI mounted therein is spread over a plurality of rows. And a plurality of fans 6 are mounted on the top surface of the electronic device 1.
Is installed.

By driving the fan 6, cool air (shown by an arrow) is passed through each printed board 4 from the lower side to the upper side in the drawing to cool the printed board 4.
A front plate 5 is attached to each of the printed boards 4 so that cool air does not leak to the front surface thereof.

The front plate 5 is formed with a notch 7 into which a tool for easily pulling out the printed board 4 from the electronic device 1 is inserted. Printed board 4 mounted on electronic device 1
It is necessary to drop the front plate 5 with some structure in order to drop it on the frame ground, and the horse terminal 8 shown in FIG.

This horse terminal 8 has a terminal 8b which is inserted into a through hole electrically connected to the ground pattern of the printed board 4, and a screw hole 8c for fixing the front board 5 is formed. Further, a contact surface 8d that contacts the back surface of the front plate 5 is formed.

Further, a barrier 8a is formed on the horse terminal 8 at a position corresponding to the notch 7 formed on the front plate 5, and the barrier 8a allows cool air to flow from the notch 7 to the outside of the electronic device 1. You can prevent it from leaking.

2 (a) is a perspective view of the horse terminal of this embodiment, and FIG. 2 (b) is a front view thereof. Therefore, in this embodiment, as shown in FIG. 3, the front plate 5 and the horse terminal 8 are fastened to each other by inserting the screw 9 into the screw hole 8c, so that the printed board 4 can be dropped to the frame ground. In addition, the notch 7 formed in the front plate 5 can be closed by the barrier 8a provided in the horse terminal 8 while leaving a working area of a tool (not shown).

Reference numeral 10 in FIG. 3 denotes a drawing hole provided in the printed board 4, and a tool (not shown) is inserted into the hole 10 to draw out the printed board 4.

[0020]

As described above, according to the present invention, the horse terminal, which is originally used for dropping to the frame ground, is provided with the barrier for preventing cold air leakage, so that it is formed on the front plate without using a separate member. Cold air leaks from the electronic device due to the cutouts can be blocked, and the cooling efficiency is improved.
