Description

[Detailed Description of the Invention] The present invention relates to a communication device casing that can reduce the temperature rise inside the casing due to heat generated by a printed circuit board housed inside the casing.

In communication equipment that is made up of multiple printed boards, including printed boards mounted with high-heating electronic components such as power transistors (hereinafter referred to as high-heating printed boards), the casing is heated by the heat generated by the high-heating printed boards. It is necessary to take measures to effectively reduce the temperature rise inside the body.

The present invention is intended to achieve this, and its purpose is to provide a communication device casing that can reduce the temperature rise inside the casing due to the heat generated by a high-heating printed circuit board.

Embodiments of the invention will now be described with reference to the drawings.

In FIGS. 1 to 3, a housing 1 is composed of side plates 2 and 2', a top plate 3, and a bottom plate 4, and a backboard 6 is attached to the rear of a frame 5.

7A is a high heat generation printed board, which is inserted into the housing 1 by being guided by guide grooves 9, 9' provided in protrusions 8, 8' formed on the side plates 2, 2', and is fixed to the front end. Connector 10
is removably housed in the housing 1 by connecting it to a block connector 11 attached to a backboard 6 at the rear of the frame 5.

Note that the other printed boards 7B, 7C, . . . , 7F are similarly housed in the housing 1.

Reference numeral 12 denotes a ventilation hole provided in the protruding portions 8, 8' of the side plates 2, 2', through which hot air heated within the housing is discharged to the outside as shown by arrow lines in FIG.

As a means for reducing the temperature rise inside the housing due to the heat generated by the high heat generation printed board 7A inside the housing for communication equipment,
In the present invention, a partition plate 13 is provided.

The partition plate 13 is made of a metal plate made of aluminum or the like with good thermal conductivity and has approximately the same dimensions as the high heat generation printed board 7A.
It is inserted into the frame 5 while being guided by the guide groove 14.14' provided in the guide groove 14.14', and the portions of both ends protruding from the guide groove 14.14' are formed into protrusions 8, 8 as shown in FIG. ’ is fixed by caulking.

Therefore, the high heat generation printed board 7A is thermally partitioned into a separate room by the partition plate 13 to prevent other printed boards from being heated, and the partition plate 13 is made of a metal plate with good thermal conductivity. As a result, the number of heat dissipation paths increases, and heat is transmitted to the surroundings from this partition plate 13 as shown by the arrow line in FIG. can be reduced.

In addition, this partition plate 13 has an electrical shielding effect and can also serve as reinforcement for the casing.

As described above, according to the present invention, the high heat generation printed board is thermally separated from other parts by the partition plate made of a material with good heat conduction and connected to the side plate, so In addition to preventing the printed circuit boards from being heated, increasing the number of heat dissipation paths allows the heat generated by the high-heating printed circuit boards to be transmitted to the surroundings, reducing the temperature rise inside the casing. , it is possible to achieve effects such as reinforcing the casing.
