Description

[Detailed Description of the Invention] The present invention relates to a device for attaching a heat sink to a car stereo amplifier or the like.

Car stereo amplifiers need to be made compact as a whole, so the internal mechanism is required to be simple. Conventionally, the radiator 21 is placed on the chassis side, such as the bottom plate 22 or side plate 23, as shown in Figure 1. When installing the heat radiator 21, it is common to screw the front and rear or top and bottom of the heat radiator 21.

For this reason, not only does it require a large number of assembly steps, but also the internal arrangement of parts is often restricted due to the protrusion of the tips of the screws.

The present invention solves the above-mentioned conventional drawbacks, and provides a radiator mounting device that can minimize the number of screwed parts, is easy to assemble, and allows the radiator to be installed accurately and easily. The purpose is to

An embodiment of the present invention will be described below based on FIG. 2.

In the figure, reference numeral 1 denotes a heat radiator, and fitting grooves 2 and 3 are formed vertically and oppositely on the back side.

Further, a supporting step portion 4 is formed at the lower rear end.

Reference numeral 5 denotes a bottom plate, which has a notch 6 formed on the minus side for attaching the radiator 1, and a support 7 corresponding to the support step 4 formed on one side of the notch edge. The lower part of the rear end of the radiator 1 is supported by the radiator 1.

Reference numeral 8 denotes a fitting piece formed on the other side of the notch end edge so as to fit into at least one of the upper and lower fitting grooves 2 and 3 at one side edge of the upper heat radiator 1. and
In the illustrated example, a portion of the remaining piece of the bottom plate 5 is bent into a step shape and fitted into the fitting groove 3 on the lower side.

Reference numeral 9 denotes a side plate, and a mounting piece 1 formed on one side edge of the bottom plate 5.
The end of this side plate has a fitting groove 2 on the other side edge of the radiator 1.
3 are formed.

According to the radiator mounting device of the present invention, the radiator is supported by the support portion formed on the bottom plate, and a fitting piece formed on the bottom plate is formed on the back side of the radiator from one side edge of the radiator. Fit the two fitting pieces formed on the side plate into the upper and lower fitting grooves on the other side of the radiator, and in this state attach the side plate to the bottom plate to ensure that the radiator is properly installed. Not only is it easy to install and assemble, but the radiator itself does not require any screws, so the tips of the screws do not protrude, and there are no restrictions on the placement of components on the bottom plate, etc. There is no risk of receiving it.

In this way, the heat radiator can be attached when the side plate is attached to the bottom plate, etc., and the number of man-hours required for attaching the radiator is not particularly required, so that the number of assembly man-hours can be significantly streamlined.

In particular, in the present invention, since a notch is formed in the bottom plate for arranging the radiator, it is advantageous in terms of placement space. The fitting piece that fits into either the upper or lower fitting groove on the back side of the radiator is formed by bending the edge of the notch, and fits into the upper or lower fitting groove on the other side edge of the radiator. The two fitting pieces that fit together are formed by bending the edges of the side plates to be attached to the bottom plate, so the structure is simple, and these supporting parts and fitting pieces can be formed during the punching process of the bottom plate and side plates. As a result, it is possible to achieve a significant cost reduction, and is ideal as a mounting device for a heat sink such as a car stereo amplifier, which requires miniaturization of the internal structure of the device.
