Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a component mounting device for mounting a component on a heat sink.

[0002]

[Prior art]

 Conventionally, when attaching parts to a heat sink, it has been the mainstream to use screws or springs. Hereinafter, a conventional component mounting device will be described with reference to FIGS. 3 and 4. As shown in FIG. 3, the component mounting device is mainly composed of a heat sink 1, a component 2, a support column 3 and a substrate 4. The heat sink 1 and the component 2 are provided with a hole (not shown) in which a common screw 5 can be screwed, and the component 2 is connected to a support column 3.

Therefore, when assembling the component mounting apparatus, the component 2 is fixed to the heat radiating plate 1 with screws, the supporting columns 3 attached to the component 2 are passed through the holes 6 provided in the substrate 4, and the heat radiating plate is attached. It suffices if the bottom part of 1 is bonded to the substrate 4, and the position of the component 2 is stabilized in this way.

In addition to this, instead of fixing the component 2 to the heat sink 1 with screws, there is one in which a fixed spring 7 is sandwiched between the component 2 and the heat sink 1 (see FIG. 3). In this case, Due to the action of the fixed spring 7, the component 2 is sandwiched and fixed between the heat dissipation plate 1 and the fixed spring 7.

[0005]

[Problems to be solved by the device]

 However, conventionally, when the component 2 is attached to the heat dissipation plate 1, since the screw 5 and the fixed spring 7 are used, the number of components is large and it is troublesome.

The present invention has been made in view of the above problems, and an object of the present invention is to realize a component mounting device which can reduce the number of components and can mount components without trouble.

[0007]

In order to solve the above-mentioned problems, a component mounting device of the present invention comprises a heat dissipation plate and an elastic fixing part integrated with the heat dissipation plate. It is possible to hold the parts by the fixing part.

[0008]

[Action]

 With the above structure, when a component is inserted between the heat sink and the fixing portion and press-fitted, the component is sandwiched and fixed by the heat sink and the fixing portion.

[0009]

【Example】

 An embodiment of the present invention will be described with reference to FIG. The same parts as those in the conventional example are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 1, the component mounting device includes a heat dissipation plate 1 and a fixing portion 8 integrated with the heat dissipation plate 1. The fixing portion 8 has elasticity and has a Z-shaped cross section.

The operation of the above configuration will be described below. First, the component 2 is inserted between the heat radiating plate 1 and the fixing portion 8 and press-fitted to sandwich the component 2 between the heat radiating plate 1 and the fixing portion 8. Next, the support pillar 3 is attached to the component 2, the support pillar 3 is passed through the hole 6 formed in the substrate 4, and then the heat dissipation plate 1 is bonded to the substrate 4. As a result, the component 2 is fixed to the heat sink 1, and the position of the component 2 is stabilized.

As described above, according to the embodiment of the present invention, when the component 2 is inserted between the heat sink 1 and the fixing portion 8 and press-fitted, the component 2 is sandwiched between the heat sink 1 and the fixing portion 8. Therefore, it is possible to mount the component 2 with a small number of parts and without trouble, and the mounting of the component 2 becomes easy.

In the present embodiment, the component 2 is inserted between the heat sink 1 and the fixed member 8 from below, so that the component 2 is sandwiched between the heat sink 1 and the fixed member 8. It suffices if the component 2 can be held by the fixing portion 8.

Further, although the fixing portion 8 has a Z-shaped cross section in this embodiment, it may have a L-shaped cross section, a two-shaped cross section, or the like.

[Effect of device]

 As is clear from the above description, the component mounting device of the present invention enables sandwiching of the component by the heat radiating plate and the fixing portion which has elasticity and is integrated with the heat radiating plate. It is possible to mount the parts without applying any force, which simplifies the mounting of the parts.
