Abstract

PURPOSE:To reduce a component cost and to shorten an operating time by securing electronic components such as a transistor, a diode, etc., by using a leaf spring. CONSTITUTION:A leaf spring 101 is operated to suppress a heat generator 103 in a direction perpendicular to the generator. Thus, the heat of the generator is dissipated by a heat radiator 102. Electronic components such as a transistor, a diode, etc., can be easily secured by the spring. Deviation drop preventive protrusions 104, 202 improve operability of an operation and automate it.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for fixing electronic components such as transistors and diodes when they are mounted, and particularly to a method suitable for fixing a heat sink of a heat generating element.

[Conventional technology]

Conventionally, this type of method generally uses screws directly or fasteners. There are also cases where screws are abolished and they are fastened like clips.

Methods using screws tend to be expensive because there are many attached parts such as nuts and washers in addition to the screws. Furthermore, screw tightening operations tend to result in secondary costs due to tightening torque management and workability.

An embodiment of the prior art as described above is shown in FIG.

Furthermore, in the conventional technology, it has been complicated and difficult to respond to automation such as recognizing the screw position and inserting the screw due to the workability of using screws.

[Problem to be solved by the invention]

The above conventional technology uses a large number of parts and is not easy to work with, so no consideration was given to cost.

The present invention aims to reduce costs, and further aims to provide automation using robots and the like to facilitate work.

[Means to solve the problem]

In order to achieve the above objective, screws, attached parts, and fasteners were eliminated, and a plate-shaped spring was used.

Additionally, in order to improve workability and cope with automation, a protrusion is provided to prevent the leaf spring from slipping down.

[Effect]

In FIGS. 1 and 2, the leaf spring (101) is connected to the heating element (
103) in a direction perpendicular to the heating element. Thereby, the heat of the heating element is radiated from the heat radiating element (102).

In this way, electronic components such as transistors and diodes can be easily fixed using the leaf spring.

Further, the protrusions (104, 202) for preventing slipping off are important for improving the workability and automating the above-mentioned work.

〔Example〕

An embodiment of the present invention will be described below.

First, as shown in FIG. 3, the leaf spring has two stable states (a) and (b). A leaf spring with this property (
201) is set on the heat sink (102) to be fixed (state 201 in Figure 2).Furthermore, as shown in Figure 2, when the set leaf spring is pushed in the direction of the arrow, another stable state (state 201) is set. (b) in Figure 3), the heating element is pressed down with a certain amount of force.

As a result, as shown in FIG. 1, the heating element (103)
It is pressed against the heat sink (102) by the leaf spring (101).

Furthermore, in order to improve workability and automate workability, we can easily improve workability by providing a protrusion on the thing that holds the leaf spring (102 in Figures 1 and 2) to prevent it from slipping off.
Automation can be achieved.

As in the above example, by devising the structure of the leaf spring and the heat sink, it is possible to fix the heat generating element very easily, and according to this supplementary example, the improvement is significantly greater than that of the conventional technology. cost reduction can be achieved.

In this embodiment, a heating element and a heat radiating element are taken as an example, but a similar method can be applied to fixing general electronic components.

〔Effect of the invention〕

According to the present invention, compared to the prior art, it can be fixed without using screws, attached washers, washers, etc., and therefore the cost of parts can be reduced.

In addition, in the case of screw tightening, rotational movement for tightening and torque management during tightening are required, but since this is no longer necessary, it is also effective in shortening the working time.

Furthermore, since the method is simple, by adding protrusions to prevent slippage, it is possible to easily improve workability and adapt to automation.
