Description

[Detailed Description of the Invention] This invention relates to a connection structure for electronic components, and particularly to a connection structure for electronic components that allows terminals of electronic components to be electrically connected without using soldering.

FIG. 1 is an illustrative view showing a conventional connection structure of electronic components, in particular, FIG. 1a shows a front view thereof, and FIG. 1 shows a sectional view viewed from the side.

When such an electronic component 1 is attached to a hard pudding and a board 2, the rear end and both sides of a plate-like member 31 made of an insulating material are provided with holes for the terminals 12 and 13 of the electronic component 1 to pass through. Legs 32, 33 extending vertically downward
．． 34 is provided, and the legs 33 and 34 of the holder 3 are fitted and fixed into holes formed in the hard printed circuit board 2, and the legs 33 and 34 of the holder 3 are fitted into holes formed in the plate-like member 31 of the holder 3. The terminals 12 and 13 of the electronic component 1 are inserted, and the tips of the terminals are inserted into the through holes punched in the hard printed circuit board 2, and are formed around the through hole punched portions of the printed circuit board 2. The electrodes and terminals 11, 12 of the electronic component 1 are connected by soldering.

Conventionally, electronic components have been connected by soldering their terminals to a hard printed circuit board, which makes it troublesome to install electronic components, and when replacing electronic components, it is necessary to remove the soldered parts. The melted compound electronic components must be connected by soldering, and at this time, the electrodes (copper foil) formed on the hard printed circuit board tend to peel off, and there is a limit to the number of times they can be replaced. Ta.

Furthermore, connection by soldering has the problem that electronic components are likely to be thermally destroyed by heat during soldering.

Therefore, this invention was made to solve the above-mentioned problems. When connecting electronic parts, it is possible to easily connect them without soldering, and moreover, the electronic parts can be easily replaced and can be repeated many times. As you can do,
The purpose is to provide a new connection structure for electronic components.

To summarize this idea, a conductive rubber member is attached to the terminal of an electronic component, and a part of the conductive rubber member is crimped and connected to a board or the like that is to be electrically connected to the terminal of the electronic component. It is something to do.

Next, the specific structure of each component used in this embodiment will be explained with reference to FIGS. 2 to 4.

The light emitting diode 1, which is an example of an electronic component, has a light emitting display section 11.
Two terminals 12 and 13 for electrical connection are formed at the lower end of the.

An electronic component holder (hereinafter referred to as holder) 4 used to attach this electronic component 1 to a hard printed circuit board 5 includes a guide 41 including a notch 42 that guides the terminal 12, 13 of the electronic component 1, and 1, and retaining parts 44 and 45 for fixing to the hard printed circuit board 5 are formed at the lower ends of both sides of the retaining part 43, and at the back surface of the retaining part 43. A positioning protrusion 47 is formed at the lower end of the side, and an arcuate cutout 4 for pressing a conductive rubber tube 6, which will be described later, is provided at the lower end of the front wall of the holding part 43.
6 is formed, and slits 4 are formed in both side wall portions of the holding part 43.
8 is formed.

Note that, preferably, the terminals 12 and 13 inside the holding part 43
A rattling prevention rib 49 is provided between the two.

The hard printed circuit board 5 is connected to the engaging portion 44 of the holder 4.
．． 45 and a positioning hole 53 for inserting and positioning the positioning protrusion 47, and a circle formed at the lower end of the front wall of the holder 4. An electrode 5 is provided in a portion corresponding to the arcuate notch 46.

FIG. 5 is an illustrative view showing how the parts shown in FIG. 4 are assembled.

Next, a case will be described in which the electronic component connection structure of this embodiment is made by assembling each component.

The electronic component 1 is inserted into the notch 42 of the holding portion 41 of the holder 4, and the conductive rubber tube 6 is attached to the terminals 12 and 13 of the electronic component 1 that have been inserted.

Then, with the conductive rubber tube 6 not attached to the terminal 12.13 bent to the position of the arcuate notch 46, the positioning protrusion 47 of the holder 4 is inserted into the positioning hole 53 of the hard printed circuit board 5. At the same time as the insertion, the engaging portion 44
．． 45 are press-fitted into the through holes 51 and 52.

Note that, as described above, since the slit 48 is formed in the holder 4, the engaging portions 44 and 4 are
5 move elastically.

As a result, the engaging portions 44 and 45 are connected to the hard printed circuit board 5.
The holder 4 is attached to the hard printed circuit board 5.
Attach to.

At this time, the bent end of the conductive rubber tube 6 is pressed by the arcuate cutout 46 of the holder 4 with current flowing directly to the electrode 54 formed on the upper surface of the hard printed circuit board 5. The terminals 12 , 13 of the electronic component 1 and the electrode 54 are electrically crimped and connected via the conductive rubber tube 6 .

A front view and a side view of the electronic component mounting structure of this embodiment assembled in this manner are shown in FIGS. 2a and 1), and a sectional view thereof is shown in FIGS. 3a and 1).

As mentioned above, in this embodiment, a conductive rubber tube is attached to the terminal of an electronic component, and the end of the conductive rubber tube is attached to a hard printed circuit board using a holder for attaching the electronic component. Therefore, it is possible to attach electronic components without soldering, and there is an advantage that electronic components can be easily replaced by removing the holder from the hard printed circuit board.

Note that the holder 4 can hold the substrate 5 due to the presence of the slit 48.
Since the holder 4 is elastically attached to and detachable from the holder 4, the holder 4 can be easily removed.

FIG. 6 is an illustrative view showing an electronic component mounting structure according to another embodiment of the invention.

In this embodiment, instead of the above-mentioned hard printed circuit board 5,
It is electrically connected to a flexible substrate 71 such as a key sheet.

When connecting the electronic component 1 to the flexible board 71,
The flexible substrate 71 is laminated with a hard material 72, or the flexible substrate 71 and the hard material 72 are bonded together with an adhesive to form an integrally structured substrate 7, and the substrate 7 thus constructed is subjected to the same process as described above. The electronic component 1 is mounted on the flexible substrate 71 using the holder 4 and the conductive rubber tube.
It is connected by crimp on the top.

This has the advantage that electronic components can be reliably and easily attached to a flexible substrate that is sensitive to heat.

Note that in the above explanation, a light emitting diode was explained as an example of an electronic component, but even for various electronic components having other electrical connection terminals, the structure of the part where the electronic component is attached to the holder 4 may be changed. By doing so, it becomes possible to connect electrically in the same way without soldering.

As described above, according to this invention, electronic components can be easily mounted, the electronic components can be easily converted into light, and compared to the connection method using soldering, there is no effect from the heat of the electronic components, and the soldering Effects such as being able to easily connect to flexible substrates that cannot be attached are produced.

In addition, when attaching electronic components as in this invention, there is no need to form an auxiliary soldering layer such as solder plating or gold plating on at least the part of the printed wiring board where the electronic components are attached, making it easier and easier to manufacture the board. It can be done inexpensively, and the printed wiring itself can be made of aluminum or the like, which has the effect of reducing the cost of the board.
