Abstract

PURPOSE:To prevent an electronic device, e.g. a LED, from floating in an automatic soldering equipment by a structure wherein a spacer being fitted to a substrate is provided with a specific split and a guide part for holding the electronic device resiliently. CONSTITUTION:In an audio system, for example, a display window is formed by mounting a device 2, e.g. an LED, having multiple connecting terminals on a substrate 3 and then soldering the device 2 automatically thereto. A spacer 1 being fitted to the substrate 3 is provided with a slit 102 for receiving the terminals 201-n of the electronic device 2, and the slit 102 is provided with a part 103 for guiding insertion of the pin of a multi-pin device. Furthermore, slits 104, 105 are made on the opposite sides of the slit 102 along the row of the pins of electronic device 2 in order to hold the electronic device 2 resiliently. For example, the spacer 1 is provided with a tapered part 103 for guiding insertion of the terminals 201-n of a display LED 2 into the slit 102.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an audio device, and more particularly, to a spacer for a light emitting diode when a substrate is manufactured by an automatic soldering device, such as when displaying a display window using a multi-terminal such as a light emitting diode. Is related to the shape of.

[0002]

2. Description of the Related Art FIG. 4A is a perspective view showing a conventional example of a spacer for a light emitting diode of an audio device. In the figure, the spacer 1 ′ is arranged between the light emitting diode 2 and the display substrate 3 and is in a soldered state, and display is performed through the display window 4 by the light emission of the light emitting diode body. Further, FIG. 4 (b) is a cross-sectional view before soldering the light emitting diode and the spacer to the substrate by the automatic soldering device. The light emitting diode 2 is arranged on the upper surface of the spacer 1 ', and the light emitting diode 2 and the spacer 1'
Is placed on the substrate 3, and a total of three layers form a substrate unit. The light emitting diode 2 is composed of a main body 20 and connection terminals 201 to n having a plurality of legs, and signals from the substrate are transmitted to the main body 20 through the terminals 201 to n and emitted. A hole 30 is formed in the spacer 1'and the substrate 3 so that the terminal 2
01 to n pass through the holes of the spacer 1 and the substrate 3 and are exposed on the lower surface of the substrate. With the above-described configuration, the board unit is formed and soldered by the automatic soldering device.

[0003]

However, in the above-mentioned prior art, when the board unit is soldered by the automatic soldering apparatus, it is placed on the upper surface of the board by the hot air for adhering the solder from the lower inside of the apparatus to the lower surface of the board. Another problem is that the light emitting diode and the spacer are lifted up and soldered as it is, leaving a gap between the light emitting diode and the substrate.

[0004]

According to the present invention, the spacer 1 provided between the light emitting diode and the substrate is elastically held at the terminal of the light emitting diode by a spacer with a terminal stopper utilizing the elastic force of the molded product to float the light emitting diode. It is characterized by preventing.

[0005]

Therefore, the spacer structure between the light emitting diode and the substrate can hold the light emitting diode terminal by the elastic force of the molded component and prevent the floating of electronic components such as the light emitting diode in the automatic soldering apparatus.

[0006]

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a surface view of a spacer showing an embodiment of the present invention, FIG. 2 is a sectional view thereof, and FIG. 3 is a sectional view when it is mounted on a substrate.

The spacer 1 according to the present invention has electronic terminals, for example, connecting terminals 201 to n of a plurality of display light emitting diodes 2 inserted therein, and has a space interval t1 and a main body 2 of the light emitting diode 2.
The holding portion 101 on the surface where 0 is placed has a taper portion 103 for guiding insertion of the terminals 201 to n into the slit 102, and the slit 102 has a slit width narrower than the outer diameter of the terminals 201 to n. .

Therefore, slits 104 and 105 are provided on both sides of the slit 102, and the elastic holding portions 106 and 10 are provided.
7 is a piece of elasticity having widths t2 and t3 and has a force for holding at least 201 and 20n of the terminals 201 to n of the light emitting diode 2.

Further, the spacer 1 and the substrate 3 are inserted into the holes of the substrate 3 by the protrusions 108 and the engaging pieces 109 of the spacer and positioned at a predetermined position. At this time, via the slit 102 of the spacer, the terminals 201 to n of the light emitting diode 2 are placed at positions relative to the connection holes 301 to n of the substrate, and the terminals 201 to n of the light emitting diode 2 are placed corresponding to the holes of the distribution circuit to be connected. It In the case of automatic soldering, when a large number of connection terminals are solder-dipped into a light-weight body such as a light emitting diode, the spacer 1 receives a force in a floating direction, but the spacer 1 engages with the substrate 3 and the spacer 1
Since the elastic holding portion elastically holds the terminal of the light emitting diode, a force against the floating works and is held. Further, the positions of the terminals connected from the slits 104 and 105 can be visually confirmed, and the workability is improved when the terminals are manually inserted.

[0010]

As described above, in order to display a display window using a light emitting diode or the like in an audio device or the like, when the light emitting diode is soldered to the board by an automatic soldering device, the board and the light emitting diode are In the meantime, the spacer with the elastic stopper of the molded product can prevent the light emitting diode from floating in the automatic soldering device.
