The LED unit is formed, and a coil is inserted into the LED unit and screwed and fixed to the tip of the antenna.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to an LED mounting structure for a transmitting / receiving antenna of a mobile phone or the like.

[0002]

[Prior art]

In some mobile phones and the like, a LED (light emitting diode) is attached to the tip of the antenna in order to notify the transmission / reception state by light. In this LED mounting structure, as shown in FIG. 6, for example, a diode b is soldered to a terminal of LEDa c ₁ , a capacitor d is soldered to one diode c _2, and the capacitor d and the other diode are connected. And ₃ are soldered to the terminals on the antenna body e side, respectively, and a cylindrical cap f is covered on the LEDa. When the lower end of the cap f is screwed to the tip of the antenna body e, An adhesive g is injected into the cap to fix the LED a, the diode b and the capacitor d in the cap f.

[Problems to be solved by the device]

 According to the conventional LED mounting structure, each component is connected by soldering, and there are 6 soldering points, which not only lowers the assembly work efficiency, but also causes the soldering to come off during assembly. There were problems such as defective products.

The present invention has been made in order to solve such a conventional problem, and the connection of each component can be easily attached without soldering, so that the assembling work efficiency can be improved and the soldering work can be improved. It is an object of the present invention to provide an LED mounting structure for a transmitting / receiving antenna, which can prevent the generation of defective products due to the above.

[0005]

[Means for Solving the Problems]

 As a means for technically solving the above-mentioned problems, the present invention mounts a LED and a diode on a printed circuit board to form an LED / ASSY, and fits a conductive ring on the LED to form a cylindrical shape. The gist of this method is to mount the LED unit in the cap and press-fit the lid to form a LED unit, insert a coil into this LED unit, and screw it into the tip of the antenna.

[0006]

[Embodiment of device]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In FIG. 1, reference numeral 1 is an LED unit, and as shown in FIG. 2, an LED / ASSY 2, a conductive ring 3 fitted to the LED, a cylindrical cap 4 incorporating them, and a cap 4 are provided. The lid 5 is press-fitted from the bottom to fix the LED / ASSY 2.

The LED / ASSY 2 is formed by mounting the LED 7 and the diode 8 on the wiring patterns 6 a and 6 b of the printed circuit board 6 as shown in FIG. The conductive ring 3 is made of brass or copper, and the lid 5 is made of synthetic resin or metal.

The cap 4 is formed of a synthetic resin or the like, a hole 4a for projecting the tip of the diode 7 is formed at the tip thereof, and a female screw 4b is formed on the inner peripheral surface of the bottom. There is.

The LED unit 1 can be easily attached to the tip portion 10a of the antenna 10 via the spring-shaped coil 9 shown in FIG. That is, as shown in FIG. 5, the coil 9 may be inserted into the bottom portion of the cap 4, and the female screw 4b of the cap 4 may be screwed and fixed to the male screw 10b formed on the outer peripheral surface of the tip portion 10a of the antenna 10. .

In the antenna 10 having the LED 7 attached to the tip 10a in this manner, the radio wave to be transmitted is converted into a current by the coil 9 and then guided by the diode 8 of the LED / ASSY2 to cause the LED 7 to emit light. Since the conductive ring 3 is disposed above the coil 9 as described above, a larger amount of current is generated, so to speak the function of a capacitor, and the circuit can be tuned. Therefore, not only is a capacitor unnecessary, but there is also no need to directly wire-connect (solder) the antenna 10 and the diode 8.

In this case, circuit tuning is performed through the spring-shaped coil 9 and the conductive ring 3, and the LED unit 1 can be easily attached to the tip portion 10 a of the antenna 10 without wiring the LED unit 1 and the antenna 10. It can be attached to and emit light.

[0012]

[Effect of device]

 As described above, according to the present invention, the LED / ASSY is incorporated into the inside of the cap by using the conductive ring and the lid to be integrated as an LED unit, and the coil is inserted into the LED unit so that the LED tip and the LED The LED unit can be easily attached to the tip of the antenna simply by arranging the coil between the lower part of ASSY (the side with the lid), so the connection by soldering each component is not necessary. Further, the assembly work efficiency is remarkably improved, and the excellent effect of preventing the generation of defective products due to solder is exhibited.
