Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feeder line connector device for a glass antenna used for radio wave reception.

[0002]

2. Description of the Related Art As a conventional feeder line connector device for a glass antenna, the one shown in FIG. 2 has been reported by Japanese Utility Model Application Laid-Open No. 2-36204 filed by the present applicant.

In FIG. 2, 10 is a feeding point of a glass antenna, 11 is a window glass plate, 18 is a male terminal portion, 19 is a female terminal portion, 20 is a male contact, 23 is a female terminal case, and 27 is the periphery of the antenna. Circuit board with circuit, 2
8 feeder wires soldered to female contacts, 2
9 is a female contact.

[0004]

When the male terminal portion 18 is soldered to the feeding point 10 on the window glass plate 11, the circuit board 27 housed in the male terminal portion 18 is also heated by heat conduction, so that the circuit board is heated. The temperature of the circuit element of the antenna peripheral circuit provided in No. 27 also rises, which is a factor that deteriorates reliability.

Further, when the circuit board 27 fails, it is necessary to remove the case 23 by overheating the case 23, and re-solder to attach a good circuit board 27, which requires many replacement steps, resulting in poor productivity. . Further, due to such replacement, the heat history is applied twice more to the window glass plate 11, which causes the deterioration of the strength of the window glass plate 11 and the feeding point 10.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and female terminals are provided on a case, a circuit board accommodated in the case, and side portions of the case. The circuit board is provided with an antenna peripheral circuit, and the circuit board is connected with a feeder wire for sending a reception signal of the glass antenna to the receiver side. By having a male contact, and by fitting the female contact and the male contact, the female terminal portion and the male terminal portion are connected,
A feeder line connector device for a glass antenna, characterized in that a received signal of a male terminal portion is sent to a receiver side via a female terminal portion, and is composed of a female terminal portion and a male terminal portion.

[0007]

In the present invention, since the circuit board is on the feeder line side, even if the window glass plate side is overheated, heat does not reach the circuit board, so there is no failure of the circuit board due to heat. In addition, it is easy to replace the circuit board when it fails.

Embodiments will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view of an embodiment, in which 1 is a female terminal portion, 2 is a feeder line soldered to a circuit board, and 3 is a feeder line.
Female terminal case, 4 molded resin, 5 circuit board, 6 female contact, 7 male terminal, 8 male female contact, 9 male terminal 7 leg portion, 10 glass antenna , 11 is a window glass plate.

As shown in FIG. 1, the female terminal portion 1 comprises a case 3, a circuit board 5 housed in the case 3, and a female contact 6 provided on a side portion of the case 3, and the circuit board 5 is made of glass. A feeder line 2 for sending a reception signal of the antenna to the receiver side is connected.

The feeder line 2 is connected to the circuit board 5 by connecting means such as soldering. The circuit provided on the circuit board 5 is an antenna peripheral circuit. Here, the antenna peripheral circuit is a matching circuit, a preamplifier, a resonance circuit, or the like that performs impedance matching between the glass antenna and the input impedance of the receiver or the like in the next stage, and is not particularly limited.

Further, as shown in FIG. 1, the male terminal portion 7 is formed.
Has a leg portion 9 and a male contact 8, and by fitting the female contact 6 and the male contact 8 to each other, the female terminal portion 1 and the male terminal portion 7 are connected, and the received signal of the male terminal portion 7 is a female terminal. It is sent to the receiver side via the unit 1.

In the embodiment, the male contact 8 is adopted as the contact on the side of the window glass plate 11, and the feeder wire 2 is used.
Although the female contact 6 is adopted as the side contact, the female contact may be adopted as the window glass plate 11 side contact and the female contact may be adopted as the feeder line 2 side contact. In this case, the circuit board 5
Is stored in the terminal portion on the feeder line 2 side as in FIG.

Further, the shape of the case 3 is not particularly limited to the shape shown in FIG. 1, and the height may be higher than that in FIG.

The feeder line connector device according to the embodiment is manufactured as follows. The feeder line 2 is subjected to terminal processing so as to function as a relay line with an appropriate length. Next, the peripheral circuit is mounted on the circuit board 5. The feeder wire 2 is soldered to the circuit board 5. Both may be soldered together by a wave soldering method or the like.

Next, the circuit board 5 is housed in the case 3, and the circuit board 5 is connected to the case 3 by means such as soldering at a fitting portion of the circuit board 5 provided in the case 3. Next, the circuit board 5 is filled with resin and cured.

[0017]

According to the present invention, since the circuit board is on the feeder line side, even if the window glass plate side is overheated, the heat does not reach the circuit board, so there is no failure of the circuit board due to heat. Further, there is an excellent effect that the circuit board can be easily replaced when it fails.
