DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a vehicle glass such as an automobile or a window glass for a building, which is provided with a plurality of antennas connected to two power supply portions or a plurality of heating wires for fogging prevention. Male terminals are soldered to the first power supply unit and the second power supply unit provided as above, and the internal terminal and the external conductor of the coaxial cable are connected, or the female terminal is connected to two lead wires. The present invention relates to a method of soldering a male terminal in a connection structure in which a male terminal is fitted to a male terminal and a female metal fitting used at that time.

[0002]

2. Description of the Related Art Conventionally, a glass antenna for a vehicle is connected by connecting a grounding of an external conductor of a coaxial cable to a vehicle body near the power feeding portion because a single feeding portion is provided. Vinyl without connecting the conductor directly
This was done via a lead wire such as a wire, but in recent years, a non-grounding type antenna which has a plurality of antennas and feeds power from two feeders has been proposed. For example, Japanese Patent Application No. 3-19480, Japanese Patent Application No. 3-39447, and Japanese Patent Application No. 3
No. -50026 and Japanese Utility Model Application No. 4-40360.

[0003] However, in each case, two terminals are soldered to a power supply portion formed on a sheet glass, so that it is necessary to perform positioning, and connection work may be complicated, and a coaxial cable or a lead wire may be required. When soldering the attached terminal, the jacket of the coaxial cable or the like may be damaged by the influence of heat.

[0004] The present invention has been made in view of the above points, and an object of the present invention is to provide a method of soldering a male terminal that can accurately and easily solder a positional relationship between two male terminals. With the goal.

[0005]

Means for Solving the Problems A plurality of antennas connected to two power supply portions or a heating wire for anti-fog close to the two power supply portions are provided on the rear window glass for a vehicle. In a method of soldering a first and a second male terminal to a power supply unit and a second power supply unit, respectively, the first and second male terminals are housed and connected to an inner conductor and an outer conductor of a coaxial cable, respectively, or a lead wire. And soldering the first and second male terminals to another female metal fitting having substantially the same fitting part as the fitting part of the two female terminals connected to the first and second male terminals. It is more preferable that the first and second male terminals have the same shape. However, when the first and second male terminals are soldered to the power supply portion of the heating wire, the first and second male terminals are In some cases, it is better to make the terminal portion a different shape.

The female metal fitting used at the time of soldering has three fitting surfaces formed of a bottom surface and small walls formed on both sides thereof, and the other surface has a spring piece pressed against the opposite bottom surface by a spring force. It is preferable to have a structure that includes.

[0007]

According to the present invention, a fitting portion substantially the same as the fitting portion of the first and second female terminals housed in the housing and connected to the inner conductor and the outer conductor of the coaxial cable or to the two leads, respectively. Since the first and second male terminals are soldered to another female metal fitting having the same, the positional relationship between the first and second male terminals does not shift, Positioning can be performed accurately, and since two male terminals are simultaneously held in this state, soldering can be easily performed.

In other words, the soldering can be performed simultaneously or successively while pressing the two male terminals against the power supply portion by the gripped metal fittings, either manually or when automatically soldering by a robot or the like. Compared with the conventional method of holding and soldering one terminal and then soldering while bringing another terminal to a predetermined place and holding it, the soldering can be performed in a short time and easily.

When the first and second male terminals are formed in the same shape, not only the number of parts is reduced by half, but since all the terminals are the same, there is no possibility of mistakes, and the operation is simplified. However, when soldering to the feeding part of the anti-fog heating wire, if the power supply side and the ground side are mistaken, the receiving performance of the antenna provided near the upper or lower margin of the anti-fog heating wire will be reduced. In some cases, the structure of the terminal may be different so as not to make a mistake, as shown in the second embodiment.

[0010] Further, when soldering to the power supply portion, the coaxial cable or lead wire is used without soldering, and then the female terminal is fitted. Therefore, the coaxial cable is not affected by heat and the connection work is easy. Can be.

In the female metal fitting used for soldering, three surfaces of the fitting portion are constituted by a bottom surface and small walls formed on both sides thereof, and the other surface is provided with a spring piece pressed against the opposed bottom surface by a spring force. It is preferable to provide a structure having such a structure, since it can be easily attached to and detached from the male terminal.
