Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a glass antenna terminal, and more particularly to connection with a glass antenna for a vehicle.

[0002]

[Prior art]

 As shown in FIG. 4, the conventional glass antenna terminal is composed of only the contact terminal 72 made of a metal material. The contact terminal 72 is formed of a standing portion 71, a contact portion 73 bent laterally on the upper end side, and a soldering portion 75 bent on the lower end side. The attachment of the contact terminal 72 to the glass surface G is performed by soldering the soldering portion 75 to the solder pad 74 of the glass antenna formed on the glass surface G.

[0003]

[Problems to be solved by the device]

 In the conventional glass antenna terminal, since the plurality of contact terminals 72 are individually soldered to the solder pads 74 of the glass antenna at the soldering portions 75, there is a problem that the number of steps is increased during mounting. Further, when the antenna is connected to an optional device (such as a car phone), the contact terminal 72 is exposed, which is dangerous.

Further, the conventional contact terminal has a high height from the contact portion 73 to the soldering portion 75 as shown in FIG. 4 and is connected by a discrete wire. However, there is a drawback that the attenuation of the electromagnetic wave energy at the terminal portion becomes large.

An object of the present invention is to solve the above problems and provide a terminal for a glass antenna having excellent safety, mountability, and high frequency characteristics.

[0006]

[Means for Solving the Problems]

 According to the present invention, a plurality of pin contacts each including a contact portion, a soldering portion attached to a soldering pad on a glass surface, and a holding portion integrally connecting the contact portion and the soldering portion, The housing is fixed to the holding portion and surrounds a side portion of the contact portion of the pin contact together with the glass surface, and the contact has a parallel step shape with the contact portion and the soldering portion. The holding portion is bent so that a gap is formed between the contact portion and the glass surface, and the housing is between the glass surface on the soldering portion side. A terminal for a glass antenna is obtained, which is characterized in that a gap is formed in it.

[0007]

[Action]

 According to the present invention, since the side surface of the pin contact is separated and surrounded by the glass surface and the housing, and there is no wall surface portion on the glass surface side of the housing, the height dimension of the housing from the glass surface can be reduced. Can be lowered.

The absence of the wall surface of the housing on the glass surface side of the housing makes it possible to shorten the distance between the contact and the glass surface. It becomes possible to add the function as a section, and it is possible to reduce the attenuation of the electromagnetic wave energy at the terminal section even when the frequency is high.

Further, since the two pin contacts are press-fitted into the housing, workability at the time of soldering the glass surface is improved.

Further, since the periphery of the contact portion of the pin contact and the portion other than the glass surface are covered with the housing, even if the terminal is not used, the contact terminal is not directly touched and it is safe.

Furthermore, the contact portion of the contact and the soldering portion are parallel stepped, and are the glass surface side end surface of the housing. Since the lower part floats above the glass surface, that is, the terminal attached to the glass surface is the glass surface (that is, the terminal is in the state where the upper end side of the housing and the soldering part of the contact are in contact with the glass surface). Even if it is twisted in the opposite direction, the lever can prevent overload on the soldered part.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

The terminal of the present invention, as shown in FIGS. 1 (a), 1 (b), and 1 (c), is composed of two pin contacts 10 and a housing 3 provided around them.

The pin contact 10 includes a contact portion 11 for contacting (connecting) a contact (see FIG. 3) of a mating connecting terminal, a soldering portion 13 for soldering and connecting to the soldering pad 5 on the glass surface G, and a contact portion. The holding portion 15 integrally connects the portion 11 and the soldering portion 13, and has a flat shape. The pin contact 10 is bent in parallel steps so that the soldering portion 13 is in close contact with the soldering pad 5 on the glass surface G and is lifted from the glass surface from the holding portion 15 to the contact portion 11. There is.

The housing 3 is held by the holding portion 15 by press-fitting the holding portion 15. The housing 3 surrounds the side of the pin contact 10 and is open on the glass surface side. That is, no wall surface is formed on the glass surface side of the housing 3.

Further, at a predetermined position of the contact portion 11 of the pin contact 10, there is formed a locking recess 12 that engages with the socket contact of the mating connection terminal.

Therefore, the housing 3 of the glass antenna terminal 1 of the present invention has no wall on the glass surface G side, and only the upper end portion of the housing 3 and the soldering portion 13 of the pin contact 10 have the glass surface G. 2), the remaining part is lifted up from the glass surface. Therefore, as shown in Fig. 2 (a), even if a twisting force (X direction) is applied to the housing 3, the soldering part 13 is not overloaded. That is, as shown in FIG. 2B, when there is no gap between the housing 3 and the glass surface, when a twisting force acts in the X direction, a reaction force (Y direction) is applied to the glass surface G and the housing 3. As a result, the soldering portion 13 of the pin contact 10 is overloaded in the direction opposite to the reaction force (Z direction), and the soldering portion 13 may peel off from the solder pad 5.

According to the present invention, since the soldering portion 13 is not overloaded as described above, the soldering portion 13 will not be peeled off even when a prying force acts on the housing 3.

Next, the case where the terminal of the present invention and the mating side connecting terminal are connected will be described.

As shown in FIGS. 3 (a), 3 (b), and 3 (c), the mating connection terminal 6 is fitted to the insulator 61 extending along the glass surface G and the contact 10 of the terminal 1 of the present invention. It has a socket contact 63 for connection. At a predetermined position of the socket contact 63, a protrusion 64 that engages with the locking recess 12 formed in the pin contact 10 is formed.

The insulator 61 of the mating side connecting terminal 6 is formed so as to enter the gap between the housing 3 and the glass surface G of the terminal 1 of the present invention. Thus, when the insulator 61 of the mating side connecting terminal 6 is inserted into the housing 3 of the terminal 1 and the glass surface G, the twisting force may act on the housing 3 when the mating side connecting terminal 6 is inserted or removed. . However, as described above, the terminal of the present invention does not overload the soldering portion 13 even when such a twisting force is exerted.

For example, the signal cable (center conductor) of the coaxial cable C is connected to one contact of the socket contact 63 of the mating side connection terminal 6, and the ground side cable (external conductor) is connected to the other contact. . The coaxial cable C is stretched along the glass surface G.

As described above, in the present embodiment, since the coaxial cable is used for the cable of the counterpart connection terminal 6, the attenuation of high frequency signals becomes smaller. Further, according to the present invention, since the distance between the pin contact 10 and the glass surface G becomes small, it becomes possible to use the pin contact 10 and the socket contact 63 connected thereto as a part of the antenna. . As a result, the distance between the antenna and the coaxial cable C becomes extremely small, and the attenuation of the electromagnetic wave energy at the terminal portion can be suppressed to a small level even in the high frequency region. In the figure, 63a is a connection portion of one socket contact 63 with the central conductor of the coaxial cable C, and 63b is a connection portion of the other socket contact 63 with the outer conductor of the coaxial cable C.

Needless to say, the cable connected to the glass antenna terminal of the present invention is not limited to the coaxial cable, and may be a flat cable. .

Further, for example, the pin contact 10 is a glass antenna terminal in which a plurality of two are mounted, that is, two for a vehicle-mounted TV and two for a vehicle telephone so that the antennas of the vehicle-mounted TV and the vehicle telephone can be simultaneously connected. You can also

[Effect of device]

 According to the present invention, since the two pin contacts are press-fitted into the housing to form the antenna terminal, the mountability of soldering can be improved. In addition, since the area around the contact portion of the pin contact is covered with the housing, accidents due to contact with the terminal inside the vehicle after mounting will not occur, which is preferable in terms of safety.

Further, according to the present invention, since the surface of the housing that faces the glass surface is in the open state, the height of protrusion from the glass surface can be reduced. Moreover, since the distance from the pin contact to the glass surface can be reduced, the pin contact can be made to function as a part of the antenna, the distance between the cable and the antenna can be reduced, and even in the high frequency range. A glass antenna terminal capable of reducing the attenuation of energy of electromagnetic waves transmitted and received through the antenna is obtained.
