Description

[Detailed Description of the Invention] The present invention relates to an antenna terminal plate for a television receiver.

Generally, this type of antenna terminal plate is inserted through a plastic plate 1 as shown in Figure 1.
A coaxial terminal 2 for VHF signals and a flat terminal 3 for UHF signals are fixed, and this plate 1 is attached to the side wall of the TV case, and the front side of these terminals is used as an antenna, and the back side is used as a tuner. Connected.

Of these terminals, the coaxial terminal 2 is connected to the tuner by a coaxial cable 4, and the hand-shaped terminal 3 is connected to the tuner by an antenna fader wire 5.

In the case of such a conventional antenna terminal board, the center conductor 6 of the coaxial cable 4, the outer shell conductor 7, and the conductor 8 of the feder wire 5 are tied around the ends of the terminals and soldered in the latter half. This has the disadvantage that not only the performance is lowered, but also the signal level is easily affected by external electromagnetic fields, and the signal level is also attenuated depending on the length of the coaxial cable 4 and the fader wire 5.

The present invention has been made to eliminate the above-mentioned drawbacks, and aims to provide an antenna terminal plate that can improve workability and suppress signal attenuation and the effects of external electromagnetic fields.

Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 2 is a perspective view showing the structure of the antenna terminal plate according to the present invention, in which rod-shaped bodies 14 each having a chevron-shaped cross section are provided at the four corners of the plate body 1 having a peripheral edge 1a for attachment to a television housing. is planted perpendicularly to the plate 1. These rod-shaped bodies 14 have inner surfaces facing each other so as to sandwich the ridge of the tuner 20 shown in FIG. 3, and are arranged at intervals corresponding to the height and width of the tuner 20.
That is, the tuner 20 is placed at the position indicated by the dashed line.
It is arranged so that it can be attached.

On the other hand, when it is attached to one side of the tuner 20, that is, at the position indicated by the dashed line, two rod-shaped terminals 21 for UHF signals are located at the top of the side facing the plate 1, and two rod-shaped terminals 21 for VHF signals are located at the bottom of the side facing the plate 1. The coaxial terminals 22 for each are attached in a protruding state.

Further, the plate body 1 includes a plate-shaped terminal 12 having a hole 12a that fits with the rod-shaped terminal 21 of the tuner 20, and a coaxial terminal 13 having an end shape that fits with the coaxial terminal 22 of the tuner 20. It is attached at a position corresponding to the terminals 21 and 22 of 20.

Here, as shown in FIGS. 4a and 4b, the coaxial terminal 13 has one end 13a screwed to the plug connected to the antenna coaxial cord, and the other end 13b inserted and connected to the coaxial terminal 22 of the tuner. In particular, the outer shell conductor at the other end 13b is provided with a groove 13c to facilitate good contact and insertion/removal.

On the other hand, as shown in FIGS. 5a and 5b, the plate-shaped terminal 12 has a strip plate bent into a U-shape, and has a central part that maintains good contact with the rod-shaped terminal 21 of the tuner, and also allows its insertion and removal. In order to facilitate this, a round hole 12a having a groove in the radial direction is bored, and one end portion 12b of the strip plate is provided with a female screw 12c to be coupled to the feeder wire tightening terminal 11 passing through the plate body 1. There is.

If the tuner 20 is inserted between the rod-shaped bodies using the rod-shaped body 14 as a guide, the terminal 12 of the plate 1 and the terminal 21 of the tuner 20 are connected, and at the same time, the coaxial terminal 13 of the plate 1 and the tuner 20 are connected. The tuner 20 is held by the rod-shaped body 14.

By adopting this configuration, the antenna terminal board and the tuner can be joined with a single touch, making the connection extremely easy and, compared to connecting the two with a cable or fader,
The attenuation of the signal level can be kept low, and the influence of external electromagnetic fields is also reduced.

In the above embodiment, a band plate bent into a U-shape was used as the JHF signal terminal, but instead of this, for example, as shown in FIG. 15a, the whole is bent into a U-shape, and a female screw 15c is provided in the center of the terminal 15.

Further, in the above embodiment, the case where the rod-shaped terminal 21 of the tuner 20 is used for UHF signals and the coaxial terminal 22 is used for VHF signals is explained, but depending on the shape of the terminal used in the tuner 20, male and female If the related terminals are attached to the plate 1, the two can be joined with one touch in exactly the same manner as described above.

Furthermore, in the above embodiment, a chevron was used as the rod-shaped body 14, and the ridge of the tuner was held by this chevron-shaped body, but the rod-shaped body 14 may be a square rod, a round rod, or a rod having an irregular cross section. Furthermore, the position where the tuner is supported is not limited to the ridge part, but the tuner and the terminal board can be connected in the same manner as described above at other positions.

As is clear from the above explanation, according to the antenna terminal board of the present invention, connection with the tuner is extremely simplified, workability is significantly improved, and signal attenuation and the influence of external electromagnetic fields are reduced. An excellent effect can be obtained in that it can be kept sufficiently low.
