Description

[Detailed Description of the Invention] The present invention relates to an improvement of an antenna terminal device for a UHF tuner, and an object thereof is to provide an antenna terminal device that is easy to assemble and has high reliability.

Hereinafter, details of the present invention will be explained according to an embodiment shown in FIGS. 1 to 3.

In the figure, 1 is a terminal plate made of insulating synthetic resin, 2 and 3 are hollow antenna terminal pins embedded in the terminal plate 1, and both ends of the antenna coil 4 and the antenna resistance are connected from the bottom surface of the terminal plate 1. By inserting one lead wire 6 of 5, the coil 4
Furthermore, the ends of the resistor 5 are soldered to the tips of the antenna terminal pins 2 and 3.

7 is the collar of the terminal board 1, and the terminal board 1 is attached to the chassis 8.
It functions as a member to prevent it from coming off and to regulate its position when inserted. 9, 9 are notches provided on both sides of the terminal plate 1, and holder 1, which will be described later.
It is adapted to fit with the protrusions 11, 11 of 0.

Reference numeral 10 denotes a holder made of insulating synthetic resin, which is separated by a partition wall 12 into a bottomed storage chamber 13 for storing the antenna coil 4 and a partially bottomed storage chamber for storing the antenna resistor 5. It is divided into a chamber 14. Then, one of the storage chambers 13
is formed to have a size approximately equal to the external shape and dimensions of the loop portion 15 of the antenna coil 4, and prevents vibration and deformation of the antenna coil 4, and also prevents vibration and deformation of the antenna coil 4 when connecting the antenna coil 4 and the antenna terminal pins 2 and 3. It is also now possible to regulate the location of or,
The other storage chamber 14 has a bottom portion sufficient to prevent the antenna resistor 5 from falling out, and a hole 1 sufficient to insert the lead wire.
6. 11, 11 are elastic projections formed integrally with the holder 10, which are inserted and fitted into the notches 9, 9 of the terminal board 1, respectively;
The terminal plate 1 and the holder 10 are assembled together.

Further, the joint surface (contact surface) between the terminal plate 1 and the holder 10 is formed into a step-like step (see FIG. 2), so as to ensure the alignment and combined state of both the terminal board 1 and the holder 10. It's getting old.

When assembling, the storage chamber 13 of the holder 10
Insert the loop portion 15 of the antenna coil 4 to the bottom, and insert the antenna resistor 5 into the other storage chamber 14 so that the lead wire 17 at one end of the antenna resistor 5 is led out from the hole 16, and then, While inserting both ends of the antenna coil 4 into the antenna terminal pins 2 and 3 and the other lead wire 6 of the antenna resistor 5 into the antenna terminal pin 2, insert the protrusion 11 of the holder 10,
11 into the notches 9, 9 of the terminal plate 1, the terminal plate 1 and the holder 10 are integrated as described above, and the coil 4 and the resistor are connected at the tips of the antenna terminal pins 2, 3. 5 and pins 2 and 3 are connected by soldering. By doing this, the insertion position of the antenna coil 4 is always regulated to the desired position, thus facilitating the connection work between the coil 4 and the pins 2 and 3, and
As shown in FIGS. 2 and 3, the loop portion 15 of the antenna coil 4 is almost immovable in the storage chamber 13, so if a coil 4 that has been formed and adjusted in advance is used, its deformation and vibrations can be prevented. (i.e., although not shown,
In the conventional device of this type, the storage chamber 13 is unnecessarily large compared to the antenna coil 4, and the degree of insertion of the coil 4 into the storage chamber 13, in other words, the connection work between the coil 4 and the antenna terminal pins 2 and 3 is difficult. is complicated, and
The antenna coil 4 tends to vibrate due to vibrations, etc.
Therefore, the degree of coupling varied, resulting in low reliability. ).

Then, the terminal plate 1 and the holder 10 assembled as one unit as described above are inserted into the hole of the chassis 8 and fixed by an appropriate means such as a screw, and the lead of the antenna resistor 5 led out from the holder 10. The assembly is completed by soldering the wire 17 to a predetermined location on the chassis 8.

As mentioned above, according to the present invention, the bottomed storage chamber 1
3, the antenna coil 4 is placed in a partially bottomed storage chamber 14.
Since the antenna resistor 5 is housed in the holder 10, the coil 4 and the resistor 5 do not fall out of the holder 10.
With the resistor 5 inserted, the fitting of the holder 10 and the terminal plate 1, as well as the insertion and connection of the antenna terminal pins 2, 3, the coil 4, and the lead portion of the resistor 5 can be simultaneously performed easily, and the workability is improved. In good condition.
Furthermore, since the loop portion 15 of the antenna coil 4 is approximately the same size as the storage chamber 13, the insertion position of the coil 4 can be regulated at the bottom of the storage chamber 13, and
After insertion, vibrations caused by shock etc. are greatly suppressed,
Moreover, it is possible to realize an antenna terminal device for a UHF tuner that has no fear of deformation and is therefore mechanically and electrically reliable, and has great practical value.
