Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for connecting a so-called built-in antenna to an internal circuit installed in a television receiver.
This makes it possible to easily connect the antenna and the antenna terminal via a lead wire.

In a television receiver, as shown in FIG. 1, an antenna 2 is fixed to a rear cabinet (back cover) 1, and an antenna terminal attachment part 3 is installed, and the antenna 2 is connected to this antenna terminal attachment part 3. Alternatively, a lead wire from an external antenna (not shown) can be connected. At this time, the lead wire connecting between the antenna 2 and the antenna terminal area part 3 should be connected to the antenna terminal plate that constitutes the antenna terminal mounting part 3 in order to prevent the terminal part from entering the set. A hole with a diameter large enough to accommodate the wire is provided, a lead wire is inserted into the set from outside the set, and one end of the lead wire is connected to the antenna by soldering.

, FIG. 2, and FIG. 3 show the above-mentioned conventional means,
4 is the antenna terminal plate described above, 6 is a lead wire whose one end is connected to the antenna 2, and the hole 6 provided in the antenna terminal plate 4 is
The fork terminal 7 is inserted into the inside of the set, and the fork terminal 7 is connected to one end which is exposed outside the set by caulking. 8
, 8 is an antenna terminal attached to the antenna terminal plate 4, which integrally has projecting pieces 8a, 8a that protrude into the inside of the set.
It is connected to an internal circuit via a connector 9 inserted and connected to the projecting pieces 8a, 8a. Then, connect the other end of an external antenna lead wire (not shown) whose one end is connected to the external antenna or the fork terminal 7 of the lead wire 6 to the antenna terminals 8, 8 to connect the built-in antenna 2 or the external antenna. In Fig. 3, 10.10 is a hole for attaching the antenna terminals 8, 8 to the antenna terminal plate 4.
8 are attached to the antenna terminal plate 4 by a pair of elastic locking pieces, each sandwiching the antenna terminal plate.

However, with this method, in order to prevent the fork terminal 7 at one end of the lead wire 6 from entering inside the center,
The other end of the lead wire 6 is inserted inward through the hole r, which has approximately the same diameter as the lead wire 6, and the other end of the lead wire 5 is soldered to the antenna 2, which is already fixed to the rear cabinet. It was time-consuming and had poor workability.

In view of the above points, the present invention is designed to first perform the lead wire preparation work so that the lead wires can be attached at the same time as the antenna and antenna terminal are attached. An example of this will be described below with reference to FIGS. 4 to 7. Components in the drawings that are the same as those in FIGS. 1 to 3 will be described with the same reference numerals.

In the figure, fork terminals 7.7 are connected to both ends of the lead wire 6, for example, by caulking. On the other hand, in the antenna terminal plate 4, the antenna terminal mounting hole 1
0.10, and a holding hole 11 for the lead wire 6 is provided continuously to one mounting hole 1o. As shown in detail in FIG. 6, the diameter of the holding hole 11 at the end connected to the mounting hole 10 is larger than the diameter of the lead wire 6, and the diameter decreases as the distance from the mounting hole 1o increases. It consists of a hole 11a and a circular hole 11b connected to an end portion of the elongated hole 11a having a diameter smaller than the diameter of the lead wire 6. The diameter of this circular hole 11b is made slightly larger than the diameter of the lead wire 6.

When wiring the lead wire 6 in the above configuration, the seventh
As shown in the figure, the fork terminal 7 at one end of the lead wire 6 is connected to the antenna 2 at the same time as the antenna 2 is fixed with a screw 12 for fixing the antenna 2 to the rear cabinet 1. Then, pull out the other end of the lead wire 6 from the mounting hole 1o, which has a much larger diameter than the fork terminal 7, and then pull out the other end of the lead wire 6.
is moved inside the elongated hole 11a and positioned in the circular hole 11b.

Thereafter, the antenna terminal 8.8 is attached to the antenna terminal plate 4 using the attachment hole 1o. This state is shown in Figures 6 and 7.
As shown in the figure. In this state, the diameter of the end of the elongated hole 11a that is continuous with the circular hole 11b is smaller than the diameter of the lead wire 6 (of course, the diameter of the hole 11b is smaller than the diameter of the fork terminal 7).
, the fork terminal 7 does not pass through the hole 11 into the inside of the set. Furthermore, since the fork terminals 7.7 can be connected to both ends of the lead wire 6 as described above, the lead wire 6 can be connected to the antenna 2 at the same time as the antenna 2 is being fixed. Furthermore, the lead wire 6 can be pulled out through the mounting hole 1o, which has a diameter much larger than the diameter of the fork terminal 7, and the circular hole 11b.
Since it can be moved smoothly, the work efficiency is improved compared to the conventional method, and the overall work time can be significantly reduced.

In FIG. 7, reference numeral 12 denotes a rib for holding the lead wire in the rear cabinet 2, and the lead wire 6 is held by press-fitting it into the central groove.

As explained above, according to the present invention, by providing a hole for holding a lead continuously with a hole for attaching an antenna terminal,
Connection terminals can be connected to both ends of the lead wire,
Furthermore, this greatly reduces the working time required to connect the built-in antenna, which is extremely advantageous in practice.
