As shown in FIG. 5, the antenna wire 25 from the antenna 12 is connected to the first input terminal 13 of this signal connector 11, and one end of the cable 26 is connected to the second output signal terminal 18. Connected. The other end of the cable 26 is connected to an input signal terminal (corresponding to the input signal terminal 9 in FIG. 1) provided on the antenna terminal plate of the television receiver 17.

In order to prevent the signal connector 11 from coming off due to, for example, force from the antenna wire 25 while the signal connector 11 is attached to the antenna terminal plate 21, it is preferable to connect the signal connector 11 to the antenna terminal plate 21 as shown in FIG. A fixing screw 27 may be provided on the signal connector 11 side, and a screw hole 28 to be screwed therewith may be provided on the antenna terminal plate 21 side.

Next, the usage and operation of this signal connector 11 will be explained.

First, when taking the VTR 14 outdoors, for example,
The signal connector 11 is the antenna terminal plate 2 of the VTR 14
Will be removed from 1. However, antenna wire 2
5 and cable 26 are still connected to signal connector 11
is connected to. In this state, the control input terminal 20 of the signal connector 11 and the control output terminal 24 of the VTR 14 are not connected, so the switch section 19 of the signal connector 11 is placed in the position indicated by the broken line in the connection diagram of FIG. Yes, first input signal terminal 13
and the second output signal terminal 18 are in a connected state. Therefore, the signal from antenna 12 is
The signal is directly supplied from the first input signal terminal 13 to the television receiver 17 via the second output signal terminal 18, so that only the television receiver 17 can receive the signal.

Next, when using the VTR 14 indoors, the signal connector 11 connects to the antenna terminal plate 2 of the VTR 14.
1. In this state, the signal connector 11
Since the control input terminal 20 of the VTR 14 is connected to the control output terminal 24 of the VTR 14, the switch section 19 of the signal connector 11 can be driven by a control signal from the VTR 14. Therefore, the switch section 19
is driven by the control signal, the switch section 19
is the position indicated by the solid line in the connection diagram of FIG. 2, and the antenna signal is supplied to the input signal terminal 23 of the VTR 14 via the first input signal terminal and the first output signal terminal 16, The signal from the output signal terminal 22 of is supplied to the television receiver 17 via the second input signal terminal 15 and the second output signal terminal 18 and the cable 26. In this way, it becomes possible to use the VTR 14 and television receiver 17 as a system.

Furthermore, when the switch section 19 is not driven by a control signal with the signal connector 11 attached to the antenna terminal plate 21 of the VTR 14, the switch section 19 is located at the position indicated by the broken line in the wiring diagram of FIG. , only the television receiver 17 can perform reception.

As described above, the control signal can easily switch between a state where the VTR 14 and the television receiver 17 can be used as a system and a state where only the television receiver 17 can receive data.

In addition, in the above embodiment, the signal connector 11 is
It had a detachable structure that could be attached to or detached from the antenna terminal plate 21 of the VTR 14. Therefore, it has the advantage that the signal connector 11 and the VTR 14 can be easily connected and separated. However, if such advantages are not desired, a structure in which the signal connector and the VTR are connected by cable may be used instead of the structure of the above embodiment.
That is, if explained in relation to the above embodiment, the second input signal terminal 15, the output signal terminal 22, the first
The output signal terminal 16 and the input signal terminal 23 and the control input terminal 20 and the control output terminal 24 are each connected by cable. moreover,
As described above, the control input terminal 20 and the control output terminal 24 may be directly connected without cable connection between all terminals, for example, without cable connection.

Further, in the above embodiment, the signal connector was applied to one antenna input signal (for example, VHF input signal), but when it is shared with another antenna input signal (for example, UHF input signal) The signal connector of this invention can also be applied to. Regarding this, Figures 6 and 7
This will be explained with reference to the figures.

Referring to FIGS. 6 and 7, a received signal from a VHF antenna is input to the first input signal terminal 13. Further, the second output signal terminal 18 outputs a signal to the VHF input terminal of the television receiver. This embodiment is configured to distribute UHF antenna signals to a VTR and a television receiver. That is, the signal connector 11a includes an input signal terminal 29 that inputs a signal from a UHF antenna, an output signal terminal 30 that outputs a UHF signal to the UHF input signal terminal of the VTR,
It also has an output signal terminal 31 that outputs a signal to the UHF input terminal of the television receiver, and the signal from the UHF antenna is distributed to each output signal terminal 30 and 31 by a distributor 32. has been done. Although not shown, in this embodiment, the VTR only needs to be provided with a terminal that fits into the output signal terminal 30 when the signal connector 11a is attached to the VTR.

[Effects of the invention] As described above, if the removable signal connector according to this invention is inserted between the antenna wire and the video player and connected in advance, the video player and the video recording/playback device can be connected. Since it is extremely easy to combine and separate the elements, the effect will be great if it is applied to, for example, a stationary and portable type VTR.
Furthermore, if you install as many signal connectors according to this invention as there are video playback devices, you can easily connect any video playback device with one video recording and playback device. VTR in the room
can be easily moved.
