Description

Signal Delivery System of Camcorder {Signal delivery system in camcoder}

The present invention is to install a camcorder to supply power to the camcorder while receiving video and audio signals from the camcorder and to transfer video and audio signals from the outside to the camcorder. When connecting and disconnecting the camcorder, the connection terminal is protected by recessing the signal transmission terminal.

Because of the small size of the camcorder, the situation where the power supply jack, the video input / output jack and the voice input / output jack are placed on the outside of the camcorder is subject to a lot of space constraints. to be.

The signal input / output jack of the camcorder is freely used to move the camcorder freely, and is mostly used when shooting in a fixed state at a fixed position or editing film.

A device for solving this problem is disclosed in Japanese Patent Laid-Open No. 5-56318, which makes it easy to connect and regenerate a connection with another electric machine when the camera-integrated VTR is set in a connection device. The inconvenience of having to provide a separate connection device and adapter.

The present invention does not install the signal input / output jacks required by the camcorder directly on the camcorder, but rather by installing them on a separate power supply. When connecting the camcorder to the power supply, the connectors of the signal input / output jacks are connected to each other. Without the difficulty of installing the signal input and output jacks, only the signal input and output terminals are installed to supply power to the camcorder and to input and output video and audio signals.

The present invention is provided with a power supply jack and a signal input and output jack on the side and having a coupling structure for attaching and detaching the camcorder on the upper side and having a power supply with a terminal connection device on one side of the coupling structure and connecting the terminal to the bottom of the camcorder detachable from the coupling structure. It is made by providing a signal input and output terminal coupled to the device and the input and output of the power and video and audio signals between the jack and the camcorder through the connection device and the signal input and output terminals.

Here, the connecting device allows the built-in terminal to protrude according to the mounting of the camcorder, and the protruding terminal is automatically connected to the signal input / output terminal of the camcorder, thereby providing power without installing a separate power jack and signal input / output jack between the power supply and the camcorder. Input and output of video and audio signals.

1 is a perspective view of the power supply of the present invention,

The power supply 1 has a power jack 2 into which a power cord is inserted, and a signal input / output jack 3 capable of transmitting and receiving video and audio signals to and from an external video reproducing apparatus. Coupling structure (4) is formed to be fitted, it is made by providing a signal transmission connecting device (5) on one side of the coupling structure (4).

Here, the coupling structure 4 forms the projection jaw 6 at a predetermined height from the bottom and then mounts the camcorder to the power supply 1 by fitting the lower portion of the camcorder in the space between the bottom and the projection jaw 6.

In other words, if the camcorder is pushed in the direction of the arrow while keeping the camcorder in close contact with the floor, the camcorder is mounted in the coupling structure (4). At this time, the signal input / output jack and the power jack are not separately installed in the camcorder. It is made based on the power jack 2 and the signal input / output jack 3.

The signal applied to the power jack 2 and the signal input / output jack 3 is transmitted to the connecting device 5 and transmitted to the camcorder through the signal input / output terminal connected to the connecting device 5, and the output signal of the camcorder is also connected to the connecting device 5. Is output to the signal input / output jack (3).

Figure 2 is an exploded perspective view of the connection device of the present invention,

The connecting device 5 includes a support plate 10 fixed to the power supply 1, a terminal 12 fitted to the connection holder 11 inside the support plate 10 and having elasticity, and one side of the terminal 12. A spring 17 fitted into the groove 14 and having a slide protrusion 13 formed thereon and a fixing protrusion 16 formed on one side of the slide holder 13 to support the slide holder 13. And a cover 19 covering the support plate 10 and forming a groove 18 through which the terminal 12 may protrude.

Here, the connection holder 11 is electrically coupled to the signal input / output jack 3 and the power supply jack 2 so that a power supply or an input / output signal is supplied to the terminal 12 inserted into the connection holder 11.

The slide holder 13 in which the terminal 12 is fitted into the groove 14 has a pusher protrusion 15 when the pusher protrusion 15 protrudes out of the cover 19 to push the camcorder into the coupling structure 4. Will push.

The side surface of the slide holder 13 is installed by the spring 17 is supported, the slider holder 13 is always subjected to elastic force by the elasticity of the spring (17).

In the upper portion of the cover 19, when the slide holder 13 is pushed, a groove 18 protruding from the tip of the terminal 12 is formed to connect the terminal 12 protruding into the groove 18 and the signal input / output terminals formed on the camcorder. To be.

The operation of the connection device 5 will be described in detail with reference to the drawings of FIGS. 3 to 5.

When the camcorder is pushed into the coupling structure 4, the camcorder is mounted, and the pusher 15 of the connecting device 5 is pushed so that the slide holder 13 is pushed to the state shown in FIG. Is done.

When the slide holder 13 is pushed, the elastic terminal 12 protrudes into the groove 14 and protrudes into the groove 18 of the cover 19 which is drilled at the same position.

At this time, the spring 17 is left in a compressed state when the camcorder is mounted.

When the terminal 12 protrudes into the grooves 14 and 18, the terminal 12 is connected to the signal input / output terminal 20 of the camcorder. From this time, the camcorder is supplied with power through the power supply jack 2 and through the signal input / output jack 3. Input and output video or audio signals.

In this way, when the camcorder is mounted on the power supply 1, the terminal 12 of the connecting device 5 automatically protrudes and is connected to the signal input / output terminal 20 of the camcorder so that the signal input / output and the power supply are supplied through the power supply 1. Is done.

This allows you to edit at home without having to install a jack on your camcorder.

If you do not use the camcorder or want to take it with you, you must disconnect the camcorder from the power supply (1).

When the camcorder is pushed in a position opposite to the direction of the arrow in Fig. 1 in the coupling structure 4, the camcorder is separated. At this time, the force for pushing the pushing protrusion 15 of the slide holder 13 is released, so that the slide holder 13 is a spring ( When the slide holder 13 is pushed, the terminal 12 is embedded into the groove 18 as shown in FIG. 5 when the slide holder 13 is pushed.

Therefore, when the camcorder is disconnected from the power supply 1, the terminal 12 does not protrude and is recessed inside the connecting device 5, thereby preventing damage to the terminal 12.

The present invention can receive power and signal transmission through the power supply without installing the power jack and signal connection jack directly on the camcorder, so that the jack installation of the camcorder can be eliminated. It protrudes and connects with the signal input / output terminal of the camcorder to prevent terminal damage of the connecting device.
