The present invention relates to a detachable device for a TV tuner of a camcorder, and more particularly, to an improved structure of a detachable device for attaching a TV tuner for viewing a television using a liquid crystal display of a camcorder to a camcorder. A television tuner attachment and detachment device for a camcorder to provide stability of a connection.

In general, a camcorder refers to a camera that transfers and records an image or a moving subject at the time to a recording medium in order to record and store a moving image on a recording medium, which is generally called a 'camcorder'.

The camcorder basically visually checks a camera unit to which an operation or an image of a subject is input, a deck unit for recording contents input to the camera unit to a recording medium, that is, a video cassette, and an image input to the camera. It has a configuration consisting of a viewfinder unit for the purpose, of which the viewfinder unit in recent years mainly uses a liquid crystal screen that is small and easy to see with the naked eye.

In addition, since the LCD screen can be used as a cathode ray tube of a TV, a TV tuner (hereinafter referred to as a tuner) can be mounted on a camcorder equipped with the LCD screen to carry the camcorder regardless of location. You will be able to watch television.

Here, the above-described television tuner has a configuration for being mounted on or detached from a camcorder, and hereinafter, a television tuner detachment apparatus of a conventional camcorder will be described with reference to the accompanying drawings.

1 is an exploded perspective view showing a state where a television tuner is mounted on a conventional camcorder.

According to the drawing, the tuner has a pad shape which is portable by minimizing volume, and is made up of upper and lower cases 10 and 20. A detachable device for mounting on the camcorder 2 is provided on the upper surface of the upper case 10. It is composed.

The detachable device has a mounting rail 30 formed at a predetermined height so as to fit the engaging hole 3 having the locking jaw formed on the bottom surface of the camcorder 1 in the upper case 10 of the tuner 1, and the mounting rail 30. The engaging jaw 31 is formed at one side of the predetermined position in the predetermined position to prevent the coupler 3 from being displaced, and to have an elastic action inside the tuner 1 so as to enter and exit the camcorder. In order to remove the tuner 1 in the release button 33 for releasing the locking jaw 31 is installed in a predetermined position of the case is configured.

Here, reference numeral 34 denotes terminals for electrically connecting the tuner 1 and the camcorder 2, so that the terminals 34 have a stable connection force. Spring (not shown) is installed as an elastic member that pushes) upwards, and this spring is manufactured to have a strong elastic force to maintain a more stable connection for a long time because its elastic force should not change even after long use. .

The locking jaw 31 is such that the locking jaw 31 of the "c" shaped mounting rail 30 is formed only on one side, and for this reason, the tuner 1 performs the same tuning operation as that of a general television. At the same time, this is because a predetermined space is formed on one side inside the tuner 1 because it has to be manufactured in a small size in proportion to the size of the camcorder 2, which is well known.

Such a conventional tuner detachment device is provided with a spring with a strong elastic force in the lower portion of the terminal, the following problem occurs because the locking step is formed on only one side.

The mounting rail is formed at the bottom of the camcorder so that the camcorder fits naturally, and the predetermined rail is formed to have more space than the portion inserted into the rail. When the terminal of the camcorder and the terminal of the tuner are connected, The spring acts to press the bottom of the camcorder in the rail, so that the tuner on which the mounting rail is formed maintains a predetermined distance from the bottom of the camcorder due to the repulsive force pushing the camcorder.

This predetermined interval is an element of an unstable coupling state caused by deviation of the tuner, shaking, or the like when the camcorder and the tuner are coupled.

Therefore, when the jamming jaw is formed on only one side, if the shaking or tuner is about to be disengaged from the camcorder, the jamming jaw supports only one side of the part fitted to the mounting rail on the bottom of the camcorder, and thus the supported part is As a starting point, the tuner's shaking and deviating position continuously occur.

As a result, the tuner's shaking and deviation from the position of the tuner may cause connection failure or uneven wear of the jaw, and the bad connection caused as described above not only adversely affects the reliability of the product, but also occurs when uneven wear occurs. The jaw is easily broken even by a small external force, so that it cannot perform a predetermined role, and thus, a problem occurs because the jaw must be frequently replaced.

Accordingly, the present invention has been made in order to solve such a problem, and in mounting the television tuner to the camcorder, the structure of the detachable device installed in the tuner is improved, so that the tuner is more stably mounted to the camcorder, and thus the camcorder An object of the present invention is to provide a TV tuner detachable device of a camcorder in which the electrical connection between the terminals of the tuner and the tuner is also improved.
