Abstract

A tuner is provided to dispose an antenna input terminal and a loop through terminal on different surfaces of a chassis at a right angle with each other, thereby easily connecting an outside antenna line to the antenna input terminal. A tuner(21) comprises an antenna input terminal(212) formed at a corner of one surface of a chassis(211) and a loop through terminal(213) adjacent to the antenna input terminal. The antenna input terminal is connected to an outside antenna line. The antenna input terminal and the loop through terminal are disposed on different surfaces of the chassis while the antenna input terminal crosses at right angle with respect to the loop through terminal.

The present invention relates to a tuner.

In general, a tuner is a device that receives a high frequency signal through an antenna, converts it into an intermediate frequency signal, detects it, and separates it into a video signal and an audio signal. The tuner prevents frequency radiation generated from a local oscillator provided therein. It is formed of a chassis of a rectangular body that prevents adverse effects of external noise, and has an electric circuit therein.

In the tuner configured as described above, an antenna input terminal is formed at one edge of the chassis, and a high frequency signal is input from an external antenna line connected to the tuner. Is passed to the set via

Recently, two broadcasts have been received and one broadcast is watched while the other broadcasts through a loop-through, or a picture-in-picture (PVR) function for viewing both broadcasts on one screen. As shown in FIG. 1, the tuner 10 capable of performing the PIP function has an external antenna line at one side edge of the chassis 11 of the rectangular body that prevents frequency radiation and prevents adverse influences due to external noise. An antenna input terminal 12 connected thereto; And a loop through terminal 13 which is separately outputted to record the high frequency signal input from the external antenna line at a position adjacent to the antenna input terminal 12.

The tuner 10 configured as described above is typically mounted at the rear lower portion of the device, and the tuner 10 is mounted by soldering in a horizontal direction with the printed circuit board of the set.

However, the connection positions of the printed circuit board of the device and the antenna input terminal 12 of the soldered tuner 10 are not matched with the external antenna wires introduced into the rear lower part of the device, and therefore, should be connected using a separate connection means. In addition, there is a problem in that the tuner 10 needs to be connected to an external antenna line by changing the position.

In view of recent trends in slimming and miniaturization of video devices such as LCD or PDP TVs, set-top boxes, PC monitors, and the like, the tuner 10 mounted on the video device includes the antenna input terminal 12 and the loop through terminal 13. ) Is mounted so as to face downward of the video device, the external antenna line connected to the antenna input terminal 12 is troublesome in the connection work of the external antenna line to be connected from the lower side upward to the lower rear of the set.

The present invention facilitates the connection of external antenna lines to the tuner.

The present invention includes an antenna input terminal to which an external antenna line is connected to one side edge portion of the chassis; A tuner including a loop through terminal at an adjacent position of the antenna input terminal is configured such that the antenna input terminal is rotated 90 degrees with respect to the other side of the antenna through the loop through terminal.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 is a perspective view of a tuner according to an embodiment of the present invention.

The tuner 21 includes a chassis 211 having a rectangular body shape which prevents frequency radiation and prevents adverse effects due to external noise; An antenna input terminal 212 coupled to an external antenna line at one side edge of the chassis 211 to input a high frequency signal; It consists of a loop through terminal 213 for distributing the high frequency signal input from the antenna input terminal 212 to the outside.

The antenna input terminal 212 is configured to be perpendicular to the roof through terminal 213 rotated 90 degrees to the other side.

The present invention configured as described above comprises an antenna input terminal 212 in which an external antenna line is coupled to the chassis 211 of the tuner 21 at a right angle with the roof through terminal 213 rotated 90 degrees to the other side. When the tuner 21 is mounted on the rear lower portion of a slimmer and miniaturized video device such as an LCD or a PDP TV, a set-top box, and a PC monitor, the antenna input terminal 212 of the tuner 21 is placed in front of the rear portion. It can be mounted so as to be exposed, the external antenna line can be easily connected to the antenna input terminal 212 of the tuner 21 from the rear front.

In addition, the present invention can directly connect the external antenna line to the antenna input terminal 212 of the tuner 21, so that no additional means is required to connect the external antenna line, it is convenient for installation work In addition, it takes up less space for installation, making it slimmer and smaller.

As described above, the present invention forms an antenna input terminal to which an external antenna line is connected to a chassis of a tuner that converts an input high frequency signal to an intermediate frequency in a right angle rotated 90 degrees to a loop through terminal and the other side. The antenna input terminal of the tuner is mounted to the rear of the front of the video equipment to easily connect the external antenna line, so that it is convenient for installation work and occupies less installation space, thereby providing the effect of slimming and miniaturization. will be.

Claims (3)
