Description

TV set and its tuner

The present invention relates to a television set, and more particularly to a tuner for a television set.

With the development of science and technology and the advancement of society, electronic devices such as televisions have played more and more roles in people's daily lives and work. While minimizing the size of the electronic device itself, and how to properly utilize the space when the electronic device is coupled with an externally connected accessory, it has also become a topic of great concern.

Generally, a television set includes a front frame, a rear case that is engaged with the front frame, and a display screen, a printed circuit board, a tuner, and the like housed between the front frame and the rear case. Among them, the display is located at the front end of the TV. In order to reduce the thickness of the television set, the printed circuit boards are placed in parallel on the rear surface of the display screen. The front surface of the tuner is placed in parallel on the rear surface of the printed circuit board. The tuner includes a main body in which the circuit module is disposed, and a pin and a cable interface respectively located on opposite surfaces of the main body. Wherein, the pin is used for connecting to the printed circuit board, and the cable interface extends in a direction perpendicular to the front surface of the main body and is exposed through the rear case for connecting the cable. In use, the high frequency signal enters the tuner from the cable, is converted to an intermediate frequency signal by the tuner, and finally transmitted to the printed circuit board.

When used, people usually hang TV sets on the wall or placed against the wall. The cable is connected to a cable interface that is exposed through the rear case. However, the cable connecting the cable interface is usually thick and cannot be bent at will. If it is forced to bend, it will affect the normal transmission of the signal. Therefore, in order to ensure the normal transmission of the signal, a large distance between the TV and the wall is required to facilitate the connection of the cable.

In view of this, it is necessary to provide a television set that can reasonably utilize space.

It is also necessary to provide a tuner that makes reasonable use of space.

A television set includes a housing and a display screen and a tuner received in the housing, the tuner includes a body, a cable interface disposed on a surface of the body, and the cable interface passes through the housing for connecting the cable, the wire The angle between the extension of the cable interface and the plane of the display screen is an acute angle.

A tuner includes a body, a pin disposed on the first surface of the body, and a cable interface on the second surface, the cable interface is configured to connect the cable, and the extending direction of the cable interface is at an acute angle with the first surface .

Since the extending direction of the cable interface on the tuner is at an acute angle to the angle between the display screen and the first surface, when the cable is inserted into the cable interface, the cable can be prevented from extending in a direction perpendicular to the display screen, thereby While ensuring the normal transmission of the signal, the distance between the TV and the wall is reduced, and the space is effectively utilized.

2 is a partial circuit diagram of the power module of FIG. 1.

Figure 3 is a side elevational view of the tuner of Figure 2.

4 is a view showing a state of use of the television set of FIG. 1.

1 is a partial cross-sectional view of a television set 100 in accordance with a preferred embodiment. The television set 100 includes a front bezel 10, a rear case 20 that is engaged with the front bezel 10, and a display screen 30, a printed circuit board 40, and a tuner 50 that are housed between the front bezel 10 and the rear case 20. In use, the front frame 10 is adjacent to the viewer, and the rear case 20 is remote from the viewer and near the wall 70 (as shown in Figure 4). Among them, the display screen 30 is located at the front end of the television set 100, and its front surface faces the viewer. The printed circuit board 40 is disposed parallel to the display screen 30 and has opposing first side faces 41 and second side faces 43, wherein the first side face 41 is opposite the rear face of the display screen 30. The tuner 50 is disposed on the second side 43 of the printed circuit board 40.

As shown in FIGS. 2 and 3, the tuner 50 includes a body 51, a lead 53 and a cable interface 55 in which a circuit module is disposed. The circuit modules within the body 51 typically include input filters, single tuned circuits, dual tuned circuits, amplifiers, hybrid circuits, and the like that only allow high frequency bandwidth to pass. The body 51 has a first surface 511, a second surface 517, a third surface 515, and a fourth surface 513. The first surface 511 is a flat surface, the third surface 515 is connected between the fourth surface 513 and the second surface 517, and the second surface 517, the third surface 515 and the fourth surface 513 are integrally formed in a bent shape. The fourth surface 513 is parallel to the first surface 511. The third surface 515 extends from the end of the fourth surface 513 with respect to the first surface 511. The angle between the fourth surface 513 and the first surface 511 is β, and β is an acute angle. The second surface 517 extends from the end of the third surface 515 in a converging direction with respect to the first surface 511 and is perpendicular to the third surface 515.

A pin 53 is located on the first surface 511 for connecting the printed circuit board 40. Pin 53 usually includes an intermediate frequency signal pin, a power supply pin, a data input and output pin, and the like. The intermediate frequency signal pin is used for outputting an intermediate frequency signal converted from a high frequency signal, the power supply pin is used to supply power to the circuit, and the data input and output pin is used as an interface between the tuner circuit and the television circuit board. .

The cable interface 55 is located on the second surface 517 and extends perpendicularly from the second surface 517 for connecting the cable. The cable interface 55 is at an angle α with the first surface 511. Because the angle between the third surface 513 and the first surface is β, and the second surface 517 is perpendicular to the third surface 515, the extending direction of the cable interface 55 is perpendicular to the second surface 517, so the angle α and the angle of the angle α When β is equal, the angle β is an acute angle, and the angle α is an acute angle. Considering the positional relationship between the cable interface 55 and the rear case 20 and the distance between the television set 100 and the wall, the preferred range of the included angle α is 10° to 45°. In the present embodiment, the angle α is 20°.

Because the first surface 511 of the tuner 50 is parallel to the second side 43 of the printed circuit board 40 and opposite the second side 43 of the printed circuit board 40, the printed circuit board 40 is in turn disposed parallel to the display screen 30. Therefore, the angle between the extending direction of the cable interface 55 and the printed circuit board 40 and the display screen 30 is equal to the magnitude of α, that is, the surface of the cable interface 55 relative to the printed circuit board 40 or the display screen 30 is from the fourth surface. The 513 extends obliquely out.

As shown in FIG. 4, when the tuner 50 is disposed inside the television set 100, the cable interface 55 is exposed through a hole (not shown) in the rear case 20. When in use, the television set 100 is usually placed against the wall 70 or hung on the wall 70, and the cable 60 is electrically connected. The rear side of the video camera is inserted into the cable interface 55. The high frequency signal is transmitted from the cable interface 55 to the inside of the tuner 50 and converted to an intermediate frequency signal by the circuit module in the tuner 50, and then transmitted from the pin 53 to the printed circuit board 40.

Because the angle between the extending direction of the cable interface 55 on the tuner 50 and the surface on which the first side 511, the printed circuit board 40, and the display screen 30 are located is an acute angle. Therefore, when the cable 60 is inserted into the cable interface 55, the problem of the cable 60 being inserted from the direction perpendicular to the display screen 30 can be avoided. At this time, the cable line 60 does not need to be bent, and therefore, the distance between the television set 100 and the wall 70 can be reduced while ensuring the normal transmission of the signal, and the space can be effectively utilized. In addition, the cable 60 is inserted into the cable interface 55 of the tuner 50 obliquely relative to the display screen 30, which is more ergonomic.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above descriptions are only preferred embodiments of the present invention, and those skilled in the art will be able to include equivalent modifications or variations in the spirit of the present invention.
