Abstract

The utility model relates to a structure improved television card, in particular to a television card used in a notebook computer. The television card used in a notebook computer comprises a circuit board and moderator. The circuit board can be inserted in a thin connector on a host board and the moderator can be positioned in a transparent groove on the circuit board, greatly reducing the height of the television card. If a television card of different specification is manufactured, such as an analog and a digital traditional television card or DVBT, DVBS and MCE special television cards, only moderator is needed to be replaced.

Description

Structure improved TV card

Technical field

The utility model relates to a kind of structure improved TV card, especially instigate the TV card that is used in the notebook computer, wherein this circuit board is provided with groove, and device has demodulator in the saturating groove, can make TV card effectively reduce thickness, and only need change demodulator, can reach the demand that is used in various different sizes.

Summary of the invention

Fundamental purpose of the present utility model is to overcome the deficiencies in the prior art and defective, utilizes the saturating groove on the circuit board, demodulator is installed on is welded into one in the groove, reduces the height of TV card with this.

Secondary objective of the present utility model is, utilizes the mode of groove to assemble, and when producing the TV card of different size (as simulation and digital traditional tv card or DVBT, DVBS, MCE special television card) as desire, only need change demodulator and get final product.

For reaching above-mentioned purpose, the utility model provides a kind of structure improved TV card, instigates the TV card that is used in the notebook computer especially, includes circuit board and demodulator is formed; Wherein: this circuit board one side is provided with a butt end, and is provided with several contacts in the butt end, and is provided with groove away from the opposite side of butt end, and a side of saturating groove is provided with several contacts; This demodulator one side is provided with the butt end, and is provided with several contacts in the butt end, and demodulator is placed in the saturating groove of circuit board, and the contact of butt end can be formed with the contact in the saturating groove of circuit board electrically connect; By above-mentioned, can make TV card effectively reduce thickness, and only need change demodulator, can reach the demand that is used in various different size TV card.
