  The present invention relates to an electrical connector, and more particularly to an electrical connector having a plurality of audiovisual interfaces.

  With the development of the computer industry, electrical connectors have become indispensable electronic components. Among them, a plurality of pins can be installed on the electrical connector to perform signal transmission of the audiovisual interface. There are an array (Video Graphics Array, VGA), a digital visual interface (Digital Visual Interface, DVI), an HDMI (High Definition Multimedia Interface), and the like. Electrical connectors are usually mounted on a specific printed circuit board. Various electronic members installed on the printed circuit board can receive a signal of an electronic device or transmit a signal to the electronic device for the first time through an electrical connector.

  In the ages mainly based on CRT (Cathode Ray Tube) displays, digital signals in graphic cards can be presented on the screen for the first time after being converted into analog signals via VGA. It causes signal degradation and produces distortion effects.

  With the advancement of hardware technology, the pursuit for pure digital is constantly rising, the DVI standard emerges, and since DVI is a fully digital transmission method, the display can be received directly in digital format, once The conversion process is reduced and the display quality is significantly improved.

  To date, DVI has already become a bottleneck, and many companies such as Sony, Hitachi and Matsushita have jointly developed HDMI. HDMI improves the defect of the audiovisual interface and can directly transmit uncompressed video data and audio data. Various electronic devices such as set-top boxes, radios, digital TVs, monitoring devices, projectors, and the like can all transmit data to each other using HDMI.

  However, DVI or HDMI standards are not questioned in current market requirements because each has its marketability. Therefore, since the types and functions of the various audiovisual interfaces are different, how to integrate them is an actual trend.

The plurality of video / audio interfaces include a video graphic array, a digital visual interface, and HDMI. The transmission line is electrically connected to the plurality of pins, a plurality of signal lines are installed inside the transmission line, and one signal line is used for signal transmission of one video / audio interface. The plurality of plugs are electrically connected to the signal lines, each one plug is electrically connected to one signal line, and each one plug is used for signal transmission of one audiovisual interface.

  In the electrical connector having the plurality of audiovisual interfaces, the display includes a liquid crystal display, a plasma display, and a projection display.

  In the electrical connector having the plurality of audiovisual interfaces, the main body is made of an insulating material.

  In the above electrical connector having a plurality of audiovisual interfaces, the main body is molded integrally with the pin socket.

  In the electrical connector having the plurality of audiovisual interfaces described above, the transmission line and the plurality of plugs are integrally molded.

  In the electrical connector having a plurality of audiovisual interfaces as described above, each one plug has one insertion port, and the insertion port is connected to an electronic facility and transmits a signal of the electronic facility to the display. The display signal is transmitted to the electronic equipment.

  As described above, the electrical connector having a plurality of audiovisual interfaces according to the present invention realizes signal transmission of a plurality of audiovisual interfaces, and some of the pins in the video graphic array, digital visual interface, and HDMI standards. Since the definition is the same, some pins can be shared. Therefore, the present invention unifies a plurality of audiovisual interfaces and improves the convenience in use, and also reduces the manufacturing cost. You can also.

It is structure explanatory drawing of the electrical connector which has the several audiovisual interface of this invention. It is an enlarged view of the detail of the pin socket of this invention.

  In order to facilitate understanding of the above object and other objects, features, and advantages of the present invention, examples are given below and described in detail with reference to the drawings.

  FIG. 1 is an explanatory view of the structure of an electrical connector having a plurality of audiovisual interfaces according to the present invention. Referring to FIG. 1, the present invention provides an electrical connector 1 having a plurality of audiovisual interfaces and is applied to a display, which includes a liquid crystal display, a plasma display, and a projection display. The electrical connector includes a main body 11, a transmission line 12, and a plurality of plugs 13. The main body 11 is installed on the display, a pin socket 111 is installed on the main body 11, a plurality of pins 112 are installed on both sides of the pin socket 111, and the plurality of pins 112 are a plurality of video and audio. The plurality of audiovisual interfaces used for interface signal transmission include a video graphics array (Video Graphics Array, VGA), a digital visual interface (Digital Visual Interface, DVI), and an HDMI (High Definition Multimedia Interface, HDMI). Including.

  The transmission line 12 is electrically connected to the plurality of pins 112, a plurality of signal lines 121 are installed inside the transmission line 12, and each one signal line 121 performs signal transmission of one audiovisual interface. Used for. The plurality of plugs 13 are electrically connected to the transmission line 12, each one plug 13 is electrically connected to one signal line 121, and each plug 13 is used for signal transmission of the audiovisual interface. .

  Of these, the main body 11 is made of an insulating material, the main body 11 and the pin socket 111 are integrally molded, and the transmission line 12 and the plurality of plugs 13 can also be integrally molded. Each one plug 13 has an insertion slot 131, which is connected to an electronic facility and transmits a signal of the electronic facility to the display or transmits a signal of the display to the electronic facility. .

  FIG. 2 is an enlarged detail view of the pin socket. Referring to FIG. 2, in the embodiment, the number of the plurality of pins 112 installed in the pin socket 111 may be 35. The plurality of pins 112 can be arranged in order according to functional demands or industry-standard standards. In the video graphic interface, digital visual interface, and HDMI standards, some pins have the same definition, so some pins can be shared. In addition, when one video / audio interface among the plurality of video / audio interfaces is used due to the function of the display itself, the other video / audio interfaces cannot be used, and the influence on the sharing of the plurality of pins is avoided. can do.

  DVI has a plurality of standards, and includes DVI-A (transmits only analog signals), DVI-D (transmits only digital signals) and DVI-I (can transmit digital and analog signals), and DVI-A Etc. are the same as VGA. DVI-D and DVI-I can be further divided into a single channel and a dual channel, and the signal transmission rate of the dual channel can be twice as fast as that of a single channel. HDMI also has multiple standards, including single-channel HDMI-A and dual-channel HDMI-B.

  Therefore, in the pin design, the first pin 112 to the sixth pin 112 of the electrical connector 1 can be used for signal transmission of VGA (same as DVI-A). The first pin 112 to the 27th pin 112 and the 31st pin 112 to the 35th pin 112 can perform dual channel DVI-I signal transmission. The first pin 112 to the 18th pin 112 and the 31st pin 112 to the 35th pin 112 can be used for signal transmission of a single channel DVI-I.
