Description

HDMI electrical connector that complies with DisplayPort signal contacts

The present invention provides an HDMI electrical connector that complies with the DisplayPort signal contact, in particular, an HDMI electrical connector in which the 16th terminal at the bottom row and the 17th terminal at the top row form an interlaced structure; the 18th terminal at the bottom row and the 19th terminal at the top row form an interlaced structure, so as to form a HDMI electrical connector that is compatible with the DisplayPort interface circuit board by changing the terminal pin arrangement, thereby achieving the purpose of being compatible with DisplayPort and HDMI electrical connectors on the same circuit board.

Electrical connectors are widely used in various communication and audio-visual equipment as transmission and connection components of electronic signals. Common standard connector sockets include RJ-11 (telephone line socket), RJ-45 (network line socket), USB (Universal Serial Bus), IEEE1394 (Serial Bus), RF (Wireless Transmission Port), Pin-header, HDMI (High Definition Multimedia Interface) and DisplayPort (Display Port) and many other types.

Among the above electrical connectors, HDMI (High Definition Multimedia Interface) and DisplayPort (DP) connectors are widely used for image signal transmission, but DisplayPort and HDMI belong to different transmission protocols. The difference is that DisplayPort electrical connector has 20 terminals, while HDMI has 19 terminals, and the definition of each terminal pin of the two is also different. At the same time, the docking structure and tongue shape of the two are different, so they cannot be compatible with docking to produce electrical connection. However, in general electronic audio-visual equipment, if you want to set the solder pads of DisplayPort and HDMI on the circuit board installed inside it through circuit layout, it will inevitably increase the area of the circuit board. For electronic audio-visual equipment that pursues lightness, thinness and compactness, its volume must also be increased. Therefore, how to design a connector on a circuit board that is compatible with both DisplayPort and HDMI has become a problem that those in the industry are eager to solve.

Therefore, in view of the above problems and deficiencies, the inventor collected relevant information, evaluated and considered various aspects, and used the years of experience accumulated in this industry, and after continuous creation and modification, he finally designed the invention patent of this HDMI electrical connector that complies with the DisplayPort signal contact.

The present invention is mainly an HDMI electrical connector that complies with the DisplayPort signal contact point. The HDMI electrical connector can be soldered on 20 parallel solder pads on the DisplayPort interface circuit board. The HDMI electrical connector includes: the HDMI electrical connector has ten parallel terminals from the upper row from right to left, which are odd-numbered from the 1st to the 19th pins, wherein the soldering portion of the 17th pin terminal is located at the 16th solder pad position of the DisplayPort interface circuit board; and the 19th pin terminal is located at the 18th solder pad position of the DisplayPort interface circuit board; the HDMI electrical connector has an odd-numbered solder pad from the 1st to the 19th pin terminal; and the HDMI electrical connector has an odd-numbered solder pad from the 1st to the 19th pin terminal. The connector has nine parallel terminals in the lower row, which are even-numbered from the 2nd to the 18th pins from right to left. The soldering portion of the 16th pin terminal is located at the 17th solder pad position of the DisplayPort interface circuit board; and the soldering portion of the 18th pin terminal is located at the 19th or 20th solder pad position of the DisplayPort interface circuit board. The bent terminals in the upper and lower rows are used to change the soldering position on the DisplayPort interface circuit board, so that when the HDMI electrical connector is soldered on the DisplayPort interface circuit board, all terminals can obtain correct electrical connection signals. By forming a staggered structure with the aforementioned 16th pin terminal in the lower row and the 17th pin terminal in the upper row, and forming a staggered structure with the 18th pin terminal in the lower row and the 19th pin terminal in the upper row, a HDMI electrical connector is formed to be compatible with a DisplayPort interface circuit board by changing the arrangement of the terminal pins, thereby achieving the purpose of being compatible with DisplayPort and HDMI electrical connectors on the same circuit board.

The secondary purpose of the present invention is to make the 19th or 20th solder pad position of the DisplayPort interface circuit board a vacant position without any terminal soldered.

Another purpose of the present invention is to define the 16th pad position of the DisplayPort interface circuit board as ground; the 17th pad position as differential negative signal; the 18th pad position as hot plug detection; the 19th pad position as connector power response; and the 20th pad position as connector power.

Another purpose of the present invention is to form a staggered structure in the HDMI electrical connector with the 16th pin terminal in the lower row and the 17th pin terminal in the upper row.

Another purpose of the present invention is to form a staggered structure in the HDMI electrical connector with the 18th pin terminal in the lower row and the 19th pin terminal in the upper row.

The two side panels 31 of the shielding shell 3 each extend downwardly with a plurality of positioning feet 311 and a fixing arm 312 protrudes toward the rear panel 32. Through the fixing structure of the rear panel 32 and the two fixing arms 312, when the plug and socket electrical connectors are connected, the insulating body 1 will not be pushed backward by the plugging stress and thus be separated from the shielding shell 3.
