Description

Miniature HDMI connector

Technical field

The utility model relates to a kind of connector, relates in particular to a kind of connector of miniature HDMI (High Definition Multimedia Interface).

Background technology

HDMI (High Definition Multimedia) promptly is a HDMI (High Definition Multimedia Interface).The HDMI interface can provide the transfer of data broadband up to 5Gbps, can transmit audio signal and the high-resolution vision signal of not having compression.Need not simultaneously to transmit advance capable D/A or mould/number conversion, can guarantee that the video-audio signal of first water transmits at signal.

When video-audio signal transmits, only need a HDMI line just can transmit video-audio signal simultaneously, and unlike needing many wire rods to connect now.When carrying out D/A or mould/number conversion, can obtain higher Voice ﹠ Video transmission quality.For the consumer, the HDMI technology can not only provide image quality clearly, adds audio/video and adopts same cable, has simplified the installation of household audio and video system greatly.

In order to cooperate high-quality video-audio signal transmission wire, on many audio-visual electric equipment products, all can set up one group of HDMI connector, allow the user can connect the HDMI transmission line and use.Traditional HDMI connector is made of insulating body, metal cover body and conducting terminal usually, after conducting terminal and insulating body winding, insulating body is connected to metal cover body inside again.In use, the pin that conducting terminal is extended the metal cap external body is electrically connected with the circuit board of device, after the terminal of audio-visual transmission line was pegged graft by interface, video-audio signal was transferred on the circuit board by conducting terminal, and the circuit board that makes the video-audio signal of external device (ED) transfer to device is handled.

At present, the conducting terminal of the HDMI connector on the market is all adopted international standards, wherein, the HDMI interface can be supported 1600 * 1200 resolution, be to use the HDMI electric connector, it has 19 conducting terminals (pin position), and conducting terminal generally adopts the formula of sticking together of upright board plug type or level to be welded on the circuit board.

Adopt the HDMI connector of board plug type welding, the pin of its conducting terminal all vertically inserts circuit board to weld.The HDMI connector of the type generally needs the additional terminal board that respective perforations is passed for the pin of conducting terminal that be provided with, thereby before connecting HDMI connector and circuit board, by the pin of terminal board fixed conductive terminals, and then the speed of welding and the success rate of raising pin and circuit board.

Yet after the Miniature HDMI specification issue along with a new generation, the volume of Miniature HDMI is littler than HDMI, is applicable to stress compact portable electronic product.The conducting terminal factor amount of the HDMI connector of the above-mentioned type is many, and terminal board will be provided with the perforation with fixed conductive terminals of respective numbers, and its volume is bigger, thereby can not satisfy the requirement of HDMI connector miniaturization.

And the employing level is sticked together the HDMI connector of formula welding, and the equal along continuous straight runs of the pin of its conducting terminal stretches out, and is arranged in delegation in same plane.This HDMI connector adopts surface installation technique (Surface Mounted Technology, SMT also claim to stick together formula) to be arranged on the circuit board.The pin of this conducting terminal does not need extra parts that it is fixed before welding, can satisfy the requirement of HDMI miniaturization.

Yet, the conducting terminal of the HDMI connector of the above-mentioned type is because a plurality of pins become delegation to arrange, spacing between the pin is less, thereby increased the HDMI connector and be welded in difficulty on the circuit board, and, the solder(ing) paste of pad locations fuses easily, causes forming short circuit between the different conducting terminals, and product is worked the mischief.

The utility model content

The purpose of this utility model is to provide a kind of Miniature HDMI connector at above-mentioned the deficiencies in the prior art, this Miniature HDMI connector can satisfy the requirement of HDMI connector miniaturization, can effectively avoid producing because of the conducting terminal overmatter problems such as contact short circuit again.

For achieving the above object, Miniature HDMI connector that the utility model provides is suitable for being welded on the circuit board, comprises insulating body and a plurality of conducting terminal, and described insulating body is provided with a plurality of terminal containing slots; Described a plurality of conducting terminal correspondence is accommodated and is fixed in described a plurality of terminal containing slot, described a plurality of conducting terminal comprises some first conducting terminals and some second conducting terminals, each described first conducting terminal has first welding foot of perpendicular circuit board, to pass the circuit board welding, each described second conducting terminal has second welding foot of parallel circuit boards, to weld with circuit board surface.

As mentioned above, the utility model Miniature HDMI connector is because second welding foot of first welding foot, second conducting terminal perpendicular to circuit board of first conducting terminal is parallel to circuit board, thereby under the prerequisite that satisfies the miniaturization of HDMI connector, can effectively avoid producing problems such as contact short circuit because of the conducting terminal overmatter.
