Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, relates in particular to a kind of electric connector with high speed.

[background technology]

Nowadays, the electronics technology development is very fast, computer also develops into volume notebook less, easy to carry by desktop PC, and each corner in the ubiquity society, and when the user desires to carry out the transmission of data, signal or is connected with other ancillary equipment, promptly need so-called peripheral interface, use and generally peripheral interface is the most generally and widely popular on the market, still just with universal serial bus (Universal Serial Bus, USB), have more the function of hot plug (HotPlug) as main flow.

Yet, if stability with data transmission bauds and power supply supply thereof, early stage USB2.0 standard (USBHi-Speed) transmission speed rises to 480Mbps from 12Mbps, be only applicable to the ancillary equipment that driving electric is less and the transmission speed requirement is also not high (as: calculating punch, printer, carry-on dish, the networking telephone and network camera etc.), for circumscribed high storage capacity hard disk or DVD cd-rom recorder, player, or even up-to-date blue light technology etc., its transmission speed is obviously not enough, driving running power shortage will be maximum technical bottleneck place undoubtedly; Therefore, just there is the dealer to develop USB3.0 standard of future generation (USBSuper-Speed), the highest transmission speed of each USB3.0 connector can reach 4.8Gb ps simultaneously, not only physical characteristic is compatible with USB2.0 connector (promptly increasing by row's terminal group on US B2.0 connector basis satisfies required), and support transmitted in both directions (Full Duplex) significantly to improve transmission speed, power supply capacity stronger (900mA) is just meaning circumscribed high storage capacity hard disk will seldom use extra power supply, also can connect more ancillary equipment, and possess high-effect and can carry out interrupt mode under the holding state, effectively reduce characteristics such as power consumption, and then the elasticity and the usefulness of user's the best can be provided.

Yet, along with the function of terminal electronic product significantly improves, for for interconnective USB2.0 connector between the terminal electronic product, its signal transmission rate and quality certainly will improve and more stable relative, constitute the USB3.0 connector so promptly increase by row's splicing ear, satisfy aforesaid effect with this in the insulating base frame inside of existing USB2.0 connector.But insulating base frame will make that inner grafting space is quite limited after increasing by row's splicing ear, and cause terminal group to set the degree of difficulty and inconvenience of position, and structural stability is relatively poor, can't guarantee to make the locating effect that repeatedly plug is docked with aerial lug; In addition, the distance between each terminal is more approaching, will influence the quality and the stability of its signal transmission simultaneously, thereby produces the frequency electromagnetic waves that disturbs the electronic building brick on other circuit board.

Therefore, be necessary to design a kind of electric connector that overcomes above-mentioned defective.
