Socket connector

Technical field

The utility model relates to a kind of socket connector, the socket connector of especially a kind of USB PD Standard-B (B-TYPE).

Background technology

The electric connector of USB (hereinafter to be referred as USB) specification is in daily life is used, it is one of transport interface of extensive use the most, therefore because facilitating of USB interface is easy-to-use, size is little and cost is reasonable, at be all the seen everywhere trace of USB of each different operating field domain.No matter be that the core entertainment device of family is as work active computer, the printer of TV, individual's notebook computer, intelligent mobile phone, board device or office, and even the multi-media communication entertainment systems of automobile, is all dependent on the task that USB carries out transfer of data often.

Except providing convenience, quick and reliable transfer of data, USB also has a function very easily, and that is exactly to interconnect to carry out electric power transfer, namely so-called charging by electronic multimedia device interface.Yet, current USB charging is the highest still can only be provided to the electric power of 7.5 watts, although confession electrical specification evolution like this can meet hand-hold type and can take device as the charging demand of mobile phone or music media player (MP3), but conventionally need consuming time longer, and wanting to meet large scale and need to consume relatively high power product as the power supply of screen display or notebook computer, is slightly to dislike not enough.

In order more to popularize the application of USB in different device power supply, and reduce the configuration of power line, brand-new USB electric power transfer (USB Power Delivery, USB-PD) is just arisen at the historic moment.The international ANSI (USB-IF) of formulating of USB has announced that in a few days ago this key name is that USB Power Delivery(is called for short PD) electric power transfer standard, be intended to by the electric power transfer amount up to 100 watts, allow various devices all can meet power demands by an independent USB cable, and shorten the advantage in device charging interval, more can optimize the convenience of mobile applications.Its basic technology framework is exactly the function storing by electric power in chipset, allow electric power be kept in, and transfer on the device that needs electric power, simultaneously, Power Delivery possesses amphitropic feature, on one side charge when carrying out transfer of data during allowing device, the practice easily that saves time promotes the efficiency that it uses more, and no longer need traditional power line, make power wire unitized.

In addition, the international ANSI (USB-IF) of formulating of USB also provides a kind of new Powered-B connector, and its main benefit is better portability.Powered-B connector allows to remove USB cable and extra power supply, as shown in Figure 9, TaiWan, China M364319 patent provides a kind of Powered-B socket connector, comprise an insulating body A1, it has relative the place ahead A101 and rear A102, and this insulating body A1 is provided with a body A11 and is connected in this body A11 and corresponding to a tongue piece A12 and a plate body A13 of this place ahead A101, one first conducting end subgroup A2, there is a plurality of the first conducting terminal A20 and a plurality of power supply terminal A30, each first conducting terminal A20 includes first A21 of our department, one first that is fixed on this body A11 and touches the first welding foot A23 that the A22 of portion and stretches out this body A11 rear A102, and first of this first conducting end subgroup A2 touches the A22 of portion and is positioned at two planes that this tongue piece A12 is relative, one second conducting end subgroup A4, there are a plurality of the second conducting terminal A40, each second conducting terminal A40 includes second A41 of our department, one second that is fixed on this body A11 and touches the second welding foot A43 that the A42 of portion and stretches out in this body A11 rear A102, and second of this second conducting end subgroup A4 touches the A42 of portion and is positioned at this plate body A13 towards the plane of this tongue piece A12, an and screening can A5, there is shielding this insulating body A1 and relative one first screening can A50 and the secondary shielding shell A60 in front and back, this the first screening can A50 and this insulating body A1 define the grafting space A54 of a tool socket A541 jointly, this secondary shielding shell A60 defines a shielding space A63 jointly at this insulating body A1 rear A102, the first welding foot A23 and the second welding foot A43 of this first conducting terminal A20 and this second conducting terminal A40 stretch into this shielding space A63, and each second welding foot A43 is adjacent to this secondary shielding shell A60, this the first screening can A50 and this secondary shielding shell A60 are provided with the first contact arm A51 and the second contact arm A61 of corresponding overlap joint contact.

Moreover, general socket connector carries out interference engagement by this first conducting end subgroup A2 with the corresponding contact terminal (not indicating in diagram) of a banjo (not indicating in icon), yet mutual clamping strength is too small between the two, cause being difficult for clamping buckle, and in above-mentioned socket connector structure, the inside dual-side of this first screening can A50 is respectively equipped with a metal clips A7, because this metal clips A7 easily touches this power supply terminal A30 when assembling, cause the short circuit of this power supply terminal A30 signal ground, add the cumulative rises of banjo (not indicating in icon) plug number of times, this metal clips A7 may and then produce diastrophic phenomenon because of elastic fatigue, easily there is the state that this socket connector cannot keep buckle to be combined with a banjo (not indicating in icon), therefore cause and produce upper problem to be solved.
