Embodiment

Below in conjunction with accompanying drawing, be described in more detail with other technical characterictic and advantage the utility model is above-mentioned.

Please refer to Fig. 1 to Fig. 5, the two agreement Miniature plug connectors of the utility model are exclusively used in the socket connector of Mini-B type and are not suitable for the USB socket connector of A type, Type B or other shapes.In addition, the utility model can be supported the host-host protocol (under the framework based on Mini-B type USB connector) of USB2.0 (under the framework based on Mini-B type USB connector) and USB3.0 simultaneously, also can be installed on the transmission line.Described transmission line other end can connect other electronic installations or another joint, carries out the transfer of data operation between two electronic installations thus.

The two agreement Miniature plug connectors of the utility model include: an insulating body 10, a first terminal group 30, one second terminal group 50, a circuit board 60, a screening can 70 and an insulating case 80.

Described insulating body 10 has a pedestal 11, and projection forms one first tongue piece 13 and one second tongue piece 15 forward on pedestal 11.Can be formed with a gap between first tongue piece 13 and second tongue piece 15 so that stretch into described gap for the tongue piece in the corresponding socket connector.

Described the first terminal group 30, it is arranged on the insulating body 10, and has and a plurality ofly run through pedestal 11 and be arranged on the first terminal 31 on first tongue piece 13.Described a plurality of the first terminal 31 can be Mini-B type USB2.0 terminal, and can be arranged at the lower surface of first tongue piece 13.

Described second terminal group 50 is to have a plurality ofly to run through pedestal 11 and be arranged on second terminal 51 on second tongue piece 15.Described a plurality of second terminal 51 can be Mini-B type USB3.0 terminal, and can be arranged on the upper surface of second tongue piece 15.In addition, above-mentioned all second terminals, 51 all the first terminals 31 of palpus collocation could be carried out the host-host protocol of USB3.0.

Though the first terminal group 30 and second terminal group 50 lay respectively on first tongue piece 13 and second tongue piece 15, yet the configuration after two-terminal group upper-lower position exchanged also is within the category of the present utility model.

Described circuit board 60 is arranged in the pedestal 11 of insulating body 10, and includes the insulation cushion 61 of a plurality of corresponding the first terminals and corresponding second terminal, and each insulation cushion 61 is between the corresponding the first terminal and second terminal.Circuit board 60 can supply the copper conductor of welding transmission line, and makes copper conductor be connected so that can transmit operation with

corresponding terminal

31,51.

Described screening can 70 is a metallic, covers insulating body 10, the first terminal group 30 and second terminal group 50, is formed with a Mini-B type Plug Division 700 to connect socket connector of the same type on screening can 70.Described Mini-B type Plug Division 700 can be inserted among the Mini-B type USB socket connector of metric system to reach the purpose of electric connection.But Mini-B type Plug Division 700 is the first half and Lower Half according to width distinguishing, and first half width reaches foolproof function thus greater than the Lower Half width.In addition, screening can 70 can be made up of a upper half shell 71 and a lower half shell 72, and Mini-B type Plug Division 700 then is formed on upper half shell 71 front ends.In addition, upper half shell 71 and lower half shell 72 be provided with a plurality of button holes with cramp so that fasten mutually, and then combine closely upper half shell 71 and lower half shell 72.

Described insulating case 80 coats screening can 70 and makes the Mini-B type Plug Division 700 of screening can 70 expose to insulating case 80 front ends.Insulating case 80 screening can 70 that can the injection molding mode closely be coated and fixed strengthens the structural strength of Miniature plug connector integral body thus, avoids unexpected situation of disintegrating, and the intensity that can promote anti-plug, and increase plugs number of times.

In addition, as Fig. 5, shown in Figure 6, all

terminals

31,51 can be weaved into the 1st to 10a numbering 1-10a in regular turn, and each

terminal

31,51 signal that had of numbering 1-10a is defined as follows table.
