Specific embodiment

In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only to explain The present invention, is not used to limit the utility model.

The utility model provides a kind of positive anti-plug data transmission connectors of USB, as illustrated in figs. 1 and 2, including insulation is originally Body, the shell 1 for being sheathed on the insulating body side, upper terminal 4, lower terminal 5, upper terminal 4 and lower terminal 5 are connected as end Son, and be inserted in insulating body, the socket end of terminal is the two rows formula structure for being capable of positive and negative grafting, is so designed The positive and negative function that can be inserted is capable of achieving, tail end is the row's formula structure for substituting pcb board.

As shown in Figure 3 and Figure 4, upper terminal 4 includes top base 42 and the upper end subgroup 43 being embedded in top base, top base 42 are extended along the both sides of the axis direction of upper end subgroup 43 and have the first fixed part 41, and lower terminal 5 includes bottom base 52 and is embedded Lower end subgroup 53 in bottom base, bottom base 52 is extended along the both sides of the axis direction of lower end subgroup 53 the second fixed part 51, the first fixed part 41 and the second fixed part 51 are arranged along upper terminal 4 and the tail end direction of lower terminal 5.

Insulating body is made up of upper jacket and lower jacket splicing, by the way that intrinsic sheath in prior art is changed to into upper and lower two panels Directly assembling split is carried out with terminal, realize terminal without the need for the function with plastic rubber shaping.
