Abstract

The utility model relates to the technical field of an electric connector, and particularly to a bidirectional plugging type USB electric connector. The bidirectional plugging type USB electric connector comprises an insulating body and a housing. The insulating body is provided with a tongue which extends into a socket of the housing. A first terminal and a second terminal are combined on the insulating body. A contact part of the first terminal is divided into a left sub contact part and a right sub contact part. The left sub contact part and the right sub contact part are placed on the upper side and the lower side of the tongue and are staggered from each other. The contact part of the second terminal extends and is placed on the upper side and the lower side of the tongue. The contact part of the second terminal is coordinated with the left sub contact part and the right sub contact part of the first terminal for matching with outwards electric plugging, thereby obtaining bidirectional plugging performance. The width of the socket of the housing satisfies operation requirement of coordination bidirectional plugging between the first terminal and the second terminal. The bidirectional plugging type USB electric connector facilitates use and sufficiently utilizes different points on a terminal contact part for alternate use, thereby greatly prolonging service life of the connector and obtaining high performance-to-price ratio.

Below in conjunction with accompanying drawing the utility model is further specified:

Consult shown in Fig. 1 ~ 5, the relevant a kind of USB electric connector of the utility model, especially relate to USB3.0 type electric connector, it includes insulating body 1 and shell 2, shell 2 wrap insulate main bodys 1 also are formed with socket 21 in inserted terminal, described insulating body 1 is provided with the tongue piece 11 in the socket 21 that protrudes out shell 2, be combined with the first terminal 3 and second terminal 4 on the insulating body 1, two

sub-contact sites

31,32 about the contact site of the first terminal 3 is torn and is divided into, this two

sub-contact site

31,32 the be placed in upper and lower sides of tongue piece 11 and relatively dislocation; The contact site 41 of second terminal 4 extends tongue piece 11 upper and lower sides that are placed in, the contact site 41 of second terminal 4 and two sub-contact sites 31 of the

first terminal

3,32 cooperation are externally electrically pegged graft, obtain two-way plugging capability, and the width of the socket 21 of shell 2 satisfies the job requirement of the first terminal 3 and the two-way grafting of second terminal, 4 cooperation, the width that is socket 21 satisfies the two-way insertion connection of connection-peg, in the present embodiment, be provided with the shell fragment 22 of service hoisting contact engaging and separating force at the left and right sides of the socket 21 of shell 2, shell fragment 22 is the local punching out acquisitions by shell 2, inside press force is arranged, when connection-peg is inserted, shell fragment 22 suitable pressure holdings are to connection-peg, thereby obtain enough contact engaging and separating forces, reach grafting work.

The contact site of the first terminal 3 of the present utility model and second terminal 4 all is distributed in tongue piece 11 upper and lower sides, thereby no matter the outside is positive the insertion or the reverse side insertion to connection-peg, all can realize electrically conducting, reach the function of signal transmission, that is to say and the utlity model has two-way plugging capability, satisfy the two-way grafting of connection-peg, not only offer convenience to use, difference is used alternatingly in the termination contact portion but also take full advantage of, prolonged the useful life of connector greatly, have high performance price ratio; Simple in structure, to make easily, cost of manufacture is low, when satisfying the high-performance development of connector, returns the user and brings economical and practically greatly, is conducive to promote the development of electric connector.
