In space 120, it is formed with stop surface 1310 between the adapter section 121,131 and the extended segment 122,132, in the cross
It is kept out the front side of beam 32.
The extended segment 122,132 of the upper and lower ontology 12,13 has the carrier 1221,1321 positioned at its rear end, described
The thickness of carrier 1221,1321 in the height direction is less than the thickness of extended segment 122,132 in the height direction on front side of it.
The snap close piece 3, which also has from the crossbeam 32, extends backward more than the rear surface of insulating body 1 for being welded in
Leg 34 on circuit board (not shown), so that snap close piece 3 has both earthing effect.In other embodiments of the invention,
According to the needs of application environment, the electric connector 100 can also not have the snap close piece.
The front end of the shielding casing 4 has the interface frame, mating frame mouth of ellipse, connect with the USB Type-C plug of standard
The interface frame, mating frame mouth of device is consistent, for the positive and negative insertion cooperation with butt-joint socket connector, just with the applicable use of positive anti-plug
Prompt sexual clorminance.
In the present invention, each metal clips 5, which has, is attached at the substrate 51 in 1 outside of the insulating body, from institute
The rear end for stating substrate 51 folds forward the interior of extension and supports elastic slice 53 and extend back to abut the outer of shielding casing 4 and support
Elastic slice 54, it is described in support elastic slice 53 towards riding out inside grafting space 110, the outer rear end for abutting elastic slice 54 is freely
End, and its rear end has towards the trend close to the shielding casing 4.
The above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to preferred embodiment to this hair
It is bright to be described in detail, those skilled in the art should understand that, it can modify to technical solution of the present invention
Or equivalent replacement, without departing from the spirit and scope of the technical solution of the present invention.
