Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings.

Fig. 1 is an exploded perspective view of a preferred embodiment of the present invention, and is shown with reference to other figures, as will be apparent from the drawings, the present invention is mainly composed of: the insulating base 1, the shielding shell 4, and the first terminal set 2 and the second terminal set 3 fixed on the insulating base 1; the insulation seat body 1 comprises a base 11, a tongue 12 extending forwards from the base 11, and two side projections 14 extending backwards from the base 11, and an accommodating part 15 is defined between the two side projections 14, a long channel 13 is arranged on the tongue 12 for the second terminal set 3 to be inserted, and positioning grooves 16 for the second terminal set 3 to be embedded and clamped are arranged on the side wall and the top of the base 11; each terminal of the first terminal set 2 includes a first holding portion 21, a first contact portion 22 extending from the first holding portion 21 and exposed to the tongue portion 12, and a first soldering portion 23 extending from the first holding portion 21 and exposed to the insulating base 1, wherein the first contact portion 22 is a flat plate structure; the second terminal group 3, its whole shape is according to the curved design of surface outline of the insulating base 1, every terminal includes the second fixed department 31, extend from the second fixed department 31 and expose in the second contact portion 32 of the tongue 12, and extend from the second fixed department 31 the second welding part 33 of the insulating base 1, the second contact portion 32 is the elastic bending structure; and a shielding shell 4 coated outside the insulating base body 1.
