Embodiment

For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, cited below particularlyly go out preferred embodiment, and conjunction with figs. is described in detail below:

Please refer to Fig. 3, Fig. 4, Fig. 5, the preferred embodiment that it illustrates the utility model electric connector is assembled in the electronic product enclosure, comprises an insulation shell 2, has storage tank 21 on it; Conductive connecting piece 1 is arranged in the storage tank 21, and by storage tank 21 and stretch in outside the insulation shell 2, and is vertical substantially with self-contained circuit board 3, and supports with 3 one-tenth elastic top of circuit board and to electrically contact.

Please refer to Fig. 6, described conductive connecting piece 1 comprises into a single integrated structure contact chip 11, fixed part 12, flexible adjustment portion 13, elasticity arm 14, contact site 15;
