[embodiment]

The utility model is described in further detail below in conjunction with drawings and Examples.

Shown in the 1st, 2 and 3 figure, in embodiment of the present utility model, micro connector is by an insulating base 1, most power springs 2 and accepts sheet 3 and constituted; Wherein, this insulating base 1 is rectangle, and has body part 10, the leading flank 13 of the upper surface 11 of body part 10, bottom surface 12, correspondence and the beside 14 of other two correspondences.Most depressed parts 15 are arranged in the bottom surface 12 of body part 10, the number of depressed part 15 is two in the present embodiment, respectively be provided with perforation 18 at each depressed part 15 center, each perforation 18 is a bellmouth, run through the depressed part 15 and upper surface 11 of insulating base bottom surface 12, have first aperture 181, second aperture 182 (shown in the 3rd figure).Be provided with for accepting the crack groove 16 that sheet 3 inserts at each perforation 18 two ends along depressed part 15, this crack groove 16 forms corner cut 17 with the limit end of depressed part 15, corner cut 17 is inclined surface, accepts the structure of sheet 3 with cooperation, make when accepting sheet 3 and inserting crack groove 16 can with insulating base 1 fluid-tight engagement; Insulating base 1 is located when mounted for convenience, and the leading flank 13 of body part 10 is provided with a recess 131, has formed the sloped sidewall 132 of recess correspondence thus; Leading flank 13 and another beside 14 formed handing-over angles of body part 10 are fillet 19.

Power spring 2 is inserted in the perforation 18 of insulating body 1; Shown in the 4th figure, power spring 2 is a conical design, by top contact bung flange 21, bottom bung flange 22, end coil 23 are formed, and this power spring 2 can be divided into two parts, and top contact bung flange 21 parts are Hookean spring, Lower Half bung flange 22 parts are the volute spring of convergent, it can be matched with the cone-type piercer 18 on the insulating base 1, and by the hole wall of the bung flange of spring and perforation 18 touch mutually to effect, make being set in the perforation 18 that power spring 2 can be firm.For making things convenient for the location when mounted, the diameter of bottom bung flange 22 is greater than the piercing aperture 182 of insulating base frame, the piercing aperture 181 that is equivalent to insulating base frame, so that when assembling power spring 2 be inserted in the perforation 18 of insulating base and coincide, and power spring 2 in assembling afterwards the one distal process for the perforation 18 of insulating base 1 as contact site.

Shown in the 5th figure, accept sheet 3 and have its loading end 30, extension 31 and perforation 32; Wherein, the width that extension 31 extends is slightly less than the width of loading end 30, and extension 31 is made up of the end 311 of stretching out, kink 312 and top ends 313, and the position is provided with corresponding hangnail 314 between its kink 312 and the top ends 313.In the present embodiment, accept sheet 3 and the time place the bottom of power spring 2 in assembling, its extension 31 inserts crack, the bottom surface groove 16 of insulating base 1, and the loading end 30 of accepting sheet 3 is fitted with the depressed part 15 of insulating base 1, interfere with each other fixing by the hangnail 314 of the extension 31 of accepting sheet 3 and the basal surface crack groove 16 of insulating base 1, if be fixed in the bottom of insulating body 1, and it is horizontal with the bottom surface 12 of insulating base 1 to accept the loading end 30 of sheet 3; The loading end 30 of accepting sheet 3 contacts conducting with power spring 2 bottom bung flanges 22, end coil 23, the most important design of the utility model is to be provided with perforation 32 at the loading end 30 of accepting sheet 3, the part that power spring 2 can be had an X-rayed from this hole in the assembling back, thus, when welding with associated circuit board, molten tin flows through welding on perforation 32 and the power spring 2, and the number of perforation 32 is one except that present embodiment, also can be most small diameter bore, can increase the effect that penetrates of molten tin.

It is not good that the utility model can improve the spring contact that existing product exists, and electrically transmits shortcomings such as bad.Structure of the present utility model can have different versions, can be variations such as any geometry such as variation on the number of holes and perforation shape.
