Fig. 3 is the utility model electric connector first embodiment stereogram;

Fig. 4 is installed in the cutaway view of circuit board for electric connector among Fig. 3;

Fig. 5 is the utility model electric connector second embodiment stereogram;

Fig. 6 is installed in the cutaway view of circuit board for electric connector among Fig. 5.

Please consult Fig. 3 and Fig. 4 simultaneously, it is the utility model electric connector first embodiment stereogram, and this electric connector is installed in the cutaway view of circuit board.Wherein this electric connector 20 comprises a microscler insulation shell 21, two row are along the terminal channel 22 of insulation shell 21 vertical symmetrical deployings, one insulate housing outward extending first reference column 23 of 21 vertical end one and certainly from insulating outward extending second reference column 24 of housing 21 vertical other end one, this terminal channel 22 is accommodated corresponding several Zhi Duanzi (not shown) in wherein, this first reference column 23 is vertical mutually on integrally-built deploying direction with second reference column 24, i.e. parallel longitudinal with insulation shell 21, another is vertical vertical with insulation shell 21 then, and both composition structures are identical.

The section that this first reference column 23 (second reference column 24) is parallel to circuit board 1 (see figure 4) that slightly assumes diamond in shape, comprise first spacer 25 and second spacer 26 that are positioned at two ends, and a retaining piece 27 in the middle of being positioned at, and between first spacer 25 and retaining piece 27, form one first fluting 28, between the retaining piece 27 and second spacer 26, form one second fluting 29.When first reference column 23 of electric connector 20 was installed in the location hole corresponding on the circuit board 12 with second reference column 24, this first fluting 28 and second slotted 29 respectively as the space of first spacer 25 and second spacer, 26 strains.

Because the section of this first reference column 23 and second reference column 24 slightly assumes diamond in shape, so inner edge maintenance one distance of location hole 2 is the gap of a respectively on the both sides of this retaining piece 27 and the circuit board 1.Because the cause of this gap a, the both sides of this first reference column 23 insulation shell 21 vertically on have a nargin (tolerance) with the inner edge of this location hole 2 respectively, there is nargin perpendicular to insulation shell 21 in this integrally-built deploying direction second reference column 24 vertical with first reference column 23 on vertically, this kind while insulation shell 21 vertically on perpendicular to the structure that nargin is vertically all arranged, to significantly increase the convenience of installing electric connector 20 when the circuit board 1, and cause first spacer 25 (second spacer 26) to be out of shape excessive the fracture because of off normal slightly can avoid installing electric connector 20 time.In addition, be appreciated that, this first reference column 23 not necessarily needs to be perpendicular to one another on integrally-built deploying direction with second reference column 24, just can reach above-mentioned effect, as long as this first reference column 23 and second reference column 24, the relation that is an angle on overall structure deploying direction makes both deploying direction not parallel or not during conllinear, also can reach above-mentioned effect.
