Description
[technical field]
The utility model relates to a kind of electric connector.
[background technology]
Be used to electrically connect CPU in the prior art to the electric connector that docks on the substrate, the arrangement of the conducting terminal that uses in this kind electric connector is more and more tightr, so the structure to this kind electric connector has proposed more and more higher requirement, especially realize how electric connector and the butt joint substrate good welds aspect.
Be illustrated in figure 1 as an electric connector of commonly using, this electric connector comprises an insulating body 1 and is located in multi-conducting terminals 2 and tin ball 3 in this insulating body 1, this conducting terminal 2 has hook-shaped welding ends 25, this hook-shaped welding ends 25 props up this tin ball 3 Lower Halves, the most tin creams 4 of coating on the butt joint substrate 5, this welding ends 25 is soldered to described butt joint substrate 5 by this tin cream 4.
Aforesaid electric connector, because tin ball 3 is by hook-shaped welding ends 25 clampings of conducting terminal 2, when this electric connector being soldered on this butt joint substrate 5, under the certain situation of tin cream 4 thickness of coating, this tin cream 4 can only touch conducting terminal 2, and also can only clean to conducting terminal 2, cause the welding function of tin ball 3 not bring into play, therefore can influence welding quality.
Reduce welding sequence as desire, make tin cream 4 can contact simultaneously and can clean simultaneously with tin ball 3 with conducting terminal 2, to realize that conducting terminal 2 and tin ball 3 are soldered to butt joint substrate 5 simultaneously, then can exist following problem: the one, cause the situation of unnecessary waste tin cream 4; The 2nd, in the arrangement of butt joint on the substrate 5 more and more closely under the situation, the tin cream 4 of coating is too thick, causes the pollution of butt joint substrate 5 easily at conducting terminal 2.
Be illustrated in figure 2 as the electric connector that another is commonly used, this electric connector comprise an insulating body 1 ' and be located in this insulating body 1 ' in multi-conducting terminals 2 ' with tin ball 3 ', this conducting terminal 2 ' have tabular main body 21 ', do not have the hook part, this conducting terminal 2 ' bottom and tin ball 3 ' bottom centre position roughly are positioned at same horizontal plane, butt joint substrate 5 ' on be coated with most tin creams 4 ', this conducting terminal 2 ' bottom by tin cream 4 ' be soldered to butt joint substrate 5 '.
Aforesaid electric connector, coating tin cream 4 ' to docking substrate 5 ' when going up, conducting terminal 2 ' and tin ball 3 ' can touch simultaneously tin cream 4 ', therefore more easily realize conducting terminal 2 ' and 3 ' time of tin ball be soldered to butt joint substrate 5 ', but because this electric connector adopts tin ball 3 ' be resisted against such structure setting of tabular main body 21 ' side, make that the distance between conducting terminal 2 ' bottom and the tin ball 3 ' bottom centre position is bigger, thereby make to need the tin cream 4 ' width of coating bigger, therefore exist equally waste tin cream 4 ' situation.
Be illustrated in figure 3 as further improved electric connector, this electric connector comprises the multi-conducting terminals 2 " with tin ball 3 " in the insulating body 1 " and being located in this insulating body 1 ", this conducting terminal 2 " main body 21 " is provided with a hole, for tin ball 3 " part enter; butt joint substrate 5 " on be coated with most tin creams 4 ", this conducting terminal 3 " bottom is by tin cream 4 " is soldered to and docks substrate 5 ".
Aforesaid electric connector, electric connection between " part enter conducting terminal 2 " main body 21 because tin ball 3 " goes up in the hole that is provided with; the distance of tin ball 3 " bottom centre position and the conducting terminal 2 " bottom of having furthered thus; but because the contact area of conducting terminal 2 " with dock substrate 4 " is less; occur the solid phenomenon of not prison welding easily when therefore " being soldered to and docking substrate 4 " conducting terminal 2 upward, thereby influence electric connector and dock substrate 4 ".
In view of the foregoing, be necessary to design a kind of new electric connector, to overcome above-mentioned defective.
