Abstract
The utility model discloses an electric connector, which is installed on a circuit board and comprises an isolation body and a plurality of conductive terminals contained in the isolation body. The bottom of the isolation body is provided with a pair of positioning columns which is downwardly extended in the circuit board, wherein, a first positioning column is respectively and convexly provided with holding ribs which are horizontally extended around; the second position column is convexly provided with holding ribs fitted with the circuit board with interference along the vertical direction of the connecting line of the first position column and the second position column and is not convexly provided with holding ribs fitted with the circuit board with interference along the direction of the connecting line of the first position column and the second position column. This electric connector adopting this positioning column structure can be tight and firmly installed on the circuit board with high fit tolerance.
Description
[technical field]
The utility model is relevant a kind of electric connector, refers to a kind of electric connector that is installed on the circuit board especially.
[background technology]
As shown in Figures 1 and 2, existing in the industry two kinds of methods can be installed on electric connector on the circuit board.Wherein a kind of method is reference column 17 ' to be set and to establish installing hole 40 ' on circuit board 4 ' in the insulating body 10 ' bottom of electric connector 1 ', and installing hole 40 ' and electric connector 1 ' is fixing is inserted in reference column 17 ' interference.Often use and the electric connector 1 of plug repeatedly for needs ", in order to make reference column 17 " with circuit board 4 " installing hole 40 " cooperate tight more so that stronger grabbing plate force to be provided, can be at each reference column 17 " on be convexly equipped with four fixing flanks 170 ".
Reference column cooperates with installing hole more closely, and stress is stronger therebetween, and quality of fit requirement therebetween is also higher, otherwise, as cooperating inexact words, both just may occur destroying.Yet, improve the lifting that the accuracy of manufacture means manufacturing cost, particularly various components and parts being installed in the process of circuit board always needs heating, and low fit tolerance is difficult to be realized.
In sum, necessary existing electric connector is improved, to overcome aforementioned disadvantages of the prior art.
[utility model content]
The purpose of this utility model is to provide a kind of electric connector, and it can be under higher fit tolerance condition, being installed on the circuit board of close and firm.
For achieving the above object, the utility model adopts following technical scheme: a kind of electric connector, it is installed on the circuit board and comprises insulating body and be contained in the interior plurality of conductive terminals of insulating body.Described insulating body bottom is provided with first and second reference column that extends down into circuit board, first reference column convexes with the fixing flank to all round the horizon respectively, and second reference column is along the fixing flank that is not convexly equipped with on the line direction of itself and first reference column with the circuit board interference engagement.
The utility model also can adopt following technical scheme: a kind of electric coupler component, it comprises electric connector and circuit board, described electric connector comprises insulating body and is contained in the some second square conducting terminals in the insulating body and is covered in the outer shielding casing of insulating body, described insulating body bottom is provided with first and second reference column, circuit board is provided with installing hole, reference column extends in the installing hole, described first reference column convexes with in the fixing flank of all round the horizon and installing hole inwall interference engagement, and second reference column only is not convexly equipped with the fixing flank along first reference column and the second reference column line direction and installing hole inwall interference engagement.
Compared with prior art, the utlity model has following beneficial effect: respectively to around convex with the fixing flank first reference column electric connector is positioned on the circuit board and not removable, further locate electric connector to forward and backward second reference column that convexes with the fixing flank respectively and make it not rotatable, simultaneously, the second reference column left and right sides be not provided with the fixing flank and needn't with the circuit board interference engagement, it can be under higher fit tolerance condition, being installed on the circuit board of close and firm.

[embodiment]
See also Fig. 3 to shown in Figure 6, the utility model electric connector 1 comprises insulating body 10, plurality of conductive terminals 20 and shielding casing 30.
Conducting terminal 20 is a square, is contained in the terminal accommodating passage 14 corresponding in the insulating body 10.Shielding casing 30 is covered in outside the base portion 11 and hyoplastron 12 of insulating body 10, which is provided with the fixing pin 32 that extends into the some shell fragments 31 in the shielding casing 30 and extend into circuit board 4.
Please further consult Fig. 7 and shown in Figure 8, when electric connector 1 is installed on circuit board 4, fixing flank 170 in the tight interference engagement of inwall of first reference column, 17 all round the horizon and circuit board 4 installing holes 40 so that electric connector 1 is not removable, fixing flank 180 in the tight interference engagement of inwall of the front and back of second reference column 18 and circuit board 4 installing holes 40 so that electric connector 1 is rotatable.Simultaneously, second reference column 18 is along not being convexly equipped with the fixing flank on the line direction of itself and first reference column 17 and needn't be in the tight interference engagement of inwall of reference column 17,18 (or installing hole 40) line direction and installing hole 40, even in reference column 17,18 (or installing hole 40) line direction higher fit tolerance is arranged between reference column 18 and the installing hole 40, what electric connector 1 still can close and firm is installed on the circuit board 4.
