Description
Technical field
The utility model relates to the electromechanical compo field, is meant a kind of female end of connector especially.
Background technology
As shown in Figure 1, connector comprises female end 1 and male end 2.Connector female end 1 comprises: plastic cement part 3 and at least one terminal 4.Female end terminal 4 is divided into three parts from function: be out of shape pin 11, wiring board pin 12, reach support structure body 13.
When male end 2 cooperated with female end 1, the male end contact pin inserted female end terminal 4.Fig. 1 is the cutaway view before and after the male end 2 of connector in the prior art cooperates with female end 1.After the male end contact pin inserts female end terminal 4, the contact site 111 of female end terminal 4 contacts with the contact site of male end contact pin, the contact site 111 of female end terminal 4 is coated with metal, and the contact site of male end contact pin is coated with metal, thereby realizes being electrically connected of female end terminal 4 and male end contact pin.Described contact site 111 has the contact-making surface 1111 that contacts with the male end contact pin, and the side view of contact-making surface is generally: one section circular arc.
Have contact position between described contact site 111 and the described male end contact pin, the end view of contact position is the contact, and with before female end cooperates, the contact is A in male end 2
1, contact A
1 Support structure body 13 to female end terminal 4 has certain distance.
As shown in Figure 2, be the geometry analysis diagrams of the end view of the contact-making surface of the female end terminal that contact with the male end contact pin in the existing connector.Please in conjunction with Fig. 1 and Fig. 2, the left side of Fig. 1 is the schematic diagram before male end and female end cooperates, and the right of Fig. 1 is the schematic diagram after male end and female end cooperates.
When the male end contact pin inserted female end terminal 4, the contact position on female end termination contact portion 111 and the contact-making surface 1111 that the male end contact pin contacts can be offset along with the insertion of male end contact pin with respect to the position of female end terminal structure supporting body 13, and reason is as follows:
When the male end contact pin inserted female end terminal 4, the distortion pin 11 of female end terminal was offset, and this skew is the center of circle with the tie point G of distortion pin 11 and support structure body 13, the center of circle O that justifies with the circular arc place of the contact-making surface 1111 of contact site 111
1Distance to the tie point G that is out of shape pin 11 and support structure body 13 is a radius, and deviation angle is a.Since distortion pin 11 skews of female end terminal 4, and the contact position that cooperates on the preceding female end termination contact face 1111 that contacts with the male end contact pin is raise.The locational contact of female end termination contact was A before the male end contact pin cooperated with female end terminal 4
1, the male end contact pin cooperates the locational contact of female end termination contact, back with female end terminal 4 be B
1Point, the contact A on the contact position before cooperating
1Point moves to new position after cooperation, after the cooperation, the contact position on the female end termination contact face 1111 that contacts with the male end contact pin descends, and the contact on the contact position after the cooperation drops to B
1The point.Because the radius of curvature of the circular arc of female end termination contact face 1111 is bigger, new contact B
1Shorter in the distance that the vertical direction of female end termination contact face 1111 descends, can't offset the new contact B that the integral body of the circular arc place circle of female end terminal raises and causes
1The position raises, the new contact B after the cooperation
1Though the some position is lower than A
1, but with the skew before former contact A
1The place horizontal line is compared, and has still exceeded Δ h in vertical direction.
Before cooperating for connector male and female end and after cooperating, the not high occasion of female end termination contact position accuracy demand, the contact position skew can not influence the function that is electrically connected of male end contact pin and female end terminal.But along with the trend development of electronic equipment to miniaturization, the volume of connector is also more and more littler, for high-accuracy miniature connector, for example for memory bar, video card etc. with the card insert type connector of printed-circuit connector as the male end contact pin, the contact site limited length of male end contact pin, the skew of contact position may cause female end termination contact position to move to the outer insulating regions of male end contact pin contact site, and can't finish the electrical connection function.
