Description
[technical field]
The utility model relates to a kind of electric connector, is meant a kind of electric connector of connecting circuit plate especially.
[background technology]
See also Fig. 1, be to be a kind of known electric connector, it includes: an insulating base frame 10, be to be provided with a link slot 11 to use grafting circuit board 1, this link slot 11 is formed with first 12 and second 13 of level of inclination from outside to inside, lower edge then is formed with the 3rd 14 and one fourth face 15 that cooperates first 12 inclination of a level from outside to inside, this link slot inner terminal is formed with one vertical the 5th 16, and the upper limb of link slot 11 is to be spaced first distance piece 17, use and form most spaced the first terminal loose slots 18, and lower edge is to be spaced second distance piece 19, uses to form most spaced second terminal loose slots 20.
Most the first terminals 25 is to be located at this insulating base frame 10, and it is provided with a flexible contact site 26, and this contact site 26 can be done springing in this first terminal loose slot 18, and it is provided with contact 27 this second 13 of protrusion of protrusion and is positioned at link slot 11.
The second most terminals 30 is to be located at this insulating base frame 10, and it is provided with a flexible contact site 31, and this contact site 31 can be done springing in this second terminal loose slot 20, and it is provided with contact 32 the 3rd 14 of protrusion of protrusion and is positioned at link slot 11.
By above structure, see also Fig. 2, circuit board 1 can be along first 12 oblique insertion link slot 11, this moment circuit board 1 can back down the contact 32 of the contact 27 of this first terminal 25 and second terminal 30 and oblique cutting to the inner of link slot 11, so the contact (golden finger) on the two sides of circuit board 1 can rub with the first terminal 25 and second terminal 30 respectively, uses and scrapes removing oxide layer.
