[embodiment]
See also Fig. 4, electric connector of the present utility model includes: an insulating base frame 40, most the first terminals 60, the second most terminals 65, wherein:
This insulating base frame 40, be to be provided with a link slot 41 to use the grafting circuit board, the upper limb of this link slot 41 is formed with first 42 and second 43 of level of inclination from outside to inside, lower edge then is formed with the 3rd 44 and one fourth face 45 that cooperates first 42 inclination of a level from outside to inside, this link slot inner terminal is formed with one vertical the 5th 46, the 5th 46 and second 43 are provided with one and move back card inclined-plane 47, and this moves back card inclined-plane 47 and is provided with one vertical the 6th 48 with second 43; The upper limb of this link slot 11 is to be spaced first distance piece 49, use to form most spaced the first terminal loose slots 50, and lower edge is to be spaced second distance piece 51, uses to form most spaced second terminal loose slots 52.
This most the first terminal 60 is to be located at this insulating base frame 40, and it is provided with a flexible contact site 61, and this contact site 61 can be done springing in this first terminal loose slot 50, and it is provided with contact 62 this second 43 of protrusion of protrusion and is positioned at link slot 41.
The second most terminals 65 is to be located at this insulating base frame 40, and it is provided with a flexible contact site 66, and this contact site 66 can be done springing in this second terminal loose slot 52, and it is provided with contact 67 the 3rd 44 of protrusion of protrusion and is positioned at link slot 41.
By above structure, see also Fig. 5, circuit board 1 is worked as along first 42 oblique insertion link slot 41, this moment, the A point of circuit board top 2 contacted with the contact 62 of the first terminal 60, and 3 C point contacts with the contact 67 of second terminal 65 below the circuit board, the preceding part that circuit board top 2 like this is ordered at A all has and the first terminal 62 frictions, uses and scrapes removing oxide layer; Below the same circuit board all there being and 65 frictions of second terminal 3 preceding parts of ordering at C, uses and scrape removing oxide layer.
See also Fig. 6, when circuit board 1 depress change flat and first and second terminal 60,65 one-tenths when being electrically connected, this circuit board 1 front end can move back 47 commentaries on classics of card inclined-plane along this and put down, and makes 2, the 3 difference closings of circuit board above and below in second 43, the 3rd 44; Because circuit board 1 moves back the card inclined-plane 47 translation distance S that falls back by this, originally circuit board top 2 will retreat with contact 62 and be connected, it is bigger to add translation distance S backway this moment, and tie point is that the E point is far away at A point front end, so partly be electrically connected for scraping removing oxide layer; Though 3 then originally can be to advance and are connected with contact 67 below the circuit board, the right translation distance S that falls back because of circuit board 1 is big than forward travel distance, so the time tie point be F point in C point the place ahead.
