Fig. 2 is the stereogram that the utlity model has the electric connector of device for fastening;

Fig. 3 A is the stereogram that the utlity model has the electric connector of device for fastening, a sub-circuit board that is loaded with electronic component is shown inserts the state of not fixed by device for fastening behind this electric connector;

Fig. 3 B is the stereogram that the utlity model has the electric connector of device for fastening, and the state that described sub-circuit board has been fixed by device for fastening is shown.

The utility model electric connector 10 as shown in Figure 2 is used to be electrically connected electronic installation, and a sub-circuit board 20 as shown in Figure 3A and a female circuit board (not shown) are so that signal transmits between this sub-circuit board 20 and female circuit board.Aforementioned electric connector 10 comprises insulating body 100, terminal 200 and device for fastening 300, wherein this microscler insulating body 100 has a long and narrow accepting groove 102, contiguous these accepting groove 102 madial wall places, form a plurality of terminal tanks 104, accommodate relevant terminal 200 in this terminal tank 104, and the part of this terminal 200 extends in the aforesaid accepting groove 102.Aforesaid a pair of device for fastening 300 is respectively adjacent to the two relative ends that insulating body 100 is received dead slot 102, wherein each device for fastening 300 has: first main body 310, it is an elasticity support arm structure, one end and insulating body 100 one-body molded making, another relative free end extends upward, form a deflection releasing portion 312, and which is provided with a plurality of lobe structures, make things convenient for the user to use manual manipulation.In addition, below aforementioned releasing portion 312, a block clamping part 314 is arranged, it simultaneously is polygon inclined-plane 3142, the plate face of relative and vertical this first main body 310 in another buckle face 3144 and aforementioned polygon inclined-plane 3142.

Second main body 320, near described first main body 310, the integrally formed guidance part 324 of one side extends towards described accepting groove 102, make this guidance part 324 be positioned at aforementioned clamping part 314 belows, wherein these guidance part 324 upper surfaces and left-hand face respectively form a side cut plane 3244, and a conical surface 3246 and a cambered surface 3248 connect the side cut plane of described upper surface and left-hand face, the width of the wherein said conical surface 3246 is free powder ends that the narrowest place is positioned at guidance part 324, its width the widest part is connected with an end of this cambered surface 3248, these cambered surface 3248 another opposite ends and second main body, 320 one-body molded making.Aforementioned second main body 320 also has a stop section 322, one end and one-body molded the making of these second main body, 320 1 sides, another relative free end extends with identical bearing of trend from aforementioned guidance part 324, contiguous aforementioned first main body 310 rears, and perpendicular to the bearing of trend of this first main body 310.

When a sub-circuit board 20 inserts in the accepting groove 102 of aforementioned electric connector 10 insulating bodies 100 as shown in Figure 3A, this sub-circuit board 20 is not detained by aforementioned device for fastening 300 and is held, and the weld pad (not shown) that is positioned at these sub-circuit board 20 root edge surfaces also fully and terminal electrically reach Mechanical Contact.At this moment, if with sub-circuit board 20 root edges that insert is fulcrum, major axis around this insulating body 100 rotates, can make these sub-circuit board 20 two opposite sides edge 24 respectively near the device for fastening 300 at electric connector two ends, wherein each lateral margin 24 of this sub-circuit board 20 can contact the polygon inclined-plane 3142 of first main body, 310 clamping parts 314 earlier, and can be rotated further along this polygon inclined-plane 3142; The guidance part 324 of these device for fastening 300 second main bodys 320 can penetrate the semilune breach 22 on the sub-circuit board 20 two opposite sides edge 24 simultaneously, the conical surface 3246 bootable this sub-circuit board 20 to the clamping parts 314 of this guidance part 324 can be detained the button of holding and hold on the position (being buckle face 3144), and, can avoid this guidance part 324 to penetrate in the process of this breach 22 clamping stagnation takes place because of two side cut planes 3242 such as guidance part 324 upper surfaces and left-hand face exist.When the lateral margin 24 of aforementioned this sub-circuit board 20 rotates along this polygon inclined-plane; This lateral margin 24 can push first main body 310 deflection bending outside insulating body 100 of electric connector 10 both sides, make these sub-circuit board 20 lateral margins enter the buckle face 3144 of this clamping part 314 smoothly, the breach 24 of this sub-circuit board 20 is also just in time detained by the cambered surface 3246 of this guidance part 324 (shown in Fig. 3 B) and is held simultaneously, can limit moving of these sub-circuit board 20 horizontal directions and vertical direction by this simultaneously, and the weld pad (not shown) of aforementioned sub-circuit board 20 root edges can electrically reach machinery reliably and press electric shock connector 10 terminals 200, and its result is shown in Fig. 3 B.When the button of wanting to remove 10 pairs of sub-circuit boards 20 of electric connector is held, the user can be with hand to pressing down the releasing portion 312 that touches first main body, 310 ends, make the outwards deflection bending once again of this first main body 310, wherein for avoiding excessive this first main body, the 310 permanent bendings that cause of exerting oneself, the excessive deflection of this first main body 310 can be blocked in second main body, 320 stop sections 322 that are positioned at these first main body, 310 rears, and because of this stop section 322 has the shorter arm of force, so can bear bigger flexure stress.Aforementioned these first main body, 310 outside deflections are to a certain degree the time, and this sub-circuit board 20 can oppositely return to initial conditions as shown in Figure 3A because of the bounce effect of electric connector 20 terminals 200.Be noted that it is a lot of that the clamping part 314 of aforementioned this first main body 310 is higher than second main body 320, can withhold the corner of sub-circuit board 20, make its unlikely printed circuit (not shown) that is snapped into sub-circuit board 20 lateral margins 24 and this printed circuit of crushing.

Be noted that in the present embodiment, this guidance part 324 that is arranged on second main body 320 also can be arranged on first main body 310, and identical effect can be provided.
