[embodiment]
As Fig. 4, Fig. 5, Figure 6 and Figure 7, the structure improved buckle of the utility model system is used for electric connector 4 is fixed in circuit board 5, and it includes a latch 1 and a plug part 3.Latch 1 comprises connecting portion 13 and is called accommodation space 12 from the space that connecting portion 13 extends between two elastic arms, 10, two elastic arms 10 downwards that these two elastic arms, 10 ends are respectively equipped with clamping part 11.Plug part 3 comprises one handle 35, to make things convenient for installing stopper spare 3 in the accommodation space 12 of latch 1.Upwards be provided with main part 321 from handle 35, be provided with between handle 35 and the main part 321 and prejudge place 33, this main part 321 roughly is wedge shape, and its terminal two ora terminalis extend to the same side and are provided with fastener 31.
During installation, earlier this latch 1 is fixed on the electric connector 4 by connecting portion 13, then latch is inserted the corresponding hole 41,51 of electric connector 4 and circuit board 5, this moment latch elastic arm 10 can inside deviation with respectively by hole 41,51, when clamping part 11 extend into circuit board 5 hole opposite sides, can open and electric connector 4 is fixed on the circuit board 5 at two elastic arms 10.Then, will fill in part 3 inserts in the accommodation space 12 from the bottom up.Because plug part main part 321 is wedge shape, insert so can guide this plug spare 3 preferably.Snap portion 31 on this plug spare 3 produces strain when entering hole 51, and these snap portion 31 meeting resiliences after passing hole 51, button ends the upper surface at circuit board 5, is fixed in the accommodation space 12 thereby will fill in part 3.Can roll over handle 35 at last.The thickness of this plug spare main part 321 can be a bit larger tham the width of accommodation space 12, thereby 1 liang of elastic arm 10 of latch is outwards opened, so that electric connector 4 more firmly is immobilizated on the circuit board 5.
The utility model buckle is because fill in the part main body section in accommodation space, make latch two elastic arms be difficult for inside deviation, and this plug spare is provided with the snap portion that can be held in the circuit board hole, difficult drop-off, thus can guarantee effectively that the electric connector secure is on circuit board.
Certainly, the utility model buckle also can adopt other similar structures, can only establish one as the snap portion of plug part, also can extend (as shown in Figure 8) to opposition side by terminal two ora terminalis of main part, or extend (as shown in Figure 9) by terminal two ora terminalis of main part to two ends.
Figure 10, Figure 11 shows that the 4th kind of execution mode of the utility model buckle, latch 6 in this buckle is integrally formed with electric connector 7, and only be provided with an elastic arm 61, form accommodation space 62 between this elastic arm 61 and the electric connector 7, this electric connector 7 is in the through hole (not drawing among the figure) that is installed on pedestal 8, equally, snap portion 91 in its plug part 9 also can insert in this accommodation space 62, and button terminates in pedestal 8 inner surfaces, thereby can avoid elastic arm 61 inside deviations and cause electric connector 7 to come off from pedestal through hole 81.
Certainly, those skilled in the art expect that easily this buckle is not limited to be applied in the occasion of electric connector and circuit board or electric connector and pedestal, also can be applicable to other many occasions, as the radiator holder being fixed on the circuit board or the like, just repeat no more here.
