Come the utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Printed circuit board (PCB) clamping structure described in the utility model, it can be assembled in printed circuit board (PCB) in the casing fast, and dual upper and lower, the left and right degree of freedom that limits printed circuit board (PCB), and does not have the misgivings of using for a long time and getting loose.
Shown in Fig. 1, described printed circuit board (PCB) clamping structure, it comprises a printed circuit board (PCB) 1, a casing 2 and a sleeve 3, in addition, also comprises a rotating part 4.Wherein, described printed circuit board (PCB) 1 is for being installed on the described casing 2, and described rotating part 4 is for being inserted in the sleeve 3; For being provided with a plurality of fixing holes 10, and this fixing hole 10 can be trivial trivial when casing 2 of printed circuit board (PCB) 1 prior art screw and decide as shown in FIG., to offer one respectively in these fixing hole 10 both sides and slot 11 in the hole on described printed circuit board (PCB) 1.Again, on the described casing 2 and its with the installing printed circuit board (PCB) 1 face be provided with buckling structure 20, this buckling structure 20 is for to arch upward from casing 2, and the both side edges that arches upward of this buckling structure 20 vertically extends outward a buckle ear 201 respectively certainly, and offers perforate 2011 on this buckle ear 201; In addition, shown in Fig. 2 and Fig. 5, also offer a trivial hole 202 in the central position of this buckling structure 20, and in this institute, riveted has a nut 5 on the described buckling structure 20 and on the reverse side of its direction that arches upward, and this nut 5 is in alignment with above-mentioned trivial hole 202.
Be hollow form in the described sleeve 3, as shown in Figure 3, and the position, both sides near sleeve 3 one end ends is respectively arranged with a grab 30, this grab 30 is with respect to above-mentioned buckle ear 201, during assembling, this grab 30 promptly is fixed in printed circuit board (PCB) 1 on the casing 2 in the perforate 2011 that is snapped in above-mentioned buckle ear 201, in addition, its other end end then is recessed into a ring-type inclined-plane 31.
Shown in Fig. 4, described rotating part 4 one ends place casing 2 for being inserted in the above-mentioned sleeve 3 and setting firmly, it comprises a body 40, and these body 40 1 ends are a lever 403 in the form of annular discs, but the user is by this this rotating part 4 of lever 403 left rotation and right rotation, then attacked one section screw thread 402 on the other end of this body 40, this section screw thread 402 can trivial the scheduling of spiral shell be riveting in the nut 5 of casing 2 after this end passes above-mentioned trivial hole 202 for making, thereby described rotating part 4 is fixing, an and then step printed circuit board (PCB) 1 is fixed on the casing 2 again.
In addition, on the body 40 of described rotating part 4 and be positioned at lever 403 ends and also also be arranged with a spring 406, and an end of this spring 406 is for being fixedly arranged on described lever 403, its other end and do not place sleeve 3 for ring-type inclined-plane 31 ends that place sleeve 3 just when rotating part 4 is inserted in the sleeve 3.On the body 40 of described rotating part 4, offer a perforation 404, so that rotating part 4 bodies are easily inserted in the sleeve 3 again; Refer again to shown in Fig. 4, and protrude respectively on this body 40 and in perforation position, 404 both sides certainly and be provided with a button piece 406, thereby also make when rotating part 4 is inserted in sleeve 3, this above-mentioned button piece 406 is snapped in the ring-type inclined-plane 31 of sleeve 3 in sleeve 3 time, and then makes described rotating part 4 can not deviate from from sleeve 3 easily.
In addition, shown in Fig. 5 and Fig. 6, during printed circuit board (PCB) 1, at first, it is on the base of cabinet casing 2 that printed circuit board (PCB) 1 is placed during assembling, and makes fluting 11 on it aim at and be sheathed on the buckle ear 201 on the base that is arranged at casing 2; Secondly, described sleeve 3 is placed between the described buckle ear 201, and this sleeve 3 of clinching makes the grab 30 on it be snapped in the perforate 2011 of offering on the buckle ear 201, at this moment, the end that right grab 30 ends are set of described sleeve 3 is for contacting at printed circuit board (PCB) 1, and promptly is buckled in printed circuit board (PCB) 1 in the cabinet admittedly; And then with described rotating part 4 in alignment with sleeve 3 and go into its clinching in the sleeve 3 and pass trivial hole 202 in nut 5, described spring 406 1 ends are for being fixedly arranged on lever 403, the other end then is the ring-type inclined-plane 40 that contacts in sleeve 3; Described button piece 405 and for being snapped in the sleeve 3, at this moment, described ring-type inclined-plane 40 is for being in spring and buckleing 405 of pieces; At last, rotate this rotating part 4 and make that its lower end snail is trivial to go in the nut 5, and it screws direction and is the hand of spiral along rotating part 4, equally, this rotating part 4 is also for being subject to this hand of spiral, again, shown in Fig. 6, and after rotating part 4 screws, be after printed circuit board (PCB) 1 is fixed on the base of cabinet casing 2, and on the cabinet that closes behind the lid 21, this loam cake 21 is for pressing the lever 403 that touches in described rotating part 4, thereby also give rotating part one pressure, and then prevent the problem that rotating part is loosening.
Shown in Fig. 7, by said structure and step, printed circuit board (PCB) clamping structure described in the utility model can at first be located by the buckling structure 20 that is arranged at casing 2, rely on the grab 30 of sleeve 3 to be snapped in the perforate 2011 of buckling structure 20 then and first that printed circuit board (PCB) 1 is fixing, at last, trivial promptly and once more that printed circuit board (PCB) 1 is fixing in the nut 5 that is riveting in buckling structure 20 by rotating part 4 spiral shells again, thereby prevented screw under the prior art from getting loose easily and caused the loosening problem of printed circuit board (PCB) 1 that this described printed circuit board (PCB) clamping structure can provide on the printed circuit board (PCB) 1, down, the restriction of a left side and right four orientation degrees of freedom.
In addition,, and only rotating part 4 need be unscrewed from nut 5, pull buckle ear 201 then and make the grab 30 with sleeve 3 from the perforate 2011 of buckle ear 201, break away from, sleeve 3 and rotating part 4 be extracted in the lump got final product at last if the user needs disassemble printed circuit board 1.
