Embodiment
See also Fig. 1, in a preferred embodiments of the present invention, an electronic installation comprises a circuit board 10, a casing 100, a fixture 30, positioning piece 50 and a locking part 70.In one embodiment, said circuit board 10 can be a mainboard.
Please continue to consult Fig. 2, said casing 100 comprises a base plate 20, and said circuit board 10 is installed on the said base plate 20.Said base plate 20 is offered some locking holes 21, and offers a location hole 23 respectively in the both sides of said locking hole 21.In one embodiment, said locking hole 21 is round holes.
Said fixture 30 directly is fixed on said circuit board 10 through fixed forms such as riveted joint or welding.Said fixture 30 is provided with perforate 31, is provided with internal thread in the said perforate 31.In one embodiment, said fixture 30 is a cylinder, and said perforate 31 is circular.
Said keeper 50 comprises a support portion 51 and all right one way or the other elastically-deformable clamping part 53 in order to said circuit board 10 is fixed on the certain altitude.A through hole 511 is offered in said support portion 51, in order to accommodate said fixture 30.In one embodiment, said through hole 511 is a square opening.Said clamping part 53 extends to form downwards along said through hole 511 two opposite sides from said support portion 51.Distance between the adjacent edge of the location hole 23 that the minimum range between the two said clamping parts 53 is offered less than two said base plates 20, ultimate range is greater than the distance between the adjacent edge of two said location holes 23.Said clamping part 53 can be between a primary importance and a second place strain; When primary importance, said clamping part 53 penetrates said location hole 23, when the second place; Said clamping part 53 is buckled in the said location hole 23, thereby said circuit board 10 is fixed on the said base plate 20.Said circuit board 10 to the distance between the upper and lower surface of the distance of said base plate 20 and said support portion 51 about equally.
Said locking part 70 comprises a locking part 71 and an operating portion 73.The internal diameter of the diameter of the diameter of said locking part 71 and said locking hole 21, said fixture 30 about equally, and less than the diameter of said operating portion 73.Said locking part 71 is provided with external screw thread, in order to match with internal thread that said fixture 30 is offered.In one embodiment, the cross section of said locking part 70 is circular.
Please continue to consult Fig. 3-4, when said circuit board 10 is installed, earlier said keeper 50 is fixed on the lower surface of said circuit board 10.With the said fixture 30 of through hole 511 alignment that said keeper 50 is offered, said keeper 50 is moved near said circuit board 10 directions in the edge.Said fixture 30 passes said through hole 511, and the lower surface of the upper surface of said support portion 51 and said circuit board 10 leans.Utilize fixed form such as gluing that said keeper 50 is bonded on the said circuit board 10.Said fixture 30 is arranged in said keeper 50.Fixing then said circuit board 10 is with the location hole 23 of the said base plate 20 of clamping part 53 alignment of said keeper 50.Said circuit board 10 is moved said circuit board 10 along the direction near said base plate 20, and said clamping part 53 receives compressing around the said location hole 23 and produces inside elastic deformation.Said clamping part 53 penetrates said location hole 23, and stretches out said base plate 20, and the bottom surface of the upper surface of said base plate 20 and said support portion 51 leans.Said clamping part 53 elastic deformations are replied, and are stuck in the lower surface of said base plate 20.Thereby, said circuit board 10 is positioned on the said base plate 20.The locking hole 21 that the locking part 71 of said locking part 70 is passed through said base plate 20 screws in said fixture 30, leans up to the lower surface of said operating portion 73 with said base plate 20.Thereby, said circuit board 10 is locked together with said base plate 20.Said fixture 30 is electrically connected with said locking part 70, and said circuit board 10 is electrically connected with said base plate 20.
