Embodiment
Followingly describe the preferred embodiments of the present invention in detail with reference to Fig. 2 to Fig. 6:
The fixture of circuit board of the present invention mainly comprises erection column 28, holding device 32 and retaining device 34.In the fixture preferred embodiment of circuit board of the present invention shown in Figure 2, circuit board 24 is provided with a plurality of through holes 30, the circuit layout of the visual circuit board 24 of the quantity of through hole 30 and allocation position and suitably the decision.One end of the erection column 28 that metal material is made just can insert through hole 30, and is that (surface mount technology SMT) is welded and fixed to it on circuit board 24 by surface mounting technology.This kind SMT welding process is extremely short required man-hour, can reduce the time and the cost of assembling.Holding device 32 is to form via the bottom surface of stamped metal housing 26.Retaining device 34 is the bottom surface that is arranged at housing 26 sides near opening, and it can utilize for example spot welding, lock or other modes are fixed to housing 26.
Fig. 3 is the amplification stereogram of erection column 28 of the present invention and holding device 32.Erection column 28 is slightly cylindrical haply, is provided with a groove 281 around it, and can supply to insert the through hole 30 on the circuit board 24 on it, and is soldered to the lower surface of circuit board 24.In addition, but the core tapping of erection column 28 and form a screw 282.Holding device 32 is the bottom surfaces that protrude from housing 36, which is provided with a long and narrow hole 321, and an end of long and narrow hole 321 is open into opening 332.The width of opening 332 is slightly larger than erection column 28 and the width of long and narrow hole just can match with the groove 281 of erection column 28.So, erection column 28 can slip into the holding device 32 by 322 ends towards horizontal direction from opening, and groove 281 is sticked in the long and narrow hole 321.Therefore, the circuit board that is fixed together with erection column 28 can insert and be fixed on the housing 26 towards horizontal direction.Fig. 4 is the sectional view of erection column 28 when being snapped into holding device 32.Because erection column 28 is provided with screw 282, therefore, can have more several installing holes on the circuit board 24 for other elements of installing, the space on the circuit board 24 can fully be utilized.
After circuit board 24 inserts housing 26, skid off by the opening 322 of holding device 32 accidentally in order to prevent erection column 28, the present invention is provided with at least one retaining device 34 in the side near opening, in order to stop moving of circuit board 24.With reference to shown in Figure 5, retaining device 34 is to be coated on the interior spring 343 of shell by a shell 341,, and a motion bar 342 is formed.One end of motion bar 342 is provided with a flange portion, and this flange portion is coated in the shell 341, and is held by this spring 343.By this, when not forcing in motion bar 341, motion bar 341 is to be in a higher primary importance, to be used to stopping circuit board 24, prevents that it from skidding off accidentally; When bestowing a downforce in motion bar 341,341 of motion bars move to a lower second place, and will no longer stop circuit board 24 this moment, thereby the user can optionally insert or extracting circuit plate 24 towards horizontal direction.
Fig. 6 is the stereogram of another embodiment of holding device of the present invention.The holding device 32 of this embodiment ' also form by stamped metal housing 26, the holding device 32 of its primary structure and Fig. 3 is similar, also have a long and narrow hole 321 ' and an opening 322 ' the present invention not only simplified the fixture of circuit board, make the plug of circuit board more quick and convenient, and, because housing 26, holding device 32 and erection column 28 all are to be made by metal material, therefore circuit board 24 can electrically be grounded to metal shell 26 via erection column 28 and holding device 32, effectively reaches the effect that prevents EMT.
Though the present invention is illustrated with reference to preferred embodiment and accompanying drawing, yet above-mentioned explanation should be considered as illustrative and non-limiting, variation and modification that those skilled in the art makes according to spirit of the present invention all should belong to protection scope of the present invention.
