Embodiment
For the clear structure of the present utility model of your auditor is formed, and the overall operation mode, cooperate graphic being described as follows now:
The shell fragment fixture construction of the utility model electric device, the basic structure of its whole shell fragment is formed as shown in Figures 2 and 3, be to be bent to form respectively and casing (figure slightly) contact site 11 that contacts and the weld part 12 that combines with circuit board 20 equally by metal sheet (copper sheet) one, other has an extension 13 to be linked between contact site 11 and the weld part 12, make whole shell fragment 10 become the structure kenel that contact site 11 is provided in top, weld part 12 zone, and make contact site 11 have normality maintenance elastic reaction up.
Wherein, shell fragment 10 is that the joining place at weld part 12 and extension 13 is bent to form a recess 14, this recess 14 is both to have take the altitude so that the plate body of power circuit board 20 stretches into, and constitutes the conjugation that the extension 13 that makes shell fragment 10 and weld part 12 are compressed on the upper and lower plate face of circuit board 20 respectively; Please cooperate three simultaneously according to Fig. 3 and shown in Figure 4, basically its circuit board 20 only need be provided with a through hole 21 in order to perfusion scolder 30 at least at the weld part 12 applying positions that correspond to shell fragment 10, when shell fragment 10 combines with circuit board 20, constitute mechanical clasps by recess with engaging of circuit board plate body and hold effect, and the scolder 30 that pours into tin cream and so at through hole 21 places of circuit board 20, constitute sticking together of shell fragment and circuit board by scolder, can constitute and effectively avoid shell fragment 10 displacements, the fixture construction that comes off, allow shell fragment 10 produce under the situation of distortion bearing casing 40 compressings, still firm is connected together with circuit board 20, and is unlikely perk or gets loose, drop.
In the present embodiment, circuit board 20 is further to be provided with at least one at its corresponding position periphery of fitting with shell fragment 10 weld parts 12 to run through groove 22, please cooperate three simultaneously according to shown in Figure 5, but this runs through recess 14 (weld part 12 positions of recess 14 lower ends as shown in the figure, the position of an end wherein that groove 22 is ammunition feed sheets 10, or the extension of recess upper end and the position of contact site) pass, allow shell fragment 10 be configured in both allocations of circuit board 20 inside, and shell fragment 10 is provided with the protuberance 15 that can correspondingly buckle into through hole 21 at the set/vertically-arranged of its weld part 10, when the plate body of circuit board 20 stretches into shell fragment 10 recesses 14, can produce the effect of shell fragment 10 with circuit board 20 location.
Moreover, shell fragment 10 in the utility model is that the tail end at its contact site 11 is bent into first invayination 16 that slightly is upturned, as shown in Figure 4, at casing 40 during towards shell fragment 10 compressing, can produce the supplemental support effect by invayination 16, and disperse shell fragment 10 diastrophic stresses, to increase the reliability of shell fragment 10; Certainly, shell fragment 10 also can be bent into second invayination 17 of a perk slightly downwards at the tail end of its weld part 12, second invayination 17 produces the lead angle effect thus, and aforesaid protuberance 15 is designed to the configuration of tiltedly stretching towards inside by recess 14 openings, so that the plate body of circuit board 20 stretches into recess 14, and when protuberance 15 enters through hole 21.Under the elastic reaction of shell fragment 10, can produce clear and definite buckle sense of touch sound even, allow assembler know that shell fragment 10 combines with circuit board 20 really.
As mentioned above, the utility model provides electric device a kind of preferable feasible shell fragment fixture construction, so offer the application of novel patent in accordance with the law; Yet, above implementation and graphic shown in, be this creation preferred embodiment, be not to limit to this creation with this, be with, with approximate, identical person such as the structure of this creation, device, feature, all should belong to founding within purpose and the claim of this creation such as.
