Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Referring to Fig. 1 and Fig. 2, the utility model embodiment provides a kind of electroconductive elastic sheet, comprise base portion 1, elastic arm 2 and first bending part 3, described elastic arm 2 one ends are connected with an end of described base portion 1 by described first bending part 3, and described elastic arm 2 is positioned at described base portion 1 top and forms a gap with described base portion 1; Described base portion 1 both sides vertically are provided with the baffle plate 4 that is positioned at described elastic arm 2 both sides respectively, described baffle plate 4 is provided with the hooked scarf 41 that is pressed on the described elastic arm 2, described elastic arm 2 has the linkage section 21 that is connected with described first bending part 3, be used for and the contact-segment 22 of external circuitry contact and second bending part 23 that is connected this linkage section 21 and contact-segment 22, described contact-segment 22 forms opening obtuse angle outwardly with described linkage section 21, the linkage section 21 of described elastic arm 2 is parallel with described base portion 1, and described hooked scarf 41 is pressed on the linkage section 21 of described elastic arm 2.Elastic arm 2 is subjected to when the pressure of base portion 1, being rotating fulcrum with first bending part 3 draws close to base portion 1 compression, strain takes place in first bending part 3 thereupon, when second bending part 23 of elastic arm 2 touches base portion 1 surperficial, its linkage section 21 no longer rotates around first bending part 3, then, the contact-segment 22 of elastic arm 2 is that rotating fulcrum is further drawn close to base portion 1 compression with second bending part 23, and strain takes place second bending part 23.If remove the pressure that puts on the elastic arm 2, the elastic force that second bending part 23 and first bending part 3 can provide elastic arm 2 to reset.Elastic arm 2 has two stress deformation points (i.e. first bending part 3 and second bending part 23) in compressive state, the elastic arm 2 of the compressive state internal stress of bearing just is distributed on two above-mentioned stress deformation points like this, tradition has only the electroconductive elastic sheet of a stress deformation point more can bear repeatedly elastic compression and be difficult for causing plastic deformation, and longer service life, elastic effect are better.Simultaneously, second bending part 23 is positioned at the middle part of elastic arm 2, second bending part 23 can be used as the rotation compression fulcrum of elastic arm contact-segment 22, can make elastic arm 2 more press close to base portion 1, and the electroconductive elastic sheet that the utility model provides can be used between the spacing littler circuit board or electronic component.And for tradition have only the electroconductive elastic sheet of a stress deformation point, elastic arm be subjected to very short-range compression after its top will touch base portion, and can not be used between the spacing less circuit board or electronic component.The working depth (even time spent elastic arm top is to distance of base portion lower surface) of existing electroconductive elastic sheet is all more than 1mm, and the length of shell fragment will be accomplished more than the 3.3mm, and the working depth of electroconductive elastic sheet provided by the utility model can be in 0.5mm, and the length of shell fragment can be manufactured in the 2.8mm.Certainly, the shell fragment of making for metal material all can have an elastic limit, be that compressive deformation surpasses certain limit and can cause plastic deformation, cause shell fragment to reset, the baffle plate 4 that is positioned at elastic arm 2 both sides can prevent effectively that electroconductive elastic sheet from too being exerted pressure by exterior object (for example circuit board or electronic component) and cause plastic deformation.The height of baffle plate 4 if guarantee elastic arm 2 be compressed in elastic limit with interior, the object of exerting pressure to electroconductive elastic sheet is replaced baffle plate 4 backs and just can not be continued to press elastic arm 2, plays the effect of protecting the electroconductive elastic sheet reset function.And the hooked scarf 41 on the baffle plate 4 can provide precompression to elastic arm 2, guarantee that elastic arm 2 is before use all on sustained height, plastic deformations take place in first bending part 3 in the time of can preventing also that elastic arm 2 accidents are subjected to the power of outwards turnover, destroy elasticity and the original height of electroconductive elastic sheet.Referring to Fig. 3, the utility model can be welded in down earlier on the circuit board 6 in use, going up circuit board 5 then is pressed on the utility model, elastic arm 2 obtains compression, the bounce that its contact-segment 22 dependence second bending part 23 provides is to raising up and replacing with last circuit board 5, at this moment, electroconductive elastic sheet just plays the effect of the upper and lower circuit board that electrically conducts.
Referring to Fig. 1, the end that the linkage section 21 of described elastic arm 2 is connected with described first bending part 3 to the width of the end that this linkage section 21 is connected with described second bending part 23 outwards is gradual dwindling (namely being narrowed down by wide).The external force that is made progress improperly when elastic arm 2 because linkage section 21 is narrower than the width of base portion 1, can plays and alleviate the internal stress that deformation brings, the excessive and phenomenon that fractures of the internal stress that effectively prevents first bending part 3.
Referring to Fig. 1, the end that the contact-segment 22 of described elastic arm 2 is connected with described second bending part 23 to the width on top is gradual to be dwindled.The external force that is made progress improperly when elastic arm 2 because contact-segment 22 is narrower than the width of linkage section 21, can plays and alleviate the internal stress that deformation brings, the excessive and phenomenon that fractures of the internal stress that effectively prevents second bending part 23.
Particularly, contact-segment 22 tops of described elastic arm 2 have the 3rd bending part 221 of inside bending, the arcuate structure of bending can guarantee no matter elastic arm 2 is in any working depth, its top can be replaced circuit board or the electronic component that is pressed on the elastic arm 2 exactly, can prevent from scratching simultaneously circuit board or electronic component.
Described the 3rd bending part 221 is provided with for the projection 222 that contacts with external circuitry, and under identical pressure, the area of contact is more little, and its pressure is more big, so bulge-structure can guarantee that not only contact point is more accurate, but also can guarantee that contact is better.
This electroconductive elastic sheet can be formed its handling ease, low cost of manufacture by a sheet metal bending.
In sum, electroconductive elastic sheet provided by the utility model, because it has two stress deformation points (i.e. first bending part 3 and second bending part 23) and baffle plate 4, the working depth of this electroconductive elastic sheet and length can make the little of more existing electroconductive elastic sheet, and be difficult for being damaged by pressure by excessive pressure and cause plastic deformation, the utility model is applicable in the less electrical equipment in gap.
The above only is the utility model preferred embodiment; its structure is not limited to the above-mentioned shape of enumerating; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
