Embodiment
The embodiment of most preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing:
First the working method of the utility model most preferred embodiment is described, with reference to figure 1, Fig. 2, and shown in composition graphs 3, a kind of surface-mounted elastic sheet 1 of most preferred embodiment of the present utility model, for the electrical connection between Anneta module and radio-frequency front-end (not shown), it is formed by modes such as bendings by a sheet metal, comprise a flat construction section 11, this construction section 11 is for installing the circuit board 2 (with reference to Fig. 3) being positioned to radio-frequency front-end, an elastic arm section 12 is extended to form through three bendings from an ora terminalis of described construction section 11, bent by the ora terminalis away from construction section of this elastic arm section 12 and extend to form a connecting section 13, this connecting section 13 is divided into two parts: inclination riser portions 131 and inclination falling portion 132, and position is provided with prominent ribs 135 near being connected of inclination riser portions 131 and inclination falling portion 132, in order to strengthen structural strength and to provide the electrical connection area contacted with Anneta module.Further with reference to shown in figure 1 and Fig. 2, described inclination riser portions 131 is formed along the direction that tilts upward by the ora terminalis away from construction section 11 of elastic arm section, and described inclination falling portion 132 is extended to form towards the direction bending at construction section 11 place by the free end of described inclination riser portions 131.
It should be noted that, described inclination riser portions 131 and inclination falling portion 132 define a spatial accommodation jointly, the ora terminalis away from inclination riser portions 131 of described inclination falling portion 132 extends and bends, the free end of inclination falling portion 131 is made to take in described spatial accommodation, like this, preventing the end of connecting section 13 (i.e. the free end of inclination falling portion 131) from revealing puts outside, and when avoiding multiple shell fragment to load in mixture, entanglement knotting and unexpected hook cause shell fragment disabler.
Apparently, when Anneta module (not shown) compresses described prominent ribs 135, there is compressive deformation in described elastic arm section 12, provides flexible restoring force to ensure be returned to initial condition when Anneta module moves back and compresses.
Further, from the lateral margin of described inclination riser portions 131 bending respectively and being extended with side to rib 133 towards described inclination falling portion 132 direction, this side direction rib 133 has the first ora terminalis A interconnected with inclination riser portions and the second contrary ora terminalis B (as shown in Figure 1), and the both sides of the connecting section 13 that is placed in symmetrically, like this, due to the adhewsive action of side direction rib 133, make the structural strength of the inclination riser portions 131 adding connecting section 13.In addition, the first ora terminalis B of described side direction rib 133 is also provided with the guiding edge 134 with the described identical inclination angle of inclination falling portion 132, preferably, described guiding edge 134 outwards exceed the outer surface of inclination falling portion 132.When Anneta module is passed to shell fragment 1 from side direction (X-direction namely Fig. 3), when namely pushing the inclination falling portion 132 of described connecting section 13, because guiding edge 134 outwards exceeds the outer surface of described inclination falling portion 132, first described Anneta module can be pushed through on guiding edge 134, due to oblique guide function, a cushioning effect being pressed to inclination falling portion 132 (i.e. the front end of connecting section 13) transition is provided, and share certain internal stress, when Anneta module passes the precalculated position be connected with shell fragment electrical contact further, described inclination riser portions 131 can not make connecting section 13, and towards X-direction upset, stress is excessive and lost efficacy due to the booster action of side direction rib 133.
Moreover; on the lateral margin of described construction section 11, bending is extended with the extension 111 with elastic arm section 12 homonymy respectively; the space-closed that described extension 111 makes described side direction rib 133 fixed with construction section 11 boundary, the side direction rib 133 of protection shell fragment 1 can not the deformation failure because of extraneous pull hook further.
In addition, described extension 111 is extended with a stopper section 112 towards described elastic arm section 12 bending, described stopper section 112 press against elastic arm section 12 from top makes this elastic arm section 12 form a horizontal absorption district 121 supplying SMT technique suction nozzle to draw (as Fig. 1, shown in Fig. 2), the structural stability of extension 111 can be strengthened by stopper section, make elastic arm section 12 have certain bending degree of freedom simultaneously, certain angle even if elastic arm section 12 is inclined upwardly, also can ensure that described horizontal absorption district 121 is the level of state by the pressing effect of stopper section 112, like this, certain manufacture deviation can be allowed.
In sum, the utility model is by described side direction rib 133, strengthen the structural strength of elastic arm section 12 in the anti-pushing force of side direction, and, share and guide by described guiding edge 134 lateral thrust that connecting section 13 bears, and the effect of described extension 111 and stopper section 12, further ensure the structural strength of shell fragment, improve stability and the reliability of shell fragment.
Meanwhile, by above-mentioned setting, also achieve the generation of the failure conditions such as the distortion preventing shell fragment from being caused by unexpected hook.
The above, only list most preferred embodiment of the present utility model, and can not limit the scope of the utility model enforcement with this, any similar technical scheme all should belong to disclosed content.
