The prior art：
1 base portion 11 of elastic piece structure
Shrapnel 12
The utility model：
2 rectangular housing 21 of adapter
Hold 22 elastic piece structure 3 of groove
31 shrapnel 32 of base portion
Cantilever 321 compresses arm 322
Connecting portion 33
Specific embodiment
It please join shown in Fig. 1 to 5, be the knot of 2 elastic piece structure 3 of prior art elastic piece structure 1 and the utility model adapter
Structure schematic diagram.
It please join Fig. 4 and Fig. 5, the utility model is a kind of 2 elastic piece structure 3 of adapter, including base portion 31 and from base portion 31
Obliquely outward shrapnel 32, the angle between the shrapnel 32 and base portion 31 are 17~18 degree.So set, incorporated by reference to
Fig. 1 to 3, compared to angle larger between shrapnel 12 of the prior art and base portion 11, the utility model has smaller modeling
Property deflection can preferably extend the service life of product.Specifically, angle between shrapnel 32 and base portion 31 in the prior art
It is 17.8~18.8, angle is 17~18 degree between the utility model shrapnel 32 and base portion 31.
Experimental verification is as follows：Use SUS301-1/2H materials；Elasticity modulus is 19700kgf/mm2；Subdue intensity
61kgf/mm2；The elastic piece structure 1,3 of Poisson's ratio 0.29.Had using arbitrary two kinds in the prior art and the utility model identical
Length but shrapnel 32 with above-mentioned different angles is compared：
After shrapnel 32 is made to push 1.00mm, shrapnel 32 of the prior art has the set deformation volume of 0.47mm, and originally
The shrapnel 32 of utility model only has the set deformation volume of 0.15mm.The set deformation volume of the utility model is much smaller than existing
There is the set deformation volume in technology.
Preferential, the angle between the shrapnel 32 and base portion 31 is 17.5 degree.In this way, with smaller permanent deformation
Amount.
The shrapnel 32 includes being inclined outwardly the cantilever 321 of extension from base portion 31 and bending inwards from 321 end of cantilever
Extension compresses arm 322 to what is compressed outward, and the angle is the angle between the cantilever 321 and base portion 31.In this way,
The arm 322 that compresses is not easy to stab external equipment.
The base portion 31 is adhering on the adapter 2.In this way, the base portion 31 can preferably support the adaptation
Device 2 may be in other embodiments, between the base portion 31 and adapter 2 non-direct contact.The shrapnel 32 is from base
31 middle part of portion, which punctures, to extend outwardly, and such structure is more firm.It in other embodiments, can also be from other portions of base portion 31
Position extends.
The elastic piece structure 3 includes two base portions 31 positioned at 2 both sides of adapter, is equipped on two base portion 31 described
Shrapnel 32.In this way, 2 both sides of adapter can be compressed by preferable elasticity.
The elastic piece structure 3 includes the connecting portion 33 to laterally attached two base portion 31.In this way, the elastic piece structure
3 is more firm, is easily installed positioning.
Spacing of two base portion 31 at the connecting portion 33 is more than far from the spacing at the connecting portion 33.Such as
This, two base portion 31 can be relatively held fixedly in 2 both sides of adapter, prevent from being detached from outward.
The width of the connecting portion 33 is less than the width of the base portion 31 in the longitudinal direction.In this way, shrapnel knot can be convenient for
The positioning of structure 3, and material saving cost.
The adapter 2 includes rectangular housing 21 and holds institute from what 21 outside of rectangular housing was recessed inwardly to accommodate
State the fixing groove 22 of connecting portion 33.In this way, the elastic piece structure 3 can strong fix in it is described fixing groove 22 in, be not easy
It is detached from the adapter 2.
Specifically, 2 elastic piece structure 3 of adapter is 2 elastic piece structure 3 of SC fiber adapter.In other embodiments,
The elastic piece structure 3 is readily applicable on other adapters or other connectors.
