The first fulcrum and the second fulcrum of leaf spring are touched with the inner wall of sheath respectively, when several of contact pin and jack leaf spring grafting, are made
The cantilever beam stress for obtaining original every leaf spring becomes simply supported beam stress, due to the change of stress, reduces
The stress that the fixing end of original cantilever beam leaf spring is born, improves the contact area of simply supported beam leaf spring and contact pin, has insertion
Power, separating force are respectively less than the leaf spring formula jack of same material, comparable size, and contact reliability is high, contact resistance is small, friction damage
Consume advantage small, that the service life is long and at low cost.
Realizing the specific technical solution of the object of the invention is:
A kind of high current leaf spring formula contact, feature include jack, sheath and contact pin, and the jack is tubular element, outer diameter
It is equipped with step, for one end barrel of tubular element along axially cutting at several petal-like leaf springs, the free end of leaf spring is equipped with loudspeaker
The connecting pin of the first fulcrum stuck up outside mouth shape, leaf spring and barrel is equipped with the second fulcrum of recessed circle and bending；
The sheath is tubular element,
The plug division of the contact pin is divided into cylindrical member, and the end of grafting part is equipped with chamfering；
The sheath is set to the outside of several leaf springs of jack, and the inner hole of sheath end and the step of jack outer diameter are clamped, jack
The first fulcrum and the second fulcrum of upper leaf spring are touched with the inner wall of sheath respectively；
One end that contact pin is equipped with chamfering is plugged in several leaf springs of jack, and the outer circle of the inner wall of several leaf springs and contact pin is touched
And.
The recessed circle is open circles, between two adjacent leaf springs and the connecting pin of barrel.
The present invention in leaf spring using the first fulcrum and the second fulcrum is arranged, when sheath is set in several leaf springs on jack
When outside, the first fulcrum and the second fulcrum of leaf spring are touched with the inner wall of sheath respectively on jack, when several of contact pin and jack
When leaf spring grafting, so that the cantilever beam stress of original leaf spring becomes simply supported beam stress, due to changing for stress
Become, reduces the stress that the fixing end of original cantilever beam leaf spring is born, improve the contact area of simply supported beam leaf spring and contact pin, have
There are insertion force, separating force to be respectively less than the leaf spring formula jack of same material, comparable size, and contact reliability is high, contact resistance is small,
Frictional dissipation is small, the service life is long and advantage at low cost.
Detailed description of the invention
