Dynamic), thus ensureing the hole wall reliable contacts of contact site on resiliently overhanged end and jack it is ensured that the reliability of grafting, and often enclose
Multiple elasticity fingertips are respectively provided with bar shaped flexible substrate, each elasticity fingertip on each circle bar shaped flexible substrate respectively with jack hole wall
Elastic Contact, makes to produce a lot of contact points between conductive spring and jack, between the number of contact point is with two neighboring elasticity fingertip
Spacing relevant with the number of turns of bar shaped flexible substrate, theoretically, the number of contact point can be infinitely many, and so a lot of connects
Contact increased the contact area of conductive spring and jack together, makes the resistance between contact pin and jack less, such that it is able to carry
Bigger electric current, is not required to increase the radial dimension of contact pin and corresponding connectors simultaneously again, be conducive to power connector miniaturization,
Lightweight makes.
