Or the inner hole is deviated from the lower tolerance, the outer diameter is deviated from the upper tolerance, the contact fit is too tight, the friction force is often larger than the elastic force of the spring, after the contact cap is pressed down, the contact cap cannot rebound freely, the clamping phenomenon is generated, the contact disconnection between the inner conductors is caused, and the transmission function is failed. Because the spring is used, the spring with a certain length is inevitably needed when certain elastic force is generated, and because the spring exists, a certain circumferential space is needed, so the length and the diameter of the inner conductor are restricted by the spring, and the application range has certain limitation.
