ABSTRACT:
A spring connector includes a barrel made by stamping a metal foil to form with a top opening, a first receiving space, a bottom opening and a cover being capable of being positioned to cover the bottom opening and to space from the bottom opening, a plunger inserted in the barrel from the bottom opening and formed with a head portion exposed outside the barrel, a sliding portion received in the first receiving space, and a second receiving space connected to the first receiving space, a spring insert in the first receiving space and the second receiving space from the bottom opening, of which a bottom portion connects to the cover. Because the cover is made by stamping a metal foil, it is easy to coat a uniform coating layer for improving the conducting quality, and the fabricating time and the cost of the spring connector is reduced.
