Description
Technical field
The present invention relates to a kind of wireless electric connection device, refer to be used for the wireless electric connection device of electric kettle especially.
Background technology
Existing wireless electric connection device, it comprises annulus plug and the socket that matches with the annulus plug, respectively establishes corresponding electric contact terminal in the plug and socket.The plug one of this device is pegged graft with socket; just form electric loop; begin to be plugged to and peg graft in the process that finishes; electric contact terminal in the plug and the electric contact terminal relative motion in the socket are drawn electric arc through regular meeting, the arc temperature height; especially the electric contact terminal in can this plug of oxidation; in the course of time, it is caused damage, it is low to influence its useful life and fail safe.
Summary of the invention
The technical problem to be solved in the present invention is: can not produce electric arc in the process that provides a kind of plug and socket to peg graft, thus long, safe wireless electric connection device of life-span.
Technical scheme of the present invention is: a kind of wireless electric connection device, comprise annulus plug and the socket that matches with the annulus plug, respectively establish corresponding electric contact terminal in the described plug and socket, it is characterized in that at least one movable contact spring of described plug is provided with the depression bar that dynamic and static contact is separated, one end of described depression bar passes the plug bottom and contacts with the outer toroid activity of socket, adjutage hook in the middle of the depression bar rides on the described movable contact spring, depression bar other end periphery is provided with its spacing back-moving spring, and the upper end of back-moving spring is located in the chock.
The invention has the beneficial effects as follows: when plug was not pegged graft, depression bar was in lowest order under the effect of back-moving spring elastic force, and the projection of its hook rides on the phase line movable contact spring, made the phase line moving contact away from the phase line fixed contact.The internal ring wall of plug turns down the cover plate of socket, and the outer toroid of socket is then pushed up the depression bar lower end.When plug and socket had been pegged graft, the outer toroid of socket was up pushed up depression bar and is made it be in highest order, and its projection is separated with the end of phase line movable contact spring, and the phase line movable contact spring sets back, and the phase line moving contact contacts with the phase line fixed contact and the electricity connection.Begin to be plugged to and peg graft in the process that finishes, though the phase line contact of socket and plug outer touches the cover relative motion, because phase line moving contact and phase line fixed contact access failure, phase line contact and touch outward between the cover and can not produce electric arc, it is intact to guarantee to touch cover, makes this arrangements of electric connection long-life.
