Problems solved by technology

As soon as the plug of the device is plugged into the socket, an electrical circuit is formed. During the process from the beginning of plugging to the completion of the plugging, the electrical contact terminals in the plug and the electrical contact terminals in the socket move relative to each other, and arcs are often drawn, and the arc temperature is high. , especially the electrical contact terminals in the plug will be oxidized, causing damage to it over time, affecting its service life and low safety

Embodiment Construction

[0011] Fig. 1 shows the cross-sectional view of the basic structure of the present invention. The cordless electrical connection device includes a circular plug 8 and a socket 22 matched with the circular plug. Corresponding electrical contact terminals are respectively arranged in the plug 8 and the socket 22. At least one movable contact piece in the ring plug 8 is provided with a pressing bar 13 separating the moving and static contact pieces. One end of the pressing bar 13 passes through the bottom 7 of the plug and is in movable contact with the outer ring 26 of the socket 22. The middle part of the pressing bar 13 The curved hook 16 of the extension arm 15 rides on the corresponding movable contact piece, and the other end of the depression bar 13 is provided with a return spring 3 which limits its position, and the upper end of the return spring 3 is arranged in the block 5 . The main body of the ring plug 8 is composed of inner and outer ring walls 11 and 12. The inner ...

Abstract

A wireless electric connector comprising a circular plug and its matching socket. In the plug and the socket, there are respectively corresponding electric contact terminals. The characteristics are: the depression rod on at least one moveable contact of the plug for isolating moveable contact from stationary contact; the one ed of the rod passes through the bottom of the plug being contacted with moveable contact of outer ring of the socket; the stretching arm from the middle of the rod is booked-touching the above-mentioned moveable contact; on the other end of the rod is equipped with a return-spring for limiting the rod; the other end of the spring is on a block. During the operation of inserting the plug, from beginning to the end, no contact occurs between phase-line moveable contact and stationary contact, so no production of are, keeping the contact sleeve no fault, achieving long service life of the connector.

Description

technical field [0001] The invention relates to a cordless electrical connection device, in particular to a cordless electrical connection device for an electric kettle. Background technique [0002] The existing cordless electrical connection device includes a ring plug and a socket matched with the ring plug, and corresponding electrical contact terminals are respectively arranged in the plug and the socket. As soon as the plug of the device is plugged into the socket, an electrical circuit is formed. During the process from the beginning of plugging to the completion of the plugging, the electrical contact terminals in the plug and the electrical contact terminals in the socket move relative to each other, and arcs are often drawn, and the arc temperature is high. , especially the electrical contact terminals in the plug will be oxidized, causing damage to it over time, affecting its service life and low safety. Contents of the invention [0003] The technical problem ...
