Embodiment Construction

[0015] The safety electrical connector is composed of a connecting head with a wire and a connecting seat without a wire that are plugged into each other. For example, the electric plug of an electric kettle is arranged under the kettle. When heating, the socket in the bottom of the kettle is aligned with the plug for connection. When not plugged in, as shown in FIG. Isolation ring 7 and guide ring 13 surround and isolate inner contact piece 10 and outer contact piece 11 ( Figure 1-b ). The guide ring 13 is arranged on the upper end of the isolation ring 7, and its central hole 14 is opened and corresponds to the grounding post 2 at the center of the connection seat, and the annular hole of the guide ring corresponds to the insulating ring 4 on the connection seat. A limiter 18 is horizontally placed in the middle of the spacer ring 7, and the frame bottom 25 of the limiter is clamped by the ground contact piece 12 and the limit elastic piece 15 on both sides ( Figure 1-c )...

Abstract

The invention is a safety electrical connector, including connection head and connection seat, where there is a circular grounding end and a grounding column arranged in the connection seat, there are electric contact pieces arranged on the connection head, there is an isolating ring arranged between each pair of electric contact points in the connection head, a spacer is arranged in the isolating ring; the displacement of the isolating ring is under the control of that of the spacer and that of the spacer is controlled by that of the grounding column. The invention has a fully sealed structure, each pair of electric contact points is sealed and isolated before reaching the position as inserted, the spacer is controlled by the grounding stick and adopts an interlinked locked structure and simultaneously in structure, it assures only when the grounding wire is contacted can other contact points be closed, thus radically, avoiding hidden trouble of creepage of other components of electric appliance. In addition, it also designs two draining direct current channels to prevent accident hidden trouble of overturn and leakage.

Description

technical field [0001] The invention relates to a power supply connection device, in particular to a connector for a heating power supply of a household electric heating container such as an electric cup or an electric kettle. Background technique [0002] The electric heating connectors of existing household electric heating capacitors generally include plugs and sockets. Household electric heating containers without wires are commonly called cordless electrical connectors. Continuous improvement, such as CN1056474C proposed a cordless electrical appliance and its connector patent, which is a connector that can directly see the contacts of the power phase wires. conductive objects, electric shock accidents will occur, thus endangering personal safety. CN2422757Y proposes an electrical connector patent to modify the above-mentioned cordless electrical connector so that it cannot see the contact head of the power phase line contact under normal conditions, and isolates the c...
