Embodiment Construction

[0042] The invention will be further described in detail below in conjunction with the embodiments of the accompanying drawings.

[0043] Such as Figure 1~5 As shown, it is the first embodiment of the present invention, which includes an appliance input socket 1 and an electrical connector 2 that can be inserted into each other and rotate relative to each other.

[0044] The electrical connector 2 has an insertion hole 21 in the central part of its upper end surface, and has a first annular groove 22 and a second annular groove 23 concentric with the insertion hole 21, and a columnar first annular groove 23 is arranged in the insertion hole 21. A power supply terminal 31 is provided, a second power supply terminal 32 is provided in the first annular groove 22 , and a third power supply terminal 33 is provided in the second annular groove 23 .

[0045] The appliance input socket 1 is correspondingly provided with a columnar power receiving terminal 41 corresponding to the fir...

Abstract

The invention relates to a safety coupler of a cordless electric appliance, which comprises an appliance input socket and an electric connector, wherein the inside of the electric connected is provided with a power-receiving connecting terminal and at least one power supply contact piece, and the input socket is provided with a cylindrical power-receiving connecting terminal and an annular power-receiving connecting terminal. The safety coupler is characterized in that: the power-receiving connecting terminal corresponding to the power supply contact piece is an elastic piece; the power-receiving connecting terminal is provided with a pushing part which is made of conductive material and is matched with the corresponding power-receiving connecting terminal; when the electric connector is not plugged in the appliance input socket, the power supply contact piece and the corresponding power-receiving connecting terminal are kept in a contact normal open state; when the electric connector is plugged in the appliance input socket, the annular power-receiving connecting terminal directly participates in the contact with the pushing part to push the power-receiving terminal and the corresponding power supply contact piece close to turn on power. Due to the direct cooperation between the annular power-receiving connecting terminal and the pushing part made of the conductive material, a specially arranged contact closing and opening structure is saved, the structure of the safety coupler is simplified, and the production and manufacturing cost of the coupler is reduced.

Description

technical field [0001] The present invention relates to a coupler for household and similar uses consisting of an electrical connector and an appliance input socket, especially a rotary coupling for separate cordless appliances such as cordless electric kettles, cordless frying pans, cordless electric irons, etc. device. Background technique [0002] In existing cordless electric kettles, cordless frying pans, cordless electric irons and other separate electrical appliances, there are couplers, which generally include an appliance input socket arranged at the bottom of the electrical appliance, and a matching power supply base An electric connector is arranged on the top, and when the electric appliance body is rested on the base, the appliance input socket and the electric connector are mated with each other, so as to realize power supply to the electric appliance body. In the above-mentioned cordless electrical appliances, a thermosensitive controller is generally install...
