Abstract
The utility model discloses a three-phase four-wire socket and a corresponding plug. The three-phase four-wire socket comprises a socket body and jacks arranged on the socket body, wherein the jacks comprise three live wire jacks arranged in the same column and earthing wire jacks symmetrically arranged at the two sides of the live wire jack column; the three-phase four-wire plug comprises a plug body and plug pins arranged on the plug body; and the plug pins comprise live wire plug pins matched with a live wire in the same column and earthing wire plug pins. By adopting the technical scheme, the utility model has the advantages that the plug is connected to a motor; when in use, the plug is plugged in the socket; when the motor rotates reversely to the required direction, the plug is pulled out and rotated at 180 degrees, and then plugged in the socket, so that the inconvenience of exchanging wires by opening the socket or the plug is saved, and time and labor are also saved. The three-phase four-wire socket has simple structure, is convenient to modulate phase and is applicable to small and medium-power three-phase motors and other small and medium-power three-phase electrical appliances.
Description
Technical field
The utility model relates to a kind of electrical equipment utensil, relates to the three-phase four-wire socket of a kind of quick correction motor reversal connection specifically, also relates to and the corresponding plug of this three-phase four-wire socket.
Background technology
At present, the three-phase four-wire socket firewire jack in market all is a triangular arrangement, and the socket of this structure and the plug that matches with it can not be anti-reverse, in case motor is connect instead, when finding that motor and required direction are inconsistent, socket or plug must be opened, the position of live wire is transferred, so very inconvenient, and lose time, poor stability, the production cost height, efficient is low.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned deficiency, and a kind of three-phase four-wire socket and corresponding plug are provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of three-phase four-wire socket, comprise pedestal and the jack that is arranged on the pedestal, jack comprise A that same column is provided with to firewire jack, B to firewire jack and C to firewire jack, B is arranged on the centre position to firewire jack, A is separately positioned on the two ends of B to firewire jack to firewire jack and C to firewire jack, is provided with the earth connection jack in firewire jack row bilateral symmetry.
Above-mentioned three-phase four-wire socket, the aperture of described earth connection jack is less than the aperture of firewire jack.
A kind of three-phase and four-line plug that matches with three-phase four-wire socket, comprise plug body and be arranged on plug post on the plug body, the plug post comprise with live wire match A that same column is provided with to live wire plug post, B to live wire plug post and C to live wire plug post, B is arranged on the centre position to live wire plug post, A is separately positioned on the two ends of B to live wire plug post to live wire plug post and C to live wire plug post, is provided with earth connection plug post in a side of live wire plug post.
The above-mentioned three-phase and four-line plug that matches with three-phase four-wire socket, the diameter of described earth connection plug post is less than the diameter of live wire plug post.
Adopt technique scheme, the utility model has following advantage: plug of the present utility model is received on the motor, during use, be inserted on the socket, rotate when opposite when finding motor and required direction, plug dialled down rotate 180 and spend again on the socket just passablely, saved the inconvenience of opening socket or plug line transfer at present, time saving and energy saving.The utility model is simple in structure, and phase modulation is convenient during use, is applicable in other three-phase electric apparatus of middle low power threephase motor and middle low power.
