Description

Coupling plug terminal of protection against electric shock

Technical Field

The utility model relates to the technical field of coupling plug terminals, in particular to an electric shock-preventing coupling plug terminal.

Background

At present, along with the improvement of life quality of people, healthy kitchen appliances such as wall breaking machines, soymilk machines and the like are more and more favored by people, and couplers are indispensable devices of the healthy kitchen appliances such as the wall breaking machines, the soymilk machines and the like. The coupler comprises a plug and a socket with a slot, wherein the socket is matched with the plug in a plugging manner through the slot, so that wire harnesses on the plug are respectively in electrical contact with the wire harnesses on the socket. One proposed use of a reliable coupler is for example patent number CN 202021386374.9.

However, the conventional coupler has the following problems;

1. when the number of the plug-in wiring harnesses is increased, in order to ensure a certain creepage distance, the arrangement interval of the plug-in wiring harnesses cannot be reduced, so that the size of the coupler is larger, and the use requirement of a small-sized and light-weight household appliance is difficult to meet;
