The portion of rising, the portion that arches upward contacts with corresponding zero line contact pin, zero line side contact pin and ground connection contact pin.
Further, the lateral surface in the portion that arches upward on described ground terminal is in inclined-plane, and the high order end on the inclined-plane is in plug
It is first when rotation to contact with ground connection contact pin.
Beneficial effect：The present invention relates to a kind of conductor needle is grounded the rotating connectors of preferential contact, simple structure passes through
Change ground connection of the shape of ground connection contact pin to enable ground connection contact pin first to connect with other contact pins, it is ensured that safety when electrical equipment is powered,
The structure of socket and plug need not be changed, without the need for re-molding, ground connection contact pin need to be only changed, with good popularization and application
Value.

Specific embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than restriction the scope of the present invention.In addition, it is to be understood that after the content for having read instruction of the present invention, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
As illustrated in figs. 2-7, embodiments of the present invention are related to the rotating connectors that a kind of conductor needle is grounded preferential contact,
Including socket 2 and plug 1, the end face of described socket 2 is provided with the jack for the insertion of plug 1, the described inside of socket 2 arrangement
There are several electrical terminals and ground terminal 3, be provided with inside described plug 1 relative with each electrical terminals in socket 2
That what is answered connects electric mortiser pin, and the side outside of described ground connection contact pin 8 is disposed with protuberance, footpath of the protuberance along ground connection contact pin 8
To it is outwardly disposed guarantee plug 1 rotate when arcuate projection contact with ground terminal 3 earlier than other electrical terminals with connect
The contact of electric mortiser pin.
Preferably, the inside both sides of described socket 2 have been arranged symmetrically fire line terminal 5 and zero terminal 4, described
Fire line terminal 5 and zero terminal 4 between side be disposed with ground terminal 3, the middle part of described plug 1 be disposed be inserted into it is slotting
The guiding inserting column 9 of seat 2, the side-wall shaft of the guiding inserting column 9 is disposed with ground connection contact pin 8 to embedded, and the medial wall of described plug 1 is pacified
