Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation scope of the present utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
As illustrated in figs. 2-7, embodiment of the present utility model is related to a kind of the rotary of conductor needle ground connection preferential contact and connected
Device, including socket 2 and plug 1 are connect, the end face of described socket 2 is provided with the jack inserted for plug 1, described socket 2
Portion is disposed with inside several electrical terminals and ground terminal 3, described plug 1 and is provided with and each power connection end in socket 2
The corresponding ground connection contact pin 8 of son, the side outside of described ground connection contact pin 8 is disposed with protuberance, and the protuberance is inserted along ground connection
The radially arrangement of pin 8 ensures that arcuate projection contact with ground terminal 3 is earlier than other power connection ends when plug 1 is rotated
Son and the contact for being grounded contact pin 8.
