Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
As illustrated in figs. 2-7, embodiments of the present invention are related to a kind of rotating connectors of conductor needle ground connection preferential contact,
Including socket 2 and plug 1, the end face of the socket 2 is provided with the jack being inserted into for plug 1, arranges inside the socket 2
There are several electrical terminals and ground terminal 3, be equipped with inside the plug 1 and each electrical terminals in socket 2 and connect
Ground terminal 3 is corresponding to connect electric mortiser needle and ground connection contact pin 8, is disposed with protruding portion on the outside of the side of the ground connection contact pin 8, this is prominent
The contact of arcuate projection and ground terminal 3 when portion guarantees that plug 1 rotates along the radially arrangement of ground connection contact pin 8 out
Earlier than other electrical terminals and the contact for connecing electric mortiser needle.
Preferably, the inside two sides of the 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 the plug 1 be disposed be inserted into it is slotting
The guiding inserting column 9 of seat 2, axially insertion is disposed with ground connection contact pin 8, the inner sidewall peace of the plug 1 to the side wall of the guiding inserting column 9
Equipped with zero line contact pin 6 corresponding with fire line terminal 5 and zero terminal 4 and zero line side contact pin 7.
As a kind of embodiment of the invention, as shown in figure 5, when plug 1 is inserted into socket 2, each connecting terminal
All be with each contact pin it is discontiguous, when plug 1 rotate when, due to ground connection contact pin 8 side on the outside of be disposed with protruding portion,
So the protruding portion can be in contact prior to other contact pins with ground terminal 3, then proceed to other terminals after rotation in plug 1 with
Corresponding contact pin is in contact, and realizes fully switched on.
As a kind of specific embodiment, the protruding portion be arcuate projection, make be grounded contact pin 8 section be in
Ellipse, arcuate projection are conducive to be grounded contact pin 8 and 3 easy contact of ground terminal, and oval section also facilitates ground connection to insert
The processing of needle 8.
As another specific improvement, close end is leaned on the fire line terminal 5, zero terminal 4 and ground terminal 3
Position is arranged with the portion of arching upward 10, arch upward portion 10 and the corresponding zero line contact pin 6, zero line side contact pin 7 and ground connection 8 phase of contact pin
Contact, with certain elasticity, can guarantee can generate certain deformation when terminal and identical contact pin contact in the portion 10 that arches upward, and keep
The two comes into full contact with.
In order to further guarantee that ground terminal 3 can contact earlier with ground connection contact pin 8, on the ground terminal 3
Arch upward portion 10 lateral surface in inclined-plane, the high order end on the inclined-plane is first in contact with ground connection contact pin 8 when plug 1 rotates, guarantor
Demonstrate,prove preferential ground.
The configuration of the present invention is simple enables the ground connection for being grounded contact pin first and other contact pins by changing the shape of ground connection contact pin
