[specific embodiment]
In order that the technical scheme of this patent and technique effect are clearer, with reference to the accompanying drawings and examples to this patent
Specific embodiment be described in detail.
Embodiment one:
As shown in Figure 1 to Figure 4, the anti-open circuit adapter in the present embodiment includes socket 1 and plug 2, and socket 1 and plug 2 can be joined
Box-like connection.
Defining p direction in Fig. 2 is in front of socket 1, and socket 1 includes Socket casing 11, jack panel 12, jack panel pressing plate 13,
Jack contact 14 and anti-open circuit set 15.Jack panel 12 engage with jack panel pressing plate 13 after in Socket casing 11, axially
Form jack containing cavity 16 and anti-open circuit set containing cavity 17, jack containing cavity 16 is set with anti-open circuit set containing cavity 17 interval
Put, jack contact 14 is in jack containing cavity 16.In anti-open circuit set containing cavity 17, it includes anti-open circuit set 15
Spring 151 and contact block 152；Spring 151 and contact block 152 are sequentially arranged in anti-open circuit set containing cavity 17 from inside to outside, and
Spring 151 is spacing by the end of anti-open circuit containing cavity.It is provided with folding face 141, contact block 152 one end supports in the middle part of jack contact 14
It is connected on spring 151, other end is connected on the folding face 141 of its both sides jack contact 14 so that each jack contact
14 communicate with each other.Jack contact 14 front end is contacted with following contact pins 24, and wire is fixed in rear end.
Plug 2 includes plug casing 21, Plug pin patch bay 22, push rod 23 and contact pin 24.Plug pin patch bay 22 in plug casing 21,
Plug pin patch bay 22 is axially arranged with contact pin 24, is provided with push rod 23 between two successive pins 24.Contact pin 24 relative position and jack contact
The relative position of part 14 corresponds, and push rod 23 relative position is corresponded with the position of contact block 152；And described contact pin 24 energy
With its interference fit in insertion jack contact 14, after push rod 23 can insert accommodating intracavity contact contact block 152 end of anti-open circuit
Compression spring 151 further, so that contact block 152 departs from the jack contact 14 folding face 141 of both sides.
6 core sockets 1 and plug 2, socket 1 uniform intervals on the circumference around axle center are provided with 6 jack containing cavities 16,6
Individual anti-open circuit containing cavity uniform intervals are between 2 adjacent jack containing cavities 16；And corresponding with socket 1 be plug 2 axle center
