The rotating shaft 2203 is further sleeved with a torsion spring 2209, one end of the torsion spring 2209 is fixedly connected with the outer wall of the positioning shell 23, the other end of the torsion spring 2209 is pressed on the outer side of the pressing arm 2204, and the torsion spring 2209 provides elastic force for driving the pressing arm 2204 to clamp.

When the male plug 1 is separated from the female plug 15, the clamping arms 22 are in a clamping state. When the user will carry out the grafting operation, need press the clamp plate 2206 of two sets of arm lock 22 rear ends simultaneously with the finger, thereby open two sets of arm lock 22, insert the second lock pin 16 of female 15 in the location shell 23 of public affairs inserting 1 again, peg graft the back of targetting in place, release two sets of arm lock 22, under the torsion drive of torsional spring 2209, two sets of arm lock 22 self-holding, the fixture block 2205 of arm 2204 front end is pressed this moment just gets into in the draw-in groove 21 on the public affairs inserting 1 shell, thereby insert 15 with public affairs inserting 1 firmly with female, even if the electricity is connected and is received the pulling of external force this moment, female 15 can not separate with public affairs inserting 1 yet, the stability of pegging graft has been improved greatly.

In this embodiment, an annular space is left between the first ferrule 2 and the positioning shell 23, a movable ring 7 is disposed in the annular space, a pair of transverse guide rods 8 is disposed behind the movable ring 7, a through hole 9 is disposed on the fixed plate 3, the guide rods 8 pass through the through hole 9, a cavity 4 for the guide rods 8 to move is disposed behind the fixed plate 3, the front end of each guide rod 8 is fixedly connected with the movable ring 7, a limiting block 10 is fixed to the rear end of each guide rod 8, a spring 11 is sleeved on each guide rod 8, the front end of each spring 11 contacts with the rear surface of the movable ring 7, the rear end of each spring 11 contacts with the front surface of the fixed plate 3, and the spring 11 is in a compressed state, so that the movable ring 7 can move back and forth in the positioning shell 23. A pair of ejector pins 19 are provided at the front end of the second ferrule 16, the ejector pins 19 being adapted to contact the movable ring 7, the length of the ejector pins 19 being greater than the minimum distance between the front surface of the movable ring 7 and the front end surface of the first ferrule 2. A contact block 20 is fixed to the outside of the jack 19, and the contact block 20 is spaced from the front end of the jack 19.

In addition, on location shell 23 and be located the rear of connecting seat 2201 and seted up logical groove 12, and be provided with swing arm 2207 at the rear of rotatory piece, swing arm 2207 penetrates through logical groove 12 in locating shell 23, swing arm 2207 slope sets up, its and the contained angle that presses between arm 2204 are the obtuse angle, the upper end and the rotatory piece of swing arm 2207 are connected fixedly, the lower extreme of swing arm 2207 is located between activity ring 7 and the contact piece 20, activity ring 7 and contact piece 20 all are located the scope that covers when the swing rotates.

It should be noted that: the moment generated by the elastic force of the spring 11 acting on the lower end of the swing arm 2207 is larger than the moment generated by the torsion force of the torsion spring 2209 acting on the pressure arm 2204; further, the magnetic attraction force between the first magnet 5 and the second magnet 17 is larger than the elastic force of the spring 11. Thus, after the female plug 15 is separated from the male plug 1, the spring 11 can drive the swing arm 2207 to rotate counterclockwise, so as to open the clamping arms 22, that is, before the male plug 1 is plugged, two sets of the clamping arms 22 are in an open state.

In the process of butting the female plug 15 and the male plug 1, when the second ferrule 16 is about to contact the first ferrule 2, the ejector rod 19 will contact the movable ring 7 first, the magnetic attraction force makes the ejector rod 19 push the movable ring 7 backwards, the swing arm 2207 rotates clockwise, and the clamping arm 22 is clamped gradually. When the inserting pin 18 is completely inserted into the inserting hole 6, the clamping arms 22 are just completely clamped, and the clamping blocks 2205 completely enter the clamping grooves 21, so that the butt joint is completed and the male pin 1 and the female pin 15 are locked together. So, when inserting public 1 and female 15 of inserting, need not manual opening arm lock 22, arm lock 22 open with press from both sides tight and can both accomplish automatically, operate simplyr, more humanized.

The operation steps of pulling out the female plug 15 are as follows: pressing plates 2206 at the rear parts of the two groups of clamping arms 22 by hands to gradually open the clamping arms 22, wherein in the process, the swinging arms 2207 move anticlockwise, the swinging arms 2207 rotate by a certain angle and then contact with the contact blocks 20, after the swinging arms 2207 rotate by the certain angle, the clamping blocks 2205 at the front ends of the pressing arms 2204 are just separated from the clamping grooves 21 on the shell of the female plug 15, and the male plug 1 and the female plug 15 are unlocked; the pressing plate 2206 is continuously pressed, the swing arm 2207 is in contact with the contact block 20 to generate outward thrust on the contact block 20, the thrust is transmitted to the second inserting core 16, the second inserting core 16 is pushed outward to separate the inserting pin 18 from the inserting hole 6, when the two groups of clamping arms 22 are completely opened, the second inserting core 16 is pushed out for a certain distance, the magnetic attraction force between the first magnet 5 and the second magnet 17 is weaker, a user can easily pull the second inserting core 16 out of the positioning shell 23, so that the female plug 15 is completely separated from the male plug 1, the pulling operation is completed, the spring 11 drives the movable ring 7 to reset in the pulling process, the clamping arms 22 are kept in an opening state, and the next plugging operation is facilitated.

Therefore, the clamping arm 22 can be opened by pressing the pressing plate 2206, and the inserting pin 18 can be separated from the inserting hole 6, so that two purposes are achieved, and the pulling operation is convenient.

Referring to fig. 1 and 2, in the present embodiment, guide grooves 13 are further symmetrically formed in an inner wall of a front end of the positioning shell 23, the guide grooves 13 are disposed along a front-rear direction of the positioning shell 23, a front end of the guide groove 13 extends to a front end face of the positioning shell 23 to form an opening, a slider 14 is fixed on a surface of the second ferrule 16, and the guide grooves 13 are used for allowing the slider 14 to enter and slidably engage with the slider 14. When the front end of the second ferrule 16 enters the positioning shell 23, the sliding block 14 enters the guide groove 13 along with the sliding block, and the guide groove 13 has a guiding function, so that after the front end of the second ferrule 16 enters the positioning shell 23, the second ferrule 16 can move along a straight line without shaking and dislocation, thereby ensuring that the contact pin 18 is accurately aligned with the jack 6 and improving the success rate of magnetic attraction butt joint.

The slider 14 in this embodiment has a leading end formed in an arc shape. The arc-shaped guide portion allows the slider 14 to enter the guide groove 13 more smoothly.

As shown in fig. 2, in order to prevent the fingers from slipping when pressing the pressure plate 2206, the surface of the pressure plate 2206 is also provided with anti-slip stripes 2208 in the present embodiment.
