Set 401e is semi-open type structure setting, and active force when carrying out installing and dismounting by opening and closing mode, and being closed can use magnetic force
The mode of attraction, and the internal diameter of the internal diameter and connector 402 of intermediate bad block 401a, plug 403 is adapted.
4~16 signal referring to Fig.1, connector 402 further include end 402a, fixing sleeve 402b, magnetic force block 402c in set, lead
Electricity set 402d and plugging block 402e.Specifically, end 402a includes the conflict end 402a-1 extended outward and axially extends
Rotary table 402a-2, fixing sleeve 402b is sheathed on the rotary table 402a-2 of extension, end and contradict end 402a-1 and contradict and limit, and
After actuating sleeve 401 is arranged installation, contradicts and limit between limited block 401c and conflict end 402a-1.Conductive sleeve 402d runs through end
402a, and extend outwardly along the direction rotary table 402a-2.The sliding eye that setting is slided for conductive sleeve 402d in magnetic force block 402c in covering,
Magnetic force block 402c in set is slided in fixing sleeve 402b.Further, magnetic force block 402c's is one of sliding in covering
Extend outwardly setting setting nesting 402c-1 on dynamic hole, and nested 402c-1 is set on conductive sleeve 402d, and outside nesting 402c-1
Conductive column 402c-2 is connected, the internal diameter of conductive column 402c-2 can be greater than the internal diameter of conductive sleeve 402d, or can pass through
The setting of length citing citing, so that conductive column 402c-2 non-contravention conductive sleeve 402d when sliding, and conductive column 402c-2, conduction
It is mutually conductive to cover 402d and nesting 402c-1.Further, also integrally connected setting buckles block on magnetic force block 402c in covering
402c-3, spring element 402c-4 and interior magnetic ring 402c-5, three can be with the sliding of magnetic force block 402c in covering and for cunnings
It is dynamic.
Specifically, the notch 402c-6 and penetrating mouth 402b- of the one end fixing sleeve 402b setting is arranged on buckle block 402c-3
1 and slot 402b-2, slot 402b-2 are the centrosymmetric scalloped recess in both ends, and two sides are arranged for conductive column 402c-2 in slot
The spring eye stretched out for spring element 402c-4 is arranged in the hole of discrepancy, center.Assembly relation are as follows: when fixing sleeve 402b is arranged completion
Afterwards, i.e., illustrated by the variation of Figure 15 to Figure 14, buckle block 402c-3 is corresponding with penetrating mouth 402b-1 and can freely enter and leave, conductive
Column 402c-2 is corresponding with slot 402b-2 inner hole freely to be entered and left, and the spring element 402c-4 of the center of plugging block 402e and stretching connects
It connects, one end of fixing sleeve 402b is limited, limit its pop-up, spring element 402c-4 is spring.And plugging block 402e can be around
Center rotates by a certain angle.While in the present embodiment in order to realize conductive sleeve 402d sliding, plugging block 402e occurs opposite
The hole entered and left for conductive column 402c-2 is closed or is got out of the way in rotation.In the present embodiment, plugging block 402e further includes guide surface
402e-1 or banking pin 402e-2, guide surface 402e-1 and conductive column 402c-2 corresponding matching, due to banking pin 402e-2
With elastic back hook, restore deformation after banking pin 402e-2 is inserted into spring eye, elastic back hook and spring eye act on, realize and block
The limit of block 402e.
7 ~ 18 signal referring to Fig.1, plug 403 and connector 402 have symmetrical assembling structure, therefore set on plug 403
Set structure corresponding with connector 402.Specific symmetric relation, 8 signal referring to Fig.1, when plug 403 is docked with connector 402, respectively
The symmetrical matching relationship in position and assembling process are as follows: conductor wire first is separately connected plug 403 and connector 402, on the 402a of end
The hole of supply lines contact is set, electrical connection is realized by the contact with conductive sleeve 402d.Actuating sleeve 401 is sheathed on fixing sleeve 402b
Outer surface, between the magnetic ring 401d of outer ring and the interior magnetic ring 402c-5 of inner ring have magneticaction, can be with same sex phase
The magnetic force of suction, when the actuating sleeve 401 of two sides is mobile to centre, the interior magnetic ring 402c-5 in drive is inwardly moved, and is driven
Set 401 is inhaled according to the magnetic force of part to be drawn, can be by the rotation of magnetic ring 402c-5 in rotation drive, therefore can be finely tuned slotting
First 403 with the docking angle of connector 402.When symmetrically arranged interior magnetic ring 402c-5 is moved closer to, monosymmetric conduction
Column 402c-2 gradually stretches out, and contradicts to guide surface 402e-1, plugging block 402e is supported and is opened, therefore conductive column 402c-2 and buckle block
402c-3 is synchronous to stretch out fixing sleeve 402b, and conductive column 402c-2, which is progressed into conductive sleeve 402d, realizes contact conducting, buckles block
Notch 402c-6 is exposed in 402c-3 stretching, and can be inserted by the plugging block 402e that conductive column 402c-2 is contradicted and magnetic drive rotates
When entering and limited in notch 402c-6, therefore cooperating completion, do not occur as long as plugging block 402e can be inserted into notch 402c-6
Rotation, can be constantly in the state of locking, to realize the conducting of plug 403 Yu connector 402 between plug 403 and connector 402
Connection.Otherwise when disassembly is desired, it is rotated backward by magnetic ring 402c-5 in magnetic drive, plugging block 402e leaves notch
402c-6 by the recovery elastic force of spring element 402c-4, therefore has the effect of resetting, to complete the mistake of entire installing and dismounting
Journey.
The inside of magnetic connector 400 is mobile to centre, then selects certain angle, realizes the connection of line and the phase of bayonet
Mutually occlusion, realizes wiring and fixed function, and the magnetic connector 400 proposed in above-described embodiment is not limited to power supply end
Son 205 go out for example, can also be replaced to the common plug-and-pull port of controller process of distributing electricity, in order to match electrical testing mistake
Convenient installation and removal in journey.
