Wherein, electromagnet can be sucked type electromagnet or cylindricality electromagnet or push-pull electromagnet or towed electromagnet etc.
Latching device has snap close and the lock pin of mutual correspondence, and snap close is arranged on the travel(l)ing rest, and lock pin is arranged on the dropout armature, and dropout armature is arranged on the bearing pin, is provided with stage clip between dropout armature and the base, be provided with release magnet corresponding with dropout armature.
Equally, release magnet also can be sucked type electromagnet, cylindricality electromagnet, push-pull electromagnet or towed electromagnet etc., can and moving crane span structure and base between electromagnet identical or different, not simultaneously, form the hybrid combining behaviour in service.
Release magnet can be horizontally disposed with, and is fixed on the corresponding snap close base that arranges.Release magnet also can vertically arrange, and sets up the turnover pressing plate on the dropout armature, and the turnover pressing plate is corresponding with release magnet, and release magnet is fixed on the snap close base.
Base and snap close base can be fixed as one.
The present invention compared with prior art has following beneficial effect:
The present invention is simple and compact for structure, rationally, sucked type electromagnet or cylindricality electromagnet or push-pull electromagnet or towed electromagnet have been selected on the one hand, greatly dwindled volume, improved performance, on the other hand latching device is installed in the middle part between moving crane span structure and the base, form the lock catch-type structure, the pressure that has guaranteed three contacts is even, avoided the inclined to one side phase problem of side snap close (three contact pressure differences), the contactor performance is improved greatly, and because electric on off mechanism combines mechanical caging, working stability, dependable performance, the operating state that has thoroughly solved pure electromagnetism on off mechanism is subjected to voltage ripple of power network to affect the defective of existence: the voltage height easily burn solenoid; Voltage is low easily to be kept incessantly, also can cause burning contact because of the contact pressure reduction simultaneously.

Embodiment
The invention will be further described in conjunction with above-described embodiment accompanying drawing.
As depicted in figs. 1 and 2, central-latch type electromagnetic direct-running alternating-current contactor of the present invention, the moving of mutual correspondence arranged, fixed contact 1-1,1-2, moving contact 1-1 is installed on the travel(l)ing rest 1-4, fixed contact 1-2 is fixed on the fixed mount 1-3, fixed mount 1-3 is fixed on the base 1-8, the lower end of its travel(l)ing rest 1-4 is fixed with adhesive armature 1-5, be provided with side by side between adhesive armature 1-5 and the base 1-8, be fixed on two electromagnet on the base---adhesive electromagnet 2-8, be provided with latching device 1-7 between two adhesive electromagnet, the back-moving spring 1-6 among the latching device 1-7 is for resetting that travel(l)ing rest 1-4 moves.
Such as Fig. 3, Fig. 4 and shown in Figure 5, latching device has snap close 2-2 and the lock pin 2-1 of mutual correspondence, snap close 2-2 is arranged on the travel(l)ing rest 1-4, lock pin 2-1 is arranged on the dropout armature 2-4, and dropout armature 2-4 is arranged on the bearing pin 2-3, is provided with stage clip 2-5 between dropout armature 2-4 and the base 1-8, be provided with release magnet 2-6 corresponding with dropout armature 2-4, release magnet 2-6 is horizontally disposed with, and is fixed on the corresponding snap close base 2-7 that arranges, and base 1-8 and snap close base 2-7 are fixed as one.
Adhesive electromagnet wherein can be that sucked type electromagnet, cylindricality electromagnet, push-pull electromagnet or towed electromagnet let alone one, release magnet also can be that sucked type electromagnet, cylindricality electromagnet, push-pull electromagnet or towed electromagnet let alone one, can and adhesive armature 1-5 and base 1-8 between the adhesive electromagnet identical or different.
Operation principle:
During free state, moving contact 1-1 and fixed contact 1-2 are in released state under the effect of back-moving spring 1-6;
During adhesive, adhesive electromagnet 2-8 powers up, and adhesive armature 1-5 is under the electromagnetic force of adhesive electromagnet 2-8, and drive snap close 2-2, travel(l)ing rest 1-4, moving contact 1-1 move downward.When moving contact 1-1 and fixed contact 1-2 closure, snap close 2-2 is tangled by lock pin 2-1, and adhesive electromagnet 2-8 stops power supply, and moving contact 1-1 and fixed contact 1-2 still remain closed.
During dropout, power up the generation electromagnetic force for release magnet 2-6, dropout armature 2-4 is inhaled to move by electromagnetic force and rotates around bearing pin 2-3, compression press spring 2-5, after dropout armature 2-4 moved, lock pin 2-1 discharged the locking to snap close 2-2, and release magnet 2-6 stops power supply, snap close 2-2, adhesive armature 1-5, travel(l)ing rest 1-4, moving contact 1-1 pop up under the effect of back-moving spring 1-6, and moving contact 1-1 separates with fixed contact 1-2.
