Background technology
Existing three-phase dc contactor, auxiliary contact mostly use lead-out wire directly to receive exit, in the situation that auxiliary contact are less, use more for convenience.But more when auxiliary contact, or auxiliary contact exist dynamic circuit connector to close when conversion with quiet, and exit wiring increases thereupon, make product use and process of the test in lead-out wire there is crossover phenomenon, to product use and test has brought inconvenience.Simultaneously, existing contactor load is larger, the exit of auxiliary contact is all the mode of connection that adopts bolt, nut, when auxiliary contact are more, the volume and weight of whole product will increase, cause using inconvenience at numerous areas, meanwhile, existing three-phase dc contactor can not be with computer and some smart machines directly to fetching detection system.
Summary of the invention
The purpose of this utility model is: a kind of three-phase dc contactor with intelligent interface is provided, solve existing three-phase dc contactor auxiliary contact when more, there is crossover phenomenon in lead-out wire, and the existing contactor volume and weight problem that all large and this three-phase dc contactor can not directly dock with computer and some smart machines.
The technical solution of the utility model: a kind of three-phase dc contactor with intelligent interface, include mounting panel, circuit board is installed on mounting panel, mounting panel below is armature, armature outside is magnetic circuit part, on circuit board, be provided with auxiliary contact, the exit of auxiliary contact and magnetic circuit part is connected on circuit board, by wire, is connected on connector and output.
The above-mentioned three-phase dc contactor with intelligent interface, described armature inside is penetrated with drive link, on drive link, cover has main stage clip, drive link one end face contacts with pushing block, between described magnetic circuit part and pushing block, magnetic conductor is installed, pushing block below is pedestal, static contact spring piece is installed on pedestal, pull bar is contained on pushing block through pedestal, movable contact spring is housed on pull bar, nut, on movable contact spring, be provided with main contacts, lower encioser, outer cover is arranged on pedestal two ends, pushing piece is installed on the drive link other end and locks with locking nut, upper encloser covers on circuit board, on circuit board, be also provided with and start contact.
The above-mentioned three-phase dc contactor with intelligent interface, isolates with the arc wall on pedestal between described main contacts.
The beneficial effects of the utility model: compared with prior art, the utlity model has following characteristics:
1, change contactor auxiliary contact exit and adopted bolt in the past, the mode that nut is connected with coil exit, now the exit of auxiliary contact and coil is integrated into attachment unit interface terminal by circuit board, from connector port, draw in the lump, can directly dock with computer and some smart machines simultaneously.And due to the mode that adopts connector to replace bolt, nut to connect, the volume and weight of product is all significantly declined.
2, pedestal coordinates with the monnolithic case of product, and main contacts part is directly connected with pedestal, adopts the arc wall on pedestal to separate between main contacts, has avoided the impact of arc erosion between contact sets and group, has improved the insulation property of product.
3, wiring is more convenient, can directly carry out plug-in by connector port and connects and disconnect.
