Preferably, described contact module is made up of one or more main contact submodules and auxiliary contact submodule, and the main contact submodule each has snap joint with the auxiliary contact submodule and is connected with fast interface.

Preferably, described contact module is made up of one or more mixed type contact submodules, and mixed type contact submodule is made of jointly main contact and auxiliary contact, and a shared snap joint is connected with fast interface main contact with auxiliary contact.

Preferably, described contact module is made up of one or more mixed type contact submodules and one or more main contact submodule.

Preferably, described main contact submodule is provided with arc-control device.

Preferably, have rubber seal between electromagnetic contactor housing and the contact submodule, enter electromagnetic contactor housing and contact module inside to avoid dust and steam.

Modular electromagnetic contactor provided by the utility model is because with electromagnetic assembly and contact assembly modularization, between module, adopted the method for quick connection, make contact module fast assembling-disassembling and maintenance all be very easy to, and, improved useful life to a great extent again owing to adopted the structure of sealing.

Embodiment

Fig. 1 is the schematic diagram of modular electromagnetic contactor first embodiment; Fig. 2 is the schematic diagram after modular electromagnetic contactor first embodiment resolves into two big modules; Fig. 3 is the schematic diagram after modular electromagnetic contactor first embodiment further decomposes.

As Fig. 1, Fig. 2, shown in Figure 3, present embodiment is formed contact module 1 by four mixed type contact submodules 3, electromagnetic contactor housing 12, solenoid 7, static iron core 8, moving iron core 6, resetting means 10 and the electromagnetic attraction module 2 that is fixed on fast interface module 11 compositions on the moving iron core 6; Described four mixed type contact submodules all respectively have snap joint 4, and the sub-fast interface 5 of each and the fast interface module 11 of mating is connected; Mixed type contact submodule 3 is made of jointly main contact and auxiliary contact, and main contact is connected with corresponding sub-fast interface with the shared snap joint of auxiliary contact;

During solenoid 7 energisings, attract moving iron core 6 to static iron core 8 motions, because moving iron core 6 and fast interface module 11 are synchronized with the movement, the sub-interface 5 of fast interface module 11 drives each self-corresponding sub-snap joint campaign, make the contact action in the contact submodule, finish the function of connecting load; During solenoid 7 dead electricity, moving iron core resets under the effect of resetting means 10, makes the contact action in the contact submodule, finishes the function of disconnecting consumers.

Have rubber ring 9 between electromagnetic contactor housing 12 and each the contact submodule 3, enter electromagnetic contactor housing and contact submodule inside to avoid dust and steam.
