Abstract
A bipolar AC contactor applicable for the single-phase electric equipment is equipped with an upper shell and a lower shell, a contact system comprising contact brackets, contacts and so on, and an electromagnetic system comprising a coil, a magnet yoke, a gag bit and so on. The contacts of the contact system consist of a double-pole main contact and a one-pole auxiliary contact. All inlet and outlet wires of the single-phase electric equipment can be controlled just with two pairs of normal-opening main contacts, or a power source can be switched by a single contactor with a pair of normally-opened main contacts and a pair of normally-closed main contacts. Self-locking or other controls of the contactors can be realized with the auxiliary contact. Moreover, connection-pegs for plug-connection are arranged at a joint of the main contact and a joint of the coil. The utility model is provided with a simple structure and a small dimension.
Description
One. technical field: the utility model relates to a kind of control apparatus, particularly a kind of A.C. contactor.
Two. background technology: at present, there are many single-phase electric devices often to use the three-pole AC contactor to realize circuit control, but the three-pole AC contactor is used for single-phase electric devices volume defective big and the difficult realization of power supply switching in the separate unit contactor is then arranged.
Three. summary of the invention: the technical problem that the utility model solves is that the contactor volume that use three-pole AC contactor control single-phase electric devices exists is big, and the separate unit contactor is difficult for the defective that the realization power supply switches.The technical solution of the utility model is: this contactor has adopted bipolar A.C. contactor structure, be provided with upper and lower casing, the contact system of forming by contact supporting and contact etc., with the electromagnetic system of being made up of coil, yoke, armature etc., the contact of its contact system is made up of two utmost point main contacts and a utmost point auxiliary contact.By adopting said structure, adopt two pairs often to open the turnover line that main contact can satisfy single-phase electric devices and all control, perhaps adopt a pair of main contact and a pair of normally closed main contact often opened, can realize the switching of power supply in the separate unit contactor, its auxiliary contact can be realized contactor self-locking or other control.The dipolar configuration of this contactor simplifies the structure than three-stage structure, has dwindled overall volume.
Four. description of drawings: accompanying drawing is the utility model structural representation.
Five. execution mode: with reference to the accompanying drawings, the utility model is provided with upper shell 1 and lower house 2.The contact system that contact supporting 3 and main and auxiliary contact etc. are formed is housed in the upper shell 1, is connected with connection-peg 4 with screw in main contact wiring place, for connecting main circuit with the standard connection-peg, when without connection-peg 4, the direct wiring of available screw.The electromagnetic system that coil, yoke, armature etc. are formed is housed in the lower house 2,, is connected with connection-peg 5,, when without connection-peg 5, can directly connect with screw for the wiring of standard connection-peg with screw at the winding wiring place.
Claims (2)
1. bipolar A.C. contactor, be provided with upper and lower casing, contact system of being made up of contact supporting and contact etc. and the electromagnetic system of being made up of coil, yoke, armature etc., it is characterized in that: the contact of contact system is made up of two utmost point main contacts and a utmost point auxiliary contact.
2. bipolar A.C. contactor according to claim 1 is characterized in that: main contact wiring place at upper shell is connected with connection-peg (4) with screw, is connected with connection-peg (5) at the winding wiring place of lower house with screw.
