Description

AC contactor

Technical Field

The utility model relates to an electrical apparatus field, concretely relates to ac contactor.

Background

The AC contactor is widely applied to low-voltage circuits, is an industrial necessity with safe use, convenient control, large quantity and wide range, and has the working principle that when an electromagnetic coil of the contactor is not electrified, the main contact keeps an off position by the counter-acting force of a spring and the dead weight of an armature core. When the electromagnetic coil is connected with a control voltage (generally a rated voltage) through a control circuit, the armature is attracted to the static iron core by the electromagnetic force against the counterforce of the spring to drive the main contact to be closed, the circuit is connected, and the auxiliary contact acts along with the main contact. Existing ac contactors are widely used as power switching and control circuits. It utilizes the contact to open and close the circuit, generally includes four parts: 1. the electromagnetic system comprises an attraction coil, a movable iron core and a static iron core; 2. the contact system comprises three groups of main contacts and one to two groups of normally open and normally closed auxiliary contacts, and the contact system is connected with the movable iron core to be linked with the movable iron core; 3. insulating casing, accessories, various springs, transmission mechanism, short-circuit ring, binding post, etc.

The pole core that it adopted the integral type usually and move the iron core and link mutually thereby drive the main contact and the auxiliary contact of contact system, close, but in actual production process, because the application scene is different, only need main contact a bit, need multiunit auxiliary contact again a bit, consequently current manufacture factory all opens multiunit mould, produces different contactors. And because adopt behind the integral type pole core, the pole core passes the base setting, one end is located the base below and is drawn with moving the iron core earlier and link to each other, the mid portion is in main contact at the base and links to each other, the other end passes the base and links to each other with auxiliary contact, it is very difficult when actual assembly, generally need reverse installation, and ac contactor is heavier and the holding causes spare part to lose, also comparatively difficult with base cooperation department, current way usually is the volume that increases the product, reduce the precision and the assembly degree of difficulty of product, but will make the product bulky like this, the materials are many, high cost, and the pole core rocks easily when moving, influence the branch of contact system, close. In addition, the existing different main contacts and the existing different auxiliary contacts are separated by partition plates, but the creepage distance is increased by increasing the height of a product between the main contacts and the auxiliary contacts, so that certain potential safety hazards exist. In the existing alternating current contactor, a lug plate and a coil rack are usually fixed in a clamping mode, but the inferior style and model cannot be adapted usually, so that the production cost of the product is higher. And different ac contactor usually need link together and use, and current practice is usually to increase the connecting piece on the casing, and the connecting piece is connected with the casing through the screw for it is more troublesome when different contactors connect, wastes time and energy.
