The present invention relates to a connector mounting structure of an electromagnetic clutch for a compressor, and more particularly, to reduce the weight of the connector bracket to which the connector of the field coil assembly is coupled by resin molding, and to insert the connector bracket into the compressor to mount the component and The present invention relates to a connector mounting structure of an electronic clutch for a compressor, in which an assembly process is reduced to improve assemblability, productivity, and cost.

In general, a compressor for an air conditioner of a vehicle is a device that compresses a refrigerant supplied from an evaporator and sends it to a condenser while driving by power of an engine. The compressor is selectively received and driven by an electric clutch.

Thus, the electromagnetic clutch for selectively transmitting the power of the engine to the compressor according to whether the power is applied will be described with reference to FIG. 1.

As shown in FIG. 1, the electromagnetic clutch 20 is rotatably installed in the housing 11 of the compressor 10 via a bearing 23, and the engine crank shaft and the drive belt (not shown). A pulley 24 connected to the rotor 25, a rotor 25 embedded in the pulley 24 and having a friction surface 25a on one side thereof, and a suction magnetic flux built in the rotor 25 according to application of power. It consists of the field coil assembly 21 which has the field coil 21a to generate | occur | produce.

The electromagnetic clutch 20 formed as described above is connected to the compressor 10 so as to transmit power, and the connection structure includes a hub 13 coupled to the drive shaft 12 of the compressor 10, and the hub 13. It consists of a disk 14 coupled to interlock.

The disk 14 is attracted to the friction surface 25a of the rotor 25 by the suction magnetic flux generated in the field coil 21a to transfer the rotational force of the pulley 24 to the drive shaft 12 of the compressor 10. To pass.

According to this configuration, when power is applied to the field coil assembly 21 of the electromagnetic clutch 20, the disk 14 is pulled 24 by the suction flux of the field coil 21a generated by the magnetic induction of the electromagnetic coil. By moving to the rotor 25 which is rotated by the rotor and attracted to the friction surface 25a of the rotor 25, the power of the engine transmitted to the pulley 24 is transmitted through the disk 14 and the hub 13 through the compressor. It is transmitted to the drive shaft 12 of (10).

When the power applied to the field coil assembly 21 is cut off, the disk 14 of the compressor 10 adsorbed and the friction surface 25a of the rotor 25 are separated from each other to be spaced apart from each other. Power of the engine transmitted to the drive shaft 12 is cut off.

As such, the electromagnetic clutch 20 for the compressor transmits or blocks the power of the engine to the compressor 10 depending on whether power is applied.
