Description

Coil of electromagnetic clutch and manufacturing method thereof {COIL AND IT'S MANUFACTURE METHOD OF ELECTRIC CLUTCH}

The present invention relates to a coil of an electromagnetic clutch and a method of manufacturing the same.

As is generally known, the electromagnetic clutch selectively interrupts the rotational force of the engine and transmits it to the compressor. In order to transmit the rotational force of the engine to the drive shaft of the compressor, a magnetic circuit is formed between the rotor and the disk by applying power to the coil. When the magnetic circuit is formed, the disk is attracted to the rotor to perform the rotational operation of the compressor.

As shown in FIGS. 1 to 3, the coil 1 of the conventional electromagnetic clutch is installed in the guide groove 4 of the rotor 3 supported by the bearing 2 in the front housing of the compressor. The coil (1) installed in the guide groove (4) is to be wound with a copper wire (5) of a predetermined length or more, and to fix the wound partial layer by a heat fusion method, and to fix the coil (1) to the housing (6) It is to be installed in the guide groove 4 of the rotor (3).

In order to fix the coil 1 by a thermal fusion method, the copper wire 5 in which the adhesive 7 is applied is wound when the copper wire 5 is wound by a self heat of the copper wire 5 when the copper wire 5 is wound over a predetermined length. The adhesive 6 may be applied to the outer circumference of the bundle of copper wires 5 after use or winding, and a high voltage is applied to the copper wires 5 while the adhesive 6 is applied to the copper wires 5. The coil (product) 1 is formed as the wound partial layer is integrated by fusion.

The coil manufacturing method of the above-described electronic clutch has a problem in that the manufacturing cost is increased due to excessive consumption of the copper wire 5 because the copper wire 5 is wound over a predetermined length and produced by applying a high voltage to the copper wire 5. There is this.

In addition, since the resistance of the copper wire 5 is wound in series, as the resistance thereof increases, the size of the coil (product) 1 may be increased, and the performance of the product 1 may be degraded.

(12) a third step (S3) applied by using a phenol resin, polyester, paraffin, polyesterol, insulating varnish, and the like, and the insulating material 12 fixed in the third step (S3) A fourth step S4 of forming a fusion layer 13 of polyamide on the outer circumference and a copper layer 11 of the same size in which the fusion layer 13 is formed through the fourth step S4. A fifth step (S5) of laminating and fusion bonding an appropriate number of layers, and processing the end of the copper layer 11 by a grinder or the like after the fifth step (S5). After be conductive to coupled the connector kit 14 will be made of a sixth step (S6) so that each copper layer (11) is connected in parallel.

The copper layer 11 formed through the first process S1 is formed in a ring shape and different in size from each other, and the separation of the copper layer 11 is connected to each copper layer 11. It is to be separated by applying a corrosion solution to the cutting, and by laminating the copper layer 11 of the same size formed by repeating the above process to obtain a thin coil body 15.

After the separation of the copper layer 11 is applied to the outer periphery of the copper layer 11 by applying an appropriate thickness to the insulating layer 12 so that the insulating function between each copper layer 11 is dried. The fusion layer 13 fixed to the outer circumferential surface of the insulation 12 may be integrally bonded in a state where each copper layer 11 is stacked, and the heating is performed after the copper layer 11 is laminated. When the heat is applied to the copper layer 11 using a group (not shown) or the like, the fusion layer 13 is melted, and when the heat of the heating machine is removed in a state where the melting of the fusion layer 13 is performed properly, The copper layer 11 is bonded by the bonding of the fusion layer 13.

The connector kit 14 used in the sixth process S6 is formed on both sides of the housing 16 and the housing 16 which are connected to the connector of the compressor to receive external power, and the copper layer 11 The guide hole 17 is formed to be divided into the copper layer 11 to be inserted independently to face the stack height, and installed in the bottom portion of the guide hole 17, and applied external power is applied to each copper layer ( 11) is composed of a terminal portion 18 is applied.

The laminate is applied to heat the fused layer 13 by applying heat to the laminated copper layer 11.

In this state, when the fusion layer 13 is melted on the surface of each copper layer 11, heat is removed. When the heat is removed, the fusion layer 13 is fixed and each copper layer 11 is bonded.
