Problems solved by technology

[0011] In addition, since there is a certain degree of tolerance in the diameter of the winding wire, in the case where the first layer of winding wire is composed of a thin wire shape, the second layer of winding wire falls between the winding wires, the winding wire and the side wall of the bobbin. Between, there is a problem that the winding wire cannot be tightly wound due to the scattered

Embodiment Construction

[0035] Hereinafter, the electromagnetic clutch 10 of the present embodiment and its manufacturing method will be described with reference to the drawings. In the following description, the same reference numerals are assigned to the same parts, and overlapping descriptions are omitted. In the following description, directions of up, down, left, and right are used, but left and right are left and right when facing the winding direction, upper is radially outside of the bobbin 21 , and lower is radially inward of the bobbin 21 .

[0036] refer to figure 1 The schematic sectional view of the electromagnetic clutch 10 of this form is demonstrated. The electromagnetic clutch 10 mainly includes a rotor 11 , an armature 12 arranged above the rotor 11 , and a magnetic generating unit 20 (coil) built in the armature 12 .

[0037] The electromagnetic clutch 10 is installed, for example, between a compressor of an air conditioner (not shown) that cools and heats the interior of a vehic...

Abstract

An electromagnetic clutch and a manufacturing method thereof are provided, having a structure in which winding wires are wound around a bobbin in a tight and neat state. An electromagnetic clutch (10) of the present invention includes a rotor (11), an armature (12) arranged above the rotor (11), and a magnetic generating unit (20) built in the armature (12). Furthermore, the magnetism generating unit (20) includes a bobbin (21), a winding wire wound around the bobbin (21), and a ring (22) for accommodating the bobbin (21). Furthermore, the bobbin (21) has a cylindrical body part (30), a first flange part (31), a second flange part (32), a cutout (33) formed in the first flange part (31), An incomplete annular convex portion (34) protrudes outward in the radial direction from one end of the outer surface of the cylindrical portion (30).

Description

technical field [0001] The present invention relates to an electromagnetic clutch and a manufacturing method thereof, and more particularly to an electromagnetic clutch in which a winding wire is neatly wound around a bobbin and a manufacturing method thereof. Background technique [0002] The electromagnetic clutch is arranged between the air conditioner compressor and a power source such as an engine, and is a mechanical mechanism that mechanically and intermittently connects the compressor and the power source. This type of electromagnetic clutch mainly includes a rotor with built-in coils, an armature disposed on the side of the rotor, and a hub connecting the drive shaft and the armature plate. [0003] When power is transmitted from the power source to the compressor, power is supplied to a coil composed of a winding wire wound around a bobbin to generate magnetic force, and the armature is attracted to the side surface of the rotor by this magnetic force. Accordingly...
