Description

  The present invention relates to a field assembly used for a blower motor for a vacuum cleaner.

  When the blower motor for a vacuum cleaner is incorporated in the main body of the vacuum cleaner, a protector as an overload protection device and a condenser for preventing noise are attached. However, the work for attaching the protector and the noise prevention condenser to the motor is necessary, and it is necessary to secure the space in the cleaner body. Therefore, there are problems in terms of workability and cost, such as complicated wiring of the wiring in the main body.

  As an improvement plan of the conventional protector and capacitor holding, a protector and a noise prevention capacitor holding case are attached to the outer peripheral portion of the motor case and disposed therein.

5 and 6, 1 is a motor case, 2 is a protector / condenser storage case, 3 is a protector, and 4 is a noise prevention capacitor, which is held and fixed on the outer periphery of the motor case 1. (For example, see Patent Document 1)
Japanese Utility Model Publication No. 7-32926

  However, in the conventional configuration, in order to attach the protector / capacitor storage case 2 to the outer periphery of the motor case 1, it is necessary to secure a storage space in the main body. Further, since the protector 3 is attached to the outside of the motor case 1, there is a problem that the temperature rise detection of the motor winding is poor.

  In view of the above problems, the present invention is characterized in that a protector and a noise prevention capacitor can be attached to the side surface of the field core. In addition, the shape of the holding and fixing has been devised so that it can be attached to either a protector or a condenser on one winding frame, corresponding to the split iron core. Specifically, the holding part, the supporting part, and the bag part are configured on two winding frames attached to both end faces of the field core.

  With this configuration, the protector and the capacitor can be stored in the motor, and there is no need to secure a space when the main body is assembled. Further, in the present invention, particularly in the case of a split core type, it is possible to easily attach either a protector or a noise prevention capacitor with one type of reel shape.

  In the field assembly of the present invention, by forming a square holding part for a noise prevention capacitor and a bag part for holding a protector on a winding frame, only a noise prevention capacitor, a protector only, a protector, and a protector It is possible to deal with three types of mounting patterns for noise prevention capacitors.

  By attaching the protector and the noise prevention condenser to the field assembly, it is not necessary to attach the protector and condenser when assembling the motor in the cleaner body, and the assemblability is good.

  Embodiments of the present invention will be described below with reference to the drawings.

  By providing a protector and a noise prevention capacitor holding part on the side surface of the field core, it is easy to store in the motor case and achieves compactness.

  FIG. 1 is a plan view of an embodiment of the present invention, in which 5a and 5b are field iron cores, 6a and 6b are winding frames, 7 are field windings, 3 is a protector, 4 is a noise prevention capacitor, and 8a. 8b, 8c and 8d are connection lines, 9a and 9b are power supply terminals, 10a and 10b are noise prevention capacitor holding and fixing support portions, 11a and 11b are noise prevention capacitor lead wire fixing and protector fixing claws, and 12 is a protector holding portion. It is a bag part. 2 and 3 are side views of an embodiment of the present invention, FIG. 4 is a side view showing a split core structure, and symbols are the same as those in FIG.

  In the case of an integral type iron core, the attachment holding part of the protector 3 and the noise prevention capacitor | condenser 4 can be provided separately on a winding frame.

  However, in the case of a split iron core, it is common to form the winding frame shape with one type, and in that case, it is important that either the protector 3 or the noise prevention capacitor 4 is attached. In the present invention, the protector 3 is formed by forming the capacitor holding and fixing support portions 10a and 10b, the capacitor lead wire fixing portion / protector fixing claw portions 11a and 11b, and the protector holding bag portion 12 on a part of the reels 6a and 6b. Both of the noise prevention capacitors 4 can be held and fixed.

  In the state where the divided iron cores 5a and 5b are press-fitted and fixed, the protector 3 can be attached to one side and the noise prevention capacitor 4 can be simultaneously attached to the other side.

  The field assembly of the present invention is useful as a vacuum cleaner motor protector and a compact storage method for a condenser.
