Abstract

PURPOSE:To prevent the disconnection of wirings and an improper conduction by holding segments which are not directly contacted with a fusion-bonded portion of a winding by two pawl pieces to protect the bonded portion of the winding. CONSTITUTION:To wire an armature winding with a commutator, the winding portion 6a of a winding 6 is engaged in the state that the winding portion 6a is engaged over two pawl pieces 2, 2, the winding portion 6a between the pieces 2 and 2 is fusion-bonded, for example, by a supersonic wave generator, and the pieces 2, 2 are thereafter press-bonded to the periphery of a segment 1, and held. Thus, no disconnection of wirings or improper conduction might occur in the wirings of the armature winding to the commutator, and the wirings can be readily confirmed from the exterior.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a commutator connection method for IFT machine windings and an improvement of its commutator connection structure.

Conventionally, as a method for connecting 46 electric wires to a commutator, a claw piece is formed on each segment of the commutator, a part of the winding wire is hooked on the claw piece, and the claw piece is pushed down to connect the three wires with the claw piece. The pieces and segments are crimped 17 and fused, and the resistance heat generated at that time is used to burn out the wire insulation coating of the winding.
A method is used in which the winding is electrically connected to the commutator, but in this connection method, there is a risk of pressure deformation in the winding part and breakage if the wire is caught at the crimped part by the claw piece.
There are many disadvantages in manufacturing and performance for windings with small wire diameters and small commutators, and there are drawbacks that make it difficult to apply. In addition, in the connection structure using the above-mentioned wiring method, the contact conduction state between the winding portion and the segment is hidden by the claw piece, so the contact state cannot be confirmed from the outside. If it floats up, it has the disadvantage of poor conductivity.

This invention was made in order to eliminate the above-mentioned drawbacks, and is not limited by the wire diameter or the size of the commutator, and it is possible to control the condition of the conductive part where the winding contacts the segment. It is an object of the present invention to provide a method for connecting a commutator of an armature winding, which can be confirmed from the outside, and which does not cause a disconnection accident, and a commutator connecting structure thereof.

A commutator connection method for an armature winding according to the present invention includes forming a plurality of claws on each segment of a commutator, hooking a part of the winding to the plurality of claws, and connecting the winding between the claws. In addition, in the commutator connection structure for armature winding according to the present invention, a plurality of claw pieces are formed in each segment of the commutator, and the plurality of claw pieces are connected to the segments. It is characterized by a structure in which a part of the winding is hooked on the hook, and the winding part between the claw pieces is joined to the segment.

EMBODIMENT OF THE INVENTION Hereinafter, this invention will be explained in detail based on the drawing which showed an example of the embodiment.

As shown in FIGS. 1 and 2, the commutator used in this invention has two
Each claw piece (2) (2) is formed by, for example, a trimming process, and is bent in advance as shown in the dotted line. (3) is a molded synthetic resin insulating support.

The commutator constructed as described above is assembled into an armature as shown in FIGS. 3 and 4. (4) is the rotation axis, (5
) is iron core.

Therefore, in order to connect the armature winding to the commutator, as shown in FIG.
Hook the hook between the two claw pieces (2) (2) in a state where it is passed, and the winding part (6a) between the claw pieces (2) (2).
For example, by welding using an ultrasonic generator (not shown), the claw pieces (2) (2) are then welded to the segments (1).
Crimp and hold on the surface. (7) is a welded part.

To connect the terminal wires at the beginning and end of the winding to the commutator, first connect the terminal wires (6b) at the beginning of winding as shown in Figure 4.
is passed between both claw pieces (2) (2) and segment (1), one claw piece (2) is crimped and held on the segment, and then the claw pieces of each other segment are fixed by winding operation. The terminal wire (6C) at the end of the winding is passed through the claw piece (2) and held by crimping, and then both terminal wires (6C) are
b) (6c) and the claw piece (2) (2) are aligned parallel to each other and welded to the segment (1) using an ultrasonic generator. (8
) is the welded part.

According to the method for connecting a commutator of an armature winding described above, the following effects can be obtained.

(1) In order to secure the welded joints of the windings, the wire portions that are not in direct contact with the joints are held by two claws, so there is no risk of external force being applied directly to the joints.

(2) In the conventional wiring connection method, if the claw pieces lift up, poor continuity will occur, but according to the above method, the winding parts are joined by segment (K) welding, so there will be no continuity failure due to the influence of the claw pieces. Does not occur.

(3) Conventional nusing processing has limitations on the wire diameter of the windings and the size of the commutator, but according to the method described above, the range of use of ultra-fine wires and small commutators can be greatly expanded.

(4) Unlike the conventional 7-using process, only the parts that require bonding are spot bonded, so power consumption and equipment can be reduced.

(5) In terms of quality, it is easy to greatly reduce disconnections, poor continuity, etc. that occur during the wiring process, and the reliability of the wiring part can be greatly improved.

As described above, according to the present invention, there is provided a wiring method in which the armature winding is connected to the commutator without the risk of disconnection or poor conduction, and in which the wiring part can be easily confirmed from the outside. In addition, it is possible to greatly expand the range of application to the wire diameter of the winding and the size of the commutator.
