Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric motor, and more particularly to a holder for a lead wire of a stator winding.

[0002]

2. Description of the Related Art Conventionally, a lead wire of a stator winding in an electric motor has a lead wire 3 of the stator winding supported by a lead rubber 4 provided on one bracket B2 as shown in FIG. , Take out the lead wire to the outside of the bracket, and use the other bracket A
It was fitted with 1. In this case, it is necessary to perform the two steps of mounting the lead-out rubber on one bracket B and inserting the lead-out wire into the through-hole 4a of the same lead-out rubber, resulting in poor work efficiency.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems of the prior art. It is possible to easily take out the lead wire of a stator winding of an electric motor to the outside, and It is an object of the present invention to provide an electric motor with improved installation work efficiency.

[0004]

In order to achieve the above-mentioned object, brackets are press-fitted on both sides of a stator, and the side surfaces of one bracket project in the outer circumferential direction along the longitudinal direction and face the other bracket. A housing rubber having an opening formed in the surface is integrally formed, and a lead rubber with a through hole formed in the center of the housing corresponding to the housing portion It is characterized in that it is inserted into a through hole of rubber and attached to the storage portion, and the one bracket is fitted to the other bracket. Further, it is characterized in that the shape of the storage portion of the bracket is substantially semi-cylindrical. Alternatively, the storage portion of the bracket is formed into a substantially box shape. Further, a locking piece corresponding to the side surface of the stator is projected to the stator winding side of the output rubber at a substantially right angle, and the locking piece is locked to the stator. Alternatively, the depth of the accommodating portion is formed to be substantially the same as the longitudinal dimension of the output rubber.

[0005]

According to the above structure, the brackets are press-fitted on both sides of the stator, and the openings formed on the side surfaces of one of the brackets projecting in the outer circumferential direction along the longitudinal direction and facing the other bracket. A housing rubber is integrally formed, and a lead rubber having a shape corresponding to the housing and having a through hole formed in the center thereof is inserted in advance into the lead rubber of the stator winding into the through hole of the rubber outlet. Installed in the storage part, and the one bracket is fitted to the other, and the storage part of the bracket has a substantially semi-cylindrical shape, or the storage part of the bracket has a substantially box shape, Further, a locking piece corresponding to the side surface of the stator is projected to the stator winding side of the outlet rubber at a substantially right angle, and the locking piece is locked to the stator, or the depth of the storage portion is set to the mouth. Make sure that the length of the rubber is the same as the length of the rubber. Therefore, it is possible to pass the lead wire through the through hole of the lead rubber in advance at the time of assembly, pass through the protective tube for the lead wire, and connect a connector larger than the through hole to the tip of the lead rubber. .

Embodiments of the present invention will be described in detail with reference to the accompanying drawings. Here, the same reference numerals are used for the same parts as the conventional ones. FIG. 1 is a sectional view of an embodiment of an electric motor according to the present invention, and FIG. 2 is a side view thereof. FIG. 3 is an exploded perspective view of the main part of FIG. The electric motor according to the present invention has a structure in which the bracket A1 and the bracket B2 are press-fitted on both sides of the stator. First, the storage portion 5 for fixing the output rubber 4 is integrally provided on the side surface of the bracket A. Here, the shape of the accommodating portion projects in the outer peripheral direction along the longitudinal direction of the bracket A, and forms an opening 5a on the surface facing the bracket B. On the other hand, the output rubber is substantially cylindrical and has a through hole 4a formed at the center thereof. Then, after inserting the lead wire 3 of the stator winding into the through hole provided at the center of the lead rubber in advance,
The rubber outlet is fixed to the storage portion. Further, the rubber outlet is taken out from the opening 5a of the storage portion formed on the side surface of the bracket A. Here, the bracket A is fitted with the other bracket B.

On the other hand, in the above embodiment, the shape of the accommodating portion is substantially semicylindrical and the shape of the opening is substantially semicircular.
As shown in FIG. 4, the shape of the storage portion may be substantially box-shaped, and the shape of the opening may be substantially rectangular. Further, a locking piece 4b that locks with the side surface of the stator may protrude toward the stator winding side in a substantially perpendicular direction to lock the stator and the rubber outlet. Further, the depth dimension of the storage section may be made substantially the same as the dimension of the output rubber in the longitudinal direction to prevent the movement of the output rubber.

[0008]

As described above, in the present invention, the brackets are press-fitted on both sides of the stator, and are formed on the side surface of one of the brackets so as to project in the outer circumferential direction along the longitudinal direction and to face the other bracket. A housing with an open opening is integrally formed, and a lead rubber with a through hole formed in the center of the housing in a shape corresponding to the housing Insert it into the hole and attach it to the storage part,
One of the brackets is fitted to the other, and the shape of the storage portion of the bracket is substantially semi-cylindrical, or the shape of the storage portion of the bracket is substantially box-shaped, and the fixing of the output rubber is further performed. An engaging piece corresponding to the side surface of the stator is projected to the child winding side at a substantially right angle, and the engaging piece is engaged with the stator, or the depth of the accommodating portion is set to the longitudinal dimension of the output rubber. Since the wires are formed to be almost the same, the lead wire is previously passed through the through hole of the lead rubber during assembly, the protective tube for the lead wire is passed through, and the tip of the lead rubber is larger than the through hole. It is possible to connect the connector. As a result,
It is possible to easily take out the lead wire of the stator winding of the motor to the outside, improve the efficiency of the work of attaching the lead rubber, improve the reliability, and improve the efficiency of the work of attaching in the manufacturing process. it can.
