Abstract

PURPOSE:To improve the operating efficiency of winding the end conductor of a winding in a motor by winding the end conductor of the winding at a terminal secured to the upper surface of the end of the winding of a stator, and then bending it to the side of a terminal base. CONSTITUTION:A terminal 5 on which the end conductor 4 of a winding is wound is secured by press-fitting or insert-molding to a terminal base body 1 fixed to the upper and side surfaces of the end 3 of the stator winding wound on a stator 2.

Thus, the operating efficiency of winding the end conductor of the winding at the terminal of the terminal base for treating the end of the winding of the stator is held preferably, and the size of the housing of a motor can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a terminal block for terminal processing of stator windings of an electric motor having metal housings.

Conventional technology In general, the terminals of the terminal block for stator winding terminal processing of electric motors are fixed components, and there is no structure that allows them to be moved or deformed even after the winding terminal wires are wrapped and electrically connected. In order to ensure a spatial distance between the terminal and the metal housing, a housing with a large axial dimension is used, or a very small terminal is used, which makes it difficult to wind the winding end wire. Therefore, there has been a need for a terminal block for stator winding end processing that can reduce the size of the housing and has good workability for winding winding end wires.

Conventionally, a terminal block for processing stator winding ends of this type of electric motor has a terminal fixed to the upper surface of a winding end 102 of a stator 101 by a method such as adhesive, as shown in FIGS. 4 and 6. Winding terminal wires 106 are wound around a plurality of L-shaped terminals 104 (107) fixed to the stand main body 103, and electrical connections are made by soldering or welding, and the terminals 104 (107) are fixed to the base body 103 and are configured in an L-shape.・It was incorporated into Uzing 106 and 109.

Problems to be Solved by the Invention In such a conventional configuration, as shown in FIG.
06, and by increasing the rising dimension A of the terminal 104 from the terminal block body 103, the axial inner dimension C of the housing is increased in order to ensure the spatial distance Bi from the housing 106. There was a problem in that it became large. Also, as shown in Figure 5, Noujing 10
If emphasis is placed on reducing the size of the terminal block 9, it is necessary to reduce the rising dimension Ei of the terminal 107 from the terminal block main body 110, which poses a problem in that the workability of winding the stator winding terminal wire 108 deteriorates. .

The present invention is intended to solve these problems, and aims to reduce the size of the motor housing and at the same time improve the workability of winding the winding end wires of the stator.

Means for Solving the Problem In order to solve this problem, the present invention provides a terminal block for winding terminal processing fixed to a part of the upper surface or side surface of the winding terminal of the stator by press-fitting or inserting the terminal block. It has a terminal fixed by molding etc., and the winding terminal wire is wound around this terminal.
・The terminal is bent to the terminal block side after electrical connection is made by a method such as bending.

With this configuration, when winding the terminal wire of the stator winding, the terminal stands up sufficiently from the terminal block body, and the winding work can be easily performed, and the winding terminal wire and the terminal can be easily wrapped. After electrical connection, by folding the terminals/pieces in close contact with the terminal block body, a spatial distance between the motor housing and the terminals can be ensured, and the housing can be made smaller at the same time.

EXAMPLE Hereinafter, an example of the present invention will be explained based on FIGS. 1 to 3.

In the figure, reference numeral 1 denotes a terminal block main body, which is fixed to the upper and side surfaces of the winding terminal 3 of the stator winding wound around the stator 2 with resin such as an adhesive, tying string, or the like. A terminal 5 around which a winding terminal wire 4 is wound is fixed to the terminal block main body 1 by press-fitting, insert molding, or the like. The winding terminal wire 4 is wound around the rising part of the terminal 6, and after an electrical connection with the terminal 6 is made by soldering, welding, etc., it is attached to the terminal block main body 1 side as shown in FIG. After being bent and molded with an insulating material 7, the stator 2 is press-fitted into the metal housing of the motor.

As described above, according to this embodiment, the housing 6 and the terminal 5
A spatial distance F is ensured between the housing 6 and the housing 6.
The axial dimension G of the terminal 6 is reduced, and the rising dimension H from the terminal block main body 1 around which the winding end wire 4 of the terminal 6 is wound can also be increased, thereby improving workability.

Effects of the Invention As is clear from the above description of the embodiments, the present invention maintains good workability for winding the winding end wires around the terminals of the terminal block for stator winding end processing, and reduces the housing dimensions of the motor. The effect of realizing miniaturization can also be obtained.
