Abstract

PURPOSE:To reduce the working number for connecting and securing lead wires by providing notches at a stator core in the longitudinal direction, interposing lead connecting wires between divided upper and lower insulating plates, engaging them fixedly with a bracket. CONSTITUTION:Dovetail-shaped notches are formed on a stator core along the longitudinal direction, and lower insulating plates 9 which have grooves of the same number as lead wires are respectively inserted into the notces. Connectors connected by soldering lead wires and windings are placed in the respective groove of the plates 9, and an upper insulating plate 10 formed in the same shape as the plates 9 are coated on the connectors 11. The plates 9, 10 are moved along the outer periphery of the stator core, press-fitted to a bracket, and engaged with each other fixedly. Thus, a tube to be coated on the connectors 11 and primary insulating paper can be eliminated to facilitate the works.

First, connect the Hiji Rubber (5), the winding (1), and the lead wire (3) to the lead wire (3) whose tip has been stripped to connect with the winding (1'l). Pass the tube (6) to protect the lead wire (3).Next, connect the winding (1) and the lead wire (3) by soldering the cored part of the tip, and pass it through the lead wire (3) in advance. By moving the tube (6), the soldering part is protected, and the protection part is placed on the insulating paper (8) laid between the lead wire (3) and the winding wire (1). put.

Furthermore, with the binding thread (7), the lead line (3), the protection part (6),
Fix the insulating paper (8) to the winding fl).

Press the bracket (4) around the outer periphery of the stator (2) of the finished wire-wound product completed in the above procedure, and insert the Hiji rubber (5) into the window hole (4-1) of the bracket (4). By inserting the lead wire (3), the lead wire (3) is pulled out from the winding wire (1).

The conventional specifications had the drawback that it took a lot of time to connect the winding (1) and the lead wire (3) and to insert the Hiji rubber (5) into the window hole of the bracket (4).

Problems to be Solved by the Invention The object of the present invention is to reduce the number of man-hours required for connecting the winding wire and the lead wire and for inserting the bracket cutout of the Hide Rubber into the section.

Means for Solving the Problems The present invention provides a dovetail-shaped notch in the longitudinal direction on the surface of the stator core, and solders the cored parts at the ends of the windings and lead wires. a lower insulating plate having a rectangular corrugated band shape in cross section is inserted into the notch, the lower insulating plate is provided with the same number of grooves as the lead wires, and the connecting part is placed in the groove. Then, an upper insulating plate having the same shape as the lower insulating plate is placed over the connecting portion, and the lower and upper insulating plates are fitted together by compressing a bracket along the outer layer of the stator core. Fix and connect the connection part.

Function The present invention eliminates the need for tube threading work, eliminates the use of insulating paper under the lead wire, eliminates the need for tying strings, and eliminates the need for threading the tube.
It is possible to eliminate the steps involved, and furthermore, by adjusting the height and width of the grooves of the lower insulating plate and the upper insulating plate, the insulation distance between the connecting parts of the lead wire and the winding wire can be secured.

The lower insulating plate (9) and the upper insulating plate 00) are provided with the same number of grooves as the number of guide lines (3), and the bottom of the lower insulating plate groove (9) is provided with a fourth groove.
As shown in the figure, it has an R portion that is slightly larger than the outer diameter of the lead wire (3). The lead wire (3), the winding wire (1), and the connecting portion between the lead wire and the winding are connected to the R of the groove (!l-1) of the lower insulating plate (9).
Then, the grooves of the upper insulating plate 00) and the grooves of the lower insulating plate (9) are fitted to complete the connection work.

Effects of the Invention According to the present invention, it is possible to eliminate the need for threading the tube (6), the use of insulating paper (8) under the lead wire, and the use of tying thread (7) in the work of connecting the lead wire and the winding wire. This greatly reduces the number of man-hours required for winding. Further, by adjusting the groove height and width of the lower insulating plate (9) and the upper insulating plate θO), it is possible to ensure the insulation distance between the connecting portions of the lead wire and the winding.
