As described in Japanese Utility Model Application Publication No. 126685 and Japanese Utility Model Application No. 62-38051, insulating paper is formed into a bag shape by winding one insulating film multiple times, and each bag portion has a plurality of connection parts. There is one that stores. in this case,
Since the insulating paper becomes a single component, it is easier to insert the connection part, but the insulating paper still has to be temporarily fixed to the coil end with a binding paper, which makes the installation work worse, and if it is not fixed with a binding thread. However, there was a problem in that the springback of the coil caused it to pop out from between the windings, posing a problem in subsequent work.

た絶縁紙である。 Reference numeral 1 denotes a stator of an electric motor, in which a main winding 3 and an auxiliary winding 4 are wound around slots (not shown) of a stator core 2. Reference numerals 5 and 6 are connecting portions between lead wires 7 and 8 drawn out from the windings 3 and 4 and lead wires 9 and 10 connected to the power supply circuit. This connecting portion is connected to each bag portion 12 of the bag-shaped insulating paper 11, which will be described later.
13, it is inserted between the coil ends 3a and 4a of both the main winding 3 and the auxiliary winding 4. Reference numeral 11 is an insulating paper formed by winding a rectangular insulating film two and a half times in the longitudinal direction, and then thermally welding one side 15 excluding the terminal end 14.

ンドへの装着作業性を向上できる。 In the insulating paper for the connection part of the electric motor configured in this way, the terminal end 14 of the insulating film is not welded and becomes a free end, so this insulating paper is used to connect the windings 3 and 4.
When inserted between them, the elastic force of the terminal end portion 14 acts between the coil ends 3a and 4a, and the insulating paper 11 is reliably fixed between the coil ends 3a and 4a. Further, since two large and small bag portions 12 and 13 are formed inside the insulating paper 11 by winding it two and a half times, the operation of inserting each of the connecting portions 5 and 6 can be performed smoothly. As a result, the insulating paper 11 can be fixed in the valley between the coil ends 3a and 4a without using binding thread for temporary fixation, reducing the number of parts and improving the workability of inserting the connection part and attaching it to the coil end. Work efficiency can be improved.
