Abstract

PURPOSE:To eliminate fixing work of a connecting conductor after it is connected, by connecting a both pole coil with an insulating conductor which can be plastically deformed. CONSTITUTION:Both the ends of a coil 4 composing a winding are inserted into a connecting unit 3 set on a terminal plate 2. After that, an enameled wire 8 is prepared, and the one end is inserted into the arbitrary connecting unit 3 and is extended on the bound coils 4, and the other and is inserted into the connecting unit 3 of an antipole. After that, a terminal 5 is inserted into the connecting unit 3, and the coil 4 and the enameled wire 8 are conducted with each other. The terminal 5 has a groove 10 which is longer in the inserted direction and has a width smaller than the outer diameter of the coil 4 and the enameled wire 8, and insulating film is peeled off by the terminal 5 when it is inserted into the connecting unit 3, and as a result, via the terminal 5, the coil 4 and the enameled wire 8 are conducted with each other. As a result, workability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a motor stator that connects bipolar coils.

[Background of the invention]

In a typical electric motor stator, power is supplied to the coil by connecting elastic lead wires to both ends of the coil.

Conventionally, in a stator that automatically winds wires, as shown in Figs. The coil 4 was made conductive ', π. However, in this method, it is necessary to fix the lead a6 in an appropriate position using the eastern wire band 9 or hemp thread in order to improve the workability of assembling it into the product or to prevent contact with the rotor. The drawback was that it had poor workability and was not compatible with mechanization.

In the same figure, 3 indicates a connecting body.

[Purpose of the invention]

An object of the present invention is to provide a connection structure for bipolar coils of a stator, which overcomes the drawbacks of the prior art described above, improves work efficiency, and makes it possible to respond to mechanization.

[Summary of the invention]

The present invention focuses on the fact that the terminals attached to both ends of the coil constituting the winding are attached to two electric wires at the same time, and uses a plastically deformable conducting wire, such as an enameled wire, as a relay member of the bipolar fill. In order to mechanize the work, we devised the relationship between the terminal board, terminal, coil, and enameled wire, and
Embodiment of the Invention An embodiment of the present invention is shown in FIGS. 1 to 4.

In the figure, 1 is a stator core, 2 is a terminal plate installed on the end face of the stator core 1, 3 is a connection body placed on the terminal plate 2, 4 is a coil wound around the stator 1, and 5 is a terminal plate installed on the end face of the stator core 1. are terminals located inside the connecting body 3 and attached to both ends of the coil 4. 6 is a lead wire, 7 is a terminal attached to the lead wire 60 wire core, and 8 is a plastically deformable insulated conductive wire made of an enameled wire. S indicates the entire motor stator.

The coil ends are connected as follows. Both ends of the coil 4 constituting the winding are inserted into the connecting body 3 placed on the terminal board 2, and then an enameled wire 8 is prepared and one end is inserted into any connecting body 3 to form a bundle of the coils 4. Kamizen Hasase,
After inserting the wire into the connecting body 3 of the opposite electrode, inserting the terminal 5 into the connecting body 3 and making the coil 4 and the enameled wire 8 conductive.
The enameled wire 8 acts as a relay member for the bipolar coils 4.

The terminal 5 has a groove 10 which is long in the insertion direction and narrower than the outer diameter of the coil 4 and the enameled wire 8, and the insulation coating is peeled off by the terminal 5 when inserted into the connecting body 3. Thus, the coil 4 and the enameled wire 8 are electrically connected through the terminal 5.

Since the coil 4 is usually made of enamelled wire that can be plastically deformed, one end of the coil 4 at one pole is inserted into the connecting body 3 of the opposite pole and connected directly to the coil 4 of the opposite pole through the terminal 5. Alternatively, there is no need to prepare an enamelled wire as a relay member.

〔Effect of the invention〕

In the present invention, as described above, since the bipolar coils are connected using the plastically deformable insulated conductive wire, it is not necessary to fix the connecting conductive wire after the connection. Therefore, there are effects such as improving workability and facilitating mechanization.
