Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a motor winding lead-out terminal for connecting a motor winding and a lead wire.

BACKGROUND ART Conventionally, the windings of a motor and lead wires have been connected by soldering, as shown in FIG. This soldering was performed after the insulating film at the end of the winding was manually peeled off and then wound around the lead wire.

Problems to be Solved by the Invention With such a conventional connection structure, automation is difficult. In particular, it has been difficult to automate peeling off the insulation film of the winding wire and winding it around the lead wire. On the other hand, in the field of electrical machinery, a thermocompression bonding method (fusing method) has been developed in which a copper wire with an insulating film is directly electrically connected to a metal plate or the like.

An object of the present invention is to provide a motor winding lead-out terminal suitable for automating the connection of motor windings and lead wires using the fusing method described above.

Means for Solving the Problems In order to achieve the above object, the motor winding lead-out terminal of the present invention has a plurality of hook parts for fusing and connecting the wire ends of a plurality of motor windings to the terminal body. and an insulation support portion for fixing the plurality of windings and lead wires to the terminal body, and the angle between the plurality of hook portions and the terminal body is in the range of 45° to 90°. They are each configured differently.

Effect This configuration allows the winding ends of multiple windings to be fusing connected to the hook part in different directions, and since the windings do not overlap when connected,
Automation using robots becomes possible. Furthermore, since a plurality of windings and lead wires can be fixed simultaneously at the insulation support section, disconnection of the windings and poor connection at the hook section can be eliminated.

Embodiment FIG. 1 shows an embodiment of the motor winding lead-out terminal of the present invention. In Figure 1, 10
1 is the terminal body, and 1, 2, and 3 are hook portions to which the windings are fixed and connected by fusing. These hook parts have three windings (main winding 5) as shown in the common lead wire part in the motor wiring diagram in Fig.
Even if the main winding 5 has two terminals and the auxiliary winding 6 has one terminal, the same terminal can be used for two terminals for the main winding 5 and one terminal for the auxiliary winding 6. .

These hook parts 1, 2, and 3 have different angles with the terminal body 10, A=45°, B=60°,
C=90°. As a result, even when there are three windings, the ends of the windings can be inserted and fixed into the terminals smoothly without overlapping the windings.

Note that if the angle A of the hook part 1 is less than 45°,
As shown in Figure 2, in a terminal that has been crimped by bending the hook part 1, the D dimension of the hook part 1 becomes larger, and the overall size of the terminal becomes larger. When shaping the line, workability deteriorates and there is a greater possibility of problems such as layer defects occurring.

The angles A, B, and C of this hook part are A<B<C
If it were, it would be easier to arrange the windings as shown in Figure 2, and it would be easier to automate.

The insulation support part 4 shown in FIG. 1 has different sizes on the left and right sides, and the direction of the hook part is made larger to improve the material removal of the terminal.

FIG. 2 shows the state after the windings and lead wires are connected to the terminals shown in FIG. 1. In the order of connecting the windings and lead wires, first, the lead wire 7 is connected to the terminal body 10 by welding or fusing. Next, the main winding 5 and the auxiliary winding 6 are simultaneously crimped onto the hook parts 1, 2, and 3 by fusing, thereby thermally melting the insulation coating of the windings.
This allows conduction and maintains mechanical strength. Then, fix the lead wire and the winding together using the insulation support. By fixing with this insulation support, movement of the winding can be suppressed and disconnection and poor connection caused by movement of the winding at the connection part can be eliminated.

Effects of the invention As described above, according to the invention, the connection between the winding and the lead wire can be automated, and a low-cost electric motor with stable quality can be provided.
