Description

Description: TECHNICAL FIELD The present invention relates to a lead wire to the outside of a motor using a mounting plate attached to a stator of the motor, and a method of connecting magnetic pole windings.

[Conventional technology]

When creating a stator for a motor, an iron core material such as a silicon steel plate is laminated and fixed on the upper and lower sides using a molded product made of an insulator such as nylon. A magnetic pole is formed by providing a winding.

FIG. 2 is a plan view of the stator of the electric motor as viewed from above.

An iron core 101 and an insulator 102 are assembled, and a magnetic pole winding 103 is formed on a protruding portion of the iron core.

Next, after winding an external lead wire 105 around the terminal 104 and soldering, the terminal 10 is inserted into a terminal mounting hole 106 provided in the insulator 102.
After inserting and fixing 4, the terminal of the magnetic pole winding 103 is wound around the terminal 104 and soldering is performed by dipping.

The above assembly structure will be described in detail with reference to the perspective view of FIG.

In assembling, the leading end of the lead wire 201 from which the insulator has been removed is first attached to the terminal 202, and the terminal 202 and the lead wire 201 are soldered.

Next, the terminal 20 is inserted into the terminal mounting hole 204 provided in the insulator 203.
2 is inserted and fixed one by one, the tip of the magnetic pole winding 205 is wrapped around the terminal 202 as shown in the figure, and when all the terminals have been processed, a method of dipping with a solder bath is used. Was.

[Problem to be solved]

In the case of the above-described method, it takes time and effort to shape and hold the lead wire so that the lead wire is not damaged during solder dip. In addition, the lead wire is tied to the terminal and soldered. A lot of man-hours were required to insert and fix it.

In order to solve the above-mentioned problems, the present invention has a structure in which a conventional structure is modified to provide a single insulating plate on one end surface of a stator of an electric motor and to hold the insulating plate by an insulator constituting the stator. Holding the lead wire using the insulating plate,
By directly winding the terminal of the magnetic pole winding around the core wire of the lead wire protruding from the hole provided in the insulating plate and performing solder dip, a method of making the terminal unnecessary and greatly reducing the number of work steps is described. The purpose is to provide.

[Means for solving the problem]

In order to achieve the above object, according to the present invention, the lead wire is fixed via a lead wire holding projection provided on one surface of the lead wire mounting plate, and then the other end of the lead wire mounting plate is removed from the lead wire holding hole. The core wire of the lead wire drawn out to the surface of the lead wire is taken out, and the end of the magnetic pole winding drawn out through the concave portion for drawing out the magnetic pole winding provided on the lead wire mounting plate is wound around the core wire, and the lead wire is wound. We have developed a method of connecting the lead wire to the outside of the motor and the magnetic pole winding, which is characterized in that the mounting plate is connected to the insulator constituting the stator and then soldered by dipping.

[Action]

The lead wire mounting plate and the insulator by this connection method are assembled as follows.

The stator sheet core and the insulator, which constitute the stator of the motor, are assembled and the required winding is performed on each pole of the stator by an automatic winding machine.

The lead wire to the outside is cut to the required length, and the lead wire holding protrusion formed on one side of the lead wire mounting plate secures the lead wire while covering the lead wire to the required length. The core wire of the removed lead wire is pulled out from the lead wire holding hole of the lead wire mounting plate to the other surface of the lead wire mounting plate.

A magnetic pole winding is wound around the lead core wire, and the lead wire mounting plate is pressed into an insulator constituting the stator to perform solder dip.

According to the above method, the lead wire is fixed by the lead wire attaching plate, and the lead wire does not directly contact the solder of the solder bath, so that the lead wire is not damaged. Further, it is not necessary to use a large number of terminals as in the related art, and it is also unnecessary to solder many terminals and insert the terminals into the mounting holes.

The core wire of the leading end 7 from which the insulating coating of the lead wire 6 has been removed is fixed to the lead wire 6 via the protruding portion of the lead wire holder 5 provided on one surface of the lead wire mounting plate 1 and then held. The lead wire is pulled out from the hole 4 to the other surface of the lead wire mounting plate 1, and the magnetic pole winding 103 drawn out from the concave portion 3 for drawing out the magnetic pole winding is wrapped around the core wire of the leading end portion 7 of the lead wire 6. The mounting plate 1 is made of an insulator 102 constituting a stator.

By attaching the leading end 7 of the lead wire drawn out of the magnetic pole winding 103 into the molten solder 301 in the solder bath 302,
The core wire of the lead wire 6 and the magnetic pole winding are soldered simultaneously.

The lead wires 6 can be fixed to the left and right by three protruding portions of six wire restraints 5 provided on one surface of the lead wire mounting plate 1, and the lead wires 6 come into contact with the solder surface by the lead wire mounting plate 1. Can be prevented, and there is no risk of damage.

Further, since the lead wires can be collectively pulled out by the lead wire collective lead-out portion 8 of the lead wire mounting plate 1, post-work is facilitated.
