Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a power supply device for a motor, which can be used for all devices incorporating a motor.

(Prior Art) FIG. 5 shows a conventional power supply device for a motor, in which a lead wire 13 for power supply is directly spot-welded to a protrusion 12 projected from a brush box 11.

(Problems to be solved by the invention) When considering an actuator incorporating a motor now, in the conventional device, when the power feeding device is mounted on the actuator housing or the like, it is necessary that the power feeding lead wire is already mounted on the power feeding device. there were. Therefore, the workability is poor because the lead wire must be routed around the hole of the housing or the rubber for sealing after it is mounted on the housing. Also, in the motor where the condenser is attached to the brush box and the temperature inside the motor may become high,
Since it is necessary to provide this capacitor outside the motor case in order to escape from radiant heat from the motor winding, there is a drawback that the device becomes large in size.

SUMMARY OF THE INVENTION The present invention provides a power supply device that facilitates connection of a power source to a motor by providing a male or female connector integrally with a brush box, and aims to solve the conventional problems.

[Constitution of device]

(Means for Solving the Problem) In a power supply device for a motor having a holder, two brush boxes, an insulating resin housing that is inserted into the holder from the outside, and a capacitor, the brush box is provided in the holder. A male connector or a female connector that is attached to each of the connectors and extends and is integrated with each other is provided. The insulating resin housing has a groove corresponding to a thickness of the holder and the brush box, and a thickness equal to the thickness of the connector. Two grooves and a chamber for accommodating the capacitor, the capacitor electrically connecting to two brush boxes.
And inserting the holder and the brush box into the groove of the insulating resin housing to insert the connector into the two grooves and insulate the connectors from contacting each other. Then, this is a means for solving the problems.

(Function) By inserting the resin housing into the holder, the male connector or the female connector can be inserted into each groove for insulation, and the capacitor is housed in the housing chamber and the terminals of the capacitor are soldered to the brush box. . When the female connector is inserted into the male connector or the male connector is inserted into the female connector in this state, the power supply lead wire can be connected to the motor power supply device.

(Embodiment) The present invention will be described below with reference to embodiments of the drawings.
4 to 4 show an embodiment of the present invention. In the figure, reference numeral 1 denotes a motor power feeder, and brush boxes 3a and 3b to which brushes 2a and 2b are attached are attached to a holder 4. 5a, 5b
Is a male connector, which is covered with an insulating resin housing 6 inserted into the holder 4 from the outside as shown in FIG.
FIG. 2 is a view taken in the direction of arrow A in FIG. 1, FIG. 3 is a view taken in the direction of arrow B in FIG. 1, and FIG. 4 is an example in which brush boxes 3a and 3b are extended to provide an integrated male connector. . The male connectors 5a, 5
A female connector may be used instead of b. Also, the capacitor 7 is inserted from the outside into the upper part of the housing 6,
The terminals 7a, 7b are soldered 8 to the brush boxes 3a, 3b.

The resin housing 6 includes a holder 4 and male connectors 5a and 5b.
Grooves 6a and 6b having a groove width corresponding to the thickness of and are provided so that they can be attached only by inserting them into the holder 4 from the outside, and the capacitor 7 is inserted into the chamber 6c of the housing 6, It is designed to be protected from radiant heat from the motor.

As described above, the male connectors 5a, 5b integrated with the brush boxes 3a, 3b are caulked with the brush boxes 3a, 3b,
It can be easily fixed by sandwiching the resin housing 6. Incidentally, 9 in FIG. 1 is a rotor, 10, 10
Is a lead wire connecting the brushes 2a, 2b and the terminals 7a, 7b.

[Effect of device]

As described above, according to the present invention, since the male connector or the female connector is provided integrally with the brush box, the power supply lead wire may not be assembled when the power supply device is assembled to the housing or the like. Since it is possible to assemble and wire together at the same time, it is easy to assemble.Since there is no need to tie the power supply lead wire to the hole of the housing after assembling it in the housing as in the past, it has excellent workability. There is.

In addition, since the housing for storing the capacitor is provided in the housing made of wood, etc., the radiant heat from the motor winding is not directly received and the capacitor is supported by the resin housing, preventing the capacitor from dropping due to vibration. Since it is possible to dispose a capacitor in the motor, the size of the entire device can be reduced.
