Abstract

PURPOSE:To facilitate assembling and wiring by fixing a case B having printed board to one side of a body case A containing a motor and connecting the motor with the printed board through a through-hole of the case B. CONSTITUTION:The case for a device body 1 comprises a body case 2(A) and an upper case 7(B). The case 2 contains a motor 3 and rotates/stops rotation of a rotor 4 through a clutch 6 thus rotating the output shaft 8 through plural stages of reduction mechanisms 5 and final stage gears 5a, 5b while resisting against the force of a spring P. A terminal 22 projecting from a motor coil 14 through a through-hole 23 of the case 7 is fitted to the fitting section of a printed board 21 fixed to the case 7. Cam board 12 of the output shaft 8 opens/closes a contact 13 and controls opening/closing of a damper (not shown) fixed to the output shaft 8 together with a solenoid 10 interlocked with the clutch 6. Since only internal wiring is required except at the source line lead-in section, number of parts is reduced and assembling time is shortened.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a drive for an opening/closing mechanism, which is connected to an opening/closing mechanism such as a damper in an air conditioner, and is equipped with a motor used for opening/closing the opening/closing mechanism. It is related to the device.

[Prior Art] The present applicant has developed a drive device for an opening/closing mechanism as shown in FIG. In this figure, numeral 1 is the main body of the device. This device body 1 includes a bottomed cylindrical body case (case A) 2, a motor 3 housed inside this body case 2, and a plurality of gears that sequentially decelerate the rotation of a rotor 4 of this motor 3. A reduction mechanism 5 consisting of a group and a rotor 4
and a clutch mechanism 6 that connects and disconnects the transmission of rotation from the to the deceleration mechanism 5.

A box-shaped upper case (case B) 7 is attached to the opening of the main body case 2 to close the opening. A blade shaft 8 fitted into the shaft 5b of the last stage gear 5a of the speed reduction mechanism 5 is inserted into the upper case 7. This output shaft 8 protrudes to the outside, and a lever 9 is fitted to the protruding end. This lever 9 is connected to a drive shaft of a damper (opening/closing mechanism) such as a ventilation fan or an air conditioner (not shown).

Further, inside the upper case 7, there is a solenoid 10 that connects and disconnects the clutch mechanism 6, and a solenoid 10 that turns on and off the motor 3.
A switch device 11 for OFF operation is provided.

The solenoid 10 is disposed above the clutch mechanism 6, and operates to connect the clutch mechanism 6, which is normally disconnected, by applying direct current to the solenoid coil.

Further, the switch device 11 is composed of a cam plate 12 fitted to the output shaft 8, and two contacts 13, 13 configured to be attached or separated by rotation of the cam plate 12. be.

Here, a lever 9 provided at the protruding end of the output shaft 8 is normally stopped by a return spring P at a position where the damper is fully closed. Further, in this state, the switch device 11 is set to be turned on.

Further, in this device, the motor coil 14 of the motor 3
The respective terminals 1g and +5 to which both ends are connected are connected in the radial direction of the winding bobbin 16 with respect to the thick part 16b formed on the upper flange 16a of the winding bobbin 16 around which the motor coil 14 is wound. It is fitted so that it protrudes outward.

These terminals 1515 pass through a cap 2a fitted to the main body case 2, and their protruding ends are exposed to the outside of the main body case 2.

One of these terminals 15.15 is connected to one contact 13 of the switch device 11 by a lead wire 17. In addition, the terminal 15 and contact 13 on the other side
is connected to a damper opening/closing switch (not shown). Further, the solenoid fill of the solenoid 10 is connected to the electric circuit of the motor 3.

The function of this device is that when the switch for opening and closing the damper is turned on, the motor 3 is energized via the switch device 11 which is initially in the ON state, and the solenoid 10 operates to connect the clutch mechanism 6. . Then, the rotation of the rotor 4 of the motor 3 is transmitted to the output shaft 8 via the clutch mechanism 6 and the speed reduction mechanism 5, and the lever 9 rotates against the return spring P. Then, the drive shaft of the damper rotates and the damper opens (. Then, when the output shaft 8 rotates by a predetermined angle, the contact 13 is opened by the action of the cam plate 12 of the switch device 11.
．． 13 is separated and the switch device 11 is turned off,
The opening operation of the damper stops.

Further, when the damper opening/closing switch is turned OFF, the operation of the solenoid 10 is canceled and the clutch mechanism 6 is turned off. As a result, the output shaft 8 becomes rotatable, the lever 9 is returned to its original position by the action of the return spring P, and the damper is closed. At this point, the switch device 11 is also turned ON again.
will be returned to the state of

[Problems to be Solved by the Invention] By the way, in a device having such a structure, the terminal 15
The contacts 13 of the switch device 11 and the switch device 11 cannot be connected to each other without using the lead wire 17, and this connection work is performed by soldering or the like, which is laborious and time-consuming. Furthermore, since terminals 15.15 and lead wires 17 are exposed to the outside of the device, lead wires 17.
There was a risk that a hand or other device could get caught in the wire, weakening the connection or breaking the wire.
