Abstract

(57) [Abstract] [Purpose] A holding part for holding the motor is integrally provided in the middle of a pair of battery contact pieces that supplies the energy of the battery to the circuit board, which has high impact resistance and reduces the cost of parts. It is to provide an electric device using a motor. In an electric device driven by a motor 2 using a battery 1 as an energy source, a holding part for holding the motor 2 in the middle of a pair of battery contact pieces 4, 5 for supplying the energy of the battery 1 to a circuit board 7. 4a and 5a are integrally provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electric device using a motor.

[0002]

[Prior art]

 Conventionally, in electric devices driven by a motor using a battery as the energy source, the motor is fixed by sandwiching it between the upper and lower cases, or by screwing the motor to a fixing plate with screws. Was there.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned first conventional technique, the upper and lower cases are likely to open a gap due to an impact or the like, and the fixing of the motor is unstable. Also, since the motor is directly fixed to the upper and lower cases, if an electric device is accidentally dropped, the shock may be directly transmitted and the motor may be damaged. Further, there is a problem that the vibration of the motor is transmitted to the upper and lower cases and the vibration noise of the motor becomes loud.

In the above-mentioned second conventional technique, since the fixed plate is added as a component, there is a problem that the cost of the mold and the cost of the component are increased and the cost of the product becomes high.

Therefore, an object of the present invention is to integrally provide a holding portion for holding a motor in the middle of a pair of battery contact pieces for supplying battery energy to a circuit board, and elastically deform at the time of impact to absorb the impact force. The purpose of the present invention is to provide electric equipment that uses a motor that has high impact resistance and has reduced parts cost.

[0006]

[Means for Solving the Problems]

 An electric device using the motor of the present invention is characterized in that a holding portion for holding the motor is integrally provided in the middle of a pair of battery contact pieces for supplying battery energy to a circuit board.

[0007]

[Action]

 A pair of battery contact pieces 4, 5 accommodates the motor 2 in the respective holding portions 4a, 5a, and one end is soldered to the conductive patterns 7a, 7b of the circuit board 7 provided fixedly, Further, when the motor 2 is attached to the contact piece mounts 3a, 3b of the frame 3 via the setscrews 6, 6, the motor 2 is firmly fixed to the frame 3.

[0008]

【Example】

An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 are diagrams showing a main part of an example of an electric device driven by a motor 2 using a battery 1 as an energy source. An additional mechanism such as a pinion or a cam (not shown) is attached to the motor shaft 2a of the motor 2 according to the purpose of the product. The motor 2 is located on an insulative frame 3, and the frame 3 is formed with contact piece mounts 3a and 3b projecting at different heights with steps. A positive battery contact piece 4 and a negative battery contact piece 5 are fixed to both contact piece mounting bases 3a and 3b with mounting screws 6 and 6.

The battery contact pieces 4 and 5 are provided with half-circular arc-shaped holding portions 4a and 5a, respectively, and the side portion 2b of the motor 2 is attached so as to be enclosed by both holding portions 4a and 5a. Has been done. Therefore, at the time of impact, both the holding portions 4a and 5a bend and absorb the impact force, so that the motor 2 is prevented from being destroyed by the impact. The circuit board 7 is fixedly provided so as to face the frame body 3. The joint portions 4b and 5b electrically joined to the circuit board 7 extend from the holding portions 4a and 5a toward one end portion, and the vicinity of the end portions of the joint portions 4b and 5b are printed on the circuit board 7. The conductive patterns 7a and 7b are respectively soldered. In the vicinity of the other ends of the battery contact pieces 4, 5, there are formed battery pressing parts 4c, 5c extending from the holding parts 4a, 5a and bent at a position approaching the other ends. There are mountain-shaped protrusions 4d and 5d formed at the positions where the battery pressing portions 4c and 5c are in pressure contact with the respective electrodes of the battery 1.

The other end is formed so as to be inclined so that the battery insertion portions 4e, 5e of the battery contact pieces 4, 5 expand outward so that the battery 1 can be easily mounted. The bent portion of the battery contact piece 4c is housed in the escape hole 3c formed in the frame body 3 so that the overall thickness of the battery contact piece 4c does not increase.

In the present embodiment, the holding portions 4a and 5a are formed in a semi-circular shape, but the shape is not limited to this, and any shape may be used as long as it can hold the motor. Needless to say.

[0012]

[Effect of device]

 As described above, according to the present invention, the holding portion for holding the motor is integrally provided in the middle of the pair of battery contact pieces, so that the motor may be unstablely fixed or the motor may be broken due to a shock or the like. There is no. Further, since it is not necessary to provide a fixing plate for fixing the motor as a separate member, the cost of parts can be reduced.
