Description

[Detailed description of the invention] [Technical field to which the invention pertains] This invention relates to a battery storage case for electrical equipment or electric toys that has a built-in battery, and in particular a novel battery storage case that is integrated with the battery storage case. This concerns the power switch.

[Prior art and its problems]

BACKGROUND ART Conventionally, in electrical equipment or electric toys containing a built-in battery, the ON/OFF operation of the battery power supply is performed by a switch mechanism connected via a conductive wire led out from a battery storage case. For this reason,
Switch mechanisms require parts such as conductive contacts that touch and separate from each other, and are required to be compact, have excellent operability and durability, but meeting all of these requirements requires a significant increase in manufacturing costs. There is a difficulty in doing so. For this reason, when a relatively low-cost switch mechanism is used, there is a problem in that it is prone to malfunction, and devices, toys, etc. cannot be operated. Also,
When using the conventional switch mechanism mentioned above,
In particular, toys and the like are susceptible to breakage accidents due to shocks and vibrations applied to the outside, and have the disadvantage that they are unable to fully perform their functions as electric toys.

[Purpose of invention]

The purpose of this invention is to omit conductive wires and conductive contacts,
Integrated with the battery storage case to turn on the power.
To provide a battery power switch that can be manufactured at low cost, has a simple configuration that allows reliable OFF operation, is stable in strength, never causes disconnection or contact failure.

[Key points of the idea]

The battery power switch according to the present invention houses a single or multiple batteries, and has a first contact that is in conductive contact with the anode of the battery, and a second contact that is in resilient conductive contact with the cathode of the battery. A through hole is provided in the center of the first contact that makes conductive contact with the anode of one of the batteries stored in the battery housing, and the anode of the battery is inserted into the through hole. The second contact moves forward and backward against the elasticity of the second contact to bring the anode into contact with the first contact.
A pressing member made of an insulating material and having a protrusion that can freely move toward and away from the contact is provided, and a curved stepped portion is provided on the surface that contacts the pressing member in a slidable manner and contacts each other. The present invention is characterized in that a sliding operation member is provided that moves the pressing member forward and backward by engaging the stepped portion.

In this way, in the present invention, one electrode of the battery is forcibly removed from the contact by directly utilizing the function of the contact provided to make conductive contact with the battery housed in the battery compartment. By configuring them to be separated, it is possible to easily realize a battery power switch that has a simple configuration, stable operation, and can be manufactured at low cost.

[Example of idea]

Next, embodiments of the battery power switch according to the present invention will be described in detail below with reference to the accompanying drawings.

1 to 3 show an embodiment of a power switch according to the present invention. That is, the first
In the figure, reference numeral 10 indicates a battery storage case, and this battery storage case 10 is configured as a cassette case that can be attached to and removed from an electrical device or an electric toy, or as a case that is integrated with the body of the electrical device or electric toy. .

However, the battery storage case 10 in this embodiment
is composed of a battery storage section 12 and a switch mechanism section 14 provided adjacent to the battery storage section 12. However, the battery storage section 12 is configured to store a plurality of batteries 16, and is provided with contacts 22 and 24 that make conductive contact with the anode terminal 18 and cathode 20 of each battery 16 stored therein, respectively. . In this case, the contact piece 2 in contact with the anode terminal 18
2 is provided as a fixed flat plate, and the contactor 24 that contacts the cathode 20 is generally made of a spring material that generates elasticity in the axial direction with respect to the battery 16.
Further, each contactor 22, 24 connected to each battery 16 simultaneously stored in the battery storage section 12 is configured so that each battery is connected in series and a constant power output is maintained at a predetermined power terminal (not shown). Configuration is arranged.

Therefore, in the present invention, a through hole 26 is provided in the center of the contact 22 that contacts the anode terminal 18 of any one of the batteries 16 connected in series as described above, This through hole 26
a pressing member 3 made of an insulating material and having a protrusion 28 that is inserted therein and comes into opposing contact with the anode terminal 18;
0 is provided in the switch mechanism section 14. Furthermore, in the switch mechanism section 14, the pressing member 3
a sliding operation member 32 that slides into contact with the battery 16 and moves its protrusion 28 forward and backward in the axial direction of the battery 16;
will be provided. However, this sliding operation member 32
As shown in FIG. 2, when the battery storage case 10 is closed with the cover plate 34, the operation part 38 is exposed through an opening 36 provided in a part of the cover plate 34 and can be operated in a predetermined direction. There is. Further, the contact surfaces between the sliding operation member 32 and the pressing member 30 are provided with curved step portions 32a and 30a (see FIG. 3), so that when they come into contact with each other on the step portions 32a and 30a, The projection 28 of the pressing member 30 is configured to protrude from the end surface of the contactor 22. With this configuration, when the sliding operation member 32 and the pressing member 30 are in contact with each other below the step portions 32a and 30a (when the operation section 38 is positioned at the ON position in FIG. 2), ), the protrusion 28 of the pressing member 30 is set back from the end surface of the contact 22, and the anode terminal 18 of the battery 16 contacts the contact 22 to maintain a conductive state (see FIG. 1). Next, the sliding operation member 32 and the pressing member 30 mutually press the stepped portions 32a and 3
0a (when the operation part is positioned at the OFF position in FIG. 2), the protrusion 28 of the pressing member 30 resists the elasticity of the contact 24 that contacts the cathode 20 of the battery 16. The anode terminal 18 can be pushed away from the contact 22 (see FIG. 3). As a result, the anode terminal 18 of the battery 16 is disconnected from the contact terminal 22, and the power supply is cut off.

[Effect of idea]

As is clear from the embodiments described above, the battery power switch according to the present invention is provided integrally with the battery storage case, and directly utilizes the function of the contacts that contact both poles of the battery to turn on and off the power. Since it is an OFF operation, the conventional conductor wires and conductive contacts for connection with the switch mechanism can be omitted, making it possible to manufacture compactly and at low cost with a small number of parts. Therefore, when the battery power switch according to the present invention is applied to electric toys, etc., problems such as failure of the switch mechanism and disconnection accidents due to shock and vibration are solved, and it is possible to easily manufacture robust electric toys at low cost. be able to.

In addition, in the above-mentioned embodiment, a case was shown in which the sliding operation member and the pressing member constituting the switch mechanism part were engaged with each other so that the mutually contacting surfaces were as shown in the figure, but the present invention is not limited to this embodiment. Needless to say, various configurations can be employed as long as the mechanism allows the protrusion that contacts the anode terminal of the battery to move forward and backward without any problems.

Although the preferred embodiments of the present invention have been described above, it goes without saying that various improvements and changes can be made without departing from the spirit of the present invention.
