Abstract

(57) [Abstract] [Purpose] To provide a terminal of a battery power supply device capable of removing oxide even if oxide is attached to the surface of a device terminal. A terminal main body 12 is provided in a mobile device main body 1 in which a battery accommodating portion having a pair of battery terminals is mounted, and is bent into a mountain shape, and a conductor is provided on one inclined portion of the terminal main body 12. And a brush portion 13 that stands upright.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a battery power supply device, and more particularly, to a structure of a terminal provided in a main body of a mobile device such as an 8 mm video camera or a mobile phone which is driven by a battery.

[0002]

[Prior art]

 FIG. 3 is a terminal explanatory view for explaining the terminals of the conventional battery power supply device, FIG. 4 is a perspective view of the device terminals provided in the portable device body, and FIG. 5 is a view for explaining the operation of the conventional device terminals. FIG.

In FIG. 3, reference numeral 1 is a main body of a mobile device such as a mobile phone which uses a battery 4 as a power source, and 2 is a pair of device terminals provided side by side with the main body 1 of the mobile device, and is bent into a mountain shape as shown in FIG. Although not shown, the end portion of one of the inclined portions is fixed to the portable device body 1 side. Reference numeral 3 denotes a battery pack that accommodates a plurality of batteries (for example, AA dry batteries) 4 adjacent to each other, and a battery terminal 5 is provided on the bottom of the battery pack so as to face the device terminal 2.

Next, the operation of the device terminals will be described with reference to FIG. When the device terminal 2 is not pressed, the folded portion 2a of the device terminal 2 is on the center line of the battery terminal 5 (see FIG. 5A), but when the device terminal 2 is pressed by the battery terminal 5. The end of the other inclined portion of the device terminal 2 rotates in the direction of arrow a with the fixed end 2b as a fulcrum, and the folded portion 2a of the device terminal 2 is pressed by the battery terminal 5. , Slide the contact surface of the terminal 5 in the direction of arrow B to stop (see Fig. 5 (b)). When the folded portion 2a of the device terminal 2 slides, the contact surface of the battery terminal 5 is rubbed by the folded portion 2a, so that the contact surface is cleaned.

[0005]

However, in the configuration of the conventional device terminal 2, when the folded-back portion 2a of the device terminal 2 slides on the contact surface of the battery terminal 5, microspark may occur. When this phenomenon overlaps, as shown in FIG. 6, oxide may adhere to the folded-back portion 2a of the device terminal 2, resulting in poor contact.

The present invention has been made in order to solve such a problem, and an object thereof is to provide a terminal of a battery power supply device capable of removing an oxide even if an oxide adheres to the surface of a device terminal.

[0007]

[Means for Solving the Problems]

 The terminals of the battery power supply according to the present invention are formed by bending in a mountain shape, and one end of one of the inclined portions is fixed to the body of the portable device, and is attached to the battery storage portion that houses the battery. The terminal main body is in contact with the battery terminal, and the brush portion is in contact with the pair of battery terminals.

[0008]

[Action]

 According to the present invention, since the battery terminal presses the terminal body of the portable device body when the battery accommodating part is attached to the portable device body, the other inclined portion of the terminal body is lowered with the fixed end portion as a fulcrum. While turning, the folded portion of the terminal body that comes into contact with the battery terminal slides, and at this time, the brush portion that stands on one inclined portion of the terminal body also comes into contact with the battery terminal and slides.

【Example】

 1 is a perspective view of a device terminal for explaining an embodiment of the present invention, and FIG. 2 is an operation explanatory view for explaining the operation of the device terminal. Incidentally, the same or corresponding parts as those of the conventional example described in FIG.

In FIG. 1, reference numeral 11 denotes a device terminal including a terminal body 12 and a brush portion 13 of the present invention, which faces a pair of battery terminals 5 mounted on a battery pack 3 containing a battery 4. The terminal body 12 is formed by bending in a mountain shape, and one end of the inclined portion is fixed to the portable device body 1 side. The brush portion 13 is provided on the surface of one of the inclined portions of the terminal body 12, and is formed by bundling, for example, gold-plated thread-like copper wires, and is fixed to the inclined portion by welding or driving. ing. Alternatively, the brush portion 13 may be configured by arranging copper plates at predetermined intervals.

The operation of the device terminal configured as described above will be described with reference to FIG. As in the conventional case, when the battery terminal 5 is not pressing the terminal body 12, the folded-back portion 12a of the terminal body 12 is on the center line of the battery terminal 5 (see FIG. 2A). When the battery terminal 5 is pressed by the battery terminal 5, the end of the other inclined portion of the terminal 12 rotates in the direction of the arrow a with the fixed end 12b as a fulcrum, and the folded-back portion 12a of the terminal body 12 becomes the battery. As the terminal 5 is pressed, it slides in the direction of arrow B and stops (see FIG. 2B). At this time, the brush portion 13 also slides while contacting the contact surface of the battery terminal 5, and rubs the contact surface together with the folded portion 12a.

[0012]

[Effect of device]

 As described above, according to the present invention, the brush portion of the conductor is attached to the terminal body of the portable device body to make contact with the battery terminal at multiple points, so that the microspark is reduced, and moreover, the contact of the battery terminal is reduced. The effect is that the cleaning ability of the surface is improved compared to the conventional one.
