Description

  The present invention relates to a battery accommodating device used for a remote control transmitter or the like that is used for remote operation of various audiovisual equipment and is driven by a battery.

  In recent years, electronic devices such as remote control transmitters used for remote control of various audiovisual equipment and portable devices such as information terminals have been used for power saving, and cylindrical batteries are used as power sources for these electronic devices. Many of them are equipped with a battery storage device that can freely store and remove the battery (insertion and removal).

  Regarding such a conventional battery housing device, a battery housing mode will be described in particular.

  First, the battery used in the battery housing device is defined by Japanese Industrial Standards such as alkaline dry batteries and manganese dry batteries, and is generally classified as AA type by its external dimensions.

  These batteries have a projecting positive electrode on one side of a cylindrical body and a flat negative electrode on the other in order to extract the internal capacity (hereinafter referred to as battery voltage) to the outside. Are displayed, and +,-, etc. are displayed to divide the electrodes into their outer shapes.

  And the said battery accommodating apparatus is provided with the battery accommodating part which can accommodate the said battery so that attachment or detachment is possible, In this battery accommodating part, two electrodes, the positive electrode of the said battery for extracting the said battery voltage outside, and the negative electrode A pair of electrode terminals in contact with each other is provided.

  The pair of electrode terminals are opposed to the two electrodes of the battery, and at least one of them is a plate-shaped metal plate, which is processed into a spring shape with a spring-shaped or thin rod-shaped metal, and has elasticity. Is arranged at a predetermined position of the battery accommodating portion so as to be in electrical contact with each electrode of the battery.

  Note that the battery insertion direction is clearly shown on the bottom surface of the battery housing portion by displaying a so-called battery mark that imitates the outer shape of the battery.

  Further, the battery housing device includes a lid so as to cover the upper opening of the battery housing portion so that the battery inserted into the battery housing portion does not easily fly out due to dropping or the like. Has a latching portion such as a claw so as to be engaged with the battery housing portion to constitute a battery housing device.

  In the above configuration, the replacement of the battery, for example, is performed by first opening the latching portion of the lid to expose the upper opening of the battery housing portion, and removing (removing) the old battery from the battery housing portion. The battery is inserted and the lid is re-engaged with the battery housing portion, and the user can attach or remove the battery from either the positive electrode or the negative electrode.

  In addition, battery attachment / detachment is not limited to the replacement of old and new batteries. When a battery inserted into the battery compartment is ejected due to a fall of the battery compartment, etc., the battery in use is frequently removed. However, especially when the battery is detached, the battery is forcibly removed by the user, the battery electrode is damaged by the electrode terminal, the contact resistance increases during this time, heat is generated, and the electrode terminal is deformed. Therefore, it has been proposed to provide a hook over the elastic electrode terminal to make it difficult for the user to forcibly remove the battery and prevent deformation of the elastic electrode terminal.

  However, in the above conventional battery housing device, the battery can be attached / detached from either the positive electrode or the negative electrode, and even if the battery direction is wrong, it will not be noticed until it is operated, and the battery must be reinserted in the correct direction. There was a problem that had to be done.

  The present invention solves such a conventional problem, and an object of the present invention is to provide a battery housing device that is convenient for use without changing the battery direction when a battery is attached or detached.

  In order to achieve the above object, the present invention has the following configuration.

  According to the first aspect of the present invention, hook-like protrusions having different shapes are integrally formed at both ends of the upper surface opening of the battery housing part, and the attachment / detachment direction of the battery is regulated by the hook-like protrusions. Therefore, it has an effect that it can be attached and detached only in a predetermined direction.

  According to a second aspect of the present invention, in the first aspect of the present invention, the hook-shaped protrusion is formed from a concave hook-shaped protrusion on the positive electrode side of the battery and a convex or concave hook-shaped protrusion on the negative electrode side. It is configured, and has an effect that the battery can be attached / detached only in a predetermined direction when the battery is attached / detached.

  According to a third aspect of the present invention, in the first aspect of the present invention, the upper surface opening of the hook-shaped protrusion is formed shorter than the entire length of the battery, and the inserted battery is not easily ejected. Has an effect.

  According to a fourth aspect of the present invention, in the second aspect of the present invention, the hook-shaped protrusion on the positive electrode side is formed between the positive electrode of the battery and the outer shape of the battery body. Only the direction can be attached and detached, and the effect is that it cannot be attached and detached in the opposite direction.

  As described above, according to the present invention, when a battery is attached to or detached from the battery housing portion, an advantageous effect that the attaching / detaching direction of the battery is not mistaken can be obtained.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

(Embodiment)
The invention according to claims 1 to 4 of the present invention will be described using the embodiments.

  FIG. 1 is a cross-sectional view of a main part of a battery housing device according to an embodiment of the present invention. In the figure, 1 is a battery having a positive electrode 1B and a negative electrode 1C at both ends of a cylindrical main body 1A, and 2 is a battery 1. The positive electrode 1B, the positive electrode terminal 2A facing the negative electrode 1C, and the negative electrode terminal 2B are a pair of electrode terminals.

  Reference numeral 3 denotes a battery housing portion that can detachably store the battery 1. The battery housing portion 3 is in electrical contact with the positive electrode 1 </ b> B and the negative electrode 1 </ b> C of the battery 1 in order to draw the battery voltage of the battery 1 to the outside. Further, a negative electrode terminal 2B formed of a thin rod-like metal in a spring shape, and a pair of electrode terminals 2 that are in contact with the positive electrode terminal 2A by being energized by the negative electrode terminal 2B. Are arranged at predetermined positions.

  Reference numeral 4 denotes a pair of hook-shaped protrusions that are integrally formed at both ends of the upper surface opening 3A of the battery housing portion 3 so as to be shorter than the entire length of the battery 1, and the hook-shaped protrusion 4 is a hook-shaped protrusion 4A on the positive electrode side of the battery 1. And a hook-like protrusion 4B on the negative electrode side of the battery 1.

  Here, in the plan view of the battery accommodating device of FIG. 2, the pair of hook-shaped protrusions are concave so that the positive electrode 1B of the battery 1 can pass through the hook-shaped protrusion 4A on the positive electrode side and the negative electrode 1C of the battery 1 cannot pass. The negative projection 4B on the negative electrode side is protruded greatly on the upper surface of the main body 1A of the battery 1, and is formed in a concave shape so as to have an opening 4C on the upper surface.

  The negative projection 4B on the negative electrode side in FIG. 1 is formed in a convex shape so as to protrude largely from the upper surface of the main body 1A of the battery 1.

  3 is a cross-sectional view taken along the line AA of the positive-side hook-like protrusion 4A in FIG. 2. The positive-side hook-like protrusion 4A is formed between the positive electrode 1B of the battery 1 and the outer shape of the battery body 1A. Yes.

  4 is a cross-sectional view taken along the line B-B of the concave hook-shaped protrusion 4B on the negative electrode side in FIG. 2. The difference from the convex hook-shaped protrusion 4B shown in FIG. What is necessary is just to make the opening width w2 smaller than the outer diameter Φ1 of the battery 1, and by doing so, the upward movement distance of the battery 1 increases the convex hook-like protrusion 4B (on the upper surface of the battery 1). The height can be lowered by h2 as compared with the convex hook-shaped protrusion 4B.

  Here, it is preferable to display on the top surfaces of the pair of hook-shaped projections 4 such as + and − for distinguishing the electrodes of the battery 1 (FIG. 2).

  With the above configuration, the operation of the battery insertion / removal mode insertion / removal method when the battery is replaced will be described.

  5 and 6 are schematic views showing the battery insertion direction. FIG. 5 is a normal insertion direction (hereinafter referred to as a forward direction), and FIG. Hereinafter, it is described as a wrong direction).

  First, the insertion operation in the positive direction in FIG. 5 is performed by inserting the battery 1 into the battery housing part 3 obliquely from the upper left side to the negative electrode 1C (right side in the drawing) first while inserting the negative electrode 1C (right side in the figure). The negative electrode 1C reaches the electrode terminal 2B on the negative electrode side while being regulated at the tip of the electrode.

  Further, when the battery 1 is continuously inserted against the urging force of the negative electrode terminal 2B and reaches the elastic limit position of the negative electrode terminal 2B, the insertion movement of the battery 1 in the right direction naturally occurs. When the positive electrode 1B of the battery 1 is secured and a gap that allows the positive electrode 1B to pass through the concave portion of the hook-like protrusion 4A on the positive electrode side is secured, the battery 1 is pressed in the direction of ↓ that is substantially perpendicular to the left-right upper direction. Housed in part 3.

  The accommodated battery 1 is moved by the urging force of the negative electrode terminal 2B, and the positive electrode 1B of the battery 1 and the positive electrode terminal 2A are in electrical contact.

  Next, the insertion operation in the wrong direction of FIG. 6 is to insert the positive electrode 1B (right side in FIG. 6) first from the left obliquely upward direction to the battery housing portion 3, and the positive electrode 1B. The first electrode terminal 2B on the negative electrode side is reached while being regulated by the tip of the negative projection 4B on the negative electrode side.

  Furthermore, even if the battery 1 is continuously inserted against the urging force of the electrode terminal 2B on the negative electrode side, the battery 1 can be accommodated in the battery 1 because the negative electrode 1C of the battery 1 cannot pass through the hook-shaped protrusion 4A on the positive electrode side. It cannot be accommodated in part 3.

  Further, as an operation of inserting the battery 1 in the wrong direction, it is conceivable that the battery 1 is inserted into the battery housing portion 3 from the upper right and the negative electrode 1C (or the positive electrode 1B) first, but the positive electrode 1B to be inserted later. (Or the negative electrode 1C) is formed in a convex shape or a concave shape so that the negative hook-side protrusion 4B protrudes largely from the upper surface of the main body 1A of the battery 1, and therefore the battery 1 is not accommodated in the battery accommodating portion 3. Can not.

  In the above description, only the method of inserting / removing the battery has been described. However, since it can be easily understood that the attaching / detaching method can be performed only from the reverse procedure of the inserting method, that is, from the positive electrode 1B side of the battery, the description is simplified. Turn into.

  As described above, according to the present embodiment, since the hook-like protrusions having different shapes are integrally formed at both ends of the upper surface opening of the battery housing part, the attachment / detachment direction of the battery can be regulated by the hook-like protrusions. When the battery is attached / detached, a battery housing device that can be attached / detached in the positive direction of the battery 1 and cannot be attached / detached in the wrong direction can be obtained.

  Further, by making the hook-shaped protrusions concave on the positive electrode side and convex or concave on the negative electrode side, it can be similar to the outer shape of the battery to be accommodated (protruding positive electrode) and can be easily recognized by the user.

  Furthermore, by making the upper surface opening formed by the hook-shaped protrusion shorter than the total length of the battery, it is easy for the user to visually recognize that the battery is attached and detached, and the inserted battery can be easily discharged. It is something that can be avoided.

  Further, by forming the hook-like protrusion on the positive electrode side between the positive electrode of the battery and the outer shape of the battery main body, only the positive electrode of the battery can contact the electrode terminal on the positive electrode side.

  In the prior art, a lid that covers the battery housing is essential, but the lid may be damaged when the battery housing is dropped and cannot be used, or may be lost when replacing the battery. Without the lid, the battery housed in the battery housing part is easily inconvenient to be easily detached from the battery housing device. It is convenient to use because the battery cannot be easily removed.

  In addition, the battery housing device of the present application can be implemented even if it is provided integrally with the main body of the electronic device.

  The battery accommodating device according to the present invention has an effect that when the battery is attached to and detached from the battery accommodating portion, the direction of attaching and detaching the battery is not mistaken, and is used for remote operation of various audiovisual equipment and driven by the battery. This is useful for electronic equipment using a battery housing device such as a remote control transmitter.
