Description

【0001】
【発明の属する技術分野】
本発明は、電子機器等の電池蓋ロック装置に関する。
【0002】
【従来の技術】
カメラにおいて、電源として用いられる縦長の電池は、通常、カメラ本体外装部の底面から挿入され、カメラの底面に垂直な方向を軸として収納配置されている。そして、電池挿入用の開口を塞ぐための電池蓋には、蓋を閉位置に留めておくために、専用のロック部材が備えられている。電池がカメラ本体内に装着されている場合、ばね性を有する電池の接続用接片の弾性力によって、電池蓋には開放方向に付勢力が働くが、ロック部材により電池蓋は所定の閉位置に保持されるようになっている。
【0003】
電池蓋を閉位置に保持するためのロック機構は専用の部材で構成されているので、専用部品としてのコストがかかる。また、ロック機構の配置スペースが必要であり、この配置スペースも電池収納部付近の寸法を大きくする要因の一つとなっている。
【0004】
電池の非装着時においても電池蓋を容易に開放できるようにし、操作性を向上させたカメラの電池蓋がある。この技術は電池収納部の開口部を覆う電池蓋の表面には電池蓋ロック部材を設け、通常の電池接続用接片を設け、電池蓋の閉位置において電池蓋に弾性変形を生じさせ、電池蓋に開放方向への付勢力を与える技術である(例えば、特許文献1参照。)。
【0005】
この技術は電池を収納していない場合に蓋が開きにくいのを改善するものであって、電池収納時の電池の電極と電池接片との押圧を改善する技術ではない。
【0006】
【特許文献1】
特開平11−44908号公報(第2−8頁、図4)
【0007】
【発明が解決しようとする課題】
電池がカメラ本体内に収納されている場合、通常、蓋部材に電池接片が取付けられている。電池の電極と電池接片との接触が不十分であると、この部分に電気抵抗が生じ、電池を有効に使い切ることができない。近年は、カメラの性能が改善され、低電圧で作動するようになっているので、特にその影響が大きい。
【0008】
そこで、電池の接触圧を上げることにより、電池との接触抵抗を低減し、撮影枚数を増加させることができる。しかし従来、電極と接片との接触は蓋に取付けられている接片によりなされるので、接触圧を高めると、電池蓋の開閉操作力が大きくなりすぎ、蓋を閉じることが困難になるという欠点があった。
【0009】
本発明は上記問題点を解決し、蓋の開閉動作になんら困難性を生ずることなく電池の電極と接片との接触圧を高めることができる技術を提供することを目的とするものである。
【0010】
【課題を解決するための手段】
本発明は、電池を使用する機器において、電池の蓋ロック機構に電池を押圧する押圧手段を付与したことを特徴とする電池蓋ロック装置である。
【0011】
さらに具体的には前記押圧手段は、蓋ロック機構の背面に設けられた凸起とし、蓋ロック機構をロックしたとき前記凸起は電池の接片を電極に押圧する位置に前進し、ロック解除に伴って電池の接片を電極に押圧する位置から退避する凸起とする。
【0012】
この押圧手段は電池蓋ロック機構と電池接片を連動させ、ロックを行うと同時に電池接片に曲げを与え、電池との接触圧を高める。これにより、電池蓋の開閉操作力を高めることなく、電池接触圧のみを高くすることができる。
【0013】
前記押圧手段の別の態様としては、蓋ロック機構の背面に設けられた弾性部材とし、該弾性部材は蓋ロック機構をロックしたとき、電池の側部を押圧して電池を電池室壁に密着させ、ロック解除に伴って、電池の側部の押圧を解除し、電池から離れる弾性部材とする。
【0014】
従来の蓋ロック装置は、電池蓋をロックするのみであったが、本発明により他の作用を付加され多機能の部材となった。
【0015】
【発明の実施の形態】
本発明は、電池蓋をロックするとその動作に伴って同時に電池接片の接触圧を大きくするか又は電池を壁に押しつけて電池の遊動を阻止して接点を安定させ、接触部の電気抵抗を低減させるものである。
【0016】
以下図面を参照して本発明の実施の形態を説明する。
【0017】
図2は本発明の実施例の電池蓋ロック装置10を示す側面図である。
【0018】
電池50が収納される収納室51の蓋52は本体キャビネット53に蝶番構造で取付けられている。この蓋52の背面には電池蓋ロック装置10が取付けられている。蓋52を閉止した後、ロック装置10の爪11を矢印12方向にシフトするとロック装置10の先端13はキャビネットに設けたロック孔54内に進入し蓋52は閉止ロック状態となり開かなくなる。ロック装置10を矢印12と逆方向にシフトすると、ロック装置10の先端とロック孔54との係合が解除され蓋52を開くことができる。
【0019】
本発明ではこのロック装置10の背面に突起14を設け、ロック装置10を矢印12方向にシフトしてロック状態にしたとき、突起14が電池50の接片60を押圧するようにした。
【0020】
図1はこのロック装置10と接片60との関係を示す説明図である。接片60は蓋52の背面に取付けられ、接触部61,62が電池に接して導通する。図1(a)はロック装置10を図2の矢印12方向にシフトする前の状態を示すもので接片60の高さ(蓋52の裏面と接点との距離)aとなっている。ロック装置10は接片60を押す状態になっていない。
【0021】
図1(b)はロック装置10を図2に示す矢印12方向にシフトした状態を示すもので、ロック装置10の突起14が接片60を押圧している状態を示す。突起14の高さをbとし、図1(a)の状態でロック装置10が接片に接していたとすると接片は突出高さbだけ押圧され、図1(b)に示すように、接片の電池との当接部はほぼ(a+b)に近似する寸法となる。
【0022】
図3〜5は別の実施例を示すもので、図3は蓋52を取去ってロック装置10の作動を説明するようにした正面図、図4はそのA−A矢視断面図である。
【0023】
符号10〜13、50〜54は図1、図2と同様である。異なる点は、ロック装置10の背面に軸15を突出し、この軸に弾性リング16を外嵌し、ロック装置10を矢印12方向にシフトしたとき、この弾性リング16が2ケの電池50及び50aの側面を押し付けるようにした点である。図5はこの動作を説明する説明図で、2ケの電池50、50aと弾性リング16との関係を示している。ロック装置10が図4の矢印12方向にシフトする前には弾性リングは16aの位置にあり、電池50、50aと接していない。ロック装置10を矢印12(図4)方向にシフトしたとき、弾性リング16aは矢印17方向に移動し2ケの電池の側面に接する位置(16)に押圧され、電池50、50aの間のくさび状の隙間に食い込む。
【0024】
従って、電池50、50aは強く側面に押しつけられて電池室内の壁面に押圧固定される。
【0025】
この固定により、電池は撮影姿勢の変更や振動等に対して安定しており、接点が移動等を生じない。従って接点の電気抵抗が安定的に保たれ、低電圧でも作動し電池の寿命延長に寄与する。
【0026】
【発明の効果】
本発明によれば電池と電池接片との接触抵抗が低減する。従って、電池が消耗して来ても接触部の電圧降下が小さく、一方、カメラの低電圧作動性の改善向上と相俟って、従来に比し、撮影枚数が増加するという優れた効果を奏する。

BACKGROUND OF THE INVENTION
The present invention relates to a battery lid locking device for an electronic device or the like.
[0002]
[Prior art]
In a camera, a vertically long battery used as a power source is usually inserted from the bottom surface of the camera body exterior and is housed and arranged with the direction perpendicular to the bottom surface of the camera as an axis. The battery lid for closing the battery insertion opening is provided with a dedicated lock member in order to keep the lid in the closed position. When the battery is installed in the camera body, the battery cover is biased in the opening direction by the elastic force of the connecting piece of the battery having springiness, but the battery cover is moved to a predetermined closed position by the lock member. Is supposed to be retained.
[0003]
Since the lock mechanism for holding the battery cover in the closed position is configured by a dedicated member, the cost as a dedicated component is required. In addition, an arrangement space for the lock mechanism is required, and this arrangement space is one of the factors that increase the size of the battery housing portion.
[0004]
There is a battery lid for a camera that allows the battery lid to be easily opened even when the battery is not attached, and has improved operability. In this technology, a battery cover locking member is provided on the surface of the battery cover that covers the opening of the battery storage part, a normal battery connection contact piece is provided, and the battery cover is elastically deformed when the battery cover is closed. This is a technique for applying a biasing force in the opening direction to the lid (see, for example, Patent Document 1).
[0005]
This technique improves the difficulty of opening the lid when the battery is not stored, and is not a technique for improving the pressure between the battery electrode and the battery contact piece when the battery is stored.
[0006]
[Patent Document 1]
Japanese Patent Laid-Open No. 11-44908 (page 2-8, FIG. 4)
[0007]
[Problems to be solved by the invention]
When the battery is stored in the camera body, a battery contact piece is usually attached to the lid member. If the contact between the battery electrode and the battery contact piece is insufficient, an electrical resistance is generated in this portion, and the battery cannot be used up effectively. In recent years, the performance of the camera has been improved, and since it operates at a low voltage, the influence is particularly great.
[0008]
Therefore, by increasing the contact pressure of the battery, the contact resistance with the battery can be reduced and the number of shots can be increased. Conventionally, however, the contact between the electrode and the contact piece is made by a contact piece attached to the lid. Therefore, if the contact pressure is increased, the opening / closing operation force of the battery lid becomes too large and it is difficult to close the lid. There were drawbacks.
[0009]
An object of the present invention is to solve the above-mentioned problems and to provide a technique capable of increasing the contact pressure between a battery electrode and a contact piece without causing any difficulty in the opening / closing operation of the lid.
[0010]
[Means for Solving the Problems]
The present invention is a battery lid locking device characterized in that, in a device using a battery, a pressing means for pressing the battery is provided to the battery lid locking mechanism.
[0011]
More specifically, the pressing means is a protrusion provided on the back surface of the lid locking mechanism, and when the lid locking mechanism is locked, the protrusion moves forward to a position where the contact piece of the battery is pressed against the electrode to release the lock. Accordingly, the protrusion of the battery contact piece is retracted from the position where the battery contact piece is pressed against the electrode.
[0012]
The pressing means interlocks the battery lid locking mechanism and the battery contact piece to lock the battery contact piece and simultaneously bend the battery contact piece to increase the contact pressure with the battery. Thereby, only the battery contact pressure can be increased without increasing the opening / closing operation force of the battery lid.
[0013]
Another aspect of the pressing means is an elastic member provided on the back surface of the lid lock mechanism, and when the lid lock mechanism is locked, the elastic member presses the side portion of the battery to bring the battery into close contact with the battery chamber wall. In accordance with the unlocking, the pressing of the side portion of the battery is released, and the elastic member is separated from the battery.
[0014]
The conventional lid locking device only locks the battery lid, but other functions are added according to the present invention to become a multifunctional member.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
According to the present invention, when the battery lid is locked, the contact pressure of the battery contact piece is increased simultaneously with the operation, or the battery is pressed against the wall to prevent the battery from moving and the contact is stabilized, and the electric resistance of the contact portion is reduced. It is to reduce.
[0016]

A lid 52 of the storage chamber 51 in which the battery 50 is stored is attached to the main body cabinet 53 with a hinge structure. A battery lid locking device 10 is attached to the back surface of the lid 52. If the claw 11 of the locking device 10 is shifted in the direction of the arrow 12 after the lid 52 is closed, the tip 13 of the locking device 10 enters the lock hole 54 provided in the cabinet, and the lid 52 enters the closed lock state and cannot be opened. When the locking device 10 is shifted in the direction opposite to the arrow 12, the engagement between the tip of the locking device 10 and the lock hole 54 is released, and the lid 52 can be opened.
[0019]
In the present invention, the protrusion 14 is provided on the back surface of the lock device 10, and the protrusion 14 presses the contact piece 60 of the battery 50 when the lock device 10 is shifted in the direction of arrow 12 to be locked.
[0020]
FIG. 1 is an explanatory view showing the relationship between the locking device 10 and the contact piece 60. The contact piece 60 is attached to the back surface of the lid 52, and the contact portions 61 and 62 are in contact with the battery and are conducted. FIG. 1A shows a state before the locking device 10 is shifted in the direction of the arrow 12 in FIG. 2, and the height of the contact piece 60 (the distance between the back surface of the lid 52 and the contact) is a. The locking device 10 is not in a state of pushing the contact piece 60.
[0021]
FIG. 1B shows a state where the locking device 10 is shifted in the direction of the arrow 12 shown in FIG. 2, and shows a state where the projection 14 of the locking device 10 presses the contact piece 60. If the height of the protrusion 14 is b and the locking device 10 is in contact with the contact piece in the state of FIG. 1A, the contact piece is pressed by the protrusion height b, and as shown in FIG. The contact portion of the piece with the battery has a size approximately similar to (a + b).
[0022]

[0023]
Reference numerals 10 to 13 and 50 to 54 are the same as those in FIGS. The difference is that when the shaft 15 protrudes from the back surface of the locking device 10 and the elastic ring 16 is externally fitted to this shaft and the locking device 10 is shifted in the direction of the arrow 12, this elastic ring 16 has two batteries 50 and 50a. It is the point which pressed the side of. FIG. 5 is an explanatory diagram for explaining this operation, and shows the relationship between the two batteries 50 and 50 a and the elastic ring 16. Before the locking device 10 is shifted in the direction of arrow 12 in FIG. 4, the elastic ring is in the position 16a and is not in contact with the batteries 50 and 50a. When the locking device 10 is shifted in the direction of the arrow 12 (FIG. 4), the elastic ring 16a moves in the direction of the arrow 17 and is pressed to the position (16) in contact with the side surfaces of the two batteries, and the wedge between the batteries 50 and 50a. Bite into the gap.
[0024]
Therefore, the batteries 50 and 50a are strongly pressed against the side surface and are pressed and fixed to the wall surface in the battery chamber.
[0025]
With this fixing, the battery is stable against changes in the shooting posture, vibration, and the like, and the contact does not move. Therefore, the electrical resistance of the contact is stably maintained, and it operates even at a low voltage, contributing to the extension of the battery life.
[0026]
【The invention's effect】
According to the present invention, the contact resistance between the battery and the battery contact piece is reduced. Therefore, even if the battery is depleted, the voltage drop at the contact portion is small. On the other hand, combined with the improvement in the low voltage operability of the camera, the excellent effect of increasing the number of shots compared to the conventional case. Play.
