技術分野
本発明は、電子時計において電池を保持するための電池保持構造に関するものである。
背景技術
従来から、デジタル表示方式あるいはアナログ表示方式の電子時計において、駆動源として電池が使用されている。従来、電池を時計本体に取付ける方法として、電池を時計本体に組み込んだ後に、電池押え等の電池保持用の別部材を用いて電池を保持するようにしている。
第６図及び第７図に、電池押えを用いた従来の電子時計の電池保持構造を示す。ここで、第６図は電池保持構造周辺の平面図、第７図は第６図のＤ−Ｄ部分正断面図であり、同一部分には同一符号を付している。
第６図及び第７図において、４０１は電池、４０２は電池４０１より僅かに大径の開口部を有する樹脂製の電池枠、４０３は電池枠４０２とは別部材で構成された金属製の電池押え、４０４は電池枠４０２と一体に形成された庇部、４０５は正電極端子である。電池４０１を電池枠４０２内に取付ける場合には、電池４０１を、庇部４０４の下方に位置するように電池枠４０２の開口部内に収納した後、電池４０１の上側から電池押え４０３を電池枠４０２に取付ける。これにより、電池４０１は、電池枠４０２によって平面方向の位置ずれが防止され又、電池枠４０２、電池押え４０３及び庇部４０４によって挟持されて断面方向の位置ずれや脱落が防止される。尚、この状態では、電池４０１は正電極端子４０５と負電極端子（図示せず）に電気的に接触した状態に保持される。
以上のように、電池押え４０３を用いることにより、電池４０１の保持を行うことが可能になる。
しかしながら、前記構造では、電池４０１が断面方向に動かないようにするために、電池枠４０２とは別部品である電池押え４０３が必要となり又組立工数も多くなり、構成が複雑になると共に高価になるという問題があった。また、電池押え４０３を電池４０１に重ねて配設するため、電子時計の厚みが厚くなるという問題があった。
本発明は、簡単な構成で廉価に構成できる電子時計の電池保持構造を提供することを目的としている。また、本発明は、電子時計を薄型化可能にすることを目的としている。さらに、本発明は、電子時計が落下した際にも電池が位置ずれしないように確実に保持できるようにすることを目的としている。

即ち、本発明は、電池を保持するための開口部を備えた電池枠を有し、前記電池枠には、前記開口部側へ突出すると共にテーパが施された庇部を有する係合部が設けられていることを特徴とする電子時計の電池保持構造である。電池を開口部へ挿入して係合部の庇部により保持する。
ここで、前記係合部は複数設けられると共に、前記係合部の庇部は、電池取付時に前記電池が前記庇部の幅狭部に当接した後に幅広部に当接するような形状のテーパを施してもよい。
また、前記係合部は前記庇部と、前記庇部を前記電池枠に取付けるための弾性を有する腕部とにより構成してもよい。
さらに、前記電池枠及び係合部を、絶縁性樹脂によって一体形成してもよい。
さらにまた、前記庇部には、裏蓋を装着した状態で前記裏蓋に当接する突起部を一体形成するようにしてもよい。
また、前記突起部は、その少なくとも一部が前記係合部の内壁面よりも前記開口部側に突出するように構成され、前記内壁面よりも前記開口部側に突出した位置で前記裏蓋と当接するように構成してもよい。
また、前記電池はボタン電池であってもよい。
また、前記電子時計は、電子腕時計であってもよい。
発明を実施するための最良の形態
以下に、本発明に係る電子時計の電池保持構造の具体例について、図面を参照しながら詳細に説明する。
第１図は、本発明に係る電子時計の電池保持構造の一具体例を示す平面図で、電子腕時計の例を示している。また、第２図は、第１図のＡ−Ａ正断面図である。尚、第１図及び第２図においては、電池枠内に電池を保持した状態を示しており又、同一部分には同一符号を付している。
第１図及び第２図において、１０１は電池の一種であるボタン電池、１０２は電池１０１より僅かに大径の開口部１１３を有する絶縁性樹脂製の電池枠、１０３〜１０９は絶縁性樹脂を電池枠１０２と一体形成して構成された複数の係合部、１１０は正電極端子、１１１は電池枠１０２の底部に形成された穴１１２から突出するように付勢され弾性を有する負電極端子、１１４は巻真である。
係合部１０３〜１０９は、各々、開口部１１３側に突出し電池１０１の断面方向への位置ずれや脱落を防止する庇部１０３ａ〜１０９ａ、庇部１０３ａ〜１０９ａを電池枠１０２に連結すると共に電池１０１の平面方向の位置ずれを規制するための弾性を有する腕部１０３ｂ〜１０９ｂによって構成されている。
複数の係合部１０５〜１０８の庇部１０５ａ〜１０８ａは、電池１０１の取付時に、電池１０１が庇部１０５ａ〜１０８ａの幅狭部１０５ｃ〜１０８ｃに当接した後に幅広部１０５ｄ〜１０８ｄに当接するような形状にテーパが施されている。
尚、係合部１０９の庇部１０９ａはテーパは施されていない。また、係合部１０３、１０４の庇部１０３ａ、１０４ａはテーパが施されており、各々、幅狭部１０３ｃ、１０４ｃ、幅広部１０３ｄ、１０４ｄが形成されてるが、電池１０１の取付け当初に、電池１０１の一端部がこれらの庇部１０３ａ、１０４ａの下側に挿入されるものであるため、これらの庇部１０３ａ、１０４ａには必ずしもテーパを施す必要はない。
第３図は、電池枠１０２内に電池１０１を取付ける際の使用態様を示す正断面図で、第１図における電池枠１０２のＢ−Ｂ断面に相当する断面図を示している。
以下、第１図〜第３図を用いて、本具体例について詳細に説明する。
電池１０１を電池枠１０２内に取付ける場合には、先ず、予め定められた電池１０１の挿入方向、即ち、矢印Ｃ方向に沿って、電池１０１の一方の端縁部を、負電極端子１１１と係合部１０３、１０４の庇部１０３ａ、１０４ａ間に挿入し、電池枠１０２内周縁に当接させる（第３図参照）。
この状態で、電池１０１の他方の端縁部が係合部１０９の庇部１０９ａの下方に位置するように上から電池１０１を押圧する。電池１０１は、係合部１０５〜１０８の庇部１０５ａ〜１０８ａの幅狭部１０５ｃ〜１０８ｃから幅広部１０５ｄ〜１０８ｄに順に当接し、さらに電池１０１が押下されると、第２図の破線で示すように、電池１０１は電池枠１０２内で、係合部１０３〜１０９の庇部１０３ａ〜１０９ａの下部に入り込み、電池１０１は電池枠１０２の開口部１１３内に収容保持される。
このとき、庇部１０５ａ〜１０８ａにはテーパが施されているため、前記の如くして電池１０１を開口部１１３内に収容保持する際、電池１０１の周縁が庇部１０５ａ〜１０８ａに順に当接することによって、第２図の実線で示すように、弾性を有する腕部１０５ｂ〜１０８ｂが順に拡開するように撓み、庇部１０５ａ〜１０８ａも拡開する。これにより、容易に電池１０１を第１図及び第２図の保持位置に収容することが可能になる。電池１０１は電池枠１０２の開口部１１３内に収容保持され、電池１０１の正電極及び負電極が、各々、正電極端子１１０と負電極端子１１１に電気的に接触した状態に保持される。
このようにして電池枠１０２の開口部１１３内に保持されると、電池１０１は、平面方向の位置ずれは電池枠１０２の周壁部や係合部１０３〜１０９の腕部１０３ｂ〜１０９ｂによって防止されると共に、庇部１０３ａ〜１０９ａによって断面方向の位置ずれや脱落が防止される。
尚、電池１０１を交換する場合には、ピンセット等の工具を用いて、容易に電池１０１を取り外すことができる。
以上述べたように、本発明の一具体例に係る電子時計の電池保持構造は、特に、ボタン電池等の電池１０１を挿入保持するための開口部１１３を備えた電池枠１０２を有し、電池枠１０２には、開口部１１３側へ突出すると共にテーパが施された庇部１０５ａ〜１０８ａを有する係合部１０５〜１０８が形成されていることを特徴としている。
したがって、電池１０１の断面方向の動きを規制するための別個の部品を用いずに、落下等の衝撃が生じても電池１０１が外れることなく保持することが可能になり又、開口部１１３側に長く突出した庇部１０３ａ〜１０９ａに対して電池１０１の組み込み性が良いという効果を奏する。
また、部品点数の削減により構造を簡略化することが可能になり又、組立工数を削減できるため組立時間の短縮、ひいてはコストダウンを図ることが可能になる。
さらに、電池押え等の部品を電池１０１上に積層配設する必要がないため、電子時計を薄型化することが可能になる。
さらにまた、電池枠１０２及び庇部１０３〜１０９を絶縁性樹脂によって一体形成することにより、絶縁板等が不要になる。
尚、本具体例においては、電池１０１としてボタン電池１０１を使用したが、他の形状の電池を使用してもよい。また、電子腕時計の例で説明したが、デジタル表示式又はアナログ表示式の電子腕時計をはじめとして、壁掛け型電子時計、卓上型電子時計等の電池駆動型の各種電子時計にも適用することができる。
第４図は本発明に係る電子時計の電池保持構造の他の具体例を示す平面図で又、第５図は第４図のＥ−Ｅ正断面図である。尚、両図において、同一部分には同一符号を付すと共に、第１図〜第３図と同一部分には同一符号を付している。また、第４図は裏蓋を省略した図を示している。
本具体例と第１図〜第３図に示した具体例との相違点は、電池１０１の断面方向への位置ずれや脱落をより確実に防止するために、各庇部１０３ａ〜１０９ａに突起部５０１〜５０７を一体形成した点であり、電池１０１の挿入・保持方法その他は同一であるため、以下主として、複数の突起部５０１〜５０７について説明する。
第４図及び第５図において、各突起部５０１〜５０７は絶縁性樹脂によって形成されており、各庇部１０３ａ〜１０９ａの裏蓋６０１側に、各庇部１０３ａ〜１０９ａと一体に形成されている。突起部５０１〜５０７は、その先端部が円錐台に形成されており、裏蓋６０１に押圧された際にその先端部が潰れて、部品公差を吸収できるようになっている。また、突起部５０１〜５０７は、その少なくとも一部が、係合部１０３〜１０９の腕部１０３ｂ〜１０９ｂの内壁面６０２よりも開口部１１３側に突出するように構成され、内壁面６０２よりも開口部１１３側に突出した位置で裏蓋６０１と当接するように構成されている。また、電子時計の裏蓋６０１を装着することにより電子時計が完成した状態では、裏蓋６０１が突起部５０１〜５０７に当接するように構成されている。
上記構成において、電池１０１を電池枠の１０２の開口部１１３内に収容保持した状態で裏蓋６０１を電子時計本体に装着する場合、先ず、裏蓋６０１が突起部５０１〜５０７に当接する。この状態で、裏蓋６０１を電子時計本体に装着すると、裏蓋６０１は、突起部５０１〜５０７を押圧した状態で電子時計本体に装着される。このとき、突起部５０１〜５０７は、内壁面６０２よりも開口部１１３側に突出した位置で裏蓋６０１と当接するため、裏蓋６０１の押圧力によって庇部１０３ａ〜１０９ａは電池１０１方向に撓む。電池１０１は、電池枠１０２の開口部１１３内で庇部１０３ａ〜１０９ａによって押圧された状態で強固に保持される。
したがって、本具体例は前述した一具体例と同様の効果を有するばかりでなく、電池１０１の断面方向の動きを庇部１０３ａ〜１０９ａによって確実に規制することが可能になるため、電子時計が落下した場合等のように衝撃を受けた場合でも、電池１０１に位置ずれや脱落が生じることをより確実に防止できる。
また、突起部５０１〜５０７は、内壁面６０２よりも開口部１１３側に突出した位置で裏蓋６０１と当接するため、庇部１０３ａ〜１０９ａを確実に電池１０１側へ押圧でき、電池１０１の保持をより確実に行うことが可能になる。したがって、耐衝撃性に優れた電子時計を構成することが可能になる。
尚、突起部５０１〜５０７は、必ずしも全ての庇部１０３ａ〜１０９ａに設ける必要はなく、少なくとも３つの突起部をバランスよく配設すればよい。また、突起部５０１〜５０７は、各庇部１０３ａ〜１０９ａに複数個ずつ配設するようにしてもよい。さらに、突起部５０１〜５０７を、内壁面６０２よりも開口部１１３側に突出しないように構成して、内壁面６０２から開口部１１３側に突出しない位置で裏蓋６０１と当接するように構成することも可能である。この場合にも、裏蓋６０１の押圧力によって腕部１０３ｂ〜１０９ｂが撓んで庇部１０３ａ〜１０９ａが電池１０１に押圧され、これによって電池１０１の断面方向の位置ずれ等が防止される。

The electronic timepiece may be an electronic wristwatch.
BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a specific example of a battery holding structure of an electronic timepiece according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a plan view showing a specific example of a battery holding structure of an electronic timepiece according to the present invention, and shows an example of an electronic wristwatch. FIG. 2 is a front sectional view taken along the line AA in FIG. 1 and 2 show a state in which the battery is held in the battery frame, and the same portions are denoted by the same reference numerals.
1 and 2, 101 is a button battery which is a kind of battery, 102 is a battery frame made of an insulating resin having an opening 113 having a diameter slightly larger than that of the battery 101, and 103 to 109 are insulating resins. A plurality of engaging portions formed integrally with the battery frame 102, 110 is a positive electrode terminal, 111 is a negative electrode terminal that is urged to protrude from a hole 112 formed in the bottom of the battery frame 102 and has elasticity , 114 is a winding stem.
The engaging portions 103 to 109 project to the opening 113 side and connect the flange portions 103a to 109a and the flange portions 103a to 109a that prevent the displacement and dropout of the battery 101 in the cross-sectional direction to the battery frame 102 and the battery. It is comprised by the arm parts 103b-109b which have the elasticity for controlling the position shift of the plane direction of 101. As shown in FIG.
The flange portions 105a to 108a of the plurality of engaging portions 105 to 108 come into contact with the wide portions 105d to 108d after the battery 101 contacts the narrow portions 105c to 108c of the flange portions 105a to 108a when the battery 101 is attached. The shape is tapered.
Note that the flange 109a of the engaging portion 109 is not tapered. Further, the flange portions 103a and 104a of the engaging portions 103 and 104 are tapered, and the narrow portions 103c and 104c and the wide portions 103d and 104d are formed respectively. Since one end of 101 is inserted below the flanges 103a and 104a, the flanges 103a and 104a do not necessarily need to be tapered.
FIG. 3 is a front sectional view showing a usage mode when the battery 101 is mounted in the battery frame 102, and shows a sectional view corresponding to the BB section of the battery frame 102 in FIG.
Hereinafter, this specific example will be described in detail with reference to FIGS. 1 to 3.
When mounting the battery 101 in the battery frame 102, first, one end edge of the battery 101 is engaged with the negative electrode terminal 111 along the predetermined insertion direction of the battery 101, that is, the direction of arrow C. It inserts between the collar parts 103a and 104a of the joint parts 103 and 104, and contact | abuts to the inner periphery of the battery frame 102 (refer FIG. 3).
In this state, the battery 101 is pressed from above so that the other edge portion of the battery 101 is positioned below the flange 109 a of the engaging portion 109. The battery 101 sequentially contacts the wide portions 105d to 108d from the narrow portions 105c to 108c of the flange portions 105a to 108a of the engaging portions 105 to 108, and when the battery 101 is further pressed, it is indicated by a broken line in FIG. As described above, the battery 101 enters the lower part of the flanges 103 a to 109 a of the engaging portions 103 to 109 in the battery frame 102, and the battery 101 is accommodated and held in the opening 113 of the battery frame 102.
At this time, since the flanges 105a to 108a are tapered, when the battery 101 is accommodated and held in the opening 113 as described above, the peripheral edge of the battery 101 sequentially contacts the flanges 105a to 108a. Accordingly, as shown by the solid line in FIG. 2, the elastic arm portions 105b to 108b are bent so as to expand in order, and the flange portions 105a to 108a are also expanded. Thereby, the battery 101 can be easily accommodated in the holding position shown in FIGS. 1 and 2. The battery 101 is housed and held in the opening 113 of the battery frame 102, and the positive electrode and the negative electrode of the battery 101 are held in a state of being in electrical contact with the positive electrode terminal 110 and the negative electrode terminal 111, respectively.
When the battery 101 is held in the opening 113 of the battery frame 102 in this manner, the positional displacement of the battery 101 in the planar direction is prevented by the peripheral wall portion of the battery frame 102 and the arm portions 103b to 109b of the engagement portions 103 to 109. At the same time, the flanges 103a to 109a prevent the displacement and dropout in the cross-sectional direction.
When the battery 101 is replaced, the battery 101 can be easily removed using a tool such as tweezers.
As described above, the battery holding structure of the electronic timepiece according to one specific example of the present invention has the battery frame 102 including the opening 113 for inserting and holding the battery 101 such as a button battery, and the battery The frame 102 is formed with engaging portions 105 to 108 that have flanges 105a to 108a that protrude toward the opening 113 and are tapered.
Therefore, the battery 101 can be held without being detached even if an impact such as dropping occurs without using a separate component for regulating the movement of the battery 101 in the cross-sectional direction. There is an effect that the battery 101 can be easily incorporated into the long protruding flanges 103a to 109a.
Further, the structure can be simplified by reducing the number of parts, and the number of assembling steps can be reduced, so that the assembling time can be shortened and the cost can be reduced.
Furthermore, since it is not necessary to stack and arrange parts such as a battery retainer on the battery 101, the electronic timepiece can be thinned.
Furthermore, by integrally forming the battery frame 102 and the flanges 103 to 109 with an insulating resin, an insulating plate or the like is not necessary.
In this specific example, the button battery 101 is used as the battery 101, but batteries of other shapes may be used. In addition, although the example of the electronic wristwatch has been described, the present invention can be applied to various battery-driven electronic timepieces such as a wall-mounted electronic timepiece and a desk-top type electronic timepiece as well as a digital display type or analog display type electronic wristwatch. .
FIG. 4 is a plan view showing another specific example of the battery holding structure of the electronic timepiece according to the present invention, and FIG. 5 is a EE front sectional view of FIG. In both figures, the same parts are denoted by the same reference numerals, and the same parts as those in FIGS. 1 to 3 are denoted by the same reference numerals. FIG. 4 shows a view in which the back cover is omitted.
The difference between this example and the example shown in FIGS. 1 to 3 is that protrusions are formed on the flanges 103a to 109a in order to more reliably prevent displacement and dropout of the battery 101 in the cross-sectional direction. Since the parts 501 to 507 are integrally formed and the method for inserting and holding the battery 101 is the same, the plurality of protrusions 501 to 507 will be mainly described below.
4 and 5, the protrusions 501 to 507 are made of an insulating resin, and are formed integrally with the flanges 103a to 109a on the back cover 601 side of the flanges 103a to 109a. Yes. The protrusions 501 to 507 are formed in a truncated cone at the tip, and when the back cover 601 is pressed, the tip is crushed to absorb the component tolerance. Further, the protrusions 501 to 507 are configured such that at least a part thereof protrudes toward the opening 113 side from the inner wall surface 602 of the arm portions 103 b to 109 b of the engaging portions 103 to 109, and more than the inner wall surface 602. It is configured to abut against the back cover 601 at a position protruding toward the opening 113 side. In addition, when the electronic timepiece is completed by attaching the back cover 601 of the electronic timepiece, the back cover 601 is configured to abut against the protrusions 501 to 507.
In the above configuration, when the back cover 601 is attached to the electronic timepiece main body while the battery 101 is housed and held in the opening 113 of the battery frame 102, the back cover 601 first comes into contact with the protrusions 501 to 507. When the back cover 601 is attached to the electronic timepiece main body in this state, the back cover 601 is attached to the electronic timepiece main body in a state where the projections 501 to 507 are pressed. At this time, since the protrusions 501 to 507 come into contact with the back cover 601 at a position protruding from the inner wall surface 602 to the opening 113 side, the flange parts 103a to 109a are bent toward the battery 101 by the pressing force of the back cover 601. Mu The battery 101 is firmly held in a state in which the battery 101 is pressed by the flanges 103 a to 109 a in the opening 113 of the battery frame 102.
Therefore, this specific example not only has the same effect as the one specific example described above, but also allows the movement of the battery 101 in the cross-sectional direction to be reliably regulated by the flanges 103a to 109a, so that the electronic timepiece falls. Even when an impact is applied, such as when the battery 101 is subjected to an impact, the battery 101 can be more reliably prevented from being displaced or dropped.
In addition, since the protrusions 501 to 507 are in contact with the back cover 601 at a position protruding toward the opening 113 from the inner wall surface 602, the flanges 103a to 109a can be reliably pressed toward the battery 101 and the battery 101 is held. Can be performed more reliably. Therefore, an electronic timepiece having excellent impact resistance can be configured.
Note that the protrusions 501 to 507 are not necessarily provided on all the flanges 103a to 109a, and at least three protrusions may be arranged in a balanced manner. Further, a plurality of protrusions 501 to 507 may be arranged on each of the flanges 103a to 109a. Further, the protrusions 501 to 507 are configured so as not to protrude from the inner wall surface 602 to the opening 113 side, and are configured to contact the back cover 601 at a position not protruding from the inner wall surface 602 to the opening 113 side. It is also possible. Also in this case, the arm portions 103b to 109b are bent by the pressing force of the back cover 601, and the collar portions 103a to 109a are pressed against the battery 101, thereby preventing the positional deviation of the battery 101 in the cross-sectional direction.
Industrial Applicability As described above, the battery holding structure of the electronic timepiece according to the present invention is driven by a battery such as a digital display type or an analog display type electronic wristwatch, a wall-mounted type electronic timepiece, or a desktop type electronic timepiece. Applicable to various types of electronic watches.
