Description

本発明は、他の部材に弾性接触するバネ部材などの組込み構造に関する発明であって、例えば、太陽電池時計のソーラーセルと回路基板の電気接続に使用する接点バネや、時計の歯車の位置を規制する躍制部材などに最適な構造である。 The present invention relates to a built-in structure such as a spring member that elastically contacts other members. For example, the position of a contact spring used for electrical connection between a solar cell of a solar cell watch and a circuit board and a gear of a watch It is the most suitable structure to control the leaping control member.

従来から太陽電池時計のソーラーセルと回路基板を電気接続する構造としては2つの構造があった。一つは接点バネを使用する構造であり、もう一つは可撓性の接続部材を使用する構造であった。 Conventionally, there are two structures for electrically connecting a solar cell of a solar cell watch and a circuit board. One is a structure using a contact spring, and the other is a structure using a flexible connecting member.

文字板と、時計駆動部と、発電面に出力端子を有し、時計駆動部の動力源となる電力を発生させる太陽電池と、太陽電池の出力端子と回路基板を導通させる為の接点バネと、太陽電池の発電面が文字板表面に向きながら、文字板の外周部に環状に配置された時計は従来から特許文献1に提案されている。 A dial plate, a timepiece drive unit, a solar cell having an output terminal on the power generation surface and generating power as a power source of the timepiece drive unit, and a contact spring for electrically connecting the output terminal of the solar cell and the circuit board Patent Document 1 has conventionally proposed a timepiece that is annularly arranged on the outer peripheral portion of a dial plate while the power generation surface of the solar cell faces the dial surface.

また、接点バネではなく、太陽電池の出力端子に可撓性の接続部材を熱圧着し、それを時計駆動部の回路基板へ接続させる構造が特許文献2に提案されている。 Further, Patent Document 2 proposes a structure in which a flexible connecting member is thermocompression bonded to an output terminal of a solar cell, not a contact spring, and is connected to a circuit board of a timepiece driving unit.

特開2003−130974号公報(図1)Japanese Patent Laying-Open No. 2003-130974 (FIG. 1) WO2004/066042(図1、図6)WO2004 / 066042 (FIGS. 1 and 6)

特許文献1の図1のような構造とすることにより、接点バネを使用してリング状に太陽電池を配置した太陽電池時計を作ることが可能である。 By adopting the structure as shown in FIG. 1 of Patent Document 1, it is possible to make a solar cell timepiece in which solar cells are arranged in a ring shape using contact springs.

しかしながら、特許文献1の構造は以下のような問題点を有する。
接点バネを用いて太陽電池と回路基板の導通を取る構造は、太陽電池が先に組まれた状態で接点バネを組むと、接点バネを太陽電池に当て込みながら接点バネの位置決め用突起部に接点バネの固定部を入れ込むことになるため、組み難く、接点バネによって太陽電池を傷付けてしまう可能性があった。
However, the structure of Patent Document 1 has the following problems.
The structure that uses a contact spring to connect the solar cell to the circuit board is that when the contact spring is assembled in the state where the solar cell is assembled first, the contact spring is applied to the positioning protrusion of the contact spring while being applied to the solar cell. Since the fixed portion of the contact spring is inserted, it is difficult to assemble, and the solar cell may be damaged by the contact spring.

また逆に、接点バネを先に組まれた状態で、太陽電池を後から組み込む場合は、接点バネの接点部が太陽電池に接触しないように手で撓ませながら太陽電池をリング状に組む必要があったため、大変組み難かった。即ち、接点バネ構造は、組立作業性に問題があった。 Conversely, if the solar cell is assembled later with the contact spring assembled first, it is necessary to assemble the solar cell in a ring shape while flexing by hand so that the contact portion of the contact spring does not contact the solar cell. Because it was, it was very difficult to assemble. That is, the contact spring structure has a problem in assembling workability.

一方、特許文献2の図1にあるような太陽電池の出力端子に可撓性の接続部材を熱圧着した部品構成で、特許文献2の図6にある構造とした場合は、特許文献1の構造よりも組立作業性が改善される。 On the other hand, in the case where the structure shown in FIG. 6 of Patent Document 2 is formed by thermocompression bonding of a flexible connecting member to the output terminal of the solar cell as shown in FIG. The assembly workability is improved over the structure.

しかしながら、特許文献2の構造は以下のような問題点を有する。
太陽電池に可撓性の接続部材を熱圧着し、それを時計駆動部の回路基板へ接続させる構造は、回路基板と太陽電池を接続部材で直接繋げている関係上、FPC基板のような可撓性の
あるフレキシブルな接続部材ではないと成り立たなくなる。
この場合、接続部材単体のコストが高くなってしまい、更に太陽電池と接続部材の熱圧着工程が入るため、太陽電池回りのコストが上がってしまう。
However, the structure of Patent Document 2 has the following problems.
The structure in which a flexible connection member is thermocompression bonded to the solar cell and connected to the circuit board of the timepiece drive unit is possible because the circuit board and the solar cell are directly connected by the connection member. If it is not a flexible connecting member with flexibility, it will not hold.
In this case, the cost of the connecting member alone is increased, and further, the thermocompression bonding process of the solar cell and the connecting member is performed, so that the cost around the solar cell is increased.

また、接続部材を回路基板にネジなどで接続固定させる構造は、ネジの緩みによって接点バネの様に安定した接点圧が取れないことがあるため、電気的接点が安定しない問題があり、構造上工夫する必要があった。 In addition, the structure in which the connection member is connected and fixed to the circuit board with a screw or the like may not be able to obtain a stable contact pressure like a contact spring due to the looseness of the screw. It was necessary to devise.

本発明は、上記のような太陽電池時計において、コストと安定した接点を確保するため、接点バネで導通させるような構造を採用したとき、先に組んだ太陽電池を傷付けることが無く、後から容易に接点バネを組むことが出来る構造を提供する。 In the solar cell watch as described above, in order to secure a cost and a stable contact, when adopting a structure that conducts with a contact spring, the previously assembled solar cell is not damaged, and later A structure capable of easily assembling a contact spring is provided.

また、歯車に対する側圧バネの構造や躍制バネの構造でも同様な構造を用いることで、側圧バネの構造や躍制バネの構造でも組立作業性の効率アップを図ることを目的としている。 Another object of the present invention is to improve the efficiency of assembly workability even in the structure of the side pressure spring or the structure of the spring spring by using the same structure as the structure of the side pressure spring or the spring spring for the gear.

Further, when the positioning hole is provided only at one place, it is desirable to provide protrusions such as the restricting protrusions 33a and 33b shown in FIG. 2b on the mounting surface 31 so that the position of the component does not shift.

The solar cell 40 is shown on the A end side, but the B end side is not shown. 3 and 4, as shown in FIG. 3, the solar cell mounting groove 91 is arranged on the solar cell base 90 so that the solar cell 40 can be assembled on the dial 100 side. As shown in FIG. 4, the L-shaped configuration is adopted so that the electrode portion 41 is brought out to the back cover side as shown in FIG.

次に実施例1における接点バネ50の組込み手順を説明する。
図7〜図10は接点バネの組込み手順を示した実施例1の時計の要部断面図である。図7から図10は、図中上が裏蓋側がであり、図中下が時刻表示部側になっている。
Next, a procedure for incorporating the contact spring 50 in the first embodiment will be described.
7 to 10 are cross-sectional views of a main part of the timepiece according to the first embodiment showing the procedure for assembling the contact spring. 7 to 10, the upper side in the figure is the case back side, and the lower side in the figure is the time display unit side.

接点バネ50が組まれる前の時計の状態を断面図で図7に示す。
接点バネ50よりも先に、地板10と、時計駆動部の回路基板20と、基台30と、太陽電池基台90と、太陽電池40と、スペーサ110と、時計の文字板100と、透明リング120とを組まれた状態にする。
FIG. 7 is a cross-sectional view of the timepiece before the contact spring 50 is assembled.
Prior to the contact spring 50, the base plate 10, the circuit board 20 of the timepiece driving unit, the base 30, the solar cell base 90, the solar cell 40, the spacer 110, the timepiece dial 100, and the transparent The ring 120 is assembled.

次に接点バネ50が組まれる過程を図8、図9に示す。
図示しているように、接点バネ50が有する位置決め穴52a、つまり基部51を基台30が有する位置決め突起部32の突出方向に対して正対させず斜めに傾けた状態のまま係合させながら組み込む。こうすることにより、太陽電池40の電極部41に接点バネ50の接点部54を作用させることなく、組むことが可能となる。この場合の作用させないと
いう意味は、接点バネ50の接点部54が太陽電池40の電極部41に軽く接触するか、または接触しないで離間した状態であって、確実な接触でない状態を意味している。
この際、接点バネ50の位置決め穴52a(52b)の穴径は図2cのように、基台30の位置決め突起部32の径よりも少し大きくすることで、斜めに組み込まれた際に、基台30の突起部32が接点バネ50の位置決め穴52a(52b)の穴縁部55a(55b)に引っ掛らないようにすることが重要である。
Next, the process of assembling the contact spring 50 is shown in FIGS.
As shown in the figure, the positioning hole 52a of the contact spring 50, that is, the base 51 is engaged with the base 51 in an inclined state without being opposed to the protruding direction of the positioning protrusion 32 of the base 30. Include. By doing so, it becomes possible to assemble the contact part 54 of the contact spring 50 without acting on the electrode part 41 of the solar cell 40. The meaning of not acting in this case means that the contact portion 54 of the contact spring 50 is in light contact with the electrode portion 41 of the solar cell 40 or is separated without contact, and is not in reliable contact. Yes.
At this time, the hole diameter of the positioning hole 52a (52b) of the contact spring 50 is slightly larger than the diameter of the positioning protrusion 32 of the base 30 as shown in FIG. It is important that the protrusion 32 of the base 30 is not caught by the hole edge 55a (55b) of the positioning hole 52a (52b) of the contact spring 50.

前述のように接点バネ50を組込む際には、接点バネ50の接点部54が太陽電池40の電極部41に対して軽く当接して組まれても、または離間して組まれても、太陽電池40の電極部41に接点バネ50の接点圧が掛からなければ、組み込み作業性の効果に差異はない。 As described above, when assembling the contact spring 50, the contact portion 54 of the contact spring 50 is assembled lightly against the electrode portion 41 of the solar cell 40, or assembled separately. If the contact pressure of the contact spring 50 is not applied to the electrode part 41 of the battery 40, there is no difference in the effect of the assembly workability.

接点バネ50はその重心の位置を工夫することにより組み込みをより容易にすることができる。例えば接点バネ50の重心が基部51側にあった場合は、接点バネ50を基台30の搭載面31の縁34に到達した位置(図9)まで組むと、基台30の搭載面31の縁34を支点とし、接点バネ50の弾性部53に設けられた接点部54が、太陽電池40(本発明の電気部品に相当する)の電極部41に軽く当接して、傾いた状態を維持することが可能となる。つまり接点バネ50の接点部54が太陽電池40の電極部41の近くに位置するまでは接点バネ50の基部51を斜めに傾けて組み込む必要がある。但し、接点バネ50の接点部54に接触したあとは、基部51が自重で基台30の搭載面31に対して水平にもどろうとするので、後での固定がしやすいという効果がある。 The contact spring 50 can be more easily assembled by devising the position of its center of gravity. For example, when the center of gravity of the contact spring 50 is on the base 51 side, when the contact spring 50 is assembled to the position (FIG. 9) that reaches the edge 34 of the mounting surface 31 of the base 30, Using the edge 34 as a fulcrum, the contact portion 54 provided on the elastic portion 53 of the contact spring 50 is in light contact with the electrode portion 41 of the solar cell 40 (corresponding to the electric component of the present invention), and maintains an inclined state. It becomes possible to do. That is, until the contact portion 54 of the contact spring 50 is positioned near the electrode portion 41 of the solar cell 40, the base portion 51 of the contact spring 50 needs to be inclined and assembled. However, after contacting the contact portion 54 of the contact spring 50, the base portion 51 tends to return to the mounting surface 31 of the base 30 by its own weight, so that there is an effect that it can be easily fixed later.

一方、弾性部53と接点部54側に重心がある場合は、基台30の搭載面31の縁34を支点とし、接点バネ50の位置決め穴52a(52b)の穴縁部55a(55b)が基台30の位置決め突起部32の側面に引っ掛り、基部51が傾いて弾性部53の接点部54は太陽電池40の電極部41から離れる方向に移動しやすいので、基台30の位置決め突起部32に基部51の位置決め穴52a(52b)が自然と斜めに傾斜して入れやすくなり、組込みしやすくなる。 On the other hand, when the center of gravity is on the elastic portion 53 and the contact portion 54 side, the edge 34 of the mounting surface 31 of the base 30 is used as a fulcrum, and the hole edge 55a (55b) of the positioning hole 52a (52b) of the contact spring 50 is formed. Since the base portion 51 is inclined and the contact portion 54 of the elastic portion 53 is easily moved away from the electrode portion 41 of the solar cell 40 by being caught on the side surface of the positioning projection portion 32 of the base 30, the positioning projection portion of the base 30 The positioning holes 52a (52b) of the base 51 are easily inclined at 32 and can be easily assembled.

このように接点バネ50の重心がどちらに有っても、それぞれ作業性に有利な効果があるので、接点バネ50の重心の位置は適宜選択して使用することができる。 In this way, regardless of the center of gravity of the contact spring 50, there is an advantageous effect on workability. Therefore, the position of the center of gravity of the contact spring 50 can be appropriately selected and used.

次に接点バネ50の組み込み完了後を図10に示す。接点バネ50が図9の位置まで組まれた後、接点バネ50と接点バネ押さえ60とをショートさせない為の絶縁シート70を組み、次にそれらを押さえる為の接点バネ押さえ60を組み、更にこれらを固定させるために、接点バネ押さえねじ80を組む。
これにより、斜めに傾いていた接点バネ50の基部51が基台30の搭載面31と正対する形となるため、太陽電池40の電極部41に作用していなかった接点バネ50の接点部54が電極部41に圧接して弾力的に作用することになり、太陽電池40から出力される電力を接点バネ50に導通することができる。
Next, FIG. 10 shows after the contact spring 50 has been assembled. After the contact spring 50 is assembled to the position shown in FIG. 9, an insulating sheet 70 is assembled to prevent the contact spring 50 and the contact spring retainer 60 from being short-circuited, and then a contact spring retainer 60 is assembled to retain them. In order to fix the contact spring, the contact spring holding screw 80 is assembled.
As a result, the base 51 of the contact spring 50 that is inclined obliquely faces the mounting surface 31 of the base 30, so that the contact 54 of the contact spring 50 that did not act on the electrode portion 41 of the solar cell 40. Is pressed against the electrode portion 41 and acts elastically, and the electric power output from the solar cell 40 can be conducted to the contact spring 50.

また、接点バネ50の回路接点部56も時計駆動部の回路基板20と圧接するため、接点バネ50に導通した太陽電池40から出力された電力を時計駆動部の回路基板20に伝えることが可能となる。
そしてこの時計ムーブメント130を外装ケース140に入れると図1の完成時計となる
Further, since the circuit contact portion 56 of the contact spring 50 is also in pressure contact with the circuit board 20 of the timepiece drive unit, it is possible to transmit the power output from the solar cell 40 conducted to the contact spring 50 to the circuit board 20 of the timepiece drive unit. It becomes.
When the timepiece movement 130 is put in the outer case 140, the completed timepiece shown in FIG. 1 is obtained .

〔実施例2〕

[Example 2]
Next, a second embodiment of the present invention will be described. FIG. 11 a is a plan view of the watch of Example 2 as seen from the back cover side;
FIG. 11b is an enlarged plan view of a contact portion connecting the electrode portion of the solar cell and the circuit board of the timepiece driving portion, and FIG. It is. FIG. 12 is a cross-sectional view of a main part in which the assembly of the contact spring related parts of Example 1 is completed, and FIG. 13 is a cross-sectional view of a main part showing the timepiece movement shown in FIG.

実施例2の時計は、実施例1の時計よりも時刻表示面積が広くなって、環状に配置された太陽電池40の配置位置が実施例1の場合よりも時計ムーブメント130からさらに外側に配置された構造になっている。
そのため、接点バネ50は位置決め穴52bを位置決め突起部32に係合させることにより、接点部54の位置を実施例1のときよりも外側に移動させている。位置決め穴52bは位置決め穴52aより奥側にあるので、接点バネ50の接点部54がさらに外側へ移動するので、太陽電池40の電極部41と接触させることができる。
これにより、外側へ移動した太陽電池40の電極部41と圧接できるようになっている。なお、接点バネ50の組み立て手順などは実施例1と同様なので省略する。
The timepiece of the second embodiment has a larger time display area than the timepiece of the first embodiment, and the arrangement position of the annularly arranged solar cells 40 is arranged further outward from the timepiece movement 130 than in the case of the first embodiment. It has a structure.
Therefore, the contact spring 50 moves the position of the contact portion 54 to the outside than in the first embodiment by engaging the positioning hole 52b with the positioning protrusion 32. Since the positioning hole 52b is located behind the positioning hole 52a, the contact portion 54 of the contact spring 50 moves further outward, so that it can be brought into contact with the electrode portion 41 of the solar cell 40.
Thereby, it can come in pressure contact with the electrode part 41 of the solar cell 40 moved to the outside. The assembly procedure of the contact spring 50 is the same as that in the first embodiment, and will not be described.

〔変形例〕
上記実施例1、2では、基台30の位置決め突起部32が1つの接点バネ50に対し、1箇所しか設けていないが、図14a,図14bのように、1つの接点バネに2箇所以上の位置決め突起部32a,32bを係合させて位置決めさせることも可能である。
[Modification]
In the first and second embodiments, the positioning protrusion 32 of the base 30 is provided only at one location for one contact spring 50. However, as shown in FIGS. 14a and 14b, two or more locations are provided on one contact spring. The positioning protrusions 32a and 32b can be engaged and positioned.

また、位置決め穴を2箇所設ける場合は、図14a,図14bの様に、位置決め穴52を3つ(52a〜52c)用意する事で、図14aの位置決め穴52a、位置決め穴52b、図14bの位置決め穴52b、位置決め穴52cの組合せで、位置決め穴が1つの物と同様に使用出来る。 When two positioning holes are provided, three positioning holes 52 (52a to 52c) are prepared as shown in FIGS. 14a and 14b, so that the positioning holes 52a, 52b, and 14b of FIG. 14a are prepared. By combining the positioning hole 52b and the positioning hole 52c, the positioning hole can be used in the same manner as a single object.

〔実施例3〕
次に本発明の実施例3を図15aから図16bに基づいて説明する。
図15aは時計の歯車のバックラッシを詰めるために、歯車の一つに一定の負荷を与える側圧バネ機構を示した平面図であり、側圧バネが側圧を受ける対象の作動車に掛かっている状態を示した平面図である。図15bは図15aの断面図である。図16a側圧バネを組込む手順を示した平面図、図16bはその断面図である。
Example 3
Next, a third embodiment of the present invention will be described with reference to FIGS. 15a to 16b.
FIG. 15a is a plan view showing a side pressure spring mechanism that applies a constant load to one of the gears in order to close backlash of the gear of the watch, and shows a state in which the side pressure spring is applied to the target operating vehicle that receives the side pressure. It is the shown top view. FIG. 15b is a cross-sectional view of FIG. 15a. FIG. 16A is a plan view showing a procedure for incorporating the side pressure spring, and FIG. 16B is a sectional view thereof.

図15a、図15bにおいて、230は各構成部品を組み込むための基台、220は図示していない指針や円板が取り付けられる表示車、240は表示車220を作動させる作動車、250は作動車240のバックラッシ詰めを行うための側圧バネ、260は側圧バネ250を押さえる側圧バネ押さえで構成される。本実施例では、側圧バネ250が本発明の作用部品に相当し、作動車240が他の部品に相当する。 15a and 15b, 230 is a base for incorporating each component, 220 is a display wheel to which a pointer or disk not shown is attached, 240 is an operating vehicle for operating the display wheel 220, and 250 is an operating vehicle. A side pressure spring 260 for performing backlash packing 240 is constituted by a side pressure spring presser for pressing the side pressure spring 250. In this embodiment, the side pressure spring 250 corresponds to the working part of the present invention, and the operating wheel 240 corresponds to other parts.

側圧バネ250は基部251を有し、その基部251には2つの位置決め穴252aと位置決め異形穴252bが設けられている。さらに基部251からは、下方向に折り曲げられ、平面方向に弾性を有する弾性部253を有し、その弾性部253の先端には、作動車240を側圧する側圧部254を有している。 The side pressure spring 250 has a base 251, and the base 251 is provided with two positioning holes 252 a and a positioning irregular hole 252 b. Further, the base 251 has an elastic part 253 that is bent downward and has elasticity in the plane direction, and has a side pressure part 254 that laterally pressurizes the operating wheel 240 at the tip of the elastic part 253.

基台230は側圧バネ250の基部251を搭載する搭載面231を有し、その搭載面231には位置決め突起232a,232bと、搭載面231に側圧バネ250が組まれたときに側圧バネ250の基部251の平面方向を規制する規制突起部233a〜233dを有している。さらに搭載面231から一段下がった位置には、側圧バネ250から側圧を受ける作動車240を搭載する作動車搭載面234を有し、その作動車搭載面234には作動車240用の回転軸235を有している。この場合、作動車240は位置決め突起
232a,232bの近辺に配置されている。
なお、側圧バネ250の位置決め穴252は本実施例の様な丸穴や異形状穴だけでなく、角穴,楕円穴,長穴,切り欠き形状等でもよい。
The base 230 has a mounting surface 231 on which the base 251 of the side pressure spring 250 is mounted. On the mounting surface 231, positioning protrusions 232 a and 232 b and the side pressure spring 250 when the side pressure spring 250 is assembled on the mounting surface 231. It has the regulation projection parts 233a-233d which regulate the plane direction of the base 251. Further, a position lower than the mounting surface 231 has an operating vehicle mounting surface 234 for mounting the operating vehicle 240 that receives the side pressure from the side pressure spring 250, and the operating vehicle mounting surface 234 has a rotating shaft 235 for the operating vehicle 240. have. In this case, the operating wheel 240 is disposed in the vicinity of the positioning protrusions 232a and 232b.
The positioning hole 252 of the side pressure spring 250 is not limited to a round hole or irregularly shaped hole as in this embodiment, but may be a square hole, an elliptical hole, a long hole, a notch shape, or the like.

側圧バネ250の組込み手順は、前述した実施例1の接点バネとほぼ同じだが、簡単に説明する。図16a、図16bにおいて、基台230に対して先に表示車220と作動車240とを組込みその後で側圧バネ250を組込む。 The procedure for assembling the side pressure spring 250 is almost the same as that of the contact spring of the first embodiment, but will be described briefly. In FIGS. 16a and 16b, the display wheel 220 and the operating wheel 240 are first assembled to the base 230, and then the side pressure spring 250 is assembled.

この際に、側圧バネ250を有する位置決め穴252aと位置決め異形穴252bとを基台230が有する位置決め突起部232a,232bの突出方向に対して正対させず斜めに傾けた状態のまま係合させながら組む。言い換えると、位置決め突起部232a、232bが形成された搭載面231に対して、側圧バネ250の基部251を正対させないで斜めに傾けて組み込む。傾ける方向は、作動車240の配置方向で、こうすることで作動車240の歯車部241に側圧バネ250の側圧部254を作用させることなく、組む込むことが可能となる。 At this time, the positioning hole 252a having the side pressure spring 250 and the positioning deformed hole 252b are engaged with each other while being obliquely inclined without facing to the protruding direction of the positioning protrusions 232a and 232b of the base 230. While assembling. In other words, the base portion 251 of the lateral pressure spring 250 is tilted and assembled with respect to the mounting surface 231 on which the positioning protrusions 232a and 232b are formed without facing the mounting surface 231. The direction of tilting is the direction in which the working wheel 240 is arranged. In this way, the working wheel 240 can be assembled without causing the side pressure portion 254 of the side pressure spring 250 to act on the gear portion 241 of the working wheel 240.

この際に、側圧バネ250の位置決め穴252aと位置決め異形穴252bの穴径は、基台230の位置決め突起部232a,232bの径よりも少し大きくすることで、斜めに組み込まれた際に、基台230の位置決め突起部232a,232bが側圧バネ250の位置決め穴252aと位置決め異形穴252bの穴縁に引っ掛らないようにすることが重要である。 At this time, the hole diameters of the positioning hole 252a and the positioning deformed hole 252b of the side pressure spring 250 are slightly larger than the diameters of the positioning protrusions 232a and 232b of the base 230, so It is important that the positioning protrusions 232a and 232b of the base 230 are not caught by the hole edges of the positioning hole 252a and the positioning deformed hole 252b of the side pressure spring 250.

側圧バネ250を組込む際には、側圧バネ250の側圧部254が作動車240の歯車部241に軽く当接して組まれても、離間して組まれても、作動車240の歯車部241に側圧バネ250の側圧が十分に掛からなければ、組み込み作業性の差異は無い。 When the side pressure spring 250 is assembled, the side pressure portion 254 of the side pressure spring 250 is assembled lightly against the gear portion 241 of the operating vehicle 240 or assembled separately from the gear portion 241 of the operating vehicle 240. If the side pressure of the side pressure spring 250 is not sufficiently applied, there is no difference in assembling workability.

また、側圧バネ250が躍制バネの場合でも同様の効果を得ることが可能となる。
図16a、図16bの状態から、側圧バネ250を押さえる側圧バネ押さえ260を組むことで、図15の作動車240は、側圧バネ250の側圧部254で側圧された状態となるが、この際に、側圧バネ250の反力を基台230の規制突起部233a〜233dで受けるので、側圧バネ250の位置がずれることを防止している。これにより、側圧バネ250の側圧部254は、作動車240に弾力的に作用する。
Further, even when the side pressure spring 250 is a leap spring, the same effect can be obtained.
16A and 16B is assembled with the side pressure spring press 260 that presses the side pressure spring 250, the operation vehicle 240 of FIG. 15 is in a state of being laterally pressed by the side pressure portion 254 of the side pressure spring 250. Since the reaction force of the side pressure spring 250 is received by the restricting projections 233a to 233d of the base 230, the position of the side pressure spring 250 is prevented from shifting. As a result, the side pressure portion 254 of the side pressure spring 250 acts elastically on the operating wheel 240.

〔実施例4〕
次に本発明の実施例4を説明する。
図17aは本発明の実施例4である充電式時計の平面図、図17bは図17aの要部平面図、図17cは図17bの要部断面図である。
Example 4
Next, a fourth embodiment of the present invention will be described.
17a is a plan view of a rechargeable timepiece that is Embodiment 4 of the present invention, FIG. 17b is a plan view of relevant parts of FIG. 17a, and FIG. 17c is a sectional view of relevant parts of FIG. 17b.

図において、340は充電式時計の蓄電部である二次電池ブロック、341は二次電池ブロックの蓄電部である二次電池、342は二次電池の負極側に固定された二次電池リード板である。320は回路基板、350は回路基板320と二次電池ブロック340とを導通するための接点バネである。 In the figure, 340 is a secondary battery block which is a power storage unit of a rechargeable watch, 341 is a secondary battery which is a power storage unit of the secondary battery block, and 342 is a secondary battery lead plate fixed to the negative electrode side of the secondary battery. It is. 320 is a circuit board, and 350 is a contact spring for conducting the circuit board 320 and the secondary battery block 340.

充電式時計では、一般の時計利用者が誤って二次電池を一次電池に交換しても、一次電池が充電されないようにするため、二次電池の負極側に電極になる二次電池リード板342を固定して二次電池341をブロック化している。二次電池リード板342は、二次電池341の側面側に突出するように配置され、そして回路基板320側から導出されてくる接続バネ350を二次電池リード板342の端部に圧接させて導通を取っている。 In a rechargeable watch, a secondary battery lead plate that serves as an electrode on the negative electrode side of the secondary battery in order to prevent the primary battery from being charged even if a general watch user mistakenly replaces the secondary battery with the primary battery. 342 is fixed and the secondary battery 341 is blocked. The secondary battery lead plate 342 is disposed so as to protrude from the side surface of the secondary battery 341, and the connection spring 350 led out from the circuit board 320 side is pressed against the end of the secondary battery lead plate 342. Taking continuity.

通常、一次電池には二次電池リード板342に相当するものが付いていないので、こうす
ることにより、充電式時計に一次電池を組み込んでも、回路基板320と導通する接点バネ350と一次電池を接触させることができないようになっている。
ところが、時計の利用者によっては、わざわざ一次電池に二次電池リード板342に相当する部材を取り付けて利用しようとする場合もあるため、二次電池そのものを取り出せない構造にすることが望まれていた。しかし、時計に二次電池を先に組み込んで取り外しできない状態にしてから回路基板320側の接点バネを組み込むのは組み込みしにくいという問題があった。
Normally, the primary battery does not have an equivalent to the secondary battery lead plate 342. Therefore, even if the primary battery is incorporated in the rechargeable watch, the contact spring 350 and the primary battery that are electrically connected to the circuit board 320 can be connected. It cannot be touched.
However, some users of the watch may bother to attach and use a member corresponding to the secondary battery lead plate 342 to the primary battery, and thus it is desired to have a structure in which the secondary battery itself cannot be taken out. It was. However, there is a problem that it is difficult to incorporate the contact spring on the circuit board 320 side after the secondary battery is assembled in the watch in a state where it cannot be removed.

そこで実施例4では充電式時計に本発明を適用して問題を解決した例を示す。実施例4では二次電池ブロック340を上面側から電池保持板360で固定している。電池保持板360は二次電池341の上面を半分以上を覆っているので、二次電池341だけを一般の利用者が取り出すのは難しい構造になっている。プラスチック製の基台330には接点バネ350を搭載するための搭載面331があり、搭載面331には接点バネ350を位置決めするための位置決め突起部332が設けられている。 Therefore, in the fourth embodiment, an example in which the present invention is applied to a rechargeable timepiece to solve the problem will be described. In Example 4, the secondary battery block 340 is fixed by the battery holding plate 360 from the upper surface side. Since the battery holding plate 360 covers more than half of the upper surface of the secondary battery 341, it is difficult for a general user to take out only the secondary battery 341. The plastic base 330 has a mounting surface 331 for mounting the contact spring 350, and the mounting surface 331 is provided with a positioning protrusion 332 for positioning the contact spring 350.

接点バネ350は基台330の搭載面331に搭載される基部351と、位置決め突起部332に係合するために基部351に設けた位置決め穴352を有し、基台330の搭載面331から基台330の側面に沿って折り曲げられた弾性部353を有し、その弾性部353の先端には、二次電池リード板342に接触するための接点部354を有している。 The contact spring 350 has a base 351 mounted on the mounting surface 331 of the base 330 and a positioning hole 352 provided in the base 351 for engaging with the positioning protrusion 332. The elastic portion 353 is bent along the side surface of the base 330, and a contact portion 354 for contacting the secondary battery lead plate 342 is provided at the tip of the elastic portion 353.

接点バネ350の基部351に設けた位置決め穴352の径は、位置決め突起部332の径よりも大きくなっているので、前述の実施例と同様に、接点バネ350の基部351を基台330の搭載面331や位置決め突起部332の突出方向に対して正対させずに斜めに組み込むことにより、接点バネ350の接点部354を二次電池リード板342に対して軽く接触するか、または離間した状態で組み込むことが可能である。 Since the diameter of the positioning hole 352 provided in the base 351 of the contact spring 350 is larger than the diameter of the positioning projection 332, the base 351 of the contact spring 350 is mounted on the base 330 in the same manner as in the above-described embodiment. A state in which the contact portion 354 of the contact spring 350 is lightly contacted or separated from the secondary battery lead plate 342 by being incorporated obliquely without facing the projection direction of the surface 331 or the positioning projection 332 Can be incorporated.

その後で回路基板320を組み込むことにより、接点バネ350の基部351は基台330の搭載面331に正対して固定され、同時に接点部354が二次電池リード板342の端部に所定の接点圧を持って弾力的に接触する。 After that, by incorporating the circuit board 320, the base portion 351 of the contact spring 350 is fixed to face the mounting surface 331 of the base 330, and at the same time, the contact portion 354 is applied to the end of the secondary battery lead plate 342 with a predetermined contact pressure. Hold it elastically.

各実施例に示したように本発明によれば、部品の組み込みが容易になり、生産性を向上させることができた。
なお、各実施例で説明した作用部品は、他部品に作用する作用部が、基部から折り曲げて形成されているもので説明したが、本発明はその構造に限定されるものではない。例えば、実施例1の場合は、他部品である太陽電池の電極部の位置と、作用部品である接点バネの接点部とを同じ高さに設定すれば、接点バネは平板形状で形成することができるものである。実施例3の場合も、他部品である作動車の歯車部の位置と、作用部品である側圧バネの側圧部とを同じ高さに設定すれば、側圧バネは平板形状で形成することができるものである。
As shown in each of the embodiments, according to the present invention, it is easy to incorporate components, and productivity can be improved.
In addition, although the action part demonstrated in each Example demonstrated that the action part which acts on other parts was formed by bending from a base part, this invention is not limited to the structure. For example, in the case of Example 1, if the position of the electrode part of the solar cell that is another part and the contact part of the contact spring that is the working part are set to the same height, the contact spring is formed in a flat plate shape. Is something that can be done. In the case of the third embodiment as well, the side pressure spring can be formed in a flat plate shape by setting the position of the gear portion of the working vehicle, which is another component, and the side pressure portion of the side pressure spring, which is the working component, to the same height. Is.
