ために、ＩＣは回路基板上におけるパネル側に配置され
ていた。In conventional electronic watches in which a panel and a circuit board are in direct electrical contact, an IC is placed on the panel side of the circuit board for electrical connection between the panel and the circuit board.
このようなＩＣの配置構造は、時計体を厚くする大きな
要因となっていた。This arrangement of ICs has been a major factor in making the watch body thicker.
それ故時計体を薄くするために、ＩＣを回路基板上にお
けるパネルと反対側に配置すると、今度はパネルと回路
基板とを直接的に電気的接続σせるために、回路基板に
スルーホールなどを設けて出力端子をパネル側にもって
こなければならなくなり、出力端子の数に等しい数のス
ルーホールが必要となってくるので、コスト高な回路基
板となり、時計の多機能化も困難となる欠点を有してい
た。Therefore, in order to make the watch body thinner, the IC is placed on the opposite side of the circuit board from the panel, and in order to make a direct electrical connection between the panel and the circuit board, through holes etc. are installed on the circuit board. Since the number of through holes equal to the number of output terminals is required, the circuit board becomes expensive and it is difficult to make the watch multifunctional. It had
本考案は上記の欠点を除去し、時計体の薄型化をはかる
ことを目的とする。The present invention aims to eliminate the above-mentioned drawbacks and to reduce the thickness of the watch body.
以下締付図面の実施例に基き本考案を詳細に説明する。The present invention will be described in detail below based on examples of tightening drawings.
第１図は従来の電子時計の断面図である。地板１の上に
パネル２が置かれ、地板１にあるピンｌａｈよび１ｂに
ガイドされて、パネル枠３が組み込１れる。FIG. 1 is a sectional view of a conventional electronic timepiece. A panel 2 is placed on the base plate 1, and a panel frame 3 is assembled by being guided by pins lah and 1b on the base plate 1.
パネル枠３には、内部にＩＣ４ａなどの素子を有する回
路基板４が、熱圧着あるいは接着などの手段によう固着
されている。A circuit board 4 having elements such as an IC 4a inside is fixed to the panel frame 3 by means such as thermocompression bonding or adhesive bonding.
しかもパネル２との接触部４ｂは、パネル枠３とは固着
されて訃らず、組み込んだときパネル３の基板押し付は
部３ａにより適当な圧縮力で弾性的にパネル２の電極部
２ａに押し付けられている。Moreover, the contact part 4b with the panel 2 is fixed to the panel frame 3 and does not bend, and when assembled, the board of the panel 3 is pressed elastically onto the electrode part 2a of the panel 2 with an appropriate compressive force by the part 3a. Being forced.
パネル枠３の上に時計構造をしつか９させるために用い
られた押え板５が乗り、ネジ６ａおよび６ｂがすべての
部品をネジ締め固定している。A holding plate 5 used to hold the clock structure in place rests on the panel frame 3, and screws 6a and 6b fasten and fix all the parts.
第２図は本考案の電子時計の断面図である。FIG. 2 is a sectional view of the electronic timepiece of the present invention.
ＩＣ１４ａは回路基板１４上でパネル１２とは反対側に
あり、パネル枠１３のＩＣ逃げ部１３ａに配置されてい
る。The IC 14a is located on the opposite side of the panel 12 on the circuit board 14, and is arranged in the IC relief portion 13a of the panel frame 13.
回路基板１４のパネル１２との接触部１４ｂの斜視図を
第３図に示す。A perspective view of the contact portion 14b of the circuit board 14 with the panel 12 is shown in FIG.
接触部１４ｂにはパネル１２と接続のための大穴１４ｃ
があり、その大穴１４ｃｌ’ｉ：電極パターン１４ｄ〜
１４ｔが橋わたしされて釦シ、その電極パターン１４ｄ
〜１４１はパネル枠１３の基板押し付は部１３ａにより
押し付けられ、第４図に示すように、パネル１２へ接触
する。The contact portion 14b has a large hole 14c for connection with the panel 12.
There is a large hole 14cl'i: electrode pattern 14d~
14t is bridged over the button, its electrode pattern 14d
141 is pressed by the substrate pressing portion 13a of the panel frame 13 and comes into contact with the panel 12 as shown in FIG.
以上のように本考案によれば、スルーホールなどの手段
によらなくても回路基板とパネルとの電気的接続が可能
となり、コストの安い回路基板を提供できるばかりでな
く、電極パターンの高密度配線が可能な構造のために多
機能化をはかる上でその効果は絶大である。As described above, according to the present invention, it is possible to electrically connect the circuit board and the panel without using means such as through holes, and it is possible not only to provide a low-cost circuit board but also to provide a high-density electrode pattern. This is extremely effective in achieving multifunctionality due to the structure that allows wiring.
