Description

【考案の詳細な説明】［産業上の利用分野］この考案は、プリント基板用コネクタのよう
に、実装後にフラツクス洗浄を行うコネクタに関
するものである。[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a connector that undergoes flux cleaning after mounting, such as a printed circuit board connector.

［従来の技術］ (1) 第７図、第８図の例：カードエツヂコネクタの例で、１０はハウジン
グ、３０はコンタクトである。[Prior Art] (1) Examples shown in FIGS. 7 and 8: This is an example of a card edge connector, where 10 is a housing and 30 is a contact.

ハウジング１０には底部１２を有するコンタク
ト収容穴が設けられている。このコンタクト収容
穴にはコンタクト３０が収容されている。 The housing 10 is provided with a contact receiving hole having a bottom portion 12 . A contact 30 is housed in this contact housing hole.

またコンタクト３０の一端側は相手方コネクタ
のコンタクト（図示せず）と電気接触する接触部
であり、コンタクト収容穴の開口部側に位置して
おり、コンタクト３０の他端側はコンタクト収容
穴の底部１２の裏側（第８図の下側）に突き出て
プリント基板の配線パターンに接続されるテール
部となつている。 One end of the contact 30 is a contact portion that makes electrical contact with a contact (not shown) of a mating connector, and is located on the opening side of the contact housing hole, and the other end of the contact 30 is located at the bottom of the contact housing hole. 12 (bottom side in FIG. 8) and serves as a tail portion that is connected to the wiring pattern of the printed circuit board.

またコンタクト３０はコンタクト収容穴の底部
１２に固定されてる。 Further, the contact 30 is fixed to the bottom 12 of the contact receiving hole.

この場合は、ハウジング１０の底部１２に、複
数の孔１４を設ける。 In this case, a plurality of holes 14 are provided in the bottom 12 of the housing 10.

この孔１４を設ける理由は、コネクタ〜プリント基板間のフローソルダー
後の洗浄工程における、洗浄液の流れを良くし
て、洗浄効率を高め、洗浄工程終了後、洗浄液をすみやかにハウジ
ング１０内から排出する、ということである。 The reason for providing this hole 14 is to improve the flow of the cleaning liquid in the cleaning process after flow soldering between the connector and the printed circuit board, increasing cleaning efficiency, and to quickly discharge the cleaning liquid from the housing 10 after the cleaning process is completed. , That's what it means.

(2) 第９図の例：ところが一方、第９図のように、孔１４を設け
ないコネクタもある。(2) Example of FIG. 9: However, as shown in FIG. 9, there is also a connector that does not have the hole 14.

いつしよに搭載される素子の耐溶剤性の問題の
ために洗浄を行わないコネクタの場合である。 This is the case with connectors that are not cleaned due to problems with the solvent resistance of the components that are usually mounted.

フローソルダー時にフラツクスがハウジング１
０内に入り込まないようにするため、孔１４は設
けない。 During flow soldering, flux is applied to housing 1.
Hole 14 is not provided in order to prevent it from entering the hole.

(3) 製造上の問題について：上記のような、孔１４のあるものと、ないもの
２種類のコネクタを製造する場合、従来は、別々
のハウジング１０を製作していた。(3) Regarding manufacturing problems: When manufacturing two types of connectors, one with the hole 14 and the other without the hole 14 as described above, conventionally, separate housings 10 were manufactured.

［考案が解決しようとする問題点］上記のように、２種類のハウジング１０を作る
ために、 (1) ２種類の金型を製作・運用したり、 (2) １種類の金型で、中の部品を取換えながらハ
ウジング１０を製造したりする、という方法をとつていた。[Problems to be solved by the invention] As mentioned above, in order to make two types of housings 10, it is necessary to (1) manufacture and operate two types of molds, (2) use one type of mold, The method used was to manufacture the housing 10 by replacing the parts inside.

しかし、・２種類の金型を用意する(1)の場合は金型費が
大になり、・また、中の部品を取換える(2)の場合は、金型
の寿命が短くなる、などの問題があり、両方とも、コストアツプの要
因となつていた。 However, ・ In the case of (1), where two types of molds are prepared, the mold cost will be high. ・ Also, in the case of (2), where the parts inside are replaced, the life of the mold will be shortened, etc. There are two problems, both of which are factors that increase costs.

［問題点を解決するための手段］この考案は、上記問題を解決するため、１種類
の金型の製作・運用だけですむようにしたもの
で、第１ａ，１ｂ図のように、ハウジング１０の底部１２の所要箇所に、片面
または両面から凹部１６を設けて薄肉部分１８を
形成し、打抜き孔２０をあけやすくしたこと、を特徴とする。[Means for solving the problem] In order to solve the above problem, this invention is designed so that only one type of mold needs to be manufactured and operated, and as shown in FIGS. 1a and 1b, 12, recesses 16 are provided from one side or both sides to form thin-walled portions 18, making it easier to punch holes 20.

［実施例］第１ａ，１ｂ図のように、ハウジング１０は、
底部１２の、たとえば両面から凹部１６を設け
て、薄肉部分１８を形成した構造とする。[Example] As shown in FIGS. 1a and 1b, the housing 10 is
The bottom portion 12 has a structure in which a recessed portion 16 is provided from, for example, both sides, and a thin portion 18 is formed.

凹部１６を設ける場所、数は、従来の孔１４と
同様でよい。 The location and number of recesses 16 may be the same as those of the conventional holes 14.

凹部１６の形はこの場合、四角であるが（第１
ｂ図）、丸でもよい。 In this case, the shape of the recess 16 is square (first
(Figure b), it may be a circle.

また、凹部１６は底部１２の上下どちらかの片
側に設けるだけでもよい。 Moreover, the recessed portion 16 may be provided only on one side of the bottom portion 12, either the upper or lower side.

薄肉部分１８の厚みは、1.5mm以下が適当であ
る。 The thickness of the thin portion 18 is suitably 1.5 mm or less.

なお、本考案で、コンタクト３０は直接関係が
ないので、第１ａ，１ｂ図で図示を省略した。 In addition, since the contact 30 is not directly related to the present invention, its illustration is omitted in FIGS. 1a and 1b.

［作用］ (1) 洗浄液の孔を必要としないコネクタの場合：このハウジング１０を、そのまま使用する。[Effect] (1) For connectors that do not require cleaning fluid holes: This housing 10 is used as is.

底部１２には、凹部１６はあるが、孔はあいて
いないので、ハウジング１０内部にフラツクスは
侵入しない。 Although the bottom portion 12 has a recess 16, there is no hole, so that flux does not enter into the housing 10.

(2) 孔を必要とする場合：ハウジング１０の成形後、適当な時期におい
て、第２図、第３図のように、適当な治具で、薄
肉部分１８を打抜き、打抜き孔２０をあける。(2) When a hole is required: After the housing 10 is molded, at an appropriate time, as shown in FIGS. 2 and 3, the thin portion 18 is punched out using an appropriate jig to form a punched hole 20.

［他の実施態様］凹部１６の構造を次のようにしてもよい。[Other embodiments] The structure of the recess 16 may be as follows.

(1) 第４ａ図のように、凹部１６の底の周縁に、
たとえば断面が直角三角形の切込み２２を設け
る。(1) As shown in Figure 4a, on the periphery of the bottom of the recess 16,
For example, a notch 22 having a right triangular cross section is provided.

なお、切込み２２を設ける場所は、第４ｂ図
のように、凹部１６の周縁の全体でもよいし、
第４ｃ図のように、周縁の一部でもよい。 Note that the cut 22 may be provided at the entire periphery of the recess 16, as shown in FIG. 4b, or
It may also be a part of the periphery, as shown in FIG. 4c.

さらに、第４ｄ，４ｅ図のように、上または
下の凹部１６のどちらかだけとしてもよい。 Furthermore, as shown in FIGS. 4d and 4e, only either the upper or lower recess 16 may be provided.

このように切込み２２を設けると、上記のよ
うに薄肉部分１８の打抜き加工のとき、せん断
が生じ易く、孔が奇麗に抜ける。 When the notch 22 is provided in this manner, shearing is likely to occur during punching of the thin portion 18 as described above, and the hole will come out cleanly.

(2) 第５図のように、凹部１６は、側面１７が傾
斜するようにしてもよい。(2) As shown in FIG. 5, the side surfaces 17 of the recess 16 may be inclined.

このようにすると、成形後、ハウジング１０
を金型からとりだすのが容易になる。 In this way, after molding, the housing 10
It becomes easy to take out from the mold.

(3) 第６ａ，６ｂ図のように、丸（または角）の
溝状の凹部１６とし、リング状の薄肉部分１８
を形成するようにしてもよい。(3) As shown in Figures 6a and 6b, a round (or square) groove-shaped recess 16 and a ring-shaped thin part 18
may be formed.

［考案の効果］ハウジング１０の底部１２の所要箇所に、片面
または両面から凹部１６を設けて薄肉部分１８を
形成し、打抜き孔２０をあけやすくしたため、 (1) 孔１４を設けるか否かの選択は、ハウジング
１０を成形した後の適当な工程もしくは時期に
行うことができるので、１種類の金型を製作・
運用することで足りる。[Effects of the invention] Recesses 16 are provided on one or both sides of the bottom 12 of the housing 10 at required locations to form thin-walled portions 18, making it easier to punch out the holes 20. The selection can be made at an appropriate process or time after molding the housing 10, so one type of mold can be manufactured and
It is enough to operate it.

したがつて金型に要する費用が軽減される。 Therefore, the cost required for the mold is reduced.

(2) フラツクス洗浄用の孔を設けるか否かの選択
を後送りすることができるので、仕様変更など
に柔軟に対応できる利点をも有する。(2) Since the selection of whether or not to provide holes for flux cleaning can be postponed, it also has the advantage of being able to respond flexibly to changes in specifications.
