Description

【０００１】
【発明の属する技術分野】
本発明は、基板への実装に好適なヒューズ保持具に関するものである。
【０００２】
【従来の技術】
従来のこの種のヒューズ保持具は、図９に示すように、ヒューズ（図示せず）を保持する保持部１と、この保持部１から延設され、かつ基板２に穿設された差し込み孔３にインサートマシンを介して挿入されるリード部４を有し、前記リード部４の先端を図１０，図１１に示すようにテーピング台紙５と接着テープ６とにより挟んで固定し前記インサートマシンの送り機構に適合するピッチで送り孔７を前記テーピング台紙５に形成して搬送するようにしていた。そして前記リード部４は図９に示すように、保持部１との付け根部に位置し、かつ基板２への実装状態で差し込み孔３の内部に配置され基板回路と電気的に接続される差し込み付け根部４ａと、前記インサートマシンのガイドピンと接触する側のリード相当部４ｂとに区画し、前記差し込み付け根部４ａに、板幅寸法を前記リード相当部４ｂより大きくした拡幅部を形成することにより、基板２への仮実装に際しては、リード相当部４ｂが基板２の差し込み孔３に差し込まれて該差し込み孔３の開口部に拡幅部が達すると、この拡幅部が差し込み孔３に適合し、両者の間の隙間がわずかとなり、これにより、リード相当部４ｂ単独での基板２の差し込み孔３に対するがたつきがなくなって、一対のリード部４を持つヒューズ保持具を基板２に仮実装した際の固定状態が安定したものとなるようにしていた。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記従来のヒューズ保持具においては、差し込み付け根部４ａに、板幅寸法をリード相当部４ｂより大きくした拡幅部を形成しているため、リード相当部４ｂを基板２の差し込み孔３に差し込み、そしてこの差し込み孔３の開口部に拡幅部が適合した状態で、図１２に示すように、リード相当部４ｂを基板２の板面と水平方向に折り曲げた場合、この折り曲げ位置と、リード部４の幅広部と幅狭部の境界部分とが一致して、この境界部分に折り曲げ力が集中し、リード部４が折れやすいという課題を有していた。
【０００４】
本発明は上記従来の課題を解決するもので、リード部におけるリード相当部を基板の板面と水平方向に折り曲げた場合、リード部が折れにくいヒューズ保持具を提供することを目的とするものである。
【０００５】
【課題を解決するための手段】
上記目的を達成するために、本発明は以下の構成を有するものである。

【発明の実施の形態】
（実施の形態１）
以下、本発明の実施の形態１におけるヒューズ保持具について、図面を参照しながら説明する。
【００１５】
図１は本発明の実施の形態１におけるヒューズ保持具をテーピング台紙に貼着した状態を示す正面図、図２は同ヒューズ保持具の側面図、図３は同ヒューズ保持具の正面図、図４は同ヒューズ保持具の実装状態を示す縦断面図、図５は同ヒューズ保持具におけるリード部の折り曲げ状態を示す縦断面図である。
【００１６】
図１〜図５において、１１はヒューズ（図示せず）を保持する保持部で、この保持部１１は略Ｕ字形状に曲げられてヒューズ（図示せず）を保持する部分となるヒューズ保持部分１２を有している。また、このヒューズ保持部分１２の両側縁の中央部には導電路となる一対のリード部１３が一体に成形されている。そしてこの一対のリード部１３と前記保持部１１はりん青銅にスズめっきを施した板材を打ち抜くことにより構成しているものである。１４は前記ヒューズ保持部分１２の片側縁に突出形成されたＬ字形のストッパーで、このストッパー１４はヒューズ保持部分１２に保持されたヒューズ（図示せず）の端部の抜け止め作用をなすものである。
【００１７】
前記保持部１１と一対のリード部１３よりなるヒューズ保持具は、図１，図２に示すように、一対のリード部１３の先端をテーピング台紙１５と接着テープ１６とにより挟んで固定し、かつテーピング台紙１５にはインサートマシンの送り機構に適合するピッチで送り孔１７を形成し、インサートマシン内での搬送が可能となるようにしている。
【００１８】
また前記一対のリード部１３は、図４に示すように、基板１８に穿設された一対の差し込み孔１９にインサートマシンを介して挿入されるもので、この一対のリード部１３の形状は、図１，図３，図４に示すような形状となっているものである。すなわち、この一対のリード部１３は、それぞれ前記ヒューズ（図示せず）を保持する保持部１１との付け根部に位置し、かつ基板１８への実装状態で差し込み孔１９の内側に配置され基板１８の回路と電気的に接続される差し込み付け根部２０と、前記インサートマシンのガイドピンと接触する側のリード相当部２１とに区画している。そして前記一対のリード部１３における差し込み付け根部２０は、基板１８に穿設した一対の差し込み孔１９の相対向する内側の壁面に押し付けられる当接部２２と、この当接部２２から前記リード相当部２１につながる傾斜部２３とにより構成しているものである。
【００１９】
上記のように構成されたヒューズ保持具をインサートマシンにより実装する場合は、まず、ヒューズ保持具における一対のリード部１３を基板１８に穿設した一対の差し込み孔１９に挿入する。この挿入は実装用に設けられたインサートマシンのガイドピンが用いられ、基板１８の裏面側から貫通されたガイドピンとリード部１３とを接触させて下降移動させることにより、図４に示すように、一対のリード部１３における差し込み付け根部２０が基板１８に穿設した一対の差し込み孔１９に挿入される。そしてこの挿入状態においては、一対のリード部１３の差し込み付け根部２０における当接部２２が一対の差し込み孔１９の相対向する内側の壁面に押し付けられることになり、これにより、がたつきもなくなるため、一対のリード部１３を持つヒューズ保持具を基板１８に仮実装した際の固定状態も安定したものが得られるものである。そして、前記一対のリード部１３における差し込み付け根部２０を基板１８に穿設した一対の差し込み孔１９に挿入した後、図５に示すように、一対のリード部１３におけるリード相当部２１を基板１８の板面と水平方向に折り曲げることにより、仮実装を完了するものである。この場合、一対のリード部１３における差し込み付け根部２０の板幅寸法と、リード相当部２１の板幅寸法が略同じであるため、一対のリード部１３におけるリード相当部２１を基板１８の板面と水平方向に折り曲げた場合においても、折り曲げ力が一箇所に集中するということはなくなり、これにより、リード部１３の折り曲げに対する折れも防止することができるものである。
【００２０】
また前記ヒューズ（図示せず）を保持する保持部１１と、基板１８に穿設された一対の差し込み孔１９にインサートマシンを介して挿入される一対のリード部１３は同一材料、すなわち、りん青銅にスズめっきを施した板材で構成しているため、ヒューズ（図示せず）を保持する保持部１１と一対のリード部１３を一体に成形することができ、これにより、コストダウンが図れるものである。
【００２１】
（実施の形態２）
以下、本発明の実施の形態２におけるヒューズ保持具について、図面を参照しながら説明する。
【００２２】
図６は本発明の実施の形態２におけるヒューズ保持具の正面図、図７は同ヒューズ保持具の実装状態を示す縦断面図、図８は同ヒューズ保持具におけるリード部の折り曲げ状態を示す縦断面図である。
【００２３】
本発明の実施の形態２におけるヒューズ保持具は、上記本発明の実施の形態１におけるヒューズ保持具と実質的に同一の構成を有するもので、上記本発明の実施の形態１と異なる点のみを説明する。すなわち、本発明の実施の形態２における一対のリード部１３は、それぞれヒューズ（図示せず）を保持する保持部１１との付け根部に位置し、かつ基板１８への実装状態で差し込み孔１９の内側に配置され基板１８の回路と電気的に接続される差し込み付け根部２０と、インサートマシンのガイドピンと接触する側のリード相当部２１とに区画し、そして前記一対のリード部１３における差し込み付け根部２０は、基板１８に穿設した一対の差し込み孔１９の相反する外側の壁面に押し付けられる当接部２２ａと、この当接部２２ａから前記リード相当部２１につながる傾斜部２３ａとにより構成しているものである。
【００２４】
上記のように構成されたヒューズ保持具をインサートマシンにより実装する場合は、まず、ヒューズ保持具における一対のリード部１３を基板１８に穿設した一対の差し込み孔１９に挿入する。この挿入は実装用に設けられたインサートマシンのガイドピンが用いられ、基板１８の裏面側から貫通されたガイドピンとリード部１３とを接触させて下降移動させることにより、図７に示すように、一対のリード部１３における差し込み付け根部２０が基板１８に穿設した一対の差し込み孔１９に挿入される。そしてこの挿入状態においては、一対のリード部１３の差し込み付け根部２０における当接部２２ａが一対の差し込み孔１９の相反する外側の壁面に押し付けられることになり、これにより、がたつきもなくなるため、一対のリード部１３を持つヒューズ保持具を基板１８に仮実装した際の固定状態も安定したものが得られるものである。そして、前記一対のリード部１３における差し込み付け根部２０を基板１８に穿設した一対の差し込み孔１９に挿入した後、図８に示すように、一対のリード部１３におけるリード相当部２１を基板１８の板面と水平方向に折り曲げることにより、仮実装を完了するものである。この場合、一対のリード部１３における差し込み付け根部２０の板幅寸法と、リード相当部２１の板幅寸法が略同じであるため、一対のリード部１３におけるリード相当部２１を基板１８の板面と水平方向に折り曲げた場合においても、折り曲げ力が一箇所に集中するということはなくなり、これにより、リード部１３の折り曲げに対する折れも防止することができるものである。
【００２５】
また前記ヒューズ（図示せず）を保持する保持部１１と、基板１８に穿設された一対の差し込み孔１９にインサートマシンを介して挿入される一対のリード部１３は同一材料、すなわち、りん青銅にスズめっきを施した板材で構成しているため、ヒューズ（図示せず）を保持する保持部１１と一対のリード部１３を一体成形することができ、これにより、コストダウンが図れるものである。
【００２６】
なお、上記本発明の実施の形態１，２においては、ヒューズ（図示せず）を保持する保持部１１と、基板１８に穿設された一対の差し込み孔１９にインサートマシンを介して挿入される一対のリード部１３を同一材料、すなわち、りん青銅にスズめっきを施した板材で構成したものについて説明したが、ヒューズ（図示せず）を保持する保持部１１と一対のリード部１３を別個に構成し、両者１１，１３を溶接や接合等により接続してもよいもので、この場合は、保持部１１とリード部１３をそれぞれ所望の形状にコスト的にも安価にして容易に形成することができるという効果を有するものである。
【００２７】
また上記本発明の実施の形態１，２においては、ヒューズ（図示せず）を保持する保持部１１と、基板１８に穿設された一対の差し込み孔１９にインサートマシンを介して挿入される一対のリード部１３とを有し、前記一対のリード部１３の先端をテーピング台紙１５と接着テープ１６とにより挟んで固定し前記インサートマシンの送り機構に適合するピッチで送り孔１７を前記テーピング台紙１５に形成して搬送するようにしたヒューズ保持具について説明したが、ヒューズを保持する保持部と、基板に穿設された一対の差し込み孔に挿入される一対のリード部とを有するヒューズ保持具において、上記した本発明の実施の形態１，２と同様に、前記一対のリード部を、それぞれ前記保持部との付け根部に位置し、かつ基板への差し込み状態で差し込み孔の内部に配置される差し込み付け根部と、リード相当部とに区画し、前記一対のリード部の差し込み付け根部を、基板に穿設された一対の差し込み孔の相対向する内側の壁面に押し付けられる当接部、あるいは基板に穿設された一対の差し込み孔の相反する外側の壁面に押し付けられる当接部と、この当接部から前記リード相当部につながる傾斜部とにより構成し、そしてこのような一対のリード部を持つヒューズ保持具の一対のリード部を基板に穿設された一対の差し込み孔に手動又は治工具で差し込んでヒューズ保持具を保持するようにしてもよいもので、この場合においても、一対のリード部の差し込み付け根部を上記したような構成としているため、ヒューズ保持具の一対のリード部を基板に穿設された一対の差し込み孔に手動又は治工具で差し込んだ際の保持状態も安定したものが得られるものである。
【００２８】
【発明の効果】
以上のように本発明のヒューズ保持具は、一対のリード部を、それぞれ前記保持部との付け根部に位置し、かつ基板への実装状態で差し込み孔の内部に配置され基板の回路と電気的に接続される差し込み付け根部と、前記インサートマシンのガイドピンと接触する側のリード相当部とに区画し、前記一対のリード部の差し込み付け根部を、基板に穿設された一対の差し込み孔の相対向する内側の壁面に押し付けられる当接部と、この当接部から前記リード相当部につながる１つの傾斜部とにより構成し、前記一対のリード部を前記基板の下面において前記基板の板面と水平方向に折り曲げるとともに、前記一対のリード部の差し込み付け根部の板幅とリード相当部の板幅を略同じにし、かつ前記１つの傾斜部を前記差し込み孔の内部から前記基板の下方にかけて連続するように位置させているため、基板の差し込み孔への挿入後は、一対のリード部の差し込み付け根部における当接部が一対の差し込み孔の相対向する内側の壁面に押し付けられることになり、これにより、がたつきもなくなるため、一対のリード部を持つヒューズ保持具を基板に仮実装した際の固定状態も安定したものが得られ、しかも一対のリード部における差し込み付け根部の板幅寸法と、リード相当部の板幅寸法が略同じであるため、一対のリード部におけるリード相当部を基板の板面と水平方向に折り曲げた場合においても、折り曲げ力が一箇所に集中するということはなくなり、これにより、リード部の折り曲げに対する折れも防止できるという効果を有するものである。

The feed holes 7 are formed in the taping mount 5 at a pitch suitable for the feed mechanism and conveyed. As shown in FIG. 9, the lead part 4 is located at the base part of the holding part 1 and is inserted in the insertion hole 3 in a mounted state on the board 2 and is electrically connected to the board circuit. By dividing into a base portion 4a and a lead equivalent portion 4b on the side in contact with the guide pin of the insert machine, a widened portion having a plate width dimension larger than that of the lead equivalent portion 4b is formed on the insertion root portion 4a. In the temporary mounting on the substrate 2, when the lead equivalent portion 4b is inserted into the insertion hole 3 of the substrate 2 and the widened portion reaches the opening of the insertion hole 3, the widened portion fits into the insertion hole 3, The gap between the two becomes small, thereby eliminating rattling against the insertion hole 3 of the board 2 by the lead equivalent part 4b alone, so that the fuse holder having the pair of lead parts 4 is attached to the board 2. Fixed state at the time of implementation was as becomes stable.
[0003]
[Problems to be solved by the invention]
However, in the conventional fuse holder, since the widened portion having a plate width dimension larger than that of the lead equivalent portion 4b is formed in the insertion root portion 4a, the lead equivalent portion 4b is inserted into the insertion hole 3 of the substrate 2. When the lead equivalent portion 4b is bent in the horizontal direction with the plate surface of the substrate 2 in a state in which the widened portion is fitted to the opening of the insertion hole 3, as shown in FIG. 4 has a problem that the wide portion and the boundary portion of the narrow portion coincide with each other, the bending force concentrates on the boundary portion, and the lead portion 4 is easily broken.
[0004]
SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and it is an object of the present invention to provide a fuse holder in which a lead portion is not easily broken when a lead equivalent portion in a lead portion is bent in a horizontal direction with a plate surface of a substrate. is there.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention has the following configuration.
