前記構成の一体型ヒューズ１においては、入出力端子部３、４やその間に設けられる溶断部５が一つのバスバー２により一体的に形成されているので、いずれか１つの溶断部が溶断した場合には一体型ヒューズ１全体を取り替える必要がある。しかし、一体型ヒューズ全体を取り替えることとなると、コストが高くなるだけでなく、入出力端子部の接続をすべてやり直す必要があり、そのための時間や労力もかかるという問題がある。
また、自動車のバッテリ等に装備された一体型ヒューズにおいて、出先でヒューズが溶断して走行不能となった場合、一時的でも走行できるように緊急的な処置をしなければならない場合があるが、前記のような一体型ヒューズであると、一体型ヒューズ全部を取り替えない限り走行は困難であり、前記のような処置もとれないという問題がある。 In the integrated fuse 1 having the above-described configuration, since the input / output terminal portions 3 and 4 and the fusing portion 5 provided therebetween are integrally formed by one bus bar 2, any one fusing portion is blown. It is necessary to replace the entire integrated fuse 1. However, if the whole integrated fuse is replaced, not only will the cost be increased, but it will be necessary to reconnect all of the input / output terminal portions, which will also take time and effort.
In addition, in an integrated fuse equipped in a battery of an automobile, etc., if the fuse blows off at the destination and it becomes impossible to run, it may be necessary to take emergency measures so that it can run even temporarily, In the case of the integrated fuse as described above, it is difficult to travel unless all the integrated fuses are replaced, and there is a problem that the above-described measures cannot be taken.

本発明は前記問題に鑑みてなされたものであり、一体型ヒューズ内の一部の溶断部が溶断された場合に、一体型ヒューズ全体を取り替えなくても、溶断された出力端子部に接続していた電線に繋がれている機器を再び作動させることができると共に、ヒューズとしての機能も容易に復活させることが可能な一体型ヒューズを提供することを課題としている。   The present invention has been made in view of the above problems, and when a part of the fused part in the integrated fuse is blown, it is connected to the blown output terminal part without replacing the entire integrated fuse. It is an object of the present invention to provide an integrated fuse that can re-activate the equipment connected to the wire that has been used and can easily restore the function as a fuse.

前記課題を解決するために、本発明は、１つの入力端子部と、該入力端子部に連続させた共通回路部と、該共通回路部から分岐させた複数の細幅部とした溶断部と、各溶断部に連続させた複数の出力端子部とを導電性金属板で一体的に設けた一体型ヒューズであって、
前記共通回路部から分岐させたスペア用接続端子部を前記複数の溶断部と並列に設け、前記各出力端子部には電線端末の端子とのボルト締結用のボルト穴を設けると共に、前記スペア用接続端子部にもボルト締結用のボルト穴を設け、
前記溶断部が溶断された出力端子部と接続されていた電線端末の端子を両端にボルト穴を設けたスペア用端子板の一端側にボルトで締結固定すると共に、該スペア用端子板の他端側を前記スペア用接続端子部とボルトで締結固定できる構成としていることを特徴とする一体型ヒューズを提供している。 In order to solve the above problems, the present invention provides one input terminal portion, a common circuit portion continuous to the input terminal portion, and a fusing portion as a plurality of narrow portions branched from the common circuit portion. An integrated fuse in which a plurality of output terminal portions connected to each fusing portion are integrally provided with a conductive metal plate,

また、前記構成によれば、両端にボルト穴を設けたスペア用端子板を用いて、その一端側を前記スペア用接続端子部とボルト締結し、溶断された出力端子部から取り外した電線端末の端子を、スペア用端子板の他端側に横方向に少し移動させてボルト締結できるので、前記電線端末の端子と前記スペア用接続端子部との接続を容易に行うことができる。
即ち、両端にボルト穴を設けたスペア用端子板を電線端末の端子とスペア用接続端子部との間に介在させ、それぞれをボルトで締結固定できるような構成にすることで、電線端末の端子とスペア用接続端子部との接続を無理なく簡単に行なうことができ、また、前記スペア用端子板の付け替えも容易に行うことができる。 According to the said structure, in order to fasten and fix the terminal of an electric wire terminal and each output terminal part with a volt | bolt, when a fusing part is blown out, it is connected to the blown out output terminal part only by releasing a volt | bolt. Only the terminal of the wire end that has been removed can be easily removed from the output terminal portion.
Moreover, according to the said structure, using the spare terminal board which provided the bolt hole at both ends, the one end side is bolt-fastened with the said connection terminal part for spares, and the electric wire terminal removed from the fused output terminal part Since the terminal can be slightly fastened in the lateral direction to the other end side of the spare terminal plate and bolted, the connection between the terminal of the wire terminal and the spare connection terminal portion can be easily performed.
That is, a terminal plate for a wire terminal is provided by interposing a spare terminal plate having bolt holes at both ends between the terminal of the wire terminal and the connecting terminal portion for spare, and fastening them with bolts. Can be easily and reasonably connected to each other and the spare terminal plate can be easily replaced.

電線端末の端子とスペア用接続端子部との間に介在させる前記スペア用端子板として、両端にボルト穴を設けた板ヒューズを用いている。特に、溶断された溶断部と同じ通電容量の板ヒューズを用い、該板ヒューズの一端側をスペア用接続端子部とボルトで締結固定すると共に、溶断された出力端子部と接続されていた電線端末の端子を前記板ヒューズの他端側に繋ぎかえてボルトで締結固定するだけで、一体型ヒューズ全体を取り替えることなく、ヒューズとしての機能を完全に復活させることができる。 And with the spare terminal plate to be interposed between the terminals and the spare connection terminal portion of the wire end, and a plate fuse provided with bolt holes at both ends. In particular, using a plate fuse having the same current-carrying capacity as the blown fused portion, one end of the plate fuse is fastened and fixed with a spare connection terminal portion and a bolt, and the wire terminal connected to the blown output terminal portion By simply connecting the terminal to the other end of the plate fuse and fastening and fixing it with a bolt, the function as a fuse can be completely restored without replacing the whole integrated fuse.

また、溶断時において、溶断された溶断部と同じ通電容量の板ヒューズが手元にない場合には、異なる通電容量の板ヒューズを応急的に取り付けておき、その後、溶断された溶断部と同じ通電容量の板ヒューズに付け替えることが好ましい。
さらに、溶断部が溶断されることにより自動車が途中で走行不能になった場合などに、板ヒューズが手元にない場合は、緊急処置として、両端にボルト穴を設けた端子板を一時的に取り付けてとりあえず走行可能な状態とし、その後ディーラーなどで溶断された溶断部と同じ通電容量の板ヒューズに付け替えることも可能である。
なお、スペアの板ヒューズをヒューズボックス等に取り付けておいてもよい。 Also, if a sheet fuse with the same current carrying capacity as the blown melted part is not at hand at the time of fusing, a board fuse with a different current carrying capacity must be installed immediately, and then the same current flow as the blown fused part. It is preferable to replace the plate fuse with a capacity.

また、出力端子部に接続される電線端末の端子は、ボルト穴を有するＬＡ端子や圧着端子等が好ましい。
さらに、電線端末に接続される側の板ヒューズの端部をタブ状とすれば、電線端末のコネクタを接続することもできる。 The spare connection terminal portion is formed by branching the bus bar from the common circuit portion as in the case of the other plurality of narrow fusing portions, but at least one spare connection terminal portion for every ten fusing portions. It is preferable to provide one spare connection terminal portion for every 4 to 6 fusing portions.

The bus bar is fastened and fixed with bolts B, and the other end side (22b side) of the plate fuse 22 is used as an output section.

なお、前記スペア用接続端子部２３の溶断部として取り付ける板ヒューズ２２の通電容量は、一体型ヒューズの複数の溶断部１４の最大通電容量と等しくしていることが好ましい。
したがって、一体型ヒューズのいずれかの溶断部１４が溶断された場合には、スペア用接続端子部２３の溶断部として予め取り付けられている最大通電容量の板ヒューズ２２の他端側（出力部）に、応急処置として溶断された出力端子に接続されていた電線端末の端子をボルトで締結固定し、その後、前記板ヒューズ２２の通電容量が溶断された溶断部１４の通電容量よりも大きい場合には、溶断された溶断部１４の通電容量と等しい通電容量の板ヒューズに付け替えればよい。 The energizing capacity of the plate fuse 22 to be attached as the fusing part of the spare connection terminal part 23 is preferably equal to the maximum energizing capacity of the plurality of fusing parts 14 of the integrated fuse.
Therefore, when one of the fusing portions 14 of the integrated fuse is blown, the other end side (output portion) of the plate fuse 22 having the maximum current carrying capacity that is attached in advance as the fusing portion of the spare connection terminal portion 23. In addition, when the terminal of the electric wire terminal connected to the fused output terminal is fastened with bolts as an emergency measure, and then the energization capacity of the plate fuse 22 is larger than the energization capacity of the melted portion 14 that has been fused. May be replaced with a plate fuse having a current-carrying capacity equal to the current-carrying capacity of the fused part 14 that has been blown.

前記構成によれば、共通回路部１３から分岐させた１組の板ヒューズ（溶断部）２２とその端部の出力部とからなるスペア用接続端子部２３を予め設けておくことにより、いずれかの溶断部１４が溶断された場合に、溶断された出力端子部１６と接続されていた電線端末のＬＡ端子２０をスペア用接続端子部２３の出力部に繋ぎかえるだけで、ヒューズとしての機能を復活させることができ、繋ぎかえも非常に容易に行うことができる。   According to the above-described configuration, either one of the pair of plate fuses (fused portions) 22 branched from the common circuit portion 13 and the spare connection terminal portion 23 including the output portion at the end thereof is provided in advance. When the fusing part 14 is blown, the LA terminal 20 of the electric wire terminal connected to the blown output terminal part 16 is simply connected to the output part of the spare connection terminal part 23, thereby functioning as a fuse. It can be revived and reconnection is very easy.
