Description

【0001】
【発明の属する技術分野】
本発明は、端子螺合型のヒュージブルリンク等を収容する電気接続箱の端子取付け構造に関するものである。
【0002】
【従来の技術】
ヒュージブルリンクは、定格電流により形式が異なり、30〜50Aと低い電流特性でよいものには端子嵌合型のものが使用されるが、60〜100Aと高い電流特性が要求されるものには、図3に示すように電気接触部1にボルト孔3を穿設した螺合型ヒュージブルリンク5が使用される。
【0003】
この種の螺合型ヒュージブルリンク5を収容する電気接続箱には、例えば図4に示すものがある。この電気接続箱9は、本体11の上面にヒュージブルリンク収容部13を形成してあり、ヒュージブルリンク収容部13に収容した螺合型ヒュージブルリンク5の電気接触部1が露出する凹部15を側面に形成してある。また、電気接触部1と本体11との間には、ボルト孔3に中心が一致するナット17を配設してある。この電気接続箱9では、外部電源端子である丸形端子23を螺合型ヒュージブルリンク5のボルト孔3に一致させた後、ボルト25をナット17に螺合することで、丸形端子23を電気接触部1に取り付けていた。
【0004】
ところが、この電気接続箱9では、一方の電気接触部1は本体11の外側からボルト3を螺合できるが、他方の電気接触部1は本体11の内側からボルト25の螺合を行わなければならず、作業性の悪い問題があった。
このようなボルト挿通方向に起因する作業性の低下を解消するものとして、例えば図5に示す電気接続箱の端子取付け構造が提案された。この電気接続箱31は、本体33の直交する外壁33a、33bの隅部を切欠き、この外壁33a、33bの面に対して傾斜する隅部外壁35を形成し、更にこの隅部外壁35に直交する外壁を有する突設部37を設け、この突設部37に螺合型ヒュージブルリンク5のハウジング部39を設けてある。従って、この電気接続箱31によれば、一対の電気接触部1の両方共、本体33の外側からボルト25を螺合して、丸形端子23を電気接触部1に取り付けることができた。
【0005】
【発明が解決しようとする課題】
しかしながら、上述の電気接続箱31は、電気接触部1に螺合する両方のボルト25が本体11の外側から螺合可能となり、ボルト挿通方向に起因する作業性の低下は解消できるものの、丸形端子23を電気接触部1に取り付けるのに、本体33から引き上げた丸形端子23を一方の手で保持しながら、他方の手でボルト締めを行わなければならず、作業性の悪い問題があった。
本発明は上記状況に鑑みてなされたもので、螺合型ヒュージブルリンクの電気接触部に取り付ける端子を手で保持せずにボルト締めを行うことのできる電気接続箱の端子取付け構造を提供し、端子取付け作業性の向上を図ることを目的とする。
【0006】
【課題を解決するための手段】
上記目的を達成するための本発明に係る電気接続箱の端子取付け構造は、
『アンダーカバー、本体、および当該本体の上面に取り付けられるアッパーカバー、を有する電気接続箱の端子取付け構造であって、
前記本体の上面に形成された、前記本体の直交する外側壁の面に対して傾斜する溝部と、
前記溝部の中央に位置し、且つ前記本体の上面に配設されたヒュージブルリンク収容空間と、
前記溝部に立設され、前記本体の上面から突出し、且つ前記ヒュージブルリンク収容空間を囲む周壁と、
ボルトによりヒュージブルリンクの電気接触部と直角曲げ螺合端子の電気接触部とを接続するために設けられた、前記本体の直交する外側壁に形成され、且つ前記ヒュージブルリンク収容空間へ連通するボルト締め用開口部と、
前記アンダーカバーを前記本体に取り付けた時、前記ボルト締め用開口部を塞ぐために前記アンダーカバーに設けられた一対の塞ぎ壁と、
を備え、
前記ボルト締め用開口部に連通するとともに、前記周壁を越えて前記ヒュージブルリンク収容空間の内側へ拡がる端子挿入孔を前記周壁の外側の前記溝部の底面に穿設し、
前記端子挿入孔における前記周壁の下端にクランク状に屈曲した段部を形成し、
そして電線に接続された前記直角曲げ螺合端子の電気接触部を前記端子挿入孔に挿入したこと』を特徴とするものである。
【0007】
このように構成した電気接続箱の端子取付け構造では、直角曲げ螺合端子の接触部を端子挿入孔に挿入し、直角曲げ螺合端子全体をヒュージブルリンク収容空間側に押し込むと、直角曲げ螺合端子の接触部がヒュージブルリンクの電気接触部に当接し、同時に直角曲げ螺合端子の屈曲部が、周壁の段部に上方から当接され、直角曲げ螺合端子の上下方向の移動が規制される。これにより、直角曲げ螺合端子が手による保持なしでヒュージブルリンクの電気接触部に対して位置決めされる。
【0008】
【発明の実施の形態】
以下、本発明に係る電気接続箱の端子取付け構造の好適な実施の形態を図面を参照して詳細に説明する。
図1は本発明に係る電気接続箱の端子取付け構造を示す分解斜視図、図2は端子を挿入した状態の図1のA−A断面図である。
電気接続箱41の本体43の直交する外側壁45、47の隅部の上側にある該本体43の上面には、当該外側壁45、47の面に対して傾斜する溝部49が形成されている。溝部49の中央には、ヒュージブルリンク収容空間51が位置し、且つ本体43の上面に配設されている。このヒュージブルリンク収容空間51は、溝部49に立設され且つ本体43の上面から突出する周壁53によって囲まれている。
【0009】
ヒュージブルリンク収容空間51には端子螺合型の電気接触部55を有したヒュージブルリンク57が装着可能となっており、ヒュージブルリンク収容空間51に装着されたヒュージブルリンク57は平行な一対の電気接触部55が本体43の内部に垂下して配置されるようになっている。
【0010】
直交する一対の外側壁45、47にはヒュージブルリンク収容空間51へ連通するボルト締め用開口部59をそれぞれ穿設してあり、ボルト締め用開口部59はヒュージブルリンク収容空間51に挿入したヒュージブルリンク57の電気接触部55を外部へ露出する。本体43の下部には、アンダーカバー61が取り付けられるようになっている。アンダーカバー61には一対の塞ぎ壁63を突設してあり、塞ぎ壁63はアンダーカバー61を本体43に取り付けた時、ボルト締め用開口部59を塞ぐようになっている。
【0011】
溝部49の底面には周壁53を挟む一対の端子挿入孔65を穿設してあり、端子挿入孔65はボルト締め用開口部59に連通している。端子挿入孔65は、図2に示すように周壁53を越えヒュージブルリンク収容空間51の内側へ拡げて形成してある。従って、端子挿入孔65における周壁53の下端は、クランク状に屈曲した段部67となっている。
【0012】
端子挿入孔65には、直角曲げ螺合端子69が挿入される。直角曲げ螺合端子69は、ボルト孔71の穿設された電気接触部73が、電線保持部75に対して直角に屈曲されている。直角曲げ螺合端子69は、この電気接触部73を端子挿入孔65に挿入してヒュージブルリンク57の電気接触部55と接続される。
【0013】
このように構成した電気接続箱の端子取付け構造の作用を説明する。
ヒュージブルリンク収容空間51にヒュージブルリンク57を挿入すると、一対の電気接触部55が本体43の内部に垂下し、ボルト締め用開口部59から露出した状態となる。
【0014】
直角曲げ螺合端子69の電気接触部73を端子挿入孔65に挿入し、直角曲げ螺合端子69全体をヒュージブルリンク収容空間51側に押し込むと、直角曲げ螺合端子69の電気接触部73がヒュージブルリンク57の電気接触部55に当接する。この時、同時に直角曲げ螺合端子69の屈曲部69aが、周壁53の段部67に上方から当接され、直角曲げ螺合端子69の上下方向の移動が規制される。これにより、直角曲げ螺合端子69は、手による保持なしでボルト孔71が電気接触部55のボルト孔56に一致した位置で位置決めされる。なお、直角曲げ螺合端子69に接続した電線70は、溝部49に形成した不図示の挿通穴を介して、本体43の内部から導出される。
【0015】
ボルト孔同士の一致した直角曲げ螺合端子69とヒュージブルリンク57の電気接触部55とは、ボルト締め用開口部59から挿入されるボルト77により一体に螺着される。なお、直角曲げ螺合端子69と電気接触部55との螺着は、電気接触部55にボルト77を直接螺合することにより、又はヒュージブルリンク収容空間51に配設した不図示のナットにボルト77を螺合することにより行うことができる。
【0016】
次いで、アンダーカバー61を本体43の下面側に取り付けることで、ボルト締め用開口部59が塞がれ、アッパーカバー79を本体43の上面に取り付けることで、本体43の上面が覆われて電気接続箱41への直角曲げ螺合端子69の取付けが完了する。
【0017】
上述の電気接続箱の端子取付け構造によれば、本体43の上面に、周壁53を越えてヒュージブルリンク収容空間51の内側へ拡がる端子挿入孔65を穿設したので、直角曲げ螺合端子69をこの端子挿入孔65に挿入した時、直角曲げ螺合端子69の屈曲部69aを周壁53の段部67に当接させて、上下方向の移動を規制して直角曲げ螺合端子69を所定位置に保持することができる。
【0018】
また、ボルト締めスペースを、本体43の外側壁45、47にボルト締め用開口部59として最小に形成することができるので、図5に示したボルト締めスペースを大きく形成しなければならない従来の構造に比べて、電気接続箱41の形状を簡素なものにでき、防水性も向上させることができる。
【0019】
なお、上述の実施形態では、本体43の上面に溝部49を形成し、この溝部49の底面に端子挿入孔65を穿設したが、本発明の端子取付け構造は、溝部49を形成せず、本体43の上面に直接、周壁53及び端子挿入孔65を設けるものであってもよい。
【0020】
【発明の効果】
以上詳細に説明したように、本発明に係る電気接続箱の端子取付け構造は、アンダーカバー、本体、および当該本体の上面に取り付けられるアッパーカバー、を有する電気接続箱の端子取付け構造であって、前記本体の上面に形成された、前記本体の直交する外側壁の面に対して傾斜する溝部と、前記溝部の中央に位置し、且つ前記本体の上面に配設されたヒュージブルリンク収容空間と、前記溝部に立設され、前記本体の上面から突出し、且つ前記ヒュージブルリンク収容空間を囲む周壁と、ボルトによりヒュージブルリンクの電気接触部と直角曲げ螺合端子の電気接触部とを接続するために設けられた、前記本体の直交する外側壁に形成され、且つ前記ヒュージブルリンク収容空間へ連通するボルト締め用開口部と、前記アンダーカバーを前記本体に取り付けた時、前記ボルト締め用開口部を塞ぐために前記アンダーカバーに設けられた一対の塞ぎ壁と、を備え、前記ボルト締め用開口部に連通するとともに、前記周壁を越えて前記ヒュージブルリンク収容空間の内側へ拡がる端子挿入孔を前記周壁の外側の前記溝部の底面に穿設し、前記端子挿入孔における前記周壁の下端にクランク状に屈曲した段部を形成し、そして電線に接続された前記直角曲げ螺合端子の電気接触部を前記端子挿入孔に挿入したので、直角曲げ螺合端子を端子挿入孔に挿入した時、直角曲げ螺合端子の屈曲部を周壁の段部に当接させて、直角曲げ螺合端子を保持することができる。この結果、手による螺合端子の保持が不要となり、端子取付け作業性を向上させることができる。

[Prior art]
The fusible link has a different type depending on the rated current, and a terminal-fitting type is used for the one having a low current characteristic of 30 to 50 A, but a high current characteristic of 60 to 100 A is required. As shown in FIG. 3, a screw-type fusible link 5 in which a bolt hole 3 is formed in the electrical contact portion 1 is used.
[0003]
An example of an electrical junction box that accommodates this type of screwed fusible link 5 is shown in FIG. In this electrical connection box 9, a fusible link housing portion 13 is formed on the upper surface of the main body 11, and a concave portion 15 in which the electrical contact portion 1 of the screw type fusible link 5 housed in the fusible link housing portion 13 is exposed. Is formed on the side. A nut 17 whose center coincides with the bolt hole 3 is disposed between the electrical contact portion 1 and the main body 11. In this electrical connection box 9, the round terminal 23, which is an external power supply terminal, is aligned with the bolt hole 3 of the screw-type fusible link 5, and then the bolt 25 is screwed into the nut 17, thereby forming the round terminal 23. Was attached to the electrical contact portion 1.
[0004]
However, in this electrical junction box 9, one electrical contact portion 1 can be screwed with the bolt 3 from the outside of the main body 11, but the other electrical contact portion 1 must be screwed with the bolt 25 from the inside of the main body 11. There was a problem with poor workability.
In order to eliminate such a deterioration in workability caused by the bolt insertion direction, for example, a terminal mounting structure for an electrical connection box shown in FIG. 5 has been proposed. The electrical junction box 31 is formed by notching the corners of the orthogonal outer walls 33a and 33b of the main body 33 to form a corner outer wall 35 that is inclined with respect to the surfaces of the outer walls 33a and 33b. A projecting portion 37 having orthogonal outer walls is provided, and the housing portion 39 of the screw type fusible link 5 is provided on the projecting portion 37. Therefore, according to this electrical junction box 31, both of the pair of electrical contact portions 1 can be screwed into the bolts 25 from the outside of the main body 33 to attach the round terminal 23 to the electrical contact portion 1.
[0005]
[Problems to be solved by the invention]
However, the above-described electrical junction box 31 has a round shape, although both bolts 25 screwed into the electrical contact portion 1 can be screwed from the outside of the main body 11 and workability degradation due to the bolt insertion direction can be eliminated. In order to attach the terminal 23 to the electrical contact portion 1, the round terminal 23 pulled up from the main body 33 must be held with one hand and bolted with the other hand, resulting in poor workability. It was.
The present invention has been made in view of the above circumstances, and provides a terminal mounting structure for an electrical junction box that can be bolted without manually holding a terminal to be mounted on an electrical contact portion of a screw-type fusible link. The purpose is to improve the terminal mounting workability.
