It is locked to the fuse unit 20 by being locked by the portion (locking portion) 21b. An opening / closing operation flange 18 is integrally formed at the center of the rear end of the upper wall 12 of the cover body 11.

図３及び図４（ａ），（ｂ）に示すように、ヒューズユニット２０は、バッテリ３０と電源供給用の電線（図示省略）とを接続するものであり、バッテリ端子３２に導通接続される第１の端子板部２５ａと出力側電装回路（図示省略）に導通接続される第２の端子板部２５ｂを有したバスバー２５と、可溶体（ヒューズ）２６を収容する樹脂製のヒューズハウジング２１と、このヒューズハウジング２１の可溶体収容部２２に着脱自在に取り付けられる透明樹脂製のカバー２９とを、備えている。   As shown in FIGS. 3 and 4A and 4B, the fuse unit 20 connects the battery 30 and a power supply electric wire (not shown), and is electrically connected to the battery terminal 32. A bus bar 25 having a second terminal plate portion 25b that is conductively connected to the first terminal plate portion 25a and an output side electrical circuit (not shown), and a resin fuse housing 21 that houses a fusible body (fuse) 26. And a cover 29 made of a transparent resin that is detachably attached to the fusible member accommodating portion 22 of the fuse housing 21.

図３に示すように、ヒューズハウジング２１の可溶体収容部２２には、可溶体２６を収容してある。この可溶体２６は、第１の端子板部２５ａに接触して導通状態にされる第１の接触部２７ａと第２の端子板部２５ｂに接触して導通状態にされる第２の接触部２７ｂとを両側に有した導通板部２７と、この導通板部２７の中央の幅狭部２７ｃ上に溶着される金属チップ２８とを備えている。尚、可溶体収容部２２の上面側の開口部２２ａ内に透明樹脂製のカバー２９が着脱自在に取り付けられるようになっている。また、可溶体収容部２２の底面の周辺には空きスペースがあるため、可溶体収容部２２の底面にヒューズハウジング２１の側面２１ａに連通する水抜き孔２２ｂを形成してある。   As shown in FIG. 3, a fusible body 26 is accommodated in the fusible body accommodating portion 22 of the fuse housing 21. The fusible body 26 is in contact with the first terminal plate portion 25a and brought into a conductive state, and the second contact portion is brought into contact with the second terminal plate portion 25b and brought into a conductive state. 27b, and a metal chip 28 that is welded onto a narrow portion 27c at the center of the conduction plate 27. A cover 29 made of transparent resin is detachably attached in the opening 22a on the upper surface side of the fusible member accommodating portion 22. Further, since there is an empty space around the bottom surface of the fusible body housing portion 22, a drain hole 22 b communicating with the side surface 21 a of the fuse housing 21 is formed on the bottom surface of the fusible body housing portion 22.

図４（ｂ）に示すように、バッテリ端子３２は、バスバー２５の第１の端子板部２５ａにナット３５を介して締め付け接続されるボルト部３３と、バッテリ３０のバッテリポスト３１にナット３６を介して締め付け接続される環状部３４とを備えている。   As shown in FIG. 4B, the battery terminal 32 includes a bolt portion 33 that is tightened and connected to the first terminal plate portion 25 a of the bus bar 25 via a nut 35, and a nut 36 on the battery post 31 of the battery 30. And an annular portion 34 to be tightened and connected.

以上実施形態の保護カバー１０によれば、図４（ｂ）に示すように、バッテリ３０のバッテリポスト３１にバッテリ端子３２を介して接続されるヒューズユニット２０及びバッテリ端子３２をカバー本体１１で上方より覆い、このカバー本体１１のロック用凸部１６の角部１６ａをヒューズユニット２０のヒューズハウジング２１の側面２１ａの下端縁部２１ｂに係止して、カバー本体１１をヒューズユニット２０に固定する。   According to the protective cover 10 of the above embodiment, as shown in FIG. 4B, the fuse unit 20 and the battery terminal 32 connected to the battery post 31 of the battery 30 via the battery terminal 32 are moved upward by the cover body 11. The cover main body 11 is fixed to the fuse unit 20 by covering the corners 16 a of the lock projection 16 of the cover main body 11 with the lower edge 21 b of the side surface 21 a of the fuse housing 21 of the fuse unit 20.

この場合、カバー本体１１の上壁１２の両側壁１３，１３の各内面に突出したロック用凸部１６に相対向する位置には、ロック用凸部１６を樹脂で一体成形する際に加工抜き孔１７が形成され、この加工抜き孔１７から水がヒューズユニット２０のヒューズハウジング２１の可溶体収容部２２の内部に浸入するが、可溶体収容部２２の底面にはヒューズハウジング２１の側面２１ａに連通する水抜き孔２２ｂが形成されているため、この水抜き孔２２ｂより加工抜き孔１７から浸入した水を外部へスムーズに排出することができる。これにより、ヒューズユニット２０の内部に水が溜まることがなく、水溜まりによる電源供給用の電線等の電線の腐食やバスバー２５と可溶体２６の導通板部２７の腐食及び回路ショート等の故障、トラブルを防止することができる。   In this case, when the lock projection 16 is integrally formed with a resin, it is removed at a position opposite to the lock projection 16 protruding from the inner surfaces of the side walls 13 of the upper wall 12 of the cover body 11. A hole 17 is formed, and water enters the inside of the fusible body accommodating portion 22 of the fuse housing 21 of the fuse unit 20 from the processed hole 17, and the bottom surface of the fusible body accommodating portion 22 is formed on the side surface 21 a of the fuse housing 21. Since the drain hole 22b which communicates is formed, the water that has entered from the processed hole 17 can be smoothly discharged to the outside through the drain hole 22b. As a result, water does not collect inside the fuse unit 20, and corrosion such as corrosion of electric wires such as electric power supply wires due to the accumulation of water, corrosion of the conductive plate portion 27 of the bus bar 25 and the fusible body 26, and short circuit, etc. Can be prevented.

このように、カバー本体１１のロック用凸部１６を、水抜き孔２２ｂを有した可溶体収容部２２に相対向する位置に加工抜き孔１７を介して一体形成したことにより、可溶体収容部２２に水が溜まることを確実に防止することができ、水溜まりによる電線等の腐食や回路ショート等の故障、トラブルを簡単かつ確実に防止することができる。   Thus, by forming the locking convex portion 16 of the cover body 11 integrally with the fusible body housing portion 22 having the water draining hole 22b at a position opposite to the fusible body housing portion 22, the fusible body housing portion. It is possible to reliably prevent water from accumulating in 22, and it is possible to easily and surely prevent troubles and troubles such as corrosion of electric wires and the like due to the water pool and short circuit.

また、カバー本体１１のロック用凸部１６は、ヒューズユニット２０の側面２１ａの下端縁部２１ｂに係止される角部１６ａと、ロック用凸部１６の角部１６ａをヒューズユニット２０の側面２１ａの下端縁部２１ｂに案内する傾斜面部１６ｂを有していることにより、カバー本体１１のロック用凸部１６をヒューズユニット２０の側面２１ａの下端縁部２１ｂにスムーズに係止させて、カバー本体１１をヒューズユニット２０に簡単かつ確実に固定することができる。   Further, the locking convex portion 16 of the cover body 11 includes a corner portion 16 a that is locked to the lower end edge portion 21 b of the side surface 21 a of the fuse unit 20, and a corner portion 16 a of the locking convex portion 16 that is the side surface 21 a of the fuse unit 20. By having the inclined surface portion 16b that guides to the lower end edge portion 21b, the locking convex portion 16 of the cover body 11 is smoothly engaged with the lower end edge portion 21b of the side surface 21a of the fuse unit 20, and the cover body 11 can be easily and reliably fixed to the fuse unit 20.

尚、前記実施形態によれば、カバー本体の側壁の内面のロック用凸部と加工抜き孔を、ヒューズユニットのヒューズハウジングの可溶体収容部の前端側に相対向する位置に形成したが、ロック用凸部と加工抜き孔の形成位置は、ヒューズハウジングの可溶体収容部に相対向する範囲内であれば良い。   In addition, according to the said embodiment, although the convex part for a lock | rock on the inner surface of the side wall of a cover main body and the process punch hole were formed in the position which opposes the front-end side of the fusible body accommodating part of the fuse housing of a fuse unit, The formation position of the convex portion for machining and the processed hole may be within a range opposite to the fusible member accommodating portion of the fuse housing.

また、前記実施形態によれば、加工抜き孔と水抜き孔を上下方向において同じ位置に配置したが、左右方向に多少ずれるように形成しても良い。   Moreover, according to the said embodiment, although the process punching hole and the water draining hole were arrange | positioned in the same position in the up-down direction, you may form so that it may shift | deviate a little in the left-right direction.
