The downstream delivering portion (20) includes: a connected terminal (23); a fuse portion (22a-22e) connected to the connected terminal (23); and a downstream output terminal (21a-21e) outputting the electric power via the fuse portion (22a-22e). The upstream delivering portion (10) and the downstream delivering portion (20) are independent members each other and are assembled to be integrated with each other to allow connecting the connecting terminal (13) and the connected terminal (23).

Abstract: A fusible link includes a power supply portion provided on a connection terminal that is formed of conductive metal and connects to a battery terminal; a circuit terminal that is formed of conductive metal in a plate shape and connects to a circuit; and a fuse element that is formed of conductive metal, connects the power supply portion and the circuit terminal in a belt-like shape that is narrower in width than the power supply portion and the circuit terminal, and fuses when a current equal to or greater than a threshold value flows, and in the fusible link, the fuse element has a shape projecting in an out-of-plane direction of a terminal mounting surface of a battery.

Abstract: A fuse unit includes a fuse unit body and a holding member being a different member from the fuse unit body. The fuse unit body includes a conductive fuse element having a hinge and first and second resin bodies provided across the hinge, and the fuse unit body is bendable at the hinge. The holding member engages with the first and second resin bodies of the fuse unit body bent at the hinge and maintains the fuse unit body in a bent state.

Abstract: A protection cover attachment structure of a battery-mounted fusible link unit includes a fusible link unit including a resin housing with a slide guide groove and a protection cover including an upper surface cover and side surface covers. The upper surface cover covers the upper surface of the resin housing and a battery post and a battery terminal. The side surface covers extend downward from a peripheral edge of the upper surface cover and cover the wire-attached terminals connected to the terminal sections of the fusible link unit and upper part of wires which are connected to the terminals and extended downward. When the protection cover is put over the resin housing, the slide guide grooves restricts the position of the protection cover and guides a side edge of at least one of the side surface covers downward.

Abstract: A fusible link unit includes a fusible link main body that includes a bus bar for connecting to a battery terminal, and a battery that has a battery post for connecting to the battery terminal. The fusible link main body includes an L-shaped housing having a first face and a second face which oppose two side surfaces forming a corner portion of the battery. The bus bar is connected to a fuse portion and is extended from the first face of the housing. Abutment portions for abutting against the side surfaces of the battery are provided on the first and second faces of the housing respectively.

Abstract: A hinge section including bending sections at both side edges of a band plate section is provided in center of a busbar. On both sides of the hinge section, two fuse circuit constituting plate sections are integrally formed to be linked thereto. Two resin housings are assembled by insert molding to the respective fuse circuit constituting plate sections, thus forming two bodies. The two bodies are pivoted in the same direction at the bending sections, and engagement units are locked, thus constituting a fusible link unit having a U-shaped plan view. The two bodies are engaged with each other in vicinity areas of the hinge section in the opposed surfaces of the opposed resin housing when the two bodies are pivoted. The fusible link unit also includes recessed and projected guides guiding the two resin housings to proper positions.

Abstract: In a terminal connection structure, a stud bolt is stood and inserted into a hole of a top plate portion of a terminal, and the nut is screwed and fastened to the stud bolt on the top plate, thus connecting the terminal to the stud bolt. A terminal accommodation section is formed by a tubular wall around the stud bolt. It has an opening and ribs at a part of a circumference thereof, and allows the terminal fixed to the stud bolt from above. The opening is formed so as to fit on a belt portion extending from the top plate portion toward a fixing portion of the terminal. The ribs are protruded on the protection wall. The ribs prevent the terminal from being detached upward when the terminal is being temporarily lifted. The ribs are arranged at different heights in a top-bottom direction of the stud bolt.

Abstract: A fuse 1 of the present invention includes a fuse body 32, a housing 33 which is made of an insulative resin, and receives and holds the fuse body therein, the fuse body being inserted into the housing through an upper opening in the housing, and a cover 34 which is made of an insulative resin, and covers the upper opening in the housing. Retaining portions 50, corresponding respectively to retaining claws 47 of a withdrawing jig for withdrawing the housing, are formed at a side surface of the housing. Therefore, the retaining claws of the withdrawing jig can be positively fixed to the housing, and a relatively large force is not required for the withdrawing operation, and therefore the withdrawing operation can be effected efficiently.
