A fuse mounting structure and a batter system are provided according to the present application, the fuse mounting structure is used for mounting a fuse to a battery box, and includes a drawer and a fuse base; where the fuse base is mounted in the battery box, and the drawer is used for mounting the fuse; the drawer is provided with a guide device in a sliding fit with the fuse base, so as to guide the drawer to be inserted into the fuse base. According to the fuse mounting structure, the guide device is arranged on the drawer, the guide device guides the drawer with fuse when the drawer enters the fuse base, there is no need to align the plug-in holes, which realizes blind insertion of fuses and reduces the workload of fuse insertion.

The present invention provides a multiple fuse device that is compatible with various ratings and reduces an increase in manufacturing cost. A multiple fuse device includes an input terminal, an external terminal, a bus bar that includes a circuit portion disposed between the input terminal and the external terminal, and a housing that covers the bus bar. The external terminal includes an integral external terminal integrated with the circuit portion with a fusible portion interposed between the integral external terminal and the circuit portion, and a fuse-side external terminal that pairs up with a fuse connection terminal connected to the circuit portion. The fuse connection terminal and the fuse-side external terminal provided in a pair hold a fuse exteriorly in a removable manner, the fuse having a fusible portion connected between the fuse connection terminal and the fuse-side external terminal.

An electrical junction box includes a case body having a plurality of connector portions, a power supply side circuit board accommodated in the case body and a spare connector mounting portion provided in an upper portion of the case body and configured such that a spare connector is attached to and detached from the spare connector mounting portion. The spare connector includes a fuse configured to electrically connect the power supply side circuit board to a device side terminal connected to an end of an electric wire configured to be electrically connected to an electronic device.

The present invention provides a fuse unit which facilitates a work such as inspection and a method of manufacturing the fuse unit. Disclosed is a method of manufacturing a fuse unit, which has a metal part including an input terminal and an external connection terminal and a connector part for attaching an external terminal C3 to the external connection terminal and is manufactured by integrating the metal part and a resin covering body by insert molding. In this manufacturing method, the metal part and the resin covering body are integrated by insert molding such that a distal end of the external connection terminal of the metal part protrudes from the resin covering body, and then, the connector part separate from the resin covering body is attached to the resin covering body so that the external connection terminal protruding from the resin covering body can be connected to the external terminal C3.

A fuse cutout insulator for use in power distribution systems includes three electrically conductive pieces spaced apart and encapsulated by a dielectric material. The conductive components include a top hood, bottom pin, and central pin. The central pin is generally tube shaped and includes an outwardly extending flange to facilitate attachment of the fuse cutout to a utility pole. The top hood and bottom hinge include the traditional components for operable holding of a fuse tube member. The top hood and bottom hinge are accepted in opposite ends of the central pins bore and sealed in spaced relationship during manufacturing by the dielectric material added for fabricating the weathersheds.

The present invention provides a multiple fuse device that is compatible with various ratings and reduces an increase in manufacturing cost. A multiple fuse device includes an input terminal, an external terminal, a bus bar that includes a circuit portion disposed between the input terminal and the external terminal, and a housing that covers the bus bar. The external terminal includes an integral external terminal integrated with the circuit portion with a fusible portion interposed between the integral external terminal and the circuit portion, and a fuse-side external terminal that pairs up with a fuse connection terminal connected to the circuit portion. The fuse connection terminal and the fuse-side external terminal provided in a pair hold a fuse exteriorly in a removable manner, the fuse having a fusible portion connected between the fuse connection terminal and the fuse-side external terminal.

A fuse unit includes: a bus bar including a plurality of fusible parts interposed between a power supply side terminal and a plurality of load side terminals; and an insulating resin portion formed by insert molding using the bus bar as an insert component. The insulating resin portion includes: first and second resin portions respectively arranged at peripheries on the sides of the power supply side terminal and the load side terminals with respect to the fusible parts; and a plurality of coupling portions coupling the first resin portion and the second resin portion in a position outside each of the fusible parts. Each of the coupling portions is formed such that a reinforcement portion having a lower heat shrinkage rate than the insulating resin portion and having a higher strength than the insulating resin portion is an insert component. The reinforcement portion is provided using the bus bar.

A current breaker for automotive safety systems has a separating punch and a conductor formed with at least one localized decrease in thickness constituting a weakened separating point severable by the separating punch. This current breaker is made by overmolding the conductor in a plastic-injection mold with an encapsulation by a method having a first step of forming the separating point of the conductor in the plastic-injection mold before or during overmolding and a second step of forming with the mold above and below the conductor in the encapsulation a passage fully exposing the separating point and dimensioned to hold the separating punch.
