An attachment structure includes a housing and a plate-shaped cover attached to the housing. The cover has a locking portion to fix the cover to the housing. The housing has a locked portion engaged with the locking portion to regulate a movement of the cover in a direction separating from the housing. The attachment structure is configured to engage the locking portion and the locked portion at an engagement place while the cover and the housing are pressed each other in directions separating from each other at a pressing place distant from the engagement place, and to form a space between the cover and the housing in a region between the pressing place and the engagement place, when the cover is attached to the housing.

A fuse module including a mounting block formed of an electrically insulating material, the mounting block including a base portion and a wall portion disposed in a perpendicular relationship, the fuse module further including a fuse plate including an electrically conductive bus bar disposed on a bottom of the base portion, a fusible element electrically connected to the bus bar and disposed adjacent a front of the wall portion, and a fuse terminal electrically connected to the fusible element and disposed on a top of the base portion, the fuse module further including an electrically conductive terminal post extending from the top of the base portion and through the fuse terminal for facilitating connection to an electrical component.

A cover includes a top wall, a first side wall, a second side wall facing the first side wall, and a lock releasing portion. The first side wall includes a locking portion engageable with a locked portion of a covered body. The second side wall includes an opposed locking portion engageable with an opposed locked portion of the covered body. The lock releasing portion includes: a release operation portion inclined and projecting from the top wall in a cover mounting direction; and a connecting portion connecting the release operation portion with the first side wall around the locking portion or the release operation portion with the locking portion.

A power control system for a battery system of a vehicle includes a first contactor, a second contactor, N fuses and N vehicle loads. An active sacrificial protection device includes a third contactor and a first fuse. The active sacrificial protection device is connected to a positive or negative terminal of the battery system. A current sensor is configured to sense a measured load current flowing through one of the first contactor and the second contactor. A battery management module is configured to selectively close the third contactor to reduce current flowing through one of the first contactor or the second contactor and selectively open the one of the first contactor or the second contactor after closing the third contactor.

An example electrical interruption switch includes a casing, surrounding a contact unit defining current path therethrough. The contact unit has a first and second connection contact and a separation region. A current supplied to the contact unit via the first connection contact can be discharged therefrom via the second connection contact, or vice versa. The separation region includes a tubular element, an axial direction of which runs along an axis X, wherein the tubular element is separable into two parts along a plane perpendicular to the axis X, whereby the current is interrupted between the first and the second connection contact, wherein the tubular element has two opposite end regions along the direction of extent of the axis X, characterized in that the tubular element has a minimum wall thickness, which increases in each case in the direction of the end regions, in a region between the end regions.

A fuse box for a battery of a vehicle includes: a lower housing having a space in which a fuse is housed and a bus bar for electrically connecting the battery and the fuse is seated; a plate-shaped upper housing having a through hole formed at a central portion thereof and a first extending portion extending upward along a circumference of the through hole, where the upper housing is assembled on an upper side of the lower housing; and a fuse cover that is coupled to an upper side of the upper housing to cover the fuse exposed through the through hole of the upper housing.

An example electrical interruption switch includes a casing, surrounding a contact unit defining a current path therethrough. The contact unit has a first and second connection contact, a separation region and an upsetting region. A current supplied to the contact unit via the first connection contact, can be discharged via the second connection contact, or vice versa. The contact unit includes, or is connected to, a sabot configured to move from a starting to an end position via pressure; in the end position, the separation region is separated causing an insulation spacing between the first and second connection contacts. The upsetting region, upset during movement of the sabot from the starting to end positions, is formed as a tubular or rod-shaped element having an axis; the tubular or rod-shaped element has one or more tapers in its cross-sectional diameter; and the cross-sectional diameter is defined perpendicular to the axis.
