A circuit protection assembly (CPA) is disposed between a source of power and a circuit to be protected. The CPA comprises a mounting block having a bore extending therethrough and a recess cavity on a first surface of the mounting block. A post having a first end is disposed within the recess cavity and a body portion extends through the bore. The body portion configured to receive a terminal and the second end configured to receive a securing mechanism. A fuse having a centrally disposed aperture is configured to receive the body portion of the post and to receive the terminal for connection to a circuit to be protected. An insulator disposed on the terminal and disposed beneath the securing mechanism. The insulator configured to isolate the post from the terminal and the fuse while allowing the securing mechanism to apply an amount of torque.

A fusible link having a high-rated terminal group and a low-rated fuse box are provided. The low-rated fuse box has a power-source-side terminal connected to an auxiliary terminal of the fusible link, a load-side connection terminal to be connected to a load side, a holder configured to hold the power-source-side terminal and the load-side connection terminals, and a low-current fuse configured to electrically connect, when attached to the holder in a detachable manner, the power-source-side terminal and the load-side connection terminals to each other.

A locking assembly for a fuse box of a vehicle includes a base and a cover configured to be removably connected to the base. The base includes a projection extending outwardly from the base. An opening is disposed in the projection. The cover includes a locking member configured to be received by the opening in the projection when the cover is connected to the base. The cover is configured to rotate about a pivot axis of the locking member to disengage the locking member from the opening in the projection to remove the cover from the base.

A cover for a vehicle electrical system component, such as a pre-fuse assembly, that includes an integrated hinge and locking mechanism. The integrated hinge allows a pivoting cover portion to easily be rotated out of the way in order to give access to an underlying component (e.g., a jump post), while the integrated locking mechanism allows that same cover to be securely locked onto itself when no access is needed. The cover is not limited to a pre-fuse assembly and may be used with other vehicle electrical system components, such as a power distribution device (e.g., a power distribution box, an electrical connection box, a junction box assembly, etc.), a wire harness protector, etc.

An electrical device assembly and method to attach an isolated single stud fuse assembly to an electrical device are disclosed. The electrical device assembly consists of multiple studs, one or more of which is replaced with the isolated single stud fuse. A conductive copper landing zone receives an electrically isolated steel stud. When the landing pad assembly is orbital riveted into a plastic housing of the electrical device, the stud is locked into the housing permanently. Electrical devices such as disconnect switches and power distribution modules, both of which include multiple studs, are good candidates for being adapted with the single stud fuse assembly.

Disclosed are a fuse, a fuse box, and a fuse device capable of preventing insertion of wrong products into the box or device and persistent electric arc. In certain aspects, the fuse includes a pair of electro-conductive terminals, a fuse element having a fusion portion provided between the electro-conductive terminals, and an insulating housing mounted so as to cover at least a part of the fusion portion and the electro-conductive terminals, wherein a notch is provided on a lower-end side of the insulating housing, the notch is located between the pair of electro-conductive terminals and at a position that does not interfere with the shape of the fusion portion provided between the pair of electro-conductive terminals, and the notch is formed in a manner that a protrusion provided in a fuse box for housing the fuse can be fitted therein.

It is aimed to provide a fuse holder with a novel structure capable of improving insertion operability in the fuse holder for holding a plurality of fuses. A plurality of fuse holding portions (26a, 26b) are provided into which main body portions (16, 16) of fuses (12a, 12b) are to be mounted and in which lead portions (14, 14) of the fuses (12a, 12b) are held in a projecting state. Holding positions of the fuses (12a, 12b) by the plurality of fuse holding portions (26a, 26b) are made different from each other in a projecting direction of the lead portions (14) from the main body portions (16) in the fuses (12a, 12b).

The present invention provides a housing, fuse, and fuse box, with which it is possible to differentiate a multi-pole fusible link and prevent misassembly, while holding down costs. This housing is attached to a multi-pole fusible link contained within a containing part of a fuse box, and is provided with misassembly-preventing protrusions which are removable according to the type of multi-pole fusible link, the locations of the misassembly-preventing protrusions protrusions corresponding to the locations of recesses recesses which are provided to the containing part that is to contain the multi-pole fusible link, and in which the misassembly-preventing protrusions can be contained.

An exemplary embodiment of active/passive automotive fuse module in accordance with the present disclosure may include an electrically insulating base, a fuse plate including a bus bar portion disposed on a top surface of the base above a projectile cavity formed in the base, the fuse plate further including a fusible portion electrically connected to the bus bar portion and adapted to open when an amount of current flowing through the fuse plate exceeds a current rating of the active/passive automotive fuse module, the active/passive automotive fuse module further including a pyrotechnic interrupter (PI) disposed atop the base and including a projectile positioned above the bus bar portion, the PI configured to drive the projectile through the bus bar portion upon actuation of the PI.

A power relay assembly is provided. A power relay assembly according to an exemplary embodiment of the present invention comprises: a support plate having at least one electric element mounted on one surface thereof and including a plastic material having heat dissipation and insulation properties; and at least one bus bar electrically connected to the electric element and partially embedded in the support plate. Due to these features, since heat generated from the bus bar and the electric element is dissipated to the outside through the support plate, it is possible to prevent performance deterioration due to heat and breakage of electronic components.
