A multi-load fuse block, which receives insertion of at least two safety fuses therein, includes: a housing, a first surface of the housing configured with a first fuse slot and at least one second fuse slot; a conductive joint, configured on a second surface of the housing, and in electric connection with the first fuse slot; a first load conductive wire, configured on a third surface of the housing; and a second load conductive wire, configured on a fourth surface of the housing, where the first fuse slot and second fuse slot allow a plurality of safety fuses to be inserted therein or separated therefrom. The first load conductive wires and second load conductive wires of the housing can provide electric connection for automotive electronics, allowing the safety fuses to be in electric connection with more automotive electronics so as to protect them from overcurrent.

Provided herein are approaches for securing an electrical protection device (e.g., a fuse). In one approach, an apparatus includes a conductor and a terminal coupling the conductor to the fuse, wherein the terminal includes an end cap having a cavity for receiving and securing the conductor, and a set of contact elements extending from a base member. The base member may be coupled to the end cap, and a body of the fuse may be coupled to the base member. In some approaches, a fuse blade of the fuse is disposed between the set of contact elements. In some approaches, the apparatus further includes a cover adjacent the terminal, wherein the cover is configured to engage the contact elements to increase a contact force and electrical connection between the set of contact elements and the fuse blade.

An electric connection assembly comprises a connector, a first wire, a second wire, and a fuse. The connector has a housing, a first conductive contact disposed in the housing, and a second conductive contact disposed in the housing. The first wire has a first end electrically connected to the first conductive contact and an opposite second end electrically connected to a first electrode of a load. The second wire has a first end electrically connected to the second conductive contact and an opposite second end electrically connected to a second electrode of the load. The fuse is connected in series with the second wire.

A novel fuse joint may be incorporated into a wire harness for use in solar energy installations. The novel fuse joint interfaces an in-line fuse with the middle portion of a wire segment at one end of the fuse, and with a wire end at the other end of the fuse. In this manner the number of connection points required to achieve in-line fuse functionality is decreased, thereby improving safety and conductivity over conventional in-line fuses. The fuse is undermolded, and the undermold is overmolded in situ, thereby yielding a double molded fuse joint. The novel fuse joint may be incorporated into a wire harness with conventional in-line fuses.

A fuse end cap for providing an electrical connection between a fuse and an electrical conductor. The fuse end cap may include a mounting cuff defining a first cavity that is adapted to receive a fuse body. The mounting cuff may be configured to be mounted to the fuse body by friction fit, for example. The fuse end cap may further include a terminal defining a second cavity adapted to receive a conductor. The terminal may be configured to be crimped about the conductor to retain the conductor within the second cavity.

Embodiments disclose a plug-in fuse element comprising a strip-shaped sheet metal part having a first end section, a second end section, and an interposed center section, wherein the first end section is a flat plug-in contact; the second end section is a connecting region configured to connect to a stranded conductor, and the center section is an overcurrent protection device. In some embodiments, a stranded conductor is connected on at least one end to a connecting region of at least one plug-in fuse element. In some embodiments, a wiring system includes at least one stranded conductor connected via a flat plug-in contact of a plug-in fuse element to a flat conductor. In some embodiments, a vehicle comprises the at least one wiring system.

A bus bar connector with a replaceable fuse are provided. A first terminal assembly inside the casing includes a first connecting element and plural first resilient contacts electrically connected with the first connecting element. A second terminal assembly inside the casing includes a second connecting element and plural second resilient contacts. An end of the second connecting element is electrically connected with the plural second resilient contacts, and another end of the second connecting element extends to form a cable connecting portion. The first cable assembly includes a first cable body extending from at least one of the left and right sides of the casing, and a cable connection portion connected to one side of the first cable body. The fuse element is connected in series between the cable connection portion and the first connecting element. The second cable assembly is electrically connected to the cable connecting portion.

Techniques and apparatuses for forming electrical connection are presented in which an apparatus may include an in-line fuse having terminals comprising terminal exterior surfaces and terminal recesses, and electrical cables comprising a conductor and a insulation sleeve and having an exposed portion and an unexposed portion. The exposed portion of an electrical cable is at least partially inserted into a respective terminal recess of the in-line fuse. The apparatus may further comprise one or more temperature-activated sealing members that circumferentially surround and form a seal against portions of the terminal exterior surfaces of the in-line fuse and portions of the insulation sleeves of the electrical cables. The apparatus may also comprise an inner mold encapsulating the in-line fuse and at least partially of the one or more temperature-activated sealing members, and an outer mold encapsulating the inner mold.

An electrical power supply cable (10) for a photovoltaic installation includes an electrical conductor (12) having at least two electrical conductor portions (20, 22) and a fuse (24) arranged between the at least two electrical conductor portions. The at least one fuse electrically links the at least two electrical conductor portions. The cable (10) further has a protection element (30, 40, 50, 60) overmolded around the fuse and forming an electrical insulation layer, the protection element having at least one overthickness at at least one end portion (34, 36) of the protection element (30).
