Abstract: An electric motor for driving a motor vehicle component, such as a fan motor for cooling cooling water, has a thermal fuse with a contact spring. The contact spring has attached ends that are connected to a conducting path section between which an interruption point is formed. The springy ends of the contact spring are in soldered contact with each other in a spring-biased manner. The thermal fuse is a fuse module with a plastic support in which the conducting path sections are partially embedded in such a way that the contact spring lies in a window opening in the support. Terminals of the conducting path sections protrude from the plastic support.

Abstract: A fuse unit is provided having a fuse element (2) in which a first terminal connecting part (4) and second terminal connecting parts (5) are formed and an insulative resin part (20) is formed on the outer surface of the fuse element (2) with insertion molding. Threaded bolt holes (10) are formed in the first terminal connecting part (4) and the second terminal connecting parts (5) of the fuse element (2). Bolts (30) are temporarily fixed to the fuse element (2) by being screwed into the threaded bolt holes (10), and the insulating resin part (20) is formed with insertion molding by using the fuse element (2) to which the bolts (30) are temporarily fixed as an inserted component.

Abstract: A fuse holder (20) is provided that can be installed in the place of a dropout fuse element in an electrical insulating unit (1). The fuse holder has an elongate electrically insulating body providing at least one electrically insulated elongate fuse housing in the form of a passage (21) associated with the body and adapted to receive a fuse wire (22) held under tension therein. The body can be installed in such insulating unit as a replacement to an existing dropout fuse element (5) and itself provides contacts enabling such a conventional dropout fuse element to be installed in the fuse holder body from which it can drop out when the fuse is blown. A switch arrangement is provided for maintaining a fuse in the passage in an inoperative condition whilst a dropout fuse element is functional and for automatically closing an electrical circuit through a fuse installed in said passage when the dropout fuse becomes blown and drops out of the fuse holder.

Abstract: A power circuit breaker having a simple structure with a small number of components is provided. The power circuit breaker includes: a circuit receiver which receives a pair of circuit terminals connected to an end of an opened power circuit; and a plug body having a fuse to be mounted on the circuit receiver to close the power circuit. In the fuse, a pair of terminals extending from a housing, which receives a fuse element of the fuse, is bent approximately at right angles at the middle of the terminal. The bent part is provided with a notch. A cross section of the terminal exposed within the notch is pressed by a jig, which fits with the notch, so that the fuse is press-fit into the plug body.

Abstract: A multiple fused junction with blown fuse indication which generally includes a main body, a fuse connected to the main body and a switch disposed within the main body. The main body has multiple cable ports extending outwardly therefrom. At least one of the ports is adapted for electrical connection with a feeder cable and another of the ports is adapted to receive a fuse. The fuse is removably connected to the fuse port of the main body and has an indicator rod movably disposed therein, which protrudes from an axial end of the fuse into the main body upon electrical interruption of the fuse. The switch is disposed within the main body adjacent the fuse port and is activated by the indicator rod of the fuse upon protrusion of the rod from the fuse to provide indication of electrical interruption of the fuse.

Abstract: A cable limiter includes a main body having a cavity. The cavity of the main body is structured to receive a replaceable fusible element. An annunciator is housed by the main body. The annunciator is structured to annunciate status of the replaceable fusible element.

Abstract: A panel mountable fuse holder for cartridge-type electrical fuses features a one-piece side terminal connection and a one-piece rear terminal connection. Both are configured for radial snap-in engagement with the fuse holder body. A novel capture mechanism in a sleeve disposed within an insertion knob assembly provides electrical contact to the forward fuse terminal without unduly stressing substantially misaligned caps. The capture mechanism also provides moderate rotational torque to the fuse during insertion, whereby the fuse is partially rotated to provide improved electrical contact to a planar ring structure integral with the rear terminal connection.

Abstract: A safety socket with easy fuse replacement device, specifically it covers a socket body and a cylinder used to house a number of protection fuses, the cylinder may be inserted into the annular guidance as provided on the socket body and used to shroud the cylinder whose center abound in insertion holes, characterized in that the center of the insertion hole is provided with a push-on switch such that it may be pressed to conduction once the socket is inserted into the insertion hole, in the event that a fuse is burnt and broken due to overloading, by giving a grip-turn to the cylinder the conserved fuse will replace the function of the broken fuse, and in this manner time and labor are saved, in the meantime, dangers due to replacement of a fuse and a fuse in use are eliminated.

Abstract: A high capacity change-over power supply fuse has an elongate fuse element holder, with fuse element mounting positions at each end. Sliding of the holder move one or the other of the fuse elements into contact with contact members mounted on the supply buses. The fuse element not in contact with the contact members is accessed through an aperture in a cover over the holder and contact members, a clip in cover fitting in the aperture. An aperture, is provided at each end of the cover for access to each fuse element when in a non-active position. Only the contact members need be silver plated, reducing the cost relative to conventional rotary change-over units.

Abstract: An electroluminescent display device includes at least two conductive leads spaced from each other with a light-emitting element electrically coupled between such leads. A transparent, insulating base is formed about and between the leads. The base encapsulates both the leads and the light-emitting element.At least one lateral portion of each lead extends beyond the base and substantially conforms to the configuration of the base. In conforming such lateral portions, they are preferably wrapped around the base and fixed to it. These lateral portions are arranged so that light from the light-emitting element may pass axially through the base and out of its ends. In addition, light may pass laterally out of the base.The device may also be used for circuit protection purposes. To so use the device, a protective element is electrically coupled between the leads so that upon the occurrence of an overload condition in an external circuit coupled to the lateral portions, the protective element decouples the leads.

Abstract: An indicating sectional two-part fuse is provided having a high-current current-limiting section, and a low-current expulsion section, mechanically connected together, and in electrical series, the low-current section utilizing a standard-type fuse-link, which may be replaced. The high-current current-limiting section may contain one or more current-limiting type fuse elements, supported by an interrupter rod within an enclosed casing filled with an arc-extinguishing granular material, and the low-current expulsion section of the fusible device may comprise an open-ended fuse tube, through which the standard fuse-link may extend, with the cable of the fuse-link extending out of the open end of the fuse tube.

Abstract: An indicating composite sectionalized fuse is provided having a high-current interrupting section, and a mechanically-connected detachable low-current interrupting section in series therewith, with the low-current interrupting section including a pull-away indicating fuse-link cable, which indicates externally a blown condition of the fuse. The low-current interrupting section is replaceable, following a low-current interruption, which has no effect upon the high-current interrupting section, the latter remaining intact and may be further used. During high-current interruption, both sections are fused, and collectively contribute together to a quick interruption of the connected electrical circuit, again there being an external indicated condition of the blown condition of the fuse by an ejection of the fuse-link cable.
