Abstract:
The invention is a circuit protection device comprising a first and a second female terminal. The device further comprises a first fuse clip in electrical contact with the first fuse terminal and a second fuse clip in electrical contact with the second fuse terminal. A positive temperature coefficient element, preferably planar, is positioned between and makes electrical contact with both the first fuse clip and the second fuse clip. In a first embodiment, at least one of the first and second fuse clips is spring-loaded, i.e., has an inherent resiliency. In this same embodiment, portions of the first and second fuse clips overlap, and the positive temperature coefficient element is secured between the overlapping portions of the first and second fuse clips. In the second of the two preferred embodiments, the first fuse clip, the second fuse clip, and the positive temperature coefficient element are generally coplanar.
Abstract:
An injection molding heater system for heating molding resins or plastics includes a plurality of heaters for heating resin wherein each of the heaters is positioned adjacent a nozzle or manifold. The system also includes an electrical circuit which is connected with the heaters and carries electricity from a power source to each of the heaters in order to energize the heaters. A plurality of circuit breaking devices are incorporated in the circuit for discontinuing the flow of electricity through each of the electrical circuits for preventing circuit damage in case of overcurrent, surges or the like. At least one circuit breaker is positioned in each of the electrical circuits between the power source and each of the heaters.
Abstract:
The present invention is directed a circuit protection component including male and female cable connectors coupled to one another in a lightweight, easy to handle housing. A circuit protection device, such as a fuse, is mounted within the housing and arranged to electrically couple the male cable connector to the female cable connector. The housing can be easily installed at any location of a power distribution network by using the male and female connectors to couple one power cable to another power cable. Accordingly, a plurality of the circuit protection components can be strategically located at each branch or sub-branch circuit in a straightforward coupling of power cables feeding electric power to and forming the localized sections of the power distribution network.
Abstract:
In-line fuse holders for two-bladed fuses are disclosed which can be fastened in series to an electrical wire by severing the wire in which the holder is to be incorporated, inserting the severed ends of the wire into the holder, and mechanically fastening the wire securely in the holder. Various embodiments are shown including holders in which the wires are connected with sliding guillotine blades, and those in which fastening is secured by crimping. Several of the embodiments include cover flaps which hold fuses inserted in the holders securely in place.
Abstract:
An in-line fuse holder having a first body section into which an insulated conductor which has been cut is placed, there being piercing type terminals provided in a second body section to pierce the insulation and to make connection with the two ends of the cut conductor. The second body section contains a cartridge type whose conductive ends are held in clip-type terminals with the body of the fuse viewable through a cutout which permits a viewer to see if the fuse has been blown. The two sections of the body are formed as an integral unit connected by a hinge and a cover for the cut ends also can be formed at the same time as the body sections.
Abstract:
A fused plug wherein at least one wire of a line cord is connected to a prong member by means of a fuse assembly in which one end of a length of fuse wire or other fuse material is electrically connected as by soldering or crimping to a portion of the line cord wire from which the insulation has been removed, the length of fuse wire lying along the line cord wire and being secured to the insulative sheath thereof by means of a sleeve, which preferably serves to electrically connect the fuse assembly to the prong member. The sleeve may further comprise a tang for connection to the prong member, for instance, by soldering, or the sleeve may be connected to the prong member by ring clip means, or by means of a pigtail to be provided in electrical contact with the sleeve for connection to the prong member. The fuse assembly further comprises an outer insulative sheath that covers the electrical connection between the fuse wire and the line cord wire, and covers a portion of the sleeve. The outer insulative sheath is preferably made of a synthetic material that can be slipped over the line cord wire in the form of a piece of tubing and then shrunk into place by heating.
Abstract:
A fuse protects a decorative string set of series-connected miniature incandescent lamps from current overload. The fuse comprises a fuse body insertable into a compartment of a fuse socket wherein electrical contacts are located. A fuse wire which is supported on the body includes a central wire portion mounted in a bore of the body, a pair of intermediate wire portions extending through passageways formed in the body, and a pair of exposed end wire portions bent rearwardly to engage the outer surface of the body. A keying stud and recess are respectively formed on the socket and body to reliably establish an electro-mechanical connection between the exposed end wire portions and the contacts upon insertion of the body into the socket. A fuse plug is inserted into the bore to thereby enclose the central wire portion. All of the fuse parts, exclusive of the wire, are made of fire-resistant and electrically-insulating materials so that the central wire portion is enclosed in an environment resistant to heat and fire. The fuse is easy to manufacture and to assemble, particularly in mass production.
