Fuse cavity structure includes fuses in which each of fusible elements for protecting a circuit from overcurrent is located between terminals, and a housing in which the fuses are mounted; a part of a wall of the housing which partitions the fuse and fuse is removed thereby to form a notch in the wall; and space is proved between the fuses. The notch is formed by notching the wall corresponding to at least a part of the fusible portion. The fuse has a head portion and jig engagement portions. A groove corresponding to the head portion and the jig engagement portions is provided within the housing. A wide-width portion is provided at the groove in correspondence to the width of the head portion of the fuse, and a narrow-width portion is provided at the groove in correspondence to the width of the jig engagement portion of the fuse which is narrower than the head portion. Another fuse having a different configuration from the fuse is provided at the housing in place of the fuse. A positioning portion for making it possible to assemble the another fuse to the housing in a normal state is provided at the groove. Such a fuse cavity structure is used for an electric connection box.
摘要:
A fuseholder and method for manufacturing thereof, the fuse holder having a cap and a molded body to receive a fuse. The fuse holder has a first contact located at one end of the body to engage one end of the fuse. A cylindrical second contact having opposed J-shaped slots is disposed near the other end of the body. Engaging the other end of the fuse is a connector having a pair of tabs receivable by the J-shaped slots to form a conductive bayonet connection between the connector and the second contact. Protrusions on the connector slidably engage the second contact to maintain conductive contact therebetween if the bayonet connection is broken. The fuse holder can be adapted by modifying the connector or by using an adaptor to accommodate shorter fuses. To manufacture the fuse holder, the first and second contacts are insert-molded into the body.
摘要:
A fusible link mounting structure, comprising a three-series fusible link formed by providing three pieces of fuse elements in series within a single common housing, a cavity having a mounting space formed according to a size of the common housing for the three-series fusible link, a plurality of tabs projected from a bottom of the cavity into the mounting space, and a monopole fusible link formed by providing a piece of fuse element in a single monopole housing, wherein a total length of the mounting space is set to be shorter than a sum of lengths of three-pieces of the monopole housings, and the tabs are arranged corresponding to positions of fuse terminals provided in the three-series fusible link, and also arranged at such positions that a plurality of the terminals do not interfere with the monopole housing, when the monopole fusible link is mounted in the cavity.
摘要:
An alarm circuit and method of monitoring a circuit protection device are disclosed. The alarm circuit includes a circuit protection device connected in series at an input voltage of a load. The alarm circuit also includes a programmable circuit connected in parallel to the circuit protection device and including an alarm signal. The programmable circuit is programmed to include a plurality of functional states, and at least one functional state corresponds to activation of the alarm signal. The at least one functional state activating the alarm signal corresponds with an interruption condition in the circuit protection device.
摘要:
A fuse incorporates a fusible element assembly and an auxiliary fusible element assembly in a solid arc extinguishing material configuration. The fusible element assembly has a first operating characteristic and the auxiliary fusible element has a second operating characteristic different than the first operating characteristic. An installation adapter may be used to adapt a fuse to a non-standard mounting for the fuse. The installation adapter may include first and second adapter members that secure to the fuse to provide contacts having an appropriate spatial relationship to engage the non-standard mounting. A fuse and an installation adapter may be packaged as a kit.
摘要:
A modular fuse carrier provides an insulating housing of standard form factor incorporating adapter bus bars having multiple mounting points for different fuse brackets at different separations. The adapter bus bars may be attached to connectors and/or bus bars in fixed configurations to allow standardization and pre-manufacture of electrical assemblies that remain amenable to a wide variety of different fuse types and capacities.
