摘要： A lightweight industrial fuse has a housing and a conductive fuse. The housing has a first plastic half-housing and a second half-housing combined with each other. The conductive fuse is integrally formed and clamped between the first and second half-housing. The conductive fuse has a fusible body and two intermediary portions disposed within the housing, and two electrode portions exposed from two opposite ends of the housing. Thus, an enclosed accommodation cavity of the housing is defined through the combination of the first and second half-housing. A manufacturing process is simplified, and a manufacturing cost is decreased, and further a weight of the industrial fuse is effectively reduced.

摘要： An easy-to-assemble fuse has a fusible body, a socket, and a cover. The fusible body is engaged with the socket. The cover is covered on the socket and the fusible body and is engaged with the socket. By the engagement between the fusible body and the socket and the engagement between the socket and the cover, the fuse achieves the purpose of fast alignment and positioning. The fuse can be quickly assembled during the manufacturing process, thereby simplifying the manufacturing process, and reducing the production cost.

摘要： A protective element has a body, an inner connection layer, an outer connection layer, a heating layer and a low-melting-point alloy layer. The body is made of a single insulation material. The inner and outer connection layers are formed on two upper and lower surfaces of the body. The low-melting-point alloy layer is formed on the upper surface of the body and is electrically connected to the inner connection layer. The heating layer is mounted inside the body and is electrically connected to the low-melting-point alloy layer by the inner connection layer. The outer connection layer is electrically connected to the low-melting-point alloy layer and the heating layer. The outer connection layer is soldered on a power circuit. When the power circuit encounters overcurrent, the heating layer is heated to fuse the low-melting-point alloy layer faster. Thus, power circuit is cut to protect the power circuit.

摘要： An airtight surface mount fuse with a cavity has a housing, a conductive fuse, a cover and an encapsulant. The housing has an opening and an airtight inner space. The fusible element has a part disposed inside of the airtight inner space and another part exposed from the opening. The cover is configured to fit into the opening. The encapsulant encapsulates the housing, the cover and a segment of the exposing part of the fusible element. The other segment of the fusible element is exposed from the encapsulant. The inner space of the housing is encapsulated by the encapsulant and becomes airtight. The fusible element is disposed inside of the airtight inner space to prevent the hazard occurring from arc spark interacting with flammable gases when a fusible body of the fusible element is fused. It also ensures the fusible body is affected by the external environment.

摘要： A fuse includes a tubular body having two ends each having a first cap, which is formed with a through hole; a fusible and breakable unit including a first fusible filament arranged inside the tubular body and having two ends extending outward through the through holes respectively; and a plurality of second caps each of which has a surface that is formed with a recessed part and an opposite surface that is provided with a conductive wire. The recessed parts of the second caps are mounted to outer circumferences of the first caps. The two ends of the first fusible filament are respectively coupled between the first caps and the second caps corresponding thereto so as to extend a distance between the two ends of the first fusible filament and thus, preventing the occurrences of electrical arc after the first fusible filament is fused and broken.

摘要： A fuse line fixing structure of a fuse includes a base having first and second support sections. The first support section has two sides each forming a first wing and a first concave surface is formed between the first support section and the first wings. First and second electrodes are respectively arranged at two ends of the base. The first electrode includes a first curved plate arranged between the first support section and the first wings. The first curved plate has a convex engagement surface positioned against the first concave surface and a concave engagement surface facing toward an upper side of the first concave surface. The fuse line straddles between the first and second support sections and has an outer circumferential surface in mutual contact, through surface to surface engagement, with the concave engagement surface of the first curved plate.
