CN-224204090-U - Convenient installation mechanism for high-voltage fuse

Abstract

The utility model relates to the technical field of fuses, and provides a convenient installation mechanism for a high-voltage fuse. During installation, through inserting the picture peg in the slot, first triangle piece extrusion second triangle piece in the male, make second triangle piece upward movement, first spring stretches out and draws back, the slide bar upwards slides, when the picture peg inserts in place, first spring drives the second triangle piece and resets, make second triangle piece inconsistent with first triangle piece, it is spacing fixed to the picture peg, during the dismantlement, through upwards pulling the slide bar, the second triangle piece upwards moves, at this moment, pull out the picture peg from the slot, can accomplish the dismantlement to high voltage fuse, thereby realized not having need to use the instrument to install or dismantle the purpose of high voltage fuse, effectively prevented because of the elasticity of different mounting points is inconsistent, influence the problem emergence of whole system reliability.

Description

Convenient installation mechanism for high-voltage fuse Technical Field The utility model relates to the technical field of fuses, in particular to a convenient installation mechanism for a high-voltage fuse. Background The fuse is an electric appliance which fuses a melt by heat generated by the fuse when a current exceeds a predetermined value to open a circuit. The fuse is a current protector which is made up by using the principle that after the current exceeds a specified value for a period of time, the fuse body is melted by the heat generated by the fuse body so as to break the circuit. The fuse is widely applied to high-low voltage distribution systems, control systems and electric equipment, is used as a protector for short circuit and overcurrent, and is one of the most common protection devices. Known Chinese published patent (application number: CN 202122768280.9) discloses a self-locking high-voltage fuse, which comprises an insulated outer cylinder, an inner cylinder for accommodating a fuse tube or a fuse wire, and a self-locking mechanism, wherein the self-locking mechanism comprises a lock catch assembly and a socket lock cylinder, the lock catch assembly is arranged at the lower end of the outer cylinder, the socket lock cylinder is connected at the lower end of the inner cylinder, the socket lock cylinder and the inner cylinder form an assembly body, the assembly body can be inserted into or withdrawn from the outer cylinder and the lock catch assembly, and the socket lock cylinder and the lock catch assembly are matched to form the self-locking mechanism and are used for locking or unlocking the inner cylinder in the outer cylinder. The utility model adopts an internal and external closed structure and an automatic locking function, completely avoids the influence of natural environment and external factors on the electrical and mechanical properties of the high-voltage fuse, and has the unique advantages of convenient and quick fuse replacement, simple operation, reliability and durability. However, in the implementation of the related technology, the problem that the conventional self-locking high-voltage fuse is usually installed and fixed through bolts when the high-voltage fuse is installed is found, but the bolt fastening depends on experience of constructors, and if tools such as torque wrenches and the like are not used, the inconsistent tightness of different installation points can be caused, and the reliability of the whole system is affected, so that a convenient installation mechanism for the high-voltage fuse is provided.
