Abstract

The utility model more particularly relates to a high voltage fuse module, which comprises a casing with a containing cavity and a fuse. The casing has an inducting opening and an educing opening respectively. A terminal is positioned at the educing opening, while an insert is arranged at the inducting opening. An end of the fuse is connected into a through hole on the insert, and the other end of the fuse is connected with an end of a spring. The other end of the spring is provided with a hook buckled on a clasp part of the terminal, so that the high voltage conducting wire and the two terminals are saved; therefore, the cost is reduced. For the fuse is directly protected by the plastic casing, the glass tube structure is reduced, so that the cost is saved. For the fuse, of which the both ends are respectively arranged onto the insert and the terminal, is connected with the spring, the creepage distance of the gap can be guaranteed by making use of the recovery property of the spring when the fuse is broken, and the fire is not being stricken under the high voltage, so that the safe operation of the equipment can be ensured.

Description

The high voltage safety tube assembly

Technical field

The utility model is specifically related to a kind of high voltage safety tube assembly.

Background technology

On the existing market, the general structure of high pressure Arming Assembly is to be provided with cavity volume in shell and the shell, be placed with protective tube in the cavity volume, the two ends of protective tube are connected with socket, the socket other end connects high-voltage conducting wires, and high-voltage conducting wires extends outside the shell splicing ear on the end of its high-voltage conducting wires extension from the export mouth and the introducing port at shell two ends, the above-mentioned weak point that also exists: 1, the high-voltage conducting wires two ends need terminal to link to each other, and increase manufacturing cost; 2, because of directly using glass tube, cause, strengthen product cost core component fuse multiple protective.

Summary of the invention

The utility model is for solving the aforesaid drawbacks, and a kind of cost, high voltage safety tube assembly simple in structure saved is provided.

For achieving the above object: comprise housing and fuse, and cavity volume arranged on the housing, housing has introducing port and export mouth respectively, export mouth is fixed with terminal, described introducing port is fixed with inserted sheet, and fuse one end is connected on the inserted sheet in the set through hole, and the fuse other end is connected in spring one end, on the spring other end hook is arranged, hook is buckled on the hook part of terminal.

On the described cavity volume inwall locating piece is arranged, the inserted sheet side has recess, and its locating piece is embedded in the recess.

Described terminal and inserted sheet have location hole, and the cavity volume bottom is provided with reference column, and reference column passes its location hole.

Described fuse one end passes the set through hole of inserted sheet and twines on the aluminum component, and aluminum component is positioned on the through hole bottom surface of inserted sheet.

The utility model beneficial effect: two terminals 1, saving high-voltage conducting wires and connection high-voltage conducting wires; Thereby saving cost; 2, directly fuse is protected, reduced the glass tube structure, thereby save cost by plastic casing; 3, fuse connects with spring, makes two ends be separately fixed on inserted sheet and the terminal, when the fuse go splits, utilizes spring to reclaim characteristics, guarantees the creepage distance of gap, does not under high pressure strike sparks, and guarantees to make device security to use.
