CN2737002Y - Combined type safety plug with fuse - Google Patents

Abstract

The utility model relates to a combined type safety plug with fuse, comprising a body and an involutory upper cover. By mainly utilizing simple combination conformation, a ground wire terminal and a waterline terminal can be simply and respectively locked and fixed with the ground wire and the waterline in an electric wire, which can form conducting; according to the characteristic of convenient loading and unloading of the utility model, the state that a live wire, a fuse and a live wire terminal can mutually conduct can be realized simply. The conformation of the utility model is that diaphragms are provided between body corresponding terminals, which can prevent danger because of short circuit generated by core wires mutually touching caused by dropping of core wires on each terminal (the dropping reason can be that a bonding point is peeled off cause of oxidation for a long time, or man-made construction and assemblage is uncertainty or core wires get loose because of being used for a long time). The upper cover is corresponding to screws and a clip of lock-made core wires, and barrier chips are arranged on proper space on the end head of screws to form an effective limitation for preventing screws from getting loose; the utility model can avoid the danger of short circuit generated by screwsoptionally rolling in the inner of the plug cavity, which can raise safe effect.

Description

The safety plug of composite type tool fuse

Technical field

The utility model relates to a kind of safety plug of composite type tool fuse, particularly a kind of plug configuration that fuse can be contained in plug inside.

Background technology

General daily life mainly is that the mat wire and plug engages with socket with the power source of industrial facility, and conduction current is for use.The electricity consumption facility is equally also brought the misgivings of Electrical Safety, because electrical load is too highly to cause that easily electric wire cocks off, even cause fire, therefore how one strain to be arranged for electrical load, many countries have every security regulations and specification to be called for short " safety " surely, not only at this domestic production firm, also to the employed plug of import electrical equipment or simple plug product with and parts (part) standard.For example Bu Fen Britain's plug inside is provided with the design of fuse, and this kind fuse is a tubular body usually, changes or installs so that get.

In addition, though because many plugs have the fuse that meets safety requirements, yet its assembling, and lack one and design and be unfavorable for quick assembling with live wire in fire line terminal and the electric wire.

Heart yearn on each terminal may come off (its come off reason may because of oxidation with the passing of time dial from fixing point or because of artificial construction assembling really or use for a long time get loose), and cause between each bar heart yearn of electric wire, for want of isolate and touch mutually and produce short circuit, cause danger, so its fail safe still has improved space.

Summary of the invention

The purpose of this utility model provides a kind of safety plug of composite type tool fuse, can have the effect that assembling is more quick, convenient and take into account fail safe.
