Abstract
The utility model relates to a plug fuse, which comprises cylindrical insulators with identical wall thickness, conductive end covers arranged at two ends of each insulator, fuse elements stretching and penetrating through the insulators and electrically connected with the conductive end covers and eyelets arranged between the insulators and the conductive end covers. The middle of each eyelet is arranged to be a hollow area. Compared with the prior art, by means of arrangement of the insulators, the conductive end covers, the fuse elements and the eyelets, the plug fuse improves production efficiency of products and lowers production cost simultaneously while ensuring characteristics of the products.
Description
Technical field
The utility model relates to a kind of plug fuse.
Background technology
Fuse is widely used in the overcurrent protective device, and it is used for open circuit and prevents that related elements from having break current to flow through circuit.The resistance wire of some type comprises an insulator with conduction end cap, and the conduction end cap is connected with it at the two ends of insulator.Electrical fuse element extends through this insulator and is electrically connected with end cap, and when end cap was connected with power-on circuit, this circuit passed through this electrical fuse element fully like this.In case a scheduled current this circuit of flowing through is arranged, the just fusing of this electrical fuse element, decompose or other disconnect mode, and then interrupt current path, and open circuit is not so that load-side electric device and equipment can flow through break current through this fuse.For example, often adopt fuse in the electric equipment plug in Britain.The fuse of these types is called the mini-insurance fiber tube sometimes.BP No.1474695 discloses a kind of fuse of the cylindrical end cap of identical wall thickness substantially that has.Yet this fuse production technology is difficult to automation, needs too much manual intervention production, and very lost labor and material during production cause cost very high.
Summary of the invention
The technical problem that the utility model will solve provides a kind of lifting production efficient, the plug fuse that reduces production costs simultaneously.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: this plug fuse; Comprise cylindrical insulator, and be arranged on the conduction end cap at insulator two ends with identical wall thickness, and the electrical fuse element that extends through this insulator and be electrically connected with the conduction end cap; And be arranged on the corn between insulator and the conduction end cap, be set to vacancy section in the middle of the said corn.
Further, said insulator is a porcelain tube.
Further, said porcelain tube is provided with quartz sand.
Further, said conduction end cap is the copper cap.
The plug fuse of the utility model owing to be provided with insulator, conduction end cap, electrical fuse element and corn, relative to existing technologies, when guaranteeing product performance, has promoted production efficient, has reduced production cost simultaneously.
Description of drawings
Fig. 1 is the three-dimensional exploded view of the utility model plug fuse;
Fig. 2 is the cutaway view of the utility model plug fuse.
Embodiment
In the present embodiment; See figures.1.and.2, said plug fuse comprises the cylindrical insulator 1 with identical wall thickness; And be arranged on the conduction end cap 2 at insulator 1 two ends; And the electrical fuse element 3 that extends through this insulator 1 and be electrically connected with conduction end cap 2, and be arranged on the corn 4 between insulator 1 and the conduction end cap 2, be set to vacancy section in the middle of the said corn 4; Owing to be provided with insulator 1, conduction end cap 2, electrical fuse element 3 and corn 4, relative to existing technologies, when guaranteeing product performance, promoted production efficient, reduced production cost simultaneously.
Wherein, said insulator 1 is a porcelain tube, also can be other insulating material certainly, and said porcelain tube is provided with quartz sand 5.Said conduction end cap 2 is the copper cap, and said copper cap is arranged on the two ends of porcelain tube, is provided with electrical fuse element 3 between two copper caps.
The plug fuse of the utility model owing to be provided with insulator, conduction end cap, electrical fuse element and corn, relative to existing technologies, when guaranteeing product performance, has promoted production efficient, has reduced production cost simultaneously.
Below the utility model is done a detailed description; The above is merely the preferred embodiment of the utility model, when not limiting the utility model practical range; Be allly to do impartial change and modify, all should still belong in the utility model covering scope according to the application's scope.
