Abstract
The utility model discloses a surge protector of high security, include the shell that forms by the flame retardant plastics structure and set up the piezo -resistor in the shell, piezo -resistor is connected with one and breaks away from the mechanism to be equipped with the ceramic layer with the shell medial surface of piezo -resistor contact, piezo -resistor sets up and hugs closely with the ceramic layer on the ceramic layer. The utility model discloses simple structure has high -performance protect function.
Description
Technical field
The utility model relates to a kind of surge protector, particularly a kind of surge protector of high security.
Background technology
The body junction component of surge protector of the prior art is all made up of flame retardant plastics; but under extreme fault condition; key components and parts (piezo-resistance) can produce unmanageable high temperature instantaneously; plastics at high temperature there will be distortion; thus make releasing mechanism block akinesia; and then can because the short circuit current continued, localized hyperthermia causes burning on fire.
Utility model content
For above-mentioned the deficiencies in the prior art part, the utility model provides a kind of surge protector of high security, efficiently solves above-mentioned prior art Problems existing.
To achieve these goals; the technical solution adopted in the utility model is: a kind of surge protector of high security; comprise the shell constructed by flame retardant plastics and the piezo-resistance arranged in the enclosure; described piezo-resistance is connected with a releasing mechanism; and the shell medial surface contacted with piezo-resistance is provided with ceramic layer, piezo-resistance is arranged on ceramic layer to be close to ceramic layer.
As preferably, described shell contacts one side with piezo-resistance whole in ceramic layer structure.
As preferably, the position near piezo-resistance on described ceramic layer is provided with fire-retardant baffle plate.
As preferably, described fire-retardant baffle plate is four pieces, to piezo-resistance in surrounding structure.
As preferably, described fire-retardant baffle plate and ceramic layer are vertical stratification.
Compared with prior art, the beneficial effect of this utility model: the utility model, by structural improvement, by arranging ceramic layer, making piezo-resistance generate heat and indeformable, thus making releasing mechanism safe escape, reaching the object of high security; And by arranging fire-retardant baffle plate and fire-retardant baffle plate to piezo-resistance in surrounding structure, the high temperature of piezo-resistance is not leaked on the flame retardant plastics of shell.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is end view of the present utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
See Fig. 1-2, a kind of surge protector of high security, comprise the shell 1 constructed by flame retardant plastics and the piezo-resistance 3 be arranged in shell 1, described piezo-resistance 3 is connected with a releasing mechanism, and shell 1 medial surface contacted with piezo-resistance 3 is provided with ceramic layer 2, in the present embodiment, position near piezo-resistance 3 on described ceramic layer 2 is provided with fire-retardant baffle plate 5, described fire-retardant baffle plate 5 is four pieces, to piezo-resistance 3 in surrounding structure, described fire-retardant baffle plate 5 and ceramic layer 2 are in vertical stratification, and described shell 1 contacts one side with piezo-resistance 3 whole in ceramic layer 2 structure, piezo-resistance 3 is arranged on ceramic layer 2 to be close to ceramic layer 2.
Ceramic layer 2 in the utility model is 2-5mm, releasing mechanism in the utility model comprises linking springs 4, and be connected with piezo-resistance 3, when piezo-resistance 3 fault produces high temperature, fire-retardant baffle plate 5 to a certain degree can completely cut off the flame retardant plastic bed of material 6 of high temperature melting shell 1.
Claims (5)
