Abstract
The utility model is the varistor with fuse protecting device; it includes varistor ontology and the fuse protecting device that is located on varistor ontology; fuse protecting device includes fusible link, and two buckles that fusible link is clamped are additionally provided on fuse protecting device；One of them snaps connection electrode, another snaps connection pin, and fusible link is located between two buckles.The fuse protecting device of hollow out is set on varistor, and device for fusing disconnects more convenient under overpressure situation, does not interfere with the component on periphery, and the replacement of device for fusing is more convenient, and the secondary recovery for being conducive to resistor utilizes.
Description
Technical field
The utility model is related to component resistance common in electronic circuit, specifically carry fuse protecting device
Varistor.
Background technology
Varistor is a kind of resistance device with nonlinear wind vibration, be mainly used for when circuit bears overvoltage into
Row voltage clamping absorbs extra electric current to protect Sensitive Apparatus.In actual use, varistor is bearing larger pressure
When, more heat is will produce, or even will appear phenomena such as the exploding of catching fire caused by overvoltage, therefore, in production application
During, it needs that device for fusing is arranged on varistor, resistance device for fusing during there is overvoltage is allow to make
Circuit disconnects, and prevents resistance from further generating heat and even generates explosion.Existing fusible link is usually to be directly welded in pin and electricity
Between pole, and fusible link is sealed up for safekeeping by hot melt adhesive, in actual use, relatively due to scolding tin and the fusing point of hot melt adhesive
It is low, the fusing of fusible link can be impacted, and once fusible link, after fusing, resistor can not just carry out secondary recovery again
It utilizes, results in waste of resources.
Invention content
The utility model is the varistor with fuse protecting device, and the fusing that hollow out is arranged in it on varistor is protected
Protection unit, device for fusing disconnects more convenient under overpressure situation, does not interfere with the component on periphery, and device for fusing
It is more convenient to replace, and the secondary recovery for being conducive to resistor utilizes.
The utility model realizes that above-mentioned purpose uses following technical scheme：
Varistor with fuse protecting device, it includes varistor ontology and is located on varistor ontology
Fuse protecting device.
It is equipped with cricoid ceramic jacket around the varistor ontology, the slope for being tilted towards inside is equipped in ceramic jacket,
The ceramic jacket both sides are respectively equipped with electrode, and pin is connected separately on electrode；It is equipped between the pin and electrode of side molten
Disconnected protective device；Insulating protective layer is equipped with outside the ceramic jacket.
The fuse protecting device includes fusible link.
Two buckles that fusible link is clamped are additionally provided on the fuse protecting device；One of them is snapped connection
To electrode, another snaps connection pin, and fusible link is located between two buckles.
Further, insulation board is additionally provided between the buckle and electrode that are connected with pin.
The buckle is U-shaped structure, is in contact, is buckled as spring leaf at the top of U-shaped buckle.
Further, the position that buckle top is in contact is equipped with gap slot corresponding with fusible link.
The utility model is had the advantages that using above-mentioned technical proposal：
Overall structure is simple, and to fusible link using being clamped, fusible link can be in superpressure during ensureing use
In the case of timely fusing realize short-circuit effect, meanwhile, resistor can more easily in the case where fusible link fuses
Recycling is carried out, the waste of resource is reduced.
