Abstract
The utility model discloses a fuse protector used as a safety protection element for an electric appliance, and particularly relates to a high-temperature-resistant reusable fuse protector. The high-temperature-resistant reusable fuse protector comprises an insulated shell and a fuse arranged in the insulated shell, wherein a fixing groove for fixing the fuse is arranged in the insulated shell; the fuse is a reusable temperature fuse; and a shape memory alloy spring is arranged in the reusable temperature fuse. By using the reusable temperature fuse to replace the original disposable fuse and fixedly mounting the reusable temperature fuse in the insulated shell, the utility model ensures that the service life is longer, the insulativity is better and the high temperature resistance is higher; and the fuse is of a reusable structure, and can increase of the use rate of the fuse protector and reduce the breakdown maintenance rate of the electric appliance, thereby saving more maintenance manpower resources and maintenance cost.
Description
Technical field
The utility model relates to the fuse of electrical equipment protection component safe in utilization, is specifically related to a kind of high-temperature resistant anti renaturation fuse.
Background technology
Traditional temperature fuse by insulation shell, two leading-in conductors and with said two leading-in conductors mutually the fusible metal alloy fuse of welding constitute; It is with a kind of safe accessory that fuse uses, and is the security incidents such as fire that prevent that the unexpected occurrence cause of life household electrical appliances is not clear, and the effect of this accessory is when surpassing the above heating of specific temperature, and the effect of fusible metal alloy fuse can be played open-circuit line to prevent security incident such as fire; Fuse is applicable in the product the inside of heating almost, comprises in household electrical appliances, the electrical equipment and automobile etc., hair-dryer for example, refrigerator; Microwave oven, electric cooker, washing machine; TV, baking oven, electric stove; Transformer, photocopier, charger etc.When traditional fuse was elevated to the particular job temperature in temperature, the fusible metal alloy fuse can directly receive thermal cut, to reach the effect of cutoff circuit; But the fuse defective that can exist is exactly must scrap after the fuse work fusing like this; And then the product that more renews, so can increase and change the human resources and the operating time of fuse, and can cause a kind of waste of material; Also to increase simultaneously the input expense of new fuse; Therefore, to above defective, must a kind of repeatedly used fuse of invention.
The utility model content
The purpose of the utility model is to solve above defective, and a kind of advantages of small volume is provided, and is simple in structure, but has the high temperature resistant high-temperature resistant anti renaturation fuse that uses with the repeatability of insulating effect simultaneously.
The purpose of the utility model realizes in the following manner:
A kind of high-temperature resistant anti renaturation fuse; Comprise insulation shell and be arranged on the inner fuse of insulation shell; Said fuse two ends are provided with intercell connector, and said fuse two ends intercell connector is connected with two leads, is filled with the epoxy resin that is used for fixing fuse and lead in the said insulation shell; Also be provided with the holddown groove that is used to place fuse in the said insulation shell; Said fuse two end interfaces are erect outward and are placed in the holddown groove, and said fuse is the repeatability Thermal Cutoffs, and said repeatability Thermal Cutoffs set inside has shape memory alloy spring.
As preferably, said insulation shell is set to column structure or rectangular structure, and said column structure insulation shell is processed by ceramic material, and said rectangular structure insulation shell is processed by plastic cement material.
As preferably, said two leads are set to high temperature resistant wire, and an other end of said two leads all is provided with connector.
As preferably, said repeatability Thermal Cutoffs outside is made up of metal shell.
The beneficial effect that the utility model produced is: adopt the repeatability Thermal Cutoffs to replace original disposable fuse, and combine insulation shell to be fixed in the insulation shell, make it anti-aging better; Longer service life, insulating properties is better, and is high temperature resistant stronger; Fuse is repeatedly a utilization structure simultaneously, can increase the utilization rate of fuse, makes the product scope of application more extensive; Do not influence the operate as normal of electrical equipment when using repeatedly; Can play the better protection effect, and reduce the apparatus failure maintenance rate, save more maintenance manpower resource and maintenance cost.
