Embodiment
A kind of surge protector that comprises the overheated dropout indicating device of overcurrent; Comprise module housing; Be arranged on the module carrier in the module housing; Be fixedly mounted on the overvoltage suppression element on first of the module carrier, also comprise dropout electrode that is positioned at second of module carrier and the overheated dropout linkage of overcurrent that is positioned at module carrier one side, the electrode of wherein threading off is welded on the center of overvoltage suppression element through the soldered material.
The below combines accompanying drawing and specific embodiment that the utility model is done further description.
Embodiment
Fig. 1, Fig. 2 are the structure principle chart of the utility model embodiment product under normal condition.Like figure; Said surge protector comprises module housing 1, is arranged on the module carrier 2 in the module housing 1, is fixedly mounted on the overvoltage suppression element 3 on 2 first of the module carriers; Be chip varistor 3 in the present embodiment; Also comprising the dropout electrode 4 that is positioned at 2 second of module carriers, is dropout copper sheet 4 and the overheated dropout linkage of overcurrent that is positioned at module carrier 2 one sides in the present embodiment.In the present embodiment, the overheated dropout linkage of said overcurrent comprises indicating piece 5 and the flexible member that is connected with indicating piece 5 contacts, and flexible member is a spring 6 in the present embodiment.Indicating piece 5 is movably arranged on the module carrier 2 through locating shaft, and can slide along module carrier 2.Module carrier 2 is provided with location hole, and spring 6 is compressed in the location hole of module carrier 2.One end of dropout copper sheet 4 is welded on the center of the chip varistor 3 that is positioned at 2 first of module carriers, and weld uses the low temperature soldering to connect, and the other end of dropout copper sheet 4 is fixedly mounted in the holddown groove of indicating piece 5.The indicating piece 5 of the surge protector of present embodiment is simultaneously also as the product failure indicating device; The alert flag look is smeared in a non-side that contacts with module carrier 2 on the indicating piece 5; Be red in the present embodiment, constitute product failure alert flag 7, below be called red alert flag 7.Module housing 1 is having transparency window 8 with red alert flag 7 corresponding sides.Indicating piece 5 has a segment distance from the transparency window 8 of module housing 1 under the product normal condition, and this moment, we can't see the red alert flag 7 on the indicating piece 5 through the transparency window on the module housing 18.Be merely for example, during practical implementation, the kind of overvoltage suppression element, dropout electrode, flexible member, welding material, alert flag look also can have a lot of distortion here, and the utility model is not made qualification to this.
Fig. 3, Fig. 4 are the structure principle chart of the utility model embodiment product under the overheating failure state.To such an extent as to when thunder-strike current is excessive when making the temperature of chip varistor 3 rise to the fusing point of low temperature scolding tin, the low temperature scolding tin on the pad of dropout copper sheet 4 and chip varistor 3 fusing rapidly breaks off; Indicating piece 5 is open rapidly under the promotion of spring 6, and dropout copper sheet 4 is pushed away pad under the drive of indicating piece 5, thereby blocks the power frequency continued flow of product.The red alert flag 7 that this moment, the transparency window 8 on the module housing 1 showed on the indicating pieces 5, exhibit red means product failure, thereby loses efficacy indication.
Fig. 5, Fig. 6 are the structure principle chart of the utility model embodiment product under the overcurrent failure state.When the electric current moment that flows to chip varistor 3 was excessive, dropout copper sheet 4 fusing was automatically opened, and indicating piece 5 is open rapidly under the thrust of spring 6, because dropout copper sheet 4 is installed in the holddown groove of indicating piece 5, so also pushed away pad together by spring 6.Pad is in open-circuit condition with outside lead like this, and then has avoided the generation of lightning strike accident, has played the overcurrent protection effect.Red alert flag 7 on transparency window on the module housing 18 demonstration indicating pieces 5 shows that this product lost efficacy, thereby lost efficacy indication at this moment.
The utility model preferred embodiment disclosed herein just is used for helping to set forth the utility model.Preferred embodiment does not have all details of detailed descriptionthe, does not limit this utility model yet and is merely described embodiment.Obviously, according to the content of this specification, can do a lot of modifications and variation.These embodiment are chosen and specifically described to this specification, is principle and practical application in order to explain the utility model better, thereby make one of ordinary skill in the art can utilize the utility model well.The utility model only receives the restriction of claims and four corner and equivalent.
