Abstract
The utility model discloses a kind of low-voltage isolating switch fuse group, include housing, described case top offers mounting groove, wherein, in described mounting groove, be provided with two groups of contacts, in every group of contact, include two metal contact pieces that arrange in opposite directions, described metal contact piece includes conducting portion and wire connecting portion, described conducting portion one end is fixed on described enclosure interior, the other end extends in described outside and offers screwed hole, in described screwed hole, be equipped with the first stud, described wire connecting portion is fixed together by described the first stud and described conducting portion.Owing to being provided with four metal contact pieces, make contact more; Sensitive, thermal diffusivity is better, has improved the security performance of isolating switch fuse group.
Description
Technical field
The utility model relates to a kind of low-voltage isolating switch fuse group.
Background technology
Isolating switch fuse group has another name called fuse group isolating switch, is a kind of multipole, manual operation switch, adopts glass fibre to strengthen unsaturated polyester resin and manufactures shell, has very high dielectric property, protective capacities and reliable processing safety.Operating mechanism is spring energy-storage, the acceleration mechanism of instantaneous relase, momentary connection and disconnection multiple break contact structure.Irrelevant with the speed of operating grip, greatly improved every electric property and mechanical performance.
In prior art, a kind of fuse group with isolating switch is disclosed in the Chinese invention patent prospectus that is 200610096620.5 in the patent No., include isolating switch body and fuse, isolating switch body includes housing, rotating shaft and dynamic and static contact, dynamic and static contact is closed with the rotation of rotating shaft, disconnection coordinates, and fuse includes base and opening, opening is provided with fuse element, between the rotating shaft described in being characterized in and opening, is provided with interlocking device.The present invention utilizes the interlocking device of rotating shaft and opening, only make to rotate to open position and just can open fuse opening in the rotating shaft of isolating switch, thereby can change fuse element, or when opening fuse opening, isolating switch cannot close a floodgate, thereby has guaranteed the safety that fuse uses.
But the isolating switch fuse group of above-mentioned patent, has generally only included two contacts, contact badly, and in when energising, temperature raises very fast, fail safe is bad.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of low-voltage isolating switch fuse group sensitive, that thermal diffusivity good, coefficient of safety is high that contacts.
For achieving the above object, the utility model provides following technical scheme: a kind of low-voltage isolating switch fuse group, include housing, described case top offers mounting groove, wherein, in described mounting groove, be provided with two groups of contacts, in every group of contact, include two metal contact pieces that arrange in opposite directions, described metal contact piece includes conducting portion and wire connecting portion, described conducting portion one end is fixed on described enclosure interior, the other end extends in described outside and offers screwed hole, in described screwed hole, be equipped with the first stud, described wire connecting portion is fixed together by described the first stud and described conducting portion.
As the improvement of above-mentioned low-voltage isolating switch fuse group in the utility model, between the metal contact piece that two arrange in opposite directions, by the second stud, be fixed together.
Further improvement as above-mentioned low-voltage isolating switch fuse group in the utility model, is fixed with arc quenching plate in described wire connecting portion.
Compared with prior art, the utility model has the advantage of: by being provided with four metal contact pieces, than two metal contact pieces of the prior art, contact sensitiveer, thermal diffusivity is good, and the temperature of metal contact piece can too fastly not raise, and has improved coefficient of safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of low-voltage isolating switch fuse group of the utility model.
In figure: 1, housing; 2, mounting groove; 3, metal contact piece; 31, conducting portion; 32, wire connecting portion; 4, screwed hole; 5, the first stud; 6, the second stud; 7, arc quenching plate.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1, the present embodiment is a kind of low-voltage isolating switch fuse group, include housing 1, described case top offers mounting groove 2, wherein, in described mounting groove, be provided with two groups of contacts, in every group of contact, include two metal contact pieces 3 that arrange in opposite directions, described metal contact piece includes conducting portion 31 and wire connecting portion 32, described conducting portion one end is fixed on described enclosure interior, the other end extends in described outside and offers screwed hole 4, in described screwed hole, be equipped with the first stud 5, described wire connecting portion is fixed together by described the first stud and described conducting portion.Between the metal contact piece that two arrange in opposite directions, by the second stud 6, be fixed together.
In described wire connecting portion, be fixed with a plurality of arc quenching plates 7.When wire is connected to metal contact piece, in the moment of connecting, disconnect, can produce a large amount of electric arc, easily initiation fire, arranges arc quenching plate and can eliminate a large amount of electric arc, thereby improved security performance.
The above is only preferred implementation of the present utility model, and protection range of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
