Abstract
The utility model relates to a composite insulation fall-type fuse. The utility model is characterized in that the structure of an insulating support member is that an apron cover of the synthetic insulating material is sheathed on a core rod adopted with composite insulating materials. A fastening device which is used for fixing an upper fixed contact and a lower fixed contact is also installed on both ends of the core rod. The utility model has the advantages of easy fabrication, light product weight self, and small volume. In the processes of production and use, the utility model has no breakage. In addition, the utility model has good antifouling property and high mechanical strength.
Description
The utility model relates to a kind of compound inslation fuse switch.
In the known technology, the structure of insulated support is exactly the electroceramics porcelain vase in the fuse switch, and its fuse is by electroceramics porcelain vase, upper and lower fixed contact, fuse, cartridge fuse and upper and lower movable contact is first-class forms.Wherein upper and lower fixed contact is to fix at the bolt at electroceramics porcelain vase two ends or the clip that is looped around electroceramics porcelain vase two ends by mucilage binding, this kind structure exist the production cycle long, manufacturing process is complicated, product weight is big, produce and use in damaged easily, in addition, antifouling property is poor, and mechanical strength is subjected to material to influence also big or the like deficiency.
The purpose of this utility model is to overcome the deficiency of known technology, and provide a kind of with short production cycle, manufacturing process is simple, volume is little, do not have the fuse switch of the novel insulated support of employing damaged, that antifouling property is good and mechanical strength is high in light weight, production and the use.
The purpose of this utility model is achieved in that
The structure of the insulated support in the utility model is the skirt cover that is set with synthetic insulating material on the plug of composite insulating material selecting for use, and the fastener that is used for fixing upper static contact, following fixed contact and supporting bracket also is housed at the two ends of plug.
The fastener that install at plug two ends in the insulated support can be equipped with bolt for respectively having in the plug both ends of the surface on the screwed hole; Also can be for the clip that has bolt that is surrounded on plug respectively is installed at the plug two ends; Can also be on the through hole that respectively has at the plug two ends bolt being installed perpendicular to the plug axis.
Insulated support structure in the utility model is because what adopt is to be set with the skirt cover of selecting synthetic insulating material for use on the plug of composite insulating material selecting for use, in addition, fastener also is equipped with at two ends at plug, the advantage that then shows is: make simple, product itself is in light weight, volume is also little, does not have damaged in production and use; In addition, antifouling property is good and the mechanical strength height.
The utility model has following accompanying drawing:
Fig. 1 is the utility model structural representation;
Fig. 2 is second kind of structural representation of insulated support in the utility model;
Fig. 3 is the third structural representation of insulated support in the utility model.
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
Embodiment one: as shown in Figure 1, what the structure of insulated support adopted is, selecting composite insulating material for use, be set with on the plug 2 as the epoxy glass fabric rod and select synthetic insulating material for use, skirt cover 1 as silicon rubber, on the bolt hole 4 that the plug both ends of the surface respectively have, bolt 3 is installed, be equipped with by bolt 3, following fixed contact 5,6 and supporting bracket 11, on cartridge fuse 15, install in addition, lower moving contact 12,13 and fuse 14, the axle 16 that falls by lower moving contact is mounted on the supporting bracket 11, go up moving contact 12 by upper static contact cap 17 chuckings again, make upper static contact, last moving contact, following fixed contact, lower moving contact is in closure state.
Embodiment two: as shown in Figure 2, with the difference of embodiment one just, the clip that has bolt 87 that is surrounded on plug respectively is being installed by the plug two ends.Again by clip chucking upper static contact 5 and the supporting bracket 11 that is connected as a single entity with following fixed contact 6.
Embodiment three: as shown in Figure 3, with the difference of embodiment one just, respectively have through hole 9 perpendicular to the plug axis at the plug two ends, be installed on the through hole 9 with upper static contact 5 with supporting bracket 11 that following fixed contact 6 is connected as a single entity by bolt 10.
Claims (2)
1, a kind of compound inslation fuse switch, form by insulated support, upper static contact, time fixed contact, supporting bracket, fuse, cartridge fuse, last moving contact, lower moving contact, it is characterized in that: the structure of insulated support is to be with the skirt cover 1 of selecting synthetic insulating material for use on the plug 2 of selecting composite insulating material for use, and the fastener that is used for fixing upper static contact 5 and following fixed contact 6 and supporting bracket 11 also is housed at the two ends of plug.
2, compound inslation fuse switch according to claim 1 is characterized in that: the fastener that install at the plug two ends can be equipped with bolt 3 for respectively having in the plug both ends of the surface on the screwed hole 4; Also can be for the clip that has bolt 87 that is surrounded on plug respectively is installed at the plug two ends; Can also be on the through hole 9 that respectively has at the plug two ends bolt 10 being installed perpendicular to the plug axis.
