Description
Technical field
The utility model relates to a kind of switch, especially a kind of outdoor low voltage fuse cutout.
Background technology
Existing outdoor low voltage fuse cutout is an integral type, and promptly three groups of moving contact seats and static contact seat are installed on the same base, and contacting between fixed contact and the moving contact adopts spring to clamp, and the two ends of fuse link are separately fixed on fixed contact and the moving contact.The switch of this structure in use has the following disadvantages: 1, because the dynamic and static touch base of its many groups is fixed on the same base, as long as damaged wherein one, just must will puts in order the group switch and all change, cause great waste; 2, the contact between the dynamic and static contact is clamped with spring, when deciliter often after add corrosion, thereby the elasticity of spring reduces and to cause switch to be burnt out because of dynamic and static contact loose contact; 3, the two ends of fuse link are separately fixed on the dynamic and static contact, be not easy to change, and if change the back and regulate badly, contact is loosening easily, causes dynamic and static contact loose contact, makes switch be easy to be burnt out; 4, dynamic and static contact adopts the copper coin riveted joint to form, and after the riveted joint, the riveted joint of rivet and contact is flat inadequately, can make dynamic and static contact loose contact, resistance excessive, is easy to burn out; 5, upper and lower moving contact is to adopt the porcelain bar to be connected and fixed, and under the outdoor high temperature weather condition, adds that the heat that porcelain bar itself produces can make the contact electric current strengthen, and causes the fracture of porcelain bar, can not satisfy the electric power requirement.
Summary of the invention
The contact that the purpose of this utility model just provides between a kind of dynamic and static contact can be adjusted, and fastness height, fuse link are changed outdoor low voltage fuse cutout easily.
Solution of the present utility model is such: include base, be installed in static contact seat and moving contact seat on the base, and fuse link, on described moving contact seat, be hinged with blade, an end of this blade when switch closure and static contact seat join; One end of described fuse link is fixed on the moving contact seat, and the other end is connected with connecting plate on being fixedly mounted on base.
In such scheme, the centre of described blade can have groove, and an end of this groove is enclosed within the both sides of moving contact seat, the other end when switch closure and the both sides end face of static contact seat join; The bolt that external diameter is set with compression spring can be equipped with in two ends at the groove of described blade, and an end of compression spring withstands blade, and the other end withstands bolt; Described static contact seat, moving contact seat and connecting plate can be to be installed on the post insulator respectively; Described static contact seat and moving contact seat can be to cast with red copper to form, and can be provided with one deck silver coating in its appearance; Described blade can be to adopt red copper to make, and its appearance can be provided with one deck silver coating.
The utility model has the advantages that: 1, there is the blade of groove hinged centre on moving contact seat, and the bolt that external diameter is set with the compression spring that withstands blade is installed at the two ends of groove, make its closure be adjacent to static contact seat when switch can compress blade in folding by the adjusting bolt when repeatedly the contact between the dynamic and static touch base in back is loosening, make contact more solid and reliable.2, fuse link is fixed between moving contact seat and the connecting plate, is more convenient for changing, and does not need to regulate the fastness that more can not influence contact.3, static contact seat, moving contact seat and connecting plate all are to be installed in post insulator respectively, can change respectively during damage, avoid causing unnecessary waste.4, dynamic and static touch base all is to cast with red copper to form, and its contact and touch base are connected as a single entity, and do not need other riveted joint, and establish silver coating in its appearance, make resistance decreasing, and contact-making surface is good, is not easy to burn out.4, the blade that connects dynamic and static touch base adopts red copper to make, and silver-plated in its appearance, because red copper conducts electricity very well, the electric current that passes through is diminished be difficult for burning out.
Description of drawings
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is vertical views of accompanying drawing 1.
Embodiment
Present embodiment includes base 1, post insulator 2, static contact seat 3, compression spring 4, deciliter draw ring 5, blade 6, banking stop 7, fuse link 8, gusset piece 9, moving contact seat 10, bowl-type rubber pad 11, bolt 12, carbon brush 13.
On described moving contact seat 10, be hinged with blade 6, an end of this blade 6 when switch closure and static contact seat 3 join; One end of described fuse link 8 is fixed on the moving contact seat 10, and the other end is connected with connecting plate 9 on being fixedly mounted on base 1.
There is groove the centre of described blade 6, and an end of this groove is enclosed within the both sides of moving contact seat 10, the other end when switch closure and the both sides end face of static contact seat 3 join.
The bolt 12 that external diameter is set with compression spring 4 is equipped with at two ends at the groove of described blade 6, and an end of compression spring 4 withstands blade 6, and the other end withstands bolt 12.
