Abstract
The invention discloses an isolating switch with multi-element contacts, which comprises a switch pedestal, a contact bracket, a plurality of movable contact groups, a plurality of leaf springs and a plurality of stationary contacts. The isolating switch with the multi-element contacts provided by the invention is of a multi-contact structure changed from a single-contact structure in the prior art, and contact areas among the movable contacts and the stationary contacts are increased, so that the excessive temperature rise of the contacts is avoided; in addition, as the contact areas among the movable contacts and the stationary contacts are large, each contact can ensure the product has dynamic stability and thermal stability without over-great contact pressure, and is convenient to operate.
Description
Technical field
The invention belongs to the low voltage electrical apparatus technology field, particularly relate to a kind of isolating switch that has multi-element contacts.
Background technology
Isolating switch is a kind of being used for the part that the distribution system needs have a power failure to be isolated with live part reliably; Mostly contact with on the present isolating switch of using always of the electric elements that guarantee service work safety is the single contact structure; Because the contact area on the isolating switch of this structure between moving contact and the fixed contact is little, therefore make contact temperature rise too high easily.In addition, have moving reliably, thermal stability, can only take to increase the method for contact pressure, but excessive contact pressure can increase the operating physical force of product again, thereby bring inconvenience to the user in order to guarantee product.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of temperature rise that can reduce contact, and the good isolating switch that has multi-element contacts of thermal stability.
In order to achieve the above object, the isolating switch that has multi-element contacts provided by the invention comprises switch base, contact supporting, a plurality of moving contact group, a plurality of spring leaf and a plurality of fixed contact; Wherein switch base is made up of two end plates that vertically laterally arrange and a plurality of dividing plates of being set in parallel between two end plates, and the middle part of each end plate is outwards outstanding to be formed with a boss, forms a support in the inside of boss thus and moves the hole; Fixed contact is that knife-edge is tabular; Standoff distance is horizontally installed with two fixed contacts in the space between end plate and adjacent with it dividing plate and two adjacent separator; And the handle of a knife of two fixed contacts inwardly and be symmetrical set, and the handle of a knife on all fixed contacts is positioned at the same side; Contact supporting is rectangular box-like, separated by a distance caving inward and be formed with a plurality of moving contact installing holes on the inner surface on each long limit on it, and two supports that two minor faces are vertically set on two end plates move in the hole; One group of moving contact group 3 of being made up of the multi-disc moving contact is installed in each moving contact installing hole; The top, both sides of each moving contact installing hole links to each other with the upper end of a spring leaf respectively, and the bottom of each spring leaf then contacts the surperficial outer end one group of moving contact group.
A plurality of moving contact position of mounting hole on described two long limits that are positioned at contact supporting are corresponding each other, and the distance between the adjacent moving contact installing hole equates.
Described moving contact group lower surface and the surface of fixed contact that is installed on the long limit that is positioned at upside on the contact supporting is positioned at sustained height.
Described moving contact group upper surface and the bottom surface of fixed contact that is installed on the long limit that is positioned at downside on the contact supporting is positioned at sustained height.
Distance between described end plate and adjacent with it dividing plate and two adjacent separator equates.
The quantity of described moving contact group is the half the of fixed contact quantity.
The isolating switch that has multi-element contacts provided by the invention is that the single contact structure with prior art makes the multiconductor structure into, owing to increased the contact area between moving contact and the fixed contact, therefore is difficult for causing contact temperature rise too high.In addition, because the contact area between moving contact and the fixed contact is big, so each contact need not excessive contact pressure and just can guarantee that product has moving reliably, thermal stability, and is convenient to operate.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the isolating switch that has multi-element contacts provided by the invention is elaborated.
Like Fig. 1-shown in Figure 4, the isolating switch that has multi-element contacts provided by the invention comprises switch base 1, contact supporting 2, a plurality of moving contact group 3, a plurality of spring leaf 4 and a plurality of fixed contact 5; Wherein switch base 1 is made up of two end plates that vertically laterally arrange 6 and a plurality of dividing plates 7 of being set in parallel between two end plates 6; The middle part of each end plate 6 is outwards given prominence to and is formed with a boss 10, forms a support in the inside of boss 10 thus and moves hole 11; Fixed contact 5 is that knife-edge is tabular; Standoff distance is horizontally installed with two fixed contacts 5 in the space between end plate 6 and adjacent with it dividing plate 7 and two adjacent separator 7; And the handle of a knife of two fixed contacts 5 inwardly and be symmetrical set, and the handle of a knife on all fixed contacts 5 is positioned at the same side; Contact supporting 2 is rectangular box-like, separated by a distance caving inward and be formed with two supports that 9, two minor faces of a plurality of moving contact installing holes are vertically set on two end plates 6 and move in the hole 11 on the inner surface on each long limit on it; One group of moving contact group 3 of being made up of the multi-disc moving contact is installed in each moving contact installing hole 9; The top, both sides of each moving contact installing hole 9 links to each other with the upper end of a spring leaf 4 respectively, and the bottom of each spring leaf 4 then contacts the surperficial outer end one group of moving contact group 3.
A plurality of moving contact installing holes 9 positions on described two long limits that are positioned at contact supporting 2 are corresponding each other, and the distance between the adjacent moving contact installing hole 9 equates.
Described moving contact group 3 lower surfaces and the surface of fixed contact 5 that is installed on the long limit that is positioned at upside on the contact supporting 2 is positioned at sustained height.
Described moving contact group 3 upper surfaces and the bottom surface of fixed contact 5 that is installed on the long limit that is positioned at downside on the contact supporting 2 is positioned at sustained height.
Distance between described end plate 6 and adjacent with it dividing plate 7 and two adjacent separator 7 equates.
The quantity of described moving contact group 3 is the half the of fixed contact 5 quantity.
When the isolating switch that has multi-element contacts provided by the invention is in gate-dividing state; As shown in Figure 3; A plurality of moving contact groups 3 on the contact supporting 2 are in the position away from fixed contact 5, and at this moment, the support that a side minor face of contact supporting 2 is on the end plate 6 that is positioned at the same side with it moves hole 11.When needs close a floodgate; At first contact supporting 2 is applied the operating physical force of horizontal direction by operating personnel; Under power effect in addition; Contact supporting 2 will drive a plurality of moving contact groups 3 mounted thereto together along continuous straight runs move towards opposite side end plate 6 directions; The support that is on the end plate 6 that is positioned at the same side with it until the opposite side minor face of contact supporting 2 moves hole 11, and at this moment the two ends of each moving contact group 3 will contact respectively on the handle of a knife surface that is positioned at two fixed contacts 5 of same group, thereby with moving contact group 3 and fixed contact 5 closures.
