Abstract
The utility model provides a grounding static contact of an isolating switch. The grounding static contact comprises a grounding rod, wherein contact fingers are respectively fixed at both sides of the grounding rod through fixing screw bolts, and spring strips are respectively fixed at the outer sides of the two contact fingers through fixing screw bolts. The contact fingers are petal-shaped red copper rows folded outwards and are arranged symmetrically; and the spring strips are hand-like and are arranged symmetrically. The grounding static contact provided by the utility model occupies a small space and is compact structure. When the isolating switch is grounded, a moving contact is arranged between the two contact fingers, and the spring strips play a pressing role so as to ensure a large contact area between the static contact and the moving contact to realize good contact performance and good liquidity. The two petal-shaped contact fingers of the static contact and the two hand-like spring strips on the outer side of the contact fingers can ensure the full contact between the moving contact and the static contact of the isolating switch when the isolating switch is grounded; and the two screws also has the guide effect to prevent dislocation of the two contact fingers while playing the fixing effect.
Description
Technical field
The utility model relates to a kind of isolating switch ground connection fixed contact, is specially adapted to isolating switch, earthing isolator.
Background technology
Isolation in the market, the static contact structure complex forms of earthed switch, loaded down with trivial details, the assembling procedure trouble of part, the structural flow general character is bad, when causing switch motion; Moving and fixed contact contact pressure reduces, and contact area reduces, and causes contact resistance to increase; Heating easily in practical application; The long-term use is prone to cause heat ageing, and then makes contact condition further aging, will cause faults such as heating scaling loss when serious.
Summary of the invention
The purpose of the utility model provides a kind of isolating switch ground connection fixed contact, and existing fixed contact complex forms, part are loaded down with trivial details in order to solve, assembling trouble, the bad problem of the structural flow general character.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts provides a kind of isolating switch ground connection fixed contact; Include earth brace, the both sides of earth brace are fixed with fingertip respectively through fixed bolt, and the outside of two fingertips is fixed with spring leaf through set bolt respectively.
Said fingertip is to the petal red copper row of turning up, and is symmetrical set, and said spring leaf is a hand shape, and is symmetrical set.
It is little that the effect of the utility model is to use this ground connection fixed contact to take up room, compact conformation.During ground connection, moving contact is between two fingertips, and this moment, spring leaf played pressuring action, guarantees that like this contact-making surface between moving and the fixed contact is big, and contact performance is good, circulation is good.The spring leaf of two lobe fingertips of this fixed contact and two hand shapes in the outside can guarantee the moving contact and the fixed contact full contact of isolating switch when ground connection; Two screw rods also play guide effect playing fixing effect simultaneously, prevent two fingertip dislocation.
Description of drawings
Fig. 1 is that the utility model is a kind of axis side view of novel isolating switch ground connection fixed contact.
Among the figure:
1, earth brace 2, fixed bolt 3, set bolt 4, spring leaf 5, fingertip
Embodiment
Below in conjunction with accompanying drawing and implement the isolating switch ground connection static contact structure of the utility model is further specified.
The isolating switch ground connection static contact structure of the utility model is, said ground connection fixed contact includes earth brace 1, and the both sides of earth brace 1 are fixed with spring leaf 4 through set bolt 3 respectively through the outside that fixed bolt 2 is fixed with fingertip 5, two fingertips 5 respectively.Sheet is oppositely arranged petal red copper row 5, two of fingertips and is oppositely arranged hand shape, assembles spring leaf and fingertip through fixed bolt, can fix with earth brace through bolt.
Said fingertip 5 is to the petal red copper row of turning up, and is symmetrical set, and said spring leaf 4 is a hand shape, and is symmetrical set.
As shown in Figure 1,2 two fingertips 5 of four double-screw bolts are fixed on the both sides of earth brace 1, and set bolt 3 is assembled spring leaf 4 and two fingertips 5.During ground connection, moving contact is between two fingertips 5, and this moment, spring leaf 4 played pressuring action, guarantees that like this contact-making surface between moving and the fixed contact is big, and contact is good, circulation is good.
