Description
Technical field
The utility model relates to a kind of disconnecting switch moving contacts, belong to disconnecting switch technical field.
Background technique
Disconnecting switch should be able to bear normal load current when operating normally, and of short duration failure can be born in failure
Electric current.Since electric current has fuel factor, when disconnecting switch conducting position poor contact, poor contact position resistance increases, electricity
Stream fuel factor also increases with it, meeting scaling loss disconnecting switch when thermal energy accumulation is serious, and existing disconnecting switch includes spill
Two rotatable clamping pieces are usually arranged in moving contact and static contact with convex, the moving contact of spill, rotate in clamping piece front end
Tail end is remained during clamping static contact contacts with moving contact rack body, but contact area is because of the change of rotary course
To change, effective contact area becomes smaller, and cause the conducting position poor contact good, thus be easy to burn out disconnecting switch.
Summary of the invention
Technical problem to be solved by the utility model is: a kind of disconnecting switch moving contact is provided, to solve the prior art
The problem of.
The technical solution that the utility model is taken are as follows: a kind of disconnecting switch moving contact, two including front and back asymmetric conduction
Clamping piece, support body and extension spring, two clamping pieces are connected on support body by the extension spring being located on support body,
The hook at extension spring both ends is articulated in gag lever post after being each passed through two clamping pieces, and gag lever post is resisted against on the outside of clamping piece, clamping
Piece can be rotated around gag lever post, and support body right end is provided with conductive cantilever lever, passed through annealed copper wire one on the outside of clamping piece and be connected to conduction
Cantilever lever.
Preferably, it is resisted against support body one end when above-mentioned two clamping piece rotates and is provided with positive stop lug boss, corresponding positive stop lug boss
Shrinkage pool is provided on the support body of position.
Preferably, the clamping piece of above-mentioned every side uses two panels conductive sheet side by side, and annealed copper wire two is connected between two panels conductive sheet.
Preferably, above-mentioned support body includes U-shaped board and groove-like box, and U-shaped board open at one end is clamped in groove-like box
Opening direction on and adopt and be tightened by bolts, and U-shaped board bottom and the end face of groove-like box is kept to keep gap.
The utility model has the beneficial effects that compared with prior art, clamping piece and cantilever of the utility model in moving contact
It installs conductive annealed copper wire one between bar additional, improves the current overload ability of moving contact, effectively avoid existing clamping piece tail end conductive
The problem of fever caused by location contacts are bad burns out disconnecting switch, improves the service life of disconnecting switch, the utility model is also
Have the characteristics that structure is simple, at low cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the overlooking structure diagram of the utility model.
Specific embodiment
With reference to the accompanying drawing and the utility model is described further in specific embodiment.
Embodiment: as Figure 1-Figure 2, a kind of disconnecting switch moving contact, two clamping pieces including front and back asymmetric conduction
1, conductive support body 2 and extension spring 3, two clamping pieces 1 are connected by the extension spring 3 being located on support body 2 and are being propped up
On frame body 2, the hook at 3 both ends of extension spring is articulated in gag lever post 4 after being each passed through two clamping pieces 1, and gag lever post 4 is resisted against clamping
1 outside of piece, clamping piece 1 can be rotated around gag lever post 4, and 2 right end of support body is provided with conductive cantilever lever 5, be passed through on the outside of clamping piece 1 soft
Copper wire 1 is connected to conductive cantilever lever 5, and one 6 both ends of annealed copper wire are connected to clamping piece 1 and conductive cantilever lever 5 by welding manner
On.
Preferably, it is resisted against 2 one end of support body when above-mentioned two clamping piece 1 rotates and is provided with positive stop lug boss 7, corresponding limit convex
It is provided with shrinkage pool 8 on the support body 2 of 7 position of platform, which improves the connection reliability in clamping piece rotary course.
Preferably, the clamping piece 1 of above-mentioned every side uses two panels conductive sheet side by side, and annealed copper wire two is connected between two panels conductive sheet
9,29 both ends of annealed copper wire are connected on two panels conductive sheet by welding manner, improve clamping piece using two panels conducting strip structure
Clamping stability and reliability increase clamping contact face, it is ensured that the current overload ability of disconnecting switch is subtracted using annealed copper wire two
The arrangement of few annealed copper wire one, structure simplify.
Preferably, above-mentioned support body 2 includes U-shaped board 10 and groove-like box 11, and 10 open at one end of U-shaped board is clamped in groove
It is locked on the opening direction of shape box 11 and using bolt 12, and 10 bottom of U-shaped board and the end face of groove-like box 11 is kept to protect
Gap is held, gap is convenient for drawstring spring passing through support body, and the support body structure is simple, and rigidity of support and intensity are high, and support is steady
Qualitative and good reliability.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replacement, it should be covered within the scope of the utility model, therefore, the protection scope of the utility model should be with the power
Subject to the protection scope that benefit requires.
