Description
Technical field
This utility model relates to disconnecting switch technical field, particularly to a kind of outdoor drop-out fuse be used for fix
The assembly of touch spring.
Background technology
Outdoor drop-out fuse is the high-tension switch gear in electrical network power transmission and transforming equipment, is that in power system usage amount is
Greatly, product that range of application is the widest, outdoor high-voltage protection electrically, has to fall and cut-offs function.It is that specialty replacement old type tube falls
The advanced product of formula fuse, be suitable for wind energy turbine set, oil, chemical industry, iron and steel, power station as protection segmentation essential product, it
It is assemblied on distribution transformer high-pressure side or distribution wire branch circuit, makees transmission line of electricity, power transformer overload and short-circuit protection
And a deciliter rated load current is used.Have simple to operate, easy to maintenance.Effectively solve fault-free to fall.
Making outdoor drop-out fuse problem the most for various reasons, touch spring is again fuse switch equipment
Key component, bad easily goes wrong as fixing, present stage, outdoor drop-out fuse fixed contact spring mode by rain cover and
Bore a hole rivet on contact tabletting to connect fixed contact spring, contact tabletting, rain cover by rivet contact tabletting, rain cover
Between play fixed contact spring, touch spring is difficult to owing to rivet reason is fixed change, touch spring and easily sliding, rivet
Head reason causes moving contact brastil nut and contact tabletting loose contact.
In order to solve this problem, hereby, this utility model is proposed.
Summary of the invention
The purpose of this utility model, is to provide the group for fixed contact spring of a kind of outdoor drop-out fuse
Part.
In order to realize these purposes, adopt the following technical scheme that
The assembly for fixed contact spring of a kind of outdoor drop-out fuse, including rain cover 1, contact tabletting 2；
Rain cover 1 is surrounded by side 11 and end face 10；
Two sides 11 are parallel to each other, and two sides 11 are connected with end face 10 respectively；Whole rain cover 1 is in matrix；
Contact tabletting 2 is divided into connecting portion 24, supporting part 23, stop part 22,21 4 parts of contact part；These four part groups
Be combined into that lower end is narrow, that upper end is wide is trapezoidal；
Described rain cover 1 and contact tabletting 2 are formed and accommodate space 5.
The first installing hole 13 and the second installing hole 14 it is provided with on described rain cover 1.
Described rain cover 1 is by stainless steel substrates punch forming.
Described contact tabletting 2 is stamping forming by latten(-tin).
Beneficial effect:
Rain cover described in the utility model and contact tabletting form receiving space and are used for fixed contact spring, make contact bullet
Spring does not has rivet to limit, and assembles more convenient, and contact nut contacts more preferably with contact tabletting.
Accompanying drawing explanation
Fig. 1 is this utility model side structure schematic diagram.
Fig. 2 is this utility model axonometric chart.
Fig. 3 is that this utility model uses view.
The following is the mark of accompanying drawing in this utility model, illustrated by accompanying drawing and corresponding mark, can be clearly understood from
This utility model.
Rain cover 1, contact tabletting 2, touch spring 3, contact nut 4, accommodate space 5, end face 10, side 11, excessive face
12, the first installing hole 13, the second installing hole 14, contact part 21, stop part 22, supporting part 23, connecting portion 24
Detailed description of the invention
With reference to Fig. 1-3,
The assembly for fixed contact spring of a kind of outdoor drop-out fuse, including rain cover 1, contact tabletting 2.Anti-
Canopy 1 is surrounded by side 11 and end face 10.Two sides 11 are parallel to each other, and two sides 11 are connected with end face 10 respectively
Connect.The excessive face 12 of inclination it is provided with between side 11 and end face 10.Angle between side 11 and end face 10 is right angle, excessive face
The angle of 12 acute angles formed with end face 10 with side 11 respectively is 45.Whole rain cover 1 is in matrix.
The first installing hole 13 and the second installing hole 14 it is provided with on rain cover 1.
Rain cover 1 is by stainless steel substrates punch forming.
Described contact tabletting 2 is stamping forming by latten(-tin), and whole contact tabletting 2 is divided into connecting portion 24, supporting part 23,
Stop part 22,21 4 parts of contact part；It is trapezoidal that these four parts are combined as that lower end is narrow, upper end is wide.
Contact tabletting 2 punch forming rear surface is silver-plated.
Connecting portion 24 is connected with one end of supporting part 23, the angle that connecting portion 24 is less with the number of degrees of supporting part 23 formation
For obtuse angle, the angle of angle is 135 degree.
Stop part 22 is connected with the other end of supporting part 23, the folder that stop part 22 is less with the number of degrees of supporting part 23 formation
Angle is obtuse angle, and the angle of angle is 135 degree.
The other end of stop part 22 is connected with contact part 21.
Rain cover 1 and contact tabletting 2 are formed and accommodate space 5.
With reference to Fig. 3, during use, touch spring 3 is placed in receiving space 5, is positioned at supporting part 23 and accommodates the one of space 5
Side supports touch spring 3, and the opposite side of supporting part 23 contacts with contact nut 4, and side 11 and contact tabletting 2 can keep off
Touch spring 3, prevents touch spring 3 from skidding off from receiving space 5.
This utility model can be fixed on insulating part by the first installing hole 13 and the second installing hole 14.
Although being disclosed this utility model by above example, but protection domain of the present utility model does not limit
In this, the equivalent under the conditions of conceiving without departing from this utility model broadly falls into protection domain of the present utility model.
