The upper end of the sheath is fixed in the lower end of the lower insulation sleeve, and the upper end elasticity of the spring is installed in the moving contacting plate
On downside, the lower end elasticity of the spring is installed on the medial surface of the lower insulation sleeve；The lower end of the upper insulation sleeve to
Under extend in the lower insulation sleeve.
The sheath is the truncated cone-shaped that upper side is small, downside is big as a further improvement of the utility model, under described
The lower end of insulation sleeve is equipped with positioning step, and the lower insulation sleeve is fixed on the upper side of the sheath by the positioning step
It is interior.
As a further improvement of the utility model, the upper end of the upper insulation sleeve by circlip and metal gasket with it is described
The upper end of metal shaft is fixedly connected.
The upper end of the upper insulation sleeve extends outward to form top bar as a further improvement of the utility model, described

Suffer from and occurring, more securely and reliably.Meanwhile sheath and insulation sleeve and spring structure can further function as buffer function, reduction is made an uproar
Sound and abrasion improve contactor service life.
Detailed description of the invention
Fig. 1 is the utility model schematic perspective view；
Fig. 2 is the utility model section structural schematic diagram.
In conjunction with attached drawing, make the following instructions:
1 --- magnetic conductive board component；2 --- metal shaft；
3 --- upper insulation sleeve；4 --- moving contacting plate；
5 --- spring；6 --- lower insulation sleeve；
7 --- sheath；8 --- circlip；
9 --- metal gasket；31 --- top bar.
Specific embodiment
Below in conjunction with attached drawing, elaborate to a preferred embodiment of the utility model.But the guarantor of the utility model
Shield range is not limited to following embodiments, i.e., in every case with simple made by present utility model application the scope of the patents and description
Equivalent changes and modifications all still belong within the utility model patent covering scope.
It is a kind of D.C. contactor movable contact assembling structure described in the utility model, including magnetic conductive board refering to attached drawing 1-2
Component 1 and lower end activity are assemblied in the metal shaft 2 on the magnetic conductive board component, and the upper end fixed sleeves of metal shaft are equipped with upper insulation
4 fixing sleeve of moving contacting plate of set 3, D.C. contactor is set to outside the upper insulation sleeve；It is successively arranged outside the lower end of the metal shaft
There are spring 5, lower insulation sleeve 6 and sheath 7, the lower end of the sheath is fixed on the magnetic conductive board component, the lower insulation sleeve
The upper end of the sheath is fixed in lower end, and the upper end elasticity of the spring is installed on the downside of the moving contacting plate, described
The lower end elasticity of spring is installed on the medial surface of the lower insulation sleeve；The lower end of the upper insulation sleeve extend downward into it is described under
In insulation sleeve.
Wherein, the sheath is the truncated cone-shaped that upper side is small, downside is big, and the lower end of the lower insulation sleeve is equipped with positioning table
Rank, the lower insulation sleeve are fixed in the upper side of the sheath by the positioning step；The upper end of the upper insulation sleeve is logical
It crosses circlip 8 and metal gasket 9 is fixedly connected with the upper end of the metal shaft；The upper end of the upper insulation sleeve extends outward to form
Top bar 31, the upper side of the moving contacting plate are installed in the top bar；The lower insulation sleeve is plastic part, the sheath
It is made of elastic material.
Metal shaft is first assembled on magnetic conductive board component, then by the D.C. contactor movable contact assembling structure in assembly
Successively by sheath, lower insulation sleeve, spring, moving contacting plate, upper golden insulation sleeve, metal gasket assembly in metal shaft, finally with card
Above-mentioned parts are fixed in metal shaft by spring, form a kind of D.C. contactor movable contact assembling structure as described in Fig. 1-2.It should
Assembling structure is not since moving contacting plate is to be fit directly into metal shaft, and be fixed in metal shaft by upper insulation sleeve, i.e.,
It is insulated between moving contacting plate and metal shaft by upper insulation sleeve, while spring is set on insulation sleeve, and lower spring end supports
