The arc-shaped transition in joint of terminal and the second bending part starting point, side and connected piece phase of the joint close to connected piece
It contradicts.
Preferably, section of the flanging 4 in 5 axial direction of through-hole is arc-shaped.
Embodiment two
As shown in Figs 1-4, the difference of the present embodiment and above-described embodiment one is, the inner edge of ontology 2 is towards outer rim bending side
There is a spacing in 5 axial direction of through-hole close to the side of connector to supporting part 3,3 end of supporting part and flanging 4 is bent to form
From when 4 side of flanging being made to be in contact with connected piece, with gap between 3 end of supporting part and connected piece.
The utility model is by setting supporting part 3, the space interior for surrounding connector depression in supporting part 3, it is therefore prevented that
Connector is loosened by unexpected external force.
Arc-shaped transition between supporting part 3 and support portion 1.3 end of supporting part and flanging 4 exist close to the side of connected piece
Distance in 5 axial direction of through-hole is less than 4 end of flanging with flanging 4 at a distance from the side of connected piece is in 5 axial direction of through-hole.
Supporting part 3 is the inverted cone shape gradually shunk towards connected piece direction.Flanging 4 close to connected piece side and connected
When fitting is pressed against each other and flexible deformation occurs, 3 end of supporting part is exactly in contact with connected piece.
The utility model is by being pressed against each other flanging 4 close to the side of connected piece and connected piece and flexible deformation occurring
When, 3 end of supporting part is exactly in contact with connected piece, on the basis of avoiding the Indentation Damage of connected piece, improves washer
Stability.
Embodiment three
As shown in figure 3, the difference of the present embodiment and above-described embodiment one, two is that flanging 4 is close to the side of connected piece
Including being made of elastic portion 6 elastic material, elastic portion 6 and connected piece are inconsistent.
The utility model further increases the contact area of washer and connected piece by setting elastic portion 6, thus into
One step reduces washer under the pressure effect of connector to the Indentation Damage of connected piece.
Elastic portion 6 is the ring-type extended around 5 axis of through-hole, alternatively, elastic portion 6 is around 5 axis arranged for interval of through-hole
It is multiple.
Example IV
As shown in figure 3, the difference of the present embodiment and above-described embodiment one to three is, elastic portion 6 and flanging 4 are mutually solely
Vertical component, elastic portion 6 are fixed on flanging 4 close to the side of connected piece, elastic portion 6 are made to constitute flanging 4 close to connected piece
Side.
Preferably, elastic portion 6 is made of rubber material.
The inner edge of elastic portion 6 and outer rim extend outside respectively and wrap up side of the flanging 4 towards connected piece, make elasticity
Flanging 4 is fixed on close to the side of connected piece in portion 6.
It is also possible that elastic portion 6 and flanging 4 are integrally formed, as elastic portion 6 is overlying on flanging 4 close to connected by elastic coating
Drying forms behind the side of part.
Embodiment five
As shown in figure 4, being set between connector and connected piece, including sheet sheet this embodiment describes a kind of washer
Body 2 is equipped with through-hole 5 in the middle part of ontology 2, and 2 outer rim of ontology is bent to form support portion 1 towards connected piece direction, and washer further includes logical
The arc-shaped flanging 4 of the axial upper section in hole 5, the one end of flanging 4 in 5 axial direction of through-hole connects with 1 end of support portion, in through-hole 5
The other end in axial direction is freely arranged and bends camber towards side, and 4 free end of flanging and flanging 4 are close to the side of connected piece
There is certain distance in 5 axial direction of through-hole, when flanging 4 being made to be in contact close to the side of connected piece with connected piece, flanging 4 is certainly
By having gap between end and connected piece.That is the present embodiment and the difference of embodiment one to four be, flanging 4 and support portion 1
For mutually independent component.
The utility model makes producers can be by installing, dismantling by the way that flanging 4 and support portion 1 to be arranged independently of each other
Flanging 4 controls the washer quantity with flanging 4.
Flanging 4 can be group one or more of in screw connection, clamping, Nian Jie, grafting etc. with the mode of connecting of support portion 1
It closes.
The above is only the preferred embodiment of the utility model, not makees in any form to the utility model
Limitation, although the utility model has been disclosed with preferred embodiment as above, is not intended to limit the utility model, any to be familiar with
