To another element or it may be simultaneously present centering elements.Term as used herein " vertical ", " horizontal ", " left side ",
" right side " and similar statement are for illustrative purposes only.
Unless otherwise defined, all of technologies and scientific terms used here by the article is led with belonging to technology of the present utility model
The implication that the technical staff in domain is generally understood that is identical.It is simply in term used in the description of the present utility model herein
The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term as used herein " and/or " include
The arbitrary and all combination of one or more related Listed Items.Describe in detail below in conjunction with the accompanying drawings of the present utility model
Concrete operating principle.
As shown in figure 1, a kind of high temperature resistant and the tinned wird structure with environmental protection characteristic, including some single copper cash,
The single copper cash includes copper core 1 and the tin alloy layers 2 being wrapped in outside the copper core, and the thickness of the tin alloy layers is 0.5 μ
m-2μm.Perfluoroethylene-propylene glue-line 3, the single copper cash and perfluoroethylene-propylene glue are filled between the single copper cash
Layer is wrapped with polytetrafluoroethylene floor 4, and the polytetrafluoroethylene floor is wrapped with anti-corrosive rubber layer 5, the polytetrafluoroethylene (PTFE)
The thickness of layer is 1 μm -5 μm, and the surface of polytetrafluoroethylene floor is provided with several grooves 6.The cross section semicircular in shape of the groove,
In the bottom of groove, square groove 7 is set.Due to being not easy to combine between polytetrafluoroethylene floor and anti-corrosive rubber, in order to make two
Person, which combines closely, sets groove, and when being slotted in processing by laser gun, then wrapping up anti-corrosive rubber layer, rubber can be embedded into recessed
