State the extruding bad student's elastic deformation by wiring board conductive hole of second elastic, and then produce anti-after described elastic component pressurized pressurized
To elastic force, this elastic force makes described first elastic and described second elastic be fully contacted with described conductive hole, thus
Make described flake terminal the most reliable with the connection of wiring board.Further, described flake terminal increases with described wiring board contact area
Greatly, interaction force increases, thus reduces described flake terminal and the contact resistance of described wiring board, and then reduces caloric value,
Therefore this flake terminal is applicable to the occasion of big electric current.
The one that the present invention provides, described fish eyelet connects near one end of described base portion and near one end of described pin part
The logical semicircle orifice that is provided with, described semicircle orifice and described fish eyelet junction are provided with fin, by using this structure can make bullet
Property portion be easier to occur elastic shrinkage when being squeezed, and then it is the most laborsaving to make terminal insert during the conductive jack of wiring board.
In the present invention, at the outer corners of described elastic, it is provided with fillet, can effectively prevent flake end by arranging fillet
Son is during plug-in mounting, and the outer corners of elastic destroys the conductive jack of wiring board, is also avoided that flake terminal table simultaneously
The tin coating in face is destroyed.
In the present invention, the end of described pin part is formed around inclined-plane, arranges described inclined-plane and can be beneficial to terminal insertion circuit
In the conductive jack of plate.
Accompanying drawing explanation
In order to be illustrated more clearly that the specific embodiment of the invention or technical scheme of the prior art, below will be to specifically
In embodiment or description of the prior art, the required accompanying drawing used is briefly described, it should be apparent that, in describing below
Accompanying drawing is some embodiments of the present invention, for those of ordinary skill in the art, before not paying creative work
Put, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
