Embodiment
Embodiment one
Refer to shown in Fig. 1, Fig. 2, the utility model prevents the contact arm 20 that routed type conducting terminal comprises framework 10 and extends to form from described framework 10.Described framework 10 comprises the first end 11, the second end 12 that are positioned at both sides, plug-in card direction and connects the transverse wall 13 of described first end 11, the second end 12, is cut be formed with hollow bulb 14 in the middle of described framework 10 by punching press.Described contact arm 20 comprises bending part 21 that outside described first end 11 inverse bending formed, tilts upward from described bending part 21 end and extend to form contact site 22 and be tilted to towards described the second end 12 free end 23 that downward-extension formed from described contact site 22 towards the second end 12.
The second end 12 of described framework 10 is formed the sliding part 30 of free end 23 movement for described contact arm 20, described sliding part 30 is specifically formed at the pore structure on described the second end 12, described pore structure specifically adopts the mode of punching press upwards to tear described the second end 12, forms the pre-splenium 31 of arch above the free end 23 being positioned at described contact arm 20 simultaneously.Can effectively prevent electronic cards from damaging described conducting terminal when plugging because wiping is linked with dynamic described contact arm 20 thus.Change contact site 20 described in prior art inside the first end 11 of framework 10, extend the defect causing and cannot form sliding part 30 below described free end 23.
The present embodiment in the fabrication process, by below the contact site 22 of described contact arm 20 upwards against a tool, then compress described free end 23 downwards by another tool thus force described free end to enter below the pre-splenium 31 of described arch.
The present embodiment is in implementation process, and the pre-splenium 31 of described arch also can be half opening structure, namely only needs punching press to form the side of described pre-splenium 31.
Embodiment two
The embodiment of the present application two refers to shown in Fig. 3, Fig. 4, compared to embodiment one, the difference of the present embodiment is: at free end 23 place of the corresponding described contact arm 20 of the second end 12 of described framework 10, downward punching press forms sliding tray (sliding part) 15, described free end 23 described sliding tray 15 in movement with contact arm 20 described in the electron injury preventing movement.Meanwhile, for ease of the formation of described sliding tray 15, the horizontal level of described the second end 12 higher than the horizontal level of described first end 11, and forms ramp extension 131 at lateral sidewalls 13 place of described framework 10 thus.The horizontal level of the horizontal level of described sliding tray 15 bottom surface and first end 11 bottom surface of described framework 10 maintains an equal level.
