embodiment 1
According to shown in Fig. 1 to Fig. 2, the conductive contact blade of the present embodiment, include a top conductive end 11, two the symmetrically arranged conductive arms 12 be connected with top conductive end one, and be integrally connected to the bottom conductive end 13 of conductive arm end, the top conductive contact 113 of to be contact area be in the upper surface of described top conductive end linear, the contact area of described linear is parallel with the line of two bottom conductive ends.
Overall curved of described top conductive contact, described linear contact area is positioned on described arcwall face.Can keep in touch region when such moving contact contacts with the contact area of top conductive contact is linear.
A riveted joint limit 132 and a bottom conductive contact 131 be oppositely arranged with described riveted joint limit is connected with below described bottom conductive end.The contact area of described lower surface, bottom conductive contact is linear, and this contact area is parallel with the contact area on top conductive contact.Such bottom conductive contact does not need, through the operation of riveted joint, can ensure the electric contact area that yet can form a linear between bottom conductive contact and fixed contact, be beneficial to reduction contact resistance equally, strengthen through-flow performance.
The rear described top conductive end being positioned at top conductive contact is a top bevel 111, forms the angle of 5-30 degree between top bevel and conductive arm upper surface.Top bevel is beneficial to and improves the decrement of conductive contact blade relative to moving contact.
The below described top conductive end being positioned at top conductive contact forms the bottom bevel 112 that a front end upwarps.
" top ", " bottom ", " below " etc. that relate in specification are only the relative position relations in order to each position is described, do not play substantial restriction effect to the present invention.As in Fig. 1, top conductive contact 113 is in top position relatively, therefore names to distinguish mutually with other positions with " top ".
embodiment 2
Shown in composition graphs 1 to Fig. 6, the electrical connection contact band of the present embodiment, includes one or more pieces conductive contact blades 1 described in embodiment 1, also includes flexible strip 2; The both sides of described flexible strip are equidistantly connected with the reverse arm 25 of integrative-structure, position on flexible strip between every two relative torsion arms offers assembling and positioning hole 20, the windup-degree of reverse arm is at 15-20 degree, and riveted joint limit 132 and the outer end of described reverse arm of described conductive contact blade are riveted fixing.
Described reverse arm 25 forms the bottom conductive contact limited mouth 24 coordinating with the bottom conductive contact 131 on described conductive contact blade and locate near the side of outer end.Bottom conductive contact 131 coordinates with bottom conductive contact limited mouth 24 makes conductive contact blade not produce relative displacement with flexible strip on the reverse arm length direction of flexible strip.
