Abstract

The utility model discloses a board-to-board electric connector, comprising an insulating shell and plural conductive terminals which are contained and positioned in the insulating shell. The insulating shell is provided with a bottom wall used for contacting a circuit board. The insulating shell is made of a liquid-crystal-polymer material which is provided with good heat resistant and flow formability. The conductive terminals are made of a phosphor-bronze material which is provided with good fitting elasticity. Furthermore, the bottom wall of the insulating shell is provided with plural convex poles which protrude at the surface of the bottom wall. Thus, the convex poles can be inserted in a positioning hole which is formed on the circuit board relatively for improving the positioning accuracy when the electric connector is carried out the surface binding.
