Patent ID: 7581971

Claim:
A binding post, comprising: a first conductive member including a head and a rod coupling to the head; a second conductive member receiving the rod of the first conductive member; an isolating module sandwiched between the first and second conductive members for avoiding electrical connection between the first and second conductive members; a positioning module for positioning the first and second conductive members relatively to the isolating module; and a cap mounted around the head of the first conductive member including a body, a conductive tube between the body and the second conductive member and a hole passing through the body in an axial direction of the body, with one end of the conductive tube extending into the hole and the other end of the conductive tube forming a contacting surface; wherein the second conductive member includes a hollow cylinder and an annular plate formed on one end of the hollow cylinder, with the head of the first conductive member passing through the annular plate and being outside the second conductive member; wherein the hollow cylinder of the second conductive member has two holes on the radial wall thereof and the positioning module includes two semi-annular bodies, with two protrusions being formed on two inner surfaces of the two semi-annular bodies respectively and passing through the holes to abut against the rod.
