An electrical connector comprises a housing configured to house an interconnect mechanism, which defines an on-axis plane that is coplanar with the long axis of the interconnect mechanism. The joining bolts are arranged in a direction of a tensile load F. The outer circumferential portion corresponds to a first region where a first plurality of reinforced fibers is partially disposed in parallel along the curved line for bending. Through use of the present invention, users may keep metallic objects in service for longer periods, because such objects may be safely taken closer to the fatigue fracture point. The shape of the spacer is adapted to avoid interference with the restricting member. The cone shaped radiator has a second vertex region that is electrically connectable to a feed element mounted through the aperture of the cone shaped ground element.
