Abstract
A connection device of electronic equipment which provides a connection device preventing electrostatic damage and electronic equipment provided with the connection device. The connection device includes conductive terminals and lightning conductor portions disposed adjacent to and insulated from the conductive terminals, the lightning conductor portions being kept at the grounding potential through connection to a grounded conductor, thus causing static electricity discharge in the lightning conductor portions and avoiding discharge toward the conductive terminals.
Claims12
A connection device comprising:
- at least two conductive terminals for external connection, the terminals being deployed along a side-by-side direction;
- a lightning conductor disposed between the conductive terminals in the side-by-side direction, the lightning conductor being kept at a ground potential through connection to a grounded conductor to induce static electricity;
- and
- an insulating enclosure, formed of an insulating material and having the two conductive terminals and the lightning conductor thereon,
- wherein the enclosure includes a first portion protruding from and extending outside the enclosure and a second portion protruding from and extending outside the enclosure, the second portion constituting a vertical wall portion protruding higher than the first portion in a first direction perpendicular to the side-by-side direction, the first portion and the vertical wall being adjacent to each conductive terminal, and the lightning conductor being inside the vertical wall except for an exposed portion exposed at an edge of the vertical wall, and
- wherein side surfaces of the lightning conductor are covered with the vertical wall, the exposed portion of the lighting conductor and an exposed surface of the adjacent conductive terminal are at different heights in the first direction perpendicular to the side-by-side direction, and electrostatic discharge at the conductive terminals is avoided by inducing static electricity in the exposed portion of the lightning conductor wherein the lightning conductor inside the vertical wall does not extend beyond the vertical wall along the first direction perpendicular to the side-by-side direction.
