Abstract
A connector includes a base and a connector member with a first end connected to the base and a second end opposite the first end. A first region on the connector member, located adjacent the first end, has a first impedance. A second region on the connector member, located adjacent the second end, has a second impedance greater than the first impedance. When an electro-statically charged device is connected to the connector, the electrostatic charge is dissipated relatively slowly due to initial contact with the second region of increased impedance, lowering the voltage resulting from the connection in order to protect static sensitive circuits coupled to the connector.
Claims9
An information handling system comprising:
- a housing;
- a microprocessor mounted in the housing;
- a storage coupled to the microprocessor;
- a static sensitive circuit located in the housing;
- a connector member having a varying mating surface contact with a charged connector,
- the connector member, located in the housing and coupled to the static sensitive circuit, which discharges static energy distributed over time due to an impedance of the connector that varies along its length, the impedance varying in response to varying the mating surface contact with a non-metal coating between a portion of the connector member and the charged connector.
