Description

BACKGROUND OF THE INVENTION The present invention relates to the dissipation of electrostatic charge in electrical wiring associated with data processing and/or other equipment, and more particularly to electrical connectors that dissipate the energy of this charge. Involved.

Description of the Prior Art It is known in the prior art that static electricity is a problem that exists in electrical equipment. For example, this is a problem in data processing (r')P) devices.

Electrostatic discharges often occur when an operator comes into contact with the P device, either directly or indirectly through intermediate devices.

Once this contact is established, the charge carried by the operator becomes D
Transferred to P device. Such charge transfer often damages and degrades sensitive electronic components. Furthermore, parity and/or data errors may also occur.

Static electricity is a positive or negative charge (absence or presence of electrons, respectively), and the accumulation of charge results from the friction of certain opposing objects. When one of these objects comes into contact with yet another object at a different potential, a transfer of electrons occurs.

Charge transfer ceases when both objects reach equilibrium, or when subsequent disturbances render two or more charge transfers completely impossible.

Static charge accumulation can also occur due to frictional electricity, such as when a person walks across a room. The amount of static electricity generated in this way depends largely on the person's shoes, the type of floor he walked on, and the humidity of the air.

In a typical instar discharge, 5.0 between the discharge side and the receiving side
There is a potential gradient from 00 V to 12,0 OOV.

However, 25,000 OOV is not abnormal.
