Antenna-effect suppessor method and device particularly for thermocouples and other dissimilar metal conductor combinations
First Claim
1. An electrical device for establishing a separable electrical connection with at least two external conductors of dissimilar metals, said device comprising:
- a housing formed of electrically insulating material including a conductor guide groove;
an electrical contact element supported by said housing, said contact element having first means thereon capable of separately engaging at least a first external electrical conductor to define a portion of an electrical path of finite length extending through and away from said device,said housing being totally transversely separable across a parting plane to form two housing halves, a ferrite element divided into components which nest in each of said housing halves and having a conductor passage extending therethrough, said ferrite element being positioned relative to said housing so that said conductor passage surrounds at least an axial portion of said electrical path extending through and away from said electrical device along said guide groove beyond said ferrite.

Abstract
The invention relates to electrical devices which include at least one pair of dissimilar metal members with respective surfaces for bringing into contact with each other or with other receptors to establish an electrical connection, and antenna-effect inhibiting means such as a ferrite composition are disposed adjacent to the connection surface of at least one of the contact members. In a form of the invention for use with single wires or a pair of multiple wires, each wire is provided with an individual antenna-effect inhibiting means, such as a ferrite housing, adjacent to a connector thereon. The invention also provides a method of making an electrical connector, having at least two electrical conduction elements of dissimilar metals, which includes steps of forming at least two dissimilar metal conductors to engage corresponding metal conductors at a junction, providing a ferrite element mounted in proximity to at least one connector near said junction and providing means to measure and display the current passing said junction. In a further method in accordance with the invention, operating an electrical circuit comprises providing at least two conductors of dissimilar metals, providing a ferrite element near at least one of those conductors of dissimilar metals at a junction with a conductor of the metal, passing an electric current through the at least two conductors, and measuring that current.
