US Patent:

40865487, Apr 25, 1978

Filed:

Dec 29, 1976

Appl. No.:

5/755396

Inventors:

Theodore W. Robbins - Winston-Salem NC
Raymond O. Terry - Winston-Salem NC

Assignee:

Western Electric Company, Inc. - New York NY

International Classification:

H01P 122
H01H 1900
H01H 142
H01H 1100

US Classification:

333 81R

Abstract:

A switchable attenuator includes a split housing assembly formed of interlocking cover and support members. A plurality of rocker arms are mounted for pivotable movement between the cover and the support members and each rocker arm has lugs formed on opposite ends thereof which receive respective ones of a pair of shorting bars. Electrical circuit connectors, coupled to an attenuator circuit mounted adjacent to the support member, are aligned in pairs with each pair being positioned to receive a respective one of the pair of shorting bars associated with each rocker arm. The rocker arms are selectively pivoted to cause the shorting bars to move into and out of engagement with the electrical circuit connectors aligned therewith to selectively provide attenuation of different magnitudes to an external circuit.

International Classification:

H01P 122

US Classification:

333 81R

Abstract:

An attenuator, which can readily provide balanced as well as unbalanced attenuation in a plurality of external circuits, includes first and second circuit substrate devices and an actuating device associated with the circuit substrate devices. The first and second circuit substrate devices each provide variable magnitudes of attenuation to respective ones of the external circuits such as, for example, signal transmission lines. The actuating device couples the first in the alternative, and second circuit substrate devices simultaneously or the first and second circuit substrate devices separately to their respective external circuits so as to produce desired magnitudes of balanced or unbalanced attenuation in the external circuits.

Assignee:

Western Electric Company, Inc. - New York NY

International Classification:

H01P 122

US Classification:

333 81R

Abstract:

A switchable attenuator assembly includes a housing, a plurality of rocker arms mounted for pivotable movement within the housing, and a pair of shorting bars associated with each rocker arm. Each shorting bar of the pair of shorting bars associated with each rocker arm is coupled to a respective end of the rocker arm and is aligned with electrical connectors which extend from an attenuator circuit aligned with and adjacent to the housing. The rocker arms are selectively pivoted to cause the shorting bars coupled thereto to move into and out of engagement with their respective electrical connectors to provide attenuation of selected magnitudes to an external circuit.
