RELAY Russian patent published in 2003 - IPC

FIELD: electrical engineering; automatic control and measurement technology. SUBSTANCE: relay designed for use as component for matching output circuit of transistor- transistor logic integrated circuit incorporating control coil has metal ferromagnetic screen in the form of all-drawn rectangular-shape shell accommodating insulating base that connects leads of two-way hermetically sealed switching contact bent at right angle and those of no-former control coil to shorting diode. Hermetically sealed contact is deepened into screen through distance ensuring ratio of magnetic permeability G_hsc between screen walls and hermetically sealed contact leads to magnetic permeability G_nch of normally open pair of hermetically sealed contact limited by inequality at minimal possible clearance between screen walls and hermetically sealed contact leads positioned inside no-former control coil so that plane crossing longitudinal axes of glass envelope and non-deformed parts of tow-way hermetically sealed contact leads is parallel to base, low limit of inequality for hermetically sealed contacts and high limit for those with maximal operating magnetomotive force (MMF) at MMF_opmax/MDF_opmin ratio being not over 3. EFFECT: enhanced sensitivity and control power of relay. 2 cl, 6 dwg
