Embodiment
1,2,3 a kind of embodiment of the present invention is described by reference to the accompanying drawings.
A kind of long delay time small-sized sealing release delay relay, is made up of cover 1, base plate 2, support 3, upper strata printed board 4 and lower floor's printed board 5; 3, described support is welded in base plate 2 both sides, and upper strata printed board 4 is arranged on support 3 top, and lower floor's printed board 5 is arranged on support 3 bottom; Described upper strata printed board 4 is welded with resistance R1, resistance R3, resistance R4, diode V1, diode V2, voltage-stabiliser tube V3, voltage-stabiliser tube V4, unijunction transistor V5 able to programme and sealing magnetic latching relay J; Described lower floor printed board 5 is welded with Large Copacity solid tantalum electric capacity C1, C2; Described base plate 2 is packaged with exit 1 pin, exit 2 pin, exit 3 pin, exit 4 pin, exit 5 pin, exit 6 pin, exit 7 pin, exit 8 pin by glass insulator, arranges perpendicular to base plate 2 with 5.08mm × 5.08mm normal pitch; Described cover 1 to be enclosed within support 3 and and base plate 2 sealed by electron beam welding.Described resistance R1 is the fixed resistance arranging delay time minimum value; The adjustable resistance R2 of regulating delay time is connected with between described exit 1 pin and exit 8 pin.Wherein compare and driving element using programmable unijunction transistor V5 as current potential, using the contact of sealing magnetic latching relay J as output switching contact, and electric connecting relation insulation tetrafluorinated line connects.
Operation principle: the RC discharge and recharge time delay principle that to adopt with programmable unijunction transistor V5 be core.After input switches on power, (exit 2 pin adds input voltage positive pole, exit 6 pin adds input voltage negative pole), input voltage is by the coil II of J-2(magnetic latching relay J)-R4(current-limiting resistance) – V1(unilateral diode) path is to C1(storage capacitor) charging, drive magnetic latching relay J action (exit 4 pin and exit 7 pin are connected simultaneously, exit 5 pin and exit 7 pin disconnect), C1 charging voltage value approximates V3(voltage-stabiliser tube) and V1(unilateral diode) difference; Input voltage is simultaneously by R3(current-limiting resistance) – V2(unilateral diode) path is to C2(storage capacitor) charging, C2 charging voltage value approximates V4(voltage-stabiliser tube) with V2(unilateral diode) difference.After input is cut off the electricity supply, time delay starts to start, electric capacity C1 is by resistance R1, R2 electric discharge, electric capacity C1 voltage constantly declines, when the G terminal voltage of V5 is lower than A terminal voltage and when exceeding motivation value (delay time arrival), V5 conducting, thus make electric capacity C2 by the coil I of J-1(magnetic latching relay J) form discharge loop, for the coil of magnetic latching relay J provides working pulse, drive magnetic latching relay J action, relay contact switches (exit 4 pin and exit 7 pin disconnect, and exit 5 pin and exit 7 pin are connected).Resistance R1 is relay fixed resistance, in order to arrange delay time minimum value; Resistance R2 is external adjustable resistance, and regulate R2 resistance, delay time can be adjustable in minimum value to 1200s.
