Embodiment
1,2,3 a kind of embodiment of the present invention is described by reference to the accompanying drawings.
A long delay time small-sized sealing release delay relay, is comprised 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 tops, and lower floor's printed board 5 is arranged on support 3 bottoms; In described upper strata printed board 4, be welded with resistance R 1, resistance R 3, resistance R 4, diode V1, diode V2, voltage-stabiliser tube V3, voltage-stabiliser tube V4, unijunction transistor V5 able to programme and sealing magnetic latching relay J; In described lower floor printed board 5, be welded with large capacity solid tantalum capacitor C 1, C2; On described base plate 2, by glass insulator, be 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, with 5.08mm * 5.08mm normal pitch, perpendicular to base plate 2, arrange; Described cover 1 is enclosed within on support 15 and with base plate 2 and seals by electron beam welding.Described resistance R 1 is for arranging the fixed resistance of delay time minimum value; Between described exit 1 pin and exit 8 pin, be connected with the adjustable resistance R2 of capable of regulating delay time.Wherein using programmable unijunction transistor V5 as current potential comparison and driving element, using the contact of sealing magnetic latching relay J as output switching contact, and electric connecting relation connects with insulation tetrafluorinated line.
Operation principle: adopt and take the RC that programmable unijunction transistor V5 is core and discharge and recharge time delay principle.After input switches on power, (exit 2 pin add input voltage positive pole, exit 6 pin add 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, capacitor C 1 is discharged by resistance R 1, R2, capacitor C 1 voltage constantly declines, when the G of V5 terminal voltage also surpasses motivation value lower than A terminal voltage (delay time arrival), V5 conducting, thereby make capacitor C 2 by the coil I of J-1(magnetic latching relay J) formation 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 R 1 is relay fixed resistance, in order to delay time minimum value to be set; Resistance R 2 is external adjustable resistance, regulates R2 resistance, and delay time can be in minimum value to adjustable in 1200s.
