A sequence driving circuit composed of a transformer, a rectification circuit and N grades of conduction circuit units connected in parallel is arranged, wherein the first grade of conduction circuit unit is a direct circuit unit and the other N-1 conduction circuit units are time delay circuit units, a relay coil is arranged in each of the conduction circuit units, and relay contacts corresponding to the relay coils are arranged in the live wire electrodes of the corresponding jacks. With the power socket with time delay, the startup time of a portion of computers can be dispersed, safe start-up of all computers in a whole computer room can be ensured, simple switch-on of a main switch will not cause air switch tripping, and manual trouble will not be brought to operators.

Description

A kind of supply socket with time-delay

Technical field

The utility model relates to a kind of supply socket with time-delay.

Background technology

Present school more and more payes attention to Informalized teaching, Informalized teaching be unable to do without computer, the computer of machine room is important instructional media, and the computer room administrator is convenient for power management, often controls a plurality of computer power supplies with an air switch, there are so a lot of hidden danger, numerous computer, displays start simultaneously, and immediate current is very large, and air switch can trip, if adopt the air switch of larger current limliting, brought again potential safety hazard.Therefore, demand better, safer product urgently and occur.

The utility model content

The purpose of this utility model provides a kind of supply socket with time-delay, can disperse the part launch computer time, so that whole machine room computer security starts, simply closes total lock and also can not cause sky to hold tripping operation, can not bring artificial trouble to the operator again.

For achieving the above object, the utility model is taked following design:

A kind of supply socket with time-delay, comprise a jack body, supply the external plug insertion with the jack of plugged with N on this jack body, the built-in firewire electrode corresponding with each jack of jack body, zero wire electrode and ground wire electrode, each homonymy electrode is connected in parallel; It is characterized in that: set an order drive circuit, this order drive circuit is comprised of a transformer, rectification circuit and N level turning circuit unit parallel with one another, wherein first order turning circuit unit is the direct circuit unit, be N-1 delay turn-on circuit unit after first order turning circuit unit, in each turning circuit unit, be equipped with a relay coil, and in the firewire electrode of corresponding jack, corresponding with it relay contact be set.

Described each time delay circuit unit is comprised of a triode, a resistance and a charging capacitor; This triode is NPN type triode; It is good adopting the low-power transistor of 3DG6,3DG57 or 9014 models.

The utility model has the advantages that: use safety, can overcome effectively that numerous electrical equipment starts simultaneously and the defective of the air switch tripping operation that causes.

Below in conjunction with drawings and the specific embodiments the utility model is described in further details.

Embodiment

The foundation structure of the supply socket of the utility model band time-delay is: comprise a jack body, supply the external plug insertion with the jack of plugged with one group of N (N represents the natural number more than 1) on this jack body, the built-in firewire electrode corresponding with each jack of jack body, zero wire electrode and ground wire electrode, each homonymy electrode is connected in parallel.

Consult Fig. 1, shown in Figure 2, innovative point of the present utility model is: set an order drive circuit, this order drive circuit is by transformer B1, rectification circuit (d1, d2, d3 and d4 constitute) and one group N turning circuit unit composition parallel with one another, wherein first order turning circuit unit is the direct circuit unit, be N-1 delay turn-on circuit unit after first order turning circuit unit, in each turning circuit unit, be equipped with a relay coil KN(N and correspond to 1 or 2,3 ... corresponding with it relay contact K1 is set respectively N), and in the firewire electrode of corresponding jack, K2, K3 ... KN.

Fig. 3 is the order drive circuit electrical schematic diagram of supply socket one specific embodiment of the utility model band time-delay.This is an order drive circuit that is comprised of three triodes, comprise the turning circuit unit that level Four is parallel with one another, the first order is the direct circuit unit, directly be in series with relay coil K1 by resistance R 1, be three delay turn-on circuit unit after this level is led the direct circuit unit, respectively by charging capacitor C1(or C2, C3), resistance R 2(or R3, R4), triode Q1(or Q2, Q3) with relay coil K2(or K3, K4) consist of, at charging capacitor C1(or C2, C3) the positive interpolar of negative pole and general supply arranges resistance R 2(or R3, R4), this charging capacitor C1(or C2, C3) negative pole meets this triode Q1(or Q2, Q3) base stage; Correspondence, as shown in Figure 4, corresponding with it relay contact K1, K2, K3 and K4 are set respectively in the firewire electrode of corresponding jack, L is the input point of this socket live wire, L1, L2, L3, L4 are the output point of socket live wire.Its operation principle is: when power supply one is connected, the conducting of K1 elder generation, because the voltage at charging capacitor C1 capacitor two ends can not suddenly change, Q1, Q2, Q3 wouldn't conductings, when the voltage at charging C1 capacitor two ends reaches above predetermined design 0.6 volt, Q1 is conducting at first, the K1 coil gets electric, when the Q1 emitter voltage rises simultaneously, so that the Q2 base voltage rises, so when the Q2 base stage surpassed 0.6 volt, Q2 is conducting also.The K2 coil then electric, when simultaneously the Q2 emitter voltage rose, so that the Q3 base voltage rises, the K3 coil got electric.D1, d2, d3, d4 are rectifier diode, and B1 is transformer.
