As shown in Figure 2, inserted

sheet

19,20 is inserted lower cover 21 relevant positions, fix, with line itself and gear-box 15, microswitch 13, accessory power outlet 10 are coupled together by Fig. 2 principle, cover down gear-box 15 is arranged respectively, the fixed groove of the vertical columns of microswitch 13 and accessory power outlet 10, be fixed to the relevant position respectively; The switch driving lever is fixed to down covers on the corresponding vertical columns; Hand switch is fixed on down covers on the corresponding grooves; With line microswitch 13 and diode 9, accessory power outlet 10 are coupled together by Fig. 2 principle; Diode 9 and resistance 14 are coupled together; Resistance 14 is coupled together with LED 16; Diode 9, resistance 14, LED 16 are fixed on the corresponding fixed position of lower cover; Translucent cover is installed on the lower cover corresponding grooves; Loam cake, lower cover are lumped together; Three jacks are arranged on the assignment disk group, corresponding with three grabs of panel, panel is stuck on the assignment disk group; The assignment disk group of buckling well panel is placed in the corresponding circular groove of loam cake; On to cover three jacks corresponding with the grab of middle seat, middle seat is buckled in cover.

The effect that mechanical timer produced of this band mini light night is as follows:

On assignment disk that time set is good, timer to be received on the power supply, the gear on the gear-box begins to rotate, and simultaneously by the transmission between gear, drives assignment disk and rotates.When not reaching the Preset Time section, the COM of microswitch end is connected with normal-closed end (NC), and power supply is connected to the mini light night circuit, and the mini light night circuit is lighted, because the COM end disconnects the power output socket no-output with Chang Kaiduan (NO); When reaching the ON time section that presets, the timer latch can rotate by the pull switch driving lever, and the switch driving lever is pushed down the button of microswitch, microswitch COM end is connected with Chang Kaiduan, power supply is connected to power output socket, and at this moment, power output socket has output; Because the COM end is disconnected with normal-closed end, power supply and mini light night circuit are disconnected, and mini light night extinguishes.In any time section that presets, hand switch is got to the ON position, hand switch compressing switch driving lever couples together with Chang Kaiduan (NO) by the COM end of switch driving lever with microswitch, and this moment, power output socket had output, and mini light night extinguishes.

Fig. 3 is the schematic diagram of the electronic timer of band mini light night

As shown in Figure 3, power supply is imported by power supply, and input circuit is connected with hardboard, power output socket, mini light night circuit; Behind power supply input hardboard, by R1, C1 resistance-capacitance depressurization, then by current-limiting resistance R2, entering D1, D2, D3, D4 forms rectifier bridge and carries out rectification, at process electrochemical capacitor C2, after capacitor C 3 filtering, through the R3 current-limiting resistance, at Z1 negative pole voltage stabilizing 24V DC voltage, after this circuit divides three the tunnel: the one tunnel through the R4 divider resistance, again through the D5 buck diode, form the DC voltage of 1.2V at Z2 voltage-stabiliser tube negative pole, for E1 rechargeable battery charging with for control panel provides the DC voltage of 1.2V, C4 electrochemical capacitor, C5 ceramic disc capacitor are that 1.2V carries out filtering simultaneously; Two the tunnel, the DC voltage of 24V is provided for the K1 relay; Three the tunnel,, be connected with signal port J1_B through diode D7 through the R5 step-down.The J1_B port of IC control circuit is connected with the J1_B port of J1.The J1_B port, according to the setting of IC control circuit, output high level or low level through diode D7, are carried out break-make control to Q1.When the Q1 conducting, understand the closed and disconnected of control relay K1 accordingly.The mini light night circuit is made up of commutation diode D8, current-limiting resistance R6, LED and relay K 1, electronic timer input power firestreak L is connected with commutation diode D8, commutation diode D8 is connected with current-limiting resistance R6, current-limiting resistance R6 is connected with LED, and the LED output is connected with electronic type Timing power supply zero line N by a normally closed binding post of relay K 1.

In sum, the electronic timer of this band mini light night says that the effect that produces is as follows:

Timer is connected with the mains, and setting completed with timer by setting key.When not reaching the Preset Time section, signal pins J1_B provides low level, and triode Q1 is in not conducting, and relay is in normally off, and promptly 1 pin of relay K 1 is connected with 2 pin, and power supply is connected to the mini light night circuit, and the mini light night circuit is lighted; Because relay K 1 is a normally open, so the power output socket no-output; When reaching the ON time section that presets, signal pins J1_A provides high level, triode Q1 conducting, and relay K 1 adhesive, promptly 1 pin of relay is connected with 3 pin, and power supply is connected to power output socket, and at this moment, power output socket has output; Because relay K 1 adhesive, 1,2 pin disconnect, so mini light night circuit and power supply disconnect, mini light night extinguishes.

More than the effective little neon lamp of LED light-emitting diodes among two kinds of embodiment replace also having same effect.
