Embodiment
With embodiment the utility model is described in further detail with reference to the accompanying drawings below:
According to Fig. 1 to Fig. 4, the utility model comprises: base 1, be fixed with bayonet socket tube 2 on the described base 1, fixedly elastic device and probe 3 in bayonet socket tube 2 bottoms, be connected with the edge on the described elastic device perpendicular to the reciprocating location-plate 4 of bayonet socket tube 2 bottom direction, described location-plate 4 is provided with and described probe 3 corresponding positioning hole 5; Described elastic device comprises guide post 6 and spring 7, described guide post 6 passes the hole on the location-plate 4 and is fixed on the bayonet socket tube bottom by nut, described spring 7 is sleeved on the described guide post 6, and described spring 6 one ends connect bayonet socket tube bottom, other end connected positioning plate 4.Described guide post 6 is at least one, and described guide post 6 is provided with two under the preferable case, and is fixedly mounted on the both sides of probe 3.The location hole 5 of described location-plate 4 is corresponding with described probe 3, and described location hole 5 is used to install indicator light, because the installation screw thread place of each indicator light all has two little planes, can utilize these two planes to position.Location hole 5 is made according to the size of indicator light, has two planes equally, can cooperate with indicator light.The location-plate that can change on positioner can use different location-plates to position for the indicator light of different size different model; The side of described base 1 is provided with mains switch 8, be used for input AC 220V voltage, surface near the bayonet socket tube on the base 1 is provided with AC and DC diverter switch 10, be used to switch alternating current and direct current, to there being light-emitting diode 9 to be used to refer to the disconnection and the closure of switch, when switching to alternating current, the pairing light-emitting diode of alternating-current switch brightens on described AC and DC diverter switch, when switching to direct current, the pairing light-emitting diode of dc switch brightens.
After indicator light was packed into, because the effect of spring, probe did not contact with indicator lamp terminal, and touch switch also is in off-state.Press indicator light, length of spring compressed, probe contacts with indicator light, and as shown in Figure 5, touch switch is connected, the entire circuit conducting.
Indicator light checkout gear internal circuit as shown in Figure 6, mains switch Q1 connects the 220V AC power, Q1 can control the break-make of entire circuit; Circuit behind the mains switch is divided into two-way, and one tunnel process relay K 2 connects probe; Other one the tunnel meets transformer T1, through output 12V direct current behind the current rectifying and wave filtering circuit of diode D1 and capacitor C 1 composition, connects probe through relay K 1 again; Between current rectifying and wave filtering circuit and relay K 1, be connected with control circuit, control circuit comprises single-pole double-throw switch (SPDT) Q2, succeed the coil of electrical equipment K1, K2 respectively, be used for conducting and the disconnection of control relay K1, K2, and then control circuit switches between AC and DC, and connecting resistance R1 and light-emitting diode H1 and resistance R 2 and light-emitting diode H2 purchase and constitute the loop respectively on the branch road of connecting coil behind the switch Q2.
The concrete course of work of entire circuit: closed mains switch Q1, single-pole double-throw switch (SPDT) Q2 is pushed DC 12V, because circuit is connected, transformer T1 work this moment, through exportable direct current 12V voltage behind the rectifying and wave-filtering of diode D1 and capacitor C 1, at this moment, the Q2 dc switch conduction, the light-emitting diode H1 of corresponding alternating-current switch can be luminous, but probe, relay are not still connected.When the indicator light to be measured of packing into, and press down to make and contact with probe, stir touch switch, circuit is connected, relay K 1 adhesive, probe go out to have direct current 12V output, and can detect the quality of indicator light this moment, the performance that indicator light is described if indicator light brightens is relatively good, and this indicator light is not substandard products if indicator light works; Equally, if switch is pushed AC 220V place, light-emitting diode H2 can be luminous, the indicator light to be measured and pressing down of packing into, and circuit is connected, relay K 2 adhesives, probe output AC 220V voltage, whether the quality that can detect indicator light this moment is qualified.
Use the course of work of this checkout gear: select suitable location-plate, pass location-plate with guide post and be installed on the bayonet socket tube, and contact with the spring of suit on the guide post; Attaching plug meets AC 220V, presses Switching Power Supply Q1, energized; Utilize switch Q2 to select suitable output voltage (AC220V or DC 12V); Indicator light is put into location hole on the location-plate, rotate indicator light gently, make indicator light side and location-plate fixation, press indicator light then, hear slight sound, show the touch switch closure, the relay adhesive, circuit is connected.If indicator light is luminous, the expression product is qualified.
Detect the indicator light of other installation dimension if desired, only need replacing and the corresponding location-plate of indicator light to get final product.
The embodiment of the above is a better embodiment of the present utility model; be not to limit concrete practical range of the present utility model with this, the equivalence variation that all shapes according to the utility model, structure are done all is included in the protection range of the present utility model.
