Abstract
The utility model relates to the technical field of electrical equipment, in particular to a detecting device for an air-conditioner controller. The detecting device for the air-conditioner controller comprises a controller (1) to be detected, and the controller (1) to be detected is placed in a mating tooling of the controller (1) to be detected, and is connected with a fuse tube (4) of the controller to be detected, a power switch (10) and a power source. The detecting device is characterized in that a relay (7) is connected between the power source and the controller (1) to be detected, and a normally open contact of the relay (7) is connected with the controller (1) to be detected. When the air-conditioner controller is in a detecting state and is reversely pressed into the testing tooling, the detecting device for the air-conditioner controller is in a protection state, and a total testing system can realize normal detection and is reliable.
Description
Technical field
The utility model relates to technical field of electrical equipment, more particularly, relates to a kind of pick-up unit that prevents that air-conditioner controller when test from oppositely placing.
Background technology
Air-conditioner controller exists more rectangle controller at present, and the controller of this shape is easy to not put into the supporting frock of controller to be measured according to correct direction when detecting, but turnback is put into.The existence of this state, brought several problems of testing:
(1) can make the forceful electric power of the supporting frock of electric controller to be measured enter the light current zone of controller to be measured, cause the controller punch through damage.
(2) testing staff is damaged.
(3) reduce testing efficient, increase maintenance cost.
From as can be seen above-mentioned, in existing controller detection technique, the reliability of serious threat controller.
The utility model content
The technical problems to be solved in the utility model provides a kind of pick-up unit that can prevent that air-conditioner controller when test from oppositely placing.
For solving the problems of the technologies described above, technical scheme of the present utility model is:
A kind of air-conditioner controller pick-up unit, comprise the controller to be measured of putting into the supporting frock of controller to be measured, controller to be measured is connected with controller protective tube to be measured, power switch, power supply, is connected with relay between power supply and the controller to be measured, and relay normally open contact is connected with controller to be measured.
Described power switch is the switch of double-throw bifurcation.
The utility model with respect to the beneficial effect of prior art is:
The pick-up unit that the utility model air-conditioner controller is surveyed; when testing, air-conditioner controller can prevent from oppositely to place to cause burning out controller; in the time of can making air-conditioner controller be in detected state oppositely to be pressed into controller, be in guard mode, whole test system can normally detect and be in reliable state again.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 the utility model circuit system figure.
Embodiment
As shown in Figure 1, the utility model comprises electric controller 1 to be measured, electric controller N line 2 to be measured, controller L line 3 to be measured, controller protective tube 4 to be measured, controller protective tube output terminal 5 to be measured, controller load 6 to be measured, relay 7, power supply N line 8, power supply L line 9, power switch 10, its connected mode is: power supply N line 8 is connected with power switch 10 with L line 9, power switch 10 is connected with controller 1 to be measured, relay 7, and relay 7 normally opened contacts are connected with controller 1 to be measured..
Controller to be measured 1 wherein is the rectangle controller, the power supply N line interface that electric controller N line 2 to be measured is a controller to be measured, the power supply L line interface that controller L line 3 to be measured is a controller to be measured, the protective tube 4 of controller 1 to be measured is controller own protective tube or fuse, protective tube 4 output terminals 5 of controller 1 to be measured are the output terminal of power supply from protective tube 4, controller 1 load 6 to be measured is for entering the load device of controller itself from protective tube 4 output terminals, relay 7 is miniature relay JZC-32F, power supply N line 8 is the N line of external power supply, power supply L line 9 is the L line of external power supply, and power switch 10 is the switch of double-throw bifurcation.
Workflow of the present utility model is as follows:
When the rectangle controller correctly was pressed into the supporting frock of controller to be measured, because in the right direction, relay 7 got electric from protective tube 4 output terminals, the normally opened contact adhesive, controller 1 to be measured.When the rectangle controller error is pressed into test fixture; promptly the forceful electric power zone of controller 1 to be measured is turned to the light current zone and since relay 7 not electric, keep disconnection so usually open the contact; electric controller 1 to be measured must not be electric, thereby protect electric controller 1 to be measured not punctured by forceful electric power.
Claims (2)
1. air-conditioner controller pick-up unit, comprise the controller to be measured (1) of putting into the supporting frock of controller to be measured, controller to be measured (1) is connected with controller protective tube to be measured (4), power switch (10), power supply, it is characterized in that, be connected with relay (7) between power supply and the controller to be measured (1), relay (7) normally opened contact is connected with controller to be measured (1).
2. air-conditioner controller pick-up unit according to claim 1 is characterized in that: described power switch (10) is the switch of double-throw bifurcation.
