Abstract
The utility model discloses a power-off protection testboard comprising an outer casing and a workpiece installation seat, wherein the workpiece installation seat is arranged on the outer casing, and the workpiece installation seat is connected with a power source. The power-off protection testboard also comprises a breaker, wherein the breaker is connected with the outer casing, and the breaker is connected between the workpiece installation seat and the power supply. The power-off protection testboard has the advantages that the breaker is additionally installed in a circuit, and when electricity is leaked to the outer casing of the testboard, the power supply of the power source is cut off by the breaker to prevent electric leakage from continuously staying on the testboard to generate impact on a test product.
Description
Technical field
The utility model relates to a kind of test board, particularly a kind of power-off protection test board.
Background technology
The electric product leakage tests is to detect simultaneously by a plurality of products of test board one-step installation, in case the product electric leakage is arranged, provides corresponding prompting.But there is such problem in existing test board: product is mounted on the test board shell table top, in case electric leakage, the test board shell is metal, will cause outer casing electrification, this will impact other product in test on the test board, damage of product or other situation occur.
The utility model content
The utility model purpose: for the problems referred to above, the purpose of this utility model provides a kind of test board that can play a protective role during to the product leakage tests, and impact on test products prevents from leaking electricity.
Technical scheme: a kind of power-off protection test board; comprise shell, workpiece assembling seat; described workpiece assembling seat is arranged on the described shell; described workpiece assembling seat is communicated with power supply; also comprise isolating switch; described isolating switch is connected with described shell, and is connected between described workpiece assembling seat and the described power supply.
Beneficial effect: compared with prior art, the utility model has the advantages that and install isolating switch additional to circuit that when leaking off to the test board shell, the isolating switch power supply of cutting off the electricity supply prevents that electric leakage from continuing on test board, exerts an influence to the product in test.
Description of drawings
Accompanying drawing the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As shown in drawings; a kind of power-off protection test board; comprise shell 1, workpiece assembling seat 2, isolating switch 3; workpiece assembling seat 2 is arranged on the shell 1; on the workpiece assembling seat 2 some products to be tested can be installed simultaneously; workpiece assembling seat 2 is communicated with power supply 4, and isolating switch 3 is connected with shell 1 and is connected between workpiece assembling seat 2 and the power supply 4.
When product test leaked off to shell 1, isolating switch was had an effect, cut off the electricity supply 4 with workpiece assembling seat 2 between be communicated with, and the outage of whole test board is protected.
