PTC heater withstand voltage test bench structure

Abstract

The invention discloses a voltage-resisting test board structure of a PTC heater and belongs to the technical field of devices for testing electronic and electrical components. The voltage-resisting test board structure comprises a frame, a group of insulating spacer blocks, an electric controller, an insulating push plate, a warning mechanism and an insulating push plate drive mechanism, wherein an insulating board panel is fixed on the front side of the top of the frame; an insulating base plate is fixed on the rear side of the top of the frame; the insulating spacer blocks are fixed on the insulating base plate; a space between adjacent insulating spacer blocks is a conductive reed extending chamber; the electric controller is arranged at the top of the frame; the front side of the insulating push plate is arranged at the upper part of one end of each insulating spacer block far away from a spacing interval; the rear side of the insulating push plate is connected with the insulating base plate; an electrode mechanism is arranged at the front side of the insulating push plate, extends into the conductive reed extending chamber and is electrically connected with the electric controller; the warning mechanism is fixed on the upper part of the insulating push plate and electrically connected with the electric controller; the insulating push plate drive mechanism is arranged on the insulating base plate and electrically connected with the electric controller. The voltage-resisting test board structure is high in test efficiency, low in manipulation strength and also good in safety, reduces labor investment and satisfies the requirements on testing speed of industrial enlarge production.

Description

technical field [0001] The invention belongs to the technical field of electronic and electrical component testing devices, and in particular relates to a PTC heater withstand voltage test bench structure. Background technique [0002] Because PTC heaters (also known as PTC heaters, the same below) have the characteristics of fast start-up speed, good temperature control, high working reliability, excellent energy efficiency ratio and long service life, they are used to manufacture various electric heating appliances such as Key components of air conditioners, heaters, clothes dryers, dishwashers, water heaters, food processors, heated floor cleaners, etc., and even as current limiters, overcurrent protectors, overload protectors, degaussing controllers , The core component of the control and protection device such as the start controller. Among them, the application of PTC heaters on air conditioners as household appliances is relatively common, and there are many publishe...

AI Technical Summary

Problems solved by technology

[0004] In the existing technology, workers test the PTC heaters to be tested one by one. This test method has at least the following technical problems: first, the labor intensity of the workers is high; second, the test efficiency is low; third, the safety is poor ; Fourth, a lot of manpower is invested, resulting in a waste of labor resources

[0005] In the published Chinese patent literature, various technical information about the withstand voltage test device for PTC components can be seen. A typical example is "a PTC electric heater power and withstand voltage test integrated machine" recommended by the authorized announcement number CN203414522U. Since this patent can only be used every A PTC electric heater is tested for the first time, so the test efficiency is difficult to meet the requirements of industrial mass production of PTC heaters, especially when the withstand voltage maintenance time must be increased according to the use requirements, the efficiency is very low

[0006] Another example is that the invention patent publication number CN10410182A provides "a PTC element withstand voltage test device". The test of PTC heater products used in the aforementioned electrical products such as air conditioners, heaters, and water heaters has no technical inspiration for reference
