Detailed Remote Control Airplane Toy Test Considerations

Along with social progress, people's material and cultural needs continue to increase, with the development of high technology, children's toys are also constantly upgrading, they education toys are no longer satisfied the ground running remote control car, and more interested in remote control aircraft flying in the sky.
The following points must be noted that in the electric toy testing a brief explanation
Note 1: needle short-circuit
Overview: The materials used in the housing of the remote control aircraft ships foam, plastic and steel, the type of plastic foam, it could withstand the mechanical strength is relatively weak, in reasonable abuse testing, aircraft shell may be damaged so that I can steel pin short circuit. This is a simulation of a child during play due to inherently a good move, might pin, screwdriver, wire conductive objects from the toy shell hole, seam into his toys, resulting in a short circuit, causing the temperature rise too high, fire, explosions and other dangerous harm people.
Solution: 1. Reduce the positive and negative terminals of the battery chamber height of the contact piece, and it is lower than the height of the insulating baffle (for the remote control)
2 power plus protection device (for remote control aircraft)
The internal circuit package, this package can withstand abuse testing.
Note 2: Analog electronic components fail test (circuit internal problems)
Overview: either moist air or dust in the air, remote Remote Control Plane control aircraft components will have some impact, moist air at the surface of the components or materials condensation water film and into the inner material, resulting in a short circuit of the electronic components , the risk of leakage or breakdown. Short-circuit test on each of the electronic components to simulate the failure, not the production of fire or burns due to high temperature and the risk of children. The general problem here is the capacitor, transistor, IC.
Solution: 1. The power supply connected to a current-limiting resistor, PTC or fuse.
2 capacitor, a capacitor can be connected in series, the two capacitors in series.
3 battery plus protection circuit
Note 3: widgets battery
Overview: According to statistics, in the case of toys were recalled in recent years, the reasons for the recall have a lot of widgets recall accounted for 28% of the cases, because small parts can result in children choking and even death, so the widget has always been toy safety standards is a very important concern.
Abuse before and after the test, the battery (battery in ASTM F963-2008 Terms 4.25.5 for widgets batteries, EN62115 button batteries or R1 battery) without the aid of tools untouchable unless the battery compartment cover only At the same time, applying at least two independent actions are required to open.
Solution: If the battery cover, with screws tighten the battery Learning Table cover.
(2) sealing the battery in the battery compartment or toys.
Note 4: Clearance and creepage distances
Overview: The air is one of the most common and reliable electrical insulation medium. Small air gap between the different live parts to a certain extent, the medium of air in the electric field breakdown, insulation failure or temporary failure of which may result in electric shock and burn hazard, in order to prevent such a danger, according to EN62115 modified requirements of Chapter 18 the functional insulation clearances and creepage distance of not less than 0.5 mm, however, functions on the PCB insulation, in addition to their edges, clearances and creepage distances shall not be less than 0.2 mm. general aircraft battery protection circuit, this can pass.
Solution: 1. Increase the clearances and creepage distances
2 the power supply connected to a current-limiting resistor, PTC or fuse.
Note 5: reverse battery
Overview: As we all know, the electrolyte is a strong acid, a strong corrosive to skin, eyes were damaged, replace the battery, however, the operator may be battery incorrect installation, so that the battery charge and battery electrolytic liquid pool drain phenomenon, in order to prevent that danger, reverse battery placed the toy run for 24 hours, the toys should not leak hazardous substances or explosion hazard. Under normal circumstances, most of the power used best remote control car by the remote control aircraft can not replace the battery, this is mainly for aircraft remote control.
The solution of the above problems only general method for reducing the risk of toys is not the same level, when specific problems or to specific analysis and processing.
