High-tension test apparatus for automobile ignition coil

Abstract

The invention relates to a high-tension test apparatus for an automobile ignition coil. The apparatus is provided with a base; a rotary disc is arranged at the centre of the base; the rotary disc is circular; circular holes are formed at the periphery of the edge of the rotary disc in a matching manner; plastic tubes are embedded in the circular holes; conductive copper columns are assembled in the plastic tubes; the conductive copper columns are uniformly distributed at the periphery of the edge of the rotary disc; the rotary disc is further provided with a fixed door cavity; the fixed door cavity is fixed on the base; a conductive chain is connected in the fixed door cavity; the conductive chain is hung at the top end of the fixed door cavity; the conductive chain is located at the outer side of the corresponding conductive copper column; the fixed door cavity is further provided with a glass stop plate; the high-tension test apparatus is further provided with an execution controller and a voltage controller. The high-tension test apparatus has the following advantages that: the ignition coil can be independently tested, and an overall loading test is not needed; the actual application condition of the ignition coil with an automobile during an actual use process is simulated, and long-time verification for the actual use process of the ignition coil is shortened.

Description

technical field [0001] The invention relates to the technical field of automobile electrical appliances, in particular to high-voltage test equipment for automobile ignition coils. Background technique [0002] With the development of the automobile ignition system, higher requirements are put forward for the reliability and life of the automobile. The automobile ignition coil is a key component of the ignition system, including the coil assembly and the high-voltage output assembly. The high-voltage output assembly is mainly composed of a high-voltage output spring. And the rubber sleeve set outside the spring. When in use, the high-voltage output end of the high-voltage output component is connected to the electrode of the spark plug, and the spring is connected to the copper electrode of the spark plug. The rubber sleeve is inserted outside the copper electrode of the spark plug to play a role of high-voltage insulation. . With the existing structure, the rubber sleeve i...

AI Technical Summary

Problems solved by technology

With the existing structure, the rubber sleeve is easy to age and harden due to long-term work in a high-temperature and high-pressure environment, and once a small gap appears between the rubber sleeve and the spark plug electrode, it will cause poor insulation and high voltage creepage to the cylinder body. This will lead to safety hazards, and at the same time, the copper spark plug electrodes will be oxidized and corroded by air, which will directly affect the reliability of the ignition system and the service life of the spark plugs.

[0003] In the prior art, the insulation performance of the ignition coil is tested after loading the vehicle. The temperature of the ignition coil has a great influence on the ignition coil due to the heat generated by the automobile engine, which has a great influence on the insulation performance of the ignition coil. error, it is impossible to determine the insulation performance of the ignition coil; in addition, the ignition coil has a long test period after loading, and it needs to be tested as a whole, so it cannot be verified separately in advance

[0004] In summary, there is an urgent need for a test device with a short test period, which can be verified in advance, has a short development period, and is easy to operate, but there is no report on this type of device at present.
