Embodiment 1
[0037] Please refer to figure 1 , Embodiment 1 of the present invention is:
[0038] A method for filling insulating glue in a load box provided by the present invention comprises the following steps:
[0039] S1. Prepare a load box with an opening, the load box is a hollow cuboid structure;
[0040] S2. From one end of the side wall opposite to the opening in the load box to the other end opposite to the one end, evenly fill HZ-703 adhesive on the inner surface of the side wall until a thickness of 5 mm is formed. After the first HZ-703 adhesive layer, stand in a vacuum environment at 20-25°C for 7-10 days;
[0041] S3, three negative high-voltage connection terminals, the first resistor, the second resistor, a diode, a Zener tube, a signal detector, a capacitor, and a ground terminal are respectively arranged on the surface of the first HZ-703 adhesive layer, and the The three negative high-voltage terminals are respectively the first negative high-voltage terminal, the s...

Abstract
The invention relates to the technical field of ignition devices for vehicles, in particular to a method for filling a load box with insulating glue. Three negative high-voltage wiring terminals, a first resistor, a second resistor, a diode, a voltage-regulator tube, a signal detector, a capacitor and a grounding end are arranged on the surface of a first adhesive layer; the peripheries of the second resistor and the voltage-regulator tube are respectively filled with adhesives with the thickness of 4mm; the periphery of the diode is filled with an adhesive with a thickness of 7 mm and the periphery of the capacitor is filled with an adhesive with a thickness of 6 mm. The upper surfaces of the first resistor, the second resistor, the voltage-regulator tube and the diode are filled with adhesives with the thickness of 5mm; the periphery of the capacitor is filled with an adhesive with the thickness of 6mm, so that the capacitor is completely wrapped in the adhesive, the insulating glueis filled without bubbles, the ignition technical characteristic test precision is high, the interference on surrounding electronic equipment is small, a high-voltage device meeting the professional technical standard requirement is selected, and the correctness of test data is ensured.
Description
technical field [0001] The invention relates to the technical field of vehicle ignition devices, in particular to a method for filling insulating glue in a load box. Background technique [0002] The traditional test method for the ignition technical characteristics of gasoline internal combustion engines is to install the vehicle ignition device to be tested into the vehicle body to realize the on-load test to simulate the actual application. However, due to the complicated operation and high cost of the test process, only sampling tests can be used. [0003] At present, some experts in China propose to replace the car body with a load box, that is, to make a load device. However, there is no ignition technology characteristic test load that meets the standard requirements in the market for purchase, and low-voltage devices are often used in series. Welding, lapping, screwing and other methods, and exposed to the air for testing. For example, when a three-pin discharger i...
