How do I test the waterproof connector?

Waterproof connector is a kind of connecting device used to connect the power supply of large electrical equipment in our daily life and in the production of enterprises. It is an indispensable and necessary product for connecting electrical appliances in every large enterprise.
The waterproof connector is a step further than the traditional waterproof connector, which not only has the connection function of the traditional connector but also has the waterproof function that the traditional connector does not have.


It can indirectly bring a lot of profits to the enterprise is that its waterproof function in the actual application for the enterprise's large electrical appliances to bring safety, safety of enterprise electrical appliances can be assured after the production activities.
In the previous connector waterproof function, if the connector into the water that is not damaged by the connector, but the entire electrical appliances are likely to be damaged, the machine damage enterprises can not be able to produce will directly bring economic losses to the enterprise.
So we say waterproof connector indirectly brings a lot of profit to the enterprise.
But the waterproof connector has such a good waterproof effect is not accidental, but after a strict performance test, now to tell you about the waterproof connector performance test requirements.


General waterproof connector test is divided into a number of steps, respectively to be tested is: waterproof connector electrical strength, insulation resistance, salt spray test, waterproof performance, mechanical life and compatibility.
These are the performance tests that a waterproof connector must undergo after it is successfully manufactured. These tests are required for a waterproof connector to be qualified for delivery.


The test of the electrical strength of the waterproof connector shall be conducted at room temperature and test voltage AC1500V/50HZ between the conductor and the insulator for the presence of breakdown or flashover after one minute, and the test shall also check whether the superleakage current is less than 2mA, less than which is the qualified product.
The test method for insulation resistance is similar to that for electrical strength, except that the test voltage is changed to DC500V for testing.


The salt fog test for certain preparatory work, the first thing to prepare some salt bath concentration in five percent sodium chloride solution, make the waterproof connector in this solution immerse 48 hours later, check the waterproof connector if the impact performance of corrosion is considered unqualified, if not influence the performance of corrosion is qualified.
Waterproof performance test there is no special place, is under atmospheric pressure by the waterproof connector to connect into the water after four hours, take out after check the waterproof connector inside there is no water seepage phenomenon, if there is water seepage phenomenon is considered unqualified, the waterproof performance testing of qualified products will be the first two tests again, if not meet the requirements should also be regarded as not qualified.


The service life of the waterproof connector mechanical test is to contact a continuous plug three thousand times or so later viewing contact friction surface have serious wear and tear, can allow a slight surface friction damage, but not allowed to affect the mechanical performance, once appear, the influence is regarded as the service life of the product is unqualified, unqualified products will not be selling into the market.
