How to test the performance of waterproof connectors?

Connector is used to connect the power supply of large electrical equipment in our daily life as well as in the production of enterprises as a kind of connecting equipment, and it is an indispensable product to connect the electrical appliances in every large-scale enterprise. And waterproof connector is further than the traditional connector, it is not only has the traditional connector connection function and also has the traditional connector does not have the waterproof function. Our consumers must not underestimate the waterproof function, the waterproof connector waterproof function in the actual application of the enterprise can indirectly bring a lot of profit it. It can indirectly bring a lot of profit to the enterprise refers to its waterproof function in the actual application for the enterprise's large electrical appliances to bring the safety, the safety of the enterprise electrical appliances have guaranteed after the peace of mind to carry out production activities. In the past, the connector does not have waterproof function, if once the connector into the water that is not the connector will be damaged, but the entire electrical appliances in use may be damaged as a result of the machine is damaged, the enterprise can not carry out the production will be directly to the enterprise to bring economic losses. So we say that the waterproof connector indirectly for the enterprise to bring a lot of profit. But the waterproof connector has such a good waterproof effect is not by chance, but after a rigorous performance test, now to tell you about the waterproof connector performance test requirements.

Waterproof connector general waterproof connector test to be divided into a number of steps, respectively, to be tested are: waterproof connector electrical strength, insulation resistance, salt spray test, waterproof performance, mechanical service life and interoperability. These are a waterproof connector in the manufacture of successful performance tests to be accepted, these tests are a waterproof connector can be qualified to leave the factory must go through the program. Waterproof connector resistance test at room temperature, between the conductor and insulator test voltage AC1500V/50HZ after one minute after there is no breakdown or flying arc and other phenomena, and also in the test time to check its ultra-leakage current is not less than 2mA, less than this value is a qualified product. Insulation resistance test method is similar to the resistance to electricity, only the test voltage is changed to DC500V test can be. Salt spray test to carry out certain preparatory work, first of all, to prepare some salt concentration of five percent of sodium chloride solution, so that the waterproof connector in this solution after 48 hours of immersion, to see the waterproof connector if there is a corrosion affecting the performance of the connector is considered unqualified, if there is no corrosion affecting the performance is qualified. Waterproof performance test there is no special place, is at room temperature and pressure by the waterproof connector to connect well into the water after 4 hours or so, take it out after checking the waterproof connector inside there is no water seepage phenomenon occurs, if there is water seepage phenomenon occurs is regarded as unqualified, in the waterproof performance test in the qualified products should be carried out again in the first two tests, if it does not meet the requirements are also to be regarded as Failed. Mechanical service life of the waterproof connector test is to put the contact pieces of continuous insertion and removal of about three thousand times to see the contact pieces of the friction surface there is no more serious wear and tear, can be allowed to appear a slight surface friction damage, but does not allow the emergence of the situation affecting the performance of the mechanical use of the product is considered to be unqualified once the situation affecting the mechanical service life of the product is considered to be unqualified, the unqualified products will not be Put on the market for sale.
