In general, a connector is an element of two different circuits that acts as an AC transmission bridge for current or signals between them. Widely used in the electronics industry. However, there are also some problems in the application process. For example, in those humid places with high water content, traditional connectors can not be used and have poor performance. What should we do at this time? Gradually, the waterproof connector was born, which is not much different from other connectors in essence, but has waterproof function.
In our daily life, there are many kinds of waterproof connectors. What performance underpins the market for waterproof connectors? It comes from three points, namely, the mechanical performance, electrical performance and environmental performance of the waterproof connector. This is his advantage in maintaining the market and the key to stand out among similar products.
What are the performance advantages of waterproof connectors?
The first is the temperature resistance of the waterproof connector. Today's waterproof connectors are well adapted to both high and low temperatures. Up to 200 degrees Celsius (except for a few special waterproof joints for high temperature) and as low as minus 65 degrees Celsius. As we all know, due to the existence of resistance, the equipment will generate a lot of heat in the working state of current, resulting in the final temperature rise of the equipment. So we often say that the temperature includes the sum of ambient temperature and contact temperature.Because we will indicate the maximum temperature allowed under the rated working current of the waterproof connector, the user can better combine the actual situation.
The second point is that the waterproof connector can effectively meet the salt-resistant environment. Surface treatment layers of common metal structures and contacts may cause electrochemical corrosion. While we cannot prevent salt and moisture in the work environment, we can improve the performance of waterproof connectors to avoid corrosion of the equipment in this case.So we will do some smoke experiments to test the performance of the product, including compressing air with a specified concentration of NaCl solution to create a smoky atmosphere for the equipment. Ordinary waterproof joint can reach more than 48 hours (standard value).
The third is vibration and shock resistance: vibration and shock resistance is also an important parameter for the performance of waterproof connectors. These two values will become more and more important in special cases, including aviation, aerospace, railway and road transportation. These two values are the weights for testing the soundness, electrical contact and soundness of the waterproof connector. The acceleration, peak duration and time, and electrical connections of the pulse waveform are typically specified in the impact test.
