The waterproof connector is the same as the cable connector in the electrical industry, So what’s the difference between the waterproof connector and cable connectors?the waterproof connectors can not only be waterproof and also conductive, They can be used in water environment,Like the LED light,lighthouse in the rain,the ship and yacht in the river,the industrial equipment need to be sprayed,the fire fighting truck in emergency etc,They all need waterproof connectors,This is the most important difference between waterproof connectors and cable connectors ,Also the unique characters of waterproof connectors.

With the development of the market,Now,The work environment ,device,equipment,with water is more and more popular,and more people choose waterproof connectors ,The waterproof connector has excellent sealing performance,Safe and reliable quality waterproof connector have great demand in the market,So the quality standard is higher,  The waterproof and dustproof class of waterproof connector products reaches IP68 standard,In other words,Put the connectors into the 10 meters deep water,let them work 12 hours,When the shell dip to 15 degrees,The liquid poured into the connectors have no influence,Put them into the the 100 deep water,breaking test for 12 hours,The liquid pour into the shell make no influence,still remain good performance,Only up to this requirement,They can be called qualified waterproof connectors.

Waterproof connector is excellent products which is widely known. They are used in many areas.So what is the performance of them to support their market?they are mechanical property,electrical performance and environmental performance,which help them to keep the advantage of the market and made them stand out form the similar products.

First.The heat resistance.Today,The waterproof connector have good adaptability in both high temperature and low temperature.The highest temperature can up to 200℃(except few high temperature special waterproof connectors )The lowest temperature can be as low as -65℃.As is known to all. Because of the resistance,The equipment will produce many heat under the working condition of the electricity.cause the equipment heat up then.So the temperature we usually mentioned is consisted of environment temperature and contact temperature.We’ll show the highest temperature limits of the waterproof connector under the rated operational current.

Secondly.The waterproof connector can effectively adapt to the environment of salt spray resistance.General structural metal ,Contact surface may have electrochemical corrosion.Though we can’t avoid the working environment with salty and moisturity.We can improve the performance of the waterproof connectors to prevent the equipment are corroded.We test the performance of the connectors by smoke test .including we create Smoke atmosphere by use a certain concentration of NACl to compressed the air,General waterproof connectors can be up to 48 hours.

Thirdly.Vibration resistance and shock resistance are the vital parameter of the waterproof connectors.These two parameters are especially important in special environment.including aviation ,spaceflight,railway,road transportation etc.These two parameters are the measuring ruler of the sturdiness and electric contact property.Usually in the impact experiment.The peak acceleration,time of duration and the time of impact pulsation waveform and electrical connectivity interruption.

Fourthly.The humidity of the environment.For waterproof connector to power supply.Somehow.The humidity may have impact of the waterproof connectors. But the AnPuLun waterproof connectors reduce this value to the least.General product are not influenced among the moderation 90%-95% .

Electrical Performance is the essential performance of waterproof connectors.In general.They include contact resistance,insulation resistance,dielectric strength etc.

The order of magnitudes of insulation resistance are hundreds of megohm to thousands of megohm.The contact resistance is from a few milliohms to tens of milliohms.The dielectric strength is the ability to withstand rated test voltage between the waterproof connector contacts or between the contact and the enclosure.which is generally can up to the standard value.

Lastly.The mechanical property of the waterproof connectors.including the lifetime of the waterproof connectors which is a vital index.It’s a good experience when using a good performance and long lifetime waterproof connectors. The waterproof connectors of Dongguan Dosin Hardware Electronics Co., Ltd can be used for a long time.

In the past few years. China’s society and economic information is developing rapidly.The demand for high-end electronic equipment is booming.Connector foreign-funded enterprises are increasing.In order to improve the ability of  competition,China’s connector industry should actively strengthen the development of high-end miniature connectors.For China’s miniature connectors just get start with poor technical foundation and shortage of funds.We believe that the following counter measures should be taken.

  • Establish economies of scale and group

The development of modern high-density micro connectors will not work,If there is no certain scale economy .Therefore, the current industrial pattern of repetition, Dispersion and small production should be led to the joint and gradually realize joint investment, intensive management.In accordance with the requirements of the modern enterprise system to establish a large group of companies with world-class competition to compete with foreign great competitors group.

  • Pay attention to the investment of technology and talents

We must base on the progress of technology and optimize technical structure, intensify technological upgrading,Strengthening the renewal of technological equipment,Introduce advanced technology of high density connector from abroad,At the same time.We need to strengthen the ability of digestion and absorption.enhance the ability of independent development,We should also pay attention to the cultivation and utilization of talents and fully mobilize the enthusiasm of scientific and technological personnel.

  • Products must strive for the grade.

We need to improve product quality in an all aspects.Widely adopted international standards.Strive to develop high-tech and cutting-edge high-reliability products.Create, excellent, special products.Focus on high-tech key technologies such as SMT.The main direction of the production of high and mid-range micro connectors.drive the overall level of improvement.

  • Identify key service areas

The development of micro-connectors must first meet the needs of the national economy, national key projects and military assembly.We should attache importance to investment equipment and a new generation of complete machine products.In particular, we must focus on promoting the national economy information service. Such as financial management computer networking, etc.In order to change the situation of mainly in consumer middle and low-end products and low localization rate of investment products.Our final purpose is gradually replacing imports with localization.

  • Face international and domestic markets

We need to establish a big market concept.participate in international competition and widely adopt international standards with international standards.According to market demand,While meeting domestic support strengthen export awareness and increase export share.We should strive to carry out the construction of foreign sales services.expand the international market share of high-end miniature connectors.

The world’s micro connector market and technology are moving forward.and thus driving the overall improvement of China’s high-end connector production capacity,Facing opportunities and working hard.The development of China’s micro connectors will certainly make substantial progress.Gradually we’ll narrow the gap with advanced countries and make China a powerful power producer.
