Through the versatile interface of this adapter, users do not need to have multiple wires when using a variety of devices, ranging from slim handheld devices to rugged industrial applications. The newly introduced C-type USB adapter's socket housing enhances EMI (electromagnetic annoyance) shielding function, helping to eliminate unnecessary EMI leakage and providing users with better functions than traditional products of the same type. In addition, the C-type USB adapter provides greater adhesion to the adapter plate compared to industry-standard packages, increasing reliability and ruggedness.
Basic performance
The basic performance of connectors can be divided into three categories: mechanical, electrical, and environmental.
Mechanical behavior
Mechanical properties In terms of the connection function, the insertion force is an important mechanical property. The insertion force is divided into the insertion force and the extraction force (the extraction force is also called the separation force), and the requirements of the two are different. There are maximum insertion force and minimum separation force regulations in the relevant standards, which indicates that the insertion force is small from the point of view of use (thereby having a low insertion force LIF and a structure without ZIF insertion), and if the separation force is too small, It will affect the reliability of the contact.
Another important mechanical property is the mechanical life of the connector. Mechanical life is actually an indicator of durability, which is called mechanical operation in GB5095. It is a cycle of one insertion and one extraction to determine whether the connector can normally complete its connection function (such as contact resistance value) after the specified insertion and removal cycle. The insertion and extraction force and mechanical life of the connector are related to the coating quality (sliding friction coefficient) of the contact structure (positive pressure) and the dimensional accuracy (alignment) of the contact arrangement.
Electrical performance
The main electrical properties of electrical performance connectors include contact resistance, insulation resistance and electrical strength.
1 Contact resistance High quality electrical connectors should have low and stable contact resistance. The contact resistance of the connector ranges from a few milliohms to tens of milliohms.
2 Insulation resistance is an indicator of the insulation properties between electrical connector contacts and between the contacts and the casing, in the order of hundreds of megaohms to several gigaohms.
3 Resistance to electric strength, or withstand voltage, dielectric withstand voltage, is the ability to characterize the rated test voltage between the connector contacts or between the contacts and the casing.
Environmental performance
Environmental performance Common environmental properties include temperature resistance, moisture resistance, salt spray resistance, vibration and shock.
1 Temperature resistance The current maximum operating temperature of the connector is 200 ° C (except for a few high temperature special connectors), the lowest temperature is -65 ° C. Since the current generates heat at the contact point when the connector is in operation, resulting in a temperature rise, it is generally considered that the operating temperature should be equal to the sum of the ambient temperature and the junction temperature rise. In some specifications, the maximum allowable rise of the connector at rated operating current is specified.
2 Intrusion of moisture-resistant moisture will affect the insulation performance of the joint h and corrode metal parts. Constant damp heat test conditions are relative humidity of 90% to 95% (up to 98% according to product specifications), temperature +40 ± 20 ° C, test time according to product regulations, at least 96 hours. The alternating heat and humidity test is more stringent.
According to previous reports, Apple may update the iPhone's charger this year. The interface of the original charging head will be updated from the normal USB-A interface to the USB-C interface, and the mobile phone will still be Lightning. At the same time, more importantly, the new charger will support fast charging, power up to 18W. Today, there is news that Apple will have to abandon the lightning interface next year, and the iPhone will be equipped with a USB-C interface.
The news comes from the supply chain authoritative media Digitimes, who said in the report that next year, that is, the iPhone in 2019 will be equipped with a USB-C interface, which will be a major shift in the product line, and will also announce the mission of the Lightning interface. End.
Apple has always had the habit of using a dedicated interface. Since 2007, the iPhone has inherited the 30-pin interface of the iPod. Until the iPhone 5 in 2012, they replaced the iPhone interface with Lightning. At the time, this practice caused objections from users. It was not that Apple did not support the USB interface, but instead switched to the new interface, so that their 30-pin old data lines could not be used.
First, the connector products began in the Second World War, mainly used in military enterprises. With the end of World War II, the world economy began to transform into the people's livelihood, the application of connectors has been extended to various fields, now let us briefly understand the connector Mileage!
Second, the connector products began during the Second World War in 1939. After the war, with the development of consumer electronics products such as TV and telephone, the connectors were rapidly expanded from early military applications to general consumer electronics, automobiles and computers. And other information fields.
Third, the development of China's connector industry is also closely related to military use. From the embryonic stage of the 1940s, the United States invested in the production of military connectors in China to equip the Chinese army in the war. In 1949, the US capital retreated and some of the technical equipment was left behind, which formed the prototype of the development of China's connector industry in the future.
IV. From 1950 to 1970, in the initial stage of development, China formed a public-private partnership with private enterprises and related enterprises before the war, and established various subordinate factories and local state-owned factories, collective factories, such as 769, 851, and eight. Wu 0 Factory, 117 Factory, Zhenjiang Connector Factory, Beijing Radio Components 9 Factory, Shanghai Radio 9 Factory, etc. The main applications of the connectors produced at this time are related to the military industry, aerospace industry.
5. In the 1980s, China implemented the policy of reform and opening up, and began to switch to the production of consumer electronics products. At this time, China continued to carry out economic reforms and opened up to the outside world. Many foreign investors entered the mainland market to invest. In 1987, Japan's First Electronics Co., Ltd. and Shenzhen SEG Electronics Group, together with the Radio 9 Factory, established the earliest foreign joint venture. After the 1990s, encouraged by the mainland's various foreign investment policies and incentives, connector manufacturers around the world almost transferred their production bases to China's hot land, including the largest world-class connector manufacturers, such as: AMP, Amphenol, etc. all invested in China in 1992. At the same time, many other foreign companies in the 1980s, with the rise of the personal computer industry, connector manufacturers such as JST, KET, JAM, FCI and other manufacturers, in addition, Taiwan Kang Xu, Taiwan Anpu, Taiwan Aviation Electronics International giants have also come to the mainland to invest.
Sixth, like the Taiwan connector industry is also in the beginning stage in the 1970s, the main manufacturers such as Xinsheng Seiko, Liangwei, Ruifang Electronics, Xinyin, Zhijia, etc., mostly to produce power outlets, plugs or wiring harnesses, etc. The order of products is mainly based on the size of the company. Even DuPont has set up factories in China to produce connectors. They bring advanced machinery and equipment and a relatively large-scale production system. It can be said to be a pioneer in the connector industry.
7. Around 1993, with the enthusiasm of the computer factory in China and the consideration of cost reduction, foreign connector manufacturers have gone to China to set up factories, so that the connector industry has developed rapidly! Not only do connector manufacturers in Taiwan, Hong Kong, Japan and Europe strengthen their investment in China, but the output value of China's connectors is increasing day by day, and the production scale of China's connector industry also provides customers in various industries around the world.
Nowadays, the company that mainly deals with Japanese HRS, JST and US TE/AMP, JAE, FCI and other world brand connectors is Dongguan Qingda Electronics. Like circular connectors, rectangular connectors, FFC/FPC connectors, aviation plugs, board-to-wire connectors, wire-to-wire connectors, board-to-board connectors, etc. If you need it, please feel free to place an order for purchase. If you want to consult, you can also directly contact Baidu Qiao's Hougong, professional technology, to answer your problems for your factory or company, or for your products. Stereotype, saving you time, allowing you to confirm the model faster and put it into production and processing.
The color of the gold layer is not normal. The color of the gold plating layer of the connector is inconsistent with the color of the normal gold layer, or the color of the gold layer of different parts in the same accessory product is different. The reason for this problem is:
1. Influence of impurities on gold plating raw materials
When the impurities introduced into the plating solution exceed the tolerance of the gold plating solution, the color and brightness of the gold layer will be affected quickly. If it is affected by organic impurities, the gold layer will appear dark and faint. The film is dark and the position of the hair is not fixed. If the metal impurities interfere, the effective range of current density will be narrowed. The Haoer cell test shows that the current density of the test piece is not bright at the low end or the high-end plating is not bright and the low end is not plated. Reflected on the plated parts, the coating is red or even black, and the color change in the holes is more obvious.
2, gold plating current density is too large
Since the total area of the plated parts is incorrectly calculated, the value is larger than the actual surface area, so that the amount of gold plating current is too large, or the amplitude of the gold plating is too small when the plated gold is used, so that all or part of the gold plating in the groove is crystallized, and the gold is visually observed. The layer is red.
Automotive connectors are the largest application market. According to statistics, the automotive market application is the largest application mayor of the global connector, accounting for 22.2%. Followed by telecommunications and data communications, about 21%, in addition to computer and industry accounted for 16%, 12%. The automotive sector is expected to open up new growth spaces. The innovation of automobiles is mainly in automotive electronics. With the popularity of new energy vehicles, ADAS, driverless and vehicle networking in the future, the proportion of automotive electronics will continue to increase. According to the data, the global automotive electronics scale is expected to reach US$234.8 billion in 2016, with a compound growth rate of 9.8% in 2012-2016. Among them, the size of China's automotive electronics market is expected to be 74.06 billion US dollars, with a compound growth rate of 14.6% over the same period. The strong growth of automotive electronics will drive the penetration rate to increase. It is expected that by 2020, the penetration rate of automotive electronics will increase from 30% at this stage to over 50%.
Automotive connectors target the vast market for electric vehicles. Compared with the mobile phone industry chain, the automotive industry chain is more closed, including TE, Molex and other occupying the leading position of automotive connectors, and domestic connector manufacturers are relatively difficult to enter. In 2015, China's electric vehicle (EV) sales increased by 449% (including passenger and commercial vehicles), and plug-in hybrid vehicles (PHEV) sales also increased by 181%. The main increase in the future automotive industry comes from new energy vehicles. The sales of traditional energy vehicles have gradually declined.
Nowadays, there are so many electronic brands on the market, and the mobile phone brands are even more numerous. In the past, different models of mobile phones of different brands were different, and the models of mobile phone accessories equipped were also varied. Often this brand of mobile phones is not compatible with other brands of accessories. The case of the mobile phone accessories "special machine-specific" can certainly guarantee the uniqueness of the brand's technology, and it also causes a lot of trouble for the user.
Take the charger as an example. Nowadays, mobile phones such as Apple and Huawei are generally used in the market. Because of the different brand backgrounds, the technologies used are different. This has led to the emergence of a wide range of goods in the mobile phone charger market. And they are not universal with each other, causing consumers to not be able to charge in time in certain special emergency situations, such as when the mobile phone battery needs to be charged.
Mobile phone chargers cannot be used across brands, which is a very inconvenient thing for consumers. Is there any way to solve this problem now?
The answer, of course, is there!
We only need a TypeC data transmission line to solve this problem.
