China's connector market has the most potential for development
According to a report released by Bishop and Associates , a connector market analysis company, although connector sales volume continued to increase in the last two quarters of 2009 , the global connector market fell by about 25% in 2009 due to the overall market downturn. Among them, the demand for connectors from medical and military / aerospace OEMs has dropped by 5–7% . In addition, the price of connectors also appeared weak, falling by 5% . Low demand and excess capacity are major factors in connector price declines.
However, as current connector manufacturers are actively adjusting their inventory, and with the rapid growth of the consumer electronics, automotive electronics and communications terminal markets, the global connector market will still have great potential for development in the next three years. According to the forecast of the China Electronic Component Industry Association Information Center, by 2010 , the global connector production will reach 46.8 billion, and the market size will reach 51.5 billion yuan, with an average annual growth rate of 17% and 15% respectively .
At the same time, Asia has become the most promising market for connectors. Global Industry 's report shows that the Asian market will reach US$ 6.4 billion in 2010 , and China will become the world’s fastest growing and largest capacity connector market. It is estimated that by 2010 , China's connector market capacity will reach 25.7 billion yuan, and the future growth rate of China's connector market will continue to exceed the global average.
According to an online survey conducted by the "International Business Intelligence" website, the market demand for USB 2.0/3.0 , HDMI1.3/1.4 and 10G Ethernet connectors is expected to be the largest in 2010 .
USB 2.0/3.0 With the ever-increasing demand for connection bandwidth, the 480 mbps transfer speed of USB 2.0 has been insufficient to meet current and future application requirements. The introduction of the USB3.0 standard means that the USB interface is about to welcome another generation. USB3.0 supports a transfer rate of about 5Gbps , which is a big step forward in terms of transmission speed, power management, and flexibility. The industry generally predicts that by mid- 2010 , USB3.0 will usher in huge opportunities in applications such as mobile phones and portable Internet terminals.
Naked terminal high temperature there are two possible: loose terminal contact resistance is too large, thus overheating;Terminal is not loose, but circuit and over current fever for some unknown reason, such as power supply voltage is too high, short circuit or load.
1. The voltage is too high can check up from the source, the transformer secondary voltage distribution box - voltage to the voltage electrical equipment.Socket button can also be assembled and locked.Assembly button bits can be more firmly fixed on the PCB, lock button to lock the mother after the installation is completed and socket.All kinds of socket design can match different maternal insertion method, for example: horizontal, vertical or inclined to printed circuit boards, etc.Can choose metric gauge can also choose to standard gauge.
2. The ground fault can also be looked up from the transformer, distribution box and then to the ground.The grounding to earth and normal earthing fault line should be ruled out.Can use insulation table or shaking table is cut to measure, subsection measurements, as far as possible only piecewise measuring cable, wire, circuit breaker, switch power supply circuit, it would be very difficult for us to block the case, then pulled out a fuse of the weak current equipment, sensing equipment.
Grounding the key lies in the lower ground resistance, at the same time, contact area.The former can ensure that the ground has a close to the ground potential of zero potential as low as possible, which can ensure there is enough capacity to provide a fault current channel, including lightning or short circuit fault, and so on.
