The miniaturization, wireless, high-speed and intelligent HDMI connectors are the trend of the times. At present, the global connector industry is at the starting point of a new round of creative demand represented by 5G and new energy vehicles. In terms of new energy and technology, four typical electric vehicle systems - high power density battery pack, battery charger, inverter and DC-DC controller system have added a lot of connector content, and the pace of automobile electronization is also accelerating and popularizing. With the continuous improvement of core system technologies such as supply side battery, the medium-term increase of production capacity, the stimulation of demand side policies, and the transformation of consumer demand preferences, etc. The field of new energy vehicles may be entering the starting point of creative demand.

In the long run, the manufacturing, sales and management costs of HDMI connector industry are high and stable, and profits are vulnerable to price erosion. The upstream of the connector industry is raw materials such as plastics and precious metals. The price fluctuation has a certain impact on the manufacturing cost. The labor cost required for processing is high, which is one of the main reasons for manufacturers to transfer the industrial chain to Asia where the production cost is low. According to the report, excluding the impact of the financial crisis in 2009, the industry cost of sales (COGS) averaged 71.2% of sales from 2004 to 2013. The decrease in sales price in 2009 did not cause the same decrease in sales cost, resulting in the proportion of sales cost to sales as high as 77.5%. At the same time, the average sales, general and administrative expenses of the industry from 2004 to 2013 accounted for 15.5% on average, and rose in fluctuations. In order to help enterprises survive the financial crisis, the connector industry raised prices in 2010, and the sales growth picked up significantly that year. However, in most years, the change direction of price change rate is opposite to that of sales growth rate, which reflects that the price of connector project is low under competitive pressure, but the overall market demand elasticity is large, leading to an increase in total sales.

During the driving process of the car, all parts of the car need to work, and each part must closely cooperate. The car HDMI connector plays a very important role in the cooperation of all parts of the car. Whether it is a traditional vehicle or a new energy vehicle, the connector has always been valued by automotive industry engineers. In the analysis of some traffic accidents, it is found that many traffic accidents are caused by connector failures.

From the perspective of the use purpose of automobile HDMI connector, in order to ensure better driving of the automobile, the reliability of the connector can be divided into the sealing performance of the connector in use and the fire resistance performance of the automobile in driving. In addition, the connector can also show shielding performance and temperature control performance during vehicle driving.

Generally speaking, when discussing the sealing performance of automobile HDMI connector, it is not only about the sealing performance of water in automobile. In this field, IP67 is an internationally popular management standard. Although different parts of the vehicle have different waterproof requirements, many automobile manufacturers will choose IP67 to ensure the sealing performance of their automobile HDMI connectors. The power supply is a very important energy source in automobile driving, which not only relates to the normal work of the engine, but also often involves the use of the power supply in the driving process. Therefore, in the automobile power supply system, the automobile connector has different division. Some sealing measures can be taken between male connector and equipment, between male connector and cable, between male connector and female connector, and between female connector and cable.
