Reasons for the difference in connector plating quality

图片
In order to ensure the quality of the gold-plated layer, connector manufacturers often repeatedly study the problems that may occur in the quality of gold-plating technology. Regarding the color of the gold-plated layer of the connector of the connector is different from the normal gold-plated color, and the gold-plated layer in the same product is significantly different The problems have been explained, and the basic mountains can be summarized into the following 4 reasons: ​ The effect of impurities in gold plating raw materials. When the gold plating process is performed, the impurities brought in by the plating solution's chemical materials will exceed the gold plating solution's use standard and will soon affect the color and brightness of the gold layer. The phenomenon of darkening and flowering of the cash layer or the interference of metal impurities will cause the effective range of the current density to be narrowed, which will show that the low end of the curre...

Common problems in RF circuit design

In the actual circuit design, you will encounter various strange problems, which requires you to accumulate experience through practice. The really practical trick is how to deal with these guidelines and rules when they cannot be accurately implemented due to various design constraints. Of course, there are many important RF design topics worth discussing, including impedance and impedance matching, insulation materials and laminates, wavelengths and standing waves, etc. Careful planning under the premise of comprehensive understanding of various design principles is a guarantee of successful one-time design . 1.Interference between digital circuit modules and analog circuit modules If the analog (RF) and digital circuits work separately, they may each work well. However, if the digital signal cannot be well separated from the RF signal. Weak radio frequency signals may be damaged. As a result, the performance of wireless devices will deteriorate, or even they will not work at ...

What are the connection methods of the power connector

图片
The power connector is a component of plug and socket that provides current transportation for electronic equipment. When we use the power connector, we should choose the connector and cable termination method reasonably. The top ten are very important. Today, I will share with you the three connection methods of the power connector. 1. Crimping: The crimping connection should be able to cause the wires and contacts to produce metal-soluble flow and symmetrical deformation of the material. Similar to cold welding, it can obtain better mechanical strength and electrical continuity, and can withstand more severe environmental conditions . At present, it is generally believed that the correct crimping connection arm is good for soldering, especially in high current applications, crimping must be used. 2. Soldering: The most common connection is soldering. The most important thing for a solder connection is that metal continuity should form between the solder and the surface being s...

Common connection methods of industrial connectors

Conventional connected devices show customers many years of service promises in the natural environment of a typical corporate office. As everyone knows, exposing the same copper cable or fiber optic connector to extreme standards has reduced its characteristics and credibility. End users must pay expensive maintenance fees for fault detection and replacement of spare parts. A new type of RF connector, which is professionally designed to build a strong Ethernet interface connection in extreme natural environments. It is more robust, robust and resistant than previous RF connectors. This new socket is widely regarded as an "industrial connector" and its use is not limited to the processing industry. This type of RF connector is designed to withstand the rigors of the more extreme natural environment of industrial production. Bolt connection It is a traditional interface method, which is relatively rare nowadays. It will be effective in some large-scale component compone...

OBDII connector in the era of big data

Car networking uses cars as information terminals, integrates various types of sensors, establishes interconnection of many different types of communications, and realizes the seamless connection of perception and communication, enabling the information of on-board units and road monitoring systems, traffic management systems, logistics systems, and parking. The garage system, auto repair, auto rescue and other automobile 4S shop service systems, insurance systems, road medical rescue systems, and daily life-related value-added services combine to form a powerful automobile Internet. Achieve vehicle-to-vehicle (V2V), vehicle-to-road (V2R), vehicle-to-network (V2I), vehicle-to-person (V2H), and other interoperability, and realize vehicle communication and roaming between heterogeneous networks In order to ensure the real-time, serviceability and network in terms of functions and performance, the unity of public and private networks is formed. The rise of the OBD model has mainly fo...

Impact of Smart IoT Automation on Connectors

图片
The industrial industry has transitioned from mechanical control to electronic control, and now we are in the middle of digital transformation. According to the analysis of the connector market survey report, the rise of the smart city, smart grid, smart factory, and smart IoT automation markets affects the development prospects of industrial connectors. Connectors designed for the industrial market come in a variety of shapes and sizes and are subject to a variety of standards and specifications, depending on the type of application and end use. These applications typically include industrial "factory-shop" environments, but also include power generation and distribution, machinery, mining, geophysical exploration and heavy construction, and agricultural equipment. Industrial connectors can be divided into two basic categories. On the one hand, there are connectors (round and rectangular) as defined by military specifications. In essence, these interconnections can re...

How to judge the problems in harness processing

图片
There is a noticeable break between the cable and the cable end, which may cause the cable to break. The outer insulation and cable termination may be complete, but the inner cable and cable termination of the cable may break, which may happen. Harness cable guides and cable terminations are tensile tested. During the tensile test, if the insulation layer of the cable gradually narrows, you can confirm that the cable has broken; When the ordinary wiring harness has a poor contact problem, the connector is likely to have a problem. When opening the electrical equipment, touch or pull the corresponding connector of the electrical equipment and determine by touch that when the connector is installed, the operation of the electrical equipment is normal and abnormal, which means that the connector is not well tested; The outer insulation and cable lugs of some cable harnesses are intact, but the inner core cable and cable connector have been broken, which may cause the cable to break...

Harness Processing Manufacturing Upgrade

In the context of global environmental conservation, new energy vehicles have become an inevitable trend in the development of automobiles worldwide. PwC's first blueprint for the Chinese auto industry, released on December 8, states that China's new energy vehicle sales are far ahead of other markets in the world. With the government's vigorous support for new energy vehicles, China's new energy vehicle era has arrived. Global sales of new energy vehicles reached 500,000 in 2015, of which 330,000 were sold in China, three times the previous year, and far ahead of other markets in the world. Accelerating development, Internet giants and other emerging players are actively entering the market, bringing pressure and shock to traditional car manufacturers and dealers. There is no doubt that new energy and intelligent connected cars have become the mainstream of the automotive industry, and the demand for applicable wiring harnesses will also increase significantly.
