What is the role of connector plating

People who often buy connectors, carefully observe the plating indicator on the connector. We will find that the alignment may be small and not very beautiful, but it is this arrangement that is not very beautiful, but it is the most important of any connector. One of the components. However, it is not a difficult thing to make the appearance of the connection better. Some of us can plate the connection, so that it can be a good replacement. So what is the role of electroplating the connector plating? Konnra connector engineer will come to you to popularize the effect of electroplating the connector connection plating.
Terminals with gold plated
Konnra connector engineers pointed out that electroplating is the process of depositing another layer of metal on another metal. Simply put, it is achieved by using a series connection and a liquid solution containing the plating material. What are the benefits of the plating process?
Connector conductor plating has many effects. A good connection of the plating layer can ensure the best conductivity of the circuit. When the basic material of the connection is conductive, the plating will reduce the resistance of the interconnect itself, which makes it easier for current to flow through the connection.
The electroplating process of the connector conductor can achieve mechanical purposes. Rubbing two metals will cause friction and damage, and a layer of plating can protect the underlying metal inserted below. For many reasons, gold is often replaced by electroplating materials, which has excellent electrical conductivity, and gold is also a precious metal and does not react with other materials, which makes it very suitable for contact plating. Because gold does not oxidize or change color in the atmosphere, it has long-term durability in harsh environments.
Terminal with Tin plated

From the point of view of manufacturing cost, tin can sometimes replace gold. Although tin is not as wear-resistant as gold alloy, it also has the advantage of good combination with solder, which is very suitable for use on printed circuit boards (PCB). In fact, in order to combine the quality of gold and tin, the two are often plated, and the mating area of the connection is plated with gold to provide the best mating surface. The terminals are tinned to provide the best connection when soldering to the PCB. This process is called selective plating.

What is the coaxial connector?

图片
Coaxial connectors are used to transmit RF signals. They have a wide transmission frequency of up to 18 GHz or higher and are mainly used for radar, communication, data transmission and aerospace equipment. The basic structure of the coaxial connector includes: a center conductor (a positive or negative center contact); a dielectric material outside the inner conductor, or an insulator, and the outermost is an outer contact, which serves as a shield outside the coaxial cable. The same function of the layer, that is, the signal transmission, the grounding element as a shield or circuit. The coaxial connectors are mainly divided into: SMA, SMB, BNC, TNC, SMC, N-type, BMA, and the like. Male: Male (plug), thread inside, inside is the needle. Such as TNC (M). Female: Female (socket), threaded outside, inside is a hole. Such as SMA (F). RP: Reverse Polarity means that the head and the inside of the needle are opposite. Bulkhead: It is the joint of the lockable screw on the board and

Talking about the function, classification and working principle of OTG data line

图片
  What is the OTG line? OTG is mainly applied to the connection between various devices or mobile devices for data exchange. The development of USB technology enables computers and peripheral mobile devices to transmit various data through simple USB connections. This will lead to a situation, once the mobile phone or tablet does not have a computer, we cannot manage the data of mobile devices such as mobile phones, which brings inconvenience to users. As mobile devices such as mobile phones become more and more like computers, can we imagine that we can use mobile phones as computers? Can a U disk, USB network card, etc. be connected to the phone? The answer is yes, the OTG function is to realize that the mobile phone can be connected with USB devices such as U disk, but the mobile phone has a tiny   USB   interface, which cannot meet the needs of USB ports such as U disk. So far, the OTG data cable came into being. The role of OTG is to realize data transfer between mobile devices wi

Calculation method of wire diameter of automobile wiring harness

图片
  When using the CATIA module for wire harness data production, the wire harness segment diameter is written into the software as an important parameter. All subsequent clearance checks and motion analysis are based on this value. Therefore, if there is a big difference from the actual situation, it will inevitably lead to the original requirement of meeting the safety gap, and it will be found to have interfered when the vehicle is actually installed, or even cannot be assembled. Konnra wiring harness  engineers provide you with a theoretical calculation method (wire harness standard algorithm) for estimating the outer diameter of automotive wiring harnesses. A wire harness segment is a collection that binds all wires together with tape or other wrapping. Taking into account that the tape is only wound on the wire harness, and the wrapping of casings such as corrugated pipes also needs to determine the outer diameter of the wire harness before selection. Therefore, when calculating, w
