After the connector has passed the European Union (EU) ROHS certification

For most manufacturers, if you want your products to be recognized by customers, in addition to the excellent quality, if they can pass some qualification certifications, then the sales of the products may have unexpected effects. Konnra connector engineers will take you to know the relevant knowledge of European Union (EU) RoHS certification. Konnra engineers pointed out that RoHS was promulgated in the European Union (EU) in February 2003. This EU regulation aims to restrict the use of hazardous substances in electrical and electronic equipment (EEE). Among the prohibited substances, perhaps the most widely known is Lead (Pb) too. Later, RoHS certification gradually formed a standard specification in the connector industry. After the products produced by manufacturers conform to these specifications, product sales are bound to be broken.

The Restriction of Hazardous Substances Directive (RoHS) and the Registration, Evaluation, Authorization and Restriction of Chemical Substances (REACH) have some similarities, including some prohibited substances, but their implementation and covered products are different. RoHS is a directive for electronic products. Therefore, each country in the European Union (EU) is responsible for the implementation of RoHS and fines for any products that violate the directive. However, REACH is a regulation covering all products, regulated by ECHA, and the enforcement and penalties are the same throughout the EU. In addition, RoHS currently has 10 substances, while REACH has 181 substances.
In 2017, it passed the RoHS 2 certification and added four substances, bringing the list to ten. For these four other substances, no exemption was granted. According to this regulation, for most connector manufacturers, these added phthalates are easily accepted because they have become part of REACH.
The complete list of substances is: lead (Pb), RoHS logo, mercury (Hg), cadmium (Cd), hexavalent chromium (Cr 6 ), polybrominated biphenyls (PBB), polybrominated diphenyl ethers (PBDE) phthalate (2-ethylhexyl), ester (DEHP), benzyl butyl phthalate (BBP), dibutyl phthalate (DBP), diisobutyl phthalate (DIBP).

From the perspective that connectors need to comply with ROHS specifications, product conformity assessment (COC) may not be all that customers want to see. In many cases, customers prefer to view third-party test reports, especially SGS reports. . There are generally two types of tests that can be used to prove compliance with RoHS requirements, namely non-destructive X-ray fluorescence (XRF) and wet chemical analysis. Wet chemical analysis is more accurate in these two measurement types. Overall, RoHS-certified connector products allow customers to use them with confidence and ensure product safety and reliability.

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
