RJ-11 connector

I do n’t know how much you know about the RJ-11 connector. In the following, Konnra connector engineers will focus on introducing you to the RJ-11 connector knowledge. I hope that after our explanation, you will have a deeper understanding of RJ-11 products.
RJ-11 connector
The Konnra connector engineer pointed out that the RJ-11 interface is a dedicated standard connector on a 4-wire telephone line, where RJ stands for "Registered Jack. It is a physical connector most commonly used for telephone line terminals. It is found in telephones and computers. At a higher frequency of use, it has a total of 6 connector sockets, but usually only 2 or 4 sockets are used.
In addition, RJ-11 connector wiring standards can be divided into two types, which are untwisted (flat satin cable) and unshielded twisted pair (UTP). RJ-11 is the most common registered jack, because almost all single-line (POTS) telephone jacks in homes and offices in most countries use this type of connector. Other similar registered jacks include RJ-14 (for 2-wire telephone jack), RJ-25 (for 3-wire jack) and RJ-61 (for 4-wire telephone jack), all of which use 6-position modular connectors.
RJ-11 connector
If the RJ-11 jack is to be used in 2 of the 6 positions, you can use the 6P2C module jack (6 positions, 2 cores) for connection. However, these types of connectors are very rare, because in most cases, the jack of the RJ-11 connector is a 6P4C jack (6 positions, 4 cores), only two of the four wires are not used in the junction box .

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

  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
