Patch connector

There are many types of connectors, which can be divided into circular connectors, rectangular connectors, square connectors, and custom connectors. According to the contact body termination form: crimping, welding, winding; screw (nut) fixed; according to the connection can be divided into: Board to board connector, Wire to board connector, Wire to wire connector and Board-in Connector. Let's talk about the patch connector in the wire to baord connector today.
KR2501 DIP connectors
Surface solder mounting technology has been used by some manufacturers since the 1950s. However, the use of patch connectors has only recently begun, and has gradually been valued by manufacturers. This situation is due to the technical difficulties faced by the SMT connector and the failure to perceive the patch panel to save the board area. As the patch process can be found to improve the production efficiency and reduce the cost of the manufacturer, the board area can be reduced, and the design flexibility can be improved, so that the patch connector can be widely used.
PCB with connectors
Patch connectors are divided into: horizontal connector (SMT) and vertical connector (DIP). SMT is generally mounted with leadless or short lead surface mount components. It is necessary to print solder paste on the board first, then mount it on the mounter, and then fix the device by reflow soldering. DIP solders are devices that are packaged in a straight-in form and are fixed by wave soldering or manual soldering.
KR2501 SMT connectors 
The patch connector has a furnace temperature of 250° or more and 3-5 s. The composition of the patch connector: plastic parts and pin needles, the plastic parts are generally PA6T and PA9T, are high temperature resistant materials. Patch connectors are generally used in highway cameras, stereo DC fans, smart electronics, air conditioners, HD LCD TVs, notebook computers and other fields. Among them, the material of Pin is generally brass, bronze, phosphor bronze, and the like. The plating is generally gold plated (half gold) or tin plated. The coating effect of the pin needle is anti-oxidation, improve the conductivity and increase the transmission speed of the signal.

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
