N type connector in RF coaxial connector
Product model: N type connector
Product parameters: N series is the first connector with real microwave performance.
Developed N series connectors to meet the needs of RF connectors with long-lasting, weather-resistant mid-size and continuous performance up to 11GHz.
There are two types of N series connectors:
Standard N series (coaxial cable)
Spiral N series (corrugated cable)
The basic application is the termination of medium to mini size coaxial cables: RG-8 and RG-225; RG-58 and RG-141.

N type connector Features/Advantages:
The N-type connector is a small and medium power connector with a threaded connection mechanism. It is suitable for connecting radio frequency cables or microstrip lines in radio frequency loops of microwave equipment and digital communication systems. It can be interchanged with similar international NG products. It has the characteristics of wide frequency bandwidth, excellent performance, high reliability and long life.
N-type connectors are divided into 50 ohm impedance and 75 ohm impedance. The 50-ohm N-type connector has a high-reliability coaxial connector with a frequency of up to 12 GHz and a screw locking system. These two kinds of connectors cannot be connected to each other. The N-type connector adopts a medium-sized screw locking system and has high weather resistance. In addition, the N-type connector also has the advantages of high robustness and high reliability, as well as excellent intermodulation performance.

N-type connectors are used as terminals to connect with coaxial cables, printed circuit boards (PCBs) or terminal blocks. Manufacturers all manufacture them in accordance with the technical requirements of precision radio frequency and microwave industries.
50 ohm N type right angle connector
The structure of the N-type connector is divided into male or female, and the style has standard polarity or reverse polarity. The shape of the N-type connector is divided into straight or right-angle type, 4-hole flange type, press-in type, partition type, 2-hole panel type, 4-hole panel type or free-installation type. The termination methods of these N-type connectors are clamp/weld, clamp/weld (static contact), crimp/weld, field replaceable, welding or welding/welding. The N-type connectors we provide are divided into standard performance or high performance grades, and the body material is brass or stainless steel.

N Type connector is a connector for coaxial cables. It has a threaded connection structure and can be rotated and locked. It is one of the first connectors that can be used to transmit microwave frequency signals, and was invented by Paul Neill of Bell Laboratories in the 1940s and named after Neill’s initials. The signal frequency range supported by the N-type connector is 0 to 11GHz, and the enhanced type can reach 18GHz. There are two types of characteristic impedance, 50 ohms and 75 ohms.
N-type connector
N-type connectors have the characteristics of high reliability, strong vibration resistance, excellent mechanical and electrical performance, etc., and are widely used in radio equipment and instruments under vibration and harsh environmental conditions, as well as ground transmission systems to connect radio frequency coaxial cables.
Among them, 50-ohm N-type connectors are widely used in mobile communications, wireless data, paging systems, etc. 75-ohm N-type connectors are mainly used in cable TV systems, and 75-ohm N-type connectors have a smaller inner conductor diameter. The connector is not compatible.
According to the MIL-C-39012 standard, the angle of the bevel of the pin end is allowed to be between 55 degrees and 65 degrees. The round head process is based on the round head can be inserted at different angles to expand the contact area. It is not easy to contact The contact surface is small and the spark effect is improved; this can’t tell which is better. The judgment of Z is to remove a pin and cut it from the middle. See the material Z inside to explain the problem;
A BNC connector is composed of 11 parts in total, each part has its irreplaceability, and Z mainly affects the contact resistance and corrosion resistance of the BNC connector used; generally, the inner conductor is required to be 1.5mΩ outside The resistance is 1mΩ; the corrosion performance depends on the quality of the coating and the material used; if the material is poor, it is easy to jump off.
BNC Connector cable
The main reason for the loosening of the pins of the BNC connector is that the insulating material used may not be PTFE and the pins are straight; the melting point of the general solder is between 183℃ and 231℃, and the PTFE material It has good heat resistance and can be used for a long time at a high temperature of 260℃ and a short-term use at a low temperature of -268℃. When heated to 415°C, it decomposes slowly, and generally soldering will not cause the pins to loosen.
There is also a good BNC connector that is designed with a resistance ring in the middle of the pin to prevent the pin from sliding back and forth. This needs to be disassembled before you can see it. A simple method is to use a soldering iron to solder the pin for a long time. , If the glue loosens easily, it means that the temperature resistance is not enough.
The shielding ring of the BNC connector with glue and quartet products are mainly seen in low-priced products. The glue is to ensure the toughness of the interface and reduce the amount of metal used. The quartet is because of the alloy material used. The material is relatively brittle. Generally, alloys and copper connectors with better materials use a six-way structure without rubber pads, so six-way connectors are better when buying a BNC connector.
BNC connector is a very common RF terminal coaxial cable terminator. The BNC connector consists of a ZX pin, a jacket and a card seat. BNC connectors are used for the transmission of radio frequency signals, including the transmission of analog or digital video signals, the connection of amateur radio equipment antennas, the connection of avionics and other electronic test equipment.
The poor quality of BNC connectors is generally caused by poor contact and easy oxidation, which may lead to no video, video skipping, image streaks or unclear images, dark and color cast, etc., and the welding is not firm (virtual welding) The above phenomenon will also occur under the circumstances.
bnc connector cable
The soldering failure of the BNC connector may be due to poor soldering iron and soldering tin, or the pins and clamps of the BNC connector are made of copper and iron. So if the above situation occurs, please pay attention to whether the solder wire purchased is low-temperature solder and the power of the electric soldering iron is enough for the temperature, and also pay attention to whether the material of the BNC connector is copper or iron. The iron material must be black if the surface is black. It must be difficult to solder.
BNC connectors are generally used in a weak current environment to pass the resistance test and withstand voltage test. If this phenomenon occurs, it may be caused by static electricity, and the relevant equipment must be grounded. Most of this problem is not the problem of the BNC connector itself, but the grounding problem of the strong electric circuit in the environment where the equipment is used. There is an insulating layer on the wire, so no electricity is felt, but the BNC connector is metal, so it feels electrified.
