A connector is an electromechanical component that connects a conductor (wire) to an appropriate mating component to achieve circuit connection and disconnection. Also known as connectors, plugs and sockets in China. For different application objects, frequency, power, application environment, etc., there are various types of connectors. For example, in aviation, there are aviation plugs, aviation sockets, etc., but in life there are waterproof connectors, cable connectors, etc. In today’s society, connectors are widely used in military systems such as aviation, aerospace, and defense.
1, the choice of connector series depends on the application environment of the desired product:
1. Wireless base station
2. Transmission equipment, switching equipment
3. Backplane, set-top box, network card
Choose the connector series according to product performance and mechanical requirements, such as impedance matching, VSWR, maximum frequency, transmission power matching, etc. A typical application environment can guide you to connect the various parts of this product catalog together.
1. Wireless base station
Wireless base stations need to send high-power radio frequency signals, high-speed digital signals and similar signals.
The input / output ports of equipment cabinets are usually used with N-type and 7 / 16-type connectors. Embedded RF modules require blind matching series, such as BMA series, DIN series embedded modules (MARCONI) and panel connectors. The input / output module uses MCX, surface mount series, panel and connector with cable. Finally, use semi-rigid cable assemblies and flexible cable assemblies to complete signal connections for all parts of the device.
2. Transmission equipment, switching equipment
In today’s large-capacity transmission equipment market, such as voice transmission, data transmission, and image transmission, Jipin provides a large number of high-performance RF connection products. From the local end to the user, from the basic equipment to the set-top box, from 50Ω to 75Ω, including connectors, cable assemblies and various consumables, you must use small RF coaxial connectors; such as BNC series, TNC series, ultra-small such as MCX, SMA, SMB, SMC and its miniaturized versions SSMA, SSMB, SSMC. Miniature products, such as MMCX, can provide extremely high mounting density. In the DIN and IEC standard interfaces, high-speed annunciator transmission requires high-performance GHz band BNC connectors.
Wiring equipment is used between backup equipment and exchange equipment in gearbox design. This requires the use of DDF series connectors.
Digital Distribution Frame DDF (Digital DistribuTIon Frames): With the development of communication technology, large-capacity SDH, ATM and other equipment are widely used, which requires the development of the corresponding basic components of the RF coaxial connector, which requires a smaller size, Wider frequency band, better performance and more reliable connection. Through independently developed RF / microwave connector transition compensation CAD system, Jipin has re-optimized the commonly used L9 (Siemens) series, C3 (AT & T) series, C5 (NEC) series, C6 (Fujitsu) series, ERI (Ericsson)) Series and other series connectors. Make it more reliable and better adapt to future high-speed communication requirements.
Jipin uses the three main series of connectors C4, SMZ and CC4 wiring systems developed with reference to international standards. It has an innovative modular design, small size, high applicable frequency and excellent electrical performance.
3. Backplane, network card and set-top box.
In recent years, the coaxial connector market has developed rapidly. In coaxial exit Ethernet applications that provide high-speed channels, BNC connectors occupy a large number of applications.
In the lower layer of the communication link, BNC series connectors are widely used. Due to its unique bayonet locking method, the BNC series is easy to insert and remove, making it widely used.
Recently, because SMB series connectors can increase the density of connector installation, and because of their excellent performance, they can be used for general commercial applications or military applications, so some users gradually choose to use the SMB type series.
In fact, the same application has multiple options to choose from, and users can choose their own suitable connectors according to their needs.
Choice of connection mechanism:
The connection mechanism allows the two connectors to dock with each other, depending on the quality and impedance characteristics required by the two interfaces to match the connection, and the degree of frequent operation. The connection mechanism has a great influence on the performance of the connector. The following are five common connection mechanisms.
Thread connection (thread connection mechanism) This connection method uses connection nuts for connection. Pay attention to limit the maximum torque to prevent the nut from sliding. The use of snails is relatively solid and reliable, so the connectors with embossed connection mechanisms include SMC, SMA, TNC, N, 7/16, SSMA, CC4, L9 and other series. It is mainly used for test equipment, military and telecommunications equipment.
Push-in connection mechanism: (Snap-in coupling mechanism) Push-in connection mechanism is mainly used for small interface connectors, and its installation density is relatively high, because this connection mechanism is more convenient and easy to install, it is usually used in printing Connect on the circuit board (PCB).
The push-in connector has a reed for locking. Its advantage is that it is very fast and convenient to insert and pull out. This connection mechanism is mainly used for small connector series, such as: MMCX, MCX, SMB, SSMB SMZ series.
Slide-on Coupling Mechanism (Slide-on Coupling Mechanism) slide-in connection mechanism is usually used in high-density installation, very easy to insert and pull out, this type of connector is mainly used for coaxial connection system board. This connection mechanism is mainly used for small DIN multi-terminal connectors, such as BMA, C4, C5, C6, ERI. They are usually modular installations
Bayonet couplings (Bayonet couplings) Bayonet couplings have a pair of locking grooves. This locking mechanism is unique to BNC (Bayonet Navy Connector).
The bayonet connection mechanism is usually used in applications that require reliable connections and can be quickly inserted and removed, such as test and measurement equipment and military equipment.
Push-pull self-locking (push-pull Self-Latching) is a unique self-locking method.
It is as fast and convenient to insert as a slide-in connection, but it is also very reliable. When self-locking, even pulling the cable will not unlock it. The small connectors are as follows: 1.0 / 2, 3, 1.6 / 5.6 series. It can be inserted quickly and locked reliably.
