In high-frequency signal transmission, the 90° L-type connector has a series of unique performances.
Electrical performance
Low insertion loss: Insertion loss refers to the power loss generated when the signal passes through the connector. The 90° L-type connector uses special conductor materials and precise manufacturing processes to effectively reduce the attenuation of the signal during transmission. Its internal conductor structure has been optimized to reduce signal reflection and scattering, allowing the signal to pass through the connector more efficiently, and still maintain low insertion loss in high-frequency environments to ensure signal strength and quality.
For example, in microwave communication systems, the low insertion loss 90° L-type connector can ensure that the signal is less lost during transmission, thereby improving the stability and reliability of communication.
High return loss: Return loss reflects the connector's ability to suppress signal reflection. The 90° L-type connector uses precise impedance matching design to make the impedance of the connector as consistent as possible with the impedance of the connected cable or circuit. When the signal is transmitted to the connector, most of the signal can pass smoothly due to good impedance matching, while very few signals are reflected back, thus achieving a higher return loss.
Generally speaking, in high-frequency signal transmission, higher return loss means less signal reflection, which helps to reduce signal interference and distortion and improve the accuracy of signal transmission.
Low radiated interference: During high-frequency signal transmission, the connector may generate radiated interference, affecting the normal operation of other surrounding devices. The 90° l-type connector usually adopts a good shielding design, which can effectively suppress electromagnetic radiation. Its shell is generally made of metal material and has good grounding performance, which can shield electromagnetic interference inside the connector and reduce radiation interference to the outside world.
This is very important for some application scenarios with high requirements for electromagnetic environment, such as aerospace, military communications and other fields.
Mechanical properties
Space saving: The unique shape of the 90° l-type connector enables it to effectively save space during installation. Compared with traditional straight connectors, the L-shaped design allows the connector to be bent in the vertical direction, avoiding space waste caused by the connector being too long in a limited space.
For example, in some high-density circuit board designs, the use of 90° L-type connectors can make the layout of the circuit board more compact and improve space utilization.
Flexible installation: This connector can be installed in different directions and has high flexibility. In some complex equipment or systems, due to space limitations and wiring requirements, the connector needs to be able to adapt to different installation angles. The 90° L-type connector can easily meet this demand and achieve more reasonable wiring and connection by changing the installation direction.
For example, in some narrow chassis, the 90° L-type connector can be flexibly installed according to the structure of the chassis and the direction of the cable, which is convenient for the assembly and maintenance of the equipment.
Stable connection: The 90° L-type connector usually has a good mechanical structure design and can provide a stable connection. Its shell and internal contacts are carefully designed and manufactured with high strength and wear resistance. During use, the connector can withstand a certain amount of external force pulling and vibration to ensure the reliability of the connection.
For example, in some industrial automation equipment, since the equipment will vibrate during operation, the stable connection performance of the 90° L-type connector can ensure the stability of signal transmission and avoid signal interruption caused by loose connection.
Thermal performance
Good heat dissipation: During high-frequency signal transmission, the connector will generate a certain amount of heat. The structural design of the 90° l-type connector is conducive to heat dissipation, and its shell usually has a large heat dissipation area, which can dissipate heat in time. In addition, some connectors also use heat dissipation materials or heat dissipation fins to further improve the heat dissipation efficiency.
Good heat dissipation performance can ensure that the temperature of the connector will not be too high when working for a long time, thereby extending the service life of the connector and improving its reliability.
