What is a European connector?
European-style connector is a type of connector that adopts European standards and is widely used. It is usually used in 19in standard chassis. During its installation, positioning accuracy, installation firmness, and replaceability are important, and positioning accuracy can be Ensure that the connectors are correctly mated when the circuit board is loaded into the chassis. The installation firmness is used to ensure that the connector does not fall off or shift when the circuit board is unplugged, to ensure the repeatability of unplugging and plugging. The replaceability of the connector is used when the same When the upper part of the connector of the chassis needs to be disassembled or replaced, it can be operated conveniently and quickly.
What is a European connector? How to install a European connector
There are generally two installation methods for European connectors:
1. Make the flat connector of the same chassis into a connector backplane, and then fix it on the chassis. The mode of the component backplane can make the interconnection between the entire row of connectors simple and stable. Wires are routed in the PCB, and the installation of the backplane is also very convenient. When a connector in the backplane needs to be removed, the entire backplane needs to be removed, and the backplane needs to be returned to the PCBA manufacturer to proceed. The maintenance of the connector is very inconvenient, and the cycle will be very long, so the replacement cost of the backplane mode connector will be relatively large.
2. Install the flat connection connector of the same chassis on the connector fixing strip, and then install the connector fixing strip on the chassis, or first install the fixing strip on the chassis, and then install the connector from the inside of the chassis Install one by one on the fixing strip. This mode of connector installation is not convenient, and it is not easy to determine the left and right installation positions of the connector. When a connector fails and needs to be replaced, the circuit board of the chassis needs to be aligned. All are removed, and then the electronic connector is disassembled from the inside of the case. The operation process is relatively cumbersome. With this installation method, there will be a cable connected to the end of the connector. If a shielded cable is used, the shielding of the shielded cable The layer grounding problem will be extremely difficult to solve.
