As applications require higher and higher frequencies,shielding and electromagnetic interference(EMI)have become key problems.EMI is a bad phenomenon that occurs when external sources interfere with signals.The signal leakage problem of connectors is called electromagnetic compatibility or EMC,which usually leads to EMC test failure.In short,the lack of proper electrical connection and shielding of the connector will externally affect the signal of the conductor.Another consideration in the design of subminiature pu…
Although brass is a material with good conductivity,it is easy to deform and fatigue quickly after repeated bending.It is usually used as a fixed contact in cheap connectors or as other metal parts in connectors.Connectors with brass contacts should not be used where good elasticity is required,but brass can still be used as contacts in many places due to its low cost.Phosphorus bronze is harder than brass and can maintain long-term elasticity at the same time.It is usually used as connector contact material with op…
1.The connector can be selected according to the straight type,curved type,cable outer diameter,shell fixing requirements,volume,weight and whether to connect metal hose.2.The connector can be selected according to the appearance,shape and color of the connector.3.The appropriate connector can be selected according to the actual use of the connector.Generally,the environmental factors affecting the performance of the connector include temperature,humidity,sudden temperature change,atmospheric pressure,corrosive envi…
1.When selecting the connector,pay attention to its purpose requirements.For example,the connectors used by audio and TV must be different.2.When selecting the connector,pay attention to whether its overall dimension,installation dimension and opening dimension meet the specifications.3.When selecting connectors,pay attention to the number of plugs,and the number of plugs required shall be consistent.4.When selecting the connector,the product model and specification shall be unified.
1. First, distinguish the concepts of "connector", "terminal" and "connector"①Connector, namely CONNECTOR. Also called plug-in connector. It is a component that electronic engineering and technical personnel often contact. Also called connectors, plugs and sockets. Generally refers to electrical connectors. That is, a device that connects two active devices to transmit current or signal.②The connector is a positioning connector for connecting electronic circuits. It is composed of two…
