Connector is a relatively common electronic component used in modern manufacturing, and it’s important to improve the process of manufacturing . Anyway, the application of connectors in electronic products in our life is indispensable. The electronic products without the connector are useless decorations. Although it is the main body and the connector is only an accessory, the importance of the two is the same , especially in the realizing the information transmission of electromechanical equipment, it shows the important role of the connector.
1. AS the importance of connectors highlights the importance of its own quality
Its important role also needs to benefit from the reliable quality of its products. Choosing high-quality connector products is the key to determining the quality of our production . On the contrary, it will bring us a lot of trouble.
2. How to select and apply connectors?
We must make necessary selection and screening when choosing connectors ,so that we can really find the products we real need and play the service role of connectors in our lives.
Take a look at the quality and standard of its special connector production, which is also a criterion for product evaluation.
① Structural dimension: The external dimension of the connector is very important. There are certain space restrictions for the connection in the product, especially the single-board connector, which can’t interfere with other components. Select the appropriate installation method according to the use space and installation position (installation includes front installation and rear installation, and installation and fixing methods include screws, collars, rivets or quick locking of the connector itself, etc.) and shape (straight, curved, T type, round, square);
② Impedance matching: Some signals have impedance requirements, especially RF signals, which have stricter impedance matching requirements. When the impedance does not match, it will cause signal reflection, which will affect signal transmission. There is no special requirement for the impedance of the connector for general signal transmission
③ Shielding: With the development of communication products, EMC has been paid more and more attention. The selected connector needs to have a metal shell, and the cable needs to have a shielding layer. The shielding layer should be connected with the metal shell of the connector to achieve shielding. For the effect, the injection molding method can also be used to wrap the plug part with copper skin, and the shielding layer of the cable and the copper skin are welded together.
④ Mis-insertion prevention: There are two aspects to prevent mis-insertion: on the one hand, the connector itself, which rotates 180 degrees, and the wrong connection leads to wrong signal connection. Adjust the relative positional relationship of the connectors to make the assembly unique; on the other hand, in order to reduce the types of materials, several signals use the same connector. At this time, it is possible to insert the A plug into the B plug. At this time, attention should be paid to , if such a situation will cause serious consequences (not simple alarms, destructive), the A and B interfaces must be selected as different types of sockets.
⑤ Reliability of connectors: connectors are used to connect signals, so the connection parts should be reliable (for example, surface contact is better than point contact, pinhole type is better than leaf spring type, etc.)
⑥ Use environment: When the connector is used in outdoor, indoor, high temperature, high humidity, salt spray, mold, cold and other environments, there are special requirements for the connector.
⑦ Versatility: In the selection process of connectors, we should choose common objects as much as possible, especially among products of the same series, the selection of connectors has strong versatility, reducing the types of materials, increasing the quantity and reducing costs, and reducing supply. cargo risk.
⑧ Locking function: In order to prevent the connector from falling off when mating and to ensure good contact, the connector needs to have a locking function.
⑨ Cost: Cost is also an important factor in the selection process. With the increasingly fierce market competition, the appropriate selection of connectors, the cost of the connector itself and the processing cost need to be comprehensively considered.
⑩ Availability: The supply of connectors will be affected by many factors. General-purpose connectors are better than non-universal ones, and domestically produced ones are better than foreign ones.
⑪ Plugging frequency
⑫ The external material design of the connector can better reflect its environmental performance, because the external environment is extremely complex, so adapting to these complex environments can ensure the performance of its using
