KH-XH-2A-Z Connector Product Picture

Board-to-board connectors are currently the strongest type of connector in terms of transmission capability among all connector products. They are mainly used in industries such as power systems, communication networks, financial manufacturing, elevators, industrial automation, medical equipment, office equipment, home appliances, and manufacturing. Board-to-board connectors connect two PCB boards to achieve inter-board signal connection, making them the strongest type of connector in terms of transmission capability. Kinghelm KH-XH-2A-Z, as a board-to-board/wire-to-wire connector, has the following advantages:

1.Lower contact resistance.

2.Good resistance to mechanical shock and salt spray.

3.Strong anti-aging and UV resistance, suitable for use in harsh environments.

4.Simplifies the assembly process of electronic products and batch production process.

5.Easy to maintain. If a component of the connector fails, the failed component can be quickly replaced when the connector is installed.

6.Easy to upgrade. With technological progress, the old components can be replaced with new and more advanced ones when the board-to-board connector is installed.

The application of board-to-board connectors presents some challenges, such as the height, pitch, and pin structure of the connector need to meet different requirements, and they also need to have good resistance to mechanical shock and salt spray. The parameter advantages of Kinghelm KH-XH-2A-Z can solve these challenges and meet the needs of different industries.

Product Specification of KH-XH-2A-Z

The Kinghelm KH-XH-2A-Z is mainly used for PCB BTB connectors, meeting the requirements of high frequency, thinness, and miniaturization. It is currently the strongest product in terms of transmission capability among connector products, and there is still a lot of room for penetration in the high-end market. In mobile phones, BTB board-to-board connectors are mainly used to connect PCBs and modules, motherboards, etc., and can also connect PCBs and FPCs to achieve mechanical and electrical connections. The shape and height of the connector depend on the PCB layout, and the height of the connector after insertion into the BTB is determined by the maximum height of other components on the PCB. With the rich SMT process, PCBs can now be double-sided soldered with electronic components, and the density of surface components has increased. With the trend of slimming down mobile phones and the increasing complexity of internal structures, corresponding connectors are developing towards miniaturization and narrowness, and BTB connectors are also developing towards smaller pitch, more numbers, higher frequency. Compared with other connectors, BTB connectors have the advantages of noise reduction, stable high-frequency transmission, thinness, and no need for soldering. In terms of usage, the number of BTB connectors used in iPhones has increased from 7 pairs in iPhone 7 to 14-16 pairs in iPhone XS, while the number of BTB connectors used in other ordinary mobile phones is around 7-10 pairs. The demand for BTB connectors in smartphones is on the rise, and there is still some room for penetration in the high-end market.

In summary, the Kinghelm KH-XH-2A-Z, as a board-to-board/line-to-line connector, has superior performance and a wide range of application fields, which can meet the needs of different industries. With the continuous development of technology, the application prospects of board-to-board connectors will be even broader.
