We all know that there is a connecting wire harness in a field with a display screen, and the wire harness must be inseparable from the terminal connector, because it plays an indispensable power and signal transmission function. As a connecting conductor at the end of the connection line, the quality is particularly The essential!
In daily life, LCD screens often appear: flickering screens, blurry screens and many other problems, which may be caused by the following factors:
1. Important: The wire manufacturer did not choose the terminal connector product when processing the wire harness, which caused the problem of poor oxidation contact in the later use.
2. Whether there is a shielding coil in the wiring harness connected to the LCD screen. If there is no black shielding coil for anti-interference, it will also cause great interference to the screen.
3. Also check whether there is interference nearby, such as high-power audio, power transformer. LCD screens are easily disturbed by strong electric or magnetic fields. Sometimes screen jitter is caused by the magnetic field or electric field near the LCD screen.
For the first point, what should the wiring harness manufacturer pay attention to when choosing terminal connectors?
1: Pay attention to whether the quality of the connector supplier's hardware raw materials (phosphor bronze and brass) copper strip is qualified and whether there is a relevant test report.
2: Whether the electroplating supplier of the connector manufacturer is stable and reliable.
3: Whether the thickness of the electroplating coating is qualified, it needs to go through strict salt spray and other related tests.
4: The storage of terminal products in the warehouse is also very important. Pay attention to the natural oxidation problems such as humidity in the air.
The benefits of terminal electroplating: protect the terminal reed base material from corrosion, slow down the oxidation of the product and ensure the service life of the product. Establish and maintain a good fusion between the terminal and the PIN pin contact surface to maximize, in other words: make it easier to achieve metal-to-metal contact.
