How To Judge The Quality Of Tablet Computer Card Holder Push-type Terminal Block Connector? Which Parameters Are The Key?

The quality of the tablet card holder push wire terminal block mainly depends on the following key parameters:

1. Contact resistance: The contact resistance of high-quality push in terminal block wire connector is usually below 20 milliohms. The smaller the value, the better the conductivity. The contact resistance of low-quality push in wire terminal block may be as high as 100 milliohms or more, which will cause signal attenuation and heating problems.

2. Plug-in life: The plug-in times of mainstream brand push fit terminal block connector can reach more than 10,000 times, while low-end products may only have 2,000-5,000 times. Insufficient plug-in times will lead to poor contact.

3. Material selection: High-quality push connector block uses phosphor bronze or beryllium copper as the contact material, and the shell uses high-temperature resistant engineering plastics. Inferior products may use ordinary brass and ABS plastics.
