The quality requirement of the pin jack for the raw material copper is very high, the copper material is required to be free from any other impurities, and the surface must be clean, smooth and smooth. The diameter of the pin jack is stable, and the tolerance range is relatively small. Changes in the diameter will change the impedance uniformity and echo performance, so the accuracy is required to be very high.
The pin jack has two functions. The first function is the loop conductor. The second is to play a shielding role. The jacket lift of the leaking cable determines the performance of the leakage. The outer conductor of the coaxial feeder cable and the superflexible cable is welded from the rolled copper tube, and the jacks of these cables are completely closed, allowing no radiation from the cable.
Pin jacks are usually made of copper strips wrapped lengthwise. A longitudinal or transverse notch or hole in a jack. Grooving of outer conductor is common in rolled cable. The groove is formed by equidistant cutting along the axial direction. The cut part is smaller, and the slot spacing is smaller than the electromagnetic wave length.
The non-leakage cable can be made into leakage cable by machining in the following way: a set of suitable slot structure can be obtained by cutting the jack crest of the common wrinkled cable in the non-leakage cable. The requirements of the pin jack on copper material are very high, high conductivity, no impurities. The size should be strictly controlled within the required range. The above is about the specific requirements of the pin jack on the raw material copper, hope in processing pin jack selection material can help you!
