插針插孔對(duì)銅原料到底有哪些嚴(yán)格要求？
插針插孔對(duì)于加工原料銅的質(zhì)量要求非常高，要求銅材料沒(méi)有任何其它雜質(zhì)，表面必需干凈、平整、光滑。插針插孔的直徑穩(wěn)定，而且公差范圍比較小，直徑的變化都會(huì)改變阻抗均勻性和回波的性能，因此要求精確度非常之高。
插針插孔有兩個(gè)作用，靠前個(gè)作用是回路導(dǎo)體作用。第二是起到屏蔽作用。泄漏電纜的外套提決定漏泄的性能。同軸饋線電纜和超柔電纜的外導(dǎo)體是由軋紋銅管焊接而成的，這些電纜的插孔完全封閉，不允許電纜有任何輻射。
插針插孔通常由銅帶縱向包裹而成。在插孔上，開(kāi)有縱向或橫向的槽口或者小孔。外導(dǎo)體開(kāi)槽在軋紋型電纜中比較常見(jiàn)。通過(guò)沿軸向方向?qū)埣y波峰進(jìn)行等距離切削開(kāi)槽形成。削去的部分比較小，而且槽孔間距要比電磁波長(zhǎng)要小。
將非漏泄型電纜按以下方法加工可制成漏泄電纜：對(duì)非漏泄型電纜中常以見(jiàn)的普通皺紋型電纜的插孔波峰進(jìn)行切削，得到一組合適的槽孔結(jié)構(gòu)。插針插孔對(duì)銅材的要求非常高，導(dǎo)電率高，無(wú)雜質(zhì)。尺寸要嚴(yán)控制在要求的范圍之內(nèi)。以上是關(guān)于插針插孔對(duì)原料銅具體要求，希望在加工插針插孔選擇材料方面能夠幫助到大家！
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!
