用硬焊料及电阻焊接导线和4PT、4PTT、2PM及2PMTC插塞接头,是通过碳电极所产生的热来加热钎焊元件。该方法的缺点是劳动量大、加热时间长、焊后必须清理焊剂。采用PC和PPC系列小型插塞时,接点布置比4PT型插头更加密集,且其连接导线为0.12mm~2和0.2mm~2的MC16—13,所以用 Solder the leads and solder the 4PT, 4PTT, 2PM, and 2PMTC plugs with hard solder and resistors, which heat the brazed components through the heat generated by the carbon electrodes. The disadvantage of this method is labor, heating a long time, must be cleaned after welding flux. When using PC and PPC series small plug, the contact arrangement is more dense than the 4PT type plug, and its connecting wire is MC16-13 of 0.12mm ~ 2 and 0.2mm ~ 2, so
