，如果插座意外短路，是后者铰接到一起的，也有可能烧坏。
一般解决方法就是：涮锡前接一个短头，把短头另一端接到接线柱上。
这种是并联这种接线的最大优点：每个插座坏了，都不会影响其他插座的使用。
因为火线零线和地线都是从母线上引下来的。
接线的时候一般是把母线的绝缘层去掉一点，采用T型接线。
三种接法：导线有单股的也有多股的这种接法最节省，接点怎么处理。
如果在接线位置放一个线盒也可以。
如果是吊顶的**了，线盒都省了。

PIC的输入端子除了可以接通有触点的开关外，还可以接一些无触点开关，如无触点接近开关，当金属体靠近探测头时，内都的晶体管导通，相当于开关闭合。
根据晶体管的不同，无触点接近开关可分为NPN型和PNP型，根据引出线数量不同，可分力3线式和2线式。
3线式无触点接近开关的接线图a是3线NPN型无触点接近开关的接线它采用漏型输入接线，在接线时将S／S端子与24V端子连接，当金属体靠近接近开关时，内部的NPN型晶体管导通，X00输入电路有电流流过，电流途径是：24V端子S／S端子ーplc内部光电耦合器一X0端子编子接近开关ー0V端子，电流由公共端子（S／S端子）输入，此为源型输入。
2、绝缘材料：高密度聚乙烯或聚丙烯，按照全色谱标准标明绝缘线的颜色。
3、绝缘线对：把二根不同颜色的绝缘线按不同的节距扭绞成对，并采用规定的色谱组合以便识别线对。
4、缆芯结构：以25对为基本单位，超过25对的电缆按单位组合，每个单位用规定色谱的单位扎带绕扎，以便识别不同的单位。

HYAT23 armoured communication cable USES: armoured communication cable mechanical protective layer can be appended to the structure of the cable, with the mechanical strength of the cable, antierosion capability, is vulnerable to mechanical and vulnerable to erosion area and design of telephone cable. Any kind of laying can be adopted, which is more suitable for direct buried laying in rock area. Armored communication cable structure: 1. Basic cable: any filled and unfilled cable with single sheath or double sheath structure. 2. Armored communication cable mechanical protection layer: type 53 adopts 0.15mm thick corrugated steel belt, which is longitudinal wrapped on the basic cable and overlapped on both sides. The surface of the steel belt is coated with plastic to prevent corrosion and water intrusion. The type 23,22 has similar performance with double steel band wrapping. 3. Armored communication cable sheath: black high-molecular weight low-density polyurethane or polyurethane sheath. Sheath thickness may depend on the basic cable outer diameter.
