On the 1.5 kW four-pole special motor for the X6325 rocker universal milling machine, the heat shrinkable identification tube produced by Kehong Electronics Co., Ltd. is used as the line end mark of the motor lead wire instead of the commonly used aluminum label.

There are twelve outlets for this accessory motor. It does not need a wiring board (this structure refers to the US imported prototype). Although it is a small part in the whole motor, it seems trivial, but it is directly related to whether the user can correct it. Big problem with use. Because the aluminum label is obviously unreliable on this structure, the possibility of falling off is very large. If a general plastic sleeve is used, the thickness is difficult to control, and the thickness is too small to be loose, so it is too loose to fall off. Can not be used.

After collecting from many parties, we found that in the electronics industry, heat shrinkable identification tubes are widely used as packages for electrolytic capacitors, electronic devices, batteries, etc., especially for housings of electrolytic capacitors. This sleeve can also be printed.

The heat shrinkable identification tube is simple in process and does not require a mold. Different thickness guide wires can be used with different diameter sleeves, which is convenient to use.

The sleeve will not fall off after being placed on the sleeve. There is no possibility that the aluminum label sheet will loosen and cause a shell or short circuit.

Heat shrink tubing is low cost.

The heat shrinkable sleeve is aesthetically pleasing and does not consume non-ferrous metals.

In addition, it can also be used as the protection of the motor shaft extension. When the motor is shipped from the factory, it is placed on the shaft extension. After being heated and contracted, it is tightly wrapped around the shaft extension and the flat key. It is more advanced than the plastic paper wrapping, especially for the surface paint. It is more convenient to use on lacquered motors.

热缩标识管在电机上的应用

X6325摇臂万能铣床配套的1.5千瓦四极专用电机上,采用了柯鸿电子有限公司生产的热缩标识管,作为电机引出线的线端标志,代替了通常所用的铝质标号片。

该配套出口专用电机出线头有十二根,它不用接线板(此结构乃参照美国进口样机)虽然在整个电机中它是一个很小的零件,似乎微不足道,但却直接关系到用户能否正确使用的大问题。因为采用铝质标号片在这种结构上显然不可靠,脱落的可能性很大,如果采用一般的塑料套管,粗细很难控制,选细了套不上,粗了太松要脱落,因此都不能采用。

经过多方而搜集,我们发现在电子行业中, 热缩标识管广泛地用作电解电容、电子器件、电池等的封装,特别是用在电解电容的外壳上。这种套管也可以印字。

热缩标识管工艺简单,不需要模具。不同粗细的引接线可用不同直径的套管,使用方便。

套管套上后不会脱落。没有铝标号片松动造成碰壳、短路的可能。

热缩套管成本低。

热缩套管美观醒目不耗用有色金属。

另外,它也可用作电机轴伸的保护,电动机出厂时套在轴伸上,经加热收缩后紧紧包在轴伸和平键上,比用塑料纸包扎美观先进,特别是表面油漆用烘漆的电机上使用更为方便。
