The radiation cross-linked heat-shrinkable sleeve (hereinafter referred to as heat-shrinkable tube) has the unique function of automatically reducing the diameter after being heated, and also has the characteristics of high temperature resistance, aging resistance, acid and alkali resistance, excellent insulation performance and high mechanical strength, so in modern A new type of insulating encapsulation material has become an essential part in electronic equipment. Electrical connectors, probes and wire ends used in electric hot water bottles, electric coffee makers, automatic dishwashers, etc., are particularly necessary for heat-shrinkable tubes for insulation and encapsulation due to the high temperature and high humidity.

The heat-shrinkable tube is very convenient to use. As long as the heat-shrinkable tube of the appropriate length is placed on the packaged object, the heat-shrinkable tube is heated to 120 ° C or higher by a heat source such as a hair dryer or heated by a hot electric iron shell. The heat shrinkable tube will automatically shrink radially and wrap the wrapped object.

Heat shrink tubing is often used for insulation recovery at wire branch joints.

The solder joints of the branch leads should be smooth and free of burrs, so as not to be pierced by the burrs when the heat shrinkable tubes shrink, which affects the insulation effect. If the joint needs to be immersed in water, a layer of squeegee glue can be applied after the wire insulation and the heat shrinkable tube overlap. Reheat and tighten the heat shrinkable tube.

The heat-shrinkable tube encloses the end of the wire. After the end insulation of the wire is stripped, the mechanical stress at the root of the core is concentrated and easily broken. For example, in a connector with a small space, the distance between the legs is small, and the pins are easily contacted with a short circuit. In these cases, the end of the wire is wrapped with a heat-shrinkable tube to integrate the soldering piece and the wire insulation package, which disperses the mechanical stress and encapsulates the solder joint to prevent corrosion of the solder joint by harmful gases such as water vapor. The reliability of the connector work.

An example of applying a resistor or a small circuit board to a lead and encapsulating it with a heat shrinkable tube. The wire solder joint of the resistor is bent into a ring shape, which is favorable for the solder joint to be firm and smooth.

Heat shrink tubing is used for wire display. Users can print the product name, model, factory name, etc. on the self-adhesive paper according to the drawing number or cover the heat-shrinkable tube. This code method is convenient, clear and not easy to fall off.

The heat shrinkable tube can also be used for the insulation encapsulation of the coil and the probe. In short, after the electronic equipment uses the heat-shrinkable tube, the wiring of the whole machine can be neat and beautiful.

The heat shrinkable tube is marked in the A/B form, ie the tube with an inner diameter of A mm can be shrunk to a minimum of B mm.

热缩管在电子设备中的应用

辐射交联热缩套管(下称热缩管)受热后具有直径自动缩小的独特功能,另外还具有耐高温、耐老化、耐酸碱以及绝缘性能优良、机械强度高等特点,所以,在现代电子设备中已经成为必不可少的新型绝缘包封材料。电热水瓶、电咖啡壶、自动洗碗机等所用的电气接头、探头和电线端部,因处于高温高湿的恶劣环境之中采用热缩管来绝缘包封尤为必要。

热缩管使用起来很方便.只要将适当长度的热缩管套在被包物体需包极部位,用电吹风等热源对热缩管加热至120℃以上或用热的电烙铁外壳接触加热,热缩管就会自动径向收缩,包紧被包物体.

热缩管常用于电线分支接头处的绝缘恢复。

分支引线的焊点要光滑,不能有毛刺,以免热缩管收缩时被毛刺刺穿,影响绝缘效果,如果接头需要防浸水,可在电线绝缘与热缩管重叠部位涂抹一层抓丁胶水后再加热缩紧热缩管。

热缩管包封电线端部.电线的端部绝缘层被剥除后,芯线根部机械应力集中,易折断。再如在空间较小的接插件上,各脚间距离较小,引脚之间很容易接触短路。在这些情况下,用热缩管包封电线端部,使焊片及电线绝缘包为一体,既分散了机械应力,又包封了焊点,防止水汽等有害气体对焊点的腐蚀,提高了接插件工作的可靠性。

一条引线上申接一个电阻或一个小电路板后用热缩管包封的实例。电阻的引线焊点处弯成圈形,有利于焊点的牢固和光滑。

热缩管用于电线示码。用户可自己按图纸编号或根据需要将产品名称、型号、厂名等打印在不干胶纸上,外包热缩管,这种示码方法方便、清晰、不易脱落。

热缩管还可以用于线圈、探头的绝缘包封。总之,电子设备使用热缩管后,可使整机布线整洁美观。

热缩管的规A/B形式标注,即内径为A毫米的管子,最小可收缩至B毫米。
