Description
1、技术领域： 1. Technical field:
本实用新型涉及一种引线护套，特别是一种电机用引线护套。The utility model relates to a lead wire sheath, in particular to a lead wire sheath for a motor.
2、背景技术： 2. Background technology:
普通的电机包括定子和转子两部分，定子或转子上有绕组，绕组与外部电源连接，在外部电源电流通过时定子产生磁场。转子有电流通过时，与定子磁场相互作用，产生电磁转矩而使转子转动。A common motor consists of a stator and a rotor. There are windings on the stator or the rotor. The windings are connected to an external power supply. When the external power supply current passes, the stator generates a magnetic field. When the rotor has current passing through it, it interacts with the magnetic field of the stator to generate electromagnetic torque to make the rotor rotate.
为连接绕组和外部电源，引线通过设在电机外壳上的孔进入电机内部。引线一端连接绕组，一端连接外部电源。引线用塑料或橡胶绝缘。但是，设在电机外壳上的孔会导致电机部件暴露在不良的环境里，例如水、油、灰尘。另外，电机外部的引线如果不能得到保护，会破坏引线的绝缘性能，从而影响电机的正常工作。一种保护引线的方式是增加引线绝缘套的厚度。但这样会增加成本，并且不能防止水、油和污物进入电机外壳。其他保护方式包括使用硬塑料套管，半柔性金属套管等，电机引线安装在这些套管里。使用套管能够提供一些保护，但是不能完全防止水、油等从孔进入电机内部。同样，制造这些套管的成本很高，而且有些情形，这些套管的不能够满足使用。比如，因为硬塑套管的长度是固定的，当电机被安装在距离控制元件较远的地方，就需要一个较长的套管。In order to connect the winding and the external power supply, the lead wires enter the interior of the motor through the holes provided in the motor casing. One end of the lead wire is connected to the winding, and the other end is connected to an external power source. The leads are insulated with plastic or rubber. However, the holes provided in the motor casing will expose the motor components to undesirable environments such as water, oil, and dust. In addition, if the lead wires outside the motor cannot be protected, the insulation performance of the lead wires will be destroyed, thereby affecting the normal operation of the motor. One way to protect the leads is to increase the thickness of the lead insulation. But this adds cost and does not prevent water, oil and dirt from entering the motor housing. Other methods of protection include the use of hard plastic sleeves, semi-flexible metal sleeves, etc., into which the motor leads are mounted. The use of bushings can provide some protection, but cannot completely prevent water, oil, etc. from entering the motor through the holes. Also, the cost of manufacturing these bushings is high and in some cases the bushings are not adequate for use. For example, because the length of the hard plastic bushing is fixed, a longer bushing is required when the motor is installed farther away from the control element.
美国专利(专利号5519273)提供了这样一个连接装置，其包括一个底座及一个与底座一体成型的凸台，底座通过凹槽安装在电机外壳的引线孔上，凸台与引线套管连接，凸台表面上有凸起的螺纹线，可以与引线套管配合紧密，整个连接装置采用塑料成型。U.S. Patent (Patent No. 5519273) provides such a connection device, which includes a base and a boss integrally formed with the base, the base is installed on the lead wire hole of the motor casing through a groove, the boss is connected with the lead sleeve, and the boss There are raised threads on the surface of the table, which can be closely matched with the lead sleeve, and the entire connecting device is molded by plastic.
但是上述连接装置存在以下问题：1，安装过程不易定位，连接不牢靠，电机外壳是金属件，而护套是塑料件，安装在一起影响电机整体外观，2，引线护套采用塑料件，在室外长时间使用容易老化产生变形或裂纹，影响其保护效果；3，护套表面的螺纹采用断裂式双螺纹结构，结构和加工工艺比较复杂。However, the above-mentioned connecting device has the following problems: 1. It is difficult to locate during the installation process, and the connection is not reliable. The motor shell is a metal part, and the sheath is a plastic part, which affects the overall appearance of the motor when installed together. 2. The lead sheath is made of plastic parts. Long-term outdoor use is prone to aging and deformation or cracks, which will affect its protective effect; 3. The thread on the surface of the sheath adopts a broken double-thread structure, and the structure and processing technology are relatively complicated.
