Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hybrid stepping motor accessories, in particular to a connecting component of a combined stepping motor. Background Art
[0002] Combined stepper motors are also called hybrid stepper motors. Hybrid stepper motors combine the advantages of permanent magnet and reactive motors and are divided into two-phase, three-phase and five-phase. The two-phase step angle is generally 1.8 degrees, and the five-phase step angle is generally 0.72 degrees. As the number of phases (the number of energized windings) of the hybrid stepper motor increases, the step angle decreases and the accuracy improves. Combined stepper motors are generally provided with multiple strands of wire, and the ends of the wires are generally connected to the rotor on the combined stepper motor.
[0003] The multi-strand wires on conventional modular stepper motors are usually directly spot-welded to the corresponding conductive contacts. The spot-welded parts are easily pulled by external forces, causing the wires to fall off from the conductive contacts. The modular stepper motor lacks a connection component to clamp and limit the cable, and it is impossible to clamp and limit the end of the cable connected to the conductive contact. When external forces pull or unintentional foreign objects pull the cable, it is very easy to cause the end of the cable to fall off from the wire contact, affecting normal power supply and causing inconvenience to the user. In view of this, we propose a connection component for a modular stepper motor. Utility Model Content

[0025] Specifically, a built-in cable 231 electrically connected to the conductive contact 11 is provided in the insulating sleeve 23, and the insulating sleeve 23 protects the built-in cable 231 inside for insulation protection operation; the stud 245 presses the soft anti-slip pad 242 downward to press the insulating sleeve 23 tightly against the rubber pad 22, thereby limiting the insulating sleeve 23, so that after the external force pulls the insulating sleeve 23, it is not easy to pull the end of the built-in cable 231 off the conductive contact 11.
[0026] In this embodiment, a first arc-shaped hole 21 is provided on the fixed bottom cover 20 , and the rubber pad 22 is integrally formed on the hole wall of the first arc-shaped hole 21 , so as to facilitate the installation operation of the rubber pad 22 .
