[0002] Induction motors are widely used in daily life. When wiring, multiple connecting wires on them are connected to external power lines.

[0003] After searching, it was found that the existing technology, such as the Chinese patent (authorization number: CN216086353U), discloses an outer rotor direct-drive DC brushless motor for automatic induction doors. A retaining ring is welded on the top of the motor body, a fixed plate is provided inside the retaining ring, the outer wall of the retaining ring is screwed with an internal threaded tube, a swivel is welded on the top of the internal threaded tube, and the inner wall of the swivel is connected to a movable plate through a ring groove and a circular ring. The first terminal and the second terminal can be clamped and fixed by the movable plate and the fixed plate. Compared with the traditional screwing method, the connection is more stable, and the retaining ring can be used to provide external protection for the first terminal and the second terminal to prevent foreign objects from causing damage to the first terminal and the second terminal.

[0004] Although the above-mentioned public technology can connect the connecting wires and the power cord, there is no protective structure designed on the upper end of the retaining ring, which will also cause dust, water and other debris to enter the retaining ring and cannot provide good protection for the wiring point. Therefore, improvement is needed. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] like Figure 1-4 As shown, the utility model provides a wiring device for an induction motor, comprising a plurality of fixing mechanisms arranged in a rectangular array, the lower ends of the fixing mechanisms being fixed to the top of the housing of the induction motor, and each fixing mechanism being provided with a locking mechanism.

[0024] like Figure 5 As shown, in the present invention, the fixing mechanism includes an insulating cylinder 1 whose lower end is fixed to the induction motor, the insulating cylinder 1 is connected to the wire outlet hole on the induction motor housing, and the locking mechanism is installed in the insulating cylinder 1.

[0025] like Figure 3 、 Figure 6 As shown, in order to allow the connecting wire M to pass through, an insulating washer 2 is fixed to the lower end of the insulating cylinder 1, and the inner hole of the insulating washer 2 is connected to the wire outlet hole on the induction motor housing.

[0026] like Figure 2-3 As shown, in order to facilitate the stacking of the first connection end M-1 and the second connection end N-1, a notch 1-1 is opened downward at the upper end of the insulating cylinder 1, and the lower end of the notch 1-1 is located above the insulating gasket 2, so that after the locking insulating column 3 is installed in the insulating cylinder 1, the wiring point can be sealed.

[0027] like Figure 1 、 Figure 3 As shown, in the utility model, the locking mechanism includes a locking insulating column 3 that can be detachably installed in the insulating cylinder 1. The locking insulating column 3 is provided with a connecting structure for the external power line N to pass through. In order to realize the detachability of the locking insulating column 3, the locking insulating column 3 is a bolt, and the inner wall of the insulating cylinder 1 is provided with an internal thread that cooperates with the bolt.

[0028] like Figure 3 As shown, in order to enable the power cord N to pass through the bolt, the connecting structure is a vertical connecting hole 3-1, which extends from the upper end to the lower end of the locking insulating column 3. The second connection end N-1 of the power cord N and the first connection end M-1 of the connecting wire M are stacked and clamped between the top of the insulating gasket 2 and the lower end of the bolt.

[0029] like Figure 5-6As shown, when in use, the locking insulating column 3 is twisted upward to be removed from the insulating cylinder 1. After the connecting wire M is led out from the housing of the induction motor, it is inserted into the insulating gasket 2 from the lower end of the insulating cylinder 1 and extended from the top of the insulating gasket 2. The power line N is inserted into the connecting hole 3-1 and extended from the lower end of the connecting hole 3-1. The staff inserts their fingers into the insulating cylinder 1 through the notch 1-1, bends the first connecting end M-1 of the connecting wire M, and then screws the locking insulating column 3 downward into the insulating cylinder 1, and brings the second connecting end N-1 of the power line N close to the insulating cylinder 1. When the first connection end M-1 and the second connection end N-1 reach the top of the insulating gasket 2, extend your fingers into the insulating cylinder 1 from the notch 1-1, bend the second connection end N-1, and make the second connection end N-1 located directly above the first connection end M-1. Then, pinch the power cord N and continue to rotate the locking insulating column 3 downward so that the two rotate relative to each other until the lower end of the locking insulating column 3 clamps the first connection end M-1 and the second connection end N-1 to achieve wiring. Conversely, when removing the wiring, rotate the locking insulating column 3 upward to detach it from the insulating cylinder 1.

[0030] Finally, the most important contribution of the present invention is that the first connection end M-1 of each connecting wire M and the second connection end N-1 of the power line N are both extended into the insulating cylinder 1 for stacking, and then the locking insulating column 3 is rotated downward to clamp the stacked first connection end M-1 and the second connection end N-1 to realize wiring in an orderly manner without being messy. Moreover, after wiring, the cooperation between the locking insulating column 3 and the insulating cylinder 1 can seal the connection, with a simple structure and high practicality.

[0031] The cooperation of the multiple insulating cylinders 1 and the locking insulating columns 3 of the present invention ensures that the connection or removal of each first connection end M-1 and the second connection end N-1 will not be affected, and can be carried out in an orderly manner without any mess.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
