Description

Technical Field

[0001] The utility model relates to the technical field of motor waterproofing, and particularly relates to a novel motor cable sheath structure. Background Art

[0002] For motors that need to meet the IP68 requirements for waterproof and dustproof, usually the cables on the motor are led out from the inside of the motor by means of cable waterproof connectors. For motors with compact external dimensions requirements, the existing waterproof connectors are relatively large in size, and there is not enough space on the motor to install the waterproof connectors. Usually, only a simple rubber sleeve is used to protect the cable outer skin, which cannot meet the protection requirements of IP68. Therefore, we propose a novel motor cable sheath structure to solve the above problems. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the disadvantages in the prior art that the existing waterproof connectors are relatively large in size, there is not enough space on the motor to install the waterproof connectors, and usually only a simple rubber sleeve is used to protect the cable outer skin, which cannot meet the protection requirements of IP68, and to propose a novel motor cable sheath structure.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A novel motor cable sheath structure includes a sheath main body made of rubber material. A wire passing hole is provided on the sheath main body, and one end of the sheath main body is a baffle, and the other end of the sheath main body is provided with an inclined angle. Moreover, a groove is opened on the sheath main body, and multiple sealing lines are arranged in the groove. The sealing lines and the groove form a lip-shaped structure, and the sealing performance between the sheath main body and the motor end cover is improved through the lip-shaped structure and the wire outlet hole on the motor end cover that matches it.

[0006] As a preferred technical scheme of the utility model, a reinforcing ring is arranged at one end of the wire passing hole where it is located on the baffle, which improves the strength of the outer end of the wire passing hole, and at the same time improves the stability after the cable is inserted, and reduces the shaking of the cable.

[0007] As a preferred technical scheme of the utility model, a slot is arranged at the end of the sheath main body away from the baffle, and the slot is located in the middle of the outer end face of the sheath main body. The arrangement of the slot makes it more convenient to press the sheath main body into the motor end cover.

[0008] As a preferred technical scheme of the utility model, the number of the sealing lines is two to five, and each sealing line is wound around the inside of the groove in a ring shape, and the sealing degree between the sheath main body and the motor end cover is further improved through the sealing lines.

[0009] The beneficial effects of the utility model are:

[0010] A new cable sheath, through the cooperation of a multi-layer lip-shaped structure on the sheath body and the wire outlet hole on the motor end cover, and at the same time, the front and rear end faces of the sheath body are fitted with the end face of the end cover, so as to realize the protection at the cable. The sheath body can be directly inserted into the wire outlet hole on the end cover, with simple installation and compact structural dimensions. At the same time, this structure can adjust the number of wire outlet holes on the sheath according to the required number of cables, and can also meet the application scenarios of multiple cables.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0016] Refer to Figures 1-3 , a new type of motor cable sheath structure, including a sheath body 2, the sheath body 2 is made of rubber material, a threading hole 25 is provided on the sheath body 2, the number of the threading holes 25 is determined according to the number of cables 3 to be threaded, and a reinforcing ring 27 is provided at one end of the threading hole 25 located on the baffle 21 to improve the strength of the outer end of the threading hole 25, and at the same time improve the stability after the cable 3 is inserted, and reduce the shaking of the cable 3;

[0017] Among them, one end of the sheath body 2 is a baffle 21, the baffle 21 is integrally formed with the sheath body 2, and at the same time, the baffle 21 is adapted to the outer end of the wire outlet hole of the sheath body 2 on the motor end cover 1, and the baffle 21 is fitted with it after installation;

[0018] Secondly, the other end of the sheath body 2 is provided with an inclined angle 24. The setting of the inclined angle 24 facilitates the installation of the sheath body 2 in the wire outlet hole of the motor end cover 1. A groove 22 is formed on the sheath body 2, and a plurality of sealing lines 23 are arranged in the groove 22. The number of the sealing lines 23 is two to five. Each sealing line 23 is wound annularly inside the groove 22. The sealing degree between the sheath body 2 and the motor end cover 1 is further improved through the sealing lines 23. The sealing lines 23 and the groove 22 form a lip-shaped structure, and the sealing performance between the sheath body 2 and the motor end cover 1 is improved through the lip-shaped structure and the wire outlet hole adapted to the motor end cover 1.

[0019] Furthermore, a slot 26 is arranged at one end of the sheath body 2 away from the baffle 21. The slot 26 is located in the middle of the outer end face of the sheath body 2. The setting of the slot 26 makes it more convenient to press the sheath body 2 into the motor end cover 1. When inserting, the tail end of the sheath body 2 has more moving space for inward extrusion.

[0020] In this embodiment: As Figure 3 shown, a wire outlet hole adapted to the sheath body 2 is formed on the motor end cover 1. Through the cooperation of the multi-layer lip-shaped structure on the sheath body 2 and the wire outlet hole on the motor end cover 1, and at the same time, the front and rear end faces of the sheath body 2 are attached to the faces of the motor end cover 1, the protection of the cable 3 is realized.

[0021] The sheath body 2 can be directly inserted into the wire outlet hole on the motor end cover 1, with simple installation and compact structural dimensions. At the same time, this structure can adjust the number of wire outlet holes on the sheath body 2 according to the required number of cables 3, and can also meet the application scenarios of multiple cables 3;

[0022] This structure is simple and reliable, with concise and compact dimensions, which can maximize the reduction of the motor volume. Using one part can achieve the effect that usually requires 3 parts. The cost is about 50% lower than the usual structure, and at the same time, the protection effect of IP68 can be achieved.

[0023] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
