Description

Technical Field

[0001] The utility model relates to the technical field of slip rings, in particular to a slip ring for a water pump motor based on waterproof protection technology. Background Art

[0002] A slip ring is also called a conducting ring, a slip ring, a current collecting ring, a bus bar ring, etc. It can be used in any electromechanical system that requires continuous rotation while transmitting power and signals from a fixed position to a rotating position. The slip ring can improve the system performance, simplify the system structure, and avoid wire sprains during rotation;

[0003] The existing Chinese patent document CN201720454265.8 discloses a slip ring for a motor, which includes a slip ring body. Two wires are led out from the slip ring body. Among them, a section of protective sleeve is injection-molded outside the part of the two wires close to the slip ring body. The slip ring body includes a plastic support body, and a first slip ring and a second slip ring are arranged on the plastic support body. The two wires are electrically connected to the first slip ring and the second slip ring respectively. The above-mentioned slip ring for a motor is injection-molded with a protective sleeve outside the wire of the slip ring. During installation, the slip ring can be directly assembled onto the motor without potting. It not only has a simple structure and is easy to implement, but also greatly simplifies the installation process of the slip ring and reduces the production cost on the premise of ensuring the working reliability of the slip ring.

[0004] However, the above patent has certain defects in use. During the operation of a traditional water pump motor, due to the relatively harsh external environment, it will come into contact with water. And this slip ring is not provided with a protection device, so it is easy to splash water and other impurities onto the surface of the slip ring, which will cause sparks, affect the performance of the slip ring, exacerbate the wear of the device, require frequent maintenance, and reduce the service life.

[0005] Therefore, a slip ring for a water pump motor based on waterproof protection technology is proposed here to solve the above problems. Summary of the Utility Model

[0006] In order to overcome the deficiencies of the prior art, the utility model provides a slip ring for a water pump motor based on waterproof protection technology.

[0007] The utility model is realized by adopting the following technical solutions:

[0008] A slip ring for a water pump motor based on waterproof protection technology includes a slip ring body. The slip ring body includes an injection-molded body, slip rings, and pins. There are multiple slip rings, and the slip rings are fixed on the outer surface of the injection-molded body. The pins are fixed on the side wall of the injection-molded body. The number of pins is the same as the number of slip rings. The pins are connected to the slip rings inside the injection-molded body. A protective shell is arranged outside the slip ring body, and the slip ring body is placed inside the protective shell;

[0009] The protective case is a rectangular shell with a hollow interior. There are openings at the left and right ends of the protective case, and inspection covers are provided at the openings of the protective case. The inspection covers are divided into a front inspection cover and a rear inspection cover. Mounting blocks are provided on the side walls at the openings of the protective case, and the inspection covers are fixedly connected to the protective case through studs.

[0010] The inspection cover is provided with wire inlet and outlet holes.
