Embodiment 1

[0031] This embodiment provides a waterproof sleeve for water-immersed motor wiring, such as figure 1 As shown, it includes the electromagnetic wire penetration cylinder 1 and the connector protection cylinder 2. Both the magnet wire penetration cylinder 1 and the joint protection cylinder 2 are made of high-strength waterproof insulating rubber material, which has good insulation performance and can maintain a stable state for a long time in water , will not expand due to moisture, the electromagnetic wire penetration tube 1 is a tapered cylindrical structure, including a small diameter end and a large diameter end, and a through small hole 11 opened inside it, and the joint protection tube 2 is cylindrical structure, which includes a connection end and a free end, and a large through-hole 21 opened inside, and the electromagnetic wire penetration cylinder 1 and the joint protection cylinder are formed into one through the fixed connection between the large-diameter end and th...

Embodiment 2

[0035] For the three star-point connection electromagnetic wires, this embodiment provides another implementation of the waterproof sleeve for the connection of the water-immersed motor, such as figure 2 As shown, the number of electromagnetic wire penetration cylinders 1 is 2, the number of joint protection cylinders 2 is 1, the number of large holes 21 in the joint protection cylinder 2 is 1, and the number of two electromagnetic wire penetration cylinders 1 is fixed side by side. The large-diameter end of the joint protection tube 2 is connected to the connection end of the joint protection tube 2, and two small holes 11 and one large hole 21 are correspondingly set through. It has a cylindrical structure, and the other end is a tapered cylindrical structure, and a penetrating tail tube channel 31 is provided in the tail tube 3. The outer diameter of the cylindrical end of the tail tube 3 and the inner diameter of the free end of the joint protection tube 2 form a clearance...

Embodiment 3

[0038] For the connection of three electromagnetic wires and one cable, this embodiment provides another implementation of the waterproof sleeve for wiring of a water-immersed motor, such as image 3 As shown, the number of electromagnetic wire penetration cylinders 1 is three, the number of joint protection cylinders 2 is one, the number of large holes 21 in the joint protection cylinder 2 is three, and the three electromagnetic wire penetration cylinders 1 are fixed side by side and the three The large-diameter end of the connector is connected to the connection end of the joint protection cylinder 2, and the three small holes 11 are respectively connected with the three large holes 21.

[0039] The method of use is as follows: the three electromagnetic wires are respectively inserted into the small hole 11 through the small diameter end of the electromagnetic wire into the cylinder 1, and respectively penetrated through the small hole 11 to the large hole 21 of the joint pro...

Abstract

The invention provides a waterproof sleeve for water-immersed motor wiring and a using method of the waterproof sleeve. The waterproof sleeve for the water-immersed motor wiring comprises electromagnetic wire penetration cylinders and a joint protection cylinder, each electromagnetic wire penetrating cylinder is of a conical cylinder-shaped structure, and a small through hole channel is formed inthe electromagnetic wire penetrating cylinder. The joint protection cylinder is of a straight cylinder structure, a plurality of large through hole channels are formed in the joint protection cylinder, and the plurality of electromagnetic wire penetrating cylinders are fixed side by side and are connected with the joint protection cylinder. The small through hole channels correspond to the large through hole channels, when the waterproof sleeve is in use, an electromagnetic wire penetrates through the electromagnetic wire penetrating cylinder, a cable penetrates through the large hole channel,a joint is welded and then placed in the joint protection cylinder, and then the electromagnetic wire penetrating cylinder and the joint protection cylinder are sealed without needing to wind a self-adhesive tape. The joint part is small in size and is attractive, meanwhile, the problem of electric leakage caused by the fact that the winding quality cannot be guaranteed is solved, and higher safety is achieved.

Description

technical field [0001] The invention relates to the field of motor wiring, in particular to a waterproof sleeve for submerged motor wiring and a use method thereof. Background technique [0002] In the use of water pumps, there are often cable joints. The current treatment method for the joints is generally to wrap 3 to 5 layers of PVC special waterproof tape on the welded joints, wrap the burrs, and then use a self- The adhesive tape is tightly wound 7-9 layers on the periphery of the PVC special waterproof tape, and finally wraps two layers of PVC special waterproof tape on the periphery of the self-adhesive tape as a protective layer. Due to the winding of multi-layer tapes, this joint treatment method will make The diameter of the joint is too large, and because the winding is manual, the quality of the wrapping cannot be guaranteed. In practical applications, the existing self-adhesive tapes all have the problem of swelling after being exposed to water and moisture, whi...
