The objects, features and advantages of the present invention will be further described with reference to the accompanying drawings.
Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 to 4, an embodiment of the present invention is provided, a water pump wiring installation structure, including a housing 1 and a power line 2 extending from the inside to the outside of the housing 1. A slotted hole 3 is arranged on the shell 1, and the inner diameter of the outer end of the slotted hole 3 is larger than that of the inner end, so that the section of the slotted hole 3 is in an approximately trapezoidal irregular shape.
The inner cavity of the slot hole 3 is provided with a sealing sleeve 4, and the sealing sleeve 4 can be made of rubber material or other materials with better elasticity and water resistance. The power cord 2 runs through the sealing sleeve 4 and extends to the outside of the shell 1, and the sealing sleeve 4 is tightly wrapped on the surface of the power cord 2, so that the surface of the power cord 2 is tightly contacted with the sealing sleeve 4, and water leakage is avoided.
The outer wall surface of the sealing sleeve 4 is provided with a circle of annular bulge part clamped with the inner wall surface of the slotted hole 3, the inner wall of the inner end of the slotted hole 3 is matched with the annular bulge part of the sealing sleeve 4, the inner wall surface of the slotted hole 3 is provided with a bearing part matched with the annular bulge part, and when the sealing sleeve 4 is installed in the slotted hole 3, the annular bulge part on the surface of the sealing sleeve 4 is in close contact with the bearing part on the inner wall surface of the slotted hole 3, so that the sealing sleeve 4 is sealed with the shell 1, and water leakage.
