Description

Technical Field

[0001] This utility model relates to the field of glue-filled motor technology, and in particular to a glue-filled motor cable. Background Technology

[0002] Encapsulating adhesive needs to be injected into the motor to seal the stator windings. To avoid adhesive leakage, the sealing performance of the structure is required to be high.

[0003] To simplify the structure, the assembly of the back cover and housing of the glue-dispensing motor can adopt an internal snap-fit ​​mechanism, which is relatively convenient for assembly. However, this structure is not conducive to the installation of cables. The design of the cable-housing fit structure is unreasonable and prone to glue leakage, which needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a glue-filled motor cable that ensures ease of assembly and reduces the risk of glue leakage.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A glue-filled motor cable, used in assembly with a glue-filled motor's rear cover and housing, includes: a sheath and a cable core penetrating the sheath; the rear cover is disposed on the top of the housing; a ring groove is recessed at the top edge of the housing; a cover ring extends downward into the ring groove at the edge of the rear cover; a U-shaped groove extending below the ring groove is recessed in the top of the housing; a cylindrical filling portion extending through the U-shaped groove into the housing is concentrically disposed on the sheath; a clearance portion is disposed on the cover ring above the U-shaped groove; an arc-shaped pressure plate extending downward to the cylindrical filling portion is disposed in the clearance portion; a first clamping portion extending downward along the outer wall of the housing and a second clamping portion extending downward along the inner wall of the housing are disposed on the cylindrical filling portion; a third clamping portion extending upward along the outer wall of the arc-shaped pressure plate and a fourth clamping portion extending upward along the inner wall of the arc-shaped pressure plate are disposed on the cylindrical filling portion.

[0007] The inner wall of the cover ring is provided with a groove, and the groove is provided with a rib corresponding to the groove.

[0008] The back cover, the arc-shaped pressure plate, and the cover ring are integrated into one structure.

[0009] The wall thickness of the arc-shaped pressure plate is less than the wall thickness of the top of the housing.

[0010] The third clamping part is connected to the first clamping part, and the thickness of the third clamping part is greater than the thickness of the first clamping part to form a step at the connection.

[0011] The top of the third clamping part and the fourth clamping part are respectively provided with a plane that contacts the bottom surface of the rear cover.

[0012] The beneficial effects of this utility model are as follows: A glue-filled motor cable, through the cooperation of the cylindrical filling part and the U-shaped groove, enables quick positioning during assembly, and after the rear cover is installed, the cylindrical filling part is pressed and secured by the arc-shaped pressure plate, resulting in a stable structure and convenient assembly. The first and second clamping parts are used to clamp the side wall of the housing, and the third and fourth clamping parts are used to clamp the arc-shaped pressure plate, which improves the sealing effect and reduces the risk of glue leakage.

[0015] Figure 3 yes Figure 2 A schematic diagram of the structure of the middle casing. Detailed Implementation

[0016] The following is combined Figures 1-3 The technical solution of this utility model will be further illustrated through specific embodiments.

[0017] like Figure 1 and Figure 2 The shown glue-filled motor cable 100, when assembled with the glue-filled motor rear cover 300 and housing 200, includes: a sheath 110 and a cable core 120 passing through the sheath 110. The rear cover 300 is located on the top of the housing 200. The top edge of the housing 200 is recessed with a ring groove 210. The edge of the rear cover 300 is provided with a cover ring 310 extending downward into the ring groove 210. The fit is tight, the assembly is quick, and the sealing is good.

[0018] In this embodiment, the inner wall of the cover ring 310 is provided with a groove 320, and the annular groove 210 is provided with a rib 220 corresponding to the groove 320. The groove 320 and the rib 220 cooperate to lock the cover ring 310 and improve the stability after assembly.

[0019] like Figure 3 As shown, the top of the housing 200 is recessed and has a U-shaped groove 230 extending below the annular groove 210, as... Figure 1 As shown, the sheath 110 is concentrically provided with a cylindrical filling part 111 extending into the housing 200 through a U-shaped groove 230. The cylindrical filling part 111 and the U-shaped groove 230 cooperate to achieve quick positioning during assembly, resulting in a stable structure and convenient assembly.

[0020] In this embodiment, the cover ring 310 is provided with a clearance portion located above the U-shaped groove 230. An arc-shaped pressure plate 330 extending downwards to the cylindrical filling portion 111 is provided within the clearance portion. After the rear cover 300 is installed, the arc-shaped pressure plate 330 is used to compress and solidify the cylindrical filling portion 111, improving its radial stability. The rear cover 300, the arc-shaped pressure plate 330, and the cover ring 310 adopt an integrated structure, requiring no assembly and ensuring high structural reliability.

[0021] like Figure 1 As shown, the cylindrical filling part 111 is provided with a first clamping part 115 extending downward along the outer wall of the housing 200 and a second clamping part 116 extending downward along the inner wall of the housing 200, and the first clamping part 115 and the second clamping part 116 are used to elastically clamp the side wall of the housing 200.

[0022] The cylindrical filling part 111 is provided with a third clamping part 113 extending upward along the outer wall of the arc-shaped pressure plate 330 and a fourth clamping part 114 extending upward along the inner wall of the arc-shaped pressure plate 330. The third clamping part 113 and the fourth clamping part 114 are used to elastically clamp the arc-shaped pressure plate 330, which improves the sealing effect and reduces the risk of glue leakage.

[0023] In this embodiment, the cylindrical filling part 111, the first clamping part 115, the second clamping part 116, the third clamping part 113 and the fourth clamping part 114 adopt an integrated PVC structure and are generated by mold, resulting in high production efficiency.

[0024] like Figure 2 As shown, the wall thickness of the arc-shaped pressure plate 330 is less than the wall thickness of the top of the housing 200. In addition, the third clamping part 113 is connected to the first clamping part 115. The thickness of the third clamping part 113 is greater than the thickness of the first clamping part 115 to form a step 112 at the connection. Through the cooperation of the step 112 with the bottom surface of the annular groove 210, a seal is formed, further reducing the risk of glue leakage.

[0025] like Figure 1 As shown, the second clamping part 116 is connected to the fourth clamping part 114, and the wall thickness is uniform, the structure is reliable, and the tensile strength of the sheath 110 is ensured.

[0026] Furthermore, the tops of the third clamping part 113 and the fourth clamping part 114 are respectively provided with a plane that contacts the bottom surface of the rear cover 300. After the rear cover 300 is installed, the bottom surface of the rear cover 300 contacts the planes at the top of the third clamping part 113 and the fourth clamping part 114 to achieve tight pressing of the third clamping part 113 and the fourth clamping part 114, preventing the third clamping part 113 and the fourth clamping part 114 from loosening, and also preventing the rotation of the cylindrical filling part 111, which helps to reduce the risk of glue leakage.

[0027] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
