Description

Technical Field

[0001] This utility model relates to a power line support component. Background Technology

[0002] A power line support component that supports the power line of the motor (see, for example, Patent Document 1).

[0003] Patent Document 1: Japanese Patent Application Publication No. 2014-128095

[0004] If such a power line support component is fixed to the motor housing using bolts or other fasteners, deformation may occur during assembly. If the power line support component is fixed to the housing in a deformed state, its durability may be reduced. Utility Model Content

[0005] Therefore, the purpose of this invention is to provide a power line support component that suppresses the reduction of durability.

[0006] The above objective can be achieved by a power line support member, which includes: a support portion for supporting the power line of the motor; and a fixing portion that is inserted into a recess in the motor housing and fixed therein by thermosetting resin filled in the recess.

[0007] According to this invention, a power line support component that suppresses the reduction of durability can be provided. Attached Figure Description

[0008] Figure 1 This is an explanatory diagram of the power line support component.

[0009] Explanation of reference numerals in the attached figures

[0010] 10…Power line support component; 14…Support hole (support part); 16…Fixed part; 116…Power line; 120…Housing; 122…Recess; W…High viscosity varnish (thermosetting resin). Detailed Implementation

[0011] Figure 1This is an explanatory diagram of the power line support member 10. The power line support member 10 has a flat plate portion 12, a support hole 14, a fixed portion 16, an inlet hole 17, and an opening 18. The power line support member 10 is made of resin. The flat plate portion 12 is plate-shaped. A portion of the support hole 14 extends through the thickness of the flat plate portion 12. The power line 116 passes through the support hole 14. The power line 116 is a copper busbar, but is not limited to this. One end of the power line 116 is conductively connected to the power line 112 via a welding portion 114. The power line 112 is connected to the stator-side terminal 110 of the motor 100. The other end of the power line 116 is fixed to the terminal block 118 by a bolt 119.

[0012] In addition, Figure 1 Only one pair of power lines 112 and 116 is shown, but in reality, there are three pairs: U-phase, V-phase, and W-phase. Therefore, the power line support member 10 is provided with three support holes 14 for the three power lines 116 to pass through respectively. Thus, the support holes 14 of the power line support member 10 support the power lines 116. The support holes 14 are an example of a support portion. Furthermore, for these motors 100 and power line support members 10, for example, when used in a vehicle, even if vehicle vibrations or vibrations from the engine are transmitted to the power lines 116, they are stably supported by the power line support member 10.

[0013] The fixed portion 16 protrudes downward from the flat portion 12. The fixed portion 16 is inserted into a recess 122 formed in the housing 120 of the motor 100. The housing 120 is, for example, made of metal. The outer diameter of the fixed portion 16 is smaller than the inner diameter of the recess 122. An inlet hole 17 is formed on the inner side of the fixed portion 16. Furthermore, the outer diameter of the fixed portion 16 and the inner diameter of the inlet hole 17 are tapered, gradually decreasing downwards. A grid-like opening 18 is provided at the front end of the fixed portion 16. The fixed portion 16 and the recess 122 are filled with a high-viscosity varnish W, an example of a thermosetting resin. The fixed portion 16 is fixed to the recess 122 by the high-viscosity varnish W. The high-viscosity varnish W is a fluid at room temperature and has thermosetting properties.

[0014] When the fixing part 16 is fixed to the recess 122 using high-viscosity varnish W, the high-viscosity varnish W at room temperature is filled into the inlet hole 17 while the fixing part 16 is inserted into the recess 122. As a result, the high-viscosity varnish W flows through the opening 18 between the front periphery of the fixing part 16 and the inner peripheral surface of the recess 122. This fills the recess 122 with high-viscosity varnish W. Then, by heating the high-viscosity varnish W, it is thermosetting, thus fixing the fixing part 16 to the recess 122.

[0015] By using high-viscosity varnish W as described above, since the high-viscosity varnish W is fluid at room temperature during assembly, deformation of the power line support member 10 is suppressed. This suppresses any decrease in the durability of the power line support member 10. Furthermore, by heat-curing the high-viscosity varnish W, the fixed portion 16 and the recess 122 are firmly fixed, suppressing the transmission of vibration to the power line 116.

[0016] The recess 122 is a threaded hole. Therefore, high-viscosity varnish W enters and cures between the threaded grooves formed on the inner circumferential surface of the recess 122, thereby creating a wedge-like effect relative to each vibration direction. This also suppresses the transmission of vibration to the power line 116.

[0017] Furthermore, compared to using metal components such as bolts to fix the power line support component 10 to the housing 120, weight reduction can be achieved. The recess 122 is not limited to a threaded hole; any hole with a bottom is acceptable.

[0018] The embodiments of the present utility model have been described in detail above, but the present utility model is not limited to this specific embodiment. Various modifications and alterations can be made within the scope of the spirit of the present utility model as described in the technical solution.
