The substantially circular arc of the outer surface of the slot 5,5,5 and insertion part 20 of the substantially arc-shaped of the inner peripheral surface of above-mentioned shell 1 The slot 25,25,25 of shape is opposed and reliably holds three conducting wires 30,30,30.
In addition, as shown in Figures 2 and 3, in the upside of the slot 5,5,5 of the substantially arc-shaped of the inner surface of above-mentioned shell 1 Substantially rectangular recess 17 is equipped between part 5a, 5a, 5a and part 5b, 5b, 5b of downside.As shown in figure 3, the recess 17 Depth is greater than the depth of the substantially slot 5,5,5 of arc-shaped, the inner surface not contact wire 30,30,30 of recess 17.In addition, such as Fig. 1 With shown in Fig. 4, be the part of the substantially upside of the slot 25,25,25 of arc-shaped in the section of the outer surface of above-mentioned insertion part 20 Substantially rectangular recess 27 is equipped between 25a, 25a, 25a and part 25b, 25b, 25b of downside.As shown in figure 3, the recess 27 Depth be greater than the depth of the substantially slot 25,25,25 of arc-shaped, the inner surface not contact wire 30,30,30 of recess 27.It utilizes The recess 17 and 27 forms partition gap 37, the water that will be flow down along conducting wire 30,30,30 using the partition gap 37 Truncation, prevents water from invading inside.
In addition, the two sides in the width direction of above-mentioned through hole 2 are provided with work in holding section as depicted in figs. 1 and 2 For an exemplary substantially rectangular connecting hole 6,6.As can be seen from FIG. 2, above-mentioned connecting hole 6,6 is located at the inner surface of shell 1 The two sides on the top of side.On the other hand, as shown in Figure 1, two of the top in the side of the outer surface of above-mentioned insertion part 20 Side is provided with an exemplary substantially rectangular engaging protuberances 26,26 as holding section.By the connecting hole 6,6 with engage it is convex Engaging of the portion 26,26 on the perforation direction of through hole 2, avoids insertion part 20 from taking off downwards from the through hole 2 of shell 1 It falls.
In addition, the holding section for being set to shell 1 and insertion part 20 is not limited to above-mentioned connecting hole 6 and engaging protuberances 16, It is also possible to engaging protuberances and connecting hole, in addition, the shape of holding section is not limited to rectangle, as long as can engage, can be any Shape.
In addition, having in the end of 10 side of lower part of above-mentioned shell 1 and bloating downwards as shown in Fig. 2, Fig. 3, Fig. 5, Fig. 6 Protrusion 11, the water for guiding the outer surface along shell 1 to fall downwards using the protrusion bloated downwards 11 is from shell 1 On fall, avoid it from invading in shell 1.More specifically, as shown in fig. 6, leaning on shell using the protrusion 11 bloated downwards The part 11a of the periphery surface side of body 1 makes end 11c quilt of the water droplet W fallen along the outer peripheral surface of shell 1 towards bellying 11 It guides and separates and fall with shell 1 from end 11c.On the other hand, since the protrusion 11 that bloats downwards is by shell 1 The part 11b of inner peripheral surface side becomes from the 11c of end and rises curved surface, and therefore, water droplet W rises along the part 11b of inner peripheral surface side Overcome gravity, water droplet W is not easily accessible in shell 1.Therefore, can using the protrusion bloated downwards 11 prevent water droplet into Enter the inner peripheral surface side to shell 1.
In addition, it is arc-shaped that the protrusion 11 bloated downwards, which is not limited to section, being also possible to section is elliptical shape, section It is hyperbolic shape etc. for parabolic shape, section, as long as being bent and cross sectional shape outstanding, then can be arbitrary shape.
In addition, the protrusion 11 of above-mentioned bulging is linked to be ring-type in the entire lower end surface of shell 1, and surround conducting wire 30,30,30.
In this way, the protrusion 11 of cricoid bulging is seamless, and surrounds all conducting 30,30,30, it therefore, can be reliably It prevents the water declined along the outer surface of shell 1 from invading the inside of shell 1, and water droplet W can be guided downwards from shell 1 On fall.
On the other hand, as shown in Figure 1, the length on the direction that through hole 2 extends of the height of above-mentioned shell 1, i.e. shell 1 Degree be longer than insertion part 20 on the direction that above-mentioned through hole 2 extends length (that is, insertion part 20 shown in the arrow X Direction of insertion on length), as shown in Figure 3, Figure 5 and Figure 6, inner peripheral surface and insertion section using the lower part 10 of above-mentioned shell 1 The lower end surface 21 of part 20 forms recess portion 8.
Therefore, as shown in fig. 6, when keeping above-mentioned recess portion 8 downward, it is attached to water droplet W on the outer peripheral surface of shell 1 almost Gravity will not be overcome along the inner surface of recess portion 8 and rise.Therefore, because the presence of above-mentioned recess portion 8, can more reliably make water Drop W drips down without the inside for invading shell 1.
In the bushing of above structure, shown in arrow X as shown in figure 1, conducting wire 30,30,30 is being kept or is being installed on shell An exemplary section as the first maintaining part for the inner surface of the through hole 2 of body 1 is the shape of the substantially slot 5,5,5 of arc-shaped It is 25,25,25 guide of slot of substantially arc-shaped by an exemplary section as the second maintaining part for insertion part 20 under state Line 30,30,30 guides, and insertion part 20 is inserted into the through hole 2 of shell 1, by the engaging protuberances 26 of insertion part 20 It is sticked in the connecting hole 6 of shell 1 and insertion part 20 is assembled in shell 1.
At this point, since above-mentioned shell 1 and insertion part 20 are made of resin, the section of insertion part 20 is substantially Frictional resistance caused by the insulating bag overlay film of the conducting wire 30 of the slot 25,25,25 of arc-shaped is not too big, and insertion part 20 can be suitable It freely is assembled into the through hole 2 of shell 1.
If shell and insertion part are rubber system, then due to the elasticity of rubber and its relative to the frictional resistance of conducting wire, Sometimes insertion part can not be easily inserted into shell.
Further, since above-mentioned insertion part 20 and shell 1 are integrated with the engaging of connecting hole 6 by engaging protuberances 26, Therefore, insertion part 20 will not be prominent to the lower section of shell 1 or falls off downwards.
In addition, above-mentioned conducting wire 30,30,30 by shell 1 through hole 2 inner surface and be inserted into the through hole 2 The outer surface of insertion part 20 is kept, and does not have seam in the outside of shell 1, therefore, can prevent from being attached to the outer of the shell 1 Water droplet etc. on circumferential surface invades in shell 1.
Therefore, water can be prevented to be immersed in the motor for having used the bushing.
In addition, above-mentioned first maintaining part and the second maintaining part are the slots 5,5,5 that such as section is substantially arc-shaped; 25, 25, therefore 25 i.e. curved recess portions seamlessly can reliably hold conducting wire 30,30,30.
In particular, in the first embodiment, due to the bending as the first maintaining part of the inner surface of above-mentioned shell 1 Recess portion an example, that is, section be the substantially outer surface of the slot 5,5,5 and above-mentioned insertion part 20 of arc-shaped conduct second One example, that is, section of the curved recess portion of maintaining part is that the slot 25,25,25 of substantially arc-shaped keeps three opposite each otherly Conducting wire 30,30,30, therefore, can pole reliably seamlessly hold three conducting wires 30,30,30.
Also, since these sections are that substantially the slot 5,5,5 of arc-shaped and section are the slot 25,25,25 of substantially arc-shaped It is accommodated in the non-jointed shell 1 in outside without being exposed to outside, therefore, water is not easy to invade these positions.
Also, also as shown in Fig. 2, Fig. 3, Fig. 5 and Fig. 6, since the end face of 10 side of lower part of above-mentioned shell 1 becomes downwards Therefore the protrusion 11 of bulging can guide downwards the outer surface along shell 1 to fall using the protrusion bloated downwards 11 Water fallen from shell 1 and avoid invading in shell.More specifically, as shown in fig. 6, utilizing the protrusion bloated downwards The part 11a of the 11 periphery surface side by shell 1 makes the water droplet W fallen along the outer peripheral surface of shell 1 towards bellying 11 End 11c is guided and separates and fall with shell 1 from end 11c, on the other hand, due to the protrusion 11 bloated downwards The inner peripheral surface side by shell 1 part 11b from the 11c of end become rise curved surface, therefore, water droplet W is along inner peripheral surface side 11b rising in part will overcome gravity, and water droplet W is not easily accessible in shell 1.
Therefore, water droplet can be reliably prevented using the protrusion bloated downwards 11 to enter in shell 1.
Also, the protrusion 11 of above-mentioned bulging is linked to be ring-type in the entire lower end surface of shell 1, and surround all conducting 30, 30,30, therefore, it is reliably prevented from the inside that shell 1 is invaded along the water of the outer surface decline of shell 1, and can Guidance water droplet W is fallen from shell 1 downwards.
In addition, the length on the direction that through hole 2 extends of the height of above-mentioned shell 1, i.e. shell 1 is longer than above-mentioned insertion The length on the direction that through hole 2 extends of component 20, as shown in Figure 3, Figure 5 and Figure 6, due to using under above-mentioned shell 1 The inner peripheral surface in portion 10 and the lower end surface 21 of insertion part 20 form recess portion 8, therefore, when making the recess portion 8 downward as illustrated in fig. 6 When, the water droplet W being attached on the outer peripheral surface of shell 1 hardly overcomes gravity along the inner surface of recess portion 8 and rises.Therefore, Due to the presence of above-mentioned recess portion 8, water droplet W can be more reliably set to drip down without the inside for invading shell 1.
In addition, as shown in Figures 2 and 3, the upper of the slot 5,5,5 of the substantially arc-shaped of the inner surface of above-mentioned shell 1 is arranged in The depth of recess 17 between part 5a, 5a, 5a of side and part 5b, 5b, 5b of downside is greater than substantially circular arc as shown in Figure 3 The depth of the slot 5,5,5 of shape, the inner surface not contact wire 30,30,30 of recess 17, also, be arranged in above-mentioned insertion part 20 Outer surface section be substantially part 25a, 25a, 25a of the upside of the slot 25,25,25 of arc-shaped and downside part The depth of recess 27 between 25b, 25b, 25b is greater than the depth of the slot 25,25,25 of substantially arc-shaped, recess 27 as shown in Figure 3 Inner surface not contact wire 30,30,30.Therefore, partition gap 37 is formed using the recess 17 and 27, even if if water Flow down along conducting wire 30,30,30, also water can be truncated using the partition gap 37, can prevent water from invading inside.
