On the other hand, the auxiliary holding section 143 of rotation angle sensor be disposed on the lower, outer perimeter edge of stator 21, the main holding section 142 of rotation angle sensor and vehicle fixation side holding section 240 arranging between position separately.
Specifically, the main holding section 142 of rotation angle sensor is by the main holding section 142A(142A1 of pair of connectors side rudder angle transducer, the 142A2 that arrange in the lower, outer perimeter of stator 21) and the main holding section 142B(142B1 of pair of connectors separation side rotation angle sensor, 142B2) totally 4 holding sections form.
The main holding section 142A(142A1 of pair of connectors side rudder angle transducer, 142A2) in the lower, outer perimeter of stator 21, be disposed in the position, both sides (with reference to Fig. 6) of the Width of installation of sensors flange part 41 with state opposite one another.
The main holding section 142B(142B1 of pair of connectors separation side rotation angle sensor, 142B2) be disposed in and the main holding section 142A(142A1 of pair of connectors side rudder angle transducer, 142A2 in the opposition side separating with stator side connector 24 across through hole H respectively) roughly opposed position (with reference to Fig. 6) of difference.
In addition, in near of the main holding section 142B of connector separation side rotation angle sensor,, two outsides of the Width of the main holding section 142B of connector separation side rotation angle sensor, are extruded with the outstanding wall 145 of guiding for the main holding section 142B of guidance connector separation side rotation angle sensor.
Part on the periphery edge of the bottom surface of the stator 21 in rotary connector 10, between the main holding section 142A of connector side rudder angle transducer and the main holding section 142B of connector separation side rotation angle sensor, in other words, on periphery edge, the bottom surface of stator 21, with the two end portions of the straight line that stator side connector 24 is linked up with through hole H with the vertical vertical direction of the mode of intersecting at through hole H place, as shown in Figure 6, possess respectively jut close quarters Z, outstanding multiple juts are intensive at described jut close quarters Z downward.
At jut close quarters Z, at least outstanding vehicle fixation side holding section 240, sensor localization pin 248(248a, the 248b of being provided with) and vehicle fixation side locator protrusions portion 148 as 3 juts, in addition also the outstanding connector side rudder angle transducer that is provided with is assisted holding section 143.
The rotary connector 10 of said structure can play following effect.
In the rotary connector 10 of present embodiment, as shown in Fig. 3, Fig. 4 and Fig. 6, as mentioned above, the auxiliary holding section 143 of rotation angle sensor be disposed on the periphery edge of bottom of stator 21, the main holding section 142 of rotation angle sensor and vehicle fixation side holding section 240 arranging between position separately, therefore, can rotary connector be fixed on to not shown unit switch with excellent integraty, and, with excellent integraty, rotation angle sensor 700 is installed.
Specifically, about the rotary connector 10 of present embodiment, as mentioned above, part on the periphery edge of the bottom surface of stator 21, between the main holding section 142A of connector side rudder angle transducer and the main holding section 142B of connector separation side rotation angle sensor possesses jut close quarters Z, vehicle fixation side locator protrusions portion 148, vehicle fixation side holding section 240,248 at least 3 juts of sensor localization jut as outstanding downwards multiple juts under state adjacent one another are intensive in described jut close quarters Z(with reference to Fig. 6).
Like this, in the lower, outer perimeter edge of stator 21, be equipped with 240 and 2 of 3 vehicle fixation side holding sections vehicle fixation side locator protrusions portion 148 as car body side fixed component 200, and, be equipped with 4 main holding section 142(142A1 of rotation angle sensor, 142A2,142B1,142B2) and 2 sensor localization juts 248 as rotation angle sensor installation component 140.
Thus, on the lower, outer perimeter edge of stator 21, be formed with in circumferential at least part the jut close quarters Z that multiple juts are intensive.There are multiple juts due to intensive in such jut close quarters Z, therefore, at least in jut close quarters Z, cannot increase the configuration quantity of the main holding section 142 of rotation angle sensor, thereby cannot guarantee the space that arranges the main holding section 142 of rotation angle sensor for appending.
But, if jut close quarters Z do not exist be sticked in rotation angle sensor 700 for engaging the member of rotation angle sensor 700, cannot be on the periphery edge of stator 21 balance well and stably will engage rotation angle sensor 700 and engage, thereby produce the such problem of the stator 21 that cannot guarantee rotary connector 10 and the excellent integraty of rotation angle sensor 700.
On the other hand, in the case of make in vehicle fixation side locator protrusions portion 148, vehicle fixation side holding section 240 and rotation angle sensor locator protrusions portion 248 adjacent in jut close quarters Z at least any staggers and is formed at other parts on the periphery edge of stator 21, can produce such problem: the stable fastening state between stator 21 and the unit switch of rotary connector 10 is impaired, or positioning precision between rotary connector 10 and rotation angle sensor 700 or between rotary connector 10 and unit switch is impaired.
On the other hand, the rotary connector 10 of present embodiment possesses the auxiliary holding section 143 of rotation angle sensor that snap portions is less than the snap portions of the main holding section 142 of rotation angle sensor, the auxiliary holding section 143 of described rotation angle sensor can the main holding section 142 of auxiliary rudder angle transducer engaging, thus, there is the jut close quarters Z of multiple juts even intensive, the auxiliary holding section 143 of rotation angle sensor also can be set.
Thus, rotary connector 10 does not just comprise that balance is disposed in the main holding section 142 of 4 rotation angle sensors of the periphery edge, bottom surface of stator 21 well, also comprise that 2 rotation angle sensors assist holding section 143, thereby can firmly and stably engage rotation angle sensor 700.
Therefore, in rotary connector 10, the stator of rotary connector 10 21 balances well and stably can be sticked in to unit switch, and, rotation angle sensor 700 balances well and stably can be sticked in to the stator 21 of rotary connector 10, therefore, can there is integraty with excellent positioning precision mutually rotary connector 10, rotation angle sensor 700 and unit switch are installed.
In addition, as mentioned above, main a pair of rotation angle sensor holding section 142A1,142A2 are arranged to configuration state in the both sides of the Width of installation of sensors flange part 41, therefore, main this pair of rotation angle sensor holding section 142A1,142A2 can be disposed in the direction that engaging power that the main holding section 142 of each rotation angle sensor engages with rotation angle sensor 700 repels each other mutually, thereby can utilize the main holding section 142 of rotation angle sensor of less configuration quantity rotation angle sensor 700 effectively and to be securely installed on to the stator 21 of rotary connector 10.
In addition, according to above-mentioned structure, as Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, the main holding section 142 of rotation angle sensor is loop-like by snap-latch piece 142a and a pair of supporting slice 142b structure as described above, thus, can be to form the main holding section 142 of rotation angle sensor by the such snap portions two supports structure of both end sides of a pair of supporting slice 142b supporting snap-latch piece 142a, on the other hand, the auxiliary holding section 143 of rotation angle sensor is configured to column by 1 supporting slice 143a and engaging tab 143b as described above, thus, can be to form the auxiliary holding section 143 of rotation angle sensor by 1 such snap portions single point supporting structure of supporting slice 142b supporting engaging tab 143a.
Like this, utilize the main holding section 142 of rotation angle sensor of 2 kinds of different engaging forms and the auxiliary holding section 143 of rotation angle sensor to engage rotation angle sensor 700, thus, can resist the various external force such as vibration to remain firmly fastening state.
And; as mentioned above; the main holding section 142 of ratio rotation angle sensor in the lower, outer perimeter edge of stator 21 is by the outstanding outstanding wall 145 of guiding that is provided with in position of outer circumferential side; therefore; can effectively protect the main holding section 142 of rotation angle sensor to avoid external force impact, thereby can prevent that the main holding section 142 of rotation angle sensor from departing from engaging surprisingly of rotation angle sensor 700.
Have again; in the main holding section 142 of multiple rotation angle sensors of periphery edge that is disposed in stator 21; compared with the main holding section 142A1 of connector side rudder angle transducer, 142A2; the main holding section 142B1 of pair of connectors separation side rotation angle sensor, 142B2 separate with stator side connector 24; described stator side connector 24 is outstanding downwards in the same manner from bottom surface and the main holding section 142 of rotation angle sensor of stator 21; therefore, the main holding section 142B1 of pair of connectors separation side rotation angle sensor, 142B2 are avoided external force impact by stator side connector 24 with physics mode protection.Therefore, particularly by the main holding section 142B(142B1 of pair of connectors separation side rotation angle sensor, 142B2) near possess the outstanding wall 145 of guiding, thus, even if the main holding section 142B of pair of connectors separation side rotation angle sensor, also can keep the fastening state with rotation angle sensor 700 securely.
In addition, according to above-mentioned structure, as shown in Fig. 3, Fig. 4 and Fig. 6, on tubular extension 130, a perisporium notch 133S is that narrow and small perisporium notch 133S forms and removes cam 131 to radially inner side depression in the circumferential lengths mode less than the circumferential lengths of another perisporium notch 133L, therefore, with week of base portion 134 upwards compared with the corresponding part 134L of another perisporium notch 133L, the week of base portion 134 rigidity around rotation with the corresponding part 134S of narrow and small perisporium notch 133S upwards high.
Therefore, by the week in base portion 134 upwards form base side engaging recessed part 135 with the corresponding part 134S of narrow and small perisporium notch 133S, thus, compared with the situation that forms base side engaging recessed part 135 with week in base portion 134 part 134L corresponding to another perisporium notch 133L upwards, can make sensor side engaging protuberance 712 engage securely (with reference to Figure 12) with base side engaging recessed part 135 around rotation.
Thus, the rotation of the rotor 31 of following with the rotating photo of steering wheel 600 can be engaged to the sensor side rotor portion 711 that snap portions that protuberance 712 fastens is passed to rotation angle sensor 700 reliably with sensor side via base side engaging recessed part 135, thus can by rotation angle sensor 700 error free detect the rotation information of steering wheel 600.
In addition, as shown in Figure 3 and Figure 7, make the pair of sensors locator protrusions 248a of portion of the lower, outer perimeter edge that is disposed in stator 21, the outstanding shape of a sensor localization jut 248a in 248b forms with circular cross sectional shape, and, make the outstanding shape of another sensor localization jut 248b with roughly OBL cross section formation, therefore, as shown in figure 11, there is not the situation that rotation angle sensor 700 is installed with incorrect posture with respect to the lower surface of stator 21, rotation angle sensor 700 can be installed under the state of posture that is positioned to regulation to the lower surface of stator 21.
In addition, in the rotary connector 10 of present embodiment, as mentioned above, a the 1st chimeric slot part 160S and another the 2nd chimeric slot part 160L in a pair of chimeric slot part 160 are formed with mutually different chimeric width, therefore, steering wheel 600 correctly can be installed on to rotary connector 10 with the mounting position of regulation.
Specifically, in the time of intercalation boss portion 610 in boss intercalation permission portion 38, suppose in the case of want with the chimeric poor form of the regulation with respect to should be chimeric the chimeric postures of 180 degree that overturn carry out chimeric, the 1st fitting projection 615S of circumferential lateral surface that is formed at boss portion 610 as shown in Figure 13 (a) with the axial direction of the 2nd chimeric slot part 160L in steering spindle forming in boss intercalation permission portion 38 on opposed, and the 2nd fitting projection 615L is opposed in the axial direction of steering spindle with the 1st chimeric slot part 160S as shown in Figure 13 (b).
, the width of the 2nd fitting projection 615L that the width of the 1st chimeric slot part 160S of present embodiment forms than the circumferential lateral surface in boss portion 610 is little, therefore, the 2nd fitting projection 615L cannot with the 1st chimeric slot part 160S chimeric (with reference to Figure 13 (b)).
With respect to this, in the rotary connector 10 of present embodiment, as mentioned above, the 1st chimeric slot part 160S and the 2nd chimeric slot part 160L form with mutually different chimeric width.; the 1st fitting projection 615S that is formed at the circumferential lateral surface of boss portion 610 be can be chimeric with the 1st chimeric slot part 160S width; and; the 2nd fitting projection 615L be can be chimeric with the 2nd chimeric slot part 160L width; therefore; as shown in Figure 8; by boss portion 610 in boss intercalation permission portion 38 when intercalation; in the case of want with the chimeric posture of regulation that should be chimeric carry out chimeric; as shown in the (a) and (b) of Figure 10, boss portion 610 can not firmly can be embedded in to boss intercalation permission portion 38 with the relative rotation with the chimeric posture of regulation.
Have again, can prevent boss portion 610 to be embedded in boss intercalation permission portion 38 with the chimeric posture of mistake.
And as shown in Figure 5, a pair of chimeric member 150 is disposed at respectively in week of boss intercalation permission portion 38 upwards across each side of the opposed part of the opposed regulation of through hole H.
According to above-mentioned structure, can balance well a pair of chimeric member 150 be disposed to the upwards position obtaining farthest separated from one another of week in boss intercalation permission portion 38, therefore, can utilize boss intercalation permission portion 38 firmly and intercalation boss portion efficiently 610.
And then, as Fig. 9 (a), (b) shown in, according to above-mentioned structure, guiding slot part 170 is formed as, along with the upstream side towards chimeric direction D, turn to axial upstream side, width becomes large gradually than the width of chimeric slot part 160, therefore, as shown in Figure 8, by boss portion 610 in boss intercalation permission portion 38 when intercalation, when fitting projection 615 beginnings are chimeric with chimeric member 150, can make fitting projection 615 by guiding slot part 170, width than the groove width of chimeric slot part 160 wide be directed away oral area 171(171S, 171L) and be easily embedded in guiding slot part 170.
And, as shown in figure 10, in a pair of chimeric member 150, temporarily be embedded in fitting projection 615 one side of guiding slot part 170 and groove side wall surface 172 butts one side of for example taper of chimeric slot part 160 by its guiding, therefore, as shown in the arrow D2 in the arrow D1 in Figure 10 (a) and Figure 10 (b), chimeric slot part 160 can smoothly and reliably guide fitting projection 615 towards chimeric slot part 160.
And, as shown in Figure 9, the oral area 171S that is directed away of the 1st guiding slot part 170S is compared to W with the A/F that is directed away oral area 171L of the 2nd guiding slot part 170L
171S/ W
171Lbe set as 0.97 times, and the 1st chimeric slot part 160S forming with mutually different chimeric width is compared to W with the embeded slot width of the 2nd chimeric slot part 160L
160S/ W
160Lbe set as 0.42 times, A/F compares W
171S/ W
171Lbe formed as becoming than embeded slot width and compare W
160S/ W
160Lgreatly.
Therefore, even if the width of the 1st chimeric slot part 160S is less, by making the 1st guiding slot part 170S opening significantly, also can make boss portion 610 embed smoothly with respect to boss intercalation permission portion 38, and, even if the width of the 2nd chimeric slot part 160L is larger, by suppressing the A/F of the 2nd guiding slot part 170L, it is excessive that chimeric member 150 does not unexpectedly become, therefore, can in the week of boss intercalation permission portion 38 upwards chimeric member 150 being guaranteed to size required in function, form compactly chimeric member 150.
Specifically,, as shown in Figure 14 (a), suppose to specify situation as follows: the A/F W that is directed away oral area 1710S that makes the 1st guiding slot part 1700S
1710Swith respect to the chimeric width W of the 1st chimeric slot part 1600S

1710S/ W
1600Sbe formed as the A/F W that is directed away oral area 171L with the 2nd above-mentioned guiding slot part 170L
171Lwith respect to the chimeric width W of the 2nd chimeric slot part 160L
160Lamplification degree W
171L/ W
160Lmultiplying power that (Fig. 9 (b)) is identical, for example 1.8 times.
In this case, the 1st guiding slot part 1710S becomes the corresponding narrower A/F W of width of width of the 1st chimeric slot part 1600S narrower with being formed as width
1710S(with reference to Figure 14 (a)).
Therefore, in the time embedding boss portion 610 with respect to boss intercalation permission portion 38, conventionally, the visual field of the inside of boss intercalation permission portion 38 is covered by boss portion 610, therefore, even form the 1st guiding slot part 1700S at the 1st chimeric member 150S, also be difficult to make the 1st fitting projection 615S of boss portion 610 upwards relatively as one man fitting projection 615 to be embedded in to the 1st guiding slot part 170S with the 1st guiding slot part 1700S of boss intercalation permission portion 38 in week, thereby boss portion 610 cannot be embedded smoothly with respect to boss intercalation permission portion 38.
On the other hand, as shown in Fig. 9 (a), for the 1st guiding slot part 170S of present embodiment, although the chimeric width W of the 1st chimeric slot part 160S
160Snarrower, still, the 1st guiding slot part 170S of present embodiment be formed as having wider width ground opening to the A/F W of the 2nd guiding slot part 170L
171Lthe A/F W of ((b) reference of Fig. 9) equal extent
171S.
,, in the 2nd guiding slot part 170L, the A/F W of oral area 171L will be directed away
171Lwith respect to the width W of the end of downstream side 173L of chimeric direction D
173Lamplification degree W
171L/ W
173Lbe set as about 1.8 times (with reference to Fig. 9 (b)), on the other hand, in the 1st guiding slot part 170S, will be directed away the A/F W of oral area 171S
171Swith respect to the width W of the end of downstream side 173S of chimeric direction D
173Samplification degree W
171S/ W
173Sbe set as about 4.2 times (with reference to Fig. 9 (a)), the 1st guiding slot part 170S is formed as: compared with the 2nd guiding slot part 170L, the A/F that is directed away oral area 171 becomes large with respect to the amplification degree of the width of the end of downstream side of chimeric direction D.
Thereby, in the time embedding boss portion 610 with respect to boss intercalation permission portion 38, even if the visual field in boss intercalation permission portion 38 is covered and cannot embed in situation by Visual Confirmation by boss portion 610, also easily make the 1st fitting projection 615S of boss portion 610 upwards relatively consistent with the 1st guiding slot part 170S of boss intercalation permission portion 38 in week, thereby the 1st fitting projection 615 can be embedded in smoothly to the 1st guiding slot part 170S.
And, as mentioned above, suppose the A/F W that is directed away oral area 1710L of the guiding of the 2nd shown in Figure 14 (b) slot part 1700L
1710Lwith respect to the chimeric width W of the 2nd chimeric slot part 1600L
160Lamplification degree W
1710L/ W
1600Lbe set as the A/F W that is directed away oral area 171S with the guiding of the 1st shown in Fig. 9 (a) slot part 170S
171Swith respect to the chimeric width W of the 1st chimeric slot part 160S
160Samplification degree W
171S/ W
160Sidentical multiplying power, for example 4.2 times, in this case, the 2nd guiding slot part 1700L becomes the A/F W of wider width with the width corresponding with the width of the 2nd chimeric slot part 1600L that is formed as wider width
1710L(with reference to Figure 14 (b)).
So, week of boss intercalation permission portion 38 upwards, the shared ratio of the 2nd guiding slot part 1700L becomes excessive, therefore, for example can produce such problem: be difficult to guarantee the space that upwards arranges rotor inner circumferential side fastened component 139 other structures such as grade week in boss intercalation permission portion 38, described rotor inner circumferential side fastened component 139 is for being integrated the concave bottom portion 35 and interior week cylinder portion 33 engagings that form rotor 31.
On the other hand, as shown in the (a) and (b) of Fig. 9, for the 2nd guiding slot part 170L, the chimeric width W of the 2nd chimeric slot part 160L
160Lwider, still, the 2nd guiding slot part 170L be formed as having with the A/F W of the 1st guiding slot part 170S
171Sthe A/F W that equal degree retains
171L.
,, in the 1st guiding slot part 170S, the A/F W of oral area 171S will be directed away

173Samplification degree W
171S/ W
173Sbe set as about 4.2 times (with reference to Fig. 9 (a)), on the other hand, in the 2nd guiding slot part 170L, will be directed away the A/F W of oral area 171L
171Lwith respect to the width W of the end of downstream side 173L of chimeric direction D
173Lamplification degree W
171L/ W
173Lbe set as about 1.8 times (with reference to Fig. 9 (b)), the 2nd guiding slot part 170L is formed as: compared with the 1st guiding slot part 170S, the A/F that is directed away oral area 171 diminishes with respect to the amplification degree of the width of the end of downstream side of chimeric direction D.
Thereby, about the 2nd guiding slot part 170L, by boss portion 610 in boss intercalation permission portion 38 when intercalation, can make the 2nd fitting projection 615L of boss portion 610 embed smoothly, and, the 2nd guiding slot part 170L week of boss intercalation permission portion 38 upwards shared ratio do not become excessive.
Therefore, for example can be in the space for arranging other structures of fastened component 139 grades in rotor inner circumferential side except a pair of chimeric member 150 of upwards guaranteeing in week of boss intercalation permission portion 38.
