　前記第二端部は、前記第二ハウジングの先端に近い端部である。 (1) The connector unit according to the embodiment of the present disclosure includes:
a first connector having a first housing;
a second connector having a second housing;
an elastic member disposed between the outer peripheral surface of the first housing and the inner peripheral surface of the second housing in a state where the first connector and the second connector are fitted together;
The elastic member is
a main body having a cylindrical shape;
comprising a plurality of first protrusions and one or more second protrusions provided on the outer peripheral surface of the main body,
The plurality of first protrusions are provided at intervals from each other around the axis of the main body in a region close to the first end of the main body,
Each of the plurality of first protrusions extends non-orthogonally to the axis of the main body,
The one or more second protrusions are provided continuously around the axis of the main body in a region closer to the second end of the main body than each of the plurality of first protrusions. Ori,
The first end is an end near the tip of the first housing,

　上記（１）のコネクタユニットは、複数の第一突条部を備える弾性部材によって、互いに嵌め合わされた第一コネクタと第二コネクタとの間のがたつきを簡易かつ十分に抑制できる。各第一突条部は、本体部の軸に非直交に交差するように延びている。そのため、各第一突条部は、本体部の軸に沿って延びた突条部に比較して、第二ハウジングの内周面との接触面積を大きく確保できる。第一突条部と第二ハウジングの内周面との接触面積が大きいほど、弾性部材によって第一ハウジングと第二ハウジングとの間のがたつきが良好に抑制される。つまり、第一コネクタの振動が第二コネクタに伝わり難く、かつ第二コネクタの振動が第一コネクタに伝わり難い。その結果、第一コネクタの端子と第二コネクタの端子との接続箇所が振動によって摩耗することが抑制される。第一突条部と第二ハウジングの内周面との接触面積を大きく確保することでがたつきが抑制されるため、第一突条部及び第二突条部を含む弾性部材を単一の材料で構成することができ、弾性部材の成形が容易である。 The connector unit (1) above can easily and sufficiently suppress rattling between the first connector and the second connector that are fitted together by the elastic member including the plurality of first protrusions. Each first protrusion extends non-orthogonally to the axis of the main body. Therefore, each of the first protrusions can secure a larger contact area with the inner circumferential surface of the second housing than the protrusions extending along the axis of the main body. The larger the contact area between the first protrusion and the inner circumferential surface of the second housing, the better the elastic member suppresses rattling between the first housing and the second housing. That is, the vibration of the first connector is difficult to be transmitted to the second connector, and the vibration of the second connector is difficult to be transmitted to the first connector. As a result, wear of the connection portion between the terminal of the first connector and the terminal of the second connector due to vibration is suppressed. By ensuring a large contact area between the first protrusion and the inner circumferential surface of the second housing, rattling is suppressed, so the elastic member including the first protrusion and the second protrusion is integrated into a single piece. The elastic member can be easily molded.
　第一ハウジングの先端領域は寸法管理が難しい。本体部の第一端部に近い領域に第一突条部が設けられていることで、第一ハウジングの外周面と第二ハウジングの内周面との間の寸法公差を第一突条部で吸収することができる。そのため、本体部の第一端部に近い領域に第一突条部が設けられていることで、第一ハウジングと第二ハウジングとの間のがたつきを抑制する効果が高い。 It is difficult to control the dimensions of the tip area of the first housing. By providing the first protrusion in the area near the first end of the main body, the dimensional tolerance between the outer circumferential surface of the first housing and the inner circumferential surface of the second housing can be reduced by the first protrusion. can be absorbed. Therefore, by providing the first protruding portion in the region close to the first end of the main body portion, it is highly effective in suppressing rattling between the first housing and the second housing.
　上記（１）のコネクタユニットでは、第一突条部よりも本体部の第二端部に近い領域に第二突条部が設けられていることで、第一ハウジングと第二ハウジングとの間の止水の効果が高い。 In the connector unit of (1) above, the second protrusion is provided in a region closer to the second end of the main body than the first protrusion, thereby creating a gap between the first housing and the second housing. Highly effective at stopping water.
　（２）上記（１）のコネクタユニットにおいて、前記複数の第一突条部の各々における前記本体部の軸に対する傾斜角度は、５°以上４５°以下であってもよい。 (2) In the connector unit of (1) above, the angle of inclination of each of the plurality of first protrusions with respect to the axis of the main body portion may be 5° or more and 45° or less.
　上記傾斜角度が５°以上であると、第一突条部と第二ハウジングの内周面との接触面積が大きく確保され易く、第一ハウジングと第二ハウジングとの間のがたつきを抑制する効果がより高い。上記傾斜角度が５°以上であると、第一ハウジングと第二ハウジングとの嵌め合いの際に第一突条部にかかる力が弾性部材の軸周りに分散され易く、第一ハウジングと第二ハウジングとを嵌め合わせ易い。上記傾斜角度が４５°以下であると、第一突条部にかかる力の軸周りへの分散と、第二ハウジングの軸に沿った方向のがたつきの抑制とを両立でき、第二コネクタの軸に沿った方向の振動による動きを抑制し易い。 When the above-mentioned inclination angle is 5 degrees or more, a large contact area between the first protrusion and the inner circumferential surface of the second housing is easily ensured, and rattling between the first housing and the second housing is suppressed. is more effective. When the above-mentioned inclination angle is 5 degrees or more, the force applied to the first protrusion portion when the first housing and the second housing are fitted together is likely to be dispersed around the axis of the elastic member, and the first housing and the second Easy to fit with the housing. When the above-mentioned inclination angle is 45° or less, it is possible to balance the dispersion of the force applied to the first protrusion around the axis and the suppression of rattling in the direction along the axis of the second housing, and the second connector It is easy to suppress movement due to vibration in the direction along the axis.
　（３）上記（１）又は上記（２）のコネクタユニットにおいて、前記一つ以上の第二突条部は、前記本体部の軸に沿った方向に間隔をあけて複数設けられていてもよい。 (3) In the connector unit of (1) or (2) above, the one or more second protrusions may be provided in plurality at intervals in the direction along the axis of the main body. .
　複数の第二突条部が設けられていると、第一ハウジングと第二ハウジングとの間の止水性が高い。 When a plurality of second protrusions are provided, water-tightness between the first housing and the second housing is high.
　（４）上記（１）から上記（３）のいずれかのコネクタユニットにおいて、前記複数の第一突条部の数は、前記一つ以上の第二突条部の数以上であってもよい。 (4) In the connector unit according to any one of (1) to (3) above, the number of the plurality of first protrusions may be greater than or equal to the number of the one or more second protrusions. .
　第一突条部の数が多いほど、第一突条部と第二ハウジングの内周面との接触面積が大きく確保され易く、第一ハウジングと第二ハウジングとの間のがたつきを抑制する効果がより高い。 The larger the number of first protrusions, the larger the contact area between the first protrusions and the inner circumferential surface of the second housing, which helps to suppress rattling between the first and second housings. is more effective.
　（５）上記（１）から上記（４）のいずれかのコネクタユニットにおいて、前記複数の第一突条部の各々と前記一つ以上の第二突条部とは、前記本体部の軸に沿った方向に間隔をあけて配置されていてもよい。 (5) In the connector unit according to any one of (1) to (4) above, each of the plurality of first protrusions and the one or more second protrusions are arranged on the axis of the main body. They may be arranged at intervals along the direction.
　第一突条部と第二突条部とが間隔をあけて配置されていると、第一突条部と第二突条部が互いに影響を及ぼし難い。その結果、第一突条部によるがたつき抑制の機能と第二突条部による止水の機能とが互いに影響することなく発揮される。 When the first protrusion portion and the second protrusion portion are spaced apart, the first protrusion portion and the second protrusion portion are difficult to influence each other. As a result, the rattling suppressing function of the first protrusion and the water stopping function of the second protrusion are exerted without affecting each other.
　（６）上記（１）から上記（５）のいずれかのコネクタユニットにおいて、前記複数の第一突条部は、互いに交差するように延びる第三突条部および第四突条部を含んでもよい。 (6) In the connector unit according to any one of (1) to (5) above, the plurality of first protrusions may include a third protrusion and a fourth protrusion that extend to intersect with each other. good.
　第一突条部に第三突条部及び第四突条部が含まれると、第一突条部と第二ハウジングの内周面との接触面積が大きく確保され易い。第三突条部と第四突条部とが互いに交差する、つまり第三突条部と第四突条部とが互いに異なる方向に延びていると、第一ハウジングと第二ハウジングとの間のがたつきが抑制され易い。 When the first protrusion includes the third protrusion and the fourth protrusion, a large contact area between the first protrusion and the inner circumferential surface of the second housing is easily ensured. If the third protrusion and the fourth protrusion cross each other, that is, the third protrusion and the fourth protrusion extend in different directions, the space between the first housing and the second housing Shake is easily suppressed.
　（７）本開示の実施形態に係る弾性部材は、
　第一コネクタに備わる第一ハウジングの外周面と第二コネクタに備わる第二ハウジングの内周面との間に配置される弾性部材であって、
　筒状の形状を有する本体部と、
　前記本体部の外周面に設けられた複数の第一突条部および一つ以上の第二突条部と、を備え、
　前記複数の第一突条部は、前記本体部の第一端部に近い領域において、前記本体部の軸周りに互いに間隔をあけて設けられており、
　前記複数の第一突条部の各々は、前記本体部の軸に非直交に交差するように延びており、
　前記一つ以上の第二突条部は、前記複数の第一突条部の各々よりも前記本体部の第二端部に近い領域において、前記本体部の軸周りに連続して設けられている。 (7) The elastic member according to the embodiment of the present disclosure is
An elastic member disposed between an outer circumferential surface of a first housing provided in the first connector and an inner circumferential surface of a second housing provided in the second connector,
a main body having a cylindrical shape;
comprising a plurality of first protrusions and one or more second protrusions provided on the outer peripheral surface of the main body,
The plurality of first protrusions are provided at intervals from each other around the axis of the main body in a region close to the first end of the main body,
Each of the plurality of first protrusions extends non-orthogonally to the axis of the main body,
The one or more second protrusions are provided continuously around the axis of the main body in a region closer to the second end of the main body than each of the plurality of first protrusions. There is.
　上記（７）の弾性部材は、複数の第一突条部を備えることで、第一コネクタと第二コネクタとの間のがたつきを簡易かつ十分に抑制できる。各第一突条部は、本体部の軸に非直交に交差するように延びている。そのため、各第一突条部は、本体部の軸に沿って延びた突条部に比較して、第二ハウジングの内周面との接触面積を大きく確保できる。第一突条部と第二ハウジングの内周面との接触面積が大きいほど、弾性部材によって第一ハウジングと第二ハウジングとの間のがたつきが良好に抑制される。つまり、第一コネクタの振動が第二コネクタに伝わり難く、かつ第二コネクタの振動が第一コネクタに伝わり難い。その結果、第一コネクタの端子と第二コネクタの端子との接続箇所が振動によって摩耗することが抑制される。第一突条部と第二ハウジングの内周面との接触面積を大きく確保することでがたつきが抑制されるため、第一突条部及び第二突条部を含む弾性部材を単一の材料で構成することができ、弾性部材の成形が容易である。 By including the plurality of first protrusions, the elastic member (7) above can easily and sufficiently suppress rattling between the first connector and the second connector. Each first protrusion extends non-orthogonally to the axis of the main body. Therefore, each of the first protrusions can secure a larger contact area with the inner circumferential surface of the second housing than the protrusions extending along the axis of the main body. The larger the contact area between the first protrusion and the inner circumferential surface of the second housing, the better the elastic member suppresses rattling between the first housing and the second housing. That is, the vibration of the first connector is difficult to be transmitted to the second connector, and the vibration of the second connector is difficult to be transmitted to the first connector. As a result, wear of the connection portion between the terminal of the first connector and the terminal of the second connector due to vibration is suppressed. By ensuring a large contact area between the first protrusion and the inner circumferential surface of the second housing, rattling is suppressed, so the elastic member including the first protrusion and the second protrusion is integrated into a single piece. The elastic member can be easily molded.

The cross-sectional shape of the main body portion 30 in this example is a substantially rectangular shape that is elongated from side to side. The length of the main body portion 30 along the axis is, for example, the same as the length of the first cylindrical portion 111 along the axis. The length of the main body portion 30 along the axis may be shorter than the length of the first cylindrical portion 111 along the axis. The circumferential length of the inner circumferential surface of the main body portion 30 is slightly smaller than the circumferential length of the outer circumferential surface of the first cylindrical portion 111 . When the elastic member 3 is attached to the outer periphery of the first cylindrical portion 111, the main body portion 30 comes into close contact with the outer periphery of the first cylindrical portion 111.
　本体部３０は、中央領域４０、第一領域４１、及び第二領域４２の三つの領域に分けられる。中央領域４０は、本体部３０の軸に沿った中央に位置する領域である。第一領域４１は、本体部３０の第一端部３１に近い領域である。第二領域４２は、本体部３０の第二端部３２に近い領域である。第一端部３１は、弾性部材３の内側にある第一筒部１１１の先端に近い端部である。第二端部３２は、弾性部材３の外側にある第二ハウジング２１の先端に近い端部である。第一端部３１は、弾性部材３の外側にある第二ハウジング２１の基端に近い端部でもある。第二端部３２は、弾性部材３の内側にある第一筒部１１１の基端に近い端部でもある。 The main body portion 30 is divided into three regions: a central region 40, a first region 41, and a second region 42.

　〔第一突条部〕
　複数の第一突条部５１は、第一ハウジング１１と第二ハウジング２１との間のがたつきを抑制する機能を有する。複数の第一突条部５１は、図６から図９に示すように、本体部３０の第一領域４１に設けられている。図４及び図５に示すように、弾性部材３が第一筒部１１１と第二ハウジング２１との間に配置された状態では、複数の第一突条部５１は第一筒部１１１の先端の一部に局所的に配置されている。第一筒部１１１の先端領域は寸法管理が難しい。第一筒部１１１の先端領域に複数の第一突条部５１が設けられていると、第一筒部１１１と第二ハウジング２１との間の寸法公差を各第一突条部５１で吸収することができる。そのため、第一筒部１１１の先端領域に複数の第一突条部５１が設けられていると、第一ハウジング１１と第二ハウジング２１との間のがたつきを抑制する効果が高い。 [First protrusion section]
The plurality of first protrusions 51 have a function of suppressing rattling between the first housing 11 and the second housing 21. The plurality of first protrusions 51 are provided in the first region 41 of the main body 30, as shown in FIGS. 6 to 9. As shown in FIGS. 4 and 5, when the elastic member 3 is disposed between the first cylindrical portion 111 and the second housing 21, the plurality of first protrusions 51 are at the tip of the first cylindrical portion 111. are located locally in some parts of the Dimensional control of the tip region of the first cylindrical portion 111 is difficult. When a plurality of first protrusions 51 are provided in the tip region of the first cylindrical part 111, the dimensional tolerance between the first cylindrical part 111 and the second housing 21 is absorbed by each of the first protrusions 51. can do. Therefore, when the plurality of first protrusions 51 are provided in the distal end region of the first cylindrical portion 111, the effect of suppressing rattling between the first housing 11 and the second housing 21 is high.
　複数の第一突条部５１は、図６に示すように、本体部３０の軸周りに互いに間隔をあけて設けられている。複数の第一突条部５１は、等間隔に並んでいるとよい。隣り合う第一突条部５１間の間隔は、各第一突条部５１の幅Ｗ１（図７）と同等以下であるとよい。本例では、上記間隔は、幅Ｗ１よりも若干小さい。 As shown in FIG. 6, the plurality of first protrusions 51 are provided at intervals around the axis of the main body 30. The plurality of first protrusions 51 are preferably arranged at equal intervals. The interval between adjacent first protrusions 51 is preferably equal to or less than the width W1 (FIG. 7) of each first protrusion 51. In this example, the interval is slightly smaller than the width W1.
　各第一突条部５１は、本体部３０の軸に非直交に交差するように延びている。本体部３０の軸に非直交とは、本体部３０の軸に対する角度が０°超９０°未満であることをいう。各第一突条部５１は、本体部３０の軸に沿って延びた突条部に比較して、第二ハウジング２１の内周面との接触面積を大きく確保できる。第一突条部５１と第二ハウジング２１の内周面との接触面積が大きいほど、弾性部材３によって第一ハウジング１１と第二ハウジング２１との間のがたつきが良好に抑制される。また、各第一突条部５１は、本体部３０の軸に沿って延びた突条部に比較して、第一ハウジング１１と第二ハウジング２１との嵌め合いが行い易い。本体部３０の軸に沿って延びた突条部だと、第一ハウジング１１と第二ハウジング２１とが嵌め合わされるとき、突条部には本体部３０の軸に沿った力がかかり、第一ハウジング１１と第二ハウジング２１との嵌め合いが難しい。第一突条部５１だと、第一ハウジング１１と第二ハウジング２１との嵌め合いの際に第一突条部５１にかかる力が本体部３０の軸周りに分散され易く、第一ハウジング１１と第二ハウジング２１との嵌め合いが行い易い。 Each first protrusion 51 extends non-orthogonally to the axis of the main body 30. Non-orthogonal to the axis of the main body 30 means that the angle with the axis of the main body 30 is greater than 0° and less than 90°. Each of the first protrusions 51 can secure a larger contact area with the inner circumferential surface of the second housing 21 than the protrusions extending along the axis of the main body 30 . The larger the contact area between the first protrusion portion 51 and the inner circumferential surface of the second housing 21, the better the vibration between the first housing 11 and the second housing 21 is suppressed by the elastic member 3. Moreover, each first protruding portion 51 allows the first housing 11 and the second housing 21 to fit together more easily than the protruding portion extending along the axis of the main body portion 30 . If the protrusion extends along the axis of the main body 30, when the first housing 11 and the second housing 21 are fitted together, a force is applied to the protrusion along the axis of the main body 30, and the second It is difficult to fit the first housing 11 and the second housing 21 together. With the first protruding portion 51, the force applied to the first protruding portion 51 when the first housing 11 and the second housing 21 are fitted together is easily dispersed around the axis of the main body portion 30. The fitting between the second housing 21 and the second housing 21 is easy.
　各第一突条部５１における本体部３０の軸に対する傾斜角度Ａ１（図７）は、例えば５°以上４５°以下である。傾斜角度Ａ１が５°以上であると、第一突条部５１と第二ハウジング２１の内周面との接触面積が大きく確保され易く、第一ハウジング１１と第二ハウジング２１との間のがたつきを抑制する効果がより高い。傾斜角度Ａ１が５°以上であると、第一ハウジング１１と第二ハウジング２１との嵌め合いが行い易いという効果もある。上記傾斜角度が４５°以下であると、第一突条部５１にかかる力の軸周りへの分散と、第二ハウジング２１の軸に沿った方向のがたつきの抑制とを両立でき、第二コネクタ２の軸に沿った方向の振動による動きを抑制し易い。傾斜角度Ａ１は、５°以上３０°以下、更に５°以上２０°以下、５°以上１５°以下であってもよい。 The inclination angle A1 (FIG. 7) of each first protruding portion 51 with respect to the axis of the main body portion 30 is, for example, 5° or more and 45° or less. When the inclination angle A1 is 5° or more, a large contact area between the first protruding portion 51 and the inner circumferential surface of the second housing 21 is easily ensured, and the distance between the first housing 11 and the second housing 21 is increased. It is more effective in suppressing heat. When the inclination angle A1 is 5 degrees or more, there is also the effect that the first housing 11 and the second housing 21 can be easily fitted together. When the above-mentioned inclination angle is 45° or less, it is possible to balance the dispersion of the force applied to the first protrusion portion 51 around the axis and the suppression of wobbling in the direction along the axis of the second housing 21, and the second Movement due to vibration in the direction along the axis of the connector 2 can be easily suppressed. The inclination angle A1 may be 5° or more and 30° or less, further 5° or more and 20° or less, or 5° or more and 15° or less.
　複数の第一突条部５１の数は、各第一突条部５１の幅及び隣り合う第一突条部５１間の間隔にもよるが、多いほどよい。第一突条部５１の数が多いほど、第一突条部５１と第二ハウジング２１の内周面との接触面積が大きく確保され易い。第一突条部５１の数が多いほど、本体部３０の軸周りに均一的に第一突条部５１が配置され易い。複数の第一突条部５１の数は、第二突条部５２の数以上であってもよい。 The number of the plurality of first protrusions 51 depends on the width of each first protrusion 51 and the interval between adjacent first protrusions 51, but the larger the number, the better. The larger the number of first protrusions 51, the larger the contact area between the first protrusions 51 and the inner circumferential surface of the second housing 21. The greater the number of the first protrusions 51, the easier it is for the first protrusions 51 to be uniformly arranged around the axis of the main body portion 30. The number of the plurality of first protrusions 51 may be greater than the number of the second protrusions 52.
　各第一突条部５１の幅Ｗ１（図７）は適宜選択できる。各第一突条部５１の幅Ｗ１は、第一突条部５１における本体部３０の軸周りに沿った最大長さである。本例の第一突条部５１は、第一突条部５１の長さに沿って均一な幅Ｗ１を有する。本例の第一突条部５１は、第一突条部５１の高さに沿って均一な幅Ｗ１を有する。第一突条部５１の高さは、第一突条部５１における本体部３０の外周面からの突出長さである。第一突条部５１は、長さに沿って異なる幅Ｗ１を有していてもよい。第一突条部５１は、第一突条部５１の高さに沿って異なる幅Ｗ１を有していてもよい。第一突条部５１の幅Ｗ１は、例えば１ｍｍ以上である。 The width W1 (FIG. 7) of each first protruding portion 51 can be selected as appropriate. The width W1 of each first protruding portion 51 is the maximum length of the first protruding portion 51 along the axis of the main body portion 30 . The first protruding portion 51 of this example has a uniform width W1 along the length of the first protruding portion 51. The first protruding portion 51 of this example has a uniform width W1 along the height of the first protruding portion 51. The height of the first protruding portion 51 is the length of the first protruding portion 51 protruding from the outer circumferential surface of the main body portion 30 . The first protruding portion 51 may have a width W1 that varies along its length. The first protruding portion 51 may have a width W1 that differs along the height of the first protruding portion 51. The width W1 of the first protruding portion 51 is, for example, 1 mm or more.
　各第一突条部５１の高さは、各第一突条部５１の長さの中間部から両端部に向かって低くなるように構成されていてもよい。このような高さであれば、第一コネクタ１と第二コネクタ２との抜き差しが行い易い。 The height of each first protruding portion 51 may be configured to decrease from the middle portion of the length of each first protruding portion 51 toward both ends. With such a height, it is easy to connect and disconnect the first connector 1 and the second connector 2.
　〔第二突条部〕
　第二突条部５２は、第一ハウジング１１と第二ハウジング２１との間の止水の機能を有する。第二突条部５２は、図６から図９に示すように、複数の第一突条部５１よりも第二端部３２の近くに設けられている。本例の第二突条部５２は、本体部３０の中央領域４０に設けられている。図４及び図５に示すように、弾性部材３が第一筒部１１１と第二ハウジング２１との間に配置された状態では、第二突条部５２は各第一突条部５１よりも第一筒部１１１の基端に近い領域の一部に局所的に配置されている。第二突条部５２が各第一突条部５１より第一筒部１１１の基端に近い領域に設けられていると、第一ハウジング１１と第二ハウジング２１との間の止水の効果が高い。 [Second protrusion section]
The second protruding portion 52 has a water stop function between the first housing 11 and the second housing 21. The second protrusion 52 is provided closer to the second end 32 than the plurality of first protrusions 51, as shown in FIGS. 6 to 9. The second protruding portion 52 of this example is provided in the central region 40 of the main body portion 30. As shown in FIGS. 4 and 5, when the elastic member 3 is disposed between the first cylindrical portion 111 and the second housing 21, the second protruding portion 52 is larger than each first protruding portion 51. It is locally arranged in a part of the region near the base end of the first cylindrical part 111. When the second protruding portion 52 is provided in a region closer to the base end of the first cylindrical portion 111 than each first protruding portion 51, water can be stopped between the first housing 11 and the second housing 21. is high.
　第二突条部５２の数は、一つ又は複数である。複数の第二突条部５２が設けられていると、第一ハウジング１１と第二ハウジング２１との間の止水性が高くなる。本例では、本体部３０の軸に沿った方向に間隔をあけて二つの第二突条部５２が設けられている。 The number of second protrusions 52 is one or more.
