図4に示すように、互いに接合されてオイルに浸漬されたメスコネクタ11及びオスコネクタ51は、トランスミッション内で循環されるオイルの流れに沿う方向(図4中矢印A方向)に、互いの接合方向を向けて配置される。
FIG. 4 is a cross-sectional view showing the flow of oil in the connector structure according to the embodiment.
As shown in FIG. 4, the female connector 11 and the male connector 51 joined to each other and immersed in oil are joined to each other in a direction along the flow of oil circulated in the transmission (in the direction of arrow A in FIG. 4). Arranged in a direction.

このように配置された状態では、トランスミッション内を循環するオイルが、メスハウジング12が嵌合されたオスハウジング52の開口部63から内部に流れ込む(図4中矢印B参照)。なお、オスハウジング52内には、ロックアーム18のロック爪17が係止された係合孔55からもオイルが流れ込む。そして、このオスハウジング52の内部に流れ込んだオイルは、オスハウジング52の底壁部61へ向かって流れることで、メス端子31とオス端子71との導通接続箇所Sを通り、底壁部61の孔部65から外部へ流れ出る。   In such a state, the oil circulating in the transmission flows into the inside from the opening 63 of the male housing 52 in which the female housing 12 is fitted (see arrow B in FIG. 4). Note that oil also flows into the male housing 52 from the engagement hole 55 in which the lock claw 17 of the lock arm 18 is locked. The oil that has flowed into the male housing 52 flows toward the bottom wall portion 61 of the male housing 52, and thus passes through the conductive connection point S between the female terminal 31 and the male terminal 71. It flows out from the hole 65 to the outside.

図5は、参考例に係るコネクタ構造におけるオイルの流れを示す断面図である。
図5に示すように、オスハウジング52に孔部65が形成されていないと、トランスミッション内を循環するオイルは、オスハウジング52の開口部63や係合孔55からオスハウジング52内に流れ込み(図5中矢印C参照)、オスハウジング52の嵌合凹部53の奥で滞留する(滞留している箇所は、図5中D部参照)。すると、オスハウジング52内で滞留している高温のオイルによってメス端子31及びオス端子71が損傷するおそれがある。例えば、メス端子31及びオス端子71は、高温のオイルに長時間接触すると、表面に施された錫メッキが剥離するような損傷を受ける。これにより、メス端子31及びオス端子71では、その導通接続箇所Sにおける接続信頼性が低下するおそれがある。
FIG. 5 is a cross-sectional view showing the flow of oil in the connector structure according to the reference example.
As shown in FIG. 5, if the hole 65 is not formed in the male housing 52, the oil circulating in the transmission flows into the male housing 52 from the opening 63 and the engagement hole 55 of the male housing 52 (see FIG. 5). 5 (see arrow C in FIG. 5), and stays behind the fitting recess 53 of the male housing 52 (see the portion D in FIG. 5 for the staying location). Then, the female terminal 31 and the male terminal 71 may be damaged by the high-temperature oil staying in the male housing 52. For example, when the female terminal 31 and the male terminal 71 are in contact with hot oil for a long time, they are damaged such that the tin plating applied to the surface peels off. Thereby, in the female terminal 31 and the male terminal 71, there exists a possibility that the connection reliability in the conduction | electrical_connection connection location S may fall.

これに対して、本実施形態では、メスコネクタ11とオスコネクタ51とを接合させた状態で、オスハウジング52の開口部63と孔部65とを通る流路が形成される。孔部65がメス端子31とオス端子71との導通接続箇所Sよりも開口部63と反対側に設けられているので、流路をオイルが流れることで、メスハウジング12が嵌合されたオスハウジング52内における導通接続箇所S付近でのオイルの滞留が抑制される。これにより、オスハウジング52内に滞留する高温のオイルによって、メス端子31及びオス端子71のメッキが剥離するような影響を抑制し、メス端子31とオス端子71との導通接続箇所Sにおける高い接続信頼性を維持することができる。   On the other hand, in this embodiment, a flow path that passes through the opening 63 and the hole 65 of the male housing 52 is formed in a state where the female connector 11 and the male connector 51 are joined. Since the hole 65 is provided on the opposite side of the opening 63 from the conductive connection point S between the female terminal 31 and the male terminal 71, the male housing 12 is fitted into the male housing 12 when oil flows through the flow path. Oil retention in the vicinity of the conductive connection point S in the housing 52 is suppressed. This suppresses the influence that the plating of the female terminal 31 and the male terminal 71 is peeled off by the high-temperature oil staying in the male housing 52, and the high connection at the conductive connection point S between the female terminal 31 and the male terminal 71. Reliability can be maintained.

特に、開口部63に対向する底壁部61に孔部65を形成したことで、開口部63と孔部65とを通る流路におけるオイルの流れを円滑することができ、オスハウジング52内における導通接続箇所S付近でのオイルの滞留を確実に抑制し、滞留するオイルによるメス端子31及びオス端子71への影響を抑制し、メス端子31とオス端子71との導通接続箇所Sにおける高い接続信頼性を維持することができる。   In particular, by forming the hole 65 in the bottom wall portion 61 that faces the opening 63, the oil flow in the flow path that passes through the opening 63 and the hole 65 can be made smooth, The oil staying in the vicinity of the conductive connection point S is reliably suppressed, the influence of the staying oil on the female terminal 31 and the male terminal 71 is suppressed, and the high connection at the conductive connection point S between the female terminal 31 and the male terminal 71 is achieved. Reliability can be maintained.

また、底壁部61におけるオス端子71の配列に沿って孔部65が形成されているので、開口部63と底壁部61の孔部65とを通る流路がオス端子71の配列に沿って形成される。これにより、開口部63と底壁部61の孔部65とを通る流路をオイルが流れることで、オスハウジング52内における導通接続箇所S付近でのオイルの滞留をオス端子71の配列に沿って確実に抑制し、滞留するオイルによるメス端子31及びオス端子71への影響を抑制し、それぞれのメス端子31とオス端子71との導通接続箇所Sにおける高い接続信頼性を維持することができる。   Further, since the hole 65 is formed along the arrangement of the male terminals 71 in the bottom wall 61, the flow path passing through the opening 63 and the hole 65 of the bottom wall 61 follows the arrangement of the male terminals 71. Formed. As a result, the oil flows along the flow path passing through the opening 63 and the hole 65 of the bottom wall portion 61, so that the oil stays in the vicinity of the conductive connection point S in the male housing 52 along the arrangement of the male terminals 71. It is possible to reliably suppress and suppress the influence on the female terminal 31 and the male terminal 71 due to the staying oil, and to maintain high connection reliability at the conductive connection point S between the female terminal 31 and the male terminal 71. .

しかも、メスコネクタ11及びオスコネクタ51は、互いの接合方向がオイルの流れに沿う方向に配置されているので、開口部63と孔部65とを通る流路へオイルが円滑に流れることとなり、メスハウジング12が嵌合されたオスハウジング52内における導通接続箇所S付近でのオイルの滞留をより確実に抑制することができる。   Moreover, since the female connector 11 and the male connector 51 are arranged in a direction in which the mutual joining direction follows the flow of oil, the oil smoothly flows into the flow path passing through the opening 63 and the hole 65, It is possible to more reliably suppress oil stagnation in the vicinity of the conductive connection point S in the male housing 52 in which the female housing 12 is fitted.

なお、互いに接合させたメスコネクタ11及びオスコネクタ51は、図6に示すように、互いの接合方向が鉛直方向に沿うように配置することが好ましい。このように、互いの接合方向が鉛直方向に沿うように、メスコネクタ11及びオスコネクタ51を配置すれば、開口部63と孔部65とを通る流路や係合孔55と孔部65とを通る流路に対して、熱による対流や重力によってオイルが円滑に流れることとなり(図6中矢印E参照)、メスハウジング12が嵌合されたオスハウジング52内における導通接続箇所S付近でのオイルの滞留をさらに確実に抑制することができる。   In addition, as shown in FIG. 6, it is preferable to arrange | position the female connector 11 and the male connector 51 which were mutually joined so that a mutual joining direction may follow a perpendicular direction. In this way, if the female connector 11 and the male connector 51 are arranged so that the mutual joining direction is along the vertical direction, the flow path passing through the opening 63 and the hole 65 and the engagement hole 55 and the hole 65 Oil flows smoothly by heat convection and gravity (see arrow E in FIG. 6), and in the vicinity of the conductive connection point S in the male housing 52 in which the female housing 12 is fitted. Oil retention can be further reliably suppressed.

なお、上記実施形態では、互いに接合させたメスコネクタ11及びオスコネクタ51に対して、オスハウジング52の開口部63からオイルが流入して孔部65から流出する場合を例示したが、オイルの流れによっては、オスハウジング52の孔部65からオイルが流入して開口部63や係合孔55から流出する場合もある。この場合も、オスハウジング52内をオイルが流れることで、メスハウジング12が嵌合されたオスハウジング52内における導通接続箇所S付近でのオイルの滞留が抑制される。   In the above embodiment, the case where the oil flows into the female connector 11 and the male connector 51 that are joined to each other from the opening 63 of the male housing 52 and flows out of the hole 65 is illustrated. Depending on the case, oil may flow from the hole 65 of the male housing 52 and flow out of the opening 63 or the engagement hole 55. Also in this case, the oil flows in the male housing 52, so that the oil stays in the vicinity of the conductive connection point S in the male housing 52 in which the female housing 12 is fitted is suppressed.

また、上記実施形態では、オスハウジング52の底壁部61に孔部65を形成したが、孔部65は、メス端子31とオス端子71との導通接続箇所Sよりも開口部63と反対側であれば、底壁部61に限らず、オスハウジング52の周壁部62を構成する底面部62a、側面部62bあるいは上面部62cに形成しても良い。この場合も、開口部63と孔部65とを通るオスハウジング52内の流路をオイルが流れることで、メスハウジング12が嵌合されたオスハウジング52内における導通接続箇所S付近でのオイルの滞留が抑制される。   Moreover, in the said embodiment, although the hole 65 was formed in the bottom wall part 61 of the male housing 52, the hole 65 is on the opposite side to the opening part 63 rather than the conduction | electrical_connection connection location S of the female terminal 31 and the male terminal 71. As long as it is not limited to the bottom wall portion 61, it may be formed on the bottom surface portion 62a, the side surface portion 62b, or the top surface portion 62c constituting the peripheral wall portion 62 of the male housing 52. Also in this case, the oil flows in the flow path in the male housing 52 that passes through the opening 63 and the hole 65, so that the oil near the conductive connection point S in the male housing 52 in which the female housing 12 is fitted. Residence is suppressed.
