Specifically, four slits 96 are formed in the peripheral wall 91, whereby the peripheral wall 91 is divided into four equal parts in the circumferential direction into four divided bodies 97. Further, the second terminal 90 has a convex portion 99 that bulges downward on the inner surface of the upper wall 92 .

As shown in FIGS. 1 and 2, the second terminal 90 is assembled into the housing 80 from above. Then, the second terminal 90 is supported by the lower edge of the peripheral wall 91 coming into contact with the support plate 85 of the housing 80 . Further, when the second terminal 90 is assembled to the housing 80, the locking pawl 87 formed on the locking portion 86 of the housing locks the edge of the upper wall 92. As a result, the second connector 70 has the second terminal 90 assembled to the housing 80.

The housing 80 of the second connector 70 is fitted into the fitting hole 73 of the inverter case 71 from inside. In this state, the second connector 70 is fixed to the inverter case 71 by screwing the screw 75 inserted into the insertion hole 83 formed in the fixing piece 82 of the housing 80 into the screw hole formed in the inverter case 71. . In the second connector 70 fixed to the inverter case 71 , a bus bar 93 connected to a second terminal 90 is connected to a bus bar 76 that is wiring for the inverter inside the inverter case 71 .

In the above-mentioned connector structure 10, the inverter with the second connector 70 facing downward is placed and assembled from the upper side of the drive motor with the first connector 20 facing upward. Thereby, the second connector 70 is easily fitted to the first connector 20 due to the weight of the inverter.

Hereinafter, a case in which the second connector 70 is fitted to the first connector 20 will be described in detail.
FIG. 6 is a sectional view along the fitting direction showing a state in which the first connector 20 and the second connector 70 shown in FIG. 2 are being fitted.

To fit the second connector 70 into the first connector 20, the inverter with the second connector 70 facing downward is brought close to the drive motor with the first connector 20 facing upward from above. Then, the fitting protrusion 72 of the inverter case 71 is fitted into the fitting recess 22 of the motor case 21 .

Then, as shown in FIG. 6, the housing 80 of the second connector 70 is fitted into the housing 30 of the first connector 20. At this time, the protruding contact point 95 on the lower edge of the divided body 97 formed on the second terminal 90 of the second connector 70 comes into contact with the protruding part 48 of the protruding part 43 of the first terminal 40 of the first connector 20. be done. As a result, the protruding contact 95 comes into sliding contact with the outer circumferential surface of the overhanging portion 48, and the lower edge of the divided body 97 is elastically deformed so as to be pushed outward in the radial direction.

Thereafter, when the inverter is placed on top of the drive motor and assembled, the fitting protrusion 72 of the inverter case 71 is completely fitted into the fitting recess 22 of the motor case 21, and the housing 30 of the first connector 20 is completely fitted. The housing 80 of the second connector 70 is completely fitted. As a result, the protruding contact point 95 of the divided body 97 moves further forward in the fitting direction than the protruding portion 48 of the bulged portion 43, so that the divided body 97, which has been elastically deformed, is restored to its original state.

Then, as shown in FIG. 1, the protruding contact 95 of the restored divided body 97 presses the annular contact 50 held by the holding part 46 of the engaging part 41 of the first terminal 40 from the outer circumferential side. As a result, the annular contact 50 is held between the engaging portion 41 of the first terminal 40 and the protrusion contact 95. Therefore, the plurality of contacts 52 of the annular contact 50 are evenly contacted with the protrusion contact 95, and the first terminal 40 of the first connector 20 and the second terminal 90 of the second connector 70 are connected via the annular contact 50. Conducted. Thereby, the bus bar 26 on the drive motor side and the bus bar 76 on the inverter side are electrically connected.

Further, in this state, the projecting portion 48 of the bulging portion 43 formed on the first terminal 40 of the first connector 20 comes into contact with the inner peripheral surface of each divided body 97 of the second terminal 90 of the second connector 70. . Furthermore, the convex portion 49 of the bulge 43 formed on the first terminal 40 of the first connector 20 comes into contact with the convex portion 99 of the upper wall 92 of the second terminal 90 of the second connector 70 .

To release the fitted state between the first connector 20 and the second connector 70, the inverter assembled to the drive motor is removed and lifted upward relative to the drive motor. Then, as shown in FIG. 2, the housing 80 of the second connector 70 is pulled out from the housing 30 of the first connector 20, and the first Terminal 40 is pulled out. As a result, the first terminal 40 and the second terminal 90 are separated, and the electrical connection between the bus bar 26 on the drive motor side and the bus bar 76 on the inverter side is released.

As described above, according to the connector structure 10 according to the first embodiment, the first terminal 40 of the first connector 20 has a plurality of contacts 52 provided on the outer circumferential side at intervals in the circumferential direction. The second terminal 90 of the second connector 70 has a cylindrical shape in which the contact 52 of the annular contact 50 comes into contact with the inner peripheral surface when the first terminal 40 is fitted. is formed. As a result, compared to a connector structure that has a male terminal that extends along the mating direction and a female terminal into which the male terminal is inserted and removed, it is possible to reduce the bulkiness of the dimensions in the mating direction and save space. A sufficient contact area between the two can be secured.

Moreover, the annular contactor 50 is formed by forming a wire made of a conductive metal material into a spiral shape and then connecting both ends to form a ring shape, so that the part protruding toward the outer periphery of the spirally formed wire serves as a contact point. It is said to be 52. Therefore, by forming a wire made of a conductive metal material into a spiral shape and then connecting both ends to form an annular shape, the annular contactor 50 has a plurality of contacts 52 provided on the outer circumferential side at intervals in the circumferential direction. can be easily obtained.

Furthermore, by fitting the first connector 20 and the second connector 70 together, the protrusion contact 95 of the second terminal 90 that extends beyond the protrusion 48 of the first terminal 40 is locked to the protrusion 48 . Thereby, the connection state between the first terminal 40 and the second terminal 90 can be maintained, and rattling in the direction perpendicular to the fitting direction can be suppressed.

Further, when the first connector 20 and the second connector 70 are fitted together, the convex portions 49 and 99 of the first terminal 40 and the second terminal 90 are brought into contact with each other. Thereby, rattling in the fitting direction can be suppressed.

In the connector structure 10 of the first embodiment, the first connector 20 and the second connector 70 are fitted together by assembling the inverter case 71 to the motor case 21, so there is no need for wiring such as a wire harness. Can be done. Furthermore, since bulkiness in the fitting direction is suppressed, the overall size of the vehicle drive device including the motor case 21 and the inverter case 71 can be reduced.
