Next, the sub-housing 60 is attached to the receptacle terminal 20 serving as the inner connection portion of the three terminals 10 integrally provided on the case main body 31 in the manner described above. Next, the cover portion 50 is covered up to the lower surface opening of the case main body 31 . The locking frame 51 rides on the locking support portion 38 to be elastically displaced and pushed up from below. When the upper edge of the cover portion 50 abuts against the lower edge of the housing body 31, the locking frame 51 returns to its original shape and is embedded in the locking protrusion. 38, so that the cover part 50 is integrally combined to form the housing 30 as shown in FIG. 5 .

At this time, as shown in FIG. 5 , each sub-housing 60 is fitted with the front side rib 68 and the fitting groove 46A, and the front end portion is fitted with a predetermined clearance in the radial direction on the front surface side of the case 30 .

The sealing of the through hole 3 is realized by elastically compressing the surface seal member 36 together and pressing it into the edge of the through hole 3 .

After the terminal board T is attached in this way, the outer connection portion 14 of each terminal 10 is exposed to the upper surface side (outer side) of the case upper wall 2 in a state arranged on the upper surface of the case 30 (base block 40 ). state. On the other hand, the receptacle terminal 20 serving as an inner connection portion of the terminal 10 is housed in a sub-case 60 supported so as to be movable in the radial direction relative to the case 30 .

Next, a procedure for connecting the conductive members of the three poles of the three-phase AC motor and the conductive members of the three poles of the inverter to each other using the terminal board T will be described.

First, the inner conductive member (enameled wire) of the three poles on the motor side is connected to the inner connection portion of the corresponding terminal 10. The terminal insertion opening 65 of the sub-housing 60 attached to the lower end portion of the housing 30 is inserted into the socket terminal 20 located on the inner side.

At this time, even if the core of the round plug terminal p is misaligned with respect to the receptacle terminal 20 , the round plug terminal p is centered and inserted along with the guide portion 66 .

Moreover, there is a deviation in the arrangement position of each round plug terminal p, especially in the case of a large core misalignment, along with the insertion of the round plug terminal p along the guide portion 66, the strip-shaped piece 12 of the terminal 10 is slightly deformed and the sub-housing 60 Move radially to achieve centering.

Then, the round plug terminal p expands and displaces the elastic contact piece 23 of the grid terminal part 21 and is pressed in. When the pressing is stopped, the elastic contact piece 23 returns to the direction of shrinking diameter, so that the round plug terminal p and the socket The terminals 20 are elastically fitted and in contact with each other so that the inner conductive members (enameled wires) of the three poles on the motor side are connected to the inner connection portions (socket terminals 20 ) of the corresponding terminals 10 .

Then, the motor side cases are assembled adjacently so as to cover the front opening of the transmission case 1 .

Next, the three-pole outer conductive members (bus bars) on the inverter side are connected to the outer connection portions 14 of the corresponding terminals 10 . In addition, although not shown in the figure, each bus bar overlaps with the outer connection part 14 arranged side by side on the upper surface of the housing 30, so that the bolts pass through the insertion holes of the bus bars and the insertion holes 15 of the outer connection part 14, and are locked. The nut 42 housed in the storage chamber 43 is screwed and fastened, and the outer conductive member (bus bar) of the three poles on the inverter side is connected to the outer connection portion 14 of the corresponding terminal 10 .

Then, the inverter-side case is assembled on the upper surface of the transmission case 1 and the motor-side case integrated as described above.

Through the above, the conductive members provided on the three poles of the three-phase AC motor and the conductive members provided on the three poles of the inverter are electrically connected to each other through the terminal plate T, and a terminal in the form of directly connecting the motor and the inverter is constructed. connection structure.

In the present embodiment, in the structure in which the portion of the inner conductive member on the motor side is connected to the inner connection portion of the terminal 10 mounted on the terminal board T, the round plug terminal p is provided on the inner conductive member, and the socket terminal is used as the socket terminal. 20 constitutes an inner connection portion of the terminal 10 . Therefore, when connecting the inner conductive member to the inner end connection portion of the terminal 10 , it is realized by fitting the round plug terminal p with the mating receptacle terminal 20 .

Compared with, for example, screw fastening, it is only necessary to fit the round plug terminal p to the receptacle terminal 20 , so the connection work itself is simplified. Furthermore, since the working space for screw fastening can be eliminated, space saving can be achieved, and for example, a motor case can be downsized.

Moreover, in this embodiment, the receptacle terminal 20 of each terminal 10 is respectively accommodated in the sub-housing 60, and on the other hand, each sub-housing 60 is installed in a so-called floating structure so that it can move in the radial direction. housing 30 . For example, when there is a deviation in the arrangement position of each internal conductive member, that is, each plug terminal p, that is, when there is a large core misalignment, etc., it is possible to make the sub-housing 60 play and make each plug terminal p and receptacle terminal 20 be positioned correctly with respect to each other. Heart chimerism.

In particular, the rigidity of the inner conductive member provided with the round plug terminal p is improved, which is effective when there is a limit to the amount of deflection of the inner conductive member itself.

<Embodiment 2>

The terminal 80 has a structure in which a flexible conductor 81 as an easily bendable portion is connected to the hanging end of the bus bar 11 bent and formed in an L-shape. The flexible conductor 81 has a structure in which a braided wire is bent into a substantially S-shape. On the other hand, in the receptacle terminal 20A serving as the inner connection portion, a low connecting piece 24 is formed standing up from the base portion 22 of the grid terminal portion 21 .

In detail, the L-shaped bus bar 11 constituting the terminal 80 is formed reversely to the front and rear of Embodiment 1. On this basis, the upper end of the flexible conductor 81 is in contact with the rear surface of the lower end of the bus bar 11, and the flexible conductor 81 contacts the rear surface of the lower end of the bus bar 11, and the flexible conductor 81 The lower end of the conductor 81 abuts and is fixed by spot welding or the like to the front surface of the upper end of the connection piece 24 standing from the base 22 of the grid terminal 21 . Therefore, in the terminal 80 according to Embodiment 3, the bending direction of the outer connection portion 14 is in the opposite direction to the front and back of the receptacle terminal 20A.

In addition, in order to secure a space for accommodating the substantially S-shaped flexible conductor 81 in the case 30 , there is a configuration in which the outer connection portion of each terminal 10 is arranged in a rearward posture on the upper surface of the case 30 (pedestal block 40 ). , however functionally indistinguishable from the case of the forward-facing posture.

In this Embodiment 3, the sub-housing 60 can move while deforming the flexible conductor 81 in the terminal 80, and similarly can exhibit a floating function more reliably.

Furthermore, when the internal and external conductive members are connected via the terminal board T2 (terminal 80), the flexible conductor 81 provided in the terminal 80 functions as a vibration absorbing part, and when the inner conductive member or the outer conductive member acts as a vibration , the vibration is absorbed by the flexible conductor 81, thereby suppressing the vibration from spreading to the opposite conductive member side.
