  Hereinafter, a connector-integrated bus bar structure according to an embodiment of the present invention will be described with reference to the drawings.

  1 to 20 show a connector-integrated bus bar structure according to an embodiment of the present invention.

  First, in terms of the overall configuration, in the connector-integrated bus bar structure of this embodiment, as shown in FIG. 1, an annular bus bar 1 is a long plate bus bar base material as a single plate bus bar base material. 2 is mainly configured by having a bus bar body 2a that is curved in an annular shape and approximates a substantially circular shape in plan view (viewed in the Z direction in FIG. 1).

  The bus bar main body 2a has a certain width direction dimension W, and the connector portion 3 constituted by a metal flat plate member which is the same member of the same material is formed from a part of the outer surface. It is formed so as to project integrally toward the outside.

  This connector part 3 bends the both ends 2b and 2c which are faced | matched by curvature among the said long plate-shaped bus-bar base materials 2 toward the outer side of radial direction D, respectively, and inner surface 2d and 2e are opposed. , Exhibiting a superimposed shape.

  In addition, each of the end portions 2c of the connector portion 3 is bent inwardly to have a substantially C-shaped cross section, thereby being locked to the outer peripheral edge of the other end portion 2b. A pair of locking pieces 2f, 2f covering the periphery of the end 2b are integrally formed.

  Then, the mating terminal 5 provided at the tip of the conductor 4 as the electrical wiring for conducting electrical conduction is inserted from the outside in the radial direction D of the annular bus bar 1 and is elastically connected to the connector portion 3. It is comprised so that.

  Further, in the connector-integrated bus bar structure of this embodiment, as shown in FIG. 2, the annular bus bar 1 is provided at a substantially central position of one side surface 7a of the disk-shaped base plate 7 provided inside the electric motor 6. A plurality of inverters 8 are radially arranged around the annular bus bar 1 on the one side surface 7a.

  The connector part 3 and the mating terminal 5 of the conductor 4 elastically connected to the connector part 3 are located between the inverters 8 and 8 arranged adjacent to each other, and in the direction of the axis a, the inverters 8. It extends toward the outer side in the radial direction D along the one side surface 7a so as to be substantially at the same position as the mounted vertical direction.

  Next, the effect of the connector integrated bus bar structure of this embodiment will be described.

  In the connector-integrated bus bar structure of this embodiment, the connector portion 3 bends both end portions 2b and 2c of the long plate-like bus bar base member 2 as a metal plate member which is the same member, It is integrally formed.

  For this reason, it is not necessary to separately use a fixing tool such as a bolt member and a nut member used for fixing as in the prior art, and an increase in manufacturing cost can be suppressed without increasing the number of parts.

  Further, since the bus bar main body 2a and the connector portion 3 are integrally formed by bending the long-plate bus bar base material 2 which is the same material and is the same member, the conductivity is good.

  The bus bar main body 2a has a constant width direction dimension W, and the side surface of the end 2b that constitutes the surface with which the metal contact 5a of the mating terminal 5 is brought into contact with the connector 3 is also constant. The width-direction dimension W is as follows.

  For this reason, the inductance in the width direction of the metal contact 5a of the mating terminal 5 can be made closer to the width direction dimension W to further reduce the inductance.

  And since the other party terminal 5 provided in the said conductor 4 is inserted from the radial direction D outer side, and is connected to the said connector part 3, the space of the outer side or inner side of the elongate bus-bar base material 2 Can be used.

  For example, as shown in FIG. 2 of this embodiment, in the inverters 8... Arranged on one side surface 7a of the base plate 7, it is integrated from the outer surface of the long plate-like bus bar base material 2 toward the outside. The connector part 3 protrudingly formed on the connector part 3 and the mating terminal 5 of the conductor 4 elastically connected to the connector part 3 are arranged between adjacent inverters 8 and 8.

  Therefore, without increasing the dimension of the motor 6 in the direction of the axis a, the connectors 3 and the conductors 4 are connected to the inverters 8 and so on at substantially the same position as the vertical direction in which the inverters 8 are mounted. Similarly, it can be arranged radially outward.
