Definitions
- the concentrated power distribution member according to the prior art has three bent portions of the coil connection terminal, and as a result, it is inevitable that the size of the concentrated power distribution member in the rotational axis direction is increased. As the concentrated power distribution member becomes larger, as a result, the size of the electric motor in the rotational axis direction also becomes larger.
- FIG. FIG. 1 is a perspective view of an essential part of a stator distribution unit of an electric motor including a centralized power distribution member according to an embodiment of the present invention.
- FIG. 2 is a perspective view of the centralized power distribution member.
- FIG. 3 is a cross-sectional view of the centralized power distribution member taken along line III-III of FIG.
- FIG. 4 is an enlarged perspective view of the main part of the centralized power distribution member.
- FIG. 5 is a plan view of the centralized power distribution member before bending.
- FIG. 6 is a perspective view of a central power distribution member according to another embodiment of the present invention.
- FIG. FIG. 7 is a perspective view from the other direction of the centralized power distribution member main part according to another embodiment of the present invention.
- FIG. 8 is a plan view of the centralized power distribution member prior to folding according to another embodiment of the present invention.
- the U-phase, V-phase, and W-phase bus bars 6 are connected to the power supply wiring of each phase via the bus bar strong electric terminal 5 fixed to the holding member 2.
- each coil connection terminal 3 includes an upright portion 11 extending parallel to the central axis from the bus bar 6 and a pair of arms 12 extending from the upright portion 11 toward the central axis.
- the pair of arms 12 includes a base 12A, a narrowed portion 12B, and a locking portion 12C.
- the coil connection terminal 3 is formed integrally with the bus bar strong electric terminal 5 in advance to the bus bar 6 by cutting out the band-like member 100. That is, as shown in the drawing, wing portions 120 and rising portions 11 constituting the pair of arms 12 are cut out in a shape that protrudes from the bus bar 6 in a substantially T-shape.
- the bus bar high voltage terminals 5 are also cut out so as to protrude in the same direction.
- the bus bar 6 in which the busper strong electric terminal 5 and the plurality of coil connection terminals 3 are integrally formed in advance is bent into a cylindrical shape and fixed to the tubular groove of the holding member 2.
- the busper strong electric terminal 5 is bent 90 degrees toward the central axis of the bus bar 6.
- the bolt holes 7 overlap the screw holes formed at the predetermined positions of the holding member 2, and the bus bars 6 are positioned on the holding member 2 by the bolts passed through the bolt holes 7.
- a concentrated power distribution member composed of the bus bar 6, the bus bar strong electric terminal 5 and the plurality of coil connection terminals 3 integrally formed is prepared for each of the U phase, V phase and W phase, Secure in the corresponding annular groove of. Also.
- a concentrated power distribution member composed of the bus bar 6 and the plurality of coil connection terminals 3 is prepared for the intermediate phase, and fixed to the corresponding annular groove of the holding member 2.
- the length of the pair of arms 12 differs depending on the position of the tubular groove in the holding member 2. As the concentrated power distribution member disposed in the annular groove closer to the outer periphery of the holding member 2, the distance to the coil increases. Therefore, with regard to the concentrated power distribution member disposed in the annular groove near the outer periphery of the holding member 2, the arm 12, in particular, the base 12A of the arm 12 is set long.
- the power distribution unit 1 is fixed to the casing of the motor by the bolts passing through the mounting bosses 4.
- the locking of the coil winding end to the locking portion 12C is performed as follows. That is, in a state in which the end of the winding is guided to the inside of the U-shaped planar locking portion 12C, electrodes are connected to both outer sides of the bifurcated tip 122, and a voltage is applied. The current passes through the proximal end 121 of the locking portion 12C, and generates heat due to the electrical resistance of the proximal end 121. This heat is transferred to the bifurcated tip 122 and melts the coating on the winding ends. The uncoated winding is welded to the bifurcated tip 122 in this manner. This process is called fusing.
- the pair of wing portions 120 extending in both sides is formed in advance in the upstanding portion 11 extending in the rotational axis direction of the motor from the bus bar 6, and the wing portion 120 is bent into a cylindrical shape.
- a pair of arms 12 are formed by bending from a bending line parallel to the central axis of the processed bus bar 6 toward the central axis. Further, a locking portion 12C at the end of the winding is provided at the tip of the pair of arms 12.
- the narrow portion 12B and the proximal end 121 of the locking portion 12C are formed by caulking in the middle of the pair of arms 12, the locking portion 12C for locking the end portion of the winding can be easily formed.
- the concentrated power distribution member including the bus bar 6 and the plurality of coil connection terminals 3 is formed by cutting out the single strip member 100, the concentrated power distribution member can be formed inexpensively.
- the arm 12 is shown in FIG. As shown in FIG. 5, the wing portion 120 is present as a wing portion 120 protruding laterally from the rising portion 11. Therefore, it is not necessary to widen the width of the strip member 100 for forming the arm 12, which also has a preferable effect of reducing the manufacturing cost of the centralized power distribution member.
- FIG. Referring to 6 and 7, the concentrated power distribution member according to this embodiment is provided with a bending portion 15 in one arm 12 of the coil connection terminal 3.
- the crimping step for forming the narrowed portion 12B is not necessary. Further, the projection 150 for the bent portion 15 is formed from the wing portion 120 toward the bus bar 6 when the band-like member 100 is cut out to form the concentrated power distribution member. Therefore, the bent portion 15 can be formed without increasing the width of the strip member 100.
