    Description

    [Technical Field]



    [0001] The present invention relates to a motor and, more specifically, to a motor in which a terminal-housing assembly is integrally formed with a bus bar.

    [Background Art]



    [0002] A motor is a device which converts electrical energy into rotational energy using force applied to a conductor in a magnetic field. A conventional motor includes a shaft rotatably formed, a rotor coupled to the shaft, and stators fixed to the housing. The stators are installed along a circumference of the rotor at regular intervals, and coils forming rotating magnetic fields are wound around the stators.

    [0003] In the case of a split core-type stator, a circular bus bar is provided on stators. Coils of the stators are electrically connected to the bus bar via coil terminals. The bus bar includes bus bar terminals connected to power supplies with different polarities.

    [0004] The bus bar terminals are connected to a power terminal for connection with a power cable, and the power terminal is provided on a terminal-housing assembly covering a housing of a motor. The terminal-housing assembly includes a terminal hole in which the power terminal is mounted. Conventionally, the power terminal is installed to be fixed in the terminal hole.

    [0005] When the terminals of the bus bar are assembled to the terminal-housing assembly, it is difficult for the terminals of the bus bar to be aligned and assembled. Also, when the terminal-housing assembly is not positioned at the right place or the power terminal of the terminal-housing assembly is inclined or biased to one side after aligning and assembling, there is a problem in which the terminals of the bus bar may be damaged.

    [0006] WO2014/174666 A1 discloses a fixing member formed of an annular metal material molded integrally with a connecting plate to constitute a connecting plate structure, said connecting plate consisting of a plurality of bus bars and a holder for fixing and holding the bus bars. WO2012/090679 A1 discloses a motor provided with: a stator core; a motor case arranged outside the stator core; and a positioning unit that is formed at a place on the outer face of the stator core, and that is for positioning the stator core with respect to the motor case in the motor rotating direction.

    [0007] JP2009124926 A discloses an electrical motor comprising a bus-bar assembly which is snap fit onto the stator by engaging the snap fit engaging part of the bus-bar assembly with the bobbin mounted axially on the stator core.

    [Modes of the Invention]



    [0024] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Purposes, specific advantages, and novel features of the invention will be made clear from the embodiments and the following detailed descriptions in conjunction with the accompanying drawings. Terms and words used in the description are not to be interpreted as limited to commonly used meanings or meanings in dictionaries and should be interpreted as having meanings and concepts which are consistent with the technological scope of the invention based on the principle that the inventors have appropriately defined concepts of terms in order to describe the invention in the best way. In the description of the invention, detailed descriptions of related well-known functions that unnecessarily obscure the gist of the invention will be omitted. The scope of protection of the invention shall be defined by the appended claims.

    [0025] FIG. 1 is a view illustrating a motor according to comparative example.

    [0026] Referring to FIG. 1, a motor according to a comparative example includes a housing 100, stators 200, a rotor 300, a shaft 400, and a bus bar-terminal assembly 500.

    [0027] The housing 100 has a cylindrical shape and has a space in which the stators 200 and the rotor 300 are mounted. In this case, a shape or material of the housing 100 may be variously changed, but a metal material which is resistant to high temperature may be selected because the housing 100 is mounted in a vehicle. The housing 100 may be configured to shield the stators 200 and the rotor 300 from the outside.

    [0028] The stators 200 are separately disposed on an inner circumferential surface of the housing 100 at regular intervals and may form a central space therein.

    [0029] The rotor 300 may be installed to be rotatable while being accommodated in the central space of the stators 200. The stators 200 may include a plurality of stator cores, and coils forming a rotating magnetic field may be wound around each of the stator cores. The coils wound around the stator cores may be surrounded by an insulator to be insulated. However, the present invention is not limited thereto, and the stators may be formed in a single core form.

    [0030] When a current is supplied to the coils wound around the stators 200, electrical interaction with the rotor 300 is induced to enable the rotor 300 to rotate. When the rotor 300 rotates, the shaft 400 rotates to provide power.

    [0031] FIG. 2 is a view illustrating a bus bar-terminal assembly of the motor illustrated in the FIG. 1. In FIG. 2, only main features are clearly shown for a clear conceptual understanding of the present invention. Accordingly, the present invention may be modified in various forms and may not be limited to the predetermined form illustrated in the drawings.

    [0032] Referring to FIG. 2, the bus bar-terminal assembly 500 includes a bus bar 510 and a body 520. In this case, the bus bar 510, which includes connection terminals 511 connected to the coils wound around the stators 200 and terminals 512 receiving power, is generally disposed on the stators 200 to connect the coils wound around the stators 200 in parallel.

    [0033] The connection terminals 511 are fused to the coils wound around the stators 200 and are connected to the coils, and each of the terminals 512 is connected to phases (U, V, and W) of a three-phase power supply.

    [0034] The bus bar-terminal assembly 500 is integrally formed in the body 520 by the connection terminals 511 and the terminals 512 which are insert-injected being included in the body 520.

    [0035] FIG. 3 is a view illustrating a body of the bus bar-terminal assembly, and FIG. 4 is a view illustrating the bus bar-terminal assembly to be disposed on a stator.

    [0036] Referring to FIGS. 3 and 4, the connection terminals 511 and the terminals 512 are insert-injected and integrally formed in the body 520, and in this case, fusing units of the connection terminals 511 and connection terminals of the terminals 512 protrude from an upper surface of the body 520 to be exposed. Therefore, coils 210 wound around the stators 200 are fused to the connection terminals 511 and connect the power cable to the terminals 512.

    [0037] The body 520 may be formed as a donut-shaped cylindrical body which has an empty center. The fusing units of the connection terminals 511 and the connection terminals of the terminals 512 are disposed on the upper surface of the body 520 to be exposed. The body 520 may have coil grooves 522 formed therein. The coil grooves 522 are formed to penetrate from a lower surface of the body 520 to the upper surface thereof and connection ends 211 of the coils 210 are inserted into the coil grooves 522. The coil grooves 522 may be disposed to be adjacent to the connection terminals 511.

    [0038] The connection end 211 of the coil 210 passing through the coil groove 522 may be directly fused and connected to the connection terminal 511 exposed at the upper surface of the body 520. Six coil grooves 522 may be provided to correspond to six connection terminals included in three connection terminals 511.

    [0039] Terminal housings 521 surrounding the terminals 512 may be formed to protrude from the upper surface of the body 520. Three terminal housings 521 may be provided to correspond to the three terminals 512.

    [0040] FIG. 5 is a view illustrating the bus bar-terminal assembly mounted on the stator.

    [0041] As shown in FIG. 5, when the connection end 211 of the coil 210 is inserted into the coil groove 522, the coil 210 passing through the coil groove 522 is positioned in a fusing area of the connection terminal 511. Thus, a worker can fit the bus bar-terminal assembly 500 with the coil 210 and then immediately perform a fusing task, and therefore, there is an advantage in that assembling is easy.

    [0042] To align and insert the connection end 211 of the coil 210 wound around the stator 200 into the coil groove 522 of the body 520 or to align the housing 100 with the terminal 512, a task of aligning the stator 200 and the bus bar-terminal assembly 500 in a circumferential direction is necessary.

    [0043] To this end, the bus bar-terminal assembly 500 of the motor according to the comparative example includes alignment guide parts 530.

    [0044] Referring to FIGS. 3 to 5, the alignment guide part 530 is formed to be elongated on an outer circumferential surface of the body 520 in a height direction and are formed to be concave or convex to be slide-coupled with and restrained by the housing 100 with respect to the circumferential direction.

    [0045] FIG. 6 is a view illustrating a first embodiment of an alignment guide part.

    [0046] Referring to FIGS. 3 to 6, the alignment guide part 530 is formed on the outer circumferential surface of the body 520 in a slot form to be concave in a radial direction. For example, three alignment guide parts 530 may be disposed on an outer circumferential surface of the body 520 at regular intervals.

    [0047] In this case, slot grooves 220 are formed on an outer circumferential surface of the stators 200, and the alignment guide parts 530 are disposed to be arranged in the slot grooves 220 in the circumferential direction.

    [0048] FIG. 7 is a view illustrating a guide rib of a housing.

    [0049] Referring to FIG. 7, the housing 100 includes guide ribs 110. The guide rib 110 convexly protrudes from an inner side of the housing 100 in a radial direction to be inserted into the alignment guide part 530. The guide rib 110 is disposed to correspond to a position of the alignment guide part 530. In a process of assembling the bus bar-terminal assembly 500, the guide rib 110 may be formed to be smaller than a width of the alignment guide part 530 so that a foreign material is not generated due to friction with the alignment guide part 530. The alignment guide parts 530 may be designed to be relatively larger than a width of the guide rib 110.

    [0050] In this case, when coupling the guide rib 110 and the alignment guide part 530, any one of three guide ribs 110 has a size that tightly fits in the alignment guide part 530 when compared to the other two guide ribs 110 to increase an assembling performance with the housing 100.

    [0051] Meanwhile, the housing 100 may include a cover surface 120 covering an upper surface of the body 520 of the bus bar-terminal assembly 500. The cover surface 120 has a hole 121 in the center thereof so that the shaft 400 passes therethrough, and a terminal slot 130 may be provided around the hole 121. The terminal slot 130 is formed by cutting the cover surface 120 in a radial direction from the hole 121.

    [0052] FIG. 8 is a view illustrating a state in which the housing is mounted on the bus bar-terminal assembly. Referring to FIG. 8, the terminal 512 has to be exposed to the outside of the housing 100 to be connected to an external power cable, and thus the terminal slot 130 ensures a space so that the terminal 512 exposed at the bus bar-terminal assembly 500 can pass therethrough.

    [0053] FIG. 9 is a view illustrating a second modified embodiment of the alignment guide part, and FIG. 10 is a view illustrating a housing including a guide slot.

    [0054] Referring to FIGS. 9 and 10, the alignment guide part 530 is formed in a rib form formed to be convex in a radial direction on the outer circumferential surface of the body 520. For example, the three alignment guide parts 530 may be disposed on the outer circumferential surface of the body 520 at regular intervals.

    [0055] The housing 100 includes guide slots 140. Each of the guide slots 140 protrudes from an inner side of the housing 100 in a radial direction and has the alignment guide part 530 inserted thereinto. The guide slots 140 are disposed to correspond to the positions of the alignment guide parts 530.

    [0056] The motor according to the embodiments of the invention has been described in detail with reference to the accompanying drawings.

    [0057] The above description is only an illustrative description of the technical idea of the present invention, and it should be understood by those of skilled in the art that various changes, modifications, and replacements may be made without departing from the scope of the present invention. Therefore, the exemplary embodiments and accompanying drawings disclosed in the present invention should be considered in a descriptive sense only and not for purposes of limitation. Accordingly, the scope of the invention is not limited by the embodiments. The scope of the invention is defined not by the detailed description of the invention but by the appended claims, and encompasses all modifications and equivalents that fall within the scope of the appended claims.
