Description

[Technical Field]

[0001] The present invention relates to a connection device and a generator. [Background technology]

[0002] One example of a generator that converts rotational energy into electrical energy is a generator (called a shaft generator) used on ships. This generator is attached to the shaft that transmits the rotation of the ship's main engine to the propeller, and generates electricity using the main engine as a drive source, which then supplies the generated electricity to the electrical equipment on board.

[0003] This type of generator is equipped with a connection device for connecting to an external cable. The structure of a conventional connection device will now be described with reference to FIGS. 1 and 2. FIG. 1 is a side cross-sectional view of a generator 1 and a connection device 2 provided on the generator 1, as viewed from a predetermined direction. Here, the direction from the left side (motor side) to the right side of FIG. 1 is defined as the X direction, the direction from the bottom to the top is defined as the Z direction, and the direction from the front to the back is defined as the Y direction. FIG. 2 is a side cross-sectional view of the connection device 2, as viewed from the direction indicated by arrow Ar1 in FIG. 1 (from the right side to the left side of FIG. 1).

[0004] As shown in Fig. 1, generator 1 is mainly composed of a stator 3, a rotor 4, a rotating shaft 5, and a frame 6 that covers these. When a prime mover (such as a ship's main engine) rotates rotating shaft 5, which extends in the X direction, generator 1 rotates rotor 4 fixed to rotating shaft 5, causing electromagnetic induction to generate voltage in stator winding 3a provided in stator 3, causing current to flow (i.e., generating electricity).

[0005] As shown in Figures 1 and 2, the connection device 2 is made up of a terminal box 10, busbar supports 11, busbars 12, a connection plate 13, lead cables 14, and external cables 15. The terminal box 10 has a rectangular parallelepiped shape and is attached to the outer periphery of the frame 6 of the generator 1. Busbar supports 11 are attached inside the terminal box 10. The busbar supports 11 are provided at one end and the other end in the X direction inside the terminal box 10. As shown in Figure 2, each busbar support 11 has busbar support portions 11a, 11b, and 11c. The busbar support portions 11a, 11b, and 11c are spaced apart in the Y direction and form steps with the positions increasing in the order of 11a, 11b, and 11c.

[0006] The busbar supports 11a, 11b, and 11c each support a strip-shaped busbar 12 that is long in the X direction from below. That is, the busbar support 11 supports three busbars 12 using three stages of busbar supports 11a, 11b, and 11c. Specifically, the busbar support 11 supports one and the other longitudinal ends of the busbar 12 using the busbar support 11a, and similarly supports one and the other longitudinal ends of the busbar 12 using the busbar supports 11b and 11c.

[0007] One connection plate 13 is fixed to the longitudinal center of each bus bar 12, and external cables 15 are connected by crimp terminals to one end and the other end of each bus bar 12, away from the longitudinal center. Figures 1 and 2 show an example in which four external cables 15 are connected to each of three bus bars 12.

[0008] Connection plate 13 is a member made by bending a strip-shaped conductor into an L shape, and is composed of a portion extending in the Y direction and a portion extending downward from one end of the portion extending in the Y direction. Connection plate 13 is oriented so that the portion extending downward is on the front side of Fig. 1 (left side of Fig. 2), and the portion extending in the Y direction is fixed to the center of bus bar 12 in the longitudinal direction.

[0009] Furthermore, a lead cable 14 is connected to one surface (the surface on the near side in FIG. 1) of the portion of the connection plate 13 that extends downward. This lead cable 14 is a cable drawn out from the stator winding 3a of the generator 1. Note that FIGS. 1 and 2 show an example in which three lead cables 14 are connected to each of three connection plates 13.

[0010] In this way, an external cable 15 is connected to each bus bar 12, and an output cable 14 is connected to each bus bar 12 via the connection plate 13. In other words, the connection device 2 connects the output cable 14 and the external cable 15 via the bus bar 12 and the connection plate 13.

[0011] The connection device 2 has this structure and is configured to supply the current flowing through the stator winding 3a of the generator 1 to external electrical equipment via the lead cable 14 and the external cable 15. Publicly known documents relating to connection devices that connect the lead cable of a generator to an external cable include, for example, Patent Document 1 and Patent Document 2 listed below. [Prior art documents] [Patent documents]

[0012] [Patent Document 1] Jitszen No. 49-122303 [Patent Document 2] Jitszen No. 57-154266 Summary of the Invention [Problem to be solved by the invention]

[0013] In the conventional connection device 2, as shown by the dotted line in FIG. 1, external vibrations can cause the bus bar 12 to bend in the thickness direction, which can cause the external cable 15 and its crimp terminals connected to the bus bar 12 to become detached from the bus bar 12 or to become damaged.

[0014] The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a connection device and a generator that can suppress deflection of bus bars. [Means for solving the problem]

[0015] In order to achieve the above object, a connection device according to the present invention comprises: A connection device for connecting a generator having a stator and a rotor to an external device, The bus bar is a member formed by bending a strip-shaped conductor into a substantially L-shape, and is composed of a first portion and a second portion that is bent in a direction substantially perpendicular to the first portion and is shorter than the first portion. The first portion is supported by the bus bar support, and the first portion has: Connected to the external device An external cable is connected to the second portion, A wire drawn from the stator winding provided on the stator The lead cable is connected, The first portion extends in a first direction, the second portion extends from one end of the first portion in a second direction substantially perpendicular to the first direction, the outlet cable extends along the second direction, and the bus bar support has a cable fixing rib for fixing the outlet cable at a location opposite the outlet cable extending from the second portion of the bus bar. A connection device according to the present invention is a connection device for connecting a generator having a stator and a rotor to an external device, and includes a bus bar, a bus bar support that supports the bus bar, and a base that serves as a foundation. The bus bar is a member formed by bending a strip-shaped conductor into a substantially L-shape and is composed of a first portion and a second portion that is bent in a direction substantially perpendicular to the first portion and is shorter than the first portion. The first portion is supported by the bus bar support. An external cable that is connected to the external device is connected to the first portion, and an output cable drawn from a stator winding provided on the stator is connected to the second portion. The bus bar support is fixed on the base and has a plurality of steps that are different in height from the base, and the plurality of steps support the plurality of bus bars. I made it so that.

[0016] Furthermore, a generator according to the present invention includes the above-described connection device, and the lead cable drawn out from the stator winding is connected to the external cable via the bus bar.

[0017] In the present invention, the bus bar is L-shaped, and a first portion is supported by a bus bar support, and an external cable is connected to the first portion, and an output cable is connected to a second portion bent relative to the first portion.

[0018] By doing so, the present invention eliminates the need to provide an area for fixing the connection plate to the bus bar, allowing the first section to be shortened accordingly. Furthermore, the second section of the bus bar is pulled by the lead cable in a direction from the end closest to the first section to the other end farther away, and this pulls the first section toward the second section. By shortening the first section and causing it to be pulled toward the second section, deflection of the first section can be suppressed, and as a result, external cables and their crimp terminals connected to the first section can be prevented from coming off the bus bar or being damaged. [Effects of the Invention]

[0019] According to the present invention, it is possible to provide a connection device and a generator that can suppress the deflection of a bus bar. [Brief explanation of the drawings]

[0021] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0022] 1. First Embodiment [1-1. Configuration of generator and connection device] First, a first embodiment of the present invention will be described. The structures of a generator 101 according to the first embodiment and a connection device 102 provided on the generator 101 will be described with reference to FIGS. 3 to 5. FIG. 3 is a side cross-sectional view of the generator 101 and the connection device 102 as viewed from a predetermined direction. As with FIG. 1, the direction from the left side (motor side) to the right side of FIG. 3 is the X direction, the direction from the bottom to the top is the Z direction, and the direction from the front to the back is the Y direction. FIG. 4 is a partially enlarged view of the connection device 102 shown in FIG. 3. FIG. 5 is a side cross-sectional view of the connection device 102 as viewed from the direction indicated by arrow Ar1 in FIG. 4 (from the right side to the left side in FIG. 4). That is, FIG. 5 is a side cross-sectional view of the connection device 102 as viewed from a different direction than FIG. 4.

[0023] The generator 101 is used on ships and has a structure similar to that of a conventional generator 1, and is mainly composed of a stator 3, a rotor 4, a rotating shaft 5, and a frame 6 that covers these.

[0024] This generator 101 is configured such that when a rotating shaft 5 extending in the X direction is rotated by a prime mover (such as the main engine of a ship), the rotor 4 fixed to the rotating shaft 5 rotates, and a voltage is generated in the stator winding 3a provided in the stator 3 by electromagnetic induction, causing a current to flow (i.e., generating electricity).

[0025] As shown in Figures 4 and 5, the connection device 102 is made up of a terminal box 110, a base 111, a bus bar support 112, a bus bar 113, an output cable 114, and an external cable 115. The terminal box 110 is box-shaped with an open bottom, and is attached to the generator 101 so as to protrude upward from the upper outer periphery of the frame 6 (see Figure 3). The base 111, the bus bar support 112, the bus bar 113, the output cable 114, and the external cable 115 are provided inside the terminal box 110. The base 111, which serves as a foundation, is a plate-shaped member located at the bottom of the terminal box 110, and is attached to the generator 101 so as to be fixed to the upper outer periphery of the frame 6. The terminal box 110 and the base 111 are separate components.

[0026] Busbar supports 112 are attached to the top surface of base 111. The busbar supports 112 are provided on one end side (the side closer to the prime mover) and the other end side (the side farther from the prime mover) of the top surface of base 111 in the X direction. As shown in FIG. 5, busbar support 112 on one end side and busbar support 112 on the other end side have busbar support portions 112a, 112b, and 112c, respectively. Busbar support portions 112a, 112b, and 112c are provided at intervals in the Y direction, and form steps whose positions increase in the order of 112a, 112b, and 112c. In other words, busbar support 112 has busbar support portions 112a, 112b, and 112c, which are multiple steps whose heights from base 111 are different.

[0027] The bus bar support portions 112a, 112b, and 112c each support a bus bar 113 of the same structure. In other words, the bus bar support 112 supports three bus bars 113 by means of the three stages of bus bar support portions 112a, 112b, and 112c.

[0028] 6 and 7 show enlarged partial views of one of the three bus bars 113. FIG. 6 is an enlarged partial view of the bus bar 113 seen from the same direction as FIG. 4, and FIG. 7 is an enlarged partial view of the bus bar 113 seen from the same direction as FIG. 5. As shown in FIGS. 6 and 7, the bus bar 113 is a member formed by bending a strip-shaped conductor into an L shape, and is composed of a first portion 113a extending in the X direction and a second portion 113b extending downward from one end of the first portion 113a. The second portion 113b is bent downward so as to be substantially perpendicular to the first portion 113a, and is sufficiently short compared to the first portion 113a. Note that "substantially perpendicular" here means, for example, within 90 degrees plus or minus a few degrees.

[0029] 4 and 6, the bus bar supports 112a, 112b, and 112c support one and the other longitudinal ends of the first portion 113a of the bus bar 113 from below, with the second portion 113b of the bus bar 113 oriented closer to the prime mover and the first portion 113a oriented farther from the prime mover. Each bus bar 113 is fixed onto the bus bar supports 112a, 112b, and 112c by, for example, bolts via insulators 116, which are insulating members.

[0030] Each bus bar 113 fixed on the bus bar supports 112a, 112b, 112c in this manner is positioned so that the second portion 113b is closer to the prime mover than the bus bar supports 112a, 112b, 112c closer to the prime mover (i.e., the second portion 113b is positioned outside between the bus bar support 112 on one end side and the bus bar support 112 on the other end side).

[0031] Furthermore, a lead cable 114 is connected to the second portion 113b of each bus bar 113. This lead cable 114 is a cable that is drawn from the stator winding 3a (see FIG. 3) of the generator 101 into the inside of the terminal box 110. In this embodiment, as shown in FIGS. 6 and 7, for example, two lead cables 114 are connected to one surface (the surface on the prime mover side) of the second portion 113b of the bus bar 113, spaced apart in the width direction (Y direction) of the second portion 113b, and two more lead cables 114 are connected to the other surface (the surface opposite to the prime mover side) of each bus bar 113, spaced apart in the Y direction.

[0032] Each lead cable 114 is fixed to the second portion 113b of the bus bar 113 with, for example, a bolt and nut. Each lead cable 114 extends downward from the second portion 113b of the bus bar 113 (i.e., in the extending direction of the second portion 113b). Note that holes (not shown) are provided in the top of the frame 6 of the generator 101 and in the bottom (base 111) of the terminal box 110 attached to the top, and the lead cables 114 pass through these holes to be drawn from inside the frame 6 to inside the terminal box 110.

[0033] 4 and 5, a cable fixing rib 112d is provided on the engine-side surface (outer surface) of the engine-side bus bar support 112 at a location facing the lead cables 114 extending downward from the second portions 113b of the bus bars 113. The lead cables 114 connected to the second portions 113b of each bus bar 113 are fixed to this cable fixing rib 112d, for example, by string tying. As shown in FIG. 5, the cable fixing rib 112d is located below the bus bar supports 112a, 112b, and 112c, and is provided at a position spaced a substantially constant distance from the bus bar supports 112a, 112b, and 112c (in other words, at a position spaced a substantially constant distance from the second portions 113b of the bus bars 113). This cable fixing rib 112d is also provided on the bus bar support 112 on the opposite side from the engine side.

[0034] Furthermore, an external cable 115 is connected to the first portion 113a of each bus bar 113. In this embodiment, as an example, four external cables 115 are connected to one surface (top surface) of the first portion 113a of the bus bar 113 at intervals in the longitudinal direction (X direction) of the first portion 113a.

[0035] Each external cable 115 is fixed to the first portion 113a of the bus bar 113 by, for example, a crimp terminal. Each external cable 115 extends from the first portion 113a of the bus bar 113 in the width direction (Y direction) of the first portion 113a. A hole (not shown) is provided on the side surface of the terminal box 110, and the external cable 115 passes through this hole to be drawn from the inside to the outside of the terminal box 110.

[0036] In this way, the output cable 114 and the external cable 115 are connected to each bus bar 113. In other words, the connection device 102 is configured to connect the output cable 114 and the external cable 115 via the bus bar 113.

[0037] The connection device 102 has such a structure, and supplies the current flowing through the stator winding 3 a of the generator 101 to external electrical equipment via the lead cable 114 and the external cable 115 .

[0038] [1-2. Benefits obtained from the structure of the connection device] Here, we will explain the effects obtained from the structure of connection device 102. As described above, connection device 102 has bus bar 113 in an L-shape composed of first portion 113a and second portion 113b that is bent in a direction approximately perpendicular to first portion 113a and is shorter than first portion 113a. In addition, connection device 102 connects external cable 115 to first portion 113a of bus bar 113, and connects output cable 114 to second portion 113b.

[0039] The first portion 113a extends in the X direction as a first direction, the second portion 113b extends downward as a second direction substantially perpendicular to the first direction, and the outlet cable 114 extends downward from the second portion 113b.

[0040] By doing so, connection device 102 does not need to provide an area for fixing connection plate 13 (see FIG. 1) to bus bar 113, and therefore first portion 113a can be made shorter. Furthermore, in connection device 102, second portion 113b of bus bar 113 is pulled downward (in the direction from one end closer to first portion 113a to the other end farther away) by lead cable 114, and as a result, first portion 113a is pulled toward second portion 113b.

[0041] In this way, connection device 102 shortens first portion 113a of bus bar 113 so that first portion 113a is pulled toward second portion 113b, thereby suppressing deflection of first portion 113a in the thickness direction as shown by the dotted line in Fig. 6. In other words, the structure of connection device 102 makes bus bar 113 less likely to deflect than conventional connection device 2 shown in Fig. 1. As a result, connection device 102 can prevent external cable 115 and its crimp terminal connected to first portion 113a from coming off bus bar 113 or being damaged.

[0042] Furthermore, since the connection device 102 has a structure that omits the connection plate 13, the number of parts can be reduced and the bus bar 113 can be shortened, so that the terminal box 110 can be made smaller in space.

[0043] Furthermore, connection device 102 has a structure in which lead cable 114 is directly connected to bus bar 113, and when external vibration is transmitted to bus bar 113 via external cable 115, lead cable 114 vibrates along with it, thereby consuming the kinetic energy of the external vibration transmitted to bus bar 113, thereby suppressing the vibration of bus bar 113 and making it less likely to bend.

[0044] Furthermore, since the connection device 102 has a structure in which the connection plate 13 is omitted and the lead cable 114 is directly connected to the bus bar 113, it is possible to realize a strong integrated structure that does not cause problems such as the connection plate 13 falling off or the generation of unnecessary vibrations due to loosening of the screw fastening part between the connection plate 13 and the bus bar 12.

[0045] Furthermore, in connection device 102, second portion 113b of bus bar 113 is located outside and between two bus bar supports 112, and output cable 114 is connected to second portion 113b. This allows connection device 102 to easily access output cable 114, improving workability when attaching output cable 114.

[0046] Furthermore, connection device 102 is provided with cable fixing rib 112d at a position a certain distance away from second portion 113b of bus bar 113 in the direction in which output cable 114 extends (downward), and output cable 114 is fixed to cable fixing rib 112d. In this way, connection device 102 can suppress vibration of output cable 114 and prevent output cable 114 from becoming detached from bus bar 113 or being damaged. Also, while there is a conventional method of fixing output cables by filling the inside of a terminal box with a polymer material, connection device 102 of this embodiment is designed to fix output cable 114 more easily than this method.

[0047] Furthermore, as shown in FIG. 8, for example, the connection device 102 has the advantage of being highly versatile, since the direction in which external cables 115 are drawn out can be easily changed to any of four directions corresponding to the four side surfaces of the terminal box 110 simply by changing the orientation of two bus bar supports 112 fixed on the base 111 or by changing the orientation of the bus bars 113 supported by the bus bar supports 112.

[0048] 2. Second Embodiment Next, a second embodiment will be described. This second embodiment is different from the first embodiment in the orientation of external cable 115 relative to bus bar 113. Therefore, here, the bus bar 113 and external cable 115 will be mainly described.

[0049] 9 and 10 show enlarged partial views of one of the three bus bars 113. Note that Fig. 9 is an enlarged partial view of the bus bar 113 seen from the same direction as Fig. 6, and Fig. 10 is an enlarged partial view of the bus bar 113 seen from the same direction as Fig. 7.

[0050] 9 and 10, in the second embodiment, an external cable 115 is connected to an end of the first portion 113a of the bus bar 113 that is farther from the second portion 113b. In the present embodiment, as an example, one external cable 115 is connected to an end of one surface (top surface) of the first portion 113a of the bus bar 113.

[0051] As in the first embodiment, the external cable 115 is fixed to the first portion 113a of the bus bar 113 by, for example, a crimp terminal. The external cable 115 is connected to the other end of the first portion 113a of the bus bar 113 between one end (the side closer to the second portion 113b) and the other end (the side farther from the second portion 113b), and extends in the direction (X direction) from one end to the other end of the first portion 113a.

[0052] In this way, in the second embodiment, the external cable 115 is connected to the other end side (the side farther from the second portion 113b) of the first portion 113a of the bus bar 113. This allows the connection position of the output cable 114 on the bus bar 113 and the connection position of the external cable 115 to be further apart than in the first embodiment, thereby improving the workability when attaching the external cable 115.

[0053] Furthermore, in the second embodiment, the length of the first portion 113a of the bus bar 113 can be made shorter than in the first embodiment, and therefore, deflection of the first portion 113a in the thickness direction can be further suppressed compared to the first embodiment.

[0054] In the second embodiment, since the first portion 113a of the bus bar 113 is short, the bus bar 113 can be supported sufficiently and reliably by simply fixing the central portion in the longitudinal direction of the first portion 113a to the bus bar support 112 (not shown in FIG. 9), as shown in FIG. 9. However, the present invention is not limited to this, and one end and the other end in the longitudinal direction of the first portion 113a may be fixed to the bus bar support 112, as in the first embodiment.

[0055] [3. Other embodiments (modifications)] [3-1. Other embodiment 1] In the first embodiment described above, the lead cables 114 are fixed to the bus bars 113 by bolts and nuts, but this is not limiting, and the lead cables 114 may be fixed to the bus bars 113 by other fixing methods. The same applies to the second embodiment.

[0056] In the first embodiment described above, external cable 115 is fixed to bus bar 113 by a crimp terminal, but this is not limiting, and external cable 115 may be fixed to bus bar 113 by other fixing methods. The same applies to the second embodiment.

[0057] Furthermore, in the first embodiment described above, the bus bars 113 are fixed onto the bus bar supports 112a, 112b, and 112c by bolts via the insulators 116, but this is not limiting and the bus bars 113 may be fixed onto the bus bar supports 112a, 112b, and 112c by other fixing methods. The same applies to the second embodiment.

[0058] Furthermore, in the first embodiment described above, the lead cable 114 is fixed to the cable fixing rib 112d by tying with a string, but this is not limiting, and the lead cable 114 may be fixed to the cable fixing rib 112d by other fixing methods. The same applies to the second embodiment.

[0059] [3-2. Other embodiment 2] Furthermore, in the first embodiment described above, the bus bar 113 is L-shaped and includes a first portion 113a extending in the X direction and a second portion 113b extending downward from one end of the first portion 113a. However, the present invention is not limited to this, and although not shown, the bus bar 113 may be U-shaped and includes a first portion 113a extending in the X direction, a second portion 113b extending downward from one end of the first portion 113a, and a third portion (not shown) extending downward from the other end of the first portion 113a, and the output cable 114 may be connected to one of the second portion 113b and the third portion.

[0060] [3-3. Other embodiment 3] Furthermore, in the first embodiment described above, the bus bar support 112 has a three-step shape, and each step (i.e., bus bar support portions 112a, 112b, and 112c) supports the bus bar 113. However, the present invention is not limited to this, and the bus bar support 112 may have a two-step or four or more-step shape, and each step may support the bus bar 113. Furthermore, the present invention is not limited to this, and the bus bar support 112 may have a shape without steps, and one bus bar support 112 may support one bus bar 113. The same applies to the second embodiment.

[0061] [3-4. Other embodiment 4] Furthermore, in each of the above-described embodiments, the present invention is applied to the generator 101 used on a ship.
