Description

Technical Field

[0001] The present invention relates to a connecting device and a generator.

Background Art

[0002] As a generator that converts rotational energy into electrical energy, for example, there is a generator (referred to as a shaft generator) adopted on a ship. This generator is attached to a shaft that transmits the rotation of the main engine (engine) of the ship to the propeller, generates electricity using the main engine as a driving source, and supplies the generated electric power to electrical equipment in the ship.

[0003] This type of generator includes a connecting device for connecting to an external cable. Here, the structure of a conventional connecting device will be described with reference to FIGS. 1 and 2. Note that FIG. 1 is a side cross-sectional view of the generator 1 and the connecting device 2 provided in the generator 1 as viewed from a predetermined direction. Here, the direction from the left side (prime mover side) to the right side of FIG. 1 is the X direction, the direction from the lower side to the upper side is the Z direction, and the direction from the front side to the back side is the Y direction. FIG. 2 is a side cross-sectional view of the connecting device 2 as viewed from the direction indicated by the arrow Ar1 in FIG. 1 (the direction from the right side to the left side of FIG. 1).

[0004] As shown in FIG. 1, the generator 1 mainly includes a stator 3, a rotor 4, a rotating shaft 5, and a frame 6 that covers these. When the 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, and an electric current flows (that is, electricity is generated).

[0005] As shown in Figures 1 and 2, the connection device 2 consists of a terminal box 10, a busbar support 11, a busbar 12, a connecting plate 13, an outlet cable 14, and an external cable 15. The terminal box 10 is rectangular in shape and is attached to the outer circumference of the frame 6 of the generator 1. The busbar support 11 is installed inside the terminal box 10. The busbar support 11 is 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 parts 11a, 11b, and 11c. The busbar support parts 11a, 11b, and 11c are spaced apart in the Y direction and have steps in which the position of 11a, 11b, and 11c increases in height in that order.

[0006] The busbar support sections 11a, 11b, and 11c each support the long, strip-shaped busbar 12 from below in the X direction. In other words, the busbar support 11 supports three busbars 12 with its three stages of busbar support sections 11a, 11b, and 11c. Specifically, the busbar support 11 supports one end and the other end of the busbar 12 in the longitudinal direction with the busbar support section 11a, and similarly, the busbar support sections 11b and 11c support one end and the other end of the busbar 12 in the longitudinal direction, respectively.

[0007] A connecting plate 13 is fixed to the longitudinal center of each busbar 12, and external cables 15 are connected to one end and the other end of each busbar 12 from the longitudinal center using crimp terminals. Figures 1 and 2 show an example in which four external cables 15 are connected to each of the three busbars 12.

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

[0009] Furthermore, a lead cable 14 is connected to one side of the downward-extending portion of the connecting plate 13 (the front side in Figure 1). This lead cable 14 is a cable drawn from the stator winding 3a of the generator 1. Figures 1 and 2 show an example in which three lead cables 14 are connected to each of the three connecting plates 13.

[0010] Thus, each busbar 12 has an external cable 15 connected to it, and a lead cable 14 is connected to it via a connecting plate 13. In other words, the connection device 2 connects the lead cable 14 and the external cable 15 via the busbars 12 and the connecting plate 13.

[0011] The connection device 2 has this structure and supplies 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. For example, prior art documents relating to a connection device for connecting the generator's lead cable and the external cable include Patent Document 1 and Patent Document 2 below. [Prior art documents] [Patent Documents]

[0012] [Patent Document 1] Jitszen No. 49-122303 [Patent Document 2] Jitszen No. 57-154266 [Overview of the Initiative] [Problems that the invention aims to solve]

[0013] Conventional connection devices 2 had a problem in that, as shown by the dotted line in Figure 1, the busbar 12 would bend in the thickness direction due to external vibrations, which could cause the external cable 15 and its crimp terminals connected to the busbar 12 to become detached from or damaged by the busbar 12.

[0014] The present invention was made to solve the above problems, and aims to provide a connecting device and a generator that can suppress the deflection of a busbar. [Means for solving the problem]

[0015] To achieve the above objective, the connection device according to the present invention comprises a busbar, a busbar support for supporting the busbar, a lead cable, and an external cable. The busbar is a member formed by bending a strip-shaped conductor into a substantially L-shape, and consists 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 busbar support, the external cable is connected to the first portion, and the lead cable is connected to the second portion.

[0016] Furthermore, the generator according to the present invention is equipped with the above-described connection device, and the lead cable drawn out from the stator winding and the external cable are connected via the busbar.

[0017] In this invention, the busbar is L-shaped, with the first portion supported by a busbar support, the external cable is connected to the first portion, and the lead cable is connected to the second portion which is bent relative to the first portion.

[0018] In this way, the present invention eliminates the need to provide an area for fixing the connecting plate to the busbar, thereby shortening the first portion. Furthermore, the lead cables pull the second portion of the busbar from one end closer to the first portion to the other end further away, and consequently, the first portion is pulled toward the second portion. By shortening the first portion and causing it to be pulled toward the second portion in this manner, deflection of the first portion can be suppressed, and as a result, external cables and their crimp terminals connected to the first portion can be prevented from coming off or being damaged by the busbar. [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.

Embodiments for Carrying Out the Invention

[0021] Hereinafter, embodiments according to 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. Referring to Figures 3 to 5, the structure of the generator 101 and the connecting device 102 provided on the generator 101 according to the first embodiment will be described. Figure 3 is a side cross-sectional view of the generator 101 and the connecting device 102 when viewed from a predetermined direction. Similar to Figure 1, the direction from the left side (prime motor side) to the right side in Figure 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. Figure 4 is an enlarged partial view of the connecting device 102 shown in Figure 3. Figure 5 is a side cross-sectional view of the connecting device 102 when viewed from the direction indicated by arrow Ar1 in Figure 4 (the direction from the right side to the left side in Figure 4). In other words, Figure 5 is a side cross-sectional view of the connecting device 102 viewed from a different direction than Figure 4.

[0023] The generator 101 is intended for use in ships and has a structure similar to that of conventional generators 1. It mainly consists of a stator 3, a rotor 4, a rotating shaft 5, and a frame 6 that covers them.

[0024] This generator 101 is structured 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), a rotor 4 fixed to the rotating shaft 5 rotates, and a voltage is generated in the stator winding 3a provided on the stator 3 by electromagnetic induction, causing current to flow (i.e., generating electricity).

[0025] As shown in Figures 4 and 5, the connection device 102 consists of a terminal box 110, a base 111, a busbar support 112, a busbar 113, an output cable 114, and an external cable 115. The terminal box 110 is a box-shaped structure with an open bottom and is mounted so as to protrude upward from the upper outer circumference of the frame 6 (see Figure 3) of the generator 101. Inside the terminal box 110 are the base 111, the busbar support 112, the busbar 113, the output cable 114, and the external cable 115. The base 111, which serves as the base, 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 circumference of the frame 6. Note that the terminal box 110 and the base 111 are separate parts.

[0026] A busbar support 112 is attached to the upper surface of the base 111. The busbar support 112 is provided on one end (the side closer to the prime mover) and the other end (the side further from the prime mover) of the upper surface of the base 111 in the X direction. As shown in Figure 5, the busbar support 112 on one end and the busbar support 112 on the other end each have busbar support parts 112a, 112b, and 112c. The busbar support parts 112a, 112b, and 112c are spaced apart in the Y direction and are stepped in the order of 112a, 112b, and 112c, with their positions increasing in that order. In other words, the busbar support 112 has multiple busbar support parts 112a, 112b, and 112c, which are steps of different heights from the base 111.

[0027] The busbar support sections 112a, 112b, and 112c each support a busbar 113 of the same structure. In other words, the busbar support 112 supports three busbars 113 with its three stages of busbar support sections 112a, 112b, and 112c.

[0028] Here, Figures 6 and 7 show enlarged partial views of one of the three busbars 113. Figure 6 is a partially enlarged partial view of the busbar 113 viewed from the same direction as in Figure 4, and Figure 7 is a partially enlarged partial view of the busbar 113 viewed from the same direction as in Figure 5. As shown in Figures 6 and 7, the busbar 113 is a member formed by bending a strip-shaped conductor into an L-shape, and consists 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 approximately perpendicular to the first portion 113a and is sufficiently shorter than the first portion 113a. Here, "approximately perpendicular" means, for example, within 90 degrees ± a few degrees.

[0029] As shown in Figures 4 and 6, the busbar support sections 112a, 112b, and 112c support the first portion 113a of the busbar 113 from below, with the second portion 113b of the busbar 113 facing the side closer to the prime mover and the first portion 113a facing the side further away from the prime mover. Each busbar 113 is fixed to the busbar support sections 112a, 112b, and 112c, for example, by bolts via an insulator 116, which is an insulating member.

[0030] In this manner, each busbar 113 fixed on the busbar support portions 112a, 112b, and 112c is positioned such that the second portion 113b is closer to the prime mover than the busbar support portions 112a, 112b, and 112c on the side closer to the prime mover (that is, the second portion 113b is positioned outside the space between the busbar support 112 on one end and the busbar support 112 on the other end).

[0031] Furthermore, lead cables 114 are connected to the second portion 113b of each busbar 113. These lead cables 114 are cables that are drawn out from the stator winding 3a of the generator 101 (see Figure 3) into the terminal box 110. In this embodiment, as an example, as shown in Figures 6 and 7, two lead cables 114 are connected to one side of the second portion 113b of the busbar 113 (the side facing the prime mover) with a gap in the width direction (Y direction) of the second portion 113b, and two more lead cables 114 are connected to the other side of each busbar 113 (the side opposite to the prime mover) with a gap in the Y direction.

[0032] Each lead cable 114 is fixed to the second portion 113b of the busbar 113, for example, with a bolt and nut. Each lead cable 114 extends downward from the second portion 113b of the busbar 113 (i.e., in the direction of extension of the second portion 113b). Holes (not shown) are provided in the upper part of the frame 6 of the generator 101 and in the bottom (base 111) of the terminal box 110 attached to the upper part, and the lead cables 114 are routed through these holes from the inside of the frame 6 to the inside of the terminal box 110.

[0033] As shown in Figures 4 and 5, a cable fixing rib 112d is provided on the motor-side surface (outer surface) of the motor-side busbar support 112, at a location facing the lead cable 114 extending downward from the second portion 113b of the busbar 113. The lead cable 114 connected to the second portion 113b of each busbar 113 is fixed to this cable fixing rib 112d, for example, by tying it with string. As shown in Figure 5, the cable fixing rib 112d is located below the busbar support portions 112a, 112b, and 112c, and is provided at a position approximately a constant distance from the busbar support portions 112a, 112b, and 112c (in other words, at a position approximately a constant distance from the second portion 113b of the busbar 113). This cable fixing rib 112d is also provided on the busbar support 112 on the opposite side from the motor side.

[0034] Furthermore, an external cable 115 is connected to the first portion 113a of each busbar 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 busbar 113, spaced apart 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 busbar 113, for example, by a crimp terminal. Each external cable 115 extends from the first portion 113a of the busbar 113 in the width direction (Y direction) of the first portion 113a. A hole (not shown) is provided on the side of the terminal box 110, and the external cables 115 are routed through this hole from the inside to the outside of the terminal box 110.

[0036] In this way, each busbar 113 is connected to an outgoing cable 114 and an external cable 115. In other words, the connection device 102 connects the outgoing cables 114 and the external cables 115 via the busbars 113.

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

[0038] [1-2. Effects obtained from the structure of the connecting device] Here, we will explain the effects obtained from the structure of the connection device 102. As described above, the connection device 102 has an L-shaped busbar 113 composed of a first part 113a and a second part 113b that is bent in a direction substantially perpendicular to the first part 113a and is shorter than the first part 113a. Furthermore, the connection device 102 is configured to connect the external cable 115 to the first part 113a of the busbar 113 and the lead cable 114 to the second part 113b.

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

[0040] In this way, the connecting device 102 does not need to provide an area on the busbar 113 for fixing the connecting plate 13 (see Figure 1), and the first portion 113a can be shortened accordingly. Furthermore, the connecting device 102 is pulled downwards by the lead cable 114 (from one end closer to the first portion 113a to the other end further away), and consequently the first portion 113a is pulled toward the second portion 113b.

[0041] In this way, the connector 102 shortens the first portion 113a of the busbar 113, causing it to be pulled toward the second portion 113b, thereby suppressing the deflection of the first portion 113a in the thickness direction, as shown by the dotted line in Figure 6. In other words, the structure of the connector 102 makes the busbar 113 less prone to deflection compared to the conventional connector 2 shown in Figure 1. As a result, the connector 102 prevents the external cable 115 and its crimp terminals connected to the first portion 113a from coming off or being damaged by the busbar 113.

[0042] Furthermore, because the connection device 102 omits the connection plate 13, the number of parts can be reduced and the busbar 113 can be shortened, thus allowing the terminal box 110 to be made more compact.

[0043] Furthermore, the connection device 102 has a structure in which the lead cables 114 are directly connected to the busbar 113. When external vibrations are transmitted to the busbar 113 via the external cable 115, the lead cables 114 vibrate together, consuming the kinetic energy of the external vibrations transmitted to the busbar 113. This suppresses the vibration of the busbar 113 and makes it less prone to bending.

[0044] Furthermore, because the connection device 102 omits the connection plate 13 and connects the lead cables 114 directly to the busbar 113, it is possible to achieve a robust, integrated structure that prevents problems such as the connection plate 13 falling off and the generation of unnecessary vibrations due to loosening of the screw fastening between the connection plate 13 and the busbar 12.

[0045] Furthermore, the connector 102 is configured such that the second portion 113b of the busbar 113 is located outside the two busbar supports 112, and the lead cable 114 is connected to this second portion 113b. This allows the connector 102 to easily access the lead cable 114, improving the workability when installing the lead cable 114.

[0046] Furthermore, the connection device 102 is provided with a cable fixing rib 112d at a position a certain distance away from the second portion 113b of the busbar 113 in the direction in which the lead cable 114 extends (downward), and the lead cable 114 is fixed to the cable fixing rib 112d. In this way, the connection device 102 can suppress vibration of the lead cable 114 and prevent the lead cable 114 from coming off or being damaged from the busbar 113. In addition, there is a conventional method of fixing the lead cable by filling the inside of the terminal box with polymer material, but the connection device 102 of this embodiment allows the lead cable 114 to be fixed more easily compared to such a method.

[0047] Furthermore, the connection device 102 has the advantage of being highly versatile, as it can easily change the direction in which the external cable 115 is routed out to any of the four directions corresponding to the four sides of the terminal box 110 simply by changing the orientation of the two busbar supports 112 fixed on the base 111, or by changing the orientation of the busbar 113 supported by the busbar supports 112, as shown in Figure 8, for example.

[0048] [2. Second Embodiment] Next, a second embodiment will be described. In this second embodiment, the orientation of the external cable 115 relative to the busbar 113 differs from that of the first embodiment. Therefore, this description will mainly focus on the busbar 113 and the external cable 115.

[0049] Figures 9 and 10 show enlarged partial views of one of the three busbars 113. Figure 9 is a partial enlarged view of the busbar 113 viewed from the same direction as in Figure 6, and Figure 10 is a partial enlarged view of the busbar 113 viewed from the same direction as in Figure 7.

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

[0051] The external cable 115 is fixed to the first portion 113a of the busbar 113, for example, by a crimp terminal, similar to the first embodiment. The external cable 115 is also connected to the other end (the side further from the second portion 113b) of the first portion 113a of the busbar 113, and extends along the direction (X direction) from one end to the other end of the first portion 113a.

[0052] Thus, in the second embodiment, the external cable 115 is connected to the other end of the first portion 113a of the busbar 113 (the side furthest from the second portion 113b). By doing so, the connection position of the lead cable 114 on the busbar 113 and the connection position of the external cable 115 can be separated compared to the first embodiment, improving the workability when installing the external cable 115.

[0053] Furthermore, in the second embodiment, the length of the first portion 113a of the busbar 113 can be shortened compared to the first embodiment, so the 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 busbar 113 is shorter, as shown in Figure 9, the busbar 113 can be supported securely by simply fixing the longitudinal central portion of the first portion 113a to the busbar support 112 (omitted in Figure 9). However, this is not limited to this, and as in the first embodiment, one end and the other end of the longitudinal portion of the first portion 113a may also be fixed to the busbar support 112.

[0055] [3. Other Embodiments (Modified Examples)] [3-1. Other Embodiments 1] In the first embodiment described above, the lead cable 114 is fixed to the busbar 113 with bolts and nuts, but the invention is not limited to this, and the lead cable 114 may be fixed to the busbar 113 by other fixing methods. The same applies to the second embodiment.

[0056] Furthermore, in the first embodiment described above, the external cable 115 is fixed to the busbar 113 by crimp terminals, but the external cable 115 may be fixed to the busbar 113 by other fixing methods. The same applies to the second embodiment.

[0057] Furthermore, in the first embodiment described above, the busbar 113 is fixed to the busbar support parts 112a, 112b, and 112c by bolts via the insulator 116, but the invention is not limited to this, and the busbar 113 may be fixed to the busbar support parts 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 was fixed to the cable fixing rib 112d by tying it with thread, but the invention is not limited to this, 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 Embodiments 2] Furthermore, in the first embodiment described above, the busbar 113 is L-shaped, consisting 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. However, it is not limited to this, and although not shown in the figure, the busbar 113 may be U-shaped, consisting of 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, with the lead cable 114 connected to either the second portion 113b or the third portion.

[0060] [3-3. Other Embodiments 3] Furthermore, in the first embodiment described above, the busbar support 112 has a three-step shape, and the busbar 113 is supported by each step (i.e., the busbar support parts 112a, 112b, and 112c). However, the busbar support 112 may have a two-step or four-step or more-step shape, and the busbar 113 may be supported by each step. Also, the busbar support 112 may have a shape without steps, and one busbar support 112 may support one busbar 113. The same applies to the second embodiment.

[0061] [3-4. Other Embodiments 4] Furthermore, in each of the embodiments described above, the present invention was applied to a generator 101 used in a ship. However, the present invention is not limited to this and can be applied to various generators having a structure in which, when the rotating shaft is rotated, a rotor fixed to the rotating shaft rotates, and a voltage is generated in the stator windings provided on the stator by electromagnetic induction, causing a current to flow.

[0062] Furthermore, the present invention is not limited to the embodiments described above. That is, the scope of application of the present invention extends to embodiments that arbitrarily combine some or all of the first and second embodiments and other embodiments, or embodiments that extract some of them.
