The airframe 2 is provided with a tank (hydraulic oil tank) 31 for storing hydraulic oil.

  The connection structure according to the present invention is used for the power transmission mechanism of the work machine 1. Here, this power transmission mechanism will be described as being of a parallel hybrid type. With reference to a perspective view (FIG. 9) showing a schematic arrangement of the power transmission mechanism, the position of the connection structure and the electric device according to the present invention will be described. In the following, the electrical device according to the present invention will be described on the assumption that the first device is the motor / generator 34 and the second device is a control device (for example, an inverter device) that controls the motor / generator 34. More specifically, the connection device according to the present invention will be described as a connection device for electrically connecting the lead wire (lead wire) of the stator (stator) of the motor / generator 34 to the inverter device.

As shown in FIG. 9, the power transmission mechanism includes at least an engine 32, a flywheel 33, and a motor / generator 34. The power transmission mechanism transmits the power of the engine 32 and the power of the motor / generator 34 to a hydraulic pump 35 which is an example of a driven machine, alternatively or in combination.
The engine 32 is a diesel engine, a gasoline engine, or the like. The crankshaft of the engine 32 protrudes toward the hydraulic pump 35, and a flywheel 33 is connected to the tip of the crankshaft (on the hydraulic pump 35 side).

The motor / generator 34 is arranged on the hydraulic pump 35 side of the flywheel 33. The motor / generator 34 has a rotor (rotor) and a stator. As the motor generator 34, a permanent magnet embedded three-phase AC synchronous motor is preferably used, but other types of synchronous motors may be used.

When the motor / generator 34 functions as a generator (generator), the rotor receives the rotational power of the flywheel 33. On the other hand, when the motor / generator 4 functions as an electric motor (motor), the rotor provides rotational power to the flywheel 33. That is, the motor / generator 34 transmits and receives rotational power via the flywheel 33.
The hydraulic pump 35 as a driven machine is driven by receiving power from the engine 32 and / or the motor / generator 34. Specifically, the hydraulic pump 35 may be a hydraulic pump of a hydrostatic transmission.

  In the power transmission mechanism of the working machine 1 having such a schematic arrangement, the connection structure 40 according to the present invention is provided on the hydraulic pump 35 side of the motor / generator 34 as shown in FIG. As shown in FIG. 9, the connection structure 40 is covered with a terminal block cover 42. Although not limited, the socket 41 is attached to the outside of the terminal block cover 42, and the inverter device and the motor / generator 34 are connected via the socket 41.

[Schematic configuration of connection structure]
Next, the connection structure 40 according to the present invention arranged at such a position will be described in more detail. FIG. 1 is a perspective view showing the connection structure 40 with the terminal block cover 42 in FIG. 9 removed. FIG. 2 is a perspective view showing a connection structure 40 in which the resin mold part 45 (terminal block mold part 43 and stator mold part 44) in FIG. 1 is virtually removed. FIG. 3 is a plan view (three views) of the connection structure 40 shown in FIG. FIG. 4 is a perspective view and a plan view of the terminal block 70 (here, the terminal block 70 including the second terminal 60) constituting the connection structure 40. FIG. 5 is a perspective view showing a connection state of terminals in the connection structure 40 (here, a connection state between the first terminal 50 and the second terminal 60). FIG. 6 is an exploded perspective view of the terminal.

  As shown in FIGS. 1 to 6, the connection structure 40 electrically connects the motor generator 34 that is a first device (first electric device) and an inverter device that is a second device (second electric device). It is a connection structure. The connection structure generally includes a first terminal 50 on the motor / generator 34 side, a second terminal 60 on the inverter device side, and a terminal block 70 including the second terminal 60. Here, the first terminal 50, the second terminal 60, the first lead wire 46, and the second lead wire 47 are three-phase AC power (U phase, V phase, W phase) from the inverter device to the stator of the motor / generator 34. To supply 3 each. In the following, the first terminal 50 is the first terminal 50U, the first terminal 50V and the first terminal 50W, the second terminal 60 is the second terminal 60U, the second terminal 60V and the second terminal 60W, and the first lead wire. 46 is distinguished from the first lead wire 46U, the first lead wire 46V and the first lead wire 46W, and the second lead wire 47 is distinguished from the second lead wire 47U, the second lead wire 47V and the second lead wire 47W. The first terminal 50, the second terminal 60, the first lead wire 46, and the second lead wire 47 may be shown without distinguishing the three phases. In particular, reference numerals assigned to structures having the same function are not distinguished including those in the drawings.

  As shown in FIG. 6, the first terminal 50 extends from the first fixing portion 52 and the first fixing portion 52 that fixes the end portion of the first lead wire 46 connected to the motor generator 34. And a first bent portion 56 having an open end bent at a substantially right angle with respect to the direction of the lead wire 46 (bent into an L shape). The first terminal 50 is a general-purpose terminal, and for example, a terminal called a round terminal (round crimp terminal) can be adopted. The second terminal 60 has a second fixing portion 62 that fixes an end portion of the second lead wire 47 connected to the inverter device, and extends from the second fixing portion 62 with respect to the direction of the second lead wire 47. And a second bent portion 66 having an open end bent at a substantially right angle (bent into an L shape). Here, it is assumed that the direction of the second lead wire 47 is the same as the direction of the first lead wire 46. A terminal block 70 is configured including the second terminal 60.

  As shown in FIG. 4, the terminal block 70 has (1) a point provided with a raised portion 68 at the second bent portion 66 of the second terminal 60, and (2) a point provided with an edge portion 75 that prevents resin mold leakage, (3) A general-purpose terminal block can be adopted except that the fins 74 that reinforce the integrity with the resin mold are provided. Note that the first terminal 50 and the second terminal 60 may be terminals other than round terminals, for example, U-shaped, square terminals, or other terminals.

  Further, in this connection structure 40, as shown in FIGS. 5 and 6, the open end side of the first bent portion 56 and the open end side of the second bent portion 66 are brought into contact with each other, as shown in FIGS. Thus, the terminal block 70 is resin-molded and integrated by the terminal block mold portion 43 so as to include the contacted portion and not include the second fixing portion 62. At the time of resin molding, the terminal block mold portion 43 is integrally resin-molded together with the stator mold portion 44 to form a resin mold portion 45 constituted by the terminal block mold portion 43 and the stator mold portion 44.

[Detailed configuration of devices constituting the connection structure]
The first terminal 50, the second terminal 60, and the terminal block 70 that constitute the connection structure 40 will be described in more detail.
As shown in FIG. 6C, the first terminal 50 is a general-purpose round terminal as described above. The first bent portion 56 is bent with respect to the first fixed portion 52 at a bent portion (intermediate portion, boundary portion) 55 at a substantially right angle with respect to the direction of the first lead wire 46. The first fixing portion 52 has an annular edge portion 54 that forms a through hole, and the end portion of the first lead wire 46 is fixed to the through hole. The first bent portion 56 has an annular edge portion 59 that forms a through hole 58, and the first terminal 50 approaches the second terminal 60 in the direction indicated by the arrow X (the access direction may be reversed). A raised portion 68 of the second bent portion 66 is fitted into 58. Therefore, the contact position of the first terminal 50 with respect to the second terminal 60 can be determined by fitting the raised portion 68 of the second bent portion 66 into the through hole 58. That is, the raised portion 68 is a positioning portion that defines the contact position between the first bent portion 56 and the second bent portion 66. In this embodiment, the positioning portion is formed by forming a bulge in the second bent portion 66 of the second terminal 60, but other configurations may be used.

  As shown in FIG. 6C, the second terminal 60 is a terminal included in the general-purpose terminal block 70 as described above. The second bent portion 66 is a bent portion (midway portion, boundary portion) 65 with respect to the second fixed portion 62 and substantially perpendicular to the direction of the second lead wire 47 (same as the direction of the first lead wire 46). It is bent. The second fixing portion 62 has an annular edge portion 64 that forms a through-hole, and a male screw such as a bolt that passes through the through-hole is screwed into a nut 64B shown in FIG. Crimp terminals provided on the terminal block 70 are fixed. As a result, the end portion of the second lead wire 47 is fixed to the second fixing portion 62.

The second bent portion 66 includes a raised portion 68 that is fitted into the through hole 58 of the first bent portion 56.
The raised portion 68 has a substantially cylindrical shape having a chamfered portion 68R and a side surface 69 on the front end surface 68S, and has a diameter that can be fitted into the through hole 58. Note that the raised portion 68 is not limited to a cylindrical shape, and may have any shape as long as it matches the shape of the through hole 58 (first bent portion 56). By fitting the protruding portion 68 into the through hole 58, the first terminal 50 and the second terminal 60 for three phases can be easily positioned. In addition, by providing the chamfered portion 68 </ b> R, the raised portion 68 can be easily fitted into the through hole 58.

  Furthermore, since the side surface 69 contacts the annular edge 59 of the through hole 58, the contact area between the first terminal 50 and the second terminal 60 can be increased, and the electrical resistance can be reduced. From the viewpoint of reducing the electrical resistance, a recess corresponding to the diameter and height of the raised portion 68 is provided in the first bent portion 56 instead of the through hole 58 (occlusion hole instead of the through hole), and the tip It is also preferable to increase the contact area between the first terminal 50 and the second terminal 60 by bringing the surface 68S into contact with the first bent portion 56 (the bottom surface of the depression).

  Thus, after the first terminal 50 and the second terminal 60 for three phases are positioned and contacted, the first terminal 50 and the second terminal 60 are welded, and then resin molded, This procedure will be described later. Here, if the manufacturing cost does not significantly increase and the first terminal 50 and the second terminal 60 for the three phases can be easily positioned, the first terminal 50 has a raised portion. And the second terminal 60 may include a through hole or a blocking hole.

  Next, the terminal block 70 will be described with reference to FIGS. This terminal block is made of a material for ensuring three-phase electrical insulation (for example, a resin having electrical insulation). As shown in FIG. 4, the terminal block 70 has a rectangular mounting portion 71. The attachment portion 71 has a substantially trapezoidal cross section (see FIG. 4B) and has a stepped portion 72. The step portion 72 has a shape corresponding to the size of the crimp terminal provided on the end portion of the second lead wire 47 connected to the second terminal 60 while the second terminal 60 is attached. As shown in FIG. 3, the terminal block 70 is resin-molded by the terminal block molding portion 43 so as not to include the second fixing portion 62 of the second terminal 60 attached to the stepped portion 72.

  Further, the terminal block 70 includes an edge portion (extension portion) 75 on the periphery of the attachment portion 71 on the first terminal 50 side. The edge portion (extending portion) 75 extends in the direction opposite to the second bent portion 66 from at least the boundary portion 55 between the second fixed portion 62 and the second bent portion 66. The edge portion (extending portion) 75 is a protrusion that protrudes outward from the outer surface on which the stepped portion 72 is formed in the attachment portion 71. The terminal block 70 includes a substantially prismatic fin 74 serving as a three-phase partition so as to extend toward the first terminal 50 side of the mounting portion 71. Further, the terminal block 70 includes a guard 73 so as to extend in parallel with the fins 74 toward the first terminal 50 side of the mounting portion 71. As shown in FIG. 3, the terminal block 70 including the fins 74 and the guard 73 is resin-molded by the terminal block molding portion 43. In order to prevent the resin leakage when forming the resin mold, and to realize the integration of the terminal block 70 and the terminal block mold portion 43 after forming the resin mold, The size is set.

[Connecting structure manufacturing procedure]
A manufacturing procedure of the connection structure 40 according to the present embodiment using the terminal block 70 including the first terminal 50 and the second terminal 60 having the above-described configuration will be described.
First, the first terminal 50 for three phases is moved closer to the direction indicated by the arrow X in FIG. 6C toward the terminal block 70 having the second terminals 60 for three phases. In this case, when the first terminal 50 contacts the second terminal 60, the raised portion 68 of the second bent portion 66 is fitted into the through hole 58. For this reason, the first terminal 50 for three phases and the second terminal 60 for three phases can be easily positioned. Furthermore, since the side surface 69 contacts the annular edge 59 of the through hole 58, the contact area between the first terminal 50 and the second terminal 60 can be increased, and the electrical resistance can be reduced.

In a state where the first terminal 50 and the second terminal 60 are positioned, the first terminal 50 and the second terminal 60 are welded. At this time, the raised portion 68 fitted in the through hole 58 is crushed, and the first terminal 50 and the second terminal 60 are firmly integrated.
In this case, the first terminal 50 and the second terminal 60 are welded to form a connection portion only with the metal constituting the terminal, and a substance other than the metal constituting the terminal (particularly mold resin) is interposed. Therefore, the electrical resistance can be reduced. Furthermore, even if the resin is press-fitted at a high pressure during the resin molding described later, the first terminal 50 and the second terminal 60 are welded, and the resin does not enter between the terminals. For this reason, it is possible to prevent the resin from entering between the terminals and increasing the electrical resistance to cause abnormal heat generation or the like. Furthermore, even if the resin is press-fitted at a high pressure during the resin molding described later, the raised portion 68 fitted in the through hole 58 is crushed and the first terminal 50 and the second terminal 60 are firmly integrated. The first terminal 50 and the second terminal 60 do not come off.

  In a state where the first terminal 50 and the second terminal 60 are welded together, the second terminal includes the first terminal 50 and the second terminal 60, includes the fin 74 and the guard 73, and is attached to the stepped portion 72. The terminal block 70 is resin-molded by the terminal block molding portion 43 so as not to include the second fixing portion 62 of the 60. At this time, not only the terminal block mold portion 43 but also the stator mold portion 44 is resin-molded to form a resin mold portion 45 in which the terminal block mold portion 43 and the stator mold portion 44 are integrated. At this time, a mold for forming the resin mold part 45 (the terminal block mold part 43 and the stator mold part 44) is set, and the resin is press-fitted into the mold.

  In this case, since the mold can be positioned using the edge part (extension part) 75 (because the position of the terminal block 70 in the mold can be made accurate and constant), the molding defect rate of the resin mold can be increased. Can be reduced. Furthermore, the edge 75 formed on the terminal block 70 can prevent the resin from leaking out from the edge 75, so that the molding defect rate of the resin mold can be reduced. Furthermore, since the terminal block mold part 43 is formed including the fins 74, the contact area between the terminal block 70 and the resin can be increased, and the fixing strength between the terminal block 70 and the resin can be improved.

As described above, according to the connection structure according to the present embodiment,
(A) The first terminal 50 and the second terminal 60 are bent at a substantially right angle with respect to the direction of the lead wire (bent into an L-shape), and the bent portions are welded to each other to be connected. The working machine can be downsized because the length in the pull-out direction can be shortened.
(B) Since general-purpose terminals and terminal blocks can be used, manufacturing costs can be reduced. (C) Since the terminals and terminal blocks are integrated and resin molded, the connection structure can be reduced in size. Since the base is resin-molded, resin is molded from the inside of the lead wire composed of many copper wires that occurs when the lead wire is resin-molded and the lead wire drawn from the resin mold is connected to the terminal block. Can be prevented from leaking.

The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
For example, in the above-described embodiment, the lead wire is extracted in a direction parallel to the rotor rotation axis, but may be in another direction. In the above-described embodiment, the positioning of the first terminal and the second terminal is a combination of the raised portion and the through hole. However, the outer shape of the terminal may be used.
