[0009] [Description of Embodiments of the Invention] First, embodiments of the present invention will be described by way of examples. The terminal of the present invention, (1) The terminal is connected to a busbar having an arm extending from a busbar body, wherein the terminal comprises: a wire connecting portion, to which a wire is electrically connected; a busbar fixing portion, which is fixed to the busbar body or the arm and electrically connected thereto; and an alignment portion, which aligns the terminal relative to the arm, the busbar fixing portion being disposed between the wire connecting portion and the alignment portion. According to the above structure, since the alignment portion is not interposed between the busbar fixing portion and the wire connecting portion, the busbar fixing portion can be located near the wire connecting portion. Therefore, when an external force acts on the wire connecting portion due to vibration of the wire, etc., a large bending moment can be avoided in the busbar fixing portion. Therefore, even if an external force acts on the wire connecting portion, the fixing function of the busbar fixing portion can be maintained. In addition, since the alignment portion is aligned with the arm, the connection position of the busbar fixing portion relative to the busbar can be determined at an appropriate position.

[0010] (2) Preferably, the positioning portion is fixed to the arm. According to the above configuration, since the fixing function of the positioning portion is added to the fixing function of the bus bar fixing portion, the terminal can be stably fixed to the bus bar.

[0011] (3) Preferably, the positioning portion includes a positioning reference portion aligned at the same position as the end surface of the arm. According to the above configuration, when the terminal is connected to the bus bar, the terminal can be easily positioned relative to the bus bar based on the position of the positioning reference portion.

[0012] (4) Preferably, the positioning portion includes a positioning reference portion at a position facing the end surface of the arm so as to be in contact with the end surface. According to the above configuration, when the terminal is connected to the bus bar, the position where the positioning reference portion contacts the end surface of the arm can be used as a reference for positioning, so that the terminal can be automatically positioned relative to the bus bar.

[0013] (5) A terminal and bus bar connection structure, comprising the terminal and the bus bar as described in any one of (1) to (4) above, wherein the arm comprises: an arm body extending from one end face to the other end face; and a connecting portion extending in a direction intersecting with the extending direction of the arm body, connecting the arm body and the bus bar body, the alignment portion being arranged on the one end face side of the arm body, and the bus bar fixing portion being arranged on the other end face side of the arm body. According to the above configuration, when connecting the terminal to the bus bar, the positioning portion and the bus bar fixing portion can be easily arranged on the arm.

[0014] [Details of Embodiments of the Invention] Specific examples of the present invention are described below with reference to the drawings. The present invention is not limited to the examples, but is shown by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0015] <Implementation Method 1> like Figure 1 As shown in FIG. 1 , the terminal 10 of the first embodiment of the present invention is a terminal interposed between the bus bar 80 and the electric wire 60, and constitutes a bus bar module together with the bus bar 80. In the following description, the front-to-back direction is Figure 1 The right side is the front side, and the up and down directions are Figure 4 The upper side of the upper side is the upper side. The left side is the left side when viewed from the front. Figure 1-Figure 6 In each of the drawings, "front side", "left side" and "upper side" are represented by reference symbols X, Y and Z. These direction references are for convenience and do not necessarily coincide with the direction references in a state where the vehicle is mounted on a vehicle (not shown).

[0016] (electric wire) The electric wire 60 of the first embodiment extends from, for example, a voltage detection device (not shown), and is connected to the terminal 10 at the terminal end facing forward. Figure 1 and Figure 4 As shown, the electric wire 60 is a covered electric wire in which the outer periphery of a conductor 61 composed of a core wire or the like is covered with a covering portion 62 composed of an insulating resin. At the terminal end of the electric wire 60, the covering portion 62 is removed to expose the conductor 61.

[0017] (Bus Bar) The bus bar 80 of the first embodiment is exemplified as a bus bar welded to electrode terminals protruding from a plurality of batteries provided in a power supply device, which are not shown. The power supply device may be a power supply device installed in an electric vehicle, a hybrid vehicle, etc., and supplying electric power to an electric motor.

[0018] The bus bar 80 is a plate made of conductive metal, such as Figure 1 As shown, there is a bus bar body 81 and an arm 82 protruding from the bus bar body 81. The bus bar body 81 is in the shape of a rectangular flat plate, with the plate surface facing the vertical direction. Two through holes 83 are formed in the bus bar body 81 for passing the protruding portions of the electrode terminals. In addition, the opening shapes of the through holes 83 shown in the figure are different, but they may also be the same opening shape.

[0019] The arm 82 is relatively smaller than the bus bar body 81, and is bent from the bus bar body 81 and extends long. Figure 2 As shown, the arm 82 includes: an arm body 84, which is arranged at a distance from an edge (left side edge) of the bus bar body 81 and extends in the front-to-back direction in parallel with the edge of the bus bar body 81; and a connecting portion 85, which extends in the left-right direction and connects an edge of the bus bar body 81 and the arm body 84.

[0020] The arm body 84 has a U-shaped cross section and has: a bent portion 86 bent downward in the middle portion in the left-right direction; a first arm portion 87 rising from the right side of the bent portion 86 (the side close to the bus bar body 81); and a second arm portion 88 rising from the left side of the bent portion 86 (the side away from the bus bar body 81). Figure 4 As shown, the arm body 84 is arranged above the bus bar body 81 via the connection portion 85 .

[0021] like Figure 2 As shown, the connection portion 85 is in a bent plate shape, protrudes upward from one edge of the bus bar body 81 , extends leftward, and further bends downward from the left end portion to be connected to the upper end surface of the front end portion of the first arm portion 87 .

[0022] (terminal) The terminal 10 is a plate made of conductive metal and has a shape extending long in the front-to-back direction. Figure 1 As shown, the terminal 10 is arranged in parallel with an edge of the busbar body 81 with a gap therebetween. The terminal 10 has a positioning portion 11 at the front end portion (the end portion on one end face side (front end face side)), a wire connecting portion 12 at the rear end portion (the end portion on the other end face side (rear end face side)), and a busbar fixing portion 13 between the positioning portion 11 and the wire connecting portion 12. Figure 4 As shown in FIG. 1 , the terminal 10 has a base 14 extending over the entire length in the front-to-back direction. The base 14 constitutes the bottom wall portion of each of the alignment portion 11, the wire connection portion 12, and the busbar fixing portion 13, and is formed into a shape in which the central portion in the left-right direction is bent downward by crimping described later (see FIG. 1 ). Figure 5 and Figure 6 ).

[0023] The electric wire connecting portion 12 includes a wire barrel portion 15 connected to the conductor 61 of the electric wire 60 by crimping, and an insulating barrel portion 16 connected to the coating portion 62 of the electric wire 60 by crimping. Figure 1 As shown, the wire barrel portion 15 is arranged in the front-to-back direction with the insulating barrel portion 16 at the front side of the insulating barrel portion 16. The wire barrel portion 15 and the insulating barrel portion 16 respectively have barrel pieces 17 and 18 that stand up from the left and right sides of the base portion 14 and are opposed to each other. Each barrel piece 17 of the wire barrel portion 15 is crimped and fixed to the outer periphery of the conductor 61 of the electric wire 60 and is electrically connected to the conductor 61. Each barrel piece 18 of the insulating barrel portion 16 is crimped and fixed to the outer periphery of the covering portion 62 of the electric wire 60 and is mechanically connected to the covering portion 62.

[0024] like Figure 1 and Figure 3 As shown, the alignment portion 11 is arranged corresponding to the front end of the arm body 84. The front end surface of the alignment portion 11 is arranged so as to be aligned at the same position with the front end surface of the arm 82, more specifically, the front end surface of the arm body 84 and the front end surface of the connecting portion 85. In the case of the first embodiment, the front end surface of the alignment portion 11 constitutes the alignment reference portion 19, which serves as a reference for aligning the terminal 10 with respect to the bus bar 80.

[0025] like Figure 5 As shown, the alignment portion 11 has an alignment piece 21 that stands up from the left side of the base 14. The base 14 of the alignment portion 11 is arranged to face the lower surface of the bent portion 86 of the arm body 84. The portion of the alignment piece 21 other than the upper end portion is arranged to face the left side surface of the second arm portion 88. The upper end portion of the alignment piece 21 is bent toward the right by crimping, and is arranged to face the upper end surface of the front end portion of the second arm portion 88. In the case of the first embodiment, the upper end portion of the alignment portion 11 contacts the upper end surface of the front end portion of the second arm portion 88, and is arranged in a manner that the front end portion of the arm body 84 is sandwiched between the base 14 in the up-down direction.

[0026] like Figure 5 As shown in FIG. 1 , the positioning portion 11 is formed to be curved as a whole. A retreat space 22 into which a connection portion between the connection portion 85 and the first arm portion 87 enters is formed between both ends of the positioning portion 11 in the circumferential direction.

[0027] like Figure 1 and Figure 3 As shown, the bus bar fixing portion 13 is arranged corresponding to the rear end portion (hereinafter referred to as the fixed portion 89) of the arm body 84. The bus bar fixing portion 13 has fixing pieces 23 that stand up from both left and right sides of the base portion 14 so as to face each other.

[0028] like Figure 6 As shown, each fixing piece 23 is bent into a curved shape by crimping, and the bent end faces downward, and is arranged opposite to each other in a manner of butting against each other at the left and right middle parts of the terminal 10. Each fixing piece 23 contacts the arm body 84 in a manner of respectively rolling up the first arm portion 87 and the second arm portion 88 in the fixed portion 89, and is arranged in a manner of sandwiching the fixed portion 89 between the base 14 in the vertical direction. The bent end surface of each fixing piece 23 enters the space formed between the first arm portion 87 and the second arm portion 88 in the fixed portion 89.

[0029] (effect) When connecting the terminal 10 to the busbar 80, first, the base 14 of the busbar fixing portion 13 is arranged below the fixed portion 89 of the arm body 84, and the base 14 of the alignment portion 11 is arranged below the front end portion of the arm body 84. Furthermore, the fixing pieces 23 that stand up before crimping are arranged on the left and right sides of the fixed portion 89 of the arm body 84, and the alignment piece 21 that stands up before crimping is arranged on the left side of the front end portion of the second arm portion 88. Here, using vision or a jig, the alignment reference portion 19 is aligned with the front end surface of the arm 82 (the front end surface of the arm body 84 or the front end surface of the connecting portion 85) at the same front-to-back position (refer to Figure 3 ) In other words, the positioning reference portion 19 and the front end surface of the arm 82 are arranged on a reference line along the left-right direction.

[0030] Next, the bus bar fixing portion 13 is pressed against the fixed portion 89 of the arm body 84, and the alignment portion 11 is pressed against the front end portion of the arm body 84. In the first embodiment, the bus bar fixing portion 13 and the alignment portion 11 can be pressed against each other simultaneously or separately in a state where the bus bar fixing portion 13 and the alignment portion 11 are aligned by the alignment reference portion 19. Thus, each fixing piece 23 can be pressed against and fixed to the fixed portion 89 of the arm body 84 at an appropriate position, and the alignment piece 21 can be pressed against and fixed to the front end portion of the arm body 84 at an appropriate position.

[0031] Before or after the crimping operation of the bus bar fixing portion 13 and the positioning portion 11, it is preferable that the conductor 61 and the covering portion 62 at the terminal of the electric wire 60 are connected to the wire barrel portion 15 and the insulating barrel portion 16 of the electric wire connecting portion 12, respectively.

[0032] However, when the wire 60 is wound or laid, if the wire 60 is pulled or vibrated and an external force in a direction intersecting the front-rear direction is applied from the wire 60 to the terminal 10, the external force is transmitted from the wire connection portion 12 to the bus bar fixing portion 13, and sometimes a bending moment is generated in the bus bar fixing portion 13. Here, when a large bending moment is generated in the bus bar fixing portion 13, the bus bar fixing portion 13 may be deformed. However, in the case of the first embodiment, as Figure 1 As shown, the bus bar fixing portion 13 and the wire connecting portion 12 are arranged adjacent to each other without the alignment portion 11. Therefore, even if the above-mentioned external force acts, the bending moment generated in the bus bar fixing portion 13 can be suppressed to a small value. As a result, the bus bar fixing portion 13 can be prevented from being deformed, and the fixing function of the bus bar fixing portion 13 relative to the bus bar 80 can be maintained.

[0033] In addition, by aligning the front end surface of the arm 82 and the positioning reference portion 19 of the terminal 10 at the same front-back position, the terminal 10 can be aligned with respect to the bus bar 80 before the crimping operation. As a result, the connection position (crimping position) of the terminal 10 with respect to the bus bar 80 can be appropriately determined.

[0034] Furthermore, in the case of the first embodiment, the positioning portion 11 also has a function of fixing the bus bar 80 in order to assist the bus bar fixing portion 13 , so that the terminal 10 can be stably fixed to the bus bar 80 .

[0035] <Implementation Method 2> Figure 7-Figure 9 The structure of the positioning portion 11 of the terminal 10A of the second embodiment of the present invention shown is different from that of the first embodiment. The rest is the same as the first embodiment. In addition, in the following description, the same reference numerals are attached to the parts having the same functions as those of the first embodiment (not limited to the same shapes), and repeated descriptions are omitted. Figure 7-Figure 9 In the drawings, the reference characters X, Y, and Z represent “front side”, “left side”, and “upper side”, respectively.

[0036] like Figure 7 As shown in FIG. 1 , the alignment portion 11 includes an alignment piece 21 rising from the left side of the base 14 and a stopper 25 disposed forward of the alignment piece 21. Fig. 9As shown, the stopper 25 has stopper pieces 26 that stand up from the left and right sides of the base 14 and face each other. Each stopper piece 26 is continuously bent from the base 14 into a curved shape, with the bent end facing downward, and is arranged opposite to the position of the left and right middle parts of the terminal 10A. The cross-sectional shape of each stopper piece 26 is the same as the cross-sectional shape of each fixing piece 23 of the bus bar fixing part 13. However, each stopper piece 26 is not in a shape that is crimped to the bus bar 80, and the inner side of each stopper piece 26 is hollow.

[0037] like Figure 7 As shown, the rear end surface of each stopper piece 26 is configured as a positioning reference portion 19, and the positioning reference portion 19 faces the front end surface of the arm body 84 from the front side so as to be contactable.

[0038] Before connecting the terminal 10B to the bus bar 80, the pre-stop portion 25 is bent into the above-mentioned shape in advance. In this state, the base 14 of the bus bar fixing portion 13 is arranged below the fixed portion 89 of the arm body 84, and the base 14 of the alignment portion 11 is arranged below the front end portion of the arm body 84. In addition, the fixing pieces 23 that stand up before crimping are arranged on the left and right sides of the fixed portion 89 of the arm body 84, and the alignment piece 21 that stands up before crimping is arranged on the left side of the front end portion of the arm body 84. At this time, the alignment reference portion 19 of the stop portion 25 is arranged forward of the front end surface of the arm body 84. Next, the terminal 10A is moved backward relative to the arm body 84. As a result, the alignment reference portion 19 of the stop portion 25 contacts the front end surfaces of the first arm portion 87 and the second arm portion 88, respectively, and the movement operation of the terminal 10A relative to the arm body 84 stops (refer to Figure 7 and Figure 8 Thus, in the subsequent crimping process, each fixing piece 23 of the bus bar fixing portion 13 can be crimped and fixed to the fixed portion 89 of the arm body 84 at an appropriate position, and the aligning piece 21 of the aligning portion 11 can be crimped and fixed to the front end of the arm body 84 at an appropriate position.

[0039] In the case of the second embodiment, since the bus bar fixing portion 13 and the wire connecting portion 12 are arranged adjacent to each other, the bending moment generated in the bus bar fixing portion 13 can be suppressed to be small when an external force acts on the wire connecting portion 12, as in the first embodiment described above. As a result, the fixing function of the bus bar fixing portion 13 with respect to the bus bar 80 can be maintained.

[0040] According to the second embodiment, when the terminal 10A is connected to the bus bar 80 , the position where the positioning reference portion 19 and the front end surface of the arm 82 contact each other can be used as a reference for positioning, so that the terminal 10A can be naturally positioned relative to the bus bar 80 .

[0041] <Implementation Method 3> Fig.10 The structures of the positioning portion 11 and the bus bar 80 of the terminal 10B in the third embodiment of the present invention are different from those in the first embodiment. In the following description, the same reference numerals are given to the parts having the same functions as those in the first embodiment (not limited to the same shapes), and repeated descriptions are omitted. Fig.10 In the drawings, reference characters X, Y, and Z respectively represent “front side,” “left side,” and “upper side.”

[0042] The terminal 10B is shaped to extend in the left-right direction, and has an alignment portion 11 at the right end, a wire connection portion 12 at the left end, and a bus bar fixing portion 13 at the left-right middle portion. The terminal 10B has a base portion 14 extending over the entire length in the left-right direction. The base portion 14 constitutes the bottom wall portion of each of the alignment portion 11, the wire connection portion 12, and the bus bar fixing portion 13.

[0043] The positioning portion 11 has a plate piece 27 that stands up from the front side of the right end side of the base portion 14. The positioning portion 11 of the third embodiment does not have a function of fixing the bus bar 80.

[0044] The bus bar body 81 has an extended fixed portion 89 on one edge of the bus bar body 81. The arm 82 is arranged in front of the fixed portion 89. The arm 82 is in an L-shaped plate shape when viewed from above, and is formed in a shape that protrudes to the left from one edge of the bus bar body 81 and further extends to the rear from the left end side. The rear end surface of the arm 82 is arranged close to the fixed portion 89 with a gap. A recessed portion 91 for receiving the plate piece 27 is formed in the rear end surface of the arm 82 in the form of a cutout.

[0045] In the case of the third embodiment, before the terminal 10B is connected to the busbar, the plate piece 27 is preliminarily formed to stand upright. In this state, the base 14 of the busbar fixing portion 13 is arranged below the left end of the fixed portion 89, and the base 14 of the lower alignment portion 11 is arranged below the right end of the fixed portion 89. Furthermore, each fixing piece 23 that stands upright upward before crimping is arranged on both sides of the front and rear of the left end of the fixed portion 89. Furthermore, the plate piece 27 is fitted into the inner side of the recess 91 of the arm 82. Thus, the connection position (crimping position) of the terminal 10B relative to the busbar 80 can be determined. Then, each fixing piece 23 of the busbar fixing portion 13 is crimped to the fixed portion 89 of the busbar body 81.

[0046] In the case of the third embodiment, the bus bar fixing portion 13 can be fixed to the bus bar body 81 instead of the arm 82. In addition, the terminal 10B can be positioned relative to the arm 82 by the positioning portion 11 having a simple shape and having no fixing function.
