[0008] [Description of embodiments of the present invention] First, embodiments of the present invention will be described. The terminal block of the present invention, [1] It comprises: a plurality of connecting parts, each connecting a plurality of terminals of a plurality of wires; a busbar, electrically connecting the plurality of connecting parts to each other; and a housing, which houses the plurality of connecting parts and the busbar, the housing having a path limiting part that limits the path of at least one of the plurality of wires.

[0009] According to this structure, at least one of the multiple wires can be stably held in place by the path limiting part of the housing. As a result, the vibration of the wire can be suppressed.

[0010] [2] In the above [1], the plurality of terminals may be fastened to the plurality of connecting parts respectively, and the plurality of connecting parts are configured such that the fixing directions of the plurality of terminals relative to the plurality of connecting parts are the same.

[0011] This structure allows each terminal to be securely fastened to the connecting parts of the terminal block from the same direction. Therefore, it improves the workability of installing each terminal onto the connecting parts of the terminal block.

[0012] [3] In the above [2], the plurality of terminals may also include a first terminal and a second terminal, and the housing has a first configuration portion for configuring the first terminal and a second configuration portion for configuring the second terminal, and at least a portion of the first configuration portion and the second configuration portion overlap in the fixed direction.

[0013] According to this structure, when viewed from the fixed direction of the connection between the terminal and the terminal block, since at least a portion of the first configuration portion and the second configuration portion overlap, the terminal block in the direction orthogonal to the fixed direction can be miniaturized.

[0014] [4] In the above [3], the plurality of connecting parts may include a first connecting part and a second connecting part, the first terminal is connected to the first connecting part, the second terminal is connected to the second connecting part, the first connecting part and the second connecting part are disposed at positions offset from each other in the fixed direction, and when the fixed direction of the terminal relative to the connecting part is taken as the front, the second connecting part is located on the front side of the first connecting part.

[0015] According to this structure, by positioning the second connecting portion forward of the first connecting portion in the fixed direction, a structure can be formed in which the first positioning portion for the first terminal and the second positioning portion for the second terminal overlap. As a result, it is possible to minimize the size of the terminal block in the direction orthogonal to the fixed direction.

[0016] [5] In the above [4], the housing may also have a housing body and a split component assembled to the housing body, the housing body holding the first connecting portion and the second connecting portion, the split component being located between the first configuration portion and the second configuration portion in the fixed direction, and at least a portion of the path limiting portion being disposed on the split component.

[0017] According to this structure, by using the separate component disposed between the first and second configuration sections, interference between the wires connected to the first and second terminals respectively can be suppressed. Furthermore, by providing at least a portion of the path limiting section in the separate component, the path of the wires can be appropriately limited using this path limiting section.

[0018] [6] In the above [5], the plurality of wires may also include a first wire with the first terminal and a second wire with the second terminal, and the path limiting part includes a first path limiting part that limits the path of the first wire and a second path limiting part that limits the path of the second wire, and at least a portion of the first path limiting part and the second path limiting part are provided on the split component.

[0019] According to this structure, the paths of the first wire and the second wire can be restricted respectively by at least a portion of the first path restriction part and the second path restriction part provided on the split component. [7] In any of the above [4] to [6], the first connecting part may include a first bolt held in the housing and a first nut installed on the first bolt, the first terminal being fastened by the first bolt and the first nut, and the second connecting part may include a second nut held in the housing and a second bolt installed on the second nut, the second terminal being fastened by the second nut and the second bolt.

[0020] According to this structure, when installing the first terminal, it can be temporarily held by hooking it onto the first bolt that is held in the housing. This improves the ease of installation of the first terminal. At the second connection, instead of a bolt, a second nut is used to hold it in the housing, thus preventing interference between the second connection and the first wire or the first terminal.

[0021] [8] In any of the above [4] to [7], it may also be that, viewed from the fixed direction, the plurality of wires are led out in the height direction of the terminal block, and the first connecting part and the second connecting part are disposed at positions offset from each other in the height direction.

[0022] According to this structure, the terminal block can be miniaturized in the width direction orthogonal to the height direction. [9] The wire harness of the present invention comprises: a terminal block as described in any one of [1] to [8] above; a plurality of terminals mounted on the terminal block; and a plurality of wires, each having the plurality of terminals.

[0023] Based on this structure, it can achieve the same function as the terminal block mentioned above. [Detailed Description of Embodiments of the Invention] Specific examples of the terminal block and wire harness of the present invention will be described below with reference to the accompanying drawings. In the drawings, for ease of explanation, some parts of the structure are sometimes exaggerated or simplified. Furthermore, the dimensional ratios of the various parts may differ in the drawings. Additionally, the terms "parallel" or "orthogonal" in this specification include not only cases where they are strictly parallel or orthogonal, but also cases where they are substantially parallel or orthogonal to the extent that they serve their function and effect in this embodiment.

[0024] like Figure 1 As shown, the wiring harness W of this embodiment includes a terminal block 10, a first terminal 11 and a second terminal 12 mounted on the terminal block 10, and a first wire 13 and a second wire 14 connected to the first terminal 11 and the second terminal 12, respectively. Furthermore, mutually orthogonal XYZ directions are shown in each figure, and these XYZ directions are referred to as the height direction X, the width direction Y, and the depth direction Z, respectively.

[0025] The wiring harness W is used, for example, in a vehicle. The wiring harness W is, for example, a high-voltage wiring harness in which the cross-sectional area of ​​the conductors of the first wire 13 and the second wire 14 is set to approximately 10 square millimeters or more. The wiring harness W is, for example, located near the engine unit in the engine compartment of the vehicle. The terminal block 10 is, for example, positioned opposite the engine unit in the width direction Y.

[0026] (Terminal 11 and Terminal 22) like Figure 2 As shown, the first terminal 11 and the second terminal 12 are each formed, for example, by stamping a metal sheet. The first terminal 11 is connected to one end of the first wire 13 along its length. The first terminal 11 has a fastening portion 21 and a wire connection portion 22. The fastening portion 21 is fastened to the first connection portion 31 of the terminal block 10, and the first wire 13 is connected to the wire connection portion 22. A through hole 21a is formed in the fastening portion 21, extending through the fastening portion 21 along the thickness direction.

[0027] The second terminal 12 is connected to one end of the second wire 14 along its length. The second terminal 12 has a fastening portion 23 and a wire connection portion 24. The fastening portion 23 is fastened to the second connection portion 32 of the terminal block 10, and the second wire 14 is connected to the wire connection portion 24. A through hole 23a is formed in the fastening portion 23, extending through the fastening portion 23 along the thickness direction. The wire connection portions 22 and 24 of the first terminal 11 and the second terminal 12 are connected to the first wire 13 and the second wire 14, respectively, for example, by crimping.

[0028] The first wire 13 and the second wire 14 each have a core wire (not shown) and an insulating covering portion that encloses the core wire. Each core wire of the first wire 13 and the second wire 14 is electrically connected to the wire connection portions 22 and 24 of the first terminal 11 and the second terminal 12. The first wire 13 and the second wire 14 are each led out from one side (the lower side in this embodiment) of the terminal block 10 in the height direction X to the outside of the terminal block 10.

[0029] (Terminal socket 10) like Figure 1 As shown, the terminal block 10 includes a housing 30, a first connecting portion 31, a second connecting portion 32, and a busbar 33. The first connecting portion 31, the second connecting portion 32, and the busbar 33 are each housed in the housing 30. The first terminal 11 and the second terminal 12 are respectively fastened to the first connecting portion 31 and the second connecting portion 32.

[0030] (First connecting part 31 and second connecting part 32) The first connecting part 31 includes a first bolt 34 held in the housing 30 and a first nut 35 installed on the first bolt 34. The fastening part 21 of the first terminal 11 is fastened together with the busbar 33 by the first bolt 34 and the first nut 35.

[0031] The second connecting part 32 includes a second nut 36 held in the housing 30 and a second bolt 37 mounted on the second nut 36. The fastening part 23 of the second terminal 12 is fastened together with the busbar 33 by the second nut 36 and the second bolt 37.

[0032] like Figure 2As shown, the first connecting portion 31 and the second connecting portion 32 are configured such that their fastening directions D are the same. Specifically, the first bolt 34 of the first connecting portion 31 and the second nut 36 of the second connecting portion 32 are held in the housing 30 with their respective axes L1 and L2 parallel to each other. That is, the mounting direction of the first nut 35 relative to the first bolt 34 and the mounting direction of the second bolt 37 relative to the second nut 36 are the same. Furthermore, the mounting directions of the first nut 35 and the second bolt 37 are, for example, along the depth direction Z of the terminal block 10. The axes L1 of the first bolt 34 and L2 of the second nut 36 are, for example, arranged along the height direction X of the terminal block 10.

[0033] The busbar 33 is formed, for example, by stamping a sheet metal. The busbar 33 has a first through hole 33a and a second through hole 33b. A first bolt 34 is inserted into the first through hole 33a, and a second bolt 37 is inserted into the second through hole 33b. The busbar 33 is electrically connected to the first terminal 11 by tightening the first bolt 34 and the first nut 35. Additionally, the busbar 33 is electrically connected to the second terminal 12 by tightening the second bolt 37 and the second nut 36. Thus, the busbar 33 electrically connects the first connecting portion 31 and the second connecting portion 32 to each other.

[0034] (Shell 30) The housing 30 has a housing body 40 and a separate component 50 assembled to the housing body 40, the housing body 40 holding the first connecting portion 31 and the second connecting portion 32.

[0035] like Figure 4 and Figure 5 As shown, the housing body 40 includes, for example, a frame 41 and a retaining member 42 assembled to the inside of the frame 41. Viewed from the fastening direction D, the frame 41 is, for example, a generally rectangular shape whose length in the height direction X is longer than its length in the width direction Y. The frame 41 forms the outline of the shell 30. That is, viewed from the fastening direction D, the shell 30 is, for example, a generally rectangular shape whose length in the height direction X is longer than its length in the width direction Y.

[0036] The frame 41, for example, has a pair of sidewalls 43 orthogonal to the width direction Y and an upper wall 44 connecting the upper ends of the pair of sidewalls 43 to each other. The frame 41 has a mounting portion 45 for mounting and retaining members 42 on its inner side, which is surrounded by the pair of sidewalls 43 and the upper wall 44. The frame 41 is mounted, for example, at a mounting location (not shown) located in the engine compartment of a vehicle.

[0037] The retaining member 42 is detachably mounted to the mounting portion 45, for example. The retaining member 42 has a first retaining portion 46 for retaining the first bolt 34 and a second retaining portion 47 for retaining the second nut 36. The first bolt 34, retained in the first retaining portion 46, extends from the first retaining portion 46 along the depth direction Z, for example. That is, the first bolt 34 is retained in the first retaining portion 46 with its axis L1 along the depth direction Z. The second nut 36 is retained in the second retaining portion 47 with its axis L2 along the depth direction Z.

[0038] The first retaining portion 46 and the second retaining portion 47 are positioned offset from each other in the depth direction Z of the terminal block 10. When the fastening direction D of the terminal relative to the first connecting portion 31 and the second connecting portion 32 is taken as forward, the second retaining portion 47 is located further forward than the first retaining portion 46. As a result, the second connecting portion 32 held in the second retaining portion 47 is located further forward than the first connecting portion 31 held in the first retaining portion 46.

[0039] The frame 41 has a first extension 48 extending downward. The first extension 48 forms part of the second path limiting part R2, which will be described later. The first extension 48 extends obliquely from the lower part of the frame 41, for example.

[0040] (50 separate parts) like Figure 1 and Figure 3 As shown, the split component 50 is detachably mounted to the frame 41 of the housing body 40. The split component 50 has a main body portion 51 disposed inside the frame 41 and a second extension portion 52 extending from the main body portion 51. The main body portion 51 is disposed between a pair of side walls 43 of the frame 41.

[0041] The main body 51 of the split component 50 has a first path limiting part R1 that limits the path of the first wire 13. The first path limiting part R1 has a pair of wall portions 53. The pair of wall portions 53 are opposite each other, for example, in the width direction Y of the terminal block 10. The first wire 13 passes between the pair of wall portions 53 along the height direction X. Each wall portion 53 is in contact with the first wire 13 or is opposite to the first wire 13 with a small gap. Thus, the path of the first wire 13 is limited by the pair of wall portions 53.

[0042] Each of the pair of wall portions 53 has an elastic sheet 54. Each elastic sheet 54 is, for example, formed at the center of each wall portion 53 in the height direction X. Each elastic sheet 54 can flex in a manner that allows it to shift in the width direction Y. Each elastic sheet 54 has a protrusion 55 that protrudes from each elastic sheet 54 in a direction toward each other.

[0043] The first wire 13 is mounted on the first path limiting part R1 along the depth direction Z. At this time, each elastic piece 54 contacts the first wire 13, causing each elastic piece 54 to shift in a direction of separation. Then, when the first wire 13 is pressed into the appropriate position, each elastic piece 54 elastically returns to its original position. The spacing between the protrusions 55 of each elastic piece 54 is set to be smaller than the diameter of the first wire 13. Therefore, when the first wire 13 is mounted on the first path limiting part R1, the protrusions 55 of each elastic piece 54 prevent the first wire 13 from falling off the first path limiting part R1 in the depth direction Z.

[0044] The second extension 52 of the split component 50 forms part of a second path limiting portion R2 that restricts the path of the second wire 14. The second extension 52 forms a cylindrical second path limiting portion R2 by combining with the first extension 48 of the housing body 40. The second wire 14 is led out to the outside of the housing 30 through the second path limiting portion R2.

[0045] like Figure 4 As shown, in the housing 30, viewed from the fastening direction D (i.e., the depth direction Z) of the first connecting portion 31 and the second connecting portion 32, the first placement portion P1, which is the location for the first terminal 11, and the second placement portion P2, which is the location for the second terminal 12, overlap. Therefore, viewed from the fastening direction D, the first terminal 11 located in the first placement portion P1 and the second terminal 12 located in the second placement portion P2 overlap (see also [reference]). Figure 3 Specifically, viewed from the fastening direction D, the wire connection portion 22 of the first terminal 11 and the fastening portion 23 of the second terminal 12 overlap. Furthermore, the main body portion 51 of the split component 50 is located between the first placement portion P1 and the second placement portion P2 in the fastening direction D. That is, the split component 50 is located between the first terminal 11 and the second terminal 12 in the fastening direction D.

[0046] Next, the assembly method of wire harness W will be explained. First, the second terminal 12, to which the second wire 14 is connected, is fastened together with the busbar 33 using the second nut 36 and the second bolt 37. At this time, the second bolt 37 is installed on the second nut 36 in the tightening direction D.

[0047] Next, the split component 50 is installed onto the housing body 40. As a result, the second terminal 12 and a portion of the second wire 14 are covered by the main body 51 of the split component 50. By installing the split component 50 onto the housing body 40, a second path limiting portion R2 is formed by the first extension 48 of the housing body 40 and the second extension 52 of the split component 50. Furthermore, the second wire 14 is disposed inside the second path limiting portion R2.

[0048] Next, the first terminal 11, to which the first wire 13 is connected, is fastened together with the busbar 33 using the first bolt 34 and the first nut 35. At this time, the first nut 35 is installed on the first bolt 34 in the fastening direction D. In addition, at this time, the first wire 13 is installed on the first path restriction part R1 from the depth direction Z.

[0049] The function of this embodiment will be explained. The path of the first wire 13 is restricted by the first path limiting part R1 of the housing 30. Furthermore, the path of the second wire 14 is restricted by the second path limiting part R2 of the housing 30. Therefore, the vibration of the first wire 13 and the second wire 14 can be suppressed by the first path limiting part R1 and the second path limiting part R2, respectively.

[0050] The first connecting portion 31 and the second connecting portion 32 are configured such that their fastening directions D are the same. As a result, the workability of installing the first terminal 11 and the second terminal 12 onto the first connecting portion 31 and the second connecting portion 32 is improved.

[0051] By positioning the second connecting portion 32 forward of the first connecting portion 31 in the fastening direction D, a structure can be formed in which the first mounting portion P1, which mounts the first terminal 11, and the second mounting portion P2, which mounts the second terminal 12, overlap. As a result, the terminal block 10 in the width direction Y, which is orthogonal to the fastening direction D, can be miniaturized. Thus, for example, even when the mounting space for the terminal block 10 is limited within the engine compartment, the terminal block 10 can be positioned while ensuring clearance from peripheral equipment such as the engine unit.

[0052] The effects of this implementation method will be explained. (1) The housing 30 has a first path limiting part R1 that limits the path of the first wire 13 and a second path limiting part R2 that limits the path of the second wire 14. According to this structure, the first wire 13 and the second wire 14 can be stably held by the first path limiting part R1 and the second path limiting part R2 of the housing 30, respectively. As a result, vibration of the first wire 13 and the second wire 14 can be suppressed.

[0053] (2) The first terminal 11 and the second terminal 12 are respectively fastened to the first connecting portion 31 and the second connecting portion 32 of the terminal block 10. The first connecting portion 31 and the second connecting portion 32 are configured such that their fastening directions D are the same. According to this structure, the first terminal 11 and the second terminal 12 can be fastened to the first connecting portion 31 and the second connecting portion 32 from the same direction. Therefore, the workability when installing the first terminal 11 and the second terminal 12 to the first connecting portion 31 and the second connecting portion 32 can be improved.

[0054] (3) The housing 30 has a first configuration portion P1 for configuring the first terminal 11 and a second configuration portion P2 for configuring the second terminal 12. Viewed from the fastening direction D, the first configuration portion P1 and the second configuration portion P2 overlap. Therefore, the terminal block 10 in the width direction Y, which is orthogonal to the fastening direction D, can be miniaturized.

[0055] (4) The first connecting portion 31 and the second connecting portion 32 are positioned offset from each other in the fastening direction D. When the fastening direction D of the terminal relative to the connecting portion is taken as the front, the second connecting portion 32 is located further forward than the first connecting portion 31. According to this structure, by positioning the second connecting portion 32 further forward than the first connecting portion 31 in the fastening direction D, it is possible to form a structure in which the first placement portion P1 for the first terminal 11 and the second placement portion P2 for the second terminal 12 overlap. As a result, it is possible to minimize the size of the terminal block 10 in the direction orthogonal to the fastening direction D.

[0056] (5) The housing 30 has a housing body 40 and a separate component 50 assembled to the housing body 40, the housing body 40 holding the first connecting portion 31 and the second connecting portion 32. The separate component 50 is located between the first placement portion P1 and the second placement portion P2 in the fastening direction D. According to this structure, by using the separate component 50 disposed between the first placement portion P1 and the second placement portion P2, interference between the first wire 13 and the second wire 14 connected to the first terminal 11 and the second terminal 12, respectively, can be suppressed.

[0057] (6) The entire first path limiting part R1 and a part of the second path limiting part R2 are provided in the split member 50. According to this structure, by providing the first path limiting part R1 and the second path limiting part R2 in the split member 50, the paths of the first wire 13 and the second wire 14 can be appropriately limited by the first path limiting part R1 and the second path limiting part R2 respectively.

[0058] (7) The first connecting portion 31 includes a first bolt 34 held in the housing 30 and a first nut 35 mounted on the first bolt 34. The first terminal 11 is fastened by the first bolt 34 and the first nut 35. The second connecting portion 32 includes a second nut 36 held in the housing 30 and a second bolt 37 mounted on the second nut 36. The second terminal 12 is fastened by the second nut 36 and the second bolt 37. According to this structure, when installing the first terminal 11, it can be temporarily held by hooking the through hole 21a of the first terminal 11 onto the first bolt 34 held in the housing 30. This improves the ease of installation of the first terminal 11.

[0059] Furthermore, if the second connecting portion 32 is configured to be bolted to the housing 30 in the same way as the first connecting portion 31, the bolt protruding from the housing 30 may interfere with the first wire 13 or the first terminal 11. In this respect, in the second connecting portion 32 of this embodiment, instead of a bolt, a second nut 36 is used to hold it to the housing 30, thus preventing the second connecting portion 32 from interfering with the first wire 13 or the first terminal 11.

[0060] (8) The first wire 13 and the second wire 14 are led out to the side of the terminal block 10 in the height direction X. Viewed from the fastening direction D, the first connecting part 31 and the second connecting part 32 are arranged along the height direction X. According to this structure, the terminal block 10 can be miniaturized in the width direction Y, which is orthogonal to the height direction X.

[0061] (Modified Example) This embodiment can be implemented in the following variations. This embodiment and the following variations can be combined with each other within the scope of technical non-contradiction.

[0062] The second connecting part 32, like the first connecting part 31, can also be a structure in which the second bolt 37 is held in the second holding part 47. The first connecting part 31 and the second connecting part 32 may also be arranged in a manner that is aligned along the height direction X or the width direction Y.

[0063] The first configuration part P1 and the second configuration part P2 can also be configured so that they do not overlap when viewed from the fastening direction D. The fastening directions of the first connecting part 31 and the second connecting part 32 may be opposite to each other. In addition, the fastening directions of the first connecting part 31 and the second connecting part 32 may not be parallel.

[0064] The shape and structure of the first path limiting part R1 are not limited to the above embodiments, and can be appropriately modified according to the structure of the terminal block 10. For example, the first path limiting part R1 may also be provided in the frame 41 of the housing body 40.

[0065] The second path restriction part R2 can also be installed in the split part 50 or the housing body 40. The housing 30 may also be a structure without the separate component 50.

[0066] In the terminal block 10, the number of connecting portions for connecting terminals is not limited to the above embodiment, and may be three or more. Consequently, the number of groups of wires and terminals included in the wire harness W may also be three or more.

[0067] In the above embodiment, the first terminal 11 and the second terminal 12 are crimped to the first wire 13 and the second wire 14, respectively, but this is not a limitation. For example, the first terminal 11 and the second terminal 12 can also be connected to the first wire 13 and the second wire 14 by other means such as soldering.

[0068] Terminal block 10 can also be installed in parts of the vehicle other than the engine compartment. like Figure 2 As shown, the busbar 33 can also be a bent plate, including a first flat plate portion having a first through hole 33a, a second flat plate portion having a second through hole 33b, and an intermediate plate portion, which connects the first flat plate portion and the second flat plate portion in a manner that is separated from them by a step in the depth direction Z. The first flat plate portion and the second flat plate portion can be parallel to each other or not on the same plane. The intermediate plate portion can also be orthogonal to both the first flat plate portion and the second flat plate portion. Figure 2 As shown, the fastening portion 21 of the first terminal 11 can also be a plate that overlaps parallel to the first flat plate portion of the busbar 33. The fastening portion 23 of the second terminal 12 can also be a plate that overlaps parallel to the second flat plate portion of the busbar 33. For example... Figure 3 As shown, when the first terminal 11 and the second terminal 12 are fastened to the busbar 33, the through holes 21a, 23a, 33a, and 33b of the first terminal 11, the second terminal 12, and the busbar 33 are arranged in a row, for example, in a row in the height direction X. Figure 3 , Figure 4 As shown, the first path limiting part R1 and the second path limiting part R2 can also cause the first wire 13 and the second wire 14 to extend from the housing 30 in a common plane that can serve as the XZ plane and point in different directions (e.g., in...). Figure 4 The wires are led out from directly below and diagonally to the right of the first wire 13 and a portion of the second wire 14. This structure helps to reduce the amplitude of the swinging of the wires 13 and 14 and helps to thin the terminal block 10, which has multiple densely packed terminals, in the width direction Y.
