The terminal block is used with the base body tilted so that the first end is located lower than the second end. A plurality of first ribs extending in the first direction are provided at the first end, and one or more second ribs extending in the first direction are provided at the second end. The number of first ribs is greater than the number of second ribs.

[0011] Furthermore, the terminal block disclosed herein includes a base body and a terminal held in the base body. The base body has a through hole for bolt fastening, a first end, and a second end. The first end is an end of the base body in a second direction perpendicular to a first direction along the through hole.

[0022] [Description of embodiments of this disclosure]

[0023] First, embodiments of this disclosure will be described.

[0024] The terminal block disclosed herein,

[0025] [1] The terminal block has a base body and a terminal held in the base body. The base body has a through hole for bolt fastening, a first end and a second end. The first end is an end of the base body in a second direction perpendicular to a first direction along the through direction of the through hole. The second end is an end of the base body on the side opposite to the first end in the second direction. The terminal block is used with the base body tilted so that the first end is located lower than the second end. A plurality of first ribs extending in the first direction are provided at the first end. One or more second ribs extending in the first direction are provided at the second end. The number of first ribs is greater than the number of second ribs.

[0026] According to this structure, the strength of the first end, which is subjected to a special load due to the tilting posture of the seat body, can be effectively improved by using the first rib, which has more ribs than the second rib. As a result, deformation of the first end can be effectively suppressed.

[0027] [2] The through hole includes a first through hole and a second through hole. The first through hole is disposed at the first end and extends along the first direction. The second through hole is disposed at the second end and extends along the first direction. Two first through holes are arranged in a direction perpendicular to the first direction and intersecting the second direction, and two second through holes are arranged in a direction perpendicular to the first direction and intersecting the second direction. The first rib is a rib disposed between the two first through holes, and the second rib is a rib disposed between the two second through holes. According to this structure, the strength of the first end can be improved more appropriately.

[0028] [3] The first rib includes a rib that extends along the second direction when viewed from the first direction.

[0029] According to this structure, the strength of the first end can be improved more appropriately. Furthermore, the first rib can function as a guide when water adhering to the upper surface of the first end is discharged towards the outer edge of the first end in the second direction.

[0030] [4] The first rib includes a third rib, which, when viewed from the first direction, is shaped along the periphery of the first through hole and covers the second end side of the first through hole when viewed from the first direction. In the seat body, the side of the third rib relative to the second direction of the first through hole is taken as the inner side, and the opposite side of the inner side is taken as the outer side in the second direction. There is no rib facing the third rib in the second direction on the outer side of the first through hole in the second direction.

[0031] According to this structure, the strength around the first through hole at the first end can be improved by using the third rib. Furthermore, the third rib can suppress water immersion in the first through hole and the bolt installed in it. Additionally, no rib facing the third rib is provided on the outer side of the first through hole in the second direction. Therefore, at the first end, water adhering to the area around the first through hole can be easily drained outwards in the second direction.

[0032] [5] The second rib includes a fourth rib, which, when viewed from the first direction, is shaped along the periphery of the second through hole and covers the first end side of the second through hole when viewed from the first direction. A straight line orthogonal to the central axis of the second through hole and along the second direction is used as a reference line. The side of the fourth rib on the second through hole side includes a separating surface that is separated from the second through hole as it moves away from the reference line.

[0033] According to this structure, the gap between the bolt installed in the second through hole and the partition surface of the fourth rib widens as it moves away from the baseline. Therefore, the partition surface facilitates the drainage of water that has seeped into the gap between the bolt and the fourth rib.

[0034] [6] A plurality of terminals are arranged along the second direction.

[0035] According to this structure, in a terminal block with multiple terminals, shortening can be achieved in directions orthogonal to both the first and second directions.

[0036] [7] The first end has a bottom wall with an upper surface, and the first rib extends from the upper surface of the bottom wall in the first direction. The bottom wall has a drainage portion that is shaped such that the upper surface is shifted from the second end side toward the first end side to the lower surface side. According to this structure, the drainage portion allows water adhering to the upper surface of the first end to be properly discharged toward the outer edge of the first end in the second direction.

[0037] [8] The upper surface of the drainage section is in a stepped shape that shifts from the second end side toward the first end side to the lower surface side.

[0038] This structure improves the ease of demolding of the molding die during the molding of the seat body. As a result, it contributes to the improved formability of the seat body.

[0039] [9] A recess for mounting a sealing member is provided on the lower surface of the bottom wall, the recess being located on the lower surface of the bottom wall at a position that does not cross the step of the drainage section.

[0040] According to this structure, the lower surface of the bottom wall with the concave portion can be shaped into a stepped shape along the upper surface of the drainage portion. Therefore, the thickness of the bottom wall plate can be made as uniform as possible. As a result, deformations such as shrinkage marks that may occur due to plate thickness variations can be suppressed in the bottom wall.

[0041] In addition, the terminal block disclosed herein,

[0042]

[10] The terminal block has a base body and a terminal held in the base body. The base body has a through hole for bolt fastening, a first end and a second end. The first end is an end of the base body in a second direction perpendicular to a first direction along the through direction of the through hole. The second end is an end of the base body on the side opposite to the first end in the second direction. The terminal block is used with the base body tilted so that the first end is located below the second end. The first end has one or more first ribs extending in the first direction, and the second end does not have any ribs extending in the first direction.

[0043] According to this structure, the strength of the first end, which is subjected to a special load due to the tilted posture of the seat body, can be effectively increased by utilizing the first rib. As a result, deformation of the first end can be effectively suppressed.

[0049] (Structure of terminal block 10)

[0050] Figure 1 and Figure 2 The terminal block 10 of this embodiment shown is assembled onto the assembly surface A of a machine mounted on a vehicle. For example... Figure 2 As shown, the assembly surface A is inclined relative to the direction of gravity G. That is, the terminal block 10 is inclined relative to the direction of gravity G when assembled on the assembly surface A. In the assembled state, the terminal block 10 is inclined at approximately 20 degrees, for example. Furthermore, the machine is, for example, a drive motor used in electric vehicles, hybrid vehicles, etc.

[0051] like Figure 1 As shown, the terminal block 10 includes a block body 11 and terminals 12 held in the block body 11. The block body 11 is mainly made of, for example, synthetic resin. In addition, the block body 11 is formed, for example, by injection molding.

[0052] Figure 3 The terminal block 10 is shown as viewed from the first direction D1. (Example) Figure 3 As shown, the body 11, viewed from the first direction D1, has a shape that is longer in the second direction D2 than in the third direction D3. The body 11, viewed from the first direction D1, is, for example, roughly rectangular.

[0053] Terminal block 10, for example, has a plurality of terminals 12. The plurality of terminals 12 are arranged, for example, along a second direction D2. One end 12a of terminal 12 in a first direction D1 is connected to a terminal of a counterpart connector (not shown). Furthermore, the terminal of the counterpart connector is connected to terminal 12 from the direction along the first direction D1. In addition, the other end of terminal 12 in the first direction D1 is connected to a terminal provided by the machine.

[0054] One end 12a of terminal 12 in the first direction D1 is surrounded by a peripheral wall portion 13 of the base body 11. The peripheral wall portion 13 extends along the first direction D1. Furthermore, the peripheral wall portion 13 is annular when viewed from the first direction D1. A plurality of terminals 12 are disposed inside the annular peripheral wall portion 13. A retaining portion is fitted into the peripheral wall portion 13, which holds the terminals in the counterpart connector.

[0055] (Structure of the main body 11)

[0056] like Figure 1 and Figure 3 As shown, the seat body 11 has a first end 14 as one end in the second direction D2, and a second end 15 as the end opposite to the first end 14 in the second direction D2. A peripheral wall portion 13 is provided between the first end 14 and the second end 15. Figure 2 As shown, the seat body 11 is assembled on the assembly surface A with the first end 14 located at a lower position than the second end 15.

[0057] like Figure 2 and Figure 3 As shown, the seat body 11 has a first fixing portion 16 fixed to the assembly surface A. Additionally, the seat body 11 has a second fixing portion 17 fixed to the assembly surface A. The first fixing portion 16 is provided, for example, at each end of the first end portion 14 in the third direction D3. The second fixing portion 17 is provided, for example, at each end of the second end portion 15 in the third direction D3. That is, in the seat body 11 of this embodiment, the four fixing portions—two first fixing portions 16 and two second fixing portions 17—are respectively provided at the four corners of the seat body 11 viewed from the first direction D1. Each first fixing portion 16 and each second fixing portion 17 is fixed to the assembly surface A, for example, by bolts. Furthermore, the thickness of the first fixing portion 16 and the second fixing portion 17 in the first direction D1 is thinner than the thickness of the main portion 18 of the seat body 11 in the first direction D1. The main portion 18 of the seat body 11 is the portion between the first end portion 14 and the second end portion 15 of the seat body 11. The peripheral wall portion 13 is located in the main portion 18.

[0058] The base body 11 has a first through hole 21 and a second through hole 22 for bolt fastening. For example, the base body 11 has two first through holes 21. One first through hole 21 is provided in each of the two first fixing portions 16. Additionally, the base body 11 has, for example, two second through holes 22. One second through hole 22 is provided in each of the two second fixing portions 17. A fastening bolt (not shown) is inserted into each of the first through holes 21 and each of the second through holes 22.

[0059] like Figure 4 As shown, the first through hole 21 passes through the first fixing part 16 along the first direction D1. Each of the first through holes 21 is, for example, circular when viewed from the first direction D1. One first through hole 21 is provided at one end of the first end 14 in the third direction D3. The other first through hole 21 is provided at the other end of the first end 14 in the third direction D3. In other words, one first through hole 21 is provided on one side of the third direction D3 relative to the center line L1 of the seat body 11, and the other first through hole 21 is provided on the other side relative to the center line L1.

[0060] Furthermore, in the following description, sometimes the side relative to the center line L1 of the first through hole 21 in the third direction D3 is referred to as "the inner side of the first through hole 21 in the third direction D3", and the opposite side is referred to as "the outer side of the first through hole 21 in the third direction D3". Additionally, in the following description, sometimes the side relative to the second end 15 of the first through hole 21 in the second direction D2 is referred to as "the inner side of the first through hole 21 in the second direction D2", and the opposite side is referred to as "the outer side of the first through hole 21 in the second direction D2".

[0061] The two first through holes 21 are arranged in the third direction D3. That is, the two first through holes 21 are arranged in a direction perpendicular to the first direction D1 and intersecting the second direction D2.

[0062] like Figure 5 As shown, the second through hole 22 passes through the second fixing part 17 along the first direction D1. Each of the second through holes 22 is, for example, circular when viewed from the first direction D1. One second through hole 22 is provided at one end of the second end 15 in the third direction D3. The other second through hole 22 is provided at the other end of the second end 15 in the third direction D3. In other words, one second through hole 22 is provided on one side of the third direction D3 relative to the center line L1 of the seat body 11, and the other second through hole 22 is provided on the other side relative to the center line L1.

[0063] Furthermore, in the following description, sometimes the side relative to the center line L1 of the second through hole 22 in the third direction D3 is referred to as "the inner side of the second through hole 22 in the third direction D3", and the opposite side is referred to as "the outer side of the second through hole 22 in the third direction D3". Additionally, in the following description, sometimes the side relative to the first end 14 of the second through hole 22 in the second direction D2 is referred to as "the inner side of the second through hole 22 in the second direction D2", and the opposite side is referred to as "the outer side of the second through hole 22 in the second direction D2".

[0064] The two second through holes 22 are arranged in the third direction D3. That is, the two second through holes 22 are arranged in a direction perpendicular to the first direction D1 and intersecting the second direction D2.

[0065] Furthermore, each of the first through holes 21 and each of the second through holes 22 is, for example, formed by a cylindrical collar 23. That is, each of the first through holes 21 and each of the second through holes 22 is a hollow portion of the cylindrical collar 23. The collar 23 is formed of a material such as metal, which has a higher rigidity than the synthetic resin constituting the main body 11. Furthermore, the collar 23 is provided, for example, in a manner in which a portion is embedded in the resin portion of each of the first fixing portions 16 and the resin portion of each of the second fixing portions 17.

[0066] (Structure of rib 31)

[0067] like Figure 4 As shown, a plurality of first ribs 31 extending along a first direction D1 are provided at the first end 14 of the seat body 11. The plurality of first ribs 31 include ribs 32 and ribs 33.

[0068] Rib 32 extends from the upper surface of the bottom wall 14a of the first end 14 along the first direction D1. The bottom wall 14a is the part of the first end 14 that connects the two first fixing parts 16 to each other. Furthermore, with respect to the bottom wall 14a, the side on which the rib 32 is provided is designated as the upper side, and the opposite side is designated as the lower side.

[0069] The rib 32, viewed from the first direction D1, extends along the second direction D2. The rib 32 is, for example, a flat plate perpendicular to the third direction D3. For example, two ribs 32 are provided. The two ribs 32 are arranged in the third direction D3. The rib 32 is positioned between the two first through holes 21 in the third direction D3. One of the two ribs 32 is, for example, aligned with the center position of the peripheral wall portion 13 in the third direction D3, and one end of this rib 32 in the second direction D2 is connected to the outer peripheral surface of the peripheral wall portion 13.

[0070] For example, two ribs 33 are provided at the first end 14. Ribs 33 are provided around each of the first through holes 21.

[0071] like Figure 2 and Figure 6 As shown, the resin portion of the first fixing part 16 has an upper surface 16a and a lower surface 16b. The upper surface 16a is, for example, a plane perpendicular to the first direction D1. Furthermore, the upper end of the collar 23, which is one end in the axial direction, protrudes from the upper surface 16a along the first direction D1. The lower surface 16b of the first fixing part 16 faces the assembly surface A. A bolt (not shown) is fixed to the first fixing part 16 from the side of the upper surface 16a. Ribs 33 extend from the upper surface 16a of the first fixing part 16 along the first direction D1.

[0072] like Figure 4 As shown, rib 33, viewed from the first direction D1, has a shape that covers a portion of the circumference of the first through hole 21. Furthermore, rib 33, viewed from the first direction D1, has a shape along the periphery of the first through hole 21. Specifically, rib 33 has a side surface 33a on the side of the first through hole 21. The side surface 33a, along the circumferential direction, is generally arc-shaped with the central axis C1 of the first through hole 21 as its center.

[0073] Each rib 33 has a first portion 34 and a second portion 35. The first portion 34 is located inside the first through hole 21 in the third direction D3. That is, the first portion 34 is located between the two first through holes 21. In addition, each rib 32 is located between the first portions 34 of each rib 33 in the third direction D3.

[0074] The second part 35 is located inside the first through hole 21 in the second direction D2. Viewed from the first direction D1, the second part 35 is shaped to cover the inside of the first through hole 21 in the second direction D2. In both the first part 34 and the second part 35, the side surface 33a of the rib 33 is an arc centered on the central axis C1.

[0075] like Figure 4 and Figure 6 As shown, on the upper surface 16a side of the first fixing part 16, the outer side of the first through hole 21 in the second direction D2 is open. That is, there is no rib on the second direction D2 facing the second part 35 of the rib 33 on the outer side of the first through hole 21 in the second direction D2.

[0076] As described above, the first rib 31 is disposed between the two first through holes 21. In this embodiment, the number of first ribs 31 disposed at the first end 14 is four, consisting of two ribs 32 and two ribs 33.

[0077] like Figure 4 and Figure 7As shown, at the first end 14 of the seat body 11, the bottom wall 14a has a drainage portion 36. The drainage portion 36 is provided, for example, between two ribs 32. Alternatively, for example, the drainage portion 36 is provided between the first portion 34 of the ribs 32 and 33. The drainage portion 36 is formed by shifting the upper surface of the bottom wall 14a from the second end 15 side toward the first end 14 side toward the lower surface side in the direction along the second direction D2. Furthermore, the upper surface of the bottom wall 14a in the drainage portion 36 will be referred to below as the upper surface of the drainage portion 36.

[0078] like Figure 7 As shown, the upper surface of the drainage section 36 has, for example, a stepped shape that shifts downward from the second end 15 side toward the first end 14 side to the lower surface side. Here, a plane perpendicular to the first direction D1 and passing through the lower end of the first through hole 21 is used as the reference plane S. The distance between the upper surface of the drainage section 36 along the first direction D1 and the reference plane S decreases whenever the step of the drainage section 36 is lowered from the second end 15 side toward the first end 14 side.

[0079] A recess 38 for mounting a sealing member 37 is provided on the lower surface of the bottom wall 14a. Furthermore, an annular recess (not shown) that is circular when viewed from the first direction D1 is provided on the lower surface of the seat body 11; the recess 38 is a circumferential part of this annular recess. The sealing member 37 is mounted in this annular recess. Figure 3 The annular sealing member 37 is shown. With the terminal block 10 assembled on the assembly surface A, the sealing member 37 is disposed in a compressed state between the lower surface of the block body 11 and the assembly surface A. Thus, the sealing member 37 seals the terminal block 10 and the assembly surface A.

[0080] like Figure 7 As shown, in the lower surface of the bottom wall 14a, the recess 38 is in the shape of a groove extending along the third direction D3. Furthermore, the recess 38 is positioned corresponding to a step in the stepped drainage section 36. That is, the recess 38 is positioned in the lower surface of the bottom wall 14a without crossing the step of the drainage section 36. In this embodiment, the drainage section 36 is composed of three layers: an upper layer, a middle layer, and a lower layer, and the recess 38 is provided corresponding to the middle layer of the drainage section 36. Additionally, in the first direction D1 and the second direction D2, the outer edge 38a of the recess 38 and the boundary portion 36a of the step of the drainage section 36 substantially overlap.

[0081] (Structure of rib 41)

[0082] like Figure 5 As shown, a plurality of second ribs 41 extending in the first direction D1 are provided at the second end 15 of the seat body 11. The plurality of second ribs 41 include ribs 42 and ribs 43.

[0083] Rib 42 extends from the bottom wall 15a of the second end 15 along the first direction D1. The bottom wall 15a is the part of the second end 15 that connects the two second fixing parts 17 to each other. Furthermore, with respect to the bottom wall 15a, the side on which the rib 42 is provided is designated as the upper side, and the opposite side is designated as the lower side.

[0084] The rib 42, viewed from the first direction D1, extends along the second direction D2. The rib 42 is, for example, a flat plate perpendicular to the third direction D3. For example, one rib 42 is provided. The rib 42 is positioned between the two second through holes 22 in the third direction D3. The rib 42 is, for example, positioned at the center of the peripheral wall portion 13 in the third direction D3. Furthermore, one end of the rib 42 in the second direction D2 is connected to the outer peripheral surface of the peripheral wall portion 13.

[0085] For example, two ribs 43 are provided at the second end 15. Ribs 43 are provided around each of the second through holes 22.

[0086] like Figure 2 As shown, the resin portion of the second fixing part 17 has an upper surface 17a and a lower surface 17b. The upper surface 17a is, for example, a plane perpendicular to the first direction D1. Furthermore, the upper end of the collar 23, which is one end in the axial direction, protrudes from the upper surface 17a along the first direction D1. The lower surface 17b of the second fixing part 17 faces the assembly surface A. A bolt (not shown) is fixed to the second fixing part 17 from the side of the upper surface 17a. Ribs 43 extend from the upper surface 17a of the second fixing part 17 along the first direction D1.

[0087] like Figure 5 As shown, rib 43, viewed from the first direction D1, has a shape that covers a portion of the circumference of the second through hole 22. Furthermore, rib 43, viewed from the first direction D1, has a shape along the periphery of the second through hole 22. Specifically, rib 43 has a side surface 43a on the side of the second through hole 22. The side surface 43a, in the circumferential direction, is generally arc-shaped with the central axis C2 of the second through hole 22 as its center.

[0088] Each rib 43 has a first portion 44 and a second portion 45. The first portion 44 is located inside the second through hole 22 in the third direction D3. That is, the first portion 44 is located between the two second through holes 22. In the first portion 44, the side surface 43a of the rib 43 is arc-shaped with the central axis C2 as the center. In addition, the rib 42 is located between the first portions 44 of each rib 43 in the third direction D3.

[0089] The second part 45 of rib 43 is located inside the second through hole 22 in the second direction D2. The second part 45 is shaped to cover the inside of the second through hole 22 in the second direction D2 when viewed from the first direction D1.

[0090] The side surface of the second part 45 on the side of the second through hole 22 is configured as a partition surface 46. The partition surface 46 is, for example, a plane perpendicular to the second direction D2. That is, the partition surface 46 is a surface that extends along the third direction D3 when viewed from the first direction D1. The second part 45 and its partition surface 46 extend, for example, to the outer edge of the second fixing part 17 in the third direction D3. Here, a straight line orthogonal to the central axis C2 of the second through hole 22 and along the second direction D2 is taken as the reference line L2. On the outside of the second through hole 22 in the third direction D3, the partition surface 46 separates from the second through hole 22 as it moves away from the reference line L2 along the third direction D3. That is, the gap between the second through hole 22 and the second part 45 increases as it moves outward toward the second through hole 22 in the third direction D3.

[0091] On the upper surface 17a side of the second fixing part 17, the outer side of the second through hole 22 in the second direction D2 is open. That is, there is no rib in the second direction D2 facing the second part 45 of the rib 43 on the outer side of the second through hole 22 in the second direction D2.

[0092] As described above, the second rib 41 is disposed between the two second through holes 22. In this embodiment, the number of second ribs 41 disposed at the second end 15 is three, consisting of one rib 42 and two ribs 43. That is, the seat body 11 is configured such that the number of first ribs 31 is greater than the number of second ribs 41.

[0093] The effects of this implementation method will be explained.

[0094] (1) In the seat body 11, the number of first ribs 31 provided at the first end 14, which is inclined downward, is greater than the number of second ribs 41 provided at the second end 15, which is inclined upward. According to this structure, the strength of the first end 14, which is subjected to a special load due to the inclined posture of the seat body 11, can be effectively improved by using more first ribs 31 than second ribs 41. As a result, deformation of the first end 14 can be effectively suppressed.

[0095] (2) The main body 11 has through holes including a first through hole 21 and a second through hole 22. The first through hole 21 is provided at the first end 14 and extends along the first direction D1. The second through hole 22 is provided at the second end 15 and extends along the first direction D1. Two first through holes 21 are arranged in a direction perpendicular to the first direction D1 and intersecting the second direction D2. Two second through holes 22 are arranged in a direction perpendicular to the first direction D1 and intersecting the second direction D2. Furthermore, a first rib 31 is a rib provided between the two first through holes 21, and a second rib 41 is a rib provided between the two second through holes 22. According to this structure, the strength of the first end 14 can be more appropriately improved.

[0096] (3) The first rib 31 surrounds the rib 32, which extends along the second direction D2 when viewed from the first direction D1. According to this structure, the strength of the first end 14 can be improved more appropriately. Furthermore, the rib 32 can function as a guide when water adhering to the upper surface of the first end 14 is discharged toward the outer edge of the first end 14 in the second direction D2.

[0097] (4) The first rib 31 includes a rib 33, which, when viewed from the first direction D1, is shaped along the periphery of the first through hole 21. The second portion 35 of the rib 33, when viewed from the first direction D1, is shaped to cover the second end 15 side of the first through hole 21. In the seat body 11, the side of the second portion 35 relative to the first through hole 21 in the second direction D2 is designated as the inner side, and the opposite side is designated as the outer side in the second direction D2. No rib facing the second portion 35 is provided on the outer side of the first through hole 21 in the second direction D2. According to this structure, the strength around the first through hole 21 at the first end 14 can be improved by using the rib 33. In addition, the rib 33 can suppress water immersion in the first through hole 21 and the bolt installed in the first through hole 21. Furthermore, no rib facing the second portion 35 of the rib 33 is provided on the outer side of the first through hole 21 in the second direction D2. Therefore, at the first end 14, water adhering to the periphery of the first through hole 21 can be easily discharged to the outside of the second direction D2.

[0098] (5) The second rib 41 includes a rib 43, which, when viewed from the first direction D1, is shaped along the periphery of the second through hole 22. The second portion 45 of the rib 43, when viewed from the first direction D1, is shaped to cover the first end 14 side of the second through hole 22. Taking a straight line orthogonal to the central axis C2 of the second through hole 22 and along the second direction D2 as a reference line L2, the side surface 43a of the rib 43 on the side of the second through hole 22 includes a partition surface 46 that separates from the second through hole 22 as it moves away from the reference line L2. According to this structure, the gap between the bolt installed in the second through hole 22 and the partition surface 46 of the rib 43 can be widened as it moves away from the reference line L2. Therefore, the partition surface 46 can facilitate the drainage of water that has seeped into the gap between the bolt and the rib 43.

[0099] (6) Multiple terminals 12 are arranged along the second direction D2. According to this structure, in the terminal block 10 having multiple terminals 12, shortening in the third direction D3 can be achieved.

[0100] (7) The first end portion 14 has a bottom wall 14a, which has an upper surface. A first rib 31 extends from the upper surface of the bottom wall 14a in a first direction D1. Furthermore, the bottom wall 14a has a drainage portion 36, which is shaped such that its upper surface is shifted from the second end portion 15 side toward the first end portion 14 side toward the lower surface side. According to this structure, the drainage portion 36 can be used to properly drain water adhering to the upper surface of the first end portion 14 toward the outer edge of the first end portion 14 in a second direction D2.

[0101] (8) The upper surface of the drainage section 36 has a stepped shape that shifts from the second end 15 side toward the first end 14 side to the lower surface side. According to this structure, the demolding ease of the molding die when molding the seat body 11 can be improved. As a result, it can help improve the formability of the seat body 11.

[0102] (9) A recess 38 for mounting the sealing member 37 is provided on the lower surface of the bottom wall 14a. The recess 38 is provided in the lower surface of the bottom wall 14a at a position that does not cross the step of the drainage section 36. According to this structure, the lower surface of the bottom wall 14a having the recess 38 can be set into a stepped shape along the upper surface of the drainage section 36. Therefore, the thickness of the bottom wall 14a can be set to be as uniform as possible. As a result, deformation such as shrinkage marks that may occur due to thickness deviation can be suppressed in the bottom wall 14a.

[0103] This embodiment can be implemented with the following modifications. This embodiment and the following modifications can be combined with each other within the scope of technical inconsistency.

[0104] Alternatively, the recess 38 can be provided in the lower surface of the bottom wall 14a at a position that crosses the step of the drainage section 36. Alternatively, the recess 38 can be omitted from the lower surface of the bottom wall 14a. In this case, the entire lower surface of the drainage section 36 can be made into a plane perpendicular to the first direction D1.

[0105] The upper surface of the drainage section 36 can be any shape that shifts downward from the second end 15 side toward the first end 14 side to the lower surface side. That is, in the above embodiment, the upper surface of the drainage section 36 is provided as a shape that shifts downward in a stepped manner from the second end 15 side toward the first end 14 side to the lower surface side. However, it is not limited to a stepped shape, and the upper surface of the drainage section 36 may also be a tapered surface that slopes downward from the second end 15 side toward the first end 14 side to the lower surface side.

[0106] • Alternatively, the drainage section 36 can be omitted from the bottom wall 14a, and the upper surface of the bottom wall 14a can be similarly set as a plane perpendicular to the first direction D1.

[0107] • The configuration of the multiple terminals 12 is not limited to the above-described embodiment. For example, the terminals 12 may also be arranged along the third direction D3.

[0108] In the above embodiment, the side surface 43a of the rib 43 includes a partition surface 46 that is separated from the second through hole 22 as it moves away from the reference line L2. However, it is not limited to this, and the side surface 43a may also be formed as an arc centered on the central axis C2 of the second through hole 22.

[0109] The number of first ribs 31 provided at the first end 14 and the number of second ribs 41 provided at the second end 15 are not limited to the above embodiment. The number of each can be appropriately changed according to the structure of the seat body 11, provided that the number of first ribs 31 is greater than the number of second ribs 41.

[0110] ·like Figure 8 As shown, the number of ribs provided at the second end 15 can also be set to zero, that is, the second end 15 is configured without ribs extending in the first direction D1. In this case, the number of the first ribs provided at the first end 14 can also be one. According to this structure, the strength of the first end 14, which is particularly subjected to load due to the tilting posture of the seat body 11, can also be effectively improved by using the first rib 31. As a result, deformation of the first end 14 can be effectively suppressed.

[0111] The number of first through holes 21 provided at the first end 14 and the number of second through holes 22 provided at the second end 15 are not limited to the above embodiment and can be appropriately changed according to the structure of the base body 11. For example, the number of first through holes 21 provided at the first end 14 may be one or more. In addition, the plurality of first through holes 21 may not be arranged along the third direction D3. Similarly, the plurality of second through holes 22 may not be arranged along the third direction D3.

[0112] In the seat body 11 of the above embodiment, the second direction D2 of the first end 14 and the second end 15 is specified to be consistent with the long side direction of the seat body 11. However, it is not limited to this, for example, the second direction D2 of the first end 14 and the second end 15 may be specified to be consistent with the short side direction of the seat body 11.

[0113] In the above embodiment, the shape of the seat body 11 viewed from the first direction D1 is such that it is longer in the second direction D2 than in the third direction D3. However, it is not limited to this; for example, it may be configured such that it is longer in the third direction D3 than in the second direction D2, or that the dimensions of the second direction D2 and the third direction D3 are approximately equal.

[0114] • The tilt angle of the base body 11 fixed to the assembly surface A is not limited to the above embodiment and can be appropriately changed according to the structure of the other machine side.

[0115] ·like Figures 1-4 As shown in Figure 6, the outermost surface of the first fixing part 16 may also be a part of the outermost surface of the seat body 11. The upper surface 16a of the first fixing part 16 may also be directly continuous with the outermost surface of the seat body 11, for example, without any steps. For example, the seat body 11 may not have a recess that could be a groove and / or a protrusion that could be a wall between the upper surface 16a of the first fixing part 16 and the outermost surface of the seat body 11. The upper surface 16a of the first fixing part 16 may also be directly continuous with the outermost surface of the collar 23, for example, without any steps. For example, the seat body 11 may not have a recess that could be a groove and / or a protrusion that could be a wall between the upper surface 16a of the first fixing part 16 and the outermost surface of the collar 23. The seat body 11, configured so that its upper surface 16a of the first fixing part 16 (between the outermost side of the collar 23 and the outermost side of the seat body 11) does not have a recess or protrusion that obstructs the flow of water, has the following advantage: when water adheres to the upper surface 16a of the first fixing part 16, the water easily flows outward from the upper surface 16a of the first fixing part 16 toward the outermost side of the seat body 11 due to gravity and / or surface tension. Even if, for example, the seat body 11 is in a horizontal position, water sometimes easily flows outward from the upper surface 16a of the first fixing part 16 toward the outermost side of the seat body 11, for example, due to surface tension.

[0116] ·like Figure 2 , 3 As shown in Figure 5, the outermost surface of the second fixing part 17 can also be part of the outermost surface of the seat body 11. The upper surface 17a of the second fixing part 17 can also be directly continuous with the outermost surface of the seat body 11, for example, without any steps. In addition, the upper surface 17a of the second fixing part 17 can also be directly continuous with the outermost surface of the collar 23, for example, without any steps. For example, the seat body 11 can also not have a recess that can be a groove and / or a protrusion that can be a wall between the upper surface 17a of the second fixing part 17 and the outermost surface of the collar 23. The seat body 11 configured so that there are no recesses or protrusions that hinder the flow of water on the upper surface 17a of the second fixing part 17 (between the outermost surface of the collar 23 and the outermost surface of the seat body 11) has the advantage that when water adheres to the upper surface 17a of the second fixing part 17, the water can easily flow outward from the upper surface 17a of the second fixing part 17 towards the outermost surface of the seat body 11, for example, due to gravity. Even if, for example, the seat body 11 is in a horizontal position, water may sometimes flow outward from the upper surface 17a of the second fixing part 17 towards the outermost side of the seat body 11, for example, due to surface tension.

[0117] The base body 11 is sometimes referred to as a synthetic resin platform or an insulating resin platform. The ribs of the base body 11 are sometimes referred to as synthetic resin reinforcing ribs, which are disposed on the outer surface of the base body 11 to reduce the deflection and torsion of the base body 11 and / or the terminal block 10. A conventional terminal block has a non-resin reinforcing member, which may be a metal reinforcing plate at least partially embedded in the resin of the base body and extending radially outward from the base body. In contrast, the terminal block 10 of the embodiment does not have a non-resin reinforcing member that may be such a metal reinforcing plate. The ribs of the base body 11 can omit the non-resin reinforcing member that may be a metal reinforcing plate at least partially embedded in the resin of the base body.

[0118] The embodiments disclosed herein should be considered illustrative in all respects and not restrictive. The scope of the invention is shown not by the foregoing, but by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.
