The rib 43 has a shape that partially covers the second through hole 22 in the circumferential direction when viewed in the second direction D2. Also, the rib 43 has a shape along the periphery of the second through hole 22 when viewed in the second direction D2. Specifically, the rib 43 has a side surface 43a on the second through hole 22 side. The entire side surface 43a in the direction along the circumferential direction has an arc shape centered on the central axis line C2 of the second through hole 22 .

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 positioned between the two second through holes 22 . In the first portion 44, the side surface 43a of the rib 43 has an arcuate shape centered on the central axis C2. The rib 42 is located between the first portions 44 of the ribs 43 in the third direction D3.

The second portion 45 of the rib 43 is positioned inside the second through hole 22 in the first direction D1. The second portion 45 has a shape that covers the inside of the second through hole 22 in the first direction D1 as viewed in the second direction D2.

A side surface of the second portion 45 on the side of the second through hole 22 is configured as a separation surface 46 . The spacing surface 46 has, for example, a planar shape perpendicular to the first direction D1. That is, the separation surface 46 is a surface extending along the third direction D3 when viewed in the second direction D2. The second portion 45 and its separation surface 46 extend, for example, to the outer edge of the second fixing portion 17 in the third direction D3. Here, a straight line perpendicular to the central axis C2 of the second through hole 22 and along the first direction D1 is defined as a reference line L2. Outside the second through-hole 22 in the third direction D3, the separation surface 46 is spaced apart from the second through-hole 22 as it separates from the reference line L2 along the third direction D3. That is, the distance between the second through hole 22 and the second portion 45 widens toward the outside of the second through hole 22 in the third direction D3.

On the upper surface 17a side of the second fixing portion 17, the outside of the second through hole 22 in the first direction D1 is open. That is, no rib facing the second portion 45 of the rib 43 in the first direction D1 is provided outside the second through hole 22 in the first direction D1.

As described above, the second rib group 41 is provided between the two second through holes 22 . In this embodiment, the number of ribs of the second rib group 41 provided on the second end portion 15 is three in total, one rib 42 and two ribs 43 . That is, the base body 11 is configured such that the number of ribs in the first rib group 31 is greater than the number of ribs in the second rib group 41 .

The operation of this embodiment will be described.
As shown in FIG. 5 , the side of the distal end surface of the projecting portion 61 in the third direction D3 is covered with the projecting wall portion 54 . Therefore, the protruding wall portion 54 can prevent the tip end face of the protruding portion 61 from being exposed to water.

Effects of the present embodiment will be described.
(1) The table body 11 has a protruding wall portion 54 protruding from the first surface 11a at a position outside the seal member 37 . According to this configuration, it is possible to prevent water from entering between the first surface 11a of the table main body 11 and the device M by the projecting wall portion 54 . This can prevent water from reaching the seal member 37 , and as a result, it is possible to more reliably prevent the first connection portion 51 from being exposed to water.

(2) The protruding amount of the protruding wall portion 54 from the first surface 11a is larger than the protruding amount of the sealing member 37 from the first surface 11a. According to this configuration, it is possible to more preferably suppress water from entering between the first surface 11 a of the table main body 11 and the device M by the projecting wall portion 54 .

(3) The projecting wall portion 54 is provided at the edge of the first surface 11a. According to this configuration, it is possible to prevent water from entering between the first surface 11 a and the device M at the edge of the first surface 11 a of the table body 11 .

(4) The projecting wall portion 54 has an inner wall surface 55 . The inner wall surface 55 faces the first connecting portion 51 side. According to this configuration, it is possible to more preferably suppress water from entering between the first surface 11 a of the table main body 11 and the device M by the projecting wall portion 54 .

(5) A plurality of terminals 12 are arranged side by side in a first direction D1 that intersects the projecting direction of projecting wall portion 54 . The projecting wall portion 54 extends along the first direction D1. According to this configuration, the base body 11 tends to be long in the first direction D1 in which the terminals 12 are arranged. In this case, the base body 11 can be easily bent in a direction perpendicular to the longitudinal direction. In this respect, according to the above configuration, the protruding wall portion 54 extends along the longitudinal direction of the table body 11, so that the protruding wall portion 54 serves as reinforcement for the table body 11, and the table body 11 extends in the longitudinal direction. The projecting wall portion 54 can suppress bending in the orthogonal direction.

An inner wall surface 55 of the projecting wall portion 54 is inclined away from the first connection portion 51 toward the tip of the projecting wall portion 54 . Thereby, the space on the side of the first connecting portion 51 with respect to the projecting wall portion 54 can be widened. In addition, due to the inclination of the inner wall surface 55, the protruding wall portion 54 has a shape in which the thickness becomes thinner toward the tip side. As a result, removal of the mold for forming the terminal block 10 in the first direction D1 is facilitated.

(6) In the first direction D1, the range A1 in which the projecting wall portion 54 is provided includes the range A2 in which the seal member 37 is arranged. According to this configuration, the projecting wall portion 54 can cover a wider range than the sealing member 37 in the first direction D1. Therefore, the projecting wall portion 54 can more reliably prevent water from reaching the seal member 37 .

(7) The projecting wall portions 54 are provided on both sides of the first connecting portion 51 in the direction along the first surface 11a. According to this configuration, the pair of protruding wall portions 54 can prevent water from reaching the seal member 37 on both sides of the seal member 37 .

(8) The base body 11 has an opening 13a provided on the second surface 11b. And the 1st connection part 51 is exposed from the base main body 11 through the opening part 13a while being accommodated inside the opening part 13a. According to this configuration, since the first connection portion 51 is arranged inside the opening portion 13a, the first connection portion 51 can be protected.

(9) The terminal block unit U includes the terminal block 10 and the equipment M to which the terminal block 10 is attached. The device M has a protruding portion 61 protruding toward the terminal block 10, a device-side opening 62 provided in the protruding portion 61, and a first mating terminal T1. The first connection portion 51 is inserted through the device-side opening 62 . The first connection portion 51 and the first mating terminal T1 are connected through the device-side opening 62 . The sealing member 37 of the terminal block 10 is in contact with the periphery of the device-side opening 62 of the projecting portion 61 . According to this configuration, the device M has the projecting portion 61 that contacts the seal member 37 of the terminal block 10 . As a result, the sealing member 37 can be brought into contact with the device M without causing the projecting wall portion 54 of the terminal block 10 to interfere with the device M.

(10) The terminal block 10 is used with the base body 11 tilted such that the first end 14 is located below the second end 15 in the first direction D1. The second end portion 15 of the base body 11 is provided with a second through hole 22 penetrating along the second direction D2. The base body 11 has a rib 43 that extends in the second direction D2 and has a shape that covers the first end portion 14 side of the second through hole 22 as viewed in the second direction D2. A straight line perpendicular to the central axis C2 of the second through hole 22 and along the first direction D1 is defined as a reference line L2, and the side surface 43a of the rib 43 on the side of the second through hole 22 increases with distance from the reference line L2. A spacing surface 46 spaced apart from the second through hole 22 is included.

According to this configuration, the gap between the bolt attached to the second through hole 22 and the separation surface 46 of the rib 43 can be configured to widen as the distance from the reference line L2 increases. As a result, the separation surface 46 facilitates drainage of water that has entered the gap between the bolt and the rib 43 . Therefore, it is possible to suppress corrosion of the bolts mounted in the second through holes 22 located upstream of the inclination of the table body 11 .

(11) The entire side surface 33a of the rib 33 on the side of the first through hole 21 is arcuate around the central axis C1 of the first through hole 21 . According to this configuration, at the first end portion 14 located on the downstream side of the inclination of the table main body 11 , water is less likely to accumulate between the bolts attached to the first through holes 21 and the ribs 33 . For this reason, in the rib 33, the entire side surface 33a of the rib 33 is arc-shaped around the central axis C1 of the first through hole 21 without providing the separation surface 46 like the rib 43, thereby The strength around the 1-through hole 21 can be preferably improved.

(12) In the base body 11, the second part 35 side in the first direction D1 with respect to the first through hole 21 is defined as the inner side, and the opposite side is defined as the outer side in the first direction D1. is not provided with a rib that faces the second portion 35 in the first direction D1. According to this configuration, no rib facing the second portion 35 in the first direction D1 is provided outside the first through hole 21 in the first direction D1. Thereby, in the first end portion 14, the water adhering around the first through hole 21 can be easily drained outward in the first direction D1. Therefore, it is possible to suppress corrosion of the bolts mounted in the first through holes 21 .

(13) A plurality of terminals 12 are provided side by side along the first direction D1. According to this configuration, the terminal block 10 having the plurality of terminals 12 can be shortened in the third direction D3.

(14) The first end 14 has a bottom wall 14a with an upper surface. The bottom wall 14a has a drainage part 36 whose upper surface is displaced downward from the second end 15 side toward the first end 14 side. According to this configuration, the drainage part 36 can suitably drain the water adhering to the upper surface of the first end 14 toward the outer edge of the first end 14 in the first direction D1.

(15) The upper surface of the drainage part 36 has a stepped shape that displaces downward from the second end 15 side toward the first end 14 side. With this configuration, it is possible to improve the ease with which the mold can be pulled out when molding the base body 11 . As a result, it can contribute to the improvement of the moldability of the base body 11 .

(16) A recess 38 to which a seal member 37 is attached is provided on the lower surface of the bottom wall 14a. The outer edge of the recess 38 is provided on the lower surface of the bottom wall 14a at a position that does not straddle the step of the drainage section 36. As shown in FIG. According to this configuration, the lower surface of the bottom wall 14a having the recess 38 can be shaped to follow the stepped shape of the upper surface of the drainage portion 36. As shown in FIG. Therefore, the thickness of the bottom wall 14a can be made as uniform as possible. As a result, in the bottom wall 14a, it is possible to suppress deformation such as sink marks that may occur due to variations in plate thickness.

(17) Two first through holes 21 are provided side by side in a direction perpendicular to the second direction D2 and crossing the first direction D1. The base body 11 has a rib 32 provided between the two first through holes 21 and extending in the second direction D2. The rib 32 has a shape extending along the first direction D1 when viewed in the second direction D2. With this configuration, the strength of the first end portion 14 can be improved more favorably. Further, the ribs 32 can function as guides for draining water adhering to the upper surface of the first end portion 14 toward the outer edge of the first end portion 14 in the first direction D1.

(18) In the base body 11, the number of ribs in the first rib group 31 provided at the first end portion 14 on the lower side of the slope is the same as the number of ribs provided on the second end portion 15 on the upper side of the slope. It is greater than the number of ribs in the rib group 41 . According to this configuration, the strength of the first end portion 14 to which a particular load is applied due to the inclined posture of the table body 11 can be effectively improved by the first rib group 31 having a large number of ribs. As a result, deformation of the first end portion 14 can be effectively suppressed.
