[0027] The prior art TW201913281A provides a bus bar assembly for electrically connecting servers in a server rack to an external bus bar so that power can be supplied from the external bus bar to the internal components of the servers through the bus bar assembly. However, during the transportation of the server rack, the bus bar assembly is prone to damage due to collisions.

[0028] The present utility model proposes a bus bar module, aiming to improve the heat dissipation effect of the bus bar module.

[0029] Please refer to Figure 1 , Figure 1 , which is a schematic structural diagram of an embodiment of the bus bar module provided by the present utility model. The bus bar module 100 can be applied to electrically connect servers in a server rack (not shown) so as to supply power to the servers. As Figure 1 shown, the bus bar module 100 includes an upper bus bar plate 110, a lower bus bar plate 120, and two connector assemblies 130. The upper bus bar plate 110 is stacked on top of the lower bus bar plate 120, and an insulating layer is sandwiched between the upper bus bar plate 110 and the lower bus bar plate 120 to electrically insulate the upper bus bar plate 110 and the lower bus bar plate 120. Specifically, the upper bus bar plate 110 includes a first horizontal plate 111. The lower bus bar plate 120 includes a second horizontal plate 121. The second horizontal plate 121 is parallel to the first horizontal plate 111. The insulating layer is sandwiched between the first horizontal plate 111 and the second horizontal plate 121.

[0030] As Figure 1As shown, each of the two connector components 130 is electrically connected to the upper bus bar plate 110 and the lower bus bar plate 120. Specifically, the two connector components 130 are arranged vertically. The first horizontal plate 111 includes a first coupling portion 111a extending to one side of the two connector components 130. The second horizontal plate 121 includes a second coupling portion 121a extending to the other side of the two connector components 130. The upper connector component 130 is connected to the upper surfaces of the first coupling portion 111a and the second coupling portion 121a, and the lower connector component 130 is connected to the lower surfaces of the first coupling portion 111a and the second coupling portion 121a.

[0031] In other embodiments, the bus bar module 100 may include only one connector component 130.

[0032] As Figure 1 shown, the bus bar module 100 further includes two liquid cooling tubes 150. Each liquid cooling tube 150 has a liquid inlet connector 151 and a liquid outlet connector 152. At least a portion of the two liquid cooling tubes 150 is respectively embedded in the first horizontal plate 111 and the second horizontal plate 121. Specifically, the surface of the first horizontal plate 111 away from the second horizontal plate 121 has a groove 111b, and one of the liquid cooling tubes 150 is embedded in the groove 111b. Similarly, the surface of the second horizontal plate 121 away from the first horizontal plate 111 has a groove 121b, and the other liquid cooling tube 150 is embedded in the groove 121b.

[0033] In some embodiments, as Figure 1 shown, the top surface and the bottom surface of the liquid cooling tube 150 are both flat surfaces.

[0034] Furthermore, the height of the liquid cooling tube 150 is about 100% to 200% of the depth of the grooves 111b and 121b, which means that most of the liquid cooling tube 150 may be embedded in the grooves 111b, 121b to control its height.

[0035] As Figure 1 shown, the first horizontal plate 111 and the second horizontal plate 121 also each include a pair of overlapping protrusions 111c. The protrusions 111c horizontally extend from the edges of the main body portions of the first horizontal plate 111 and the second horizontal plate 121 respectively.

[0036] As Figure 1As shown, the first horizontal plate 111 and the second horizontal plate 121 each have two pairs of fixing holes 111. Each fixing hole 111 of the first horizontal plate 111 is aligned with the corresponding fixing hole 111 of the second horizontal plate 121, and each fixing hole 111 is a through hole. One hole in one pair of fixing holes 111 is located on the protruding portion 111c, and the other is located on the main body portion beside it. The liquid cooling pipe 150 embedded in the first horizontal plate 111 turns and passes through the area between the two pairs of fixing holes 111.

[0037] See Figure 2 . Figure 2 FIG. is a schematic structural diagram of an embodiment of a connector assembly provided by the present utility model, in which the housing 132c of the electrical connector 132 is removed. As Figure 2 shown, in this embodiment, the connector assembly 130 includes an electrical connector 132 and two adapters 131 (i.e., Figure 1 the two connector assemblies 130 in include four adapters 131). The electrical connector 132 includes a plurality of positive terminals 132a and a plurality of negative terminals 132b. The two adapters 131 extend away from each other and are symmetric with respect to the electrical connector 132. Each adapter 131 includes a vertical plate 131a, a fixing plate 131b, and an arc-shaped arm 131c connected between the vertical plate 131a and the fixing plate 131b. The vertical plate 131a and the fixing plate 131b of one adapter 131 (i.e., Figure 2 the right adapter 131 in) are respectively connected to the positive terminal 132a and the first coupling portion 111a of the first horizontal plate 111. The vertical plate 131a and the fixing plate 131b of the other adapter 131 (i.e., Figure 2 the left adapter 131 in) are respectively connected to the negative terminal 132b and the second coupling portion 121a of the second horizontal plate 121.

[0038] See Figure 3 . Figure 3 FIG. is a top view of an embodiment of the adapter in the connector assembly provided by the present utility model. As Figure 3 shown, the adapter 131 further includes a bending portion 131d connected between the arc-shaped arm 131c and the vertical plate 131a. The width W2 of the fixing plate 131b is smaller than the width W1 of the bending portion 131d. The bending portion 131d with a larger width W1 helps the power transmission of the adapter 131. Specifically, the vertical plate 131a, the bending portion 131d, the arc-shaped arm 131c, and the fixing plate 131b are arranged in sequence in a transverse direction, and the width W1 of the bending portion 131d and the width W2 of the fixing plate 131b are measured in another transverse direction perpendicular to this transverse direction.

[0039] In some embodiments, the width W1 of the bending portion 131d is less than about 1.3 times the width W2 of the fixing plate 131b. In some embodiments, the width W1 of the bending portion 131d is greater than about 1.1 times the width W2 of the fixing plate 131b. In a specific example, the width W1 of the bending portion 131d is about 28.6 mm, and the width W2 of the fixing plate 131b is about 24.1 mm.

[0040] As Figure 3 shown, the width W1 of the bending portion 131d is less than the width W3 of the vertical plate 131a.

[0041] In some embodiments, the width W1 of the bending portion 131d is less than about 0.4 times the width W3 of the vertical plate 131a. In some embodiments, the width W1 of the bending portion 131d is greater than about 0.25 times the width W3 of the vertical plate 131a. In a specific example, the width W1 of the bending portion 131d is about 28.6 mm, and the width W3 of the vertical plate 131a is about 66.5 mm.

[0042] As Figure 3 shown, the width of the arc-shaped arm 131c increases from the fixing plate 131b to the bending portion 131d. That is, the width of the arc-shaped arm 131c increases from W2 to W1. Specifically, the arc-shaped arm 131c includes a first portion 131c1 and a second portion 131c2, which are connected to each other and are respectively connected to the fixing plate 131b and the bending portion 131d. The width of the first portion 131c1 increases from the fixing plate 131b to the second portion 131c2. The second portion 131c2 has a uniform width, which is greater than the width of the first portion 131c1. As Figure 3 shown, the uniform width of the second portion 131c2 is equal to the width W1 of the bending portion 131d. The width of the end of the first portion 131c1 connected to the fixing plate 131b is equal to the width W2 of the fixing plate 131b. In other words, the width of the first portion 131c1 increases from the fixing plate 131b to the second portion 131c2, increasing from the width W2 to the width W1. As Figure 3 shown, the connection between the first portion 131c1 and the second portion 131c2 is substantially located in the middle of the arc-shaped arm 131c.

[0043] As Figure 3 shown, the edge of the first portion 131c1 on one side (i.e., the left side) of the arc-shaped arm 131c is straight, while the edge of the first portion 131c1 on the other side (i.e., the right side) of the arc-shaped arm 131c is curved.

[0044] See Figure 4 . Figure 4 This is a partial side view of an embodiment of the adapter 131 in the connector assembly provided by the present utility model. As Figure 4As shown, the arcuate arm 131 has a highest point HP relative to the fixed plate 131b. The first part 131c1 and the second part 131c2 of the arcuate arm 131c are substantially connected to each other at the highest point HP.

[0045] As Figure 4 shown, the first part 131c1 of the arcuate arm 131c includes a first concave arc portion 131c11 connected to the fixed plate 131b and a first convex arc portion 131c12 connected to the first concave arc portion 131c11. The second part 131c2 of the arcuate arm 131c includes a second convex arc portion 131c21 connected to the first part 131c1 and a second concave arc portion 131c22 connected to the second convex arc portion 131c21. That is, the first convex arc portion 131c12, the first concave arc portion 131c11, the second convex arc portion 131c21, and the second concave arc portion 131c22 are alternately bent forward and backward from the fixed plate 131b to the bending portion 131d.

[0046] As Figure 4 shown, the first concave arc portion 131c11 has a radius of curvature R1, the first convex arc portion 131c12 has a radius of curvature R2, the second convex arc portion 131c21 has a radius of curvature R3, and the second concave arc portion 131c22 has a radius of curvature R4. In this way, the first convex arc portion 131c12, the first concave arc portion 131c11, the second convex arc portion 131c21, and the second concave arc portion 131c22 are smoothly connected in sequence.

[0047] As Figure 4 shown, the radius of curvature R1 of the first concave arc portion 131c11 is smaller than the radius of curvature R2 of the first convex arc portion 131c12. The radius of curvature R4 of the second concave arc portion 131c22 is smaller than the radius of curvature R3 of the second convex arc portion 131c21.

[0048] In some embodiments, the radius of curvature R2 of the first convex arc portion 131c12 is more than three times greater than the radius of curvature R1 of the first concave arc portion 131c11. In some embodiments, the radius of curvature R3 of the second convex arc portion 131c21 is more than three times greater than the radius of curvature R4 of the second concave arc portion 131c22. In a specific example, the radius of curvature R2 of the first convex arc portion 131c12 and the radius of curvature R3 of the second convex arc portion 131c21 are approximately 13.6 mm, and the radius of curvature R1 of the first concave arc portion 131c11 and the radius of curvature R4 of the second concave arc portion 131c22 are in the range of approximately 3.5 mm to approximately 4.0 mm.

[0049] The above are only exemplary embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
