The second fluid connector is used to engage the first fluid connector in a first direction to form a fluid channel. The second assembly includes a main body, a guide structure, and a cushioning resilient member. The fastening member is located on the main body. The guide structure is located on the main body, and the second fluid connector is fixed on the guide structure. The cushioning resilient member is connected to the guide structure to provide a buffer displacement of the second fluid connector along the second direction when the first and second fluid connectors are joined, wherein an included angle is formed between the second direction and the first direction. ## Claims ### Claim 1 A blind insert fluid connection module comprising: a first fluid connector disposed on a first assembly; and a second fluid connector disposed on a second assembly, the second fluid connector configured to engage the first fluid connector to form a fluid channel in a first direction, the second assembly comprising: a main body; a fastening member disposed on the main body; a guide structure disposed on the main body and having a rectangular profile, wherein the guide structure comprises arc-shaped buffer pieces for positioning the second fluid connector such that the second fluid connector is movably connected with the guide structure, wherein each arc-shaped buffer piece has two opposite ends connected to two immediately-adjacent corners of the rectangular profile of the guide structure; and a cushioning resilient member connected to the guide structure and configured to provide a buffer displacement of the second fluid connector in a second direction when the first and second fluid connectors are joined, wherein an included angle is formed between the second direction and the first direction. ### Claim 2 (depends on 1) The blind insert fluid connection module of claim 1, wherein the cushioning resilient member has a spiral spring surrounding the second fluid connector and in contact with the fastening member. ### Claim 3 (depends on 2) The blind insert fluid connection module of claim 2 further comprising a fluid tube coupled to the second fluid connector. ### Claim 4 (depends on 1) The blind insert fluid connection module of claim 1, wherein the first assembly is a server rack, the second assembly is a server computing unit. ### Claim 5 A blind insert fluid connection module comprising: a first fluid connector disposed on a first assembly; and a second fluid connector disposed on a second assembly, the second fluid connector configured to engage the first fluid connector to form a fluid channel, the second assembly comprising: a main body; a guide structure disposed on the main body and comprising arc-shaped buffer pieces to define a passage through which the second fluid connector passes, wherein the guide structure has a rectangular profile, each arc-shaped buffer piece has two opposite ends connected to two immediately-adjacent corners of the rectangular profile; and a cushioning resilient member being in physical contact with at least one of the arc-shaped buffer pieces. ### Claim 6 (depends on 5) The blind insert fluid connection module of claim 5, wherein each arc-shaped buffer piece has a concave side facing a corresponding edge of the rectangular profile. ### Claim 7 (depends on 5) The blind insert fluid connection module of claim 5 further comprising a fluid tube coupled to the second fluid connector. ### Claim 8 (depends on 7) The blind insert fluid connection module of claim 7, further comprising a fastening member disposed on the main body and having an opening, wherein the fluid tube is coupled to the second fluid connector through the opening. ### Claim 9 (depends on 5) The blind insert fluid connection module of claim 5, wherein convex sides of the arc-shaped buffer pieces collectively define the passage through which the second fluid connector passes. ### Claim 10 A blind insert fluid connection module comprising: a first fluid connector disposed on a first assembly; and a second fluid connector disposed on a second assembly, the second fluid connector configured to engage the first fluid connector to form a fluid channel, the second assembly comprising: a main body; a guide structure disposed on the main body, wherein the guide structure comprises arc-shaped buffer pieces for positioning the second fluid connector, wherein the guide structure has a rectangular profile, each arc-shaped buffer piece has two opposite ends connected to two immediately-adjacent corners of the rectangular profile; and a spiral spring surrounding a circumference of the second fluid connector and connected to at least one of the arc-shaped buffer pieces. ### Claim 11 (depends on 10) The blind insert fluid connection module of claim 10, wherein the spiral spring is disposed between the circumference of the second fluid connector and the arc-shaped buffer pieces. ### Claim 12 (depends on 10) The blind insert fluid connection module of claim 10, wherein the spiral spring is connected to a convex side of at least one of the arc-shaped buffer pieces. ### Claim 13 (depends on 10) The blind insert fluid connection module of claim 10, wherein each arc-shaped buffer piece has a concave side facing a corresponding edge of the rectangular profile.
