A connection system for fluid conduction having a male connection end (2), a female connection end (3) and a retaining element (4). The male connection end (2) having a retaining groove (21) which makes up a first recess (22). The female connection end (3) having a retaining hole (31) which makes up a second recess (32) facing the first recess (22). The retaining element (4) is designed to be inserted through the retaining hole (31) and be housed between the first recess (22) and the second recess (32) to keep the male connection end (2) attached to the female connection end (3) when both ends (2, 3) are connected. The connection system (1) has a gasket (5) placed between the male connection end (2) and the female connection end (3), configured to hinder relative movements of said ends (2, 3) when connected along an axial direction (X).

Underground drilling operation often requires connecting a drill tool (e.g., drill bit, backreamer, etc.) to a drill string. It is desirable to connect the drill tools to a drill string in a manner that facilitates quick and easy assembly and disassembly. Low torque coupling, commonly referred to as torque-less connection, can provide such functionality. The useful life and strength of such connections can be improved upon. The present disclosure provides a low torque coupling with improved strength and durability.

Methods, apparatuses, and systems for fluid connections in modular cooling systems for cooling electronic components installed in equipment racks. A cold plate is positioned adjacent to a support manifold in a mated position, where the cold plate comprises a plate connector. The plate connector comprises a plate outer sleeve and defines a central passageway. The support manifold comprises a manifold connector, which comprises a manifold outer sleeve and defines a central passageway. An outer surface of the manifold outer sleeve is positioned adjacent to an outer surface of the plate outer sleeve. A cam is rotated about a pivot pin and engages with a plate retainer to secure the cold plate against the support manifold, and the central passageway of the plate connector is connected in fluid communication with the central passageway of the manifold connector.

Technologies for modular cooling systems for cooling electronic components installed in equipment racks are provided herein. A modular cooling system comprises a cold plate and a support manifold connected to the cold plate. Together, the support manifold and cold plate define a fluid path for cooling fluid from the support manifold to the cold plate. The modular cooling system also includes an equipment carrier including equipment cooled by the cold plate.

A female fluid connector (2) for a quick connecting and disconnecting fluid coupling (1) includes a housing (4) with an axially arranged inner recess (5) for receiving a corresponding male connector (3) of the quick connecting and disconnecting fluid coupling (1); a latching pin (13) for reversible fixation of the male fluid connector (3) inside the female fluid connector (2) of the quick connecting and disconnecting fluid coupling (1) in a latching position (FIG. 2); and a guiding slot (12) that is provided in the housing (4) for guiding said latching pin (13) during a movement of the latching pin (13), wherein said guiding slot (12) is arranged at an angle () with respect to the axial direction (7). The angle () that is enclosed by the direction of the guiding slot (12) and the axial direction (7) is larger than 45.5, preferably larger than 46.
