Technical Field

The application relates to the technical field of equipment interconnection, in particular to a plug-in structure and an equipment interconnection system.

Background

In the equipment interconnection system, the equipment is mechanically connected with the equipment to realize the position fixation of the equipment, and the conduction of electricity, signals or refrigerants is realized by electric connection, signal connection or refrigerant connection. In order to improve the connection efficiency between the equipment, when the two pieces of equipment are aligned to realize mechanical connection, the inserting structures on the two pieces of equipment are matched and inserted to realize electric connection, signal or refrigerant conduction, so that the connection times between the equipment are reduced, and the connection efficiency is improved. However, the installation position of the plug structure on the device inevitably has a deviation, so when two devices are aligned to realize mechanical connection, the plug structures on the two devices cannot be aligned accurately, resulting in low matching reliability between the plug structures of the two devices (for example, electrical connection performance is reduced, signal contact is poor, a refrigerant cannot be conducted or leaked, etc.).

Fig. 1 and 2 illustrate an equipment interconnection system applied to a data center in the prior art, as shown in fig. 1 and 2, which includes a cabinet 01, a functional module (e.g., a server, a switch, and a memory) 02, a first plug-in structure 03 (shown in fig. 3), a second plug-in structure 04 (shown in fig. 4), a buckle 05, and a card slot 06; the cabinet 01 is enclosed into a slot 011; the functional module 02 is plugged into the slot 011; the buckle 05 is arranged at the rear end of the functional module 02 along the self-plugging direction, the slot 06 is arranged on the surface of the cabinet where the opening of the slot 011 is positioned, and the buckle 05 is clamped in the slot 06; the first plug-in structure 03 and the second plug-in structure 04 are plug-in structures, and the first plug-in structure 03 and the second plug-in structure 04 can be an electrical plug-in structure, a signal plug-in structure or a refrigerant plug-in structure, as shown in fig. 3, the first plug-in structure 03 is arranged on the bottom wall of the slot 011, and the plug-in direction of the first plug-in structure 03 is consistent with the plug-in direction of the slot 011; as shown in fig. 4, the second plug-in structure 04 is disposed at the front end of the functional module 02 along the plug-in direction of the functional module 02, and the plug-in direction of the second plug-in structure 04 is consistent with the plug-in direction of the functional module 02, and when the functional module 02 is plugged into the slot 011 and the buckle 05 is connected in the slot 06, the second plug-in structure 04 is plugged into the first plug-in structure 03, so that the connection frequency between the cabinet 01 and the functional module 02 is reduced, and the connection efficiency is improved. However, because there is inevitably a deviation between the installation position of the first plug structure 03 on the cabinet 01 and the installation position of the second plug structure 04 on the functional module 02, when the functional module 02 is plugged into the slot 011 enclosed by the cabinet 01, the first plug structure 03 and the second plug structure 04 cannot be aligned accurately, resulting in lower reliability of the first plug structure 03 and the second plug structure 04 in matching.

In some cases, a relative positional error between the first plug structure 12 and the second plug structure 22 exists not only in a plane perpendicular to the plugging direction of the first plug structure 12 but also in the plugging direction along the first plug structure 12. For example, as shown in fig. 6, when the second device 21 is plugged into the slot 111 defined by the first device 11, in order to ensure the aesthetic property of the device interconnection system, the rear end surface a of the second device 21 along the plugging direction should be flush with the surface b of the first device 11 where the opening of the slot 111 is located, so that a relative position error inevitably exists between the front end surface c of the second device 21 along the plugging direction and the bottom surface d of the slot 111, that is, a relative position error exists between the first plugging structure 12 and the second plugging structure 22 along the plugging direction (i.e., the direction x) of the first plugging structure 12.

In order to avoid the above problem, as shown in fig. 9, the diameter of the second connecting shaft section 1031b is smaller than the diameter of the second connecting hole 112, the second connecting shaft section 1031b can move relative to the first device along the radial direction of the second connecting hole 112, and the fixing base 101 can move relative to the first device 11 in the plane perpendicular to the plugging direction of the plugging member 102. The length of the first connecting shaft section 1031a is greater than that of the first connecting hole 1011, and the fixing seat 101 can slide along the first connecting shaft section 1031a in a direction away from the second connecting shaft section 1031 b; the connecting structure 103 further comprises an elastic component 1034, the elastic component 1034 is connected to the fixed seat 101, and the elastic component 1034 is configured to apply an elastic force to the fixed seat 101, which is directed to the second connecting shaft section 1031b along the length direction of the first connecting shaft section 1031a when the fixed seat 101 slides along the first connecting shaft section 1031a in a direction away from the second connecting shaft section 1031 b. In this way, the fixing base 101 can drive the insertion component 102 to move in the insertion direction of the insertion component 102, so as to compensate for a relative position error between the insertion structure 100 and the insertion structure 200 in the insertion direction along the insertion structure 100, and improve the matching reliability between the insertion structure 100 and the insertion structure 200.

The elastic component 1034 includes, but is not limited to, a compression spring and an extension spring, in some embodiments, as shown in fig. 9, the elastic component 1034 is a compression spring, the compression spring is sleeved on the first connecting shaft section 1031a, and the compression spring is located between the first stopping structure 1032 and the fixing base 101, one end of the compression spring close to the fixing base 101 abuts against a surface of the fixing base 101 facing the first stopping structure 1032, and one end of the compression spring close to the first stopping structure 1032 abuts against a surface of the first stopping structure 1032 facing the fixing base 101. When the first plug structure 12 and the second plug structure 22 have a relative position error in the plugging direction of the first plug structure 12, during the process of mating and plugging the first plug structure 12 and the second plug structure 22, the plug part 202 applies a pressing force directed to the rear end of the plug part 102 to drive the fixing base 101 to slide along the first connecting shaft section 1031a in the direction away from the second connecting shaft section 1031b, and during the process of sliding the fixing base 101 in the direction away from the second connecting shaft section 1031b, the compression spring is pressed to generate a compression deformation so as to compensate the relative position error of the first plug structure 12 and the second plug structure 22 in the plugging direction of the first plug structure 12. Meanwhile, the compressed compression spring can apply an elastic force to the fixing base 101, the elastic force being directed to the second connecting shaft section 1031b along the length direction of the first connecting shaft section 1031a, and the elastic force can drive the plugging part 102 to be tightly plugged with the plugging part 202, so as to improve the plugging reliability between the plugging part 102 and the plugging part 202.

In some embodiments, as shown in fig. 11, the first connecting shaft section 1031a and the second connecting shaft section 1031b are directly connected, so that the connecting shaft 1031 can be manufactured into an optical axis, the optical axis has a simple structure and a low processing cost, and the manufacturing cost of the connecting shaft 1031 can be reduced.

This third connecting shaft section can be molded when molding the first connecting shaft section 1031a and the second connecting shaft section 1031b, and thus is easily realized.
