Description

Connector with directional floating function and connector assembly Technical Field The invention belongs to the technical field of connectors, and particularly relates to a connector with a directional floating function and a connector assembly. Background The optical fiber plug connector and the socket connector are respectively arranged on the daughter board and the backboard in the data center equipment cabinet, so that blind plug connection between the daughter board and the backboard is realized, the connection density in the equipment cabinet is improved, the wiring space is saved, and the installation and maintenance are convenient. After the inter-board (between the daughter board and the back board) contacts are inserted and mated, the locking of the outer housing (i.e., the structural member) and the inner housing of the receptacle connector provided on the back board is achieved by the cooperation of the first locking hooks 3021 of the outer housing and the second locking hooks 3031 of the inner housing, as shown in fig. 49. The first locking hook 3021 and the second locking hook 3031 have complex structures and difficult assembly when the inner housing and the outer housing of the receptacle connector are assembled, and the hook-shaped structure is easy to generate fracture risk, so that long-term life stability is difficult to ensure. The hook-shaped structures of the inner shell and the outer shell of the socket connector are locked by deformation of the hook-shaped structures, the problems that the hook-shaped structures are easy to wear and break are required to be solved in long-term service, the hook-shaped structures are of cantilever structures, the first locking hooks 3021 abut against the second locking hooks 3031 to realize locking, when the socket connector floats, uncontrollable deformation of the first locking hooks 3021 and the second locking hooks 3031 is easy to occur, the locking state is unstable, and the floating direction is also deviated. The socket connector provides a supporting force through the floating spring which is limited between the outer shell and the inner shell by the locking structure (the first locking hook 3021 and the second locking hook 3031), so that the first locking hook 3021 is propped against the second locking hook 3031, an external force is applied to the socket connector, the elastic force of the floating spring is overcome, and the first locking hook can be separated from the second locking hook, so that the socket connector has certain locking and floating capabilities, as shown in fig. 48. The floating spring in the socket connector is arranged in an inner cavity formed after the outer shell and the inner shell are assembled, and the floating spring is easy to shake. The floating spring between the inner shell and the outer shell of the socket connector does not have an orientation function, so that the connector floats irregularly and cannot realize reliable butt joint, a new structure is designed to meet the orientation requirement, and the reliable butt joint of products is ensured. Disclosure of Invention In order to solve the technical problems that the locking structure of the connector is easy to damage and unreliable in butt joint, the invention provides a connector with a directional floating function and a connector assembly. The aim of the invention is realized by adopting the following technical scheme. The connector with the directional floating function comprises a socket shell and a socket structural member arranged on the outer side of the socket shell, wherein one of the socket shell and the connector structural member is provided with a limiting groove, the other one of the socket shell and the connector structural member is provided with a limiting projection, the limiting projection is axially and slidably embedded in the limiting groove, an elastic piece I capable of axially stretching and contracting is arranged between the socket shell and the socket structural member, and the limiting projection can be abutted in the limiting groove under the action of the axial elastic force of the elastic piece I. Compared with the prior art, the invention has the following advantages: the elastic piece I is arranged to axially stretch, so that deflection of the elastic piece I is avoided, and the socket shell and the socket structural member can be relatively fixed under the action of elastic force of the elastic piece I. Further, the front end of the limit bump is provided with a chamfer I. Compared with the prior art, the invention has the following advantages: through the chamfer I of spacing lug, when inserting socket structure spare on socket casing, can reduce the cartridge resistance, be convenient for assemble. Further, the socket structural member is provided with an axially extending guide post, the guide post is sleeved with an elastic piece I so that the elastic piece I stretches in the axial direction, the socket shell is
