Description

Technical Field

[0001] The utility model relates to the technical field of cable accessories, and particularly relates to a cable connection socket. Background Art

[0002] The "high-speed flying train" is a new type of transportation vehicle under research and development. It combines supersonic flight technology and rail transit technology, and uses superconducting magnetic levitation technology and vacuum pipelines to achieve supersonic "near-earth flight". The designed maximum speed of this train can reach 4,000 kilometers per hour, which is much faster than the speeds of existing high-speed rails and civil airliners. Due to the extremely high operating speed of the high-speed flying train, during its operation, the environment will become a low and medium altitude state and strong vibrations will occur, which puts higher requirements on the structure of the high-voltage connectors on the high-speed flying train. Therefore, the present application aims to provide a cable connection socket, which is a component in the high-voltage connector. When connected to other components, this connection socket can be stably connected and is not prone to loosening under high-frequency vibrations, and is suitable for use in high-speed flying trains.

[0005] Further, the outer surface of the protrusion on the flange insert is set as an uneven curved surface for increasing the connection strength between the flange insert and the insulating member.

[0006] Further, through grooves are provided on the protrusion. Preferably, there are multiple through grooves, and they are evenly distributed in a circle on the protrusion.

[0007] Further, both the first connection head and the second connection head are cylindrical, and cavities are provided inside. The cavities are used to contact with other connectors to achieve conductive connection.

[0009] Further, the inside of the first connection head is set as a stepped hole.

[0010] Furthermore, through holes are provided on the side wall of the first connector head. The through holes have the same function as the through grooves and can both increase the connection strength with the insulating member.

[0011] Furthermore, bolt holes are provided on the base of the flange insert for tightly connecting the socket with other components in cooperation with bolts.

[0012] Furthermore, the insulating member can be selected from materials such as epoxy resin insulating glue, polyvinyl chloride (PVC) insulating glue, and silicone rubber insulating glue.

The flange insert 1 includes a base 11, a central hole is provided in the middle of the base 11, and a ring of protrusions 12 is arranged around the central hole on one side of the base 11; the contact socket insert 2 is used for conducting electricity, and the contact socket insert 2 includes a connecting rod 21, and a first connector 22 and a second connector 23 are respectively arranged at both ends of the connecting rod 21, and the first connector 22 is arranged close to the flange insert 1; the insulating member 3 integrally casts the flange insert 1 and the contact socket insert 2.

[0024] In this embodiment, the outer surface of the protrusion 12 on the flange insert 1 is set as an uneven curved surface, which is used to increase the connection strength between the flange insert 1 and the insulating member 3. A through groove 13 is provided on the protrusion 12. There are 3 through grooves 13, and they are evenly distributed in a circle on the protrusion 12. The base 11 of the flange insert 1 is rectangular, and bolt holes 14 are also provided at the four corners of the rectangle. The bolt holes 14 are used to cooperate with bolts to tightly connect the socket with other related components.

[0025] In this embodiment, both the first connector 22 and the second connector 23 are cylindrical, and cavities are provided inside. The cavities are used to contact other connectors to achieve electrical connection. For example, the pins of some connectors can be inserted into the cavity of the first connector 22. The diameter of the first connector 22 is larger than that of the second connector 23, and the diameter of the second connector 23 is larger than that of the connecting rod 21. The internal cavity of the first connector 22 is set as a stepped hole.
