Description

Technical Field

[0001] The utility model belongs to the technical field of cable connection, in particular to an underwater cable pulling-off structure. Background Art

[0002] At present, the common underwater transmission is the interconnection of connectors, plug connectors and socket connectors, and the socket connector is fixed on the equipment panel. With the different application objects and application environments, there are more and more connection methods. For these, the installation space or operation space is relatively limited, and the socket connector cannot be installed normally. Therefore, the demand for a plug-in connection structure for underwater cables is increasing.

[0003] The plug connector includes a male plug and a female plug. When the staff plug the male plug and the female plug into each other, they are easily separated from each other under the action of external force, thus affecting the normal use of the power supply system.

[0004] The patent with publication number CN 216055452 U discloses a plug-in connection structure for underwater cables, which belongs to the field of cable connection technology, and includes a male plug and a female plug, wherein the male plug is plugged with the female plug, and one end of the male plug facing the female plug is fixedly connected with a mounting shell, and a clamping mechanism is symmetrically arranged on the inner wall of the mounting shell. Through the clamping of the clamping block and the clamping groove, the male plug and the female plug are prevented from falling off after being connected, and the clamping block is tightened by the cooperation of the tightening spring and the limit plate, and the clamping block is conveniently controlled by the pulling and pulling of the movable rod, which facilitates the disassembly of the male plug and the female plug, and the stability of the connection between the male plug and the female plug is ensured by the adaptive sliding of the sliding block and the sliding groove. By setting the clamping block as a right-angled triangle structure with an arc-shaped hypotenuse, it is convenient to make the movable rod move under the action of the limit plate when the sliding block contacts the clamping block, so as to facilitate the quick connection of the male plug and the female plug.

[0005] However, when removing the device, two movable rods need to be pulled to move the card block away from the card slot. The process requires two hands to operate, and the convenience is average. Utility Model Content
