Flip each one open.

During the opening process, since the first housing 101 and the second housing 201 are both separated from both sides of the third housing 301, when the first housing 101 and the third housing 301 are separated, they will be pulled apart. The spacing between them makes the first terminal 102 stay away from the winding drum 304b of the winding member 304 on the side of the first housing 101, thereby stretching the cable 305 wound on the winding drum 304b at this end. The cable 305 will move outward along the limiting clamping ring 304e, and will also drive the winding drum 304b to rotate, so that the winding drum 304b drives the spring 304c to tighten on the intermediate drum 304a, so that the cable 305 automatically Adapt the distance between the first housing 101 and the third housing 301.

The limiting clamping ring 304e moves outward and also drives the winding drum 304b to rotate, so that the winding drum 304b drives the spring 304c to tighten on the intermediate drum 304a, so that the cable 305 self-adapts to the second housing. 201 and the third housing 301.

When the arrangement sequence of the wire cores needs to be adjusted, since the male end component 100 is defined by China Southern Power Grid, the female end component 200 needs to be connected to other aviation wires, so it is necessary to adjust the cable according to the rules of the two parties regarding the arrangement of the wire cores. 305 is re-plugged and unplugged so that the two wire cores have the same function.

When the wire core is internally aged due to frequent stretching or long-term use and needs to be replaced, the two ends of the cable 305 are pulled out from the first terminal 102 and the second terminal 202 and connected internally. Under the action of the spring 304c, the two winding drums 304b rotate on the intermediate drum 304a, thereby winding both ends of the cable 305, and all the cables 305 are wound on the winding member 304, and then the The rewinding member 304 is removed from the mounting hole 306a of the mounting plate. During disassembly, press the pressing rod 303l to descend. The descending of the pressing rod 303l drives the lock block 303j and the piston rod 303e to descend.
