Similarly, the lower base 51 of the lower latch lever 5 forms a lever, and when the lower free end 52 of the lower latch lever 5 is pressed upward, the lower ejection post 53 is ejected downward, so that the outer clip 23 is released from the lower clip groove 36. Meanwhile, an inner clamping groove 34 is formed in the lower clamping handle 5, the inner clamping groove 34 is arranged on one side close to the lower top column 53, and the clamping opening is arranged upwards, so that the inner clamping groove 34 and the inner clamping buckle 24 are loosened along with the downward movement of the lower top column 53.

Further, the inner clip 24 includes a body and a protruding end 241, the protruding end 241 is formed with a guide surface, the inner clip 34 includes a groove body and an elastic block 341 disposed outside the groove body, and one surface of the elastic block 341 facing the protruding end 241 is an inclined surface. The provision of the guide surface at the protruding end 241 and the provision of the inclined surface at the elastic block 341 are for the purpose of facilitating the sliding of the protruding end 241 into the inner catching groove 34.

Further, the lower support pillar 53 includes two support rods arranged at intervals, the elastic block 341 is arranged between the two support rods, and two side surfaces of the elastic block 341 are respectively connected with the two support rods, so that the elastic block 341 can move along with the movement of the two support rods. This design allows the elastic block 341 to move together with the lower post 53. Thereby facilitating separation of inner catch 34 from inner catch 24.

Synthesize above-mentioned embodiment, when needs separation male end 2 and female end 3, only need press simultaneously and press card handle 4 and lower card handle 5, specifically, go up card handle 4 and press down, lower card handle 5 upwards presses, can be in order to realize outer buckle 23 and outer draw-in groove (including last draw-in groove 35 and lower draw-in groove 36), interior buckle 24 and interior draw-in groove 34 separation simultaneously. One of the innovations of the present invention is also the design of the push rod 44, when the upper latch handle 4 is pressed down, the push rod 44 gives an outward pushing force to the male housing 22, so that the male end 2 is separated from the female end 3 under the pushing force. Like this, after pressing card handle 4 and lower card handle 5, need not to add the power of pulling out again, can part public end 2 and female end 3, convenient dismantlement has solved the separating force that traditional pencil plug-in components need big to at the difficult technical problem of operation in narrow and small space. The male end 2 can also be set to be in an asymmetric shape, so that the mistake and fool proofing effects are achieved.

Further, the plug connector also comprises a rotation limiting part arranged on the female shell, the rotation limiting part comprises a rotating rod 62, knobs 61 arranged at two ends of the rotating rod 62 and a limiting boss 63 arranged on the rotating rod 62, the limiting boss 63 is used for limiting the movement of the upper clamping handle 4 and the lower clamping handle 5, and an anti-skid boss 64 is further arranged on the knob 61. Specifically, the rotation limiting member includes an upper rotation limiting member and a lower rotation limiting member, which are respectively used for clamping the upper clamping handle 4 and the lower clamping handle 5. Referring to fig. 9 and 10, fig. 9 is a schematic view of the upper clamping handle 4 and the lower clamping handle 5 being in a locking state, at this time, the limiting boss 63 of the upper rotation limiting member faces upward to limit the upper clamping handle 4 to be pressed downward, and the limiting boss 63 of the lower rotation limiting member faces downward to limit the lower clamping handle 5 to be pressed downward, so as to prevent the upper clamping handle 4 or the lower clamping handle 5 from being forced to loosen the male end 2 and the female end 3 after the male end 2 and the female end 3 are assembled. Referring to fig. 10 again, fig. 10 is a schematic view of the upper clamping handle 4 and the lower clamping handle 5 in a loosened state, which is equivalent to a state view of the knob 61 in fig. 9 rotated 180 degrees, where the boss of the upper limiting member faces downward, the boss of the lower limiting member faces upward, the movement of the handle is not hindered, and the male end 2 and the female end 3 can be freely released by pressing the handle. Further, an anti-slip boss 64 may be provided at the knob 61 to prevent the knob 61 from being rotated by vibration.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the technical spirit of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
