The depth of the inner ground flange seal 151, inner neutral flange seal 161 and inner neutral flange seal 141 is less than the height of the hot 46, neutral 44 and ground 45 openings.
In order to further enhance the combination effect between the coupling sealing slide cylinder and the coupler, and not to cause dislocation influence and interfere the whole drainage effect, the coupling sealing slide cylinder 4 slides in pair with the slide cylinder matching extension sleeve 214 in the coupler 2 through the elastic reset cavity 48, and a slide cylinder reset spring 51 is further arranged between the elastic reset cavity 48 and the slide cylinder matching extension sleeve 214, so that in a normal state, the live wire dislocation drain hole 41, the zero wire dislocation drain hole 42 and the ground wire dislocation drain hole 43 on the coupling sealing slide cylinder 4 can be in one-to-one correspondence with the live wire drain hole 261, the zero wire drain hole 241 and the ground wire drain hole 251, and drainage is facilitated.

When the coupling sealing slide barrel 4 slides up and down based on the matching of the live wire coupling sleeve 26, the neutral wire coupling sleeve 24, the ground wire coupling sleeve 25 and the slide barrel extension sleeve 214, the matching states of the live wire dislocation drain hole 41, the neutral wire dislocation drain hole 42 and the ground wire dislocation drain hole 43 with the live wire drain hole 261, the neutral wire drain hole 241 and the ground wire drain hole 251 slide along with the sliding, and change. In a normal state, the openings completely correspond to each other, and when the coupling seal spool 4 slides to contact the barrier layer 21, the live wire offset drain hole 41, the zero wire offset drain hole 42, and the ground wire offset drain hole 43 are completely offset from the openings of the live wire drain hole 261, the zero wire drain hole 241, and the ground wire drain hole 251, so that sealing is achieved.
In order to further increase the safety, a sequential drainage mode is adopted, so that even if one module fails to be sealed, the module cannot be interfered, and the vertical heights of the live wire drain hole 261, the zero line drain hole 241 and the ground wire drain hole 251 from the barrier layer 21 are different and are distributed in a staggered manner.
Preferably, in the above technical solution, the fire line is most dangerous, and therefore, the fire line bridging module is drained first, then the zero line bridging module is drained, and finally the ground line bridging module is drained, and the vertical height from the fire line drain 261 to the barrier layer 21 is higher than the vertical height from the zero line drain 241 to the barrier layer 21. The vertical height of the neutral drain hole 241 from the barrier layer 21 is higher than the vertical height of the ground drain hole 251 from the barrier layer 21. The length of the live wire contact pad 71 is smaller than the length of the neutral wire contact pad 72. The length of the neutral contact 72 is shorter than that of the ground contact 73, so that the actual stroke distance corresponds to the actual stroke distance.

In order to realize the fixed matching relationship of the insert and the coupler, a fastening module is also included. The fastening module can fasten and match the inlay device 1 and the coupler 2 in a buckling, bolt and magnetic attraction mode. In the specific magnetic attraction mode, the coupler 2 is additionally provided with the coupling magnet 5 which is made of a permanent magnet or can attract objects, and the insert 1 is additionally provided with the matching magnet 13 which is made of a permanent magnet or can attract objects. One of the coupling magnet 5 and the matching magnet 13 is necessarily provided with a permanent magnet material.
When a strong connection relation is needed, the insert and the coupler are stably fixed for a long time in a bolt mode.
In order to further improve the adaptability and stability of the whole structure, the sealing cover 3 is further provided with a bus hole 31 for accommodating a line body matched with the module sleeving column 61. The plugboard shell 8 is provided with an installation gap 82, a line hole 81 and an installation hole 83, the inner diameter of the installation gap 82 is larger than the outer diameter of the coupling sealing sliding barrel 4, and the coupling sealing sliding barrel 4 is sleeved in the installation gap 82. The detachable waterproof sealing coupling device is abutted against the inner extension of the mounting notch 82 and is fixed in the flashboard housing 8 through the bolt 84 and the mounting hole 83. The wire lines are respectively connected with the detachable waterproof sealing coupling device, namely the wire lines penetrate out of the bus hole 31 after being connected with the module sleeving column 61 and then are collected to penetrate out through the line hole 81. The inserter 1 is further provided with a hand-held unit 11 and a bus 12.
Preferably, a sealing ring is further provided between the sealing cover 3 and the coupler 2, and a corresponding sealing ring is also provided at the bus hole 31 of the sealing cover 3, so as to achieve an integral sealing effect.
The working principle is as follows: when the firing line embedded end 16, the null line embedded end 14 and the ground wire embedded end 15 of the embedded device are inserted into the firing line coupling sleeve 26, the null line coupling sleeve 24 and the ground wire coupling sleeve 25 of the coupler, the firing line embedded end 16, the null line embedded end 14 and the ground wire embedded end 15, the firing line embedded end 16 firstly completes drainage with the firing line contact plate 641 for contact, the firing line embedded end 16 further penetrates into the firing line coupling sleeve 26 along with further extrusion, the firing line embedded end 16 completely penetrates into the firing line coupling sleeve 26, the firing line drain hole 261 is blocked by the insulating layer 17 wrapping the firing line embedded end 16, the null line embedded end 14 completes drainage with the null line contact plate 651 for contact, the null line embedded end 14 further penetrates into the null line coupling sleeve 24 along with further extrusion, the null line embedded end 14 completely penetrates into the null line coupling sleeve 24, the null line drain hole 241 is blocked by the insulating layer 17 wrapping the null line embedded end 14, at this time, the ground wire embedded end 15 and the ground wire contact plate 631 complete drainage and contact, with further extrusion, the ground wire embedded end 15 further penetrates into the ground wire coupling sleeve 25, the ground wire embedded end 15 completely sinks into the ground wire coupling sleeve 25, when the ground wire drainage hole 251 is blocked by the insulating layer 17 wrapping the ground wire embedded end 15, at this moment, the embedded device 1 contacts with the extension of the coupling sealing slide cylinder 4, with further extrusion of the embedded device 1, the coupling sealing slide cylinder 4 slides along with the coupling sealing slide cylinder 4 after overcoming the elastic force of the slide cylinder reset spring 51, and at this moment, the live wire dislocation drainage hole 41, the null wire dislocation drainage hole 42 and the ground wire dislocation drainage hole 43 completely dislocate with the openings of the live wire drainage hole 261, the null wire drainage hole 241 and the ground wire drainage hole 251, so as to realize sealing.
At this moment, live wire touch panel 641, zero line touch panel 651 and ground wire touch panel 631 receive the extrusion when, then can drive corresponding spacing extension insulating sleeve and slide down, simultaneously, corresponding extension touch post also can contact corresponding ground wire and touch platform 73, the live wire touches platform 71 or zero line and touches platform 72, although live wire touch panel 641 receives the extrusion first, zero line touch panel 651 time, ground wire touch panel 631 is last, however, because distance and stroke, they still touch corresponding live wire simultaneously and touch platform 641, zero line touch platform 651 and ground wire touch platform 631, at this moment, just accomplish the live wire bridging, zero line bridging and ground wire bridging, simultaneously, before the bridging, whole sealing work has also been accomplished early.
After above-mentioned cooperation is accomplished, at last when the sealed slide cartridge of inlay ware and coupling contacts, inside unnecessary water and the air of not letting out, along with the sealed slide cartridge of inlay ware and coupling further extrusion fit, then can lead to inside water pressure and atmospheric pressure too big, then can generate bounce-back force, carry out the counter force with fastening module and counter act, at this moment, must influence normal use, increase the cooperation back of inlay ware and coupler, receive probability and the risk that external force influences and break away from. The ground wire draining balance hole 153, the zero line draining balance hole 143, the live wire draining balance hole 163 and the corresponding elastic shrinkage sealing film 18 are arranged, so that the water pressure and the air pressure in the respective chambers can be balanced, the balance is achieved, even, the suction is formed, and the matching effect is further improved.
If the insert and the coupling sealing sliding barrel are excessively sealed due to proper water pressure and air pressure and an excessively flexible inner flange sealing ring, the insert and the coupling sealing sliding barrel are too difficult to insert and insert, and related structures are easily damaged, so that subsequent use is influenced.
