The connector plug 30a also includes a second sealing ring 333, which is located between the plug core 32 and the rubber-coated inner sleeve 352a.

[0087] like Figure 29 and Figures 38-44 As shown, when assembling the connector plug 30a, the body 3842 of the micro switch 384 is positioned in the through groove 3525 of the rubber-coated sleeve 352a, so that the operating element 3844 is close to the support surface 3524d; one end of the third reset member 3804 is inserted into the second positioning hole 3528, so that... Figure 38The assembled second locking member 380a, the connecting cover 385, the upper locking operation member 388 and the second reset member 3802 are shown installed to the mounting table 3524 of the encapsulation sleeve 352a, specifically, the four cantilever arms 3527 are respectively inserted into the four first clamping slots 3856 of the connecting cover 385, the fixed block 3524a is inserted into the fixed slot 385a, the clamping column 3884 is inserted into the second positioning hole 3528, until the four buckling points 3857 are respectively clamped into the clamping slots of the four cantilever arms 3527, and the clamping column 3884 abuts against the third reset member 3804; the second screw hole 3524b on the fixed block 3524a is opposite to the first screw hole 385b, and the clamping column 3884 abuts against the third reset member 3804, so that the third reset member 3804 is connected between the upper locking operation member 388 and the encapsulation body, and the third reset member 3804 is used for pushing the upper locking operation member 388 to slide and reset. The operating element 3844 abuts against the second abutting surface 3874, and the supporting surface 3524d supports the sliding bar 3807. The power terminal 362 and the signal terminal 364 are respectively press-fitted into the first positioning slot 3254 and the second positioning slot 3256 of the plug encapsulation core 32 by using a hand press or a pneumatic tool; the second sealing ring 333 is sleeved on the connecting part 327 of the plug encapsulation core 32; the wire is cut, then the wire is stripped and immersed in tin; the wire is welded with the tail part of the power terminal 362 and the tail part of the signal terminal 364 in the plug encapsulation core 32, and the micro switch 384 is electrically connected to the corresponding wire. The connecting part 327 of the plug encapsulation core 32 is screwed to the internal thread 3522 of the encapsulation sleeve 352a, so that the second sealing ring 333 is sealingly clamped between the plug encapsulation core 32 and the encapsulation sleeve 352a; the wire passes through the wire hole 3502 of the wire sealing body 350, and the wire sealing body 350 is sealingly positioned in the inner cavity of the encapsulation sleeve 352a, so as to seal the wire with the wire sealing body 350; the encapsulation sleeve 352a is placed into an injection molding machine for encapsulation, so as to form an encapsulation tail part 359a on the connecting thread 3523 of the encapsulation sleeve 352a. The first sealing ring 331 is sleeved on the plug-in part 325, and the first sealing ring 331 is positioned in the first positioning ring groove 3250. The first reset member 345 is accommodated in the guide and turning groove 3202 of the plug encapsulation core 32, so that one end of the first reset member 345 contacts the barrier 3204. The first locking member 340 is sleeved on the plug encapsulation core 32, so that the guide and turning block 347 is accommodated in the corresponding guide and turning groove 3202, the guide and turning block 347 abuts against the end of the first reset member 345 away from the barrier 3204, the first reset member 345 has a pre-elastic force for driving the first locking member 340 to rotate relative to the plug encapsulation core 32, and the locking part 3801 of the second locking member 380a is inserted into the locking slot 3462 of the second locking member 380.

[0088] As Figure 29 And Figures 45-46As shown, when the connector plug 30 needs to be inserted into the connector socket, the second locking member 380a is slid away from the first locking member 340a relative to the rubber-coated body 35 until the locking part 3801 disengages from the locking groove 3462. The sliding surface 3814 of the locking block 3803 slides against the guide surface 3887 of the locking block 3882, causing the locking operation member 388 to slide along the operation channel 3854 towards the third reset member 3804. The third reset member 3804... The blocks are compressed until the locking block 3803 passes the locking block 3882. The third reset member 3804, being an elastic component, drives the locking operation member 388 to slide towards the second locking member 380a, causing the locking block 3803 to engage in the second slot 3881. The second stop surface 3810 stops against the inner side of the locking block 3882 and against the stop surface 3855, thereby positioning the second locking member 380a relative to the rubber-coated sleeve 352a. The second reset member...

[0089] 3802 is compressed by the second locking member 380a; simultaneously, the operating element 3844 slides from the second abutment surface 3874 to the first abutment surface 3872, and the first abutment surface 3872 presses the operating element 3844 to trigger the micro switch 384 and feed back a power-off signal, thereby de-energizing the connector plug 30. The insertion method of the connector plug 30a and the connector socket in the second embodiment is the same as that in the first embodiment, and will not be repeated here. When the connector plug 30a is inserted into the connector socket, the first sealing ring 331 is sealed between the socket core and the plug core 32 to enhance the sealing effect between the connector plug 30a and the connector socket. Pressing the locking operation member 388 to slide it toward the mounting platform 3524 compresses the third reset member 3804 until the locking block 3882 disengages from the locking block 3803. The second reset member 3802 elastically resets and pushes the second locking member 380a toward the first locking member 340a until the locking part 3801 inserts into the locking groove 3462 to prevent the first locking member 340a from being relative to the connector socket and to prevent the connector plug 30a from disengaging from the connector socket. At the same time, the operating element 3844 slides from the first abutment surface 3872 to the second abutment surface 3874. At this time, the connector plug 30a and the connector socket are energized to achieve automatic locking of the connector plug 30a and the connector socket by the first locking member 340, and axial positioning of the connector plug 30a and the connector socket.

[0090] When the connector plug 30a is separated from the connector socket, the second locking member 380a is slid away from the first locking member 340a relative to the rubberized main body 35, until the locking portion 3801 is separated from the locking groove 3462, the sliding surface 3814 of the clamping block 3803 is slidably pushed against the guide sliding surface 3887 of the clamping block 3882, the upper locking operating member 388 is slid along the operating channel 3854 to the third reset member 3804, the third reset member 3804 is compressed, until the clamping block 3803 passes the clamping block 3882, the elastic reset member of the third reset member 3804 drives the upper locking operating member 388 to slide to the second locking member 380a, so that the clamping block 3803 is clamped in the second clamping groove 3881, and the second stop surface 3810 is stopped on the inner side surface of the clamping block 3882, so that the second locking member 380a is positioned relative to the rubberized sleeve 352a, and the second reset member 3802 is compressed by the second locking member 380a; at the same time, the operating element 3844 is slid from the second abutting surface 3874 to the first abutting surface 3872, and the first abutting surface 3872 presses the operating element 3844 to trigger the micro switch 384 and feed back a power-off signal, so that the connector plug 30 is powered off. The connector plug 30a in the second embodiment is separated from the connector socket in the same way as the first embodiment, and will not be repeated here.

[0091] After the second locking member 380a of the connector plug 30a in the second embodiment of the application is unlocked with the first locking member 340a, the micro switch 384 is pressed and triggered by the second locking member 380a to feed back a power-off signal, so that the connector plug 30a is powered off, ensuring that the connector plug 30a is inserted or separated from the connector socket in a non-live state, thereby eliminating the problem of arc striking caused by the insertion and separation of the live connector plug 30a and the connector socket, avoiding damage to the connector caused by excessive temperature, and improving the service life of the connector. Secondly, by pressing the upper locking operating member 388 to make the clamping block 3803 separate from the second clamping groove 3881, and under the elastic pushing of the second reset member 3802, the second locking member 380a slides to the first locking member 340a, to realize the automatic locking of the second locking member 380a and the first locking member 340a, which is convenient to use and simple to operate. In addition, the connector plug 30a and the connector socket are automatically locked by the first locking member 340a, which is convenient for the insertion and locking of the connector plug 30a and the connector socket.
