the during operation inserts the in-process of fourth spout 291 at branch 29, and fourth spout 291 can be to the inboard extrusion slider 293, can extrude snap ring 292 to the inboard after slider 293 receives the extrusion, can improve the chucking dynamics of snap ring 292 to the wire at this in-process to prevent that the electric wire from receiving to drag and taking place the damage, can also strengthen the sealed degree between wire and the connector simultaneously.
The specific working process is as follows:
in operation, when the invention is used, the first connector 1 is firstly inserted into the second connector 2, in the process of inserting the first connector 1 into the second connector 2, the auxiliary plate 12 and the sealing ring 14 are matched with the annular groove 21, so that the sealing ring 14 and the auxiliary plate 12 can be inserted into the annular groove 21, the electric plug rod 13 is also inserted into the electric plug hole 23, so that the communication between the wires can be realized, after the first connector 1 and the second connector 2 are attached to each other, the fixing ring 16 on the outer surface of the first connector 1 is rotated, the fixing ring 16 is engaged with the threads formed on the outer surface of the second connector 2, so that the fixing ring 16 can be screwed into the outer surface of the second connector 2, in the process of screwing the fixing ring 16 into the second connector 2, the pressing plate 17 can press the annular bag 24 inwards, and the first plug rods 25 which are uniformly arranged are connected in the annular bag 24 in a sliding manner, so that the first plug rods 25 can be pressed to the first plug holes 15 which are uniformly arranged and formed on the outer surface of In, the degree of fixation of connector can further be improved at this in-process, thereby prevent that the connector from receiving highly compressed influence for a long time and taking place deformation, thereby reduce the sealed degree of connector, because annular bag 24 and the first circular slot 26 intercommunication of evenly arranging, receive the extrusion back at annular bag 24, the gas in the annular bag 24 can flow into in the first circular slot 26, can extrude first circular slot 26 sliding connection's second inserted bar 27 when gas flows into in the first circular slot 26, because second inserted bar 27 and second jack 18 mutually support, thereby can crowd second inserted bar 27 into in the second jack 18 in first joint 1, can further improve the degree of fixation between first joint 1 and the second joint 2 at this in-process, thereby prevent to take place to become flexible between the connector, make the connector take place to damage.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
