It can be understood that, after the wire harness to be connected passes through the wire passing hole 232 of the stop collar 23, the wire harness is connected to the connector lug 21, and then the connector lug 21 is inserted into the outer sleeve 22 until the stop collar 212 contacts with the stop collar 221, at this moment, the cylinder head 211 is exposed out of the outer sleeve 22, and then the stop collar 23 is inserted into the outer sleeve 22, the stop collar 23 is tightly locked to the outer sleeve 22 through the locking sleeve 24, and the stop collar 23 abuts against the connector lug 21, thereby completing the assembly of the second connector 2. After the second connector is assembled, the cylindrical head 211 of the connector 21 is inserted into the first connector 1, the protrusion 214 of the cylindrical head 211 is matched with the clamping groove 12, the second connector 2 is rotated to enable the protrusion 214 to move in the clamping groove 12, the protrusion 214 is extruded under the guidance of the limiting inclined plane 13 to enable the connector 21 to move towards the bottom of the cylindrical groove 11, at the moment, the end portion of the cylindrical head 211 extrudes the first waterproof rubber pad 14 to ensure the water tightness between the cylindrical head 211 and the bottom of the cylindrical groove 11, meanwhile, the limiting head 212 and the limiting ring 221 tightly press the second waterproof rubber pad 213 to ensure the water tightness between the connector 21 and the outer clamping sleeve 22. After the locking sleeve 24 locks the position-limiting sleeve 23 to the outer sleeve 22, the position-limiting sleeve 23 tightly presses the outer sleeve 22 at the inner waterproof ring 231, thereby ensuring the water tightness between the locking sleeve 24 and the outer sleeve 22. The wire through hole 232 of the limiting sleeve 23 is provided with an outer waterproof ring 233, the inner diameter of the outer waterproof ring 233 is smaller than the diameter of the wiring harness, and when the wiring harness passes through the limiting sleeve 23 through the wire through hole 232, the outer waterproof ring 233 can effectively guarantee the water tightness of the wire through hole 232. Through foretell setting, improve the waterproof performance of connector.
Further, a sealing ring 222 is disposed on the outer side of the outer clamping sleeve 22, and after the locking sleeve 24 is screwed to the outer clamping sleeve 22, the sealing ring 222 seals the joint between the locking sleeve 24 and the outer clamping sleeve 22.
It will be appreciated that when the locking sleeve 24 is tightened on the outer ferrule 22, the sealing ring 222 is located between the locking sleeve 24 and the outer ferrule 22 and compressed by the locking sleeve 24 and the outer ferrule 22, thereby forming a reliable seal to prevent external moisture from entering the connector and improving the waterproof performance of the connector.
Further, a waterproof rubber sleeve 234 is arranged at the end part of the limiting sleeve 23.
It can be understood that when the locking sleeve 24 is screwed on the outer sleeve 22, the locking sleeve 24 presses the position-limiting sleeve 23, and the waterproof rubber sleeve 234 is between the locking sleeve 24 and the position-limiting sleeve 23, so as to prevent moisture from entering the connector between the locking sleeve 24 and the position-limiting sleeve 23, and further improve the waterproof performance of the connector.
Further, the outer end of the position limiting sleeve 23 is provided with a chamfer 235, the locking sleeve 24 is provided with a locking ring 241, and the locking ring 241 is matched with the chamfer 235.
It will be appreciated that during tightening of the locking sleeve 24, the locking ring 241 slides at the chamfer 235 and compresses the chamfer 235, and as the locking sleeve 24 is tightened, the compressive force of the locking ring 241 against the chamfer 235 increases, at which point the locking ring 241 forms a reliable seal at the chamfer 235 and thus the waterproof properties of the sleeve connector.
Furthermore, a check groove 15 is arranged at the position of the limit inclined plane 13.
It can be understood that, rotate second connector 2, make arch 214 remove in draw-in groove 12, under the direction of spacing inclined plane 13, arch 214 is extruded, make connector 21 remove to the bottom of cylindrical groove 11, arch 214 removes the back of targetting in place in draw-in groove 12, get into check groove 15, it is spacing to arch 214 through check groove 15, prevent that second connector 2 from revolving, and then prevent to take place to become flexible between second connector 2 and the first connector 1, make the tip of cylinder head 211 keep the extrusion to first waterproof rubber mat 14, guarantee the reliable water proofness in cylinder head 211 and cylindrical groove 11 bottom.
Specifically, the number of the slots 12 is three or more, the slots 12 are circumferentially and uniformly distributed along the cylindrical groove 11, and the number of the protrusions 214 is equal to the number of the slots 12.
It can be understood that, through the arrangement of the plurality of slots 12, the connector lug 21 is stressed uniformly when being clamped into the cylindrical slot 11, so as to prevent the first waterproof rubber gasket 14 and the second waterproof rubber gasket 213 from being stressed unevenly to cause untight sealing, thereby further improving the waterproof performance of the connector.
Further, the core of the connector lug 21 is provided with a circular groove 215, and a desiccant 216 is filled in the circular groove 215.
As can be appreciated, the desiccant 216 is arranged inside the connector, so that the inside of the connector can be effectively dried, and the corrosion of moisture to the internal parts of the connector can be prevented, and the reliability of the connector can be guaranteed.
