Description

Technical Field

[0001] The utility model relates to the technical field of connector shells, and more specifically to a connector shell with good sealing performance. Background Art

[0002] A device with two active devices that transmit current or signals, where the male and female ends can transmit information or current after contact, is called a connector. Currently, there are nearly a hundred types of connectors needed for automobiles, and there are hundreds of connectors used for a single model. Currently, automotive connectors generally include socket connectors and plug connectors. The socket connector and the plug connector are plugged into each other to form information or current transmission. The existing socket connector and plug connector are easily affected by the external environment when connected. For example, the vibration during the operation of the car can easily cause looseness, resulting in poor sealing. In the case of poor sealing, water is easy to enter and cause short circuits, which urgently needs improvement.

[0003] In view of the above problems, regarding the technical problem that the socket connector and the plug connector are easily affected by the external environment and easily become loose when connected, after a lot of searches, a Chinese utility model with application number CN220122203U was found, which provides a connector with better sealing performance. The utility model includes a socket connector and a plug connector. The socket connector includes a socket housing and a plug-in shell arranged at the end of the socket housing, and a butt copper sheet is arranged in the plug-in shell. The plug connector includes a plug housing and a fixed housing arranged at the end of the plug housing. A limiting ring is arranged on the circumference of the end of the fixed housing, and a plug connector is arranged at the end of the fixed housing. The end of the plug connector is provided with a plug hole that cooperates with the butt copper sheet, and a part of the plug connector near the limiting ring A sealing member is also provided at the end, which includes a rubber ring sleeved on the outside of the plug connector, a plurality of sealing rings are arranged circumferentially on the outer wall of the rubber ring, and pressure strips extending toward the rubber ring are respectively provided on both sides of the end of the plug connector, and a card block is provided at the end of the pressure strip. The practical connector can improve the sealing effect of the connector by providing a sealing member to avoid the situation where the connector becomes loose and water enters due to the influence of the external environment. However, the technical solution provided by the patent has the following problems: when the connector and the docking device need to be disassembled, a plurality of sealing rings should be provided, which causes the connector and the docking device to be too tight and thus inconvenient to disassemble and open, resulting in a large amount of force required to open and the connector housing is easily damaged due to the use of a large amount of brute force, making it inconvenient to use and reducing the service life.

[0004] Therefore, the utility model provides a connector housing with good sealing performance. Utility Model Content

The body 8 can improve the sealing of the connector shell and ensure its safety. Then, the connector shell 1 or the docking device shell 8 is rotated to make the first connecting part 2 and the third connecting part 6 rotatably connected with the docking device shell 8 and the connecting part 9. When the second connecting part 4 enters the docking device shell 8, the clamping strip 401 is squeezed inward by the docking device shell 8. After the first connecting part 2, the third connecting part 6 and the connecting part 9 are rotated and connected, the rectangular protrusion provided at the tail end of the clamping strip 401 will protrude from the rectangular through hole opened on the docking device shell 8, thereby achieving a clamping effect, so that the connector shell 1 and the docking device 7 will not be accidentally rotated during use; when the connector shell 1 and the docking device 7 need to be disassembled, first press the clamping strip 401 to shrink it, and then move the movable sleeve 12 to the left to clamp the clamping strip 401. At this time, the connector shell 1 can be rotated to be disassembled.

[0026] In the embodiment of the utility model, the second connecting portion 4 is hollow and protrudes from the plug connector 5, and the cross-section of the docking device shell 8 is "concave" shaped and protrudes from the docking connector 10. By matching the second connecting portion 4 that is hollow and protrudes from the plug connector 5 with the docking device shell 8 that has a "concave" shaped cross-section and protrudes from the docking connector 10, the sealing performance of the connector shell can be improved.

[0027] When in use, first align the docking device 7 with the connector housing 1, and insert the docking head 10 into the plug connector 5. By cooperating with the second connecting portion 4 protruding from the plug connector 5 and the docking device housing 8 protruding from the docking head 10, the sealing performance of the connector housing can be improved, thereby ensuring its safety.

[0028] In the embodiment of the utility model, the outer side of the first connecting portion 2 and the inner side of the docking device housing 8 are matched with spiral patterns;

By cooperating with the docking device shell 8 having a rectangular through hole matching the rectangular protrusion at the tail end of the clamping strip 401, the second connecting part 4 can be clamped through the clamping strip 401 and the rectangular through hole when it enters the interior of the docking device shell 8.

[0032] During use, when the second connecting part 4 enters the docking device shell 8, the clamping strip 401 is squeezed inward by the docking device shell 8. After the first connecting part 2, the third connecting part 6 and the connecting part 9 are rotated and connected, the rectangular protrusion provided at the tail end of the clamping strip 401 will protrude from the rectangular through hole opened on the docking device shell 8, thereby achieving a clamping effect, so that the connector shell 1 and the docking device 7 will not be accidentally rotated due to accidental touching during use.

[0033] In the embodiment of the utility model, the movable sleeve 12 is arranged on the outside of the rectangular through hole on the docking device shell 8, and the first fixing ring 11, the second fixing ring 13 and the movable sleeve 12 are equipped with magnetic suction sheets, and the outer diameters of the first fixing ring 11 and the second fixing ring 13 are larger than the outer diameter of the movable sleeve 12. Through the movable sleeve 12 arranged on the outside of the rectangular through hole on the docking device shell 8, when the plug connector 5 needs to be separated from the docking connector 10, the clamping strip 401 can be pressed through the movable sleeve 12, thereby facilitating the first connection part 2 and the third connection part 6 to rotate open. Through the first fixing ring 11, the second fixing ring 13 and the movable sleeve 12 equipped with magnetic suction sheets, the movable sleeve 12 does not need to be manually fixed in position when in use. Through the first fixing ring 11 and the second fixing ring whose outer diameters are larger than the outer diameter of the movable sleeve 12, the movable sleeve 12 will not be separated from the docking device shell 8.

[0034] During use, when the connector housing 1 and the docking device 7 need to be separated, first press the clamping strip 401 to shrink it, then move the movable sleeve 12 to the left to clamp the clamping strip 401, and then rotate the connector housing 1 to separate them.
