Description

Technical Field

[0001] This utility model relates to a connector sealing structure. Background Technology

[0002] In outdoor applications, especially under exposed conditions on towers, RF coaxial connectors require internal waterproofing from equipment manufacturers to prevent moisture from entering the device through the connector's interior. For example... Figure 14 The diagram shows a typical structure for connectors with internal sealing and waterproofing requirements. A groove is designed on the cylindrical surface of the inner conductor, within which a circular rubber sealing ring is installed. Similarly, a groove is designed on the cylindrical surface of the insulating medium, within which a circular rubber sealing ring is installed. After the sealing ring on the inner conductor is inserted into the inner hole of the insulating medium, it is compressed radially towards the center, undergoing elastic deformation within the groove. This creates a continuous contact around the bottom of the inner conductor groove and around the inner hole of the insulating medium, thus forming an axial seal. Similarly, the sealing ring within the insulating medium groove also forms a seal around the bottom of the insulating medium groove and around the inner hole of the outer shell. In this way, moisture cannot enter the device's interior (located on the left mounting surface) through the tiny gaps between the inner conductor and the insulating medium, and between the insulating medium and the outer shell, from the right connector port, ensuring the normal operation of the device.

[0003] In practical use, due to the small size of the sealing ring, especially the circular diameter in some small-sized products, the sealing ring needs to be squeezed into the inner hole during assembly. This can lead to the sealing ring being squeezed out or even breaking during actual operation. In practice, lubricating the sealing ring with grease and designing a tapered guide structure at the orifice are often used to ensure the sealing ring can smoothly enter the inner hole with minimal resistance. However, grease is difficult to clean and can contaminate the product, thus having limited effectiveness. Therefore, this utility model proposes a connector sealing structure to solve the above problems. Utility Model Content

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example:

[0037] like Figure 1-14 As shown, this embodiment proposes a connector sealing structure, including a housing 10, an insulating medium block 20 disposed inside the housing 10, and an inner conductor 30 disposed inside the insulating medium block 20;

[0038] The insulating medium block 20 has an installation through hole 24, and a first installation cone surface 23 is provided in the installation through hole 24. A first connecting cone surface 12 is provided inside the outer shell 10. A connecting sealing ring 50 is sleeved on the outer wall of the insulating medium block 20, and an installation sealing ring 40 is sleeved on the outer wall of the inner conductor 30. The insulating medium block 20 is snapped into the outer shell 10, so that the connecting sealing ring 50 contacts the first connecting cone surface 12 for sealing. The inner conductor 30 is snapped into the installation through hole 24, so that the installation sealing ring 40 contacts the first installation cone surface 23 for sealing.

[0039] In this embodiment, when assembling the outer shell 10, the insulating medium block 20 and the inner conductor 30, the inner conductor 30 is snapped into the mounting through hole 24 so that the mounting sealing ring 40 contacts the first mounting cone surface 23 for sealing. Then, the insulating medium block 20 together with the inner conductor 30 is assembled into the outer shell 10 so that the connecting sealing ring 50 contacts the first connecting cone surface 12 for sealing, thereby completing the sealing process during the assembly process.

[0040] Unlike traditional sealing methods, this sealing method ensures that the sealing gasket is not subjected to additional damaging forces during assembly, maintaining its complete shape for sealing. It eliminates the need for a guide structure for sealing ring assembly, additional processes such as applying lubricant, and requires no additional sealing rings to guarantee a reliable seal. This structure is simple, reliable, low-cost, easy to manufacture, and boasts a high yield rate, significantly improving efficiency, saving costs, and offering broad application prospects.

[0041] Specifically, the outer wall of the inner conductor 30 is provided with a second mounting cone surface 33, and the mounting sealing ring 40 is disposed at the second mounting cone surface 33;

[0042] The first mounting cone surface 23 and the second mounting cone surface 33 press against the mounting sealing ring 40 to seal it.

[0043] In this embodiment, when the inner conductor 30 is assembled into the mounting through hole 24, the second mounting cone surface 33 drives the mounting sealing ring 40 to move until the mounting sealing ring 40 contacts the first mounting cone surface 23. At this time, the inner conductor 30 continues to move and be assembled in the mounting through hole 24. The second mounting cone surface 33 continues to drive the mounting sealing ring 40 to move. The first mounting cone surface 23 and the second mounting cone surface 33 squeeze the mounting sealing ring 40, so that the mounting sealing ring 40 fully fills the space between the first mounting cone surface 23 and the second mounting cone surface 33 to seal.

[0044] Specifically, the outer wall of the insulating medium block 20 is provided with a second connecting cone surface 22, and the connecting sealing ring 50 is disposed at the second connecting cone surface 22;

[0045] The first connecting cone surface 12 and the second connecting cone surface 22 press against the connecting sealing ring 50 to seal it.

[0046] In this embodiment, when the insulating medium block 20 is assembled in the outer shell 10, the second connecting cone surface 22 drives the connecting sealing ring 50 to move until the connecting sealing ring 50 contacts the first connecting cone surface 12. At this time, the insulating medium block 20 continues to move and be assembled in the outer shell 10. The second connecting cone surface 22 continues to drive the connecting sealing ring 50 to move. The first connecting cone surface 12 and the second connecting cone surface 22 squeeze the connecting sealing ring 50, so that the connecting sealing ring 50 fully fills the space between the first connecting cone surface 12 and the second connecting cone surface 22 for sealing.

[0047] Specifically, an mounting ring groove 32 is provided on the outer wall of the inner conductor 30, the mounting ring groove 32 is matched with the second mounting cone surface 33, and the mounting sealing ring 40 is sleeved in the mounting ring groove 32.

[0048] In this embodiment, the mounting ring groove 32 facilitates the installation of the sealing ring 40 onto the inner conductor 30, thus facilitating the sealing process.

[0049] Specifically, a connecting ring groove 21 is provided on the outer wall of the insulating medium block 20. The connecting ring groove 21 is matched with the second connecting cone surface 22, and the connecting sealing ring 50 is sleeved in the connecting ring groove 21.

[0050] In this embodiment, the connecting ring groove 21 facilitates the connection of the sealing ring 50 onto the insulating medium block 20, thus facilitating the sealing process.

[0051] Specifically, a mounting clip ring 31 is provided on the outer wall of the inner conductor 30, and the mounting clip ring 31 is interference-fitted into the mounting through hole 24.

[0052] In this case, the insulating dielectric block 20 is made of polytetrafluoroethylene material and has a certain deformation capability.

[0053] In this embodiment, when the mounting snap ring 31 enters the mounting through hole 24, the deformation capability of the insulating medium block 20 allows the mounting snap ring 31 to be interference-fitted into the mounting through hole 24. After the inner conductor 30 is assembled in place, the inner conductor 30 and the mounting through hole 24 can remain stable, avoiding axial displacement. The pressure of the first mounting cone surface 23 and the second mounting cone surface 33 on the mounting sealing ring 40 can be maintained, thus maintaining the sealing performance.

[0054] Specifically, a connecting snap ring 11 is provided on the inner wall of the outer shell 10, and the connecting snap ring 11 is interference-fitted on the outer wall of the insulating medium block 20.

[0055] In this embodiment, when the connecting snap ring 11 is sleeved on the outer wall of the insulating medium block 20, the connecting snap ring 11 is pressed against the outer wall of the insulating medium block 20 by means of the deformation capability of the insulating medium block 20 and the interference fit of the connecting snap ring 11. After the insulating medium block 20 is assembled in place, the insulating medium block 20 and the outer shell 10 can remain stable, avoiding axial displacement. The pressure of the first connecting cone surface 12 and the second connecting cone surface 22 on the connecting sealing ring 50 can be maintained, thus maintaining the sealing performance.

[0056] Specifically, the taper of the first mounting cone surface 23 is smaller than the taper of the second mounting cone surface 33;

[0057] The taper of the first connecting conical surface 12 is smaller than the taper of the second connecting conical surface 22.

[0058] In this embodiment, since the first mounting cone surface 23 and the second mounting cone surface 33 are not parallel, and the first connecting cone surface 12 and the second connecting cone surface 22 are not parallel, when the mounting sealing ring 40 and the connecting sealing ring 50 are installed, in the axial direction, the mounting sealing ring 40 and the connecting sealing ring 50 are not compressed across their entire cross-section simultaneously, but are gradually compressed from the outside inwards, with the compressed area becoming larger and the compression becoming tighter. During the connector assembly process, there are axial tolerances, and there will be some errors in the axial relative positions between the parts. If the same cone surface angle is used, at the tolerance limit, the distance between the two cone surfaces of the mounting sealing ring 40 and the connecting sealing ring 50 may be greater than the thickness of the mounting sealing ring 40 and the connecting sealing ring 50, resulting in the mounting sealing ring 40 and the connecting sealing ring 50 not being compressed or not compressed tightly, leading to seal failure. However, by using cone surface compression at different angles, even at the tolerance limit, it can still be ensured that the mounting sealing ring 40 and the connecting sealing ring 50 near the outside have been compressed to form a seal.

[0059] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
