Description

Technical Field

[0001] This utility model relates to the field of fiber optic connectors, and in particular to a quick-release and anti-detachment structure for an end-face sealing ring. Background Technology

[0002] When a fiber optic connector is inserted into a device (such as an optical module or optical transceiver), a seal is required between the housing and the device interface to prevent dust or moisture from entering. The sealing ring is usually installed on the flange or interface end face of the connector housing.

[0003] In connectors, end face seals are frequently required. However, during assembly, to prevent the seals from falling off during use, adhesive is often applied to the end face sealing groove, which significantly reduces the assembly efficiency of the connector. To improve production efficiency, this paper proposes a quick-install anti-fall-off structure for end face seals, which can prevent the seals from falling off without adhesive application, eliminating the adhesive application step in the production process and improving production efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a quick-install anti-detachment structure for end face sealing rings, which aims to solve the problem in the prior art that "applying adhesive in the end face sealing groove greatly reduces the assembly efficiency of the connector".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick-installation anti-detachment structure for an end-face sealing ring, comprising an end-face O-ring and a connector housing flange. The top of the connector housing flange is provided with an interface end face, and the top of the connector housing flange is provided with an end-face sealing groove for accommodating the end-face O-ring. The top edge of the end-face sealing groove is provided with a buckle to prevent the end-face O-ring from detaching. The buckle is inclined inward into the end-face sealing groove, and the end-face O-ring is located inside the end-face O-ring.

[0006] As a further description of the above technical solution:

[0007] The end face O-ring is made of silicone.

[0008] As a further description of the above technical solution:

[0009] The top of the O-ring on the end face is higher than the interface end face by a certain distance.

[0010] As a further description of the above technical solution:

[0011] The undercut is configured in two sets, with the two sets of undercuts respectively located on both sides of the end face sealing groove.

[0012] As a further description of the above technical solution:

[0013] The surface of the end face O-ring is in contact with the undercut surface.

[0014] As a further description of the above technical solution:

[0015] The width of the end face sealing groove is equal to the wire diameter of the end face O-ring.

[0016] As a further description of the above technical solution:

[0017] The depth of the end face sealing groove is at least 0.6 times greater than the diameter of the end face O-ring.

[0018] As a further description of the above technical solution:

[0019] The connector housing flange and the snap fastener are manufactured as a single piece.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, two sets of inverted inclined structures are tightly fitted to the surface of the end face O-ring seal. The inner flange of the inverted buckle clamps the outer edge of the end face O-ring seal, forming an anti-loosening lock and continuously providing radial constraint to prevent the end face O-ring seal from popping out during vibration, impact or repeated disassembly and assembly. It can prevent the seal from falling off without applying glue, saving the glue application step in the production process and improving production efficiency.

[0022] 2. In this utility model, by pressing the connector housing flange with the end face of the connected part, the part of the end face O-ring that is higher than the interface end face is compressed and deformed. The softness and extensibility of silicone fill the micro gap between the contact surfaces to achieve end face sealing. At the same time, the fluidity of silicone can adapt to the small deviations of the contact surfaces to ensure long-term sealing reliability. Attached Figure Description

[0029] 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.

[0030] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a quick-install anti-detachment structure for an end face sealing ring, including an end face O-ring 11 and a connector housing flange 21. The end face O-ring 11 is made of silicone, which provides a certain degree of mobility while sealing. By using the softness and extensibility of silicone, the end face contact can be adapted to meet the self-adaptability and internal sealing requirements of the silicone by extruding the silicone, adapting to different surface roughness or deformation requirements, while also having a certain degree of mobility to enhance sealing stability.

[0031] Reference Figure 1 - Figure 3 The connector housing flange 21 has an interface end face 22 on its top. The interface end face 22 fits against the end face of the connected component to form the main sealing interface. The top of the end face O-ring 11 is higher than the interface end face 22 by a certain distance, so that the end face O-ring 11 can still maintain an effective seal when under pressure. The top of the connector housing flange 21 has an end face sealing groove 221 for accommodating the end face O-ring 11. The width of the end face sealing groove 221 is equal to the wire diameter of the end face O-ring 11, and the depth of the end face sealing groove 221 is at least 0.6 times greater than the wire diameter of the end face O-ring 11. The bottom of the end face sealing groove 221 and the surface of the end face O-ring 11 provide initial preload force, which, combined with the elasticity of silicone, achieves dynamic sealing compensation.

[0032] Reference Figure 2 - Figure 4 The top edge of the end face sealing groove 221 is provided with a buckle 23 to prevent the end face O-ring 11 from falling off. The connector housing flange 21 and the buckle 23 are integrally molded to enhance the strength and reliability of the buckle 23. The buckle 23 is provided in two sets, which are respectively provided on both sides of the end face sealing groove 221. The buckle 23 is inclined inward into the end face sealing groove 221. The inclined design makes it easy for the end face O-ring 11 to slide in during assembly, while using reverse resistance to prevent it from falling off.

[0033] Reference Figure 2 - Figure 4 The end face O-ring 11 is located inside the end face O-ring 11. The surface of the end face O-ring 11 is in contact with the surface of the buckle 23. The buckle 23 is used to prevent the end face O-ring 11 from falling off due to vibration, pressure changes or external force during long-term use.

[0034] Working principle: When installing the sealing ring, first wipe the end face of the pin, the inner wall of the coupling tube, and the flange 21 of the connector housing with anhydrous alcohol or special cleaning agent to ensure that there is no dust or oil. Then, confirm that the end face O-ring 11 is not damaged or deformed. Then, embed the end face O-ring 11 into the end face sealing groove 221. Since the width of the end face sealing groove 221 is equal to the wire diameter of the end face O-ring 11, and the depth is designed to be more than 0.6 times the wire diameter of the end face O-ring 11, the end face O-ring 11 is uniformly compressed in the end face sealing groove 221 to form an initial preload while retaining sufficient compression space.

[0035] When the connector housing flange 21 is pressed against the end face of the connected component, the portion of the end face O-ring 11 that is higher than the interface end face 22 is compressed and deformed. The softness and extensibility of the silicone fill the micro gaps between the contact surfaces to achieve end face sealing. At the same time, the fluidity of the silicone can adapt to the slight deviations of the contact surfaces, ensuring long-term sealing reliability.

[0036] The inclined structure of the two sets of inverted buckles 23 fits tightly against the surface of the end face O-ring seal 11. The inner flange of the inverted buckle 23 clamps the outer circle of the end face O-ring seal 11 to form an anti-disengagement lock and continuously provides radial constraint to prevent the end face O-ring seal 11 from popping out during vibration, impact or repeated disassembly and assembly. The entire structure does not require additional snap rings or adhesives, and can achieve quick installation and anti-disengagement effect of the end face O-ring seal 11, meeting the requirements of quick assembly and high-reliability sealing.

[0037] During long-term use, even if the contact surface undergoes slight deformation due to temperature changes or mechanical stress, the elasticity of the silicone end face O-ring 11 can automatically compensate for the deformation and maintain the sealing performance. At the same time, the inverted buckle 23 always applies a reverse locking force through the inclined surface to keep the end face O-ring 11 stably installed and avoid sealing failure caused by the end face O-ring 11 falling off.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
