Description

Technical Field

[0001] This utility model relates to the technical field of optical fiber communication, specifically an adapter and ferrule fixing assembly. Background Technology

[0002] The adapter and ferrule are key components for realizing the active connection of optical fibers, and the stability and reliability of their connection directly affect the signal transmission quality. Currently, in existing technologies, the adapter and ferrule are generally fixed by adhesive bonding.

[0003] Specifically, operators need to precisely apply adhesive (such as UV glue) to the mating surfaces of the adapter or ferrule, then assemble and align the two parts, and finally cure the adhesive through ultraviolet irradiation to achieve fixation. However, this adhesive fixing method has many inherent drawbacks: First, its production process is cumbersome, heavily reliant on manual operation, making it difficult to guarantee the consistency of adhesive application and placement, and requiring additional curing equipment and time, resulting in low production efficiency and hindering automated mass production. Second, and more importantly, adhesive bonding inherently cannot provide effective axial mechanical preload for the interface between the adapter and ferrule. During long-term use, external factors such as changes in ambient temperature, mechanical vibration, and insertion / extraction forces can cause fatigue aging or stress cracking of the adhesive layer, leading to loosening of the interface, which in turn causes increased attenuation of the optical signal and even momentary interruption. Furthermore, once the adhesive connection is completed, subsequent maintenance and component replacement are difficult, often resulting in the scrapping of the entire connection assembly and increasing maintenance costs. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adapter and ferrule fixing assembly, which solves the technical problems of complicated process, lack of pre-tightening force, poor contact and detachment caused by the existing adapter and ferrule fixing method using glue.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: An adapter and insert fixing assembly is characterized in that it includes an adapter, an insert, and a clip, one end of the insert is inserted into one end of the adapter, the adapter and the insert are respectively provided with steps, the clip is sleeve-shaped, both ends of the clip are provided with inwardly folded edges, the two ends of the clip are respectively engaged with the outside of the steps of the adapter and the insert by the folded edges, the clip is sleeved on the outside of the ends of the adapter and the insert, and one side of the clip is provided with an opening.

[0006] In a preferred embodiment, the clip is made of elastic sheet metal.

[0007] In a preferred embodiment, the stepped connection between the clip and the adapter is U-shaped, and the stepped connection between the clip and the insert is L-shaped.

[0008] In a preferred embodiment, a protrusion is provided on the inner side of the folded edge near the opening.

[0009] In a preferred embodiment, each end of the card holder is provided with two folded edges, and the two folded edges on the same end of the card holder are symmetrically arranged.

[0010] The technical effects and advantages of this utility model are as follows: This invention utilizes a mechanical locking mechanism with clips to replace adhesive application, eliminating the cumbersome processes of adhesive application and curing, and significantly improving production efficiency. The elasticity of the clips provides continuous pre-tightening force for the connection, effectively preventing poor contact and loosening during use. Simultaneously, the raised point design prevents vibration-induced loosening, resulting in a more secure connection. It better ensures the concentricity of the connection, and the assembly process is simple and quick—a simple push locks it in place, facilitating production and maintenance.

[0012] 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.

[0013] like Figure 1 and Figure 2 As shown An adapter and insert fixing assembly includes an adapter 1, an insert 2, and a clip 3. One end of the insert 2 is inserted into one end of the adapter 1. Steps 4 are provided on both the adapter 1 and the insert 2. The clip 3 is sleeve-shaped, with inwardly folded edges 5 at both ends. The two ends of the clip 3 are respectively engaged with the outer side of the steps 4 of the adapter and the insert via the folded edges 5. The clip 3 is fitted over the ends of the adapter 1 and the insert 2, and an opening 6 is provided on one side of the clip 3. This invention achieves quick and reliable mechanical locking of the adapter 1 and the insert 2 by introducing an independent clip 3. Its core function is to replace the traditional glue application process, using the mechanical constraint force of the clip 3 to fasten the two components together, thereby avoiding the use of glue and subsequent curing processes. The clip 3 is designed as a sleeve, which can completely wrap around the connection between the adapter 1 and the insert 2. The inwardly folded edges 5 at both ends of the clip 3 can hook onto the steps 4 of the adapter 1 and the insert 2, thereby preventing the two components from detaching axially.

[0014] The clip 3 is made of elastic sheet metal. The clip 3 has the necessary elastic deformation capacity, which allows it to be opened during installation and to tightly hold the adapter 1 and the socket 2 inside after it is in place by its own rebound force, giving the adapter 1 and the socket 2 a pre-tightening force to the connection, so that the connection between the adapter 1 and the socket 2 is not prone to poor contact.

[0015] The folded edge 5 connecting the clip 3 to the step 4 of the adapter 1 is U-shaped, and the folded edge 5 connecting the clip 3 to the step 4 of the socket 2 is L-shaped. This design is compatible with the existing step structures on the conventional adapter 1 and socket 2, requiring no modifications to the existing structures of the adapter 1 and socket 2.

[0016] A protrusion 7 is provided on the inner side of the folded edge 5 near the opening 6. The protrusion 7 increases the local pressure and friction in this key locking area. This effectively prevents the clip 3 from coming loose on its own when subjected to vibration or external force, improving the reliability of the connection.

[0017] Each end of the clip 3 has two folded edges 5, which are symmetrically arranged. This ensures that the locking force applied to the adapter 1 and the ferrule 2 remains balanced and uniform. It prevents the adapter 1 and the ferrule 2 from tilting or becoming unstable due to uneven force, thus ensuring the concentricity of the connection between the adapter 1 and the ferrule 2.

[0018] The assembly process of this utility model is as follows: First, connect one end of the insert 2 to one end of the adapter 1; then, the connected adapter 1 and insert 2 are squeezed together into the inside of the clip 3 from one side of the opening 6 of the clip 3, and the assembly is completed; when squeezing in, it should be ensured that the L-shaped folded edge 5 of the clip 3 slides over and is locked on the outside of the step 4 of the insert 2, and the U-shaped folded edge 5 of the clip 3 slides over and is locked on the outside of the step 4 of the adapter 1.

[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
