Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a field connector and connection assembly. Background Technology

[0002] With the rapid development of fiber optic communication technology, the coverage and number of fiber optic connectors are increasing. In environments with suitable temperature and humidity, such as FTTH and FTTR applications, field connectors are generally chosen based on factors such as cost, ease of construction, and service activation time.

[0003] Assembling the field connectors requires stripping the optical cable on-site and then cutting it to a fixed length using a special tool to complete the assembly.

[0004] However, the common practice for assembling connectors in the field is to confirm the optical specifications upon activation. However, during subsequent use, issues such as insecure fixing and material shrinkage can lead to excessive link loss, which in turn can result in a certain percentage of after-sales problems. Summary of the Invention

[0005] This application provides a field connector and connection assembly to solve the problem in related technologies where field connectors suffer excessive link loss during subsequent use due to factors such as insecure fixing and material shrinkage.

[0006] In a first aspect, a field connector is provided, comprising:

[0007] Main components;

[0008] A slide rail assembly, the slide rail assembly including a slide rail mounted on the main body and a wire clip mounted on the slide rail for securing the optical cable to the slide rail;

[0009] A side-flip cover is provided on the main body and covers the slide rail and the wire buckle. The side-flip cover is provided with an adhesive injection part for injecting glue to bond and fix the optical fiber of the optical cable to the slide rail assembly.

[0010] In some embodiments, the glue injection portion is a glue injection hole formed on the side flap.

[0011] In some embodiments, the glue injection hole is provided with a glue package containing glue, colloidal particles or colloidal powder, wherein the colloidal particles or colloidal powder are particles or powders that have been melted by microwave heating.

[0012] Alternatively, the injection hole may be provided with multiple glue packets, each of which contains one of the components of a multi-component adhesive.

[0013] In some embodiments, the main body, slide rail assembly, and / or side flap are provided with puncture devices for puncturing the rubber package.

[0014] In some embodiments, the size of the dispensing orifice is configured to allow colloidal particles or powders of a preset particle size to pass through, wherein the colloidal particles or powders are particles or powders that have been melted by microwave heating.

[0015] In some embodiments, the glue injection section includes a glue package containing glue, colloidal particles, or colloidal powder. The colloidal particles or powder are particles or powders that have been melted by microwave heating. The glue package is disposed on the inner wall of the side flap.

[0016] In some embodiments, the main body, slide rail assembly, and / or side flap are provided with puncture devices for puncturing the rubber package.

[0017] In some embodiments, the slide rail assembly further includes a fiber routing channel for the optical fiber of the optical cable to pass through and connect to the pre-embedded fiber in the ferrule assembly. The fiber routing channel is disposed on the slide rail and the wire buckle. The fiber routing channel includes a micro-bend redundant section near the ferrule assembly and an adhesive section away from the ferrule assembly. The glue injection portion is disposed corresponding to the adhesive section.

[0018] The puncture component is an overflow prevention part used to prevent glue from overflowing into the micro-bend redundant section.

[0019] In some embodiments, the slide rail assembly further includes a fiber routing channel for the optical fiber of the optical cable to pass through and connect to the pre-embedded fiber in the ferrule assembly. The fiber routing channel is disposed on the slide rail and the wire buckle. The fiber routing channel includes a micro-bend redundant section near the ferrule assembly and an adhesive section away from the ferrule assembly. The glue injection portion is disposed corresponding to the adhesive section.

[0020] The adhesive section or the side flap is provided with an anti-overflow part to prevent adhesive from overflowing into the micro-bend redundant section.

[0021] In a second aspect, a connection component is provided, comprising an adapter and a field connector as described above that mates with the adapter.

[0022] The beneficial effects of the technical solution provided in this application include:

[0023] This application uses an adhesive injection point on the side cover to apply adhesive to the optical fiber of the optical cable, thereby bonding and fixing the optical fiber to the slide rail assembly, making the optical fiber and the slide rail assembly an integrated structure. This integrated bonding and fixing of the optical fiber and the slide rail assembly is not a conventional mechanical locking structure. This integrated structure can withstand a certain amount of stress, preventing the optical fiber from retracting. This stress comes from changes in environmental temperature and humidity and changes in the material itself. This stress can indirectly cause displacement of the optical fiber or cable, thus solving the problem of excessive link loss caused by factors such as insecure fixing and material shrinkage during subsequent use of field connectors. This improves the product assembly qualification rate, reduces after-sales service ratios, lowers the maintenance costs for service providers, and enhances network feasibility for end consumers.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] After extensive research, the applicant found that most existing field connectors on the market use mechanical locking to fix optical fibers and cables. When the entire product is subjected to external force, the optical cable may move, or the material may undergo slight deformation due to changes in ambient temperature, causing the optical cable to move. In both cases, the bare optical fiber at the stripped and cut point of the optical cable may retract, changing the state between the fiber and the pre-embedded fiber in the field connector ferrule from a tight fit to a gap, resulting in increased optical path loss and, in severe cases, signal loss.

[0034] When activating services, service providers' staff rely solely on tools to assemble on-site connectors and activate the service. Due to differences in assembly techniques, if the operation is not performed according to requirements, these potentially problematic on-site connectors may not show any abnormalities at the time, but they will experience increased wear and tear within 1 to 2 weeks after service activation, affecting the network operation of end customers and requiring the service provider to conduct on-site repairs again, thus increasing the service provider's maintenance costs.

[0035] Based on this, this application provides a field connector to solve the above problems, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the field connector includes a main body 1, a slide rail assembly, and a side-flip cover 4. The slide rail assembly includes a slide rail 2 mounted on the main body 1 and a wire clip 3 mounted on the slide rail 2 for fixing the optical cable 100 to the slide rail 2. The slide rail can move on the main body 1 to guide the stripped optical fiber 101 of the optical cable 100 to connect with the pre-embedded fiber in the ferrule assembly 5. The side-flip cover 4 covers the main body 1 and the slide rail 2 and wire clip 3. The side-flip cover 4 is laterally fastened to lock with the main body 1 and applies pressure to the wire clip 3 to ensure that the optical cable 100 is locked. The side-flip cover 4 is provided with an injection part for injecting glue to bond and fix the optical fiber 101 of the optical cable 100 to the slide rail assembly.

[0036] This application applies adhesive to the optical fiber 101 of the optical cable 100 through the adhesive injection part on the side cover 4, thereby bonding and fixing the optical fiber 101 to the slide rail assembly, making the optical fiber 101 and the slide rail assembly an integral structure. This bonding and fixing of the optical fiber 101 to the slide rail assembly into an integral structure is not a conventional mechanical locking structure. This integral structure can withstand a certain amount of stress, preventing the optical fiber from retracting. This stress comes from changes in environmental temperature and humidity and changes in the material itself. This stress can indirectly cause displacement of the optical fiber or cable, thereby solving the problem of excessive link loss caused by factors such as insecure fixing and material shrinkage in field connectors during subsequent use. This improves the product assembly qualification rate, reduces after-sales service ratios, lowers the maintenance costs for service providers, and enhances network feasibility for end consumers.

[0037] The optical cable 100 is secured to the slide rail 2 by the lateral snap-fit ​​of the side cover 4 and the application of pressure to the wire clip 3. However, since it is still a mechanical locking scheme, to further secure it, the optical cable 100 can also be glued to the slide rail assembly while simultaneously using the glue applicator to bond the optical fiber 101 to the slide rail assembly. This makes the optical cable 100, the stripped optical fiber 101, and the slide rail assembly a single integrated structure. The bonding and securing of the optical cable 100 can be achieved by adjusting or optimizing the amount of glue or the glue application position.

[0038] It is understandable that when bonding and fixing the optical fiber 101 or optical cable 100 to the slide rail assembly, it is preferable to fix it to the wire buckle 3. This is because: after the optical fiber 101 of the stripped optical cable 100 is exposed, it will connect with the pre-embedded fiber of the ferrule assembly 5. In order to prevent the glue from flowing to the connection position and contaminating the optical fiber during injection, the glue will be injected as close as possible to the wire buckle 3. Thus, the optical fiber 101 and optical cable 100 can be bonded with the least amount of glue, which can achieve the purpose, reduce the risk of contamination, and reduce costs. On this basis, it can be further bonded and fixed to the slide rail 2, so that the optical cable 100, the stripped optical fiber 101, the wire buckle 3, and the slide rail 2 form an integrated structure. The more parts included in the integrated structure, the stronger its overall resistance to external stress, and the better it can prevent the optical fiber from retracting.

[0039] Since the slide rail 2 is installed on the main body 1, considering that the more parts the integrated structure contains, the stronger its overall resistance to external stress, and the better it can prevent the optical fiber from retracting, furthermore, while using the glue injection part to glue and fix the optical fiber 101 to the slide rail assembly, the main body 1 can also be glued and fixed to the slide rail assembly, so that the optical cable 100, the stripped optical fiber 101, the main body 1, the wire buckle 3, and the slide rail 2 are glued into an integrated structure, further enhancing the integrated structure's ability to withstand external stress.

[0040] This application integrates an optical cable 100, a stripped optical fiber 101, a main body 1, a wire buckle 3, and a slide rail 2 into a single structure. Based on this, in order to achieve the bonding purpose, the adhesive injection part of this application may include at least two types.

[0041] (1) In the first type, the glue injection part is a glue injection hole 40 opened on the side cover 4.

[0042] In this example, the glue injection part is the glue injection hole 40, into which glue, glue particles or glue powder can be injected to bond the optical cable 100, the stripped optical fiber 101, the main body 1, the wire buckle 3 and the slide rail 2 into an integrated structure.

[0043] As an example of adhesive injection, an adhesive injection tool can be used to inject adhesive into the injection hole 40 to complete the adhesive injection operation. After the adhesive cures, the optical cable 100, the stripped optical fiber 101, the main body 1, the wire clip 3, and the slide rail 2 are bonded together to form an integrated structure. The injected adhesive can be a single-component adhesive, a two-component adhesive, or other multi-component adhesive.

[0044] As an example of adhesive injection, adhesive particles or powder can be injected into the injection hole 40 using an adhesive injection tool. The injection hole 40 is configured to allow the passage of adhesive particles or powder of a preset particle size, wherein the adhesive particles or powder are particles or powders that can be melted by microwave heating. After the adhesive particles or powder are injected, they are melted by microwave heating. The microwave is then removed, allowing the optical cable 100, the stripped optical fiber 101, the main body 1, the wire clip 3, and the slide rail 2 to bond into a single integrated structure. It is understood that the materials of the adhesive particles or powder, as well as the materials of the field connectors and optical fiber cables, can be carefully selected to ensure that the materials have different microwave resistance, thereby ensuring that the microwaves can heat and melt the injected adhesive particles or powder without affecting the field connectors and optical fiber cables themselves.

[0045] Specifically, microwave heating is selective; different substances absorb microwaves differently. Some colloidal materials, due to their molecular structure or composition, have a strong ability to absorb microwaves and can be heated by them. Meanwhile, field connectors and fiber optic cables can be made of materials with very weak or almost no microwave absorption, thus meeting the aforementioned requirements. For example, selecting colloids that are highly sensitive to microwave radiation can confine the generated heat to a specific area. Materials commonly used in fiber optic cables, such as silica and polymethyl methacrylate (PMMA), as well as cross-linked polystyrene used in some field connectors, almost completely penetrate microwaves without absorption, and microwaves do not significantly heat them.

[0046] For example, the aforementioned colloidal particles or powders are selected as hot melt adhesives that are solid at room temperature. There are many types of hot melt adhesives available; you can choose according to your needs.

[0047] EVA type: This is the most commonly used type, such as EVA-40, EVA-60, etc. The number usually represents the VA (vinyl acetate) content. Different contents result in different viscosity and flexibility.

[0048] Polyamide type (PA type): such as PA-12, PA-66, etc., have good high temperature resistance.

[0049] Polyurethane (PU) type: such as PU-100, PU-200, etc., with excellent elasticity and low-temperature resistance. This application prefers polyurethane type.

[0050] Polypropylene type (PP type): such as PP-50, PP-80, etc., have a good bonding effect on difficult-to-bond materials such as polypropylene.

[0051] As an example of adhesive dispensing, an adhesive pouch 41 can be provided in the dispensing hole 40. The adhesive pouch 41 contains adhesive, colloidal particles, or colloidal powder. The colloidal particles or powder are particles or powders that have been melted by microwave heating. In this example, the adhesive in the adhesive pouch 41 can be a single-component adhesive, or it can be one of the components of a multi-component adhesive. The remaining components can be injected using a dispensing tool. For example, a two-component adhesive may contain component A and component B, where component A is contained in the adhesive pouch 41, and component B is subsequently injected through the dispensing hole 40 using a dispensing tool.

[0052] As an example of adhesive injection, multiple adhesive pouches 41 can be provided in the injection hole 40, each pouch 41 containing one of the components of a multi-component adhesive. For example, a two-component adhesive may contain component A and component B, with component A contained in one pouch 41 and component B contained in another pouch 41. After puncturing the pouches 41, the components are mixed to achieve the purpose of bonding.

[0053] (2) In the second type, the glue injection part is a glue pack 41 that is pre-set on the side flip cover 4. The glue pack 41 contains glue, glue particles or glue powder. The glue particles or glue powder are particles or powders that are melted by microwave heating. The glue pack 41 is located on the inner wall of the side flip cover 4.

[0054] In this example, when only one adhesive pack 41 is provided, the adhesive inside the adhesive pack 41 is a single-component adhesive. When using a multi-component adhesive, multiple adhesive packs 41 can be provided, each containing one component of the multi-component adhesive. For example, a two-component adhesive contains component A and component B, where component A is contained in one adhesive pack 41 and component B is contained in another adhesive pack 41. After puncturing the adhesive packs 41, they are mixed to achieve the purpose of adhesion.

[0055] When the adhesive package 41 contains colloidal particles or powder, after the package 41 is punctured to allow the particles or powder to be injected, microwave heating is used to melt them. The microwave is then removed, allowing the optical cable 100, the stripped optical fiber 101, the main body 1, the wire clip 3, and the slide rail 2 to bond together as a single unit. Understandably, the materials of the colloidal particles or powder, as well as the materials of the field connectors and optical fiber cables, can be carefully selected to ensure they have different microwave resistance. This ensures that the microwaves can heat and melt the injected colloidal particles or powder without affecting the field connectors or the optical fiber cables themselves.

[0056] Compared to the first type where the glue injection hole 40 makes it easy to see the internal condition, in the second type, if the side cover 4 is made of a non-transparent material, it is not easy to see the internal condition, such as punctures or adhesions. Therefore, as a feasible solution, the side cover 4 can be made of a transparent material, whether in the first or second type, to facilitate the viewing of the internal condition.

[0057] Since the glue, adhesive particles, or adhesive powder inside the glue pouch 41 needs to leak out to be effective, the glue pouch 41 needs to be punctured. There are many ways to puncture it.

[0058] For example, the plastic bag 41 can be punctured when the side flip cover 4 is closed.

[0059] For example, the adhesive pack 41 can be broken when the side cover 4 is fastened to the main body 1.

[0060] For example, piercing elements can be provided on the slide rail 2, the wire buckle 3, and / or the side cover 4. When the side cover 4 is fastened, the piercing elements pierce the rubber package 41. For example, if the piercing element is provided on the slide rail 2 or the wire buckle 3 at the position corresponding to the rubber package 41, the piercing element can pierce the rubber package 41 when the side cover 4 is fastened to the main body 1. For example, if the piercing element is provided on the side cover 4, and the rubber package 41 is arranged in the glue injection hole 40, it can be partially located in the piercing path of the piercing element. When the side cover 4 is fastened to the main body 1, the piercing element can pierce the rubber package 41.

[0061] It is understandable that different methods can be used to place the aforementioned adhesive pack 41 on the inner wall of the side flap 4, or in the adhesive injection hole 40.

[0062] When the adhesive pack 41 is placed inside the glue injection hole 40, for example, adhesive tape can be attached to the adhesive pack 41 and pasted onto the outer wall of the side flap 4 to allow the adhesive pack 41 to enter the glue injection hole 40. Alternatively, for example, a support arm can be provided on the inner wall of the glue injection hole 40, and the adhesive pack 41 can be fixed to the support arm. The above are just two simple examples of different methods; in reality, there are many more methods to achieve the above objectives, which will not be listed here.

[0063] When the adhesive pad 41 is placed on the inner wall of the side-opening cover 4, for example, it can be glued to the inner wall of the side-opening cover 4. For example, an opening groove is provided on the inner wall of the side-opening cover 4, and the adhesive pad 41 is embedded in the opening groove. The above are just two simple examples of different methods. In fact, there are many more methods to achieve the above purpose, which will not be listed here.

[0064] See Figure 1 and Figure 5 As shown, the slide rail assembly also includes a fiber optic channel for the optical fiber 101 of the optical cable 100 to pass through and connect with the pre-embedded fiber in the ferrule assembly 5. The fiber optic channel is provided on the slide rail 2 and the wire buckle 3. The optical cable 100 is fixed on the wire buckle 3. The stripped optical fiber 101 of the optical cable 100 enters the ferrule assembly 5 from the fiber optic channel and connects with the pre-embedded fiber. The fiber optic channel includes a micro-bend redundant section 20 near the ferrule assembly 5 and an adhesive section 21 away from the ferrule assembly 5. The glue injection part is provided corresponding to the adhesive section 21. Since the glue injection part corresponds to the adhesive section 21, the optical fiber 101 and the optical cable 100 can be bonded and fixed to the slide rail assembly in the adhesive section 21 during glue injection.

[0065] Furthermore, due to the presence of a slightly bent redundant section 20, when the optical fiber 101 is connected to the pre-embedded fiber, the optical fiber 101 can be slightly bent within the slightly bent redundant section 20, thus having a certain length of excess length. The end of the optical fiber 101 connected to the pre-embedded fiber is denoted as the connection end A, and the end of the optical fiber 101 that is glued and fixed in the adhesive section 21 is denoted as the fixed end B. Since the fixed end B is fixed, even if the length between the connection end A and the fixed end B is shortened due to material shrinkage, the presence of the excess length of the optical fiber is sufficient to eliminate the effect of material shrinkage, thus ensuring the tight fit between the optical fiber 101 and the pre-embedded fiber.

[0066] Since the micro-bend redundant section 20 is connected to the adhesive section 21, and the adhesive has a certain degree of fluidity, or the colloid particles or powder have a certain degree of fluidity after melting, in order to prevent it from flowing from the adhesive section 21 to the micro-bend redundant section 20 to bond and fix the excess length, or even flowing to the mating end A, see [reference needed]. Figure 2As shown, this embodiment includes an anti-overflow adhesive section 6 to prevent adhesive from overflowing into the slightly curved redundant section 20. Specifically, the anti-overflow adhesive section 6 can be provided on the adhesive section 21 or the side flap 4.

[0067] For example, when installed on the side-flip cover 4, the anti-overflow adhesive part 6 can be inserted into the adhesive section 21 when the side-flip cover 4 is fastened to the main body 1. To prevent the anti-overflow adhesive part 6 from contacting the optical fiber 101 and thus avoiding damage to the optical fiber 101, the anti-overflow adhesive part 6 can be inserted into the adhesive section 21, and a small hole can be formed between the two for the optical fiber 101 to pass through. Alternatively, the anti-overflow adhesive part 6 can be made of an elastic material, such as rubber.

[0068] For example, when the adhesive section 21 is provided with an anti-overflow adhesive part 6, a small hole is reserved between the anti-overflow adhesive part 6 and the adhesive section 21 for the optical fiber 101 to pass through.

[0069] Furthermore, the puncture component is an overflow-proof adhesive part 6 used to prevent adhesive from overflowing into the micro-bend redundant section 20. This allows the overflow-proof adhesive part 6 to simultaneously perform the functions of puncturing and releasing overflow adhesive, achieving two functions with a single component and reducing the complexity of the connector.
