Description

Technical Field

[0001] This utility model relates to the field of fiber optic connectors, and in particular to an LC type fiber optic connector with dustproof function. Background Technology

[0002] LC type fiber optic connectors are miniaturized connectors widely used in the field of fiber optic communication. They are small in size and light in weight, which makes them perform well in high-density installation environments, effectively saving space and increasing the port density of equipment such as fiber optic distribution frames.

[0003] However, while some existing conventional LC fiber optic connectors have simple structures and wide applications, they do not have dustproof structures. This means that when used in dusty outdoor environments, they are affected by dust, leading to increased transmission loss and affecting the lifespan of the fiber optic connector, making them impractical. Therefore, a dustproof LC fiber optic connector is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an LC type fiber optic connector with dustproof function, which aims to improve the existing technology. However, some conventional LC type fiber optic connectors, although simple in structure and widely used, do not have a dustproof structure. This leads to the problem that when used in dusty outdoor environments, they will be affected by dust, resulting in increased transmission loss.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an LC type fiber optic connector with dustproof function, including a front frame, the front frame being made of silicone material, a rear frame being installed on the rear side of the front frame, an adapter being inserted into the front side of the front frame, a retaining strip being provided on the inner wall of the front frame, a retaining groove being opened on the inner wall of the adapter, the retaining groove being movably connected to the retaining strip, a ferrule being passed through and fixedly connected to the middle of the front frame, and a sleeve being fixedly connected inside the adapter, the ferrule being inserted into the sleeve.

[0006] As a further description of the above technical solution: A tail shank is installed in the middle of the rear frame, and the insert is connected to the tail shank through it.

[0007] As a further description of the above technical solution: A tail sleeve is installed on the rear side of the rear frame.

[0008] As a further description of the above technical solution: A retaining ring is installed between the rear frame and the tail sleeve.

[0009] As a further description of the above technical solution: A spring is installed between the ferrule and the tailstock.

[0010] As a further description of the above technical solution: A white tube is installed between the ferrule and the tailstock. The white tube is sleeved on the rear of the tailstock and inserted into the middle of the ferrule.

[0011] This utility model has the following beneficial effects: 1. In this utility model, the front frame is made of silicone material. Utilizing the sealing properties of silicone, it can effectively prevent dust from entering the connector, thereby reducing the corrosion of core components such as the ferrule and sleeve by dust from the source. At the same time, the interference of the slot and the strip can ensure the tightness of the connection between the front frame and the adapter, thereby improving the dustproof effect of the connector.

[0014] 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.

[0015] Reference Figure 1 - Figure 3This utility model provides an embodiment of an LC-type fiber optic connector with dustproof function, including a front frame 1. The front frame 1 is made of silicone material. The silicone material, which has high elasticity and high sealing performance, can fill the connection gap through its own flexible properties, thereby preventing dust. A rear frame 2 is installed on the rear side of the front frame 1. After the front frame 1 and the rear frame 2 are mated, they form a complete shell protective structure, which can effectively prevent external impurities from entering the internal component area. An adapter 9 is inserted into the front side of the front frame 1. A ferrule 3 is connected through and fixedly connected to the middle of the front frame 1. A sleeve 10 is fixedly connected inside the adapter 9. The ferrule 3 is inserted into the sleeve 10. When the ferrule 3 and the sleeve 10 are inserted, they can achieve precise alignment, ensure efficient coupling of the fiber core diameter, and thus maintain a stable signal transmission effect.

[0016] To further enhance the stability and sealing of the connection between the front frame 1 and the adapter 9, a retaining strip 11 is provided on the inner wall of the front frame 1. The retaining strip 11 and the front frame 1 are integrally formed and have a certain elastic deformation capability. A retaining groove 91 is provided on the inner wall of the adapter 9. The retaining groove 91 is movably connected to the retaining strip 11. When the adapter 9 is inserted into the front frame 1, the retaining strip 11 can be elastically inserted into the retaining groove 91 to form a bidirectional limiting fixation. This not only facilitates the quick assembly and subsequent disassembly and maintenance of both, but also further reduces the connection gap, strengthens the dustproof sealing effect of the front end, and prevents dust from entering the interior from the joint gap.

[0017] Furthermore, a tail shank 4 is installed in the middle of the rear frame 2. This tail shank is a ferrule tail shank. The ferrule 3 and the tail shank 4 are connected through and fixedly connected. A tail sleeve 8 is installed on the rear side of the rear frame 2. The tail sleeve 8 can be made of flexible rubber. When the external optical cable is inserted into the tail sleeve 8, the tail sleeve 8 can tightly wrap the outer wall of the optical cable through its own elasticity, forming a dustproof and waterproof seal at the rear end. At the same time, it can buffer the tensile force on the optical cable and prevent the connection between the optical cable and the connector from being damaged due to excessive force. A bundle ring 7 is installed between the rear frame 2 and the tail sleeve 8. A spring 5 is installed between the bundle ring 7 and the tail shank 4. A white tube 6 is installed between the bundle ring 7 and the tail shank 4. The white tube 6 is sleeved on the rear of the tail shank 4 and inserted into the middle of the bundle ring 7. The front frame 1, rear frame 2, ferrule 3, tail shank 4, spring 5, white tube 6, bundle ring 7, and tail sleeve 8 together form a dustproof LC type optical fiber connector.

[0018] Working principle: When the dustproof LC type fiber optic connector is mated with the adapter 9, the sleeve 10 inside the adapter 9 is responsible for the precise mating of the two to maintain normal communication. In order to achieve dustproof, the front frame 1 is made of highly elastic and highly sealing silicone material. Its own flexibility can effectively fill the connection gap, thereby achieving the dustproof effect. Because silicone is relatively soft, it can ensure a tight fit while also ensuring the self-adaptability of the ferrule 3, ensuring that the connection data is not affected. A certain amount of interference is designed between the front frame 1 and the adapter 9, namely the retaining strip 11 and the retaining groove 91, so as to ensure that the front frame 1 and the adapter 9 can fit tightly, preventing dust from entering the connector and ensuring normal communication.

[0019] 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.
