Description

Technical Field

[0001] This utility model relates to the field of optical communication connector technology, and in particular to an improvement of an MPO connector and its push-pull sheath assembly. Background Technology

[0002] The MPO (Multi-fiber Push-On) connector is a multi-core fiber optic connector widely used in data centers, high-speed networks, and fiber optic communications. Its main advantage lies in its ability to achieve high-density fiber optic connections within limited space, making it an indispensable optical connection element in modern network cabling.

[0003] Existing MPO connectors typically have a sheath at the tail end for ease of grip and operation. However, in practical use, the sheath in traditional designs is usually a fixed connection or uses a simple snap-fit ​​sliding structure, which presents the following problems:

[0004] Inconvenient insertion and removal: Some MPO connectors have a housing design that is either fixed as a whole or loosely fitted, which cannot provide sufficient grip length and lever arm, making insertion and removal difficult, especially in high-density environments.

[0005] Lack of spring feedback: Traditional sheath structures lack a spring-back mechanism during push-pull operations, requiring users to manually return them to their original position, which affects operational efficiency;

[0006] Unstable connection: The mating structure between the sheath and the connector body is loose, which can easily cause displacement or wear during insertion and removal, affecting the stability of the connection;

[0007] Prone to fatigue damage: Due to the lack of an effective buffer mechanism, the mechanical impact during long-term insertion and removal is directly transmitted to the connector body or the fixing point of the sheath, which can easily cause structural fatigue or even damage.

[0008] To address these issues, some manufacturers have attempted to introduce push-pull structures or soft sheath components, but these still suffer from drawbacks such as complex installation, insufficient resilience, and poor reliability. Utility Model Content

[0009] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing an MPO connector with a push-pull sleeve. This MPO connector and its push-pull sleeve assembly are compact, easy to assemble, have elastic return capability, and offer good operating feel. They can improve the overall performance and service life of the MPO connection system.

[0010] To achieve the above objectives, the present invention adopts the following technical solution: it includes an outer shell 1, a connector body 2, a plug-in body 3, and a tail tube 4. The two sides of the connector body 2 are provided with return springs 5. The plug-in body 3 is inserted into the connector body 2, and the tail of the plug-in body 3 is inserted into the tail tube 4. The outer shell 1 is sleeved on the connector body 2.

[0011] The outer shell 1 has snap-fit ​​extension bodies 11 on both sides, and snap-fit ​​grooves 12 on the snap-fit ​​extension bodies 11. The tail tube 4 has a connector 41 at the front end, and snap-fit ​​protrusions 411 on both sides of the connector 41. The snap-fit ​​protrusions 411 snap into the snap-fit ​​grooves 12.

[0012] The plug body 3 has guides 31 on both sides, a baffle 32 at the bottom of the guides 31, and a reset spring 5 on the guides 31; a spring groove 24 corresponding to the guides 31 is provided on the inner side of the connector body 2.

[0013] The plug-in body 3 has a V-shaped structure and includes two receiving shells 33. The two receiving shells 33 are fixed on the bottom connector body base plate 34. A connecting post 35 is provided at the lower part of the body base plate 34. The connecting post 35 has a hollow structure and is inserted into the tail tube 4. A snap-fit ​​platform 331 is provided on the top outer side of the receiving shell 33.

[0014] The connector body 2 is provided with end face snap fasteners 23 on its upper and lower surfaces, and the end face snap fasteners 23 are snapped into the inside of the outer shell 1.

[0015] The tailpipe 4 is a flexible injection-molded protective sleeve, and the surface of the tailpipe 4 is provided with anti-slip ribs and ventilation grooves.

[0016] The working principle of this utility model is as follows: When the connector is not being plugged in or unplugged, the tail tube 4 is screwed and fixed to the connecting post 33 of the plug body 3 through the internal thread at its front end, and the whole is in a static state. The return spring 5 is in a naturally extended state, with one end of the return spring 5 fixed to the inner wall of the plug body 3, and the other end abutting against the guide part inside the connector body 2, providing continuous rebound force to the connector body 2.

[0017] In actual use, by holding the tail tube 4 and pushing the connector along the axial direction, the connector's front plug is driven to insert into the corresponding interface. During this process, the sheath slides relative to the connector body, causing the built-in return spring 5 to be compressed and store elastic energy. At the same time, the plug body 3 and the connector body 2 act as guides and limiters, preventing the tail tube from rotating or shifting. When the insertion and removal action is completed and the operator's hand pressure is released, the compressed return spring 5 releases its elastic potential energy, pushing the plug body 3 to automatically slide back to its original position along the axial direction, completing the automatic reset; the reset process is smooth and stable, without shaking or jamming.

[0018] The snap-fit ​​protrusion 411 of the tailpipe 4 securely fixes the connector body 2 and the insertion body 3 inside the housing 1 by snapping it into the housing 1. The connector body 2 and the insertion body 3, together with the spring, provide double support, effectively preventing problems such as loosening of the sheath and unstable connection caused by prolonged use or repeated insertion and removal. The continuous preload of the spring also enhances the structural closure of the overall connection system.

[0019] After adopting the above technical solution, the beneficial effects of this utility model are as follows: the spring assembly can achieve rapid rebound after the sheath is pushed and pulled, so that the sheath automatically returns to the initial position, which significantly improves the operating efficiency and convenience; the elastic force provided by the reset spring 5 can form flexible damping when the sheath is pushed and pulled, avoids hard sliding, effectively enhances the hand feedback, and allows the user to obtain a smooth and linear operating experience during use.

[0020] The return spring 5 creates a continuous preload between the plug body 3 and the connector body 2, effectively preventing the connector body from loosening, shifting, or even falling off, ensuring the connector remains stable and reliable even under high-frequency insertion / extraction, vibration, or compression environments. It not only enhances the functionality and user experience of the MPO connector but also achieves a balance between reliability and compactness in its structural design, giving it significant market application value.

[0027] See Figure 1-4 As shown, the technical solution adopted in this specific embodiment is as follows: It includes an outer shell 1, a connector body 2, a plug-in body 3, and a tail tube 4. Return springs 5 ​​are provided on both sides of the connector body 2. The plug-in body 3 is inserted into the connector body 2, and its tail is inserted into the tail tube 4. The outer shell 1 is sleeved on the connector body 2. Snap-fit ​​extensions 11 are provided on both sides of the outer shell 1, and snap-fit ​​grooves 12 are provided on the snap-fit ​​extensions 11. A connector 41 is provided at the front end of the tail tube 4, and snap-fit ​​protrusions 411 are provided on both sides of the connector 41, snapping into the snap-fit ​​grooves 12. Guide platforms 31 are provided on both sides of the plug-in body 3, and baffles 32 are provided at the bottom of the guide platforms 31. Return springs 5 ​​are provided on the guide platforms 31. A spring groove 24 corresponding to the guide platform 31 is provided on the inner side of the connector body 2. When the connector is not being plugged in or unplugged, the tail tube 4 is screwed and fixed to the connecting post 33 of the plug-in body 3 via its internal thread, and the entire assembly is in a static state. The return spring 5 is in its naturally extended state. One end of the return spring 5 is fixed to the inner wall of the plug body 3, and the other end abuts against the guide part inside the connector body 2, providing continuous rebound force to the connector body 2. The plug body 3 has a V-shaped structure and includes two receiving shells 33, which are fixed to the bottom connector body base plate 34. A connecting post 35 is provided at the lower part of the base plate 34. The connecting post 35 has a hollow structure and is inserted into the tail tube 4. A snap-fit ​​platform 331 is provided on the top outer side of the receiving shell 33. End face snap-fit ​​buckles 23 are respectively provided on the upper and lower surfaces of the connector body 2, and the end face snap-fit ​​buckles 23 are snapped into the inside of the outer shell 1. The tail tube 4 is a flexible injection-molded protective sleeve, and the surface of the tail tube 4 is provided with anti-slip ribs and ventilation grooves.

[0028] In practical use, this embodiment involves holding the tail tube 4 and pushing the connector along its axial direction to insert the connector's front plug into the corresponding interface. During this process, the sheath slides relative to the connector body, compressing the built-in return spring 5 and storing elastic energy. Simultaneously, the plug body 3 and connector body 2 act as guides and limiters, preventing the tail tube from rotating or shifting. Once the insertion / removal action is completed and the operator's hand pressure is released, the compressed return spring 5 releases its elastic potential energy, pushing the plug body 3 to automatically slide back to its original position along its axial direction, completing the automatic reset. The reset process is smooth and stable, without any shaking or jamming.

[0029] The snap-fit ​​protrusion 411 of the tailpipe 4 securely fixes the connector body 2 and the insertion body 3 inside the housing 1 by snapping it into the housing 1. The connector body 2 and the insertion body 3, together with the spring, provide double support, effectively preventing problems such as loosening of the sheath and unstable connection caused by prolonged use or repeated insertion and removal. The continuous preload of the spring also enhances the structural closure of the overall connection system.

[0030] After adopting the above technical solution, the beneficial effects of this utility model are as follows: the spring assembly can achieve rapid rebound after the sheath is pushed and pulled, so that the sheath automatically returns to the initial position, which significantly improves the operating efficiency and convenience; the elastic force provided by the reset spring 5 can form flexible damping when the sheath is pushed and pulled, avoids hard sliding, effectively enhances the hand feedback, and allows the user to obtain a smooth and linear operating experience during use.

[0031] The return spring 5 creates a continuous preload between the plug body 3 and the connector body 2, effectively preventing the connector body from loosening, shifting, or even falling off, ensuring the connector remains stable and reliable even under high-frequency insertion / extraction, vibration, or compression environments. It not only enhances the functionality and user experience of the MPO connector but also achieves a balance between reliability and compactness in its structural design, giving it significant market application value.
