Description

Technical Field

[0001] This invention relates to the field of information and communication equipment technology, and in particular to an optical line terminal (OLT) device. Background Technology

[0002] An OLT is an important central office device that can be connected to a front-end (aggregation layer) switch via a network cable to convert signals into optical signals and interconnect with the user-end splitter via a single optical fiber. It enables control, management, and ranging of the user-end device ONU. Like the ONU device, it is an optoelectronic integrated device.

[0003] The characteristics of OLTs often require the use of front-end and back-end devices, resulting in the need for multiple wires at their connection points. Current OLT devices primarily protect the terminals using built-in snap-fit ​​structures. However, during optical transmission, proper wiring is crucial for signal delivery. Simple snap-fit ​​structures cannot effectively guarantee the reliability of OLT wiring. Furthermore, after wiring, front-end and back-end devices cannot be effectively integrated with the OLT, and simply placing them on top can negatively impact heat dissipation. Moreover, the disorganized installation of numerous OLT devices in a database can disrupt overall device consistency and hinder future maintenance. Therefore, this paper proposes an optical line terminal OLT device. Summary of the Invention

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An optical line terminal (OLT) device includes a PLT body, which includes a main frame and a PLT processor module disposed within the main frame.

The heat dissipation and conduction frame strips have heat dissipation holes on their inner sidewalls to cool the PLT processor module.

[0007] The wiring frame is provided with multiple wiring terminals, each consisting of an access terminal, an output terminal, an optical fiber terminal, and a wiring terminal. The two sides of the main frame are connected to U-shaped wiring protection components via a pressing adjustment assembly. The U-shaped wiring protection components have an adapter penetration opening that matches the wiring terminal. Optical line traction components are provided on both sides of the adapter penetration opening of the U-shaped wiring protection components.

[0008] A common cooling placement base for placing terminal equipment is provided on the upper part of the main frame. The common cooling placement base is connected to the PLT main body and is provided with clamping and stabilizing components.

[0009] The main frame is connected to heat sinks on both sides by offset connecting rods. Shock-absorbing seats are provided at the four corners of the heat sinks. The heat sinks are connected to the heat dissipation conduction frame strips through the air collection and heat dissipation components.

[0010] Preferably, the pressing adjustment component includes reinforcing ribs fixedly connected to both sides of the main frame, the ends of the reinforcing ribs are provided with telescopic openings, and both ends of the U-shaped wiring protection component are fixedly provided with telescopic inserts, which are inserted into the telescopic openings and connected to them by connecting springs.

[0011] Preferably, the main frame has double-locking grooves on both sides, and the U-shaped wiring protection component has a locking post fixedly connected to its inner side wall, which moves within the double-locking groove.

[0012] Preferably, the optical line traction component includes a vertical rectangular opening on the side wall of the U-shaped wiring protection component, and the vertical rectangular opening is connected by an elastic element to two L-shaped abutment rods arranged opposite each other, and a semi-circular clamping component is fixedly connected to the end of the L-shaped abutment rod;

[0013] Guide slides are fixedly connected to both sides of the terminal block, and the end of the L-shaped abutment rod is provided with an abutment wheel that abuts against the guide slide.

[0014] Preferably, the elastic element includes a vertical guide post fixedly connected within a vertical rectangular opening, an L-shaped abutment rod sleeved on the vertical guide post, and two L-shaped abutment rods arranged opposite to each other are connected to each other by a sleeved abutment spring.

[0015] Preferably, the clamping and stabilizing component includes side strips fixedly connected to both sides of the co-cooling placement base, the side strips are provided with rubber strips, the co-cooling placement base is provided with a central clamping plate in the middle, and the side wall of the central clamping plate is connected to an inclined clamping block through an elastic slider;

[0016] The heat sink is densely covered with heat dissipation vents that penetrate the side wall, and the central clamp is provided with two sets of opposing shielding members to seal the heat dissipation vents.

[0017] Preferably, the shielding component includes a central cavity formed within the heat sink, a shielding heat sink plate is movably disposed inside the central cavity, the shielding heat sink plate has an adapter opening adapted to the heat sink opening, and the shielding heat sink plate is fixedly connected to the inclined clamping block.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. This invention addresses the needs of OLT equipment usage by providing a U-shaped connector protection at the connector end. After wiring, the connector shields the wiring area and simultaneously moves a semi-circular clamp at the connector end inward to effectively clamp the optical cable.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] Example, refer to Figures 1 to 7An optical line terminal (OLT) device includes a PLT main body. The PLT main body includes a main frame 1 and a PLT processor module 2 disposed in the main frame 1. An air vent is provided on the back of the main frame 1. The PLT processor module 2 is prior art and will not be described in detail here.

[0035] The main frame 1 is composed of heat dissipation and conduction frame strips 101 on both sides and wiring frame strip 102 at the front end for wiring conduction. The heat dissipation and conduction frame strips 101 have heat dissipation holes 103 on the inner side wall to cool the PLT processor module 2. The heat dissipation holes 103 are located on both sides to dissipate heat from the components in the PLT processor module 2.

[0036] The wiring frame 102 is provided with multiple wiring terminals 3. The wiring terminals 3 consist of an access terminal, an output terminal, an optical fiber terminal, and a distribution terminal. The OLT device is an important central office device. It can be connected to the front-end (aggregation layer) switch with a network cable, convert it into an optical signal, and interconnect it with the optical splitter at the user end with a single optical fiber to realize the control of the user end device ONU. Therefore, the connection settings of its wiring terminals 3 can vary as needed. This is the existing technology. The two sides of the main frame 1 are connected with U-shaped wiring protection components 4 through the pressing adjustment components.

[0037] Furthermore, the pressing adjustment component includes reinforcing ribs 9 fixedly connected to both sides of the main frame 1. The ends of the reinforcing ribs 9 are provided with telescopic openings 10. Both ends of the U-shaped wiring protection component 4 are fixedly provided with telescopic inserts 11. The telescopic inserts 11 are inserted into the telescopic openings 10 and connected to them through connecting springs.

[0038] It should be noted that the U-shaped wiring protection component 4 has an outward pop-out effect under the action of the telescopic insert 11. This allows the U-shaped wiring protection component 4 to shield and protect each terminal 3 after wiring, thereby ensuring the reliable connection of the terminal 3.

[0039] The main frame 1 has double-locking grooves 12 on both sides of the side wall. The U-shaped wiring protection component 4 has a locking post 13 fixedly connected to the inner side wall. The locking post 13 moves within the double-locking groove 12.

[0040] It is worth noting that the dual-position locking groove 12 can lock when the U-shaped wiring protection piece 4 is compressed, and can release the locking post 13 when the U-shaped wiring protection piece 4 is pressed again. Its structure can be referenced from the structure of a mobile phone card slot, which facilitates use and wiring operations.

[0041] The U-shaped wiring protection component 4 has an adapter penetration port 5 that is compatible with the wiring terminal 3. Optical line traction components are provided on both sides of the U-shaped wiring protection component 4 located at the adapter penetration port 5.

[0042] Furthermore, the optical line traction component includes a vertical rectangular opening on the side wall of the U-shaped wiring protection component 4. The vertical rectangular opening is connected by an elastic element to two L-shaped abutment rods 14 that are arranged opposite each other. The ends of the L-shaped abutment rods 14 are fixedly connected to a semi-circular clamping component 15.

[0043] The inner diameter of the semi-circular clamping member 15 located at different terminals 3 is adapted to the diameter of the optical line, which can meet the clamping of different optical lines and ensure that the optical line will not be bent at the connection point, thereby ensuring the conduction effect of the optical signal.

[0044] Both sides of the terminal 3 are fixedly connected to guide slides 16, and the end of the L-shaped abutment rod 14 is provided with an abutment wheel 17 that abuts against the guide slides 16.

[0045] It is worth noting that the guide slide 16 has a structure that is wider on the inside and narrower on the outside. By setting the abutment wheel 17, the friction can be significantly reduced. When the U-shaped wiring protection component 4 moves outward, the L-shaped abutment rod 14 will move from wider on the inside to narrower on the outside. During this process, the semi-circular clamping component 15 will move inward, thereby effectively clamping the optical line conductor through the semi-circular clamping component 15.

[0046] Furthermore, the elastic element includes a vertical guide post 18 fixedly connected in a vertical rectangular opening, an L-shaped abutment rod 14 sleeved on the vertical guide post 18, and two L-shaped abutment rods 14 arranged opposite to each other are connected to each other by abutment springs.

[0047] The L-shaped contact rods 14 are connected by contact springs, which allow them to pull against each other and ensure the clamping effect of the semi-circular clamping member 15 connected to the L-shaped contact rods 14 on the wire.

[0048] A common cooling placement seat 6 for placing terminal equipment is provided on the upper part of the main frame 1. The common cooling placement seat 6 is connected to the PLT main body and fixedly connected to the main frame 1. A clamping and stabilizing component is provided on the common cooling placement seat 6.

[0049] Furthermore, the clamping and stabilizing components include side strips 19 fixedly connected to both sides of the co-cooling placement base 6, and rubber strips 20 are provided on the side strips 19. The rubber strips 20 can enhance the friction between the rubber strips and the terminal equipment. A central clamping plate 21 is provided in the middle of the co-cooling placement base 6, and the side wall of the central clamping plate 21 is connected to an inclined clamping block 23 through an elastic slider 22.

[0050] The air-collecting heat dissipation component includes a heat dissipation cavity opened in the heat dissipation base 7. The heat dissipation cavity is connected to the heat dissipation conduction frame 101 through the conduction port of the biased connecting rod 28. An air-collecting fan 27 is provided at the heat dissipation cavity.

[0051] It should be noted that the central clamping plate 21 has a rectangular connection port that penetrates the side wall. The inner side wall of the rectangular connection port is slidably connected to the elastic slider 22. The elastic slider 22 applies pressure to the inclined clamping block 23 towards the inclined surface, which can achieve the effect of resetting. Therefore, when no terminal device is placed, the inclined surface of the inclined clamping block 23 will not generate pressure. Thus, it can be ensured that the adapter port 26 on the shielding heat dissipation plate 25 connected to it is misaligned with the heat dissipation port 24. That is, when no terminal device is placed, it can be ensured that the heat dissipation port 24 is in a sealed state.

[0052] The heat sink 7 is densely covered with heat dissipation vents 24 that penetrate the side wall. The central clamping plate 21 is provided with two sets of opposing shielding members to seal the heat dissipation vents 24. The shielding members include a central cavity opened in the heat sink 7. A shielding heat dissipation plate 25 is movably arranged inside the central cavity. The shielding heat dissipation plate 25 is provided with an adapter port 26 that matches the heat dissipation vents 24. The shielding heat dissipation plate 25 is fixedly connected to the inclined clamping block 23.

[0053] The shielding heat dissipation plate 25 is located in the central cavity and can move horizontally. When the inclined clamping block 23 is pressed, it will move, causing the shielding heat dissipation plate 25 connected to it to move. This causes the adapter port 26 and the heat dissipation port 24, which were originally in a misaligned state and sealed to each other, to move to the same position, thereby enabling the cold air in the PLT body to be applied to the terminal equipment connected to it, and achieving the heat dissipation effect on the terminal equipment.

[0054] The main frame 1 is connected to heat sinks 7 on both sides by offset connecting rods 28. Both ends of the offset connecting rods 28 are provided with connecting shafts, and the connecting shafts on both sides of the offset connecting rods 28 are connected to the heat sinks 7 and the side walls of the reinforcing ribs 9, respectively.

[0055] The offset connecting rod 28 allows the heat sink 7 to be brought close to and from the PLT body, thus satisfying the use of the PLT body under different wiring conditions.

[0056] Shock-absorbing seats 8 are provided at the four corners of the heat sink 7. The heat sink 7 is connected to the heat dissipation conduction frame 101 through the air collection and heat dissipation component. The setting of the shock-absorbing seats 8 can meet the shock absorption effect of the PLT body.

[0057] When used, this invention addresses the needs of OLT equipment by providing a U-shaped wiring protection component 4 to the wiring terminal 3. After wiring is completed at the wiring terminal 3, the wiring area is shielded and protected by the U-shaped wiring protection component 4. Simultaneously, the semi-circular clamping component 15 located at the wiring terminal 3 moves inward to effectively clamp the optical line conductor within it. When the optical line is subjected to tension, the semi-circular clamping component 15 can bear the pressure at the wiring terminal 3, ensuring the reliability of the wiring at the wiring terminal 3.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
