In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] Example, see Figures 1 to 7, an optical line terminal OLT device, including a PLT body, the PLT body includes a main frame 1 and a PLT processor module 2 arranged in the main frame 1, the main frame 1 is provided with an air outlet at the back, the PLT processor module 2 is a prior art, and will not be described in detail here;

[0035] The main frame 1 is composed of heat dissipation conduction frame bars 101 on both sides and a wiring frame bar 102 for wiring conduction at the front end. The heat dissipation conduction frame bar 101 is provided with heat dissipation holes 103 for cooling the PLT processor module 2 relative to the inner wall. The heat dissipation holes 103 are arranged on both sides to dissipate heat for the components on the PLT processor module 2 therein respectively.

[0036] A plurality of wiring terminals 3 are arranged on the wiring frame bar 102, and the wiring terminals 3 are composed of an access terminal, an output terminal, an optical fiber terminal and a distribution terminal. The OLT device is an important local-end device, which can be connected to the front-end (aggregation layer) switch with a network cable, converted into an optical signal, and interconnected with the optical splitter at the user end with a single optical fiber to realize the control of the user-end device ONU. Therefore, there are many connection settings of the connection terminal 3 according to the needs, which is the prior art. The two sides of the main frame 1 are connected with U-shaped wiring protection parts 4 by pressing the adjustment component;

[0037] Furthermore, the press-adjusting assembly includes reinforcing ribs 9 fixedly connected to both sides of the main frame 1, and telescopic openings 10 are opened at the ends of the reinforcing ribs 9. Telescopic insertion strips 11 are fixedly provided at both ends of the U-shaped wiring guard 4. The telescopic insertion strips 11 are inserted into the telescopic openings 10 and connected thereto through connecting springs.

[0038] It should be noted that the U-shaped wiring guard 4 has the effect of popping outward under the action of the telescopic plug 11, so that after wiring, each wiring terminal 3 can be shielded and protected by the U-shaped wiring guard 4, thereby ensuring reliable connection of the wiring terminal 3.

[0039] The side walls on both sides of the main frame 1 are provided with double-stage locking grooves 12 , and the inner wall of the U-shaped wiring protection member 4 is fixedly connected with a locking column 13 , which is movable in the double-stage locking grooves 12 .

[0040] It is worth noting that the double-speed locking groove 12 can lock the U-shaped wiring guard 4 when it is compressed when pressed. When the U-shaped wiring guard 4 is pressed again, the locking column 13 can be released. Its structure can refer to the structure of a mobile phone card slot, so as to facilitate use and wiring operations.

[0041] The U-shaped wiring protection member 4 is provided with an adapting penetration opening 5 adapted to the wiring terminal 3, and optical line traction members are provided on the U-shaped wiring protection member 4 on both sides of the adapting penetration opening 5;

[0042] Furthermore, the optical line traction member includes a vertical rectangular opening opened on the side wall of the U-shaped wiring protection member 4, the vertical rectangular opening is connected to two L-shaped abutment rods 14 arranged opposite to each other through an elastic member, and the ends of the L-shaped abutment rods 14 are fixedly connected to a semicircular clamping member 15;

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

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

[0045] It is worth noting that the guide slide 16 has a structure that is wide inside and narrow outside. The friction can be significantly reduced by setting the interference wheel 17. When the U-shaped wiring guard 4 moves outward, the L-shaped interference rod 14 will change from wide inside to narrow outside. During this process, the semicircular clamping member 15 will move inward, thereby effectively clamping the optical line conductor through the semicircular clamping member 15.

[0046] Furthermore, the elastic member includes a vertical guide column 18 fixedly connected in the vertical rectangular opening, the L-shaped resistance rod 14 is sleeved on the vertical guide column 18, and the two oppositely arranged L-shaped resistance rods 14 are connected to each other through a sleeve resistance spring.

[0047] The L-shaped resisting rods 14 can be pulled together by resisting springs, thereby ensuring the clamping effect of the semicircular clamping member 15 connected to the L-shaped resisting rod 14 on the wire.

[0048] A common cooling seat 6 for placing terminal equipment is arranged above the main frame 1, the common cooling seat 6 is connected to the PLT main body, the common cooling seat 6 is fixedly connected to the main frame 1, and a clamping and stabilizing member is arranged on the common cooling seat 6;

[0049] Furthermore, the clamping and stabilizing member includes side strips 19 fixedly connected to both sides of the common cooling placement seat 6, and rubber strips 20 are arranged on the side strips 19, and the rubber strips 20 can enhance the friction between the terminal device and the common cooling placement seat 6. A central clamping plate 21 is arranged in the middle of the common cooling placement seat 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 and heat dissipating assembly includes a heat dissipating cavity provided in the heat dissipating seat 7 , the heat dissipating cavity is connected with the heat dissipating conductive frame bar 101 through a conducting port penetrating the offset connecting rod 28 , and an air collecting fan 27 is provided at the heat dissipating cavity.

[0051] It should be noted that a rectangular connecting port penetrating the side wall is provided on the central clamping plate 21, and the inner side wall of the rectangular connecting port is slidably connected to the elastic slider 22. The elastic slider 22 applies pressure from the inclined clamping block 23 toward the inclined surface, which can achieve a resetting effect. Therefore, when no terminal device is placed, the inclined surface of the inclined clamping block 23 will not generate pressure, thereby ensuring that the adapter port 26 and the heat dissipation port 24 on the shielding heat dissipation plate 25 connected thereto are in a misaligned state, that is, when no terminal device is placed, the heat dissipation port 24 can be ensured to be in a sealed state.

[0052] The heat sink 7 is densely provided with heat dissipation openings 24 penetrating the side walls. The central clamping plate 21 is provided with two sets of relatively arranged shielding members for sealing the heat dissipation openings 24. The shielding members include a central cavity provided in the heat sink 7. A shielding heat dissipation plate 25 is movably provided inside the central cavity. The shielding heat dissipation plate 25 is provided with an adapter opening 26 adapted to the heat dissipation openings 24. The shielding heat dissipation plate 25 is fixedly connected to the inclined clamping block 23.

[0053] The shielding heat sink 25 is located in the central cavity and can move horizontally. When the inclined clamping block 23 is pressurized, it moves, causing the shielding heat sink 25 connected thereto to move, thereby causing the adapter port 26 and the heat dissipation port 24 that were originally sealed to each other in a misaligned state to move to the same position, thereby allowing the cold air in the PLT body to act on the terminal device connected thereto, thereby achieving a heat dissipation effect on the terminal device.

[0054] The two sides of the main frame 1 are connected to the heat sink 7 through the offset connecting rods 28. Both ends of the offset connecting rods 28 are provided with connecting shafts. The connecting shafts located on both sides of the offset connecting rods 28 are respectively connected to the heat sink 7 and the side walls of the reinforcement ribs 9.

[0055] The offset connecting rod 28 can be used to place the heat sink 7 close to and away from the PLT body, thereby meeting the use of the PLT body in different wiring states.

[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 conductive frame bar 101 through the wind collecting and heat dissipation components. The setting of the shock-absorbing seats 8 can satisfy the shock-absorbing effect of the PLT body.

[0057] When the present invention is in use, in response to the needs of the OLT device when in use, a U-shaped wiring protection piece 4 is provided at the wiring terminal 3 to protect the wiring terminal 3. After the wiring of the wiring terminal 3 is completed, the wiring portion is shielded and protected by the U-shaped wiring protection piece 4, and the semicircular clamping piece 15 provided at the wiring terminal 3 is simultaneously driven to move inward to effectively clamp the optical line conductor therein. When the optical line is subjected to tension, the pressure at the wiring terminal 3 can be borne by the semicircular clamping piece 15, thereby ensuring the wiring reliability of the wiring terminal 3.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
