Description

Technical Field

[0001] The invention relates to the technical field of optoelectronic communication, in particular to an optical cable branching device supporting an electrical switching function. Background Art

[0002] With the continuous development of broadband demand, especially in the construction of fiber-to-the-home projects, in order to make full use of fiber bandwidth resources to reduce the number of outgoing optical cables and reduce the port occupancy of line-side equipment, passive splitters will play a vital role in fiber access networks. Passive optical networks are the most attractive technology to solve access networks and realize FTTx. The so-called "passive" means that the optical distribution network does not contain any active electronic devices and power supplies, and is entirely composed of passive devices such as optical splitters.

[0003] During the use of the passive optical cable splitter, the optical module and the electrical module inside it generate heat. In order to maintain the normal use of the equipment, it is usually necessary to open a ventilation groove on the outer shell of the splitter to increase the heat exchange between the inside of the splitter and the outside world and dissipate the heat generated by the optical module and the electrical module. In order to prevent dust from entering the splitter through the ventilation groove and affecting the use of the optical and electrical modules, a dustproof net is generally provided in the ventilation groove. However, after long-term use, dust easily adheres to the surface of the dustproof net, causing the mesh to be blocked, affecting the heat dissipation efficiency of the splitter. Although there is a dustproof net, smaller dust particles will still pass through the mesh and enter the splitter, affecting the normal use of the optical and electrical modules inside the splitter.

The nitrogen inside the conveying pipe 520a is transported to the slide plate 530 through the first hose 520a-1, and is sprayed from the air nozzle 530a to the interior of the upper shell 110 and the lower shell 120, thereby pressing the upper shell The interior of the upper shell 110 and the lower shell 120 is purged with nitrogen to blow away the dust attached to the surface of the optical module 110a-1 and the electrical module 120a-1 inside the upper shell 110 and the lower shell 120, and when the mounting frame 310 moves forward to the point where the third one-way rack 310d is meshed with the first one-way gear 140, the third one-way rack 310d is driven forward as the mounting frame 310 moves forward, and the third one-way rack 310d drives the first one-way gear 140 and the second bevel gear 140a to rotate, and the second bevel gear 140a rotates and drives the first bevel gear 120d-2 and the first reciprocating threaded rod 120d-1 to rotate, and the screw rod structure is used to push the slide plate 530 to drive the air nozzle 530a to move a certain distance, and reciprocate in sequence, and nitrogen is purged at different positions inside the upper shell 110 and the lower shell 120 after each movement of the slide plate 530.

[0035] Combination Figure 1-Figure 7In the present embodiment, an optical cable splitter supporting an electrical switching function is used. During use, the second reciprocating threaded rod 220 is driven to rotate by starting the motor 230, and the two mounting brackets 310 are pushed to move forward and backward along the outside of the upper shell 110 and the lower shell 120. Each time the mounting bracket 310 moves backward, the first one-way rack 110c drives the upper fan blades 330 to rotate to generate airflow, which dissipates heat inside the upper shell 110 and the lower shell 120. At the same time, the cleaning component 410 and the dust collection component 420 above clean the dust on the surface of the dustproof net inside the first air permeable groove 110b. Each time the mounting bracket 310 moves forward, the second one-way rack 120c drives the lower fan blades 330 to rotate to generate airflow, which dissipates heat inside the upper shell 110 and the lower shell 120. Heat, at the same time, the cleaning component 410 and the dust suction component 420 below clean the dust on the surface of the dustproof net inside the second air permeable groove 120b. Each time the mounting frame 310 moves back to its position, the flat rack 310c drives the flat gear 510b and the threaded rod 510c to rotate, pushing the conveying part 520b to move outside the conveying pipe 520a, and drawing the external nitrogen into the conveying pipe 520a. When the mounting frame 310 and the flat rack 310c move forward, they drive the conveying part 520b to move inside the conveying pipe 520a, and deliver the nitrogen to the air nozzle 530a and spray it into the upper shell 110 and the lower shell 120, so as to blow away the dust attached to the surface of the optical module 110a-1 and the electrical module 120a-1 inside the upper shell 110 and the lower shell 120.
