Description

Technical Field

[0001] This utility model relates to the field of OLT equipment, specifically an OLT equipment with a sealing structure. Background Technology

[0002] OLT equipment is an important central office device that can be connected to the front-end (aggregation layer) switch via network cable to convert it into optical signals. It is then interconnected with the user-end splitter via a single optical fiber, enabling functions such as control, management, and ranging of the user-end ONU. It is a common type of optoelectronic integrated equipment.

[0003] Traditional OLT devices have unconnected plugs exposed on the outside during use, causing a large amount of dust to accumulate inside the connection sockets, which can easily damage them. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an OLT device with a sealed structure to solve the technical problem that when the current OLT device is in use, the unconnected plug is directly exposed on the outside, so that a lot of dust will be absorbed inside the connection hole, which will easily cause damage to the connection hole.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: An OLT device with a sealed structure is designed, including an OLT device body. Multiple wiring holes are provided at the rear end of the OLT device body. Mounting plates are installed on both sides of the OLT device body near the wiring holes. A first support plate and a second support plate are provided between the two mounting plates. A rectangular slot is opened at the end of the first support plate near the second support plate. A semi-circular slot is opened at the opposite end of the second support plate to the rectangular slot. Springs are connected to both sides between the first support plate and the second support plate. A sliding groove is opened on the first support plate, and multiple sliders are provided in the sliding groove. A moving plate is connected to each of the multiple sliders. A telescopic mechanism is provided on the moving plate. A rubber cap is connected to one end of the telescopic mechanism, and the rubber cap is adapted to the wiring holes.

[0006] Preferably, the telescopic mechanism includes a connecting cylinder and a connecting rod, the connecting cylinder being connected to a rubber cover, the connecting rod being connected to a movable plate, and the connecting cylinder being slidably sleeved on the outside of the connecting rod.

[0007] Preferably, the mounting plate has a limiting groove, and each limiting groove is slidably connected to a limiting block, which is connected to the second support plate.

[0008] Preferably, a fixing plate is connected to one end of each of the two mounting plates, the mounting plate and the fixing plate are connected in an L-shape, a bolt passes through the fixing plate, and the bolt is threaded to the surface of the OLT equipment body.

[0009] Preferably, the outer radius of the connecting rod is smaller than the inner radius of the semicircular groove, and the outer diameter of the connecting rod is smaller than the distance between the first support plate and the second support plate.

[0010] Preferably, both the groove and the slider are T-shaped, and the slider is slidably connected within the groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model combines a first support plate, a second support plate, a semi-circular groove, a spring, a movable plate, a sliding groove, a slider, a telescopic mechanism, a rubber cover, and a rectangular slot to seal unused wiring holes, preventing dust from entering. It also limits the connection of wires connected in the wiring holes, effectively preventing poor contact between the wire joint and the wiring hole caused by wire traction.

[0013] 2. This utility model combines a limiting groove and a limiting block. The limiting block guides the movement of the second support plate within the limiting groove, thereby further improving the stability of the up-and-down movement of the second support plate. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] Example 1: An OLT device with a sealed structure, see [link to example]. Figures 1 to 4The device includes an OLT device body 1. The rear end of the OLT device body 1 has multiple wiring holes 11. Mounting plates 2 are installed on both sides of the OLT device body 1 near the wiring holes 11. A first support plate 3 and a second support plate 4 are positioned between the two mounting plates 2. A rectangular slot 31 is formed at the end of the first support plate 3 near the second support plate 4. Semicircular slots 5 are formed at the opposite ends of the second support plate 4 and the rectangular slot 31. Springs 7 are connected to both sides between the first support plate 3 and the second support plate 4. A sliding groove 32 is formed on the first support plate 3. Multiple sliders 33 are arranged within the sliding groove 32. Both the sliding groove 32 and the sliders 33 are T-shaped, and the sliders 33 are slidably connected within the sliding groove 32. Each of the multiple sliders 33 is connected to a movable plate 6, and the movable plate 6 is provided with a telescopic mechanism. One end of the telescopic mechanism is connected to a rubber cover 61. The telescopic mechanism includes a connecting cylinder 63 and a connecting rod 62. The connecting cylinder 63 is connected to the rubber cover 61, and the connecting rod 62 is connected to the movable plate 6. The connecting cylinder 63 is slidably sleeved on the outside of the connecting rod 62, and the rubber cover 61 is adapted to the wiring hole 11. During operation, the second support plate 4 is pulled upward to stretch the spring 7. Then, the connector to be connected to the wiring hole 11 is passed between the first support plate 3 and the second support plate 4 and inserted into the wiring hole 11. Then, the connecting wire is aligned with the semicircular groove 5, thereby pulling the second support plate 63 by the tension of the spring 7. The support plate 4 moves closer to the first support plate 3, thereby cooperating with the semi-circular groove 5 to limit the connection line. The tension of the spring 7, combined with the friction between the connection line and the semi-circular groove 5, limits the connection line. Then, the slider 33 moves within the groove 32 to align the rubber cap 61 with the unconnected wiring hole 11. The connecting cylinder 63 then slides into the connecting rod 62, moving the rubber cap 61 into the wiring hole 11 to seal it, preventing dust from entering and damaging the wiring hole 11 when not in use. Excess rubber caps 61 are then adjusted to the sides to seal unused wiring holes 11, preventing dust from entering and limiting the connection line connected to the wiring hole 11, effectively preventing the connection line from being pulled. This leads to poor contact between the connector of the connecting cable and the wiring hole 11. When the OLT device body 1 is in use, from the downlink direction, the OLT receives electrical signals from the upper-layer network (such as the core network). These signals contain a lot of information such as Internet data and voice call data. The OLT converts these electrical signals into optical signals, and then sends them to each ONU (Optical Network Unit) in the form of broadcast through the optical splitter. In the uplink direction, the OLT receives optical signals sent by each ONU. Because different ONUs share optical fiber lines, the OLT must use time division multiplexing and other technologies to distinguish the signals of these different ONUs, and then convert the optical signals into electrical signals, and then transmit the data to the upper-layer network equipment, thereby realizing data interaction between the user end and the network end.

[0021] For details, see Figure 4 The mounting plate 2 has a limiting groove 23, and each limiting groove 23 is slidably connected to a limiting block 24. The limiting block 24 is connected to the second support plate 4. By guiding the movement of the limiting block 24 within the limiting groove 23, the movement of the second support plate 4 can be guided, thereby further improving the stability of the up and down movement of the second support plate 4.

[0022] Further, see Figure 2 Each of the two mounting plates 2 has a fixing plate 21 connected to one end of its opposite side. The mounting plate 2 and the fixing plate 21 are connected in an L-shape. A bolt 22 passes through the fixing plate 21 and is threaded to the surface of the OLT equipment body 1. The fixing plate 21 can be easily disassembled by turning the bolt 22, which further facilitates the installation of the device on the OLT equipment body or the removal of the device from the OLT equipment body.

[0023] It is worth noting that, see Figure 1 The outer radius of the connecting rod 62 is smaller than the inner radius of the semicircular groove 5, and the outer diameter of the connecting rod 62 is smaller than the distance between the first support plate 3 and the second support plate 4. This is to ensure that the connecting rod 62 connected to the unused sealing cover does not affect the movement of the second support plate and the semicircular groove 5 to snap the connecting line.
