[0041] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0042] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0043] See also Figure 1-4 The first embodiment provides an SDH optical transmission device, which mainly includes: a housing 100, an extension component 200, a transmission component 300 and a control component 400, etc.

[0044] like Figure 1 , Figure 2As shown in , the housing 100 is roughly in the shape of a horizontal rectangular parallelepiped, and in this embodiment, it serves as the main outer structure, and other components and various circuit elements are arranged inside it. A hexagonal opening 103 is arranged in the middle of the upper surface of the housing 100, and the opening 103 has a certain depth, which is used to accommodate the expansion component 200 and facilitate its up and down movement. At the same time, a rectangular first slide 101 and a second slide 102 are arranged on both sides of the opening 103, and the first slide 101 and the second slide 102 are arranged in the vertical direction. In addition, since the wires are more flexible, the interfaces for connecting the wires need to be centrally designed. A device interface board 110 for connecting other devices and a power port panel 120 for connecting to the power supply are installed on the same surface of the outer side wall of the housing 100. At the same time, in order to facilitate the fixing of the position of the housing 100, a fixing plate 130 with fixing holes is also arranged at the bottom of the two sides of the housing 100.

[0045] like Figure 1-Figure 4 As shown in the figure, the expansion component 200 is movably arranged above the housing 100, and has a plurality of sockets and expansion slots thereon, which are used to expand the number of interfaces of the SDH optical transmission device of this embodiment, and facilitate the access of optical fiber lines and the installation of expansion boards. The expansion component 200 is mainly composed of a plug-in body 230 and a first slider 210 and a second slider 220 on both sides of the plug-in body 230. The plug-in body 230 is in the shape of a hexagonal prism adapted to the opening 103, arranged at the lower part of the expansion component 200, and slidably embedded in the opening 103, and an optical fiber line is arranged at the bottom thereof to connect various circuit elements in the housing 100; two socket panels 232 and four expansion panels 234 are arranged on the side wall of the plug-in body 230, and each of the socket panels 232 and the expansion panel 234 is respectively provided with a plurality of sockets and expansion slots, which is convenient for accessing optical fiber lines from different directions, and the sockets and expansion slots are arranged in three layers along the vertical direction, which is convenient for sliding up and down to change the number of sockets and expansion slots. In addition, the first slider 210 and the second slider 220 are also arranged at the lower part of the expansion component 200 and on both sides of the plug-in body 230. At the same time, the first slider 210 and the second slider 220 are slidably embedded in the first slide 101 and the second slide 102 respectively for connecting the transmission component 300.

[0046] It should also be noted that the shape of the plug-in body 230 in this embodiment can also be other polygonal prism shapes, such as an octagonal prism, etc.; the shape of the opening 103 can also be other polygonal shapes or a circle. At the same time, the shapes of the two are not limited by the conditions of mutual adaptation. For example, the plug-in body 230 in the shape of a hexagonal prism can also be matched with the rectangular opening 103. The side walls of the two do not need to be completely fitted, as long as the opening 103 can accommodate the plug-in body 230. In addition, when the number of sides of the plug-in body 230 changes, the number of corresponding socket panels 232 and expansion panels 234 also increases or decreases accordingly.

[0047] Then, if Figure 4 As shown in , the transmission assembly 300 is arranged in the housing 100, and is mainly used for the user to manually control the up and down movement of the expansion assembly 200 to change the number of the socket and the expansion slot. The transmission assembly 300 mainly includes a first screw rod 310, a second screw rod 320, and a transmission rod 330. Among them, the first screw rod 310 and the second screw rod 320 are respectively vertically embedded in the bottom of the first slider 210 and the second slider 220, and are threadedly connected by internal and external threads; the bottoms of the first screw rod 310 and the second screw rod 320 are both rotatably connected in the housing 100 through bearings; the first screw rod 310 and the second screw rod 320 are respectively sleeved with a first bevel gear 312 and a second bevel gear 332 near the bottom. At the same time, the transmission rod 330 is rotatably set in the shell 100 through the bearings at both ends thereof, and is sleeved with a third bevel gear 333 and a fourth bevel gear 334, and the third bevel gear 333 and the fourth bevel gear 334 are respectively meshed with the first bevel gear 312 and the second bevel gear 322. At the same time, one end of the transmission rod 330 extends to the outside of the shell 100 and is connected to a handwheel 336. The user can drive the transmission assembly 300 by turning the handwheel 336, and then control the expansion assembly 200 to move up and down to change the number of sockets and expansion slots.

[0048] A specific implementation of this embodiment is:

[0049] When connecting optical fiber cables and boards, first determine the number of sockets and expansion slots required; then, turn the hand wheel 336 to adjust the height of the expansion component 200, and extend one, two or three layers of sockets and expansion slots from above the opening 103 according to the determined number of sockets and expansion slots; then, follow the direction of the optical fiber cables and connect them to the sockets in the appropriate directions, and then connect the boards to the expansion slots in the remaining directions. The entire connection process is more convenient and flexible, and the space is fully utilized to increase the number of connections.

[0050] In this embodiment, the SDH optical transmission equipment provides a flexible insertion direction for the connected optical fiber lines by setting up a housing 100, an expansion component 200 and a transmission component 300 that cooperate with each other, relying on the different side directions of the expansion component 200 and the movable three-layer setting of the socket and the expansion slot, so as to facilitate its free setting, and increase the number of sockets and expansion slots, thereby realizing an increase in the wiring space of the SDH optical transmission equipment, and solving the problem in the prior art that the working efficiency of the existing SDH optical transmission equipment is limited due to the limitation of the number of interfaces and expansion slots.

[0051] Preferably, if Figure 2As shown, in this embodiment, the two socket panels 232 can also be arranged opposite to the first slider 210 and the second slider 220 on both sides of the plug-in body 230, and the optical fiber line sockets on the socket panel 232 can be dispersed to avoid being blocked by the first slider 210 and the second slider 220. This design also makes the expansion panel 234 not opposite to the first slider 210 and the second slider 220, which is convenient for connecting a larger HUB board, etc.

[0052] Preferably, in this embodiment, a cover panel 240 may be provided in the expansion assembly 200, connected to the top of the plug-in body 230. Indicator lights 242 corresponding to the various sockets and expansion slots are provided on the upper surface of the cover panel 240, and the cover panel 240 utilizes the upper space to provide the indicator lights 242, so that the user can observe the signal status of each optical fiber line.

[0053] However, in the above embodiment, due to the increase in the number of connected sockets and expansion slots, the working power of the SDH optical transmission equipment is required to increase accordingly. When fewer sockets and expansion slots are connected, the high power mode of the SDH optical transmission equipment causes energy waste. In order to further solve these problems on the basis of the first embodiment, a second embodiment is provided below.

[0054] See also Figure 4 The second embodiment provides an SDH optical transmission device whose power can be changed according to the number of accessible sockets and expansion slots. The SDH optical transmission device in the second embodiment further adds a control component 400 and improves the structure of the transmission component 300.

[0055] like Figure 4 As shown in , the transmission assembly 300 of the second embodiment is further provided with an external thread in the middle of the transmission rod 330, and a slide groove 104 is provided on the inner bottom wall of the housing 100. The transmission assembly 300 is further provided with a third slider 340, which is sleeved in the middle of the transmission rod 330 and threadedly connected with the transmission rod 330 through an internal thread, and the third slider 340 is also slidably embedded in the slide groove 104, and an integrally formed protrusion 342 is provided above the third slider 340. When the user turns the hand wheel 336 to drive the transmission assembly 300, the third slider 340 will also move along the direction of the slide groove 104, and the horizontal movement of the third slider 340 is synchronized with the vertical movement of the upper extension assembly 200.

[0056] like Figure 1 , Figure 4As shown in the figure, the control component 400 includes a power switch 440 arranged on the outer side wall of the housing 100, an internal circuit element, and a first mode switch button 410, a second mode switch button 420, and a third mode switch button 430 above the protrusion 342. Among them, the internal circuit element and the first mode switch button 410, the second mode switch button 420, and the third mode switch button 430 are all electrically connected, and the three are arranged above the third slider 340 along the direction of the slide slot 104. When the protrusion 342 abuts against the first mode switch button 410, the internal circuit element starts the low power mode, which cooperates with the connection between the single-layer socket on the expansion component 200 and the number of expansion slots; when the protrusion 342 abuts against the second mode switch button 420, the internal circuit element starts the medium power mode, which cooperates with the connection between the double-layer socket on the expansion component 200 and the number of expansion slots; when the protrusion 342 abuts against the third mode switch button 430, the internal circuit element starts the high power mode, which cooperates with the connection between the three-layer socket on the expansion component 200 and the number of expansion slots. At the same time, the internal circuit elements and the power switch 440 are also electrically connected. When it is necessary to stop working, the entire control component 400 can be turned off by turning off the power switch 440.

[0057] In addition, the first mode switch button 410 , the second mode switch button 420 and the third mode switch button 430 in this embodiment are preferably configured as arc-shaped surfaces protruding downward to reduce the resistance encountered by the protrusion 342 during the sliding process.

[0058] In the second embodiment, the SDH optical transmission equipment changes the power of the optical transmission device by setting the third slider 340 in the transmission component 300 and cooperating with the control component 400, so that the power of the optical transmission device changes with the increase or decrease of its access load, thereby solving the problem of energy waste in the above embodiment and making the SDH optical transmission equipment in the second embodiment have the advantages of energy saving and environmental protection.

[0059] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
