Description

Technical Field

[0001] The present application relates to the field of optical transmission technology, and more specifically, to an indicator light device and a network communication device. Background Art

[0002] In optical transport network (OTN) equipment, the board status can be quickly identified through the board indicator light. Currently, there are two main types of board light guide solutions. One is to transmit the light emitted by the light emitting diode (LED) to the board surface through a light guide structure (such as a light guide column), such as Figure 1 The other type is a solution where the side-emitting LED lamp directly emits light to the observation panel, such as Figure 1 As shown in (b). However, in the light-guiding column light-emitting solution, since the LED lamp is arranged on a single-board printed circuit board (PCB), the light-guiding column will occupy part of the PCB layout. At the same time, since there is a certain distance between the PCB and the observation panel, the solution has high requirements for the assembly of the light-guiding column. Generally, assembly limit structures are arranged at both ends of the light-guiding column, which causes the indicator light device to occupy too much space inside the single board. In addition, when the single board is a high-density light-emitting port single board, this solution is no longer applicable because it cannot compress the space volume occupied by the indicator light device. In the side-emitting solution, because the distance between the LED lamp and the observation panel is limited, the solution is prone to cross-lighting. At the same time, due to the influence of the PCB and the light port position, the indicator light positions of various single boards are often not uniform. Therefore, how to realize a small-volume indicator light device and improve the indication effect of the indicator light device is an urgent problem to be solved. Summary of the invention

[0003] The present application provides an indicator light device and a network communication device. The indicator light device provided by the present application is small in size and has a good indicating effect, which can not only save the internal space of the network communication device, but also realize the layout of the panels of multiple boards of the device in a unified position.

[0004] In a first aspect, an embodiment of the present application provides an indicator light device. The device comprises: a plastic structural member and a light board, wherein the plastic structural member is fixedly connected to the light board, wherein the plastic structural member is a structural member formed integrally with a plurality of light-guiding structures and a plastic body, wherein the plurality of light-guiding structures are used to transmit light emitted by a plurality of light-emitting diodes LED on the light board to the first surface of the plastic body for emission; the light board comprises a printed circuit board PCB, the plurality of LEDs arranged on the first surface of the PCB, and a light board holder arranged on the second surface of the PCB, wherein the light board holder is electrically connected to the single board via a cable.

[0005] The indicator light device provided by the present application no longer arranges the LED on a single-board PCB, but uses an independent light board and a plastic structural member matched with the light board to make the volume of the indicator light device flexible according to the design requirements. At the same time, the indicator light device avoids the use of an assembly limit structure, so the volume of the indicator light device can be reduced. In addition, since the present application can provide an indicator light device with a smaller volume, when applied to single boards of various models, the indicator light device provided by the present application can be installed at a uniform position on the single board, occupying the same small space on each single board, thereby achieving the uniformity of the indicator light position.

[0006] In combination with the first aspect, in some implementations of the first aspect, the plurality of light guide structures are a plurality of through holes. Providing through holes on a plastic structural member does not require high processing accuracy of the plastic structural member and is easy to process, making the solution easy to implement.

[0007] In combination with the first aspect, in some implementations of the first aspect, the plurality of light-guiding structures are a plurality of hollow structures protruding from the first surface and the second surface of the plastic body. The hollow structures can gather the light during transmission, making it difficult for the light to diffuse, thereby achieving the purpose of improving the indication effect.

[0008] In combination with the first aspect, in some implementations of the first aspect, the plurality of light guide structures are a plurality of light guide columns protruding from the first surface and the second surface of the plastic body. The light guide columns are used to conduct light, which can improve the efficiency of conducting light, avoid the loss of light energy, and thus improve the indication effect.

[0009] In combination with the first aspect, in certain implementations of the first aspect, the second surface of the plastic body is further formed with a convex light isolation structure, the light isolation structure is located between the multiple light guide structures, and the light isolation structure is used to isolate the light emitted from the multiple light guide columns. Based on this solution, by simultaneously forming the light isolation structure on the plastic structural member, the light crosstalk phenomenon that occurs when the distance between the light guide columns is too small can be avoided.

[0010] In combination with the first aspect, in some implementations of the first aspect, the plastic structural member is further formed with a plurality of elastic buckles protruding toward the second surface of the plastic structural member, wherein the plastic structural member is fixedly connected to the light board, including: the plastic structural member is fixedly connected to the light board via the plurality of elastic buckles. Based on this solution, the light board can be assembled more easily, the stability is improved, and the disassembly is convenient.

[0011] In combination with the first aspect, in some implementations of the first aspect, the number of the plurality of elastic buckles is 3, and the plurality of elastic buckles are respectively formed on three sides of the plastic body. By respectively setting the three elastic buckles on the three sides of the plastic body, the stability of the fixation between the plastic structure and the light board can be further improved.

[0012] In combination with the first aspect, in some implementations of the first aspect, the volume of the indicator light device is less than or equal to 3.2 cm 3 This can greatly reduce the volume of the indicator light device in the equipment, thereby saving equipment space.

[0013] In conjunction with the first aspect, in certain implementations of the first aspect, the height of the indicator light device is less than or equal to 17.6 mm. The indicator light device provided by the present application has a relatively small height, which can effectively reduce the volume of the indicator light device.

[0014] In conjunction with the first aspect, in certain implementations of the first aspect, the plastic structural part is formed by two-color injection molding. This solution can ensure the reliability and process maturity of the generated plastic structural part.

[0015] In a second aspect, an embodiment of the present application provides a network communication device, which includes a single board and the indicator light device as described in the first aspect or any possible implementation thereof, wherein the indicator light device is fixed on the single board.

[0016] In conjunction with the second aspect, in some implementations of the second aspect, the indicator light device is fixed to the single board, including: the first surface of the plastic structure of the indicator light device is fixed to the inner surface of the panel of the single board by gluing. The indicator light device is fixed to the single board by gluing, which is easy to operate, simple and convenient.

[0017] In combination with the second aspect, in some implementations of the second aspect, the single board includes a fixing structure that is protruding on both the inner surface of the panel of the single board and the outer surface of the panel of the single board, wherein the portion protruding from the outer surface of the panel is used as a hand-held portion when the single board is inserted into a device, and the indicator light device is fixed to the single board, including: the indicator light device is fixed to the single board by pressing the portion protruding from the inner surface of the panel. By using the existing components of the single board to further press and fix the indicator light device to the single board, the fixing strength of the indicator light device is further improved.

[0018] In a third aspect, an embodiment of the present application provides a communication system, which includes: at least one device as described in the second aspect or any possible implementation manner thereof. BRIEF DESCRIPTION OF THE DRAWINGS

The singular expressions "a", "an", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless the context clearly indicates otherwise.

[0039] Fourth, references to "one embodiment" or "some embodiments" etc. described in this specification mean that one or more embodiments of the present application include a particular feature, structure or characteristic described in conjunction with the embodiment. Therefore, the phrases "in some embodiments", "in other embodiments", etc. appearing in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0040] Fifth, the same reference numerals are used in the embodiments of the present application to represent the same components or parts. In addition, the various parts in the drawings are not drawn to scale, and the sizes and dimensions of the parts shown in the drawings are only examples and should not be construed as limiting the present application.

[0041] Sixth, the indicator light device provided by the present application can be applied to any network communication equipment including a single board, such as OTN equipment, optical access equipment, data communication equipment (such as switches, routers, etc.), etc. In the embodiments of the present application below, the indicator light device is applied to OTN equipment as an example for explanation, but the protection scope of the present application is not limited to OTN equipment.

[0042] Seventh, the present application relates to a light guide column. A light guide column is an optical element that transmits light from a light source to another point at a certain distance from the light source with minimal loss, wherein the light is transmitted inside the light guide column by total internal reflection.

[0043] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0044] The indicator light device and the single board provided in the embodiments of the present application can be applied to OTN equipment. Figure 2 The hardware structure diagram of a possible OTN device 200 applicable to the indicator light device embodiment provided in the present application is shown in FIG. Specifically, the OTN device 200 includes a branch board 201, a cross board 202, a circuit board 203, an optical layer processing board ( Figure 2 (not shown) and system control and communication board 204. Among them, the indicator light device provided by the present application can be applied to Figure 2 One or more of the tributary board 201, cross board 202, line board 203, or system control and communication board 204 shown. As required, the type and quantity of boards included in the OTN device may be different. For example, an OTN device as a core node does not have a tributary board 201. For another example, an OTN device as an edge node has multiple tributary boards 201, or does not have an optical cross board 202. For another example, an OTN device that only supports electrical layer functions may not have an optical layer processing board.

[0045] The tributary board 201, the cross board 202 and the line board 203 are used to process the electrical layer signals of the OTN. Among them, the tributary board 201 is used to realize the reception and transmission of various customer services, such as synchronous digital hierarchy (SDH) services, packet services, Ethernet services and fronthaul services. Further, the tributary board 201 can be divided into a customer-side optical transceiver module and a signal processor. Among them, the customer-side optical transceiver module can also be called an optical transceiver, which is used to receive and / or send service data. The signal processor is used to realize the mapping and demapping processing of service data to data frames. The cross board 202 is used to realize the exchange of data frames and complete the exchange of one or more types of data frames. The line board 203 mainly realizes the processing of line-side data frames. Specifically, the line board 203 can be divided into a line-side optical module and a signal processor. Among them, the line-side optical module can be called an optical transceiver, which is used to receive and / or send data frames. The signal processor is used to realize the multiplexing and demultiplexing, or mapping and demapping processing of the data frames on the line side. The system control and communication board 204 is used to implement system control. Specifically, information can be collected from different boards, or control instructions can be sent to the corresponding board. It should be noted that, unless otherwise specified, the specific components (such as signal processors) can be one or more, and this application does not limit it. It should also be noted that this application does not impose any restrictions on the type of boards included in the device and the functional design and quantity of the boards. It should be noted that in a specific implementation, the above two boards may also be designed as one board. In addition, the network device may also include a power supply for backup, a fan for heat dissipation, etc.

[0046] Figure 3 This is a schematic structural diagram of the first plastic structural member 300 provided in the embodiment of the present application. The plastic structural member 300 can be fixedly connected with the corresponding light board to form the indicator light device provided in the embodiment of the present application. Figure 3 As shown, the plastic structure 300 includes a plastic body 310 (including a first surface 311 and a second surface 312) and a plurality of light guide structures 320 (such as Figure 3 The light guide structures 321, 322, 323 and 324 are shown. The plurality of light guide structures 320 are used to transmit the light emitted by the plurality of LEDs on the light board to the first surface 311 of the plastic body 310 for emission.

[0047] Optionally, the plurality of light guide structures may be in various ways including but not limited to the following, for example, the plurality of light guide structures 320 are a plurality of through holes. Alternatively, the plurality of light guide structures 320 are a plurality of hollow structures, which protrude from the first surface 311 and the second surface 312 of the plastic body, as shown in the top view. Figure 4Alternatively, the plurality of light guide structures 320 are a plurality of light guide columns protruding from the first surface 311 and the second surface 312 of the plastic body, such as Figure 4 As shown. Specifically, the plastic structural part 300 can be a structural part integrally formed by an injection mold process. Among them, the method of generating a plastic structural part 300 with multiple through holes includes but is not limited to the following methods: for example, the plastic structural part 300 can be generated by one-time molding in an injection mold containing multiple through holes. Alternatively, after the plastic structural part is generated in an injection mold that does not contain multiple through holes, the plastic structural part 300 with multiple through holes is generated by a punching process. At this time, the material of the plastic structural part 300 can be polycarbonate (polycarbonate, PC). Similarly, the method of generating a plastic structural part 300 with multiple hollow structures includes but is not limited to the following methods: for example, the plastic structural part 300 can be generated by one-time molding in an injection mold containing multiple hollow structures. Alternatively, after a solid plastic structural part is first generated at multiple hollow structures, a plastic structural part 300 with multiple hollow structures is generated by a punching process. At this time, the material of the plastic structural part 300 can also be PC. The plastic structural member 300 including a plurality of light guide columns can be integrally formed by adopting a two-color injection molding process, wherein the plastic body 310 and the plurality of light guide columns are made of different materials, for example, the material of the plastic body 310 is PC, and the material of the light guide column 320 is transparent polycarbonate (clear-polycarbonate, PC_clear) or polymethylmethacrylate (polymethylmethacrylate, PMMA).

[0048] It is understandable that in Figure 3 In the figure, the plurality of light guide structures 320 are shown in the form of a plurality of through holes or a plurality of light guide columns, that is, Figure 3 The embodiment in which the light-guiding structure is a plurality of through holes is not shown.

[0049] In order to prevent the distance between the multiple light guides 320 from being too small, causing the indicator lights to produce cross-light when in use, Figure 5 A schematic structural diagram of a second plastic structural member 500 of an embodiment of the present application is provided. The plastic structural member 500 can be fixedly connected with a corresponding light board to form an indicator light device provided in an embodiment of the present application. The plastic structural member 500 includes a plastic body 310 (including a first surface 311 and a second surface 312), a plurality of light guide structures 320 (such as Figure 3The light guide structure 321, light guide structure 322, light guide structure 323 and light guide structure 324) and the light isolation structure 510 are shown. The light isolation structure 510 is located between the plurality of light guide pillars 320 and is protruded from the second surface 312 of the plastic body 310. Specifically, the light isolation structure 510 is used to isolate the light emitted from the plurality of light guide structures 320. The description of other structures in the plastic structure 500 can be referred to in detail. Figure 3 It is understandable that when the plastic structural member 500 including the light-isolating structure 510 is produced by the injection molding process, the plastic mold should also include a mold portion of the light-isolating structure 510 , and the light-isolating structure 510 and the plastic main body 310 of the plastic structural member 500 are made of the same material.

[0050] It should be noted that Figure 5 The light-isolating structure 510 is described by taking the protruding "cross shape" as an example. The light-isolating structure can also be in other shapes, such as a wave shape, etc., and this application does not limit this.

[0051] In order to make the fixed connection between the plastic structure and the light board in the indicator light device provided in the present application more stable, a plurality of elastic clips can be formed on the plastic structure used in conjunction with the light board to achieve a fixed connection between the plastic structure and the light board. Figure 6 A schematic structural diagram of a third plastic structural member 600 of an embodiment of the present application is provided. The plastic structural member 600 includes a plastic body 310 (including a first surface 311 and a second surface 312), a plurality of light guide structures 320 (such as Figure 3 The light guide structure 321, light guide structure 322, light guide structure 323 and light guide structure 324 shown in the figure), the light isolation structure 510 and three elastic buckles 610 (including elastic buckle 611, elastic buckle 612 and elastic buckle 613, wherein the elastic buckle 612 is Figure 6 It is not shown in Figure 7 Top view and Figure 8 Specifically, the elastic buckle 610 is used to connect the plastic structure 600 with the corresponding lamp panel (such as the following Fig. 9 The description of other structures in the plastic structural member 600 may refer to Figure 3 and Figure 5 It is understandable that when the plastic structural member 600 including the elastic buckle 610 is produced by the injection molding process, the plastic mold should also include a mold portion of the elastic buckle 610 , and the elastic buckle 610 and the plastic main body 310 of the plastic structural member 600 are made of the same material.

[0052] Figure 7 and Figure 8They are respectively a top view and a front view of the plastic structural member 600, such as Figure 7 and Figure 8 As shown, three elastic buckles protrude from the second surface of the plastic structure and are respectively located on three sides of the plastic body 310. It can be understood that Figures 6 to 8 The plastic structure includes three elastic buckles as an example for illustration. In other embodiments, the plastic structure may include other numbers of elastic buckles. For example, when the area of ​​the light board is large, the plastic structure may include more elastic buckles (such as 4, 5, etc.) to ensure a stable connection with the light board. When the area of ​​the light board is small, the plastic structure may include fewer elastic buckles (such as two) to ensure easy detachment from the light board.

[0053] Fig. 9 The front view of the first surface 911 of a light board 900 provided in the embodiment of the present application is as follows. It can be understood that the light board 900 and the plastic structure 300 or the plastic structure 500 or the plastic structure 600 can respectively form different indicator light devices, that is, the plastic structure 300 or the plastic structure 500 or the plastic structure 600 can be used as a structural member used in conjunction with the light board 900. The light board 900 includes a PCB 910, a plurality of LEDs 920 (such as LEDs 920, ... Fig. 9 The LEDs 921, 922, 923 and 924 shown in the figure and the light board holder 930 (as shown below) arranged on the second surface 912 of the PCB 910 Fig.10 Side view of light board 900 and Fig.11 (as shown in the front view of the second surface 912 of the light panel 900).

[0054] It should be noted that when the light board 900 is used in conjunction with the plastic structural member 300 or the plastic structural member 500, in some embodiments, the first surface 911 of the PCB 910 and the second surface 312 of the plastic body 310 are fixed by dispensing glue; or, in other embodiments, the first surface 911 of the PCB 910 and the second surface 312 of the plastic body 310 are fixed by screws, and in this case, the PCB 910 and the plastic body 310 are also provided with through holes for installing the fixing screws. When the light board 900 is used in conjunction with the plastic structural member 600, the first surface 911 of the PCB 910 and the second surface 312 of the plastic body 310 are fixed by dispensing glue; or, in other embodiments, the first surface 911 of the PCB 910 and the second surface 312 of the plastic body 310 are fixed by screws. Figure 6 The three elastic buckles 610 are fixed.

[0055] It is understandable that the fixing method of glue dispensing makes it difficult to disassemble the light board 900 and the plastic structural member 300 (or the plastic structural member 500). Therefore, it can be used in some occasions where the light board 900 and the plastic structural member 300 (or the plastic structural member 500) do not need to be disassembled. At the same time, although the use of screws to fix can make the PCB 910 and the plastic body 310 easy to disassemble and install, since the threaded through holes for the screws need to be reserved on the PCB 910 and the plastic body 310, this solution can be applied to the use scenario where the light board area is larger. For the method of fixing the PCB 910 and the plastic body 310 by means of the elastic buckle 610, this method can make the light board 900 easy to assemble and the PCB 910 and the plastic body 310 easy to disassemble.

[0056] In addition, the above embodiment only illustrates the case where the light board includes 4 LED lamps, and the corresponding plastic structural member 600 includes 4 light guide columns. The protection scope of the present application is not limited to this, that is, the number of LED lamps on the light board provided by the present application can be one or more, and the number of light guide structures (such as light guide columns) on the plastic structural member can be one or more. That is, the light board provided by the present application can also include other numbers of LED lamps, and the number of light guide columns on the plastic structural member is not limited to 4. It should also be noted that in the present application scheme, the number of LED lamps included in the light board can be different from the number of light guide columns on the plastic structural member used in conjunction with it. For example, the number of LED lamps included in the light board can be less than the number of light guide columns on the plastic structural member. At this time, the light guide columns that are not used with LEDs will no longer emit light. In addition, Fig. 9 The dimensions of the respective side lengths of the light panel 900 are also shown. Fig.10 The thickness of the light board 900 is shown. It is understandable that the design (including shape and size, etc.) of the light board and plastic structural member provided in the present application can be flexibly designed according to the use requirements. Fig. 9 and Fig.10 The dimensions of the side lengths of the light board 900 and the thickness of the light board 900 shown are merely examples provided in the present application.

[0057] Next, the indicator light provided in the embodiment of the present application and the method for installing the indicator light in a single board are described.

[0058] Fig.12 A schematic structural diagram of an indicator light device 1200 provided in an embodiment of the present application, wherein: Fig.12 The above Figure 6 The plastic structure 600 and Fig. 9The light board 900 shown is used as an example. Specifically, the indicator light device 1200 includes 4 LED lights, and the plastic structure 600 and the light board 900 are fixed together by 3 elastic buckles, and the buckling areas of the 3 elastic buckles are 2.08 mm and 1.2 mm, respectively. 2 , 1.75mm 2 and 3.12mm 2 .

[0059] Understandably, Fig.12 This is only one example of the indicator light device provided in this application. The indicator light device provided in this application can be customized according to the application requirements. Therefore, in other embodiments, the dimensions of each side of the light board can be Fig.12 The dimensions shown are different, the thickness of the light board can also be thinner or thicker according to the requirements of wiring, and the shape of the light board can also be different from that in the above embodiments.

[0060] Fig.13 Schematic diagram of the installation of the plastic structural member 600 on the single board 1300. Specifically, the first surface 311 of the plastic body 310 is fixed to the inner surface of the panel of the single board 1300 by pasting (such as glue, etc.), and is fixed to the single board 1300 by pressing the fixing structure 1310 in the single board 1300. The fixing structure 1310 protrudes toward the inner surface of the panel of the single board 1300 and the outer surface of the panel of the single board 1300, respectively, and the part protruding from the outer surface of the panel of the single board 1300 is used as the hand-held part when the operator inserts the single board 1300 into the board slot of the OTN device (as shown below). Fig.15 As shown in the schematic diagram of the panel of the single board in FIG. 1 , the portion protruding from the inner surface of the single board 1300 is the portion that compresses the plastic structural member 600 .

[0061] Fig.14 The figure is a schematic diagram of the installation of the indicator light device 1200 in the OTN device 1400. The light board seat 930 of the indicator light device 1200 is connected to the connection seat 1420 on the PCB 1410 of the OTN device 1400 through the cable 1430, so that the four indicator lights can achieve different states by receiving the instructions of the OTN device 1400, for example, Fig.15 The four indication states shown are hardware status (STAT), software status (PROG), service alarm indication (SRV) and service activation status (ACT). It can be understood that Fig.14 This is only a partial structural diagram of the OTN device. The OTN device 1400 also includes an optical module (as shown below Fig.15It is also shown that there are other structures such as the interface of the optical module, i.e., the optical port, on the panel of the single board 1300, which are not limited or elaborated in this application. In addition, generally speaking, according to visual habits, the human eye is easy to notice the indicator light in the upper left corner of the single board, so Fig.15 The indicator light device is located at the upper left corner of the single board 1300 as an example. In other embodiments, the indicator light device can also be located at other positions of the single board, and this application does not limit this.

[0062] It should be noted that when the indicator light device 1200 is installed in the OTN device, the length, width and height of the internal space of the OTN device occupied by it are 16.4 mm, 11.3 mm and 17.6 mm respectively. At the same time, after the indicator light device 1200 is installed, the volume of the indicator light device is 3.2 cm3.
