[0020] It should be understood that although the terms first, second, third, etc., may be used in this specification to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this specification, first information may also be referred to as second information, and similarly, second information may also be referred to as first information.

[0021] This application provides a single-board 100, such as Figure 1-3 As shown, it includes: The base plate 1 can be used to form a receiving space to accommodate various structures in the single plate 100. Light guide post 2, such as Figure 2 As shown, a plate groove 20 is formed on the light guide post 2, and the light guide post 2 is disposed on the base plate 1; Interface board 3, such as Figure 3 As shown, the first side 30 of the interface board 3 is held in the board groove 20, and an indicator light 31 is formed on the surface of the interface board 3. The indicator light 31 is located at the edge of the first side 30. The light guide post 2 has a light inlet 21 formed on the side wall of the slot 20. The light inlet 21 corresponds to the indicator light 31. The light outlet 22 of the light guide post 2 extends to the front side of the single board 100. The front side of the single board 100 refers to the side of the single board 100 used for plug-in interfaces. That is to say, the front side of the single board 100 is the terminal plug-in side of the single board 100. The terminal can refer to an optical module or cable connector, etc.

[0022] When assembling the single board 100, the light guide post 2 can be first placed on the base plate 1, for example, by using screws or snap-fits, with the slot 20 on the light guide post 2 facing away from the base plate 1. When installing the interface board 3, the first side 30 of the interface board 3 is inserted into the slot 20; this first side 30 can be considered the mounting edge of the interface board 3. To display the status of each interface, multiple indicator lights 31 on the interface board 3 can be inserted into the slot 20, opposite the light inlet 21 in the slot 20, to emit light to the light outlet 22, allowing the operator to observe the status of each interface from the front of the single board 100. The number of light inlet 21 in the slot 20 can be consistent with the number of interfaces on the interface board 3, and can be set according to requirements.

[0023] With the above structure, the interface board 3 can be vertically installed through the light guide column 2. On the one hand, it can increase the number of interfaces in the limited space on the single board 100. On the other hand, the heat dissipation area of ​​each interface can be increased by vertical setting, thereby improving the heat dissipation effect of the single board and even the communication equipment.

[0024] Optionally, the light guide post 2, such as Figure 2 As shown, it also includes: The column 23 has a groove 20 formed on the side surface 23A of the column 23 away from the base plate 1. A fixed end 23C is formed on the side surface 23B of the column 23 facing the base plate 1. The fixed end 23C does not overlap with the projection of the groove 20 on the horizontal plane.

[0025] To improve the reliability of the interface board 3, the light guide post 2 can be fixed to the base plate 1 by screws or other means, with the screws penetrating the light guide post 2 from top to bottom. Therefore, a fixing end 23C can be provided, extending from one end of the slot 20, for example, towards the rear of the single board 100, to the left and right sides. A fixing hole 23D is formed on this fixing end 23C, ensuring that the slot 20 and the fixing end 23C do not overlap when projected onto a horizontal plane. During installation, the screw passes through the fixing hole 23D and is screwed into the base plate 1, thereby fixing the light guide post 2 and providing a more reliable fixation for the interface board 3 inserted into the slot 20.

[0026] Optional, such as Figure 2 As shown, a positioning part 23E is formed on the side surface 23B of the column 23 facing the base plate 1, and the positioning part 23E and the projection of the plate groove 20 on the horizontal plane overlap.

[0027] Due to the fixed position requirement of the light guide post 2, it is possible to require pre-positioning during installation. When the space of the light guide post 2 is limited, the positioning part 23E (such as the positioning post) can be set close to the position of the board groove 20, that is, the projections of the positioning part 23E and the board groove 20 on the horizontal plane at least partially overlap or completely overlap, thereby improving the compactness of the component structure in the single board and further increasing the density of interfaces in the single board and even communication equipment.

[0028] Optional, such as Figure 2 As shown, the plate groove 20 includes: The clamping arm 20A protrudes from the side surface 23A of the column 23 away from the base plate 1, and the light inlet 21 is formed on the opposite side of the pair of clamping arms 20A.

[0029] The clamping arms 20A are arranged in pairs. A pair of clamping arms 20A or multiple pairs of adjacent clamping arms 20A formed on a light guide post 2 can clamp an interface board 3. When the interface density on the interface board 3 increases, the indicator lights 31 can be set on the two sides of the first side 30 (i.e., the two surfaces of the interface board 3). On the opposite side of the paired clamping arms 20A, i.e., at the position where the board groove 20 is formed, light inlet ports 21 can be formed on the clamping arms 20A on both sides respectively. When the interface board 3 is inserted into the board groove 20, the indicator lights 31 on the two surfaces of the interface board 3 can correspond to the light inlet ports 21 on the clamping arms 20A on both sides respectively, so as to realize the indication of the interface status when there are more interfaces.

[0030] Optional, such as Figure 4 As shown, a positioning protrusion 20B is formed between adjacent, paired clamping arms 20A; A positioning opening 32 is formed on the first side 30, and the positioning protrusion 20B cooperates with the positioning opening 32 to position the interface plate 3.

[0031] To more accurately align the indicator light 31 and the light inlet 21 and prevent misalignment between the interface board 3 and the light guide post 2, a positioning protrusion 20B can be formed in the slot 20. When there is only one pair of clamping arms 20A, the positioning protrusion 20B can be positioned anywhere on the light guide post 2 (e.g., in the slot 20, perpendicular to the extension direction of the slot 20). When there are multiple pairs of clamping arms 20A, the positioning protrusion 20B can be positioned between adjacent pairs of clamping arms 20A. Generally, to increase the interface density of the single board, multiple pairs of clamping arms 20A are provided. Therefore, positioning the positioning protrusion 20B between adjacent pairs of clamping arms 20A can further increase the number of light inlets 21 that the light guide post can accommodate. Thus, with an increased number of interfaces on the interface board 3, the number of indicator lights providing status indication can be increased within a limited space.

[0032] To improve the smoothness of the connection between the interface board 3 and the light guide post 2, optionally, such as Figure 4 As shown, the edges of the positioning port 32 and the positioning protrusion 20B are chamfered.

[0033] Optional, such as Figure 1 As shown, a first connector 33 is provided on the front side of the interface board 3 away from the single board 100, and the insertion interface 33A of the first connector 33 faces the base plate 1. The single board 100 also includes: The motherboard 4 has a second connector 40 at one end near the front of the single board 100, and the second connector 40 is inserted and engaged with the first connector 33.

[0034] When fixing the interface board 3 to the light guide post 2, the first connector 33 and the second connector 40, which are vertically connected, can be set to a mating form. This allows for the mating of the connectors and the fixing of the interface board 3 when it is inserted downwards, thereby further improving the installation efficiency of the single board.

[0035] Optional, such as Figure 1 As shown, interfaces 34 are provided on both sides of the interface board 3.

[0036] The interfaces on both sides further increase the interface deployment density on the single board.

[0037] Optional, such as Figure 1 As shown, a guide post 10 is provided on the base plate 1, and a guide seat 35 that cooperates with the guide post 10 is provided on the interface plate 3.

[0038] The guide structure on the base plate 1 and the interface plate 3 can further improve the efficiency of vertical insertion and fixing of the interface plate.

[0039] Correspondingly, this application provides a communication device 200, such as Figure 5 As shown, it includes: The single board 100 described in any of the above items.

[0040] The communication device 200 can be a router, switch, server, firewall, etc., and the single board 100 can be a network board, service board, switching module, etc., whichever is required.

[0041] The technical solutions provided in the embodiments of this specification may include the following beneficial effects: In the embodiments described in this specification, in the aforementioned single board, the light guide post is fixed to the base plate, and a slot is formed on the light guide post to engage the interface board. This allows the interface board to be vertically mounted in the single board via the light guide post, eliminating the need for additional structures to fix the interface board and increasing the interface density in the limited space of the communication device.
