[0047] The present application provides a circuit board assembly 100, such as Figure 1 、 2 As shown, including:

[0048] The optical module housing 1 may be formed into a structure with an opening 10 on one side, and a fixing foot 11 is provided on the lower side of the optical module housing 1;

[0049] A circuit board 2, wherein a plurality of optical module areas 20 are formed on one side of the circuit board 2, wherein the optical module areas 20 are used to fix the optical module housing 1, and the fixing legs 11 on the optical module housing 1 are fixed to the optical module areas 20;

[0050] An indicator light board 3 includes a substrate 30 having a first solder pad 31 at a corner thereof and an indicator light 32 on the same side as the first solder pad 31 , wherein the indicator light 32 emits light toward a side away from the substrate 30 ; and

[0051] The light guide 4 is provided between the optical module housing 1 and the circuit board 2 and corresponds to the indicator light 32. That is, with respect to the first surface 2A and the second surface 2B included in the circuit board 2, if the optical module housing 1 is provided on the first surface 2A, the indicator light board 3 is provided on the second surface 2B, and the light guide 4 is provided on a side close to the first surface 2A, and is located between the circuit board 2 and the optical module housing 1. If the optical module housing 1 is provided on the second surface 2B, the indicator light board 3 is provided on the first surface 2A, and the light guide 4 is provided on a side close to the second surface 2B, and is located between the circuit board 2 and the optical module housing 1.

[0052] In which, a through hole 21 and a light column groove 22 extending from the through hole 21 to the edge of one side of the circuit board 2 are provided on the circuit board 2, and the light column groove 22 and the indicator light board 3 are located on different surfaces of the circuit board 2; the indicator light board 3 is welded to the second soldering pad 23 provided on the peripheral side of the through hole 21, and the indicator light 32 is accommodated in the through hole 21; the light guide column 4 is accommodated in the light column groove 22 and extends to the edge of the circuit board 2, and the light incident surface 40 of the light guide column 4 corresponds to the indicator light 32 in the through hole 21.

[0053] Since the indicator light 32 corresponds to the light incident surface 40 of the light guide column 4 in the through hole 21, the outgoing light of the indicator light 32 can be blocked by the side wall of the through hole 21 to avoid light leakage and maintain the stability of the light emitted by the indicator light 32.

[0054] On the circuit board 2, the opening 10 of the optical module housing 1 is generally oriented toward the front side of the network device, and the light-emitting surface 41 at the front end of the light guide column 4 also needs to extend to the front side of the network device. In order to increase the number of optical modules on the circuit board 2, in addition to setting the optical module housing 1 on one side of the circuit board 2, there is also a solution of setting the optical module housing 1 on both sides of the circuit board 2. Moreover, the optical module housing 1 on one side can also be set to have a multi-layer structure, and each layer can accommodate a group of optical modules. Generally speaking, in a network device, due to the size limitation of the network device, the optical module housing 1 on one side can accommodate two layers of optical modules, and it can be set according to actual needs without any restrictions.

[0055] First solder pads 31 are provided at the four corners of the indicator board 3. These first solder pads 31 can extend from one side surface of the indicator board 3 along the side edge and reach the other side surface of the indicator board 3, thereby improving the soldering reliability between the indicator board 3 and the circuit board 2. In addition, a receiving groove can be provided on the circuit board 2 to position and accommodate the indicator board 3, thereby further improving the efficiency and reliability of the soldering between the indicator board 3 and the circuit board 2.

[0056] As for the light guide column 4, one light guide column 4 can be set for each indicator light 32, or one light guide column 4 can be designed to correspond to multiple indicator lights 32. It can be set according to actual needs without any limitation.

[0057] exist Figure 2 In the figure, the thick dashed line represents the optical module area 20 , and the thin dashed line represents the through hole 21 and the optical column slot 22 opened on the circuit board 2 .

[0058] Through the setting of the above structure, the space between the optical module housing 1 and the circuit board 2 can be better utilized, and the indicator light 32 and the light guide column 4 for indicating the working status of the optical module can be deployed, which makes more reasonable use of the space on the front side of the network device and improves the utilization rate of the space on the front side of the network device.

[0059] Optional, such as Figure 1 As shown, a clamping arm 12 is formed on the surface of the optical module housing 1 facing the circuit board 2 , and the light guide 4 is clamped in the clamping arm 12 .

[0060] The optical module housing 1 is provided with a clamping arm 12 to clamp the light guide column 4, thereby preventing the light guide column 4 from shaking in the light column slot 22. The structure of the clamping arm 12 can be set as a clamping bar with two sides parallel to the light guide column 4, which clamps the light guide column 4, such as Figure 2 As shown, it can also be set to have an extension arm toward the circuit board 2 and a clamping arm parallel to the circuit board 2, which can be set according to actual needs. Among them, the clamping arm 12 is in the form of a clamping bar, which can reduce its occupation of the space between the circuit board 2 and the optical module housing 1, and further improve the utilization rate of the front space of the network equipment.

[0061] Optional, such as Figure 2 As shown, peripheral components 5 corresponding to the indicator light board 3 are also disposed on the circuit board 2 , and the peripheral components 5 are arranged outside the optical module area 20 .

[0062] The peripheral device 5 can be composed of electrical components such as resistors and capacitors to control the indicator light 32. In addition, setting the peripheral device 5 outside the optical module area 20 can avoid its influence on the lines and light guide column 4 within the optical module area 20, further improving the utilization rate of the space on the circuit board in the network equipment.

[0063] In addition, in order to simplify the preparation process of the circuit board 2, it is optional, such as Figure 3As shown, the optical column slot 22 is integrally formed with the through hole 21. This integral forming may be formed in a single process during the preparation of the circuit board 2. That is, in the process of milling the through hole 21, the portion from the through hole 21 to the edge of the circuit board 2 is removed. In this process, the second soldering pads 23 formed on the circuit board 2 need to be avoided so that the distance between the two second soldering pads 23 along the direction from which the optical column slot 22 extends to the edge of the circuit board 2 is greater than the width of the optical column slot 22.

[0064] The indicator light board 3 includes a first side 33 and a second side 34, wherein the length of the first side 33 is greater than that of the second side 34;

[0065] The light column slot 22 extends perpendicularly to the first side 33 .

[0066] Since the first side 33 is larger, the first soldering pads 31 provided at the corners of the first side 33 can have a larger size and be larger than the size of the light guide 4 . Therefore, the welding of the indicator board 3 is not affected by the light guide groove 22 .

[0067] In one possible implementation, Figure 4 As shown, the optical module area 20 is respectively provided on the first surface 2A of the circuit board 2 and the second surface 2B of the circuit board 2;

[0068] The optical module housing 1 is respectively disposed in the optical module area 20 of the first surface 2A and the optical module area 20 of the second surface 2B.

[0069] That is to say, an optical module housing 1A can be provided in the optical module area 20A of the first surface 2A, and an optical module housing 1B can be provided in the optical module area 20B of the second surface 2B. By respectively providing optical module housings 1 on the upper and lower surfaces of the circuit board 2, the optical module density on the front side of the network device can be improved.

[0070] Furthermore, the indicator light board 3A corresponding to the light module area 20A of the first surface 2A is welded to the second surface 2B, and the indicator light board 3B corresponding to the light module area 20B of the second surface 2B is welded to the first surface 2A.

[0071] like Figure 4 As shown, the optical module housing 1A is arranged in the optical module area 20A, and the optical module housing 1B is arranged in the optical module area 20B. When the optical modules are densely packed, it is easier to confirm the working status through the nearest light guide column 4 when checking the working status. Moreover, compared with the integral molding of the through hole 21 and the light column groove 22, the retention of the structure on the circuit board 2 can limit the scattering of the outgoing light, so that the outgoing light is less lost and enters the light incident surface 40 of the light guide column 4.

[0072] In order to achieve the above-mentioned effects, the indicator light board 3A corresponding to the optical module housing 1A arranged on the first surface 2A can be arranged between the optical module housing 1B and the second surface 2B, and the indicator light board 3B corresponding to the optical module housing 1B arranged on the second surface 2B can be arranged between the optical module housing 1A and the first surface 1A, the indicator light 32A is in the through hole 21A, and the indicator light 32B is in the through hole 21B.

[0073] Correspondingly, light guide 4A is housed in light slot 22A defined on first surface 2A, with its light entrance surface 40A housed within through-hole 21A and positioned opposite indicator light 32A. Light guide 4B is housed in light slot 22B defined on second surface 2B, with its light entrance surface 40B housed within through-hole 21B and positioned opposite indicator light 32B. This allows light exit surface 41A of light guide 4A to be closer to optical module housing 1A, and light exit surface 41B of light guide 4B to be closer to optical module housing 1B. This allows the operating status of the light guide 4 corresponding to the optical module to be observed from a closer distance from the front of the network device, improving the accuracy of viewing the optical module in the network device.

[0074] In one possible implementation, Figure 5 、 6 As shown, the optical module housing 1 is a housing that accommodates at least two layers of optical modules;

[0075] On the circuit board 2 , there are at least two through holes 21 corresponding to one optical module housing 1 , and at least two indicator light boards 3 soldered to the through holes 21 corresponding to one optical module housing 1 are arranged on the same surface of the circuit board 2 .

[0076] Since the optical module housing 1 can accommodate at least two layers of optical modules, each layer of optical modules needs to display its operating status through indicator lights. Based on the above-mentioned arrangement principles of the indicator light board 3 and light guide 4, the indicator light board 3 corresponding to the optical module housing 1 arranged on one side of the circuit board 2 is arranged on the other side of the circuit board 2. In other words, the indicator lights of at least two layers of optical modules need to be arranged on the same side surface, and on the opposite side of the optical module housing 1.

[0077] In this case, for each optical module housing 1 , a plurality of through holes 21 and optical column slots 22 may be transversely arranged on the circuit board 2 , where the transverse arrangement refers to a direction parallel to the edge of the circuit board 2 to which the optical column slots 22 extend.

[0078] In order to improve the accuracy of the staff's viewing of the working status of the optical module, a certain gap can be set between the two indicator lights 32 corresponding to the optical module housing 1 set on the same surface, such as Figure 5 、 6As shown, the indicator lights 32 on different surfaces can be interspersed. In the case of including indicator light panels 3A, 3B, 3C, and 3D, the indicator light panels 3A and 3C are arranged on the second surface 2B, corresponding to the light module housing 1A arranged on the first surface 2A, and the indicator light panels 3B and 3D are arranged on the third surface 2A, corresponding to the light module housing 1B arranged on the second surface 2B.

[0079] In this case, there can be multiple light guide columns 4, each light guide column 4 corresponds to an indicator light board 3, or a light guide column 4 can include multiple light input surfaces 40, light output surfaces 41 and conductive parts therebetween. It can be set according to actual needs without any restrictions.

[0080] Optionally, the light guide column 4, such as Figure 5 、 6 As shown, including:

[0081] At least two light guides 42, each light guide 42 corresponding to an indicator light board 3;

[0082] a light incident surface 40 , disposed at one end of the light guide 42 and facing the indicator light 32 ;

[0083] a light emitting surface 41 disposed at the other end of the light guide 42; and

[0084] The connecting column 43 is connected to the adjacent light guide 42. The height of the connecting column 43 is smaller than that of the light guide 42 to avoid occupying additional space on the circuit board 2.

[0085] Wherein, the light column slot 22, as Figure 7 As shown, including:

[0086] The light guide groove 220 corresponds to a light guide 42, wherein Figure 7 ; and

[0087] The connecting post groove 221 corresponds to a connecting post 43 .

[0088] During the assembly of the circuit board 2 , the light column slot 22 can be divided into a light guide slot 220 and a connecting column slot 221 , thereby accommodating the light guide columns 4 corresponding to the plurality of indicator light boards 3 .

[0089] Optionally, the number of the connecting columns 43 provided between the adjacent light guides 42 is at least two.

[0090] By connecting adjacent light guides 42 via a plurality of connecting pillars 43 , the reliability of the light guide pillars 4 can be improved and damage can be avoided.

[0091] Correspondingly, the present application also provides a network device, including:

[0092] The circuit board assembly 100 according to any one of the above items; and

[0093] An optical module is inserted into the optical module housing 1 of the circuit board assembly 100 .

[0094] The technical solutions provided by the embodiments of this specification may have the following beneficial effects:

[0095] In the embodiment of the present specification, in the circuit board assembly, a through hole is provided in the optical module area of ​​the circuit board to accommodate the indicator light board, and a light column groove connected to the through hole is formed to set the light guide column. The light incident surface of the light guide column and the indicator light on the indicator light board are arranged relative to each other in the through hole, so that the light output of the indicator light occupies a smaller space, thereby improving the space utilization on the front side of the network device.
