Detailed implementation manners

[0028] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. Now, with reference to the accompanying drawings, the preferred embodiments of the present utility model will be described in detail.

[0029] An embodiment of the present utility model provides a fixed mounting box, as Figures 1 to 7As shown, it includes a housing 10 and an elastic member 20. The housing 10 includes an upper housing 110 and a lower housing 120 that are snap-fitted to each other. The upper housing 110 and the lower housing 120 enclose an installation cavity 101. The elastic member 20 is provided on the housing 10, and the free end of the elastic member 20 is located in the installation cavity 101. Along the length direction of the housing 10, an elastic installation space is formed between the free end of the elastic member 20 and one end of the housing 10.

[0030] In this embodiment, through the mutual snap-fitting of the upper housing 110 and the lower housing 120, an installation cavity 101 can be enclosed, which provides a stable installation environment for the MT ferrule 30. Specifically, when the MT ferrule 30 is installed in a fixed installation box, the MT ferrule 30 is located in the elastic installation space formed between the free end of the elastic member 20 and one end of the housing 10. Under the interaction of the elastic member 20 and the housing 10, the first connector 310 and the second connector 320 of the MT ferrule 30 are elastically squeezed, strengthening the connection strength between the first connector 310 and the second connector 320, thereby ensuring the coupling efficiency of the optical fiber 40 and improving the qualified rate of the finished product. At the same time, the structure of the fixed installation box in this embodiment is simple, and the overall integration degree after installing the MT ferrule 30 is high, and it can be applied to AOC optical module products with smaller internal dimensions.

[0031] As a preferred solution of this embodiment, as Figures 2 to 3 shown, the upper housing 110 includes a first mounting plate 111. On the side of the first mounting plate 111 close to the lower housing 120, clamping arms 112 are respectively arranged along the periphery. The lower housing 120 includes a second mounting plate 121. On the side of the second mounting plate 121 facing away from the first mounting plate 111, clamping platforms 122 are respectively formed along the periphery. The clamping arms 112 are respectively snap-connected to the clamping platforms 122.

[0032] The above structure gives an example of the snap-fitting connection between the upper housing 110 and the lower housing 120. Specifically, the upper housing 110 includes a first mounting plate 111, and the lower housing 120 includes a second mounting plate 121. By respectively arranging the clamping arms 112 around the first mounting plate 111 and snap-connecting them to the clamping platforms 122 formed around the second mounting plate 121 one by one, the connection between the upper housing 110 and the lower housing 120 is realized. The above snap-fitting operation is convenient. The operator only needs to bring the upper housing 110 and the lower housing 120 closer to each other to complete the snap connection between the clamping arms 112 and the clamping platforms 122, improving the usability.

[0033] In the specific implementation process, the number of the clamping arms 112 and the clamping platforms 122 is not specifically limited and can be adaptively adjusted according to the shape, size of the housing 10 and the actual use requirements. For example, the housing 10 in this embodiment has a rectangular structure. To ensure the connection stability between the upper housing 110 and the lower housing 120, Figure 1An example is given in which the number of clamping arms 112 and clamping platforms 122 is set to four, and they are correspondingly distributed at the four right angles of the rectangular structure to enhance the fixing strength of the housing 10. The connection stability of the MT ferrule 30 provided in the housing 10 is enhanced. Of course, the number of clamping arms 112 and clamping platforms 122 can also be set to 5, 6, 8, etc., and no specific limitation is made here.

[0034] As a preferred solution of this embodiment, as Figure 2 shown, the clamping arm 112 includes a connecting arm 1121 and a clamping portion 1122. The connecting arm 1121 is connected to the first mounting plate 111, and the clamping portion 1122 cooperates with the clamping platform 122 to form a clamping connection.

[0035] The above structure gives a structural example of the clamping arm 112. Specifically, the clamping arm 112 includes a connecting arm 1121 and a clamping portion 1122. The connecting arm 1121 is used to connect with the first mounting plate 111, and the clamping portion 1122 is used to cooperate with the clamping platform 122 to achieve clamping, completing the buckling of the upper housing 110 and the lower housing 120. The above clamping arm 112 has an L-shaped structure.

[0036] As a preferred solution of this embodiment, as Figure 3 shown, on one side of the second mounting plate 121 close to the first mounting plate 111, a first side plate 123 and a second side plate 124 are respectively arranged at both ends along the length direction. The first side plate 123 and the second side plate 124 abut against the first mounting plate 111; the first mounting plate 111, the second mounting plate 121, the first side plate 123 and the second side plate 124 enclose an installation cavity 101.

[0037] Here gives a structural example of the second mounting plate 121. The first side plate 123 and the second side plate 124 are arranged at both ends of the second mounting plate 121. After the upper housing 110 and the lower housing 120 are buckled, the first side plate 123 and the second side plate 124 abut against the first mounting plate 111, and at the same time, the first mounting plate 111, the second mounting plate 121, the first side plate 123 and the second side plate 124 enclose the installation cavity 101. The above structural setting can form the above installation cavity 101 along the length direction of the housing 10, and at the same time, there is a certain distance between the first side plate 123 and the second side plate 124, which can enable the optical fibers 40 on the first connection head 310 and the second connection head 320 of the MT ferrule 30 to extend in the reverse direction along the length direction of the housing 10, so that the optical fibers 40 are connected to external communication devices.

[0038] As a preferred solution of this embodiment, as Figure 4As shown, the elastic member 20 includes a connected mounting piece 210 and elastic arms 220. The mounting piece 210 is inserted between the first mounting plate 111, the first side plate 123 and the second side plate 124. The elastic arms 220 are located within the mounting cavity 101. One end of the first side plate 123 and the second side plate 124 away from the elastic member 20 forms a resisting arm 126, and an elastic mounting space is formed between the elastic arms 220 and the resisting arm 126.

[0039] Here, a structural example of the elastic member 20 is given. Specifically, the elastic member 20 includes a connected mounting piece 210 and elastic arms 220. The mounting piece 210 is used to be inserted between the first mounting plate 111, the first side plate 123 and the second side plate 124 to fix the elastic member 20 on the housing 10. And the above-mentioned elastic mounting space is formed between the elastic arms 220 and the resisting arm 126 to provide an elastic supporting force for the MT ferrule 30, and to extend the rectangle so that the MT ferrule 30 can be stably arranged within the housing 10.

[0040] As a preferred solution of this embodiment, as Figure 4 shown, there are two elastic arms 220, and the two elastic arms 220 are arranged at both ends of the mounting piece 210 at a preset distance.

[0041] Among them, elastic arms 220 are respectively arranged at both ends of the mounting piece 210. On the one hand, it is to ensure the balanced force of the elastic member 20 and the first connection head 310 of the MT ferrule 30 and improve the setting stability of the MT ferrule 30. At the same time, the distance between the two elastic arms 220 provides a space for the setting of the first connection head 310 and the optical fiber 40, realizing the installation of the MT ferrule 30 on the lower housing 120.

[0042] The process of arranging the MT ferrule 30 in the elastic mounting space is as follows:

[0043] Put the MT ferrule 30 into the lower housing 120, then place the mounting piece 210 of the elastic member 20 on the tops of the first side plate 123 and the second side plate 124, and make the elastic arms 220 abut against one end of the first connection head 310 away from the second connection head 320, and apply a force to the MT ferrule 30 to move it closer to the elastic arms 220, and place the second connection head 320 in the resisting arm 126, so that the MT ferrule 30 squeezes the elastic arms 220 to produce elastic deformation, completing the fixation of the MT ferrule 30.

[0044] Then buckle the upper housing 110 onto the lower housing 120 to make them buckle together, completing the setting of the MT ferrule 30 within the housing 10.

[0045] As a preferred solution of this embodiment, as Figure 3As shown in the figure, engaging grooves 125 are respectively formed on the outer walls of the first side plate 123 and the second side plate 124, and engaging blocks 113 are respectively arranged on both sides of the first mounting plate 111. The engaging blocks 113 can be engaged with the engaging grooves 125.

[0046] Among them, by inserting the engaging blocks 113 into the engaging grooves 125, the engaging grooves 125 and the engaging blocks 113 are cooperated to form an engaging structure, aiming to further strengthen the connection strength after the upper housing 110 and the lower housing 120 are buckled, improve the structural strength of the housing 10, provide a stable installation environment for the MT ferrule 30, ensure the coupling efficiency of the optical fiber 40, and improve the finished product qualification rate.

[0047] As a preferred solution of this embodiment, as Figure 2 shown in the figure, an abutting block 114 is arranged on one side of the first mounting plate 111 close to the second mounting plate 121.

[0048] Among them, by arranging the abutting block 114, it can cooperate with the second mounting plate 121 to form a limit for the MT ferrule 30 in the height direction of the housing 10, improve the setting stability of the MT ferrule 30 in the housing 10, ensure the coupling efficiency of the optical fiber 40 again, and improve the finished product qualification rate.

[0049] The size of the housing 10 in this embodiment can be adaptively adjusted according to the MT ferrule 30, and no specific limitation is made here.

[0050] This application embodiment also discloses a communication component 100, as Figures 5 to 7 shown in the figure, which includes an MT ferrule 30 and the fixed installation box in the above embodiment. The MT ferrule 30 is arranged in the installation cavity 101. The MT ferrule 30 includes a first connector 310 and a second connector 320 that are abutted. The first connector 310 is also elastically abutted against the free end of the elastic member 20, and the second connector 320 is also abutted against the housing 10 to fix the MT ferrule 30 in the elastic installation space.

[0051] This application embodiment also discloses an AOC optical module, as Figures 8 to 9 shown in the figure, which includes an upper cover 300, a lower cover 200 and the communication component 100 in the foregoing embodiment. The communication component 100 is arranged in the lower cover 200 and is located between the upper cover 300 and the lower cover 200.

[0052] The above communication component 100 and AOC optical module both include the same structure and beneficial effects as the fixed installation box in the foregoing embodiment. The structure and beneficial effects of the fixed installation box have been described in detail in the foregoing embodiment and will not be repeated here.
