[0033] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] The structure of automobiles is complex. In order to pursue the ultimate space, on-board devices are often modularized and integrated, leaving very little space for optical fiber layout. At the same time, optical fibers are fragile and easy to break. The driving environment of automobiles is complicated and the slightest carelessness may cause damage to the optical fibers. Therefore, a series of protective measures are required for the optical fibers, such as cable sheath wrapping, firm fixation, and shell protection. These protective measures will undoubtedly increase the size of the optical module unit. How to minimize the size of the on-board splitter box by reasonably laying out the optical fiber and adjusting the fiber routing structure is an important issue that needs to be solved in the development of the optical cable on-board business.

[0035] The embodiment of the present application provides a splitter box, which can solve the technical problem in the related art that the currently large-volume optical fiber box is not suitable for vehicle-mounted optical fiber layout.

[0036] See also Figure 1As shown, a spectrometer box provided in an embodiment of the present application may include: a box body 1c, wherein a positioning boss 2c is provided in the box body 1c, wherein the positioning boss 2c and the inner wall of the box body 1c form a plurality of fiber-running channels; an adapter 3c, wherein the adapter 3c is positioned on the positioning boss 2c, and the adapter 3c and at least a portion of the fiber-running channels are stacked along the thickness direction of the box body 1c.

[0037] In this embodiment, the box body 1c includes a base 11c and a box cover 12c, and the base 11c and the box cover 12c can be fixed together in a detachable manner such as bolts, so that the box cover 12c can be opened, which is convenient for operation in the base 11c. The above-mentioned positioning boss 2c and adapter 3c are both installed in the base 11c, wherein the positioning boss 2c is preferably integrally formed on the inner bottom wall of the base 11c, and the adapter 3c is clamped on the positioning boss 2c, and the positioning boss 2c can position the adapter 3c at a preset position of the base 11c; at the same time, the surrounding of the positioning boss 2c also forms a plurality of fiber-running channels with the inner wall of the box body 1c to provide space for the winding of the pigtail 9c. It can be understood that the above-mentioned thickness direction is also the direction in which the box cover 12c is installed to the base 11c. If the base 11c is placed horizontally, the thickness direction is also the up and down direction (also the height direction of the box body 1c).

[0038] In this embodiment, by setting a positioning boss 2c in the box body 1c, the positioning boss 2c is not only used to position the adapter 3c, but also the positioning boss 2c can define a fiber path in the box body 1c together with the inner wall of the box body 1c, and there is no need to set up additional other structures to define the fiber path, reducing the redundant structure in the box body 1c, and making the splitter box small and compact. At the same time, at least a part of the fiber path is stacked and arranged up and down with the adapter 3c in space, making full use of the space under the adapter 3c to form the fiber path, saving the fiber coil space in the splitter box, making the internal structure of the splitter box more compact, and further reducing the volume of the splitter box. In this embodiment, the volume of the splitter box is minimized by reasonably arranging the fiber path, so that the splitter box can be used in cars with limited space, solving the technical problem that the currently large-volume fiber optic box in the related art is not suitable for vehicle-mounted fiber optic layout.

[0039] Further, in one embodiment, see Figure 3As shown, the multiple fiber routing channels include a same-direction channel 4c and a reversing channel 5c; the surrounding areas of the positioning boss 2c and the inner wall of the box body 1c form the same-direction channel 4c, the interior of the positioning boss 2c forms the reversing channel 5c, and both ends of the reversing channel 5c are connected to the same-direction channel 4c; and the reversing channel 5c and at least part of the same-direction channel 4c are stacked with the adapter 3c along the thickness direction of the box body 1c. In the present embodiment, the four sides of the positioning boss 2c and the inner wall of the box body 1c form a ring-shaped same-direction channel 4c. The same-direction channel 4c can be a complete ring, or can be set to a semi-ring structure according to actual needs. The pigtail 9c can be coiled in the same direction in the same-direction channel 4c. In addition to the same-direction channel 4c, the present embodiment is also provided with a reversing channel 5c. The connection between one end of the reversing channel 5c and the same-direction channel 4c is a diversion point. After winding along the same-direction channel 4c to the diversion point, part of the pigtail 9c can enter the reversing channel 5c. After passing through the reversing channel 5c, the winding direction of the pigtail 9c can be reversed, so that the winding direction of the part of the pigtail 9c is opposite to the winding direction of the other part of the pigtail 9c.

[0040] In this embodiment, a row of adapters 3c can be positioned on the positioning boss 2c, and the unidirectional channel 4c surrounds the adapter 3c. After the pigtail 9c is coiled in the fiber routing channel, one end of the pigtail 9c is finally inserted into the adapter 3c, and one end of each adapter 3c is correspondingly inserted with a pigtail 9c. In this embodiment, by providing a reversing channel 5c whose two ends are connected to the unidirectional channel 4c, the winding direction of some pigtails 9c can be reversed, so that some pigtails 9c are coiled from the left side of a row of adapters 3c to the front of a row of adapters 3c, and other pigtails 9c are coiled from the right side of a row of adapters 3c to the front of a row of adapters 3c, thereby solving the problem that all pigtails 9c are coiled in the same direction to the front of the adapter 3c, resulting in insufficient winding radius of the optical fiber on that side (for example, all pigtails 9c are routed in a counterclockwise direction from the right side of a row of adapters 3c, resulting in insufficient winding radius of the rightmost optical fiber).

[0041] Further, in some embodiments, see Figure 3 and Figure 4As shown, the same-direction channel 4c includes a first fiber channel 41c, a second fiber channel 42c, a third fiber channel 43c and a fourth fiber channel 44c; the four sides of the positioning boss 2c are respectively connected with the four inner walls of the box body 1c to form the first fiber channel 41c, the second fiber channel 42c, the third fiber channel 43c and the fourth fiber channel 44c which are connected in sequence; the two ends of the reversing channel 5c are respectively connected to the first fiber channel 41c and the third fiber channel 43c, the second fiber channel 42c, the reversing channel 5c and the fourth fiber channel 44c are arranged side by side, and the second fiber channel 42c and the reversing channel 5c are stacked with the adapter 3c along the thickness direction of the box body 1c.

[0042] See also Figure 2 and Figure 3 As shown, the positioning boss 2c includes a first positioning boss 21c and a second positioning boss 22c, a first fiber walking channel 41c is formed between the left side of the first positioning boss 21c and the second positioning boss 22c and the left inner wall of the box body 1c, a second fiber walking channel 42c is formed between the rear side of the second positioning boss 22c and the rear inner wall of the box body 1c, a third fiber walking channel 43c is formed between the right side of the first positioning boss 21c and the second positioning boss 22c and the right inner wall of the box body 1c, and a fourth fiber walking channel 44c is formed between the front side of the first positioning boss 21c and the front inner wall of the box body 1c; the first fiber walking channel 41c, the second fiber walking channel 42c, the third fiber walking channel 43c and the fourth fiber walking channel 44c are connected end to end, and the reversing channel 5c is located between the second fiber walking channel 42c and the fourth fiber walking channel 44c, the left end of the reversing channel 5c is connected to the first fiber walking channel 41c, and the right end is connected to the third fiber walking channel 43c. In this embodiment, the second fiber-running channel 42c and the reversing channel 5c are both located below the adapter 3c, and the space below a row of adapters 3c is fully utilized to form two longitudinal channels.

[0043] See also Figure 6 and Figure 7 As shown, in this embodiment, n pigtails 9c can pass through the first fiber channel 41c and the second fiber channel 42c to reach the diversion point of the third fiber channel 43c, among which n / 2 pigtails 9c can be separated to reach the front end of several adapters 3c on the left side through the third fiber channel 43c and the fourth fiber channel 44c; in addition, n / 2 pigtails 9c are changed through the reversing channel 5c, and then reach several adapters 3c on the right side through the first fiber channel 41c and the fourth fiber channel 44c, so as to solve the problem of insufficient winding radius of the rightmost fiber caused by the fiber only running from the right side. In addition, this embodiment performs diversion management on the pigtails 9c, and all pigtails 9c meet the minimum winding radius requirement, which can minimize the risk of excessive optical loss and fiber breakage while ensuring the compact space in the splitter box.

[0044] See also Figure 2 As shown, a fiber blocking plate 8c may be further provided in the reversing channel 5c and the second fiber running channel 42c to ensure that the pigtail 9c does not warp in the channel.

[0045] Further, in one embodiment, see Figure 3 and Figure 4 As shown, the positioning boss 2c includes a first positioning boss 21c and a second positioning boss 22c that are spaced apart, the first positioning boss 21c and the second positioning boss 22c both extend from the first fiber routing channel 41c to the third fiber routing channel 43c, and the reversing channel 5c is formed between the first positioning boss 21c and the second positioning boss 22c; a plurality of the adapters 3c are positioned on the first positioning boss 21c and the second positioning boss 22c, and the axis of the adapter 3c extends along the arrangement direction of the second fiber routing channel 42c and the reversing channel 5c.

[0046] In this embodiment, the first positioning boss 21c and the second positioning boss 22c are both long strips, extending from the left side to the right side of the box body 1c, so that a longitudinal reversing channel 5c is formed between the first positioning boss 21c and the second positioning boss 22c. Each adapter 3c is positioned by the first positioning boss 21c and the second positioning boss 22c. A row of groove structures are provided on the first positioning boss 21c and the second positioning boss 22c. The front part of each adapter 3c is positioned in the groove structure of the first positioning boss 21c, and the rear part is positioned in the groove structure of the second positioning boss 22c. A row of adapters 3c are arranged side by side along the left and right direction of the box body 1c, and the axis of each adapter 3c is along the front-to-back direction. Preferably, the axis of the adapter 3c is perpendicular to the first positioning boss 21c. Of course, the adapter 3c can also be tilted on the first positioning boss 21c and the second positioning boss 22c, so that the adapter 3c is tilted along the front-to-back direction. In this embodiment, multiple adapters 3c are arranged along the longitudinal direction of the second fiber running channel 42c and the reversing channel 5c, which not only allows multiple adapters 3c to be arranged in the box body 1c so that the adapters 3c are compactly distributed side by side, but also ensures that the multiple adapters 3c have a larger overlapping area with the second fiber running channel 42c and the reversing channel 5c in the up and down direction.

[0047] Further, in some embodiments, see Figure 5 As shown, a splitter 6c is arranged in one of the fiber-running channels. In this embodiment, the splitter 6c is preferably arranged in the fourth fiber-running channel 44c, and the extension direction of the splitter 6c is the same as the extension direction of the fourth fiber-running channel 44c, so that the space of the fourth fiber-running channel 44c can be fully utilized, and the splitter 6c can be arranged in addition to fiber-running, thereby saving space and improving space utilization.

[0048] On the basis of the above technical solution, in a preferred embodiment, the same end of the splitter 6c is provided with an optical fiber inlet 61c and an optical fiber outlet 62c. In this embodiment, the left end of the splitter 6c is provided with both an optical fiber inlet 61c and an optical fiber outlet 62c. Figure 8 As shown, there is one optical fiber inlet 61c and four optical fiber outlets 62c, and the optical fiber inlet 61c can be installed with an inlet connector, and the optical fiber outlet 62c can be installed with an outlet connector. The splitter 6c of this embodiment adopts a single-side fiber inlet and outlet structure, so that only the optical fiber storage space at one end of the splitter 6c is reserved in the box body 1c, and the other side of the splitter 6c can be placed against the wall, which can save the internal space of the box body 1c and make the splitter box more compact.

[0049] Of course, in other embodiments, a splitter 6c with fiber input at one side and fiber output at the other side may also be selected, and this is not limited here.

[0050] Further, in one embodiment, see Figure 8 As shown, the splitter 6c is provided with a plurality of optical fiber outlets 62c, and the plurality of optical fiber outlets 62c and the optical fiber inlet 61c are arranged at the same end of the splitter 6c along the thickness direction of the box body 1c. In this embodiment, preferably, four optical fiber outlets 62c and one optical fiber inlet 61c are provided, and the four optical fiber outlets 62c are arranged in a row, and the optical fiber inlet 61c is provided above the row of optical fiber outlets 62c. Such a configuration can reduce the width of the splitter 6c in the front-to-back direction, and reserve more space for the storage of the pigtail 9c.

[0051] Further, in some optional embodiments, a fixing groove 7c is provided in the box body 1c, the splitter 6c is inserted into the fixing groove 7c along its axial direction, and one end of the splitter 6c away from the optical fiber inlet 61c is in contact with the inner wall of the box body 1c. In this embodiment, the fixing groove 7c can enclose the installation cavity of the splitter 6c together with the inner wall of the box body 1c. Since the splitter 6c adopts a single-side fiber inlet and outlet structure, the splitter 6c can be inserted into the fixing groove 7c along its axial direction until the right end of the splitter 6c is in contact with the inner wall of the box body 1c. When assembling the splitter 6c, only one direction of track space needs to be reserved. In addition to the direction in which the splitter 6c is inserted into the fixing groove 7c, the remaining five directions can be used as the limit structure and fiber blocking structure of the splitter 6c, which makes the optical fiber positioning more convenient, the splitter box design more flexible, and the assembly of the splitter 6c more flexible. In other embodiments, if other structural components need to be provided on the right side of the splitter 6c, the right side of the splitter 6c may not be attached to the inner wall of the box body 1c.

[0052] In the related art, the splitter 6c generally adopts a double-sided fiber outlet structure (i.e., one side of the fiber is fed in and the other side of the fiber is output). Limited by the double-sided fiber outlet structure of the splitter 6c, the splitter 6c can only be assembled by cutting in horizontally. When designing the main structure of the box, it is necessary to reserve a plane movement space for the splitter 6c. Other feature designs cannot be performed in this space, resulting in space waste. The single-sided fiber outlet structure of the splitter 6c in this embodiment can greatly save space in the box body 1c.

[0053] Further, in one embodiment, see Figure 6 and Figure 7 As shown, a fiber blocking plate 8c is also provided in the fiber-walking channel where the splitter 6c is arranged, and the fiber blocking plate 8c and the splitter 6c are stacked along the thickness direction of the box body 1c, and there is a gap between the fiber blocking plate 8c and the splitter 6c. In this embodiment, a fiber blocking plate 8c is provided above the splitter 6c, and the fiber blocking plate 8c and the splitter 6c are arranged at an interval up and down, so that the gap between the fiber blocking plate 8c and the splitter 6c can allow the pigtail 9c to pass, and the fiber blocking plate 8c can limit the pigtail 9c in the vertical direction to ensure that the pigtail 9c does not warp.

[0054] See also Figures 5 to 7 As shown, in this embodiment, five adapters 3c are provided on the positioning boss 2c as an example for explanation. Among the five adapters 3c, the leftmost adapter 3c is a fiber-in adapter 3c, and the remaining four adapters 3c are fiber-out adapters 3c. The fiber-in adapter 3c can be connected to the fiber inlet 61c of the splitter 6c through a pigtail 9c, and the four fiber outlets 62c of the splitter 6c can be connected to the remaining four fiber-out adapters 3c through four pigtails 9c respectively; wherein, see Figure 6 As shown, the four pigtails 9c coming out of the optical fiber outlet 62c first enter the first fiber channel 41c, then enter the second fiber channel 42c under the row of adapters 3c, and then reach the branching point of the third fiber channel 43c, wherein two pigtails 9c can be separated and redirected through the reversing channel 5c, and then inserted into the two rightmost adapters 3c through the first fiber channel 41c and the fourth fiber channel 44c; see Figure 7 As shown, the other two pigtails 9c pass through the third fiber routing channel 43c and the fourth fiber routing channel 44c to reach the two adapters 3c inserted on the left side. Routing the fibers in this way can avoid the problem that all four pigtails 9c enter the fourth fiber routing channel 44c from the third fiber routing channel 43c, resulting in insufficient coiling radius of the pigtails 9c inserted into the two rightmost adapters 3c. Through this fiber routing structure, the space of the box body 1c can be maximized while ensuring the inner diameter of the pigtail 9c coil.

[0055] The embodiment of the present application also provides another splitter box, which may include: a box body 1c, wherein a positioning boss 2c is provided in the box body 1c, wherein the positioning boss 2c and the inner wall of the box body 1c form a plurality of fiber paths; an adapter 3c, wherein the adapter 3c is positioned on the positioning boss 2c, and the adapter 3c and at least part of the fiber paths are stacked along the thickness direction of the box body 1c; a splitter 6c, wherein the splitter 6c is connected to a pigtail 9c, wherein one end of the pigtail 9c is connected to the splitter 6c, and the other end is coiled to the adapter 3c through the fiber paths, and plugged into the adapter 3c. The box body 1c in this embodiment may adopt the box body 1c provided in any of the above embodiments, and the splitter 6c may adopt the splitter 6c provided in any of the above embodiments, and realize the corresponding functions, which will not be described in detail here.
