[0023] Reference Figure 1 , Figure 2 and Figure 3The embodiment of the present invention provides an FTTR gateway device, including a housing 1, a guide rod, a first guide bar 41, a second guide bar 43, and a coupler 2; the housing 1 is provided with a socket 16 and a plurality of positioning rods 11, the socket 16 connects the inner cavity of the housing 1 with the outside, and the positioning rods 11 extend in the front-rear direction; A plurality of positioning holes 21 are provided in the middle of the coupler 2, and the plurality of positioning holes 21 correspond to the positioning rods 11 one by one, and each positioning rod 11 is plugged into the corresponding positioning hole 21, and the coupler 2 is provided with the socket 16, and the front end of the coupler 2 passes through the housing 1 from the socket 16; The first guide bar 41 and the second guide bar 43 are both arranged on the shell 1, the first guide bar 41 is located on the left side of the coupler 2, and the second guide bar 43 is located on the right side of the coupler 2. The rear end of the first guide bar 41 is spaced apart from the coupler 2, and the rear end of the second guide bar 43 is spaced apart from the coupler 2. The first guide bar 41 and the second guide bar 43 gradually approach the coupler 2 from back to front, and the side of the front end of the first guide bar 41 close to the coupler 2 is flush with the left side wall of the socket 16, and the side of the front end of the second guide bar 43 close to the coupler 2 is flush with the right side wall of the socket 16, so that the coupler is directly aligned with the socket from the front end of the first guide bar and the front end of the second guide bar.

[0024] When assembling the coupler 2 (flange) in this embodiment, the coupler 2 is first placed on the bottom of the housing 1, and then the coupler 2 is pushed in the front-to-back direction until the front end of the coupler 2 is inserted into the socket 16. During the pushing process of the coupler 2, the front end of the coupler 2 enters the gap between the first guide bar 41 and the second guide bar 43. The first guide bar 41 and the second guide bar 43 guide the coupler 2 forward. Even if the front end of the coupler 2 is offset, the surface of the first guide bar 41 and the surface of the second guide bar 43 can limit the excessive offset of the coupler 2. Since the gap between the first guide bar 41 and the second guide bar 43 gradually shrinks and the gap between the two is equal to the gap between the left and right side walls of the socket 16, the guided coupler 2 smoothly enters the socket 16.

[0025] Compared with the prior art, this embodiment guides the forward direction of the coupler 2 entering the socket 16 through the first guide bar 41 and the second guide bar 43, so that the coupler 2 can smoothly enter the socket 16. During the guiding process, there is no need for personnel to always pay attention to whether the positioning hole 21 and the positioning rod 11 are aligned. The coupler 2 only needs to be pushed forward into the socket 16 along the bottom surface of the shell 1 by the assembler, thereby improving the assembly efficiency.

[0026] As an example, the FTTR gateway device further includes a first track bar 42 and a second track bar 44, one end of the first track bar 42 is connected to the front end of the first guide bar 41, the other end of the first track bar 42 is connected to the left side wall of the socket 16, and the surface of the first track bar 42 close to the coupler 2 is flush with the left side wall of the socket 16; One end of the second track bar 44 is connected to the front end of the first guide bar 41 , and the other end of the second track bar 44 is connected to the right side wall of the socket 16 . The surface of the second track bar 44 close to the coupler 2 is flush with the right side wall of the socket 16 .

[0027] In this embodiment, the housing 1, the first track bar 42 and the first guide bar 41 are integrally formed. Due to the existence of the first track bar 42, the coupler 2 is guided throughout the process of entering the socket 16, thereby further improving the assembly efficiency. The second track bar 44 is similar to the first track bar 42 and will not be described in detail here.

[0028] As an example, the FTTR gateway device also includes a first mounting plate 12 and a second mounting plate 13 arranged on the shell 1, the first mounting plate 12 and the second mounting plate 13 extend in the up and down directions, part of the positioning rod 11 is arranged on the first mounting plate 12, and the other part of the positioning rod 11 is arranged on the second mounting plate 13.

[0029] In this embodiment, the positioning rod 11, the mounting plate and the housing 1 are integrally formed, two positioning holes 21 are provided, one positioning hole 21 is provided on each of the left and right sides of the coupler 2, and two positioning rods 11 are provided accordingly, one positioning rod 11 is provided on the first mounting plate 12, and the other positioning rod 11 is provided on the second mounting plate 13. The positioning rod 11 extends backward, and the positioning rod 11 is plugged into the positioning hole 21 on the coupler 2.

[0030] As an example, the rear end of the first guide bar 41 is connected to the first mounting plate 12; the rear end of the second guide bar 43 is connected to the second mounting plate 13. In this embodiment, the first guide bar 41 is connected to the first mounting plate 12 so that there is no gap between the first guide bar 41 and the first mounting plate 12, thereby preventing the coupler 2 from being stuck in the gap between the first guide bar 41 and the first mounting plate 12 during the insertion process of the socket 16. The principle of the connection between the second guide bar 43 and the second mounting plate 13 is the same as the principle of the connection between the first guide bar 41 and the first mounting plate 12, and will not be described in detail.

[0031] As an example, a first elastic sheet 22 and a second elastic sheet 23 are provided in the middle of the coupler 2, the front end of the first elastic sheet 22 is fixed on the coupler 2, the rear end of the first elastic sheet 22 is spaced apart from the coupler 2, and the rear end of the first elastic sheet 22 has a tendency to move away from the coupler 2, so that the first elastic sheet 22 abuts against a side surface of the first mounting plate 12 close to the socket 16. The front end of the second elastic sheet 23 is fixed on the coupler 2, the rear end of the second elastic sheet 23 is spaced apart from the coupler 2, and the rear end of the second elastic sheet 23 has a tendency to move away from the coupler 2, so that the second elastic sheet 23 abuts against a side surface of the second mounting plate 13 close to the socket 16.

[0032] At present, many couplers 2 are provided with metal springs on the left and right sides, that is, a first spring 22 is provided on the left side of the coupler 2, and a second spring 23 is provided on the right side of the coupler 2. After the coupler 2 is inserted into the socket 16, the first spring 22 abuts against the first mounting plate 12 and the second spring 23 abuts against the second mounting plate 13, which plays a role in preventing the coupler 2 from retreating, and prevents the coupler 2 from retreating when an external device is inserted into the coupler 2. Therefore, the first mounting plate 12 in this embodiment is not only a mounting base for the positioning rod 11, but also plays a role in preventing the first spring 22 from retreating. The same is true for the second spring 23 and the second mounting plate 13, which will not be described here. In short, the first spring 22 and the second spring 23 prevent the coupler 2 from retreating from both sides, ensuring that the position of the coupler 2 is stable and does not shake arbitrarily.

[0033] As an example, the rear end of the first guide bar 41 and the side of the first mounting plate 12 close to the coupler 2 are spaced apart, and the distance between the rear end of the first guide bar 41 and the side of the first mounting plate 12 close to the coupler 2 is greater than the distance between the rear end of the first elastic sheet 22 and the coupler 2; In some embodiments, since the first spring sheet 22 is a metal spring sheet and is elastic, when the first spring sheet 22 is deformed in the left and right directions, it may touch the first guide bar 41 and may bend. Therefore, in this embodiment, the distance between the rear end of the first spring sheet 22 and the side surface of the first mounting plate 12 close to the coupler 2 is enlarged to leave enough space for the first spring sheet 22 to deform.

[0034] In the left-right direction, the rear end of the second guide bar 43 and the side of the second mounting plate 13 close to the coupler 2 are spaced apart, and the distance between the rear end of the second guide bar 43 and the side of the second mounting plate 13 close to the coupler 2 is greater than the distance between the rear end of the second elastic sheet 23 and the coupler 2. Similarly, the rear end of the first guide bar 41 and the surface of the first mounting plate 12 close to the coupler 2 are spaced apart, which will not be described in detail.

[0035] Reference Figure 4 As an example, the upper surface of the first guide bar 41 and the lower surface of the first spring sheet 22 are spaced apart, and the first spring sheet 22 is located above the first guide bar 41; the upper surface of the second guide bar 43 and the lower surface of the second spring sheet 23 are spaced apart, and the second spring sheet 23 is located above the second guide bar 43.

[0036] In the up-down direction, the upper surface of the first guide bar 41 and the lower surface of the first elastic sheet 22 are spaced apart, and the first elastic sheet 22 is located above the first guide bar 41, mainly to avoid the first elastic sheet 22 from rubbing against the first guide bar 41 during the deformation process, thereby causing the first elastic sheet 22 to be bent and damaged. Similarly, the second guide bar 43 and the second elastic sheet 23 are also spaced apart, which will not be described in detail.

[0037] As an example, a side surface of the first mounting plate 12 close to the coupler 2 gradually moves away from the coupler 2 from front to back; a side surface of the second mounting plate 13 close to the coupler 2 gradually moves away from the coupler 2 from front to back.

[0038] Reference Figure 2 In this embodiment, a side surface of the first mounting plate 12 close to the coupler 2 includes a first inclined surface 122 and a first plane 121, the first plane 121 is perpendicular to the rear end surface of the first mounting plate 12, the first inclined surface 122 connects the first plane 121 and the front end surface of the first mounting plate 12, and the first inclined surface 122 gradually approaches the coupler 2 from front to back; a side surface of the second mounting plate 13 close to the coupler 2 includes a second inclined surface 132 and a second plane 131, the second plane 131 is perpendicular to the rear end surface of the second mounting plate 13, the second inclined surface 132 connects the second plane 131 and the front end surface of the second mounting plate 13, and the second inclined surface 132 gradually approaches the coupler 2 from front to back. When replacing or repairing the coupler 2, the maintenance personnel squeeze the first elastic sheet 22 and the second elastic sheet 23 toward the coupler 2, so that the first elastic sheet 22 and the second elastic sheet 23 are close to the coupler 2. At this time, the distance between the end of the first elastic sheet 22 and the coupler 2 is reduced or even zero, and the distance between the end of the second elastic sheet 23 and the coupler 2 is reduced or even zero, and the coupler 2 is pulled out backward. When the coupler 2 is pulled out, due to the existence of the first inclined surface 122, the interference of the first mounting plate 12 on the action of pulling out the coupler 2 is reduced, and the second inclined surface 132 reduces the interference of the second mounting plate 13 on the action of pulling out the coupler 2, thereby accelerating the efficiency of repairing or replacing the coupler 2.

[0039] Reference Figure 1 and Figure 2As an example, the FTTR gateway device further includes a plurality of first reinforcing ribs 14 and second reinforcing ribs 15, wherein the first reinforcing ribs 14 connect the first mounting plate 12 and the housing 1, and the second reinforcing ribs 15 connect the second mounting plate 13 and the housing 1. In this embodiment, two first reinforcing ribs 14 and two second reinforcing ribs 15 are respectively provided, and the two first reinforcing ribs 14 are provided on the rear end surface of the first mounting plate 12 to reinforce the first reinforcing ribs 14. The two second reinforcing ribs 15 are provided on the rear end surface of the second mounting plate 13 to reinforce the second reinforcing ribs 15.

[0040] As an example, the first guide bar 41, the second guide bar 43, the guide rod and the housing 1 are integrally formed. The FTTR gateway device in this embodiment can be a FTTR router, the housing 1 is the housing 1 of the router, and the coupler is a flange in this field. The main function of the flange is to distribute optical signals from one optical fiber to multiple optical fibers, or to merge optical signals of multiple optical fibers into one optical fiber. There are many types of couplers, including SC fiber couplers suitable for SC fiber interfaces, and LC fiber couplers used for LC fiber interfaces. The housing 1 in this embodiment is made of plastic.
