Description

Technical Field

[0001] The utility model relates to the field of LC type adapters, in particular to an LC type adapter with built-in double plastic baffles. Background Art

[0002] In order to prevent the laser from damaging the eyes of the operators, the existing LC adapters often install a dust cap on the end of the LC adapter. However, the dust cap and the LC adapter are independently provided, and the dust cap is easy to lose. During the installation of the LC adapter, the dust cap needs to be removed, and then the optical fiber connector that matches the LC adapter is plugged in. During maintenance and inspection, when the optical fiber connector is pulled out of the LC adapter, the laser damages the naked eye. In addition, the LC adapter needs to be provided with structures such as a positioning part and a card board, so a relatively complex mold needs to be set to complete the injection molding.

[0003] Therefore, it is necessary to provide an LC adapter with built-in double plastic baffles to solve the above technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an LC type adapter with built-in double plastic baffles.

[0005] The utility model provides an LC adapter with built-in double plastic baffles, comprising a shell, wherein the upper and lower sides of the shell are respectively provided with mounting grooves, an upper cover and a lower cover are provided in the mounting grooves, and the upper cover and the lower cover are both clamped and fixed with the shell, a light channel is provided in the shell, a ceramic sleeve is fixed at one end of the light channel, a limiting plate is provided inside the other end of the shell, a receiving groove is provided between the limiting plate and the lower cover, a spring is provided in the receiving groove, and one end of the spring is located in the light channel.

[0006] Preferably, a first card plate is provided at the bottom of the upper cover, and a first card slot for engaging with the first card plate is provided in the shell.

[0007] Preferably, a positioning plate is provided at one end of the lower cover, a positioning groove cooperating with the positioning plate is provided on the inner wall of the shell, a second clamping plate is provided at the other end of the lower cover, and a second clamping groove cooperating with the second clamping plate is provided in the shell.

[0008] Preferably, the housing, the upper cover and the lower cover are all provided with positioning parts.

[0009] Preferably, both the upper cover and the lower cover are provided with a connecting card plate, and the connecting card plate is integrally arranged with the upper cover and the lower cover.

[0010] Compared with the related art, the utility model provides the following beneficial effects:

[0011] When the fiber optic connector is inserted into the LC adapter, the reed will bend to avoid it. When the fiber optic connector is pulled out of the LC adapter, the reed will return to its original position to block the light channel again. By setting the reed, the light channel can be blocked to prevent laser damage to the eyes of operators.

[0012] By independently setting the upper cover and the lower cover and the shell and then assembling them, the difficulty of mold opening and mold manufacturing can be reduced, and the reed can be effectively fixed by setting the lower cover. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0016] Please refer to Figure 1 , an LC adapter with built-in double plastic baffles, comprising a shell 1, wherein the upper and lower sides of the shell 1 are respectively provided with mounting grooves 2, wherein an upper cover 3 and a lower cover 4 are arranged in the mounting groove 2, and the upper cover 3 and the lower cover 4 are both fixed with the shell 1 by snapping, wherein a light channel 5 is arranged in the shell 1, wherein a ceramic sleeve 6 is fixed at one end of the light channel 5, wherein a limiting plate 7 is arranged inside the other end of the shell 1, wherein a receiving groove 8 is arranged between the limiting plate 7 and the lower cover 4, wherein a spring 9 is arranged in the receiving groove 8, and wherein one end of the spring 9 is located in the light channel 5.

[0017] A first clamping plate 10 is provided at the bottom of the upper cover 3 , and a first clamping groove which is clamped and matched with the first clamping plate 10 is provided in the shell 1 . The upper cover 3 is clamped and fixed to the shell 1 by the clamping cooperation between the first clamping plate 10 and the first clamping groove.

[0018] A positioning plate 12 is provided at one end of the lower cover 4, and a positioning groove 13 is provided on the inner wall of the shell 1 to cooperate with the positioning plate 12. Through the arrangement of the positioning plate 12 and the positioning groove 13, when installing the lower cover 4, the lower cover 4 is placed in the installation groove 2, and the lower cover 4 is pushed to make the lower cover 4 slide relative to the shell 1. When the positioning plate 12 moves to the positioning groove 13, the second clamping plate 14 is clamped in the second clamping groove, so that the shell 1 and the lower cover 4 are clamped and fixed. The other end of the lower cover 4 is provided with a second clamping plate 14, and a second clamping groove is provided in the shell 1 to clamp and cooperate with the second clamping plate 14.
