[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides an embodiment: a double-connected optical fiber connection assembly, including a machine box 1 and an optical fiber connector body 4, arc-shaped protective edges are arranged on both sides of the optical fiber connector body 4, and the edges of the optical fiber connector body 4 can be protected. A connection port 2 is opened in the middle of one side of the machine box 1, and a connection plug 3 matching the connection port 2 is arranged on one side of the optical fiber connector body 4. A mounting groove 5 is arranged in the middle of the top of one side of the machine box 1, and protective plates 8 are sleeved at both ends of the inner side of the mounting groove 5, and coil springs 11 connected to the mounting groove 5 are arranged at both ends of the outer side of the protective plate 8;

[0025] Card slots 10 are provided at both ends of the bottom of the protective plate 8, and card strips 7 matching the card slots 10 are provided at both ends of the top of the optical fiber connector body 4. A plug hole 6 is provided in the middle of the top of the two groups of card strips 7, and a guide groove 12 is provided in the middle of the two ends of the top of the protective plate 8. The inner sides of the two groups of guide grooves 12 are sleeved with plug rods 13 matching the plug hole 6, and the outer sides of the two groups of plug rods 13 are sleeved with springs 9. A limit block is provided on the top of the outer side of the plug rod 13, and the bottom of the spring 9 is connected to the limit block. The range of motion of the plug rod 13 can be limited by the limit block.

[0026] Furthermore, a connecting plate is commonly provided at the top of the two groups of insertion rods 13, and a pulling block is provided in the middle of the top of the connecting plate. The connecting plate can be pulled by the pulling block to simultaneously drive the two groups of insertion rods 13 to move upward, thereby improving the convenience of disassembly.

[0027] Furthermore, the cross-sectional shape of the clamping strip 7 is dovetail-shaped, and the clamping slot 10 is matched with the clamping strip 7, so that after the optical fiber connector body 4 is connected, the clamping strip 7 can be inserted into the clamping slot 10 to connect and reinforce the optical fiber connector body 4.

[0028] Furthermore, sealing strips are provided at both ends of the bottom of the protective plate 8 , and the sealing strips can be used to enhance the dustproof sealing effect of the connection port 2 after the protective plate 8 is closed.

[0029] Working principle: When the device is connected, the protective plate 8 can be first turned 90 degrees to overcome the elastic force of the coil spring 11 to open the connection port 2, and then the connection plug 3 can be inserted into the connection port 2 for connection. At this time, the card strip 7 can be inserted into the card slot 10 at the bottom of the protective plate 8. Due to the shape characteristics of the plug rod 13, when the plug rod 13 is aligned with the socket 6, the elastic force of the spring 9 can push the plug rod 13 into the socket 6, and the optical fiber connector body 4 can be fixed. Through the connection between the mounting groove 5 and the optical fiber connector body 4, the stability of the optical fiber connector body 4 after connection can be enhanced to prevent the optical fiber connector body 4 from loosening and detaching;

[0030] When the fiber optic connector body 4 is pulled out, the connecting plate can be pulled by the pull block to drive the two sets of plug rods 13 to be pulled out from the insertion hole 6, thereby releasing the fixation of the fiber optic connector body 4. Then, the fiber optic connector body 4 can be pulled out. At this time, the elastic force of the coil spring 11 can be used to drive the protective plate 8 to flip and buckle into the outside of the connection port 2, thereby protecting the connection port 2 and preventing dust from entering the connection port 2 and damaging its internal circuit.
