[0024] Reference Figures 1 to 9 The present invention is implemented as follows: an LC adapter with an inner cover includes a frame housing 1 and a grounding plate 2 buckled with the frame housing 1. The frame housing 1 is provided with a front insertion port 11, a rear insertion port 12, and a connecting portion 13 connecting the front insertion port 11 and the rear insertion port 12. A ferrule 5 is installed in the connecting portion 13. A through hole 111 is provided at the bottom of the front insertion port 11. The grounding plate 2 is buckled with the bottom of the front insertion port 11 and covers the through hole 111. An elastic grounding structure 3 capable of interfering with the grounding plate 2 is installed at the opening of the front insertion port 11.
[0025] In this embodiment, the grounding plate 2 is buckled with the frame cover 1, and the grounding plate 2 covers the through hole 111, so that the grounding plate 2 does not occupy the space outside the frame cover 1, thereby achieving the purpose of effective space utilization. When there is no external force, the elastic grounding structure 3 blocks the opening of the front insertion port 11, preventing dust from entering the front insertion port 11, ensuring good signal transmission quality during connection. When the external plug is inserted into the front insertion port 11, as the external plug is inserted into the front insertion port 11, the elastic grounding structure 3 is tilted by the external plug and contacts the grounding plate 2, thereby achieving the purpose of grounding during the plug-in connection of the utility model.
[0026] Based on the above embodiment, as a further preferred embodiment, the bottom of the front insertion port 11 at the opening is provided with a frame strip 112 connected to the through hole 111, the bottom of the front insertion port 11 is provided with a recessed step 113 communicating with the through hole 111, the recessed step 113 partially extending to the frame strip 112, the bottom of the front insertion port 11 is provided with a rotating half-hole 114 and a positioning protrusion 115, the rotating half-hole 114 is provided on the side of the recessed step 113, the two inner side walls of the front insertion port 11 are provided with oblique steps 116, and the frame strip 112 is provided with a positioning through hole 111 communicating with the recessed step 113. When there is no external plug connection, the elastic grounding structure 3 prevents dust from entering the front insertion port 11.
[0027] The grounding plate 2 covers the outside of the through hole 111 and is confined in the recessed step 113. The elastic grounding structure 3 includes an inner cover 31 and an arc-shaped spring piece 32 fixedly clamped between the inner cover 31 and the grounding plate 2. The inner cover 31 is hinged to the rotating half socket 114. The head of the arc-shaped spring piece 32 contacts the inner cover 31. In the relaxed state, the inner cover 31 is stopped by the oblique step 116 and covers the inner side of the front insertion port 11.
[0028] The inner cover 31 includes an inner cover body 311, a rotation axis 312 fixedly connected to the inner cover body 311 and protruding from both sides of the inner cover body 311. The rotation axis 312 is hinged to the rotation half socket 114. The half side of the inner cover body 311 near the rotation axis 312 is provided with a protruding arc portion 3111 facing the inner side of the front insertion port 11. The arc-shaped spring piece 32 abuts against the side of the inner cover body 311 facing the protruding arc portion 3111. The arc-shaped spring piece 32 includes an arc-shaped body 321 and a positioning piece 322 fixedly connected to one end of the arc-shaped body 321. The arc-shaped body 321 is provided with a frame-shaped gap 323. The positioning piece 322 is provided with a positioning arc 324 with an arc that is connected to the rotation half socket 114. The positioning arc 324 is confined within the rotation half socket 114 and is fixedly clamped between the grounding plate 2 and the rotation axis 312.
[0029] The grounding plate 2 includes a grounding plate body 21 that is buckled with the frame sleeve 1 and a positioning portion 22 that is fixedly connected to the grounding plate body 21. The grounding plate body 21 covers the outside of the recessed step 113. The positioning portion 22 is provided with a clearance arc 221 with the same arc as the positioning arc 324. The positioning portion 22 is also provided with a positioning through hole 111. The bottom of the grounding plate body 21 is provided with a positioning groove 211 that engages with the positioning protrusion 115. The bottom of the grounding plate 2 is provided with a low-lying area 23 near the positioning portion 22.
[0030] When the inner cover 31 is assembled, the rotating shaft 312 of the inner cover 31 is hinged to the rotating half-socket 114. The elastic grounding plate 2 covers the outside of the inner cover 31. The inner cover body 311 is stopped by the inclined step 116 and covers the inside of the front insertion opening 11. Next, the curved spring piece 32 is assembled. The positioning piece 322 of the curved spring piece 32 covers the portion of the recessed step 113 on the frame bar 112, and the positioning arc 324 covers the outside of the rotating shaft 312 of the inner cover 31. The frame-shaped gap corresponds to the protruding arc portion 3111. Next, the grounding plate 2 is installed. The grounding plate body 21 covers the outside of the recessed step 113 and covers the through-hole 111. The positioning groove 211 at the bottom of the grounding plate body 21 engages with the positioning protrusion 115, and the positioning portion 22 is inserted into the positioning through-hole 111. After the grounding plate 2 is installed, the grounding plate 2 and the inner cover 31 confine the curved spring piece 32. The entire assembly is simple and convenient, and the overall structure is stable after assembly. When the external plug is inserted from the front insertion port 11, the external plug contacts the inner cover 31 and rotates around the rotation axis 312, thereby pushing the arc-shaped spring piece 32 to rotate around the positioning piece 322 until the arc-shaped body 321 of the arc-shaped spring piece 32 contacts the low-lying area 23. The inner cover 31 and the arc-shaped spring piece 32 are both made of conductive material. The external plug contacts the inner cover 31 and the arc-shaped spring piece 32 and then contacts the grounding plate 2 in an electrically conductive manner, thereby achieving the purpose of grounding.
[0031] When there is no external plug connection, the inner cover 31 is pushed by the head of the arc-shaped spring piece 32 toward the opening of the front insertion port 11 until the inclined step 116 stops the inner cover 31 to prevent dust from entering the front insertion port 11.
[0032] On the basis of the above embodiment, as a further preference, the connecting portion 13 includes a separation plate 131 arranged between the front insertion port 11 and the rear insertion port 12 and separating the front insertion port 11 and the rear insertion port 12. The separation plate 131 is provided with a front core seat 132 and a rear core seat 133 which pass through it and extend into the front insertion port 11 and the rear insertion port 12 at both ends respectively. The interiors of the front core seat 132 and the rear core seat 133 are both hollow and communicated with each other. The rear core seat 133 is set as a hollow cylinder. The core 5 is installed into the front core seat 132 and the rear core seat 133. The side wall of the rear core seat 133 is provided with a notch 1331.
[0033] The setting of the notch 1331 facilitates the opening of the hollow cylinder of the rear ferrule seat 133, increases its diameter, and facilitates the installation of the ferrule 5. After the ferrule 5 is installed, the ferrule 5 seat is loosened, and the notch 1331 of the rear ferrule seat 133 returns to its original shape, and the diameter is reduced and returns to the original diameter, ensuring the stability of the installation of the ferrule 5 in the front ferrule seat 132 and the rear ferrule seat 133.
[0034] It should be noted that the embodiment of the present invention adopts four-link as an implementation description. In fact, the present invention can be made into any number of links such as single link, double link, triple link, etc. with the same structure.
[0035] It should be noted that for the preferred implementation of the present utility model, ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present utility model, and these improvements and modifications should also be regarded as the scope of protection of the present utility model.
