Description

Technical Field

[0001] This utility model belongs to the field of USB connector technology, and relates to electromagnetic interference, specifically an electromagnetic interference-resistant structure for a USB connector female socket. Background Technology

[0002] The electromagnetic interference (EMI) protection structure of USB female connectors is designed to reduce the impact of external EMI on data transmission and decrease the connector's own electromagnetic radiation. To achieve this, USB female connectors typically employ a metal shielding shell to block external electromagnetic waves and prevent signal leakage, while internal grounding pins enhance EMI immunity. Furthermore, some advanced connectors integrate EMI filters or capacitors to suppress high-frequency noise, and twisted-pair cables effectively reduce signal crosstalk. Physical isolation and optimized material design are also crucial measures for reducing interference. Through these designs, USB female connectors effectively resist EMI, ensuring the stability and reliability of data transmission.

[0003] The electromagnetic interference (EMI) protection structures of some existing USB connector female sockets are relatively simple and may not be able to effectively cope with complex electromagnetic environments, especially in high-interference situations. Therefore, this problem needs to be solved. Utility Model Content

Two shielding outer plates 201 are symmetrically rotatably connected to one side of the main body 1. Two adjusting posts 202 are symmetrically fixedly connected to one end of each of the two shielding outer plates 201. A first rotating shaft 203 is fixedly connected to the end of each of the two shielding outer plates 201 away from the two adjusting posts 202. An adjusting mechanism for adjusting the shielding outer plates 201 is provided on the surface of each of the two first rotating shafts 203 away from the shielding outer plates 201. Side plates 211 are fixedly connected to both sides of the shielding outer shell 2. A constraint mechanism for constraining the shielding outer plates 201 is provided on one side of each of the two side plates 211. The shielding inner plate 101, shielding outer shell 2, and shielding outer plates 201 can enhance the protection of the main body 1.

[0021] Preferably, the adjustment mechanism includes a slide groove 206, which is formed inside the shielding shell 2. Two limiting rods 207 are symmetrically fixedly connected inside the slide groove 206. The same slider 209 is slidably sleeved on the surface of the two limiting rods 207. The surface of each of the two limiting rods 207 is provided with a reset mechanism for resetting the slider 209. A first mounting groove 210 is formed at the top of the slider 209. A first rotating shaft 203 is rotatably connected inside the first mounting groove 210. A first support column 204 is fixedly connected to the bottom of the first rotating shaft 203. A first torsion spring 205 is sleeved on the surface of the first support column 204. The shielding outer plate 201 can be reset by the setting of the first torsion spring 205. The top end of the first torsion spring 205 is fixedly connected to the bottom of the first rotating shaft 203, and the bottom end of the first torsion spring 205 is fixedly connected to the inside of the first mounting groove 210. The shielding outer plate 201 can be moved by the setting of the slider 209.

[0022] Furthermore, the reset mechanism includes a spring 208, which is sleeved on the surface of the limiting rod 207. One end of the spring 208 is fixedly connected to one side of the slider 209, and the other end of the spring 208 is fixedly connected to one side of the slide groove 206. By setting the spring 208, the slider 209 can be reset.

[0023] Preferably, the constraint mechanism includes two second mounting slots 212, which are located at both ends of the side plate 211. A second rotating shaft 302 is rotatably connected inside each of the two second mounting slots 212. A pull plate 3 is fixedly connected to the surface of each second rotating shaft 302 away from the side plate 211. Two clamping plates 301 are symmetrically fixedly connected to the surface of the pull plate 3 near the adjusting column 202, and both clamping plates 301 are configured to cooperate with the adjusting column 202. A second support column 303 is fixedly connected to the surface of each of the two second rotating shafts 302 near the side plate 211. A second torsion spring 304 is sleeved on the surface of each of the two second support columns 303. The clamping plates 304 allow the clamping plates 301 to be reset. One end of each second torsion spring 304 is fixedly connected to the bottom of the second rotating shaft 302, and the other end is fixedly connected to the inside of the second mounting slot 212. The clamping plates 301 constrain the outer shielding plate 201.

[0024] Working principle: In use, the outer shielding plate 201 is first rotated by the adjusting column 202. A first rotating shaft 203 is installed at one end of the outer shielding plate 201, and the first rotating shaft 203 cooperates with the slider 209 inside the shielding shell 2. Thus, the outer shielding plate 201 will rotate around the first rotating shaft 203 as the center. After the outer shielding plate 201 has rotated, it is inserted into the shielding shell 2. A retaining plate 301 is installed at both ends of the shielding shell 2, and one end of the retaining plate 301 is inclined. Therefore, when the outer shielding plate 201 moves the adjusting column 202, the adjusting column 202 will move the retaining plate 301. 01 is squeezed to rotate it. After the clamping plate 301 rotates, the outer shielding plate 201 will continue to move. A second torsion spring 304 is installed on one side of the clamping plate 301 so that it will reset after the clamping plate 301 rotates, thereby achieving the purpose of constraining the outer shielding plate 201. After the outer shielding plate 201 has moved, the main body 1 can be used. The inner shielding plate 101 and the outer shielding shell 2 are respectively installed on the surface of the main body 1, so that the main body 1 can be fully protected by the inner shielding plate 101 and the outer shielding shell 2. The two outer shielding plates 201 are set on both sides of the outer shielding shell 2, so that the sides can be further protected.
