[0002] Connectors, also known as plugs, sockets, and connectors, are used for the transmission of current and signals between two active devices. When designing high-performance electronic devices such as laptops, design engineers often face the challenge of electromagnetic interference (EMI). When these devices use connectors for signal transmission, the electromagnetic shielding performance of the connector largely determines the signal transmission quality; therefore, designing a connector with good shielding performance is crucial.

[0003] Existing connectors typically use a metal shell as a shield to shield against electromagnetic interference. However, there is often a gap between the metal shell and the wire, which still poses a risk of signal interference / leakage during high-speed signal transmission. Utility Model Content

[0029] refer to Figures 1-5As shown, this embodiment proposes a socket and connector, which can be used for EDP signal transmission and charging of electronic devices including but not limited to laptops. The connector includes a plug 20 and a socket 10 in this embodiment. Both the plug 20 and the socket 10 include a plurality of conductive contacts or terminals disposed therein. When the plug 20 and the socket 10 are mated, the conductive contacts or terminals are electrically connected to each other. The socket 10 includes a shielding shell 11, a substrate 12, wires 13, and conductive foam 14. The substrate 12 is located within the shielding space formed inside the shielding shell 11 and can be a printed circuit board or a flexible circuit board. The shielding shell 11 can be made of stainless steel or copper alloy and other metal materials. The first ends of the plurality of wires 13 are electrically connected to the substrate 12 by means including but not limited to welding and crimping, and the second ends of the wires 13 extend out of the shielding shell 11. The conductive foam 14 wraps around the wires 13 and abuts against the shielding shell 11.

[0030] The conductive fabric foam 14 in the connector can fill the gap between the shielding shell 11 and the wire 13, absorb and reflect electromagnetic waves, especially electromagnetic waves in the range of 3MHz-10GHz, thereby effectively reducing signal interference / leakage, while also improving the compatibility of the shielding shell 11 and achieving shock absorption.

[0031] Specifically, the conductive fabric foam 14 is composed of conductive fabric wrapped around high-elasticity PU foam. The conductive fabric and the high-elasticity PU foam are bonded together using hot melt adhesive. The conductive fabric is made by coating the surface of a fiber fabric, such as polyester fiber fabric, with metals such as copper and nickel. The combination of copper and nickel gives the conductive fabric excellent conductivity, as well as anti-oxidation and anti-corrosion properties. To fix the conductive fabric foam 14 inside the shielding shell 11, the conductive fabric foam 14 is bonded to the wire 13 or other internal structures of the shielding shell 11, such as the substrate 12. To reduce the contact resistance between the foam and the conductive fabric, a highly viscous conductive film, such as a conductive film formed by an acrylic adhesive, is adhered to the side facing away from the foam. More specifically, to reduce the possibility of oxidation, the surface of the conductive fabric has been treated with an anti-oxidation agent.

[0032] The conductive fabric foam 14 is bonded to the wire 13 using a conductive adhesive film. This not only reduces the contact resistance between the foam and the conductive fabric, resulting in better electromagnetic shielding, but also makes it easy to fix and bond during use. Simply peel off the release paper attached to the adhesive surface of the conductive adhesive film.

[0033] The conductive foam 14 is also connected to an insulating adhesive layer 15. The insulating adhesive layer 15 can prevent the conductive foam 14 from short-circuiting with other external devices, which would cause the electromagnetic signal shielding to fail. Specifically, the insulating adhesive layer 15 can be made of acetate cloth insulating tape, which has good shape retention and is easy to operate.

[0034] refer to Figure 2As shown, in order to achieve effective contact between the conductive fabric foam 14 and the shielding shell 11, the shielding shell 11 is provided with a groove 112 recessed towards the conductive fabric foam 14 at the position corresponding to the position of the conductive fabric foam 14. The groove 112 can effectively pre-compress the conductive fabric foam 14, causing the conductive fabric foam 14 to shrink under force and thus achieve effective contact with the shielding shell 11. In this embodiment, the groove depth of the groove 112 is between 0.1-0.16 mm.

[0035] refer to Figure 3 As shown, to maintain the connection between the plug 20 and the socket 10, the plug 20 is provided with a plug portion 21, and the socket 10 is provided with a socket located inside the shielding shell 11. The plug portion 21 can be inserted into the socket, and the terminals or conductive contacts on the socket 10 are at least partially located inside the socket, so that an electrical connection between the plug 20 and the socket 10 can be achieved after the plug portion 21 is inserted into the socket. In this embodiment, the socket 10 supports reversible insertion of the plug 20. Specifically, the substrate 12 is provided with double-sided gold fingers, which pass through the socket, and two sets of wires 13 are symmetrically arranged on opposite sides of the substrate 12. In addition, to facilitate the layout of the wires 13, the socket 10 also includes a central support plate 18, which is disposed between the two layers of wires 13 and is fixedly connected to the PCB board. Specifically, the central support plate 18 is made of stainless steel.

[0036] continue Figure 2 and Figure 5 As shown, the shielding shell 11 includes a first shell 114 and a second shell 115. The first shell 114 and the second shell 115 together form the shielding space. In order to make the shielding shell 11 have better shielding performance, the first shell 114 and the second shell 115 are welded together by multiple laser welding points.

[0037] Specifically, mounting holes 113 are provided on the first housing 114 and the second housing 115, and the socket 10 can be fixed in a certain installation position by fasteners passing through the mounting holes 113. Furthermore, the laser welding points for connecting the first housing 114 and the second housing 115 include a plurality of first welding points arranged around the mounting holes 113 and a plurality of second welding points arranged on the sides of the first housing 114 and the second housing 115.

[0038] In this embodiment, in order to achieve quick connection between plug 20 and socket 10, socket 10 is provided with a first magnetic adsorption member 17 and plug 20 is provided with a second magnetic adsorption member (not shown in the figure). Plug 20 and socket 10 are magnetically connected through the first magnetic adsorption member 17 and the second magnetic adsorption member, which can reduce the problems of difficult docking and inconvenient plugging and unplugging of plug 20 and socket 10.

[0039] Specifically, the first adsorption element 17 is a ferromagnetic metal, and the second adsorption element is a magnet. The first adsorption element 17 is located inside the shielding shell 11 and at the end away from the wire 13. The first adsorption element 17 and the shielding shell 11 are welded together by multiple laser welding points to further improve the performance of electromagnetic interference resistance.

[0040] In this embodiment, wire 13 is a coaxial cable. Specifically, the coaxial cable includes a central conductor, an insulation layer, a shielding layer, and a sheath arranged from the inside out. The shielding layer is made of tin-plated copper alloy wire, which is braided into a mesh structure, thus forming the shielding layer. This increases the shielding effect, blocks external electromagnetic interference, and improves the anti-interference capability of wire 13. Compared to galvanized copper wire, tin-plated copper alloy wire has better mechanical properties and corrosion resistance.

[0041] refer to Figure 3 and Figure 4 As shown, the socket 10 also includes grounding rods 16. The two grounding rods 16 are located on the side of the coaxial line facing the substrate 12 and the side facing away from the substrate 12, respectively. The shielding layer of the coaxial line is connected by tinning during the manufacturing process (removing the sheath of the part of the coaxial line corresponding to the grounding rod 16) to prevent the shielding layer from exploding and to further improve the shielding effect.

[0042] Specifically, the grounding rod 16 is made of phosphor bronze with an outer nickel and tin plating layer to reduce welding difficulty and avoid problems such as brittle breakage of the grounding rod 16 due to differences in plating.

[0043] Continue to refer to Figure 3 As shown, the grounding rod 16 is soldered to the shielding shell 11. This arrangement allows leakage current to flow into the ground through the grounding rod 16, protecting operators from electric shock while ensuring the shielding effect.

[0044] Specifically, the shielding shell 11 has a window 111 at the position corresponding to the grounding rod 16. The grounding rod 16 can be fixed by adding tin through the window 111, or the tin layer reserved on the grounding rod 16 can be melted and connected to the shielding shell 11. This allows static charge to be released quickly, effectively preventing static accumulation and discharge, protecting the circuit from damage caused by static electricity, improving the stable operation of the circuit in complex electromagnetic environments, and helping to reduce circuit problems caused by poor contact or signal interference. At the same time, it can also enhance conductivity, reduce resistance, and ensure the efficiency of current transmission. Moreover, the tin layer (including the tin layer reserved on the grounding rod 16 or the tin layer formed by melting the tin added through the window 111) has a certain anti-oxidation effect, which can extend the service life of the connector and reduce the problem of poor contact caused by oxidation.

[0045] For example, eight windows 111 are spaced apart along the length of the grounding rod 16. The shape and size of the windows 111 are not specifically limited in this embodiment, as long as they can achieve the soldering connection between the shielding shell 11 and the grounding rod 16.

[0046] In summary, the above connectors achieve effective grounding from the inside out, thus improving their EMI performance.

[0047] When welding the grounding rod 16 to the shielding layer, the grounding plate can be separated into individual grounding rods along the indentation and placed in the material tray. Use tweezers to pick up a grounding rod (without ground claws) and place it into the carrier groove 112. Before placing it, confirm that there are no foreign objects in the carrier. Take a cable and place the shielding layer of the coaxial line flush with the first grounding plate and place it in the corresponding pin position. Take another grounding rod (with ground claws) and place it flush with the shielding layer. Flip the cover plate and press it on the second grounding plate. After fixing the carrier, place it in the automatic soldering slide for automatic soldering.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
