[0002] High-speed electrical connectors are used to support high-performance applications. Signal shielding is the key to the entire design. In the connectors at both ends, the main design is the impedance matching of the entire link and the shielding design during signal transmission; impedance matching is the most important parameter in signal transmission. If the impedance does not match, serious signal crosstalk will occur during high-speed signal transmission, and the signal transmission will be unstable and the quality will be reduced. At the same time, the shielding design of the entire link, if the shielding is incomplete in the link, during the signal transmission process, the signal attenuation and outward radiation will be greatly increased, resulting in a decrease in signal transmission quality.

[0003] In order to ensure stable signal transmission, a shielding structure is provided in the connectors in the prior art. However, in actual use, it is found that the connectors in the prior art are prone to have contact gaps at the plug-in position, which easily reduces the shielding effect. Summary of the invention

[0031] The disclosure below provides many different embodiments or examples to implement different structures of the embodiments of the present invention. In order to simplify the disclosure of the embodiments of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present invention.

[0032] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] See also Figure 1-Figure 3 This embodiment discloses a shielding component structure, including a female needle component 101 and a male needle component 103, wherein the female needle component 101 is used to be installed in a female end body 102, and the male needle component 103 is used to be installed in a male end body 104.

[0034] Among them, the female needle assembly 101 includes a metal cylinder 105 and a first shielding layer 106 arranged on the outside of the metal cylinder 105, and the male needle assembly 103 includes a metal needle 107 and a contact head 108. The metal cylinder 105 is fixedly installed in the female end body 102, the metal needle 107 is fixedly installed in the male end body 104, and the contact head 108 is fixedly installed at the end of the metal needle 107. After the male end body 104 is plugged into the female end body 102, the contact head 108 extends into the metal cylinder 105 and contacts the inner wall of the metal cylinder 105 to realize signal transmission.

[0035] A second shielding layer 109 is arranged on the outside of the metal needle 107, and an arc portion 110 inclined toward the metal needle 107 is provided on the first shielding layer 106. After the male end body 104 and the female end body 102 are plugged into each other, the arc portion 110 is sleeved on the second shielding layer 109 and is in close contact with the second shielding layer 109.

[0036] In actual use, this embodiment realizes signal transmission by plugging the provided female pin assembly 101 and the male pin assembly 103 together, and improves the shielding effect by providing the first shielding layer 106 and the second shielding layer 109 .

[0037] In the present application, since the first shielding layer 106 is provided with an arc portion 110 inclined toward the metal needle 107 , after the male end body 104 and the female end body 102 are plugged into each other, the arc portion 110 is sleeved on the second shielding layer 109 and is in close contact with the second shielding layer 109 .

[0038] In this way, the first shielding layer 106 can cover the first shielding layer 106 to form a stacked structure at the contact position, which can effectively improve the shielding effect at the contact position of the connector.

[0039] Furthermore, the metal cylinder 105 includes a cylinder body 111 and a transfer end 112 . The cylinder body 111 and the transfer end 112 are an integrated structure. The first shielding layer 106 is located outside the cylinder body 111 and the transfer end 112 . In actual use, the metal cylinder 105 is fixedly mounted on the female end body 102 .

[0040] In this embodiment, a high-speed connector is also disclosed, including a female end body 102 and a male end body 104, and also includes a shielding component structure as described above, in which the female pin component 101 is fixedly arranged on the female end body 102, and the male pin component 103 is fixedly arranged on the male end body 104.

[0041] The male end body 104 and the female end body 102 are detachably connected via a connecting assembly 113 .

[0042] Among them, the connecting component 113 includes a connecting column 114, which is fixedly set on the female end body 102, and a through hole 115 is set on the male end body 104. A limiting portion 116 is set at the end position of the through hole 115. The connecting column 114 is made of elastic material, and a plurality of locking protrusions 117 are set on the connecting column 114 near the limiting portion 116.

[0043] In actual use, the male end body 104 and the female end body 102 are connected by the provided connection assembly 113, thereby fixing the connector and preventing it from being disengaged.

[0044] When in use, the connecting column 114 is passed through the through hole 115 , and the locking protrusion 117 cooperates with the limiting portion 116 to achieve locking and fixing of the male end body 104 and the female end body 102 .

[0045] In the prior art, signal transmission is generally achieved by contact between a male pin and a female pin. However, in the prior art, contact is generally achieved by a protrusion on the male pin or the female pin, and close contact is achieved by the preload or elastic force of the protrusion itself. However, in actual use, it is found that the contact part is prone to loosening due to close contact with elastic force, resulting in unstable signal transmission.

[0046] In some preferred implementation cases, the contact head 108 includes an end 118 and a plurality of bending portions 119, a connecting groove is provided at the lower end of the end 118, and the connecting groove is used for fixed connection with the metal needle 107, and the plurality of bending portions 119 are provided at the upper end of the end 118, and the upper ends of the bending portions 119 are close to each other and gathered together.

[0047] When in use, the contact head extends into the interior of the cylinder 111, so that the upper end of the bending portion 119 contacts the bottom of the cylinder 111. During the continuous movement of the male end body 104 and the female end body 102, the bending portion 119 will bend so that the bending portion 119 is in close contact with the inner wall of the cylinder 111, thereby improving the effect of close contact.

[0048] The bent portion 119 contacts the upper end of the cylinder 111 , and the male end body 104 and the female end body 102 are fixed together under the action of the connecting assembly 113 , thereby ensuring that the cylinder 111 and the contact head can be in close contact.

[0049] Furthermore, in actual use, there are multiple locking protrusions 117 on the connecting column 114.

[0050] In this embodiment, the bending portion 119 is an arc-shaped structure, so that when the bending portion 119 is subjected to force, the contact area between the bending portion 119 and the cylinder 111 can be deformed. While ensuring sufficient preload force, the bending portion 119 has a larger contact area with the cylinder 111 after deformation, further improving the model transmission performance.

[0051] At the same time, the tops of the bent portions 119 converge and contact with the cylinder 111, effectively increasing the contact area.

[0052] The locking protrusion 117 is provided with a first guiding inclined surface 120 .

[0053] Furthermore, a clearance groove 121 is provided on the side of the male end body 104 , and an extension portion 122 is provided on the female end body 102 , and the extension portion 122 matches the clearance groove 121 .

[0054] An elastic pad 123 is disposed in the recess 121 .

[0055] The elastic pad 123 is a rubber or silicone pad.

[0056] In the present application, the elastic pad 123 is provided to cooperate with the connecting component 113 .

[0057] The male end body 104 and the female end body 102 are more firmly connected, and under the action of the elastic force of the elastic pad 123, the locking effect of the limiting portion 116 and the locking protrusion 117 is better.

[0058] Furthermore, a first easing groove 121 is provided on the male end body 104 to achieve easing of the metal tube 105 .

[0059] Furthermore, the present invention also discloses a shielding method, which mainly realizes the shielding of the connector through the shielding component structure described above.

[0060] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
