High frequency signal connector having structure for preventing external electromagnetic interference

Abstract

The invention provides a high frequency signal connector having a structure for preventing external electromagnetic interference. The high frequency signal connector is arranged on the circuit, and is connected to a conductive casing. The connector comprises a dielectric body, a plurality of conductive terminals, a conductive casing, and a piece of metal spring. The conductive terminal is buried in the dielectric body, and welded to the circuit board. The conductive casing encapsulates the outside of the dielectric body, and the metal spring is disposed at the conductive housing. The metal spring includes a flat portion and a tongue portion. The flat portion is composed of a base and at least one tongue root extending from the base. The tongue root extends out, forming the tongue portion. The tongue portion is far away from the conductive casing, forming a spring stress bearing part to be connected to the conductive casing under stress. By adopting the scheme, the structure of the invention is applicable to connectors with different specifications.

Description

technical field [0001] An anti-crosstalk connector, especially a high-frequency signal connector with a structure for preventing external electromagnetic interference for high-frequency signals. Background technique [0002] A major trend in the electronics industry in recent years is the miniaturization of electronic products. For easy portability, such as laptops, tablet computers, and smart phones, the internal space is often reduced due to the narrowing of the volume, so that the internal electronic components are close to each other; thus deriving electromagnetic Interference EMI (ElectroMagnetic Interference) problem. For example, two adjacent USB connectors, one of which is plugged into the signal transceiver of the wireless mouse, and the other is connected to an external hard disk. When the external hard disk transmits a large amount of information through the USB connector, the high-frequency electrical signal is serially connected to the adjacent USB connector th...

AI Technical Summary

Problems solved by technology

[0007] Its disadvantages are: the size, length, width, and bending angle of the covering structure are completely customized according to the size of the specific connector, and there is no flexibility in the application, and it cannot be temporarily socketed to other specifications of the connector

Once the demand decreases, it will cause waste and increase the cost unnecessary; on the contrary, it will be difficult to respond immediately when additional production is temporarily required, which will cause delays

[0008] Furthermore, fitting the cladding structure to the outside of the connector requires better precision. A slight deviation during the threading process will cause the structure of the cladding structure to be distorted, resulting in a needless reduction in product yield and increased processing costs.

In particular, this design needs to be covered by multiple sides, such as a continuous three-to-four-sided bending structure to firmly clamp the connector, and the actual contact with the housing of the electronic product for conduction usually only needs one side, which means that it is unnecessary waste of materials, making this scheme synchronously bring many negative effects

[0009] The various improved versions of the above connectors have problems such as high cost, difficulty in assembling into electronic products, low flexibility due to the specialization of each component, low combined manufacturing yield, and waste of resources.
