Electric connector shielding structure and producing method

Abstract

The invention discloses an electric connector shielding structure. The electric connector comprises a contact element, wherein the contact element comprises a signal contact element and an earthing contact element; multiple extension parts are arranged on the earthing contact element; a plastic matrix is arranged outside the contact element; an electroplated layer is arranged on the external surface of the plastic matrix; openings matched with the extension parts arranged on the earthing contact element are arranged on the plastic matrix; the extension direction of the extension parts arranged on the earthing contact element is the thickness direction of the earthing contact element; the electroplated layer is electrically connected with the extension parts arranged on the earthing contact element; and the extension parts arranged on the earthing contact element extend out of the external surface of the plastic matrix. The electric connector shielding structure is produced by injection molding and electroplating processes. By adopting the electric connector shielding structure, the multipoint connection between the earthing contact element and the electroplated layer of the electric connector is realized, thus the shielding is sufficient, and the crosstalk among signal wires in the electric connector is low; and the plastic matrix is not limited by the material, thus the cost and connector weight are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of electric connector structure and manufacture, and in particular relates to a shielding structure and a manufacturing method of an electric connector. Background technique [0002] In the field of communication, there are more and more applications of communication equipment for signal transmission, especially electrical connectors with high transmission speed. In order to meet the high transmission rate, the crosstalk requirements of the electrical connectors in the transmission link should be as small as possible, and the electrical connectors with low crosstalk characteristics play an important role in high-speed signal transmission. In the field of high-speed connectors, there are two main ways to achieve low crosstalk: (1) The signal lines are close to each other to form strong coupling, which in turn has strong anti-interference; (2) Make the ground wire and shield of the contact component fully con...

Problems solved by technology

The disadvantages of this plastic shielding cover are: (1) There are few conductive plastics available in the market, and they are expensive, resulting in increased costs; (2) Due to the internal stress in the injection molding process, the existence of internal stress It may deform or even crack the injection molded parts during use, which not only shortens the service life of the cover plate, but also seriously affects the shielding effect
