Description

Shell grounding structure of electrical connector

The present invention relates to a shell grounding structure of an electrical connector, in particular to a wire-end connector in which the shielding shell has a large buckling plate, which allows a plurality of resisting elastic pieces disposed therein to allocate a larger space. , so each resisting elastic piece can be designed to be relatively wide and thick, and the suspended end forms a resisting surface that is vertically flat against the surface of the metal shell, and the mating board-end and line-end connectors can still maintain their original shape after being plugged and unplugged many times. With a shape and no deformation problem, the contact structure between the metal shell and the shielding shell can be confirmed, so as to achieve the good effect of electromagnetic wave shielding and elimination of the mutual distribution connector.

Press, general connectors are connecting components and accessories used in electronic signals and power supplies. Their main function is to provide connections between various electronic devices or equipment and ensure that signals can be transmitted accurately. Connectors follow the products they are used in. , power and usage environment, various types have been developed, and can be widely used in consumer electronics such as computers, notebook computers, smart phones, or in the fields of household appliances, telecommunications and communication equipment. , and because the current design of electronic products tends to be light, thin, short, and small, the connectors inside various electronic products need to be greatly reduced. In comparison, the connection between thin connectors and ordinary wires or flexible circuit boards And fixation is bound to be more difficult.

Furthermore, as electronic products become increasingly thinner, the The structure of the components on the externally mounted circuit board needs to be more precise and miniaturized, and the overall structural strength also needs to be strengthened. General connectors (such as board-to-board connectors or wire-to-board connectors, etc.) usually use a The male connector and a female connector are mated together, and the signal or power is transmitted to the control circuit through the circuit board to perform the corresponding operating function. However, when the male connector is mated with the female connector, in order to reduce the overall structure Height, most of them are assembled by fitting. First, the body of the male connector is inserted into the fitting space of the female connector, and the protruding buckle of the body is fastened into the buckle groove of the base. The plurality of conductive terminals of the body can be pressed against the corresponding contact terminals on the base to form an electrical connection, thereby realizing an electrical connection between two parallel opposing circuit boards, or a flexible circuit board, a cable and a circuit board.

However, when a plug connector with wires is to be plugged into a socket connector provided on the board end to form a mutual match, it is necessary to rely on the outer metal shells of the two electrical connectors to engage with each other and conduct grounding to eliminate the problem of Electrical connectors generate electromagnetic waves when transmitting electronic signals at high speeds. The conventional contact springs of the metal shell are arranged outside the socket connector. Since the contact springs need to form multiple points of contact, they are designed to be very small and thin. After the electrical connector has been plugged and unplugged for many times, it is easy to cause the tiny contact springs to undergo irrecoverable deformation due to the resistance stress, further causing the problem of poor contact or even inability to contact some or all of the contact springs. This will not form effective electromagnetic wave shielding and Eliminate the effect.

Therefore, how to solve the deficiencies and inconveniences of the above-mentioned customs is an urgent direction for improvement by relevant industry players.
