Description

Connector for high speed and high frequency signal transmission}

The present invention is a high-speed, high-frequency signal transmission connector, and more specifically, the size in the width direction of the connector mating state is reduced while effectively blocking electromagnetic interference (EMI) through a double shielding structure according to surface contact fitting between shield wall members when mating between connectors. It's about a further reduced connector technology.

In order to electrically connect circuit boards, a board to board connector (BtB connector) is mainly used. When coupling between connectors, electrical connection is made through matching between pins, so that electrical signals can be transmitted between boards.

Recently, a high-speed signal transmission connector having a high data rate of 28 Gbps, 56 Gbps, or 112 Gbps or more is required due to the demand for scalable computing.

In addition, as 5G and 6G mobile telecommunication frequency bands of 28 GHz and 43 GHz bands and higher mmWave bands are put into practical use, the importance of connectors suitable for signal transmission in these high frequency bands is emerging.

In the case of such a high-speed, high-frequency signal transmission connector, it is required to accurately transmit high-frequency electrical signals without loss. Therefore, when mating between connectors, it is necessary to stably satisfy high-speed signal transmission while satisfying high-frequency characteristics through matched terminals.

One factor that hinders signal transmission according to such high-speed and high-frequency characteristics is so-called electromagnetic interference noise (EMI), such as an electromagnetic noise signal generated from a terminal of a connector.

When transmitting high-frequency signals between connectors, various electromagnetic wave shield members such as shield walls or shield cells are applied to connectors in order to eliminate electromagnetic interference (EMI). For example, a shield wall or a shield cell corresponding to each other is used for a plug connector and a receptacle connector, and electromagnetic wave shielding between the inside and outside of the connector is achieved through an electromagnetic wave shield member when the connectors are mated.

Furthermore, when the connectors are mated, leakage and inflow of electromagnetic waves occur at the portion where the shield members are in contact. To solve this problem, a technology for realizing double shielding by contacting and fitting surfaces of the shield members has been proposed.

However, there is a problem in that the overall size of the connector increases in order to implement such a double shielding structure in a situation in which slimness and miniaturization of connectors are required due to miniaturization or high functionality of electronic systems and mobile communication terminals and high density and high integration of internal electronic components. . In addition, due to the double contact structure between the shield members in a mated state between the connectors, there is a problem in that the space occupied by the mated connectors on the board increases accordingly.

Furthermore, a connector having a hermaphroditic structure has been proposed in order to promote manufacturing efficiency of the connector and to solve the inconvenience caused by the distinction between the plug connector and the receptacle connector.

A connector having such a hermaphroditic structure has an advantage in that identical connectors can be mated regardless of connector types because one connector has a plug and a receptacle function.

However, in the case of a connector having a hermaphroditic structure, there is a problem in that mating robustness and reliability between connectors are deteriorated due to structural limitations for realizing the hermaphroditic body.
