Description

Female connector, male connector and combination thereof

This creative system provides a female connector, a male connector, and a combination thereof. Especially when the shield case is assembled to the first position, the plural terminals of the terminal group can be soldered, and when the shield case is assembled to the second When in position, the shielding housing completely covers the connection ends of the plurality of terminals to form a good shielding effect, thereby improving the quality and stability of signal transmission.

According to the current rapid development of science and technology, all kinds of electronic devices continue to develop. Among them, various electronic devices are mostly electronic components that are electrically connected to each other, and can be transmitted, calculated or processed by electronic signals through various electronic components. Processing to complete various functions of the electronic device.

In the aforementioned electronic devices, the board-to-board connector technology used to transmit electronic signals between two circuit boards is widely used. Most of the board-to-board connectors' female or male connectors have an insulating base. And a mating portion is provided on the surface of the insulating base (for example, the female connector is a plug slot and the male connector is a tongue plate), and a plurality of transmission terminals penetrating to the bottom of the insulating base are penetrated in the mating portion. In practice, the plurality of transmission terminals at the bottom of the insulating base body are welded to the circuit board, so that the circuit layout on the circuit board is electrically connected to each transmission terminal, and correspondingly installed on the two circuit boards in this way. The type of board-to-board connector is to electrically connect the circuit layouts of the two circuit boards to each other through the mutual plugging of the two board-to-board connectors. For electronic devices to transmit electronic signals during use.

However, with the increase in the transmission speed of electronic signals in various electronic devices today, the high-frequency transmission impedance of each transmission terminal in the board-to-board connector when transmitting electronic signals also increases, so that when transmitting electronic signals Can produce electromagnetic wave interference (EMI) and crosstalk interference, resulting in unstable and abnormal transmission quality of electronic signals, thereby preventing normal function execution.

Therefore, how to reduce the high-frequency transmission impedance, electromagnetic waves, and crosstalk interference of board-to-board connectors in transmitting electronic signals is the direction that related manufacturers in this industry are eager to study and improve.

Therefore, in view of the above-mentioned problems and deficiencies, the creators collected relevant information, evaluated and considered from various parties, and based on years of experience accumulated in this industry, through continuous trial and modification, they began to design such female connector, New types of male connectors and combinations are born.

The main purpose of this creation is that the base surface of the base body of the female connector and the male connector is provided with a first positioning portion and a second positioning portion, respectively, and a docking portion is provided above the base. A plurality of terminals of a terminal group are positioned on the base body, and one end of each terminal is formed with a contact end extending into the docking portion, and the other end is formed with a connection end extending out of the base body, and the base body is inserted into the shielding housing. In the housing space, a first fixing portion and a second fixing portion are provided on the inner wall surface of the containing space. When the shielding case is located at the first position, the first fixing portion of the shielding case is the first positioning portion of the housing. On the positioning portion, and when the shielding case is moved to the second position, the first fixing portion and the second fixing portion are respectively positioned on the second positioning portion and the first positioning portion, and at the same time, the shielding case is covered The external terminals of the plurality of terminals are held to form a good shielding effect, thereby effectively suppressing or filtering electromagnetic wave and crosstalk interference, thereby achieving the purpose of improving the stability of signal transmission quality.

The secondary purpose of this creation is that when the shielding shell of the female connector and the male connector is assembled to the first position at the base, the terminal group is elastically supported by the elastic part of the two elastic pieces to support the capacitor. Place the enclosure around the opening above the space to avoid the shield housing from being assembled directly to the second position, thereby facilitating the soldering operation of the connecting ends of the multiple terminals, thereby achieving the purpose of facilitating assembly operations.

Another purpose of this creation is that when the female connector is mated with the male connector, the contact board of the female connector shield shell is in contact with the multiple contact pieces of the male connector shield shell to form a ground. The loop can increase the path and density of ground conduction to reliably export the electromagnetic waves and crosstalk interference generated during signal transmission to the outside, thereby achieving the purpose of making the overall signal transmission quality more stable and reliable.

Another purpose of this creation is that when the female connector is mated with the male connector, the elastic part of the two elastic pieces is in contact with the shield shell to form a ground loop, and then the signal can be transmitted through the welding part of the two elastic pieces. The generated electromagnetic waves and crosstalk interference are led out to improve the overall grounding purpose.
