Description

Connector construction

This creation is about a connector that provides electrical connection and signal communication between different devices or devices, especially a USB electrical connector.

The electrical connector is an electronic component that is widely used in various electronic products. The electrical connection of the electrical connector in the device or device helps the signal transmission and communication between each other.

What this writing is about is a USB (Universal Serial Bus)-universal serial bus connector. The connector mainly includes an insulating carrier, a plurality of terminals mounted on the insulating carrier, and a plurality of terminals. The connected circuit board is connected to the interface line connected to the device through the plural terminals to complete the data transmission.

Due to the frequent insertion and removal of USB between devices, it is necessary to strengthen the internal connection structure to maintain the stability of data transmission. For example, the USB connector disclosed in the Patent Announcement No. M444655 of the Republic of China is a pin The connection relationship between the plural terminals and the internal circuit board is strengthened, and the two fixed terminals arranged on both sides of the insulating carrier are used to make the connection relationship between the mechanisms more stable, and the problem of damage to the mechanism caused by frequent insertion and removal is improved. However, the fixed terminal designed by this patent is placed on the two long sides of the insulating carrier, and the installation path is obviously too long, which makes the quality of assembly easily hindered; although it also mentions that the use of Insert Molding technology The manufacturing process is simplified, but the positioning of these fixed terminals in the mold must still be considered, whether they can withstand the impact of the insulating material to produce deformation, misalignment, etc., and the manufacturing cost is relatively high.

This creation provides a "connector structure" that is more novel than the prior art. The structure of the specific implementation includes an insulating carrier with a plurality of limiting slots and at least one fixing hole, the fixing hole penetrates the insulating carrier from top to bottom A plurality of terminals, which are installed in the limit slot separately; a circuit board, which is electrically connected to the plurality of terminals; and, at least one fixed terminal, which has a compatible with the fixed hole and can be fastened to The fixed end in the fixing hole, and one end connected to the fixed end, the other end penetrating through the fixing hole is electrically connected to the circuit board, so as to strengthen the connection between the overall connector and the circuit board Helping the connector to complete the ground to suppress the interference of noise is the main purpose of this creation.

As one of the preferred solutions, the connection end of the fixed terminal The end is further bent toward the outside of the connector to electrically connect the connection board to the circuit board to increase the contact area and strengthen the connection relationship.

As one of the preferred solutions, one side of the fixing hole passes through an assembly hole with a diameter smaller than the fixing hole toward the outside of the insulating carrier, so that the connecting plate falls in the assembly hole to facilitate the installation of the fixed terminal.

As for the other detailed structures of this creation, and the excellent effects produced, please refer to the embodiments described later for details.
