Description

Stackable Electrical Connectors

technical field

The utility model relates to a stacked electrical connector, in particular to a transmission protocol conforming to USB (Universal Serial Bus) 2.0 and 3.0, the terminals of which are respectively arranged on different tongues, and then the tongues are assembled on the insulating body stackable electrical connectors.

Background technique

Nowadays, with the rapid development of electronic technology, the form of computer has developed from a desktop computer to a small and easy-to-carry notebook computer, which is ubiquitous in every corner of society. When users want to transmit data, signal or communicate with When other peripheral devices are connected, the so-called peripheral device interface is required. At present, the USB (Universal Serial Bus) interface is generally the mainstream, while the existing connector has an insulating body, and a terminal group is pierced inside the insulating body. One side of the terminal group is A plurality of contact ends exposed at the bottom of the insulating base body, the other side is a plurality of welding ends bent and extended to the outer body of the insulating base body, and a shielding shell is covered on the outer body of the insulating base body, and the USB2.0 transmission protocol is formed through the above structure The connector is installed on the preset electronic device, and the plurality of soldering ends of the connector are welded to the circuit contacts on the circuit board provided in the preset electronic device.

The above-mentioned existing connectors still have many deficiencies in operation and use. For example, the connector is in the form of USB2.0 transmission protocol. In terms of its data transmission speed and stability of power supply, it is only suitable for low-power driving and transmission Peripheral devices with low speed requirements (card readers, printers, flash drives, Internet phones or network cameras, etc.), for external high-storage hard disks, DVD recorders, players and Blu-ray recorders, etc., other The transmission speed is still insufficient, causing inconvenience to users in operation and use, and at the same time, the functions of the above-mentioned electronic devices cannot be fully utilized.

Another example is that the connector can only be plugged into a single external connector, but cannot be plugged into two external connectors at the same time. Therefore, users usually have to purchase and prepare additional hubs, which not only causes inconvenience in use, but also causes problems in use. burden on purchasers.

Furthermore, electronic equipment uses more than one connector in order to provide plugging, so two parallel or spaced connectors need to be installed on the circuit board of the electronic equipment to provide corresponding connections for multiple external peripheral devices at the same time.
