Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and in particular relates to a display port connector. Background Art

[0002] Connector, or CONNECTOR. It is also called connector, plug and socket in China. It generally refers to an electrical connector. It is a device that connects two active devices to transmit current or signals. Connectors are indispensable components in electronic devices. If you observe along the path where the current flows, you will always find one or more connectors. The form and structure of connectors are ever-changing. There are various forms of connectors depending on the application object, frequency, power, application environment, etc.

[0003] DisplayPort, also known as the display port connector, is the first display communication port that relies on packetized data transmission technology, which can be found in technologies such as Ethernet, USB and PCI Express. It can be used for both internal and external display connections. Unlike past standards that require fixed transmission of timer signals in the differential pair at each output, the DisplayPort protocol is based on small data packets called micro packets. This micro packet can embed the timer signal in the data stream, which has the advantage of achieving higher resolution with only a small number of pins. The use of data packets also allows DisplayPort to be scalable, which means that additional functionality can be added over time without significant changes to the physical communication port itself.

The spacer 400 is clamped between the upper terminal assembly 500 and the lower terminal assembly 600 to form a connected whole. Among them, the spacer 400 is used to isolate and shield the signals of the upper terminal 501 and the lower terminal 601 which are distributed vertically, so as to avoid crosstalk between the upper terminal 501 and the lower terminal 601. The rubber core 300 is injection molded on the connection as a whole, and the upper terminal 501 and the lower terminal 601 have exposed contact surfaces. The tail ends of the upper terminal 501 and the lower terminal 601 extend from the bottom of one end of the rubber core 300 and are on the same plane, so that the display port connector can be soldered on the circuit board by means of a patch. The rubber core 300 is arranged in the rubber shell 200, and the metal shell 100 is wrapped on the outside of the rubber shell 200. The display port connector of this embodiment is provided with an isolation sheet 400 between the upper terminal assembly 500 and the lower terminal assembly 600, and the isolation sheet 400 isolates the signals of the upper terminal 501 and the lower terminal 601 to avoid signal crosstalk between the upper terminal 501 and the lower terminal 601; ensure that the signal can be transmitted normally.
