Description
Technical Field
The invention relates to a terminal structure of a Displayport connector, in particular to a terminal structure of a Displayport connector, which can effectively reduce high-frequency signal reflection by properly changing the continuous design of secondary bending of a plurality of first terminals and second terminals at a preset angle and increasing equivalent capacitance between the terminals and adjusting the matching characteristic impedance of the shape change (such as length and width) of the terminals when the first terminals and the second terminals transmit high-frequency signals, thereby greatly improving the integrity of the signals, enabling the whole signal transmission to be more stable and reliable and strengthening the quality of high-speed transmission signals.
Background
The electronic connector is widely used in various communication devices, and as a transmission and connection element of electronic signals, the connector sockets of common standard specifications include RJ-11 (telephone line socket), RJ-45 (network line socket), USB (universal serial bus), IEEE1394 (serial bus), RF (radio frequency) transmission port, Pin-header and Displayport.
Among the above connectors, a display port (Displayport) connector is widely used for image signal transmission, and most of the Displayport connectors are horizontally arranged on a circuit board to be connected and fixed. However, the current electronic products are designed in the direction of light, thin, short and small, and the Displayport connector cannot occupy more than half of the space of the circuit board in the limited space of the circuit board, so that the trend of changing the horizontal Displayport connector into the vertical type is a trend, so that the space of the circuit board can be simplified, and more electronic element layouts can be made on the circuit board.
The terminal seat of the prior Displayport connector socket is fixed by a seat body foot position groove, and the tongue piece and the welding foot are respectively aligned and then assembled, so the assembly difficulty is higher. Secondly, the grounding path from the shell to the front iron shell to the grounding pin is completed by three members, and if the electrical connection between the three members is not good, the grounding operation of the noise cannot be completed. Furthermore, the lower part of the platform of the seat body is made of solid plastic, which consumes more plastic and causes the problem of higher manufacturing cost of the Displayport connector socket.
Furthermore, the terminal set of the conventional Displayport connector has a poor structural design, which cannot achieve a better matching characteristic impedance, and cannot reduce the reflection of high-frequency signals, so that the integrity of signals is greatly compromised, and the signal transmission stability is poor, which needs to be improved by those skilled in the art.
