Abstract

The invention relates to the connector technology field, and discloses a DVI adapter. The adapter comprises a hollow shell, a circuit board arranged in the shell, an interface male head, an interfacefemale head and a signal indicating lamp, wherein a power supply circuit, a signal detection circuit and a protection circuit for preventing an electronic device from being broken down are arranged onthe circuit board; the interface male head is exposed out of one end of the shell, the interface male head is connected with the shell, and fixing screws are arranged on the two sides of the interface male head; the interface female head is exposed out of one end, far away from the interface male head, of the shell, the interface female head is connected with the shell, and the two sides of the interface female head are provided with fixing nuts respectively; and the signal indicating lamp is arranged on an outer side of the shell, the signal indicating lamp is located between the interface male head and the interface female head, and a lower end of the signal indicating lamp is connected with the circuit board. The DVI adapter is compact in structure, stable and reliable in assembling and capable of effectively protecting connected electronic products.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to a DVI adapter. Background technique [0002] Digital Visual Interface (DVI) is an international open interface standard, widely used in PC, DVD, high-definition television (HDTV), high-definition projector and other equipment. DVI is based on TMDS (Transition Minimized Differential Signaling) technology to transmit digital signals. TMDS uses advanced coding algorithms to encode 8-bit data (each primary color signal in R, G, and B) into 10-bit data (including Line and field synchronization information, clock information, data DE, error correction, etc.), after DC balance, the differential signal is used to transmit data. Compared with LVDS and TTL, it has better electromagnetic compatibility performance and can be realized with low-cost special cables. Long-distance, high-quality digital signal transmission. [0003] There are certain defects in the structural design of the D...
