Description

Anti-interference structure of connector socket interface

technical field

The utility model relates to an anti-interference structure of a connector socket interface, in particular to a design for isolating signal interference by arranging metal sheets.

Background technique

Today's electronic products are increasingly diversified in terms of functions and multimedia applications, so there are various connectors to transmit the required data or multimedia, and plug-in connectors such as HDMI and DisplayPort are required for higher and higher transmission speeds. At the same time, the upper and lower rows of terminals will generate signal interference, but the socket interface of the current plug-in connector does not have a structure that is easy to implement and effectively prevents signal interference.

Utility model content

The main purpose of the utility model is to provide an anti-interference structure of the connector socket interface, which is easy to implement and effectively prevents signal interference.

In order to achieve the above-mentioned effects, the anti-interference structure of the connector socket interface provided by the utility model is that an upper row of terminals is provided on the upper surface of a tongue plate, and a lower row of terminals is provided on the lower surface of the tongue plate. The rear end is electrically connected to the upper row of metal terminals relative to the upper row of terminals, and the rear end of the tongue plate is electrically connected to the lower row of metal terminals relative to the lower row of terminals. The upper row of metal terminals and the lower row of metal terminals are positioned together. On a base, a metal sheet is arranged in the middle of the base to isolate signal interference between the upper row of metal terminals and the lower row of metal terminals.

In addition, the tongue plate is made of a multi-layer circuit board, the upper row of terminals on the upper surface of the tongue plate is the upper row of line terminals, the lower row of terminals on the lower surface of the tongue plate is the lower row of line terminals, and the tongue plate’s A ground layer is provided in the middle to isolate the signal interference between the upper row of line terminals and the lower row of line terminals.

Detailed ways

First, please refer to Figs. 1 to 3, the first embodiment of the present invention is to make a tongue plate 10 of DisplayPort with a multi-layer circuit board. The lower surface is provided with a lower row of line terminals 22, and the middle of the tongue plate 10 is provided with a grounding layer 23 to isolate the signal interference between the upper row of line terminals 21 and the lower row of line terminals 22. The rear end of the tongue plate 10 is opposite to the upper row of line terminals. 21 is electrically connected with an upper row of metal terminals 31, and the rear end of the tongue plate 10 is electrically connected with a lower row of metal terminals 32 relative to the lower row of line terminals 22, and the upper row of metal terminals 31 and the lower row of metal terminals 32 are positioned together On a base 30 , a metal sheet 33 is disposed in the middle of the base 30 to isolate signal interference between the upper row of metal terminals 31 and the lower row of metal terminals 32 .

Next, please refer to FIGS. 4 to 6. In the second embodiment of the present invention, a tongue plate 40 for HDMI is made of a multilayer circuit board. The upper surface of the tongue plate 40 is provided with an upper row of line terminals 51. The lower surface is provided with a lower row of line terminals 52, and the middle of the tongue plate 40 is provided with a grounding layer 53 to isolate the signal interference between the upper row of line terminals 51 and the lower row of line terminals 52. The rear end of the tongue plate 40 is opposite to the upper row of line terminals. 51 is electrically connected with an upper row of metal terminals 61, and the rear end of the tongue plate 40 is electrically connected with a lower row of metal terminals 62 relative to the lower row of line terminals 52, and the upper row of metal terminals 61 and the lower row of metal terminals 62 are positioned together On a base 60 , a metal sheet 63 is disposed in the middle of the base 60 to isolate signal interference between the upper row of metal terminals 61 and the lower row of metal terminals 62 .

Based on such a structure, the utility model is provided with a grounding layer 23/53 in the middle of the tongue plate 10/40 to isolate the signal interference between the upper row of line terminals 21/51 and the lower row of line terminals 22/52, and locates the upper row of metal There is a metal sheet 33/63 between the base 30/60 of the terminal 31/61 and the lower row of metal terminals 32/62, and the metal sheet 33/63 is used to isolate the upper row of metal terminals 31/61 and the lower row of metal terminals 32/62 signal interference; therefore, the utility model sets the grounding layer 23/53 in the middle of the tongue plate 10/40, and sets the metal sheet 33/63 in the middle of the base 30/60 for positioning the metal terminals.
