This digital interface has a simple structure, effectively shields the terminals between the upper rubber base and the lower rubber base, and solves the signal interference between the terminals. question.

In order to achieve the above object, the utility model is achieved through the following technical solutions: it includes a front shell, a rear shell, a rubber seat, an upper glue seat and a lower glue seat, the rear shell is fastened to the front shell, and the upper glue seat is embedded in injection molding There are nine terminals, and the lower rubber seat is embedded and injected with ten terminals. After the upper rubber seat, the lower rubber seat and the rubber seat are assembled, they are installed in the accommodation space formed by the front shell and the rear shell. A stainless steel shrapnel is arranged between the rubber seats.

One end of the stainless steel shrapnel is embedded and injected on a plastic spacer.

A square hole is provided on the stainless steel shrapnel, and the square hole is tightly fitted with the distance-shaped protrusion on the lower rubber seat.

The two sides of the stainless steel shrapnel are formed with bent clips, and the two bent clips are closely contacted or buckled with the front shell respectively to conduct and ground.

Both surfaces of the plastic spacer are formed with a plurality of spacers, and the grooves formed by each spacer correspond one-to-one to the connection points at the tails of each terminal.

The utility model is to add a stainless steel shrapnel or iron piece between the upper rubber seat and the lower rubber seat of the digital interface. Conduction and grounding with the front shell, so that the stainless steel shrapnel can effectively shield the signal interference between the terminals of the upper rubber seat and the lower rubber seat. In summary, the utility model has a simple structure and can effectively shield the terminals of the upper rubber seat and the lower rubber seat Interference between signals, to ensure the performance of the digital interface, to ensure its high stability and high transmission speed.

Description of drawings:

Accompanying drawing 1 is the structural representation of the utility model.

Detailed ways:

See accompanying drawing 1 for embodiment, it comprises front shell 1, rear shell 2, rubber base 3, upper rubber base 4 and lower rubber base 5, rear shell 2 is fastened on the front shell 1, and front shell 1 and rear shell 2 form One accommodation space, the upper rubber seat 4 is embedded and injected with nine terminals 6, the lower rubber seat 5 is embedded with ten terminals 14, and there is a stainless steel shrapnel 7 between the upper rubber seat 4 and the lower rubber seat 5. The elastic sheet 7 is located in the middle of the upper rubber seat 4 and the lower rubber seat 5. The stainless steel elastic sheet 7 separates the upper rubber seat 4 and embeds the injection-molded terminal 6 and the lower rubber seat 5 is embedded in the injection-molded terminal 14, effectively shielding the upper rubber seat 4 Signal interference between the nine terminals 6 embedded in injection molding on the upper side and the ten terminals 14 embedded in injection molding on the lower rubber base 5 .

The stainless steel shrapnel 7 is molded on a plastic spacer 8, and one end of the stainless steel shrapnel 7 is injection-molded and embedded in the plastic spacer 8, and a plurality of spacers 9 are formed on both sides of the plastic spacer 8, each spacer The grooves formed by the strips 9 correspond to the tail junctions 13 of the terminals 6 and 14 one by one, and the grooves formed between the spacers 9 are used to accommodate the tail junctions 13 of the terminals 6, and at the same time can achieve a good High voltage resistance and insulation resistance function.

The stainless steel shrapnel 7 is provided with a square hole 10, the square hole 10 is fastened and fixed with the rectangular bump 11 on the lower rubber seat 5, and the upper glue seat 4, the stainless steel shrapnel 7 and the lower rubber seat 5 are assembled on the Together, the stainless steel elastic piece 7 is positioned through the square hole 10 and the rectangular protrusion 11, so that the position of the stainless steel elastic piece 7 is fixed.

After the upper glue seat 4, the stainless steel shrapnel 7 and the lower glue seat 5 are assembled, the contact terminals 6 and 14 at the front ends of the glue upper seat 4 and the lower glue seat 5 are put into the glue seat 3, and then put into the front shell 1 and the rear shell 2. in the formed accommodation space.

There are bending clips 12 on both sides of the stainless steel shrapnel 7, and the two bending clips 12 are respectively fastened and fixedly in contact with the front shell 1 to further fix the stainless steel shrapnel 7 so that it is difficult to come out; or the bending clips The pins 12 are in close contact with the front shell 1 so that they are electrically connected to the front shell 1 . Since the rear housing 2 is connected to the ground wire, the stainless steel shrapnel 7 is also electrically connected to the ground wire through the conduction between the front housing 1 and the rear housing 2. Therefore, the stainless steel shrapnel 7 forms a ground shielding layer, which effectively shields the rubber seat 4. Signal interference between the nine terminals 6 embedded in injection molding and the ten terminals 14 embedded in injection molding on the lower rubber base 5 .
