Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

The embodiment provides an ultra-short HDMI adapter, referring to fig. 1 to 3, including a first HDMI interface female socket 1 and a second HDMI interface female socket 2, where the first HDMI interface female socket and the second HDMI interface female socket have the same structure, the first HDMI interface female socket 1 includes a first shielding shell 11, a first metal sheath 12, a first rubber core 13, and a first terminal array 14 integrally injection-molded with the first rubber core 13, the second HDMI interface female socket 2 includes a second shielding shell 21, a second metal sheath 21, a second rubber core 22, and a second terminal array 24 integrally injection-molded with a second rubber core 23, the first HDMI interface female socket 1 and the second HDMI interface female socket 2 are centrosymmetric and have one ends butted with each other, one end of the first terminal array 14 and one end of the second terminal array 24 are butted and welded together, the first shielding shell 11 and the second shielding shell 21 are soldered together, the overall length formed by the first HDMI interface female socket and the second HDMI interface female socket after being butted is less than 20mm, and the length of 19.7mm is preferably adopted in the embodiment.

First shielding shell and second shielding shell are the metal material component, and it has first lateral wall 10A including two protruding 10 and the second lateral wall 10B of three protruding 10, and the first lateral wall 10A of the female seat of first HDMI interface 1 and the second lateral wall 10B of the female seat of second HDMI interface 2 are located the coplanar during equipment, and this is for preventing slow-witted design, makes things convenient for operating personnel to discern, has avoided adorning two the same lateral walls at a plane.

The thickness of the first shield shell 11 and the second shield shell 21 is less than 6.3mm, and 6.27mm (the shortest distance from the first side wall 10A to the second side wall 10B without the projection) is preferably used in this embodiment.

The first terminal array and the second terminal array both comprise 19 pins and can transmit 8K high-definition video signals.

As shown in fig. 4, the product is assembled by first welding and fixing the joint of the first plastic core 13 (integrated injection molding) including the first terminal array 14 and the second plastic core 23 (integrated injection molding) including the second terminal array 24 after connecting the ends with the ends, then respectively installing the first metal sheath 12 and the second metal sheath 22 from the two ends, and since the first metal sheath 12 and the second metal sheath 22 are provided with the fastening holes, in order to avoid electromagnetic interference (electromagnetic waves can pass through the fastening holes), the first shielding shell 11 and the second shielding shell 21 made of fully-enclosed metal are sleeved on the outermost layers, and the joint of the first shielding shell 11 and the second shielding shell 21 is additionally soldered, thereby ensuring the sealing performance, making the overall size extremely short and small, and making the size (length a in fig. 4) 19.7mm, the high-definition video signal transmission device is the minimum value in the existing products, and meanwhile, the outermost layer adopts a fully-closed metal shielding structure, so that the high-definition video signal transmission device has strong electromagnetic interference resistance and can transmit 8K high-definition video signals.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
