It is standby upper.Due to HDMI interface be for transmission of high-definition signal, it is more demanding for the electromagnetic protection of HDMI interface,
To prevent major structure at signal interference.Traditional processing technology needs a large amount of manual scolding tin for the shielding of HDMI interface, i.e., to HDMI screens
It covers shell to be welded, with the gap between the opening and HDMI interface of lock shield shell.However, not only using scolding tin closing
Low production efficiency, and will produce largely useless cigarette, exhaust gas, welding during scolding tin can cause the leak tightness of product unstable,
Electronics width will be generated to environment and penetrates by being directed under product E MI performances.
Invention content
The technical problem to be solved in the present invention is to provide it is a kind of realize it is simple in structure, be easily assembled to, production efficiency is high, shielding
The novel shielding structure of the better HDMI connector of performance.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：A kind of novel shielding knot of HDMI connector
Structure, the HDMI connector include HDMI interface and shielding shell, and the rear portion that shielding shell is fixed in HDMI interface meets HDMI
In the junction block of metastomium is enclosed in, high-definition data line is penetrated from shielding shell and is electrically connected with junction block, it is characterised in that：
It shields and is provided with a circle conductive seal between HDMI interface at the front opening of shell, the inner surface of the conductive seal is tight
It is attached to the outer surface of HDMI interface, and the outer surface of conductive seal then is close to be formed outside to shielding with the inner surface of shielding shell
The sealing structure of shell inner space can be better protected from external interference signal and enter inside HDMI interface.
Further, it is equipped with the envelope that a circle protrudes outwardly in the position that HDMI interface is aligned with the front opening of shielding shell
Oral area, the conductive seal are sleeved on the mouth-sealed portion, and conductive seal is pressed on shielding shell and HDMI interface by mouth-sealed portion
Between gap in, the opening of shielding shell is sealed by mouth-sealed portion and conductive seal cooperation, can reach more excellent close
Envelope and shield effectiveness.
A guide inclined part gradually tapered up backwards is equipped with behind the mouth-sealed portion, the size of the guide inclined part is small
In the size of conductive seal, conductive seal is inserted in from the junction block of HDMI interface, then pack into guide inclined part and along
Guide inclined part is moved along, and is finally sleeved on mouth-sealed portion, and this structure is conducive to be set to junction block by conductive seal is smooth
On, and be conducive to import shielding shell.
Then, shielding shell is inserted in forward from the junction block of HDMI interface, and is moved forward until mouth-sealed portion position will be conductive close
The surface that sealing is pressed on mouth-sealed portion forms sealing structure, and the circuit of junction block is avoided to be interfered by external signal.
Further, the flaring structure towards external expansion is set as at the front opening of the shielding shell, expansion mouth is arc
Shape structure can be more convenient using flaring structure, will more quickly shield shell and HDMI interface assembly.
Preferably, the conductive seal is made of conductive rubber, especially more preferably with electric silica gel.
As a seal part using conductive seal, when assembly, only needs to be compressed conductive seal with shielding shell the present invention
Closed shield structure can be formed on the surface of HDMI interface, assembling is simple, can reduce technology difficulty, production efficiency is made to improve
Cost is greatly reduced in 2 times or more, and is greatly decreased because of the smoke waste gas that gives up caused by welding；The sealing of product can also be improved simultaneously
Shield effectiveness enhances anti electromagnetic wave jamming performance, reduces electronics width and penetrates.
Description of the drawings
Fig. 1 is that the present invention cuts the assembling schematic diagram after shielding shell；
Fig. 2 is decomposition texture schematic diagram of the present invention.
In figure, 1 is HDMI interface, and 2 be shielding shell, and 3 be junction block, and 4 be mouth-sealed portion, and 5 be guide inclined part, and 6 be to lead
Electric sealing element, 7 be flaring structure.
Specific implementation mode
In the present embodiment, referring to Figures 1 and 2, the novel shielding structure of the HDMI connector, which includes
There are HDMI interface 1 and shielding shell 2, shielding shell 2 to be fixed in the rear portion of HDMI interface 1 by the junction block 3 at 1 rear portion of HDMI interface
（It include circuit board）In being enclosed in, high-definition data line is penetrated from shielding shell 2 and is electrically connected with junction block 3；In shielding shell 2
Front opening at a circle conductive seal 6 is provided between HDMI interface 1, the inner surface of the conductive seal 6 is tightly attached to
The outer surface of HDMI interface 1, and the outer surface of conductive seal 7 then is close to be formed outside to shielding with the inner surface of shielding shell 2
The sealing structure of 2 inner space of shell can be better protected from external interference signal and enter inside HDMI interface 1.
It is equipped with the mouth-sealed portion 4 that a circle protrudes outwardly in the position that HDMI interface 1 is aligned with the front opening of shielding shell 2,
