Abstract

The utility model relates to a high-definition multimedia interface (HDMI) interface structure. The HDMI interface structure comprises a socket and a plug, wherein the plug is fixed in the socket; and the HDMI interface structure is characterized in that a metal shell is sleeved outside the socket and consists of an upper shell and a lower shell which are separated from each other. The HDMI interface structure is simple, only a shell formed by fastening the upper shell and the lower shell together is arranged outside an intermediate product formed by the socket and the plug, and four steps of inner mold injection molding, braid coating, copper foil coating, tin sealing in the prior art are replaced by a single fastening step of the upper and lower shell of the shell, so that the production process is easily controlled, the operation is simple, the productivity and the production yield are improved, and the production cost of an enterprise is reduced.

Description

The HDMI interface structure

Technical field

The utility model relates to a kind of transmission data and uses interface structure, particularly a kind of HDMI interface structure.

Background technology

The HDMI interface is the interface that just occurs recently, and it equally is to transmit digital signal with DVI.Different is that the HDMI interface can not only transmit the high-definition digital video signal, simultaneously the audio signal of high quality.Function is identical with radio frequency interface simultaneously, but owing to adopted totally digitilized signal transmission, the not good situation of image quality can as radio frequency interface, not occur.For the user who does not have the HDMI interface, can still so just lose audio signal with adapter with HDMI interface conversion position DVI interface.High-quality HDMI wire rod even reach 20 meters, also can guarantee the image quality of high-quality.

HDMI is compatible with DVI on stitch, and it equally is to transmit digital signal with DVI, has just adopted different encapsulation.Compare with DVI; HDMI can the transmission of digital audio signal, and HDMI supports the data transmission rate of 5Gbps, can transmit 15 meters farthest; Be enough to deal with the video of a 1080p and the audio signal of one 8 sound channel; Equipment with HDMI has the characteristics of " plug and play ", can carry out " negotiation " automatically between signal source and the display device, selects only video/audio format automatically.

HDMI is backward compatible DVI, therefore can directly connect, as long as there is HDMI-DVI switching adapter just passable.

Traditional in the past connection is an analog signal, or analog signal+digital data transmission.And new HDMI will be complete digital data transmission.

Comprise plug, socket, injection moulding theca interna, braid, copper foil layer, tin layer in the structure of prior art HDMI interface; Production process comprises the welding of HDMI; Plug and socket is fixed together; And outside socket steps such as injection moulding internal mold, copper-clad paper tinsel, envelope tin successively, its whole process of production operation is loaded down with trivial details and be difficult to control, the HDMI interface product qualification rate that causes producing is low.And the shielding rate of Copper Foil is lower, can influence the transmission of data-signal.

The utility model content

The purpose of the utility model provides a kind of HDMI interface structure; These four layers of original injection moulding theca internas, braid, copper foil layer, tin layer have been replaced with an iron-clad in this HDMI interface structure; The simplification of its structure has reduced production stage; Improved production efficiency, easy to control to production process simultaneously, its qualification rate of product of generation is increased.And the shielding of iron-clad is better than the shielding of copper foil layer, therefore can increase shielding rate.

The technical scheme that adopts is:

The HDMI interface structure includes socket, plug, and plug is fixed in the socket, it is characterized in that: suit one metal-back outside socket, metal-back is made up of upper casing that separates and lower casing.

Have bayonet socket on said upper casing and the lower casing respectively, upper casing and lower casing snap together through bayonet socket.

Said metal-back is an iron-clad.

The beneficial effect of the utility model: because in the HDMI interface structure that the utility model is created; These four layers of original injection moulding theca internas, braid, copper foil layer, tin layer have been replaced with an iron-clad; The simplification of its structure has reduced production stage; And the installation of iron-clad only snaps together upper casing and lower casing and gets final product, and has not only improved production efficiency, and production process is more easy to control.Because production stage is few, production process is simple, easy to control, and its qualification rate of product of producing is increased, and reduces the production cost of enterprise.And the shielding of iron-clad is better than the shielding of copper foil layer, therefore can increase shielding rate.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is explained further details.

HDMI interface structure shown in Fig. 1 to Fig. 9 includes socket 1, plug 2, and plug 2 is fixed in the socket 1, suit one metal-back outside socket 1, and metal-back is made up of upper casing that separates 3 and lower casing 4.Said upper casing 3 has bayonet socket 31, and lower casing 4 has bayonet socket 41, and upper casing 3 snaps together through

bayonet socket

31,41 with lower casing 4.In order to make the HDMI interface have better shielding rate, thereby do not influence the transmission of data-signal.The metal-back that adopts in the present embodiment is an iron-clad, except iron-clad, can also adopt the housing of other suitable metal preparations such as aluminium alloy, copper.

Prior art HDMI interface coats braid because the restriction of structure needs the injection moulding internal mold after the HDMI welding, the copper-clad paper tinsel, and envelope tin etc., step is many, and production efficiency is low, and bad control.This patent HDMI interface structure has replaced these four layers of original injection moulding theca internas, braid, copper foil layer, tin layer with an iron-clad; The simplification of its structure has reduced production stage; And the installation of iron-clad only snaps together upper casing 3 and lower casing 4 and gets final product; Improved production efficiency greatly, in technology, can save a lot of times, human and material resources on man-hour.Iron-clad itself just can play excellent shielding effect simultaneously, and effect is better than copper-clad paper tinsel shield effectiveness.In technology, can save a lot of times, human and material resources on man-hour.

The assembling process of above-mentioned HDMI interface structure is as follows:

(1), HDMI welding, socket and plug are fixed together the formation intermediate products;

(2), intermediate products are placed on upper casing inside, again lower shell is contained in outside the intermediate products, and upper casing 3 and lower casing 4 are snapped together through

bayonet socket

31,41;

(3), suit insulation shell outside the iron-clad of upper casing and lower casing formation.

Whole production technology has compared with prior art reduced injection moulding internal mold, coating braid, copper-clad paper tinsel, envelope tin step, makes production process be prone to control.Upper casing 3 directly snaps together through

bayonet socket

31,41 with lower casing 4 simultaneously, makes production convenient, saves time, and has reduced the fraction defective of product, reduces the production cost of enterprise.
