Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.

Referring to figs. 1 to 4, it the present embodiment provides a kind of HDMI connector structure, including signal terminal 1, plastic part 2 and leads Electric module 3.The signal terminal 1 includes a plurality of shielding earth terminals 101；One end of the signal terminal 1 and the plastic cement Portion 2 is affixed, and the top of the plastic part 2 position at least corresponding with the shielding earth terminal 101 is equipped with through hole 201； Conductive module 3 is made of conducting medium, and the bottom of the conductive module 3 has extended downwardly several conductive prominences 301, at least one institute It states conductive prominence 301 and is connected across the through hole 201 with the corresponding shielding earth terminal 101.

In the present embodiment, the quantity of shielding earth terminal 101 is 4.Preferably, the quantity of the conductive prominence 301 is not Greater than the quantity of the shielding earth terminal 101, and each conductive prominence 301 with a shielding earth terminal 101 connect.Preferably, the conductive prominence 301 is identical as the quantity of both shielding earth terminals 101.

Specifically, after conductive prominence 301 and the shielding earth terminal 101 connect, shielding earth terminal 101 is logical The electric field generated after electricity can change, to reach jamproof purpose, improve signal transmission quality.It is understood that With increasing for 301 quantity of conductive prominence, the anti-interference ability of HDMI connector structure is gradually increased, when the conductive prominence 301 conductive prominences 301 identical and each with the quantity of both shielding earth terminals 101 with a shielding earth end When son 101 connects, HDMI connector structure has preferably anti-interference ability.

In the present embodiment, the conductive module 3 is different from the dielectric constant of both plastic parts 2.Further, the conduction Module 3 is metal material.

Specifically, the conductive module 3 and the dielectric constant difference of both plastic parts 2 can make shielding earth terminal 101 The electric field generated after energization can change, further, the difference in dielectric constant of the conductive module 3 and both plastic parts 2 More significant, electric field change is more obvious, and anti-interference ability is stronger.It is understood that being led when conductive module 3 is metal material The difference in dielectric constant of electric module 3 and plastic part 2 is larger, can get preferable anti-jamming effectiveness.

In the present embodiment, the top of the plastic part 2, which is recessed downwards, forms lateral T-slot, and the through hole 201 is located at The slot bottom of the T-slot；The shape and size of the conductive module 3 and the T-slot match and with the T-slot grafting. Further, the slot bottom of the T-slot has upwardly extended positioning convex platform 202, the conductive module 3 and the positioning convex platform 202 Corresponding position is equipped with the slot 302 with 202 grafting of positioning convex platform.Specifically, the connection type of grafting may be implemented to lead It rapid-assembling/disassembling between electric module 3 and plastic part 2 and is bonded.

Preferably, the conductive prominence 301 is pliable elastomeric members, and shielding ground can be withstood by the deformability of itself Line terminals 101.Further, conductive prominence 301 can be spring-piece type structure, can also be made of the preferable material of elasticity. It is understood that when conductive prominence 301 has preferable elasticity, conductive prominence 301 can be by itself deformability Shielding earth terminal 101 is withstood, is conducive to make conductive prominence 301 to contact with shielding earth terminal 101 more closely and sufficiently, no Easily there is poor contact.
