Abstract
The invention relates to the field of an electric connector and especially relates to a difference module and a full-shielding-type difference connector using the module. The difference module comprises an insulator, differential pairs and grounding pins. At least one side of the insulator is provided with a wiring shielding member; at least one side of each differential pair is provided with an end shielding member; and the end portion shielding members are in electrical connection with the wiring shielding member. At least one side of each differential pair of the difference module is provided with the end shielding member, and the end shielding members are in electrical connection with the wiring shielding member of the difference module, so that in the using process, when two difference modules coexist, the end shielding members block between the differential pairs of the two difference modules; electromagnetic interference between the differential pairs of the two difference modules can be prevented, and furthermore, the problem that an existing difference connector damages signal integrity of a transmission line is solved.
Description
Technical field
The present invention relates to electric connector field, particularly relate to a kind of difference block and use the full-shield formula differential connector of this module.
Background technology
Differential connector is mainly used to the occasion needing high speed, high-quality transmission signal.Its chief component comprises shell, difference block and guard shield.Wherein difference block comprises insulator and fixing assembling contact on insulator, and contact comprises differential pair and grounding pin.A differential connector often includes multiple difference block, shell is provided with the slot corresponding with difference block and the spliced eye corresponding with the inserting section of the contact of difference block, difference block is successively arranged side by side to be fixedly inserted in slot corresponding with it on shell, and the inserting section of its contact extends in corresponding spliced eye.
In current differential connector, in order to reduce different difference block in signals transmission differential pair signal between electromagnetic interference, the side of some difference block is being provided with shielding sheet along the direction of routing of differential pair, but the shielding sheet in current difference block is all the inserting section roots ending in contact, this makes the Plug Division of differential pair not obtain effective shielding processing, therefore current differential connector still also exists signal through the large problem of contact inserting section electromagnetic interference, and this directly affects the signal integrity of whole transmission line.
Summary of the invention
The object of the present invention is to provide a kind of difference block, to solve the problem that existing differential connector destroys transmission line signals integrality.
Meanwhile, the present invention also aims to provide the differential connector using above-mentioned difference block.
In order to solve the problem, difference block is by the following technical solutions: difference block, comprise insulator, differential pair and grounding pin, the at least side of insulator is provided with cabling shielding part, the at least side of differential pair is provided with end profile shielding part, is electrically connected between described end profile shielding part and described cabling shielding part.
Described end profile shielding part is the shielding sheet at the corresponding side place being located at differential pair.
Described end profile shielding part and corresponding cabling shielding part are by directly contacting electrical connection.
End profile shielding part and corresponding cabling shielding part are fixedly assembled together.
The both sides of described insulator are equipped with described cabling shielding part, are only provided with described end profile shielding part in the side of differential pair.
Full-shield formula differential connector is by the following technical solutions: full-shield formula differential connector, comprise shell and two or more difference block, difference block comprises insulator, differential pair and grounding pin, the at least side of insulator is provided with cabling shielding part, between any two difference block, all there is described cabling shielding part, the at least side of differential pair is provided with end profile shielding part, between the corresponding differential pair of any two difference block, all there is described end profile shielding part, be electrically connected between described end profile shielding part and corresponding cabling shielding part.
Described end profile shielding part is the shielding sheet at the corresponding side place being located at differential pair.
Described end profile shielding part and corresponding cabling shielding part are by directly contacting electrical connection.
End profile shielding part and corresponding cabling shielding part are fixedly assembled together.
The both sides of described insulator are equipped with described cabling shielding part, are only provided with described end profile shielding part in the side of differential pair.
Because at least side of the differential pair of this difference block is provided with end profile shielding part, and be electrically connected between the cabling shielding part of end profile shielding part and difference block.Therefore, in the process used, when two difference block and when depositing, end profile shielding part gear is between the differential pair of the two, thus the electromagnetic interference between the two differential pair can be stoped, and then solve the problem that existing differential connector destroys transmission line signals integrality.
