Description
Technical field
The present invention relates to electric connector field, especially relate to a kind of full-shield formula differential connector.
Background technology
Differential connector is primarily used to need high speed, the occasion of high-quality transmission signal.Its chief component includes
Shell, difference block and guard shield.Wherein difference block includes insulator and fixing assembling contact on insulator, contact
Including differential pair and grounding pin.One differential connector has usually contained multiple difference block, and shell is provided with and difference block
Corresponding slot and spliced eye corresponding with the inserting section of the contact of difference block, difference block fixation successively arranged side by side is inserted
It is contained in corresponding slot on shell, the inserting section of its contact extends in corresponding spliced eye.
In current differential connector, in order to reduce in signals transmission different difference block differential pair signal it
Between electromagnetic interference, being provided with shielding piece along the direction of routing of differential pair on the side of some difference block, but current difference
Shielding piece on sub-module is all off the inserting section root in contact, and this makes the Plug Division of differential pair not obtain effectively
Shielding processing, therefore current differential connector remains signal big asking of electromagnetic interference when contact inserting section
Topic, this directly affects the signal integrity of whole transmission line.
Content of the invention
It is an object of the invention to provide a kind of full-shield formula differential connector, destroyed with solving existing differential connector
The problem of transmission line signals integrality.
In order to solve the above problems, full-shield formula differential connector employs the following technical solutions：Full-shield formula difference connects
Device, including shell and two or more difference block, difference block includes insulator, differential pair and grounding pin, shell be provided with
Differential pair and the corresponding spliced eye of grounding pin, at least side of insulator is provided with cabling shielding part, between any two difference block
It is respectively provided with described cabling shielding part, at the inserting section at least side of differential pair, be provided with end profile shielding part, any two difference block
It is respectively provided with described end profile shielding part between corresponding differential pair, electrically connect between described end profile shielding part and corresponding cabling shielding part
Connect, shell is provided with perforate corresponding with described end profile shielding part, perforate is mutually isolated with spliced eye.
Described end profile shielding part is the shielding piece at the corresponding side of differential pair.
The edge of described shielding piece is provided with for limiting it to the wing structure of the insertion depth in corresponding perforate.
Described end profile shielding part is electrically connected by directly contact with corresponding cabling shielding part.
The both sides of described insulator are equipped with described cabling shielding part, and the only side in differential pair is provided with described end screen
Shield.
At least side due to the differential pair of the difference block of this full-shield formula differential connector is provided with end profile shielding part, appoints
It is respectively provided with described end profile shielding part between the corresponding differential pair of two difference block of anticipating, and the walking of end profile shielding part and difference block
It is electrically connected between line shielding part.Therefore, during using, end profile shielding part keeps off the differential pair in adjacent two difference block
Inserting section between, thus the electromagnetic interference between the inserting section of the differential pair of the two can be stoped, and then solve existing difference
Connector destroys the problem of transmission line signals integrality.
