Abstract
A high speed high density electrical connector shielding complementarily is provided, which consists of a hole connector and a needle connector. The hole connector comprises a differential signal pair, a shell and laminate components; the laminate components are positioned in the shell and are composed of left laminate components and right laminate components; the left and right laminate components are arranged at intervals; shield sheets among columns on the left and right laminate components are complementary in position. The utility model adopts two-piece shield sheets among columns, realizes complementary shielding and is good in shielding effect of the products, simple in structure, low in material cost and processing cost of products and good in application effect.
Description
One, technical field
The utility model relates to a kind of electric connector, relates in particular to a kind of high-speed and high-density electrical connector that is used for transmission complementary shielding between the printed circuit board (PCB).
Two, background technology
Frequency/the transfer rate of telecommunications, data communication, microprocessor, memory bus and Ethernet constantly (is for example promoting, before 3 years, data-signal speed on the pcb board also has only 1Gbps, now has reached 5Gbps, even will rise to 10Gbps) time, in the High Speed System, require the volume of connector to do littler and littler.Therefore, in order to guarantee the integrality of High Speed System signal, designed high density, microminiaturized connector are not only required in the impedance balance of each contact in the terminal module, to reduce signal lag and reflection, and require to shield between each rows of terminals, to reduce crosstalking between the transmission line.
The high-speed and high-density electrical connector of existing band shielding adopts and insert the signal integrity that earth shield sheet method is improved connector between adjacent signals contact row, as with of the shape moulding of a plurality of shielding blades according to right-angle cross-section, keep apart each signal pins, for each signal pins is equipped with a corresponding ground shield.
But the electric connector of said structure also exists deficiency and defective at aspects such as transmission rate, shield effectiveness or Project Realization expenses, is difficult to satisfy higher level demands such as two-forty, high density and low cost.
Three, summary of the invention
The purpose of this utility model is: at the ubiquitous problem of above high-speed and high-density electrical connector, provide a kind of simple in structure, the high-speed and high-density electrical connector of the complementary shielding of lower cost for material.
The high-speed and high-density electrical connector of complementary shielding described in the utility model is made up of hole connector and needle connector, hole connector comprises that differential signal is to, shell and laminate assembly, the laminate assembly is installed in the enclosure, the laminate assembly is made up of left laminate assembly and right laminate assembly, described left and right laminate assembly is formed by shield blade and laminate between two row, the shield blade symmetry is installed on the two sides of its laminate between row, above-listed shield blade locations complementary of left and right laminate assembly, left and right laminate assembly is spaced during assembling.
For improving the high-speed and high-density electrical connector shield effectiveness, shield blade is installed in the diverse location up and down of laminate assembly respectively between row, forms complementary shielding.Shield blade is saved shield blade material cost and processing cost so greatly by metallic plate punch process once-forming between row.
The high-speed and high-density electrical connector of the utility model complementary shielding adopts shield blade between the two-piece type row, realizes complementary shielding, and shield effectiveness is good, and is simple in structure, and product material cost and processing cost are low.

Five, embodiment
Below in conjunction with accompanying drawing embodiment the high-speed and high-density electrical connector of the utility model complementary shielding is described in further detail:
Be illustrated in figure 1 as the high-speed and high-density electrical connector structural representation of the utility model complementary shielding.The utility model electric connector is made up of hole connector 1 and needle connector 2.Hole connector 1 comprises that differential signal is to structures such as (not marking among the figure), shell 3 and laminate assemblies 4.Laminate assembly 4 is installed in the shell 3.
Laminate assembly 4 is divided into two kinds of structures: left laminate assembly 4a and right laminate assembly 4b.Laminate assembly 4 is spaced by left laminate assembly 4a and right laminate assembly 4b, and the laminate assembly 4 that forms a whole is installed in the shell 3 then.
Figure 2 shows that the high-speed and high-density electrical connector left side laminate assembly 4a structural representation of the utility model complementary shielding, described left laminate assembly 4a is made up of shield blade 9a and laminate 11 between two row, shield blade 9a symmetry is installed on the two sides of laminate 11 between row, shield blade 9a is provided with several claws 5, palmate shield blade 6 and grounding pin 7 between every row, claw 5 is in order to block laminate 11, two palmate shield blade 6 contact right pin with differential signal and are surrounded, play shielding action, grounding pin 7 is grounded shielding with shield blade 9a ground connection between whole row.Laminate 11 is provided with shield blade 9a upper clipping claw 5 corresponding holes 10 between several and row.
Fig. 3 is the right laminate modular construction of the high-speed and high-density electrical connector schematic diagram of the utility model complementary shielding.
Laminate assembly 4b and the difference of left laminate assembly 4a are to be listed as shield blade 9a, a 9b, and the installation site of its laminate is different relatively.The top of slightly close its laminate 11 of shield blade 9a between the row of left side laminate assembly 4a, shield blade 9b position is near the laminate below between the row of right laminate assembly 4b, after left laminate assembly 4a and right laminate assembly 4b assemble at interval, shield blade 9a and 9b locations complementary between its row just in time form the laminate assembly 4 of a complementary shielding.
