Embodiment
For the ease of those skilled in the art's understanding, structural principle of the present utility model is described in further detail below in conjunction with specific embodiment and accompanying drawing:
As Fig. 1, Fig. 2, shown in Figure 3, design a kind of embodiment of gigabit networking transformer of ultra-thin encapsulating structure.It includes the base 1 of square insulation, the upper end open of described base 1, above base 1, be provided with loam cake 2, the both sides of described loam cake 2 are extended with segmental arc 4 around pin 3 to be provided with 12 of rows in base 1 arranged on both sides, and segmental arc 4 is provided with several through holes 5, through hole 5 is provided with projection 6, the both sides of described base 1 relative segmental arc 4 are provided with depression 7, and loam cake 2 covers when the upper end of base 1, and projection 6 snaps in 7 li of depressions.Described winding terminal around pin 3 is provided with groove 8.Described loam cake 2 and the thickness after base 1 fastens are less than or equal to 2.5mm.
The gigabit networking transformer of the ultra-thin encapsulating structure of the utility model be that the total height of 24PIN SM has only 2.5mm around pin, be applied to the network switching equipment, notebook computer, support the 10/100/1000Base-T transmission rate, electrical parameter and performance meet the IEEE802.3 international standard, and electromagnetism inhibition ability meets EN55022 Class B standard-required.This product structure design uniqueness, good reliability can reduce the mainboard space, makes things convenient for the specific (special) requirements of the miniaturization of client's volume, function diversification.Signal transmission, impedance matching, signal noise suppress, high voltage is isolated, conventional PoE function.
The utility model also has following characteristics:
A, signal transmission: support 10/100/1000 Base-T transmission rate, electrical parameter and performance meet the IEEE802.3 international standard, each passage can be defined as different function (as transmission or receive path) according to different mainboard chips, it is coupled filtering to the differential signal that PHY sends out with enhancing signal with the differential mode coupling coil, and is coupled to an other end of the connection netting twine of varying level by the conversion of electromagnetic field.
B, impedance matching: the impedance of coupling client mainboard 100 Ohm, can effectively control ReturnLoss.
C, the common-mode signal clutter suppresses: increase common mode choke coil in the product magnet assembly, when producing opposite magnetic field during by co-mode coil in magnetic core, the differential mode signal cancels out each other, the magnetic field that produces equidirectional when common-mode signal during by coil in magnetic core is strengthened, it can make, and useful difference mode signal is almost loss-free to be passed through, and common mode interference signal is presented high impedance, makes its a large amount of decay, thereby reach the purpose that suppresses common mode EMI, meet EN55022 Class B standard-required.
