Background technology
It generally is with the naked sky in the bottom of base that existing network becomes device, and then is arranging around pin, but since around pin in horizontal plane terminal mainboard PCB space apart from little, can have the safety problem, thereby make the potential bad risk of complex manufacturing and stream tin sweat(ing), non-refractory.Easy when scale of mass production, usually production has some setbacks, and has improved production cost.In addition, existing network becomes the packaging technology complexity of device, the skewness when pin and cause the bad phenomenon of wicking.
Summary of the invention
The problem that the present invention need solve provides four-hole 100,000,000 network transformers that a kind of simple in structure, packaging technology section is single, be applicable to the 48PIN encapsulating structure of extensive operation.
To achieve these goals, the present invention designs a kind of four-hole 100,000,000 network transformers of 48PIN encapsulating structure, include the base of square insulation, the upper end open of described base is provided with loam cake above base, be provided with several coils in base, be provided with one in the base arranged on both sides and arrange 24 around pin, described loam cake is connected with the prolongation sheet, prolongs the sheet inwall and is provided with projection, and the both sides that base prolongs sheet relatively are provided with the salient point that matches with projection.
24 winding terminals around pin of a described row are embedded on the base bilateral wall setting that is in staggered distribution mutually of the adjacent winding terminal around pin.
Described winding terminal around pin is provided with groove.
Described loam cake both sides are respectively equipped with several through holes.
Four-hole 100,000,000 network transformers of 48P worker N encapsulating structure of the present invention adopt upper and lower covers to encapsulate the potential bad risk that the assembly type structural design is effectively improved traditional Open Header naked hollow structure complex manufacturing in bottom and flowed tin sweat(ing), non-refractory.The present invention can improve the production first-pass yield and reduce production costs; Simple for assembly process.Of the present invention when pin the enamelled wire termination recess that can evenly distribute, well optimize conventional process flow, reduced at tradition skewness and cause the bad phenomenon of wicking on pin.The present invention adopts the design of upper and lower covers buckle-type, and is simple for assembly process, and structural design is novel unique, effectively strengthens the intensity of combination.Of the present inventionly adopt symmetrical T shape structure around foot, the enamelled wire termination recess that can evenly distribute is well optimized conventional process flow when pin, has reduced at tradition skewness and cause the bad phenomenon of wicking on pin.

Embodiment
For the ease of those skilled in the art's understanding, structural principle of the present invention is described in further detail below in conjunction with specific embodiment and accompanying drawing:
As Fig. 1, Fig. 2, shown in Figure 3, a kind of embodiment of four-hole 100,000,000 network transformers of 40PIN encapsulating structure.It includes the base 1 of square insulation, the upper end open of described base 1, above base 1, send out and be equipped with loam cake 2, be provided with several coils 71 li of base, be provided with one in base 1 arranged on both sides and arrange 20 around pin 3, described loam cake 2 is connected with and prolongs sheet 4, prolongs sheet 4 inwalls and is provided with projection, and the both sides that base 1 prolongs sheet 4 relatively are provided with the salient point 6 that matches with projection.24 winding terminals around pin 3 of one row are embedded on base 1 two side setting that is in staggered distribution mutually of the adjacent winding terminal around pin 3.Described winding terminal around pin 3 is provided with groove 8.Described loam cake 2 both sides are respectively equipped with several through holes 9.
Four-hole 100,000,000 network transformers of 48PIN encapsulating structure of the present invention, adopt the upper and lower covers Combination Design, be applied to the network switching equipment, support the 10/100Base-T transmission rate, electrical parameter and performance meet the IEEE802.3 international standard, and electromagnetism inhibition ability meets EN55022 Class B standard-required.Signal transmission, impedance matching, signal noise suppress, high voltage is isolated, conventional PoE function.
The present invention 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 100Ohm, can effectively control ReturnLoss.
C, common-mode signal clutter suppress: 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, make its a large amount of decay, thereby reach the purpose that suppresses common mode EMI, meet EN55022 Class B standard-required.
D, high voltage are isolated L: product magnet assembly design insulation voltage satisfies IEEE802.3.2002.PARA 40.6.1.1, ITEM a﹠amp; The b requirement; the varying level of isolating heterogeneous networks equipment room in the netting twine connection; make die terminals and external isolation; antijamming capability strengthens greatly; and chip increased very big protective effect (as thunderbolt); to prevent that different voltages from transmitting damage equipment by netting twine, can play certain lightning protection and shock resistance protective effect to customer equipment thus.
E, conventional PoE function: product meets the IEEE802.3af international standard,, this product possesses the PoE/350mA function of supplying power, and power is 13.5W, allows Ethernet to transmit DC power supply simultaneously on data line.
Base of the present invention adopts mode Contiuum type in flakes when making, can be earlier around leading portion operations such as pin, formerly the blank sheet is in integrated testability, well optimize conventional process flow, reduced and on the traditional test operation, caused the bad order phenomenon, save manpower and man-hour, can effectively reduce the product processing cost.
Foregoing is preferred embodiment of the present invention only, is not to be used to limit embodiment of the present invention, and those skilled in the art are according to design of the present invention, and appropriate adaptation of having done or modification all should be within protection scope of the present invention.
