Description
Technical field
The invention relates to a kind of inductor (Inductor), and particularly relevant for a kind of signal distribution inductor (Signal Distributing Inductor).
Background technology
Along with electronics telecommunication and development of Internet, often need the telecommunication path be distributed in many cases, use to make things convenient for more users.For instance, the lane assignment of cable TV is generally dendroid network system, so cable television operators need at each breakout circuit to be done equivalence and distribute, and just can make each client obtain identical service.
The sketch map that is disposed at a circuit board for existing two signal distribution inductors shown in Figure 1.Please refer to Fig. 1, existing signal distribution inductor 110 and 120 induction body 112 and 122 are through being disposed on the circuit board 10 by the winding of coil 114 with coil 124, and then form a component road circuit.Yet described shunt circuit only can meet old electrical specification, and its electrical specification for current cable bi-directional digital transmission signals still has one section gap.In addition, because signal distribution inductor 110 must be accomplished via manually-operated mode with signal distribution inductor 120 is assembled to circuit board 10 from winding the line to process, therefore said technology will expend more human cost and built-up time.On the other hand, the quality of signal distribution inductor also significantly reduces because of the error that manual operation caused easily.
Fig. 2 A is depicted as the sketch map that existing another kind of signal distribution inductor is assembled to a circuit board.Please refer to Fig. 2 A, existing signal distribution inductor 200 mainly comprises a pedestal 210, an induction body 220 and a plurality of coils 230.Pedestal 210 has a plurality of pins 212, and induction body 220 is provided with a plurality of perforation 222 (Fig. 2 A illustrates 2).Can be known that by Fig. 2 A coil 230 is to be set around between pin 212 and the perforation 222 with the mode that winds the line, wherein coil 230 electrically connects with pairing pin 212, and pin 212 is electrically connected to circuit board 20.It should be noted that this technology only needs single induction body 220 can reach the purpose of signal allocation, has simplified the process that signal distribution inductor 200 is assembled to circuit board 20.In addition; Because existing signal distribution inductor 200 has an absorption plane 240, therefore one be applicable to that the board of surface mount processing procedure (Surface Mounting Process) can be via drawing absorption plane 240 so that signal distribution inductor 200 is assembled to circuit board 20.Compared to manually-operated mode signal distribution inductor 200 being assembled to circuit board 20, this technology has preferable processing procedure efficient and processing procedure quality.Yet; Because described signal distribution inductor 200 only has an induction body 220; Therefore work as signal distribution inductor 200 in working order down, the inside of induction body forms the magnetic circuit of sealing easily, causes magnetically saturated phenomenon (to please refer to Fig. 2 B; It is depicted as the sketch map of the sealing magnetic circuit that is produced in the induction body 220 of Fig. 2 A), cause the operating efficiency of signal distribution inductor 200 to reduce.
