Description

The improvement of signal filtering modular structure

Technical field

The utility model relates to a kind of signal filtering module, particularly a kind of improvement of signal filtering modular structure.

Background technology

Along with electronics and IT products move towards sophistication, the technology that electronic component is connected on the printed circuit board (PCB) is taked surface adhesive type (SMD) now mostly, be example wherein for the RJ-45 connector of using with network, carrying out signal when transmission at the RJ-45 connector, all can produce electromagnetic interference to electronic component on every side or circuit, and then cause the signal transmission to make a mistake, and above-mentioned electromagnetic interference can be radiated in the air again and disturb other radio broadcasting receiver, and then influence other Local Area Network, therefore just need in connector, to be provided with filtration module, yet this filtration module is for being designed to the wafer kenel, and on the wiring board of applicable circuit board that is welded in various signal transmitting apparatus or interface card (be not limitation RJ-45 go up use), and reach and suppress electromagnetic interference and keep the complete of signal, so, the external network signal that network connector received can be carried out the filtering action, further eliminate unnecessary noise, and the actual useful signal of reservation, so that network signal is passed to the data transmission interface of normalization such as external control circuit interface, and this network signal is converted to the tandem data transfer signal, just can in data handling system, handles at last.

Please consult Fig. 7 simultaneously, shown in 8, be existing three-dimensional exploded view and side cutaway view, find out by knowing among the figure, this type of signal filtering module includes insulating base frame A, splicing ear B, filtering unit C and insulation loam cake D form, wherein splicing ear B inlays in conjunction with on (INSERTMOLDING) insulating base frame A two sidewall A1 by the mould ejection formation, and splicing ear B is through to the top by sidewall A1 bottom, and the lead C1 of filtering unit C is wound on the kinking post B2 of splicing ear B at sidewall A1 top, connect via welding again, be bent with in addition pin B1 with the copper platinum face E1 welding of circuit board E in splicing ear B bottom, this signal filtering module opposite side has symmetrical structure to connect, the final signal linkage function that realizes, but during its actual processing operation, be the following disappearance of deriving:

Very time-consuming when (one) the lead C1 kinking post B2 that is wound in splicing ear B goes up, must every lead C1 be wound on the kinking post B2 one by one and be welded to connect, cause the processing procedure cost to increase and the operation process complexity difficult.

(2) the pin B1 of splicing ear B and kinking post B2 run through respectively and are positioned at sidewall A1 upper and lower, so its splicing ear B must be provided with the structure length setting that is higher than insulating base frame A height, and then the problem that causes splicing ear B material cost to improve.

(3) kinking post B2 and lead C1 junction are the sidewall A1 top that is positioned at insulating base frame A, for its insulating base frame of needs A top of satisfying processing procedure must be Openworks shape, therefore promptly must increase that insulation loam cake D guarantees that signal filtering module outward appearance and filtering unit C are exposed and it is electric bad to cause, and then increase processing procedure and the cost problem of assembling insulation loam cake D.

Therefore, how to manage to solve flaw problems such as above-mentioned existing existing process operations difficulty, fraction defective height and cost increase, be the direction place that the desire research of relevant dealer institute improves.

Because above-mentioned existing apparatus is all undesirable in design, therefore, the creator collects related data, via assessing in many ways and considering, and engaging in the many years of experience of the industry accumulation, and, adhere to continuous research improvement creative ideas in line with excelsior spirit, at above-mentioned deficiency locate improved again, be the improvement of designing and developing out the utility model signal filtering modular structure.
