Abstract
The utility model discloses a PCB (printed circuit board) cross coupling piece. The PCB cross coupling piece is applied in a passive cavity and is a PCB provided with a copper sheet layer in the middle. With the adoption of the PCB cross coupling piece, the PCB provided with the copper sheet layer in the middle is adopted to replace the traditional cross coupling rod, but for the traditional cross coupling rod, a copper rod needs to be manufactured firstly and is clamped in a polytetrafluoroethylene medium block to assemble a needed cross coupling rod; the assembly is complex, and manual debugging is inconvenient; and the PCB provided by the invention is shaped in one-time processing, so that the traditional materials are saved, the follow-up assembling is simple, the time and labor are saved, and the cost of the product is furthered reduced.
Description
Technical field
The utility model relates to the coupled apparatus of communications field passive product, especially a kind of PCB cross-couplings sheet.
Background technology
General passive module (putting etc. like duplexer, filter, mixer, tower) in design process, in order to add close coupling, can increase some cross-couplings bars.The application of cross-couplings bar is very general, and structure precision also has relatively high expectations, and in the past, we were through manual manufacture or machine work moulding.Manual manufacture, the difficult control of dimensional accuracy; Machine work, cost are higher relatively.There is following defective in the course of processing of existing coupled apparatus:
Manual manufacture: must be cut into required size with 2 silver-coated copper wire screw mandrel, be stuck in the PTFE medium piece, much also need to add end cap and add close coupling, be assembled into the cross-couplings bar that needs usefulness at two ends;
The machine work moulding: the aluminium of machine work moulding or copper bar are stuck in the PTFE medium piece, are assembled into the cross-couplings bar that needs usefulness;
Cost of labor is high: the size that 1. manual manufacture must control cross-couplings bar, and general error requirements is at ± 0.05mm, and is artificially with slide calliper rule control, very time-consuming; 2. the good screw mandrel of machine work also needs artificial assembling to be shaped, and consuming time relatively, the machine work expense is high; 3. artificial assembling is because low precision has increased debugging difficulty, and debug time prolongs naturally;
Waste material: because the Artificial Control low precision, assembling process portion size can occur and do weak point, has wasted material;
The product delivery rate is slow: because the course of processing is complicated, reasons such as debug time length have finally caused the delivery rate of passive product slow.
The utility model content
The technical problem that the utility model will solve is: a kind of PCB cross-couplings sheet is provided, and this PCB cross-couplings sheet time processing moulding, simple in structure, and be convenient to follow-up assembling, saved human cost when saving material.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of PCB cross-couplings sheet is applied to passive cavity, and said PCB cross-couplings sheet is the middle pcb board that is provided with the copper sheet layer.
Preferably, said pcb board has the location hole that is used for fixing on said passive cavity, and said location hole attachment screw is fixed on pcb board on the passive cavity.
Further as preferred embodiment, the aperture of location hole place copper sheet layer is greater than the aperture of pcb board insulating medium layer on the said pcb board.
Further, be provided with an insulating washer on the said pcb board between location hole and the screw as preferred embodiment.
Further as preferred embodiment, said screw is that insulating material is processed.
Further as preferred embodiment, said insulating material is a polytetrafluoroethylmaterial material.
The beneficial effect of the utility model is: the pcb board that is provided with copper sheet in the middle of the utility model PCB cross-couplings sheet adopts has replaced traditional cross-couplings bar; And traditional cross-couplings bar needs to make earlier the copper bar; And the copper bar is stuck in is assembled into the cross-couplings bar that needs in the PTFE medium piece; Assembling is complicated, the manual debugging trouble; The moulding of the utility model pcb board time processing saved traditional material, and follow-up assembling is simple, and is time saving and energy saving, also further reduced the cost of product.
Description of drawings
Be described further below in conjunction with the embodiment of accompanying drawing the utility model:
Fig. 1 is the example structure sketch map that the utility model PCB cross-couplings sheet is applied to passive cavity.
Embodiment
The utility model PCB cross-couplings sheet is applied to passive cavity, passive module such as passive cavity filter, duplexer for example, and said PCB cross-couplings sheet is the middle pcb board that is provided with the copper sheet layer.
In a preferred embodiment, with reference to Fig. 1, comprise cavity 1 ~ 6 and cavity a ~ f in the passive cavity 10, PCB cross-couplings sheet is the middle pcb board 20 that is provided with the copper sheet layer.Pcb board 20 has replaced traditional cross-couplings bar, is used to strengthen the coupling between the non-conterminous cavity, as in Fig. 1, there being 3 pcb boards 20, strengthened cavity 1 and 3,3 and 5 and a and c between coupling.Be merely here and illustrate, it will be understood by those skilled in the art that the application of the utility model PCB cross-couplings sheet can be different and different according to the structure of passive cavity 10.
Preferably, said pcb board 20 has the location hole that is used for fixing on said passive cavity 10, and said location hole attachment screw 30 is fixed on pcb board 20 on the passive cavity 10.In the utility model, only need a screw can pcb board 20 be fixed on the passive cavity 10 like this, assembling process is simple.
Further as preferred embodiment, in order to prevent short circuit between pcb board 20 and the screw 30, the aperture of location hole place copper sheet layer is greater than the aperture of pcb board insulating medium layer on the said pcb board 20.
Further as preferred embodiment; Be provided with an insulating washer 40 on the said pcb board 20 between location hole and the screw 30; Said insulating washer 40 can adopt polytetrafluoroethylmaterial material to process or the dielectric layer material of pcb board is processed, to guarantee electric insulation between screw 30 and the pcb board 20.
Further as preferred embodiment, said screw 30 is processed for insulating material.For example adopt polytetrafluoroethylmaterial material to process or the dielectric layer material of pcb board is processed, like this can be without insulating washer 40, directly utilize screw 30 and location hole on the pcb board 20 to combine pcb board 20 is fixed on the passive cavity 10.
The utility model adopts pcb board 20 to replace the cross-couplings bar of traditional application and passive module, has saved cost of manufacture, and processing technology is simple, and convenient for assembly.
More than be that preferable enforcement to the utility model specifies; But the utility model is created and is not limited to said embodiment; Those of ordinary skill in the art can also make all equivalent variations or replacement under the prerequisite of the utility model spirit, distortion that these are equal to or replacement all are included in the application's claim institute restricted portion.
