Abstract
The utility model discloses a PCB board of network transformer, including the PCB plate body, be equipped with plug -in hole on the PCB plate body, plug -in hole is wineglass form hole, and wineglass form hole is by the cylinder hole of the trapezoidal hole on upper portion and the lower part structure that fuses, and is narrow under the last width of trapezoidal hole, does trapezoidal hole leave for 0.01 with the profiled sheeting back gauge of PCB plate body 0.03mm. This PCB board of network transformer adopts the cupped plug -in hole structure of wine, and the cupped trapezoidal hole of wine has certain clearance of inserting with plug -in components, and cylinder hole part is far away comparatively with the distance of the shaping flange of PCB plate body, keep the cupped plug -in hole of wine when pegging graft or during the pad circumstances of broken hole and nos rosin joint take place, and the dimensional requirement of plug -in hole's appearance and structure is strict, the error is little, the complete orifice of plug -in hole hot air solder leveling ability.
Description
Technical field
This utility model relates to the technical field of a kind of pcb board, the pcb board of the network transformer particularly relate to a kind of to be applied on the transformator of networking, replace traditional cylindrical hole with the insert hole of goblet shape, preventing from holes situation from occurring.
Background technology
At present, existing use pcb board on network transformer need to arrange insert hole formed with the plug-in unit of electronic component and network transformer be connected, welding etc..Conventional insert hole is cylindrical bore, due to network transformer and the size limitation of plug-in unit, position limitation etc., the overall dimensions of insert hole necessarily requires requirement, and the molding edges of boards of insert hole distance pcb board body necessarily be in the nearest situation, i.e. insert hole is substantially the molding edges of boards being adjacent to pcb board body, the distance that both are the thinnest, just as the distance of a thin paper；It addition, also need to carry out insert hole spraying stannum.Owing to the dieplate back gauge of insert hole Yu pcb board body is close and the restriction of cylindrical-shaped structure, when plug-in unit inserts insert hole, easily cause the holes of insert hole, and owing to insert hole processes the thinnest position with the dieplate back gauge of pcb board body, existing tin spray process is can not be to the complete spray orifice in whole hole of insert hole, additionally, the situation that holes can cause rosin joint occurs.
Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome above-mentioned prior art, the pcb board of a kind of network transformer is provided, the pcb board of this network transformer uses the insert hole configurations of goblet shape, the trapezoidal hole of goblet shape and plug-in unit have certain insertion gap, and cylindrical hole portion is the most remote with the distance of the molding edges of boards of pcb board body, when grafting or during pad, holes and the situation without rosin joint do not occur to keep the insert hole of goblet shape, and the dimensional requirement of the profile of insert hole and structure is strict, error is little, and insert hole spray stannum can complete spray orifice.
This utility model solves its technical problem and be the technical scheme is that the pcb board of a kind of network transformer, including pcb board body, it is provided with insert hole in pcb board body, insert hole is goblet shape hole, goblet shape hole is connected structure by the trapezoidal hole on top and the cylindrical hole of bottom, and trapezoidal hole is wide at the top and narrow at the bottom；Trapezoidal hole is 0.01-0.03mm with the dieplate back gauge of pcb board body.
Further, described insert hole is provided with spray stannum.
Further, the height of described trapezoidal hole is 0.7mm, and the height of cylindrical hole is 0.5mm.
In sum, the pcb board of network transformer of the present utility model uses the insert hole configurations of goblet shape, the trapezoidal hole of goblet shape and plug-in unit have certain insertion gap, and cylindrical hole portion is the most remote with the distance of the molding edges of boards of pcb board body, when grafting or during pad, holes and the situation without rosin joint do not occur to keep the insert hole of goblet shape, and the dimensional requirement of the profile of insert hole and structure is strict, error is little, and insert hole spray stannum can complete spray orifice.

Fig. 2 is the partial schematic sectional view of the pcb board of a kind of network transformer of this utility model embodiment 1.
Detailed description of the invention
Embodiment 1
The pcb board of a kind of network transformer described by the present embodiment 1, as depicted in figs. 1 and 2, including pcb board body 1, it is provided with insert hole 2 in pcb board body, insert hole is goblet shape hole, and goblet shape hole is connected structure by the trapezoidal hole 3 on top and the cylindrical hole 4 of bottom, and trapezoidal hole is wide at the top and narrow at the bottom；Trapezoidal hole is 0.01-0.03mm with the dieplate back gauge of pcb board body.
This insert hole is provided with spray stannum.
The height of this trapezoidal hole is 0.7mm, and the height of cylindrical hole is 0.5mm.
The above, be only preferred embodiment of the present utility model, and structure of the present utility model is not made any pro forma restriction.Every any simple modification, equivalent variations and modification made above example according to technical spirit of the present utility model, all still falls within the range of the technical solution of the utility model.
