At present, in auto electronic brake gear, its circuit board generally includes resin bed and line layer, and line layer is arranged on one of resin bed on the surface, and another surface then arranges power source wiring layer.When circuit board being arranged the higher electronic device of power, need the electric current that uses also comparatively high workload, when higher electric current is through power source wiring layer, power source wiring layer easily generates heat and impedance increases, thus affects current delivery.In prior art, normally adopt broadening or increase power source wiring layer, but the volume of this kind of mode meeting increasing circuit plate, is unfavorable for the miniaturization of circuit board, is also unfavorable for reducing production cost.
Utility model content
The utility model in order to solve the problem of prior art, provide a kind of can the current delivery of intensifier circuit plate, and effectively promote the circuit board with wire of circuit board space utilance.
Concrete technical scheme is as follows: a kind of circuit board with wire, comprise power source wiring layer and resin bed, described resin bed is arranged on power source wiring layer, described power source wiring layer is provided with the first wire and the second wire, first, second wire is arranged in resin bed, one end of first wire is provided with the first electrical junction, first electrical junction is welded on power source wiring layer, one end of second wire is provided with the second electrical junction, second electrical junction is arranged on the first electrical junction, connected by joint face between first electrical junction and the second electrical junction, the area of described joint face is greater than the first wire and the second wire cross-section area, described resin bed upper surface is provided with line layer.
It is below attached technical scheme of the present utility model.
Preferably, described joint face is obliquely installed.
Preferably, circuit board comprises through hole, and described through hole runs through the first electrical junction and the second electrical junction.
Preferably, described first electrical junction and the second electrical junction form cylinder, and described through hole is arranged in the middle part of cylinder.
Preferably, described first wire and the second traverse shaft are to crossing.
Preferably, the cross section of described first wire is the first cross section, and the cross section of the second wire is the area equation in the second cross section, the first cross section and the second cross section.
Technique effect of the present utility model: the circuit board with wire of the present utility model can promote the electric current handling capacity of circuit board, reduces the impedance that power source wiring layer produces, reduces the area of power source wiring layer; In addition, the space availability ratio of circuit board can be promoted, reduce the volume of circuit board, be conducive to the miniaturization of circuit board, reduce production cost.
Accompanying drawing explanation
Fig. 1 is the schematic diagram with the circuit board of wire of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the circuit board 100 with wire of the present embodiment comprises power source wiring layer 1 and resin bed 2, and described resin bed 2 is arranged on power source wiring layer 1.Described power source wiring layer 1 is provided with the first wire 11 and the second wire 12, and first, second wire 11,12 is arranged in resin bed 2.First wire 11 one end is provided with the first electrical junction 111, electrical junction 111, first and is welded on power source wiring layer 1.One end of second wire 12 is provided with the second electrical junction 121, electrical junction 121, second and is arranged on the first electrical junction 111.Connected by joint face 3 between first electrical junction 111 and the second electrical junction 121, the area of described joint face 3 is greater than the sectional area of the first wire 11 and the second wire 12, and described resin bed 2 upper surface is provided with line layer 4.Technique scheme connects the first wire and the second wire by joint face, and the area of joint face is greater than first, second wire cross-section area, thus motor current handling capacity, reduce the area of power source wiring layer, promote the utilance of circuit board.
As shown in Figure 1, further, described joint face 3 is obliquely installed, thus can increase the area of joint face 3, thus makes the connection between first, second electrical junction more firm.Circuit board 100 comprises through hole 5, and described through hole 5 runs through the first electrical junction 111 and the second electrical junction 121, and through hole 5 can be used for mounting electronic device.Described first electrical junction 111 and the second electrical junction 121 form cylinder, and in the present embodiment, first, second electrical junction is by being welded to connect.Described through hole 5 is arranged in the middle part of cylinder, thus is convenient to be welded to connect.Described first wire 11 is axially crossing with the second wire 12, thus can meet different board design requirements.In the present embodiment, described first direction, wire 11 place is Y direction, and described second direction, wire 12 place is X-direction, and described X-axis is vertical with Y-axis.The area equation in be the cross section of the first cross section 110, second wire 12 be the cross section of described first wire 11 second cross section, cross section 120, first 110 and the second cross section 120.
The circuit board with wire of the present embodiment can promote the electric current handling capacity of circuit board, reduces the impedance that power source wiring layer produces, reduces the area of power source wiring layer; In addition, the space availability ratio of circuit board can be promoted, reduce the volume of circuit board, be conducive to the miniaturization of circuit board, reduce production cost.
