Abstract
The utility model discloses a circuit board of a welding machine, comprising a base plate and a circuit printed at front of the base plate, wherein the circuit is provided with a plurality of circuits, at least one of which is connected in parallel with a metal plate wire being capable of converging current. As the circuit, on which heavy current flows through intensively, is connected with the metal plate wire in parallel, the converged current output capability of the circuit board can be enhanced since the metal plate wire can converge the output of the heavy current, the heavy current is avoided from flowing through a printing plate for a long time to burn out the circuit board, and the service life of the circuit board is prolonged.
Description
Technical field
The utility model relates to a kind of bonding machine circuit board.
Background technology
Traditional welding machine circuit plate, it comprises substrate, be printed on the circuit on the substrate back and the output of connecting circuit, this circuit has many circuits.Existing bonding machine circuit board has following deficiency: 1, because the welding machine output current is big, so the electric current of certain the bar line flows warp in the circuit board is excessive, and circuit board burns out easily; 2, external circuits is that direct bolt is exported to derive big electric current on exit point, and directly bolt damages circuit board easily.
The utility model content
The utility model provides a kind of bonding machine circuit board, and it has overcome the deficiency that the existing circuit board of traditional welding machine circuit plate burns out easily, damages easily.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of bonding machine circuit board, it comprises substrate and is printed on circuit on the substrate back, this circuit has many circuits, has at least on the circuit in these many circuits and is connected to a metal printed line that can compile electric current.
In the utility model one preferred embodiment: this metal printed line is a copper cash.
In the utility model one preferred embodiment: this metal printed line is located at substrate front side, and substrate is passed and be welded in these metal printed line many places, and the protruding end that this metal printed line passes substrate by many places is welded on the printed wire.
In the utility model one preferred embodiment: this circuit board also comprises an output afflux terminal, and this output afflux terminal adopts copper coin directly to draw, and this copper coin is fixed on the substrate.
In the utility model one preferred embodiment: this copper coin is fixed in substrate back.
The technical program is compared with background technology: because on the circuit that big electric current is flowed through and the metal printed line arranged, therefore the metal printed line can be shared the part electric current of big electric current, electric current handling capacity that can accentuator printed line road, can avoid big electric current to burn out circuit board, can prolong circuit board useful life.Because the metal printed line adopts copper cash, so resistivity is low, long service life.Because the metal printed line is located at substrate front side, these metal printed line many places are passed and are fixed on the printed wire, this metal printed line compiles electric current directly lead line plate outer end, back respectively, so fixing between copper cash, copper cash and the substrate, can not have influence on the circuit working of circuit board.Form because output directly extends from the copper coin line, external circuits prolongs Shen end connecting circuit by the copper coin line, and therefore not fragile circuit board can prolong circuit board useful life.Because the copper coin line is fixed in substrate back, so the copper coin line can not have influence on the circuit working of circuit board.
Accompanying drawing is said
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 has illustrated the front schematic view of the bonding machine circuit board of a preferred embodiment.
Fig. 2 has illustrated the schematic rear view of the bonding machine circuit board of a preferred embodiment.
Label declaration: circuit 11, copper coin line 12, copper coin line terminals 13.
Embodiment
Please refer to Fig. 1 and Fig. 2, a kind of bonding machine circuit board, it comprises substrate and is printed on circuit on the substrate back, this circuit has many circuits, has at least on the circuit 11 in these many circuits and is connected to a copper coin line 12 that can compile electric current.Understand structure of the present utility model for the reader can be known, only illustrate and be connected to the circuit of copper coin line among the figure, other circuit is not drawn.This copper coin line 12 is located at substrate front side; These copper coin line 12 end points pass the through hole of substrate, by welding copper coin line 12 end points are fixed on the printed wire of substrate again; These copper coin line 12 end points are compiled electric current respectively and be connected on the circuit 11.Among the present embodiment figure, only illustrated two circuits 11, but not as limit, in this multi-line, as long as the electric current of line flows warp is big electric current, all can adopt mode above-mentioned and that connect the copper coin line, to share big electric current and electric current is used outside the exit point lead line plate.
This circuit board also comprises the lead-out terminal of an electric current connecting circuit, and this lead-out terminal adopts the Shen end that prolongs of copper coin line directly to punch 13, and this lead-out terminal is fixed in substrate back.This affixed can be in the following way: perforate on the substrate, the copper coin line is provided with projection, this projection passes perforate, by welding projection is fixed on the printed wire of substrate, with lead-out terminal 13 derived current connecting circuits.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
