Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Fig. 1 is a schematic structural diagram of the present invention, which includes a shorting tab main body 10 and at least three pins disposed on one side of the shorting tab main body 10; the pins comprise an electric connection pin 11 and an auxiliary pin 12; pins at two ends of the short contact piece main body 10 are electric connection pins 11 for being electrically connected with the PCB substrate 1, and the rest are auxiliary pins 12 for supporting and fixing the short contact piece main body 10; when the large current routing distance is short, those skilled in the art can reduce the length of the shorting tab body 10 by cutting and reduce the number of pins.

First embodiment

In the present embodiment, for clarity of illustration of the technical solution of the present invention, the PCB large current routing shorting tab has three pins, including two electrical connection pins 11 located at two ends of the shorting tab main body 10 and one auxiliary pin 12 located at the middle section of the shorting tab main body 10; in other embodiments, the PCB high current routing shorting tab may have more pins, the present invention does not limit the maximum number of pins.

Fig. 2 shows a comparison of the three-dimensional trace of the present embodiment with a conventional copper-clad trace 2. When a large current is routed in a traditional copper plating mode, under the condition that the space between welding holes 3 of a device is determined, the cross section area of a copper plating routing 2 needs to be increased in a mode of widening the width or increasing the thickness, so that the resistance of the copper plating routing is reduced. Since the copper-clad traces 2 on the PCB substrate 1 are mainly disposed by electroplating, the cost of increasing the thickness thereof is high.

The short tab main body 10 of the present embodiment is a copper strip manufactured by stamping, so that the cost for increasing the width and thickness is low. When the cross-sectional area of the shorting tab body 10 is larger than that of the copper-clad trace 2, the resistance of the shorting tab body is smaller than that of the copper-clad trace 2 with the same length, so that the heat generated when a large current passes through the shorting tab body can be reduced. On the other hand, since the shorting tab main body 10 is erected on the PCB substrate 1, both sides of the shorting tab main body 10 are exposed to the air, which is more advantageous for heat dissipation to the air.

The shorting tab body 10 of this embodiment has two bends, and the linear pitch of the actual traces is shorter than the total length of the shorting tab body 10. The technical personnel in the field can set up the figure, position and the angle of bending as required to make the PCB heavy current of the same length walk line short-circuit piece and adapt to the needs of different line straight-line distances, walk around other devices on PCB base plate 1 when walking the line simultaneously. When the difference between the linear distance of the trace and the total length of the short tab main body 10 is greater than the distance between the adjacent pins of the PCB high-current trace short tab, a person skilled in the art can cut off the short tab main body 10 at one side of the auxiliary pin 12, at this time, the PCB high-current trace short tab becomes a short tab with two pins, at this time, the two pins are both electrically connected with the pin 11, and the length of the short tab main body 10 is correspondingly shortened.

Fig. 3 shows the installation of the present embodiment. When the PCB large-current trace short tab of the present embodiment is mounted on the PCB substrate 1, the PCB substrate 1 is pre-provided with an electrical connection solder hole 21 corresponding to the electrical connection pin 11 and an auxiliary solder hole 22 corresponding to the auxiliary pin 12. The electric connection welding hole 21 is electrically connected with the device welding hole 3 through a short-circuit piece electric connection copper-clad layer 9; the auxiliary solder apertures 22 do not require electrical connections. During installation, after the short tab main body 10 is bent into a corresponding shape, the electric connection pins 11 and the auxiliary pins 12 are respectively inserted into the electric connection welding holes 21 and the auxiliary welding holes 22 and welded, and then large-current three-dimensional routing between two different device welding holes 3 can be achieved.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
