Abstract

The utility model discloses a kind of golden finger reverse side cut structure of backlight, described structure comprises backlight housing, the PCB be placed in backlight housing, described PCB is provided with row's LED, the circuit end of described LED is connected with golden finger, the both positive and negative polarity of golden finger is respectively arranged with the first via hole, the corner reverse side circuit that the both positive and negative polarity of described golden finger is connected with PCB circuit is also provided with the second via hole, and the contact gold thread passing hole road of described second via hole is communicated in the front-side circuit of PCB circuit.If after golden finger fractures, circuit not conducting, therefore, at circuit reverse side many increases by place via hole, after golden finger fractures, circuit reverse side also can flow into front circuit through the second via hole, final circuit or conducting.The electric current of reverse side pad runs into fracture to front through the first via hole locates not conducting, but reverse side electric current normally enters front-side circuit through the second via hole, and circuit finally can also conducting.

Description

A kind of golden finger reverse side cut structure of backlight
Technical field
The utility model relates to backlight field, relates to a kind of golden finger reverse side cut structure of backlight specifically.
Background technology
Quite universal in the application of electron trade printed circuit board (PCB) (PCB), the support plate as circuit is widely used in various electrical equipment.Along with the increase of device density and the increase of appliance power, the use of circuit board also gets more and more.
Please refer to the front-side circuit schematic diagram that accompanying drawing 1,3,5,7, Fig. 1 is traditional backlight source, Fig. 3 is the reverse side circuit diagram in traditional backlight source.Fig. 5 is the position schematic diagram of the easy fracture of traditional golden finger 2, and the tradition gold shown in figure refers to that the junction 21 of hand and circuit easily fractures, and after fractureing, front is with regard to not On current.Shown in Fig. 7, the electric current of reverse side pad also can not conducting to front through the first via hole 2011.Traditional golden finger 2 in front fractures, and just causes both sides not On currents, causes backlight point not work.
Utility model content
For deficiency of the prior art, the technical problems to be solved in the utility model there are provided a kind of golden finger reverse side cut structure of backlight.
For solving the problems of the technologies described above, the utility model is realized by following scheme: a kind of golden finger reverse side cut structure of backlight, described structure comprises backlight housing, be placed in the PCB in backlight housing, described PCB is provided with row's LED, the circuit end of described LED is connected with golden finger, the both positive and negative polarity of described golden finger is respectively arranged with the first via hole, the corner reverse side circuit that the both positive and negative polarity of described golden finger is connected with PCB circuit is also provided with the second via hole, the contact gold thread passing hole road of described second via hole is communicated in the front-side circuit of PCB circuit.
Further, the upper surface of described PCB circuit scribbles sub-light white oil.
Further, the corner cambered of the second via hole of described golden finger positive pole connection is between 110 ~ 120 degree.
Further, the corner cambered of the second via hole of described golden finger negative pole connection is between 160 ~ 175 degree.
Further, described second via hole is identical with the aperture of the first via hole.
Further, the aperture of described second via hole is between 0.5 ~ 1.5mm
Relative to prior art, the beneficial effects of the utility model are: if after golden finger fractures, circuit not conducting, therefore, at circuit reverse side many increases by place via hole, after golden finger fractures, circuit reverse side also can flow into front circuit through the second via hole, final circuit or conducting.The electric current of reverse side pad runs into fracture to front through the first via hole locates not conducting, but reverse side electric current normally enters front-side circuit through the second via hole, and circuit finally can also conducting.After pad solder element, can not occur Pad off phenomenon during bending, white oil uses sub-light white oil, by not there is jaundice or phenomenon of rupture after Reflow Soldering.

Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is explained in detail.
Please refer to accompanying drawing 2, 4, 6, 8, 9, 10, the golden finger reverse side cut structure of a kind of backlight of the present utility model, described structure comprises backlight housing 1, be placed in the PCB in backlight housing 1, described PCB is provided with row's LED 3, the circuit end of described LED 3 is connected with golden finger 201, the both positive and negative polarity of described golden finger 201 is respectively arranged with the first via hole 2011, the corner reverse side circuit that the both positive and negative polarity of described golden finger 201 is connected with PCB circuit is also provided with the second via hole 2012, the contact gold thread passing hole road of described second via hole 2012 is communicated in the front-side circuit of PCB circuit.The upper surface of described PCB circuit scribbles sub-light white oil 11, the corner cambered of the second via hole 2012 that described golden finger 201 positive pole connects is between 110 ~ 120 degree, the corner cambered of the second via hole 2012 that described golden finger 201 negative pole connects is between 160 ~ 175 degree, and described second via hole 2012 is identical with the aperture of the first via hole 2011.The aperture of described second via hole 2012 is between 0.5 ~ 1.5mm.
As shown in Fig. 6,8, after supposing that front golden finger 201 fractures, front-side circuit not conducting, reverse side many increases by second via hole 2012, if front golden finger fractures, reverse side also can flow into front circuit through the second via hole 2012, final circuit or conducting.The electric current of reverse side pad runs into fracture to front when the first via hole 2011 locates not conducting, but reverse side electric current normally enters front-side circuit through the second via hole 2012, and circuit finally can also conducting.
