Description
Technical field
The present invention relates to lighting area, more particularly to a kind of LED light strip.
Background technology
With the continuous improvement of people's living standards, the use of LED light strip is also increasingly popularized.In the prior art, it is soft
Property LED light strip include along light bar length direction extension clad, along light bar length direction extension flexible PCB and weldering
Some adopting surface mounted LEDs being connected on the flexible PCB, the clad is in sleeve-shaped by flexible circuit Slab element, patch type
LED chip coats, and the flexible PCB termination has electrical junction, at this time, to realize flexible LED rope light and power supply electricity
Connection is, it is necessary to connect an electric connector in the termination of light bar, as one kind of existing electric connector, such as CN 206059856
A kind of tail of LED power line shown in U is inserted, which inserts the cavity volume for including a receiving light bar, and the side of cavity volume, which is one, to detain
The head cover of conjunction, two sheet metal pins are used for being electrically connected with flexible PCB termination electrical junction as connection terminal, the metal
Piece pin is in cavity volume, and top cover inner surface, which is equipped with to what cavity volume protruded, to be used to clamp LED light strip to prevent the convex of LED light strip displacement
Tooth, the bottom that tail is inserted are equipped with two fins for being used to clamp LED light strip, and fin interest category under piece direction tail receptacle openings direction is prolonged
Stretch, when being inserted into cavity volume in light bar termination, touch flexible PCB termination electrical junction by two sheet metal pins, realization is electrically connected
Connecing, this fin and double wedge structure can firmly grasp light bar when head cover fastens to prevent the calm intracavitary of light bar from skidding off, and then
The purpose of fixed light band.
But often there is the phenomenon of poor electrical contact in actual use in said structure, traces it to its cause and is：(1) lamp
The clad of band is made of flexiplast, and fin and double wedge structure can firmly grasp light bar (clad) when head cover fastens
To prevent the calm intracavitary of light bar from skidding off, achieve the purpose that fixed light band, but cannot prevent light bar (clad) deformation, cause flexibility
Circuit board termination electrical junction is opposite cannot to be contacted with the displacement of sheet metal pin；(2) flexible PCB termination is also flexibility,
Its by clad extruding also can deformation, cause flexible PCB termination electrical junction opposite with the displacement of sheet metal pin and cannot
Contact；(3) coefficient of thermal expansion and contraction of flexible PCB and clad is different, said structure secure clad can not fix it is soft
Property circuit board, realize the opposite steady contact with sheet metal pin in flexible PCB termination electrical junction；(4) light bar has flexible
Property, when using bending, it will also result in the relative displacement of flexible PCB and clad.
Moreover according to above-mentioned mentality of designing, when adopting surface mounted LED 4 is divided into red, blue, green three groups on flexible PCB 13
LED illumination circuit, the power supply of each group LED illumination circuit are born incoming end and are electrically connected respectively in the termination of flexible PCB
Portion, plus the electrical junction of a positive incoming end of power supply, at least needs to arrange 4 electrical junctions in circuit board termination.By
Influenced in the width of circuit board by 4 ratio of adopting surface mounted LED, the width of circuit board should as close possible to 4 size of adopting surface mounted LED,
And adopting surface mounted LED 4 has all accomplished less than 5 millimeters of width, therefore width of circuit board also requires closely possibility small.But 4 connections
Portion and when being listed in the termination of circuit board, its spacing becomes very small, for the light bar for connecting alternating current, it is difficult to which meeting safety will
Ask, and since circuit board is flexible, when inserting the sheet metal of (electric connector) with tail for connecing, easy wrong, to power for illumination
Component on road causes damage, and improves the design cost of the anti-wrong of lighting circuit in other words.
