Accompanying drawing explanation

Below in conjunction with accompanying drawing, the detailed description of the invention of the present invention is described in further detail, wherein:

Fig. 1 is the structural representation of the flexible LED rope light in the present invention.

Detailed description of the invention

As it is shown in figure 1, flexible LED rope light, including light bar body 2 and the attaching plug 1 that is connected with light bar body 2, power supply Plug 1 includes two housings mutually covered 4 first insulation fixed body 5 of being connected fixing with housing 4 and is fixed on the first insulation Two conductive pins 6 on fixed body 5, are arranged to two housings mutually covered 4 so that the dismounting of attaching plug 1 and assembling are more Adding simple, conductive pin 6 is by being fixed on the first insulation fixed body 5 being connected fixing with housing 4, thus realizes entering with housing 4 Row is fixing to be connected, LED operationally, by the conductive pin 6 on attaching plug 1 is carried out grafting with supply socket, it is achieved The connection of circuit, is connected fixing for conductive pin 6 and housing 4 so that conductive pin 6 with the plug of supply socket during, Do not have the situation making the connection instability of conductive pin 6 and circuit board 7 even be short-circuited because of loosening, attaching plug Be additionally provided with circuit board 7 in 1, circuit board 7 be provided with commutator 71 and some pads 14, two conductive pins 6 respectively with circuit Plate 7 is welded by pad 14, and the first insulation fixed body 5 vertically protrudes out protruding 15 on the end face of circuit board 7, circuit Being provided with on plate 7 and protruding 15 recesses 16 matched, circuit board 7 is welded with also by pad 14 and is connected with light bar body 2 Contact pin 8, conductive pin 6 and contact pin 8 are separately positioned on the two ends of circuit board 7, by the circuit board 7 conduction directly and on attaching plug 1 Pin 6 welds, so that circuit board 7 directly achieves a fixed connection with attaching plug 1, so that the structure of LED Simpler, attaching plug 1 is more stable, firm with the connection of circuit board 7, and due to LED generally practicality is unidirectional current Source, arranges commutator 71 on circuit board 7, can be the most permissible by being converted to DC current by the alternating current of conductive pin 6 The work that LED can be stable, the projection 15 on the first insulation fixed body 5 are matched with the recess 16 on circuit board 7, During so that conductive pin 6 welds with circuit board 7 again, it is possible to circuit board 7 is carried out stable location, so that circuit board Welding between 7 and conductive pin 6 is convenient, accurate.

Contact pin 8 can be provided with two, and one connects positive pole, and one connects negative pole, so so that alternating current passes through After commutator 71 is converted to unidirectional current, in positive pole flows into light bar body 2, then flow back at supply socket through negative pole, structure Becoming current loop, contact pin 8 is fixedly connected on the second insulation fixed body 9, and contact pin 8 is by being arranged on inserting of light bar body 2 end Hole 10 and light bar body 2 carry out grafting, and light bar body 2 and contact pin 8 carry out grafting, so that wire 3 and the company of light bar body 2 Connect more firm, and can at any time light bar body 2 be dismantled, carry out different light bar body 2 according to different demands Change, easy to connect, quick, contact pin 8 is fixed on the second insulation fixed body 9, the position of two contact pins 8 can be carried out solid Fixed, it is to avoid contact pin 8 is when carrying out plug with jack 10, and contact pin 8 position is not fixed, cause two contact pins 8 can not simultaneously with jack 10 Carry out grafting so that attaching plug 1 becomes difficulty with the connection of light bar body 2, unstable.

Light bar body 2 can include the FPC soft board 11 in strip and the LED chip 12 being arranged on FPC soft board 11, will LED chip 12 is arranged on FPC soft board 11, and light bar body 2 can be made to realize bending and reverse, such that it is able to by light bar body 2 It is arranged to various different shape, facilitates the placement of light bar body 2 simultaneously, and the circuit on FPC soft board 11 will not be made to occur The situation of open circuit so that LED chip 12 can be normal luminous, and the dead ahead of the light emission direction of LED chip 12 is provided with lens 13, Such setting, so that the point source that LED chip 12 sends carries out dissipating penetrating after the refraction of lens 13 again, makes LED The light range of exposures that chip 12 sends is bigger, and user will not cause the untoward reaction such as dazzling and dazzle simultaneously.

Housing 4 and the second insulation fixed body 9 can be made up of polythene material, and polythene material electrical insulation capability is excellent, While conductive pin 6 and contact pin 8 are fixed, moreover it is possible to play good insulating effect, it is to avoid conductive pin 6 and contact pin 8 Contacting with other hardwares, cause situation short circuit occur, polythene material has good toughness, can be greatly improved shell Body 4 and the life-span of the second insulation fixed body 9, conductive pin 6 and contact pin 8 can be made up of stainless steel material, are so possible to prevent to lead In use for some time, there is the situation that the electric conductivity getting rusty and making conductive pin 6 and contact pin 8 is deteriorated in acusector 6 and contact pin 8, Meanwhile, stainless hardness is higher, when contact pin 8 and jack 10 carry out grafting, it is not easy to abrasion, it is to avoid contact pin 8 becomes because of abrasion After little, with the light bar body 2 unstable situation of grafting.

The end of conductive pin 6 and contact pin 8 can be in round table-like setting, and conductive pin 6 is concordant with the end of contact pin 8, does not set It is equipped with guiding position, it has not been convenient to conductive pin 6 and contact pin 8 carry out grafting with supply socket and light bar body 2 respectively, and can make to lead Acusector 6 is deteriorated with the electric conductivity of contact pin 8, and the end of conductive pin 6 and contact pin 8 arranges point and easily hurts sb.'s feelings, round table-like end The effect of guiding can be played with supply socket and light bar body 2 respectively at conductive pin 6 and contact pin 8 by portion when carrying out grafting, it is simple to Grafting, and round table-like end is more mellow and fuller, and the phenomenon of scathing will not occur.

Lens 13 can be made up of sapphire material, the lens 13 using sapphire material to make, and has good printing opacity Property, this allows for point source that LED chip 12 sends after the refraction of sapphire lens 13, decreases the loss of energy, make The light that sends of LED bulb is brighter, and the feature such as sapphire has wear-resisting, high temperature resistant, owing to lens 13 are arranged on LED chip The dead ahead of 12, when LED chip 12 is luminous, can use the lens 13 that sapphire material is made, no along with the generation of high temperature Can deform because of high temperature, improve the service life of lens 13.

Silica gel can be coated with on FPC soft board 11 in strip, FPC soft board 11 is coated with silica gel, its main purpose It is so that lens 13 can be stably fixed to the surface of the light emission direction of LED chip 12, so that lens 13 reach right The refraction action of the point source that LED chip 12 sends, can be provided with fluorescent material, add the mesh of fluorescent material in silica gel in silica gel Be so that the light-source brightness after entering superrefraction is higher, owing to high temperature, circuit board can be produced after LED chip 12 continuous illumination The silica gel on 7 surfaces can also play good cooling effect, so that the life-span of circuit board 7 is improved.

Above example is only in order to illustrate that technical scheme is not limited, all without departing from the present invention Any amendment of spirit and scope or equivalent, it all should be contained in the range of technical solution of the present invention.
