Description

柔性LED灯带Flexible LED strip

本申请是申请号为201810147886.0,发明名称为“柔性LED灯带”的中国专利申请的分案申请。This application is a divisional application of a Chinese patent application with an application number of 201810147886.0 and an invention name of "flexible LED light strip".

技术领域technical field

本发明涉及照明领域,尤其涉及一种LED灯带。The invention relates to the field of lighting, in particular to an LED light strip.

背景技术Background technique

随着人们生活水平的不断提高,LED灯带的使用也越来越普及。在现有技术中,柔性LED灯带包括沿灯带长度方向延伸的包覆层、沿灯带长度方向延伸的柔性电路板以及焊接在所述柔性电路板上的若干贴片式LED,所述包覆层呈套筒状将柔性电路板单元、贴片式LED芯片包覆,所述的柔性电路板端头具有电性连接部,此时,为实现柔性LED灯带与电源电连接,需要在灯带的端头接上一个电连接器,作为现有的电连接器的一种,如CN206059856U所示的一种LED电源线的尾插,该尾插包括一个容纳灯带的容腔,容腔的一侧是一个可扣合的顶盖,两个金属片针作为连接端子用来与柔性电路板端头电性连接部电连接,该金属片针处在容腔内,顶盖内表面设有向容腔凸出的用于夹紧LED灯带以防止LED灯带位移的凸齿,尾插的底部设有两条用于夹紧LED灯带的凸棱,凸棱子金属片下方向尾插座开口方向延伸,在灯带端头插入容腔时,依靠两个金属片针触及柔性电路板端头电性连接部,实现电连接,这种凸棱和凸齿结构在顶盖扣合时可以抓紧灯带以防止灯带从容腔内滑出,进而达到固定灯带的目的。With the continuous improvement of people's living standards, the use of LED strips has become more and more popular. In the prior art, a flexible LED light strip includes a cladding layer extending along the length of the light strip, a flexible circuit board extending along the length of the light strip, and a number of SMD LEDs soldered on the flexible circuit board. The covering layer is sleeve-shaped to cover the flexible circuit board unit and the SMD LED chip, and the end of the flexible circuit board has an electrical connection part. An electrical connector is connected to the end of the light strip, as one of the existing electrical connectors, such as a tail plug of an LED power cord shown in CN206059856U, the tail plug includes a cavity for accommodating the light strip, One side of the cavity is a top cover that can be snapped together, and two metal sheet pins are used as connection terminals to electrically connect with the electrical connection part of the end of the flexible circuit board. The metal sheet pins are located in the cavity and inside the top cover The surface is provided with convex teeth protruding toward the cavity for clamping the LED light strip to prevent the LED light strip from being displaced. The bottom of the tail plug is provided with two convex edges for clamping the LED light strip. The convex edge is a metal sheet. The bottom extends toward the opening of the tail socket. When the end of the light strip is inserted into the cavity, the electrical connection is realized by touching the electrical connection part of the end of the flexible circuit board with two metal sheet pins. When buckled, the light strip can be grasped to prevent the light strip from slipping out of the cavity, so as to achieve the purpose of fixing the light strip.

但是,上述结构在实际使用中常出现电性接触不良的现象,究其原因在于:(1)灯带的包覆层是采用柔性塑料制作的,凸棱和凸齿结构在顶盖扣合时可以抓紧灯带(包覆层)以防止灯带从容腔内滑出,达到固定灯带的目的,但不能防止灯带(包覆层)形变,导致柔性电路板端头电性连接部相对与金属片针位移而不能接触;(2)柔性电路板端头也是柔性的,其受包覆层的挤压也会形变,导致柔性电路板端头电性连接部相对与金属片针位移而不能接触;(3)柔性电路板和包覆层的热胀冷缩系数不同,上述结构固定了包覆层并不能固定柔性电路板,实现柔性电路板端头电性连接部相对与金属片针的稳定接触;(4)灯带具有可挠性,在使用弯曲时,也会造成柔性电路板与包覆层的相对位移。However, the above structure often has poor electrical contact in actual use. The reason is: (1) The coating layer of the light strip is made of flexible plastic, and the convex ridge and convex tooth structure can be used when the top cover is buckled. Grasp the light strip (cladding layer) to prevent the light strip from sliding out of the cavity to achieve the purpose of fixing the light strip, but it cannot prevent the deformation of the light strip (cladding layer), resulting in the electrical connection part of the end of the flexible circuit board being opposite to the metal (2) The end of the flexible circuit board is also flexible, and it is also deformed by the extrusion of the coating layer, which causes the electrical connection part of the end of the flexible circuit board to be displaced relative to the metal sheet needle and cannot be contacted (3) The thermal expansion and cold contraction coefficients of the flexible circuit board and the cladding layer are different. The above structure fixes the cladding layer and cannot fix the flexible circuit board, so as to realize the stability of the electrical connection part of the end of the flexible circuit board relative to the metal sheet needle. (4) The light strip is flexible, and it will also cause relative displacement between the flexible circuit board and the cladding layer when it is bent.

After slotting, a snap-type tightening strap 214 can be used to fasten the light strip to the outer slot through the fixing ring 213 and along the stepped portion 212 .

由于包覆层是可挠性的塑料,一般具有弹性,腔体可做弹性的扩张,上述的柔性LED灯带,内插槽的外壁尺寸可以小于或等于或略大于包覆层内腔尺寸,当内插槽的外壁尺寸等于或略大于包覆层内腔尺寸,内插槽的这种外壁尺寸有利于使包覆层夹紧内插槽,使内插槽进一步夹紧柔性电路板,同时达到固定的包覆层的目的。Since the cladding layer is a flexible plastic, it is generally elastic, and the cavity can be elastically expanded. In the above-mentioned flexible LED light strip, the outer wall size of the inner slot can be smaller than or equal to or slightly larger than the inner cavity size of the cladding layer. When the size of the outer wall of the inner slot is equal to or slightly larger than the size of the inner cavity of the cladding layer, the outer wall size of the inner slot is favorable for the cladding layer to clamp the inner slot, so that the inner slot further clamps the flexible circuit board, and at the same time To achieve the purpose of a fixed coating.
