Description

Technical Field

[0001] The utility model relates to the technical field of flexible LED light strips, in particular to an unlimited shearable flexible light strip. Background Art

[0002] Due to the advantages of LEDs such as rich colors, small size, environmental protection and energy saving, and long life, they are made into LED light strips and are widely used in the lighting projects of the outlines of iconic buildings, towers, bridges, parks and squares, and have a wider range of applications in places such as home decoration, windows, signs, and billboards.

[0003] In actual applications, it is found that although many of the existing light strips on the market can be freely cut to the required length and then re-welded with a power source to achieve the power-on lighting function, in this welding process, auxiliary tools such as electric irons, spot welders or laser welders are required, and the use of auxiliary tools requires certain experience. Without relevant auxiliary tools or experience in the use of auxiliary tools, it is impossible to freely cut and reconnect the light strips, which is not practical and has obvious defects. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an unlimited shearable flexible light strip which can be electrically reconnected without requiring welding auxiliary tools under the premise of realizing free cutting.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: an unlimited and cuttable flexible light strip, an unlimited and cuttable flexible light strip, comprising a light strip base band and a light-transmitting protective cover wrapped around the outer surface of the light strip base band, the end of the light-transmitting protective cover is equipped with a plug cover corresponding to the cross-section of the light-transmitting protective cover, the number of the light strip base bands is two, the backs of the two light strip base bands are provided with power supply lines, the fronts of the two light strip base bands are provided with multiple LED lamp beads connected in parallel to the power supply lines, the backs of the two light strip base bands are arranged relative to each other, and the positive and negative polarities of the power supply lines on the same side are the same.

[0006] Preferably, the plug sleeve is provided with an insulating rubber core and an electrical terminal fixedly embedded in the insulating rubber core. The electrical terminal is inserted between the two light strip base bands and is in electrical contact with the power supply line.

[0007] Preferably, an insulating tensile reinforcement is provided between the two light strip base bands.

[0008] Preferably, one end of the plug sleeve is open, and the inner end of the plug sleeve is filled with a sealing gasket made of soft rubber material, which abuts and seals against the end face of the light-transmitting protective sleeve.

[0009] Preferably, a screw hole is provided on the outer end surface of the plug sleeve, and the plug sleeve is screwed to the light-transmitting protective sleeve after the screw passes through the screw hole.

[0010] Preferably, the cross-section of the light-transmitting protective cover is rectangular, elliptical, regular polygonal or circular.

[0011] The beneficial effect of the present invention is that the present invention provides an unlimited cuttable flexible light strip. In practical applications, the two light strip basebands can be easily electrically connected to the power supply end through the electrical connection terminal, thereby realizing the lighting function of the light strip baseband. When the light strip baseband needs to be cut, it can be directly cut at any position of the light strip baseband as needed. After cutting, the electrical connection terminal on the insulating rubber core is inserted into the gap between the two light strip basebands. The two light strip basebands are tightly attached to each other under the wrapping effect of the light-transmitting protective cover, and can ensure that the power supply line on the back of the light strip baseband maintains a good electrical connection relationship with the electrical connection terminal. Finally, the insulating rubber core, the light strip baseband and the end of the light strip protective cover are further reinforced and connected by the plug sleeve, and the conductive reliability is high. After the light strip baseband is cut, the electrical connection between the power supply line and the electrical connection terminal can be easily realized by plugging. The end package fixation can be easily and quickly realized without the help of any welding equipment or relying on welding work skills, which greatly simplifies the difficulty of the end package of the light strip baseband and is highly practical.

The electrical terminal 6 is inserted between the two light strip base bands 1 and is in electrical contact with the power supply line.

[0018] In actual application, the two light strip base bands 1 can be easily electrically connected to the power supply end through the electrical terminal 6 to realize the lighting function of the light strip base band 1. When the light strip base band 1 needs to be cut, it can be directly cut at any position of the light strip base band 1 as needed. After cutting, the electrical terminal 6 on the insulating rubber core 5 is inserted into the gap between the two light strip base bands 1. The two light strip base bands 1 are close to each other under the wrapping effect of the transparent protective cover 2, and can ensure that the power supply line on the back of the light strip base band 1 and the electrical terminal 6 maintain a good electrical connection. Finally, the end of the insulating rubber core 5, the light strip base band 1 and the transparent protective cover 2 are further reinforced and connected with the end of the plug cover 3, and the conductive reliability is high; after the light strip base band 1 is cut, the electrical connection between the power supply line and the electrical terminal 6 can be easily realized by plugging, without the help of any welding equipment, and without relying on welding work skills, the end packaging and fixation can be easily and quickly realized, which greatly simplifies the difficulty of the end packaging of the light strip base band 1 and is highly practical.
