Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting fixtures, and more specifically, to a flexible light strip that can be cut to any size. Background Technology
[0002] The emergence of flexible light strip products has led to a wide variety of lighting products. Current flexible light strips can be bent and combined into various patterns or texts due to their flexibility. They are generally powered by conductive plugs that pass through the light strip and are inserted into the internal circuit board.
[0003] Because the patterns of flexible LED strips are designed by users, they are all cut to fit together. However, the cut LED strips need to be electrically connected. This is done by removing the flexible outer shell covering the positive and negative electrodes on the flexible circuit board and then soldering wires to the positive and negative electrodes to connect to the external power source. This is very inconvenient. Utility Model Content
[0004] To address the aforementioned shortcomings of existing technologies, a flexible light strip that can be cut to any size is provided.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a flexible light strip that can be cut at will, comprising a flexible circuit board and a plurality of light beads thereon. The plurality of light beads are arranged at equal intervals along the extension direction of the flexible circuit on the flexible circuit board. A positive electrode and a negative electrode are provided between two adjacent light beads on the flexible circuit board. A flexible shell is provided on the flexible circuit board to cover the flexible circuit board and the light beads. An insertion cavity is provided inside the flexible shell. The positive electrode and the negative electrode are both located in the insertion cavity. A contact block electrically connected to an external power source is provided at one end of the flexible shell. A groove is provided on the contact block for inserting the flexible shell. A clamping plate is provided in the groove for holding the flexible shell. A driving mechanism for driving the clamping plate to move is provided on the contact block. A contact electrode is provided on the contact block to insert into the insertion cavity and electrically connected to the positive electrode and the negative electrode.
[0006] Preferably, the driving mechanism includes a lead screw, which is rotatably disposed in a groove and located near the bottom of the groove. The clamping plate is threadedly connected to the lead screw, and one end of the lead screw extends out of the electrical contact block.
[0007] Preferably, a knob is provided at one end of the lead screw that extends out of the electrical contact block.
[0008] Preferably, a limiting rod is provided in the groove near the bottom of the groove, the limiting rod is spaced apart from the lead screw, and the clamping plate is sleeved on the limiting rod.
[0009] Preferably, the positive and negative electrodes are arranged on opposite sides of the line connecting two adjacent LED beads, two insertion cavities are provided, and the two insertion cavities pass through multiple positive and multiple negative electrodes respectively. Two power-connecting electrodes are provided, and the two power-connecting electrodes are inserted into the two insertion cavities respectively.
[0010] Preferably, the clamp is provided with a first anti-slip tooth, and the groove is provided with a second anti-slip tooth on the surface opposite to the first anti-slip tooth.
[0011] Preferably, the flexible housing has cutting marks on its outer surface facing away from the LED bead.
[0012] Preferably, the contact block is provided with wires that are electrically connected to the contact electrodes.
[0013] The beneficial effects of this utility model are as follows: After the light strip is cut to the required length, it is inserted into the groove of the flexible shell. At this time, the electrode is inserted into the insertion cavity and electrically connected to the positive and negative electrodes. Then, the clamping plate is driven by the driving mechanism to move, so that the clamping plate cooperates with the inner wall of the groove to clamp the light strip, thereby fixing the electrode block on the light strip, thus completing the conductive connection of the light strip. It is not necessary to remove the flexible shell covering the flexible circuit board, nor is it necessary to solder wires, which is very convenient. Attached Figure Description
