Description

Technical Field

[0001] The present invention relates to a flexible LED strip with a shearable connecting conductor. Background Art

[0002] The existing flexible LED strip includes a flexible LED strip body, the flexible LED strip body includes a coating layer, a flexible circuit board arranged along the length direction of the coating layer in the coating layer, and a plurality of LEDs soldered on the flexible circuit board. The flexible circuit board includes a plurality of flexible circuit board units. In order to achieve a better lighting effect, it is often necessary to connect a plurality of flexible LED strips of different colors to each other. The connection method of two existing independent flexible LED strip bodies is as follows: on the flexible circuit board, a first shear position for shearing is provided between two adjacent flexible circuit board units, and a connecting conductor is arranged at the first shear position. Two ends of the connecting conductor are respectively fixed on two adjacent flexible circuit board units, and two ends of the connecting conductor are respectively electrically connected to the two adjacent flexible circuit board units. The connecting conductor is a hollow column, and a second shear position corresponding to the first shear position is arranged in the middle of the hollow column. During use, first, according to the length of the required flexible circuit board unit, shearing is performed at the first shear position and the second shear position. After shearing, the connecting conductor forms a hollow column with an end face that can be used for plugging. Then, a plurality of independent flexible LED strip bodies are arranged, and two ends of a pin are respectively inserted into the hollow columns of two adjacent flexible LED strip bodies to electrically connect the two flexible LED strip bodies. However, the above flexible LED strip structure has the following disadvantages: since the connecting conductor is a hollow column structure, when shearing, the second shear position is cut off under external force extrusion. After shearing, the end face of the plug-in part is easily deformed. The deformed hollow column is not convenient for plugging and is easily damaged, making it inconvenient to connect when the pin is inserted into the hollow column and more likely to affect the electrical connection effect. The electrical performance of the flexible LED strip is unstable. Summary of the Invention

The flexible LED light strip body 1 includes a coating layer 11, a plurality of flexible circuit board units 120 arranged along the length direction of the coating layer 11 within the coating layer 11, and a plurality of LEDs 13 soldered on the flexible circuit board units 120. A shearable position 123 for shearing is provided between two adjacent flexible circuit board units 120. A connection conductor 2 for connecting two adjacent flexible circuit board units 120 is further provided on the shearable position 123. Two ends of the connection conductor 2 are respectively fixed on two adjacent flexible circuit board units 120, and two ends of the connection conductor 2 are respectively electrically connected to the two adjacent flexible circuit board units 120. It is characterized in that: the connection conductor 2 includes two plug-in parts 23 for plugging and at least one conductor connection piece 24. The two plug-in parts 23 are respectively fixed on two adjacent flexible circuit board units 120 and are electrically connected to the two adjacent flexible circuit board units 120. The two plug-in parts 23 are connected by at least one conductor connection piece 24. The conductor connection piece 24 corresponds to the shearable position 123 and is shearable. Both of the plug-in parts 23 forming the connection conductor are in a hollow columnar shape. During production, the entire connection conductor 2 is soldered, which is convenient and time-saving. During use, only the shearable position 123 of the flexible circuit board 12 and the conductor connection piece 24 need to be sheared. The conductor connection piece 24 is relatively thin and is easy to shear, not easy to make mistakes, and will not deform the plug-in part 23 to cause damage; As Figure 2 shown, after shearing, the two plug-in parts 23 can be independently plugged, ensuring the electrical stability of the flexible LED light strip.

[0027] The above-mentioned conductor connection piece 24 and the plug-in part 23 it connects are integrally formed. It is convenient for production and has a low cost.

[0028] The above-mentioned plug-in part 23 is formed by bending a sheet-like body. The plug-in part 23 has elasticity, ensuring an elastic fit with the pin 3.

The welding parts 25 are convenient for welding and can ensure that the solder will not enter the hollow plug post during welding.

[0032] Each end of the above-mentioned flexible circuit board unit 120 has a positive electrical connection part 121 and a negative electrical connection part 122. The connecting conductor 2 includes a positive connecting conductor 21 and a negative connecting conductor 22. The two ends of the positive connecting conductor 21 are respectively connected to the positive electrical connection parts 121 of two adjacent flexible circuit board units 120, and the two ends of the negative connecting conductor 22 are respectively connected to the negative electrical connection parts 122 of two adjacent flexible circuit board units 120.

[0033] As Figure 3 shown, when it is necessary to connect two independent flexible LED strip bodies 1, the pin 3 can be used to connect the two flexible LED strip bodies 1. Specifically, the pin 3 is inserted into the corresponding positive connecting conductor 21 and the corresponding negative connecting conductor 22. The positive electrical connection parts 121 of the two flexible LED strip bodies 1 are electrically connected, and the negative electrical connection parts 122 of the two flexible LED strip bodies 1 are electrically connected. It is convenient to use.

[0034] Specifically, the connecting conductor 2 is fixed on the flexible circuit board unit by welding, and the plug connector 23 is electrically connected to the positive and negative poles of the flexible circuit board unit 120.

[0036] The flexible LED strip with a shearable connecting conductor provided in this embodiment is similar to the flexible LED strip with a shearable connecting conductor described in Embodiment 1, and the differences are as follows:

[0037] As Figure 5 shown, the number of the above-mentioned conductor connecting pieces 24 is two, and the two conductor connecting pieces 24 are respectively connected to the top and bottom of the edge of the insertion port of the two plug connectors 23.

[0038] As an alternative, for example, Figure 6 As shown, the two conductor connecting pieces 24 can also be respectively connected to the left and right sides of the edges of the insertion ports of the two connectors 23.

[0039] Embodiment 3:
