Description

Technical Field

[0001] The present invention relates to a flexible wire array and an LED light strip to which the same is applied. Background Art

[0002] The existing flexible LED light strip includes: a strip-shaped wire array, a flexible circuit board, and a light-transmitting coating layer. The coating layer extends along the length direction of the light strip to cover the wire array and the flexible circuit board. The wire array includes two or more flat wires arranged side by side at intervals, and each flat wire extends along the length direction of the wire array. Each flat wire extends along the length direction of the wire array and is fixed to an insulating film side by side at intervals. The flexible circuit board includes a plurality of flexible circuit board units arranged at intervals. The flexible circuit board units are arranged along the length direction of the wire array, and there is a gap between two adjacent flexible circuit board units. An LED element is welded on the front surface of each flexible circuit board unit. The back surface of each flexible circuit board unit faces the wire array. Each flexible circuit board unit is provided with at least a pair of positive and negative electrode solder joints. An insulating film is provided between the flexible circuit board and the wire array. The insulating film is in surface contact with each flat wire. The insulating film includes more than two strip-shaped film units. The strip-shaped film units are distributed at intervals along the length direction of the wire array. The flat wire is exposed in the gap area between adjacent strip-shaped film units to form a flat wire connection area. The positive and negative electrode solder joints of each flexible circuit board unit are welded to the flat wire. For the flexible LED light strip with this structure, each flexible circuit board, wire array, and coating layer will not produce wrinkles, and there will be no relative wrinkles or relative de-soldering between the flexible circuit board and the wire array due to the continuous bending and stretching of the light strip. When the light strip is in use, the user can cut it along the gap between two flexible circuit board units according to the required length of the LED light strip. The positive and negative electrode solder joints are used not only for electrical connection with the wire array but also for electrical connection between the flexible LED light strip and external electrical components. However, for the LED light strip with this structure, the flat wire in the gap area is easily broken, and the connection between the positive and negative electrode solder joints and external electrical components is troublesome and unstable.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the protection scope of the present invention.

[0035] Embodiment 1:

[0036] As Figures 1 to 3 shown, what this embodiment provides is a flexible wire array, including at least two flat wires 12 and an insulating film 11. Each flat wire 12 is fixedly arranged side by side at intervals on one side of the insulating film 11. It is characterized in that: a plurality of hollow areas 114 are arranged at intervals along the length direction of the flat wire 12 on the insulating film 11. Each hollow area 114 is provided with a plurality of hollow holes 111 at the position corresponding to the flat wire 12. Each hollow hole 111 is arranged along the width direction of the insulating film 11. The exposed parts of each flat wire 12 in the hollow holes 111 form a flat wire connection area 121. A connection conductor 13 is fixed on the flat wire connection area 121. The connection conductor 13 includes two plug-in parts 131 for plugging and at least one conductor connection piece 132. The two plug-in parts 131 are respectively fixed on the same flat wire 12 and are electrically connected to the flat wire 12. The two plug-in parts 131 are connected by at least one conductor connection piece 132. Both of the plug-in parts 131 forming the connection conductor 13 are in a hollow column shape. The flexible wire array has a simple structure. The connection conductor 13 strengthens the flat wire 12 in the flat wire connection area 121, preventing the flat wire 12 from breaking. When in use, only need to cut the insulating film 11, the flat wire 12, and the conductor connection piece 132 along the hollow area 114. After cutting, a hollow column that can be plugged is formed at the end of the flexible wire array, facilitating the electrical connection between the flexible wire array and external electrical components.

[0037] The above-mentioned connection conductor 13 is fixed on the flat wire connection area 121 by welding. The insulating film 11 and the connection conductor 13 are respectively arranged on the upper and lower sides of the flat wire 12.

[0038] The above-mentioned conductor connection piece 132 is integrally formed with the plug-in part 131 it connects. The production of the connection conductor 13 is convenient and the yield is high.

[0039] The above-mentioned conductor connection piece 132 has a bending arc. The conductor connection piece 132 and the two plug-in parts 131 are integrally bent from a sheet-like body. It can ensure that the two plug-in parts 131 have a certain elasticity, making the electrical connection between the plug-in parts 131 and external electrical components more stable.

[0040] The number of the above-mentioned conductor connecting pieces 132 is one, and the conductor connecting piece 132 is connected to the top or bottom of the mouth edges of the insertion interfaces of two plug connectors 131. When shearing, the plug connectors 131 are not easily deformed or damaged, making the insertion of the plug connectors 131 more convenient.

It is characterized in that: the insulating film includes a plurality of block-shaped film units 112. Each block-shaped film unit 112 is arranged along the length direction of the flat wire 12 and is distributed at intervals. A gap 113 is provided between two adjacent block-shaped film units 112. The exposed parts of each flat wire 12 in the gap 113 form flat wire connection areas 121. Connection conductors 13 are welded on the flat wire connection areas 121. The connection conductor 13 includes two plug connectors 131 for insertion and at least one conductor connecting piece 132. The two plug connectors 131 are respectively fixed on the same flat wire 12 and are electrically connected to the flat wire 12. The two plug connectors 131 are connected by at least one conductor connecting piece 132. Both of the plug connectors 131 constituting the connection conductor 13 are in a hollow columnar shape. The production and shearing of the flexible wire array are more convenient.

[0048] As Figure 6 shown, the flexible wire array provided in this embodiment is similar to the flexible wire array described in Embodiment 1 or Embodiment 2 or Embodiment 3, except that:

[0049] The connection conductor 13 and the insulating film 11 are both arranged on the upper side of the flat wire 12.

The flexible wire array 1 and the flexible circuit board 2 are installed in the coating layer 3. A plurality of LED elements 21 are soldered on the front surface of the flexible circuit board 2. The flexible wire array 1 is arranged on the back surface of the flexible circuit board 2. At least a pair of positive and negative solder joints 24 are provided on the flexible circuit board 2. It is characterized in that: the flexible wire array 1 is the flexible wire array described in Embodiment 1, Embodiment 2 or Embodiment 3, and the positive and negative solder joints 24 are respectively soldered to different flat wires 12.

[0052] By improving the structure of the flexible wire array, the connection conductor 13 reinforces the flexible wire array 1, increases the overall strength of the LED strip, avoids easy breakage when the LED strip is twisted, and makes the performance of the LED strip more stable; after shearing, the plug-in connector 131 is used to electrically connect with external electrical components, and the connection is more convenient and fast.
