Abstract
Description
Technical Field
[0001] This application relates to the technical field of light strips, and in particular to a light strip with a protective end. Background Technology
[0002] In daily life, LED strip lights are often used for decoration. LED strip lights are made by soldering LED lights onto copper wires or flexible circuit boards using special processing techniques, and then connecting them to a power source to emit light. They are named for their shape resembling a strip of light when they are lit.
[0003] In existing technology, LED strips are connected to conductive wires, which are then connected to an external power source to enable the strips to emit light. However, it has been found that these LED strips are frequently damaged during use due to accidental pulling on the strips or conductive wires. This often results in cracks or even breakage at the connection point between the strip and the wires caused by tension or repeated bending. This not only reduces the lifespan of the LED strips but also poses certain safety hazards, thus requiring further improvement. Utility Model Content
[0004] To improve the structural stability of the connection between the light strip and the conductive wire, this application provides a light strip with a protective end.
[0005] The light strip with a protective end provided in this application adopts the following technical solution:
[0006] A light strip with a protective end includes a light strip body, a conductive wire, and a protective end. One end of the protective end has a protective channel, which includes a main channel and a secondary channel that are interconnected. One end of the light strip body extends into the main channel and is connected to one end of the conductive wire. The end of the conductive wire away from the light strip body exits through the secondary channel.
[0007] By adopting the above technical solution, when installing the protective end, the connection between the light strip body and the conductive wire is folded in half, and then inserted into the protective channel of the protective end and connected and fixed, so that the light strip body passes through the main channel and the conductive wire passes through the secondary channel; the protective end can strengthen the protection of the connection between the light strip body and the conductive wire, improve the structural stability of the connection between the light strip body and the conductive wire, and thus improve the overall service life.
[0008] Optionally, the main body of the light strip includes a light-emitting body, a first protective layer, and a second protective layer. The first protective layer is wrapped around the light-emitting body, and the second protective layer is wrapped around the first protective layer. The second protective layer is an anti-ultraviolet layer.
[0009] By adopting the above technical solution, the first protective layer and the second protective layer can provide good protection for the light-emitting lamp body. The second protective layer is set as an anti-ultraviolet layer, which improves the overall structure's anti-aging performance and extends the lifespan of the light-emitting lamp body.
[0010] Optionally, the protective channel is filled with an adhesive layer, and an end cap is provided at the opening of the protective channel. The surface of the end cap has a passage for the light strip body and conductive wire to pass through.
[0011] By adopting the above technical solution, after the light strip body and the conductive wire are inserted into the protective channel, adhesive is filled into the protective channel. After the adhesive solidifies, an adhesive layer is formed, thereby connecting the protective end with the light strip body and the protective end with the conductive wire as one unit.
[0012] Optionally, the outer wall of the end cap is provided with a mating ring, which is elastically set, and the inner wall of the opening of the protective channel is provided with a mating groove for the mating ring to be inserted.
[0013] By adopting the above technical solution, when installing the end cap, align the end cap with the opening of the protective channel and push it so that the mating ring is squeezed into the mating groove of the protective channel, thereby improving the ease of connection between the end cap and the protective end.
[0014] Optionally, the end cap has a plurality of extrusion blocks embedded in the adhesive layer on the surface near the protective channel.
[0015] By employing the above technical solution, after injecting adhesive into the protective channel, the end cap is placed over the opening of the protective channel. The extrusion block of the end cap can compress the adhesive, making the adhesive layer more dense after solidification. Furthermore, after the adhesive solidifies and forms an adhesive layer, it wraps around the extrusion block, connecting the protective end, end cap, light strip body, and conductive wire into a single unit, greatly improving the overall structural stability.
[0016] Optionally, the through-hole includes a first through-hole and a second through-hole that are interconnected. The main body of the light strip passes through the first through-hole, and the conductive wire passes through the second through-hole. A sealing block is provided at the connection between the first through-hole and the second through-hole. The sealing block is elastically set, and its two sides abut against the outer peripheral wall of the main body of the light strip and the outer peripheral wall of the conductive wire, respectively.
[0017] By adopting the above technical solution, when the end cap seals the opening of the protective channel, the two sides of the sealing block abut against the outer peripheral wall of the light strip body and the outer peripheral wall of the conductive wire, respectively, so as to reduce the gap of the penetration channel and reduce the possibility of the adhesive in the protective channel being squeezed out along the penetration channel.
[0018] Optionally, the end cap has a connector on its surface near the protective channel, and an adhesive layer is wrapped around the connector.
[0019] By adopting the above technical solution and setting the plug-in piece, the bonding stability between the adhesive layer and the end cap is further improved.
[0020] Optionally, the side wall of the plug-in piece away from the end cover is provided with a deformation groove, which divides the plug-in piece into a first abutting part and a second abutting part; the inner wall of the protective channel is provided with a support rod, which is inserted into the deformation groove when the end cover closes the opening of the protective channel, and forces the first abutting part to abut against the surface of the light strip body and the second abutting part to abut against the surface of the conductive wire.
[0021] By adopting the above technical solution, when the end cap seals the opening of the protective channel, the support rod is inserted into the deformation groove, thereby squeezing open the first abutting part and the second abutting part, forcing the first abutting part to abut against the surface of the light strip body and the second abutting part to abut against the surface of the conductive wire, thereby improving the connection stability between the light strip body and the protective end, and between the conductive wire and the protective end.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. By setting up a protective end, when installing the protective end, fold the connection between the light strip body and the conductive wire, then insert it into the protective channel of the protective end and connect and fix it, so that the light strip body passes through the main channel and the conductive wire passes through the secondary channel; the protective end can strengthen the protection of the connection between the light strip body and the conductive wire, improve the structural stability of the connection between the light strip body and the conductive wire, and thus improve the overall service life;
[0024] 2. By setting the extrusion block, after injecting adhesive into the protective channel, the end cap is closed on the opening of the protective channel. The extrusion block of the end cap can squeeze the adhesive, making the adhesive layer after the adhesive solidifies more dense.
[0025] 3. By using the plug-in piece and the support rod, when the end cap blocks the opening of the protective channel, the support rod is inserted into the deformation groove, thereby squeezing open the first abutting part and the second abutting part, forcing the first abutting part to abut against the surface of the light strip body and the second abutting part to abut against the surface of the conductive wire, thereby improving the connection stability between the light strip body and the protective end, and between the conductive wire and the protective end.

Detailed Implementation
[0034] The following combination Figures 1-7 This application will be described in further detail.
[0035] Example 1: This application discloses a light strip with a protective end.
[0036] Reference Figure 1 , Figure 2 A light strip with a protective end includes a light strip body 1, a conductive wire 2, and a protective end 3. The light strip body 1 includes a light-emitting body 11, a first protective layer 12, and a second protective layer 13. The first protective layer 12 is wrapped around the outer peripheral wall of the light-emitting body 11, and the second protective layer 13 is wrapped around the outer peripheral wall of the first protective layer 12. In this embodiment, the first protective layer 12 can be a silicone sleeve to buffer external impact, and the second protective layer 13 can be an anti-ultraviolet layer made of fluorosilicone rubber to improve anti-ultraviolet performance and slow down aging.
[0037] Reference Figure 3 , Figure 4 One end of the protective end 3 is provided with a protective channel 31. The protective channel 31 includes a main channel 32 and two secondary channels 33. The two secondary channels 33 are symmetrically distributed on both sides of the main channel 32. Both secondary channels 33 are connected to the main channel 32. One end of the light strip body 1 extends into the main channel 32 and is connected to one end of the conductive wire 2. The end of the conductive wire 2 away from the light strip body 1 passes through the secondary channel 33.
[0038] The protective channel 31 is filled with adhesive, which can be PU adhesive. After the adhesive solidifies, it forms an adhesive layer 34.
[0039] The implementation principle of Embodiment 1 of this application is as follows: When installing the protective end 3, the connection between the LED strip body 1 and the conductive wire 2 is folded in half, and then inserted into the protective channel 31 of the protective end 3, so that the LED strip body 1 passes through the main channel 32 and the conductive wire 2 passes through the secondary channel 33; then, adhesive is filled into the protective channel 31, and after the adhesive has solidified, the protective end 3, the LED strip body 1, and the conductive wire 2 are connected as one unit. The protective end 3 can strengthen the protection of the connection between the LED strip body 1 and the conductive wire 2, improve the structural stability of the connection between the LED strip body 1 and the conductive wire 2, and thus improve the overall service life.
[0040] Example 2: This application discloses a light strip with a protective end.
[0041] The difference between the LED strip with a protective end disclosed in this application and Embodiment 1 is that:
[0042] Reference Figure 5 , Figure 6 In this embodiment, an end cap 4 is provided at the opening of the protective channel 31. The surface of the end cap 4 is provided with a through channel 41 for the light strip body 1 and the conductive wire 2 to pass through. The through channel 41 includes a first through hole 44 and a second through hole 45 that are interconnected. The light strip body 1 passes through the first through hole 44 and the conductive wire 2 passes through the second through hole 45. A sealing block 46 is fixedly installed at the connection between the first through hole 44 and the second through hole 45. The sealing block 46 is elastically set, and the two sides of the sealing block 46 abut against the outer peripheral wall of the light strip body 1 and the outer peripheral wall of the conductive wire 2, respectively.
[0043] A mating ring 42 is fixedly installed on the outer wall of the end cap 4. The mating ring 42 is ring-shaped around the outer side of the end cap 4 and is elastically set. An annular mating groove 35 is opened on the inner wall of the opening of the protective channel 31 for the mating ring 42 to be inserted. A plurality of extrusion blocks 43 embedded in the adhesive layer 34 are fixed on the surface of the end cap 4 near the protective channel 31.
[0044] The implementation principle of Embodiment 2 of this application is as follows: After injecting adhesive into the protective channel 31, the end cap 4 is placed over the opening of the protective channel 31, so that the mating ring 42 is embedded in the mating groove 35, completing the initial fixation between the end cap 4 and the protective end 3; the extrusion block 43 of the end cap 4 can extrude the adhesive in the protective channel 31, making the adhesive layer 34 after the adhesive solidifies more dense. In addition, after the adhesive solidifies to form the adhesive layer 34, the adhesive layer 34 wraps around the extrusion block 43, and the adhesive layer 34 connects the protective end 3, the end cap 4, the light strip body 1, and the conductive wire 2 into one, improving the overall structural stability.
[0045] Example 3: This application discloses a light strip with a protective end.
[0046] The difference between the LED strip with a protective end disclosed in this application and Embodiment 2 is that:
[0047] Reference Figure 7 In this embodiment, multiple insert pieces 5 are fixedly installed on the surface of the end cap 4 near the protective channel 31. The insert pieces 5 are inserted into the protective channel 31, and the adhesive layer 34 formed after the adhesive has cured wraps around the insert pieces 5. A deformation groove 51 is formed on the side wall of the insert piece 5 away from the end cap 4. The deformation groove 51 divides the insert piece 5 into a first abutment portion 52 and abutment portion 53. Under normal conditions (when the end cap 4 does not seal the opening of the protective end 3), there is a gap between the end of the first abutment portion 52 away from the end cap 4 and the end of the second abutment portion 53 away from the end cap 4. The end of the first abutment portion 52 away from the end cap 4 and the end of the second abutment portion 53 away from the end cap 4 converge towards the deformation groove 51. That is, the distance between the first abutment portion 52 and the second abutment portion 53 gradually decreases from the end closer to the end cap 4 to the end farther away from the end cap 4.
[0048] Multiple support rods 36 are fixedly installed on the inner wall of the protective channel 31. The multiple support rods 36 are correspondingly arranged with multiple plug-in pieces 5. Each support rod 36 has a pushing tip at one end near the end cover 4. When the end cover 4 closes the opening of the protective channel 31, the support rod 36 is inserted into the deformation groove 51, and the first abutting part 52 is forced to abut against the surface of the light strip body 1 and the second abutting part 53 is forced to abut against the surface of the conductive wire 2.
[0049] The implementation principle of Embodiment 3 of this application is as follows: When the end cap 4 blocks the opening of the protective channel 31, the support rod 36 is inserted into the deformation groove 51, thereby squeezing open the first abutment part 52 and the second abutment part 53, forcing the first abutment part 52 to abut against the surface of the light strip body 1 and the second abutment part 53 to abut against the surface of the conductive wire 2, thereby improving the connection stability between the light strip body 1 and the protective end 3, and between the conductive wire 2 and the protective end 3. After the adhesive in the protective channel 31 is cured, the adhesive layer 34 wraps around the plug piece 5, thereby connecting the protective end 3, the end cap 4, the light strip body 1 and the conductive wire 2 into one, improving the overall structural stability.
[0050] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
