Description

Technical Field

[0001] This invention application relates to the field of LED technology, specifically to an LED strip connector and an LED strip. Background Technology

[0002] LED light strips, with their advantages of high flexibility, uniform light emission, low energy consumption, and long lifespan, have been widely used in diverse scenarios such as architectural outline decoration, home ambient lighting, commercial window displays, and automotive interior embellishment. In practical applications, LED light strips often need to be cut to specific lengths according to usage requirements, and then mechanically fixed and electrically connected between the "light strip-power supply" and "light strip-light strips" using LED light strip connectors. Therefore, the performance of the connectors directly determines the installation efficiency, operational stability, and overall lighting effect of the LED light strip.

[0003] Chinese Patent Publication No. CN102694298B discloses an LED strip connector, including a connector cover, a connector seat, two limiting strips, and two metal pieces. The connector cover and connector seat are insulated. Each metal piece includes a metal tip and a metal tail, with the tail fixed to the connector seat. The limiting strips are installed on the inner surface of the connector cover or the inner surface of the connector seat. Each metal piece has a through hole. When the connector cover and connector seat are engaged, the two limiting strips pass through two connection points of the LED strip and extend into the two metal pieces, thus securing the LED strip to the metal pieces. This top-and-bottom engaging method is convenient and simple, effectively preventing the LED strip from detaching from the connector due to horizontal pulling. If the LED chip in the LED strip is damaged, the LED chip can be cut off, and the LED strip can be easily reconnected using the two connectors and conductors.

[0004] However, due to the significant differences in the required length of LED strip installations across various scenarios, the length of the accompanying power cord also needs to be flexibly adjusted. For example, in residential ceiling lighting, excessively long power cords need to be shortened to fit the compact space; in commercial window displays, even longer power cords are required to connect to a remote power source. In such cases, users often need to "cut the power cord and then reconnect" or "reconnect by replacing it with a different length of power cord," making it difficult to quickly align the power cord with the clamping slot. Repeated adjustments are required to complete the contact, which is especially time-consuming for non-professional users. Therefore, there is a current need for an LED strip connector that supports quick reconnection and replacement of power cords. Summary of the Invention

[0005] To address the aforementioned issues, an LED strip connector and LED strip are provided. The quick-connect mechanism enables rapid wire connection, allowing users to simply rotate the feed sleeve to quickly connect the wire without additional soldering or wiring, thus improving efficiency for initial or secondary wire connections.

The outer side of the rear end can fit against the inner wall of the extrusion sleeve. The length of the rear end is greater than the length of the extrusion sleeve and can move along the axis of the extrusion sleeve. A first metal plate is inlaid inside the front end. One end of the first metal plate communicates with the inside of the clamping groove, and the other end of the first metal plate extends outward from the front end. The top of the fixed base is provided with a terminal block that can be electrically connected to the first metal plate. The feed sleeve is located at the inlet. The feed sleeve can push the flexible clamping sleeve to move along the extrusion sleeve. The feed sleeve has external threads on its outside.

The slide rail is inlaid with a second metal plate that can contact one end of the terminal block and the first metal plate extending to the outside of the front end, respectively. The second metal plates are distributed on the slide rail along the moving direction of the front end.

[0008] Preferably, the inner ring of the extrusion sleeve is provided with a limiting block, and the outer front end is provided with a strip-shaped limiting groove for the limiting block to move horizontally.

The outer wall of the collar is movably fitted with the inner wall of the sleeve, and the collar can move along the axis of the sleeve.

[0011] Preferably, a knob is provided on the outside of the end of the feed sleeve away from the flexible clamping sleeve.

[0012] Preferably, a limiting disc is coaxially provided at one end of the feed sleeve near the flexible clamping sleeve. The diameter of the limiting disc is larger than the diameter of the nut. One end of the limiting disc abuts against the end of the flexible clamping sleeve away from the extrusion sleeve.

[0030] To further understand the features, technical means, and specific objectives and functions achieved by this invention application, the invention application will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1 to 4 and Figure 6As shown: An LED light strip connector includes a housing 1 and a wire 2. One end of the housing 1 is provided with a slot 11, and the end of the housing 1 away from the slot 11 is provided with a wire inlet 12. The inside of the housing 1 near the wire inlet 12 is provided with a wire quick-connect mechanism 3. The wire quick-connect mechanism 3 includes a fixing base 31, a flexible clamping sleeve 32, a compression sleeve 33 and a feeding sleeve 34. The mounting base 31 is disposed inside the housing 1; The extrusion sleeve 33 is horizontally set on the fixed base 31. The extrusion sleeve 33 is a flared structure with both ends open. The larger end of the extrusion sleeve 33 faces the inlet port 12, and the smaller end of the extrusion sleeve 33 is the retracted end. The flexible clamping sleeve 32 is movably disposed within the inner ring of the extrusion sleeve 33. The flexible clamping sleeve 32 is provided with a clamping groove 321 for inserting the power supply line 2. The flexible clamping sleeve 32 is integrally formed by the front end 322 and the rear end 323. The front end 322 is cylindrical and the rear end 323 is flared. The outer side of the rear end 323 can fit against the inner wall of the extrusion sleeve 33. The length of the rear end 323 is greater than the length of the extrusion sleeve 33 and can move along the axis of the extrusion sleeve 33. A first metal plate 35 is inlaid inside the front end 322. One end of the first metal plate 35 communicates with the inside of the clamping groove 321, and the other end of the first metal plate 35 extends outward from the front end 322. The top of the fixing base 31 is provided with a terminal 4 that can be electrically connected to the first metal plate 35. The feed sleeve 34 is located at the inlet 12. The feed sleeve 34 can push the flexible clamping sleeve 32 to move along the extrusion sleeve 33. The feed sleeve 34 has an external thread on its exterior. The inlet 12 of the housing 1 is provided with a nut 36 that mates with the external thread. The feed sleeve 34 has a power supply line 2 passing through the through hole 341.

[0032] When it is necessary to connect the wire 2, the user inserts the wire 2 into the clamping groove 321 of the flexible clamping sleeve 32 along the through hole 341 of the feed sleeve 34 until the conductor part of the wire 2 is in complete contact with the first metal piece 35 in the clamping groove 321. When the user holds the feed sleeve 34 and rotates it clockwise, the engagement between the external thread of the feed sleeve 34 and the internal thread of the nut 36, which is fixed on the housing 1, will generate an axial thrust, converting the rotation of the feed sleeve 34 into a linear movement along the axis of the housing 1 toward the flexible clamping sleeve 32. After the feed sleeve 34 moves to contact the rear end 323 of the flexible clamping sleeve 32, the feed sleeve 34 continues to rotate, and its axial thrust will push the flexible clamping sleeve 32 to move along the axis of the extrusion sleeve 33 toward the retracted end of the extrusion sleeve 33. Because the rear end 323 of the flexible clamping sleeve 32 is trumpet-shaped and completely fits the inner wall of the extrusion sleeve 33, as it moves toward the retracted end, the inclined inner wall of the extrusion sleeve 33 will generate a gradual extrusion force from weak to strong on the rear end 323 of the flexible clamping sleeve 32. The extrusion force intensity is controllable synchronously with the number of rotations of the feed sleeve 34. The more rotations, the farther the feed sleeve 34 moves, and the greater the extrusion force. The flexible clamping sleeve 32 undergoes elastic deformation under compression, and the range of the clamping groove 321 inside it gradually shrinks as the extrusion pressure increases, until it tightly wraps around and presses the outside of the wire 2, thus achieving a weldless mechanical fixation. When the feed sleeve 34 rotates to the preset torque, it stops rotating. At this time, the engagement between the external thread of the feed sleeve 34 and the internal thread of the nut 36 has a self-locking characteristic, which can prevent the feed sleeve 34 from rotating back due to vibration or pulling. When it is necessary to replace the wire 2, simply rotate the feed sleeve 34 in the opposite direction. The feed sleeve 34 will stop pushing the flexible clamping part. At this time, the clamping groove 321 of the flexible clamping sleeve 32 will stop applying force to the outside of the wire 2, and the user can easily take out the wire 2 and replace it.

[0033] The quick-connection mechanism 3 enables rapid connection of the wire 2. Users only need to rotate the feed sleeve 34 to quickly connect the wire 2 without additional soldering or wiring, thus improving efficiency for the first or second connection of the wire 2.

[0034] Reference Figure 7 , Figure 9 and Figure 10 As shown: The retracted end of the extrusion sleeve 33 is provided with a slide 331 on the side near the terminal 4. The front end 322 is slidably disposed on the slide 331. The slide 331 is inlaid with a second metal piece 332 that can contact one end of the terminal 4 and the first metal piece 35 extending to the outside of the front end 322 respectively. The second metal pieces 332 are distributed on the slide 331 along the moving direction of the front end 322.

[0035] When the user connects the wire 2, the wire 2, which is inserted into the clamping groove 321 of the flexible clamping sleeve 32, is in complete contact with the first metal piece 35. Since the flexible clamping sleeve 32 will move along the axis of the extrusion sleeve 33, a slide 331 for the front end 322 to move is provided at the retracted end of the extrusion sleeve 33. The second metal piece 332 embedded in the slide 331 is always in contact with the first metal piece 35. The second metal piece 332 is connected to the terminal 4. When the terminal 4 is connected to the LED light strip 6, the contact accuracy can be guaranteed and the poor contact caused by the offset can be reduced.

[0036] Reference Figure 7 As shown: The inner ring of the extrusion sleeve 33 is provided with a limiting block 333, and the front end 322 is provided with a strip-shaped limiting groove 3221 for the limiting block 333 to move horizontally.

[0037] A limiting block 333 is fixedly installed in the inner ring of the extrusion sleeve 33 at a position that does not affect the fit of the rear end 323 of the flexible clamping sleeve 32. The limiting block 333 is made of rigid material or plastic material. The limiting block 333 protrudes radially inward along the extrusion sleeve 33 and its position is aligned with the movement trajectory of the front end 322 of the flexible clamping sleeve 32. A strip-shaped limiting groove 3221 is opened on the outside of the front end 322 of the flexible clamping sleeve 32: the extension direction of the groove is completely consistent with the axial movement direction of the flexible clamping sleeve 32, and the length of the strip-shaped limiting groove 3221 is the safe movement stroke of the flexible clamping sleeve 32. When the limiting block 333 moves along the strip limiting groove 3221, the flexible clamping sleeve 32 cannot rotate around its own axis, ensuring that the first metal piece 35 on the front end 322 makes precise contact with the second metal piece 332.

[0038] Reference Figure 4 and Figure 8 As shown: A collar 324 is provided at the end of the flexible clamping sleeve 32 away from the extrusion sleeve 33. The collar 324 is on the same axis as the flexible clamping sleeve 32. A spring 325 is provided between the collar 324 and the extrusion sleeve 33. The spring 325 is sleeved on the outside of the flexible clamping sleeve 32.

[0039] The feed sleeve 34 moves along the axis toward the flexible clamping sleeve 32, first contacting the outer end face of the collar 324, that is, the side of the collar 324 away from the extrusion sleeve 33, and pushing the collar 324 toward the extrusion sleeve 33; when the collar 324 moves, it squeezes the spring 325, the spring 325 is compressed and generates an elastic reaction force. The greater the push of the elastic reaction force, the greater the compression and the stronger the reaction force. The elastic reaction force of the spring 325 can offset the sudden push of the feed sleeve 34, such as the impact force caused by the user rotating too fast, and avoid the flexible clamping sleeve 32 being pushed hard, resulting in uneven contact between the rear end 323 and the inner wall of the extrusion sleeve 33, or the sudden contraction of the clamping groove 321 damaging the wire 2; When it is necessary to disconnect the wire 2 and rotate the feed sleeve 34 in the opposite direction, the thrust on the collar 324 disappears, and the compressed spring 325 releases its elastic potential energy, generating an elastic force that pushes the collar 324 away from the compression sleeve 33. Under the action of the elastic force, the collar 324 drives the flexible clamping sleeve 32 to move away from the compression sleeve 33 until it returns to its initial position. After the flexible clamping sleeve 32 is reset, its internal clamping groove 321 naturally opens, and the user can easily pull out the wire 2 without manual prying or adjustment, thus improving the convenience of disassembly.

[0040] Reference Figure 4 and Figure 7As shown: A sleeve 334 is coaxially arranged at one end of the compression sleeve 33 near the spring 325. The collar 324, the spring 325 and the flexible clamping sleeve 32 are all located inside the sleeve 334. The outer wall of the collar 324 is movably fitted with the inner wall of the sleeve 334, and the collar 324 can move along the axis of the sleeve 334.

[0041] The sleeve 334 and the compression sleeve 33 are kept coaxial, so that the outer wall of the collar 324 is always in contact with the inner wall of the sleeve 334 and can only move directionally along the axis of the sleeve 334. This constrains the spring 325 to compress or extend uniformly along the axis and restricts the flexible clamping sleeve 32 from lateral displacement or rotation during movement. This ensures that the movement trajectory of the collar 324, spring 325 and flexible clamping sleeve 32 is precise and controllable, the elastic force of the spring 325 is stably transmitted along the axis, the flexible clamping sleeve 32 and the compression sleeve 33 fit more tightly, and the force is more uniform when the wire 2 is squeezed and fixed.

[0042] Reference Figure 4 and Figure 6 As shown: A knob 342 is provided on the outside of the end of the feed sleeve 34 away from the flexible clamping sleeve 32.

[0043] When the user holds the knob 342, rotational force can be easily applied, avoiding slippage caused by the small contact area when directly holding the feed sleeve 34. When the knob 342 is rotated, the force is transmitted through the feed sleeve 34 to the meshing point between its external thread and the internal thread of the nut 36, converting the rotational motion into axial movement of the feed sleeve 34 along the axis toward the flexible clamping sleeve 32. When it is necessary to disconnect wire 2, rotate knob 342 in the opposite direction and move away from flexible clamping sleeve 32 along the thread of nut 36. The thrust of feed sleeve 34 on collar 324 disappears, and compression spring 325 in sleeve 334 releases its elasticity, pushing collar 324 and flexible clamping sleeve 32 to retract synchronously with feed sleeve 34. Because the knob 342 is easy to operate and controllable, the user can precisely control the retraction distance until the clamping groove 321 of the flexible clamping sleeve 32 opens naturally, making it easy to pull out the wire 2.

[0044] Refer to 4 and Figure 6 As shown: A limiting disk 343 is coaxially provided at one end of the feed sleeve 34 near the flexible clamping sleeve 32. The diameter of the limiting disk 343 is larger than the diameter of the nut 36. One end of the limiting disk 343 abuts against the end of the flexible clamping sleeve 32 away from the extrusion sleeve 33. A through hole for the power supply line 2 to pass through is opened at the center of the limiting disk 343.

[0045] When the user rotates the knob 342 to move the feed sleeve 34 toward the flexible clamping sleeve 32, the limiting disk 343 moves synchronously with the feed sleeve 34. Since the limiting disk 343 directly abuts against the flexible clamping sleeve 32, the thrust of the feed sleeve 34 is transmitted to the flexible clamping sleeve 32 through the surface contact of the limiting disk 343, causing the flexible clamping sleeve 32 to move. When the user rotates the knob 342 in the opposite direction and disconnects the wire 2, causing the feed sleeve 34 to move away from the flexible clamping sleeve 32, the limiting plate 343 moves backward synchronously with the feed sleeve 34. When it moves to a certain distance, the limiting plate 343 will contact the outer end face of the nut 36 and be blocked. Because the diameter of the limiting plate 343 is larger than that of the nut 36, it cannot pass through the inner hole of the nut 36, thus preventing the feed sleeve 34 from falling off.

[0046] Reference Figure 4 and Figure 8 As shown: the end of the feed sleeve 34 with the through hole 341 away from the flexible clamping sleeve 32 is provided with a first chamfer 3411, and the opening of the clamping groove 321 of the flexible clamping sleeve 32 is provided with a second chamfer 3211.

[0047] When the user inserts wire 2, the first chamfer 3411 and the second chamfer 3211 work together to guide and transition the wire. The wire 2 first contacts the first chamfer 3411 of the feed sleeve 34 through hole 341. Since the first chamfer 3411 is an outwardly expanding inclined surface, even if the end of the wire 2 is slightly bent or uneven, or there is a slight deviation in the insertion angle, the chamfer can guide the wire 2 into the through hole 341 through the inclined surface, avoiding the end of the wire 2 being stuck by the right angle edge of the through hole 341, and greatly reducing the resistance of the initial insertion. After the wire 2 passes through the through hole 341 of the feed sleeve 34, it enters the opening of the clamping groove 321 of the flexible clamping sleeve 32. At this time, the second chamfer 3211 comes into play. The second chamfer 3211 expands the entrance range of the clamping groove 321. Even if the wire 2 is slightly offset due to long-distance insertion, it can be guided to the center of the clamping groove 321 by the chamfer, ensuring that the wire 2 enters the groove accurately and contacts the metal plate. This avoids the problem that the wire 2 is stuck at the edge of the clamping groove 321 and cannot go deeper due to misalignment.

[0048] Reference Figure 2 , Figure 5 and Figure 6 As shown: The top of the housing 1 is provided with a cover plate 5. A threaded sleeve 51 is provided through the cover plate 5 above the slot 11. A pressure plate 52 is provided below the threaded sleeve 51. A bolt 53 is vertically provided on the top of the pressure plate 52. One end of the bolt 53 is rotatably connected to the top of the pressure plate 52. The other end of the bolt 53 extends outward from the threaded sleeve 51 through the cover plate 5. The threaded sleeve 51 and the bolt 53 are threadedly engaged. The end of the terminal 4 away from the fixed seat 31 extends obliquely to the bottom of the pressure plate 52. An insulating pressure block 54 is provided at the bottom of the pressure plate 52, which can abut against the top of the terminal 4. Slider 521 is provided on both sides of the pressure plate 52. The inside of the housing 1 is provided with a limiting groove 13 for the vertical movement of the slider 521.

[0049] After the LED strip 6 is inserted into the slot 11 of the housing 1, the conductive end of the strip needs to be reliably connected to the terminal 4 through this structure. The user rotates the upper end of the bolt 53 outside the cover plate 5. Because the bolt 53 is threadedly engaged with the threaded sleeve 51, the rotational motion is converted into axial movement. The bolt 53 drives the pressure plate 52 to move downward in the vertical direction. As the pressure plate 52 descends, the bottom insulating pressure block 54 gradually approaches and eventually abuts against the inclined extension end of the terminal 4. As the bolt 53 continues to rotate, the insulating pressure block 54 applies downward pressure to the inclined terminal 4, forcing the terminal 4 to undergo slight elastic deformation, and its lower end bends towards the slot 11. After the terminal 4 is bent, its lower end is tightly fitted with the conductive end of the LED strip 6 inserted into the slot 11, such as the metal contact of the strip, to form a stable conductive path. When it is necessary to remove the LED strip or adjust the contact pressure, rotate the bolt 53 in the opposite direction; the bolt 53 drives the pressure plate 52 to move upward along the limiting groove 13, the insulating pressure block 54 separates from the terminal 4, the terminal 4 elastically resets, and disengages from the conductive end of the LED strip; at this time, the LED strip 6 can be easily pulled out, or the downward distance of the pressure plate 52 can be adjusted by adjusting the rotation of the fine-tuning bolt 53, thereby controlling the contact pressure between the terminal 4 and the LED strip.

[0050] An LED light strip includes the LED light strip connector described above.
