Description

TECHNICAL FIELD

[0001] The application relates to the technical field of LED, in particular to an LED lamp strip connector and an LED lamp strip. BACKGROUND

[0002] The LED lamp strip has been widely applied to various scenes such as building contour decoration, home atmosphere lighting, commercial showcase display and car interior decoration due to the advantages of strong flexibility, uniform light emission, low energy consumption and long service life. In actual application, the LED lamp strip often needs to be cut into a specific length according to the use requirement, and then the mechanical fixation and electrical connection between the lamp strip and the power supply or between the lamp strips are realized through the LED lamp strip connector. Therefore, the performance of the connector directly determines the installation efficiency, use stability and overall lighting effect of the LED lamp strip.

[0003] A kind of LED lamp strip connector is disclosed in Chinese authorized patent publication No.CN102694298B, which comprises a connector cover, a connector seat, two limiting strips and two metal sheets. The connector cover and the connector seat are insulating. The metal sheet comprises a metal sheet head and a metal sheet tail. The metal sheet tail is fixed on the connector seat. The limiting strips are installed on the inner surface of the connector cover or the inner surface of the connector seat. Two through holes are respectively formed in the two metal sheets. When the connector cover is clamped with the connector seat, the two limiting strips pass through the two connecting points of the LED lamp strip respectively and extend into the two metal sheets. The LED lamp strip is fixed with the metal sheet by passing through the two metal sheets. The upper and lower clamping mode is convenient and simple, and can effectively prevent the LED lamp strip from being separated from the connector due to pulling from the horizontal direction. When the LED chip of the LED lamp strip is damaged, the LED chip is cut off. The LED lamp strip can be conveniently connected by two connectors and a conductor.

[0004] However, due to the great difference in the demand for the length of the lamp strip laying in different scenes, the length of the matching wire also needs to be flexibly adjusted. For example, in home ceiling lighting, the wire needs to be cut short to adapt to the compact space. In commercial showcase display, longer wires need to be replaced to connect the remote power supply. At this time, the user often needs to "cut the wire and then connect it again" or "replace the wire of different length and connect it again", which leads to the difficulty of quickly aligning and clamping the wire, and the wire needs to be repeatedly adjusted to complete the contact. Especially for non-professional users, the single secondary connection often takes a long time. Therefore, there is a need for an LED lamp strip connector that supports quick secondary connection and replacement of the wire. SUMMARY

DETAILED DESCRIPTION

[0035] To further understand the features, technical means and specific purposes and functions achieved by the application, the application is described in further detail below in combination with the drawings and specific embodiments.

[0036] Reference Figures 1 to 4 and Figure 6As shown: an LED lamp strip connector, comprising a shell 1 and an electric wire 2, one end of the shell 1 is provided with a slot 11, the end of the shell 1 away from the slot 11 is provided with a wire inlet 12, the inside of the shell 1 near the wire inlet 12 is provided with an electric wire quick mounting mechanism 3, the electric wire quick mounting mechanism 3 comprises a fixed seat 31, a flexible clamping sleeve 32, a squeezing sleeve 33 and a feeding sleeve 34;

[0037] The fixed seat 31 is arranged in the inside of the shell 1;

[0038] The squeezing sleeve 33 is horizontally arranged on the fixed seat 31, the squeezing sleeve 33 is a horn structure with both ends open, the larger end of the squeezing sleeve 33 faces the wire inlet 12, and the smaller end of the squeezing sleeve 33 is a retracted end;

[0039] The flexible clamping sleeve 32 is movably arranged in the inner circle of the squeezing sleeve 33, the flexible clamping sleeve 32 is provided with a clamping groove 321 for inserting the electric wire 2, the flexible clamping sleeve 32 is integrally formed by a front end 322 and a rear end 323, the front end 322 is a cylinder, the rear end 323 is a horn, and the outside of the rear end 323 can be attached to the inner wall of the squeezing sleeve 33, the length of the rear end 323 is greater than the length of the squeezing sleeve 33, and the rear end 323 can move along the axis of the squeezing sleeve 33, the first metal sheet 35 is inlaid in the inside of the front end 322, one end of the first metal sheet 35 communicates with the inside of the clamping groove 321, the other end of the first metal sheet 35 extends to the outside of the front end 322, and the top of the fixed seat 31 is provided with a wiring terminal 4 capable of being electrically connected with the first metal sheet 35;

[0040] The feeding sleeve 34 is arranged at the wire inlet 12, the feeding sleeve 34 can push the flexible clamping sleeve 32 to move along the squeezing sleeve 33, the outside of the feeding sleeve 34 is provided with external threads, the wire inlet 12 of the shell 1 is provided with a screw cap 36 matched with the external threads, and the feeding sleeve 34 is provided with a through hole 341 for the electric wire 2 to pass through.

[0041] When the electric wire 2 needs to be connected, the user inserts the electric wire 2 into the clamping groove 321 of the flexible clamping sleeve 32 along the through hole 341 of the feeding sleeve 34 until the conductor part of the electric wire 2 is in complete contact with the first metal sheet 35 in the clamping groove 321;

[0042] The user holds the feeding sleeve 34 and rotates it clockwise, because the screw cap 36 is fixed on the shell 1, the meshing of the external threads of the feeding sleeve 34 and the internal threads of the screw cap 36 will generate an axial thrust, which converts the rotating action of the feeding sleeve 34 into linear movement along the axis of the shell 1 to the direction of the flexible clamping sleeve 32;

[0043] After the feeding sleeve 34 moves to contact the rear end 323 of the flexible clamping sleeve 32, the user continues to rotate the feeding sleeve 34, and the axial thrust of the feeding sleeve 34 will push the flexible clamping sleeve 32 to move along the axis of the squeezing sleeve 33 to the retracted end of the squeezing sleeve 33;

[0044] 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 to the retracted end, the inclined inner wall of the extrusion sleeve 33 will generate a gradually increasing extrusion force on the rear end 323 of the flexible clamping sleeve 32, and the extrusion force strength is synchronously controllable with the number of rotations of the feeding sleeve 34, the more the number of rotations, the farther the moving distance of the feeding sleeve 34, and the greater the extrusion force;

[0045] The flexible clamping sleeve 32 is elastically deformed by extrusion, and the range of the clamping groove 321 inside it gradually decreases with the increase of the extrusion force, until it tightly wraps and compresses the outside of the wire 2, realizing the welding-free mechanical fixation;

[0046] When the feeding sleeve 34 rotates to the preset torque and stops rotating, the engagement of the outer threads of the feeding sleeve 34 and the inner threads of the nut 36 has a self-locking feature, which can prevent the feeding sleeve 34 from rotating backward due to vibration or pulling;

[0047] When it is necessary to replace the wire 2, the feeding sleeve 34 only needs to be rotated in the reverse direction, and the feeding sleeve 34 stops pushing the flexible clamping part, at this time, the clamping groove 321 of the flexible clamping sleeve 32 stops applying force to the outside of the wire 2, and the user can easily take out and replace the wire 2.

[0048] The wire quick-mounting mechanism 3 realizes the effect of quickly connecting the wire 2, and the user only needs to rotate the feeding sleeve 34 to realize the quick mounting of the wire 2, without the need for additional welding or wiring, which improves the efficiency of the first or second connection of the wire 2.

[0049] Referring to Figure 7 、 Figure 9 and Figure 10 , the retracted end of the extrusion sleeve 33 is provided with a slide 331 on one side close to the terminal 4, the front end 322 is slidably arranged on the slide 331, and the second metal sheet 332 is inlaid in the slide 331 and can contact the first metal sheet 35 and the terminal 4.

[0050] When the user connects the wire 2, the wire 2 inserted into the clamping groove 321 of the flexible clamping sleeve 32 is in complete contact with the first metal sheet 35, and because the flexible clamping sleeve 32 will move along the axis of the extrusion sleeve 33, the slide 331 is provided at the retracted end of the extrusion sleeve 33 for the movement of the front end 322, the second metal sheet 332 inlaid in the slide 331 is always in contact with the first metal sheet 35, and the second metal sheet 332 is connected with the terminal 4, which can ensure the contact accuracy and reduce the poor contact caused by deviation when the terminal 4 is connected with the LED lamp strip 6.

[0051] Referring to Figure 7As shown: the inner ring of the extrusion sleeve 33 is provided with a limiting block 333, and the outer part of the front end 322 is provided with a strip-shaped limiting slot 3221 for horizontal movement of the limiting block 333.

[0052] A limiting block 333 is fixedly arranged at the position where the inner ring of the extrusion sleeve 33 does not affect the adhesion of the rear end 323 of the flexible clamping sleeve 32. The limiting block 333 is made of rigid material or plastic material, and protrudes radially inward along the extrusion sleeve 33, and is aligned with the movement track of the front end 322 of the flexible clamping sleeve 32.

[0053] A strip-shaped limiting slot 3221 is formed in the outer part of the front end 322 of the flexible clamping sleeve 32. The extension direction of the slot is completely consistent with the axial movement direction of the flexible clamping sleeve 32, and the length of the strip-shaped limiting slot 3221 is the safe movement stroke of the flexible clamping sleeve 32.

[0054] When the limiting block 333 moves along the strip-shaped limiting slot 3221, the flexible clamping sleeve 32 cannot rotate around its own axis, ensuring that the first metal sheet 35 and the second metal sheet 332 on the front end 322 are in precise contact.

[0055] Referring to Figure 4 and Figure 8 As shown: the end of the flexible clamping sleeve 32 away from the extrusion sleeve 33 is provided with a sleeve ring 324, the sleeve ring 324 has the same axis as the flexible clamping sleeve 32, a spring 325 is arranged between the sleeve ring 324 and the extrusion sleeve 33, and the spring 325 is arranged outside the flexible clamping sleeve 32.

[0056] The feeding sleeve 34 moves along the axis towards the flexible clamping sleeve 32, first contacts the outer side surface of the sleeve ring 324, i.e. the side of the sleeve ring 324 away from the extrusion sleeve 33, and pushes the sleeve ring 324 to move towards the extrusion sleeve 33; when the sleeve ring 324 moves, the spring 325 is compressed and generates an elastic reaction force. The greater the pushing force of the spring 325, the greater the compression amount, and the stronger the reaction force. The elastic reaction force of the spring 325 can offset the sudden pushing force of the feeding sleeve 34, such as the impact force caused by the user rotating too fast, to avoid the flexible clamping sleeve 32 being pushed hard to cause the rear end 323 to adhere unevenly to the inner wall of the extrusion sleeve 33, or the clamping slot 321 to suddenly shrink and injure the electric wire 2.

[0057] When the electric wire 2 needs to be disassembled and the feeding sleeve 34 is reversely rotated, the pushing force on the sleeve ring 324 disappears, the spring 325 in the compressed state releases the elastic potential energy and generates an elastic force to push the sleeve ring 324 away from the extrusion sleeve 33; under the action of the elastic force, the sleeve ring 324 drives the flexible clamping sleeve 32 to move away from the extrusion sleeve 33 until it returns to the initial position. After the flexible clamping sleeve 32 is reset, the clamping slot 321 in the flexible clamping sleeve 32 naturally opens, and the user can easily pull out the electric wire 2 without manually prying or adjusting, thereby improving the disassembly convenience.

[0058] Referring toFigure 4 and Figure 7 As shown in FIG. 4 and FIG. 5, the one end of the extrusion sleeve 33 close to the spring 325 is coaxially provided with a sleeve 334, the sleeve ring 324, the spring 325 and the flexible clamping sleeve 32 are all arranged in the sleeve 334, the outer wall of the sleeve ring 324 is movably attached to the inner wall of the sleeve 334, and the sleeve ring 324 can move along the axis of the sleeve 334.

[0059] The sleeve 334 is coaxial with the extrusion sleeve 33, so that the outer wall of the sleeve ring 324 is always movably attached to the inner wall of the sleeve 334 and can only move along the axis of the sleeve 334, thereby restricting the spring 325 from being uniformly compressed or elongated along the axis and limiting the flexible clamping sleeve 32 from being laterally deviated or rotated during movement, ensuring that the movement trajectory of the sleeve ring 324, the spring 325 and the flexible clamping sleeve 32 is accurately controllable, the spring force of the spring 325 is stably transmitted along the axis, the flexible clamping sleeve 32 is more closely attached to the extrusion sleeve 33, and the electrical wire 2 is more uniformly stressed when being extruded and fixed.

[0060] Referring to FIG. 4 and FIG. 5, Figure 4 and Figure 6 As shown in FIG. 4 and FIG. 5, the one end of the extrusion sleeve 33 close to the spring 325 is coaxially provided with a sleeve 334, the sleeve ring 324, the spring 325 and the flexible clamping sleeve 32 are all arranged in the sleeve 334, the outer wall of the sleeve ring 324 is movably attached to the inner wall of the sleeve 334, and the sleeve ring 324 can move along the axis of the sleeve 334.

[0061] The user holds the knob 342, which can easily exert a rotating force, avoiding the problem of slipping caused by small contact area when directly holding the feed sleeve 34; when rotating the knob 342, the force is transmitted to the meshing part between the external threads of the feed sleeve 34 and the internal threads of the nut 36, converting the rotating motion into the axial movement of the feed sleeve 34 along the axis towards the flexible clamping sleeve 32;

[0062] When the electrical wire 2 needs to be disassembled, the knob 342 is rotated in the opposite direction, moving along the threads of the nut 36 away from the flexible clamping sleeve 32, the pushing force of the feed sleeve 34 on the sleeve ring 324 disappears, the compressed spring 325 in the sleeve 334 releases the spring force, pushing the sleeve ring 324 and the flexible clamping sleeve 32 to retreat synchronously with the feed sleeve 34;

[0063] Since the knob 342 is labor-saving and controllable, the user can accurately control the retreat distance until the clamping groove 321 of the flexible clamping sleeve 32 naturally opens, and the electrical wire 2 can be easily pulled out.

[0064] Referring to FIG. 4 and FIG. 5, Figure 6 As shown in FIG. 4 and FIG. 5, the one end of the extrusion sleeve 33 close to the spring 325 is coaxially provided with a sleeve 334, the sleeve ring 324, the spring 325 and the flexible clamping sleeve 32 are all arranged in the sleeve 334, the outer wall of the sleeve ring 324 is movably attached to the inner wall of the sleeve 334, and the sleeve ring 324 can move along the axis of the sleeve 334.

[0065] When the user rotates the knob 342 to move the feeding sleeve 34 towards the flexible clamping sleeve 32, the limiting disc 343 moves synchronously with the feeding sleeve 34, and since the limiting disc 343 directly abuts the flexible clamping sleeve 32, the pushing force of the feeding sleeve 34 is transmitted to the flexible clamping sleeve 32 through the surface contact of the limiting disc 343, so that the flexible clamping sleeve 32 moves;

[0066] When the user reversely rotates the knob 342 to remove the electric wire 2 and moves the feeding sleeve 34 away from the flexible clamping sleeve 32, the limiting disc 343 moves synchronously with the feeding sleeve 34, and when it moves to a certain distance, the limiting disc 343 will be in contact with the outer end surface of the screw cap 36 and be blocked, because the diameter of the limiting disc 343 is larger than that of the screw cap 36, it cannot pass through the inner hole of the screw cap 36, thereby avoiding the falling of the feeding sleeve 34.

[0067] Referring to Figure 4 , Figure 8 , the first chamfer 3411 is arranged at the end of the feeding sleeve 34 away from the flexible clamping sleeve 32, and the second chamfer 3211 is arranged at the opening of the clamping groove 321 of the flexible clamping sleeve 32.

[0068] When the user inserts the electric wire 2, the first chamfer 3411 and the second chamfer 3211 cooperatively play a guiding and transition role;

[0069] The electric wire 2 first contacts the first chamfer 3411 of the feeding sleeve 34, and since the first chamfer 3411 is an outwardly expanding inclined surface, even if the end of the electric wire 2 is slightly bent, uneven, or the insertion angle has a slight deviation, the chamfer can guide the electric wire 2 into the inside of the perforation 341 through the inclined surface, avoiding the end of the electric wire 2 being stuck by the right-angle edge of the perforation 341, and greatly reducing the resistance of initial insertion;

[0070] After the electric wire 2 passes through the perforation 341 of the feeding sleeve 34, it enters the opening of the clamping groove 321 of the flexible clamping sleeve 32, and at this time, the second chamfer 3211 plays a role, the second chamfer 3211 expands the entrance range of the clamping groove 321, even if the electric wire 2 is slightly offset due to long-distance insertion, it can also be guided to the center of the clamping groove 321 by the chamfer, ensuring that the electric wire 2 accurately enters the groove and contacts the metal sheet, avoiding the problem that the electric wire 2 is stuck on the edge of the clamping groove 321 and cannot be deeply inserted due to misalignment.

[0071] Referring to Figure 2 , Figure 5 , and Figure 6As shown: the top of the shell 1 is provided with a cover plate 5, the cover plate 5 is located above the through threaded sleeve 51 provided with a threaded sleeve 51, the lower part of the threaded sleeve 51 is provided with a pressing plate 52, the top of the pressing plate 52 is vertically provided with a bolt 53, one end of the bolt 53 is rotatably connected with the top of the pressing plate 52, the other end of the bolt 53 extends to the outside of the cover plate 5 through the threaded sleeve 51, the threaded sleeve 51 is screwed with the bolt 53, the end of the terminal 4 away from the fixed seat 31 is inclined to extend to the lower part of the pressing plate 52, the bottom of the pressing plate 52 is provided with an insulating block 54 capable of abutting against the top of the terminal 4, the two sides of the pressing plate 52 are provided with sliding blocks 521, the inside of the shell 1 is provided with a limiting groove 13 for the vertical movement of the sliding block 521.

[0072] When the LED lamp strip 6 is inserted into the slot 11 of the shell 1, the structure is needed to reliably connect the conductive end of the lamp strip with the terminal 4, the user rotates the upper end of the bolt 53 outside the cover plate 5, because the bolt 53 is screwed with the threaded sleeve 51, the rotating movement is converted into axial movement, the bolt 53 drives the pressing plate 52 to move downward along the vertical direction;

[0073] When the pressing plate 52 descends, the insulating block 54 at the bottom gradually approaches and finally abuts against the inclined extension end of the terminal 4, with the continuous rotation of the bolt 53, the insulating block 54 exerts downward pressure on the inclined terminal 4, forcing the terminal 4 to slightly elastically deform, and the lower end thereof bends to the direction of the slot 11;

[0074] After the terminal 4 is bent, the lower end thereof is tightly attached to the conductive end of the LED lamp strip 6 inserted into the slot 11, such as the metal contact of the lamp strip, to form a stable conductive path;

[0075] When it is needed to disassemble the lamp strip or adjust the contact pressure, the bolt 53 is reversely rotated; the bolt 53 drives the pressing plate 52 to move upward along the limiting groove 13, the insulating block 54 is separated from the terminal 4, the terminal 4 elastically resets and is separated from the conductive end of the lamp strip; at this time, the LED lamp strip 6 can be easily pulled out, or the rotation amount of the bolt 53 is adjusted to adjust the descending distance of the pressing plate 52, so as to control the contact pressure of the terminal 4 with the lamp strip.

[0076] An LED lamp strip, comprising the above-mentioned LED lamp strip connector.
