Description

Technical Field

[0001] The utility model relates to a lighting fixture accessory, and particularly discloses a high-strength intermediate connection component of an LED light strip. Background Art

[0002] The existing intermediate joint for an LED light strip, reference publication number 210462581U, describes an intermediate joint for a wireless LED light strip. The intermediate joint has light strip grooves at both ends, with pins electrically connected to each other between the two grooves. A fastening cover is provided on the upper opening of the light strip groove. One side of the fastening cover is integrally connected to the light strip groove via a thin sheet of material. The other side of the fastening cover has a latch hole, and a buckle that mates with the latch hole is provided on the other side of the light strip groove. The connection method is as follows: first, the LED light strip is inserted into the light strip groove through the end opening until the pins electrically contact the wiring terminals on the LED light strip circuit board, thereby electrically connecting the two sections of the LED light strip. The fastening cover is then closed, allowing the latch on the light strip groove to engage with the latch hole of the fastening cover, thereby clamping the LED light strip in the light strip groove. Because the fastening cover is connected to one side of the light strip slot via a thin sheet of material, the cover and slot must be made of a tough, low-hardness material to prevent the sheet from breaking due to repeated opening and closing, which can easily deform under stress. Furthermore, because the other side of the fastening cover is secured to the light strip slot via a latch and buckle, the latch requires a certain amount of clearance to return, resulting in a low locking force. Consequently, existing intermediate connection structures for LED light strips have drawbacks such as the LED strip being easily loosened, poor electrical contact between the LED strip and the conductive strip, and fire hazards. Utility Model Content

[0003] Based on this, it is necessary to provide an intermediate connection component for LEDs with a simple structure, easy installation and high connection strength to address the existing technical problems.

[0004] In order to solve the problems of the existing technology, the utility model discloses a high-strength intermediate connection component of an LED light strip, including an intermediate joint, the intermediate joint including a main body, light strip grooves are provided at both ends of the main body, and a number of pins corresponding to the electric contact terminals of the LED light strip are provided in the light strip groove, the light strip groove is formed by a bottom plate extending from the main body and two opposite side plates, the side plates and the bottom plate are separated from each other in the light strip groove, the light strip groove and the side plates have an end close to the main body as an inner end, and an end away from the main body as an outer end; it also includes a fixing sleeve, the fixing sleeve includes two opposite side walls and opposite upper and lower walls; when the fixing sleeve is connected to the light strip groove, the two side walls of the fixing sleeve are interference fit with the light strip groove, and the width of the outer end of the light strip groove is smaller than the width of the inner end.

[0005] The beneficial effects of the present invention are as follows: since the two side walls of the fixing sleeve compress the two side plates of the light strip groove, the width of the outer end of the light strip groove is smaller than the width of the inner end, the two side plates of the light strip groove can compress the LED light strip, so that the deformation of the outer skin of the LED light strip at the outer end of the light strip groove is greater than that at the inner end. The connection strength of the LED light strip is high, it can withstand large tensile force, has good durability, and has a simple structure and is easy to install.

[0006] The present invention can be further improved as follows: the two side walls of the fixing sleeve are parallel to each other, and the thickness of the outer end of the side panel is greater than the thickness of the inner end. A baffle is provided at one end of the fixing sleeve to cooperate with the end face of the light strip groove, and the baffle abuts against the end face of the light strip groove. The side panels and the bottom plate are provided with anti-slip teeth facing the inner end of the light strip groove. The pins are fixed on the main body, and their two ends are respectively inserted into the two LED light strips to be electrically connected with their contact terminals. Several mounting holes leading to the two light strip grooves are provided in the main body, and a conductive sleeve is provided in the mounting hole, and the two ends of the sleeve are retracted into the mounting hole; a group of pins are respectively provided in the two light strip grooves, and the pins are inserted in the fixing part, and the fixing part fixes the spacing of the several pins. One end of the two groups of pins are respectively inserted into the two LED light strips to be electrically connected with their contact terminals, and the other ends of the two groups of pins are inserted into the sleeve to be electrically connected to each other. The upper wall and lower wall of the fastening sleeve are clamped on the upper surface and lower surface of the light strip groove, so that the pins are in close contact with the electric contact terminals of the LED light strip. The intermediate joint and the fastening sleeve are made of hard plastic. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Embodiment 1, refer to Figure 1 The high-strength intermediate connecting structure of the LED lamp strip includes two LED lamp strips 1 and an intermediate connecting assembly connecting the two LED lamp strips 1, and the intermediate connecting assembly includes an intermediate joint 2 and a fastening sleeve 3.

[0017] Refer to Figure 5 The LED lamp strip 1 includes a flexible circuit board 11, a plurality of LED lamp beads 12 mounted on the flexible circuit board 11, a plurality of live terminals 13 arranged on the flexible circuit board 11 and a flexible outer skin 14 wrapping the flexible circuit board 11. The circuit board 11 includes a circuit layer and a back insulating film and a front insulating film arranged on both sides of the circuit layer respectively, the circuit layer is provided with a power circuit and a signal circuit, the front insulating film is provided with a window corresponding to the position of the circuit, and the live terminal 13 is a soldering tin in the window and in electrical contact with the power circuit and the signal circuit.

[0018] Refer to Figures 3 to 5 The intermediate joint 2 is made of hard plastic and includes a body 21, and the body 21 is provided with a lamp strip groove 22 at both ends. The lamp strip groove 22 is formed by two opposite side plates 221 and a bottom plate 222 extending from the body 21. The side plates 221 and the bottom plate 222 are disconnected from each other in the lamp strip groove 22 except that they are connected to the body 21, that is, the three can be independently bent and deformed. The side plate 221 and the lamp strip groove 22 have an inner end close to one end of the body 21 and an outer end away from the body 21. The outer end of the side plate 221 is thicker than the inner end, and the specific embodiment includes two kinds, one of which is as shown in Figure 3 The inner side surfaces 22b of the two side walls 221 are parallel to each other, and the outer side surfaces 22a are inclined to each other; the other is as shown in Figure 4As shown, the outer sides 22b of the two side walls 221 are parallel to each other, while their inner sides 22b are inclined toward each other. Sharp anti-slip teeth 25 are provided on the inner sides of the side panels 221 and bottom panel 222, facing the inner ends of the light strip slots 22. The main body 21 is also provided with at least two pins 24, the middle portions of which are fixed within the main body 21, with both ends extending into the two light strip slots 22. In LED light strips that require transmission of control signals, more than two pins 24 may be provided.

[0019] refer to Figure 2 The fastening sleeve 3 is made of hard plastic and includes two parallel side walls 31 and parallel upper and lower walls 32 and 33. One end of the fastening sleeve 3 is provided with a retaining plate 34 that engages the end of the light strip slot 22. The other end is a straight-through end. The two side walls 31 of the fastening sleeve 3 are interference-fitted with the two side panels 221 of the light strip slot 22.

[0020] refer to Figure 5 The assembly method of the present invention is as follows: first, the two fastening sleeves 3 are respectively attached to the two LED light strips 1, with the straight ends of the fastening sleeves 3 facing the ends of the LED light strips 1; then, the ends of the two LED light strips 1 are aligned with the pins 24 and inserted from the end opening of the light strip slot 22 to the bottom of the light strip slot 22. At this time, the two ends of the two pins 24 are respectively inserted into the two LED light strips 1 and electrically contact the two contact terminals 13 on their circuit boards 21; finally, the fastening sleeve 3 is attached to the light strip slot 22 until its baffle 34 abuts against the end surface of the light strip slot 22. Of course, the side walls 31 of the fastening sleeve 3 can also be set to be inclined relative to each other, and the outer and inner ends of the side walls 221 of the light strip slot 22 are equal in thickness.

[0021] refer to Figure 7The LED lamp strip 1 is connected with the intermediate connector 2. Since the two side walls 31 of the fastening sleeve 3 are in interference fit with the two side plates 221 of the lamp strip groove 22, and the thickness of the outer end of the side plate 221 is greater than that of the inner end, the two side walls 31 of the fastening sleeve 3 press the two side plates 221 of the lamp strip groove 22, so that the outer end width L1 of the lamp strip groove 22 is smaller than the inner end width L2. At this time, the lamp strip groove 22 can be in interference fit with the LED lamp strip 1 only at the outer end, and in clearance fit with the LED lamp strip 1 at the inner end; or the whole of the lamp strip groove 22 from the outer end to the inner end is in interference fit with the LED lamp strip 1, but the interference amount at the outer end is greater than that at the inner end. In both cases, the flexible outer skin 14 of the LED lamp strip 1 deforms after being pressed by the two side plates 221 of the lamp strip groove 22, and the deformation amount of the outer skin 14 at the outer end of the lamp strip groove 22 is greater than that at the inner end. In this way, the LED lamp strip 1 is equivalent to being clamped in the lamp strip groove 22, and the connection strength of the LED lamp strip 1 is high and can withstand large tension. Even, since the side wall 221 is made of hard material, the sharp anti-slip teeth 25 on the side plate 1 can pierce the outer skin 14 of the LED lamp strip 1, which can increase the friction and further improve the connection strength of the LED lamp strip. The upper wall 32 and the lower wall 33 of the fastening sleeve 3 are clamped on the upper and lower surfaces of the lamp strip groove 22 to provide support for the bottom plate 222, so that the live terminal 13 of the LED lamp strip 1 maintains close electrical contact with the pin 24. Since the power connector 1 and the fastening sleeve 3 do not need to be repeatedly folded components, they can be made of hard plastic, the fastening sleeve 3 has a closed ring structure and good integrity, and the fastening force and durability are better. Since the two side walls 31 of the fastening sleeve 3 are parallel to each other, the interference fit structure is arranged on the lamp strip groove 22, the intermediate connector 2 can use two fastening sleeves 3 to fasten two lamp strip grooves 22 respectively, or use one longer fastening sleeve 3 to fasten two lamp strip grooves 22 at the same time, and the fastening sleeve 3 has higher design and use freedom.

[0022] Embodiment 2. The structure of this embodiment is mostly the same as that of embodiment 1, and the following mainly describes the different parts, and the parts not described can refer to embodiment 1. Figure 6 and Figure 8The main body 21 is provided with a plurality of mounting holes 27 leading to the two light strip slots 22. A conductive sleeve 28 is provided in the mounting holes, and both ends of the sleeve 28 are retracted into the mounting holes 27. Each of the two light strip slots 22 is provided with a group of pins 24. The pins 24 are inserted into a fixing portion 241. The fixing portion 241 ensures that the spacing between one end of the pins 24 is equal to the spacing between the terminal blocks 23 on the LED light strip, and the spacing between the other ends is equal to the spacing between the sleeves 28. The installation method of this embodiment differs from that of Example 1 in that: first, one end of the two groups of pins 24 is inserted into the ends of the two LED light strips 1 respectively, so that they contact the electric contact terminals 23 on the LED light strips 1. Then, the two LED light strips are inserted into the two light strip slots 22 respectively, and the other ends of the pins 24 are inserted into the sleeves 28. Since the sleeve 28 is retracted into the mounting hole 27 , when only the LED light strip 1 at one end of the intermediate joint is replaced, even if the LED light strip 1 at the other end is already connected to the mains, there is no risk of electric shock during live operation, and the construction safety index is higher.

[0023] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
