Description

Technical Field

[0001] The utility model relates to the technical field of LED strip connectors, and particularly relates to a waterproof LED strip connector. Background Art

[0002] With the development of LED lighting technology, LED strips are widely used in indoor and outdoor decorative lighting fields due to their energy-saving, environmental protection, long lifespan and other characteristics. However, during the use of LED strips, they often need to be connected to a power source. Especially when used outdoors, the waterproof performance of the strip connector becomes an important consideration.

[0003] For example, the Chinese utility model patent with the authorization publication number CN204300793U and the patent name of an LED strip waterproof connector specifically discloses an LED strip waterproof connector. Its plug-in part is connected to the conductive pin connection end of the power connector, and the LED strip is installed in the installation grooves at both ends of the silicone sleeve. And the conductive pins of the plug-in part first pass through the through holes on the silicone sleeve and then extend into the strip plug-in grooves to be electrically connected to the strip. When the silicone sleeve is placed in the accommodation cavity of the silicone sleeve installation box, when the bottom box and the box cover of the silicone sleeve installation box are closed and tightened, due to the extrusion of the box body on the silicone sleeve, and the silicone sleeve itself has elasticity, thus the LED strip, the plug-in part and the conductive pin connection end of the power connector respectively installed in the installation grooves at both ends of the silicone sleeve are all squeezed by the silicone sleeve and clamped tightly, so it is difficult to loosen. And due to the extrusion of the silicone sleeve, the connection positions of the strip and the conductive pins of the plug-in part, and the connection positions of the power connector and the conductive pins of the plug-in part are all tightly attached by the silicone sleeve, thus achieving a good waterproof effect.

[0004] Although the above-disclosed patent text solves the technical problem of waterproofing of the strip connector, its structure is complex and there are many components, resulting in cumbersome installation steps and relatively high production and installation costs. Due to its complex structure and difficult installation, and the strip is directly connected to the conductive pins of the power connector, during installation, the conductive pins of the strip and the power connector are prone to being connected reversely, resulting in the strip not working properly or even being damaged. If installed wrongly, it needs to be disassembled and reinstalled again, which is time-consuming and laborious.

[0005] Therefore, how to overcome the above-mentioned existing defects has become an important issue that needs to be urgently solved by those skilled in the art. Summary of the Utility Model

[0006] The utility model overcomes the above technical deficiencies and provides a waterproof LED strip connector with a simple structure, convenient installation, and capable of effectively preventing the positive and negative poles of the strip from being connected reversely with the power connector.

[0007] To achieve the above object, the utility model adopts the following technical solutions:

[0008] A waterproof LED strip connector, comprising a power connector, a strip connection base inserted into the power connector, and a strip inserted into the strip connection base. The power connector is provided with first positive and negative conductive pins electrically connected to an external power supply. The strip connection base is provided with second positive and negative conductive pins inserted into the first positive and negative conductive pins. A limiting and guiding structure is arranged between the strip connection base and the power connector to prevent the positive and negative poles from being connected reversely when the first positive and negative conductive pins are inserted into the second positive and negative conductive pins. The strip connection base is tightly inserted into the power connector through the limiting and guiding structure. A sealing structure is arranged on the power connector and the strip connection base.

[0009] Further, the limiting and guiding structure includes a first sliding rail arranged on the outer wall of the strip connection base, and a first sliding groove opened on the inner wall of the power connector and adapted to the structure of the first sliding rail for the first sliding rail to insert into.

[0010] Further, the limiting and guiding structure includes a second sliding rail arranged on the outer wall of the strip connection base, and a second sliding groove opened on the inner wall of the power connector and adapted to the structure of the second sliding rail for the second sliding rail to insert into. The groove width of the second sliding groove is greater than or less than that of the first sliding groove.

[0011] Further, the sealing structure includes a waterproof rubber ring arranged at the upper ends of the strip connection base and the power connector.

[0012] Further, the strip connection base includes a base and a cover body hinged to one end of the base. The other end of the cover body is buckled on the base through a buckle structure.

[0013] Further, the buckle structure includes a clamping block arranged on the base and a clamping groove opened on the side wall of the cover body for the clamping block to be clamped into.

[0014] Further, a plurality of protrusions are uniformly arranged on the inner wall of the upper end of the cover body, and the protrusions extend downward along the inner wall of the upper end of the cover body to form a conical shape.

[0015] Further, a slot for the strip to be inserted is arranged on the base, and a guide rail protruding upward is arranged at the bottom of the slot. The guide rail includes a ramp end.

[0016] Further, one end of the second positive and negative conductive pins extends out of the base and the other end extends into the slot. The strip is provided with third positive and negative conductive pins.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] 1. A waterproof LED strip connector provided in this case includes a power connector, a strip connection base inserted into the power connector, and a strip inserted into the strip connection base. In this case, the installation and power-on of the strip can be completed only through three components, with a simple structure and convenient installation. Inside the power connector, there are first positive and negative conductive pins electrically connected to an external power source, and on the strip connection base, there are second positive and negative conductive pins inserted into the first positive and negative conductive pins. By setting a limit and guiding structure between the strip connection base and the power connector in this case, it can effectively prevent the positive and negative poles from being reversed when the first positive and negative conductive pins are inserted into the second positive and negative conductive pins.

[0019] 2. A sealing structure is provided on the power connector and the strip connection base, which plays a good waterproof role.

[0020] 3. On the base of the strip connection base in this case, there is a slot for the strip to be inserted, and at the bottom of the slot, there is a guide rail protruding upward. The guide rail includes a sloped end for facilitating the insertion of the strip. By setting a guide rail with a sloped end, the strip can be inserted into the slot more conveniently and accurately under the action of the guide rail and connected to the second positive and negative conductive pins. At the same time, the guide rail with a sloped end avoids the situation where the positive and negative poles are reversed when the third positive and negative conductive pins of the strip are inserted into the second positive and negative conductive pins of the strip connection base, preventing the situation where the strip cannot be powered on after installation or causing damage to the strip. At the same time, the sloped end of the guide rail cooperates with the protrusion provided on the upper cover of the strip connection base. After the strip is installed, the strip can be more stably and tightly fitted into the strip connection base, not easily loosening, effectively reducing the gap between the strip connection base and the strip, further improving the waterproof performance, and reducing the possibility of moisture intrusion.

[0025] The following further details the features of the present utility model and other related features through embodiments for the understanding of those skilled in the same industry:

[0026] Such as Figures 1 - 4As shown in the figure, this case discloses a waterproof LED strip connector, which includes a power connector 1, a strip connection base 2 inserted into the power connector 1, and a strip 3 inserted into the strip connection base 2. Specifically, when implemented, an installation cavity is provided inside the power connector 1, and the strip connection base 2 is tightly embedded in the installation cavity. The other end of the power connector 1 is connected to a plug through a power cord, so as to be connected to an external power source to provide power for the LED strip connector in this case. The strip 3 is an LED strip with a layer of resin or silicone wrapped on the outside to form a closed structure and achieve a good waterproof effect. The power connector 1 is provided with first positive and negative conductive pins 11 electrically connected to the external power source. It should be noted that in order to reduce the installation steps and facilitate the installation of the LED strip connector in this case, the first positive and negative conductive pins 11 are integrally formed inside the power connector 1. The strip connection base 2 is provided with second positive and negative conductive pins 21 inserted into the first positive and negative conductive pins 11. In order to reduce the installation steps and facilitate the installation of the LED strip connector in this case, the second positive and negative conductive pins 21 are integrally formed inside the power connector 1. The first positive and negative conductive pins 11 and the second positive and negative conductive pins 21 are made of materials with good electrical conductivity, such as copper or silver-plated copper. A limiting and guiding structure is provided between the strip connection base 2 and the power connector 1 to prevent the positive and negative poles from being reversed when the first positive and negative conductive pins 11 are inserted into the second positive and negative conductive pins 21. The strip connection base 2 is tightly inserted into the power connector 1 through the limiting and guiding structure. By setting the limiting and guiding structure, the correct connection of the positive and negative poles is ensured. Only when the strip connector 2 is correctly positioned with the power connector 1 can the strip connector 2 be smoothly inserted into the power connector 1 through the limiting and guiding structure. Otherwise, it cannot be inserted, thus avoiding the problem of incorrect connection of the positive and negative poles. Such a design makes the installation process more intuitive and simple, and also improves the reliability of the connector. Specifically, when implemented, in order to facilitate installation and achieve a good waterproof effect at the same time, the power connector 1 is made of a transparent material to facilitate observing the internal connection situation. The material of the power connector 1 is preferably made of polycarbonate or acrylic resin material with good water resistance and weather resistance. A sealing structure is provided on the power connector 1 and the strip connection base 2 to ensure good waterproof performance under extreme conditions.

[0027] Specifically, as Figures 1 - 3As shown in the figure, the limit guiding structure of this case includes a first slide rail 22 provided on the outer wall of the light strip connector seat 2, and a first chute 12 which is provided on the inner wall of the power supply connector 1 and is adapted to the structure of the first slide rail 22 for the first slide rail 22 to be inserted into. It should be noted that the first slide rail 22 is adapted to the first chute 12, that is, they have the same size and dimensions and matching structures, so that the first slide rail 22 can closely fit and slide in the first chute 12. Through the cooperation of the first slide rail 22 and the first chute 12, the installation process between the light strip connector 2 and the power supply connector 1 becomes very simple and fast. Users can complete the installation of the connector without complex operation steps, improving work efficiency. At the same time, it effectively avoids the problem of wrong connection of positive and negative poles and improves the connection accuracy.

[0028] As Figures 1 - 3 shown, as a preferred embodiment of this case, on the basis of the above, the limit guiding structure further includes a second slide rail 23 provided on the outer wall of the light strip connector seat 2, and a second chute 13 which is provided on the inner wall of the power supply connector 1 and is adapted to the structure of the second slide rail 23 for the second slide rail 23 to be inserted into. The groove width of the second chute 13 is greater than or less than that of the first chute 12. In this embodiment, the first chute 12 and the second chute 13 are respectively provided on the opposite side walls of the power supply connector 1. That is to say, when the first chute 12 is provided on the upper inner wall of the power supply connector 1, the second chute 13 needs to be provided on the lower inner wall of the power supply connector 1. Two sets of limit guiding structures are symmetrically arranged, which can make the power supply connector 1 and the light strip connector 2 easier to align and insert, thus facilitating installation and disassembly. At the same time, the contact between the power supply connector 1 and the light strip connector 2 is more uniform, thereby improving their connection stability and reliability. It should be noted that the sizes of the first chute 12 and the second chute 13 are different, that is, the groove width of the second chute 13 is greater than or less than that of the first chute 12, so as to facilitate users to correctly distinguish the positive and negative poles. At this time, the first slide rail 22 and the second slide rail 23 need to be correspondingly arranged. In different application scenarios, users can also set more limit guiding structures according to needs.

[0029] During specific implementation, the sealing structure includes a waterproof rubber ring provided at the upper ends of the light strip connector seat 2 and the power supply connector 1. The waterproof rubber ring can be integrally formed from materials such as flexible rubber, silica gel, and polyurethane with good waterproof effect, and is provided at the gap of the connection through interference fit at the upper ends of the light strip connector seat 2 and the power supply connector 1. It can also be sealed by manual caulking, that is, caulking is performed after the two are connected. This sealing method has relatively better sealing performance and waterproof performance. The type of waterproof glue can be selected according to actual needs, such as silicone sealant, etc. This case preferably uses an interference-fit waterproof rubber ring to save processes and at the same time facilitate the disassembly, replacement, and maintenance between the two.

[0030] Furthermore, as Figure 3 、Figure 4 As shown, the light strip connection base 2 includes a base 201 and a cover 202 hinged to one end of the base 201. The other end of the cover 202 is fastened to the base 201 through a snap structure. This structure simplifies the installation process. Since the cover 202 is pivotally connected to the base 201 through a hinge, the light strip connection base 2 can be quickly opened and closed without using tools, which simplifies the installation process of the light strip 3. At the same time, the light strip connection base 2 can be easily opened and closed for maintenance or component replacement, improving the maintainability. As Figure 3 shown, when the light strip connection base 2 includes a base 201 and a cover 202, the first slide rail 22 can be the hinge connection part of the base 201 and the cover 202. At this time, the second slide rail 23 is the track formed by the side wall where the base 201 and the cover 202 are fastened through the snap connection structure.

[0031] Specifically, as Figure 4 shown, the snap structure includes a snap block 2011 provided on the base 201 and a slot 2021 opened on the side wall of the cover 202 for the snap block 2011 to snap into. In specific implementation, one, two or more snap blocks 2011 can be provided, and the number of slots 2021 can be set according to the number of snap blocks 2011. To make the snap connection between the base 201 and the cover 202 stable and convenient for disassembly, preferably in this case, one snap block 2011 and one slot 2021 are respectively provided. The snap structure provided for the light strip connection base 2 in this case is convenient for disassembly and assembly. The light strip connection base 2 is usually made of an insulating and flexible material, such as polycarbonate, etc.

[0032] Referring to Figure 4 shown, further, a plurality of protrusions 2022 are uniformly arranged on the inner wall of the upper end of the cover 202, and the protrusions 2022 extend downward along the inner wall of the upper end of the cover 202 to form a conical shape. That is to say, the protrusions 2022 are arranged on the inner wall of the upper end of the cover 202, presenting a conical or similar conical structure, with a relatively sharp top and a relatively wide bottom. After the light strip 3 is installed, the protrusions 2022 are usually perpendicular to the contact surface of the light strip 3. When the cover 202 is pressed downward to be snap-connected to the base 201, the light strip 3 can be pressed into the light strip connection base 2, so that the connection between the light strip 3 and the light strip connection base 2 is more stable, effectively avoiding the problem of poor contact between the two due to vibration or movement of the light strip 3 or the light strip connection base 2. A plurality of protrusions 2022 are uniformly arranged. In specific implementation, the number of protrusions 2022 can be set according to the size of the light strip 3 to ensure that the cover 202 can exert sufficient contact pressure on the light strip 3 and increase the friction between the two.

[0033] Referring to Figure 4As shown in the figure, further, a slot 2012 for inserting the LED strip 3 is provided on the base 201. A guide rail 2013 with an upward protrusion 2022 is provided at the bottom of the slot 2012. The guide rail 2013 includes a ramp end 20131 that facilitates the insertion of the LED strip 3. By extending the guide rail 2013 with a ramp end 20131 upward at the bottom of the slot 2012, when installing the LED strip 3, the LED strip 3 can smoothly slide into the slot 2012, so as to accurately connect the LED strip 3 with the second positive and negative conductive pins 21, avoiding the situation where the second positive and negative conductive pins 21 are bent or broken due to incorrect installation of the LED strip 3. At the same time, it is ensured that the LED strip will not shift or twist during the insertion process, and can be more accurately and quickly connected with the second positive and negative conductive pins 21, effectively avoiding the situation of reverse connection of positive and negative poles.

[0034] Referring to Figure 4 , specifically, one end of the second positive and negative conductive pins 21 extends out of the base 201 to facilitate plugging and mating with the first positive and negative conductive pins 11 in the power connector 1 to achieve electrical connection. The other end of the second positive and negative conductive pins 21 extends into the slot 2012 to facilitate plugging and mating with the third positive and negative conductive pins 31 provided on the LED strip 3 to achieve electrical connection.

[0035] As described above, the present case protects a waterproof LED strip connector, and all technical solutions identical or similar to the present case should be regarded as falling within the protection scope of the present case.
