Description

Technical Field

[0001] This utility model relates to the field of COB light strip technology, and more specifically, to a COB light strip with a prefabricated connector. Background Technology

[0002] In the field of LED lighting, COB LED strips have been widely used in home decoration, commercial lighting, and industrial lighting due to their advantages such as high brightness, uniform light emission, and small size. However, the traditional connection methods for COB LED strips still have many technical bottlenecks that need to be solved.

[0003] Currently, the mainstream COB LED strip connection technology on the market mainly adopts a fixed connector solution. This type of design has revealed obvious limitations in practical applications: First, fixed-angle connectors cannot adapt to complex installation environments. When corner wiring is required, it often leads to excessive bending of the wire harness, which can easily cause wire breakage or poor contact after long-term use.

[0004] Secondly, existing protective measures are mostly simple rubber sleeves, which are not only unsightly but also fail to provide effective dust and water protection. They are also prone to circuit failure in humid or dusty environments. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a COB light strip with a prefabricated connector to solve the problems in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution; A COB light strip with a prefabricated connector includes a light strip body and a male connector connected to its end. The male connector has a mounting groove on the side away from the light strip body. A female connector is provided inside the mounting groove. The female connector has a connecting end for communicating with the inside of the male connector. The mounting groove has two through holes on its inner wall. The female connector has two inner grooves on both sides. A spring is fixedly installed on the inner wall of the inner groove. The other end of the spring passes through the inner groove and is connected to a damping plate. A pressing rod is fixedly connected to the damping plate. The end of the pressing rod away from the spring passes through the through hole and extends to the outside of the male connector. The other end of the pressing rod passes through the damping plate and extends into the inner groove. A guide shaft is fixedly installed on the inner wall of the inner groove. The guide shaft is located inside the spring. The pressing rod is slidably connected to the guide shaft.

[0007] As a further description of the above technical solution: a damping pad is fixedly connected to the damping plate, and the damping pad is in contact with the inner wall of the mounting groove.

[0008] As a further description of the above technical solution: a rubber protrusion is connected to the inner wall of the mounting groove, and the rubber protrusion is located on the right side of the connecting female head and plays a limiting role.

[0009] As a further description of the above technical solution: a protective cover is slidably connected to the outer side of the male connector. The protective cover is composed of two parts that are snapped together. The protective cover shields and protects the connection position between the light strip body and the male connector.

[0010] As a further description of the above technical solution: a limiting groove is provided on the outer side of the male connector, and a slider is provided on the inner side of the protective cover. The slider is used in conjunction with the limiting groove, and a limiting block is connected to the inner wall of the limiting groove. The limiting block is made of rubber material.

[0011] Compared with existing technologies, the advantages of this utility model are: This utility model allows the connector to connect to COB LED strips without requiring subsequent connections, reducing operational steps. At the same time, the push-to-unlock mechanism and spring damping system enable stepless angle adjustment of the female connector, solving the problem of wire harness bending caused by traditional fixed connectors. It can also flexibly adjust the wiring angle according to the actual installation environment, so that the LED strip can maintain the best installation state in various complex scenarios. Secondly, the protective cover, which adopts a split-type snap-fit ​​structure, achieves a self-locking function through the cooperation of the limiting groove and the rubber limiting block, which not only ensures the firm protection of the connection parts, but also allows for easy disassembly and maintenance.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] To address the issue that previous CBO LED strip connectors could not handle different angles when connecting to wire harnesses, leading to easy bending and damage of the wire harness, this solution provides Example 1: Please see Figures 1-4 In this utility model, a COB light strip with a prefabricated connector includes a light strip body 1 and a male connector 2 connected to its end. The male connector 2 has a mounting groove 201 on the side away from the light strip body 1. A female connector 3 is provided inside the mounting groove 201. The female connector 3 has a connecting end 301 for communicating with the inside of the male connector 2.

[0016] Two through holes 202 are provided on the inner wall of the mounting groove 201. Two inner grooves 302 are provided on both sides of the connecting female head 3. A spring 4 is fixedly installed on the inner wall of the inner groove 302. The other end of the spring 4 passes through the inner groove 302 and is connected to a damping plate 5. A pressing rod 6 is fixedly connected to the damping plate 5. The end of the pressing rod 6 away from the spring 4 passes through the through hole 202 and extends to the outside of the connecting male head 2. The other end of the pressing rod 6 passes through the damping plate 5 and extends into the inner groove 302. A guide shaft 7 is fixedly installed on the inner wall of the inner groove 302. The guide shaft 7 is located inside the spring 4. The pressing rod 6 is slidably connected to the guide shaft 7.

[0017] A damping pad 501 is fixedly connected to the damping plate 5, and the damping pad 501 is in contact with the inner wall of the mounting groove 201. In this utility model, the male connector 2 and the main body of the light strip adopt a prefabricated integrated design to ensure the stability of the electrical connection. When it is necessary to connect an external wire harness, the user wire harness is inserted into the connector 301 and then extended into the interior until it is connected to the inside of the male connector 2. Locking is achieved by pressing the existing common aluminum sheet.

[0018] If the angle of the wiring harness needs to be adjusted, the user only needs to press the pressing rods 6 on both sides of the male connector 2 to push the damping plate 5 to compress the spring 4, so that the damping pad 501 separates from the inner wall of the mounting groove 201. At this time, the female connector 3 can rotate freely to adapt to different wiring scenarios such as corner bends and curved surface installations. After releasing the pressing rods 6, the spring 4 returns to its original position, and the damping pad 501 presses against the inner wall of the mounting groove 201 again to form a stable friction lock, ensuring that the angle will not shift due to vibration or pulling after it is fixed.

[0019] Please see Figure 1 and 2 Among them, a rubber protrusion 8 is connected to the inner wall of the mounting groove 201. The rubber protrusion 8 is located on the right side of the connecting female head 3 and plays a limiting role.

[0020] In this invention, during the rotation of the female connector 3, the rubber protrusion 8 can play a limiting role, preventing damage to the wire harness caused by excessive rotation angle.

[0021] Based on the above embodiment one, in order to protect the connection position between the light strip and the connector, this solution provides embodiment two: Please see Figure 1 and 2 The male connector 2 is slidably connected to a protective cover 9, which is composed of two parts that are snapped together. The protective cover 9 shields and protects the connection position between the light strip body 1 and the male connector 2. A limiting groove 203 is opened on the outer side of the male connector 2, and a slider 901 is opened on the inner side of the protective cover 9. The slider 901 is used in conjunction with the limiting groove 203. A limiting block 204 is connected to the inner wall of the limiting groove 203. The limiting block 204 is made of rubber material.

[0022] In this utility model, based on the adjustable angle connection structure, this solution further integrates a protective cover 9 to improve the overall protection performance. The protective cover 9 adopts an upper and lower split snap-fit ​​design. The user can slide it to the designated position along the limiting groove 203 on the outside of the connecting male 2 to completely cover the joint between the light strip body 1 and the connecting male 2.

[0023] The slider 901 of the protective cover 9 cooperates with the rubber limit block 204 in the limit groove 203 to form a self-locking mechanism. When sliding, a little force is required to make the limit block 204 elastically deform. After passing the critical point, it can be locked to prevent the protective cover 9 from falling off due to vibration or pulling. When it needs to be disassembled, reverse force can be applied to easily separate it, which is convenient for later maintenance.

[0024] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
