Description

Technical Field

[0001] This application relates to the field of LED strip connection technology, and in particular to a connector for connecting LED strip substrates. Background Technology

[0002] LED light strips refer to LEDs assembled on a strip of flexible circuit board. In daily use, LED light strips are often either too short or too long, requiring the LED light strip substrate to be extended or cut to meet the needs.

[0003] Currently, the most common method for directly connecting different LED strip substrates is a snap-fit ​​connection. This method consists of an insulating shell and an internal metal spring. The connection is stabilized by the friction between the internal metal spring and the contacts on the LED strip. However, these metal springs are prone to loosening over long-term use, affecting conductivity stability and the lifespan of the LED strip.

[0004] Another invention patent, CN118099847A, discloses a pluggable adjustable LED strip quick connector and an LED strip. It achieves connection between different LED strips by setting up a pluggable assembly, a spring-loaded engagement mechanism, and other structures. However, the connector structure in this technical solution is very complex, and there is a risk of spring failure and wear of the engagement mechanism after long-term use, affecting the long-term reliability of the connection.

[0006] This application provides a connector for connecting light strip substrates, which is used to install and fix two light strip substrates so that the two light strips are electrically connected to each other. The connector is a U-shaped groove structure formed by integral stamping and bending of a metal plate, including a horizontally extending inner bottom and two side walls formed by bending vertically upward from the left and right edges of the inner bottom. At the top of each sidewall, a limiting plate protruding horizontally inward is formed by stamping process. At least two limiting plates are provided on each sidewall, and a guide slope formed by stamping is provided on the limiting plate. The inner edge of the limiting plate, the inner side of the corresponding side wall, and the upper surface of the inner bottom together form a fixing groove for inserting and fixing the light strip. The width of the fixing slot matches the width of the light strip, and the height of the fixing slot matches the thickness of the two light strips, so that the light strip is inserted in a direction perpendicular to the side wall and is tightly locked between the limiting plate and the inner bottom. The top front end of the light strip is equipped with multiple top conductive contacts, and the bottom tail end of the light strip is equipped with multiple bottom conductive strips. The two light strips are electrically connected by contacting each other through the conductive contacts and conductive strips.

[0020] LED light strips refer to LEDs assembled on a strip of flexible circuit board. In daily use, LED light strips are often either too short or too long, requiring the LED light strip substrate to be extended or cut to meet the needs.

[0021] Currently, the most common method for directly connecting different LED strip substrates is a snap-fit ​​connection. This method consists of an insulating shell and an internal metal spring. The connection is stabilized by the friction between the internal metal spring and the contacts on the LED strip. However, these metal springs are prone to loosening over long-term use, affecting conductivity stability and the lifespan of the LED strip.

[0022] Another invention patent, CN118099847A, discloses a pluggable adjustable LED strip quick connector and an LED strip. It achieves connection between different LED strips by setting up a pluggable assembly, a spring-loaded engagement mechanism, and other structures. However, the connector structure in this technical solution is very complex, and there is a risk of spring failure and wear of the engagement mechanism after long-term use, affecting the long-term reliability of the connection.

[0023] To address the aforementioned issues, this application provides a connector for connecting LED strip substrates, which enables electrical conductivity between two LED strips and ensures connection stability during long-term use.

[0024] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0025] Figure 1 This is a schematic diagram of an overall structure of the connector in an embodiment of this application; Figure 2 This is a side view of the connecting seat in an embodiment of this application; Figure 3 This is a top view of the connecting seat in an embodiment of this application.

[0026] See Figure 1-3 A connector for connecting LED strip substrates, the connector being used to mount and fix two LED strip substrates so that the two LED strips are electrically connected to each other.

[0027] The connector is a U-shaped groove structure formed by integral stamping and bending of a metal plate, including a horizontally extending inner bottom 1 and two side walls 2 formed by bending vertically upward from the left and right edges of the inner bottom 1.

[0028] On the upper part of each sidewall 2, a limiting plate 3 protruding horizontally inward is formed by stamping process. At least two limiting plates 3 are provided on each sidewall 2, and a guide slope 301 formed by stamping is provided on the limiting plate 3.

[0029] The inner edge of the limiting plate 3, the inner side of the corresponding side wall 2, and the upper surface of the inner bottom 1 together form a fixing groove 4 for inserting and fixing the light strip.

[0030] The width of the fixing slot 4 matches the width of the light strip, and the height of the fixing slot 4 matches the thickness of the two light strips, so that the light strip is inserted in a direction perpendicular to the side wall 2 and is tightly locked between the limiting plate 3 and the inner bottom 1.

[0031] In this embodiment, the limiting plate 3 with the guide slope 301 is formed by stamping, which can "guide" the light strip to the fixing slot 4 and fix it in the middle during the installation of the light strip, making the installation more convenient.

[0032] The top front end of the light strip is equipped with multiple top conductive contacts, and the bottom tail end of the light strip is equipped with multiple bottom conductive strips. The two light strips are electrically connected by contacting each other through the conductive contacts and the bottom conductive strips.

[0033] In this embodiment, the connector has a simple structure and is easy to install and use. After the two light strip substrates are installed into the fixing slot 4 one after the other, the top light strip will be clamped onto the bottom light strip. The bottom conductive strip at the bottom end of the top light strip and the conductive contact at the bottom end of the top light strip are tightly pressed together in the fixing slot 4 to form an electrical connection, so that the two light strips can make contact with each other to achieve electrical conduction. At the same time, the connector of this application is a one-piece molded metal part with sufficient structural rigidity. It is not easily deformed under long-term use or slight vibration, and can maintain a stable pressing force for a long time, ensuring the connection stability for long-term use.

[0034] Specifically: the length of the connector is 20mm, and two limiting plates 3 are provided on each side wall 2; the width of the limiting plate 3 is 4mm, and the center distance between the two limiting plates 3 on the same side wall 2 is 8mm.

[0035] In this embodiment, the length of the connector is set to 20mm, which can provide suitable installation space. Two limiting plates 3 are set on each side wall 2, which can provide a stable clamping force for fixing the light strip.

[0036] Specifically: The inner bottom 1 surface of the connector is covered with an insulating layer to prevent short circuit between the light strip and the connector.

[0037] In this embodiment, by covering the inner bottom 1 surface of the connector with an insulating layer, it is possible to effectively prevent short circuits between the bottom insulating layer of the light strip and the metal connector after the insulation layer is damaged, thereby improving safety.

[0038] Specifically: the two ends of the sidewall 2 are rounded.

[0039] In this embodiment, by rounding the corners at both ends of the sidewall 2, it is possible to prevent the sides of the light strip or the contacts from being scratched by sharp right angles, and to effectively prevent operators from being cut.

[0040] Specifically: The connector is formed by integral stamping and bending of a stainless steel plate.

[0041] In this embodiment, the connecting seat structure is simple, suitable for mass production by stamping and bending stainless steel plates, with good consistency and controllable cost.

[0042] The technical solutions provided in this application have the following beneficial effects: The connector of this application has a simple structure and is easy to install and use. After two light strips are installed into the fixing slot one after the other, the top light strip is clamped onto the bottom light strip. The bottom conductive strip at the bottom end of the top light strip and the conductive contact at the bottom end of the top light strip are tightly pressed together in the fixing slot to form an electrical connection, so that the two light strips can make contact with each other to achieve electrical conduction. At the same time, the connector of this application is a one-piece molded metal part with sufficient structural rigidity. It is not easily deformed under long-term use or slight vibration, and can maintain a stable pressing force for a long time, ensuring the connection stability for long-term use.
