Description

Technical Field

[0001] This application relates to the field of LED strip connection technology, and more particularly to an LED strip connector. Background Technology

[0002] LED light strips refer to LEDs assembled on a strip of flexible circuit board. In daily use, to ensure the safety of the light strip, it is often necessary to perform secondary encapsulation. This involves first covering the flexible circuit board, LED chips, current-limiting resistors, and wires with waterproof glue, and then tightly wrapping the entire flexible LED light strip with a flexible transparent sleeve to form a complete LED light strip.

[0003] Currently, for scenarios requiring long-distance use of LED light strips, the connection between different LED light strips is often achieved by directly setting connection terminals on the LED light strips. For example, invention patent with publication number CN103398317B discloses: a high-voltage flexible LED patch light strip, its manufacturing process, and its installation method, wherein the front and rear ends of the light strip unit are fitted with end caps, and one or more light strip units can be connected front and rear through connecting parts that match the end caps.

[0004] However, this method of directly setting the connection terminals on the LED light strip requires soldering the connection terminals to both ends of the light strip during the production of the light strip, which will generate many additional processes. The production difficulty when sealing the light strip is relatively large, resulting in higher manufacturing costs. At the same time, during the installation process, when the LED light strip is bent, swayed or pulled by external forces, the solder joints are prone to falling off, affecting normal use. Utility Model Content

[0005] To solve or partially solve the problems existing in the related technologies, this application provides a light strip connector that can avoid the problem of "solder joint detachment" caused by vibration, bending or pulling during installation, and effectively ensure the connection stability between the light strip connector and the LED light strip.

[0006] This application provides a light strip connector for use with LED light strips. The LED light strip has power slots on both sides for inserting the light strip connector to supply power. The LED strip connector includes: a first housing, the width and height of which correspond to the outer shell size of the LED strip; two wires are provided in the first housing, and slot terminals are respectively connected to the wires; a slot fixing block is provided at the front end of the first housing, located directly above the slot terminals. The slot terminal and the slot fixing block form a slot connector corresponding to the power connection slot. The size of the slot connector corresponds to the size of the power connection slot. After the slot connector is inserted into the power connection slot, the LED substrate in the power connection slot is locked between the slot terminal and the slot fixing block, and the slot terminal is in close contact with the conductive plate at the bottom of the LED substrate. The bottom of the slot fixing block is recessed inward to form a fixing clearance groove. The size of the fixing clearance groove corresponds to the size of the LED beads on the LED substrate, so as to avoid and position the LED beads after the slot connector is inserted. The LED strip connector also includes a fixed housing, on the side wall of which a fixing groove is provided for clamping the first housing and the LED strip.

[0007] Optionally, in some embodiments of this application: The first housing is provided with first limiting grooves on the upper and lower sides; The LED light strip has second limiting grooves on the upper and lower sides of its outer shell; The fixed housing has limit protrusions on the upper and lower sides of its outer shell; The limiting protrusion on the fixed housing simultaneously engages with the first limiting groove of the first housing and the second limiting groove on the LED strip housing, thereby locking and fixing the fixed housing, the first housing, and the LED strip in a direction perpendicular to the insertion direction and the length of the strip.

[0008] Optionally, in some embodiments of this application: The front end of the slot terminal is narrowed, and both ends are chamfered to form a terminal guide bevel.

[0009] Optionally, in some embodiments of this application: The front end of the slot fixing block is narrowed and both ends are chamfered to form a guide slope for the fixing block.

[0010] Optionally, in some embodiments of this application: The first housing is injection molded as a single piece.

[0011] The technical solution provided in this application may include the following beneficial effects: This application uses a slot connector composed of slot terminals and slot fixing blocks to hold the LED substrate in the power connection slot between the slot terminals and the slot fixing blocks. The slot terminals are in close contact with the conductive plate at the bottom of the LED substrate. By using mechanical clamping to conduct electricity, electrical connection between the LED strip connector and the LED strip is achieved. The LED strip connector can be installed and powered on after the LED strip is installed, which effectively avoids the problem of "solder joint detachment" caused by vibration, bending or pulling during installation. Furthermore, by setting a fixed housing, the connection stability between the LED strip connector and the LED strip is effectively guaranteed.

[0012] This application, by setting a limiting protrusion on the fixed housing in conjunction with the first limiting groove and the second limiting groove, can rigidly interlock the connector body, the light strip and the external fixed housing in the vertical direction, effectively preventing the connector from accidentally loosening due to swinging or pulling of the light strip during use, and effectively enhancing the connection reliability for long-term use.

[0021] LED light strips refer to LEDs assembled on a strip of flexible circuit board. In daily use, to ensure the safety of the light strip, it is often necessary to perform secondary encapsulation. This involves first covering the flexible circuit board, LED chips, current-limiting resistors, and wires with waterproof glue, and then tightly wrapping the entire flexible LED light strip with a flexible transparent sleeve to form a complete LED light strip.

[0022] Currently, for scenarios requiring long-distance use of LED light strips, the connection between different LED light strips is often achieved by directly setting connection terminals on the LED light strips. For example, invention patent with publication number CN103398317B discloses: a high-voltage flexible LED patch light strip, its manufacturing process, and its installation method, wherein the front and rear ends of the light strip unit are fitted with end caps, and one or more light strip units can be connected front and rear through connecting parts that match the end caps.

[0023] However, this method of directly setting the connection terminals on the LED light strip requires soldering the connection terminals to both ends of the light strip during the production of the light strip, which will generate many additional processes. The production difficulty when sealing the light strip is relatively large, resulting in higher manufacturing costs. At the same time, during the installation process, when the LED light strip is bent, swayed or pulled by external forces, the solder joints are prone to falling off, affecting normal use.

[0024] To address the aforementioned issues, this application provides a light strip connector that avoids the problem of "solder joint detachment" caused by vibration, bending, or pulling during installation, effectively ensuring the connection stability between the light strip connector and the LED light strip.

[0025] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0026] Figure 1 This is a schematic diagram of the internal structure of the LED strip connector in an embodiment of this application; Figure 2 This is a schematic diagram of the external structure of the LED strip connector in an embodiment of this application; Figure 3 This is a schematic diagram of a structure of the first housing in an embodiment of this application; Figure 4 This is a schematic diagram of a slot terminal in an embodiment of this application; Figure 5 This is a schematic diagram of a fixed shell structure in an embodiment of this application; Figure 6 This is a structural schematic diagram of an LED light strip in an embodiment of this application; Figure 7 This is a schematic diagram of an installation structure of the LED strip connector and the LED strip in an embodiment of this application.

[0027] See Figure 1-7 A light strip connector is used in an LED light strip 5. Power connection slots 502 are provided on both sides of the LED light strip 5 for inserting the light strip connector to supply power.

[0028] The LED strip connector includes: a first housing 1, the width and height of which correspond to the outer shell size of the LED strip 5; two wires 101 are disposed in the first housing 1, and slot terminals 2 are respectively connected to the wires 101; a slot fixing block 3 is disposed at the front end of the first housing 1, located directly above the slot terminals 2; and a 2-pin interface terminal is connected to the rear end of the two wires 101.

[0029] The slot terminal 2 and the slot fixing block 3 form a slot connector corresponding to the power connection slot 502. The size of the slot connector corresponds to the size of the power connection slot 502. After the slot connector is inserted into the power connection slot 502, the LED substrate in the power connection slot 502 is locked between the slot terminal 2 and the slot fixing block 3, and the slot terminal 2 is in close contact with the conductive plate at the bottom of the LED substrate.

[0030] The bottom of the slot fixing block 3 is recessed inward to form a fixing clearance groove 301. The size of the fixing clearance groove 301 corresponds to the size of the LED beads on the LED substrate, so as to avoid and position the LED beads after the slot connector is inserted.

[0031] The LED strip connector also includes a fixed housing 4, which has a fixing groove on its side wall for clamping the first housing 1 and the LED strip 5.

[0032] In this embodiment, a slot connector is formed by the slot terminal 2 and the slot fixing block 3. The LED substrate in the power connection slot 502 can be clamped in the middle of the slot terminal 2 and the slot fixing block 3. The slot terminal 2 is close to the conductive plate at the bottom of the LED substrate. By adopting a mechanical clamping and conduction method, the electrical conduction between the LED strip connector and the LED strip is realized. The LED strip connector can be installed and powered on after the LED strip 5 is installed. This effectively avoids the problem of "solder joint detachment" caused by vibration, bending or pulling during installation. In addition, by setting the fixing housing 4, the connection stability between the LED strip connector and the LED strip 5 is effectively guaranteed.

[0033] Secure mechanical locking: The limiting protrusion 401 on the fixed housing 4 simultaneously engages with the grooves of the first housing 1 and the outer shell of the light strip 5, forming a "triple interlocking" structure. This achieves rigid locking in the vertical direction, effectively resisting loosening or falling off caused by external forces, and ensuring mechanical stability for long-term use.

[0034] In this embodiment, by setting a fixed clearance groove 301, space can be provided for the protruding LED beads during the connector insertion process, effectively avoiding damage to the LED beads caused by squeezing and ensuring the normal use of the light strip 5.

[0035] Specifically: the first housing 1 is provided with first limiting grooves 102 on the upper and lower sides; the LED light strip 5 is provided with second limiting grooves 501 on the upper and lower sides; the fixed housing 4 is provided with limiting protrusions 401 on the upper and lower sides. The limiting protrusion 401 on the fixed housing 4 simultaneously engages with the first limiting groove 102 of the first housing 1 and the second limiting groove 501 on the outer shell of the LED light strip 5, thereby locking and fixing the fixed housing 4, the first housing 1 and the LED light strip 5 in a direction perpendicular to the insertion direction and the length of the light strip 5.

[0036] In this embodiment, by providing a limiting protrusion 401 on the fixed housing 4 in conjunction with the first limiting groove 102 and the second limiting groove 501, the connector body, the light strip 5 and the external fixed housing 4 can be rigidly interlocked in the vertical direction, effectively preventing the connector from accidentally loosening due to swinging or pulling of the light strip 5 during use, and effectively enhancing the connection reliability for long-term use.

[0037] Specifically: the front end of the slot terminal 2 is narrowed and both ends are chamfered to form a terminal guide slope 201.

[0038] In this embodiment, by forming a terminal guide slope 201, it is easier to insert it into the bottom of the light strip 5, so that the slot terminal 2 can better fit the conductive plate at the bottom of the light strip 5, reducing the installation difficulty.

[0039] Specifically: the front end of the slot fixing block 3 is narrowed and both ends are chamfered to form the fixing block guide slope 302.

[0040] In this embodiment, by forming a fixed block guide slope 302, it is easy to insert the power connection slot 502, reducing the installation difficulty and improving the ease of operation; it can also avoid scratching the surface of the light strip 5 and ensure the integrity of the light strip 5.

[0041] Specifically: the first housing 1 is injection molded as a single piece.

[0042] In this embodiment, the injection-molded first housing 1 has high overall structural strength, ensuring a stable connection between the wire 101 and the slot terminal 2, which is suitable for mass standardized production and reduces manufacturing costs.

[0043] The technical solutions provided in this application have the following beneficial effects: This application uses a slot connector composed of a slot terminal 2 and a slot fixing block 3 to hold the LED substrate in the power connection slot 502 between the slot terminal 2 and the slot fixing block 3. The slot terminal 2 is in close contact with the conductive plate at the bottom of the LED substrate. By using a mechanical clamping and conduction method, electrical conduction between the LED strip connector and the LED strip is achieved. The LED strip connector can be installed and powered on after the LED strip 5 is installed. This effectively avoids the problem of "solder joint detachment" caused by vibration, bending or pulling during installation. Furthermore, by setting a fixing housing 4, the connection stability between the LED strip connector and the LED strip 5 is effectively guaranteed.

[0044] This application, by setting a limiting protrusion 401 on the fixed housing 4 in conjunction with the first limiting groove 102 and the second limiting groove 501, can rigidly interlock the connector body, the light strip 5 and the external fixed housing 4 in the vertical direction, effectively preventing the connector from accidentally loosening due to swinging or pulling of the light strip 5 during use, and effectively enhancing the connection reliability for long-term use.
