Description

Technical Field

[0001] This utility model belongs to the field of light strip technology, and in particular relates to a light strip connector. Background Technology

[0002] Liquid crystal displays (LCDs) typically consist of an LCD panel and a backlight module. The LCD panel and backlight module are positioned opposite each other, with the backlight module providing the light source to the LCD panel to display images. Due to the advantages of LEDs, such as low power consumption, long lifespan, excellent color reproduction characteristics, and high contrast, LED strips are mainly used as the backlight source in the backlight module of current LCDs.

[0003] Most LED light strips are electrically connected to the PCB board via soldering or connector mating. Soldering involves directly fixing the light strip's wires to corresponding solder points on the PCB, providing stable electrical contact but making disassembly inconvenient and prone to damaging the light strip or PCB. Connector mating uses male / female connectors on the light strip and corresponding male / female connectors on the PCB, allowing for quick and easy electrical connection. Connectors typically have conductive terminal pins soldered to the PCB for mounting. Since the conductive terminals are usually located on the same side of the connector, external forces can cause the connector to loosen, leading to poor contact between the light strip and the PCB, resulting in unstable brightness or even failure to light up, thus reducing the quality of the light strip. Furthermore, requiring a separate connector for the light strip and PCB increases production costs and assembly complexity. Utility Model Content

[0004] The purpose of this utility model is to provide a light strip connector that solves the problems of existing light strip connectors that are soldered to the PCB board with pins, which are prone to loosening due to external forces, affecting the normal operation of the light strip and resulting in low quality of the light strip; and the need for a connector to connect the light strip and the PCB, which increases production costs and assembly processes.

[0005] To achieve the above objectives, this utility model provides a light strip connector for soldering onto a PCB board and electrically connecting a light strip. It includes a housing with a mounting groove on its outer side wall; a soldering component including an L-shaped connecting portion and a solder foot, the connecting portion being fixed within the mounting groove, and the solder foot being used for soldering and fixing onto the PCB board; and multiple terminals, one end of which extends to the outside of the housing to form a soldering portion, and the other end being fixed inside the housing. The soldering component and the terminals are located on different sides of the housing. The housing has a slot on the side opposite the soldering portion for inserting the light strip. One end of each terminal located inside the housing also has an elastic arm extending into the slot, and the elastic arm is electrically connected to the conductive area of ​​the light strip.

[0006] Furthermore, the mounting groove is a T-shaped groove structure that penetrates the top and bottom surfaces of the housing. The narrow end of the T-shaped groove is an open structure, and a stepped support surface is formed at the bottom of the mounting groove. The lateral length of the connecting part along the side wall of the housing is greater than the lateral length of the weld leg. The welded part is inserted into the mounting groove, the lower surface of the connecting part abuts against the stepped support surface, the free end of the weld leg extends out of the opening, and the bottom surface of the weld leg is lower than the bottom surface of the housing.

[0007] Furthermore, protrusions are provided on both sides of the connecting part to ensure an interference fit between the welded part and the mounting groove.

[0008] Furthermore, the bottom of the welded component is bent upwards to form the weld leg, and the welded component is made of metal.

[0009] Furthermore, the bottom surface of the housing is provided with a downwardly extending positioning protrusion, and one end of the PCB board is provided with a positioning groove that runs vertically through the PCB board. The shape of the positioning protrusion is adapted to the positioning groove.

[0010] Furthermore, the cross-sectional dimension of the positioning protrusion is smaller than the cross-sectional dimension of the housing, and the bottom surface height of the weld foot and the welded part is higher than the bottom surface of the positioning protrusion.

[0011] Furthermore, the slot extends into the positioning protrusion, the bottom surface of the slot has an upwardly extending locking block along the side wall, and the light strip has a corresponding locking groove.

[0012] The above-mentioned technical solutions of one or more technical solutions in the light bar connector provided in this embodiment of the utility model have at least the following technical effects:

[0013] The outer side of the housing features multiple soldering sections for soldering to the PCB board and for electrical connections. A mounting groove on the outer wall of the housing houses the connecting parts for the soldered components, whose solder feet can be soldered onto the PCB board. By providing soldering sections and solder feet, the contact area between the connector and the PCB board is increased, enhancing connection stability. Furthermore, the soldering sections and solder feet are located on different sides of the housing, allowing the connector to be soldered and fixed to the PCB board at different positions, forming multi-point fixation and further enhancing the connector's stability to prevent loosening and detachment, ensuring stable electrical contact and improving the quality of the light strip. Additionally, slots in the housing are used for inserting the light strip, facilitating installation, disassembly, and replacement. Terminals located inside the housing have elastic arms extending into the slots, which are electrically connected to the conductive area of ​​the light strip, ensuring electrical contact between the connector and the light strip. Achieving electrical conductivity between the light strip and the PCB board through a single connector reduces production costs and assembly processes. Attached Figure Description

[0029] In one embodiment of the LED strip connector of this utility model, please refer to... Figures 1 to 7A light strip connector 100, used for soldering onto a PCB board 200 and electrically connecting to a light strip 300, includes a housing 110, the outer wall of which has a mounting groove 112. A soldering component 120 includes an L-shaped connecting portion 122 and a solder foot 121. The connecting portion 122 is fixed within the mounting groove 112, and the solder foot 121 is used for soldering and fixing to the PCB board 200. Multiple terminals 130 have one end extending to the outside of the housing 110 to form a soldering portion 131, and the other end fixed within the housing 110. The soldering component 120 and the terminals 130 are located on different sides of the housing 110. A slot 111 is provided on the side of the housing 110 opposite the soldering portion 131 for inserting the light strip 300. One end of the terminal 130 located within the housing also has a resilient arm 132 extending into the slot 111, and the resilient arm 132 is electrically connected to the conductive area 320 of the light strip.

[0030] Specifically, the outer side of the housing 110 is provided with welding portions 131 of multiple terminals 130 for welding to the PCB board 200 and for electrical connection; the mounting groove 112 on the outer wall of the housing 110 is fixed with a connecting portion 122 of the welding component, and the solder feet 121 of the welding component 120 can be welded to the PCB board 200. By setting the welding portions 131 and solder feet 121, the welding contact area between the connector 100 and the PCB board 200 is increased to enhance the connection stability; and the welding portions 131 and solder feet 121 are located on different sides of the housing 110, so that the connector 100 and the PCB board 200 are welded and fixed at different positions, forming multi-point fixation, further enhancing the stability of the connector 100 to prevent loosening and falling off, ensuring stable electrical contact, and improving the quality of the light strip. In addition, the slot 111 of the housing is used to insert and fix the light strip 300, which facilitates installation, disassembly and replacement; the terminal 130 located inside the housing has a flexible arm 132 extending into the slot 111. The flexible arm 132 is electrically connected to the conductive area 320 of the light strip, and the flexible arm 132 ensures electrical contact between the connector 100 and the light strip 300. Electrical conduction between the light strip 300 and the PCB board 200 is achieved through a single connector 100, which reduces production costs and assembly processes.

[0031] Preferably, there are at least two welded parts 120, which are respectively provided on two opposite sides of the housing 110. Specifically, since multiple welded parts 120 are respectively provided on two opposite sides of the housing 110, the welding part 131 of the terminal and the welded parts 120 are located on different sides of the housing 110, so that the housing 110 is circumferentially welded and fixed on the PCB board 200, ensuring the stability of the connection and not easily loosened by external forces.

[0032] For further details, please refer to... Figure 6 and Figure 7The mounting groove 112 is a T-shaped groove structure that penetrates the top and bottom surfaces of the housing 110. The narrow end of the T-shaped groove is an opening 113, and a stepped support surface 114 is formed at the bottom of the mounting groove 112. The lateral length of the connecting part 122 along the side wall of the housing 110 is greater than the lateral length of the weld leg 121. The welded part 120 is inserted into the mounting groove 112, the lower surface of the connecting part 122 abuts against the stepped support surface 114, the free end of the weld leg 121 extends out of the opening 113, and the bottom surface of the weld leg is lower than and located at the bottom of the housing 110. Specifically, when assembling the welded part 120 into the mounting groove 112, the weld leg first slides into the narrow end opening 113 of the T-shaped groove and the free end extends out of the housing 110. The welded part 120 is then pressed down so that the connecting part 122 is inserted into the wide end of the T-shaped groove until the lower surface of the connecting part 122 abuts against the stepped support surface 114, thus completing the assembly and fixation of the welded part 120. After assembly, the bottom surface of solder foot 121 is lower than the bottom surface of housing 110, which makes the contact between solder foot 121 and PCB board 200 more complete and facilitates soldering.

[0033] For further details, please refer to... Figure 7 The connecting portion 122 has protrusions 123 on both sides, allowing the welded part 120 to have an interference fit with the mounting groove 112. Specifically, the interference fit ensures that the welded part 120 and the mounting groove 112 are firmly assembled, improving the stability of the welded part 120 and the housing 110. Preferably, the bottom surface of the protrusion 123 is a guide slope 124, and the top surface and the side wall of the connecting portion 122 have an inwardly concave arc transition surface 125. Specifically, the guide slope 124 reduces the installation resistance of the connecting portion 122, and the arc transition surface 125 reduces stress concentration.

[0034] For further details, please refer to... Figure 7 The bottom of the welded component 120 is bent upwards to form a weld leg 121. The welded component 120 is made of metal. Specifically, the metal welded component 120 has good structural strength. The weld leg 121 is formed by bending, which simplifies the production process and enhances the strength of the welded component 120.

[0035] For further details, please refer to... Figure 2 and Figure 3 The bottom surface of the housing 110 is also provided with a downwardly extending positioning protrusion 115, and one end of the PCB board 200 is provided with a vertically penetrating positioning groove 210. The shape of the positioning protrusion 115 is adapted to the positioning groove 210. Specifically, the positioning protrusion 115 is installed in the positioning groove 210 to achieve physical positioning of the connector 100 and the PCB board 200, thereby enhancing the stability of the connector 100. It also reduces the vertical space occupied by the connector 100, making the assembly of the connector 100 and the PCB board 200 thinner. In addition, one side of the positioning groove 210 is open, and the opening of the positioning groove 210 corresponds to the opening direction of the slot 111 to prevent interference with the insertion of the light strip 300 into the slot 111.

[0036] For further details, please refer to... Figures 1 to 3 The cross-sectional dimension of the positioning protrusion 115 is smaller than that of the housing 110, and the bottom surface height of the solder feet 121 and the solder part 131 is higher than the bottom surface of the positioning protrusion 115. Specifically, the positioning groove 210 constrains the positioning protrusion 115 of the positioning connector without affecting the solder feet 121 and the solder part 131 located on the outer periphery of the upper housing and their soldering to the PCB board 200.

[0037] Preferably, please refer to Figure 3 The housing 110 has a welded part 120, and the side dimension of the welded part 131 is larger than the dimension of the positioning protrusion 115 on the same side. The bottom surface of the weld foot 121 is flush with the bottom surface of the welded part 131. Specifically, the positioning protrusion 115 is smaller in size to avoid the weld foot 121 and the welded part 131, so as not to affect the welding. The bottom surface of the weld foot 121 is flush with the bottom surface of the welded part 131 to prevent the difference in height between the two welding positions from affecting the welding effect and to ensure the stability of the connection.

[0038] For further details, please refer to... Figure 2 and Figure 5 The slot 111 extends into the positioning protrusion 115. The bottom surface of the slot 111 has an upwardly extending locking block 116 along its side wall, and the light strip 300 has a corresponding locking groove 310. Specifically, after the light strip 300 is inserted into the slot 111, the locking block 116 engages with the locking groove 310 to prevent the light strip 300 from becoming loose. The elastic arm 132 abuts against the conductive area of ​​the light strip 300, ensuring a stable electrical connection between the conductive area of ​​the light strip 300 and the elastic arm 132.

[0039] Preferably, the conductive area of ​​the lamp strip 300 is provided with multiple metal contact strips, and each metal contact strip corresponds one-to-one with the elastic arm 132 of the terminal. The metal contact strips are made by tin spraying or gold plating.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
