Description

Technical Field

[0001] The present invention relates to the field of LED lighting, and in particular to a multifunctional LED lighting connector. Background Art

[0002] Light strips are now widely used in various lighting applications, including home decoration, commercial displays, and architectural lighting. However, in practical use, connecting light strips has always been a significant technical challenge. Traditionally, two light strips are electrically connected using a plug-in connector. While plug-in connectors ensure electrical connectivity between light strips, they present some significant challenges in practical use.

[0003] First, after a period of use, the plug-in connectors are prone to loosening or disconnection, especially when the light strip is pulled. This not only affects the normal use of the light strip, but can also cause circuit failures, increasing maintenance costs and user risks. To address this issue, some people have designed anti-detachment parts to prevent the two connectors from separating. Although anti-detachment parts can solve the problem of connector loosening to a certain extent, their structure is relatively complex, increasing the manufacturing cost and process difficulty of the connector.

[0004] Furthermore, connectors with anti-detachment features can be inconvenient to disengage. Users must manually locate and remove the connector, which can be difficult in some situations. If the connector is mounted high or in a confined space, access to the connector is difficult, making the disengagement process even more complicated and awkward. This design is particularly inconvenient in applications requiring frequent assembly and disassembly, impacting user experience and efficiency. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a multifunctional LED lighting connector, which can not only ensure a firm connection between the light strips, but also can be remotely separated when needed.

[0011] As a preferred technical solution, a conductive buckle groove is provided on the end face of the conductive contact terminal, and a conductive buckle point is provided at a position corresponding to the conductive buckle groove on the conductive connecting piece. The conductive buckle point is buckled into the conductive buckle groove, and the conductive contact terminal is conductively connected to the conductive connecting piece, and the conductive connecting piece is conductively connected to one end of the flexible cable on the side away from the conductive buckle point. The conductive connecting piece is arranged inside the shell of the second connector.

[0012] As a preferred technical solution, a hinge shaft is respectively provided on both sides of the connector plate, and a hinge ear is respectively provided on both sides of the top of the second connector. A torsion spring is installed on the hinge shaft, and the hinge shaft is elastically hinged in the hinge ear through the torsion spring.

[0031] All features disclosed in this specification, or all steps in the disclosed methods or processes, except mutually exclusive features and / or steps, can be combined in any manner.

[0032] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0033] like Figure 1 and Figure 2 As shown, a multifunctional LED lighting connector of the present invention includes a first connector 1, one end of which is provided with a first connecting light strip 8, and an upper end surface of the first connector 1 has an inclined docking surface 7, and the inclined docking surface 7 is provided with a pin docking hole 20, and the pin docking hole 20 is conductively connected to the first connecting light strip 8;

[0034] It also includes a second connector 2, one end of which is provided with a second connecting light strip 9, a winding chamber is provided in the second connector 2 on a side away from the first connector 1, the top of the winding chamber is provided with an opening window 3, a conductive winding mechanism is provided in the winding chamber, the second connecting light strip 9 is partially wound around the conductive winding mechanism, and the wound second connecting light strip 9 forms a wire winding protrusion 11 in the winding chamber, and the wire winding protrusion 11 passes through the opening window 3 and extends to the upper end surface of the second connector 2;

[0035] like Figure 1 and Figure 7 As shown, it also includes a connector plate 4, both sides of which are elastically hingedly arranged on the upper end surface of the second connector 2, one end of the connector plate 4 extends toward the pin connection hole 20 on the first connector 1, and the bottom of the connector plate 4 is provided with a protruding connection pin 21 corresponding to the position of the pin connection hole 20, and the connector plate 4 is away from the connecting pin 21. The side of the connector plate 4 is in contact with the upper end surface of the wire coil protrusion 11 for support, and the protruding wire coil protrusion 11 is used to make the connector plate 4 elastically rotate along the elastic hinge end, and the connecting pin 21 is inserted into the pin connection hole 20, thereby conductively connecting the first connector 1 and the second connector 2. Therefore, as long as the wire coil protrusion 11 always maintains its size, the connector plate 4 can be kept in a continuously raised state, thereby allowing the connecting pin 21 to remain inserted into the pin connection hole 20, effectively preventing separation. After the second connecting light strip 9 is wound up, one end of the connector plate 4 can provide some supporting pressure after contacting the wire coil protrusion 11, so that one end of the connecting pin 21 can be inserted into the pin connection hole 20 with a certain pressure, and maintain this pressure, so that the connecting pin 21 and the pin connection hole 20 can maintain a tight fit;

[0036] like Figure 3 and Figure 6 As shown, the second connecting light strip 9 is conductively connected to the connecting pin 21 through a flexible flat cable 12. One end of the flexible flat cable 12 is conductively connected to the second connecting light strip 9, and the other end extends into the connector board 4 and is conductively connected to the connecting pin 21. The second connecting light strip 9 and the connector board 4 are kept in a conductive connection state through the flexible flat cable 12.

[0037] Among them, such as Figure 4 and Figure 5 As shown, the conductive winding mechanism includes a winding drum 15, and the second connecting light strip 9 is wound on the winding drum 15, and the conductive end of the second connecting light strip 9 passes through the through groove on the winding drum 15 and extends into the hollow cavity inside the winding drum 15. A sealing sleeve 13 is provided on both sides of the winding drum 15, and the conductive end of the second connecting light strip 9 is connected to a conductive contact terminal 14, and the conductive contact terminal 14 passes through the sealing sleeve 13 and partially extends to the outside of the sealing sleeve 13. A shaft hole is provided on the inner wall of the winding cavity corresponding to the sealing sleeve 13, and the sealing sleeve 13 is rotatably sealed in the shaft hole. A conductive connecting piece 16 is provided on the bottom surface of the shaft hole, and the conductive connecting piece 16 is in conductive contact with the conductive contact terminal 14.

[0038] Sealing sleeves 13 are provided on both sides of the winding drum 15 and can be made of rubber. The sealing sleeves 13 can be tightly hinged with the shell of the second connector 2 to increase the sealing performance of the internal conductive contact terminal 14. The winding sleeve can realize circular rotation through the sealing sleeves 13 on both sides.

[0039] like Figure 5 As shown, a conductive buckle groove 17 is provided on the end face of the conductive contact terminal 14, and a conductive buckle point is provided on the position corresponding to the conductive buckle groove 17 on the conductive connecting piece 16. The conductive buckle point is buckled into the conductive buckle groove 17, and the conductive contact terminal 14 is conductively connected to the conductive connecting piece 16, and the conductive connecting piece 16 is conductively connected to one end of the flexible cable 12 on the side away from the conductive buckle point. The conductive connecting piece 16 is arranged inside the shell of the second connector 2 and is buckled into the conductive buckle groove 17 through the conductive buckle point to ensure that the conductive connecting piece 16 can be continuously electrically connected to the conductive contact terminal 14.

[0040] See also Figure 2 and Figure 6As shown, a hinge shaft 6 is respectively provided on both sides of the connector plate 4, and a hinge ear 5 is respectively provided on both sides of the top of the second connector 2. A torsion spring is installed on the hinge shaft 6, and the hinge shaft 6 is elastically hinged in the hinge ear 5 through the torsion spring. The torsion spring enables the connector plate 4 to be elastically pressed toward the wire coil protrusion 11 on the second connector 2. The torsion spring enables the connector plate 4 to be reset when the wire coil protrusion 11 is removed, so that the connecting pin 21 on the connector plate 4 is automatically separated from the pin connecting hole 20. Therefore, when it is necessary to separate the first connector 1 and the second connector 2, the second connecting light strip 9 is pulled at the far end to shrink the wire coil protrusion 11, thereby automatically separating the two connectors.

[0041] In order to improve the sealing performance after the connecting pin 21 is docked with the pin docking hole 20 and increase the waterproof ability of the connection position, in this embodiment, a rubber sealing layer 18 is provided on one side of the connecting pin 21 of the connector plate 4, and the connector plate 4 is lifted up by the wire coil protrusion 11, and the rubber sealing layer 18 is elastically pressed against the inclined docking surface 7. Due to its elasticity, an elastic rebound force is generated after the rubber sealing layer 18 is elastically compressed and deformed, thereby further improving the waterproof sealing performance and allowing the size value of the wire coil protrusion 11 to be a range value, thereby allowing the connecting pin 21 of the connector plate 4 to be inserted into the pin docking hole 20 with a certain pressure.

[0042] Among them, such as Figure 6 and Figure 7 As shown, a positioning buckle plate 22 is provided on the lower end surface of the connector plate 4 on one side of the connecting pin 21, and a positioning buckle groove 19 is provided on the upper end surface of the first connector 1 on one side of the pin connection hole 20. When the connecting pin 21 is inserted into the pin connection hole 20, the positioning buckle plate 22 is buckled into the positioning buckle groove 19. The connection firmness between the two connectors is further improved through the positioning buckle plate 22 and the positioning buckle groove 19. The spatial area of ​​the positioning buckle groove 19 can be larger than the positioning buckle plate 22, so that the separation of the positioning buckle plate 22 and the positioning buckle groove 19 will not be restricted by space.

[0043] Among them, such as Figure 7 As shown, in order to improve the positioning effect of the first connector 1 and the second connector 2 and increase the stability of the connectors after positioning, the second connector 2 is provided with a positioning protrusion 23 on the side relative to the first connector 1, and the first connector 1 is provided with a positioning groove 24 on the side relative to the positioning protrusion 23, and the positioning protrusion 23 and the positioning groove 24 are positioned and assembled.

[0044] The first connector 1 is provided with an inclined guide surface 10 on both sides of the inclined docking surface 7 , and the inclined guide surface 10 can reduce the accumulation of dust and rainwater.

[0045] In order to increase the contact stability between the conductive buckle point and the conductive buckle groove 17 , in this embodiment, when the conductive buckle point is buckled into the conductive buckle groove 17 , the conductive connecting piece 16 is in an elastically deformed state.

[0046] The present invention can roll up part of the connecting light strip to form a wire coil protrusion 11, and use the rolled-up connecting light strip to lift up one side of the connector plate 4, thereby allowing the connecting pin 21 to be inserted into the pin connection hole 20. Therefore, as long as the wire coil protrusion 11 is maintained, the connecting pin 21 can be stably inserted into the pin connection hole 20, effectively preventing separation. The rolled-up connecting light strip can prevent the connecting pin 21 from separating from the pin connection hole 20, simplifying the structure and making the design more reasonable.

[0047] Based on the above structure, the present invention only needs to pull the reeled connecting light strip at the far end, so that the outer diameter of the wire coil protrusion 11 becomes smaller, so that the supporting force of the wire coil protrusion 11 on one side of the connector plate 4 disappears, and the elastic hinged end of the connector plate 4 is used to reset the connector plate 4, so that the connecting pin 21 and the pin connection hole 20 are automatically separated. Therefore, the present invention only needs to operate the connecting light strip at the far end to complete the remote separation action, which is very convenient, and the light strip can be reeled, which can make the layout of the light strip more reasonable.

[0048] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
