Description

Technical Field

[0001] This invention relates to the field of lighting technology, and in particular to a cascaded splicing fixing connector for lighting fixtures. Background Technology

[0002] As is well known, the construction of long, straight track lighting fixtures requires the use of multiple sections of spliced ​​cable trays. The cable trays are installed inside the trough-shaped cable tray splicing plates, which often also need to be spliced ​​from multiple sections to achieve the required length. In the traditional method, when splicing two sections of cable tray splicing plates, screws are used to fasten the connectors at the corresponding ends of the two sections of cable tray splicing plates. This method is inefficient, requires a lot of labor intensity for operators, and often requires working at height, making the splicing process difficult.

[0003] Chinese patent (publication number: CN206449601U) discloses a novel cascaded direct-insertion connector. The patent includes a U-shaped connecting plate and a connector assembly. The inner bottom surface of the connecting plate has two vertically arranged mounting plates, which are spaced apart on the left and right. The connector assembly consists of a spring, a nut, a latch, and a screw. The latch is movably disposed between the mounting plates via the screw, and the nut is threaded to the end of the screw to achieve a limiting position. However, this patented structure can only achieve quick insertion and locking with one of the lamps, and the other end still needs to be fastened to the corresponding lamp with screws.

[0004] Chinese patent (publication number: CN209604926U) discloses a splicing LED module light. One end of the wire track box of this patent is equipped with a protruding cascaded direct-insertion locking connector assembly, and the inner side of the other end of the wire track box is equipped with a locking clip that locks with the cascaded direct-insertion locking connector assembly. Therefore, when two module light bodies are connected, the cascaded direct-insertion locking connector assembly and the locking clip lock together to realize the connection between the two. However, in actual use, it has been found that this patent structure cannot axially limit the two module light bodies. Summary of the Invention

[0005] In order to overcome the shortcomings of low operation efficiency and high splicing difficulty when using existing connectors for cascading splicing in the prior art, the present invention discloses a fixing connector for cascading splicing of lamps.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] A cascaded splicing fixing connector for lighting fixtures connects two slotted wire trough splicing plates via a slotted connecting plate. The slotted connecting plate is inserted between corresponding ends of the two wire trough splicing plates, and the free ends of the two slot walls of the wire trough splicing plates are respectively provided with bent flanges that can wrap around the free ends of the two slot walls of the slotted connecting plate; it also includes a spring clip seat and a flip positioning component.

[0008] The grooved connecting plate has an opening at one end of its bottom plate. A spring clip seat with an elastic part facing the other end of the grooved connecting plate is engaged on the outer side of the bottom plate of the grooved connecting plate corresponding to the opening. The elastic part of the spring clip seat has a spike that can engage with the bottom of one of the grooved splicing plates.

[0009] The other end of the grooved connecting plate is provided with a flip positioning component on the outer side of the groove bottom plate. The flip positioning component includes an elastic fixing seat and a rotating lever. One end of the elastic fixing seat is connected to the groove bottom plate of the grooved connecting plate. The groove bottom plate of the grooved connecting plate is provided with a rotating lever at the other end of the elastic fixing seat to make the elastic fixing seat tilt up so as to abut against the bottom of another grooved splicing plate. The rotating lever is a bent structure with a bent part that can deflect around the groove bottom plate of the grooved connecting plate to lift the elastic fixing seat.

[0010] Preferably, the end of the spring clip holder opposite to its elastic part is provided with a U-shaped part that can be engaged with the opening of the bottom plate of the grooved connecting plate, and the opening of the U-shaped part is opposite to the orientation of the elastic part of the spring clip holder. The inner side of the bottom plate of the grooved connecting plate is provided with a limiting boss corresponding to its opening, and the free end of the U-shaped part of the spring clip holder is provided with a pointed protrusion structure that can be engaged with the limiting boss.

[0011] Preferably, the groove bottom plate of the grooved connecting plate is provided with a notch at the position where it connects to the elastic fixing seat, and the elastic fixing seat is provided with a hook that is attached to the edge of the notch.

[0012] Preferably, the bottom plate of the groove-shaped connecting plate is provided with screws for locking the elastic fixing seat.

[0013] Preferably, the elastic fixing seat has a serrated structure on one side of the bottom of the groove of the corresponding wire groove splicing plate.

[0014] Preferably, the bottom plate of the grooved connecting plate has a slot at the position corresponding to the rotating lever, which allows the rotating lever body to move through, and the width of the bent part of the rotating lever is greater than the length of the slot.

[0015] Preferably, the rotating lever has a protruding post on one side of its body, and a clearance groove is provided on the corresponding side of the slot to allow the protruding post to pass through.

[0016] Preferably, the protrusions are two that are spaced apart.

[0017] Preferably, the bottom plate of the trough splicing plate is provided with limiting grooves on both sides, and the bottom plate of the trough-shaped connecting plate is provided with limiting flanges on the outside that can be matched with the limiting grooves.

[0018] Preferably, both ends of the bottom plate of the cable tray splicing plate are provided with protrusions that protrude into the inside of the cable tray splicing plate.

[0019] By employing the technical solution described above, the present invention has the following beneficial effects:

[0020] This invention discloses a cascaded splicing fixing connector for lighting fixtures, which has a simple structure and is easy to use. It achieves locking by engaging the elastic part of the spring clip with the corresponding slotted splicing plate. By rotating the lever until its body is parallel to the inner side of the slot bottom plate of the slotted connecting plate, the bent part of the lever lifts the free end of the elastic fixing seat, causing the elastic fixing seat to contact the inner side of the corresponding slot bottom plate, generating friction and thus locking the slotted splicing plate. This effectively optimizes customer installation time, reduces installation costs, and improves the efficiency of lighting fixture fixing and splicing installation on the production line.

[0030] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation.

[0031] Example 1:

[0032] Combined with appendix Figures 1-5 A cascaded splicing fixing connector for lighting fixtures, comprising a slotted connecting plate 1 connecting two slotted wire trough splicing plates 4, wherein the slotted connecting plate 1 is inserted between corresponding ends of the two wire trough splicing plates 4, and the free ends of the two slot walls of the wire trough splicing plates 4 are respectively provided with bent flanges that can wrap around the free ends of the two slot walls of the slotted connecting plate 1 to prevent the slotted connecting plate 1 from falling off; it also includes a spring clip seat 2 and a flip positioning component 3;

[0033] The grooved connecting plate 1 has an opening at one end of its bottom plate. A spring clip seat 2 with its elastic part facing the other end of the grooved connecting plate 1 is engaged with the outer side of the bottom plate of the grooved connecting plate 1 corresponding to the opening. The elastic part of the spring clip seat 2 has spikes that can engage with the bottom of one of the wire trough splicing plates 4. That is, after the grooved connecting plate 1 and the wire trough splicing plate 4 are inserted, the elastic part of the spring clip seat 2 is located between the bottom plate of the grooved connecting plate 1 and the bottom plate of the wire trough splicing plate 4. The elastic part of the spring clip seat 2 abuts against the bottom plate of the wire trough splicing plate 4 due to its own elasticity. Thus, the spikes of the elastic part of the spring clip seat 2 can abut against the inner side of the bottom plate of the wire trough splicing plate 4, thereby limiting the backward movement of the grooved connecting plate 1. The bottom plate of the grooved connecting plate 1 also has a notch that can engage with the wire trough inside the wire trough splicing plate 4 at the end with the opening.

[0034] A flip positioning component 3 is provided on the outer side of the bottom plate of the groove-shaped connecting plate 1. The flip positioning component 3 includes an elastic fixing seat 3-1 and a rotating lever 3-2. One end of the elastic fixing seat 3-1 is connected to the bottom plate of the groove-shaped connecting plate 1. The bottom plate of the groove-shaped connecting plate 1 is provided with a rotating lever 3-2 at the other end corresponding to the elastic fixing seat 3-1, which is used to tilt the elastic fixing seat 3-1 so that it abuts against the bottom of another groove splicing plate 4. The rotating lever 3-2 is a bent structure in which the bent part can deflect around the bottom plate of the groove-shaped connecting plate 1 to lift the elastic fixing seat 3-1. The bent part of the rotating lever 3-2 is located between the bottom plate of the groove-shaped connecting plate 1 and the elastic fixing seat 3-1, that is, the bent part of the rotating lever 3-2 can be made parallel to the elastic fixing seat 3-1 first, and then the other groove splicing plate 4 is inserted. After inserting the end of the slotted connecting plate 1, rotate the lever 3-2 until the body of the lever 3-2 is parallel to the inner side of the bottom plate of the slotted connecting plate 1. At this time, the bent part of the lever 3-2 pushes up the free end of the elastic fixing seat 3-1, so that the elastic fixing seat 3-1 and the inner side of the bottom of the slot of the wire trough splicing plate 4 are in contact, generating friction, thereby preventing the corresponding wire trough splicing plate 4 from moving backward. The angle between the body of the lever 3-2 and its bent part is a right angle or an obtuse angle, that is, the reaction force of the elastic fixing seat 3-1 on the bent part of the lever 3-2 can be used to achieve self-locking of the lever 3-2, avoiding accidental reverse rotation of the lever 3-2 which would cause the elastic fixing seat 3-1 to detach from the wire trough splicing plate 4. The free end of the bent part of the lever 3-2 is provided with multiple sharp teeth at intervals, which can increase the reliability of self-locking.

[0035] When using the cascaded splicing fixing connector of the present invention, the flip positioning component 3 is assembled and the bent part of the rotating lever 3-2 is parallel to the elastic fixing seat 3-1. The slotted connecting plate 1 is inserted between two wire slot splicing plates 4, and the elastic part of the spring clip seat 2 is locked with its corresponding wire slot splicing plate 4. The rotating lever 3-2 is flipped until the body of the rotating lever 3-2 is parallel to the inner side of the slot bottom plate of the slotted connecting plate 1. The bent part of the rotating lever 3-2 pushes up the free end of the elastic fixing seat 3-1, so that the elastic fixing seat 3-1 and the inner side of the slot bottom of the corresponding wire slot splicing plate 4 are in contact, generating friction, thereby achieving the purpose of locking the wire slot splicing plate 4.

[0036] Example 2:

[0037] Combined with appendix Figures 1-5A cascaded splicing fixing connector for lamps differs from Embodiment 1 in that the end of the spring clip holder 2 opposite to its elastic part is provided with a U-shaped part that can engage with the opening of the bottom plate of the groove-shaped connecting plate 1. The opening of the U-shaped part faces opposite to the elastic part of the spring clip holder 2. A limiting boss 9 is provided on the inner side of the bottom plate of the groove-shaped connecting plate 1 corresponding to its opening. The free end of the U-shaped part of the spring clip holder 2 is provided with a pointed protrusion that can engage with the limiting boss 9. That is, the spring clip holder 2 can engage with the edge of the opening of the bottom plate of the groove-shaped connecting plate 1 through its U-shaped part, and achieve self-locking through the engagement of the pointed protrusion of the U-shaped part of the spring clip holder 2 with the limiting boss 9, which can effectively prevent the spring clip holder 2 from accidentally falling off.

[0038] Example 3:

[0039] Combined with appendix Figures 1-7 A cascaded splicing fixing connector for lighting fixtures, based on embodiment one or two, wherein the bottom plate of the grooved connecting plate 1 has a notch at the connection position with the elastic fixing seat 3-1, and the elastic fixing seat 3-1 has a hook 3-4 corresponding to the edge of the notch, that is, the hook 3-4 can be hooked to the edge of the notch of the grooved connecting plate 1 to achieve positioning of the elastic fixing seat 3-1; the bottom plate of the grooved connecting plate 1 has a screw 3-3 for locking the elastic fixing seat 3-1, that is, the screw 3-3 can be used to lock the elastic fixing seat 3-1 to prevent the elastic fixing seat 3-1 from moving along the width direction of the grooved connecting plate 1;

[0040] There are two ways to install screw 3-3. One way is to move screw 3-3 through the bottom plate of the grooved connecting plate 1 from the inside and then thread it onto the elastic fixing seat 3-1. The other way is to move screw 3-3 through the elastic fixing seat 3-1 and then thread it onto the bottom plate of the grooved connecting plate 1. Both methods can achieve a firm fixation of the elastic fixing seat 3-1. At the same time, two screws 3-3 can be spaced apart to further improve the reliability of the connection.

[0041] The groove bottom plate of the groove-shaped connecting plate 1 is provided with a slot 5 at the position corresponding to the rotating lever 3-2, which allows the rotating lever 3-2 to move through. That is, when assembling the flip positioning component 3, the rotating lever 3-2 can be made to pass through the slot 5 first, so that the rotating lever 3-2 can be flipped. The structure is simple and easy to assemble. Moreover, the width of the bent part of the rotating lever 3-2 is greater than the length of the slot 5, which can prevent the rotating lever 3-2 from coming out of the slot 5.

[0042] The rotating lever 3-2 has a protruding post 3-5 on one side of its body, and the corresponding side of the slot 5 has a relief groove that allows the protruding post 3-5 to pass through. This means that the cooperation between the protruding post 3-5 and the relief groove can achieve the effect of preventing fooling and avoiding the rotating lever 3-2 from being inserted backwards. The protruding posts 3-5 are arranged in two spaced intervals. In addition to the purpose of preventing fooling, the cooperation between the protruding posts 3-5 and the relief groove can also achieve the effect of guiding, ensuring that the rotating lever 3-2 can be smoothly inserted into the slot 5. When the flip positioning component 3 is locked, the protruding post 3-5 is away from the bottom plate of the slotted connecting plate 1, ensuring that the rotating lever 3-2 can fit against the inner side of the bottom plate of the slotted connecting plate 1.

[0043] In addition, the elastic fixing seat 3-1 is provided with a serrated structure on one side of the bottom of the groove of the wire groove splicing plate 4, which can effectively increase the friction between the elastic fixing seat 3-1 and the bottom of the groove of the wire groove splicing plate 4, further preventing the corresponding wire groove splicing plate 4 from moving backward, and the serrated structure can be arranged in two or more rows at intervals.

[0044] Example 4:

[0045] Combined with appendix Figures 1-8 A cascaded splicing fixing connector for lighting fixtures, based on any one of the embodiments in embodiments one to three, wherein the bottom plate of the cable tray splicing plate 4 is provided with limiting grooves 6 on both sides, and the bottom plate of the channel-shaped connecting plate 1 is provided with limiting flanges 7 on the outer side that can be matched with the limiting grooves 6, that is, the axial positioning of the cable tray splicing plate 4 can be achieved by the cooperation of the limiting grooves 6 and the limiting flanges 7.

[0046] Example 5:

[0047] Combined with appendix Figures 1-8 A cascaded splicing fixing connector for lighting fixtures, based on any one of the embodiments in Examples 1 to 4, wherein both ends of the bottom plate of the cable tray splicing plate 4 are provided with protrusions 8 that protrude towards the inside of the cable tray splicing plate 4, that is, the elastic part of the spring clip seat 2 and the elastic fixing seat 3-1 can both contact the corresponding protrusions 8, further improving the firmness of the connection.

[0048] The parts of this invention not described in detail are prior art. It will be apparent to those skilled in the art that this invention is not limited to the details of the above exemplary embodiments, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
