Description

Technical Field

[0001] The utility model relates to the technical field of LED lamp beads, and particularly relates to a plug-in LED lamp bead. Background Technique

[0002] The encapsulation of LED lamp beads refers to the encapsulation of LED light-emitting chips and control chips. For LED lamp beads, only the light-emitting chips are encapsulated, and the control chips are not integrated in the encapsulation. During the use of the lamp beads, the encapsulated lamp beads and the control chips are assembled in the application circuit, and the LED lamp beads are controlled by an external control chip.

[0003] Since LED lamp beads are often fixed by welding, when one of the LED lamp beads is damaged, it is necessary to remove the old lamp bead by heating and then weld a new lamp bead. During the welding process, the lamp bead is often damaged and cannot be used. Therefore, we propose a plug-in LED lamp bead that is easy to disassemble and assemble. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a plug-in LED lamp bead, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A plug-in LED lamp bead, including a bottom plate. On the upper surface of the bottom plate, a positive electrode mounting seat and a negative electrode mounting seat are fixedly connected in sequence from left to right. A circular hole is opened inside the positive electrode mounting seat, and a square hole is opened inside the negative electrode mounting seat. A positive electrode connecting column is inserted into the circular hole, and a negative electrode connecting column is inserted into the square hole. The tops of the positive electrode connecting column and the negative electrode connecting column are both electrically connected to the lamp bead.

[0007] To prevent the lamp bead from loosening easily after installation, as a plug-in LED lamp bead of the utility model, a positioning plate is fixedly connected to the middle of the lower surface of the lamp bead, and a jack is opened on the front surface of the positioning plate.

[0008] To make the position of the limiting ring more stable, as a plug-in LED lamp bead of the utility model, a support rod is fixedly connected to the upper surface of the bottom plate, and one end of the support rod far from the bottom plate is fixedly connected to the limiting ring.

[0009] To make the baffle reset after the external force is removed, as a plug-in LED lamp bead of the utility model, a compression spring is fixedly connected to the front surface of the limiting ring, and one end of the compression spring far from the limiting ring is fixedly connected to the baffle.

[0010] In order to make the installation of the lamp beads more stable, as a plug-in LED lamp bead of the present utility model, a plug post is fixedly connected to the middle of the back surface of the baffle, and the plug post is inserted into the inside of the limiting ring.

[0011] In order to facilitate the movement control of the plug post, as a plug-in LED lamp bead of the present utility model, a handle ring is fixedly connected to the front surface of the baffle, and the handle ring is made of plastic.

[0012] In order to make the fixing of the mounting piece more firm, as a plug-in LED lamp bead of the present utility model, mounting pieces are fixedly connected to both the front and back surfaces of the bottom plate, and a locking bolt is arranged inside the mounting piece.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

For this plug-in LED lamp bead, through the cooperation setting among the bottom plate, the positive electrode mounting seat, the negative electrode mounting seat, the circular hole, the square hole, the positive electrode connection post, the negative electrode connection post and the lamp bead, an insertion-type combined structure is adopted, which can make the replacement of the lamp bead more convenient. And the positive electrode connection post and the negative electrode connection post adopt different-shaped terminals, which can effectively avoid the situation of wrong connection of the positive and negative electrodes, and the safety is higher.

[0015] 2. For this plug-in LED lamp bead, through the cooperation setting among the positioning plate, the jack, the support rod, the limiting ring, the compression spring, the baffle, the plug post and the handle ring, after the lamp bead is installed, when the pulling force on the handle ring is removed, the plug post can move under the action of the compression spring and be inserted into the inside of the positioning plate and the limiting ring, then the positioning plate can be limited, making the installation of the lamp bead more firm and not easy to loosen.

Moreover, since the positive electrode terminal 6 and the negative electrode terminal 7 adopt terminals with different shapes, the situation of incorrect connection of the positive and negative electrodes can be effectively avoided, and the safety is higher.

[0026] In this embodiment, a positioning plate 9 is fixedly connected to the middle of the lower surface of the lamp bead 8, and a jack 10 is opened on the front surface of the positioning plate 9.

[0027] During specific use, through the setting of the positioning plate 9 and the jack 10, the plug post 15 is inserted into the jack 10, which is convenient for limiting the positioning plate 9.

[0028] In this embodiment, a support rod 11 is fixedly connected to the upper surface of the bottom plate 1, and one end of the support rod 11 away from the bottom plate 1 is fixedly connected to the limiting ring 12.

[0029] During specific use, through the setting of the support rod 11, the position of the limiting ring 12 can be fixed more firmly, and the stability is better.

[0030] In this embodiment, a compression spring 13 is fixedly connected to the front surface of the limit ring 12, and a baffle 14 is fixedly connected to the end of the compression spring 13 away from the limit ring 12.

[0031] During specific use, due to the arrangement of the compression spring 13, the baffle 14 can move towards the limit ring 12 when no external force pulls it.

[0032] In this embodiment, a plug post 15 is fixedly connected to the middle of the back surface of the baffle 14, and the plug post 15 is inserted into the interior of the limit ring 12.

[0033] During specific use, through the cooperative arrangement among the positioning plate 9, the jack 10, the support rod 11, the limit ring 12, the compression spring 13, the baffle 14, the plug post 15, and the handle ring 16, after the lamp bead 8 is installed, when the pulling force on the handle ring 16 is removed, the plug post 15 can move under the action of the compression spring 13 and be inserted into the positioning plate 9 and the interior of the limit ring 12, thereby limiting the positioning plate 9 and making the installation of the lamp bead 8 more firm and not prone to loosening.

[0034] In this embodiment, a handle ring 16 is fixedly connected to the front surface of the baffle 14, and the handle ring 16 is made of plastic.

[0035] During specific use, due to the arrangement of the handle ring 16, it is convenient to control the movement of the plug post 15.

[0038] Working principle: When installing the lamp bead 8, the staff can first pull the handle ring 16 by hand. Under the pulling force, the plug post 15 can be moved out of the limit ring 12. Then, the staff can insert the positive terminal 6 into the positive mounting seat 2 and the negative terminal 7 into the negative mounting seat 3. At this time, the positioning plate 9 is inserted into the limit ring 12. The staff releases the handle ring 16, and the plug post 15 is inserted into the jack 10 to limit the positioning plate 9, thus completing the installation of the lamp bead 8.
