DETAILED DESCRIPTION

[0026] The following is combined with Figures 1 to 8 The utility model is described in detail.

[0027] The utility model discloses a light board plug-in type LED light bulb, comprising a lamp holder 1 and a bulb shell 2 fixedly connected to the lamp holder 1, and also comprising an insulating fixing seat 3 and a light board type light source assembly 4 for vertical installation; the insulating fixing seat 3 is arranged at the mouth of the bulb shell 2, and the insulating fixing seat 3 at least comprises an assembly portion 31 tightly assembled with the mouth of the bulb shell 2 and a plug-in portion 32 for installing the light board type light source assembly 4, the plug-in portion 32 is provided with a plug-in slot 321, and the inner side of the plug-in slot 321 has at least two conductive contacts a322, wherein one conductive contact a322 is electrically connected to the positive pole of the lamp holder 1, and the other conductive contact a322 is electrically connected to the positive pole of the lamp holder 1, and the other conductive contact a322 is electrically connected to the positive pole of the lamp holder 1. A conductive contact a322 is electrically connected to the negative pole of the lamp holder 1; the lamp panel type light source assembly 4 includes at least a substrate 41 and electrically connected LEDs 42 arranged along at least two opposite surfaces of the substrate 41, the substrate 41 is provided with a circuit, the LED 42 is electrically connected to the circuit, and a fluorescent glue layer 43 is coated on the outer surface of the LED 42; the substrate 41 is provided with two conductive contacts b411, one end of the substrate 41 is inserted into the plug-in slot 321 and makes the conductive contact b411 and the conductive contact a322 conduct to each other, and the other end of the substrate 41 extends into the bulb 2.

[0028] The utility model improves the wick structure of the existing light bulb, and improves the existing welded wick structure into a lamp board plug-in wick structure. The insulating fixing seat 3 and the lamp board are electrically connected through the conductive contact a322 and the conductive contact b411. It is no longer necessary to use a welding process to make the two ends of the light bar electrically connected to the metal wire, thereby significantly simplifying the molding process of the light bulb, shortening the overall molding time of the light bulb, and greatly reducing the molding cost of the light bulb; secondly, after the light board is integrated, it is directly inserted into the plug-in slot 321 to complete the entire assembly process of the wick, and the assembly efficiency of the wick is also greatly improved.

[0029] In the present technical solution, one of the conductive contacts a322 is electrically connected to the positive pole of the lamp holder 1 through the first conductive wire 5, and the other conductive contact a322 is electrically connected to the negative pole of the lamp holder 1 through the second conductive wire 6. The insulating fixing seat 3 is provided with at least two wire holes 33; one end of the first conductive wire 5 and the second conductive wire 6 respectively pass through the wire holes 33 and extend at least to the plug-in slot 321.

[0030] Based on the above solution, as an embodiment, Figure 3 As shown, the first conductive wire 5 and the second conductive wire 6 both extend out of the insertion slot 321 and form a bent portion 51, and the bent portion 51 reversely hooks the side wall of the insertion slot 321 to form a positioning installation of the conductive wire. At this time, the conductive contact a322 is a part of the first conductive wire 5 and the second conductive wire 6. The arc-shaped bend formed after the conductive wire is bent also makes the conductive contact a322 elastic, so that the conductive contact a322 and the conductive contact b411 can always maintain a close fit and have good conductive contact.

[0031] In order to further hide the conductive wire and better fix the conductive wire, the side wall of the plug-in slot 321 is provided with a receiving slot 327 for accommodating the bent portion 51 . The receiving slot 327 is also conducive to making the structure more compact and preventing the end of the conductive wire from protruding.

[0032] As another embodiment, Figure 4 As shown, the conductive contact a322 is a conductive spring 323 embedded in the insertion slot 321, and the first conductive wire 5 and the second conductive wire 6 are respectively electrically connected to the conductive spring 323. The conductive spring 323 is elastic and can also make the conductive contact a322 and the conductive contact b411 form a good electrical contact.

[0033] Preferably, a partition plate 324 is further provided inside the plug slot 321, and the partition plate separates the two conductive contacts a322 and the first conductive wire 5 and the second conductive wire 6 to prevent the two electrodes from accidentally touching each other and causing a short circuit of the bulb. Similarly, the substrate 41 is provided with a socket 412 that cooperates with the partition plate 324, and the two conductive contacts b411 are respectively located on both sides of the notch, which can also prevent the bulb from short circuiting. Secondly, the lamp board is plugged into the partition plate 324, which can form a fixed support for the substrate 41 and realize a stable installation of the lamp board.

[0034] Preferably, the assembly part 31 is formed of a soft rubber material, so that the assembly part 31 can be tightly assembled with the mouth of the bulb shell 2, and the mouth of the bulb shell 2 is sealed, so that the bulb has good waterproof performance; the plug-in part 32 is formed of a hard colloid material, and the plug-in part 32 formed of a hard material can ensure that the conductive contact does not shift, and ensure the stable contact between the conductive contact a322 and the conductive contact b411. The insulating fixing seat 3 formed of two materials can make the bulb have good waterproof performance and good electrical contact.

[0035] As an example, Figure 5 As shown, the plug slot 321 has a blocking bottom plate 10, and the wire hole 33 is set on the blocking bottom plate 10. When the substrate 41 is installed in the plug slot 321, the blocking bottom plate 10 can limit it to avoid over-insertion. The top of the assembly part 31 is provided with an assembly slot 311 for the plug part 32 to be plugged and assembled. At this time, the assembly part 31 covers the plug part 32.

[0036] As another embodiment, Figure 6As shown, the top of the assembly portion 31 is provided with a protrusion 312 extending upward; the bottom of the plug portion 32 is provided with a mounting groove 325 for accommodating the protrusion 312. At this time, the plug portion 32 covers the assembly portion 31. In this embodiment, the plug slot 321 also has a blocking bottom plate 10, and the wire hole 33 is provided on the blocking bottom plate 10. When the substrate 41 is installed in the plug slot 321, the blocking bottom plate 10 can limit it to avoid over-insertion.

[0037] Preferably, the protruding portion 312 is provided with at least two positioning holes 313, and the mounting groove 325 is provided with at least two positioning posts 326, and the positioning posts 326 are inserted into the positioning holes 313, and the assembly portion 31 and the plug-in portion 32 are positioned and installed through the positioning posts 326 and the positioning holes 313. Adding this structure can help improve the production and assembly efficiency of the insulating fixing seat 3.

[0038] In the present technical solution, the assembly portion 31 and the plug-in portion 32 can be formed separately and then assembled into one body, or can be integrally formed by injection molding in two steps.

[0039] In the present technical solution, the substrate 41 is formed of PVC material. Compared with the ceramic substrate 41, the PVC substrate 41 has better toughness, is not easy to bend and break, and has a longer service life; the substrate 41 is a T-shaped thin plate, including an insertion portion 413 and a light source portion 414, wherein the width of the insertion portion 413 is greater than that of the light source portion 414, so that the substrate 41 can form a stable support for the light source portion 414 after being plugged in; the conductive contact b411 is in the shape of a long strip and is arranged on the surface of the insertion portion 413. The long strip and block-shaped conductive contact b411 has a larger contact area, and the conductive contact a322 and the conductive contact b411 can be better conductive.

[0040] The utility model further comprises at least one resistor 7, which is arranged on the conductive line or integrated on the substrate 41. When integrated on the substrate 41, it has better cost advantage and assembly efficiency advantage.

[0041] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
