DETAILED DESCRIPTION

[0018] The technical solution described in this application is further described below in conjunction with the accompanying drawings and embodiments.

[0019] Example 1

[0020] like Figures 1 to 6A ceramic lamp holder comprises a lamp holder body 2, lamp holder hooks 3 for engaging with a lamp ring are arranged on both sides of the lamp holder body 2, a lamp bead insertion hole 10 extending downward is processed on the top end surface of the lamp holder body 2, a spring support plate 15 is arranged at the bottom end of the lamp bead insertion hole 10, and the spring support plate 15 is integrated with the lamp holder body 2.

[0021] Lamp holder connecting holes 4 are processed at the lamp holder body 2 on both sides of the lamp bead plug-in hole 10. The lamp holder connecting holes 4 are stepped through holes and penetrate the lamp holder body 2. Lamp holder clamping grooves 6 are processed on the side of the lamp bead plug-in hole 10 where the lamp holder connecting holes 4 are not provided. The lamp holder clamping grooves 6 extend downward along the lamp bead plug-in hole 10, and an inclined surface is formed on the bottom surface of the lamp holder clamping grooves 6.

[0022] A limiting spring bent end 8 is placed inside the lamp holder slot 6, and the limiting spring bent end 8 and the limiting spring 9 form a whole. The limiting spring bent end 8 is formed by bending the limiting spring 9 toward the direction of the lamp bead 1, and the limiting spring bent end 8 is engaged with the plug-in end protrusion 7. The plug-in end protrusion 7 is distributed on the side of the lamp bead plug-in end 13, and the lamp bead plug-in end 13 and the lamp bead 1 form a whole.

[0023] The limiting spring piece 9 is a U-shaped elastic metal sheet. The bottom surface of the limiting spring piece 9 is in contact with the spring piece supporting plate 15 and is supported by the spring piece supporting plate 15 , and the outer side surface of the limiting spring piece 9 is in contact with the inner wall of the lamp bead plug-in hole 10 .

[0024] The limiting spring piece 9 is stamped to form a limiting claw 12 at a position close to the bottom surface, and the limiting claw 12 is folded toward the outside of the limiting spring piece 9. A groove is processed at the lamp holder body 2 corresponding to the limiting claw 12. After the limiting spring piece 9 is plugged into place, the limiting claw 12 can be engaged with the groove at this position, thereby ensuring the connection stability of the limiting spring piece 9 and the lamp holder body 2 after being plugged into place.

[0025] The lamp holder body 2 is processed with a spring plug-in hole 14 on the inner side of the lamp holder connection hole 4, and a joint electric spring 5 is inserted into the spring plug-in hole 14. The joint electric spring 5 extends into the lamp holder body 2 and extends to the position of the pin stop block 16. The pin stop block 16 is integrally arranged inside the lamp bead plug-in hole 10, and a groove for accommodating the joint electric pin of the lamp bead 1 is arranged at the middle position of the pin stop block 16. The joint electric spring 5 is bent outward at the top end extending into the lamp holder body 2 to form a joint electric connection end 11. The joint electric spring 5 is bent at the bottom and processed with a through hole corresponding to the lamp holder connection hole 4. The joint electric spring 5 can be connected to the lamp holder connection hole 4 by screws or rivets.

[0026] Based on the above embodiments, the following paragraphs will continue to describe in detail the technical features involved and the functions and roles played by the technical features in the present technical solution, so as to help technicians in this field to fully understand the technical solution and reproduce it.

[0027] See also Figures 1 to 6 In the present application, the lamp holder body 2 is connected to the external stainless steel ring body through the lamp holder hooks 3 on both sides to achieve a detachable snap connection.

[0028] In the present application, the lamp bead 1 has a lamp bead plug-in end 13 which can be used for connection, limiting and connecting electricity after insertion. The lamp bead plug-in end 13 should be evenly distributed with a number of plug-in end protrusions 7 on the side facing the lamp holder slot 6 so that the plug-in end protrusions 7 can be engaged and limited with the bent end 8 of the limiting spring in the lamp holder slot 6.

[0029] The limiting spring piece 9 is formed by bending an elastic metal plate into a U-shape, and limiting claws 12 that are folded outward are stamped on both sides of the bottom end of the limiting spring piece 9. The top end of the limiting spring piece 9 is bent toward the direction of the plug-in end protrusion 7 to form a limiting spring piece bent end 8. The limiting spring piece bent end 8 is located in the lamp holder slot 6. The bottom end of the lamp holder slot 6 is an inclined surface, and the inclined surface is in contact with the bending position of a part of the limiting spring piece bent end 8.

[0030] The bending end 8 of the limiting spring piece is an acute-angle or obtuse-angle bending structure.

[0031] The lamp holder body 2 is integrally provided with a spring support plate 15 at the bottom end of the lamp bead plug-in hole 10, and gaps are left on both sides of the spring support plate 15 to penetrate the lamp bead plug-in hole 10, and the gaps are convenient for observing whether the limiting spring 9 is plugged in place. After the limiting spring 9 is pressed down from the top of the lamp bead plug-in hole 10, the bottom end of the limiting spring 9 contacts the spring support plate 15, and the limiting claws 12 at the bottom end of the limiting spring 9 can be engaged with the grooves on both sides of the spring support plate 15, so as to realize the fixing of the limiting spring 9 in the lamp bead plug-in hole 10.

[0032] The lamp holder body 2 is processed with lamp holder connection holes 4 on both sides of the lamp bead plug hole 10, where the lamp holder slot 6 is not provided. The lamp holder connection hole 4 penetrates the lamp holder body 2. A UDM spring 5 is connected to the bottom end of the lamp holder connection hole 4. The through hole of the UDM spring 5 is aligned with the lamp holder connection hole 4, and the UDM spring 5 also extends through the spring plug hole 14 on the side of the lamp holder connection hole 4 to the position of the pin limit block 16. The pin limit block 16 is arranged on both sides of the lamp holder slot 6 and is fixed to the lamp holder body 2 as a whole. The top of the UDM spring 5 is bent to form a spring plug hole 14, and the spring plug hole 14 can cooperate with the step structure at this position to realize its own top limit.

[0033] The UMC spring 5 is electrically connected to the UMC pin via the UMC connecting end 11 . The UMC pin is located at the lamp bead plug-in end 13 and is accommodated in the groove of the pin limiting block 16 .

[0034] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
