Description

Technical Field

[0001] The invention relates to the technical field of energy-saving lamps, and in particular to a soldering-free lamp holder structure which is convenient for replacing light sources. Background Art

[0002] Most of the existing lamps are energy-saving lamps or LED lamps. Regardless of whether they are energy-saving lamps or LED lamps, they generally include a lamp head, a light source and a lampshade. The lamp head is used to connect to the lamp holder to connect the power signal of the lamp holder to the light source of the lamp, and the lampshade covers the lamp head to protect the light source.

[0003] For example, a Chinese patent with publication number CN117570403A discloses a lamp holder structure with a replaceable light source, including at least one lamp holder assembly, and a bulb assembly is arranged inside the lamp holder assembly. The lamp holder assembly includes a lamp holder shell and a lamp holder plastic shell arranged inside the lamp holder shell, and a low-voltage quick-connect terminal plastic shell is arranged inside the lamp holder plastic shell. At least two high-voltage wire cores and at least two low-voltage wire cores are passed through the interior of the lamp holder shell, and one end of the low-voltage wire core is fixedly arranged inside the low-voltage quick-connect terminal plastic shell. When the light source needs to be replaced, it is necessary to unscrew the bulb assembly, and then pull out the light guide column and the lamp board, so that the conductive terminal is separated from the low-voltage quick-connect terminal plastic shell. However, after long-term use, the conductive terminal and the lamp board are prone to aging. When the lamp board is pulled out with force, the conductive terminal is easy to separate from the lamp board, resulting in the conductive terminal still being inserted in the low-voltage quick-connect terminal plastic shell, and the light source cannot be replaced.

[0043] When the light source needs to be replaced, the insulating cover 13 is pushed toward the fixing seat 23 to force the telescopic column 15 to disengage from the groove 133, so that the telescopic column 15 slides in the direction away from the support portion 211, thereby reducing the force of the telescopic column 15 squeezing the support portion 211 and facilitating the removal of the support portion 211; then, the first limiting portion 255 is pressed downward to force the base plate portion 254 to deform until the second limiting portion 256 is separated from the cover portion 231, and then the fixing seat 23 is removed, so that the lamp holder 21, the lamp board 22 and the conductive terminal 24 are removed together, and then the fastening plate 26 is rotated to take out the lamp board 22, which is convenient for replacement and easy to use; moreover, the conductive terminal 24 will not be separated from the lamp board 22.

[0044] The solder-free lamp holder structure 100 of the present invention, which is convenient for replacing light sources, can be detachably mounted on the lamp holder 21 through the lamp board 22.
