Technical Field

[0001] The utility model belongs to the technical field of lamps and relates to an LED lamp holder. Background Art

[0002] Holiday lights are decorative lamps that generally use LED bulbs of different colors to create a colorful light strip effect to set off the festive atmosphere. Holiday lights generally include a lamp holder, an LED wick and a lampshade. The lamp holder has a mounting cavity, a PCB circuit board is arranged in the mounting cavity, the PCB circuit board is connected to the LED wick, a wiring hole is opened on the side wall of the upper end of the lamp holder, a power cord is connected to the PCB circuit board, the power cord passes through the wiring hole so that the outer end of the power cord extends out of the lamp holder, so that the PCB circuit board can be connected to an external power source through the outer end of the power cord.

[0003] At present, the existing lamp holders are generally one-step injection molded. For example, the China Patent Network discloses a lamp holder for a hanging lamp [Authorization Announcement No.: CN204387993U], which includes an assembly, a wiring body is provided on the upper side of the assembly, and support bodies are integrally formed on opposite sides of the wiring body. The cables pass through the support bodies and extend into the wiring body respectively. The assembly and the wiring body are integrally formed, and a protruding convex ring is integrally formed on the outer surface of the lower side of the assembly. The lower side of the assembly is provided with an installation opening for installing a light bulb.

[0004] The assembly, the wiring body and the support body in the lamp holder are formed by injection molding. When the PCB circuit board is installed, the power cord is first set in the wiring body and one end of the power cord is passed through the support body, and then the PCB circuit board is set in the assembly body, and then one end of the power cord is welded to the PCB circuit board, and finally the PCB circuit board is fixed to the assembly. Due to the small internal space of the wiring body, the operating space when the power cord is installed is limited, and the support body and the wiring body are arranged vertically, so that it is necessary to bend 90 degrees in the process of passing through the support body and the wiring body. These factors increase the difficulty of installing the power cord, so that the installation of the power cord takes a lot of time, which seriously affects the assembly efficiency of the lamp. After the power cord is installed, one end of the power cord needs to be welded to the PCB circuit board, and finally the PCB circuit board is fixed to the assembly, so that the installation steps of the power cord and the PCB circuit board on the lamp holder are numerous, which further affects the assembly efficiency of the lamp. Summary of the invention

[0012] In the above-mentioned LED lamp holder, the positioning sleeve and the positioning column are respectively arranged in the corresponding assembly part. Through the arrangement of this structure, since the assembly part is larger in volume than the wiring part and the support part, the positioning sleeve and the positioning column are arranged in the assembly part to improve the connection stability between the two assembly parts.

[0013] In the above-mentioned LED lamp holder, the inner wall of the assembly part has a second boss, the second boss is located below the first boss, the limiting protrusion is arranged on the side wall of the second boss, and an internal thread is provided on the inner wall of the assembly part below the second boss. Through the arrangement of this structure, an internal thread is provided on the inner wall of the assembly part below the second boss, so that the lampshade can be screwed onto the lamp holder conveniently, and the upper end of the lampshade abuts against the lower surface of the second boss.

[0014] Compared with the prior art, the lamp holder of the utility model has the following advantages: the lamp holder of the present structure is a split structure. When not welded, the inner cavities of the two half-holders are both open. At this time, it is very convenient to arrange the PCB board and the power cord on one of the half-holders. After the PCB board and the power cord are arranged on one of the half-holders, the other half-holder can be buckled on, thus completing the arrangement of the PCB board and the power cord in the lamp holder. The two half-holders are then ultrasonically welded to form the lamp holder, thereby shortening the time required for installing the PCB board and the power cord, and significantly improving the installation efficiency of the PCB board and the power cord on the lamp holder.
