Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a connection structure between a lamp housing and a power cord. Background Technique

[0002] LED lamps are becoming the main products in the new generation of lighting market with their technical characteristics such as high efficiency, energy saving, safety, long life, small size, and clear light, and strongly driving the high-speed development of the environmental protection and energy-saving industry.

[0003] There are mainly two types of electrical connections for LED lamps: 1. Direct wire output (the power cord is welded on the PCB pad or the power cord is riveted to the terminal and inserted into the PCB plug-in); 2. Embedded terminal wire output (the terminal pin is welded to the PCB pad through a lead or a copper pin). The above two connection methods both have low assembly efficiency, affecting the improvement of production efficiency and large-scale mass production. Therefore, further improvement is needed.

[0004] Therefore, based on the above technical problems, it is necessary for those skilled in the art to develop a connection structure between a lamp housing and a power cord. Content of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A connection structure between a lamp housing and a power cord includes a lamp housing and a power cord. A PCB board is arranged inside the lamp housing, a transfer board is arranged on the PCB board, a through hole is opened on the lamp housing, a connecting piece is installed on the power cord, and the connecting piece is arranged inside the through hole.

[0008] As a preferred technical solution, the connecting piece is a tail card.

[0009] As a preferred technical solution, the tail card is fixed at one end of the power cord through an injection molding integral process.

[0010] As a preferred technical solution, the tail card includes a first limiting block, a second limiting block is integrally formed and installed on one side of the first limiting block, a third limiting block is integrally installed on the side of the second limiting block away from the first limiting block, and a clamping groove is formed between the first limiting block and the third limiting block.

[0011] As a preferred technical solution, an arc is arranged on the side of the first limiting block away from the second limiting block.

[0012] As a preferred technical solution, a limiting sleeve is integrally formed and installed on one side of the lamp housing.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: in this utility model, the user inserts the tail sleeve into the through hole. At this time, the limiting sleeve just engages in the engaging groove, which facilitates the staff to quickly assemble the power cord on the rear shell with high assembly efficiency. Moreover, automation can be achieved, improving the production efficiency of the entire factory and enabling large-scale production. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The features and exemplary embodiments of various aspects of the present utility model will be described in detail below. In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. For those skilled in the art, the present utility model can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present utility model by showing examples of the present utility model.

[0019] As Figures 1-3 shown, the present utility model provides a technical solution for a connection structure between a lamp rear shell and a power cord: including a rear shell 1 and a power cord 2. Among them, a PCB board 10 is installed in the rear shell 1, an adapter board 3 is provided on the PCB board 10. At the same time, a through hole is opened on the rear shell 1, the through hole is horizontally opened, and a connecting member is provided in the through hole.

[0020] In this embodiment, the connecting member is a tail card 4. Among them, the tail shell includes a first limiting block 5, a second limiting block 6 is integrally formed and installed on one side of the first limiting block 5, a third limiting block 7 is integrally installed on the side of the second limiting block 6 away from the first limiting block 5, and an engaging groove 8 is formed between the first limiting block 5 and the third limiting block 7.
