Abstract

The invention relates to a lamp and a circuit board fixed-connection structure thereof. The circuit board fixed-connection structure comprises a circuit board, four ejecting pins, an installing shell, a fixed column, a first ejecting-pin pressing piece and a second ejecting-pin pressing piece, wherein each ejecting pin comprises a connecting section, a contact with elastic resetting and a positioning flange positioned between the connecting section and the contact; the installing shell is in a barrel shape with one opened end and one closed end; the first end of the fixed column is connected with the opened end of the installing shell; the first ejecting-pin pressing piece is connected with the closed end of the installing shell; the second ejecting-pin pressing piece is connected with the second end of the fixed column; the circuit board is fixed in the installing shell; two ejecting pins are positioned between the installing shell and the first ejecting-pin pressing piece, the connecting sections are respectively and electrically connected with the circuit board, and the contacts are exposed from the first ejecting-pin pressing piece; and the other two ejecting pins are positioned between the fixed column and the second ejecting-pin pressing piece, the connecting sections are respectively and electrically connected with the circuit board, and the contacts are exposed from the second ejecting-pin pressing piece. Therefore, the lamp and a circuit board fixed-connection structure thereof disclosed by the invention have the advantage that the time and the cost for replacing a light-source component are saved.

Description

technical field [0001] The invention relates to components of a lamp, more specifically, to a lamp and a fixed connection structure for a circuit board thereof. Background technique [0002] In the current LED lamps, after the PCB (printed circuit board, printed circuit board) is fixed, it is generally connected to the light source through wires, and at the same time connected to the conductive sheet and thimble through the wire, so as to further connect to the power supply through the conductive sheet and thimble. The disadvantages are Inconvenient to replace the light source. For some lamps, such as portable command sign lamps, the light source is easily damaged due to its special purpose, and the color of the light source needs to be changed frequently to achieve different command languages; if wires are used to connect the PCB and the light source, when replacing the light source, it is necessary to Remove the wire first, and then re-solder the new wire after replacing ...
