Description

Technical Field

[0001] The utility model relates to the field of lighting, and more specifically, to a wire fixing structure and a lamp. Background Art

[0002] As an important part of the lamp to connect to the external power supply, the power cord usually needs to pass through the housing to connect to the light source module, drive power module and other electrical components inside the lamp. During the use of the lamp, the position or angle usually needs to be adjusted frequently, which will make the power cord susceptible to external force pulling. In order to prevent the power cord from loosening or even breaking due to pulling during use, it is extremely important to fix the power cord to the lamp reliably. Usually, a clamping structure is used to fix the power cord to limit the relative displacement between the power cord and the lamp.

[0003] The commonly used wire clamping structure at present is usually to inject a wire clamping block on the power cord, and then fix the wire clamping block on the housing, so as to achieve the purpose of fixing the power cord on the lamp body. However, the injection molding of the power cord is not only complicated, but also the wire clamping block is not convenient to be installed corresponding to the housing. Therefore, a new wire fixing structure is urgently needed to solve the above technical problems. Utility Model Content
