Strip-shaped lamp

Technical Field

The invention relates to a strip lamp, in particular to a strip lamp which can be connected with each other through plugging.

Background

Various lighting fixtures have been developed in every aspect of daily life as a necessity for home and commercial lighting. In lighting or decoration environments such as showcases, homes and the like, lamps for lighting or decoration are often required to be exquisite in appearance and simple in structure, and the length of the lamps can be conveniently adjusted according to installation requirements.

In the prior art, the lamp is generally pressed and connected by a metal spring sheet arranged on the plug and a conducting sheet arranged in the socket to form an electrical connection. The plug of the lamp supports the metal elastic sheet through an insulating plug body. The socket of the lamp is substantially surrounded by a cavity arranged at one end of the lamp holder, so that a special limiting mechanism which is in plug-in fit with the plug is lacked. Due to the existence of the metal elastic sheet, the cavity reserves a space for accommodating the metal elastic sheet, so that the cavity still has a gap after the insulating plug-in body is inserted, the insulator still has a movable space in the cavity, and the connection performance of the plug and the socket is poor. In addition, after the plug and the socket of the lamp are plugged, all external forces of the lamp in the radial direction of the lamp holder are borne by the insulating plug body, so that the insulating plug body is easily damaged. Thus, the mechanical connection strength of the plug and the socket of the lamp in the radial direction of the lamp holder is low. Especially, under the condition that the lamp is bent or the weight of the lamp is large, the problem that the plug, the socket or the circuit board is easily slipped or even broken occurs, namely, the plug and the socket can not realize the technical effect of mutual limiting in the radial direction of the lamp holder, and further good electrical connection can not be realized. In addition, on the premise that lamps using LEDs (Light Emitting diodes) as Light sources are increasingly widely used, the service life of the Light sources is greatly prolonged, and the service experience and service life of the lamps are greatly affected by the weakening or losing of the connection function between the plug and the socket.
