Showcase

Abstract

The present invention provides a showcase, capable of connecting electrically a terminal of an illuminating lamp and a power supply part arranged on a socket reliably and safely, and simplifying the mounting operation of the illuminating lamp. The showcase (1) of the invention is provided with a socket (22) composed of a mainbody side socket component (23) and an illuminating lamp side socket component (24) mounted on the illuminating lamp (14), under a condition that a fixture claw (40) of the socket component (23) and a fixture claw (41) of the socket component (24) are dismounted freely, aterminal (14A) of the illuminating lamp is connected with a power supply contact piece (35) of the socket component (23) electrically, furthermore, a prominence (29B) of the socket component (23) projects from a penetrating hole (62) of the socket component (24) when the fixture claw (40) is fixed in the fixture claw (41).

Description

technical field [0001] The invention relates to a display cabinet, which is provided with a lighting lamp for illuminating the display room or in front of the display cabinet, especially the lighting lamp with a terminal at the end. Background technique [0002] Conventionally, a display case installed in a supermarket, a convenience store, etc. has a lighting lamp for illuminating the display room or the front of the display case, etc. installed in a display room formed in a main body. The lighting lamp is mounted on the lower surface of the ceiling located on the top front surface of the showroom, or at the front of the lower surface of the shelf when a plurality of shelves are erected. Since fluorescent lamps and the like are generally used as lighting lamps, they need to be replaced as they deteriorate over time. [0003] Each illuminating lamp installed in the showroom is connected to a power supply line connected to a power supply provided in the equipment room (see P...

AI Technical Summary

Problems solved by technology

[0009] However, since the socket main body provided on the main body side is fixed under the frame, the engagement between the fluorescent lamp holder on which the fluorescent lamp is mounted and the socket main body is performed at a position that is not easily recognized visually by the operator.

Therefore, when the fluorescent lamp holder is not properly engaged with the socket main body, the fluorescent lamp and the fluorescent lamp holder may easily fall off from the socket main body due to a slight impact or contact.

[0010] In addition, there is also a problem that poor contact between the terminal pins for receiving power and the power supply contact pieces occurs because the fluorescent lamp holder and the socket main body cannot be reliably engaged.

Such poor contact may lead to failure to ensure the lighting of the fluorescent lamp. Depending on the situation, the terminal pin or socket for receiving electricity may rise to an abnormal temperature and burn the terminal pin or socket.
