Description

Electrical connection device and luminaire applying the same

The present invention relates to an electrical connection device, and more particularly to an electrical connection device for a luminaire and a luminaire to which the electrical connection device is applied. Background technique

If the lamp is to be mounted on a mounting surface such as a wall or a supporting plate, the installer must first connect the power cable electrically connected to a power supply and the power wire in the mounting surface to the electrical wire inside the lamp. After the luminaire can receive the power supply of the power supply, the luminaire can be fixed on the installation surface to complete the installation work of the luminaire. However, the wiring process between the electrical wires and the power wires in the lamp is rather cumbersome, and the installer must also support the lamp while the installation operation is rather cumbersome and difficult.

In view of this, all parties are committed to the development of an easily installable luminaire, such as the luminaire disclosed in Japanese Patent No. 4,916, 682, which is provided with a female connector connected to the power supply wire at the mounting surface end, when the luminaire is to be installed. When installing the surface, the male connector is first extended into the female connector and rotated, so that it can be electrically connected to the female connector in a contact manner, and then the lamp body and the male connector of the lamp are connected. In combination, the main body of the lamp can be electrically connected to the power supply end, thus completing the installation work of the lamp.

Furthermore, the male connector is provided with an extension portion exposed to the side, an operation portion provided on the bottom surface, and a restriction portion provided on the side, and the installer can retract the extension portion into the male connector by operating the operation portion. At this time, the installer can simply fix the main body of the lamp through the male connector and then extend the outer portion of the lamp to be externally exposed, so that the lamp body of the lamp can be fixed between the extension portion and the mounting surface; The installer only needs to operate the restriction portion so that the extension portion is restricted from being retracted, thereby ensuring that the lamp body and the male connector can be firmly coupled to avoid easy retraction when the extension portion is accidentally touched or accidentally hit, resulting in the lamp body. The structure is detached from the male connector.

However, when the installer wants to pass the luminaire body of the luminaire through the male connector, the operator must be operated with one hand while the other hand holds the luminaire body and moves it toward the mounting surface to pass through the male connector. In addition, since the restriction portion and the operation portion are two independent components, it is difficult for the installer to operate the restriction portion and the operation portion at the same time, so that the extension portion after the outward extension cannot be restricted in the current state. Shrinking, this has become a major flaw in the design.
