Problems solved by technology

[0002] The existing grounding wires are generally fixed directly with screws or only use a pressure piece to compress the ground wires. The disadvantage is that the ground wires are easy to deviate from the screw column when the ground wires are fixed, and the ground wires are easy to rotate when the screws are tightened. Installation brings inconvenience; or directly install a round terminal on the end of the ground wire, and then fix the terminal with screws, the installation still has inconvenience, and it is not easy for the user to operate when replacing the ground wire

Abstract

The invention discloses a grounding device for a lamp, which comprises two grounding terminals and screws; the grounding terminal comprises a pressing piece and two limiting arms symmetrically arranged on the pressing piece. There is a through hole on the pressing piece, and the two limit arms are bent and extended towards the same side of the pressing piece; the screws pass through the through holes of the pressing piece of the two grounding devices in turn and are screwed with the threaded holes; the limit of the two grounding terminals The direction of the arms is opposite, and the pressing piece of one of the grounding terminals is located between the two limiting arms of the other grounding terminal; the ground wire is pressed tightly between the pressing pieces of the two grounding devices. The grounding terminals are used in pairs, the limit arms of the two grounding terminals are facing oppositely, and the grounding wires are pressed tightly by the pressing pieces of the two grounding terminals, which can effectively prevent the grounding wire from rotating away from the metal post during assembly, and realize the grounding wire and the metal post conveniently and quickly. The connection between the metal posts; at the same time, the contact area between the pressing piece and the ground wire is large, which can ensure the effective grounding of the lamp. At the same time, the invention also discloses a lamp using the above lamp grounding device.

Description

technical field [0001] The invention relates to a lighting device, in particular to a lamp and a grounding device thereof. Background technique [0002] The existing grounding wires are generally fixed directly with screws or only use a pressure piece to compress the ground wires. The disadvantage is that the ground wires are easy to deviate from the screw column when the ground wires are fixed, and the ground wires are easy to rotate when the screws are tightened. Installation brings inconvenience; Or directly install circular connection terminal at the end of ground wire, then this terminal is fixed with screw, still there is inconvenience in its installation, and user is difficult to operate again when changing ground wire. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a lamp and its grounding device with convenient and fast ground wire installation and firm and reliable ground wire connection. [0004] In ...
