Embodiment Construction
[0017] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0018] see Figure 1 to Figure 3 , the present invention provides a structure of an electric shock-proof lamp cap, including a lamp cap shell 1, a threaded inner bush 2, an insulating plate 3, a copper post 4, a positive contact 5, a negative contact 6, a spring 7, a terminal screw 82, and a terminal 81. Lamp holder base 9 and lamp holder 10.
[0019] Lamp cap shell 1, the lamp cap shell 1 is cylindrical, and two wiring holes are opened on the bottom of the tube of the lamp cap shell 1. In this embodiment, a cylindrical groove 11 is provided at the center of the bottom of the lamp housing 1 , and the other end of the positive electrode contact piece 5 is located in the cylindrical groove 11 . The effect of the cylindrical groove 11 is to limit the spring 7, and...

The invention discloses an electric-shock preventive lamp base structure which comprises a lamp base shell, a threaded lining sleeve, an insulating plate, a copper column, an anode contact piece and a cathode contact piece. The threaded lining sleeve is fixed into the lamp base shell, the top of the threaded lining sleeve is separated from a barrel bottom of the lamp base shell, and a first notch is formed in a side of the threaded lining sleeve; the insulating plate is lapped on the top of the threaded lining sleeve, an accommodating space is enclosed by the insulating plate and the lamp base shell, an anode connecting through hole is formed in the center of the insulating plate, and a cathode connecting notch which corresponds to the first notch is formed in a side of the insulating plate; the copper column comprise a copper column body and a limiting portion, the limiting portion is positioned on the copper column body and divides the copper column body into an upper end and a lower end, and the lower end of the copper column body downwardly penetrates the anode connecting through hole formed in the insulating plate. The electric-shock preventive lamp base structure has the advantages that the copper column can move, so that contacts can move; the copper column is not in contact with the anode contact piece when a bulb is not arranged in the lamp base structure, accordingly, the inside of a lamp base is not powered on, electric-shock accidents can be prevented, and the personal and property safety of users can be guaranteed.
Description
technical field [0001] The invention relates to a lighting fixture, in particular to an anti-shock lamp base structure and a lighting fixture. Background technique [0002] Most of the lamp holders in the prior art have no protective structure, and the user easily touches the contacts in the lamp holder when replacing the light bulb or maintaining the lamp, thereby causing electric shock, causing accidents, and resulting in personal and property losses. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the above-mentioned prior art, and propose an electric shock-proof lamp base structure and a lamp, the electric shock of the electric shock-proof lamp base structure and the lamp is a movable contact, which avoids the danger of electric shock for the user . [0004] In order to solve the above-mentioned technical problems, the present invention proposes an electric shock-proof lamp base structur...
