The invention belongs to the technical field of lamp holders, which resolves the problem that the existing lamp holder can not control make-and-break of a bulb with two independent tungsten filaments. A bipolar combined switch lamp holder core comprises a lateral surface contact blade (2) arranged on a holder body (1), a first wire connecting terminal (3) and a second wire connecting terminal (4), wherein the lateral surface contact blade (2) is connected with the first wire connecting terminal (3), the holder body (1) is equipped with a center contact electrode (5) and an eccentric contact electrode (6) which are electrically connected with a bulb, the holder body (1) is equipped with a rotating shaft (8) and an inner contact electrode (7) connected with second wire connecting terminal (4), the rotating shaft (8) is equipped with a four-tooth ratchet (9) which is equipped with a ratchet three-contact-blade body (10), and contacts of the center contact electrode (5), the eccentric contact electrode (6) and the inner contact electrode (7) are respectively sprung towards the back surface of the four-tooth ratchet (9). The invention has the function of multi-section changing-over combined switching, which is convenient in manufacturing, and fast and easy in assembly.
Description
technical field [0001] The invention belongs to the technical field of lamp holders. Background technique [0002] The existing lamp holder with a switch, the mouthpiece arranged on the base body, the center tongue, two electrical connection terminals, a rotary switch is provided on the lamp holder, and the rotary switch is connected in series with the center tongue and one of them is electrically connected. terminal. And existing a kind of bulb wherein is provided with two independent tungsten wires, and it has three contact electrodes, and its power is often very big, generally in hundreds of watts, and the electric current that passes through when energized work is very big, so the existing switch The base body cannot carry out on-off control to such bulbs. Contents of the invention [0003] The object of the present invention is to provide a bipolar combination switch lamp holder capable of on-off control of two independent tungsten filament bulbs, and capable of rea...
