Double optical filter switcher without wire connection

Abstract

A double optical filter switcher without wire connection comprises a bottom shell, one end of the bottom shell is rotatably connected with a rocking handle, one end, close to the bottom shell, of the rocking handle is adhered with a magnet through glue, a surface cover is inserted into the top of the bottom shell, copper nuts are integrally injection-molded at the two ends of the surface cover, and the surface cover is divided into a thread part and a base part; the screw thread part and the base part are integrally formed in an injection molding mode, L-shaped grooves are formed in the top of the face cover, the number of the L-shaped grooves is two, the ends, penetrating through the L-shaped grooves, of the guide pins are welded to the copper nuts, and fixing glue adheres to the exposed positions of the guide pins. The circuit of the switcher is sealed in the internal space, so that short circuit caused by contact with the outside is reduced, and the problem of poor open circuit caused by scratching and pulling is effectively avoided; and the thread part of the surface cover and the base are integrated, so that the perpendicularity during product assembly is ensured, and meanwhile, the light leakage phenomenon caused by product assembly gaps can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of photographing equipment, in particular to a dual-filter switcher with wireless material connection. Background technique [0002] With the rapid development of imaging technology, the dual filter switcher can filter different light during day and night to prevent distortion during photography. [0003] The circuit of the existing dual-filter switcher is in contact with the outside world, which is likely to cause scratches and lead to a short circuit. In the existing device, the screws are directly threaded on the plastic, causing the screw holes of the product to slip and crack, and the product assembly gap is easy cause light leakage. Contents of the invention [0004] The technical problem to be solved by the present invention is that the screw in the existing device is directly threaded on the plastic, causing the screw holes of the product to slip and crack. The copper nut prevents the screw hole ...
