Background

According to the requirements of the light guide control panel specification MIL-DTL-7788H, four types of light guide control panels are light guide control panels in which small bulbs conforming to the relevant standards are used as light sources and wires of the small bulbs are embedded inside the light guide control panels. According to the above requirements, the small bulb and the wire serving as the light source need to be embedded into the light guide control panel, namely the light source and the wire cannot be higher than the back of the light guide control panel, a wire groove and a lamp groove are generally formed in the back of the light guide control panel, the small bulb and the wire are installed and then sealed in the light guide control panel by using sealant, and the small bulb and the wire become an integral body with the light guide control panel and cannot be detached.

The four types of light guide control panels have special requirements on light color, a light source small bulb needs to be provided with a filtering cap for light color adjustment, according to the manufacturing process of a common light guide control panel, paint is needed to adjust the brightness of the panel, the light chromaticity is tested after the brightness meets the requirements, and the filtering cap in a light chromaticity disqualified area needs to be adjusted if the test is disqualified. However, the light guide control panel is already sealed when the brightness of the light is adjusted, and the light source of the light guide control panel only comprises a conducting wire and a small bulb, and the light guide control panel cannot be well fixed in the panel without being sealed by a sealant, namely the panel cannot be lightened. When the light color is adjusted, the sealed panel can only be disassembled again, and the panel is sealed again after the adjustment is finished. Repeated dismouting has not only reduced production efficiency but also has adverse effect to product stability.

The utility model discloses in, countersunk screw's quantity is two, all installs inside the counter sink.

The utility model discloses in, PCB is the single face copper-clad plate to covering copper in certain area and removing, non-covering copper face has two counter bores, PCB divide into about two regions, and control insulating, PCB groove at PCB and the light guide control panel back adopts clearance fit.

The utility model discloses in, the light guide control panel material is aviation organic glass.

The utility model discloses in, the small bulb has two contacts, welds respectively PCB covers copper face left side region and right side region.

To sum up, the beneficial effect of this application: through the structural design of the main components, the problem that the small bulb is difficult to frequently disassemble when the light chromaticity of the light guide control panel is adjusted in the production process is properly solved, the production efficiency is improved, the stability of the whole structure is ensured, and abnormal contact of the contact due to frequent disassembly is avoided.
