Description

Rotary switch structure

Technical field:

The utility model relates to a kind of rotary switch structure, be used for each electronic product, it forms several keepers and location notch in loam cake and rotating disk, and shell fragment is embedded in the below of turning, this guide plate forms several blocks and is coated in the pedestal, the stability that can provide multiloop conducting and control rotation accurately to distinguish and improve the quality by this when turning turn.

Background technology:

Along with the progress in epoch, accurate industrial development is rapid, and rotary switch also because of the market demand needs volume-diminished, as applies to computer, computer peripheral equipment, telecommunications, testing equipment, instrument and message product etc. in each electronic product part.

Because the conducting of dwindling this resistance of electronic component certainly will must have a preferable control, and its internal structure of existing product is very complicated, it is bigger to cause the thicker and shared area of the rotary switch assembled, cooperate with electronic product and rotary switch is many, and the rotation of turning that sees through rotary switch is with the different galvanic circles of conducting, the keeper that its inlay card is turned is located on the pedestal, and under long-time use, also produce flexible tired, and when turning turn, can't precisely fix, so gesture increases the fraction defective of spoilage and contact.

Edge this, the creator actively grinds the design of rotary switch deeply, the direction that it is considered as the designer with consumer's use orientation, right this utility model is exactly the setting and the shell fragment formation multiconductor of utilization keeper, can reach by this when making and have the conducting loop of multistage and make the inlay card more accurately of having turned, and the situation that reduces the loose contact rate produces with smaller volume.

The utility model content:

The technical problem that the utility model solved is: at above-mentioned the deficiencies in the prior art, provide a kind of rotary switch structure, with the stability that multiloop conduction mode is provided and improves the quality.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of rotary switch structure, this rotary switch includes at least that a loam cake, is turned, a shell fragment, a guide plate and a pedestal, one guide plate, this guide plate is a conducting material, and described loam cake is the rectangle lamellar body of an approximate ㄇ type, it is formed with several keepers corresponding to the periphery of turning, and encloses in the cuboid ring to form number button portion and embedding portion; Described turning is similar to a round disk body and is formed with several location notchs corresponding to the keeper place, places a side in ring again and wears a perforation, is formed with several cylinders on this is turned in addition; Described shell fragment, be the rectangle lamellar body of a peltate, and form a protuberance in a side, this protuberance is corresponding in the perforation of turning, wear in this shell fragment corresponding to perforation of a U type of above-mentioned cylinder of turning and number perforation, on the plane of this shell fragment, form again can with two contacts of described guide plate conflict conducting; Described pedestal is a rectangle block, and central part forms one for the circular depressions of turning and being placed in one, and forms several buckle ears and the several caulking groove that button portion and embedding portion for loam cake set fastening and enclose the longitudinal wall face in the cuboid ring.

So, this rotary switch form several keepers by loam cake and turn between form the number location notch, shell fragment forms two contacts and guide plate and compresses and touch in the plane, it is corresponding with the perforation that the side of turning is worn to reach a protuberance; Simultaneously count the guide plate of block by being coated on tool in the pedestal, not only can reduce the fraction defective of processing and the unsteadiness of quality, make it more can be firmly and fastening accurately and inlay card when turn, more can provide the conducting of multiple different circuit according to the needs in client loop.
