The utility model content
The problem that the utility model need solve be at exist in the mouse scrambler to manufacture process requirement height, the high deficiency of production cost, a kind of reliability height, perforation shaft encoder that production cost is low are provided.
The utility model is achieved through the following technical solutions: a kind of perforation shaft encoder, comprise pedestal, shell, rotor, transfer strip and spacer, have the perforation that connects on pedestal, shell and the rotor, transfer strip, rotor and spacer are installed in base interior from down to up successively, shell is fixed on the pedestal, and transfer strip, rotor and spacer are sealed in the pedestal.The scrambler shell is provided with fixing feet, is used for scrambler fixing in the circuit board.Base bottom surface central authorities are provided with one group of endless metal contact that is connected with a signal output terminal, two groups of hard contacts that are connected with a signal output terminal respectively are set in the periphery of central annular hard contact, these two groups of hard contacts form a discontinuous annular, and the hard contact of central annular or peripheral annular is provided with the insulator breach; Transfer strip is the lamellar body of an annular, its first-class branch is provided with three haptic elements, and this transfer strip one end is provided with riveted holes, is riveted on the riveting column at the rotor back side, the other end is provided with the metal haptic element, this metal haptic element and described hard contact and the sliding contact of insulator breach.Described insulator breach is arranged on peripheral two groups of hard contacts, and the metal haptic element on the transfer strip is divided into two legs, a leg contacts with the central annular hard contact, another haptic element contacts with the hard contact of peripheral discontinuous annular, two pairs of transfer strips are oppositely arranged, rotate with rotor but work as transfer strip, the leg priority of transfer strip contacts with the hard contact on the peripheral circumferential; Rotor continues rotation, and the leg while of transfer strip contacts with the hard contact on the peripheral circumferential; Rotor rotates once more, and the leg priority of transfer strip disconnects with the hard contact on the peripheral circumferential.Transfer strip back and forth rotates with rotor, the output make-and-break signal.
Connect on the shaft encoder metal shell and have through hole, can shell be fixed on the pedestal by riveted way or the mode that is threaded.When for the riveted joint mode fixedly the time, opposite position is provided with projection on described pedestal, and this projection is the rivet place; When fixedly the time, being provided with the threaded hole that is complementary at described pedestal opposite position by thread connecting mode.Be provided with reinforcement on signal output terminal, this reinforcement is pyramid shape or xsect is scalariform.
The beneficial effects of the utility model are: because the existing shell that connects shaft encoder adopts metal material to make, metal shell generally adopts the mode of bending fastening, need use more metal material.And dash the waste that material easily causes material, along with the rise day by day of metal supply requirement amount, metal price is also surging thereupon, causes production cost high.After perforate on the shell of scrambler, shell and pedestal are used the riveted joint mode instead or thread connecting mode is fixed, so manufacture difficulty reduces, and reduced technology and saved material, and reliability further guaranteed, have reduced production cost.On signal output terminal, increase reinforcement, make signal output terminal intensity improve, be not easy bending, and can suitably reduce thickness, reduced the use amount of material, further reduced production cost owing to increased the reinforcement signal output terminal.
