The utility model content:

Technical problem to be solved in the utility model provides a kind of rotary coder, this scrambler is can implementation structure simple, compact, can be applied in the middle of the digital product, has finished the technical requirement that a scrambler is realized multiple function simultaneously.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of rotary encoder, one base is fixedlyed connected with shell, respectively is provided with a through hole on this base and the shell, and the two ends of whirligig cooperate this through hole to be arranged in the cavity of base and shell formation; Be provided with a shell fragment in the middle of base and this whirligig, this shell fragment is provided with sliding contact, and this sliding contact is with setting and stretch into three terminals that stretch in the base intracavity body that are provided with on the whirligig and contact the formation conversion of signals respectively; Be provided with a location spring leaf between this whirligig and the shell, be that the one end is fixed between base and the shell once the five metals spring leaf of mistake drawing, the arc salient point that other end arranged outside one is given prominence to, this salient point and some locating slots match, and constitute this rotary encoder.

Three exit terminals are fixedly mounted on chassis outer side, are the broach shape and arrange, and be respectively first, second connection point terminal and a shared connection point terminal.

A shell, be the support body of a five metals through punching press and bending, anti-stretching out on its central axis hole arc, and extend two intermediate plates downwards in both side edges, be used to detain base, be fixedly connected with base and form a space, extend an angle between two intermediate plates in addition, after this intermediate plate bends inwards, this scrambler finished product double team is fixed on the product.

Medial surface at whirligig is fixed with several locating slots that three equal circumference angular spacings are provided with.

In the both sides, side of this switch housing be extended with a pair of symmetrical support end, this support end is extended with a location step, terminal and this locating surface are provided with locating surface equally, can keep locating height and position, reservation and welding are decided to be the distance between the face, are setting and the use that cooperates with thin film switch.It is positive hexagon prism that this scrambler whirligig exposes rotating part.

Fig. 2 is the three-dimensional decomposition texture synoptic diagram of rotary encoder that the utility model provides;

Among the figure: the 1-base; The 2-shell; The 3-whirligig; 4-retainer spring sheet; The 5-terminal; The 6-shell fragment; The 7-button; The end of 8-button; The 9-thin film switch.

Embodiment:

As depicted in figs. 1 and 2: a kind of rotary encoder, be provided with gauge tap, it is characterized in that: a base 1 is fixedlyed connected with shell 2, this base 1 is provided with a through hole, and isogonism is provided with fan-shaped a pair of first, second connection point terminal and three shared leading-out terminals 5 that are the arrangement of broach shape in the base cavity; Three leading-out terminals 5 of scrambler are fixedly mounted on the base 1, and the circumference that contacted of five equilibrium sliding contact; A shell 2, be the support body of a five metals through punching press and bending, anti-stretching out on its central axis hole arc, and extend two intermediate plates downwards in both side edges, be used to detain base 1, be fixedly connected with base 1 and form a space, extend an angle between two intermediate plates in addition, after this intermediate plate bends inwards, this scrambler finished product double team is fixed on the product.By a whirligig 3, its rotating shaft two ends are installed in respectively on base 1 and the shell 2 on two coaxial circular holes in the space that base 1 and shell 2 form, and two coaxial circular hole actings in conjunction are in position, position rotating device 3 motion space; Whirligig 3 upper side equal circumference angular spacings also interconnect the sliding contact of the shell fragment 6 that conducts, and contact respectively with three terminals 5 in the base intracavity body, form conversion of signals; Medial surface at whirligig 3 is fixed with several locating slots that three equal circumference angular spacings are provided with, press close to this locating slot side and be installed with a retainer spring sheet 4, be five metals spring leaf once the mistake drawing, the one end is fixed between base 1 and the shell 2, the arc salient point that other end arranged outside one is given prominence to, this salient point and some locating slots match.Wherein the both sides, side of this switch housing 2 are extended with a pair of symmetrical support end, this support end is extended with a location step, terminal and this locating surface are provided with locating surface equally, can keep locating height and position, reservation and welding are decided to be the distance between the face, are setting and the use that cooperates with thin film switch 9.It is positive hexagon prism that this scrambler whirligig 3 exposes rotating part, can press down cylindrical button 7 in the adapted center, and the end 8 of this push button can directly contact matching used thin film switch 9 when doing pressing action, realizes the switching of function.
