Abstract

The utility model relates to a three convex point eight positioning coder which comprises a coder, a roller, a press shaft, a positioning plate of the roller, a switch and a basal plate. The utility model is characterized in that the coder is composed of a coder body, a folding and moving piece, a rotation base and a fixing bracket, wherein three groups of clamping position convex points are arranged on the rotation base, eight positioning grooves are arranged on the fixing bracket, the three groups of clamping position convex points are matched with the eight positioning grooves and the rotation base and the fixing bracket are clamped. Because the positioning grooves are arranged on the fixing bracket and the three convex points are arranged on the rotation base in the utility model, the original metal spring piece is replaced, the structure of the coder is simplified, the volume is cabinet and the cost is reduced.

Description

Three salient points, eight position encoder

Technical field

The utility model relates to a kind of scrambler, particularly a kind of three salient points, eight position encoder.

Background technology

Scrambler can be widely used in products such as AV equipment, general household electrical appliance and wireless telecommunications, as various level controls, tuning and timing setting usefulness.The scrambler of band roller and selector switch then extensively should be done page turning affirmation usefulness in computer mouse and small-sized digital product.The scrambler of existing band roller and selector switch as shown in Figure 1 and Figure 2, scrambler F is made of scrambler body A, folding mover B, revolving bed C, fixed support D etc.Its structure is that 24 teeth are arranged on revolving bed C, and must be equipped with a shell fragment K and its clamping, scrambler F rotates under the drive of roller G, each group folding mover B is in the contact chip E that adheres to different circuit separately respectively contact or contact condition not, thereby export electric signal.The opposite side of this roller G extends a last item H, the lower end of this last item H is provided with a runner location-plate I, the below of last item H end is provided with a switch J, in the time will doing the action of affirmation, depress roller G, make last item H downward together with roller G, the end of last item H promptly can contact the switch J that is located at its below, thereby forms the state (see figure 2) that opens or closes.The scrambler of this band roller and selector switch is widely used in the mouse structure.Under the situation that product is light, thin, short, little day by day now, the space of improvement is arranged still for reducing cost.

The utility model content

The purpose of this utility model be to provide a kind of simple and reasonable, volume is small and exquisite, lower-cost three salient points, eight position encoder.

The purpose of this utility model can reach by following measure: a kind of three salient points, eight position encoder, comprise scrambler, roller, last item, roller location-plate, switch, substrate, it is characterized in that: scrambler is made of scrambler body, folding moving plate, revolving bed, fixed support, revolving bed is provided with three groups of screens salient points, fixed support is provided with eight locating slots, three groups of screens salient points match with eight locating slots, make revolving bed and fixed support clamping.

The purpose of this utility model can also reach by following measure: also be provided with spacer between fixed support and revolving bed, spacer is provided with eight locating slots, and is corresponding with eight locating slots on the fixed support.The scrambler body is provided with the scrambler contact chip that strikes out predetermined number section and loop in advance, and clads same side in the scrambler body with plastics, constitutes the code device signal lead-out terminal.The folding moving plate is located between revolving bed and the scrambler contact chip, and is combined into one, and which is provided with the downward-sloping folding mover of predetermined group number.Revolving bed is provided with centration axis, is provided with hexagon ring in the centration axis.The fixed support bottom is provided with angle, and angle is arranged on the substrate.

The utility model has following advantage compared to existing technology: owing to be provided with three salient points on locating slot and the revolving bed being provided with on the fixed support, replaced original metal clips, so simplified the structure of scrambler, made its volume smaller and more exquisite, and reduced cost.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 5, the utility model is made up of scrambler 1, roller 2, last item 3, roller location-plate 4, switch 5, substrate 6 etc.Its structure and operating principle are same as the prior art, and difference is that the structure of scrambler 1 improves to some extent.

With reference to Fig. 3, Fig. 4, Fig. 6, scrambler 1 is made of scrambler body 7, folding moving plate 8, revolving bed 9, fixed support 10, spacer 14 etc., scrambler body 7 is provided with the scrambler contact chip 7-1 that strikes out predetermined number section and loop in advance, and clad same side in scrambler body 7 with plastics, constitute code device signal lead-out

terminal

11,12,13.Folding moving plate 8 is located between revolving bed 9 and the scrambler contact chip 7-1, and strikes out one; Which is provided with three groups of acclivitous folding mover 8-1, on scrambler contact chip 7-1, slide, make folding mover 8-1 contact or not contact by rotation roller 2 with scrambler contact chip 7-1, become output signal by its mistiming of causing and differential seat angle, and cause scrambler body 7 lead-out

terminal

11,12,13 outward, constitute the loop with the pcb board circuit.The opposite side of revolving bed 9 is provided with three groups of screens salient point 9-1; Spacer 14 is made of plastics, and which is provided with eight locating slot 14-1, and is corresponding with eight locating slot 10-1 on the fixed support 10; Three groups of screens salient point 9-1 are by eight locating slot 10-1 clamping on spacer 14 and the fixed support 10, and constituting back circles produces 24 stuck points, increases the serviceable life that spacer 14 can prolong this scrambler.
