Description
Technical field
The present invention relates to a kind of switch pushing method and switch, in more detail, relate to a kind of switch as last several millimeter of using such as mobile phones, form 3 balls that carry out switching manipulation more than 2, foremost ball is preferably 1,2 balls by next column are guided foremost 1 ball with the state of clamping, make stable switch pushing method of switching manipulation and switch.
Background technology
As the switch in the conventional art is the switch that same applicant proposes, 2 steel balls have been used in order to carry out switching manipulation, its structure such as Fig. 9 and shown in Figure 10, form recess by central authorities, and portion has the insulation shell 111 that the contact that possesses two-way contact 114 on a pair of shared contact 113a, 113b and the middle position is accommodated recess 112 within it; Be arranged on contact contiguously with a pair of shared contact 113a, 113b and accommodate 2 piece the 1st and the 2nd travelling contact plate 121a, 121b in the recess 112; Dividing plate 122 with the through hole 123 that only can connect one the 1st steel ball 131a size; The driver 131 that constitutes by 2 the 1st and the 2nd steel ball 131a, 131b; Has the cam part 141 that forms the cam surface 143 of wedge-like below one side of the 1st steel ball 131a contact; With 2 the 1st and the 2nd steel ball 131a, 131b key lever (key-stem) 151 to the pushing of cam part 141 directions; The cover portion 161 that covers the top of key lever 151 and cam part 141 constitutes.
Insulation shell 111 forms whole cubic by the synthetic resin of insulating properties, and the contact that forms opening is in the central accommodated recess 112.The cross section that this contact is accommodated recess 112 is for than bigger cylindrical of the profile of the 1st and the 2nd travelling contact plate 121a, 121b, and size can be housed in its inside loosely with the 1st and the 2nd travelling contact plate 121a, 121b.
Moreover, accommodate the bottom of recess 112 at this contact, on the face-off position, dispose shared contact 113a, 113b by inserting to be shaped, be provided with the two-way contact 114 that forms at the middle position that connects relative shared contact 113a, 113b with exposing.
The the 1st and the 2nd travelling contact plate 121a, 121b are with the conglobate structure of rubber-like metal plate shape, the shared contact 113a, the 113b that accommodate recess 112 with contact contact also loose chimeric, in order to make its center become the top of mild convex surface, from around crooked upward to form disc-shape.
Driver 131 is formed by 2 the 1st and the 2nd steel ball 131a, 131b, makes the 1st steel ball 131a in the place ahead pass through hole 123 and slightly to pressing down by the 2nd steel ball 131b at rear.
By each parts is set like this, as Figure 11 and shown in Figure 12, the guide path that formation is surrounded by cam connecting portion 153, the rear gathering sill 142 of cam part 141, cover portion 161, the dividing plate 122 of key lever 151, in this guide path, accommodated the 1st and the 2nd steel ball 131a, the 131b of the formation driver 131 that can move freely along guide path.
Because an end of guide path is communicated with the top of the 1st travelling contact plate 121a by the through hole 123 of dividing plate 122, thereby makes the part of the 1st steel ball 131a fall into through hole 123, docks with the top of the 1st travelling contact plate 121a.
The switch of this structure is not applying under the holding state shown in Figure 12 of operating physical force to key lever 151, because the 1st and the 2nd travelling contact plate 121a, 121b are that plate-like and top are crooked upward, two-way contact 114 separates with shared contact 131a, 131b.
From this state, holding when key lever rearward being pressed into action button 154, as shown in figure 13, key lever 151 rearward displacements are delivered on the 2nd steel ball 131b, and the 2nd steel ball 131b just pushes the 1st steel ball 131a.Because the 1st steel ball 131a docks with cam surface 143 as the inclined plane, the top of the 1st travelling contact plate 121a is depressed downwards, therefore, the vertical direction displacement of key lever 151 rearward shift transformations for the top of the 1st and the 2nd travelling contact plate 121a, 121b is depressed.
At this moment, because the 1st steel ball 131a docks with the top of the 2nd steel ball 131b, cam surface the 143, the 1st travelling contact plate 121a with the part of sphere, no matter be that rolling contacts or sliding contact all contacts in the mode of a contact, between them, big friction can not take place.In addition, because the key lever that is held in dividing plate 122 and the cover portion 161 and guided in the horizontal direction 151 docks with the sphere of the 2nd steel ball 131b by the interface of vertical direction, so can not be subjected to reaction force from the vertical direction composition of the 1st steel ball 131a, can not increase the sliding friction power with dividing plate 122 or cover portion 161, can with light work defeat into.
And, after the top with the 1st travelling contact plate 121a is pressed down to more than the certain value, because the 1st and the 2nd travelling contact plate 121a, 121b are the center counter-rotating with the top, the top of the bottom of the 2nd travelling contact plate contacts with two-way contact 114, by the 2nd travelling contact plate 121b two-way contact 114 and shared contact 113a, 113b raise are connect, two-way contact 114 and shared contact 113a, 113b conducting.
In addition, because when the 1st and the 2nd travelling contact plate 121a, 121b reverses, with respect to the increase of very little pushing force, the displacement of vertical direction increases sharp, as action button 154 transmission to key lever 151 of the timing of the variation of apparent pushing force.The the 1st and the 2nd travelling contact plate 121a during this counter-rotating, the variation of the displacement of 121b is also transmitted to key lever 151 by the 1st steel ball 131a and the 2nd steel ball 131b, but because the top of the 1st travelling contact plate 121a of contact the 1st steel ball 131a, cam surface 143, cover portion 161, key lever 151 and the 1st steel ball 131a are mutually to roll with the 2nd steel ball 131b and contact or the some contact, the friction that produces on these contact portions can not make the timing decay, the operator can obtain the 1st and the 2nd travelling contact plate 121a reliably, the sensation of the counter-rotating of 121b can recognize that the switch loop closes.
After this, after the push operation of releasing key lever 151, the 1st and the 2nd travelling contact plate 121a, 121b are because the elasticity of self is inverted to original shape once more, and key lever 151 also returns to state as shown in figure 12.Thereby the 2nd travelling contact plate 121b separates with two-way contact 114, two-way contact 114 and shared contact 113a, 113b insulation, and the switch loop is open.
Reverse at the 1st and the 2nd travelling contact plate 121a, 121b, when being about to recover, the elastic force that recovers to the vertical direction top also transmits to key lever 151 by the 1st and the 2nd steel ball 131a, 131b, but because each contact portion is with contact or the contact of some contact condition of rolling, can not decay, but be delivered on the key lever as the restoring force of forwards recovering owing to their friction.
