Description

Electronic installation

Technical field

The utility model is relevant for a kind of electronic installation, and relevant especially a kind of relative displacement difference of the rotary slide switch of many gears of utilizing is finished multiple electric function conversion electronic device.

Background technology

See also Fig. 1.

Fig. 1 is the contact condition schematic diagram of expression known elasticity PAD contact-type.

Adopt directly with regard to the promotion shell fragment with regard to present slide switch is most, its mode is to contact execution by shell fragment and fixed contact.It is very responsive on the effect stroke, be generally+/-0.2mm, precompressed crosses at most also not that the pushing mechanism device just makes switch be in (ON) state, switch also is in (OFF) state even precompressed crosses at least that mechanism has finished whole pushing course.So this rotary slide switch of creation is finished this action, can save the production cost that product brings because of the precision surplus simultaneously, it is compact more to be fit to present handheld device, the trend that functional requirement is high.

After switch is contained on the machine, from X, Y, Z direction compression elasticity spare K, contact point C can take exercises in the horizontal direction, when arriving this contact point B, this contact point A be communicated with this contact point B and constitute the loop, but because its direction of error is a horizontal direction, and elastic component to produce the direction of action also be horizontal direction, the gap of causing because of made error and rigging error will occupy actuating length like this, and actuating length is diminished.Just the displacement of elastic component is required very highly and will overcome this problem, very accurate Stroke Control be arranged, require to use mechanism's part of this switch that very high precision will be arranged.And the manufacturing tolerance of general plastic parts is+/-0.1mm, the PCB foozle is+/-0.2mm, the SMT foozle is+/-0.05mm, error one accumulation like this, just have 0.45mm, much larger than the tolerance of this electronic installation, it is a large amount of bad that production line is produced in manufacture process.

Comprehensive above reason, why have so big error, mainly be because its precompressed direction and direction of action in one direction, so foozle can be occupied actuating length, so propose meter one slide switch, make its precompressed direction become 90 degree with direction of action, so just avoid foozle and actuating length overlapping.

The utility model content

In view of this, the purpose of this utility model is to provide a kind of electronic installation with rotary slip of many gears, by this to realize that small-sized hand held electrical equipment such as PDA, mobile phone are with the needs of slide construction as function switch.The structure system of this electronic installation can finish the conversion that realizes electric function with the relative position difference of mechanism element, not only simple in structure, compact reliable, easy for installation, and it is little to the relative positional accuracy susceptibility between two slide mechanism parts, except can reducing the production cost that product brings because of high accuracy significantly, more can be fit to the trend that present handheld device is compact, functional requirement is high.

Another purpose of the present utility model is to provide the conducting region with a fan type structure, even under the push effect that is subjected to side direction strength, remains on opening between two contacts that this conducting region still can be guaranteed to interconnect.

For reaching above-mentioned purpose, the utility model provides a kind of electronic installation that has, and this electronic installation comprises first pedestal, second pedestal, switching device shifter and elastic device.This first pedestal has at least the first contact and at least the second contact, this switching device shifter in the mode that can between first state and at least the second state, move at least adjacent to this first contact and this second contact, and this second pedestal can make this switching device shifter to move between this first state and this second state adjacent to this switching device shifter by the control of this second pedestal.This elastic device is arranged at this first pedestal, and this elastic device is contacted with on this switching device shifter.

This switching device shifter includes a conducting region, when this switching device shifter is positioned at this first state, this conducting region is this first contact of conducting and this second contact not, and when this switching device shifter is positioned at this second state, this first contact of this conducting region conducting and this second contact.
