Description

Contact zero-friction multi-point circuit switching device

The utility model relates to a kind of contact does not have friction multipoint circuit switching device shifter, is applicable to communication, control automatically, instrument and meter for automation, electronics and electricly wait the multipoint circuit switching.

The multipoint circuit switching device shifter is more both at home and abroad at present, and as mechanical type stepper, band switch, they exist the contact abrasion, useful life is short, responsiveness is slow, switching point reaches bulky shortcoming less.By the multiple spot switching device shifter that reed switch relay is formed, though switching point is many, form by more reed switch relay and circuit element, exist that volume is big, cost is high and the shortcoming of complex circuit.89200021.X patent disclosure a kind of contact do not have friction multipoint circuit switching device shifter.The fixed contact of this multipoint circuit switching device shifter is circular noseplate, and moving contact is located at by coil crosses on the cross movement arm that armature can lift for the electromagnet excitation magnetic flux.When circuit switches, electromagnet coil power, the magneticaction of electromagnet lifts moving contact in armature under the drive of cross movement arm, and stepping motor work drives moving contact and arrives the circuit switched of setting.Stepping motor stops, and moving contact contacts with fixed contact under the effect of spring, realizes that contact does not have the friction circuit switched.Solve contact abrasion, circuit switched and reached shortcomings such as volume is big less.But because this multiple spot circuit switched device is provided with the circular noseplate of fixed contact, it is many to switch the multipoint circuit wiring, if multipoint circuit is arranged and connect, as the matrix wiring, just can not once corrode with printed substrate, can only be welded into ground of single cord, workload is big, and speed of production is slow, and the many wiring of line intersect mixed and disorderly, poor reliability, plug connector is many, the cost height.Because fixed contact is a circle distribution, then switching point is a fixed number again.

Task of the present utility model provides the contact that a kind of wiring is simple and easy, neat, workload is little, the raising speed of production reduces cost does not have friction multipoint circuit switching device shifter.

For realizing above-mentioned task, technical solution of the present utility model is: spring, armature, electromagnet and moving contact are contained on the movement parts.Fixed contact is located on the printed substrate.On one side of this printed substrate the driving-belt tensioner pulley that drives the movement parts walking is housed, stepping motor is housed, the guide of movement parts is housed therein at its another side.Movement parts is located at pulley and is contained on the driving-belt between the drum on the step motor shaft.

Because above-mentioned technical solution fixed contact is located on the printed substrate, moving contact does reciprocating linear motion, and makes circular motion than the moving contact of prior art, and fixed contact is that circular noseplate has many good qualities, and has solved the deficiencies in the prior art.Make circuit switched wiring simple and easy neat, reduce workload, boost productivity, reduce cost, switch count change easily, reduce plug connector etc.

The utility model is described in further detail below in conjunction with drawings and Examples.
