Abstract
The invention relates to a manual control mechanism of a single-pole double-throw switch. The manual control mechanism of the single-pole double-throw switch comprises a control knob and a guide rotating shaft connected with the control knob, wherein on the guide rotating shaft, two gear parts are fixed parallelly and fixedly in the axial direction; the outline faces of the two gear parts are the same, and form closed continuous curved faces by concentric and different-radius arc sections which are connected end to end sequentially; and the mounting directions of the two gear parts meet the switching requirements of the single-pole double-throw switch.
Description
Technical field
The present invention relates to drive mechanism technical field, and in particular to a kind of manual control mechanism of single-pole double-throw switch (SPDT) and its
Manual single-pole double-throw switch (SPDT).
Background technology
The single-pole double-throw radio frequency coaxial switch that applies in the market, predominantly electromechanical, its operation principle be by outer
Portion is applied a voltage in coil, is produced electromagnetic force drive actions part, is realized the closed and disconnected of switch ways.
Both at home and abroad in electromechanical single-pole double-throw switch (SPDT), the conversion of electricity consumption magnetically-actuated switch is the universal side of microwave switch
Method.The main Types that class product electromagnetic system is adopted are kept at present to magnetic be " balanced armature is rotary " structure and " solenoid
Formula "." balanced armature is rotary " electromagnetic system is characterized in rotating shaft two ends armature part mass relative equilibrium, in severe machinery ring
Under border, the resultant couple of countershaft is the reliability under " zero ", it is ensured that severe mechanical environment, have the disadvantage that the leakage field of magnetic circuit system is larger,
The volume that the stroke of armature is less, the structure takes is larger." helix tube type " electromagnetic system advantage is that the utilization rate of magnetic is higher, magnetic
The leakage field of road system is all utilized, and the stroke of iron core is larger, and the structure takes small volume, is suitable for doing hilted broadsword more and throws product
Product, have the disadvantage that the quality of iron core is larger, larger to the reed impact for promoting, and iron core easily produces friction with the sleeve for coordinating, and sends out
Heat is serious.
Electromechanical single-pole double-throw switch (SPDT) is mainly used in surveying instrument, Auto-Test System and switch matrix etc., example
Such as vector network analyzer, Noise Factor Analyzer and TR component system etc..The advantage of electromechanical single-pole double-throw switch (SPDT) is to pass through
Control voltage signal realization is automatically switched, index is excellent, the repeated height of Insertion Loss.Have the disadvantage to realize in the case of power free
Switching, can be only applied to ATE.
Content of the invention
The present invention is in order to solve the above problems, it is proposed that a kind of manual control mechanism of single-pole double-throw switch (SPDT) and its manually list
Double-pole double throw switch.
To achieve these goals, the present invention adopts following scheme：
A kind of manual control mechanism of single-pole double-throw switch (SPDT), including control handle, the guiding rotating shaft being connected with control handle；Institute
State in guiding rotating shaft, abreast fix two gear parts vertically, it is characterised in that：The contoured surface of two gear parts is identical, all
Enclosed type continuous curve surface is constituted by the different arc section of the concentric being sequentially connected from beginning to end and radius；Described two gear parts
Installation direction meets the switching of single-pole double-throw switch (SPDT) and requires.
The gear part adopts cam structure.
The manual single-pole double-throw switch (SPDT) of a kind of knob, it is characterised in that also include drive mechanism；The drive mechanism includes
Two for being contacted with described two gear parts respectively are taken off post, and transmission column bottom connection flexible member, near transmission column top
It is fixed with movable contact spring；A push rod is fixed the movable contact spring two ends are each, the riveting of push rod end has transmission reed.
The flexible member includes spring or shell fragment.
The top for taking off post is cambered surface.
The top for taking off post is sphere.
Beneficial effects of the present invention：
（1）The action switching for switching can be realized under no electric situation or situation of shutting off power in emergency, and filled up electromechanical switch application
The blank of environment；
（2）There is no the situation of power-up heating, therefore there is longer service life；
（3）Manually knob controls the two-way break-make of single-pole double-throw switch (SPDT), simple to operate, reliability height；
（4）Transmission column top can be prevented in traditional switch using cambered surface or sphere, caused to lead to because Long Term Contact causes abrasion
The situation of road loose contact.
Description of the drawings
Fig. 1 is the overall structure figure of the manual single-pole double-throw switch (SPDT) of knob of the present invention；
Fig. 2 is the structure chart of gear cam of the present invention.
Wherein 1 gear cam, 2 movable contact springs, 3 push rods, 4 take off post, and 5 are oriented to rotating shafts, 6 control handles,
7 upper chamber covers, 8 springs, 9 inner conductor of radio frequency coaxial connector, 10 transmission reeds, lead outside 11 radio frequency (RF) coaxial connectors
Body.
Specific embodiment：
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
The present invention discloses a kind of manual control mechanism of single-pole double-throw switch (SPDT) first, including control handle, with control rotation
The guiding rotating shaft of button connection；In guiding rotating shaft, two gear cams are abreast fixed vertically：Two gear cams
Contoured surface is identical, by end to end first arc section successively（12）With the second arc section（13）Composition enclosed type continuous curve surface
（As shown in Figure 2）；First arc section（12）With the second arc section（13）Concentric and radius difference；Described two gears are convex
Wheel is reversely installed each other.
Present invention additionally comprises a kind of manual single-pole double-throw switch (SPDT) of knob, as shown in figure 1, including manual control mechanism and biography
Motivation structure.
Manual control mechanism mainly includes control handle 6, is oriented to rotating shaft 5, gear cam 1（2）, its middle gear cam is such as
Shown in Fig. 2.Two gear cams 1 differ 180 °, are fixed in guiding rotating shaft 5, realize when knob rotates 180 ° manual
The passage switching of switch.
Drive mechanism mainly includes movable contact spring 2, transmission reed 10, spring 8, push rod 3, take off post 4, upper chamber cover 7.Take off post
