Description
Technical field
This utility model relates to rotary switch technical field, particularly to a kind of cassette rotary switch.
Background technology
Rotary switch is to control a kind of switch of main contacts break-make with rotary handle.The knot of rotary switch
Configuration formula has two kinds, is one pole unit structure and the many bit architectures of multipole respectively.One pole unit rotary switch
Often it is used in conjunction with rotary shaft potentiometer in the application, and multipole Multi-position rotation switch is used for work shape
The switching of state circuit.
Rotary switch can be used to replace the rotary pulsed generation of traditional resistive potentiometer analog functuion
Device, these rotary switches are typically used in instrument front console and the man machine interface of audio-visual panel, rotation
Turning on pass uses orthogonal optical encoder alternatively to simulate potentiometric pure digi-tal device.
Rotary switch structure in the market is complicated, easy to wear, and stability is not enough, and contact is bad,
Be inconvenient to use.
Utility model content
In order to overcome deficiency described above, the purpose of this utility model be to provide a kind of simple in construction,
Good stability, contact is good, safe and reliable cassette rotary switch.
The technical scheme in the invention for solving the technical problem is:
A kind of cassette rotary switch, wherein, including pedestal, axle sleeve, rotating shaft, guide post, cover plate,
Connecting card and conductive connecting piece, described axle sleeve is fixedly connected on described pedestal, the one of described rotating shaft
End is socketed in described axle sleeve, and the other end of described rotating shaft is through described cover plate with described guide post even
Connect, described cover plate be provided with contact terminal, described guide post respectively with described connecting card, conduction
Connecting sheet to connect, described conductive connecting piece is in above described connecting card, described connecting card sets
Put draw-in groove, described conductive connecting piece is provided with the first contact and the second contact.
As a kind of improvement of the present utility model, set between described connecting card and described conductive connecting piece
It is equipped with limit spring.
As further improvement of the utility model, described conductive connecting piece connects and has baffle plate.
In this utility model, axle sleeve is fixedly connected on pedestal, and one end of rotating shaft is socketed in axle sleeve,
The other end of rotating shaft is connected through cover plate with guide post, axis of rotation, drives guide post to rotate, thus
Making cover plate rotate, contact terminal thereon can be with the first contact or the second contact so that it is contact
Moderately good；This utility model simple in construction, good stability, contact is good, safe and reliable.
Accompanying drawing explanation
For ease of explanation, this utility model is made by following preferred embodiment and accompanying drawing to retouch in detail
State.
Fig. 1 is structural representation of the present utility model；
Reference: 1-pedestal, 2-axle sleeve, 3-rotating shaft, 4-guide post, 5-cover plate, 51-contacts
Terminal, 6-connecting card, 61-draw-in groove, 62-limit spring, 7-conductive connecting piece, 71-first touches
Point, 72-the second contact, 73-baffle plate.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with
Drawings and Examples, are further elaborated to this utility model.Should be appreciated that this place is retouched
The specific embodiment stated, only in order to explain this utility model, is not used to limit this utility model.
As it is shown in figure 1, a kind of cassette rotary switch of the present utility model include pedestal 1, axle sleeve 2,
Rotating shaft 3, guide post 4, cover plate 5, connecting card 6 and conductive connecting piece 7.
Axle sleeve 2 is fixedly connected on pedestal 1, and one end of rotating shaft 3 is socketed in axle sleeve 2, rotating shaft 3
The other end be connected with guide post 4 through cover plate 5, cover plate 5 is provided with contact terminal 51, guiding
Bar 4 is connected with connecting card 6, conductive connecting piece 7 respectively, and conductive connecting piece 7 is in connecting card
Above in the of 6, connecting card 6 arranges draw-in groove 61, conductive connecting piece 7 is provided with the first contact 71
With the second contact 72.
In this utility model, axle sleeve 2 is fixedly connected on pedestal 1, and one end of rotating shaft 3 is socketed in
In axle sleeve 2, the other end of rotating shaft 3 is connected through cover plate 5 with guide post 4, and rotating shaft 3 rotates, band
Action-oriented bar 4 rotates, so that cover plate 5 rotates, contact terminal 51 thereon can touch with first
Point 71 or the second contact 72 contact so that it is contact moderately good.
In this utility model, in order to, on more preferable rotating shaft 3, make the first of conductive connecting piece 7 touch
Point 71 preferably contacts with the contact terminal 51 on cover plate 5 with the second contact 72, connecting card 6
And it is provided with limit spring 62 between conductive connecting piece 7.
Further, in order to make the first contact 71 on conductive connecting piece 7 contact more with the second contact 72
Adding stable, conductive connecting piece 7 connects baffle plate 73.
The foregoing is only preferred embodiment of the present utility model, not new in order to limit this practicality
Type, all any amendment, equivalent and improvement made within spirit of the present utility model and principle
Deng, within should be included in protection domain of the present utility model.
