Technical field
The utility model relates to a kind of encoder component, a kind of encoder component that the signal of scrambler is transmitted through opto-electronic conversion of more specifically saying so.
Background technology
Scrambler (encoder) is that signal (like bit stream) or data are worked out, converted into can be in order to communication, transmission and signal stored form of device.Scrambler converts angular displacement or straight-line displacement to electric signal; The former is called code-disc; The latter is called yardstick. can be divided into contact and contactless two kinds according to the playback mode scrambler. and contact adopts brush output, and brush contact conduction region or insulation layer represent that the state of code is " 1 " or " 0 "; The contactless sensitive element of accepting is light activated element or magneto sensor; When adopting light activated element with photic zone and light tight district represent the state of code be " 1 " still " 0 ", the binary coding through " 1 " and " 0 " converts the physical signalling of collection into electric signal that machine code can read in order to communication, transmission and storage.
Scrambler is widely used in industrial control fields such as measuring position, speed or angle.But because the medium of: 1 transcoder signal is concentric cable or twisted-pair feeder at present,, receive strong electromagnetic interference (EMI), have potential safety hazard to a great extent because scrambler is common and motor links together.
Yet, lack in the prior art and a kind ofly can code device signal be transferred to the encoder component product on the main circuit board reliably.
The utility model content
The purpose of the utility model is to overcome the defective of prior art, provides a kind of and can code device signal be transferred to the encoder component on the main circuit board reliably.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of plastic optical fiber type encoder component comprises the scrambler that is connected with main circuit board, also comprises the receiver module that is connected with main circuit board, the forwarding module that is connected with scrambler, and is used to connect the plastic optical fiber of forwarding module and receiver module.
Its further technical scheme is: also comprise the power lead that is used to connect forwarding module and receiver module.
Its further technical scheme is: also comprise the protective casing that is connected between forwarding module and the receiver module, be provided with aforesaid power lead and plastic optical fiber in the described protective casing.
Its further technical scheme is: described power lead is two, and described plastic optical fiber is one.
Its further technical scheme is: described scrambler is a rotary encoder.
Its further technical scheme is: described scrambler is incremental pulse encoder or absolute type pulse encoder.
Its further technical scheme is: also comprise metal shell, be provided with aforesaid scrambler and forwarding module in the described metal shell.
The utility model beneficial effect compared with prior art is: the utility model adopts plastic optical fiber as medium; The signal of scrambler is through electricity-light conversion; The receiver module that can carry out the conversion of light-electricity in the main circuit board increase adopts light signal to come the: 1 transcoder signal between wherein, makes signal in transmission course, not receive any electromagnetic interference (EMI); X-over adopts the metal shell shielding measure, has guaranteed the reliability of code device signal transmission.The utility model plastic optical fiber type encoder component can be widely used in industrial control fields such as measuring position, speed or angle, need be than the product of longer transmission distance such as being used for elevator, track traffic etc.
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
