Abstract
The utility model discloses an all-metal detection type inductive proximity switch comprising a housing, a plurality of groups of copper clad hollow coils arranged inside the housing, a circuit board provided with electronic devices, and an indicating lamp, wherein one end of the circuit board is connected with a wiring cable while the other end thereof is connected with the copper clad hollow coils, the indicating lamp is mounted on the circuit board, a top cover and a bottom cover of the housing both adopt plastic housings, and the housing main body adopts a metal housing. In the utility model, the arrangement of the copper clad hollow coils instead of magnetic powder core coils, accompanied by the improved housing, greatly extends the switch distance, and ensures faster reaction, more precise positioning, longer detection distance, stronger electromagnetic field interference resistance and longer service life, thereby realizing in a real sense the same detection distance to such metal as iron, aluminum, copper, brass and stainless steel.
Description
Technical field
The utility model relates to a kind of inductance approach switch, particularly a kind of to all-metal have the same detection distance near switch.
Background technology
Inductance approach switch be utilize conductive body can generate an electromagnetic field near this near switch the time make interior of articles produce vortex, when the transducer energized, the coil of oscillator produces an alternating magnetic field at the working surface of switch, when metal object during near the working surface of switch, metal produces eddy current and has absorbed the energy of oscillator, oscillator is weakened, so that stop.After metal object left, oscillator produced again.These two signals of the vibration of oscillator and failure of oscillation convert switching signal to by circuits for triggering, thereby play the control action of " leading to " and " breaking ".
Existing inductance approach switch, has caused at when measuring different detection distances being arranged near device, to bringing some inconvenience property of detection often to the difference of different its material behaviors of metal for different metals.
Summary of the invention
In order to overcome the problems referred to above, the utility model adopts and covers the copper hollow and organize coil more and increased the switch distance greatly, and a kind of inductance approach switch that identical detection distance is all arranged at all-metal is provided.
A kind of all-metal detection type inductance approach switch, it comprises shell, reaches the circuit board and the indicator light that the copper hollow is organized coil more, is provided with electronic device that cover of enclosure device, one end of described circuit board connects connection cable, the other end connects and to cover the copper hollow and organize coil more, described indicator light is installed on the circuit board, described closure head and shell bottom adopt plastic casing, and housing main body is a metal shell.
The circuit of described circuit board is connected in series by LC oscillator, circuits for triggering and output circuit and constitutes, and the wherein said copper hollow that covers is organized electronics device capacitor composition LC oscillator on coil and the wiring board more.
All-metal detection type inductance approach switch of the present utility model uses and covers the copper hollow and organize coil more, increased the switch distance greatly, full detection to various metal objects all has identical detection distance, overcome tradition near the difference of switch because of its various metal materials, when detecting the different metal object, the switch distance of its detection has decay, detect the inconsistent weakness of distance, because of its without the magnetic core coil, can prevent effectively that high-intensity magnetic field from disturbing, the utility model also has compact conformation, use and easy for installation, be swift in response, the location is accurate, extremely strong anti-electromagnetic field interference performance, the characteristics of long service life.

Embodiment
Below in conjunction with accompanying drawing to all-metal detection type inductance approach switch of the present utility model to further detailed description.
Be illustrated in figure 1 as structure chart of the present utility model, a kind of all-metal detection type inductance approach switch, it comprises shell 1, reaches the circuit board 3 and the indicator light 4 that the copper hollow is organized coil 2 more, is provided with electronic device that cover of shell 1 interior arrangement, one end of described circuit board connects connection cable 5, the other end connects and to cover the copper hollow and organize coil 2 more, described indicator light 4 is installed on the circuit board 3, and described closure head 11 and shell bottom 13 adopt plastic casing, and housing main body 12 adopts metal shell.
As Fig. 2 is circuit block diagram of the present utility model, and the circuit of circuit board 3 is connected in series by LC oscillator 32, circuits for triggering 33 and output circuit 34 and constitutes, and the wherein said copper hollow that covers is organized electronics device capacitor composition LC oscillator 32 on coil 2 and the wiring board more.Of the present utility model near after the switch energising, cover the copper hollow and organize LC oscillator 32 work that coil 2 becomes with electronics set of devices on the wiring board more, covering the copper hollow because of many groups organizes coil 2 more and produces magnetic fields and interact, detection faces 31 at transducer produces a plurality of alternating magnetic fields, when inspected object is close, the inner vortex flow that produces of the metallic object of inspected object has absorbed the energy that vibrates, and LC oscillator 32 quits work gradually.These two signals of the vibration of LC oscillator 32 and the failure of oscillations are triggered by circuits for triggering 33, convert switching signal output to by output circuit 34, can know understanding from the demonstration of indicator light, thereby play the control action of " leading to " and " breaking ".
All-metal detection type inductance approach switch of the present utility model, do not adopt used in the past magnetic core coil, employing is covered the copper hollow and is organized coil 2 more and increased the switch distance greatly, simultaneously, metals such as all-metal such as iron, aluminium, copper, brass and Stainless Steel all there is identical detection distance in conjunction with the interference that deperms of the improvement to shell 1.
