Description
Technical field
The utility model relates to sensor technical field, relates in particular to a kind of inductance type proximity transducer.
Background technology
The inductance type proximity transducer is a kind of position transducer of non-cpntact measurement; Be to utilize eddy current effect to control the starting of oscillation and the failure of oscillation two states of high frequency oscillator; Realization is to the detection of position quantity; And convert it into the output of electric switch amount, thereby realize the control of load or the conversion and the transmission of signal.It has reliable operation, stable performance, repetitive positioning accuracy high, do not have mechanical wearing and tearing, long service life, no-spark, noiselessness, outstanding advantage such as antijamming capability is strong, environmental suitability is strong.The most volume of existing inductance type proximity transducer is big, seems disorderly on the structural arrangement, and it is not very tight making each parts be connected, and can damage or pull apart when mounted like the connecting line of circuit board and power supply.Thereby make inductance type proximity transducer inconvenient installation, production efficiency is low and stable low.
Summary of the invention
Therefore, to above-mentioned problem, the utility model proposes a kind of compact conformation, uses with easy for installation, and production efficiency is high, accurate positioning, the inductance type proximity transducer that the life-span is long.
For solving this technical matters; The utility model is taked following scheme: a kind of inductance type proximity transducer; Comprise the cylinder blanket magnetic core inner, be surrounded on coil and the circuit board that is connected with magnetic core electric wire on the magnetic core with being arranged at cylinder blanket; Said coil and the electronic component electric capacity on the circuit board that is surrounded on the magnetic core is formed a LC oscillator; Said cylindrical housings inside is positioned at the end that coil and magnetic core are set and is provided with holder, and said circuit board is located on the holder removably.
Further, said holder be provided with one with the suitable groove of circuit board thickness, circuit board is removable to be located on the groove.
Further, the circuit of said circuit board is made up of LC oscillator, trigger circuit and output circuit series connection, and the output terminal of said output circuit connects external unit.
Further, said cylindrical shell surface is provided with screw thread.
Through adopting the aforementioned techniques scheme, the beneficial effect of the utility model is: through circuit board is fixed on the holder, make the connecting line of circuit board and power supply conveniently weld, and easy damaged is not perhaps pulled apart; Simple and compact for structure, make things convenient for production and assembly and use, enhance productivity; Stability is higher, accurate positioning, long service life.
Description of drawings
Fig. 1 is the utility model embodiment one-piece construction synoptic diagram;
Fig. 2 is that the utility model embodiment cuts structural representation open.
Embodiment
Combine accompanying drawing and embodiment that the utility model is further specified at present.
With reference to figure 1, Fig. 2; A kind of inductance type proximity transducer of the utility model embodiment; Comprise the cylinder blanket 1 magnetic core 2 inner, be surrounded on coil 3, the circuit board 4 that is connected with magnetic core 2 electric wires on the magnetic core 2 and be located at cylindrical housings inside and be positioned at the holder 5 on the end that coil and magnetic core are set with being arranged at cylinder blanket 1; The said coil 3 that is surrounded on the magnetic core 2 is formed a LC oscillator with the electronic component electric capacity on the circuit board 4, and said circuit board 4 is located on the holder 5 removably, promptly said holder 5 be provided with one with the suitable groove of circuit board 4 thickness; Circuit board 4 removable being located on the groove; Said circuit, 4 circuit is made up of LC oscillator, trigger circuit and output circuit series connection, and the output terminal of said output circuit connects external unit.Said cylinder blanket 1 surface is provided with screw thread 11.
The utility model make the connecting line of circuit board and power supply conveniently weld, and easy damaged is not perhaps pulled apart through circuit board is fixed on the holder; Simple and compact for structure, make things convenient for production and assembly and use, enhance productivity; Stability is higher, accurate positioning, long service life.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; The those skilled in the art should be understood that; In the utility model spirit that does not break away from appended claims and limited and scope; Can make various variations to the utility model in form with on the details, be the protection domain of the utility model.
