Description
Technical field
The present invention relates to sensor measurement member arts, specifically, be the accurate contact induction device of a kind of simple in construction.
Background technology
At present, in known contact induction device, most functions using complicated structure to realize sensing contact, after all
Its principle is physical quantity or chemical quantity to be transformed into the signal of telecommunication being easy to utilize, highly sensitive, can be suitable for and some superhigh precisions
Occasion, but its cost is high, when superhigh precision is not required for for some and impracticable；And in prior art
Contact induction device major part integration degree high, maintenance inconvenience, maintenance cost is high.
Summary of the invention
It is an object of the invention to provide the accurate contact induction device of a kind of simple in construction, it is achieved sensing contact function, and
Its precision is high, meets the user different demands to contact induction device.
The present invention is achieved through the following technical solutions: the accurate contact induction device of a kind of simple in construction, including shell, fixes
Detection module in the enclosure is installed, be movably arranged on shell in and part stretch out the contact of shell, it is characterised in that: detection mould
Block includes power supply, alarm and the switch being electrically connected by wire, and contact one end is fixing with switch to be connected.
Further, described switch include fixing with contact the shell fragment being connected fix with shell fragment one end be connected A conductor,
With the B conductor that shell fragment has gap, A conductor and B conductor are all connected in testing circuit.
In the present invention, owing to contact and shell are to be flexibly connected, contact one end contacts with object, and contact is subjected to displacement, with
Contact is fixed the shell fragment of connection and is subjected to displacement with contact, between the displacement of shell fragment is more than or equal between shell fragment and B conductor
During gap, switch Guan Bi, testing circuit turns on, and alarm sends alarm signal.
Further, the gap between described shell fragment and B conductor is between 0.1mm to 2cm.
Further, described contact stretches out one end of shell and is provided with conus portion.
Further, at described conus portion) larger diameter end be fixedly connected with back-moving spring, back-moving spring is fixedly mounted on
On shell.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) present invention uses the contact structure that be connected fixing with the switch in closed-loop path, it is achieved the function of sensing contact so that it is
Having simple and reasonable, input cost is low, advantage easy to maintenance.
(2), in the present invention, the gap arranged between switch shrapnel and conductor is between 0.1mm to 2cm, and switch only need to touch
Moving the displacement of 0.1mm to 2cm under the drive of head, circuit just can be connected, and displacement is little, and device sensitivity is high.
(3), in the present invention, contact stretches out one end of shell and is provided with the conus portion of taper, it is adaptable to some are fixed by endoporus
The demand of position detection, strengthens practicality.
(4) present invention is provided with returning spring, after being suitable for the most every time, the circuit of disconnection detection module, reduces power supply
Consume.
