Abstract
The utility model discloses a capacitance proximity sensor with a conveniently fixed induction pole plate. The capacitance proximity sensor comprises a front cover, an induction pole plate and a signal processing circuit board arranged on the induction pole plate, wherein at least two axial through holes are arranged in the induction pole plate, fixed rods corresponding to the axial through holes and axially extending are arranged on the bottom wall of the front cover, penetrate through the axial through holes and are used for pressing the induction pole plate on the bottom wall surface of the front cover through fastening parts on end parts; and the fixed rods are plastic fixed rods, the fixed rods penetrate through the axial through holes, and the fastening parts are formed on the top ends of the fixed rods for pressing the induction pole plate on the front cover. The capacitance proximity sensor has the advantages of simple structure, capability of rapidly fixing the induction pole plate, easy operation and low cost.
Description
Technical field
The utility model relates to the industrial automation instrument industry field, is specifically related to capacitive proximity sensor.
Background technology
In the existing capacitive proximity sensor production run, the fixing general fixing mode of seccotine gummed that adopts of induction pole plate.Because seccotine production operation trouble is damaged non-bond site and appearance component easily, and is easy to generate albinism.So, bring labile factor for the quality of product.
The utility model content
The utility model technical matters to be solved just provide a kind of simple in structure, can fix fast the induction pole plate, easy to operate, respond to the capacitive proximity sensor of pole plate convenient fixing cheaply.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: the capacitive proximity sensor of induction pole plate convenient fixing; Comprise front shroud, induction pole plate and be installed in the signal processing circuit board on the induction pole plate; It is characterized in that: said induction pole plate is provided with at least two axial through bore; Said front shroud diapire is provided with the fixed bar that axially stretch out corresponding with said axial through bore, and said fixed bar passes said axial through bore and will respond to the diapire face that pole plate is pressed on front shroud through the fastening part of end.
Said fixed bar is the plastics fixed bar, and said fixed bar passes after the said axial through bore on the fixed bar top hot melt and forms the fastening part and will respond to pole plate and be pressed on the front shroud.
Preferably, said fastening part is mushroom-shaped structure or cylindrical-shaped structure.
As preferably, said fixed bar is circular or square, and said axial through bore be a corresponding circle or square.
As preferably, said front shroud is circular or square.
That the capacitive proximity sensor of the utility model has is simple in structure, can be fast to the induction pole plate fix, easy to operate, advantage that cost is low.Adopt the fixed technology of injection heat blow in addition, traditional relatively glue prescribed model is operated simplyr, convenient, can effectively improve the stability and the consistance of product quality, makes production technology simple and easy to do.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the blast structural representation of the utility model;
Fig. 2 is the assembly structure synoptic diagram of the utility model.
Embodiment
As shown in Figure 1, be the capacitive proximity sensor of the utility model induction pole plate convenient fixing, comprise front shroud 1, induction pole plate 2 and be installed in the signal processing circuit board 3 on the induction pole plate 2 that the induction pole plate is a copper induction pole plate.Said induction pole plate 2 is provided with at least two axial through bore 21; Said front shroud 1 diapire is provided with the fixed bar that axially stretch out 4 corresponding with said axial through bore 21, and said fixed bar passes said axial through bore and will respond to the diapire face that pole plate 2 is pressed on front shroud 1 through the fastening part of end.
As shown in Figure 2; Fixed bar described in the present embodiment is two plastics fixed bars; Fixed bar passes corresponding two axial through bore 21 backs and forms fastening part 41 at fixed bar 4 top hot melts and will respond to pole plate 2 and be pressed on the front shroud 1, after the induction pole plate is filled in the front shroud fixed bar, front shroud inwall and the maintenance of induction pole plate is compressed; Hot melt fixed bar 4 tops make it just to compress the induction pole plate, cool off to get final product after 5 seconds.Said fastening part is a mushroom-shaped structure, also can be various common structures such as cylindric.Said fixed bar is circular or square, and said axial through bore is the circular or square of correspondence, also can be other common structure.Certainly, the fastening part also can be parts such as the screw that cooperates with the fixed bar top, card cap; Said fixed bar also can for three or more than.
Except that above-mentioned preferred embodiment, the present invention also has other embodiment, and those skilled in the art can make various changes and distortion according to the present invention, only otherwise break away from spirit of the present invention, all should belong to the defined scope of accompanying claims of the present invention.
