The utility model discloses ultrasonic sensor, its spliced pole length is great, does not need special instrument during with spliced pole fixed circuit board and U -shaped casing, and direct swivelling joint post can the fixed circuit board, installation convenient operation, work efficiency is high, and sealed apron through the fix with screw on the spliced pole, need not process the manufacturing cost of screw hole, reduction sensor that can be very big during the manufacturing on the U -shaped casing.
Description
Technical field
The utility model relates to a kind of sensor, particularly a kind of ultrasonic sensor.
Background technology
Ultrasonic sensor is the sensor utilizing hyperacoustic characteristic to develop.Ultrasound wave is the mechanical wave of a kind of vibration frequency higher than sound wave, is occurred to vibrate to produce by transducing wafer under the excitation of voltage, and it has, and frequency is high, wavelength is short, diffraction phenomenon is little, particularly good directionality, ray and the features such as direction propagation can be become.
The circuit board that the structure of ultrasonic sensor comprises housing, transmitter and receiver and is electrically connected with transmitter and receiver, housing is provided with mounting groove, and circuit board is fixed by screws in mounting groove, housing is also provided with the cover plate of sealing mounting groove; Detected material during work between receiver and transmitter will block receiver and receive the sound wave launched, thus sensor will produce switching signal.
Because circuit board and gland bonnet are all installed fixing by screw, screw number is more, needs special screw installation tool during installation, installs and comparatively wastes time and energy, and housing also needs the screw processing attachment screw, and the processing and manufacturing cost of housing is higher.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of ultrasonic sensor, there is to solve ultrasonic sensor of the prior art the technical matters that installation is wasted time and energy, processing cost is higher.
The utility model ultrasonic sensor, comprise the U-shaped housing be integrally made up of two horizontal rectangular columns and a vertical rectangular column, described two horizontal rectangular columns are respectively arranged with the mounting hole installing ultrasonic transmitter and ultrasonic receiver, described two horizontal rectangular columns are also respectively arranged with rectangle mounting groove, the circuit board be connected with ultrasonic transmitter and ultrasonic receiver is respectively provided with in described rectangle mounting groove, it is characterized in that: also comprise the joint pin be fixed on by circuit board on horizontal rectangular column, the lower end of described joint pin is connected with horizontal rectangle male screw, the upper end of described joint pin is provided with threaded hole, the notch of described rectangle mounting groove is provided with gland bonnet, described gland bonnet is fixed on joint pin by the screw coordinated with threaded hole.
Further, the notch of described rectangle mounting groove is provided with the recessed seam of location sealing lid.
Further, the bottom end of described mounting groove is provided with the boss of locating circuit board.
Further, described circuit board is provided with the connecting rod picking and placeing circuit board.
The beneficial effects of the utility model:
The utility model ultrasonic sensor, its joint pin length is comparatively large, and do not need special instrument with when joint pin fixing circuit board and U-shaped housing, the post that is directly rotatably connected gets final product fixing circuit board, and install easy to operate, work efficiency is high; And seal cover board is fixed by screws on joint pin, during manufacture, do not need thread mill drilling on U-shaped housing, the manufacturing cost of reduction sensor that can be very large.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present embodiment ultrasonic sensor.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the present embodiment ultrasonic sensor, comprise the U-shaped housing 1 be integrally made up of two horizontal rectangular columns and a vertical rectangular column, described two horizontal rectangular columns are respectively arranged with the mounting hole installing ultrasonic transmitter 2 and ultrasonic receiver 3, described two horizontal rectangular columns are also respectively arranged with rectangle mounting groove, in described rectangle mounting groove, are provided with the circuit board 4 be connected with ultrasonic transmitter and ultrasonic receiver respectively; Also comprise the joint pin 5 be fixed on by circuit board on horizontal rectangular column, the lower end of described joint pin is connected with horizontal rectangle male screw, the upper end of described joint pin is provided with threaded hole, the notch of described rectangle mounting groove is provided with gland bonnet 6, and described gland bonnet is fixed on joint pin by the screw 7 coordinated with threaded hole.
The present embodiment ultrasonic sensor, its joint pin length is comparatively large, and do not need special instrument with when joint pin fixing circuit board and U-shaped housing, the post that is directly rotatably connected gets final product fixing circuit board, and install easy to operate, work efficiency is high; And seal cover board is fixed by screws on joint pin, during manufacture, do not need thread mill drilling on U-shaped housing, the manufacturing cost of reduction sensor that can be very large.
As the improvement to the present embodiment, the notch of described rectangle mounting groove is provided with the recessed seam 8 of location sealing lid, by recessed seam, gland bonnet is positioned to the assembly working efficiency that can improve screw and threaded post.
As the improvement to the present embodiment, the bottom end of described mounting groove is provided with the boss 9 of locating circuit board, by boss, circuit board is positioned to the assembly working efficiency that can improve joint pin and U-shaped housing.
As the improvement to the present embodiment, described circuit board is provided with the connecting rod 10 picking and placeing circuit board, because rectangle mounting groove is darker, in installation process, circuit board is not easy to be in place, this improvement can easily pick and place circuit board by connecting rod, can be in place by circuit board faster, installment work efficiency is higher.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
