Abstract
The utility model relates to a small-angled ultrasonic sensor encapsulated rubber shell, which belongs to the ultrasonic sensor field, the inner part of the sensor encapsulated rubber shell is an empty cavity, a hole is positioned on the end surface of the sensor encapsulated rubber shell, and a slot is also positioned on the end surface of the encapsulated rubber shell; the slot is arranged in the center of the end surface of the encapsulated rubber shell, passes through the hole on the end surface of the shell and is symmetric with the center line; the width of the slot is less than or equal to the diameter of the hole on the end surface of the shell; a sensor probe is cooperated with the encapsulated rubber shell by a rubber sheath; the top surface of the probe and the end surface are in the same horizontal level; the utility model can locate a target accurately, the vertical detecting range is smaller but the horizontal detecting range is wider, the detectable range is much closer to the ideal model and much wider.
Description
Technical field
The utility model low-angle ultrasonic sensor packaging plastic shell belongs to the ultrasonic sensor field, particularly relates to a kind of ultrasonic sensor shell.
Background technology
Usually the performance improvement of ultrasonic sensor is mainly realized by structure that changes sensor package glue shell or the performance that improves sensor itself, because it is many to influence the performance factor of sensor, the sensor detectable range is generally all narrow, detectable range and ideal model differ certain distance, and particularly the structure at sensor package glue shell can have considerable influence to the performance of sensor with cooperating also of sensor.The sensor package glue shell of different structure has considerable influence for the performance of sensor.
Summary of the invention
The purpose of this utility model is to avoid weak point of the prior art and structure that a kind of sensor package glue shell is provided, makes the sensor detectable range more near ideal model, has wideer investigative range.
The purpose of this utility model reaches by following measure, by changing the structure of sensor package glue shell, make sensor package glue shell perfect with cooperating of sensor, reach the investigative range that enlarges ultrasonic sensor, ultrasonic sensor is made up of ultrasonic sensor packaging plastic shell and sensor probe, sensor package glue shell inside is cavity, a hole is arranged on the end face of sensor package glue shell, sensor probe is encapsulated in the cavity of sensor package glue shell inside by silicon rubber and plastic parts, sensor probe exposes from the hole on end face, on the end face on the packaging plastic shell, offered a groove, groove is opened in the middle of the end face of packaging plastic shell, groove penetrates the hole on the end face, and the center line symmetry is during installation, sensor probe effectively cooperates with the packaging plastic shell by rubber sleeve, the sensor probe end face is concordant with packaging plastic shell end face, and the rubber sleeve end face is concordant with the bottom surface of groove, forms a ring groove between sensor probe and the packaging plastic shell.After offering a groove on the packaging plastic shell, the installation direction of sensor is to adopt vertical the installation, makes the groove vertical ground of offering on the packaging plastic shell, and this also helps being avoided sensor ponding or dust stratification dirt.
Groove passes the end face of packaging plastic shell, forms two grooves of symmetry on the end face of packaging plastic shell.
The width of groove can less than or greater than the diameter in hole on the end face.
The end face shape of the shape in the hole on the end face on the packaging plastic shell and sensor probe is close.The shape in hole can be circular, also can be polygon.
The shape of packaging plastic shell end face can be circular, also can be polygon.
The utility model accurate positioning is visited the littler and level of vertical coverage and there is not scope wideer, and detectable range has wideer investigative range more near ideal model.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is example structure synoptic diagram of the present utility model.
Accompanying drawing 3 is end face synoptic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, the utility model sensor package glue shell 1 inside is cavity, a hole is arranged on the end face of sensor package glue shell, and the shape in hole is circular, and the shape of packaging plastic shell end face is a quadrilateral, on the end face on the packaging plastic shell, offered a groove, groove is opened in the middle of the end face of packaging plastic shell, and groove passes the hole on the end face, the center line symmetry, the degree of depth of groove is A, and gum cover 3 fixation of sensor probe 2 is in sensor package glue shell 1.
The utility model sensor probe is encapsulated in by silicon rubber and plastic parts in the cavity of packaging plastic shell inside, has offered a groove on the end face on the packaging plastic shell, and the degree of depth of groove is A.During installation, sensor probe effectively cooperates with the packaging plastic shell by rubber sleeve, and the sensor probe end face is concordant with packaging plastic shell end face, and the rubber sleeve end face is concordant with the bottom surface of groove, forms a ring groove between sensor probe and the packaging plastic shell.The width of groove is that the external diameter of B, sensor probe 2 is D, the width E of packaging plastic shell.
Claims (2)
1, a kind of low-angle ultrasonic sensor packaging plastic shell, sensor package glue shell inside is cavity, and a hole is arranged on the end face of sensor package glue shell, it is characterized in that having offered on the end face on the packaging plastic shell groove, groove is opened in the middle of the end face of packaging plastic shell, the center line symmetry.
2, low-angle ultrasonic sensor packaging plastic shell according to claim 1, the width that it is characterized in that groove be more than or equal to 3mm, and less than the width E of packaging plastic shell.
