Description
Technical Field
The utility model relates to a sensor field indicates a packaging structure of pressure sensor connecting piece especially.
Background
The sensor is a detection device which can sense the measured information and convert the sensed information into an electric signal or other information in a required form according to a certain rule to output so as to meet the requirements of information transmission, processing, storage, display, recording, control and the like. The sensor features include: miniaturization, digitalization, intellectualization, multifunction, systematization and networking. The method is the first link for realizing automatic detection and automatic control. The existence and development of the sensor enable the object to have the senses of touch, taste, smell and the like, and the object slowly becomes alive.
With the wide popularization of ceramic capacitive pressure sensors in the market, the ceramic capacitive pressure sensors are used in many occasions. Referring to the conventional pressure sensor shown in fig. 1, the conventional pressure sensor is electrically connected by a standard connector 1 (terminal) and a plug-in unit 2, and the waterproof rating thereof is generally I P65, but the disadvantage is that the waterproof rating is not high.
Disclosure of Invention
In order to solve the problem, the utility model provides a packaging structure of pressure sensor connecting piece can reach the waterproof grade of IP69, improves waterproof grade greatly.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a packaging structure of pressure sensor connecting piece, includes casing, connection end button, end button contact pin and connecting wire, connection end button lower extreme riveting is in the casing upper end, the connection end button is equipped with the upper end open-ended and holds the chamber, the end button contact pin sets up the intracavity that holds at the connection end button, the connecting wire lower extreme does not have the lead-tin welding with the end button contact pin, it is equipped with the casting glue to hold the intracavity, the casting glue covers the end button contact pin and extends to the connecting wire downside.
Furthermore, the pouring sealant covers the lower side of the connecting line by 0.5-1 cm.
Furthermore, the pouring sealant is an organic silicon resin pouring sealant or an epoxy resin pouring sealant.
Further, the pouring sealant is room temperature vulcanized silica gel or polyurethane pouring sealant.
Wherein, the surface of the connecting wire is wrapped by an insulating layer.
The beneficial effects of the utility model reside in that: after the terminal button contact pin and the connecting wire of the pressure sensor connecting piece packaging structure are welded by lead-free tin, pouring sealant is injected from the upper part of the connecting terminal button to seal the terminal button so as to form the packaging structure, the waterproof grade of IP69 can be reached, the waterproof grade is greatly improved, and meanwhile, the production cost is also reduced; by adopting the packaging structure, the sensor can be used in environments such as corrosion, dirt or water vapor, and the like, achieves very high protective performance, and is suitable for popularization and application.
