Description

Packing structure of dry reed pipe sensor

Technical Field

Background

The reed switch sensor is mainly a sensor composed of a reed switch and an electromagnet. The reed pipe is composed of two reeds made of soft magnetic materials and packaged in a pipe shell, and pins which are connected with the reeds and led out from the pipe shell. Under the action of magnetic field, the reeds attract or separate from each other to realize the on-off of the circuit.

The existing reed switch sensor is usually wound with a foam pad outside the sensor and then placed in a carton for packaging and transportation, but after the foam pad is wound, the reed switch sensor placed at the bottom of a packaging box can be stressed, meanwhile, the reed switch sensor can still move relative to the carton in the transportation process, so that vibration or collision is easy to occur, and the reed inside the reed switch sensor can be bent or deformed by the aid of the stress and the vibration. Because the pipe shell of the reed pipe is a glass pipe shell and the reed inside is softer, when the reed pipe sensor suffers from vibration or collision in transportation, the reed inside the reed pipe is often bent or deformed, the distance between the two reeds is easily changed, and therefore the accuracy of the reed pipe sensor is reduced.

Under the action of the magnetic field, the reeds 31 attract or separate from each other to realize the on-off of the circuit. Because the tube shell 32 of the reed tube is a glass tube shell and the reed 31 inside the reed tube is soft, when the reed tube sensor encounters vibration or collision in transportation, the reed 31 inside the reed tube 3 is often bent or deformed, so that the distance between the two reeds 31 is changed, and the accuracy of the reed tube sensor is reduced. Meanwhile, vibration or impact can also cause the glass tube shell to break, resulting in direct rejection of the reed switch sensor. It should be understood that, since the engagement or disengagement of the two reeds in the reed pipe 3 is determined by the externally applied magnetic field, the external magnetic field required to close the two reeds 31 is changed by changing the distance between the two reeds 31. In an embodiment, when the original external magnetic field is supposed to close the reed 31 of the reed pipe 3, the external magnetic field cannot close the two reeds 31 because the two reeds 31 in the reed pipe 3 are far away from each other due to deformation, and the reed 31 is bent or deformed so that the reed pipe cannot accurately sense the change of the external magnetic field, that is, the accuracy of the reed pipe sensor is reduced.
