A polymer film sensor

Abstract

The invention belongs to the technical field of sensors, specifically a polymer film sensor, including a sensor body, a connector, a metal contact, a protective cylinder, a semicircular plate, a pull cord, a fixed block, a spring, a moving block, a screw, a rubber Plug, protective cover, metal block, spring two, pull rod, groove and square magnetic frame. The movement of the screw rod of the present invention drives the movement of the rubber plug, and the movement of the protection cylinder makes the connecting head squeeze the semi-circular plate, the semi-circular plate is squeezed and rotates around the hinge, the rotation of the semi-circular plate drives the movement of the pull cord, the movement of the pull cord drives the movement of the moving block, and the movement of the block The movement compresses the spring one, the elastic force of the spring one facilitates the automatic reset of the semicircular plate, the movement of the pull rod drives the metal block to move, the square magnetic frame absorbs and fixes the metal block, the metal block moves to compress the spring two, and the protective cover is installed on the sensor On the main body, the pull rod drives the metal block to move, and under the action of the second elastic force of the spring, the metal block enters the limit hole to realize the installation of the protective cover.

Description

technical field [0001] The invention belongs to the technical field of sensors, in particular to a polymer film sensor. Background technique [0002] A sensor is a detection device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, and display. , recording and control requirements. [0003] The currently used sensors have certain defects, such as the lack of connector protection function. During the transportation of the sensor, the connector is exposed, and the connector is easily damaged by collision, which is inconvenient for the use of the sensor body. At the same time, it lacks the anti-deformation function of the metal contact. Metal contacts are easily deformed by impact, which is inconvenient for the sensor body to be connected to the circuit to be connected. In view of th...

Problems solved by technology

[0006] The purpose of the present invention is to provide a polymer film sensor in order to solve the above problems. The present invention can be twisted by adding a protective tube, a semicircular plate, a stay cord, a fixed block, a spring, a moving block, a screw rod and a rubber stopper. Screw, the screw rotates and moves along the threaded hole, and the movement of the screw drives the rubber plug to move. When the rubber plug is detached from the inner hole of the connector, the user pulls the protection cylinder, and the movement of the protection cylinder makes the connector squeeze the half-circle plate, and the half-circle plate is Extrusion rotates around the hinge, the rotation of the semicircular plate drives the movement of the pull cord, the movement of the pull cord drives the movement of the moving block, and the movement of the moving block compresses the spring. Once the spring is compressed, it generates elastic force. The elasticity of the spring facilitates the automatic reset of the semicircular plate. It is easy to rotate and the protective tube falls off from the connector, which solves the problem of the sensor currently used. It lacks the protection function of the connector. During the transportation of the sensor, the connector is exposed, and it is easy to cause damage to the connector due to collision, which is inconvenient for the main body of the sensor. The problem of use, the present invention adds protective cover, metal block, spring two, pull rod, groove and square magnetic frame, pulls pull rod, pull rod moves and drives metal block to move, and metal block moves into groove interior and fits with square magnetic frame, The square magnetic frame absorbs the metal block, stores the metal block in the groove, moves the metal block to compress the second spring, and the second spring is compressed to generate elastic force, and then the user installs the protective cover on the main body of the sensor, so that the groove and The limit holes are aligned, and then the user pushes the pull rod, which drives the metal block to move and separate from the square magnetic frame. Under the action of the second elastic force of the spring, the metal block enters the limit hole, thereby realizing the installation of the protective cover, which solves the current problem. The sensor lacks the anti-deformation function of the metal contact. The metal contact is easily deformed by collision, which is inconvenient to connect the sensor body to the circuit to be connected, and reduces the practicality of the sensor body.
