Embodiment Construction

[0013] The present invention will be clearly and completely described below in conjunction with specific embodiments.

[0014] A method for fabricating a sensor structure, comprising the steps of:

[0015] Stamping forms a metal sheet body, and metal pins are formed on the formed metal sheet body. Before stamping, the metal material at the metal pins is pre-plated, so that after punching, a tin-plated layer is formed on the pins of the number of pieces, so A connection area is formed on the upper surface of the metal sheet; the two metal sheets are symmetrically arranged in the injection mold, and a set distance is left between the two metal pins; a sensing element is provided, and the sensing element Set on the two pins, and connect the end of the sensing element to the tin-plated layer on the corresponding metal pin; inject packaging material into the injection mold to form a support for the metal sheet and wrap it The package of the metal pin and the sensing element is com...

Abstract

The invention provides a method for manufacturing a medical NTC temperature sensor structure. The method comprises the following steps that stamping is carried out to form metal sheet bodies, metal pins are formed on the formed metal sheet bodies, the two metal sheet bodies are symmetrically arranged in an injection mold, a set distance is reserved between the two metal pins, a sensing element isprovided, a packaging material is injected into the injection mold so as to form packaging pieces for supporting the metal sheet bodies and wrapping the metal pins and the sensing element, so that manufacturing of the sensor structure is completed. The method is simple in step and convenient to operate, and can greatly improve the manufacturing efficiency and the quality of the manufactured product.

Description

technical field [0001] The invention belongs to the technical field of sensors, in particular to a method for manufacturing a medical NTC temperature sensor structure. Background technique [0002] A sensor is a monitoring device that can feel the measured information, and can convert the sensed information into electrical signals or other required signals according to a certain rule, and is fully capable of disseminating, processing, storing, and displaying detailed information. , recording and control requirements. [0003] Sensors can be used in various electronic devices. For example, the battery on an electric vehicle will be equipped with a temperature sensor to monitor the temperature of the battery. The sensor can provide monitoring functions for the device connected to it. The connection between the sensor and the device is generally carried out using wires. Electrical signal connection, the wire uses welding, riveting, etc. to connect the sensor to the electrical ...
