[0024] The first embodiment, such as figure 1 As shown, a thin-film temperature sensor includes a metal support 12, an NTC thermistor 11 located at one end of the metal support 12, a rolled wire 14 located at the other end of the metal support 12, and a terminal hole located at the other end of the rolled wire 14. The seat 15 is used to cover the metal bracket 12 and the film 10 of the NTC thermistor 11 and the FFC or FPC flexible cable 13 used to wrap the rolled wire 14; one end of the FFC or FPC flexible cable 13 is connected to the film 10, and the other end is connected to the The terminal socket 15 is connected. Wherein, the NTC thermistor 11 is fixedly connected to one end of the metal bracket 12 by welding. The rolled wire 14 is fixedly connected to the other end of the metal bracket 12 by welding. The film 10 is made of polyimide, PET plastic, aramid, aramid, polyether ether ketone or silicone rubber. The thickness of the film 10 is 0-2 mm.

[0027] Second embodiment, such as figure 2 and image 3 As shown, a film-type temperature sensor includes a bare-chip NTC thermistor 11, a rolled wire 14 connected to the bare-chip NTC thermistor 11, a film 10, and an FFC or FPC flexible cable 13; the film 10 wraps the bare chip Type NTC thermistor 11 and one end of the rolled wire 14, and the FFC or FPC flexible flat cable 13 wraps the rolled wire 14.

[0028] The thin-film NTC temperature sensor is used in low temperature, and one end of the two rows of rolled wires 14 exposes the FFC flexible cable 3; use a jig to bend the exposed rolled wires 14 into a parallel shape, and then insert an NTC thermistor 11 of appropriate size into the rolled wires 14 bare parts. Although the single layer of the rolled wire 14 is very thin, after the rolled wire 14 is bent into a parallel state by a jig, two parallel rolled wires 14 are used to clamp the electrodes of the bare-chip NTC thermistor 11 so that it is not easy to fall off, and ...

Abstract

The invention discloses a thin film type temperature sensor. The thin film type temperature sensor comprises a metal support, an NTC thermistor arranged at one end of the metal support, calendaring wires arranged at the other end of the metal support, a terminal hole base arranged at the other ends of the calendaring wires, a thin film used for covering the metal support and the NTC thermistor, and FFC or FPC flexible flat cables used for wrapping the calendaring wires. One ends of the FFC or FPC flexible flat cables are connected with the thin film, and the other ends of the FFC or FPC flexible flat cables are connected with the terminal hole base. The thin film type temperature sensor has the advantages that by thin film packaging, the thin film type temperature sensor is good in insulation effect, good in stability, high in reliability, high in resistance value precision and safe to use; meanwhile, the length of the thin film type temperature sensor can be increased at will according to the needs of customers.

Description

technical field [0001] The invention relates to the technical field of temperature sensors, in particular to a thin-film temperature sensor. Background technique [0002] At present, the thin-film temperature sensor on the market mainly encapsulates the thermistor in a metal bracket to measure the external temperature. However, due to the limitation of the metal bracket process, the metal bracket cannot be made very long, so it is difficult to meet the needs of customers. , At the same time, the current thin film temperature sensor is not suitable for very humid environment. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies of the prior art and provide a thin-film temperature sensor. [0004] A kind of technical scheme of the present invention: [0005] A film-type temperature sensor, comprising: NTC thermistor, terminal hole seat, rolled wire connecting NTC thermistor and terminal hole seat, film and FFC or FPC flexible...
