Temperature sensor

Abstract

The present invention provides a temperature sensor with a reduced number of parts. In a temperature sensor (10), an entire opening portion (14) of a holder (12) is covered by a cap portion (44A) of a sensor cover (44), so that water drops etc. are prevented from entering between the holder (12) and a filled resin portion (42). Further, wire breakage in a harness pair (34A, 34B) caused by excessive bending is restricted by a neck portion (44B) of the sensor cover (44). The cap portion (44A) and the neck portion (44B) are both part of the sensor cover (44) and are integrated together. In the temperature sensor (10) with such a sensor cover (44), the number of parts is less than that of a temperature sensor (50) where a cap and a lead-wire lead-out member are separate bodies.

AI Technical Summary

Benefits of technology

This patented technology makes it possible for an improved type of temperature sensing device that has fewer components than previous designs.

Problems solved by technology

Technological Problem addressed in this patented technology describes conventional temperatures detectors used in electronic devices due to their use of multiple parts including an inner case containing a heat sensitive material called PTC or resistance type temperature detector(s). These parts have been separately placed during production, making assembly processes complicated.
