Abstract

Abstract A temperature sensor for measuring the temperature of a part of an automobile, which sensor comprises in combination a clip and an electric heat-sensitive device, such as preferably a thermistor. The clip, which attaches the sensor to the automobile part, includes a first and a second jaw. These jaws are movable between a first and a second position. In the first position, the jaws are remote from each other, whereas in the second position they are positioned close to each other. In the first jaw, there is provided a recess adjacent to the second jaw. A heat-sensitive device is retained within this recess by a heat-conductive material. The automobile part, the temperature of which is to be determined, is enclosed between the jaws when the clip is in its second position.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 246 words
In an automotive testing device having an easily removable temperature sensor for selectively measuring the temperature of various parts of an automobile, comprising: (a) a clip for attachment to a selective one of said automobile parts, said clip having a first and a second curved jaw to more accurately measure the temperature, said jaws being movable between a first position, in which the jaws are positioned remote from each other, and a second position, in which the jaws are positioned close to each other, thereby enclosing said automobile part; (b) an extended recess extending along said first jaw and facing said second jaw; (c) a thermistor having electrical leads, said thermistor being retained within said recess by a heat-conductive material and said electrical leads being arranged in said recess; (d) first and second handles connected to the first and second jaw, respectively, wherein said first handle has a longitudinal axis and an opening formed along said axis for leading at least one electrical connecting lead therethrough; and (e) an electric cable having at least one electrical connecting lead, wherein at least one of said leads from said thermistor is electrically connected to a connecting point being arranged within said recess, and wherein said connecting lead of the cable is conducted through said opening in said first handle and along said first jaw and is electically connected to said connection point, whereby the electric cable is adapted to be detachably connected to a remote temperature indicating device.
Claim 2
Dependent Claim 246 words
In an automotive testing device having an easily removable temperature sensor for selectively measuring the temperature of various parts of an automobile, comprising: (a) a clip for attachment to a selective one of said automobile parts, said clip having a first and a second curved jaw to more accurately measure the temperature, said jaws being movable between a first position, in which the jaws are positioned remote from each other, and a second position, in which the jaws are positioned close to each other, thereby enclosing said automobile part; (b) an extended recess extending along said first jaw and facing said second jaw; (c) a thermistor having electrical leads, said thermistor being retained within said recess by a heat-conductive material and said electrical leads being arranged in said recess; (d) first and second handles connected to the first and second jaw, respectively, wherein said first handle has a longitudinal axis and an opening formed along said axis for leading at least one electrical connecting lead therethrough; and (e) an electric cable having at least one electrical connecting lead, wherein at least one of said leads from said thermistor is electrically connected to a connecting point being arranged within said recess, and wherein said connecting lead of the cable is conducted through said opening in said first handle and along said first jaw and is electically connected to said connection point, whereby the electric cable is adapted to be detachably connected to a remote temperature indicating device.
Claim 3
Dependent Claim 20 words
The temperature sensor according to claim 1, including a heat-shrink tubing, wherein said connection point is covered with said tubing.
Claim 4
Dependent Claim 22 words
The temperature sensor according to claim 1, wherein said jaws are covered with a heat insulating material, thereby leaving open said recess.
