Patent ID: 6918696

Claim:
A temperature sensor comprising: a casing including a first part and a second part; a temperature detector for detecting temperature of fluid; and a pair of outside wires connecting to the temperature detector, wherein the casing further includes a mold portion and an insert portion, wherein the mold portion is disposed in the first part of the casing, wherein the insert portion is disposed in the second part of the casing, and includes a pair of holes for inserting the outside wires therein, wherein the temperature detector is disposed in the first part of the casing, and wherein each outside wire extends from the second part of the casing to an outside of the casing through one of the holes, wherein the mold portion is made of resin, wherein the first part has a distal end opposite to the insert portion, the distal end being opened, wherein the distal end of the first part is filled with the mold portion, wherein each outside wire includes a lead wire covered with an insulation tube so that the lead wire electrically connects to the temperature detector, wherein the detector is disposed in the mold portion so that the detector is fixed in the mold portion, wherein the temperature detector includes a detecting device and a pair of inside wires, wherein the detecting device connects to the outside wires through the inside wires, wherein the insert portion includes a separation portion, wherein the separation portion extends to the first part of the casing so that the separation portion separates between the inside wires, and wherein the inside wires are disposed in the mold portion so that the detector is fixed in the mold portion.
