TEMPERATURE SENSOR AND MANUFACTURING METHOD THEREFOR
First Claim
1. A temperature sensor comprising:
- a detector including;
a temperature sensing element disposed at a first end part;
a terminal disposed at a second end part; and
a lead wire coupling the temperature sensing element to the terminals;
a first mold-resin body covering the temperature sensing element, a portion of the terminal, and the lead wire; and
a second mold-resin body covering an another portion of the terminal and the first mold-resin body, the another portion of the terminal being exposed from the first mold-resin body,wherein a surface on which a gate mark of the second mold-resin body is formed faces a side of the first end part.

Abstract
A temperature sensor includes a detector and a first mold-resin body. The detector includes: a temperature sensing element which is disposed at a first end part of the detector, a terminal which is disposed at a second end part of the detector, and a lead wire for coupling the temperature sensing element to the terminal. The first mold-resin body covers the temperature sensing element, a portion the terminal, and the lead wire. The temperature sensor further includes a second mold-resin body which covers an another portion of the terminal and the first mold-resin body; the another portion of the terminal is exposed from the first mold-resin body. Then, a gate mark is formed on a surface of the second mold-resin body; the surface faces a side of the first end part.

5. A method of manufacturing a temperature sensor, the method comprising:
-
a first step of coupling a temperature sensing element to a terminal with a lead wire to form a detector; a second step of forming a first mold-resin body to cover the temperature sensing element, a portion of the terminal, and the lead wire, a third step of forming a second mold-resin body to cover the first mold-resin body and an another portion of the terminal, the another portion of the terminal being exposed from the first mold-resin body; and wherein, in the third step, a mold resin is charged into a molding die along a first direction from a first end part where the temperature sensing element is disposed toward a second end part where a coupler part is disposed.
