本考案は、温度測定用小型サーミスタの改良に
関するものである。[Detailed Description of the Invention] The present invention relates to an improvement of a small thermistor for temperature measurement.
現在、温度測定用のサーミスタには、ビード

型等種々の型式のものがあるが、応答速度が大で
かつ局部的な測温が可能であるところから小型サ
ーミスタ、特にビード型のものが好まれている。
しかし、ビード型サーミスタには性能の均一性が
不足するという問題点があつた。 Currently, there are various types of thermistors for temperature measurement such as bead type, disk type, washer type, flake type, and thick film type, but these have a fast response speed and can measure local temperature. For this reason, small thermistors, especially bead-type ones, are preferred.
However, bead-type thermistors have had the problem of lacking uniformity in performance.

御しようとしてもある程度のばらつきが生ずるこ
とは避けられないものであった。 When manufacturing bead type thermistors,
Normally, two conductive wires are placed close to each other, a certain amount of paste containing resistor material is placed on top of the wires at regular intervals, and after this is fired, each element is separated, and as needed. A method is used in which a small thermistor is completed by sealing the resistor bead portion with a glass sealing material. Therefore,
No matter how precisely the amount of compounded paste material, the shape of the bead, the firing conditions, etc. for forming the resistor bead are controlled, some degree of variation is unavoidable.

ーミスタと同様に使用できるものであるが、性能
上のばらつきが小さく、品質の均一性を格段に改
良するものである。 The small thermistor of the present invention can be used in the same way as a conventional bead-type thermistor, but it has less variation in performance and significantly improves the uniformity of quality.
本考案の小型サーミスタは、以下のようにして
作られるが、これを図に基いて説明する。 The small thermistor of the present invention is manufactured as follows, which will be explained based on the drawings.
先づ抵抗体の材料を配合混練して可塑性とした

取付ける側の線の長さは、抵抗体チツプの厚さ程
度であつて差支えない。 First, the materials for the resistor are mixed and kneaded to make them plastic, and then extruded into rod-shaped bodies as shown in FIG. 1, fired and then cut to produce resistor chips as shown in FIG. 2. This resistor chip 1 is shaped like a small plate, and vertical notches 2 are provided on the left and right sides of the resistor chip 1. On the other hand, two composite wires 3 fixed with a glass sealing body 4 are prepared at approximately the same distance as the distance between the notches 2 and 2', but the length of the wire on the side where the resistor chip is attached is , it may be about the same thickness as the resistor chip.
次いで抵抗体チツプ１をジユメツト線３の間で

る。 Next, the resistor chip 1 is placed on the glass sealing body 4 between the composite wires 3, and the tips of the composite wires are positioned in the notches 2 and 2' of the resistor chip 1, respectively. , 2' are filled with paste-like brazing material 5, such as silver solder, and heated and melted to fix the resistor chip. The thermistor body thus formed is covered with a glass sealing material 6 and further heated to melt it so that it becomes integrated with the glass sealing material 4 to which the composite wire was previously fixed.
The thermistor body is sealed to complete a small thermistor.

ガラス封止材によつて密封して構成されている。 The small thermistor thus obtained consists of a small plate-shaped resistor chip having vertical notches on both left and right sides, and two conductive wires whose tips are inserted into each of the notches. The thermistor body is fixed by the brazing material filled in the notch.
It is configured to be sealed with a glass sealant.

点を有している。 Since the small thermistor of the present invention is constructed in this way, the shape and dimensions of the resistor chip as well as the uniformity of the characteristics are much better than conventional products.
Chip inspection and thermistor assembly are also automated.
It has the advantage that it can be mass-produced with high accuracy and reliability more economically than conventional bead-type thermistors.
