ている。[Detailed Description of the Invention] The present invention relates to a support for a thermocouple element, and a means for fixing lead wires (brazing, electric welding, etc.)
The aim is to improve mass productivity of the thermocouple element itself, reduce costs, and make wiring to equipment easier.
従来の熱電対素子は第１図に示す如く、本体２
と感熱部１とをろう付し、本体２とリード線３も
ろう付又は電気溶接などで固定されている。 The conventional thermocouple element has a main body 2 as shown in Fig. 1.
and the heat sensitive part 1 are brazed, and the main body 2 and the lead wire 3 are also fixed by brazing or electric welding.

イ，ロはろう付部である。 The body 2 and the heat sensitive part 1 are short, approximately 70 to 80 mm after brazing, and the body 2 is made of copper pipe or brass, and the heat sensitive part 1 is also made of pressed metal, making it easy to handle, and the brazing process can be automated. It is possible. but,
The lead wire 3 is made of copper wire and is wire-like, making it difficult to handle.Since the main body 2 and the lead wire 3 have a circular diameter, they are fixed at point contact, which makes it difficult to braze, and because they are handmade, the cost is high. is the current situation. Also, even after the finished product, the lead wire 3 itself is made of copper wire due to the length of the lead wire, so it is wire-like and has less flexibility when wiring devices, etc., and also takes up space. It is also required separately, resulting in high costs. This makes it even more difficult to handle when there is no installation space when actually wiring the equipment. In Figure 1, 1 is the heat sensitive part, 2 is the main body,
3 and 4 are lead wires, 5 is the enamel of the lead wire 4, and 6 is an insulating tube between the lead wire 4 and the main body 2;
A and B are the brazed parts.

１の被覆部である。 In Figures 2, 3, and 4, 1 is a heat sensitive part, and two different metals A and B (chromel A and constantan B) are welded at the tip to form a contact point 1a, and a contact point 1a is further formed with constantan B, which will be described later. The contact point 1b is formed by welding the contact point 1b to the lead wire 4, and the two contact points are maintained at different temperatures to create a temperature difference and generate a thermoelectromotive force. 2 is a main body, 4 is a lead wire, 5 is an enamel portion coated on the lead wire, 6 is an insulation coating tube between the main body 2 and the lead wire 4, 7 is a recess provided in the main body 2, and 8 is a recess provided in the main body 2. 9 is a connecting terminal, which has a cylindrical part 9b with a groove 9a formed in the longitudinal direction, and a concave part of the main body 2 in the middle. A convex portion 10 that engages with 7 is formed. 11 is a lead wire, 12 is a lead wire caulking part of a connecting terminal,
13 is a support part for the lead wire 11, 14 is a lead wire 1
This is the covering portion of No. 1.

接続端子９を介して本体２に接続される。 In the above embodiment, when the connecting terminal 9 with the lead wire 11 fixed by the lead wire caulking part 12 is inserted into the tapered part 8 of the main body 2, the cylindrical part 9b of the connecting terminal 9 expands due to the split groove 9a. While moving, the convex portion 10 engages with the concave portion 7 of the main body 2 by the elastic force of the connecting terminal 9. Therefore, the lead wire 11 is connected to the main body 2 via the connection terminal 9.

る。 As described above, in the present invention, a lead wire is connected to the tapered part of the main body having a heat-sensitive part at the tip, and a cylindrical connecting terminal having a groove in the longitudinal direction is connected by fitting the concave and convex parts. It has the following effects.
(1) ろう付加工工程が省けるので量産性が向上し
コストダウンとなる。(1) Since the brazing process can be omitted, mass productivity is improved and costs are reduced.
(2) 配線後も抜き差しこみが可能となりサービス
上も有利である。(2) Even after wiring, it can be inserted and removed, which is advantageous in terms of service.
(3) リード線は従来の銅線の1.6φでなくて市販
のジーゲル線等でよく器具内での配線に自由度
が生れ、スペースのない場所でも、リード線の
接触等を考慮しなくとも良いことは機器の安全
性も高めることになる。(3) Instead of the conventional 1.6φ copper wire, the lead wire can be a commercially available Siegel wire, etc., giving you more flexibility in wiring inside the device, and even in places with limited space, you don't have to worry about lead wires contacting each other. A good thing is that it also increases the safety of the equipment.
(4) リード線部と本体部とに分けて生産、在庫で
きるので保管上も有利になる。(4) The lead wire section and the main body section can be produced and stocked separately, which is advantageous in terms of storage.
