DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings.
1 is a tube for cooling an air conditioner or the like, 2 is a mounting body formed of a thin metal plate of phosphor bronze, and its cross-sectional shape can be elastically expanded and inserted into the U-shaped tube 3 at the end of the tube 1. When one is formed on the flat lower edge 4 and the other is formed on the flat upper edge 5, the leading edge of the flat lower edge 4 is formed as an open-open bent edge 6, and the bent edge is formed. At the middle position in the longitudinal direction of the length 6, a retaining projection 7 (similar to a hook of a fishing hook) projecting inward is formed, and the tip of the flat upper edge 5 is bent outward to insert the thermistor terminal 8. The cylinder 9 is integrally formed (the retaining protrusion 7 is shown in a square shape, but may be formed in a semicircular arc).

Reference numeral 10 denotes a caulking portion for fixing the thermistor terminal 8 inserted into the insertion tube 9, and is formed with a cut 11.

The thermistor terminal 8 is formed by inserting a thermistor into a thin metal tube and hardening it with resin.

In FIG. 1, reference numeral 12 denotes an engagement hole formed in the flat lower edge 4, and reference numeral 13 denotes a connecting portion between the flat lower edge 4 and the flat upper edge 5. Although shown, it may be continuous.

FIGS. 6 and 7 show an insertion portion 14 corresponding to the insertion tube 9 formed on the inner surface of the flat upper edge 5, and the thermistor terminal 8 is mounted inside. The attachment of the thermistor terminal 8 is optional, and may be fixed with an adhesive. A cut 11 is also made in the insertion portion 14 to form the swaged portion 10.

[0011]

Next, the operation will be described. Since the present application has the above configuration, the thermistor terminal 8 is inserted into the insertion tube 9, the caulking portion 10 is caulked and fixed with a tool, and when the caulking portion 10 is attached to the U-shaped tube 3 at the end of the tube 1, the flatness is obtained. The space between the lower edge 4 and the flat upper edge 5 expands elastically and can be easily mounted. At this time, if the U-tube 3 is pushed into contact with the back surface of the connecting portion 13, the thermistor terminal 8 is in the correct position. Set, accurate temperature can be detected. Further, if the flat lower edge 4 is provided with the engaging holes 12 as shown in FIG. 3 or the continuous engaging holes 12, the U-shaped tube 3 engages with the engaging holes 12 so that the U-tube 3 can be mounted more securely. it can. 6 and 7 have the same operation.

Phosphor bronze in which the tip of the flat lower edge 4 is formed as an outwardly opened bent edge 6 and the tip of the flat upper edge 5 is bent outward to integrally form an insertion tube 9 for a thermistor terminal 8. Since it is a thermistor mounting device for a U-shaped tube of an air conditioner or the like composed of the mounting tool body 2 formed of a thin metal plate such as
When the U-shaped tube 3 at the end of the tube 1 is pushed in so as to be in close contact with the inner surface of the U-shaped mounting device main body 2, the thermistor terminal 8 can be easily mounted at a correct position, with good heat transfer and temperature control. Can do exactly. Further, the cross-sectional shape is a substantially U-shape which is elastically spread and inserted into the U-shaped tube 3 at the end of the tube 1, one of which is formed on the flat lower edge 4 and the other is formed on the flat upper edge 5, Phosphor bronze in which the flat lower edge 4 and the upper edge of the flat upper edge 5 are formed as open-open bent edges 6 and the insertion portion 14 of the thermistor terminal 8 is integrally formed inside the flat upper edge 5. Since the present invention is applied to a U-tube thermistor mounting device for an air conditioner or the like comprising the mounting tool main body 2 formed of a thin metal plate such as the above, the same effects as described above can be obtained. Further, since the device is a U-tube thermistor mounting device for an air conditioner or the like having a retaining projection 7 protruding inward at an intermediate position in the longitudinal direction of the bent edge 6 of the flat lower edge 4, the device is securely mounted. it can. In addition, the retaining projection 7 is formed in a U-shape of an air conditioner or the like formed in a semicircular arc.
Since the thermistor mounting device for a pipe is used, mounting is easy. Further, since the device is a thermistor mounting device for a U-shaped tube of an air conditioner or the like in which a cut 11 is formed in a part of the insertion tube 9 and the insertion portion 14 to form a caulked portion 10, the thermistor terminal 8 can be easily mounted. Can be Further, the flat lower edge 4, the flat upper edge 5, the connecting portion 13, and the insertion tube 9 are each formed with a sheet metal working of a thin metal plate such as phosphor bronze or the like. Therefore, it is easy to manufacture. The flat lower edge 4 is formed with a U-tube thermistor mounting device for an air conditioner or the like in which an engagement hole 12 of an arbitrary shape with which the U-tube 3 is engaged is formed. 3 is an engaging hole 1 of an arbitrary shape
