Abstract

PURPOSE:To improve the workability of assembling by fastening a couple of waveguide flanges with a tightening member formed incorporatedly so that its profile and cross section are formed in U shape at room temperature. CONSTITUTION:The tightening member 5 is heated to a transformation temperature or over and deformed at the connection of waveguides 2a, 2b and after the member 5 is mounted from the end face of the couple of the waveguide flanges 1a, 1b, the temperature of the tightening member 5 is decreased to room temperature. Thus, since the tightening member 5 is restored to the shape as shown in the figure, the couple of the waveguide flanges 1a, 1b are tightened by the elastic force of the folded part.

Description

[Detailed Description of the Invention] This invention describes the well-known history of three-dimensional circuits that can be assembled into electronic devices.1 Three-dimensional circuits for electronic and electronic devices are intricately intricately composed of waveguides and microcomponents, and each connection is made using waveguides. This is done through a pipe flange.

First, a conventional waveguide connection method will be explained.

In Fig. 1, (Ia) and (ib) are waveguide flanges.

(2a) and (2b) are waveguides, and (3) is a bolt for connecting the two waveguide flanges. Further, (4) is a positioning pin press-fitted into the waveguide flange (2a).

By the way, such a conventional waveguide flange (1a),
(11)) When assembling the three-dimensional circuit, insert your hand between the three-dimensional circuits, insert the bolt (3) into the flange mounting hole, In the past, tools such as tweezers were used for assembly work.

However, this method suffers from poor assembly workability, and there is a natural limit to the mounting density, and improvements have been strongly desired from the perspective of further increasing the density.

This invention was made to improve the above-mentioned problems, and will be explained below with reference to the embodiments shown in FIGS. 2 to 4.

FIG. 2 shows the waveguide connection method according to the present invention.

FIG. 1 shows a state in which a pair of waveguide flanges are connected.

3 and 4 are detailed views of the fastening member which is a feature of the present invention.

In the figure, numeral 51 denotes a fastening member integrally formed of a shape memory alloy so that the outer shape of the outer shape and the cross-sectional shape of 9 form a U-shape as shown in FIG. 3 at room temperature.

In addition, FIG. 4 shows the transformation temperature (
The above fastening member (5
), all of the bent portions of the waveguides (2a) and (2b) are slightly open to the outside.
) At the time of connection, the fastening member (5) is heated above the transformation point temperature, deformed as shown in FIG. When the temperature of the fastening part (5) is lowered to room temperature, the fastening part tries to return to the shape shown in FIG. 3, so the bending is caused by the elastic force of the part. Wave tube flange (1a).

(1b) can be concluded.

This invention has the configuration as described above.

Because there is no need for bolts for fastening like in the past.

It is extremely easy to assemble and can greatly improve efficiency.

It is a good idea to secure a space on one side of the negative side of the flange in which the fastening part side can be mounted, so that the packaging density can be greatly increased compared to the conventional method.

In the embodiment, the size of the flange is the same as that of the conventional flange, but since there is no need to provide bolt mounting holes in the corners, it is possible to make the flange much smaller than the conventional flange.
