Abstract

PURPOSE:To improve the assembling work and to increase greatly the packing density by attaching a circular band having an approximately V-shaped section to the taper part of a pair of waveguide flanges in an attachable/detachable way for connection of waveguides. CONSTITUTION:A pin 4 is pressed into a waveguide flange 1a for positioning of waveguide flanges 1a and 1b, and the flange 1b has a hole for attachment of the pin 4. A circular band 6 having an approximately V-shaped section is attached to the taper parts 5a and 5b at the outer circumferences of flanges 1a and 1b. The band 6 contains a ring 7, a screw rod 8 and a nut 9. Then waveguides 2a and 2b can be connected to each other by attaching the rod 8 tight to the nut 9. In such a way of connection, the use of plural bolts is eliminated to contribute to the improvement of working efficiency. In addition, the packing density is greatly increased since an attachment space of the band 6 is secured at the outer circumferences of the flanges 1a and 1b.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a waveguide connection method for a three-dimensional circuit incorporated in an electronic device.

As we all know, the three-dimensional circuits of electronic devices are made up of waveguides, micro parts, etc. , l; and each connection is made via a waveguide flange.

First, a conventional waveguide connection method will be described. In Figure 1, (1a) and (1b) are the waveguide 7 langes, (2a) and (2b) are the waveguides, and (3) are the pair of waveguide 7 langes (1a) and (1b). ) is the bolt that connects it. Further, (4) is a pin for positioning the waveguide flanges (1a), (1b)\, and is press-fitted into the waveguide 7 flange (1a).

By the way, such a conventional waveguide flange (1a),
In the connection work (1b), when assembling the three-dimensional circuit, it was difficult to reach between the three-dimensional circuits, and the bolts (3)
The reality is that tools such as G-tweezers are used to assemble the flange in places where it is difficult to insert the flange into the flange mounting hole.

However, this method is not only inefficient in assembly work, but also has a limitation in terms of mounting density, and there has been a strong desire for improvement in terms of increasing the density.

This invention has been made to solve the above-mentioned problems, and will be described in detail below with reference to embodiments shown in FIGS. 2 and 3.

FIG. 2 is a diagram showing a state in which a pair of waveguide flanges according to the present invention are connected, and FIG. 3 is an AA sectional view of the structure shown in FIG. 2.

In the figure, (Ia) and (1b) are tapered portions (sa) on the outer periphery.

(5b) A circular waveguide flange having a flange (4) is a pin for positioning the waveguide 7 flange (1a) and ('b), the waveguide flange (1a) K
The waveguide flange (1) is press-fitted, and the waveguide flange (1) is provided with a hole for engaging the pin (4).

The taper parts (sa) and (sb) above are removable.
A circular band with a shaped cross section is engaged. In addition.

This circular band (6) consists of a ring (7), a threaded rod (8)
) and a nut (9), and by screwing and tightening the threaded rod (8) into the nut (9), the waveguides (2a) and (2b) can be fully connected.

This invention has the configuration as described above.

Does not require multiple bolts for fastening as in the past,
Therefore, it is useful for improving work efficiency.

Furthermore, since it is only necessary to secure a space on the outer periphery of the waveguide flanges (1a) and (1b) in which the circular band (6) can be attached, it is possible to greatly increase the packaging density compared to the conventional method. can.
