Abstract

PURPOSE:To simply attain temporal connection and connection release of waveguides by containing a waveguide main body and a flange to a corresponding container respectively so as to provide a clipping pressure to the flange. CONSTITUTION:A middle part is a spring plate part 1a as a clipping pressure provision part and an opening 1c to accommodate a waveguide is formed to an edge center of a flat part 1b of a clip 1 whose both ends clip end press a flange. Then a flange 2a is in slight contact with a waveguide main body 2b, a lever member 1d separates a flat part 1b to move a clip 1 so as to allow the waveguide main body 2b to be accommodated in the opening 1c and an external force having been given to the lever member 1d is excluded. Thus, the flat plates 1b clip the flanges 2a while the relative position of the flanges is restricted by the opening 1c to attain the connection of the waveguides. Conversely when the lever member 1d part the flat plates 1b, the clipping of the flanges 2a is released. Thus, the connection and its release of the waveguides are facilitated in an experiment.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a waveguide clamper, and more specifically, to a clamper for connecting waveguides temporarily rather than permanently. The present invention relates to a waveguide clamping clamper used.

<Prior art and problems to be solved by the invention> Conventionally, flanges should be screwed together when connecting waveguides used as propagation paths for electromagnetic waves in the frequency range from microwaves to millimeter waves. is specified in the standard. However, instead of permanently connecting the waveguides, it is recommended to use screws even when conducting experiments, etc., since connecting and disconnecting the waveguides becomes quite complicated. The problem is that the work for extracting the screws becomes extremely complicated, which does not directly contribute to the experiment, and the time required for Sunsaku East becomes significantly longer.In particular, as the operating frequency increases, the flange also becomes smaller. This makes it difficult to screw in and remove the screws, making the above problem even more pronounced.

Various waveguide clamping clampers have been proposed in consideration of such problems (Japanese Patent Laid-Open No. 83-84401,
Utility Model Application No. 82-81501, Utility Model Application No. 81-1288
(Refer to Publication No. 03), all of these have guide pins that correspond to the flanges, and are applied when permanently connecting waveguides, so it is difficult to use them at the experimental stage when the flange shape etc. are not determined. If this method is to be applied, there is a problem in that many types of waveguide fastening clampers must be prepared in advance to correspond to the waveguides to be tested.

<Object of the invention> This invention was made in view of the above problems,
It is an object of the present invention to provide a new waveguide clamping clamper that can be easily applied at an experimental stage where the flange shape is not determined.

Means for Solving the Problems> In order to achieve the above object, the waveguide fastening clamper of the present invention includes a flange accommodating portion for accommodating a pair of waveguide flanges, and a flange accommodating portion for accommodating a pair of waveguide flanges. It has a waveguide accommodating section that accommodates the end portion, and a squeezing force applying section that applies a squeezing force to the pair of waveguide flanges accommodated in the flange accommodating section.

However, it is preferable that the flange accommodating part is a pair of flat plates, the clamping force applying part is a spring plate integrally formed with the flat plate, and the waveguide accommodating part is an opening formed at a predetermined position of the flat plate.

Alternatively, the flange accommodating part and the waveguide accommodating part may be grooves formed in a predetermined position of the clamper body so as to be perpendicular to each other, and the clamping force applying part may be a pressing member provided on the inner surface of the groove. . In this case, it is preferable that the clamper body is supported by a height-adjustable support member.

Further, the flange accommodating portion is a pair of frames that have a tapered through hole and can be moved toward and away from each other, the waveguide accommodating portion is a space between the frames in a close state, and the clamping force applying portion is a pair of frames that can be moved toward and away from each other. It may be a pressing member that presses the flange toward the narrow portion of the tapered through hole.

With the waveguide fastening clamper having the above configuration, a pair of waveguide flanges can be accommodated in the 7-lange accommodating section, and the ends of the pair of waveguides can be accommodated in the waveguide accommodating section. If a clamping force is applied by the clamping force applying unit to the pair of waveguide flanges housed in the flange housing unit, the flanges can be brought into close contact with each other, and the waveguides can be connected to each other.

When the flange accommodating portion is a pair of flat plates, the squeezing force applying portion is a spring plate integrally formed with the flat plate, and the waveguide accommodating portion is an opening formed at a predetermined position of the flat plate,
It is only necessary to separate the flat plates from each other against the spring plate, and in this state accommodate the end of the waveguide in the opening, as well as accommodate the flange between the flat plates. After that, special clamping pressure is applied. The flanges are clamped together by the elasticity of the spring plate, and the waveguides can be connected to each other without any work.

In addition, when the flange accommodating part and the waveguide accommodating part are grooves formed at predetermined positions of the clamper main body so as to be orthogonal to each other, and the clamping force applying part is a pressing member provided on the inner surface of the groove, It is only necessary to accommodate the end portions of the waveguides and the flanges in the grooves, and the flanges can be pressed together by the pressing member, so that the waveguides can be connected to each other without performing any special pressing operation. In this case, if the clamper main body is supported by a height-adjustable support member, the waveguide connection portion can be supported at a height suitable for the experiment, and the influence of gravity can be eliminated.

Further, the flange accommodating portion is a pair of frames that have a tapered through hole and can be moved toward and away from each other, the waveguide accommodating portion is a space between the frames in a close state, and the clamping force applying portion is a pair of frames that can be moved toward and away from each other. In the case of a pressing member that presses the flange toward the narrow part of the tapered through hole, positioning in the pressing direction can be automatically achieved as a result of pressing by the pressing member without increasing the positioning accuracy of the flange. .

<Example> Hereinafter, embodiments will be described in detail with reference to the accompanying drawings showing examples.

FIG. 1 is a perspective view showing an embodiment of the waveguide fastening clamper of the present invention, in which the central part is a spring plate part (1a) as a clamping force applying part, and both ends are for clamping the flange. An opening (IC) for accommodating a waveguide is formed at the center of the edge of the flat plate part (1b) of the clip (1), which is a flat plate part (1b). Board part (
This is a lever member for rotating the flat plate part (1b) against the elasticity of the part 1a).

When connecting the waveguides, first, while the flanges (2a) are in light contact with each other, the flat plate part (1b) is separated using the lever member (ld), as shown in FIG. 2(A). After moving the clip (1) so that the waveguide body (2b) is accommodated in the opening (IC), it is only necessary to remove the external force applied to the lever member (ld), and the opening (1c) The flanges (2a) are pinched together by the flat plate part (1b) while their relative positions are regulated (see FIG. 2(B)),
Connections between waveguides can be achieved.

Conversely, when disconnecting waveguides, use a lever member (l
d), it is sufficient to separate the flat plate portions (tb) from each other, and the pinching pressure between the flanges (2a) can be released. Of course, if the situation permits, the waveguide can be simply pulled out in the direction of extraction (direction of extraction from the opening (Lc)) without operating the lever member (ld).
It may be forcibly moved.

As is clear from the above description, the waveguide clamping clamper of this embodiment can be used with guides having flanges of various shapes as long as the waveguide body (2b) can be accommodated in the opening (IC). It can be applied to connecting waveguides.As a result, even during experiments where waveguides are frequently replaced, the work required to connect and disconnect waveguides can be greatly simplified, significantly improving the workability of experiments. can be increased.

<Embodiment 2> Fig. 3 is a perspective view showing another embodiment of the waveguide fastening clamper of the present invention, in which grooves (3a) and (3b) perpendicular to each other are provided at predetermined positions of the clamper body (3). It is formed. The groove (3a) is for accommodating the flange (2a), and a ball bearing (3c) for supporting the flange (2a) under pressure is provided on the inner surface (see also Fig. 4). . The groove (8b) is for accommodating the waveguide body (2b), and both ends thereof face the outside.

When connecting waveguides, the waveguides may be accommodated in the grooves (3a) (3b) with the flanges (2a) in slight contact with each other, and the ball bearings (3c) will connect the waveguide body (2b). ) while maintaining the position of the flange (2).
a) The same clamping pressure as above can be achieved. Conversely, the connection can be easily broken by forcibly removing the waveguide.

Also in the case of this embodiment, connection of various waveguides having flanges (2a) shaped to accommodate the entire waveguide (3a) can be easily achieved.

In addition, although the embodiment in which ball bearings (3c) are provided on the inner surfaces of the grooves (3a) and (3b) has been described above,
Instead of the ball bearing, a leaf spring curved into an arc may be provided.

FIG. 5 is a perspective view showing a modification example, and shows the clamper body (3
) is formed with a hole (3d) that engages with the stand (4) serving as a supporting member on the bottom surface and the side surface directly facing the groove (3a), and any hole (3d> is connected to the stand (4).
is engaged with. In addition, the stand (4) has a base (4a
) is supported such that the engaging member (4b) can move up and down, and a screw (4c) is provided that can prevent the engaging member (4b) from going up and down.

Therefore, in the case of this modification, the retaining member (4b)
By raising and lowering the waveguide to a desired height and preventing the raising and lowering with the screw (4c), it is possible to reliably prevent the influence of gravity at the connection portion of the waveguide. Further, since the hole (3d) in which the engaging member (4b) engages can be changed depending on the orientation of the waveguide, a good temporary connection can be achieved regardless of the orientation of the waveguide.

(Embodiment 3) FIG. 6 is a perspective view showing still another embodiment of the waveguide fastening clamper of the present invention, in which a pair of inverted trapezoidal frames (5a ) and frame (5a)
The support body (5b) rotatably supports the upper end edge of the support body (5b), and the suppressing body (5c) vertically penetrates the support body (5b>).

The support body (5b) has an upper edge length ε of the frame body (5a) which is approximately the same length and a width which is approximately the same as that of the waveguide body, and the frame body (5a ) is integrally formed with a flange (5d) that restricts rotation. A screw hole is formed vertically through the center of the support (5b), and a screw hole ε is formed in the center of the presser (5c) that vertically penetrates the support (5b). ing. Further, a frame body (5

In the case of this embodiment, the frame body (5a) is rotated upward via the hinge mechanism (5e) (see the two-dot chain line in FIG. 7(A)), and the lower part of the support body (5b) is widened. Releasing allows reception of the lightly abutted flange (2a). In this state, the flange (2a) and the pressing body (5
C> is brought into contact with the pressing plate (5g) and the frame (5a) is rotated downward. This causes the end edge of the flange (2a) to be accommodated in the frame (5a) (Fig. 7(A) (see solid line). After that, all you have to do is operate the knob (5r), and the press plate (5g) will move the flange (2a) downward, so that the lower edge of the flange (2a) will eventually touch the frame (5a).
Since the waveguides are pressed against the tapered surface of the flange (2a) and pressure force is applied to the flange (2a), the waveguides can be connected to each other (see FIG. 7(B)).

Conversely, to disconnect the waveguides, simply perform the opposite operation.

(Embodiment f!T44> FIG. 8 is a perspective view showing still another embodiment of the pre-waveguide fastening clamper of the present invention, which is curved into a predetermined shape so as to press the predetermined position of the 7 langes (2a).

The linear pressing members (8a) can be elastically deformed to some extent in the direction of separating from each other with respect to the connecting portion.Also, the space (6d) between the linear pressing members (8a)
is the waveguide main body accommodation space.

Therefore, in the case of this embodiment, the linear pressing member (6
Flange (2a) with a) elastically deformed to some extent
(see Fig. 9(A)). Next, the engagement frame (8b) is rotated so as to engage the locking member (Be) ε, and in this state, the locking member (Be) is Engagement frame (8b
), the linear pressing member (6a) can be brought into strong pressure contact with the flange (2a) (see FIG. 9(B)). As a result, the flanges (2a) can be strongly pressed against each other, and the waveguides can be connected to each other.

To disconnect the waveguides, simply perform the reverse operation.

However, in this embodiment, it is also possible to engage the linear pressing member (6a), the engagement frame (6b), and the locking member (Be) so that they can not only rotate but also slide. In this case, there is no need to elastically deform the linear pressing member (8a), and the service life can be extended.

The present invention is not limited to the above-mentioned embodiments, and can be applied to waveguides having shapes other than rectangular waveguides, such as circular waveguides, elliptical waveguides, etc. Various design changes can be made without changing the gist of the invention.

<Effects of the Invention> As described above, in the first invention, it is only necessary to accommodate the waveguide main body and the flange in their corresponding housing parts, and apply a clamping force to the flange using the clamping force applying part in this state. Therefore, there is no need for screwing or the like, and a unique effect is achieved in that temporary connection and disconnection between waveguides can be easily achieved.
