[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waveguide connector for connecting flanges at ends of two waveguides.

[0002]

2. Description of the Related Art Conventionally, in order to connect waveguides, flanges provided at ends of both waveguides are fastened with bolts. To connect both flanges, for example,
A clip 41 for connecting a waveguide described in Japanese Patent No. 29201 is known. As shown in FIG. 6, to connect both flanges using the clip 41, two of the four positioning holes of both flanges connected to each other are connected.
The gripping is performed by gripping one side of the flange where the two positioning holes are located, and two sets of clips are used to grip and connect each side of both flanges.

[0003] In detail, each clip 41
Are two arms 45 whose center portions are swingably connected by a fixing pin 43, and a fixing pin 4 on the axis of the fixing pin 43.
A bolt 47 is provided perpendicularly to the bolt 3, and a spring 49 is provided at a lower end of the bolt 47 to bias the two arms 45 in a closing direction. And the bolt 4
7, a washer 51 and a conical spacer 53 are provided. A knob 55 is provided at an upper end of the bolt 47 so as to move the spacer 53 up and down on the axis of the bolt 47. This is a structure in which two guide pins 57 which are inserted into the holes of the flange of the pipe to determine the joining position are protruded. Then, by expanding the arm 45 and turning the knob 55 to push the spacer 53, the force sandwiching the arms 45 from the spacer 53 is transmitted from the spacer 53,
One side of both flanges can be gripped and connected.

[0004]

However, the conventional waveguide connector has the following problems. In the conventional connecting device, there is a problem that the connecting device itself becomes large-sized due to its complicated structure, and is difficult to be applied to a narrow space inside the device. In addition, there is a problem that the connector itself cannot be applied to a high-frequency waveguide having a small flange because the connector itself becomes large.

An object of the present invention is to provide a waveguide connector which has a simple structure and can be miniaturized, and can be applied to a flange of a high-frequency waveguide.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides two waveguides by abutting the abutting surfaces of flanges at the ends of a waveguide and holding the rear portions of both flanges. A waveguide connecting device for connecting tubes, wherein a first arm and a second arm each pivotally move in a direction in which distal ends are separated from each other and approach each other with a connection point on a base end side as a fulcrum; A contact plate which is swingably attached to the distal ends of the first arm and the second arm, respectively, and which comes into contact with the rear surfaces of the two flanges; and which protrudes from the distal end face of one of the contact plates. A positioning pin inserted from a positioning hole of a flange of one waveguide of the two waveguides to a positioning hole of a flange of the other waveguide, wherein the first arm and the second arm are provided. Is the extension from the connection point to the tip The bent portion is formed in an intermediate portion of the direction,
The connection point extends from the connection point to the bending portion in a direction away from each other, and the bending portion extends from the connection point to the distal end so as to approach each other. Has a proximal end extending in the opposite direction,
A rotating operation is performed over the base end of the first arm and a point between the connection point of the second arm and the bent portion, so that the distal ends of the first arm and the second arm are separated from each other and approached. An operating bolt for swinging in the direction is provided.

In the present invention, the distance between the contact plates of the two arms is maximized, and the flanges of the two waveguides are brought into almost complete contact with each other, and are protruded from one of the contact plates. A positioning pin is inserted into each of the positioning holes, thereby positioning both flanges.
After that, when the operating bolt is rotated, the tip of the other arm swings toward the tip of one arm, and the contact plate attached to the tip of this arm moves from the back of the other flange to the one flange. The two flanges are clamped from outside by both contact plates and tightened, and the two flanges are securely connected.

Therefore, the positioning and fixing of the two flanges can be easily performed, and the simple structure allows the downsizing and the use in a narrow work space. It can be applied to a small flange of a wave tube. Furthermore, since it can be applied without requiring a special structure for the flange of the waveguide, it is possible to use it as it is for a standard waveguide.

As shown in FIGS. 2 and 3, the waveguide connector 7 is located on the back surface 3B of the flange 3 opposite to the abutment surface 3A, and is provided with two of the four positioning holes 5. It is used to grip the portion where the hole 5 exists, and two waveguide connectors 7 are used one by one on the left and right sides of the waveguide 1. As shown in FIG. 1, the waveguide connector 7 includes a holding portion 9 for sandwiching the back surface 3B of the flange 3 connected to each other from both outsides.

The holding portion 9 is composed of a pair of arms 11, each of which has a predetermined length.

Supported, both arms 11 each have a bent portion 11A in the middle,
Is formed so as to gradually move away from the base end toward the bent portion 11A and gradually approach from the bent portion 11A toward the distal end. Further, the front ends of both arms 11 are formed on the front end surfaces of the flanges 3 via a swing pin 15 so as to be in contact with the portions where the two positioning holes 5 of the back surface 3B of the flange 3 are connected. The contact plates 17 are respectively mounted. Out of the respective contact plates 17, two positioning pins 19 are provided at the tip end surface of one of the contact plates 17 so as to be inserted into two upper and lower positioning holes 5 provided in the flange 3. These positioning pins 19 are formed to have a length that allows them to be inserted into the positioning holes 5 of the other flange 3 to be connected.

The base end of the one arm 11 is slightly bent toward the other arm 11 so as to extend therefrom. An operation bolt 21 is provided at the bifurcated base end 11C of the one arm 11 with a female screw member. 23. That is, a right-facing male screw is formed on the outer periphery of the operation bolt 21, a female screw to be screwed to the operation bolt 21 is formed in the female screw member 23, and the female screw member 23 screwed to the operation bolt 21 is interposed through the pin 25.

When the operating bolt 21 is rotated clockwise, the contact plates 1 of both arms 11 are rotated.
When the operating bolts 21 are rotated to the left (counterclockwise), the contact plates 17 of the two arms 11 are separated from each other and spread.

Next, the case where the waveguide 1 is connected by the waveguide connector 7 having the above structure will be described with reference to the drawings.
First, the operation bolt 21 of the waveguide connector 7 is rotated to the left so that the distance between the contact plates 17 of both arms 11 is maximized as shown in FIG. Next, the flanges 3 of the waveguides 1 to be connected to each other are substantially aligned, their contact surfaces 3A are brought into contact with each other, and the positioning pins 19 protruding from one contact plate 17 are connected to the other flange 3. Are inserted into the positioning holes 5, thereby positioning the two flanges 3.

An insertion hole 37 is formed in one contact plate 17 to which the positioning bolt 35 is attached, and one flange is formed. 3, a female screw is formed in the positioning hole 5 so that one contact plate 17 can be detachably fixed to one flange 3 by a positioning bolt 35. As a result, both the flanges 3 are positioned by being inserted into the positioning holes 5 of the flanges 3 by the positioning bolts 35, and the one contact plate 17 of the waveguide connector 7 is screwed to the one flange 3. The two waveguides 1 can be fixed, and even when the two waveguides 1 are removed, the waveguide connector 7 can be kept connected to the flange 3 without being separated from the one flange 3, and the next operation can be performed. Simplification can be achieved.
