The following is a detailed description of the implementation details of the waveguide interface structure 100 of the present embodiment, and the following is provided only for the sake of understanding and is not necessary for implementing the present embodiment.
In practical applications, the electrical connection 11 may include: the annular main body part 111 is connected with the fixing part 12, and the plurality of elastic sheets 112 are arranged on the annular main body part 111 at intervals, the annular main body part 111 is used for being attached to the end face of the first waveguide 10, the plurality of elastic sheets 112 are used for abutting against the end face of the second waveguide 20, the plurality of elastic sheets 112 extend along the direction far away from the annular main body part 111 and jointly enclose into the opening 30, the opening 30 is arranged opposite to the central through hole of the annular main body part 111 so as to facilitate the transmission of electromagnetic waves, the plurality of elastic sheets 112 are elastically pressed between the end face of the first waveguide 10 and the end face of the second waveguide 20 and electrically connect the first waveguide 10 and the second waveguide 20, large-area contact is converted into multi-point contact, the problem of poor contact of a large area is effectively avoided, and the processing precision and the assembling requirements of the elastic sheets 112 are reduced.
In order to meet the signal transmission requirement, the size of the opening 30 changes according to the size of the waveguide interconnection gap and the deformation of the elastic sheet 112, as long as the electrical property matching between the size of the opening 30 and the size of the waveguide is always ensured. The waveguide interface structure 100 may be suitable for application scenarios such as rectangular waveguide, circular waveguide, ridge waveguide, etc., the dome 112 scheme is a broadband design, and the working frequency range is consistent with the waveguide working frequency range. The central opening 30 is designed differently according to the waveguide type, for example, the opening 30 may be rectangular for a rectangular waveguide, and the opening 30 may be circular for a circular waveguide; for a ridge waveguide, the opening 30 may be ridge-shaped.
The material of the annular main body 111 may be a conductive material, such as a metal, and the material of the elastic piece 112 may be a conductive material having elasticity, such as a metal. Of course, the annular main body 111 and the spring 112 may be made of conductive material only on the surface and insulating material (e.g., plastic) on the inside, as long as the first waveguide 10 and the second waveguide 20 are electrically connected via the annular main body 111 and the spring 112.
In practical applications, the elastic sheet 112 may be formed by stamping or etching and then folding, and the cylindrical isolation portion 114 may be formed by bending a planar metal sheet into a cylindrical shape and then welding. In order to reduce the difficulty of processing, the elastic sheet 112 and the cylindrical spacer 114 may be processed separately and then welded together. Since the waveguide interface structure 100 of the present embodiment is low in material cost and easy to process, it can be mass-produced by a mold, and has a cost advantage compared to a conductive rubber ring.
In this embodiment, each elastic sheet 112 may include: the first extension portion 112a connected to the annular main body portion 111 and the second extension portion 112b bent and extended from the first extension portion 112a are used for abutting against an end surface of the second waveguide 20, and the second extension portion 112b is bent and extended from the first extension portion 112a, so that the joint between the first extension portion 112a and the second extension portion 112b is more easily elastically deformed, and gaps with different sizes between the first waveguide 10 and the second waveguide 20 can be better adapted.
The first extension portion 112a may be disposed at the inner edge 111a of the annular main body portion 111, or disposed at the outer edge 111b of the annular main body portion 111, or a part of the first extension portion 112a is disposed at the inner edge 111a of the annular main body portion 111, and another part of the first extension portion 112a is disposed at the outer edge 111b of the annular main body portion 111. Of course, the first extension portion 112a may not be disposed at the edge of the annular main body portion 111, but may be disposed between the inner edge 111a and the outer edge 111b, which is not limited herein.
For each elastic sheet 112, the second extending portion 112b and the first extending portion 112a may be arranged in an obtuse angle, an acute angle, or a right angle (that is, the included angle between the second extending portion 112b and the first extending portion 112a is an obtuse angle, an acute angle, or a right angle), and the joint of the second extending portion 112b and the first extending portion 112a is used for abutting against the end surface of the second waveguide 20, or the end of the second extending portion 112b far from the first extending portion 112a is used for abutting against the end surface of the second waveguide 20.
For all the elastic sheets 112, the same arrangement may be adopted, for example, each second extending portion 112b and the corresponding first extending portion 112a are arranged in an obtuse angle, an acute angle or a right angle; the elastic pieces 112 with different arrangement modes can also be combined, and the arrangement mode of each elastic piece 112 can be any one of the above, for example, one part of the second extending portions 112b and the corresponding first extending portions 112a are arranged in an obtuse angle, and the other part of the second extending portions 112b and the corresponding first extending portions 112a are arranged in an acute angle.
For ease of understanding, two examples are given below:
as shown in fig. 1, 2, and 3, the first extending portions 112a are disposed on the inner edge 111a of the annular main body portion 111, and the second extending portions 112b and the first extending portions 112a are disposed at an obtuse angle, a junction of the second extending portions 112b and the first extending portions 112a is used for abutting against an end surface of the first waveguide 10, and an end of the second extending portions 112b far from the first extending portions 112a is used for abutting against an end surface of the second waveguide 20.
As shown in fig. 4, 5, and 6, a part of the first extending portion 112a is disposed at the inner edge 111a of the annular main body portion 111, another part of the first extending portion 112a is disposed at the outer edge 111b of the annular main body portion 111, and the second extending portion 112b and the first extending portion 112a are disposed at an acute angle, the intersection of the second extending portion 112b and the first extending portion 112a is used for abutting against the end surface of the first waveguide 10, and one end of the second extending portion 112b away from the first extending portion 112a is used for abutting against the end surface of the second waveguide 20.
As shown in fig. 7, 8, and 9, the first extending portions 112a are disposed on the inner edge 111a of the annular main body portion 111, and a portion of the second extending portion 112b and the corresponding first extending portion 112a form an obtuse angle, and another portion of the second extending portion 112b and the corresponding first extending portion 112a form an acute angle, where a junction of the second extending portion 112b and the first extending portion 112a is used for abutting against an end surface of the first waveguide 10, and an end of the second extending portion 112b far from the first extending portion 112a is used for abutting against an end surface of the second waveguide 20.
To ensure reliable contact and electrical performance within the tolerance range, the finger width, finger spacing, finger length and shape of the spring plate 112 are designed by simulation. The finger width needs to consider the elasticity and deformation quantity of the material (the smaller the finger width is, the better the elasticity is), and the good contact is ensured all the time under the condition of different gap sizes; the distance between the fingers meets the cut-off waveguide theory and is reasonably designed according to the leakage-proof target; the finger length and shape determine tolerance absorption (ability to accommodate the size of the gap between waveguides) and electrical performance.
Specifically, if the waveguide interface structure 100 is suitable for a waveguide for transmitting electromagnetic waves with a first wavelength (the opening 30 is used for passing the electromagnetic waves with the first wavelength), that is, the first waveguide 10 and the second waveguide 20 are used for transmitting electromagnetic waves with the first wavelength, the finger width determines the length of the contact surface between the elastic sheet 112 and the waveguide, and in order to ensure reliable electrical contact, the widths w (i.e., the finger widths) of the elastic sheets 112 in the arrangement direction along the elastic sheets 112 may be less than 0.2 times the first wavelength; according to the leakage prevention objective, with the cut-off waveguide theory, the distances v (i.e., finger distances) between adjacent clips 112 in the arrangement direction along the clips 112 may each be less than 0.05 times the first wavelength; to ensure sufficient elasticity, the thickness of the spring plate 112 is generally less than 0.2 mm.
Alternatively, in practical applications, the fixing portion 12 may be provided with a mounting hole 13, and a screw is inserted into the mounting hole 13 and fixed on one end of the waveguide (i.e., the first waveguide 10), so as to implement the installation of the waveguide interface structure 100.
In the waveguide interface structure 100 provided in this embodiment, the gap absorption capacity may be 0 to 2 mm, that is, when the distance between the end surface of the first waveguide 10 and the end surface of the second waveguide 20 is within 2 mm, the waveguide interface structure 100 can achieve good electrical connection and prevent electromagnetic wave leakage.
A second embodiment of the present invention is directed to a waveguide interface structure 200. As shown in fig. 10, 11, and 12, the second embodiment is substantially the same as the first embodiment, and mainly differs from the first embodiment in that: in the first embodiment, the electrical connection portion 11 includes: the waveguide structure comprises an annular main body part 111 connected with the fixing part 12 and used for being attached to the end face of the first waveguide 10, and a plurality of elastic sheets 112 arranged on the annular main body part 111 at intervals, wherein the plurality of elastic sheets 112 extend along a direction far away from the annular main body part 111 to jointly enclose an opening 30, and the plurality of elastic sheets 112 are used for abutting against the end face of the second waveguide 20. In the second embodiment of the present invention, however, the electrical connection portion 11 includes: a plurality of spring pieces 113 provided on the fixing portion 12 at intervals, and a cylindrical spacer 114 connected to the plurality of spring pieces 113; the spring 113 is used to support the end surface of the second waveguide 20, the cylindrical isolation portion 114 surrounds the opening 30, and the cylindrical isolation portion 114 is used to contact the inner wall of the first waveguide 10. In addition, the technical effects of this embodiment are similar to those of the first embodiment, and are not described herein again.
That is, in the first embodiment, the annular main body 111 and the plurality of elastic pieces 112 respectively abut against the end surface of the first waveguide 10 and the end surface of the second waveguide 20, so as to realize elastic connection and electrical connection between the first waveguide 10 and the second waveguide 20; in the second embodiment, the fixing portion 12 and the plurality of elastic pieces 113 respectively abut against the end surface of the first waveguide 10 and the end surface of the second waveguide 20 to realize elastic connection between the first waveguide 10 and the second waveguide 20, and the cylindrical isolation portion 114 is connected to the plurality of elastic pieces 113 and contacts with the inner wall of the first waveguide 10 to realize electrical connection between the first waveguide 10 and the second waveguide 20.
The following is a detailed description of the implementation details of the waveguide interface structure 200 of the present embodiment, and the following is provided only for the sake of understanding and is not necessary for implementing the present embodiment.
Specifically, the cylindrical spacer 114 may include: the free end of the abutting portion 114b is used for abutting against the inner wall of the first waveguide 10, that is, the cylindrical isolation portion 114 has two opposite end edges (edges at two ends) in the axial direction thereof, the elastic sheet 113 is connected with one end edge (top edge) thereof, and the abutting portion 114b is connected with the other end edge (bottom edge), so that the large-area contact is converted into multi-point contact, the problem of poor contact of a large area is effectively avoided, and the processing precision and the assembly requirement of the abutting portion 114b are reduced.
Further, the abutting portion 114b extends from the end edge or the outer wall surface of the cylinder wall 114a toward the direction away from the inner space of the cylinder wall 114a, so that when the waveguide interface structure 200 connects the first waveguide 10 and the second waveguide 20, the cylinder wall 114a extends into the waveguide port of the first waveguide 10, the abutting portion 114b abuts against the inner wall of the first waveguide 10, the elastic sheet 113 abuts against the end surface of the second waveguide 20, and the elastic sheet 113 is connected with the abutting portion 114b via the cylinder wall 114a, thereby achieving the electrical connection between the first waveguide 10 and the second waveguide 20, and when the size of the interconnection gap between the first waveguide 10 and the second waveguide 20 is changed, the abutting portion 114b can always keep contact with the inner wall of the first waveguide 10 by sliding on the inner wall of the first waveguide 10, and meanwhile, the electromagnetic waves in the electromagnetic wave transmission channel are isolated by the cylinder wall 114a and the abutting portion 114b, thereby avoiding the problem of electromagnetic wave leakage.
In this embodiment, each spring plate 113 includes: a first extending portion 113a connected to the fixing portion 12, a second extending portion 113b bent and extended from the first extending portion 113a, and a third extending portion 113c bent and extended from the second extending portion 113b, wherein the third extending portion 113c is connected to the cylindrical isolation portion 114, and the third extending portion 113c is used for abutting against the end surface of the second waveguide 20, specifically, the third extending portion 113c is connected to one end edge (top edge) of the cylindrical wall 114a, and the abutting portion 114b is connected to the other end edge (bottom edge). Because the second extension portion 113b extends from the first extension portion 113a in a bending manner, the joint between the first extension portion 113a and the second extension portion 113b is more easily elastically deformed, and thus gaps of different sizes between the first waveguide 10 and the second waveguide 20 can be better adapted.
It is understood that the elastic piece 113 may also be other elastic structures, such as a spring, etc., as long as it can be elastically pressed between the end surface of the first waveguide 10 and the end surface of the second waveguide 20, and is not limited herein.
The abutting portion 114b is made of a material, a manufacturing method and a size similar to those of the elastic sheet 112 in the first embodiment, for example, the abutting portion 114b may be made of a metal material, and may be formed by stamping or bending welding after etching (the cylinder wall 114a and the abutting portion 114b are formed together), or the abutting portion 114b is welded to the cylinder wall 114a by using a welding process, if the opening 30 is used for passing electromagnetic waves with a first wavelength, in order to ensure reliable electrical contact, the widths w (i.e., finger widths) of the abutting portions 114b in the arrangement direction along the abutting portion 114b may be less than 0.2 times the first wavelength; according to the objective of leakage prevention, with the cut-off waveguide theory, the distances v (i.e., the finger distances) between adjacent abutting portions 114b in the arrangement direction along the abutting portions 114b may be less than 0.05 times the first wavelength, and the other dimensions of the arrangement will not be described herein.
In practical applications, the materials of the third extending portion 113c and the cylindrical isolation portion 114 (specifically, the cylindrical wall 114a and the abutting portion 114b) are conductive materials, such as metals, so that the first waveguide 10 and the second waveguide 20 are electrically connected via the third extending portion 113c, the cylindrical wall 114a and the abutting portion 114 b. Of course, the third extending portion 113c, the cylindrical wall 114a and the abutting portion 114b may be made of conductive material only on the surface and insulating material (e.g., plastic) on the inside, as long as the conductivity is achieved.
In the waveguide interface structure 200 provided in this embodiment, when the gap absorption capacity is greater than 2 mm, that is, when the distance between the end surface of the first waveguide 10 and the end surface of the second waveguide 20 is not greater than 2 mm, the waveguide interface structure 200 can achieve good electrical connection and prevent electromagnetic wave leakage.
Since the first embodiment corresponds to the present embodiment, the present embodiment can be implemented in cooperation with the first embodiment. The related technical details mentioned in the first embodiment are still valid in this embodiment, and the technical effects that can be achieved in the first embodiment can also be achieved in this embodiment, and are not described herein again in order to reduce the repetition. Accordingly, the related-art details mentioned in the present embodiment can also be applied to the second embodiment.
It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples for carrying out the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in practice.
