Description

Technical Field

[0001] The invention relates to the technical field of microwave ferrite isolators, in particular to a microwave ferrite isolator with a positioning structure. Background Art

[0002] Microwave ferrite isolator is a non-reciprocal two-port microwave ferrite device. When the electromagnetic wave is transmitted in the forward direction, all the power can be fed to the load, and the reflected wave from the load is greatly attenuated. In the design of microwave ferrite isolators, the design of the positioning structure is very important, which directly affects the performance stability, production efficiency and manufacturing cost of the isolator. A reasonable and precise positioning structure can ensure the precise alignment and fixation between the microwave ferrite material, the center conductor and other components, thereby improving the isolation, return loss and other key performance indicators of the isolator.

[0003] In the prior art, there is a microwave ferrite isolator cavity with a publication number of CN209016243U, which relates to the field of isolator cavity design. It achieves the effects of easy production and assembly, high production efficiency, small volume and high integration. The microwave ferrite isolator cavity includes an upper cover plate, a lower cover plate, an isolation device and a connecting device. The lower cover plate is fixedly installed at the bottom end of the upper cover plate, the isolation device is fixedly installed between the upper cover plate and the lower cover plate, and the connecting device is fixedly installed at the connection between the upper cover plate and the lower cover plate. A stepped hole is provided on the top of the shell, and a bolt is movably connected inside the stepped hole. A recessed groove is provided on the top of the shell, and a positioning groove is fixedly installed inside the top of the bottom plate. This type of microwave ferrite isolator cavity is easy to produce and assemble through interference fit and extrusion positioning of the components, has high production efficiency, and increases the internal space of the cavity, thereby reducing the overall volume of the isolator, and has high integration.

[0004] In actual use, although the assembly method between the microwave ferrite isolator cavity and the cover plate has been improved, the connection between the cavity and other components is not tight enough, and there is a lack of elastic structure between the cover plate and the cavity, which causes the cover plate to loosen, affecting the internal components due to the lack of compression, resulting in abnormal conductivity; and the traditional cover plate installation and connector port tight fitting are often two independent steps that need to be performed separately, which is time-consuming. The existing technology cannot achieve the simultaneous tight fitting of the connector port while assembling the cover plate, which easily causes the connector to loosen.

[0005] Therefore, the present invention proposes a microwave ferrite isolator with a positioning structure to solve the problem that the connection between the existing cover plate and the cavity is not tight enough and the assembly efficiency is poor. The cover plate can be assembled while the connector port is simultaneously tight-fitted, and the assembly can be done in one step, thereby improving the assembly speed. Summary of the invention

[0039] Embodiment 3

[0040] On the basis of the second embodiment, in order to achieve the tightness of the connection between the connecting end line 3 and the plate body and avoid the decrease of the conductive performance of the connecting end line 3: the port connection mechanism 4 includes a lower fixing seat 41 and an upper fixing seat 42, the lower fixing seat 41 is provided with two groups, and the two groups of lower fixing seats 41 are respectively fixedly installed on the outer surfaces of both sides of the lower convex plate 12, the upper end outer surface of the lower fixing seat 41 is fixedly connected with a connecting frame 411, and a snap-fitting groove 412 is provided on the inner wall of the connecting frame 411, and the connecting frame 411 is an "mouth"-shaped plate structure as a whole; the upper fixing seat 42 is provided with two groups, and the two groups of upper fixing seats are respectively fixedly installed on the outer surfaces of both sides of the lower convex plate 12, and the upper end outer surface of the lower fixing seat 41 is fixedly connected with a connecting frame 411, and a snap-fitting groove 412 is provided on the inner wall of the connecting frame 411, and the connecting frame 411 is an "mouth"-shaped plate structure as a whole; The fixed seat 42 is respectively fixedly installed on the outer surfaces of both sides of the upper convex plate 22, and the lower end of the upper fixed seat 42 is fixedly connected with an embedding slot plate 421, and the outer surface of the embedding slot plate 421 is movably plugged into the inner surface of the connecting frame 411; a spacing groove 4211 is opened on the outer inner wall of the embedding slot plate 421, and a back plate 422 is fixedly installed on the inner wall of the embedding slot plate 421, and the outer surface of the back plate 422 is fixedly connected with a telescopic spring 4221, and the other end of the telescopic spring 4221 is fixedly connected with a sealing block 423, and the outer surface of the sealing block 423 is movably connected to the inner surface of the card-matching groove 412.

[0041] After limiting the position of the lower plate body 1 and the upper plate body 2, the lower convex plate 12 and the upper convex plate 22 are adapted to be connected. At this time, the slot plate 421 connected to the side of the upper convex plate 22 is inserted into the gap between the side of the lower convex plate 12 and the connecting frame 411. Due to the rounded corner design of the outer edge of the sealing block 423, the sealing block 423 is pushed into the inside of the spacing groove 4211 when it contacts the surface of the connecting frame 411. At this time, the telescopic spring 4221 is in a compressed state from the initial state. Figure 5 and attached Figure 6 As shown, after the bottom end of the slotted slot plate 421 to be inserted is fully in contact with the upper end of the lower fixed seat 41, the sealing block 423 is subjected to the reverse elastic force of the telescopic spring 4221 and is staggered toward the inside of the snap-fitting slot 412, thereby achieving a tight fit between the lower convex plate 12 and the upper convex plate 22, avoiding the presence of gaps in the connector ports, which would affect the normal performance of the conductor elements 6 inside the lower plate body 1 and the upper plate body 2.

[0042] Embodiment 4

[0043] On the basis of Embodiment 3, in order to achieve the locking of the cover plate 72 assembly: The cover plate assembly mechanism 7 includes a limit ring plate 71 and a cover plate 72. The limit ring plate 71 is fixedly installed at the upper end of the upper plate body 2. Embedding grooves 711 and locking grooves 712 are respectively formed on the inner wall of the limit ring plate 71. An activity groove 713 is arranged between the embedding groove 711 and the locking groove 712. The embedding groove 711, the locking groove 712 and the activity groove 713 are all arranged in three groups. A positioning and locking component 73 is arranged inside the locking groove 712; The positioning and locking component 73 includes a receiving groove plate 731. The receiving groove plate 731 is fixedly installed on one side of the locking groove 712. The receiving groove plate 731 is integrally in a "C"-shaped plate structure. A receiving groove 732 is formed on the inner wall of the receiving groove plate 731. An elastic block 733 and a contact spring 735 are arranged inside the receiving groove 732. One end of the contact spring 735 is fixedly connected to the inner wall of the receiving groove plate 731. The elastic block 733 is in an "Ω"-shaped block structure. A return piece 7331 is fixedly connected to the inside of the elastic block 733. One outer surface of one end of the elastic block 733 is movably connected to the inner surface of a reserved hole 730 preset on the inner wall of the receiving groove plate 731; One end of the elastic block 733 is fixedly connected to an insertion block 734. The outer surface of the insertion block 734 is fixedly connected to one end of the contact spring 735. The insertion block 734 is integrally in an "L"-shaped plate structure. An anti-slip block 7341 is fixedly added to the upper surface of the insertion block 734. The lower outer surface of the insertion block 734 is movably connected to a limit block 722.

[0044] When the locking nut 722 is in the state of being lifted up, the operator can lock the locking nut 714 and lock the locking nut 716 with the help of the locking nut 722 so as to enable the locking nut 722 to be locked. When the locking cam 734 is in the state of being lifted up, the locking cam 734 can be locked into position with the locking cam 736 being of sufficient strength to prevent the locking cam 736 from being swung into position and the locking cam 736 being locked to the locking cam 736.

[0045] Embodiment 5

[0046] On the basis of embodiment 4, three groups of limit blocks 722 are provided, and the three groups of limit blocks 722 are fixedly installed on the outer ring surface of the cover plate 72. A buckling groove 721 is opened on the upper inner wall of the cover plate 72. The outer surface of the cover plate 72 is rotatably connected to the inner ring surface of the limit ring plate 71. The lower end of the cover plate 72 is fixedly connected with a connecting ring 723, and the lower end outer surface of the connecting ring 723 is fixedly connected with a locking buckle plate 724; the lower side outer surface of the locking buckle plate 724 is movably connected with an inner edge arc plate 53, and the inner edge arc plate 53 is fixedly installed on the upper inner ring surface of the peripheral wall 52.

[0047] Insert three fingers into the buckle groove 721 opened at the upper end of the cover 72, and use the force of the fingers to rotate the cover 72 as a whole. During the rotation of the cover 72, the connecting ring 723 and the locking buckle plate 724 connected to the lower end rotate synchronously, and then the locking buckle plate 724 slides in from the side of the corresponding inner edge arc plate 53, thereby realizing the assembly between the cover 72 and the cavity 5. When the limit block 722 is locked, the position of the locking buckle plate 724 is no longer active, thereby further ensuring the stability between the cover 72 and the cavity 5 and avoiding looseness, thereby realizing the dual improvement of assembly efficiency and connection tightness, and bringing significant improvements and progress to the production and manufacturing of microwave ferrite isolators.

[0048] In actual use, first, assemble the lower plate body 1 and the upper plate body 2, limit the reserved groove 20 corresponding to the limit column 11 fixedly connected on the lower plate body 1, and then insert the limit sleeve 21 into the corresponding reserved groove 20 for adaptation. The outer side of the limit column 11 is now limited by the insertion of the limit sleeve 21, so as to achieve the rapid limitation of the lower plate body 1 and the upper plate body 2; after the lower plate body 1 and the upper plate body 2 are limited, the lower convex plate 12 and the upper convex plate 22 are adapted to be connected. At this time, the embedded slot plate 421 connected to the side of the upper convex plate 22 is inserted into the gap between the side of the lower convex plate 12 and the connecting frame 411. Due to the rounded corner design of the outer peripheral edge of the sealing block 423, the sealing block 423 is pushed into the inside of the spacing groove 4211 when it contacts the surface of the connecting frame 411. At this time, the telescopic spring 4221 is in a compressed state from the initial state, refer to the attached Figure 5 and attached Figure 6As shown, after the bottom end of the slot plate 421 to be inserted is completely in contact with the upper end of the lower fixing seat 41, the sealing block 423 is subjected to the reverse elastic force of the telescopic spring 4221 and interlaced toward the inside of the snap-fitting groove 412, thereby achieving a tight fit between the lower convex plate 12 and the upper convex plate 22; further, three fingers are inserted into the buckling groove 721 opened at the upper end of the cover plate 72, and after the limit block 722 connected to the outer ring of the cover plate 72 is inserted into the embedding groove 711, the fingers are forced to rotate the cover plate When the locking cam 734 is in the state of being moved, the locking cam 734 is in the state of being moved. The three groups of corresponding plug blocks 734 are thereby released, thereby locking the limit block 722 to prevent the cover plate 72 from loosening and further ensuring the tightness of the connection with the cavity 5; in addition, during the rotation of the cover plate 72, the connecting ring 723 and the locking buckle plate 724 connected to the lower end rotate synchronously, and then the locking buckle plate 724 slides in from the side of the corresponding inner edge arc plate 53, thereby achieving the assembly between the cover plate 72 and the cavity 5, and when the limit block 722 is locked, the position of the locking buckle plate 724 is no longer active, thereby further ensuring the stability between the cover plate 72 and the cavity 5 and avoiding loosening, achieving a dual improvement in assembly efficiency and connection tightness, and bringing significant improvements and progress to the production and manufacturing of microwave ferrite isolators. Finally, when the cover plate 72 needs to be disassembled, it is only necessary to rotate the cover plate 72 in the opposite direction so that the limit block 722 reaches the position of the embedding groove 711, and then lift the cover plate 72 as a whole.
