Description

Technical Field

[0001] The present invention relates to the technical field, and in particular to a packaging structure of a combined isolator and circulator. Background Art

[0002] Isolators and circulators mainly play the role of ring, isolation, amplitude modulation, etc. in microwave circuits, and are mainly used in radar systems, communications and other fields. At present, isolators and circulators are mostly packaged in the traditional way of threaded locking. With the popularization and development of 5G technology, the shortcomings of existing isolators and circulators are: 1. The wall thickness of the packaging shell needs to be designed to be relatively thick to meet the threaded locking requirements, which leads to complex shell design and high cost. In actual production, the shell has poor reusability and high scrapping cost; 2. With the development trend of miniaturization of 5G products, the current thick-walled packaging method has a large space occupancy rate, which greatly affects the product design indicators and increases the product manufacturing cost. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a packaging structure of a combined isolator and circulator, which has the advantages of simplifying design requirements and improving manufacturing costs.

[0004] To achieve the above object, the technical solution of the present invention is as follows:

[0005] A packaging structure of a combined isolator and circulator, comprising:

[0006] A packaging shell, wherein the packaging shell is provided with at least two locking grooves arranged at intervals, and an internal thread is provided at a port of the packaging shell;

[0007] A connecting ring disposed at the bottom of the encapsulating shell and fixed to the encapsulating shell by injection molding, the connecting ring being tightened to the outer side of the encapsulating shell, the connecting ring being provided with connecting protrusions corresponding to the locking grooves one by one, the connecting protrusions being embedded in the locking grooves, and the connecting protrusions being provided with connecting holes, wherein the connecting holes are inserted with grounding pins;

[0008] An inner sealing member is arranged in the packaging shell, the inner sealing member is provided with a locking piece corresponding to the connecting protrusion, the locking piece is provided with a locking hole for inserting the grounding pin, and the top of the inner sealing member is also provided with a limiting protrusion corresponding to the locking groove; and

[0009] A packaging cover is arranged in the inner cavity of the packaging shell and located above the inner sealing member. An outer peripheral wall of the packaging cover is provided with an outer thread matching the inner thread, and an operating hole is opened on the packaging cover.

[0010] To implement the above technical solution, after the processing of the packaging shell is completed, the connecting ring is injection-molded and fixed on the packaging shell through a mold. During packaging, the inner sealing part is placed in the packaging shell, the grounding pin is inserted into the connecting hole, and plugged into the locking hole. At the same time, the limiting protrusion cooperates with the locking groove to limit the rotation of the inner sealing part. Then, the packaging cover is threadedly connected to the packaging shell through the operating hole, and the inner sealing part is pressed and fixed in the packaging shell. Since the connecting ring is tightened on the outside of the packaging shell, the packaging shell can be prevented from expanding outward during the locking process of the packaging cover, and since the connecting protrusion is embedded in the locking groove, Therefore, the connecting ring will not rotate during the screwing process of the packaging cover, so that the packaging fixing effect is better, and at the same time, when the packaging cover is screwed until it is tightly against the inner seal, the limiting effect of the connecting ring can effectively prevent the packaging shell from expanding outward due to thread friction; through the above-mentioned arrangement, the packaging shell can be designed to be thinner during design and processing, which reduces the design difficulty and processing cost, and reduces the space occupancy rate. At the same time, the connecting ring can be fixedly assembled with the packaging shell during processing of the packaging shell, and the injection molding process is also faster and more convenient, thereby improving the processing and assembly efficiency.

[0011] As a preferred solution of the present invention, the connecting protrusion protrudes from the outer peripheral wall of the connecting ring.

[0012] By implementing the above technical solution, the structural strength of the connecting ring can be improved by connecting the protrusions.

[0013] As a preferred solution of the present invention, the width of the connecting ring along the diameter direction is 0.5-1.0 mm, and the thickness of the connecting ring is 0.8-2.5 mm.

[0014] As a preferred solution of the present invention, the width of the connecting protrusion along the diameter direction is 1.5-3.5 mm, and the width along the circumferential direction is 2.5-4 mm.

[0015] As a preferred solution of the present invention, the connecting ring is made of PPS or PFA plastic material.

[0016] As a preferred solution of the present invention, the wall thickness of the packaging shell is 0.5-1.2 mm.

[0017] As a preferred solution of the present invention, the packaging shell is made of carbon steel.

[0018] As a preferred solution of the present invention, the thickness of the packaging cover is 0.8-1.5 mm.

[0019] As a preferred solution of the present invention, the packaging cover is made of magnetic stainless steel.

[0020] In summary, the present invention has the following beneficial effects:

[0021] The embodiment of the present invention provides a packaging structure of a combined isolator and circulator, comprising: a packaging shell, the packaging shell is provided with at least two locking grooves arranged at intervals, and an internal thread is provided at the port of the packaging shell; a connecting ring arranged at the bottom of the packaging shell and fixed to the packaging shell by injection molding, the connecting ring is tightened to the outer side of the packaging shell, the connecting ring is provided with connecting protrusions arranged in a one-to-one correspondence with the locking grooves, the connecting protrusions are embedded in the locking grooves, and the connecting protrusions are provided with connecting holes, and a grounding pin is inserted in the connecting hole; an inner sealing member arranged in the packaging shell, the inner sealing member is provided with a locking sheet corresponding to the connecting protrusion, the locking sheet is provided with a locking hole for inserting the grounding pin, and the top of the inner sealing member is also provided with a limiting protrusion corresponding to the locking groove; and a packaging cover arranged in the inner cavity of the packaging shell and located above the inner sealing member, the outer peripheral wall of the packaging cover is provided with an external thread matching the internal thread, and the packaging cover is provided with an operating hole. After the processing of the packaging shell is completed, the connecting ring is injection-molded and fixed on the packaging shell through a mold. During packaging, the inner sealing part is placed in the packaging shell, the grounding pin is inserted into the connecting hole, and plugged into the locking hole. At the same time, the limiting protrusion cooperates with the locking groove to limit the rotation of the inner sealing part. Then, the packaging cover is threadedly connected to the packaging shell through the operating hole, and the inner sealing part is pressed and fixed in the packaging shell. Since the connecting ring is tightened on the outside of the packaging shell, the packaging shell can be prevented from expanding outward during the locking process of the packaging cover, and since the connecting protrusion is embedded in the locking groove, the inner sealing part is locked during the packaging process. The connecting ring will not rotate during the screwing of the cover, so that the packaging fixing effect is better, and at the same time, when the packaging cover is screwed until it is tightly against the inner seal, the limiting effect of the connecting ring can effectively prevent the packaging shell from expanding outward due to thread friction; through the above-mentioned arrangement, the packaging shell can be designed to be thinner during design and processing, which reduces the design difficulty and processing cost, and reduces the space occupancy rate. At the same time, the connecting ring can be fixed and assembled with the packaging shell during processing of the packaging shell, and the injection molding process is also faster and more convenient, thereby improving the processing and assembly efficiency.

[0032] Specifically, in the present embodiment, three locking grooves 11 are provided, and the three locking grooves 11 are evenly distributed, so that the packaging shell 1 forms a three-petal structure. Of course, in other embodiments, two or four locking grooves 11 can be provided, and the locking grooves 11 can be evenly or unevenly arranged. The wall thickness of the packaging shell 1 is 0.5-1.2 mm. In the present embodiment, the thickness of the packaging shell 1 is set to 0.8 mm, and the packaging shell 1 is made of carbon steel.

[0033] The connecting ring 2 and the connecting protrusion 21 are integrally injection molded. The connecting ring 2 is made of PPS or PFA plastic material. Polyphenylene sulfide (PPS) is a new high-performance thermoplastic resin with the advantages of high mechanical strength, high temperature resistance, chemical resistance, flame retardancy, good thermal stability, and excellent electrical properties. PFA plastic is a copolymer of a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. The connecting protrusion 21 protrudes from the outer peripheral wall of the connecting ring 2. The structural strength of the connecting ring 2 can be improved by the connecting protrusion 21; the width of the connecting ring 2 along the diameter direction is 0.5-1.0mm, the thickness of the connecting ring 2 is 0.8-2.5mm, the width of the connecting protrusion 21 along the diameter direction is 1.5-3.5mm, and the width along the circumferential direction is 2.5-4mm.

Then, the packaging cover 4 is threadedly connected to the packaging shell 1 through the operating hole 42, and the inner sealing part 3 is pressed and fixed in the packaging shell 1. Since the connecting ring 2 is tightened on the outside of the packaging shell 1, the packaging shell 1 can be prevented from expanding outward during the locking process of the packaging cover 4, and since the connecting protrusion 21 is embedded in the locking groove 11, so the connecting ring 2 will not rotate during the screwing of the packaging cover 4, so that the packaging fixing effect is better, and at the same time, when the packaging cover 4 is screwed to be tightly against the inner sealing member 3, the limiting effect of the connecting ring 2 can effectively prevent the packaging shell 1 from expanding outward due to thread friction; through the above-mentioned arrangement, the packaging shell 1 can be designed to be thinner during design and processing, which reduces the design difficulty and processing cost, and reduces the space occupancy rate. At the same time, when the packaging shell 1 is processed, the connecting ring 2 can be fixedly assembled with the packaging shell 1, and the injection molding process is also faster and more convenient, thereby improving the processing and assembly efficiency.
