AI Technical Summary
The existing flange-type RF connector has a simple pin structure, which results in insufficient mating strength between the connector and the mating equipment. Changes in pin size lead to a decrease in mating strength, and the lack of necessary buffering measures affects durability.
The design incorporates a three-section pin structure: a mating section, a first connecting section, a second connecting section, and a third connecting section with progressively increasing outer diameters. This design enhances the fit between the pin and the connector. Additionally, grooves are incorporated on the outer wall, and a C-ring structure is added to the inner side to improve cushioning performance.
It enhances the tight fit between the pins and the mating connector, reduces shaking and loosening, and improves the stability and durability of the connection.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, and in particular to a flange-type radio frequency connector pin. Background Technology
[0002] Currently commonly used flange-type RF connector structures include: Figure 1 and Figure 2 As shown, the existing flange connector has a relatively simple flange pin 100 structure. The groove width of the end of the pin is relatively small, and the outer diameter of the longitudinal mating part is basically unchanged.
[0003] The overly simplistic pin design results in insufficient mating strength between the connector and the mating device. Over time, the original dimensions of the pins will inevitably change, reducing the mating strength. Furthermore, the lack of necessary buffering mechanisms compromises the pins' durability. Therefore, it is necessary to provide a flange-type RF connector pin to solve, or at least partially solve, the aforementioned problems. Utility Model Content
[0004] This utility model provides a flange-type RF connector pin with an optimized structure. The pin features a three-section structure with a mating section and an outer diameter that increases sequentially, enhancing the fit and improving connection stability.
[0005] This utility model provides a flange-type RF connector pin, including a pin body. A positioning boss is provided in the middle of the pin body, and the positioning boss is coaxially arranged with the pin body. The pin body has a first end and a second end, which are symmetrically arranged along the positioning boss. Both the first end and the second end are provided with an insertion hole. The outer walls of both the first end and the second end are provided with a mating section, a first connecting section, a second connecting section and a third connecting section in sequence from the end to the middle. The outer diameters of the first connecting section, the second connecting section and the third connecting section increase in sequence. The outer diameter of the mating section is larger than the outer diameter of the first connecting section and smaller than the outer diameter of the third connecting section. The outer walls of both the first end and the second end are provided with grooves axially.
[0006] Preferably, the grooves are arranged radially through each other, and there are multiple grooves, which are evenly spaced circumferentially.
[0007] Preferably, the groove extends from the end to the middle of the third connecting segment.
[0008] Preferably, the inner wall of the insertion hole is provided with an annular groove, and a C-shaped ring with a notch is provided in the annular groove; when the C-shaped ring is inserted into the annular groove, the outer diameter matches the inner diameter of the annular groove, and the inner diameter is smaller than the inner diameter of the insertion hole; when the C-shaped ring is compressed to the point where the two ends abut, the outer diameter is smaller than the inner diameter of the insertion hole.
[0009] Preferably, mounting holes are provided at both ends of the C-ring.
[0010] Preferably, the insertion holes at the first end and the second end are connected by a through hole, the diameter of which is smaller than the inner diameter of the insertion hole, and the insertion hole forms a mating hole corresponding to the mating section, the inner diameter of which is larger than the inner diameter of the insertion hole.
[0011] Preferably, the edge of the mating section is chamfered, the mating section is connected to the first connecting section by a bevel, the edge of the mating hole is chamfered, and the mating hole is connected to the insertion hole by a bevel to form an inner inclined step.

[0013] Preferably, the third connecting segment has a chamfer at the connection point with the second connecting segment.
[0014] Preferably, the pin body and the positioning boss are integrally formed, and the pin body and the positioning boss are made of metal.
[0015] Compared with the prior art, the technical solution of this utility model has beneficial effects.
[0016] For example, a flange-type RF connector pin includes a pin body with a positioning boss in the middle, coaxially arranged with the pin body. The pin body has a first end and a second end, symmetrically arranged along the positioning boss. Both the first and second ends have insertion holes. The outer walls of both the first and second ends are sequentially arranged from the end to the middle as a mating section, a first connecting section, a second connecting section, and a third connecting section, with the outer diameters of the first, second, and third connecting sections increasing sequentially. The outer diameter of the mating section is larger than that of the first connecting section but smaller than that of the third connecting section. The outer walls of both the first and second ends are axially grooved. The three-section structure of the mating section and the sequentially increasing outer diameters of the first, second, and third connecting sections strengthens the fit between the pin and the connector, making the fit tighter and more precise, reducing pin wobble or loosening, and ensuring connection stability. The widened grooves and the C-ring structure on the inner side of the pin facilitate pin engagement buffering, improving pin durability and connector quality. Attached Figure Description
