Description

Technical Field

[0001] The invention relates to the technical field of coaxial feeder connectors, and in particular to a compensation area impedance fixed radio frequency coaxial feeder connector. Background Art

[0002] The coaxial feeder connector is composed of a connector, a center contact pin, an insulator and a shell. The connector and the shell are used to fix the coaxial cable. When the male connector and the female connector of the existing coaxial feeder connector are mated, when the male step surface and the female end surface are fitted, the mating surface of the male step surface and the female end surface is the electrical and mechanical reference surface, the fitting time distance is the smallest, and the electrical performance is the best; when the mating distance between the male step surface and the female end surface is the largest, such as Figure 5 As shown, the spacing C is the maximum mating spacing, the electrical and mechanical reference planes are separated, and the area formed is a high impedance area. The spacing increases with the increase of the mating spacing. The larger the spacing C, the larger the high impedance area. The electrical performance deteriorates with the increase of the spacing. At the same time, the mechanical contact between the existing male connector and the female connector is deadened by the female end face and the male step surface. During the operation of this kind of matching, due to the operator's strong hand strength, the male step surface and the female end face are easily damaged, resulting in damage to the connection between the female inner conductor and the male inner conductor, reducing the reliability of the connection and the positioning between the two. At the same time, the length of the connecting piece between the female inner conductor and the male inner conductor is short when they are fitted, resulting in a small spacing range of the coaxial feeder connector connection, a small axial tolerance, high production process requirements, and high requirements for the operator; for this reason, a compensation area impedance fixed RF coaxial feeder connector is proposed. Summary of the invention

[0003] The purpose of the present invention is to solve the above problems and to provide a compensation area impedance fixed type radio frequency coaxial feeder connector.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a compensation area impedance fixed radio frequency coaxial feeder connector, a compensation area impedance fixed radio frequency coaxial feeder connector, including a female connector, a male connector adapted to the female connector, the female connector including a female outer conductor, a female insulator connected to the female outer conductor, and a female inner conductor arranged in an inner cavity of the female outer conductor and connected to the female insulator, the male connector including a male outer conductor, a male insulator connected to the male outer conductor, and a male inner conductor arranged in an inner cavity of the male outer conductor and connected to the female insulator. The male inner conductor extending out of the male outer conductor and connected to the male insulator is characterized in that: a female outer conductor step is provided in the female outer conductor, a female inner conductor end face is provided on the female inner conductor, a male outer conductor end face is provided on the male outer conductor, a male inner conductor step is provided on the male inner conductor, a positioning spacing A is provided between the female inner conductor end face and the female outer conductor step, a positioning spacing B is provided between the male outer conductor end face and the male inner conductor step, and both spacing A and spacing B are high impedance compensation areas, and are misaligned high impedance compensation areas.

[0005] Preferably, the female connector and the male connector have no electrical and mechanical reference surface after mating, and the contact surface of the female connector and the male connector after mating is a cylindrical surface.

[0006] Preferably, a U-shaped air section is provided between the female outer conductor and the female inner conductor.

[0007] Preferably, an air section is provided between the inner wall of the male outer conductor and the outer wall of the male inner conductor.

[0008] Preferably, the diameter ratios of the inner diameter of the male outer conductor and the outer diameter of the male inner conductor, the inner diameter of the female outer conductor and the outer diameter of the female inner conductor, and the inner diameter of the female outer conductor and the outer diameter of the male inner conductor are consistent, and the diameter ratio range is between 2.2 and 2.5.

[0009] The beneficial effects of the present invention are as follows: by setting a positioning spacing A on the female connector and setting a positioning spacing B on the male connector, the mating spacing between the female connector and the male connector is changed while the spacing A and the spacing B remain unchanged, and the misaligned high impedance compensation area is fixed and unchanged, thereby ensuring that the voltage standing wave ratio of the female connector and the male connector does not change within the mating spacing range, so that the connection spacing range of the coaxial feeder connector is large, and the operator's connection requirements for the coaxial feeder connector are reduced; Through the design of the structure without electrical and mechanical reference surface, the contact surface of the female connector and the male connector is a circular ring surface when the minimum spacing is matched, which increases the area of ​​the contact surface, making the connection more stable and rigid. By using the air segment as the insulating medium, the standing wave ratio of the coaxial feeder connector is reduced; By making the diameter ratio consistent, the voltage standing wave ratio is made to be a straight line and constant, thus ensuring that the voltage standing wave ratio remains constant.

If the specific posture changes, the directional indication will also change accordingly.

[0014] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0015] See attached Figure 1-4As shown, a compensation area impedance fixed radio frequency coaxial feeder connector includes a female connector 1 and a male connector 2 adapted to the female connector 1, wherein the female connector 1 includes a female outer conductor 13, a female insulator 12 connected to the female outer conductor 13, and a female inner conductor 11 arranged in the inner cavity of the female outer conductor 13 and connected to the female insulator 12, and the male connector 2 includes a male outer conductor 23, a male insulator 22 connected to the male outer conductor 23, and a male inner conductor arranged in the male outer conductor 21 and extending out of the male outer conductor 23 and connected to the male insulator 22 21, characterized in that: the female outer conductor 13 is provided with a female outer conductor step 15, the female inner conductor 11 is provided with a female inner conductor end face 14, the male outer conductor 23 is provided with a male outer conductor end face 25, the male inner conductor 21 is provided with a male inner conductor step 24, a positioning spacing A16 is provided between the female inner conductor end face 14 and the female outer conductor step 15, a positioning spacing B26 is provided between the male outer conductor end face 25 and the male inner conductor step 24, and the spacing A16 and the spacing B26 are both high impedance compensation areas, and are misaligned high impedance compensation areas.

[0016] By setting a positioning spacing A16 on the female connector 1 and a positioning spacing B26 on the male connector 2, the mating spacing between the female connector 1 and the male connector 2 is changed while the spacing A16 and the spacing B26 remain unchanged, and the misaligned high impedance compensation area is fixed, thereby ensuring that the voltage standing wave ratio of the female connector 1 and the male connector 2 does not change within the mating spacing range, so that the connection spacing range of the coaxial feeder connector is large, thereby reducing the operator's connection requirements for the coaxial feeder connector.

[0017] Participate in the Figure 3 , 4 As shown, the female connector 1 and the male connector 2 have no electrical and mechanical reference surface after mating, and the contact surface of the female connector 1 and the male connector 2 after mating is a cylindrical surface; through the design of the structure without electrical and mechanical reference surface, the contact surface of the female connector 1 and the male connector 2 is a circular ring surface when the minimum spacing is mated, which increases the area of ​​the contact surface, making the connection more stable and rigid.

[0018] Participate in the Figure 1-4 As shown, a U-shaped air segment 3 is provided between the female outer conductor 13 and the female inner conductor 11; an air segment 3 is provided between the inner wall of the male outer conductor 23 and the outer wall of the male inner conductor 21; by using the air segment 3 as an insulating medium, the standing wave ratio of the coaxial feeder connector is reduced.

[0019] Participate in the Figure 1 , 2As shown, the diameter ratios of the inner diameter of the male outer conductor 23 and the outer diameter of the male inner conductor 21, the inner diameter of the female outer conductor 13 and the outer diameter of the female inner conductor 11, and the inner diameter of the female outer conductor 13 and the outer diameter of the male inner conductor 21 are consistent, and the diameter ratio range is between 2.2 and 2.5; by making the diameter ratio consistent, the voltage standing wave ratio is made to be a straight line and unchanged, thereby ensuring that the voltage standing wave ratio remains unchanged.

[0020] The reason why the spacing of the present invention remains unchanged is: by setting an A spacing 16 between the female inner conductor end face 14 and the female outer conductor step 15 on the female connector 1, and setting a B spacing 26 between the male inner conductor step 24 and the male outer conductor end face 25 on the male connector 2, the A spacing 16 and the B spacing 26 are inherent in the connector structure, and when the female connector 1 and the male connector 2 are mated with each other, there is no electrical and mechanical reference plane, and the A spacing 16 and the B spacing 26 are misaligned high impedance compensation areas, when the female connector 1 and the male connector 2 are fitted, the spacing is the smallest, and the A spacing 16 and the B spacing 26 remain unchanged; when the spacing between the female connector 1 and the male connector 2 is the largest, the A spacing 16 and the B spacing 26 remain unchanged; therefore, the A spacing 16 and the B spacing 26 will not change with the change of the spacing, and the voltage standing wave ratio can be guaranteed to remain unchanged within the mating spacing range.

[0021] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention belongs to the protection scope of the present invention.
