[0002] Circular connectors are a very important type of connector. They are named because their basic structure is cylindrical and they have a circular mating surface. They are used to provide power, signal and data connection transmission for various equipment and systems. They are widely used in various industries and application fields such as military, aviation, medical, and industry. The terminal assemblies used in existing circular connectors on the market are all cylindrical terminal body arrays inserted into the insulator. The cylindrical terminal body can only be prepared by turning, which has high manufacturing costs. In addition, the assembly space on the insulator is small during assembly, and the terminal bodies are mutually restricted, which makes assembly more difficult. Machine assembly can easily scratch the surface of the terminal body and cause great losses. Manual assembly results in low production efficiency, which makes the assembly cost of the terminal body higher, and the selling price of circular connectors remains high. In addition, due to the limitations of the turning process, the size of the turned terminal body is larger, which makes the terminal assembly and circular connector larger in size and limited in use. Summary of the Invention

[0033] Example 1

[0034] like Figure 1 As shown, during the production of the existing terminal assembly 1, a turning process is adopted to prepare cylindrical terminal bodies 12 one by one. This process results in high production costs and low production efficiency of the terminal body 12. Due to the limitation of the turning process, the size of the terminal body 12 is relatively large. During assembly, the terminal body 12 array is inserted into the insulator 11. This process uses mechanical operation, which is easy to scratch the terminal body 12 and cause large losses. Manual operation will lead to low assembly efficiency. Moreover, due to the large size of the terminal body 12, the overall size of the insulator 11 and the terminal assembly 1 is also large, and the scope of application is limited.

[0035] At the same time, the terminal body 12 needs to be welded with wires at its end when in use. However, since the terminal body 12 is assembled relatively densely, the welding operation needs to be completed manually due to space limitations, further reducing assembly efficiency.

[0036] The terminal assembly provided in this embodiment has a structure as follows Figure 2 As shown, it includes an insulator 11 and a terminal body 12 provided on the outer circumferential wall thereof.

[0037] Based on the above structure, the terminal assembly 1 assembles the terminal body 12 on the outer circumferential wall of the insulator 11, avoiding the limited installation space caused by the existing technology of inserting the cylindrical terminal body 12 array into the insulator 11. It can be installed in a mechanized manner without causing loss of the terminal body 12, simplifying the assembly process and reducing the assembly cost. At the same time, due to the larger space on the outer circumferential wall of the insulator 11, the assembly space of the terminal body 12 is relatively increased, which makes the terminal assembly 1 with the same number of terminal bodies 12 smaller than the conventional terminal assembly and has a wider range of uses.

[0038] In some embodiments of the present application, a limiting groove 13 adapted to the terminal body 12 is provided on the outer circumferential wall of the insulator 11, and the terminal body 12 is located in the limiting groove 13, and the limiting groove 13 increases the stability of the connection between the terminal body 12 and the insulator 11.

[0039] In some embodiments of the present application, the terminal assembly 1 further includes a coaxial assembly 14 , which is disposed within the insulator 11 ; specifically, the coaxial assembly 14 is disposed along the axis of the insulator 11 .

[0040] The number of coaxial components 14 is determined according to the user's needs, and one or two groups can be selected.

[0041] This embodiment provides the coaxial component 14 to ensure that when the terminal component 1 is used in a radio frequency device, there is sufficient impedance matching between the terminal component 1 and the radio frequency device, and the use effect is good.

[0042] In some embodiments of the present application, the terminal body 12 is a flat strip structure; this avoids the problem that the existing cylindrical terminal body can only be prepared by a turning process. The terminal body 12 described in the present invention is prepared by a stamping process, which reduces production costs and its size is not limited by the preparation process. It can further reduce the size of the terminal body 12, thereby reducing the overall size of the terminal assembly 1 and expanding its scope of use.

[0043] like Figure 3 As shown, in some embodiments of the present application, the end of the terminal body 12 is flat, or the end of the terminal body 12 extends radially along the insulator 11 to form a bend 121, or the end of the terminal body 12 is formed with a protrusion 122; when in use, the terminal body 12 with a flat end is arranged in the female seat mechanism, and the terminal body 12 with the bend 121 or the protrusion 122 is arranged in the male head mechanism; or the terminal body 12 with a flat end is arranged in the male head mechanism, and the terminal body 12 with the bend 121 or the protrusion 122 is arranged in the female seat mechanism.

[0044] After the male connector and the female connector are plugged in, the flat end of one terminal body 12 is interference-fitted with the bent portion 121 and the raised portion 122 of the other terminal body 12 to ensure the stability of the connection.

[0045] In some embodiments of the present application, there are at least two terminal bodies 12 , and the at least two terminal bodies 12 are spaced apart and arranged on the outer circumferential wall of the insulator 11 . The extension direction of the terminal body 12 is parallel to the axis of the insulator 11 .

[0046] In this embodiment, the assembly space of the terminal body 12 is the outer circumferential wall of the insulator 11, which has a relatively large range. Therefore, the assembly quantity of the terminal body 12 can be set according to user needs without being limited by the assembly space and assembly process.

[0047] The preparation process of the terminal assembly provided in this embodiment is as follows:

[0048] Cut a sheet of suitable size, and use a stamping process to prepare a terminal body 12 on one side of the sheet. Multiple terminal bodies 12 are connected through the other side of the sheet. During assembly, the insulator 11 is rotated while the sheet is moved to drive the terminal body 12 to move, and the terminal body 12 is assembled in the limiting groove 13 of the outer circumferential wall of the insulator 11; in the present invention, the terminal body 12 is stamped, which reduces the preparation cost and can reduce the size of the terminal body 12; assembling the terminal body 12 on the outer circumferential wall of the insulator 11 can increase its assembly space, so that the number of assemblies is not limited, and it can avoid the narrow operating space caused by arraying multiple terminal bodies 2 in the insulator 11, and automatic welding can be used to weld the terminal body 12 and the wire; at the same time, the present invention also mechanized the assembly of the terminal body 12 and the insulator 11 through the above process, thereby improving the assembly efficiency of the terminal body 12 and the insulator 11 and reducing losses.

[0049] Example 2

[0050] The female seat mechanism provided in this embodiment is as follows: Figure 4 、 Figure 5 As shown, it includes a female socket housing assembly 2 and the terminal assembly 1 described in Example 1, and the terminal assembly 1 is arranged in the female socket housing assembly 2.

[0051] This embodiment fixes the terminal assembly 1 by providing a female socket housing assembly 2, and facilitates the female socket mechanism to be plugged into the male head mechanism.

[0052] In some embodiments of the present application, the female socket housing assembly 2 includes a female socket housing 21 and a fixing member 22, the terminal assembly 1 and the fixing member 22 are arranged in the female socket housing 21, and the terminal assembly 1 is connected to the female socket housing 21 through the fixing member 22.

[0053] Specifically, one end of the fixing member 22 extends into the female socket housing 21 and is connected to the terminal assembly 1 , and the other end is formed with a bent portion, which is connected to the end of the female socket housing 21 .

[0054] In some embodiments of the present application, the end of the female base housing 21 is clamped in the bent portion; specifically, the bent portion is U-shaped and is clamped with the female base housing 21 in an interference fit manner.

[0055] This embodiment positions and protects the terminal assembly 1 by providing a fixing member 22. When connecting the fixing member 22 and the mother socket shell 21, the end of the mother socket shell 21 is first placed in the U-shaped bending portion, and then the mother socket shell 21 and the bending portion are bonded by ultrasonic welding or glue or adhesive to form a stable connection between the fixing member 22 and the mother socket shell 21.

[0056] In some embodiments of the present application, the fixing member 22 is connected to the mother seat shell 21 by a snap-fit manner; a card block is provided on the fixing member 22, and a card slot matching the card block is provided on the mother seat shell 21; or a card block is provided on the mother seat shell 21, and a card slot matching the card block is provided on the fixing member 22; during assembly, the terminal assembly 1 is inserted into the fixing member 22, and then the fixing member 22 is extended into a specific position in the mother seat shell 21, so that the card block is snapped into the card slot to achieve a stable connection between the fixing member 22 and the mother seat shell 21, and then a stable connection between the terminal assembly 1 and the mother seat shell 21 is achieved.

[0057] In some embodiments of the present application, a protective member 4 is also provided on the female base shell 21, and the protective member 4 includes an outer protective ring 41 and an inner protective ring 42. The outer protective ring 41 is arranged on the outer wall of the female base shell 21, and the inner protective ring 42 is arranged on the inner wall of the female base shell 21.

[0058] When the female seat mechanism is plugged into the male head mechanism, the male head mechanism abuts against the inner protective ring 42 to form a sealing structure, preventing rainwater and dust from entering the connector from the connection; when the female seat shell 21 in the female seat mechanism is connected to the device, the outer protective ring 41 abuts against the device, forming a sealing structure at the connection between the two, preventing rainwater and dust from entering the interior of the device from the connection, thereby ensuring the waterproof and dustproof effect of the female seat mechanism.

[0059] Example 3

[0060] This embodiment provides a male connector mechanism, such as Figure 6 、 Figure 7 As shown, it includes a male housing assembly 3 and the terminal assembly 1 described in Example 1, and the terminal assembly 1 is arranged in the male housing assembly 3.

[0061] This embodiment protects the terminal assembly 1 by providing a male housing assembly 3 to prevent damage to the terminal assembly 1 due to external force collision, and the male housing assembly 3 can be plugged into the female housing assembly 2 to achieve the plug-in connection between the male mechanism and the female mechanism.

[0062] In some embodiments of the present application, the male housing assembly 3 includes an outer housing 31 and an inner housing 32 , the outer housing 31 is sleeved on the inner housing 32 , and the terminal assembly 1 is disposed in the inner housing 32 .

[0063] This embodiment fixes the terminal assembly 1 in the inner shell 32, protects the terminal assembly 1 through the inner shell 32, and limits the outer shell 31, so that the outer shell 31 can move along the axis of the male head mechanism on the inner shell 32, thereby realizing the insertion and separation of the male head mechanism and the female seat mechanism.

[0064] In some embodiments of the present application, the male head mechanism also includes a guide member 321, which is arranged on the outer wall of the inner shell 32, and a limiting hole 311 that cooperates with the guide member 321 is provided on the outer shell 31; specifically, the guide member 321 is located in the limiting hole 311, and when the outer shell 31 is moved along the axis of the male head mechanism relative to the inner shell 32, the guide member 321 limits the outer shell 31 by limiting the moving direction of the limiting hole 311, thereby preventing the outer shell 31 from rotating.

[0065] like Figure 8 As shown, in some embodiments of the present application, a limiting groove 322 for limiting the outer shell 31 is provided on the outer wall of the inner shell 32, and a limiting member 312 is provided on the inner wall of the outer shell 31. The limiting member 312 is located in the limiting groove 322. When the male head mechanism and the female seat mechanism are plugged into each other, the outer shell 31 is pushed relative to the inner shell 32. The limiting groove 322 can prevent the outer shell 31 and the female seat from being plugged in too tightly or too loosely, resulting in poor plugging stability.

[0066] In some embodiments of the present application, the male head mechanism further includes a cable positioning assembly 5 , one end of which is located in the outer shell 31 and fixedly connected to the inner shell 32 .

[0067] When in use, the cable passes through the cable positioning assembly 5 and is connected to the terminal assembly 1 in the inner shell 32. The cable is clamped by the cable positioning assembly 5 and fixedly connected to the inner shell 32, which can indirectly improve the connection strength between the cable and the terminal assembly 1 and prevent the cable from being separated from the terminal assembly 1 due to external force.

[0068] In some embodiments of the present application, the cable positioning assembly 5 includes a tail cover 52 and a wire clamp 51 arranged in the tail cover 52. The inner wall of one end of the tail cover 52 tightens the wire clamp 51 toward the axial direction of the male head mechanism, and the other end is fixedly connected to the inner shell 32.

[0069] Specifically, the other end of the tail cover 52 is threadedly connected to the inner shell 32. During the connection process, the tightened end of the inner wall of the tail cover 52 tightens the wire clamp 51 toward the axis of the male head mechanism, thereby prompting the wire clamp 51 to clamp the cable passing through it, thereby realizing the connection between the cable and the inner shell 32.

[0070] In some embodiments of the present application, the tightened end of the inner wall of the tail cover 52 extends to the outside of the outer shell 31 , so as to facilitate the user to manually install and remove the cable positioning assembly 5 .

[0072] This embodiment provides a circular connector, such as Figure 9 As shown, it includes the female seat mechanism described in Example 2 and the male head mechanism described in Example 3, and the female seat mechanism and the male head mechanism are plugged into each other.

[0073] In some embodiments of the present application, when the end of the terminal body 12 in the female seat mechanism is flat, it cooperates and connects with the bent portion 121 and the raised portion 122 at the end of the terminal body 12 in the male head mechanism; when the end of the terminal body 12 in the female seat mechanism is a bent portion 121 or a raised portion 122, it cooperates and connects with the flat end of the terminal body 12 in the male head mechanism.

[0074] In this embodiment, one end of the two terminal bodies 12 in the female socket mechanism and the male head mechanism is flat, and the other is a bent portion 121 or a raised portion 122. When the female socket mechanism and the male head mechanism are plugged in, the flat end is interference fit with the bent portion 121 and the raised portion 122 to ensure the stability of signal transmission.

[0075] In some embodiments of the present application, a positioning groove is provided in the female socket housing assembly 2, and a positioning piece matching the positioning groove is provided in the male head housing assembly 4.

[0076] During the process of plugging the female mechanism and the male mechanism together, the positioning piece is inserted into the positioning groove to prevent the female mechanism and the male mechanism from being too tight or loose, thereby improving the connection stability between the two, ensuring stable contact between the terminal bodies 12 on the female mechanism and the male mechanism, and improving the stability of signal transmission using the circular connector.
