Description

Technical Field

[0001] The present invention belongs to the technical field of connectors, and in particular relates to a male head mechanism and a circular connector using the same. Background Art

[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 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 existing circular connectors on the market are composed of a male mechanism and a female mechanism that are plugged in. However, since the overall structure of the male mechanism and the female mechanism is cylindrical, and the male mechanism mostly adopts the method of matching the inner shell and the outer shell to form the male shell. When the inner shell and the outer shell are matched and connected, the two often rotate relative to each other, which makes it easy for the male mechanism to be applied to the circular connector, resulting in poor transmission effect of the circular connector. Summary of the Invention

[0003] The purpose of the present invention is to provide a male head mechanism and a circular connector using the same, which solves the problem that the inner shell and the outer shell of the existing male head mechanism often rotate relative to each other, resulting in poor transmission effect of the circular connector when the male head mechanism is used in the circular connector.

[0004] In order to achieve the above-mentioned purpose, the first technical solution of the present invention is implemented as follows: a male head mechanism includes a terminal assembly, an inner shell, an outer shell and a guide member, the terminal assembly is arranged in the inner shell, the outer shell is sleeved on the inner shell and is matched with the guide member.

[0005] Furthermore, the guide member is arranged on the outer wall of the inner shell, and the outer shell is provided with a limiting hole that matches the guide member.

[0006] Furthermore, a limiting member is provided on the inner wall of the outer shell, and a limiting groove matching with the limiting member is provided on the outer wall of the inner shell.

[0007] Furthermore, the male head mechanism also includes a cable positioning assembly, one end of which is located in the outer shell and connected to the inner shell.

[0008] Furthermore, the cable positioning assembly includes a tail cover and a wire clamp arranged in the tail cover, one end of the tail cover extends to the outside of the outer shell, and its inner wall tightens the wire clamp toward the axial direction of the male head mechanism, and the other end is connected to the inner shell.

[0009] Furthermore, the terminal assembly includes an insulator, a terminal body, and a coaxial assembly, wherein the terminal body is disposed on the outer circumferential wall of the insulator, and the coaxial assembly is disposed within the insulator. Furthermore, the outer circumferential wall of the insulator is further provided with a limiting groove adapted to the terminal body, and the terminal body is located within the limiting groove.

[0010] Furthermore, the end of the terminal body is flat, or the end of the terminal body extends along the radial direction of the insulator to form a bent portion, or the end of the terminal body is formed with a protrusion.

[0011] Furthermore, there are at least two terminal bodies, and at least two terminal bodies are arranged at intervals on the outer circumferential wall of the insulator.

[0012] The first technical solution of the present invention is implemented as follows: a circular connector includes a female seat mechanism and the above-mentioned male head mechanism, and the female seat mechanism is adapted to the male head mechanism.

[0013] Compared with the prior art, the present invention has the following beneficial effects: the male head mechanism of the present invention fixes and protects the terminal assembly by setting an inner shell and an outer shell, and prevents the outer shell and the inner shell from rotating during use by sleeves being placed on the inner shell and cooperating with the guide member, thereby promoting relative stability of the two in the circumferential direction. When the male head mechanism is applied to a circular connector, the transmission effect of the circular connector is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Example 1

[0027] This embodiment provides a male connector mechanism, such as Figure 1 As shown, it includes a terminal assembly 1, an inner shell 2, an outer shell 3 and a guide member 4. The terminal assembly 1 is arranged in the inner shell 2, and the outer shell 3 is sleeved on the inner shell 2 and is matched with the guide member 4.

[0028] Based on the above structure, the male head mechanism fixes and protects the terminal assembly 1 by setting an inner shell 2 and an outer shell 3. By sleeved on the inner shell 2 and cooperating with the guide 4, the outer shell 3 and the inner shell 2 are prevented from rotating during use, so that the two are relatively stable in the circumferential direction. When the male head mechanism is applied to a circular connector, the transmission effect of the circular connector is improved.

[0029] like Figure 2 As shown, in some embodiments of the present application, the guide member 4 is provided on the outer wall of the inner shell 2 , and a limiting hole 31 matching with the guide member 4 is provided on the outer shell 3 .

[0030] Specifically, the guide member 4 is located in the limiting hole 31. When the outer shell 3 slides on the inner shell 2 along the axis thereof, the limiting hole 31 always slides along the guide member 4, preventing the outer shell 3 from rotating relative to the inner shell 2 during movement, thereby ensuring the relative stability of the two in the circumferential direction.

[0031] like Figure 3 As shown, in some embodiments of the present application, a limiting member 32 is provided on the inner wall of the outer shell 3 , and a limiting groove 21 that cooperates with the limiting member 32 is provided on the outer wall of the inner shell 2 .

[0032] This embodiment limits the limiting member 32 by setting a limiting groove 21 on the outside of the inner shell 2, which can ensure the relative position of the outer shell 3, the inner shell 2 and the terminal assembly 1 in the axial direction of the male head mechanism, and avoid the outer shell 3 extending too far into the female seat mechanism when the male head mechanism and the female seat mechanism are plugged together, thereby preventing the terminal assembly 1 from being incompletely contacted with the female seat mechanism, or the terminal assembly 1 from being incompletely contacted with the female seat mechanism while the outer shell 3 is incompletely contacted with the female seat mechanism. While ensuring the stable contact between the terminal assembly 1 and the female seat mechanism, the connection strength between the outer shell 3 and the female seat mechanism is guaranteed.

[0033] 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 3 and connected to the inner shell 2 .

[0034] During use, the male head mechanism needs to extend the cable into the inner shell 2 and connect it to the terminal assembly 1. When the cable is pulled by external force, it is easy to disconnect from the terminal assembly 1, causing the male head mechanism to fail. Therefore, this embodiment clamps the cable in it by setting a cable positioning assembly 5, and connects the cable positioning assembly 5 to the inner shell 2. When the cable is pulled by external force, the cable positioning assembly 5 and the inner shell 2 will decompose the force they bear, avoiding the force directly acting on the connection between the cable and the terminal assembly 1, thereby ensuring the stability of the connection between the cable and the terminal assembly 1.

[0035] 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 connected to the inner shell 2.

[0036] Specifically, one end of the wire clamp 51 abuts against the inner shell 2, and the other end abuts against the tightened end of the inner wall of the tail cover 52, and the side wall of the other end of the wire clamp 51 is composed of multiple clamping strips arranged at circumferential intervals. During the connection between the tail cover 52 and the inner shell 2, the wire clamp 51 cannot give way in the axial direction of the male head mechanism, so the multiple clamping strips shrink toward the axis to avoid the movement of the tail cover 52, thereby clamping the cable passed through the wire clamp 51 and realizing an indirect connection between the cable and the inner shell 2.

[0037] There is a gap between the wire clamp 51 and the cable. The deviation of the wire clamp 51 during the use of the cable positioning assembly 5 will cause inconvenience in operation. Therefore, a limiting ring is provided at the end of the inner shell 2, and one end of the wire clamp 51 abuts against the limiting ring to ensure its stability.

[0038] 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 3, so that the user can conveniently twist the tail cover 52 to tighten and loosen the cable.

[0039] like Figure 4 As shown, in some embodiments of the present application, the terminal assembly 1 includes an insulator 11 and a terminal body 12 provided on the outer circumferential wall thereof.

[0040] This embodiment uses the outer circumferential wall of the insulator 11 as the assembly space for the terminal body 12. On the one hand, it can avoid the limitation of the operating space caused by the array of the terminal body 12 passing through the insulator 11, and facilitates the use of automated methods to assemble the terminal body 12 and the insulator 11, as well as the use of automatic welding to weld wires at the end of the terminal body 12, thereby improving assembly efficiency; on the other hand, by increasing the assembly space, the number of terminal bodies 12 assembled on the insulator 11 of the same size can be increased, or the size of the insulator 11 when assembling the same number of terminal bodies 12 can be reduced, thereby reducing the size of the male head mechanism and expanding its scope of use. The more terminal bodies 12 there are, the more obvious the advantages of this embodiment are.

[0041] In some embodiments of the present application, a limiting groove 13 adapted to the terminal body 12 is further provided on the outer circumferential wall of the insulator 11 , and the terminal body 12 is located in the limiting groove 13 .

[0042] Specifically, the shape and number of the limiting grooves 13 are adapted to those of the terminal body 12 .

[0043] This embodiment increases the stability of the connection between the terminal body 12 and the insulator 11 through the limiting groove 13, and ensures that when the terminal assembly 1 is assembled in the inner shell 2, the outer circumferential wall of the insulator 11 is in stable contact with the inner circumferential wall of the inner shell 2 without any gap, thereby preventing water vapor, dust, etc. from entering the male head mechanism from here.

[0044] like Figure 5 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 bent portion 121, or the end of the terminal body is formed with a protrusion 122.

[0045] Specifically, the terminal body 12 is a flat strip-shaped structure as a whole, which can be prepared by a stamping process, breaking the limitation that the existing cylindrical terminal body can only be prepared by a turning process, improving the production efficiency of the terminal body 12, reducing production costs, and reducing the size of the terminal body 12, thereby reducing the size of the terminal assembly 1 and the male head mechanism, and expanding its scope of use.

[0046] The end of one terminal body 12 is set to be flat, and a bending portion 121 or a protruding portion 122 is set at the end of the other terminal body 12. When the two terminal bodies 12 are in contact, the flat end is interference fit with the bending portion 121 and the protruding portion 122 to ensure the stability of the contact.

[0047] In some embodiments of the present application, the terminal assembly 1 further includes a coaxial assembly 14 , which is disposed in the insulator 11 .

[0048] 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.

[0049] The number of coaxial components 14 is determined according to the user's needs, and one or two groups can be selected.

[0050] In some embodiments of the present application, there are at least two terminal bodies 12 , and the at least two terminal bodies 12 are arranged on the outer circumferential wall of the insulator 11 at intervals.

[0051] The use of a stamping process to prepare the terminal body 12 can reduce its size, and the assembly space on the outer circumferential wall of the insulator 11 is larger. Therefore, the number of terminal bodies 12 can be determined according to user needs and is less restricted by size and assembly space.

[0052] The method of using a male head mechanism provided in this embodiment is specifically as follows: before use, cut a plate of appropriate size, and use a stamping process to prepare a terminal body 12 on one side of the plate. Multiple terminal bodies 12 are connected through the other side of the plate. During assembly, the insulator 11 is rotated while the plate is moved to drive the terminal body 12 to move, and the terminal body 12 is assembled in the limiting groove 13 on the outer circumferential wall of the insulator 11 to form a terminal assembly 1; then, the terminal assembly 1 is set in the inner shell 2, and a limiting groove 21 is provided on the outer wall of the inner shell 2. The limiting piece 32 provided on the inner side wall of the outer shell 3 is movably connected in the limiting groove 21. When in use, the outer shell 3 is pushed to move along the axis of the male head mechanism. At this time, the guide piece 4 on the outer wall of the inner shell 2 limits the moving direction of the limiting hole 31, thereby preventing the outer shell 3 from rotating, thereby avoiding poor insertion effect caused by the rotation of the outer shell 3 during the insertion process of the male head mechanism and the female seat mechanism.

[0053] In addition, the present invention connects the tail cover 52 to the inner shell 2. During this process, the tightened part of the inner wall of the tail cover 52 pushes the wire clamp 51 to tighten toward the axis of the male head mechanism, thereby clamping the cable passing through it. When external force pulls the cable, the wire clamp 51 can buffer the force it bears, avoiding it from directly acting on the connection between the cable and the terminal assembly 1, thereby ensuring the stability of the connection between the cable and the terminal assembly 1.

[0054] Example 2

[0055] A circular connector provided in this embodiment includes a female socket mechanism and the male head mechanism described in Example 1. The female socket mechanism is adapted to the male head mechanism, and the transmission of power, signals and data is achieved by plugging the female socket mechanism and the male head mechanism together.

[0056] When the circular connector is in use, the end of the terminal body 12 in the female seat mechanism is set to be flat, and a bent portion 121 or a raised portion 122 is formed at the end of the terminal body 12 in the male head mechanism; or a bent portion 121 or a raised portion 122 is formed at the end of the terminal body 12 of the female seat mechanism, and the end of the terminal body 12 of the male head mechanism is set to be flat; when the female seat mechanism and the male head mechanism are docked, the flat end of the terminal body 12 and the corresponding bent portion 121 and raised portion 122 are interference fit, so that the stability of the power supply, signal and data transmission between the female seat mechanism and the male head mechanism is improved.

[0057] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
