Description

Technical Field

[0001] The invention belongs to the technical field of connectors, and in particular relates to an audio coaxial socket with a switch. Background Art

[0002] A coaxial socket is a common passive radio frequency connector used to establish electrical and mechanical connections between coaxial cables and other coaxial devices. It is widely used in television and broadcast antenna systems, satellite reception systems, cable television networks, wireless communication systems and other fields. Coaxial sockets are reliable, anti-interference, and can transmit signals well in high-frequency environments. Whether in home or industrial fields, coaxial sockets are a common connector choice. Switching audio is an electronic device used to control and switch audio signals. It switches and controls audio signals by switching and selecting different audio inputs or outputs. Today's home audio and video systems, radio and television systems, and monitoring systems mostly use coaxial sockets with switching audio functions. Generally speaking, the plugs that match the switching audio coaxial sockets are mostly slender, which can effectively improve signal quality and reduce signal reflection and loss.

[0003] Patent document CN113690698B discloses a coaxial socket connector, comprising: a central terminal, comprising a central contact portion and a contact pin, wherein the central contact portion is mechanically and electrically connected to a core wire terminal coupled to a plug connector, and the contact pin is electrically connected to a docking circuit board; an external terminal, comprising an outer ring portion and a docking pin, wherein the outer ring portion surrounds the central contact portion and is mechanically and electrically connected to an external conductor surrounding the core wire terminal, and the docking pin is electrically connected to the docking circuit board; a spacer terminal, comprising a shielding portion and a contact portion, wherein the shielding portion is located between the central contact portion and the outer ring portion along a radial direction of the central contact portion, and the contact portion is electrically connected to the docking circuit board; an electrical insulator, which electrically insulates the central terminal, the external terminal and the spacer terminal into one; thus, the shielding effect and high-frequency characteristics are better.

[0004] The above patent documents have improved the shielding effect and high-frequency characteristics, but the plugs used in audio scenarios in the prior art are mostly slender and are frequently plugged in and out. If a clearance fit is adopted between the plug and the center pin assembly, the two are easy to fall off, resulting in poor contact or no contact, affecting the overall effect. If an interference fit is adopted, plugging and unplugging will be time-consuming and laborious, and the plug-in and unplugging point of the center pin assembly will be easily deformed after a period of use, making subsequent plugging and unplugging increasingly difficult. At the same time, the connection between the coaxial socket and the connecting plate in the prior art is mostly in the form of bolt connection. Long-term plugging and unplugging can easily cause the bolt connection to loosen, and may even cause the coaxial socket to separate from the connecting plate, affecting the normal use of the coaxial socket.

The first box body 710 and the first end cover 720 are connected by bolts.

The movable push rod 750 is located inside the first box body 710. The first box body 710 is connected to the first air pipe 711 and the second air pipe 712. Valves (not shown in the figure) are provided on the first air pipe 711 and the second air pipe 712.

[0031] The movable push rod 750 is in the shape of an I-beam, and a locking block 751 is provided at one end of the movable push rod 750 away from the first end cover 720.

[0032] The lifting assembly 800 includes a second box body 810, a second end cover plate 820, a second spring 830, a piston rod 840, a third end cover 850 and a fixed connecting plate 860; the second box body 810 is connected to the second end cover plate 820 at the bottom, the third end cover 850 is connected to the top of the second box body 810, the third end cover 850 is connected to the top of the third end cover 850, the fixed connecting plate 860 is connected to the outer shell assembly 300, the second spring 830 is located inside the second box body 810, the piston rod 840 passes through the second spring 830 and the second end cover plate 820, the second box body 810 is connected to the third air pipe 811 and the fourth air pipe 812, and valves (not shown in the figure) are provided on the third air pipe 811 and the fourth air pipe 812, and the follower assembly 900 also includes a rotating plate 920 and a follower frame 930, the rotating plate 920 is rotatably connected to the piston rod 840, and the follower frame 930 is fixedly connected to the rotating plate 920.

[0033] The piston rod 840 divides the interior of the lifting assembly 800 into area c and area d, wherein area d is located at the top of area c, the third air pipe 811 is connected to area c, and the fourth air pipe 812 is connected to area d. A second groove 841 is provided at the end of the piston rod 840 close to the rotating plate 920, and fourth through holes 842 are provided on both sides of the second groove 841. A third groove 911 is provided on the fixed frame 910, and a fourth groove 921 is provided on the rotating plate 920. A fifth through hole 922 is provided at the end of the rotating plate 920 away from the fixed frame 910, and a spherical end 923 is provided at the end of the rotating plate 920 close to the fixed frame 910. When the air pressure in area d is greater than the air pressure in area c, the piston rod 840 is pushed to move downward, and the rotating plate 920 is deflected.

[0034] It is not difficult to understand that the spherical end 923 of the rotating plate 920 is placed on the fixed frame 910, and a limit frame (not shown in the figure) is usually added to the spherical end 923 so that the rotating plate 920 can only deflect around the center of the spherical end 923. When the piston rod 840 descends, if there is no restriction from the fixed frame 910, the rotating plate 920 will descend as the piston rod 840 descends. However, since the fixed frame 910 is detachably connected to the housing assembly 300, when the piston rod 840 descends, the rotating plate 920 deflects around the center of the spherical end 923, and the threaded connection between the piston rod 840 and the rotating plate 920 slides along the axis of the fourth groove 921, and the position of the follower frame 930 descends, and at the same time, the follower frame 930 approaches the center of the housing assembly 300 in the horizontal direction. When the lifting assembly 800 is reset, the piston rod 840 rises, and the rotating plate 920 deflects around the center of the spherical end 923.

[0035] It should be noted that, refer to the attached Fig.15 and attached Fig.16, although the rotating plate 920 and the follower frame 930 are connected by bolts, in practice, the relative positions of the rotating plate 920 and the follower frame 930 are fixed. Since the present invention uses two pressing components to press the plug 600, it is necessary to perform the initial calibration when determining the relative position. During the initial calibration, the plug 600 is pressed by the two pressing components. At this time, the follower frame 930 is in a vertical state. If it is not vertical, the bolts between the rotating plate 920 and the follower frame 930 can be loosened to make the follower frame 930 in a vertical state and then locked. That is to say, when the air pressures in the c area and the d area of ​​the lifting assembly 800 are equal, as shown in the attached Fig.15 As shown in FIG. 1 , the follower frame 930 is in a non-vertical state. In practice, since the plug 600 and the center pin assembly 500 are clearance-matched, the distance between the follower frame 930 and the plug 600 is small, that is, the following Fig.15 and attached Fig.16 The actual deflection angle of the middle rotating plate 920 is relatively small, generally between 5-8 degrees. In order to ensure that the follower frame 930 does not interfere with the plug 600 during the recovery process, a groove is usually provided on the lower half of the inner wall of the follower frame 930.

[0036] It is not difficult to understand that the maximum pressure of the compressed air source in the factory area is usually around 5 bar. When the transverse moving assembly 700 and the lifting assembly 800 are assembled, the initial pressure of the a and b areas of the transverse moving assembly 700 is usually 3 bar, and the initial pressure of the c and d areas of the lifting assembly 800 is also 3 bar. When the guide plate assembly 200 is positioned, the air pressure in the b area of ​​the transverse moving assembly 700 is usually increased to 5 bar, so that the moving push rod 750 moves outward and extends into the card interface 121, thereby fixing the guide plate assembly 200. When the connecting seat assembly 100 and the guide plate assembly 200 are separated as needed, the valve on the second air pipe 712 is opened, and the moving push rod 750 moves inward until the moving push rod 750 contacts the spring connecting plate 740 and the first spring 730 is partially compressed. When the plug 600 needs to be firmly connected, the air pressure in the d area of ​​the two lifting assemblies 800 is usually increased to 5 bar at the same time, at which time the piston rod 840 moves downward, the rotating plate 920 deflects, the follower frame 930 moves downward, and the follower frame 930 moves horizontally toward the center of the housing assembly 300. When the plug 600 needs to be unlocked, the valves on the two fourth air pipes 812 are opened, the piston rod 840 moves upward, and the piston rod 840 reaches balance under the combined action of its gravity and the second spring 830.

[0037] The present invention also provides a method for fixing an audio coaxial socket with a switch, the method comprising a method S1 for fixing a guide plate assembly and a method S2 for firmly connecting a plug; The guide plate assembly is fixed in the method S1, which comprises the following steps: S11, align the third through hole 203 and the positioning pin hole 131, and position the connecting seat assembly 100 and the guide plate assembly 200 by the positioning pin 205; S12, placing the transverse moving assembly 700 at the position specified by the first groove 201, at which time the air pressure values ​​in the a area and the b area of ​​the transverse moving assembly 700 are equal; S13, opening the valve on the second air pipe 712, increasing pressure to the area b of the traverse assembly 700 in step S12 through the second air pipe 712, pushing the moving push rod 750 to move outward and extend into the card interface 121; S14, after the pressure is increased to a preset value, the valve on the second air pipe 712 is closed; S15, perform the same operations on the other three transverse movement assemblies 700 according to the above steps S13 and S14, so that all the moving push rods 750 move outward and extend into the card interface 121, thereby fixing the guide plate assembly 200.

[0038] It should be noted that, during disassembly, the valves on all the second air pipes 712 are opened, the movable push rods 750 are all moved toward the direction of the first spring 730 , and all the movable push rods 750 are not in contact with the card interface 121 .
